Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a positioning processing device for special-shaped large plane parts. Background Art

[0002] In the prior art, in the field of mechanical processing, in the process of modern industrial production and manufacturing, many products need to be processed and produced by machine tools. During the machine tool processing, the processed parts need to be positioned so that the processed parts will not be displaced during the processing process, and the produced parts can meet customer requirements. During the processing, some thin plate parts are often processed. In the prior art, two clamps are generally used to clamp and fix the thin plate parts. For example, a bench vise will produce large vibrations, affecting the surface processing quality; the pressure plate and pressure block will occupy a part of the processing surface, and the secondary processing will produce cutting marks that also affect the surface processing quality; the suction cup magnet will cause the plate to yield and stick together, causing the finished product to deform. The existing fixing method is that the tooling fixture structure is large, which is not convenient for operation when processing parts, and the parts may shake after clamping. Second, the parts may slide down during the processing, affecting the processing accuracy of the parts, and the fixtures in the prior art can only clamp and position regular parts, and cannot accurately position special-shaped large flat parts.
