Problems solved by technology

[0002] When the cycloidal wheels are finely ground, the side holes of the center hole machine are used for positioning at first, and the cycloidal wheels are stacked relative to each other. The positioning of the side holes of the upper and lower cycloidal wheels is different, and qualified products are produced after repeated roughing and finishing. , but the tooling used in this method has a partition in the middle, the middle mandrel is long, and the shape and position tolerances such as radial runout are difficult to guarantee, and its production process is complicated, and the teeth need to be aligned every time. The efficiency is low and the processing quality cannot be guaranteed.

Abstract

The invention relates to a cycloidal gear grinding tool that comprises a base, and a supporting plate, a middle liquid expansion mandrel, a liquid adding groove, a plunger, a hydraulic expansion sleeve, a conical surface gasket, a spherical surface gasket, a round nut, a tool pressing plate, a fixing nut, a convex ring, a side hole mandrel expansion sleeve and a mandrel pressing plate are arrangedon the base. When in use, two cycloidal gears are oppositely placed, so cycloidal gear teeth can be conveniently machined, and the problems that alignment of the teeth is difficult and the like in arelative stacking placement mode are solved; meanwhile, the hydraulic expansion sleeve deforms due to liquid pressurization, and the positions of the two cycloidal gears are more accurate due to the special-shaped side hole mandrel expansion sleeve; and finally, due to pressing of the tool pressing plate, the angle deviation is smaller when the cycloidal gear is machined, and the machining qualityis effectively improved.

Description

technical field [0001] The invention relates to the technical field of cycloid wheel processing, in particular to a gear grinding tool for cycloid wheels. Background technique [0002] When the cycloidal wheels are finely ground, the side holes of the center hole machine are used for positioning at first, and the cycloidal wheels are stacked relative to each other. The positioning of the side holes of the upper and lower cycloidal wheels is different, and qualified products are produced after repeated roughing and finishing. , but there is a partition in the middle of the tooling used in this method, the middle mandrel is long, and the shape and position tolerances such as radial runout are difficult to guarantee, and the production process is complicated, and the teeth need to be aligned every time. The efficiency is low and the processing quality cannot be guaranteed. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and pr...
