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, operators can directly contact live wires, unsafe factors are increased, the peeling difficulty is high, the operation steps are multiple, the efficiency is low, the operation environment is easily influenced by the geographical environment, and the peeling is gradually replaced by automatic peeling.

However, the thickness of the cable itself varies, and the feed angle of the knife used for peeling also varies: for thick cables, the fixed thread teeth may cause a "blind area" when the cable is stripped, that is, an insulation sheath which cannot be cut exists between cutting paths of two adjacent cutters in the axial direction, thereby causing an undesirable stripping effect. For thinner cables, the fixed thread teeth can cause repeated stripping, that is, the cutting paths of two adjacent cutters in the axial direction are overlapped, so that the stripping purpose is achieved, but the stripping efficiency is not satisfactory.

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 fig. 1-10, which 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. 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 52k, respectively. The right side of the knife depth adjusting slide block 52b is horizontally and outwards provided with a reference positioning plate 52o in a protruding mode, and the position of the reference positioning plate 52o is provided with a vertical reference hole. 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 has a V-shaped holding plate 52q at a bottom end thereof and a right-angled bent plate structure integrally formed with the pressing plate 52c at a top end thereof by fastening bolts. The zero position reference guide rail 52u is fixedly connected to the left side of the upper clamping plate, namely 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 face of the zero reference sliding plate 52a and the depth adjusting screw seat 52d also form an integral right-angle bent plate structure, and the bottom end face of the zero reference sliding plate 52a is connected with the reference part 52k, namely a zero reference bearing, through the bearing seat 52 p.

As shown in fig. 6 to 7, 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 using, for example, a compression spring or a damping air column, so as to realize the action of approaching the elastic accumulation force of the blade depth adjusting slider 52b relative to the pressing plate 52c and the action of separating the elastic releasing force under the elastic restoring force. The bottom end of the tool depth adjusting slider 52b is fixed to the tool seat 56a of the tool 56 by a bolt as shown in fig. 3 and 5. In practice, referring to the structure of the tool seat 56a shown in fig. 11-14, 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. 7-8, 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 a spline fit manner, so as to ensure the torque transmission function of the rotating sleeve 52g and the knife depth adjusting bolt 52 f.

When the tool depth adjusting knob 52h is rotated, an axial downward force is applied to the tool depth adjusting bolt 52f by rotating the sleeve 52g, so that the tool tip of the tool 56 located at the tool depth adjusting slider 52b moves downward, thereby achieving the function of deep cutting of the cable insulation sheath. In the embodiment shown in fig. 2, the core detecting sensor 52i is disposed on the wire feeding side of the upper clamp seat 52 and adjacent to the cutter 56, and the detecting end of the core detecting sensor 52i is directed to the surface of the cable along the radial direction of the cable, so as to achieve the purpose of online monitoring the exposure after the core is stripped. 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. Once the knife tip of the knife tool 56 just extends into the state of completely stripping the cable insulation skin and begins to expose the wire core, the wire core detection sensor 52i collects image signals or other corresponding signals of the wire core at the first time and transmits the signals to the control end, and the knife depth adjusting knob 52h can be stopped along with the image signals or other corresponding signals so as to keep the current knife depth and achieve the purpose of continuously and perfectly cutting the cable insulation skin.

Certainly, in actual operation, the core detecting sensor 52i may be a conventional photoelectric sensor similar to a camera sensor, or may also adopt conventional detecting means such as discharge detection or electromagnetic field induction, and such means, or even the signal transmission and receiving and sending modes thereof, are conventional operation modes in the electronic sensing field, and are not described herein again.

Secondly, a feed angle adjusting component:

for the feed angle adjusting assembly, the structure thereof is shown with reference to fig. 1 to 5 and 11 to 16. 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 mating plate 56h, and the surface of the mating plate 56h is perpendicular to the surface of the adjustment handle 56 c. In the structure shown in fig. 11-16, 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 the 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. 11-12 and 15, the cutting head 56b has a substantially cylindrical configuration with a downward slope. 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 also helps to achieve the best lateral chip guiding and chip discharging effect, and the optimal cutting purpose of the insulating skin can be achieved by matching the cutting angle adjustment 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:

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 section 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 57, and the rear screw slider 50a is fitted to the vertical guide rail 57 through a guide rail corresponding to the vertical slider 57 a.

In actual use, the opening and closing of the peeling clamp 50, that is, the opening and closing of the upper clamp seat 52 relative to the lower clamp, can be controlled by detecting current. For example: when the open-close driving motor 55 rotates, the upper clamp seat 52 and the lower clamp seat 53 are driven to synchronously move towards each other. When the upper and lower jig holders 52 and 53 start to feel the obstruction of the cable insulation sheath, the current of the opening and closing drive motor 55 changes. When the current change of the opening and closing driving motor 55 reaches a set current value, the opening and closing driving motor 55 stops moving, and the peeling clamp 50 can embrace the cable. Through the induction structure, the automatic peeler can clamp cables with different diameters within the range of 70mm-240mm, and realizes a stable peeling function.

On one hand, the blind hole 53b is directly formed in the groove cavity of the V-shaped holding plate 52q, that is, the V-shaped holding surface, so that the purpose of effectively accommodating the guide knife 53c with a certain thickness can be achieved, and the guide knife 53c does not influence the axial movement of the cable. On the other hand, although the guide blade 53c is recessed in the blind hole 53b, the tooth-shaped guide rib 53d may protrude from the cavity surface of the V-shaped holding plate, so that the cutting function of the cable insulation sheath can be performed by the edge of the tooth-shaped guide rib 53 d. In actual practice, as shown in fig. 17-18, the present invention can employ the first adjusting screw 53e to cooperate with the first through counter bore 53g to form the positioning shaft, and the second adjusting screw 53f to cooperate with the second through counter bore 53h to ensure the fixing function of the guiding knife 53c after adjustment. 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.

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, the spiral strip-shaped cut insulation is directly guided to the actual working range of the automatic stripper by the skin guiding device 52w shown in fig. 1-3, and then naturally falls under the action of gravity, so as to avoid hard interference of the hard insulation with the normal action of the automatic stripper as the cutting process progresses.

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 be shown in fig. 2-3 and 5 as a C-shaped sheet with the bow facing upward, when in use, one end is fixed in the groove at the notch of the V-shaped holding plate 52q shown in fig. 5, and the other end can be pressed to generate an elastic pressing action along the groove direction of the groove, and the equipotential elastic sheet returns to 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.

For further understanding the utility model discloses, give here the utility model discloses the specific work flow of the automatic barker who uses as follows:

cable cohesion flow:

when the cable needs to be stripped, the cable to be stripped is firstly clamped between the two groups of V-shaped holding plates 52q of the stripping clamp 50 along the opening of the stripping clamp 50 in the radial direction. 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 thread 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 oppositely hold the cable. When the upper and lower jig holders 52 and 53 start to feel the obstruction of the cable, the current of the opening and closing drive motor 55 changes; when the current change of the opening and closing drive motor 55 reaches a set current value, the opening and closing drive motor 55 stops moving, and the cable is stably held by the peeling jig 50.

Cable peeling process:

before the cable cohesion process is carried out, an operator can judge the thickness of the cable insulation sheath and the cutting angle of the cable according to the model of the current cable, so that the cutting angle of the cutter 56 can be adjusted in advance and adaptively through the cutting angle adjusting assembly. Similarly, the angle of the tooth-shaped guide rib 53d at the guide blade 53c is also adjusted accordingly for the purpose of controlling the axial traveling speed of the cable.

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 automatic peeler is particularly applied to the automatic peeler, 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 starts to operate, so as to drive the rotating sleeve 52g to operate, and 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 tip of the knife 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 blade depth adjusting sliding block 52b are pressed into an integral structure by the radial protrusion 52l of the blade depth adjusting bolt 52f, the cutter 56 at the blade 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 knife depth adjusting knob 52h is rotated to drive the knife 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, the blade depth adjusting slider 52b integrated with the reference positioning plate 52o moves downward by the elastic restoring force of the compression spring, and the zero reference sliding plate 52a equipped with the zero reference bearing maintains the original position by the guide rail fitting relation with the blade depth adjusting slider 52b and the top support 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 rotating sleeve 52g and the limiting protrusion 52n at the position of the knife depth adjusting screw, and the elastic force accumulation action of the compression spring exists, the knife depth adjusting knob 52h can rotate once to a certain position, and then the knife 56 at the position of the knife depth adjusting slider slowly cuts into the cable insulation skin by means of the force releasing performance of the compression spring until the specified cutting depth is reached, which is specifically shown in fig. 10.

In the above steps, once the knife tip of the knife tool 56 just extends into the state of completely stripping the cable insulation sheath and begins to expose the wire core, the wire core detection sensor 52i collects the image signal or other corresponding signals of the wire core at the first time and transmits the signals to the control end, and the knife depth adjusting knob 52h can be stopped at the moment so as to keep the current knife depth. And then, the automatic stripper is operated to act along the axial direction of the cable, so that the aim of continuously stripping the insulating sheath of a certain section of the cable with high efficiency can be fulfilled.
