Detailed Implementation

[0020] The present invention will be described in detail below with reference to specific embodiments.

[0021] In this invention, when directional terms appear, they are used to facilitate the description of the invention and to simplify the description, rather than indicating or implying that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific scope of protection of the invention.

[0022] In this invention, unless otherwise explicitly specified and limited, the terms such as "set in," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can also refer to a mechanical connection; they can refer to a direct connection or a connection through an intermediate medium; or they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0023] like Figures 1 to 3As shown, a shoe last drilling and pressing machine includes a vertical machine base 10, a shoe last placement table 20, a shoe last fixing clamp 30, a first drilling device 40, a sleeve feeding and pressing device 50, and a second drilling device 60.

[0024] The vertical machine 10 includes an L-shaped first box 11 and a second box 12. The shoe last placement table 20 is set on the second box 12 for placing shoe lasts.

[0025] The shoe last fixing claw 30 is mounted on the second housing 12 and located above the shoe last placement platform 20. The second housing 12 is equipped with a drive switch 34 that is connected to the shoe last fixing claw 30 for driving the shoe last fixing claw 30 to clamp and fix the shoe last on both sides of the shoe last placement platform 20.

[0026] The first drilling device 40 is mounted on the first housing 11 and located above the shoe last fixing claw 30, for vertically drilling holes in the upper end of the shoe last. The sleeve feeding and clamping device 50 is mounted on the first housing 11 and located on one side of the shoe last placement platform 20, for feeding the sleeve into the mounting hole on the shoe last and clamping it in place. The second drilling device 60 is mounted on the second housing 12 and located on the other side of the shoe last placement platform 20, for vertically drilling holes in the side of the shoe last.

[0027] In practical implementation, the first housing 11 and the second housing 12 are integrally formed sheet metal housings, allowing the first drilling device 40 and the second drilling device 60 to be distributed in a spatial rectangular coordinate system. This structure not only reduces the equipment's footprint, but more importantly, through a three-dimensional spatial layout, ensures that the movement trajectories of each processing unit do not interfere with each other, effectively guaranteeing safety during simultaneous multi-process operations.

[0028] The shoe last to be processed is placed on the shoe last placement table 20. The shoe last fixing claw 30 is driven by the drive switch 34 to clamp and fix the shoe last on the shoe last placement table 20 to prevent the shoe last from loosening. The first drilling device 40 and the second drilling device 60 are driven by the preset program of the control cabinet to drill holes at the top and side ends of the shoe last. Then, the sleeve feeding and pressing device 50 sends the sleeve into the hole at the top end of the shoe last for pressing and resetting. Finally, the shoe last fixing claw 30 is released by the drive switch 34, and the shoe last that has been drilled and pressed can be taken out and put back into the shoe last to be processed for further processing.

[0029] like Figures 1 to 8As shown, the first drilling device 40 includes a connecting support 41, a first drilling motor 42, and a motor lifting cylinder 43. The connecting support 41 is located at the upper end of the first housing 11. The front end face of the connecting support 41 is provided with a cylinder mounting seat 44 extending upwards towards the second housing 12. The motor lifting cylinder 43 is vertically mounted on the cylinder mounting seat 44. The front end face of the cylinder mounting seat 44 is vertically connected to a first motor mounting plate 45 via a guide rail slider. The rear end face of the first motor mounting plate 45 is provided with a cylinder top plate 431 connected to the piston rod end of the motor lifting cylinder 43. The first drilling motor 42 is vertically mounted on the first motor mounting plate 45.

[0030] In practice, the first drilling motor 42, which is vertically mounted on the first motor mounting plate 45, is driven by the motor lifting cylinder 43 to move up and down on the cylinder mounting base to perform vertical drilling on the upper end of the shoe last on the shoe last placement platform 20 located below.

[0031] In this embodiment, the sleeve feeding and clamping device 50 includes a fixed bracket 51, a movable bracket 52, a vibrating feeding plate 53, a material picking and moving mechanism 54, and a feeding and clamping mechanism 55. The fixed bracket 51 is mounted on the front end face of the connecting support 41. A bracket lifting cylinder 511 is vertically mounted on the top of the fixed bracket 51. The top of the movable bracket 52 is connected to the piston rod end of the bracket lifting cylinder 511 and is located inside the fixed bracket 51. The movable bracket 52 is driven by the bracket lifting cylinder 511 to move up and down inside the fixed bracket 51. There is a gap between the movable brackets 52 and the fixed bracket 51.

[0032] The feeding and pressing mechanism 55 is vertically mounted on one side of the movable support 52 via a connecting plate. The picking and moving mechanism 54 is connected to the front end face of the first housing 11 via a support plate 544 and is located below the feeding and pressing mechanism 55. The picking and moving mechanism 54 is provided with a receiving seat 541.

[0033] The vibrating feeder 53 is located on the rear side of the connecting support 41. The vibrating feeder 53 is provided with a sleeve discharge channel 531. One end of the sleeve discharge channel 531 is provided with a transmission pipe 532. The discharge end of the transmission pipe 532 is spaced above the receiving seat 541.

[0034] In practice, multiple sleeves are placed in the vibrating feeding plate 53. The sleeves are moved out of the sleeve discharge channel 531 and sent into the transmission pipe 532 by vibration. The sleeves fall freely in the transmission pipe 532 and fall directly onto the receiving seat 541 on the material picking and moving mechanism 54. The material picking and moving mechanism 54 transfers the sleeves in the receiving seat 541 to the feeding and pressing mechanism 55. The feeding and pressing mechanism is connected to one side of the moving bracket 52 and is driven to move up and down by the bracket lifting cylinder 511 to press the sleeves into the hole at the top of the shoe last.

[0035] Specifically, the feeding and pressing mechanism 55 includes a transverse drive cylinder 551 and a transverse plate 552. One end of the transverse plate 552 is vertically provided with a sleeve suction head 553. The transverse drive cylinder 551 is used to drive the transverse plate 552 to move towards the shoe last placement platform 20.

[0036] In practice, the suction head 553 is connected to a suction pipe. The negative pressure suction force generated is used to adsorb and move the sleeve on the material seat 541. The lateral movement drive cylinder 551 drives the suction head 553 on the lateral movement plate 552 to move laterally to above the hole at the top of the shoe last. The support lifting cylinder 511 drives the lifting movement to press the sleeve into the hole at the top of the shoe last.

[0037] Specifically, the material moving mechanism includes an extension cylinder 542 and a lifting cylinder 543. The extension cylinder 542 is stacked on the support plate 544, and the lifting cylinder 543 is vertically arranged. One side of the lifting cylinder 543 is connected to the piston rod end of the extension cylinder 542, and the receiving seat 541 is arranged at the piston rod end of the lifting cylinder 543.

[0038] In practice, after the sleeve falls into the receiving seat 541, the extension cylinder 542 drives the lifting cylinder 543 to extend. The lifting cylinder 543 drives the receiving seat 541 to rise and connect with the sleeve suction head 553. The sleeve suction head 553 adsorbs the sleeve in the receiving seat 541. The lifting cylinder 543 and the extension cylinder 542 are reset, waiting for the next receiving.

[0039] In this embodiment, the shoe last placement platform 20 includes a first adjusting slide 21 and a shoe last fixture 22. The shoe last fixture 22 is adjustablely mounted on the first adjusting slide 21, and the first adjusting slide 21 can be adjusted by moving up and down.

[0040] In practical implementation, the shoe last fixture 22 includes two spaced-apart platforms: a front platform and a rear platform. The front platform is used to place the forefoot portion of the shoe last, and the rear platform is used to place the heel portion. To accommodate shoe lasts of different sizes, the front platform can be moved up and down via a screw-driven handwheel slider, and the rear platform can be moved back and forth via a screw-driven handwheel slider. The first adjusting slide 21 is moved up and down via a connecting sleeve and a screw jack.

[0041] In this embodiment, the shoe last fixing gripper 30 includes a mounting support 31, a gripper mounting plate 32, and a pneumatic linkage gripper 33. The mounting support 31 is vertically disposed at the upper end of the second housing 12 and located behind the shoe last placement platform 20. The gripper mounting plate 32 is vertically stacked on the mounting support 31. The pneumatic linkage gripper 33 is vertically connected to the gripper mounting plate 32 and is connected to the drive switch 34 via a pipeline. The pneumatic linkage gripper 33 can adapt to shoe lasts of different shapes and sizes, and quick shape change can be achieved through simple adjustments to meet diverse production needs.

[0042] In this embodiment, the gripper plate is provided with an elongated hole 321 along its height direction. The installation height of the pneumatic linkage gripper 33 can be adjusted through the elongated hole 321, thereby adapting to gripping shoe lasts of different sizes and specifications.

[0043] In this embodiment, the drive switch 34 is a pedal switch, which is located at the bottom front side of the second housing 12 for easy operation by workers.

[0044] In this embodiment, the second drilling device 60 includes a mounting base 61, a second adjusting slide 62, a second motor mounting plate 63, a second drilling motor 64, and a motor transverse cylinder 65.

[0045] Mounting stand 61 is located on the upper surface of the second housing 12. The second adjusting slide 62 is located on the mounting stand 61. The second motor mounting plate 63 is connected to the upper surface of the second adjusting slide 62 via a horizontally arranged guide rail slider. The second drilling motor 64 is horizontally arranged on the second motor mounting plate 63. The motor transverse cylinder 65 is used to drive the second drilling motor 64 on the second motor mounting plate 63 to move horizontally on the second adjusting slide 62.

[0046] In practice, the second drilling motor 64 on the second motor mounting plate 63 is driven by the motor lateral movement cylinder 65 to drill holes in the side of the shoe last on the shoe last placement table 20. The second adjusting slide 62 moves back and forth via a screw, hand crank, and slider to adjust the drilling position on the side of shoe lasts of different sizes.

[0047] The shoe last drilling and pressing machine provided by this invention, compared with the prior art, only requires placing the shoe last on the shoe last placement table 20, clamping and fixing it by the shoe last fixing claw 30, drilling holes in the upper and side surfaces of the shoe last by the first drilling device 40 and the second drilling device 60, and then feeding and pressing the sleeve into the pre-drilled hole at the upper end of the shoe last by the sleeve feeding and pressing device 50 to complete the processing.

[0048] By integrating the first drilling device 40, the second drilling device 60, and the sleeve feeding and pressing device 50 onto the vertical machine base 10, the drilling and pressing processes of shoe lasts can be completed continuously on the same equipment, reducing the number of equipment changes and material handling time, effectively improving processing efficiency and reducing the labor intensity of workers.

[0049] Where there is no conflict, the above embodiments and features can be combined with each other.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
