AI Technical Summary

Technical Problem

During the assembly of the engine cylinder head, the difference in the coefficient of thermal expansion of the lightweight aluminum alloy materials leads to high requirements for assembly precision and makes it difficult to adjust to the optimal installation angle, resulting in sealing and assembly precision issues.

Method used

An auxiliary device including an angle adjustment mechanism, a rotation positioning mechanism, and a lifting mechanism was designed. The cylinder head angle, direction, and height are precisely adjusted by driving the slide rod and threaded rod with a servo motor, and the cylinder head position is stabilized by using a clamping plate and a slot structure.

Benefits of technology

It enables rapid adjustment of cylinder head angle, direction and height, improves assembly accuracy, adapts to the operating needs of workers of different heights, and reduces the difficulty of manual adjustment and assembly cost.

Abstract

This utility model provides an auxiliary device for engine cylinder head assembly, relating to the field of engine assembly technology. The auxiliary device includes an angle adjustment mechanism, which comprises a support frame rotatably connected to two symmetrical first rotating discs. The device adjusts the engine cylinder head assembly angle by placing it between the two symmetrical clamping discs, then rotating the two symmetrical second rotating discs to bring the two symmetrical first sliding rods closer together, thereby clamping the engine cylinder head between the two symmetrical clamping discs. By rotating the engine cylinder head up and down, the assembly angle can be adjusted. Finally, rotating the two symmetrical third rotating discs causes the two symmetrical second threaded rods to press against and fix the first rotating discs, thus achieving the purpose of quickly adjusting the engine cylinder head assembly angle.
