我厂加工的汽车前轴规格比较多,每种规格前轴弹簧座沉孔都在摇臂钻上钻削。由于每种规格的前轴都需专用的夹具,这就提高了工件的成本,并延长了工件的制造周期。为此我们对本厂加工的汽车前轴进行了分析,见表1。通过表1可以看出,这些前轴弹簧座之间的距离都接近或者相等,这样就可以做一个通用可调夹具,加工哪种规格的前轴就换上哪种规格的钻模板,很方便,并可以降低夹具的制造成本。

I plant the processing of the vehicle front axle specifications more, each specification shaft spring seat counterbore drilling in the rocker drilling. Because each specification of the front axle requires a dedicated clamp, this increases the cost of the work piece and prolongs the manufacturing cycle of the work piece. For this reason, we have analyzed the factory front axle of our factory, as shown in Table 1. It can be seen from Table 1 that the distances between these front axle spring seats are both close to or equal to each other so that a universal adjustable clamp can be made and which specifications of the front axle are machined to facilitate drilling , And can reduce the manufacturing cost of the jig.
