Efficient polishing and grinding composite spindle

Abstract

The invention relates to an efficient polishing and grinding composite spindle comprising a machine body, a stator and a rotor. The stator and the rotor are arranged in the machine body. A front end cover is installed at the front end of the machine body. A bearing seat and a rear end cover are installed at the rear end of the machine body. A spindle core is installed in the middle of the rotor in an interference fit mode. A grinding assembly and a front bearing assembly are connected to the front portion of the spindle core. A polishing assembly and a rear bearing assembly are connected to the rear portion of the spindle core. The efficient polishing and grinding composite spindle has the beneficial effects that the grinding assembly is connected to the front portion of the spindle core, the polishing assembly is connected to the rear portion of the spindle core, and polishing and fine grinding of a workpiece and artware are completed on the same spindle.

Description

technical field [0001] The invention relates to the technical field of polishing and grinding machines, in particular to a high-efficiency polishing and grinding composite spindle. Background technique [0002] In modern society, almost all metal shells and plastic shells need to be polished, and the polishing process is a key process. The quality of the polishing process directly affects the beauty and quality of the product, the appearance smoothness and quality accuracy; such as mobile phone metal shells and Plastic case, laptop metal case and plastic case, home decoration metal, etc., all need to be polished, and the quality of the polishing process directly affects the pass rate and cost accounting of the product. [0003] Pneumatic polishing machines are used on the market. Pneumatic polishing machines are unstable and difficult to realize mechanical automation. There are also electric polishing machines, but the existing electric polishing machines are mainly in the f...

AI Technical Summary

Problems solved by technology

[0003]All pneumatic polishing machines are used on the market. Pneumatic polishing machines are unstable and difficult to realize mechanical automation. There are also electric polishing machines, but the existing electric polishing machines mainly It adopts the form of grinding. It is difficult to grind when grinding relatively hard materials. The grinding time is quite long. Because of the grinding form, the main shaft of the electric polishing machine is made of eccentric double-axis center, which produces The vibration is relatively large, and the centrifugal force is relatively large, so the rigidity of the fixed frame is relatively strict, and the vibration and centrifugal force generated will cause certain damage to the equipment.
