Automatic tightening and mark rolling inspection and assembly system of spline nuts of rear axle main speed reducer

Abstract

The invention discloses an automatic tightening and mark rolling inspection and assembly system of the spline nuts of a rear axle main speed reducer. The automatic tightening and mark rolling inspection and assembly system of the spline nuts of the rear axle main speed reducer comprises a positioning mechanism, tightening devices, a moving device, a mark rolling inspection driving device and a matched servo control system. The positioning mechanism is used for installing and fixing the main speed reducer, the tightening device is used for providing torque for the spline nuts on the two sides of the main speed reducer, and the moving device used for driving the tightening device to move along the axis direction of the spline nuts; the main speed reducer is arranged on the positioning mechanism, the tightening device is provided with two groups, the tightening device are symmetrically arranged on the two sides of the main speed reducer, and the tightening device can be coaxially connected with the spline nuts on the two sides of the main speed reducer respectively; each tightening device is provided with the moving device, and the tightening device and the moving device are arrangedthe working table, and output end of the mark rolling inspection driving device is connected with a connecting flange of the driving gear of the main speed reducer. The automatic tightening and mark rolling inspection and assembly system of the spline nuts of the rear axle main reducer has the advantages of being high in automation degree, high in precision, fast and reliable, intelligent and controllable, greatly improving the working efficiency and the assembly precision, and saving the labor cost.

Description

technical field [0001] The invention relates to the technical field of assembling the main reducer of the rear axle of an automobile, in particular to an assembly system for the automatic tightening and rolling inspection of the flower nut of the main reducer of the rear axle. Background technique [0002] On the assembly line of the main reducer of the rear axle of the automobile, the flower nuts installed at both ends of the half shaft gear of the main reducer need to be loaded with a certain torque at the same time for pre-tightening; at the same time, the position of the flower nut can be adjusted to adjust the gear clearance; After the nuts are tightened, it is necessary to manually turn the connecting flange of the main gear to make the gear pairs mesh dynamically, so as to achieve the purpose of contact impression rolling inspection. These steps are all done manually by experienced assembly masters. However, due to the bulky and complex shape of the main reducer, it i...
