Lathe tailstock hole grinding fixture

Abstract

The invention relates to a lathe tailstock hole grinding fixture. The fixture comprises a core shaft (1); a tapered guide sleeve (2) is arranged in the middle of the core shaft (1); a taper sleeve (3) is arranged on the guide sleeve (2); the taper sleeve (3) consists of three taper sleeve blocks; a grinding spiral groove (4) is formed on the surface of each of the three taper sleeve blocks, a spring mounting groove (6) is formed on each of the front and rear sides of each grinding spiral groove (4), a spring (5) is arranged in each spring mounting groove (6), and the three taper sleeve blocks are fixed through the springs (5); a washer (9) and an adjusting nut (10) are arranged at each of the front end and the rear end of the taper sleeve (3); and grinding sand (7) is arranged on the surface of the taper sleeve (3). The lathe tailstock hole grinding fixture is simple in structure and convenient to operate, can be used for lathes of the same model, is low in manufacturing cost and high in grinding efficiency, and can effectively ensure the precision control of surface roughness, roundness, cylindricity and the like of a lathe tailstock hole.

Description

technical field [0001] The invention relates to a tooling specially used for precision grinding, which is mainly used for precision grinding processing of tailstock holes of ordinary lathes, and belongs to the technical field of precision repair of metal cutting equipment. Background technique [0002] In the precision grinding and repair of the tailstock hole of ordinary lathes, the traditional method is to make grinding rods according to the size of the tailstock hole. The precision grinding is characterized by increasing size and decreasing surface roughness. With the change of the size of the tailstock hole after grinding, the grinding rods need to be prepared again. At the same time, to reduce the surface roughness, it is necessary to gradually use higher mesh grinding sands. This determines that even if multiple grinding rods are prepared, it is difficult to completely Meet the instant changes in the size and precision of the grinding process. Contents of the invent...
