Inner-hole grinding and polishing device

Abstract

The invention discloses an inner-hole grinding and polishing device which comprises a workpieces. One end of the workpiece is placed into a three-jaw chuck, a grinding pen is disposed in a fixing barrel, a grinding head is arranged at one end of the grinding pen and extends into the inner hole in the workpiece, the other end of the grinding pen is connected with a rotary motor, the rotary motor drives the grinding pen to rotate along the X-axis, the three-jaw chuck is connected with a first motor, the first motor controls and drives the workpiece to rotate along the X-axis through the three-jaw chuck so as to allow the workpiece and the grinding pen to rotate oppositely, a swinging fixing sleeve sleeves the grinding pen, the right side of the grinding pen and the right side of the swinging fixing sleeve are connected with a positioning plate through a fixing pin, the grinding pen and the swinging fixing sleeve are capable of vertically rotating along the fixing pin, the fixing pin is fixed on an automatic feeding workbench, and an X-axis moving mechanism and a Y-axis moving mechanism are arranged between the automatic feeding workbench and the grinding pen. The inner-hole grinding and polishing device has the advantages of high efficiency and good polishing effect.

Description

technical field [0001] The invention relates to the technical field of grinding and polishing, in particular to an inner hole grinding and polishing device. Background technique [0002] Mechanical polishing refers to polishing on a special polishing machine, relying on the relative grinding and rolling action between the extremely fine polishing powder and the grinding surface to eliminate grinding marks, reduce the surface roughness of the workpiece, and obtain a bright and smooth surface. processing methods. In order to meet the surface quality requirements of the workpiece, the minimum roughness of the surface after polishing can reach Ra0.01um by controlling the number of mechanical movements, polishing pressure, abrasive selection, and polishing time control. [0003] Mechanical polishing can be classified into pneumatic and electric types according to equipment; according to the surface characteristics, tools such as cloth wheels and wool sticks can be used to perfor...

AI Technical Summary

Problems solved by technology

At present, for the polishing of the inner hole or deep hole wall, most of them rely on manual operation of the grinding pen to penetrate into the inner hole for polishing. This kind of operation method has the following disadvantages: First, the strength and direction of polishing are not easy to control, and the place where the grinding head does not touch It is easy to miss polishing; second, the workpiece generally does not move during polishing, and the overall uniformity of the inner hole wall cannot be guaranteed; third, the manual labor intensity is relatively large, and the polishing efficiency is slow
