Embodiment Construction

[0016] Such as figure 1 with figure 2 As shown, the present invention includes a thin-walled ring gear fixing part, which is a cylindrical structure, and an upper groove is arranged in the cylindrical structure, and the size of the upper groove and the thin-walled ring gear to be processed The size of the ring gear is the same, but the depth is greater than the thickness of the thin-walled ring gear. This design purpose is to prevent the M value of the tool end from getting out of control. At the same time, it can also precisely control the matching size between the outer circle of the part and the inner hole of the tooling. In addition, there are chamfers on both sides of the top of the upper groove. The purpose of the chamfers is to better position and place the thin-walled ring gear to be processed. In addition, there is a groove inside the bottom of the upper groove. The purpose of the groove is to make the placement of the workpiece into the fixture more precisely cont...

Abstract

The invention provides a device for machining thin-walled gear ring broaching. The device for machining the thin-walled gear ring broaching comprises a thin-walled gear ring fixation part and a connection fixation block which connects a thin-walled gear ring fixation device and an operation platform. The thin-walled gear ring fixation part is of a cylindrical structure and an upper groove matched with a thin-walled gear ring is formed in the thin-walled gear ring fixation part. The depth of the upper groove is larger than the thickness of the thin-walled gear ring to be machined. A groove is formed in the bottom. The upper portion of the connection fixation block of the operation platform is provided with a protruding portion matched with the bottom of the thin-walled gear ring fixation part. The connection fixation block further comprises a through hole. By means of the technical scheme, the problems of the thin-walled gear ring that deformation is excessively large in a broaching process, plastic deformation is caused and broaching taper is caused by plastic deformation are solved, broaching stress and production of taper can be effectively controlled, and the subsequent heat processing technology is more convenient to perform. Meanwhile, the device for machining the thin-walled gear ring broaching has the advantages of being simple in structure, convenient to maintain, low in machining cost and the like.

Description

technical field [0001] The invention belongs to the field of processing broaching holes of thin-walled ring gears, and in particular relates to a device for processing broaching holes of thin-walled ring gears. Background technique [0002] Due to its unique characteristics and strict technical requirements, the thin-walled ring gear has always been a difficult point in processing. In the actual production process, it often occurs that the thin-walled ring gear is deformed too much during the hole drawing process, resulting in plastic deformation, and the deformation is large and uneven after subsequent heat treatment, and the heat treatment deformation of the part is basically uncontrollable. Contents of the invention [0003] The problem to be solved by the invention is to provide a device for processing the broaching holes of thin-walled ring gears, especially suitable for processing thin-walled ring gears with thin walls and high quality requirements. [0004] In orde...
