Adjustable clamp for machining crankshaft connecting rod journal

The machining of the crankshaft connecting rod journal is one of the key processes in crankshaft machining. In the past, the tool for machining the third and fourth connecting rod journals of the crankshaft designed by our factory can only process one type of crankshaft. Not only the economic benefits are poor, but also the production cycle is long. At the same time, because the fixtures are cumbersome, it takes time and effort to replace the tooling, and it is easy to damage the equipment. To this end, we have designed an adjustable fixture that works well. First, the fixture structure is shown in Figure 1. The specific end of the clamp is connected with the crankshaft lathe, and the other end is provided with a fixed V-shaped block 2. The adjustable V-shaped block 5 supporting the main journal can be axially along the groove of the bottom of the clamp. Move to adapt to processing
