离合器外壳的加工生产线,原来由十一台设备组成,其中大部分是苏联设备,其布置情况如图1所示。在整个加工线中,除623/58转盘铣床、6201/C15鼓形铣床、6H13立式铣床、6H 82Γ卧式铣床、2A473组合机床使用吊车搬运零件外,其余工位都是用人搬上搬下,劳动强度很大(特别是后面两台VR-2摇臂钻床),生产效率低。同志们遵照毛主席关于“中国人民有志气,有能力,一定要在不远的将来,赶上和超过世界先进水平”的教导,决心进行技术改造,改变离合器外壳生产面貌。根据现生产和实际情况,经过充分讨论,决心搞一条自动线。但是,由于零件加工的不连续性,特别是零件从前到后,方向要经过几次改变,对连线很不利。另外,两台摇臂钻床根本无法连入线内。原来机床的夹具也不能通用。为此,同志们决心踢例拦路虎,跨过万重山,要用自制设备代替摇臂钻床,改造原来的夹具,使之适合于自动线。
Clutch shell processing production line, originally composed of eleven devices, most of which are Soviet equipment, the layout shown in Figure 1. In the entire processing line, in addition to 623/58 turntable milling machine, 6201 / C15 drum milling machine, 6H13 vertical milling machine, 6H 82Γ horizontal milling machine, 2A473 combined machine using a crane to carry parts, the remaining stations are employed to move down , Labor-intensive (especially behind two VR-2 radial drilling machine), the production efficiency is low. Comrades, following Chairman Mao’s teachings on “Chinese people have ambition and ability, must catch up with and surpass the advanced world level in the near future”, determined to carry out technological transformation and change the appearance of the clutch housing. According to the current production and the actual situation, after full discussion, determined to engage in an automatic line. However, due to the discontinuity of parts processing, especially the parts from front to back, the direction to go through several changes, the connection is not good. In addition, the two radial drilling machine can not even enter the line. The original machine tool fixture can not be universal. To this end, the comrades determined to kick the blockade Tiger, across the million mountains, to use homemade equipment instead of radial drilling machines, transformation of the original fixture, making it suitable for automatic lines.
