Problems solved by technology

During the operation, it is easy to cause the surface polishing degree of the polished workpiece to be inconsistent with the set parameters, resulting in waste products
Obviously, the way of manually operating polishing equipment to place mold cores to be processed is far from meeting the requirements of precision polishing, and the processing efficiency is low, which is not suitable for mass production and cannot meet the needs of production

Abstract

The invention discloses a fixture, which comprises a workpiece bushing with a vertical cavity provided with multi-position-limiting step surfaces for fixing the workpiece. The lower part of the workpiece bushing is sleeved in a convex spherical bushing. The lower part of the spherical bushing is provided with a convex spherical body to fit the arc surface of the concave spherical bushing. The concave spherical bushing is set in a base that rotates coaxially with the rotation axis of the mold core. The base A straight rod mechanism with one end abutted against the side wall of the concave spherical bushing is provided on the top to realize the coarse / fine adjustment of the axis of the workpiece. The above-mentioned fixture has the advantages of high precision and multiple degrees of freedom, can fix workpieces of various standard caliber specifications, and perform position correction while clamping, which improves product quality, is convenient to use, and is low in price.

Description

Technical field [0001] The present invention relates to the technical field of polishing apparatus, and in particular, to a fixture. Background technique [0002] At present, various optical systems plays an irreplaceable role in military, civilian use, and increasing important role makes the accuracy requirements of optical systems on optical components. [0003] In the field of superficial processing, polishing is the most critical machining process in the production and processing of optical components. The effect of its processing will seriously affect the optical properties of the elements. During the process of machining the precision five-axis optically non-spherical polishing machine, because the workpiece to be processed is adsorbed on the magnetic chuck, the workpiece is determined by the thousands of tables, and the workpiece center is determined. Just reach the initial position of the processed. During the operation, it is easy to cause the surface polishing of the po...
