一、磨床工作台纵向往复运动油缸、活塞磨损后加O型密封圈恢复运动精度磨床经多年使用后,工作台纵向往复运动的油缸与活塞表面均有磨损,间隙过大,油泄漏,使工作台运动出现不规则、爬行和冲击等现象,严重地影响产品的精度。一般是更换或电镀加大活塞的外径尺寸,使之重新与油缸配合,间隙保证在0.04～0.09mm之间,其加工周期长、加工精度高,需要重新配研等。现介绍一种简捷的维修方法,可解决上述问题。
First, the vertical reciprocating grinding machine table cylinder, piston wear plus O-ring to restore motion accuracy Grinder after years of use, the longitudinal reciprocating workbench cylinder and piston surfaces are worn, the gap is too large, the oil leaks, so that work Taiwan movements appear irregular, crawling and impact and other phenomena, seriously affecting the accuracy of the product. Generally replace or electroplating to increase the outer diameter of the piston size, make it with the cylinder again, the gap is guaranteed between 0.04 ~ 0.09mm, the processing cycle is long, high precision, the need to re-research and so on. Is now introduced a simple method of maintenance, to solve the above problems.
