Description

Technical Field

[0001] The present invention relates to the field of cylinder head processing, and particularly to a processing tooling for facilitating the clamping and positioning of an automotive cylinder head. Background Art

[0002] During the production process of an automotive cylinder head, processing is required, and during processing, the automotive cylinder head needs to be effectively fastened to prevent the cylinder head from slipping during processing, which may affect the processing quality of the cylinder head.

[0003] Generally, the conventional fastening method for an automotive cylinder head usually adopts a connection method of compressing with a screw rod and an ordinary pressing plate. However, this method of fastening the screw rod and the pressing plate with a wrench and a nut is not only prone to problems such as the tightness of the pressing plate after fastening the cylinder head, but also the long-term cooperation of the screw rod and the nut is extremely likely to cause problems such as thread slipping and wear, greatly affecting the fastening effect of the cylinder head and the firmness of the assembly, thus reducing the processing quality of the cylinder head. Moreover, the fastening method using the screw rod and the pressing plate also increases the labor intensity required for the operator to fasten the thread, and it is extremely easy for the operator to have a safety accident during processing. Summary of the Invention
