在小批生产十六吨液压汽车起重机汽车底盘的前、中、后桥左右半壳时(见图1),内圆弧要求公差±0.1,光洁度▽7,与孔同心度0.03。过去,在 C630车床上用样板刀加工时,很难保证质量。后经过如下改进,解决了质量关键,并提高效率达四倍:如图2所示,在 C630车床的刀架上,装一套切削内圆弧工具。调整刀头中心使之与回转中心对正、刀尖对正端面。加工时,反时针摇动尾架,因尾架卡头夹住系在刀盘上的钢丝绳的末
In small batch production of 16 tons of hydraulic truck crane chassis before and after the bridge when the half-shell (see Figure 1), the arc required tolerance ± 0.1, finish ▽ 7, 0.03 with the hole concentric. In the past, it was hard to guarantee quality when machining with a prototype knife on a C630 lathe. After the following improvements to solve the quality key, and improve efficiency up to four times: As shown in Figure 2, in the C630 lathe turret, installed a cutting tool within the arc. Adjust the center of the cutter so that it is aligned with the center of rotation and the nose is aligned. Processing, shaking the tailstock counterclockwise, because the end of the tailstock clamping chuck tied to the end of the wire rope
