Clamping mechanism and clamping method for automobile engine cylinder head

Abstract

The invention relates to a clamping mechanism and a clamping method of a cylinder head of an automobile engine. The clamping mechanism includes a mechanism frame and a shelf, the shelf is movably arranged in the mechanism frame, and the side wall of the mechanism frame is fixedly connected with a support A side plate, a workbench is fixedly arranged on the shelf, and two side position limiting plates are symmetrically fixedly connected to the workbench; in the present invention, by co-extruding and fixing the side wall and the top of the engine cylinder head, In this way, when the engine cylinder head is clamped and fixed, the engine cylinder head can be prevented from being extruded from the top of the fixture, so that the engine cylinder head can be fixed more firmly, and then the effective processing effect on the engine cylinder head can be achieved. At the same time, In the present invention, the structural design is reasonable, and the control of the top and side clamping mechanisms can be realized through a single power source, so that the effect of reducing production costs can be achieved when the engine cylinder head is fixed firmly. Therefore, the present invention The setting is more in line with market demand.

Description

technical field [0001] The invention relates to the technical field of engine cylinder head processing, in particular to a clamping mechanism and a clamping method for an automobile engine cylinder head. Background technique [0002] The cylinder head is mounted on top of the cylinder block, sealing the cylinder from above and forming the combustion chamber. It is often in contact with high-temperature and high-pressure gas, so it bears a large thermal load and mechanical load. The accuracy of the engine cylinder head hole position plays a vital role in engine assembly. If the hole position deviates, the engine cylinder head needs to be removed for reprocessing. In the process of processing, the cylinder head needs to be fixed on the fixture. The existing fixtures fix the cylinder head from the side wall and align with pins. However, in the process of clamping the side wall of the cylinder head, it is easy to make The cylinder head is extruded from above. At the same time,...

Problems solved by technology

In the process of processing, the cylinder head needs to be fixed on the fixture. The existing fixtures fix the cylinder head from the side wall and align with pins. However, in the process of clamping the side wall of the cylinder head, it is easy to make The cylinder head is extruded from above. At the same time, the existing fixture adopts multiple power sources to control different fixtures at the same time. This not only has the problem of inconvenient operation, but also leads to investment in production costs. In order to solve the above problems, the present invention In, a clamping mechanism for the cylinder head of an automobile engine is proposed
