The locking element 123 is located at the end of the clamping element 122, specifically for supplementary fixing of the ends of the shoe last, forming a complete three-dimensional clamping system.

[0024] The clamping element 122 includes a movable rod 1221, a movable block 1223, and a clamping block 1224; one end of the movable rod 1221 is inserted and movable on the locking drive assembly 23, the movable block 1223 is disposed on both sides of the movable rod 1221, and the clamping block 1224 is disposed on the movable block 1223; one end of the locking drive assembly 23 is connected to drive the movable rod 1221 to drive the clamping block 1224 to open and close and clamp through the movable block 1223. In this embodiment, the movable rod 1221 serves as the core transmission component, with one end connected to the locking drive assembly 23. Under the action of driving force, it can reciprocate. The movable blocks 1223 are symmetrically distributed on both sides of the movable rod 1221 to ensure balanced force.

In this embodiment, the efficient and reliable shoe-making positioning and locking function is achieved through the coordinated action of the movable pull rod 1231, the expansion sleeve 1232, and the expansion push block 1233. The movable pull rod 1231 is connected to the movable rod 1221 at one end and the expansion sleeve 1232 is sleeved at the other end.

In this embodiment, the cooperation structure between the transmission insertion pin 131 and the transmission wheel 132 ensures the stability of the power input. The synchronous belt 133 transmission system smoothly transmits the power to the driven wheel 134, which ultimately drives the movable rod 1221 to complete the clamping action. The coordinated work of the locking drive assembly 23 and the transmission insertion pin 131 enables the clamping element 122 and the locking element 123 to simultaneously apply uniform locking force to the side and end of the shoe last.

In this embodiment, through the coordinated cooperation of the first positioning element 221 and the second positioning element 223, the precise positioning of the shoe last fixing component 12 is achieved. The first positioning element 221 is symmetrically disposed on both sides of the fixture transmission component 13, which can effectively constrain the lateral displacement of the shoe last fixing component 12 and ensure its lateral stability during processing. The second positioning element 223 is arranged near the end position of the locking transmission module 26, which can accurately control the axial position of the shoe last fixing component 12. This improves the positioning accuracy, keeps the shoe last in a stable posture during processing, and avoids processing deviations caused by inaccurate positioning.

The linear motion of the cylinder piston rod drives the first positioning rotating shaft 2213 to rotate, thereby driving the positioning head to complete the positioning action, ensuring the accuracy of positioning and improving the flexibility of the mechanism. The positioning head can be replaced and adapted according to different shoe types, enhancing the versatility of the mechanism.

[0029] The second positioning element 223 includes a second positioning seat 224, a second positioning push block 225, and a second positioning head 226. The second positioning seat 224 is disposed in the locking transmission module 26, the second positioning push block 225 is disposed within the second positioning seat 224, and the second positioning head 226 is disposed on the second positioning push block 225. One end of the second positioning head 226 is arc-shaped. In this embodiment, by disposing of the second positioning seat 224 on the locking transmission module 26, a stable connection between the positioning mechanism and the transmission system is achieved, ensuring the reliability of the overall structure. The arc-shaped end structure of the second positioning head 226 better adapts to the curved surface of the shoe material, providing flexible contact positioning and effectively preventing damage to the shoe surface during positioning.

The pressing head 2523 adopts an adaptive design to ensure complete fit with different shoe last shapes, thereby improving the standardization of shoe manufacturing.

[0031] The locking transmission module 26 includes a locking transmission wheel 261, a locking transmission belt 262, and a locking driven wheel 263. A locking transmission pin 264 passes through the locking driven wheel 263. One end of the insertion transmission rod 2512 is movably mounted on the locking transmission wheel 261. The locking transmission belt 262 is respectively sleeved on the locking transmission wheel 261 and the locking driven wheel 263. One end of the locking transmission pin 264 cooperates with the transmission insertion pin 131. One end of the drive insertion module 25 cooperates with the locking transmission wheel 261 through the insertion drive element 2511, so that the locking transmission pin 264 cooperates with the transmission insertion pin 131, so that the jig transmission assembly 13 in the shoe last fixing assembly 12 can be driven to transmit power to the clamping element 122 and the locking element 123 for the shoe last fixing assembly 12 to fix the shoe last. In this embodiment, a stable transmission system is formed by locking the transmission wheel 261 and driven wheel 134 through a transmission belt. The precise cooperation between locking the transmission pin 264 and transmission insertion pin 131 ensures the reliability of power transmission. When the drive insertion module 25 drives the locking transmission wheel 261 to operate through the insertion drive element 2511, the power is transmitted to the fixture transmission assembly 13 through the transmission belt, driven wheel 134 and transmission pin assembly, thereby achieving stable clamping of the shoe last.
