Problems solved by technology

Bearing press-fitting is completed at a separate station, which does not form an assembly line operation. The workpiece needs to be transported one more time, and the sleeve is manually impacted on the bearing up and down to make the bearing press-fit in place. The quality of bearing press-fitting cannot be guaranteed, and the labor intensity is high. Low efficiency; the tightening method of the axle shaft bearing nut: the bearing nut is manually tightened by hand with a hexagonal socket
The tightening of bearing nuts is completed at a separate station, which does not form an assembly line operation. The workpiece needs to be transported one more time. The bearing nuts are tightened by hand with a hollow hexagonal sleeve. The tightening torque of the nuts cannot be guaranteed, resulting in high labor intensity and high work efficiency. Low

Abstract

The invention belongs to the field of automobile assembly, and relates to a complete set of assembly equipment and an assembly process for an automobile drive axle half shaft bearing. It is composed of conveyor line track 1, elastic track 8, workpiece pallet assembly 2, hydraulic press 17, pressure rod 10, balancer 6, constant torque wrench 5 and extended hexagonal sleeve 3, and workpiece pallet assembly 2 is respectively accompanied by elastic track 8 and The movement of the conveyor track 1 is divided into a bearing press-fitting station 18 and a bearing nut tightening station 20, and the elastic track 8 is set correspondingly to the conveyor track 1; the assembly process is divided into a bearing press-fitting process and a bearing nut tightening process. The invention realizes assembly line operation, reduces labor intensity, improves the press-fitting quality of half-shaft bearings and the tightening quality of bearing nuts, and at the same time increases production capacity.

Description

technical field [0001] The invention belongs to the field of automobile assembly, and relates to a complete set of assembly equipment and an assembly process for an automobile drive axle half shaft bearing. Background technique [0002] The press-fitting method of the existing automobile drive axle half-shaft bearings: the bearing is pressed into the half-shaft by a long sleeve sleeve inserted into the half-shaft rod, and the sleeve is manually made to impact the bearing up and down, so that the bearing is pressed into place. Bearing press-fitting is completed at a separate station, which does not form an assembly line operation. The workpiece needs to be transported one more time, and the sleeve is manually impacted on the bearing up and down to make the bearing press-fit in place. The quality of bearing press-fitting cannot be guaranteed, and the labor intensity is high. Low efficiency; the tightening method of the axle shaft bearing nut: the bearing nut is manually tighte...
