[0002] The automobile engine camshaft bearing cap (also referred to as the bearing cap) is a metal automotive component. It is an axisymmetric strip-shaped component with positioning holes on both sides of the bottom. The upper, lower, left, and right sides of the automobile engine camshaft bearing cap blank have machined surfaces and machined holes.

[0003] In the process of processing automobile camshaft bearing caps, a combination fixture commonly used on machine tools is often used to achieve tool clamping. During clamping, the bearing cap is placed on two long strips in the machine tool, and then the bearing cap is pressed with a pressure plate with a coil spring. Then the machine tool is started to perform rough and fine processing on the bottom surface of the bearing cap. This not only requires the operator to have very skilled technology, but also the camshaft bearing cap is relatively small and difficult to clamp, which increases the complexity of clamping the automobile camshaft bearing cap. In addition, the large reference surface of the long strip causes the flatness of the bearing cap positioning surface to be too large, resulting in a large system deviation, which easily affects the processing accuracy of the automobile camshaft bearing cap. For this reason, the utility model proposes a new solution. Utility Model Content
