Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing clamps, in particular to a small vise clamp. Background Art

[0002] A flat-mouth vise is a type of fixture used in mechanical production. It clamps and fixes workpieces by bringing two parallel clamping plates close together. It is widely used in processing planes, grooves, and other aspects. The vises commonly used in the market currently have the following problems: 1. There are usually only two clamping plates, and only one part can be clamped at a time. It is not possible to process a large number of parts. When multiple parts need to be clamped, the number of vises needs to be increased, and the adaptability is poor; 2. The existing vises can only clamp parts with relatively regular structures, and the types of clamped parts are single. For frame-type parts, when clamping, excessive clamping will cause the frame parts to deform, affecting the processing effect. At the same time, this clamping device for machine tools limits the use of users to a certain extent. Utility Model Content
