[0002] The reducer tooling provides standardized installation, debugging and maintenance processes, making the operation more standardized and efficient, and reducing errors and delays caused by human factors; the tooling provides stable support for the reducer, preventing equipment damage or safety accidents caused by vibration or impact. The tooling design often takes into account the installation position and fixing method of the reducer. Through precise positioning and fixing devices, the reducer can be quickly installed at the designated position, saving a large amount of installation time; the use of the tooling can reduce the mechanical impact and vibration of the reducer during transportation, installation and use, thereby extending the service life of the reducer and reducing the maintenance cost.

[0003] Traditional reducer tooling usually ensures the precise position of the reducer during installation through positioning pins, positioning holes, etc., and uses bolts and nuts to fix the reducer to the tooling; or fixes the reducer to the machine base through four anchor bolts and fixes it to the machine base through washers; this fixing method is simple, but it is suitable for occasions where the reducer power is relatively small, and it is not stable enough for high-power reducers and has low fixing accuracy.

[0004] A "special tooling for the hub reducer housing of Beiben" disclosed in the Chinese patent literature, with the publication number CN207464703U, includes a square limiting ring, support columns evenly distributed in the circumferential direction of the main structure, and bolt holes fixed to the lathe. A high fixing plate and a low fixing plate are fixed between the support columns, and the high fixing plate and the low fixing plate are arranged alternately. The half shaft holes below the reducer housing are fixed through a pressing block and a positioning pin, and the limiting ring above the tooling is fixed above. Through simultaneous limiting of the upper and lower sides, however, the machining features of this tooling design are far from the positioning surface, and the workpiece is extremely prone to vibration and lacks stability.
