Description

Knob formula barker

Technical Field

The invention belongs to the technical field of cable peeling, and particularly relates to a knob type peeler.

Background

Along with the continuous development and progress of society, the scale of power distribution network construction is also continuously enlarged, and the workload of operation and maintenance of the power distribution network is increased day by day. In order to improve the power supply reliability and reduce the number of households in power failure, the working importance of live working is gradually increased. In the process of line welding construction, the stripping of the sheath of the insulated conductor, namely the insulating skin, is an important process in the stripping and connection of the conductor. The existing cable peeling mode is divided into manual peeling mode and automatic peeling mode. When the live-wire work is implemented manually by using potential feeding and discharging tools such as an insulating bucket arm vehicle or an insulating platform, not only are operating personnel directly contacted with a live-wire, but also unsafe factors are increased, and meanwhile, the peeling difficulty is high, the operation steps are multiple, the efficiency is low, the operation environment is also easily influenced by the geographical environment, and the peeling is gradually replaced by automatic peeling. For example, a cable knob type peeler is disclosed in a utility model patent with a patent name of "cable knob type peeler" with a publication number of "CN 201829799U", and the knob type peeler is driven by an electric drive to drive a blade to rotate around a cable to realize a circular cutting action by a force output from a speed reduction motor through a crank link mechanism, thereby peeling off an insulation skin. Meanwhile, patent documents with the publication number "CN 108963888A" and the publication number "CN 206432551U" are similarly described, and even the applicant has applied for patent documents with the application number "CN 109119946A" and the name "a cable electric stripping device". According to the existing peeling structure, the peeling device in the market has a common defect that the zero position of the cutter cannot be adjusted on line. Specifically, when the thickness of the insulation sheath of the cable is equal and the outer diameter of the cable is different, different feed amounts need to be adjusted to achieve the same cutting depth, so as to achieve the effect of completely stripping the insulation sheath without damaging the core. However, the zero point position of the cutter of the existing knob type barker can only be preset and adjusted off-line; when the cable is stripped, the cable only needs to be inserted into the stripping clamp frequently, and whether the preset feed amount is enough or not is observed visually in the process. Once the excessive or insufficient cutting feed is found, the knob type peeler needs to be taken down from the cable, the cutting feed of the cutter at the knob type peeler is adjusted to be deep or shallow a little, and then the visual observation process is repeated until the cutting feed of the cutter is consistent with the actual cutting feed of the cable. Every model cable is skinned once, all goes on many times along with above-mentioned adjustment operation, and obviously the accommodation process is very loaded down with trivial details, and the cable that seriously influences reality skins efficiency. In addition, another outstanding problem in the prior art is the combined adjustment of the feed depth and the feed angle of the tool. Since the sheath of the insulated conductor, also known as the insulation sheath, is usually made of high-strength polyethylene material and has very large thickness and hardness, the cutter is required to have a proper depth of cut and a specific optimal angle of cut, so as to realize a reliable function of stripping the insulation sheath. The existing peeling structure often neglects the adjustment of the cutting feed angle, and focuses on the adjustment of the cutting feed depth. Obviously, by means of the single feed angle adjusting operation, when the angle of the cutter is too large, once the hardness of the cable insulation sheath to be stripped is higher, the bending and breaking phenomena of the cutter can even occur. When the angle of the cutter is too small, the efficiency is low when the peeling operation of the thick insulating skin is carried out, the knob type peeler is required to repeatedly cut the wire core with multiple power, and the requirement of efficient modern peeling is not facilitated. If the problem is solved, the mode that the cable with a specific model is matched with the knob type barker with the cutter with a specific angle can be only relied on, but the actual barking cost is obviously increased, the single carrying amount of an operator is increased, and a lot of troubles are brought to the actual operation. Meanwhile, when the cable is stripped, the stripping clamp at the knob type stripper is not only required to clamp the cable, but also required to rotate around the cable to strip the cable, so that how to clamp the cable with proper force is also a technical problem to be solved urgently in recent years in the field.

The invention has the beneficial effects that:

1) on the basis of the structure of the existing barker, the invention provides a manually-controlled zero reference adjusting structure, so that the function of manually adjusting the cutter feed amount of a cutter can be flexibly realized according to the diameter of a current cable to be clamped. Specifically, when the knife depth adjusting knob is manually screwed to drive the knife depth adjusting bolt until the annular bulge at the knife depth adjusting bolt is matched with the pressing plate together to oppositely clamp the knife depth adjusting threaded seat, the knife tip of the knife and the reference part are positioned on the same horizontal line; meanwhile, the cutter depth adjusting threaded seat is fixedly connected with the zero-position reference sliding plate, so that the zero-position reference sliding plate, the reference part, the cutter depth adjusting threaded seat and the cutter depth adjusting sliding block are fixedly connected with one another to form an integrated structure, and elastic floating motion can be generated relative to the upper clamping plate and the pressing plate under the action of the elastic compression damping piece. In case the cable is lived in the parcel of punch holder cooperation lower plate, reference portion can be promoted and the come-up under the effect of elasticity compression damping piece this moment, simultaneously because cutter and reference portion have integrated, consequently the cutter also can produce synchronous come-up action, accomplishes zero-position reference correction operation promptly. And then, the cutter depth adjusting knob is used for driving the rotating sleeve to rotate, so that the cutter depth adjusting bolt generates spiral descending motion, and the cutter can slowly cut into the cable insulation skin along with the integral rotation of the peeling clamp under the action of the elastic restoring force of the elastic compression damping piece. When the cutter depth adjusting bolt moves downwards for one centimeter, the cutter can sink one centimeter absolutely relative to the reference part or the uppermost bus of the cable insulating sheath, finally the consistent program adjustment of the cutter feeding amount and the actual required cutter depth of the cable is realized, and the absolute cutter depth adjusting effect is achieved. Certainly, in actual operation, the contact position of the cutter and the reference part does not necessarily need to be the uppermost bus of the cable insulation sheath, and only the action paths of the cutter and the reference part are arranged along the radial direction of the cable, and the contact position of the relative cable insulation sheath is the same bus as the cable insulation sheath, which is not described herein again.

Under above-mentioned structure, when the sword depth adjust knob constantly orders about the rotating sleeve and rotates and make the sword depth adjust bolt constantly down, the cutter can constantly deepen the absolute depth of eating of relative cable insulating skin. Once the tool tip just extends into the state of completely stripping the cable insulation skin and the wire core begins to be exposed, the rotary tool depth adjusting knob can be stopped so as to keep the current tool depth and achieve the aim of continuously and perfectly cutting the cable insulation skin. Of course, the type of the cable to be stripped is preferably predicted to obtain the current insulation skin depth of the cable, and then the rotation number of the cutter depth adjusting knob is manually controlled to ensure that the cutter tip can just strip the insulation skin of the cable to the exposed degree of the cable core, namely, the cutter tip stops continuously extending into the cable core, so that the stripping efficiency is ensured.

2) When the cable clamping device is used for clamping and fixing cables, the synchronous approaching and separating actions of the upper clamp seat relative to the lower clamp seat can be realized through the forward and reverse rotation actions of the opening and closing driving motor. In practical operation, the invention is additionally provided with a sensing part on the basis of the structure, the sensing part can adopt the existing sensing structure such as a travel switch and even an electronic sensor, so that the position of the sensing part is adjusted through the travel action of the sensing part in the vertical direction of the lead, and the function of adjusting the distance between two groups of clamp seats of the peeling clamp when the clamping action is generated is realized. When the cable needs to be clamped, the position of the sensing part is adjusted, and because the upper clamp seat and the lower clamp seat are synchronously moved by the aid of the bidirectional screw rod in the prior art, when the opening is adjusted during clamping, the sensing part at the upper clamp seat can generate sensing stop movement. In other words, the position stop function of the upper clamp seat can be realized through the lifting and positioning actions of the sensing part every time the cable is clamped and fixed. Every when the upper clamp seat moves relative to the lower clamp seat in opposite directions to the matching part to contact or sense the sensing end of the sensing part, the opening and closing driving motor stops acting, so that the peeling clamp is guaranteed to hold the cable with the most appropriate force. When the cable is peeled, the peeling clamp does not need to embrace the cable, and simultaneously needs to wind the cable to generate rotary peeling action, so the proper force needs to be adjusted timely and pertinently according to the mechanism provided by the invention. Every time the sensing part descends by one centimeter, the clamping gap between the upper clamp seat and the lower clamp seat which synchronously act in opposite directions is reduced by two centimeters, the diameter of the corresponding clamped cable is two centimeters smaller than that of the original clamped cable, and the like, so that the use is very convenient.

3) Further, the operation mode of the sensor unit can be realized by various structures in actual use: if the sensing part is driven by the air cylinder to generate vertical lifting action, the function of changing the position of the sensing end at the sensing part is realized, and the program adjustment of the stop position of the corresponding clamp seat is further realized. The sensing part as a sliding block can be driven to vertically lift in a crank rocker mode, so that the corresponding adjusting effect is achieved. The invention preferably adopts the action of the opening adjusting screw rod and the screw rod slide block of the sensing part to realize the purpose of manual position adjustment of the corresponding clamp seat: during actual operation, the rotary motion can be converted into the linear up-and-down reciprocating motion of the sensing part through the opening adjusting screw rod through the rotary motion of the opening adjusting knob, the structure is simple, the implementation is easy, and the cost performance is high.

4) The sensor is characterized in that the sensor comprises a rotary sleeve, a sensing part and an opening adjusting screw, wherein the rotary sleeve is arranged on the base body, the sensing part is arranged on the base body, and the opening adjusting screw is matched with the opening adjusting screw to ensure the reliability and accuracy of the vertical lifting action of the sensing part. In addition, the rotary sleeve is matched with the rotary hole by means of the small shaft diameter section; on the other hand, the top end of the small shaft diameter section forms spline fit with the opening adjusting knob; therefore, the shaft shoulder of the rotary sleeve and the bottom end surface of the opening adjusting knob are clamped on the sealing plate in opposite directions, so that the rotary sleeve is reliably matched on the rack and simultaneously ensures the stable rotation function of the rotary sleeve, and the rotary sleeve is very convenient to disassemble and assemble.

5) On the basis of the structure, the observation hole is matched with the scales and the indicating arrow, so that when the sensing part generates vertical lifting motion, the indicating arrow at the corresponding sensing head can generate vertical lifting motion relative to the scales at the static machine frame. The corresponding scales are drawn up according to the sizes of the cables which are commonly used in the field. During actual operation, the opening adjusting knob can be rotated pertinently only by looking at the type of the cable needing to be peeled at a glance, and then the cable is lifted to the scale position aligned with the cable corresponding to the type through the indicating arrow, so that the position calibration purpose of the sensing part is achieved. Once the position of the sensing part is determined, the stop position of the corresponding upper clamp seat when the upper clamp seat descends can be determined, and then the purpose of determining the size of the clamping opening of the upper clamp seat relative to the lower clamp seat can be achieved, so that the corresponding cable can be clamped by the most appropriate force, and the subsequent peeling process is facilitated.

6) As described above, the sensing portion may be actually implemented using a structure such as an electronic sensor. The present invention preferably uses a travel switch to simplify its structure. When a travel switch is selected as the sensing part, a horizontal poking tongue should be arranged on the back surface of the upper clamp seat to form a matching part. In actual operation, the arrangement of the sensing part can ensure that the cable can be clamped by proper cohesion force when the two clamp seats synchronously and closely act; meanwhile, the invention also adds a lower travel switch to achieve the purpose of limiting the maximum opening amplitude when the two clamp seats are separated from each other. Through the limitation of the maximum opening amplitude, the occurrence of useless work can be effectively avoided, and the actual use efficiency of the invention is effectively ensured. Of course, when the peeling clamp is used specifically, the lower clamp seat can be used as a matching piece of the sensing part, and the upper clamp seat is used as a matching piece of the lower travel switch, so that the purpose of integrally controlling the opening and closing amplitude of the peeling clamp can be achieved, and the details are omitted.

7) For the opening adjusting screw rod, the opening adjusting screw rod and the rotary sleeve are matched in a detachable spline mode, so that the convenient dismounting function of the opening adjusting screw rod is ensured, and the rotary sleeve can reliably transmit torque to the opening adjusting screw rod after being mounted.

8) In the reference part, during actual operation, a straight rod or the like can be used for realizing the contact function relative to the cable insulation skin, or a rectangular block with a ball at the front end is used for realizing the contact matching effect. The zero-position reference bearing is preferably adopted to realize the reference calibration function: this is because zero-position reference bearing can not only realize the contact effect of relative cable insulating skin, thereby simultaneously when the relative cable of anchor clamps of skinning is rotatory constantly peels off insulating skin, zero-position reference bearing also can produce bearing rolling action relative to the cable surface to reduce the rotation resistance of the relative cable surface of anchor clamps of skinning, effectively promote the convenience and the efficiency of skinning of whole operation of skinning.

9) And further, the upper clamping plate and the lower clamping plate preferably realize the embracing function of the opposite cables by mutually matching the V-shaped embracing surfaces of the V-shaped embracing plates. When the V-shaped holding plate is arranged at the bottom end face of the upper clamping plate, if the coverage area of the V-shaped holding plate is enlarged, the action path of the reference part is interfered; if the coverage area of the V-shaped holding plate is reduced, the holding effect of the opposite cable may be reduced. According to the invention, the position-giving port is directly formed on the V-shaped holding plate for the reference part to normally pass through, so that the coverage area of the V-shaped holding plate is ensured, and the normal zero position reference correction function of the reference part is ensured, thereby achieving multiple purposes.

10) For the elastic compression damping part, structures such as an elastic damping air bolt and even a hydraulic damping rod can be adopted. The invention preferably adopts a traditional guide post and spring matching structure, so that two groups of compression springs are matched through two guide posts, and the purpose of accurate vertical lead guiding of the knife depth adjusting slide block is ensured while the elastic matching function of the knife depth adjusting slide block relative to the pressing plate is ensured.

11) For the matching structure of the zero-position reference sliding plate and the upper clamping plate and the cutter depth adjusting sliding block and the zero-position reference sliding plate, the reliable vertical sliding matching function of lead can be ensured through the zero-position reference guide rail and the cutter depth adjusting guide rail, so that the purpose of online sliding adjustment of the lead is ensured.

12) Furthermore, the cutter holder is used as a fixing body, the cutter head is used as a working end, and the adjusting handle is used as a middle connecting piece, so that the purpose of adjusting the arc-shaped action of the cutter head relative to the cutter holder is achieved. The guide rail sliding block which is in arc-shaped motion in the guiding direction is formed between the adjusting handle and the tool apron in a matching relation, and the circle center of an arc-shaped motion path generated by the adjusting handle relative to the tool apron is the point where the tool tip of the tool bit is located; therefore, no matter how the adjusting handle is driven, the cutter head always generates arc-shaped rotating action taking the cutter point as the circle center, thereby not only realizing the function of changing the cutting-in angle of the cutter edge, but also ensuring that the cutter edge always can accurately abut against the initial cutting-in point preset at the insulating skin no matter how the cutter head is adjusted, and finally ensuring that the invention can stably and reliably realize the purpose of quickly stripping the insulating skin under the subsequent action of the zero reference adjusting assembly.

13) To the guide rail cooperation structure between regulation handle and blade holder, can have multiple realization scheme during the in-service use: if the guide sliding rail is arranged at the adjusting handle, and the tool apron is provided with the sliding block structure, the guide matching function of the tool apron is realized through the matching of the guide sliding rail and the sliding block. Also can arrange the arc hole of through type in regulation handle department to thereby set up the locating pin on the blade holder and stretch into in the arc hole, in order to realize its radian direction function. The invention preferably uses a matching structure of the groove and the convex edge, and the matching fixing screw is fixedly connected and matched with the thread of the cutter holder so as to ensure the online adjusting function of the adjusting handle relative to the cutter holder. On one hand, the corresponding matching structure of the groove and the convex edge ensures that the whole processing process tends to shallow processing and the processing technology requirement is lower. On the other hand, the arc-shaped fixing hole is matched with the matching structure of the fixing screw, so that the action surface on the whole structure is positioned at one side of the cutter holder, the operation of adjusting the cutter holder can be completely finished at one side of the cutter holder, and the cutter holder is particularly suitable for being used in a narrow working environment where the cutter holder is positioned. In addition, the corresponding grooves and the convex ribs are matched to form a group of arc-shaped actuating mechanisms, and the fixing screws matched with the arc-shaped fixing holes actually form a group of arc-shaped actuating mechanisms. Above-mentioned double arc guide mode, the accurate arc swing function of realization tool bit that can maximize to ensure the tool bit all the time when carrying out the blade angle change of relative insulating skin, the knife tip of the cutting edge below of tool bit is died all the time at the initial point of cut-in department that insulating skin department predetermine, and its operational reliability is extremely high.

14) Furthermore, the cutter head can realize the rotation adjusting function around the axis of the cutter head through the unique cylindrical structure of the cutter head when the cutter head has the function of adjusting the cutting-in angle of the cutting edge. Through the rotary adjustment, on one hand, the vertical height of the arc-shaped cutting edge of the tool bit can be always ensured to be larger than the total thickness of the insulation skin when the cutting is fed, on the other hand, the best lateral chip guiding and chip removing effect can be achieved, and the purpose of optimized insulation skin cutting can be achieved by matching with the adjustment of the cutting angle of the cutting edge. In addition, the cylindrical or semi-cylindrical cutter head can generate huge cutting force when cutting the insulating skin, and the cutter head can also have enough rigidity and strength to bear the reverse force of the cutter head, so that the actual service life of the integral component is ensured.

15) The equipotential elastic sheet is initially supported against the surface of the cable insulation skin due to the existence of the insulation skin on the surface of the cable, and therefore the equipotential elastic sheet can only elastically abut against the surface of the cable insulation skin due to the action of the hoop cable of the peeling clamp. When the cutter is skinned, the cable insulation skin is gradually removed and the sinle silk is exposed, and the equipotential elastic sheet can move to contact the sinle silk because of the elastic restoring force of the equipotential elastic sheet, and the high-voltage current at the sinle silk is connected with the circuit board of the robot to form an equipotential operation effect, thereby ensuring the automation work purpose of the robot.

Detailed Description

For ease of understanding, the specific construction and operation of the present invention is further described herein with reference to FIGS. 1-23:

the invention mainly comprises a peeling clamp 50 and a driving unit 40; after the cable stripping device is assembled, the cable stripping device can be finally fixed on external devices such as an axial follow-up mounting frame, a robot arm and even a handheld insulating rod through the adapter frame, so that the aim of cable stripping at high altitude is fulfilled. The combination of the peeling clamp 50 and the driving unit 40 is disclosed before the present application and will not be described again, and the peeling clamp 50 modified is mainly described herein.

The peeling tool 50 includes a zero reference adjustment assembly, a feed angle adjustment assembly, a tool opening adjustment assembly, an axial displacement helix angle adjustment assembly, a peeling device 52w, an equipotential spring 53a, and the like.

The following description is made in order:

firstly, a zero reference adjusting component:

the specific construction of the zero reference adjustment assembly is shown with reference to figures 1-4 and 6-10 and in use can be assembled directly with the tool bit 56 and the rear threaded slider 50a to form the upper clamp mount 52. Referring to fig. 6-8, the zero reference adjustment assembly includes, from left to right, an upper clamp plate 52j, a zero reference guide rail 52u, a zero reference slide plate 52a, a knife depth adjustment guide rail 52v, a knife depth adjustment slider 52b, and a reference portion 52 k. A reference positioning plate 52o is horizontally and outwardly protruded on the right side of the tool depth adjusting slider 52b, and a vertical reference hole is formed in the reference positioning plate 52 o. In the layout structure shown in fig. 8, a tool depth adjusting bolt 52f is fitted to the hole axis at the vertical reference hole; further, a knife depth adjusting screw seat 52d, a pressing plate 52c, an elastic compression damping member 52e, a rotary sleeve 52g and a knife depth adjusting knob 52h are provided in this order upward along the axial direction of the knife depth adjusting bolt 52 f.

During the specific assembly:

as shown in fig. 6-8, the upper clamping plate 52j serves as a framework of the upper clamp seat 52, and a V-shaped holding plate 52q is disposed at the bottom end thereof, and a straight-angled bent plate structure is integrally formed between the top end thereof and the pressing plate 52c by means of bolt fastening. The zero position reference guide rail 52u is fixedly connected to the left side of the upper clamping plate, that is, the outer side plate surface, so that the zero position reference sliding plate 52a positioned on the outer side plate surface of the upper clamping plate can form a guide rail matching relation with the upper clamping plate, wherein the guide direction of the guide rail is vertical to lead, through the zero position reference guide rail 52 u. Similarly, a blade depth adjusting guide rail 52v is arranged on the outer side plate surface of the zero position reference sliding plate 52 a; and the knife depth adjusting slide block 52b positioned at the outer side plate surface of the zero position reference slide plate 52a forms a guide rail matching relation with the zero position reference slide plate 52a, wherein the guide direction of the guide rail is vertical to lead through the knife depth adjusting guide rail 52 v. The top end surface of the zero-position reference sliding plate 52a and the knife depth adjusting threaded seat 52d also form an integral right-angle bent plate structure, and the bottom end surface of the zero-position reference sliding plate 52a is connected with a reference part 52k, namely a zero-position reference bearing, through a bearing seat 52 p.

As shown in fig. 6 to 8, a guide post 52s is vertically extended from the top end of the blade depth adjusting slider 52b, and the top end of the guide post 52s penetrates the pressing plate 52c to form a guiding fit with the guide hole of the pressing plate 52 c. The elastic compression damping member 52e can be coaxially mounted on the guide post 52s by means of, for example, a compression spring or a damping air post, so as to realize the elastic accumulation and separation of the blade depth adjusting slider 52b with respect to the pressing plate 52c under the elastic restoring force. The bottom end of the blade-depth adjusting slider 52b is fixed to the blade seat 56a of the cutter 56 by bolts as shown in fig. 6 to 8. In practice, referring to the structure of the tool seat 56a shown in fig. 15-20, a corresponding waist-shaped assembling hole is provided on the tool seat 56a, so as to achieve a certain degree of horizontal tool adjustment when the tool depth adjusting slider 52b is engaged.

As shown in fig. 6-8, a horizontal reference positioning plate 52o is protruded from the outer plate surface of the tool depth adjusting slider 52b, a vertical reference hole is formed in the reference positioning plate 52o, and a radial protrusion 52l in the shape of a protruding ring is coaxially protruded from the bottom end surface of the tool depth adjusting bolt 52 f; the upper ring surface of the radial bulge 52l and the lower plate surface of the reference positioning plate 52o form a one-way spigot fit. Meanwhile, after the blade depth adjusting bolt 52f is in threaded fit with the blade depth adjusting threaded seat 52d, the top end surface of the blade depth adjusting bolt 52f also coaxially penetrates into the cylindrical cavity of the rotating sleeve 52g, and a torque transmission type fit structure which can axially slide and circumferentially limit is realized through the fit of the limiting protrusion 52n and the limiting groove hole 52m as shown in fig. 7. The top end of the rotating sleeve 52g is fixedly connected to the power output shaft of the knife depth adjusting knob 52h located on the upper plate surface of the pressing plate 52c through a radial fixing structure capable of transmitting torque, such as a set screw structure or even a spline fit, so as to ensure the torque transmission function of the rotating sleeve 52g and the knife depth adjusting bolt 52 f.

When an operator manually twists the blade depth adjusting knob 52h to rotate the same, an axial downward force is applied to the blade depth adjusting bolt 52f by rotating the sleeve 52g, so that the blade tip of the blade 56 located at the blade depth adjusting slider 52b moves downward, thereby realizing the depth cutting function of the cable insulation skin. When the knife depth adjusting knob 52h continuously drives the rotating sleeve 52g to rotate and the knife depth adjusting bolt continuously descends, the knife 56 continuously deepens the absolute knife depth relative to the cable insulation skin. Through visual judgment of an operator, once the tool tip of the tool 56 just extends into the state of completely stripping the cable insulation sheath and the wire core begins to be exposed, the tool depth adjusting knob 52h rotates to the right position and keeps the original position still, so that the purpose of continuously and perfectly cutting the cable insulation sheath is achieved by maintaining the current tool depth. Of course, it is more preferable to predict the type of the cable to be stripped, so as to obtain the current insulation sheath depth of the cable, and further, by controlling the number of revolutions of the blade depth adjusting knob 52h, it is ensured that the blade tip of the blade 56 can just strip the insulation sheath of the cable to the extent that the cable core is exposed, that is, the blade tip stops extending continuously, so as to ensure the stripping efficiency.

Naturally, in actual operation, the above-mentioned visual operation mode may be replaced by an induction operation mode such as a conventional photoelectric sensing portion like a camera sensing portion, or even an existing conventional detection means such as discharge detection, electromagnetic field induction, etc. may be adopted, and these means, even the signal transmission and receiving and transmitting modes thereof, are conventional operation modes in the electronic sensing field, and will not be described herein again.

Secondly, a feed angle adjusting component:

for the feed angle adjustment assembly, the structure thereof is shown with reference to fig. 1-4 and 15-20. The feed angle adjusting unit includes a cutter head 56b serving as a mounting base for cutting the insulation skin, a holder 56a serving as a mounting base for the cutter head 56b, and an adjustment handle 56c for engaging the cutter head 56b with the holder 56 a. The tool seat 56a is fixed to the bottom end surface of the tool depth adjusting slider 52b of the zero reference adjusting assembly by means of a bolt fitting or other known fitting means, so as to be capable of ascending and descending together with the tool depth adjusting slider 52 b.

The adjusting lever 56c has a trapezoidal plate shape as shown in fig. 15 to 16, and an inner plate surface of the adjusting lever 56c constitutes a contact surface for engaging with a vertical engagement surface of the tool rest 56 a. The top edge of the trapezoid of the adjustment handle 56c extends toward the tool seat 56a to form a fitting plate 56h, and the surface of the fitting plate 56h is perpendicular to the surface of the adjustment handle 56 c. In the structure shown in fig. 15-20, it can be seen that the abutting surface of the adjusting handle 56c is convexly provided with an arc-shaped convex rib 56d, the vertical mating surface of the tool seat 56a is correspondingly provided with an arc-shaped groove 56e, and the arc-shaped extending paths of the arc-shaped convex rib 56d and the arc-shaped groove 56e are positioned on the same circle which takes the tool tip of the tool bit 56b as the center of circle and the distance between the tool tip of the tool bit 56b and the corresponding groove or convex rib as the radius. Meanwhile, an arc-shaped fixing hole 56g is horizontally arranged at the position of the adjusting handle 56c in a penetrating mode, and a concentric circle layout is formed between the radian extending path of the arc-shaped fixing hole 56g and the radian extending path of the arc-shaped convex rib 56 d. The fixing screw 56f horizontally penetrates the arc-shaped fixing hole 56g, and the top end of the fixing screw 56f is in threaded fixed connection with the vertical matching surface of the tool apron 56a, so that the adjusting handle 56c is horizontally pressed and fixed on the tool apron 56a by using the nut end of the fixing screw 56 f.

The profile of tool tip 56b is also taught: as shown in fig. 15-19, cutting-head 56b actually assumes a downwardly inclined cylindrical configuration in profile. The rear section of tool bit 56b forms the shank end of tool bit 56b, while the top end of the front section of tool bit 56b is coaxially recessed with a counterbore having an internal chamfer disposed at the orifice of the counterbore. The cutting head 56b is cut by a cutting plane coinciding with the axis of the cutting head 56b so that the front section of the cutting head 56b has a semi-cylindrical structure, and the inner chamfer cut at the counter bore at this time forms a semi-circular arc-shaped blade 56 j. The structure of the cutter head 56b can always ensure that the vertical height of the arc-shaped cutting edge of the cutter head 56b is greater than the total thickness of the insulating skin when cutting is carried out; on the other hand, the cutting device is also favorable for achieving the best lateral chip guiding and chip discharging effect, and the optimal insulating skin cutting purpose can be achieved by matching with the adjustment of the cutting-in angle of the cutting edge 56 j. In addition, the cylindrical or semi-cylindrical cutting head 56b generates a large cutting force when cutting the insulation sheath, and the cutting head 56b itself can have sufficient rigidity and strength to bear the reverse force thereof, so as to ensure the actual service life of the integral member.

Thirdly, adjusting the opening of the clamp:

the structure of the clamp opening adjustment assembly is shown with reference to fig. 2-5; rear threaded sliders 50a are uniformly arranged on the back surfaces of the upper clamp seat 52 and the lower clamp seat 53 so as to form a threaded fit relation with the screw rod segments of the bidirectional screw rod 54, so that the upper clamp seat 52 and the lower clamp seat 53 can generate opposite and opposite actions parallel to the axis of the bidirectional screw rod 54 under the driving of an opening and closing driving motor 55 or other power equipment. In order to ensure the operational stability of the upper jig base 52 and the lower jig base 53, the frame 51 is further provided with a vertical guide rail 51i, and the rear screw slider 50a is fitted to the vertical guide rail 51i through a corresponding guide rail of the vertical slider 51 j.

In practice, the present invention is designed with a set of portable adjustment devices for manual adjustment of the peeling clamp 50, i.e., the clamp opening adjustment assembly described above. As shown in fig. 5 and fig. 11-14, the clamp opening adjustment assembly includes an opening adjustment knob 51k, an upper straight V-shaped groove 51a, a rotary sleeve 51j, a sensing portion 51n, an opening adjustment screw 51m, a lower support block 51f, and a lower stroke switch 51h, which are sequentially arranged from top to bottom. In actual operation, after the vertical guide 51i is mounted on the inner plate surface of the C-shaped plate-like frame 51 as shown in fig. 4 to 5, the upper right-angled V-shaped groove 51a and the lower support block 51f are mounted on the outer plate surface of the frame 51 in this order from top to bottom. Meanwhile, the upper right-angle V-shaped groove 51a can be separated into a lower segment for guiding the sensing portion at the lower portion and an upper segment with a rotary hole at the upper portion, so as to facilitate easy assembly of the opening adjusting screw 51m and the rotary sleeve 51 j. And a lower right-angle V-shaped groove 51g is correspondingly concavely arranged at the lower supporting block 51 f. The upper right-angle V-shaped groove 51a and the lower holder 51f may be mounted on the outer panel surface of the frame 51, and the opening adjustment knob 51k, the rotary sleeve 51j, the sensing part 51n, the opening adjustment screw 51m, and the lower stroke switch 51h may be mounted in the order shown in fig. 5.

In the peeling process, the arrangement of the sensing part 51n can ensure that the cable can be embraced with proper embracing force when the two clamp seats synchronously move close to each other; meanwhile, the invention is additionally provided with a lower travel switch 51h to achieve the purpose of limiting the maximum opening range when the two clamp seats are separated from each other. Specifically, in the assembled state of fig. 5 and 11-14, the upper clamp seat 52 is engaged with the sensing portion 51n, and the lower clamp seat 53 is engaged with the lower stroke switch 51h, the sensing portion 51n can be engaged with the horizontal shifting tongue 50b at the upper clamp seat 52, so as to achieve the function of calibrating the minimum value of the opening of the opposite movement, i.e., the closing movement, of the peeling clamp 50. The lower stroke switch 51h can not only refer to the sensing part 51n to ensure the purpose of guiding and adjusting action, but also can realize the function of calibrating the maximum opening value of the peeling clamp 50 in the separation action, namely the opening action, by matching with a fixed-point screw of the horizontal poking tongue 50b at the lower clamp seat 53, and even the lower stroke switch 51h can be directly fixed on the lower supporting block in a threaded manner to realize fixed-point fixation. During the screw cooperation operation to the fixed point specifically, can run through on the lower travel switch 51h and set up the location and walk the hole, but lower right angle V type groove 51g department can lead vertically set up multiunit location mating holes according to the preface to through the pertinence of location mating screw wear establish, thereby realize down travel switch 51h highly fixed function of right angle V type groove 51g vallecular cavity down relatively. The operator only needs to look at the type of the cable to be stripped at a glance, and can correspondingly rotate the opening adjusting knob 51k, and then move to align with the scale 51d corresponding to the cable of the type through the indication arrow 51e as shown in fig. 4 and fig. 11, and finally realize the purpose of conveniently calibrating the position of the sensing part 51n through timely observation of the observation hole 51 c. Once the position of the sensing part 51n is determined, the stop position of the corresponding upper clamp seat 52 when the upper clamp seat 52 descends can be ensured, and accordingly the purpose of determining the minimum value of the clamping opening of the upper clamp seat 52 relative to the lower clamp seat 53 can be achieved; the fixed lower stroke switch 51h ensures the purpose of limiting the maximum opening of the peeling clamp 50 so as to facilitate the subsequent peeling process.

Fourthly, adjusting the spiral angle of the axial displacement:

the axial displacement helix angle adjusting component is arranged to achieve the purpose of adjusting the axial displacement helix angle when the cable is peeled by the peeler, so that the control function of the axial movement speed of the cable during peeling is guaranteed, and the peeling efficiency is maximized. Specifically, as shown in fig. 21 to 23, the axial displacement helix angle adjusting assembly includes a blind hole 53b recessed in the groove cavity of the V-shaped embracing plate 52q of the lower fixture seat 53, so that the edge of the tooth-shaped guide edge 53d of the guide knife 53c can be adjusted by the effective fit between the square plate-shaped fixed guide knife 53c and the hole cavity of the blind hole 53b as shown in fig. 23. On one hand, a matching blind hole 53b is directly arranged in a groove cavity of the V-shaped holding plate 52q, namely a V-shaped holding surface in a concave mode, so that the purpose of effectively accommodating a guide knife 53c with a certain thickness can be achieved, and the guide knife 53c can not influence the axial movement of a cable. On the other hand, although the guide blade 53c is recessed in the mating blind hole 53b, the tooth-shaped guide rib 53d may protrude from the cavity surface of the V-shaped holding plate 52q, so that the edge of the tooth-shaped guide rib 53d may be used to cut into the cable insulation sheath. In practice, as shown in fig. 21-22, the present invention can employ a first adjusting screw 53e to cooperate with the first through-going counter bore 53g to form a positioning shaft, and a second adjusting screw 53f to cooperate with the second through-going counter bore 53h to ensure the adjusted fixing function of the guiding blade 53 c. The corresponding adjusting screw can be hidden in each through counter bore so as to avoid the action interference phenomenon between the position of the protruding adjusting screw and the cable.

Fifthly, a skin guiding device:

the skin guiding device 52w is in a bell mouth shape with a large opening facing upwards, and the small-caliber end of the skin guiding device 52w is connected with the vertical plate to form a fastening fit with a preset assembling hole of the cutter 56, so that the skin guiding device 52w is stably assembled. The leather guide 52w functions to guide the insulating leather in a spiral strip shape where the insulating leather is cut by the cutter 56. When the cutter 56 cuts the cable insulation sheath, the spiral strip-shaped cut insulation sheath is directly guided out of the practical working range of the present invention by the sheath guiding device 52w as shown in fig. 1-4, and then naturally falls under the action of gravity, so as to avoid the hard interference of the hard insulation sheath with the normal action of the present invention along with the progress of the cutting process.

Sixthly, equipotential elastic sheets:

the purpose of the equipotential elastic sheet 53a is to gradually remove the insulation sheath of the cable and expose the wire core when the cutter 56 peels off, and at this time, the equipotential elastic sheet 53a will move to contact the wire core due to its elastic restoring force and connect the high-voltage current at the wire core with the circuit board of the robot, so as to form an equipotential operation effect. The specific shape of the equipotential elastic sheet 53a can refer to the C-shaped sheet shown in fig. 4, one end of which is fixed in the concave groove at the notch of the V-shaped holding plate 52q shown in fig. 4, and the other end of which can be pressed to generate an elastic pressing action along the groove direction of the concave groove and restore the original state when the pressure is released. The arch back of the equipotential elastic sheet 53a should protrude out of the groove surface of the V-shaped holding plate 52q for matching with the cable, and the arc back should be in contact with the cable core; of course, the specific protruding height of the arch back can be adjusted as required according to the needs of the field, and will not be described in detail here.

To facilitate a further understanding of the invention, a specific workflow of the invention is given herein as follows:

cable cohesion flow:

when the cable needs to be stripped, firstly, the clamp opening adjusting assembly is operated: the operator rotates the opening adjustment knob 51k according to the type of the cable to be stripped, so as to drive the sensing part 51n to float up and down until the indication arrow 51e at the back of the sensing part 51n at the observation hole 51c can point to the scale 51d corresponding to the current type of the cable as shown in fig. 11. Then, the opening and closing driving motor 55 starts to operate, and drives the bidirectional screw 54 to rotate, so that the upper clamp seat 52 and the lower clamp seat 53 of the peeling clamp 50 generate opposite motions under the action of the screw threads of the bidirectional screw 54 until the V-shaped holding plate 52q at the upper clamp seat 52 and the V-shaped holding plate 52q at the lower clamp seat 53 embrace the cables oppositely. When the horizontal shifting tongue 50b at the upper clamp seat 52 touches the sensing end of the sensing part 51n at the preset height on the frame 51, the opening and closing driving motor 55 stops moving, and the cable is stably held by the peeling clamp 50. Of course, when the opening and closing driving motor 55 rotates reversely to drive the peeling clamp 50 to open, the lower travel switch 51h fixed in the cavity of the lower right-angle V-shaped groove 51g by the bolts in advance responds, and waits for the horizontal shifting tongue 50b at the lower clamp seat 53 to move downwards and touch the switch end of the lower travel switch 51h, so as to stop the opening and closing driving motor 55, and avoid the unnecessary opening and closing of the peeling clamp 50.

Cable peeling process:

before the cable clasping process is carried out, an operator can judge the thickness of the cable insulating sheath and the cutting angle of the cable according to the current type of the cable, so that the cutting angle of the cutter 56 can be adjusted in advance through the cutting angle adjusting component.

Before the cable is stably held by the peeling clamp 50, the preposed zero reference correction of the cable peeling process can be synchronously performed. When the method is specifically applied to the invention, the operation steps are as follows:

1) zero reference correction: before the cable is held by the V-shaped holding plate 52q, the knife depth adjusting knob 52h is manually rotated in advance, so as to drive the rotating sleeve 52g to move, and further the knife depth adjusting bolt 52f generates a follow-up ascending motion. With the upward movement of the knife depth adjusting bolt 52f, firstly, the top end surface of the radial protrusion 52l at the depth adjusting bolt is gradually pressed on the lower plate surface of the reference positioning plate 52o, and then the reference positioning plate 52o and the zero position reference sliding plate 52a are driven to generate synchronous upward movement until the zero position reference sliding plate 52a is tightly clamped between the radial protrusion 52l and the knife depth adjusting threaded seat 52d, at this time, the position state of the peeling clamp 50 is shown in fig. 9, and the knife point of the knife tool 56 is at the same horizontal plane with the lower end point of the excircle of the zero position reference bearing.

2) And a change position: in the process of clamping the cable by the V-shaped holding plate 52q, the zero position reference bearing, that is, the reference part 52k, is gradually contacted with the cable insulation sheath, and the zero position reference bearing moves upward under the pressing of the cable insulation sheath. Due to the existence of the compression spring, namely the elastic compression damping member 52e, and the zero position reference sliding plate 52a and the knife depth adjusting sliding block 52b are pressed into an integral structure by the radial protrusion 52l of the knife depth adjusting bolt 52f, the knife 56 at the knife depth adjusting sliding block 52b presses the compression spring to move upwards along with the zero position reference bearing at the zero position reference sliding plate 52a, so that the change position step is completed. In the above zero-finding process, the knife tip of the knife 56 is always in a state of just contacting with the cable insulation sheath, as shown in fig. 9;

3) adjusting the absolute feed amount: after the change position step is completed, the cutter depth adjusting knob 52h is screwed to drive the cutter depth adjusting bolt 52f to move downward, so that the radial protrusion 52l moves downward to loosen the clamping of the reference positioning plate 52 o. At this time, under the elastic restoring force of the compression spring, the knife depth adjusting slider 52b integrated with the reference positioning plate 52o moves downward, and the zero reference sliding plate 52a equipped with the zero reference bearing maintains the original position immovably due to the rail fitting relationship with the knife depth adjusting slider 52b and the top bracing action of the cable insulation sheath. Because the axial sliding fit capable of transmitting torque is formed between the limiting groove hole 52m at the position of the rotary sleeve 52g and the limiting protrusion 52n at the position of the knife depth adjusting screw, and the elastic force storage effect of the compression spring exists, the knife depth adjusting knob 52h can rotate in place once, and then the knife 56 at the position of the knife depth adjusting slider 52b is slowly cut into the cable insulation skin by means of the force releasing performance of the compression spring until the specified cut depth is reached, which is specifically shown in fig. 10.

In the above steps, since the type of the cable to be stripped can be predicted, the depth of the insulation sheath of the current cable can be naturally known, and then the number of the rotation cycles of the cutter depth adjusting knob 52h is controlled to ensure that the cutter point of the cutter 56 can just stretch into the depth which completely strips the insulation sheath of the cable and begins to expose the wire core, namely, the stretching action is stopped. Then, the invention is operated to generate action along the axial direction of the cable, and the aim of continuously stripping the insulating sheath of a certain section of the cable with high efficiency can be fulfilled.
