Description

Technical Field

[0001] The utility model relates to the technical field of reducer processing fixture equipment, in particular to a helical gear reducer processing fixture. Background Art

[0002] A reducer is an independent component consisting of a gear transmission and a worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. Reducers are generally used for low-speed and high-torque transmission equipment. The power of an electric motor, internal combustion engine or other high-speed running power is reduced by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft. The gear shaft is the main component of the reducer to ensure the safety and stability of the reducer's movement. At present, for the hardened gear shaft after carburizing and quenching, the clamping when machining the tooth surface on the worm gear grinding machine generally adopts the external circle clamping type or the top top clamping center hole type pre-tightening to ensure the tooth surface accuracy. The helical gear reducer machining fixture is a tool designed for machining helical gear reducers. It is used to fix and position the reducer parts to ensure the accuracy and efficiency of the machining process.

[0003] However, when the reducer housing in the prior art is processed on a machine tool, it needs to be positioned and clamped. The existing reducer housing clamp usually uses a clamping block and bolts to clamp the bottom of the reducer. When in use, the clamping blocks located at the four corners of the bottom of the housing need to be tightened separately. The operation is relatively complicated, resulting in low work efficiency. Utility Model Content
