Description

Technical Field

[0001] This application relates to the technical field of metal product processing, and particularly to a positioning fixture for metal product processing. Background Art

[0002] The metal product industry includes the manufacturing of structural metal products, metal tools, containers and metal packaging containers. Metal processing requires the use of positioning fixtures to fix them for subsequent processing operations.

[0003] For example, the Chinese utility model patent with the publication number CN220636998U discloses a positioning fixture for metal product processing, which includes a base. One end of the base is fixedly connected with a fixed plate. The side wall of the fixed plate is fixedly connected with a hydraulic telescopic rod. One end of the hydraulic telescopic rod is fixedly connected with a left connecting plate. One end of the base is fixedly connected with a right connecting plate. The opposite ends of the left connecting plate and the right connecting plate are both provided with chutes. The inner cavities of the two chutes are both provided with lead screws. The lead screws are both slidably connected with upper sliders and lower sliders. The opposite side walls of the two upper sliders are both fixedly connected with upper clamping blocks. The opposite side walls of the two lower sliders are both fixedly connected with lower clamping blocks. In this utility model, when the driving motor is started, it drives the upper slider and the lower slider to approach each other, thereby driving the upper clamping block and the lower clamping block to approach each other. Then, the metal product can be clamped according to the width of the metal product, so that the device can be adjusted according to the sizes of different metal products, improving the flexibility and practicability of the fixture.
