The support frame 1 is provided with the fixing component 2, the lower inner side of the support frame 1 is fixedly connected to a support plate 8, and the top of the support plate 8 is fixedly connected to the clamping component 3.

[0028] The fixed component 2 includes a servo motor 21, which is located on one side of the top of the support frame 1. The output shaft of the servo motor 21 is fixedly connected to a bidirectional threaded rod 22. The end of the bidirectional threaded rod 22 away from the servo motor 21 is provided with a rotating shaft to facilitate its rotation inside the support frame 1. Two rotating cylinders 23 are threadedly connected to the outer side of the bidirectional threaded rod 22. A trapezoidal slider 24 is sleeved on the outer side of the rotating cylinder 23. A positioning pin 25 is inserted through one side of the trapezoidal slider 24. A clamping plate 26 is fixedly connected to the top of the trapezoidal slider 24.

[0029] Specifically, the end of the rotating drum 23 is provided with multiple sets of positioning grooves 4 in a ring shape, and the outer side of the positioning pin 25 is in contact with the arc surface of the positioning groove 4. The positioning pin 25 can fix the position of the rotating drum 23 and prevent the rotating drum 23 from rotating relative to the trapezoidal slider 24 when the bidirectional threaded rod 22 drives the rotating drum 23 to move.

[0030] Furthermore, a trapezoidal groove 5 is provided at the top of the support frame 1, and a chip removal groove 6 is provided inside the support frame 1. The trapezoidal groove 5 and the chip removal groove 6 are connected. When processing the shoe sole, some waste chips may enter the interior of the trapezoidal slider 24. The chip removal groove 6 allows workers to clean the accumulated chips inside the trapezoidal slider 24, which is convenient and quick.

[0031] Furthermore, the clamping assembly 3 includes an electric push rod 31, the bottom end of which is fixedly connected to the support plate 8, and the top end of which is fixedly connected to a connecting rod 32. A smooth rod 33 is slidably connected through the interior of the connecting rod 32. There are two smooth rods 33, and two U-shaped rods 34 are sleeved on the outside of the smooth rods 33. The U-shaped rods 34 pass through the support frame 1 and the clamping plate 26 in sequence. A clamping block 35 is fixedly connected to the top end of the U-shaped rods 34, and a spring 36 is sleeved on the outside of the U-shaped rods 34. The lower part of the spring 36 is embedded inside the clamping plate 26.

[0032] It is worth noting that the bottom end of the clamping block 35 is fixedly connected to a protective pad 7, and the protective pad 7 is made of rubber to prevent friction damage to the surface of the sole when the protective pad 7 clamps the sole.

[0033] It is worth noting that a support rod 9 is fixedly connected to the bottom end of the support plate 8, and the end of the support rod 9 away from the support plate 8 is fixedly connected to the inner side of the support frame 1 to form a triangular structure, making it more stable.

[0034] It is worth mentioning that guide blocks 10 are fixedly connected to both ends of the light rod 33, and guide grooves 11 are opened on the inner side of the support frame 1. The guide blocks 10 slide inside the guide grooves 11, which guides the movement of the light rod 33.

[0035] The servo motor 21 and the electric push rod 31 are existing technologies and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" perspectives of this device are... Figure 1 The direction shown in the diagram is the reference.

[0036] Working principle: When the worker needs to process the shoe sole, first place the shoe sole to be processed on the support frame 1, with the sole placed between the two clamping plates 26. According to the length of the shoe sole to be processed, the worker pulls out the positioning pin 25 inside the trapezoidal slider 24, rotates the rotating cylinder 23, causing it to drive the trapezoidal slider 24 to slide on the outside of the bidirectional threaded rod 22. At the same time, the trapezoidal slider 24 slides inside the trapezoidal groove 5, effectively playing a guiding role. After moving the clamping plate 26 at the top of the trapezoidal slider 24 to the appropriate position, the positioning pin 25 is inserted into the inside of the trapezoidal slider 24. At the same time, under the action of the positioning groove 4, the positioning pin 25 fixes the position of the rotating cylinder 23, preventing the rotating cylinder 23 and the trapezoidal slider 24 from rotating relative to each other. Then, the servo motor 21 is started, driving the output shaft. The bidirectional threaded rod 22, which is fixed at the end, rotates. The bidirectional threaded rod 22 drives the rotating cylinder 23 and the trapezoidal slider 24 to slide inside the trapezoidal groove 5. At the same time, the trapezoidal slider 24 drives the clamping plate 26 at the top to self-center and clamp the sole. This eliminates the need for manual clamping of the sole, reducing the labor intensity of the workers and achieving a high degree of automation. Then, the electric push rod 31 is activated, pulling the connecting rod 32 downward. The connecting rod 32 pulls the smooth rod 33 downward, which drives the U-shaped rod 34 downward. The U-shaped rod 34 drives the clamping block 35 at the top to clamp the four corners of the sole. Under the action of the spring 36, it can prevent excessive clamping force from damaging the sole. It is convenient to clamp soles of different heights and sizes, and it can also effectively prevent the sole ends from lifting due to clamping, thus improving the clamping and fixing efficiency.
