Constant force grinding and polishing head mechanism

Abstract

The invention provides a constant force grinding and polishing head mechanism. The constant force grinding and polishing head mechanism comprises a robot connecting flange, a linear motor, balance low-friction air cylinders, a motor flange base, a top connecting flange, an air source connecting head, an outer shell, a floating universal connecting base, a radial constant force floating air ring, aspindle motor and a front fixed flange. The bottom of the robot connecting flange is perpendicularly connected with the linear motor, the two sides of the linear motor are vertically connected with the balance low-friction air cylinders, the bottom ends of the balance low-friction air cylinders are connected with the motor flange base, the upper top surface of the motor flange base is connected with the bottom of the linear motor, and the bottom of the top connecting flange is connected with the outer shell. An annular mounting groove is arranged in the inner wall of an inner cavity of a shell body, the radial constant force floating air ring is arranged in the annular mounting groove, and a plurality of constant force pistons are uniformly distributed on the radial constant force floating air ring. The spindle motor penetrates through the radial constant force floating air ring, one end of each constant force piston abuts against the outer wall of the spindle motor, and the bottom ofthe spindle motor is connected with a grinding head.

Description

technical field [0001] The invention belongs to the technical field of grinding and polishing equipment, and relates to a constant-force grinding and polishing head mechanism. Background technique [0002] At present, most factories use manual or hand-held pneumatic or electric tools for grinding, polishing and deburring operations, which are easy to lead to the rise of defective products, low efficiency and surface roughness of processed products. unevenness, etc. At the same time, high labor costs are required, and a small number of manufacturers have begun to use robots to install ordinary electric or pneumatic tools for automatic grinding. However, due to the irregularity of the rigid grinding and polishing surface of the mechanical arm, it is easy to damage the grinding tool or damage the workpiece due to uneven strength. In the above situation, the automatic constant force floating grinding head is hereby developed. SUMMARY OF THE INVENTION [0003] The purpose of...

AI Technical Summary

Problems solved by technology

[0002] At present, most of the factory's grinding, polishing and deburring operations are mostly done by hand or using hand-held pneumatic or electric tools for grinding, grinding, filing, etc., which will easily lead to an increase in defective products, and the efficiency is low and the surface roughness of the processed products appears. Inhomogeneity etc.
