Tightening assembly, tightening machine, motor assembly and vehicle differential assembly device

Abstract

The invention belongs to and relates to an automatic assembly technology for a vehicle differential mechanism and a motor, and discloses a tightening assembly, a tightening machine, a motor assembly and a vehicle differential mechanism assembly device. Comprising four movable seats of a tightening assembly, the movable seats are installed in cross-shaped grooves of corresponding cross-shaped groove substrates respectively, and the four movable seats synchronously slide along the cross-shaped grooves of the cross-shaped groove substrates; a curve type rotary driving plate is arranged on one side face of the moving seat, and curve type clamping grooves which correspond to the moving seat and are uniformly distributed in the circumferential direction are formed in the curve type rotary driving plate; the rotating center axis of the curve type rotation driving plate coincides with the cross groove center axis of the cross groove base plate. A tightening gun is mounted on the moving seat; a limiting column at the lower end of the moving seat is positioned at the overlapped part of the curve type clamping groove and the cross groove of the cross groove substrate; the four linear clamping grooves of the curve type rotary driving plate are improved into the four curve type clamping grooves, and the problem that the differential mechanism four-shaft tightening machine is small in variable pitch range, and consequently the number of covered varieties is small is effectively solved.

Description

technical field [0001] The invention relates to the automatic assembly technology of a vehicle differential and an electric motor, in particular to a tightening assembly, a tightening machine, an electric motor assembly and a vehicle differential assembly device. Background technique [0002] In the field of vehicle differential and motor assembly and manufacturing, tightening bolts is an extensive assembly requirement. However, the number of bolts that need to be tightened in the assembly and manufacture of vehicle differentials and electric motors is large, the size of different varieties of products varies greatly, and the working time is long. The traditional four-axis screwdriver has a small range of pitch changes, resulting in fewer varieties of coverage. SUMMARY OF THE INVENTION [0003] In view of this, the present application provides a tightening assembly, a tightening machine, an electric motor assembly and a vehicle differential assembly device, thereby effect...
