Processing apparatus for initial cracking tank for engine connecting rod

The present invention relates to an engine connecting rod splitting notch processing equipment. Object of the present invention is to overcome the initial link in the presence of the cleavage groove machining quality and machining precision instability problem, an engine connecting rod initial cleavage groove machining apparatus which includes host and workholding table. The host composed as follows: host rack z-axis and x-axis direction are provided with guides and the slider, the slider on the linear motion guide rail; the workpiece clamping table in the following manner: workbench can be used with a linear motion along the y-direction slider with three rotating cylinders pressing on the slider, and a replaceable workpiece positioning plate. Processing equipment using initial cleavage groove on both sides of the present invention has a groove width, depth uniform, high dimensional accuracy, significantly improve the quality of the fracture surface, avoid the fracture surface dregs, big hole deformed super poor.
