Plane grinding machine

Abstract

The invention relates to a plane grinding machine. The plane grinding machine comprises a base table, the upper side of the base table is fixedly connected with a rack, the rack is internally provided with a first driving mechanism and a main shaft, the main shaft is connected with the output end of the first driving mechanism, and the bottom of the main shaft extends to the upper side of the base table and is provided with an upper tray; and a grinding wheel with the working direction facing downwards is installed on the lower side of the upper tray, multiple lifting structures and polishing heads which are connected with one another are installed in the base table, and the polishing heads work upwards and are arranged on the lower side of the grinding wheel. The polishing heads face upwards, the grinding wheel faces downwards, and meanwhile, the grinding wheel can be driven to rotate through the first driving structure and the main shaft, the polishing heads can be driven to move in the vertical direction through the lifting structures, workpieces can be installed on the upper sides of the polishing heads through a clamp, and secondary adjustment can be avoided.

Description

Technical field [0001] The present invention relates to the field of grinding machines, in particular a planar mill. Background technique [0002] The planar mill is a grinding machine for grinding the surface of the workpiece, mainly applied to the high-precision plane of the grinding workpiece, inner and outer cylindrical surface, conical surface, spherical threaded wool and other profiles, and the grinder adopts stepless speed control system control. It is easy to adjust the abrasive speed suitable for grinding the various components. Most of the existing grinding machines use electrical-air proportional valve closed loop feedback pressure control, and the pressure device can be independently regulated. The upper plate is set, and the crisp workpiece is effectively prevented. [0003] According to the inspection, China's patent discloses a planar mill (public number: CN108214282B), which includes: a base; a first rotating unit, disposed on the base, the first rotation unit has...

AI Technical Summary

Problems solved by technology

[0004] Existing surface grinding machines include a polishing head and a grinding disc. The polishing head faces down and the grinding disc faces up. Vertical position, this method has difficulty in positioning and the possibility of secondary adjustment of the position. It also needs to move the ceramic plate and fixture multiple times when taking it out, which affects the efficiency of workpiece pick-and-place, resulting in slower working efficiency of the device
