Detailed Description
Referring to fig. 1 to 24, a first embodiment of the present invention includes a traction mechanism 100, a turnover mechanism 200, and a positioning mechanism 300.
The traction mechanism 100 is provided with a first active state, a second active state and a static state, the traction mechanism 100 and the turnover mechanism 200 are separated and linked in the first active state, the traction mechanism 100 and the turnover mechanism 200 are separated and relatively move in the second active state, and the traction mechanism 100 and the turnover mechanism 200 are attached and limited in the static state.
The first active state, the second active state and the static state respectively express three matching processes, in which the traction mechanism 100 and the turnover mechanism 200 have a mutual matching relationship, which is:
when the traction mechanism 100 and the turnover mechanism 200 are in the first active state, the corresponding matching parts belonging to the traction mechanism 100 and the turnover mechanism 200 are separated in space, but a part capable of enabling the traction mechanism 100 and the turnover mechanism 200 to be linked with each other still exists between the traction mechanism 100 and the turnover mechanism, and particularly, the relevant part of the traction mechanism 100 drives the corresponding part of the turnover mechanism 200;
when traction mechanism 100 and turnover mechanism 200 are in the second active state, the corresponding mating components belonging to both are still spatially separated, but different from the first active state, they are in relative motion, i.e. one of them is stationary and the other is moving relative to it, specifically, the relevant components of traction mechanism 100 are moving and turnover mechanism 200 is stationary;
when traction mechanism 100 and turnover mechanism 200 are in a static state, the corresponding mating components belonging to both are fitted together, and just as the two are fitted together, they are mutually limited and static.
The first active state has a first active path a, which is a straight line. The first activity state is a motion process of the traction mechanism 100, and the first activity path a is a virtual technical term, and therefore is expressed by a dotted line in the drawing, which is an activity law that the traction mechanism 100 should follow, meaning that the traction mechanism 100 has a preset law of linear motion along the first activity path a, and the linear first activity path a is relatively simple in structure and easy to assemble and maintain.
The second active state has a second active path b, which is a straight line. The first active state is also the motion process of the traction mechanism 100, and the second active path b is also a virtual technical term, and therefore is expressed by a dotted line in the drawing, which is the active rule that the traction mechanism 100 should follow, meaning that the traction mechanism 100 has a preset rule of moving linearly along the second active path b, and the linear second active path b has a relatively simple structure and is easy to assemble and maintain.
The first moving path a or the second moving path b is not limited to a straight line, and in fact, to implement three matching configurations of the traction mechanism 100 and the turnover mechanism 200, the structure of the traction mechanism 100 is infinite, for example, the moving path matching with the structure may be a perfect circle, or the first moving path a is a straight line, and the second moving path b is a non-straight line, although the first moving path a and the second moving path b are relatively complex if they are shaped differently, so that the body becomes larger and occupies more space.
The first active state has a first active path a, the second active state has a second active path b, and the first active path a and the second active path b are reversely assembled. The reverse assembly herein means that the first active movement direction of the traction mechanism 100 and the second active movement direction of the traction mechanism 100 are opposite, and does not mean that the first active path a and the second active path b are opposite in shape, for example, in the case of the aforementioned straight line or perfect circle, the reverse setting can make the structure compact and the performance stable without the forward or reverse direction.
The second active state, the static state and the first active state are switched in sequence. This means that the transition from the second active state to the first active state is performed through the coordination process of the static state, rather than directly switching between the first active state and the second active state by ignoring the static state, but it is also only for the situation under normal operation that a fault condition and a debugging stage need to be eliminated, and the two states are manually intervened and can be mutually converted without passing through the static state, which has the advantage of bringing about the effects of compact structure, stable performance and reliability.
The turnover mechanism 200 has a rotation shaft 201, the rotation shaft 201 has a shaft axis c, the shaft axis c is a straight line, and the rotation shaft 201 is turned over around the shaft axis c. The rotating shaft 201 is used as a component which is acted by the traction mechanism 100 to realize the overturning function, and the manufacture and the processing are easy. Flipping may also be referred to as slewing or rotating. The shaft 201 is a key component of the turnover mechanism 200, and one of the purposes of the traction mechanism 100 is to drive the turnover mechanism. The axis c is a center line of the rotating shaft 201, and it is specifically described that the lower case letters in the drawings in the description of the present invention, such as a, b, c, etc., are all virtual technical terms, and also in a geometric sense, a slight deviation may occur in an actual product during assembly operation due to a precision, etc., but the deviation cannot be considered to cause the deviation to depart from the protection scope of the present invention, and the protection scope of the present invention should be considered to include a meaning that can be covered by the claims of the present invention.
The rotating shaft 201 is provided with a rotating shaft limiting portion 203 and a rotating shaft following portion 204, the traction mechanism 100 is separated from the rotating shaft limiting portion 203 in a first active state, the traction mechanism 100 is linked with the rotating shaft following portion 204 in the first active state, the traction mechanism 100 is separated from the rotating shaft limiting portion 203 in a second active state, the traction mechanism 100 is relatively moved with the rotating shaft following portion 204 in the second active state, the traction mechanism 100 is attached to the rotating shaft limiting portion 203 in a static state, and the traction mechanism 100 is static with the rotating shaft following portion 204 in the static state. The further refinement structure of the rotating shaft 201 is to divide the rotating shaft 201 into different parts of a rotating shaft limiting part 203 and a rotating shaft following part 204, so that the limiting and following functions have proper practical structures to be realized. The traction mechanism 100 and the rotating shaft limiting part 203 in the first active state and the second active state are separated and do not contact with each other, the traction mechanism 100 and the rotating shaft following part 204 are linked in the first active state, namely, the traction mechanism 100 drives the rotating shaft following part 204 and even the whole rotating shaft 201, the traction mechanism 100 and the rotating shaft following part 204 in the second active state move relatively, namely, the traction mechanism 100 moves independently and the rotating shaft following part 204 is static at the moment, and the rotating shaft 201 is static as the traction mechanism 100 and the rotating shaft limiting part 203 are attached and contacted in the static state.
The rotation shaft limiting portion 203 has a rotation shaft limiting plane 205. The contact area is increased through surface contact, so that the effect of reliable limit can be brought.
The rotation shaft limiting portion 203 has two rotation shaft limiting planes 205, and the two rotation shaft limiting planes 205 are symmetrically arranged with the axis c as the center. The contact area is further increased to improve the static effect during limiting.
For the indexing requirement of the turning of the rotating shaft 201, the rotating shaft limiting planes of the invention are four, are arranged symmetrically in two pairs, and are respectively applied to limiting when the rotating shaft 201 rotates 90 degrees, so that the cross section of the rotating shaft 201 is square at the moment, and similarly, if the invention is applied to indexing occasions of other angles, such as 60 degrees, the rotating shaft is preferably processed into six rotating shaft limiting planes which are arranged symmetrically in three pairs, and the cross section is hexagonal at the moment, and so on.
The traction mechanism 100 is provided with a cylinder body 101, a cylinder piston rod 102, a first traction piece 103, a second traction piece 104 and a push rod 105, the cylinder body 101 and the second traction piece 104 are fixedly assembled, the push rod 105 and the cylinder piston rod 102 are fixedly assembled, the push rod 105 and the first traction piece 103 are fixedly assembled, the cylinder piston rod 102 and the cylinder body 101 are movably assembled relatively, the first traction piece 103 and the second traction piece 104 are respectively provided with a traction limiting part 106, the two traction limiting parts 106 are separated from each other in a first movable state, the two traction limiting parts 106 are folded with each other in a second movable state, and the two traction limiting parts 106 are respectively attached to and limit the turnover mechanism 200 in a static state.
By fixed assembly is meant a fixed relationship to each other during operation after assembly, and more particularly in this section is the relative movable assembly of the cylinder rod 102 and cylinder block 101, which involves two processes: one of them is the original effect of the cylinder rod 102, the cylinder rod 102 reciprocates in the inner cylinder of the cylinder block 101, i.e. the cylinder block 101 is stationary and the cylinder rod 102 moves relative to the cylinder block 101; the other is the overall thrust force on the cylinder block 101 generated by pressurization, which may be generated when the cylinder rod 102 is initially pressurized to move in the inner cylinder of the cylinder block 101, or may be generated by continuing pressurization after the cylinder rod 102 moves to the limit position of the inner cylinder of the cylinder block 101, i.e., the side wall, but in any case, the overall thrust force is necessarily generated in the first active state or the second active state.
The two traction limiting parts 106 are separated from each other in the first active state to show that the linear distance between the two traction limiting parts 106 in the space is increased, whereas the two traction limiting parts 106 are folded together in the second active state to show that the linear distance between the two traction limiting parts 106 in the space is decreased, and the two traction limiting parts 106 can certainly ensure that the overturning mechanism 200 is more reliably limited, although in principle, one traction limiting part 106 can already realize the limitation of the overturning mechanism 200. The traction limiting portion 106 is only used to express that the traction limiting portion 106 or the second traction member 104 is used to contact the turnover mechanism 200, and it is essential that the first traction member 103 and the second traction member 104 are separated from each other or folded together or attached to and limited by the turnover mechanism 200.
The traction limiting part 106 has a rigid pad 107, and the rigid pad 107 and the turnover mechanism 200 are attached and limited in a static state. Specifically, the rigid pad 107 is fixedly connected to the traction limiting portion 106 for contacting the turnover mechanism 200, and the rigid pad 107 is made of wear-resistant and impact-resistant material to ensure the service life thereof.
The traction limiting portion 106 has an elastic pad, and the elastic pad is attached to the turnover mechanism 200 and limits the position in the static state. The soft material is easier to cushion than the rigid material, and certainly has a longer life, but the positioning accuracy is relatively degraded by the deformation deviation, but the deformation is very slight, and if the deformation is a large stroke, the preset deformation amount must be calculated without affecting the positioning accuracy.
The draft stop portion 106 has a draft stop plane 108. When the aforementioned turnover mechanism 200 has the rotation shaft limiting plane 205, the traction limiting plane 108 will form a surface contact with the rotation shaft limiting plane 205, and the limiting effect is stable and reliable.
The traction mechanism 100 comprises a first slide block 109, a second slide block 110 and a line rail 111, wherein the first traction piece 103 is fixedly assembled with the first slide block 109, the second traction piece 104 is fixedly assembled with the second slide block 110, the first slide block 109 is linearly assembled with the line rail 111 in a relative sliding manner, and the second slide block 110 is linearly assembled with the line rail 111 in a relative sliding manner.
The first traction element 103 and the first sliding block 109 may be two separate components or may be an integral component made of the same material, and similarly, the second traction element 104 and the second sliding block 110 are also fixed, and the wire rail 111 is fixed, so that the relative sliding of the first sliding block 109 and the second sliding block 110 is relative to the stationary wire rail 111, and thus the first traction element 103 and the second traction element 104 also slide relative to the stationary wire rail 111, similar to the matching relationship between a train and a rail.
The turnover mechanism 200 is provided with a following chain wheel 206, the traction mechanism 100 is provided with a traction chain 112 and an elastic traction piece 113, the traction chain 112 and the following chain wheel 206 are in meshing assembly, the traction chain 112 and the elastic traction piece 113 are in connection assembly, the elastic traction piece 113 is compensated to act on the traction chain 112 in the first active state, and the elastic traction piece 113 is pre-tensioned to act on the traction chain 112 in the second active state.
The structure described in this paragraph solves the principle technical details of the engagement of the traction mechanism 100 and the turnover mechanism 200, in which the traction mechanism 100 uses the traction chain 112 to drive the follower sprocket 206 to rotate, but the elastic traction element 113 must be added, and since the distance of the traction chain 112 relative to the follower sprocket 206 changes, a compensation element capable of compensating the relative position change is required, and the elastic traction element 113 plays this role through elastic deformation, namely the compensation role in the first active state, and needs to be prepared for the next round of action in advance after the traction chain 112 is reset, and needs to keep the engagement with the follower sprocket 206, so the elastic traction element 113 needs to apply pretension to the traction chain 112 to keep the two tension forces.
The following are two ways of the traction mechanism 100 and its traction chain 112 to cooperate:
in one form, referring primarily to fig. 13, the traction mechanism 100 has a first traction point 114, and the traction chain 112 and the first traction point 114 are fixedly mounted. The first traction point 114 is moved to drive the traction chain 112 and the follower sprocket 206;
the other way is that the traction mechanism 100 is provided with a traction chain wheel 115, a traction chain 112 is engaged with the traction chain wheel 115, the traction chain wheel 115 is rotatably assembled with the first traction element 103, the traction chain 112 is fixedly assembled with the first traction element 103, and the elastic traction element 113 is connected with the second traction element 104. When the first traction element 103 and the second traction element 104 are moved, the traction sprocket 115 can drive the traction chain 112 and thus the follower sprocket 206.
It can be seen that the difference between the first and second modes is in the manner of driving the traction chain 112, the first mode corresponding to a direct pull and the second mode corresponding to an engagement drive, from which many derivatives can be derived: the connection structure of the two ends of the traction chain 112 is not required to be concerned, and one end of the traction chain can be connected with the first traction piece 103, and the other end of the traction chain can be connected with the second traction piece 104; either both ends are connected to the first traction element 103 or both ends are connected to the second traction element 104; the first traction point 114 can come from a myriad of related parts to which it is mounted, such as a round ball, a straight rod, etc., which are denoted by i in fig. 14.
This paragraph, which is still a variation of the previously described derivative structure, can be seen in FIG. 14: the turnover mechanism 200 is provided with a following wheel 207, the traction mechanism 100 is provided with an elastic traction member 113, the elastic traction member 113 and the following wheel 207 are in sliding friction and are elastically stretched in a first active state, and the elastic traction member 113 and the following wheel 207 are in sliding friction and are elastically retracted in a second active state.
The flexible structure described in the previous paragraph is characterized in that the sliding friction fit relationship between the elastic traction member 113 and the follower wheel 207 is that the follower wheel 207 is driven to rotate by the sliding friction provided by the elastic traction member 113, but the elastic traction member 113 simultaneously performs three functions of driving, elastic deformation and pre-tightening, and the elastic deformation function and the pre-tightening function of the flexible structure are referred to above.
The elastic pulling element 113 is in this embodiment in the form of a spring, which is connected at both ends to the pulling chain 112 and the second pulling element 104, respectively, which is a convenient assembly, but it can be mounted at all other positions of the pulling chain 112, even in a connection between two separate pulling chains 112.
Referring to fig. 15, the traction mechanism 100 has a first traction point 114, the first traction point 114 and the shaft axis c have a first traction line segment d, the first traction line segment d and the shaft axis c are vertically assembled, and the first traction line segment d grows in the first active state. The first traction segment d is substantially a perpendicular between the first traction point 114 and the axis c, and increases in the first active state as the first traction point 114 moves away from the rotation axis 201.
The traction mechanism 100 has a second traction point 116, the second traction point 116 and the axis c have a second traction line segment e, the second traction line segment e is vertically assembled with the axis c, and the second traction line segment e is increased in the first active state. The second pulling line segment e is the same as the first pulling line segment d of the upper segment.
The first tow point 114 and the second tow point 116 have a tow line segment f that increases in the first active state. The pulling line segment f is the connecting line between the two points, and the first active state is increased due to the separation of the two points, and correspondingly, the second active state is decreased due to the close of the two points.
The canting mechanism 200 has a follower ring 208, a pawl 209, the pawl 209 having a static state and an active state, the traction mechanism 100 having traction teeth 117, the first active state having the pawl 209 in the static state, the first active state having the pawl 209 and traction teeth 117 in a relatively static state, the second active state having the pawl 209 in the active state, the second active state having the pawl 209 and traction teeth 117 in a relatively active state.
The follower ring 208 is substantially a collar sleeved outside and fixed with the rotating shaft 201, the traction teeth 117 are substantially a gear ring fixed inside the follower sprocket 206, if the follower ring 208 and the traction teeth 117 need to realize linkage, a one-way following effect brought by the pawls 209 is required, the pawls 209 are in a first movable state of the traction mechanism 100 when in a stationary state, at the moment, the pawls 209 are in a stationary state due to the abutment with the traction teeth 117, so that the traction mechanism 100 drives the pawls 209, the follower ring 208 and the rotating shaft 201 integrally through the traction teeth 117, otherwise, the pawls 209 are no longer in the aforementioned abutment position when in a second movable state, and the traction teeth 117 and the pawls 209 are in relative movable fit: either the pulling teeth 117 and the pawl 209 are both moving and have some contact and relationship, colloquially, the pulling teeth 117 slipping relative to the pawl 209, or the pulling teeth 117 moving and the pawl 209 stationary, etc.
The turnover mechanism 200 has an elastic member 210, a pawl 209 and a follower ring 208 are relatively rotatably assembled, and the elastic member 210 is assembled between the follower ring 208 and the pawl 209.
When a spring is used as the elastic member 210, the elastic member 210 always acts on the pawl 209, and the relative rotational assembly of the pawl 209 and the follower ring 208 herein means that the pawl 209 and the follower ring 208 have a relative rotational relationship rather than an absolutely fixed connection, but as mentioned above, the pawl 209 and the follower ring 208 still have a relatively stationary first active state time, and in the second active state, the so-called relative rotational relationship is formed.
When a spring is used as the elastic member 210, the specific structure is: the follower ring 208 is provided with a receiving groove 211, a first rib 212 and a second rib 213, the receiving groove 211 is communicated with the side space of the follower ring 208 so that the detent 209 is laterally fitted into the receiving groove 211, the receiving groove 211 is communicated with the forward external space of the follower ring 208 so that the detent 209 protrudes out of the follower ring 208 under the action of a spring, the detent 209 has a rotating part 214 and an interference part 215, the detent 209 rotates around the geometric central axis of the rotating part 214 thereof,
the pawl 209 is in interference linkage with the traction tooth 117 by the interference part 215, the first rib 212 acts on the rotation limiting part 214 to prevent the pawl 209 from being disengaged from the accommodating groove 211, and the second rib 213 acts on the interference limiting part 215 to prevent the pawl 209 from being protruded out by too large angle.
The positioning mechanism 300 comprises a connecting plate 301, a base block 302 and a locking pin 303, wherein the base block 302 comprises a base block locking cylinder 304, the locking pin 303 is fixedly assembled with the connecting plate 301, the locking pin 303 is movably assembled with the base block 302, the locking pin 303 comprises a locking pin first inclined surface 305, the base block locking cylinder 304 comprises a base block piston rod 306, and the base block piston rod 306 comprises a base block piston rod inclined surface 307. The link plate 301 in the positioning mechanism 300 described in this paragraph is used to directly load a workpiece to be machined, the workpiece to be machined is fixedly connected with the link plate 301, and the lock pin 303 is fixedly connected with the link plate 301, so that the workpiece to be machined, the link plate 301, and the lock pin 303 are assembled into a whole, and the linear feed motion of the base block piston rod 306 is converted into the relative movement of the whole where the lock pin 303 is located with respect to the base block 302 by the abutting engagement of the base block piston rod inclined surface 307 and the lock pin first inclined surface 305, so as to complete the locking and positioning of the workpiece in the base block 302, and the locking in the inclined surface matching manner can have the effects of precise action and reduced wear.
The locking pin 303 has a locking pin first through hole 308 and the locking pin first ramp 305 is located in the locking pin first through hole 308. The lock pin 303 is divided into two parts, one part is used for arranging threads so as to be fixedly assembled with the connecting plate 301 through the threads, the other part is provided with a lock pin first through hole 308, and when the base block piston rod inclined surface 307 is positioned in the lock pin first through hole 308, the two side edges can limit the lock pin at two sides, so that the lock pin can be pushed in or withdrawn out more smoothly.
When the workpiece to be processed is loaded in the positioning mechanism 300, it can also perform an independent turnover, called independent turnover, with respect to the positioning mechanism 300, which is not confused with the turnover of the turnover mechanism 200, that is, the workpiece to be processed has two turnover modes, respectively: one is when tilting mechanism 200 overturns, positioning mechanism 300 with treat the whole upset along with of machined part, and its two is even if tilting mechanism 200 stops when overturning, treats that the machined part also can independently overturn for tilting mechanism 200 and positioning mechanism 300, and both can go on according to the preface certainly, also can go on in step.
The independent overturning can be realized by two types of manual structures and mechanical structures in general:
the manual structure is the third embodiment, the positioning mechanism 300 has a positioning locking cylinder 309, the positioning locking cylinder 309 has a positioning piston rod 310, and the positioning piston rod 310 has a positioning piston rod inclined surface 311.
The structure is additionally provided with a positioning locking cylinder 309 which has the same second action and action principle as the base block locking cylinder 304, but the action directions of the two locking cylinders are different, when any one locking cylinder moves back, the whole of the workpiece to be processed, the connecting plate 301 and the lock pin 303 can be detached from the base block 302, and the workpiece to be processed, the whole of the connecting plate 301 and the lock pin 303 can be loaded in another locking cylinder with different locking directions and locked by the other locking cylinder, but before loading, the fixed angle of the lock pin 303 and the workpiece to be processed relative to the connecting plate 301 needs to be manually adjusted, and finally, the result that the workpiece to be processed is locked again after.
While both lock cylinders of lock pin 303 have been described as engaging lock pin first ramp 305, lock pin 303 may be modified such that lock pin 303 has lock pin second ramp 312. The orientation of the second inclined surface 312 of the lock pin is different from that of the first inclined surface 305 of the lock pin, and the two inclined surfaces correspond to two locking cylinders respectively in order to be aligned and matched with the inclined surface 311 of the positioning piston rod, and the second inclined surface 312 of the lock pin has the advantage that the fixed angle of the lock pin 303 and the workpiece to be machined relative to the connecting plate 301 does not need to be manually adjusted after the workpiece is unloaded from the whole of the connecting plate 301 and the lock pin 303.
The base block piston rod 306 has a first reference straight line g, the positioning piston rod 310 has a second reference straight line h, and the first reference straight line g and the second reference straight line h are vertically assembled. The first reference straight line g and the second reference straight line h are not central lines of two irregular piston rod inclined planes, but are central lines of a cylinder barrel where the first reference straight line g and the second reference straight line h are installed respectively, and are suitable for occasions with two processing stations with vertical adjustment angles.
The lock pin first through hole 308 and the lock pin second through hole 333 are through-fitted. So that the lock pin 303 is compact.
Lock pin first ramp 305 and lock pin second ramp 312 interfit. Both figures of the specification have an intersecting line j. In fact, the lock pin first inclined surface 305 and the lock pin second inclined surface 312, the lock pin first through hole 308 and the lock pin second through hole 333 are completely the same in shape, and the lock pin 303 is more compact in structure and simpler and more attractive in appearance.
The maneuvering structure is the first embodiment and the second embodiment, the positioning mechanism 300 is provided with a positioning cylinder 313, a positioning pin 314 and a positioning gear 315, the positioning cylinder 313 is provided with a piston rod rack 316, the positioning gear 315 and the piston rod rack 316 are assembled in a meshed mode, the positioning pin 314 and the base block 302 are fixedly assembled, and the positioning pin 314 and the positioning gear 315 are fixedly assembled. The piston rod rack 316 is a rack arranged on the periphery of the piston rod of the positioning cylinder 313, and can be directly processed on the piston rod or be fixed on the piston rod in an after-loading manner, and the positioning gear 315, the positioning pin 314 fixed on the positioning gear and the base block 302 are driven to rotate together through the linear motion of the piston rod of the positioning cylinder 313, so that the angle and the direction relative to the turnover mechanism 200 are adjusted.
The base block 302 has a base block first positioning portion 317, and the positioning cylinder 313 has a piston rod positioning portion 318. The two positioning portions are in contact fit, the piston rod positioning portion 318 is substantially a surface for positioning the end of the piston rod in the cylinder 313, and precisely, the piston rod positioning portion 318 moves linearly to push the base block 302, the positioning gear 315 and the positioning pin 314 through the end of the piston rod, but the fit relationship between the two does not occur in the linear action of the positioning cylinder 313 every time, because the main positioning of the base block 302 is completed by means of the aforementioned gear-rack fit, and the interference between the two occurs and brings about the result of auxiliary positioning only when the gear-rack fit has an error or the gear-rack is idle due to abrasion or the like.
In addition, an additional auxiliary positioning structure is also arranged: the positioning mechanism 300 has the auxiliary positioning portion 319, and the base block 302 has the base block second positioning portion 320. It has two effects of preventing inertia, one is that the excessive gyration that the inertia that piston rod rack 316 drove positioning gear 315 brought is prevented, and the other is that the excessive gyration that piston rod location portion 318 drove the inertia of base block first location portion 317 is prevented to play the effect of accurate location.
The auxiliary positioning portion 319 has an auxiliary through hole 321, and the positioning pin 314 and the auxiliary through hole 321 are movably assembled. The auxiliary positioning portion 319 and the auxiliary through hole 321 are substantially different portions of a protrusion, and the protrusion may be disposed on an outer wall of the rotating shaft 201. The positioning gear 315 is located in the middle, two auxiliary through holes 321 are respectively formed on two sides of the positioning gear, and two protruding portions of the base block 302 are outward to be fixedly connected with two ends of the positioning pin shaft 314, so that the volume can be reduced as much as possible while necessary performance is provided.
The positioning mechanism 300 is provided with a sleeve 322, the sleeve 322 is fixedly assembled with the rotating shaft 201, and the sleeve 322 is axially and oppositely assembled with the rotating shaft 201 in a distance adjusting mode. In the third embodiment, when the additional structure of the sleeve 322 is selected, the aforementioned protrusion of the auxiliary positioning portion 319 and the auxiliary through hole 321 can be manufactured integrally with the sleeve 322, but if the sleeve 322 is not provided, the rotating shaft 201 must be configured as a sectional type combination structure as in the second embodiment, otherwise, the assembly of the rotating shaft 201 would be very difficult due to the aforementioned protrusion, and the sleeve 322 easily solves the problem,
the axial relative distance adjustment assembly of the cylinder sleeve 322 and the rotating shaft 201 means that the cylinder sleeve 322 is provided with a through pin hole 323 and an axial front-back position, and the rotating shaft 201 is also provided with a through pin hole 324, so that after the pin is disassembled, the cylinder sleeve 322 can move axially front and back relative to the rotating shaft 201 sleeved with the cylinder sleeve, and after the front-back distance adjustment is completed, the cylinder sleeve 322 and the rotating shaft 201 are fixed and assembled by the pin at the same time, and the adjustment is completed.
It should be noted that the positioning locking cylinder 309 in the manual structure or the positioning cylinder 313 in the motorized structure has different functions, but the installation positions are the same, that is, the positioning locking cylinders are installed at the ends of the rotating shaft 201.
The following combination is applied to shoes die block 900 occasion and presss from both sides the dress as the supporting of engraver and carry out the integrated introduction of theory of operation as, shoes die block 900 need process five its faces, but the cutter is unidirectional when shoes die block 900 processing, consequently need the supporting of engraver to press from both sides the dress and accomplish the rotation in order to process four sides, and the process of a bottom surface of upset processing, certainly also have the multidirectional cutter engraver of higher level but the high-level operating personnel of cost is bought and is required, or the three-dimensional printing technique of immature and high-cost company, consequently it is still comparatively realistic scheme to use the supporting of this engraver to press from both sides the dress and carry out shoes die block 900 processing at present stage:
the shoe bottom mold 900 is generally fixedly connected to the connecting plate 301 through threads, the base block piston rod 306 of the base block locking cylinder 304 is pushed to lock the lock pin 303, the lock pin 303 in the process has a displacement slightly towards the rotating shaft 201, the cylinder block 101 is of a bidirectional type, from the beginning of air inflation, the first traction piece 103 and the second traction piece 104 are linearly close to each other, and the rotating shaft 201 cannot be driven to rotate together due to the fact that the traction teeth 117 slip relative to the pawls 209 until the traction limiting planes 108 on the two sides are respectively attached to the rotating shaft limiting planes 205 on the two sides of the rotating shaft 201, namely, a second movable state is obtained.
The static state is a process that the rotating shaft 201 is static and the cutter processes the shoe bottom mold 900.
The rotation of the rotating shaft 201 can be started when the first traction element 103 and the second traction element 104 are separated from each other, when the first traction element 103 and the second traction element 104 are separated, the traction chain wheel 115 drives the follow-up chain wheel 206 through the traction chain 112, the pawl 209 and the traction tooth 117 at this time completely collide and link, the follow-up chain wheel 206 drives the follow-up ring 208 and the rotating shaft 201 to integrally rotate, the elastic traction element 113 selects a spring which is easy to obtain, and also starts to be stressed and stretched to compensate the difference of the traction chain 112 caused by the separation of the first traction element 103 and the second traction element 104, because four side surfaces of the sole mold 900 are processed, the rotating shaft 201 needs to rotate four times, the angle of each rotation is 90 degrees, of course, the farthest limit distance of the separation of the first traction element 103 and the second traction element 104 from each other is preset, the rotating shaft 201 can be just driven to rotate 90 degrees, and the first movable state is completed after the farthest limit distance is reached, then the two are drawn together again to repeat the second active state.
It should be added that, no matter the manual structure or the motorized structure, the double-station structure is double-station, and the double-station structure can operate simultaneously corresponding to the double knives so as to improve the processing efficiency, so the positioning mechanism 300 is double and is assembled on both sides of the turnover mechanism 200, the drawings in the specification only mark one of the positioning mechanisms 300, the double stations of the second and third embodiments are at different angles only for conveniently displaying the structure, and the double stations are synchronous and symmetrical in actual operation.
The difference between the first, second and third embodiments is that the positioning mechanism 300 and the rotating shaft 201 of the turnover mechanism 200, and the drawings in the description mainly show the interior of the first embodiment, but the traction mechanisms 100 of the three embodiments are all identical, so that reference is made to the interior structure of the first embodiment.
