Precise indexing clamp special for turning

Abstract

The invention discloses a precise indexing clamp special for turning, and belongs to clamps special for turning in the technical field of machining equipment. According to the precise indexing clamp special for turning, multipoint stress is achieved, and the clamp is suitable for clamping workpieces of multiple sizes. According to the technical scheme, the clamp comprises a clamp body, and a cross sliding groove is formed in the clamp body; a clamping jaw is arranged in each sliding groove body of the cross sliding groove, and a clamping jaw drive mechanism is arranged on the back face of the clamp body and comprises a large conical gear and a plurality of sets of lead screws; the large conical gear is mounted on the clamp body, and each lead screw is arranged at the position corresponding to the position of the corresponding clamping jaw; the lead screws are sleeved with threaded holes of the clamping jaws, and are in threaded connection with the clamping jaws; and a small conical gear is arranged on one side, close to the large conical gear, of each lead screw, and the small conical gears on the lead screws are meshed with the large conical gear. The precise indexing clamp is suitable for being used in turning.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing equipment and relates to a precision indexing special fixture for turning processing. Background technique [0002] Lathe processing is a part of mechanical processing. Lathe processing mainly uses a turning tool to turn a rotating workpiece. Drills, reamers, reamers, taps, dies and knurling tools can also be used on the lathe for corresponding processing. Lathes are mainly used to process shafts, discs, sleeves and other workpieces with rotating surfaces. They are the most widely used type of machine tool processing in machinery manufacturing and repair factories. [0003] The workpiece rotates, and the turning tool performs cutting processing of linear or curved movement in the plane. Turning is generally performed on a lathe to process the inner and outer cylindrical surfaces, end surfaces, conical surfaces, forming surfaces and threads of the workpiece. When turning the inner and ou...

Problems solved by technology

[0005] However, when the workpiece is clamped by six force points, it cannot effectively ensure that all six force points act on the workpiece, so the clamping effect of the lathe clamp on the workpiece is low

In addition, the existing lathe clamps generally clamp the workpiece through three jaws, and the three jaws can be moved to clamp workpieces of different sizes; the three force points act on the workpiece, and the distance between the workpiece and the fixture There are fewer action points, and the force between the fixture and the workpiece is limited, so that the clamping effect of the fixture on the workpiece is low

And when the existing workpieces are turned, most of the workpieces need to uniformly process a plurality of grooves or holes on their end faces, so the workpieces need to be indexed, and the prior art basically uses manual labor to perform indexing. Carry out measurement indexing, so that the indexing effect of the special tooling for indexing is low, and the indexing accuracy is poor
