Abstract

The invention provides a rotary indexing clamp. The clamp comprises a support, a clamp body, a nut and a tightening cover. A taper through hole in the clamp body is matched with a corresponding circular cone on the support through a conical surface, and coaxiality of the support and the clamp body is achieved; a cylinder through hole in the clamp body is matched with a corresponding cylinder on the support through a conical surface, the fixed relative positions of the support and the clamp body are achieved; the angle indexes I on the clamp body and the corresponding angle indexes II on the support are correspondingly arranged, and rotary positioning at any angles is achieved; and fixation of the clamp body and the support is achieved on the clamp body through the nut. Connection is achieved through the support and fixtures like a vice on a machine tool. The indexes are arranged on the support and the clamp body correspondingly, rotation and fixed clamping of tiny axis parts at different angles can be achieved, and tiny structures can be machined on different-angle surfaces of cylinder faces of different axis parts. The rotary indexing clamp is simple in structure, low in cost andconvenient to operate.

Description

technical field [0001] The invention belongs to the field of micromachining, and in particular relates to a rotatable indexing fixture. Background technique [0002] In modern scientific research and production, it is necessary to process micro-structures such as micro-holes on the surface of some micro-shaft parts at different angles. The processing methods of these micro-structures often use technologies such as micro-EDM, femtosecond laser processing and precision milling. However, many equipment do not With multi-axis linkage function, the clamping of the parts is processed by "V" block clamping on the tiny vise, so that the parts can only rotate at some special angles, and the microstructure processing on the cylindrical surface of shaft parts with different angles cannot be realized. . Contents of the invention [0003] In order to solve the problem of machining fine structures on the surface of tiny shaft parts at different angles. The invention provides a rotatab...
