Machining long taper shaft automatic device

Our factory processes large roller cone shaft (Fig. 1), the axle weight is 4.5t, the total length is 4980mm, the cone length is 3600mm, the taper is 1:30, the material is 45 steel, 220~250HB. Our factory has no special equipment for car taper. Therefore, the automatic cone taper device is inst.......

New high torque impact electric wrench

In the repair and assembly of the vehicle, we have developed the P3B-42 new high-torque impact type electric wrench (see picture), which is very effective. It is the largest one of the domestic impact type electric wrenches. It is the ideal tool for disassembling high-strength, high-torque thr.......

Machining of semi-axle

In the past, we used the semi-axle (Fig. 1) to cut the roughed bush into two halves, and then finish it after soldering, which is inefficient. Now we improve the fixture (Fig. 2) and the new process, eliminating the soldering process, improving the efficiency and reducing the cost. The new pro.......

Research and implementation of instrumental and practical CAPP system

Because the process design activities are highly integrated, empirical and creative thinking activities, but currently in the computer simulation of human thinking and artificial intelligence research is still only in a simple, regular or even formatted analog logic thinking stage, blindly The.......

New method for thin plate drilling

In machining, it is often drilled on thin plate parts below 1.5 mm. When machining with ordinary twist drill, due to the poor rigidity of the thin plate parts, the axial force is pressed downwards in the drilling, and the cutting torque is twisted and deformed; the elasticity of the parts and .......
