High-precision numerical control grinding machine and working method thereof

Abstract

The invention relates to the technical field of numerical control grinding machines, in particular to a high-precision numerical control grinding machine and a working method thereof. The high-precision numerical control grinding machine comprises a lathe table, the lathe table is provided with a mounting cavity, a mounting table is rotatably connected to the middle of the top of the lathe table, a rotation driving device is connected into the mounting cavity and used for driving the mounting table to rotate, and a special-shaped fixing table is arranged at the top of the mounting table. A grinding device can automatically adjust the grinding position of the side face of a special-shaped part by recognizing the side face of the special-shaped fixing table, on one hand, different grinding devices do not need to be prepared according to different special-shaped parts, the application range is widened, the machining cost of a factory is reduced, on the other hand, the grinding device can automatically adjust the grinding position, the adaptability to special-shaped parts is improved, manual control and adjustment are not needed, and dependence on manpower is reduced.

Description

technical field [0001] The invention relates to the field of numerically controlled grinding machines, in particular to a high-precision numerically controlled grinding machine and a working method thereof. Background technique [0002] A grinder is a machine tool used to grind the surface of a workpiece. In the existing grinding process, the workpiece is generally directly installed on the carrier of the grinding machine, the carrier is in a horizontal state and fixed with the grinding machine, and then the surface of the workpiece is ground according to the set program. [0003] Some patent cases related to high-precision CNC grinding machines have been disclosed in the prior art. The Chinese patent application number 201710474808.7 discloses a CNC grinding machine, which includes a machine tool body; a carrier mounted on the machine tool body; a grinding wheel assembly , set above the carrier, used to polish the workpiece on the carrier; the carrier is in rotation with t...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the grinding of workpieces by lathes is mostly designed for a single type of workpiece, and the adaptability of grinding is low. For workpieces of different shapes, corresponding grinding equipment needs to be adapted. The scope of application is relatively single, and the factory needs to prepare more. Grinding equipment increases the processing cost, and in the process of grinding, it is necessary to manually control the grinding position accurately, and the automatic recognition ability of the workpiece is weak, which makes the applicable ability of the grinding device limited
