Description

Technical Field

[0001] The invention relates to the technical field of automobile manufacturing, and in particular to a gearbox turning machine anti-falling device. Background Art

[0002] During the assembly process of the gearbox housing and gear shaft transfer line, the gear shaft housing assembly with meshed gears needs to be flipped by the gearbox flipper and then transferred to the assembly line for assembly. The current method is to use the gearbox flipper's claws to directly clamp the housing ear on the gear shaft housing assembly to flip the housing and transfer it.

[0003] Since the gear shaft to housing component is provided with a V-block, which contains four locating pins, these four locating pins will be pulled out and fall to the ground when the clamps clamp the housing ears to turn the box over and transfer the line. On the one hand, employees may be easily tripped by the locating pins that fall to the ground, posing a safety hazard. On the other hand, the locating pins may be worn out and become scrapped, causing the gear shaft to housing component to need to be disassembled and reassembled, affecting the production rhythm and assembly quality of the assembly line.
