Description

Technical Field

[0001] This application relates to the field of shoemaking auxiliary tools, and more particularly to a shoe sole positioning fixture. Background Technology

[0002] In fully automated footwear production, sole positioning is a core process for ensuring the quality and yield of finished shoes. This mainly focuses on two stages: sole forming and post-processing, and sole-upper assembly. In the sole forming and post-processing stage, the rough sole blank needs to be placed in a positioning fixture for a series of processes such as edge grinding, trimming, and chamfering to ensure uniform edge dimensions and a neat appearance. Secondly, the sole also needs to undergo grinding, polishing, and adhesive application within the positioning fixture to ensure a secure bond with the upper.

[0003] It is known that due to the different shapes and sizes of various footwear products, and the varying dimensions of different sizes within the same product category, multiple positioning jigs of different specifications are required to handle the positioning processing of different footwear products. However, in the fully automated production process of footwear products, the positioning jigs used in assembly line production are usually multiple sets, resulting in high equipment costs. If multiple different positioning jigs were to be equipped for each different size of footwear product, it would lead to a sharp increase in equipment costs, and a significant amount of time would be required to change positioning jigs when switching product types, which does not meet actual production requirements. Therefore, how to design a positioning jig that can adapt to the positioning of different types and sizes of footwear products has become an urgent problem to be solved. Summary of the Invention

[0004] In order to accommodate the positioning of footwear products of different types and sizes, this application provides a sole positioning fixture.

[0005] The shoe sole positioning fixture provided in this application adopts the following technical solution:

[0006] A shoe sole positioning fixture includes a fixture base, a suspension plate fixedly mounted on the fixture base, and a work station plate fixedly installed on the suspension plate. The work station plate is densely arranged with multiple insertion interfaces, and each insertion interface is correspondingly provided with a set of movable mechanisms. The movable mechanisms can achieve positioning and hold in an initial position and a locked position, and can be switched from the initial position to the locked position by pressing.

[0007] The movable mechanism includes a cylindrical component installed at the insertion interface, a limiting post movably inserted into the cylindrical component, and a steel rod fixedly connected to the workstation plate. The cylindrical component has a vertical groove, and the limiting post has a pin. The pin passes through the vertical groove and slides freely within the vertical groove.

[0008] The outer periphery of the steel rod is provided with two outer end plates, which are spaced apart; the side of the outer end plate near the other outer end plate is provided with multiple limit seats. When the moving mechanism is in the initial position or the locked position, the pin can cooperate with the corresponding limit seat to engage and limit the movement.

[0009] The suspension plate is vertically slidably equipped with a sliding frame plate, and a driving mechanism is provided between the sliding frame plate and the suspension plate to drive the sliding frame plate to slide vertically; multiple sets of anti-reverse mechanisms are closely arranged around the sliding frame plate, and in use, the anti-reverse mechanisms can abut against the outer wall of the shoe sole blank.

[0010] By adopting the above technical solution, this application sets up multiple sets of moving mechanisms. In the initial state, each set of moving mechanisms is in the initial position. At this time, the operator places the shoe sole blank or shoe sole model to be processed inside the sliding frame plate and centers the shoe sole blank or shoe sole model. Then, the shoe sole blank or shoe sole model is forced to move downward, which can switch the corresponding set of moving mechanisms to the locked position. At this time, all moving mechanisms can form a receiving space for accommodating the shoe sole blank, so as to adapt to the positioning and placement of footwear products of different types and sizes and meet the needs of automated production.

[0011] Specifically, the sliding engagement of the pin and the vertical groove allows the limiting post to slide within the cylindrical component. When the movable mechanism is in its initial position, the pin engages with the upper limiting seat, keeping the limiting post extended for pressing. When the limiting post is subjected to downward force, the pin disengages from the upper limiting seat and moves downward, eventually engaging with the lower limiting seat, keeping the limiting post inside the cylindrical component. Based on this, the limiting posts of all movable mechanisms can collectively enclose a space for placing the shoe sole blank. It is known that when the shoe sole blank is placed inside the space, the force exerted on the limiting post in its initial position by the shoe sole blank is a horizontal force, and the position of the movable mechanism will not easily change, facilitating the normal use of the shoe sole positioning fixture.

[0012] In addition, by forcing each set of anti-reverse mechanisms to move closer to the shoe sole blank and making the anti-reverse mechanisms abut against the outer wall of the shoe sole blank, the side wall of the shoe sole blank can be stably supported during the shoe sole processing, so as to facilitate the smooth progress of each processing step.

[0013] Optionally, the limiting seat includes a connecting section integrally formed on the outer end plate and a rigid engaging section integrally formed on the connecting section. The rigid engaging section has an engaging cavity adapted to the pin, and a latching area is provided on the side of the rigid engaging section away from the connecting section. The width of the latching area is smaller than the inner diameter of the engaging cavity.

[0014] By adopting the above technical solution, the limiting seat is made of rigid material. During the process of the pin entering the engagement cavity through the locking area and during the process of the pin disengaging from the rigid engagement section through the locking area, a large force is required. This is beneficial for the moving mechanism to maintain the state in the initial position and the locked position, so as to facilitate the normal use of the shoe sole positioning fixture.

[0015] Optionally, the limiting post is provided with a radially through shaft hole, and the pin is movably inserted into the shaft hole; the end of the pin is provided with an integrally formed anti-disengagement part, and an anti-disengagement disc is detachably installed on the inner side of the limiting post. In use, the anti-disengagement disc abuts against the anti-disengagement part and forces the pin to be partially exposed in the vertical slide groove, so as to realize the engagement of the pin and the limiting seat.

[0016] By adopting the above technical solution, during the installation of the movable mechanism, the column tube component is first inserted into the insertion interface from above the workstation plate, and then the limiting post is inserted into the inner side of the column tube component from below the workstation plate. Next, the operator inserts the pin into the shaft hole and installs the anti-detachment disc inside the limiting post. The outer circumference of the anti-detachment disc abuts against the anti-detachment part of the pin, forcing the pin to move outward to its limit position. At this point, the end of the pin protrudes from the vertical groove, allowing it to engage with the limiting seat and maintain connection between the column tube component and the limiting post. Furthermore, the separate design of the column tube component, limiting post, and pin facilitates the assembly of the movable mechanism and allows for convenient repair and replacement of parts in case of malfunction.

[0017] Optionally, the fixture base is provided with an unlocking module for forcing each set of moving mechanisms to quickly reset. The unlocking module includes a lifting platform that is vertically slidably disposed on the fixture base and an operating mechanism for driving the lifting platform to rise and fall. The lifting platform has multiple limiting holes on its surface, and the bottom of the column member has an insertion part that is inserted into and adapted to the limiting holes. The outer periphery of the insertion part is covered with a rubber sleeve, which cooperates with the limiting holes to limit the movement, so as to realize the detachable connection between the column member and the lifting platform.

[0018] By adopting the above technical solution, the column cylinder is elastically engaged with the lifting platform through the rubber sleeve at the bottom. In use, the lifting platform remains stably positioned, so the column cylinder can also remain against the workstation plate. After a batch of footwear products is processed, the operator can control the operating mechanism to force the lifting platform to move upward. At this time, the column cylinders of each set of moving mechanisms can move together with the limit pins, forcing all the pins to disengage from the lower limit seats. When the lifting platform moves upward to abut against each steel rod, all the pins can engage with the upper limit seats, thereby realizing the rapid reset of each set of moving mechanisms, so as to facilitate the production of the next batch of footwear products.

[0019] Optionally, the operating mechanism includes a push plate that is slidably mounted on the fixture base and several eccentric rods that are rotatably connected to the push plate. The end of the eccentric rod away from the push plate is rotatably connected to the lifting platform, and the eccentric rod is always in an inclined state. The fixture base is provided with a retaining mechanism for positioning the push plate. In use, the push plate and the retaining mechanism cooperate to position the push plate, and the lifting platform can be held at the extreme position of downward movement.

[0020] By adopting the above technical solution, under normal conditions, the push plate needs to cooperate with the retaining mechanism to ensure that the column cylinder of each group of moving mechanisms remains against the work station plate; when it is necessary to quickly reset each group of moving mechanisms, by releasing the limit lock of the retaining mechanism, the operator can push the push plate to move it closer to the lifting platform. The tilted swing rod can gradually move the lifting platform upward, so that all the pins are engaged with the corresponding limit card above.

[0021] Optionally, the retaining mechanism includes a flip plate rotatably mounted on the fixture base and a reset component disposed between the flip plate and the fixture base. The flip plate has an abutment portion and a stop portion. The reset component is used to force the abutment portion to normally abut against the fixture base, at which time the stop portion partially protrudes from the upper surface of the fixture base. In the use state, the push plate abuts against the side of the stop portion away from the lifting platform.

[0022] By adopting the above technical solution, the flip plate can make the abutment part normally abut against the jig base under the elastic force of the reset component. At this time, the push plate can abut against the side of the baffle part away from the lifting platform, and the lifting platform is in the extreme position of downward movement. When it is necessary to quickly reset each group of moving mechanisms, the baffle part is rotated downward by applying force to the flip plate, and the baffle part can smoothly leave the movement path of the push plate part, thereby releasing the limit lock on the push plate base.

[0023] Optionally, the sliding frame plate is provided with multiple connecting holes, each connecting hole corresponding to a set of anti-reverse mechanisms; the anti-reverse mechanism includes a fixed sleeve fixed to the outer side of the sliding frame plate and a side stop post movably disposed inside the fixed sleeve, wherein the fixed sleeve is provided with an axially penetrating movable groove, and the inner bottom wall of the movable groove is provided with an integrally formed first rack portion; the bottom surface of the side stop post is provided with an integrally formed second rack portion, and an elastic component is provided between the side stop post and the fixed sleeve, the elastic component being used to force the first rack portion and the second rack portion to mesh with each other, so as to restrict the movement of the side stop post along its own axial direction.

[0024] By adopting the above technical solution, after the shoe sole blank is placed in the receiving space, the side stop post is moved to abut against the outer wall of the shoe sole blank. Under the elastic force of the elastic component, the side stop post can keep the first toothed part and the second toothed part interlocking with each other, thereby realizing the positioning and holding between the side stop post and the fixed sleeve, and can provide stable support for the side wall of the shoe sole blank during the processing of footwear products.

[0025] Optionally, the first rack portion includes a plurality of first teeth spaced apart. Each first tooth has an inclined guide surface and a straight stop surface. The straight stop surface is located on the side of the first tooth near the sliding frame plate, and the inclined guide surface is located on the side of the first tooth away from the sliding frame plate.

[0026] By adopting the above technical solution, by positioning the inclined guide surface on the side of the first tooth away from the sliding frame plate, after the shoe sole blank is placed in the receiving space, the side stop post can be moved towards the shoe sole blank by directly pushing it inward. In addition, by positioning the straight stop surface on the side of the first tooth near the sliding frame plate, the side stop post is always under force and has a tendency to move outward during the grinding, polishing and gluing operations of the shoe sole blank. At this time, the outward movement of the side stop post can be restricted by the straight stop surface, so as to provide stable support for the sidewall of the shoe sole blank.

[0027] Optionally, the drive mechanism includes a transmission rod, a linkage seat, and a control lever. The transmission rod is rotatably mounted on the suspension plate, and the bottom end of the transmission rod has a threaded section. The linkage seat is threadedly connected to the threaded section. The side of the linkage seat is provided with a linkage groove, and the side of the sliding frame plate is provided with an integrally formed extension platform. The extension platform is partially located in the linkage groove to realize the lifting linkage between the sliding frame plate and the linkage seat.

[0028] The jig base is fixed with a side plate seat, and the control lever is rotatably connected to the side plate seat; the control lever and the transmission rod are driven by a gear pair, and the end of the control lever away from the gear pair is provided with a truncated circular section to force the control lever to rotate.

[0029] By adopting the above technical solution, the truncated circular section of the control lever can cooperate with external auxiliary tools, allowing the operator to force the control lever to rotate using the auxiliary tools. When the control lever rotates, the transmission connection between the gear pairs can drive the transmission rod to rotate. When the transmission rod rotates, the threaded connection between the threaded section and the linkage seat can drive the linkage seat to rise and fall, thereby causing the sliding frame plate to move in the vertical direction. This can adjust the height of each set of anti-reverse mechanisms to adapt to the sidewall support of shoe sole blanks of different thicknesses, thus improving the applicability of the shoe sole positioning fixture.

[0030] In summary, this application includes at least one of the following beneficial technical effects:

[0031] 1. This application achieves this by switching each set of moving mechanisms from the initial position to the locked position, so that all moving mechanisms can form a receiving space for accommodating the shoe sole blank, in order to adapt to the positioning and placement of footwear products of different types and sizes, and to meet the needs of automated production.

[0032] 2. This application sets up multiple anti-reverse mechanisms, which can abut against the outer wall of the shoe sole blank during use, thereby providing stable support for the side wall of the shoe sole blank during the shoe sole processing, so as to facilitate the smooth progress of each processing step; the height of the anti-reverse mechanism can be adjusted with the sliding frame plate, which can adapt to the side wall support of shoe sole blanks of different thicknesses.

[0033] 3. By setting up an unlocking module, after a batch of footwear products is processed, the operator controls the operating mechanism to force the lifting platform to move upward, so that all the pins can engage with the corresponding limit seats above, thereby enabling the rapid reset of each group of moving mechanisms to facilitate the production of the next batch of footwear products.

[0050] The following is in conjunction with the appendix Figure 1 - Appendix Figure 13 This application will be described in further detail.

[0051] This application discloses a shoe sole positioning fixture.

[0052] Reference Figure 1A shoe sole positioning fixture includes a fixture base 1, with multiple support columns 11 fixed to the top surface of the fixture base 1. Each support column 11 is located at one of the four corners of the fixture base 1. A suspension plate 2 is connected to the top of all the support columns 11, thus fixing the suspension plate 2 to the fixture base 1. (See also...) Figure 2 In this embodiment, the suspension plate 2 has a structural groove 21 in the middle, and a work station plate 3 is fixedly installed on the top surface of the suspension plate 2, with the work station plate 3 located directly above the structural groove 21.

[0053] Reference Figure 1 , Figure 2 The workstation plate 3 is densely equipped with multiple insertion ports 31, each of which extends through the upper and lower sides of the workstation plate 3, and each insertion port 31 is correspondingly provided with a set of movable mechanisms 4; in addition, the fixture base 1 is provided with an unlocking module for forcing each set of movable mechanisms 4 to quickly reset. See details below. Figure 2 In this embodiment, the unlocking module includes a lifting platform 5. The top surface of the fixture base 1 is provided with a guide post 12. The lifting platform 5 is provided with a guide groove 52 for the guide post 12 to pass through. The lifting platform 5 can move and rise vertically through the cooperation of the guide post 12 and the guide groove 52. It should be noted that the top surface of the fixture base 1 is provided with a receiving area 13. The receiving area 13 is a blind groove. When the lifting platform 5 moves downward to the limit position, it can abut against the inner bottom surface of the receiving area 13.

[0054] Reference Figure 3 The movable mechanism 4 includes a cylindrical member 41, a limiting post 42, and a steel rod 43. The external dimensions of the cylindrical member 41 are equal to the internal dimensions of the insertion interface 31, so that the cylindrical member 41 can be movably inserted into the insertion interface 31. The top end of the cylindrical member 41 is provided with an outwardly extending annular protrusion 411. The external dimensions of the annular protrusion 411 are larger than the external dimensions of the cylindrical member 41, so that it can cooperate with the insertion interface 31 to limit and prevent the cylindrical member 41 from disengaging from the insertion interface 31.

[0055] Reference Figure 4 The bottom end of the cylindrical member 41 is provided with an integrally formed insert portion 412. The outer diameter of the insert portion 412 is smaller than the outer diameter of the cylindrical member 41, so that a stepped surface can be formed between the cylindrical member 41 and the insert portion 412; a rubber sleeve 413 is fixedly fitted on the outer periphery of the insert portion 412. (See also...) Figure 3 The surface of the lifting platform 5 is densely provided with multiple limiting holes 51. The number of limiting holes 51 is equal to the number of insertion interfaces 31. Each limiting hole 51 is directly opposite to each insertion interface 31, and the inner diameter of the limiting hole 51 is equal to the inner diameter of the insertion part 412.

[0056] When the column cylinder 41 is inserted into the insertion interface 31 and the annular protrusion 411 of the column cylinder 41 abuts against the work station plate 3, the insertion part 412 can be inserted into the limiting hole 51. At this time, the rubber sleeve 413 can pass through the limiting hole 51 and abut against the inner side of the lifting platform 5, thereby restricting the movement of the column cylinder 41 away from the lifting platform 5, realizing the elastic connection between the column cylinder 41 and the lifting platform 5. At the same time, the direct pulling method can also facilitate the subsequent removal, maintenance and replacement of the column cylinder 41.

[0057] Reference Figure 5 In this embodiment, the cylindrical member 41 has an axially penetrating central hole 414. The limiting post 42 is inserted into the central hole 414 and moves along the axial direction of the central hole 414. The bottom end of the limiting post 42 is hollow, and multiple shaft holes 421 are opened on the inner sidewall of the limiting post 42. Each shaft hole 421 extends along the radial direction of the limiting post 42 to the outer circumferential surface of the limiting post 42, and all shaft holes 421 are equidistantly arranged around the axial direction of the limiting post 42. In this embodiment, the specific number of shaft holes 421 is set to four, and a pin 44 is movably inserted into the inner side of each shaft hole 421; at the same time, refer to Figure 6 The end of the pin 44 is provided with an integrally formed anti-detachment part 441. The anti-detachment part 441 is arranged in a ring shape. When each anti-detachment part 441 abuts against each other, it can form a complete ring shape. At this time, the pin 44 can retract into the inner side of the limiting post 42.

[0058] An anti-detachment disc 45 is detachably connected to the inner side of the limiting post 42. In this embodiment, the anti-detachment disc 45 and the limiting post 42 are connected by a threaded connection. However, in other feasible embodiments, the anti-detachment disc 45 and the limiting post 42 can also be connected by fasteners or pins. The top of the anti-detachment disc 45 has a guide portion 451. When the anti-detachment disc 45 is installed, the guide portion 451 can enter the inner side of the area enclosed by each anti-detachment part 441, and then lock the anti-detachment disc 45 to the limiting post 42. The guide portion 451 can force each pin 44 to move outward. Finally, the anti-detachment disc 45 can force each anti-detachment part 441 to press against the inner wall of the limiting post 42. At this time, the pin 44 can be exposed in the shaft hole 421.

[0059] Vertical grooves 415 are provided at the four corners of the cylindrical member 41. After the anti-detachment disc 45 is locked to the limiting post 42, each pin 44 can enter the inner side of the vertical groove 415 respectively; based on this, the circumferential rotation of the limiting post 42 inside the cylindrical member 41 can be restricted. It should also be noted that after the anti-detachment disc 45 is locked to the limiting post 42, the end of the pin 44 away from the anti-detachment part 441 can be exposed outside the vertical groove 415.

[0060] Reference Figure 7The bottom of the workstation plate 3 is provided with a reinforcing rib platform 32, which can improve the overall structural strength of the workstation plate 3. Each reinforcing rib platform 32 is located in the area between adjacent insertion interfaces 31. The reinforcing rib platform 32 has an inner hole 33, and the steel rod 43 is inserted into the inner hole 33. The steel rod 43 is fixedly connected to the workstation plate 3 by connecting bolts 46. The connecting bolts 46 are locked to the top surface of the workstation plate 3, pass through the reinforcing rib platform 32, and are threadedly connected to the steel rod 43. It should be noted that after the steel rod 43 is fixed to the workstation plate 3, it can be located in the diagonal area between adjacent column cylinder members 41.

[0061] Reference Figure 8 The outer periphery of the steel rod 43 is provided with two outer end plates 431. Each outer end plate 431 is integrally formed with the steel rod 43, and the two outer end plates 431 are spaced apart from each other. Each outer end plate 431 is provided with multiple limiting slots 432 on the side near the other outer end plate 431. In this embodiment, there are four limiting slots 432 on one outer end plate 431, which can respectively cooperate with the four adjacent pins 44 on the periphery to lock and limit the movement.

[0062] Specifically, the limiting bracket 432 is made of rigid material. The limiting bracket 432 includes a connecting section 433 integrally formed on the outer end plate 431 and a rigid engaging section 434 integrally formed on the connecting section 433. The rigid engaging section 434 has an engaging inner cavity 435. The inner diameter of the engaging inner cavity 435 is equal to the outer diameter of the pin 44, so that the two can match and engage for limiting. In addition, a latching area 436 is provided on the side of the rigid engaging section 434 away from the connecting section 433. The latching area 436 is connected to the engaging inner cavity 435, and the width of the latching area 436 is smaller than the inner diameter of the engaging inner cavity 435.

[0063] Simultaneously refer to Figure 7 It should be noted that after the steel rod 43 is fixed to the work station plate 3, the anti-detachment plate 45 is locked inside the limiting post 42, forcing each pin 44 to protrude from the vertical slide groove 415. At this time, the pin 44 can be between the two outer end plates 431. When the pin 44 moves upward along the vertical slide groove 415 to the limit position, the pin 44 can enter the locking area 436 of the upper limiting seat 432, forcing the rigid locking section 434 to deform outward. Finally, the pin 44 can match the locking inner cavity 435 of the upper limiting seat 432. At this time, the limiting post 42 can remain extended from the column tube 41, and the moving mechanism 4 is in the initial position.

[0064] In addition, by applying force to the limiting post 42, the limiting post 42 can disengage the pin 44 from the upper limiting seat 432 after being subjected to force; when the limiting post 42 moves downward and the pin 44 matches and engages with the lower limiting seat 432, the pin 44 abuts against the bottom end of the vertical slide groove 415, while the top end of the limiting post 42 can remain flush with the column cylinder 41 and be in a retracted state. At this time, the movable mechanism 4 is in the locked position.

[0065] When the shoe sole positioning fixture of this application is used, each group of movable mechanisms 4 is initially in the initial position. By comparing with the shoe sole blank to be processed or with the shoe sole model, the movable mechanism 4 at the corresponding position is switched to the locked position. At this time, all movable mechanisms 4 can form a receiving space to accommodate the shoe sole blank, so as to adapt to the positioning of different types and sizes of footwear products and meet the needs of automated production.

[0066] Back Figure 1 The unlocking module also includes an operating mechanism 6 for driving the lifting platform 5 to rise and fall. In this embodiment, there are two sets of operating mechanisms 6, which are respectively located on both sides of the width direction of the lifting platform 5. See details. Figure 9 The operating mechanism 6 includes a push plate 61 and several tilting rods 62. The jig base 1 has a sliding groove 14 on its side, and the push plate 61 is slidably disposed in the sliding groove 14, allowing it to move towards / away from the lifting platform 5. Multiple tilting rods 62 are provided and are equidistantly arranged along the extension direction of the push plate 61. One end of each tilting rod 62 is rotatably connected to the push plate 61, and the other end is rotatably connected to the lifting platform 5. In this embodiment, the tilting rods 62 are always in an inclined state, allowing the operator to smoothly move the lifting platform 5 upward when applying force to the push plate 61.

[0067] The fixture base 1 is provided with a retaining mechanism for positioning the push plate 61. Specifically, the retaining mechanism includes a flip plate 15 and a reset component (not shown in the figure); see reference Figure 10 The side of the flip plate 15 is provided with an abutment portion 151 and a baffle portion 152, both of which are integrally formed with the flip plate 15. The flip plate 15 is rotatably mounted on the fixture base 1 via a connecting shaft 153, and the reset component is disposed between the flip plate 15 and the fixture base 1, which can always generate an elastic reset force acting on the flip plate 15, forcing the abutment portion 151 of the flip plate 15 to normally abut against the bottom surface of the fixture base 1. The reset component mentioned here can be a torsion spring or spring, which is a conventional design in the field and will not be described in detail here.

[0068] Back Figure 9The sliding slot 14 has an opening area 16 on its inner bottom surface, and the baffle part 152 is always located inside the opening area 16. When the abutment part abuts against the fixture base 1, the top of the baffle part 152 will partially protrude from the upper surface of the fixture base 1, so that the baffle part 152 is on the moving path of the push plate 61. It should be noted that when the lifting platform 5 moves downward to the limit position abutting against the inner bottom surface of the receiving area 13, the push plate 61 can abut against the side of the baffle part 152 away from the lifting platform 5. At this time, the movement of the push plate 61 is restricted, which can keep the lifting platform 5 in its position.

[0069] Reference Figures 7-9 After a batch of footwear products is produced, force is applied to the flip plate 15, causing the baffle 152 of the flip plate 15 to rotate downwards. Eventually, the baffle 152 can leave the moving path of the push plate 61. The operator can push the push plate 61 to move it closer to the lifting platform 5, which in turn can drive the lifting platform 5, each column cylinder 41 and each limiting column 42 to move upwards. During this process, each pin 44 that is engaged with the lower limiting card 432 can disengage from the corresponding limiting card 432. After moving upwards to the limit position, each pin 44 can engage with the upper limiting card 432 to limit the movement, thereby quickly switching all the moving mechanisms 4 back to the initial position to facilitate the production of the next batch of footwear products.

[0070] In addition, return Figure 2 A sliding frame plate 7 is provided inside the construction groove 21. The external dimensions of the sliding frame plate 7 are equal to the internal dimensions of the construction groove 21, so that the sliding frame plate 7 is movably disposed in the construction groove 21 and can slide vertically within the construction groove 21; at the same time, refer to Figure 1 In this embodiment, the sliding frame plate 7 is always located above the work station plate 3. Multiple sets of anti-reverse mechanisms 8 are arranged at equal intervals around the sliding frame plate 7. In the use state, that is, when the shoe sole blank is placed on the shoe sole positioning fixture for processing, each set of anti-reverse mechanisms 8 can abut against the outer wall of the shoe sole blank, thereby providing stable support for the shoe sole wall.

[0071] Reference Figure 11 The sliding frame plate 7 is provided with a plurality of connecting holes 71 at equal intervals around its perimeter. Each connecting hole 71 is respectively provided with a corresponding anti-reverse mechanism 8. The anti-reverse mechanism 8 includes a fixed sleeve 81 fixed to the outer side of the sliding frame plate 7 and a side stop post 82 movably disposed inside the fixed sleeve 81. The fixed sleeve 81 is provided with an axially penetrating movable groove 811. The inner bottom wall of the movable groove 811 is provided with an integrally formed first rack portion 812. The bottom surface of the side stop post 82 is provided with an integrally formed second rack portion 821. The second rack portion 821 and the first rack portion 812 can mesh with each other, thereby restricting the movement of the side stop post 82 along its own axial direction.

[0072] Simultaneously refer to Figure 12 Taking the first rack portion 812 as an example, the first rack portion 812 includes a plurality of first teeth 813 arranged at equal intervals. Each first tooth 813 has an inclined guide surface 814 and a straight stop surface 815. The straight stop surface 815 is located on the side of the first tooth 813 near the sliding frame plate 7, while the inclined guide surface 814 is located on the side of the first tooth 813 away from the sliding frame plate 7. An elastic component 83 is provided between the side stop post 82 and the fixed sleeve 81. The elastic component 83 can always generate an elastic force acting on the side stop post 82, thereby forcing the side stop post 82 to move downward normally, so that the first rack portion 812 and the second rack portion 821 remain engaged with each other.

[0073] Based on this, after the shoe sole blank is placed in the receiving space, pushing the side support column 82 inward will move the side support column 82 towards the shoe sole blank. During the grinding, polishing and gluing of the shoe sole blank, the side support column 82 is always under force and has a tendency to move outward. At this time, the outward movement of the side support column 82 can be restricted by the straight support surface 815, so as to provide stable support for the side wall of the shoe sole blank.

[0074] Reference Figure 12 In this embodiment, the elastic component 83 includes a spring seat 831, a pusher 832, and a compression spring 833. The spring seat 831 is fixed to the fixed sleeve 81, and the top of the fixed sleeve 81 is provided with a slot, so that the spring seat 831 can be directly opposite the slot. The pusher 832 is movably installed on the spring seat 831, and the pusher 832 is directly opposite the slot. The compression spring 833 is disposed between the pusher 832 and the spring seat 831. The compression spring 833 can always generate an elastic force acting on the pusher 832, so that the pusher 832 can pass through the slot and press against the side stop post 82, thereby forcing the first rack portion 812 and the second rack portion 821 to maintain a meshing state.

[0075] Reference Figure 13 A drive mechanism 9 is provided between the sliding frame plate 7 and the suspension plate 2 to drive the sliding frame plate 7 to slide vertically. Specifically, the drive mechanism 9 includes a transmission rod 91, a linkage seat 92, and a control lever 93. The transmission rod 91 is rotatably mounted on the suspension plate 2, and the bottom end of the transmission rod 91 is provided with a threaded section 911. The linkage seat 92 is threadedly connected to the threaded section 911. The side of the linkage seat 92 is provided with a linkage groove 921, and the side of the sliding frame plate 7 is provided with an integrally formed extension platform 72. The extension platform 72 is located at the bottom edge of the sliding frame plate 7, and the extension platform 72 is partially located in the linkage groove 921, so that the sliding frame plate 7 can move together with the linkage seat 92.

[0076] A side plate seat 17 is fixed to the side of the fixture base 1, and the operating lever 93 is rotatably connected to the side plate seat 17. A gear pair 94 is provided between the operating lever 93 and the transmission rod 91. The gear pair 94 enables the transmission connection between the operating lever 93 and the transmission rod 91, that is, the rotation of the operating lever 93 can drive the transmission rod 91 to rotate. It should be noted that the gear pair 94 in this embodiment uses two bevel gears, but in other feasible embodiments, the transmission pair can also be a spur gear or a helical gear, which is not the case here.

[0077] The end of the control lever 93 furthest from the gear pair 94 is provided with a truncated circular section 931. The truncated circular section 931 is obtained by machining grooves on both sides of the control lever 93, which can cooperate with external auxiliary tools to smoothly control the rotation of the control lever 93. When the control lever 93 rotates, it can drive the transmission rod 91 to rotate. Then, the threaded connection between the threaded section 911 and the linkage seat 92 can make the linkage seat 92 rise and fall vertically, thereby moving the sliding frame plate 7 in the vertical direction. This can adjust the height of each set of anti-reverse mechanisms 8 to adapt to the side wall support of shoe sole blanks of different thicknesses, thus improving the applicability of the shoe sole positioning fixture.

[0078] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
