Abstract: In order to improve the assembly accuracy of the combined camshaft of the engine and ensure the accuracy of the phase angle of the camshaft with the same name of each cylinder, a convenient assembly device of the combined camshaft is designed and made, and the practical application is carried out. The application results show that the assembly device can assemble the camshaft quickly and accurately. The phase angle adjustment operation of each cylinder is simple, convenient, fast and accurate. The phase angle of each cylinder with the same name and exhaust CAM adjusted by the assembly device meets the requirements of use. After the camshaft is installed, the engine performance is stable and reliable.
