Pressure adjustment type abrasive belt grinding device

Abstract

The invention discloses a pressure adjustment type abrasive belt grinding device which consists of a transmission device, a pressure adjustment device and a grinding and polishing pressure control system, wherein the transmission device consists of a body, a power input shaft, a bearing, a first bevel gear, a second bevel gear, a gear shaft, a drive wheel, an abrasive belt, a second body, an abrasive belt supporting wheel and an abrasive belt grinding and polishing wheel, wherein the pressure adjustment device consists of a thin film air cylinder, an abrasive belt small main shaft and a supporting wheel frame; the grinding and polishing pressure control system consists of a force sensor, a pressure servo valve and an air source; an external electric motor is connected with the power input shaft and drives the drive wheel of the transmission device to rotate, so that the abrasive belt moves to grind and process a curved surface of a workpiece; the thin film air cylinder of the pressure adjustment device can drive the abrasive belt small main shaft to move forwards and backwards; and when the grinding pressure is changed, the force sensor transmits a pressure signal to the pressure servo valve, successively pushes the thin film air cylinder to act and drives abrasive belt small main shaft to move forwards and backwards so as to realize the pressure adjustment control. With the adoption of the pressure adjustment type abrasive belt grinding device, the isopiestic grinding and processing of the curved surface can be realized while the speed is adjusted.

Description

technical field [0001] The invention relates to a grinding device, in particular to a pressure-regulating abrasive belt grinding device. Background technique [0002] Commonly used micro-grinding devices can adjust the speed, but do not have the function of pressure regulation. When processing curved surfaces, equal-pressure processing is often required. Therefore, commonly-used micro-grinding devices cannot meet the requirements of such pressure grinding on curved surfaces. Contents of the invention [0003] The purpose of the present invention is to solve the problem that the commonly used micro-grinding device cannot adapt to the pressure grinding requirements of curved surfaces, and to provide a pressure-regulating abrasive belt grinding device, which can realize equal grinding while adjusting the speed. Pressure grinding, through the synchronous control of force and displacement and the use of displacement compensation technology, achieves the purpose of automatically...
