一、改装前的情况我厂水泥设备分厂有一台3.4m立车,专门用来加工水泥窑上的大型球面瓦和球面轴承。过去曾为该机床设计了一套机械式连杆滑板机构加工球面。该装置的缺点是悬臂太长,吃刀不能太深,加工效率低,表面粗糙度高,精度也低。二、改装时遇到的两个主要问题1.该立车的精度极差,机床经多年使用后严重磨损,导轨,丝杠和齿轮等各处间隙很大,吃刀时滑枕上冲达2mm,还有爬行现象。
First, the situation before the conversion I plant cement equipment factory has a 3.4m vertical lathe, dedicated to processing large-scale spherical kiln and spherical bearings on the kiln. In the past, a mechanical connecting rod skateboarding machine was designed for the machine tool to machine the spherical surface. The disadvantage of the device is that the cantilever is too long, the knife can not be too deep, the processing efficiency is low, the surface roughness is high and the precision is also low. Second, the two major problems encountered in the conversion 1. The accuracy of the car was very poor, after years of serious wear and tear of the machine, rails, screws and gears and other parts of the gap is large, eating ram Rushed 2mm , There are crawling phenomenon.
