Abstract

The invention discloses a workpiece tightening all-purpose rotation stop mechanism and a main reduction gear rotation stop and tightening mechanism. The main reduction gear rotation stop and tightening mechanism comprises a twisting assembly used for twisting multiple screws on a main reduction gear at the same time, and further comprises a rotation stop mechanism. The rotation stop mechanism comprises a rotation stop locating block, a rotation stop pin and a spring. A rotation stop pin motion hole is arranged in the rotation stop locating block, the rotation stop pin is kept in the rotation stop pin motion hole, and the spring presses the rotation stop pin bias so that the rotation stop pin can have the tendency of stretching outwards. The rotation stop pin is used for allowing the headsof the screws to stretch into rotation stop pin motion hole when the screws are already twisted in screw holes in the main reduction gear so as to achieve rotation stop on the main reduction gear. According to the workpiece tightening all-purpose rotation stop mechanism and the main reduction gear rotation stop and tightening mechanism, rotation stop is achieved through bolt via holes and bolts needing to be assembled and tightened, quite wide flexibility is achieved, the structure is compact, and the scheme is reliable.

Description

technical field [0001] The invention relates to the field of assembly of automobile gearboxes, in particular to a main reduction gear anti-rotation screw mechanism, and also relates to a universal anti-rotation mechanism for workpiece tightening. Background technique [0002] The gearbox is an important component of the automobile transmission system. The main reducer is the main part of the automobile transmission system to reduce the speed and increase the torque. The bevel gear and bevel gear of the gear change the transmission direction of the power. [0003] Assembling the main reduction gear is one of the most important processes in the assembly process of the automobile gearbox. The quality of its assembly directly affects the overall performance of the gearbox. Figure 1a to Figure 1c It is a schematic diagram of the assembly assembly of the main reduction gear. The main reduction gear 100 is connected with the main reduction gear 200 (differential) through bolts 300...
