Description

Technical Field

[0001] The utility model relates to the technical field of shoe last clamping devices, in particular to a shoe last positioning clamping device. Background Art

[0002] The shoe last is the mother of the shoe. It is the molding mold of the shoe. The shoe last not only determines the shape and style of the shoe, but also determines whether the shoe fits the foot and whether it can protect the foot. Therefore, the design of the shoe last must be based on the foot shape, but it cannot be the same as the foot shape, because the foot changes in shape, size, stress, etc. when it is static and in motion. In addition, the shoe variety, style, processing technology, raw and auxiliary material properties, wearing environment and conditions are also different. The shape and size of each part of the shoe last cannot be exactly the same as the foot shape. Therefore, modern shoe last design involves multiple disciplines and requires very high manual skills and experience.

[0003] For example, a positioning and clamping device for a shoe last (Announcement No.: CN216822027U) includes a base, a mounting seat arranged on the base for mounting the shoe last, two clamping claws relatively arranged on the base and rotatable to clamp or release the mounting seat, and a driving mechanism for controlling the clamping claws to clamp or release the mounting seat; the driving mechanism includes a moving block arranged in the base and movable up and down and a driving member driving the moving block to move up and down; the moving block is provided with two guide surfaces inclined downward from its top and respectively opposite to the two clamping claws; a roller that can move up and down along the guide surface is provided at the bottom of the clamping claw; when the shoe last is installed on the device, the driving member drives the moving block to move downward so that the roller moves downward along the guide surface, so as to drive the clamping claw to rotate inward to clamp the mounting seat; when the shoe last is processed, the driving member drives the moving block to move upward so that the roller moves upward along the guide surface, so as to drive the clamping claw to rotate outward to release the mounting seat, thereby completing the disassembly of the shoe last; the overall operation of the driving mechanism is simple, which is convenient for the installation and disassembly of the shoe last.

[0004] When the device replaces the shoe last, it is necessary to drive the clamping claw to loosen the clamping of the mounting seat through the driving member, and the shoe last can be replaced only by removing the shoe last from the positioning pin and the steel ball expansion pin. The shoe last replacement and installation process is cumbersome, resulting in low efficiency in the sole spraying preparation stage and is not conducive to the rapid replacement of different shoe lasts. Therefore, we need to propose a shoe last positioning and clamping device. Utility Model Content
