我厂制造50AT轨整形模时,遇到腰模这一零件上的螺旋面加工问题.这个螺旋面长度为200mm,两端分别联接着斜度为1:9和1:4的两个斜面(见图1)。该螺旋面加工比较困难,为此我们改装了B665牛头刨床.解决了腰模螺旋面的加工问题. 一、改装如图2所示。取下平口钳下面的底座。并为其设计一个可以回转的底座。可转底座的翻板1上面做成斜度为1:9的斜面,通过轴2与底座3铰接,底座3则安装在工作台上.另外,将水平进给丝杠铣出一长键
I plant manufacturing 50AT rail shaping die, the problem encountered in this part of the spiral surface of the spiral processing of the helical length of 200mm, at both ends were connected with a slope of 1: 9 and 1: 4 of the two bevels (see picture 1). The spiral surface processing more difficult, for which we converted the B665 shaver planing. Solve the problem of processing the waist mode spiral surface. Remove the base under the jaws. And design a swivel base for it. Turn the base of the flap 1 made of a gradient of 1: 9 above the ramp through the shaft 2 hinged to the base 3, the base 3 is mounted on the workbench.In addition, the horizontal feed screw milling a long key
