Engine cylinder head end face drilling and milling method

Abstract

The invention discloses an engine cylinder head end face drilling and milling method including a clamping procedure of a cylinder head. A special clamp is used in the clamping procedure, traditional long stripe plates are replaced by supporting nails, so that the contacting surface of the cylinder head during clamping is reduced greatly, and the problem of excessive large flatness caused by excessive large positioning face by traditional clamping is reduced greatly, accurate clamping of the cylinder head can be realized, and a solid foundation is laid for reducing unnecessary system errors in the drilling and milling procedure of two end faces of the cylinder head; the clamp is provided with a gas detecting device, and fitting leakproofness between the supporting nails and the cylinder head can be detected timely to guarantee reliable clamping; the clamp is simple in structure, usage and operation are facilitated, and workers for processing the products can work and operate without training, so that processing efficiency of the cylinder head can be improved.

Description

technical field [0001] The invention relates to a method for manufacturing a cylinder head, in particular to a drilling and milling method for an end face of an engine cylinder head. Background technique [0002] At present, during the machining process of the cylinder head of the automobile engine, the drilling and milling of the two ends of the cylinder head is a very important process in the process of the cylinder head, and its machining accuracy will directly affect the product quality of the engine cylinder head, especially the fixture The quality of the impact on the machining accuracy. Due to the complex structure of the engine cylinder head, the drilling and milling process of its two ends is very difficult, the main part of which is the tooling problem. In the general processing process, the universal combined fixture on the machine tool is often used to realize the clamping of the tooling. The cylinder head is placed on two long strips in the machine tool, and th...

Problems solved by technology

Using this clamping method requires the operator to have very skilled technology, and due to the complexity of the structure of the automobile engine cylinder head, it takes a lot of time for the operator to select and install the general combination fixture, which affects the processing efficiency of the cylinder head. It also caused unnecessary impact, and because the large reference plane of the long strip caused the problem that the plane of the positioning surface was too large, so that a large system error was generated, and the yield of the processed cylinder head decreased at this time
