我厂去年试制Y315M电机,因缺少大机座车削设备,只好在维修车间的一台CY5112立车上进行加工。用这台单柱工作台移动立车,车削Y315M机座,存在两个问题:(1)如利用机床回转刀台下面的小四方刀台车削,由于机床回转刀台太大。不能进入机座内圆,无法进行车削。(2)如在四方刀台刀杆孔安装长刀杆车削,该机床垂直刀架距工作台最大距离为1200mm,Y315M机座毛坯长度为723mm,长刀杆需要长度为620mm,两者共长为1343mm,再加上回转刀台和夹盘爪厚度,远远超出该机床加工范围,所以,安装长刀杆也无法进行车削。为此,我们决定对CY5112立车刀架进行改进,以达到一部立车既能车削大型号机座,又能担任大的维修工件车削的目的。我们对该机床刀架作了如下改进:(1)将回转
Last year, our factory trial Y315M motor, due to the lack of large machine turning equipment, had to repair a CY5112 workshop car vertical machining. With this single-column table moving vertical lathe, turning Y315M machine base, there are two problems: (1) If the use of rotary table under the rotary cutter small square knife turning, rotary table because the machine is too large. Can not enter the machine circle, can not be turning. (2) If the cutter bar hole in the Sifang Daogan long bar turning, the vertical distance between the vertical turret and the table 1200mm, Y315M base length of 723mm blank, long arbor need length 620mm, the total length of the two 1343mm, together with the rotary table and chuck claw thickness, far beyond the scope of the machine processing, so the installation of long arbor can not be turned. For this reason, we decided to improve the CY5112 vertical turning tool holder so as to achieve the goal of turning a large-size machine base while turning a large maintenance workpiece. We made the following improvements to the machine tool holder: (1) will be rotated
