[0004] When processing shoe materials that need to be processed from different angles, the above-mentioned device requires first releasing the clamp, then flipping the shoe material, and then mechanically clamping it again. This is time-consuming and labor-intensive, which can easily lead to slower production efficiency. Furthermore, it cannot adjust the height, resulting in low practicality. Therefore, we propose a clamping device for shoe material processing to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a clamping device for shoe material processing, so as to solve the problems mentioned in the background art that the existing shoe material clamping device requires first releasing the clamp, then flipping the shoe material and then mechanically clamping it again when processing shoe materials that need to be processed from different angles. This is time-consuming and labor-intensive, which can easily lead to slow production efficiency and cannot adjust the height, resulting in low practicality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for shoe material processing, comprising a worktable, a fixed frame installed at the middle position of the front end of the top of the worktable, an electric guide rail installed at the rear end of the top of the worktable, a third drive motor installed on one side of the electric guide rail, a slider slidably connected inside the electric guide rail, a movable frame installed on the top of the slider, a lead screw installed on the inner top of both the fixed frame and the movable frame, a first drive motor installed on the top of the lead screw via the fixed frame and the movable frame respectively, a nut seat slidably installed on the outer wall of the lead screw, a second drive motor installed at the rear end of the nut seat at the front end, a first clamping device installed on the output shaft of the second drive motor, a fourth drive motor installed at the front end of the nut seat at the rear end, a fixed plate installed on the output shaft of the fourth drive motor, second hydraulic cylinders installed on both sides of the front end of the fixed plate, a bearing installed at the other end of the second hydraulic cylinder, and a second clamping device installed at the front end of the bearing.

The first abutment plate is fixedly mounted on the bottom of the first threaded rod through the upper plate of the first U-shaped clamp. The first throttle is mounted on the top of the first threaded rod.

[0008] Preferably, the second clamping device includes a second U-shaped clamp, a second threaded rod, a second abutment plate, and a second throttle. The second U-shaped clamp is located at the front end of the bearing. The second threaded rod is installed on the top of the second U-shaped clamp. The second abutment plate is fixedly installed on the bottom of the second threaded rod through the upper plate of the second U-shaped clamp. The second throttle is installed on the top of the second threaded rod.

[0009] Preferably, a limit rod is installed on one side of each of the two lead screws, and the two limit rods are fixedly connected to the fixed frame and the movable frame, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) This utility model clamps both ends of the shoe material using a first clamping device and a second clamping device respectively. The first clamping device can be rotated by a second drive motor, and the fixed plate can be rotated by a fourth drive motor. The second clamping device can be rotated indirectly by the connection of the fixed plate, the second hydraulic cylinder and the bearing. The shoe material can be rotated by the combined action of the second drive motor and the fourth drive motor, which facilitates the processing of the shoe material at different angles. The lead screw can be rotated by the first drive motor, and the rotation of the lead screw can move the nut seat up and down, thereby realizing the height adjustment of the shoe material. This solves the problem that existing shoe material clamping devices require the clamping to be released first, then the shoe material to be flipped and then mechanically clamped again when processing shoe materials that need to be processed from different angles. This is time-consuming and laborious, which can easily lead to slow production efficiency and low practicality because the height cannot be adjusted.

[0015] (2) The second clamping device can be moved left and right by the combined action of the electric guide rail, the third drive motor and the slider. After the second clamping device is moved to a suitable position, one of the second hydraulic cylinders is extended and the other second hydraulic cylinder is retracted. Under the action of the bearing, the horizontal angle of the second clamping device can be adjusted, so that the shoe material can be clamped from the side. At this time, the clamping and fixing of the shoe material by the first clamping device can be cancelled, so that the two ends of the shoe material can be processed according to the processing requirements, which improves the practicality and production efficiency of the device.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-4This utility model provides an embodiment of a clamping device for shoe material processing, comprising a workbench 1, a fixed frame 2 installed at the middle position of the front end of the top of the workbench 1, an electric guide rail 13 installed at the rear end of the top of the workbench 1, a third drive motor 14 installed on one side of the electric guide rail 13, a slider 15 slidably connected inside the electric guide rail 13, a movable frame 16 installed on the top of the slider 15, a lead screw 3 installed on the inner top of both the fixed frame 2 and the movable frame 16, a first drive motor 5 installed on the top of the lead screw 3 via the fixed frame 2 and the movable frame 16 respectively, a nut seat 6 slidably installed on the outer wall of the lead screw 3, a second drive motor 7 installed at the rear end of the nut seat 6 at the front end, and a first clamping device installed on the output shaft of the second drive motor 7. During clamping, one end of the shoe material is first clamped by the first clamping device, which includes a first U-shaped clamp 8, a first threaded rod 9, a first abutment plate 10, and a first rotary handle 11. The first U-shaped clamp 8 is located on the output shaft of the second drive motor 7. The first threaded rod 9 is installed on the top of the first U-shaped clamp 8, and the first abutment plate 10 is fixedly installed on the bottom of the first threaded rod 9 through the upper plate of the first U-shaped clamp 8. The first rotary handle 11 is installed on the top of the first threaded rod 9. One side of the shoe material is placed on the top of the lower plate of the first U-shaped clamp 8. Rotating the first rotary handle 11 causes the first threaded rod 9 to rotate, causing the first abutment plate 10 to move down until the first abutment plate 10 is in contact with the shoe material, thereby clamping one end of the shoe material. The nut seat 6 located at the rear end... A fourth drive motor 18 is installed at one end. A fixing plate 19 is installed on the output shaft of the fourth drive motor 18. The fourth drive motor 18 and the fixing plate 19 are fixedly connected by a first hydraulic cylinder 17. Second hydraulic cylinders 20 are installed on both sides of the front end of the fixing plate 19. A bearing 21 is installed at the other end of the second hydraulic cylinder 20. Fixing blocks 22 are installed on both sides of the bearing 21. The fixing blocks 22 are fixedly connected to the second hydraulic cylinders 20. A second clamping device is installed at the front end of the bearing 21. The second clamping device includes a second U-shaped clamp 23, a second threaded rod 24, a second abutment plate 25, and a second throttle 26. The second U-shaped clamp 23 is located at the front end of the bearing 21. The second threaded rod 24 is installed on the top of the second U-shaped clamp 23. The bottom of the second threaded rod 24 passes through the second... The upper plate of the U-shaped clamp 23 is fixedly equipped with a second abutment plate 25, and the top of the second threaded rod 24 is equipped with a second handle 26. The other end of the shoe material is clamped and fixed by the second clamping device. Rotating the second handle 26 causes the second threaded rod 24 to rotate, causing the second abutment plate 25 to move downward until the second abutment plate 25 is in contact with the shoe material, thereby clamping the other end of the shoe material. The second drive motor 7 can drive the first clamping device to rotate, and the fourth drive motor 18 can drive the fixed plate 19 to rotate. The connection between the fixed plate 19, the second hydraulic cylinder 20, and the bearing 21 can indirectly drive the second clamping device to rotate. The combined action of the second drive motor 7 and the fourth drive motor 18 can rotate the shoe material, which is convenient for processing the shoe material at different angles.The device improves production efficiency. The first hydraulic cylinder 17 drives the second clamping device to move back and forth, facilitating the clamping and fixing of shoe materials of different lengths, thus enhancing its practicality. The first drive motor 5 drives the lead screw 3 to rotate, which in turn moves the nut seat 6 up and down, allowing for height adjustment of the shoe material. This facilitates processing for workers of different heights, further improving the device's usability. When processing the ends of the shoe material is required, the second clamping device is removed from the material. The combined action of the electric guide rail 13, the third drive motor 14, and the slider 15 drives the moving frame 16 to move left and right, thereby moving the second clamping device left and right. After moving the second clamping device to the appropriate position, one of the second hydraulic cylinders 20 extends while the other retracts. Under the action of the bearing 21, the horizontal angle of the second clamping device can be adjusted, allowing for clamping of the shoe material from the side. At this point, the first clamping device can be removed from the material, enabling processing of both ends of the shoe material according to processing requirements, thus improving the device's practicality and production efficiency. ,

[0023] Please see Figure 1 and Figure 3 Each of the two lead screws 3 is equipped with a limiting rod 4 on one side. The two limiting rods 4 are fixedly connected to the fixed frame 2 and the movable frame 16 respectively. The limiting rods 4 can limit the nut seat 6, which can prevent the nut seat 6 from rotating when moving up and down and affecting the clamping and fixing of the shoe material, thus facilitating the positioning of the shoe material.

[0024] Please see Figure 1 and Figure 4 The bottom of the first abutment plate 10 and the second abutment plate 25 are both equipped with protective pads 12, and the inner top of the first U-shaped clamp 8 and the second U-shaped clamp 23 are both equipped with protective pads 12. The protective pads 12 can protect the surface of the shoe material from the direct action of the clamping force of the clamp, and avoid damage and deformation of the surface of the shoe material during the clamping process. The protective pads 12 can also change the shape of the clamping surface, making the shoe material more secure during the clamping process and ensuring that the shoe material remains stable during the processing.
