Bearing ring digital control lathe clamper

Abstract

The invention discloses a bearing ring numerically-controlled lathe clamp which belongs to the technical field of machine tool elements. The clamp comprises a base arranged at one end of a lathe spindle, six waisted through holes are evenly distributed at the lateral side of the base, and a collet which is in a circular platform shape and provided with an inner hole is fixedly connected to the end surface of the base; the collet comprises six sector blocks, wherein a clearance between every two sector blocks forms a long and narrow groove; in addition, the long and narrow grooves are communicated with the waisted through holes; and each sector block is formed by splicing an internal sector block and an external sector block, an inner circular arc of each internal sector block forms an inner hole provided with a notch, and the internal sector blocks and the external sector blocks are fixedly connected by bolts. When the inner hole of the clamp is worn or workpieces of different specifications are required to be installed, the internal sector blocks just need to be replaced, the invention greatly saves the maintenance cost and the replacement cost, is convenient for the processing, and saves the time and the labor during the processes of dismounting and installing, thereby improving the whole production efficiency.

Description

technical field [0001] The invention discloses a clamp for a numerically controlled lathe for a bearing ring, which belongs to the technical field of machine tool components. Background technique [0002] In the bearing ring CNC lathe, the conventional fixtures use integral chucks. After several wears, the chucks can no longer be used because the inner hole is too large, and the life is short. What's more, if the user wants to replace If the product specifications are different, the entire collet must be replaced, and the integral collet is troublesome to manufacture and expensive, so the replacement cost will be greatly increased, and there are many parts involved in the replacement of the collet, it is very inconvenient to disassemble and install, and generally consumes Two or three hours will affect the production schedule. Contents of the invention [0003] The present invention aims at the deficiencies in the prior art, and aims to provide a fixture for a bearing rin...
