Description

Technical Field

[0001] The utility model relates to the technical field of metal product processing fixtures, in particular to a circumferential metal product processing and fixing fixture. Background Art

[0002] With the development of society, fixtures are divided into three types: automatic, semi-automatic and manual. Among them, semi-automatic fixtures also use cylinders as the driving source, and clamp the processed parts by driving the clamping block to squeeze, so as to ensure the stability during cutting;

[0003] In the existing semi-automatic clamps, in order to increase the application range of the existing clamps, multiple cylinders are generally used for coordinated clamping, and the control structure is relatively complex; and when clamping a circular workpiece, the surface of the general clamp is flat, while the surface of the workpiece is curved, and the fixing effect is poor. Even if a clamp with an arc surface is used, the curvature of the clamp is fixed. If circular workpieces of different sizes need to be processed, the arc surface will also change, so it is still impossible to effectively fix them. At the same time, it is not convenient to switch the position of the metal parts during the clamping process, so a circular metal product processing and fixing clamp is needed. Utility Model Content
