Description

Rotating clamp for machining parts Technical Field The utility model relates to the field of fixtures, in particular to a rotary fixture for machining parts. Background Mechanical parts, also known as mechanical elements, are the basic elements that make up a machine, are the individual pieces that make up the machine and are not separable, and are a subject of research and design of the mechanical base in various devices, and are a general term for parts and components. The spare part is required to be clamped and fixed with the spare part that waits to process in production, but anchor clamps in prior art scheme are because self structure is comparatively simple, and after carrying out the centre gripping to the spare part fixed, can not adjust the angle of spare part once more, this just leads to anchor clamps to have the limitation in practical application, consequently hardly satisfies the processing demand. Disclosure of utility model The embodiment of the application provides the rotating clamp for processing the parts, which solves the technical problem that the clamp in the prior art is difficult to meet the processing requirement because the clamp has a simple structure and can not adjust the angle of the parts again after clamping and fixing the parts, so that the clamp has limitation in practical application. The technical scheme adopted by the embodiment of the application is as follows: The rotary clamp for machining the parts comprises a bottom plate, a supporting plate for supporting the parts, a positioning device for positioning the parts, an annular plate arranged at the bottom end of the supporting plate, an inner gear arranged on the inner side of the annular plate, an arc-shaped sliding block for supporting the annular plate, an annular sliding rail for limiting sliding of the arc-shaped sliding block and a rotating device arranged on the bottom plate, wherein a plurality of groups of positioning devices arranged in a circumferential array are arranged on the supporting plate, the bottom end of the annular plate is connected with a plurality of groups of arc-shaped sliding blocks arranged in a circumferential array, each group of arc-shaped sliding blocks slide on the annular sliding rail, the rotating device is connected with the inner gear in a transmission mode, and the annular sliding rail is arranged on the bottom plate. The rotating device comprises an external gear and a driving device arranged on the top of the bottom plate, wherein the external gear is arranged on an output shaft of the driving device, and the external gear is meshed with the internal gear.
