Manipulator composite grinding tool for thin-wall part

Abstract

The invention provides a manipulator composite grinding tool for a thin-walled part, and belongs to the field of grinding and polishing. The manipulator composite grinding tool is characterized by comprising a bracket, a base, a grinding device, a magnetic grinding device and a control device; the bracket is used for being connected with a manipulator, the base is mounted on the bracket in a lifting manner; the grinding device is arranged on the base and is provided with a grinding part for polishing the thin-wall part from one side of the thin-wall part; the magnetic grinding device is arranged on the base and provided with a rotatable magnet assembly arranged on one side of the thin-wall part and magnetic abrasive particles arranged on the other side of the thin-wall part, and the magnetic abrasive particles are matched with the rotating magnet assembly to be used for grinding the other side of the thin-wall part; and the control device is used for controlling double-sided grinding of the grinding device and the magnetic grinding device. According to the grinding tool, the normal pressure on the thin-wall part is reduced, the stress deformation in the grinding process is reduced, the design difficulty and the manufacturing cost of a thin-wall part clamp are reduced, and the process efficiency is improved.

Description

technical field [0001] The invention belongs to the field of grinding and polishing, and in particular relates to a manipulator composite grinding tool for thin-walled parts. Background technique [0002] Thin-walled parts are widely used in aerospace and other fields, such as aircraft skeletons, skins and blades, etc., which have many advantages such as small weight, high specific strength and good mechanical properties. However, due to the large size of thin-walled parts, complex structure, poor rigidity, and high precision requirements, high-quality processing of thin-walled parts has always been a bottleneck and a problem of widespread concern in the industry. In order to overcome the problems in the manufacturing process of thin-walled parts, experts and scholars in related fields at home and abroad have been working on related research work. In particular, certain progress has been made in automated flexible manufacturing technology, and breakthroughs have been made i...

Problems solved by technology

[0006] However, when grinding thin-walled parts, due to its complex structure, poor rigidity and high requirements for controlling the wall thickness during the grinding process, the existing floating grinding It is difficult for the device to guarantee its grinding quality

On the one hand, the floating of the grinding device is not easy to control, which may easily cause over-grinding or under-grinding when the grinding piece encounters a special-shaped structure during the grinding process, resulting in poor grinding quality and accuracy; on the other hand, there is a hysteresis error in the floating grinding device, which acts on thin-walled parts The normal pressure is easy to cause the processing deformation of the workpiece
