Abstract

The invention discloses a pressure and tension combined-control abrasive belt grinding device and a using method thereof. The device comprises a contact wheel assembly, a first air cylinder, a drivingwheel assembly, a tensioning wheel assembly, a second air cylinder, a second idler wheel assembly and an abrasive belt, wherein the contact wheel assembly is connected with the extending end of an air cylinder push rod of the first air cylinder, and the first air cylinder is used for adjusting the contact pressure of the contact wheel assembly; the tensioning wheel assembly is connected with theextending end of an air cylinder push rod of the second air cylinder, and the second air cylinder is used for adjusting the tensioning force of the tensioning wheel assembly; and the abrasive belt sequentially passes through a driving wheel of the driving wheel assembly and a tensioning wheel of the tensioning wheel assembly, the second idler wheel of the second idler wheel assembly and the contact wheel of the contact wheel assembly and is tensioned. According to the pressure and tension combined-control abrasive belt grinding device, the contact wheel assembly and the tensioning wheel assembly are controlled to complete corresponding displacement, and the influence of changes of the normal grinding pressure on the tension is eliminated; and the grinding force of the grinding process is kept constant, so that the vibration in the grinding process is effectively reduced, and the quality of the machined surface and the service life of the abrasive belt are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of abrasive belt grinding, and in particular relates to an abrasive belt grinding device with joint control of pressure and tension force and a use method thereof. Background technique [0002] With the development of industrial processing technology and the continuous improvement of product precision, modern machining is generally developing in the direction of high precision and high efficiency. High precision is aimed at continuously improving product manufacturing accuracy and reducing surface roughness, such as precision and ultra-precision machining; high efficiency is mainly achieved through strong force and high efficiency. CNC abrasive belt grinding is a kind of elastic grinding, which is not easy to deform the workpiece. It is called "cold state" grinding. After grinding, the surface of the workpiece is not easy to be burned. It is one of the precision and ultra-precision machining technologies. ...
