Rapid alignment equipment for tooth aligning and gear hobbing of small gear shaft

Abstract

The invention discloses rapid alignment equipment for tooth aligning and gear hobbing of a small gear shaft. The rapid alignment equipment comprises a first corner plate, a second corner plate arranged on the side wall of the first corner plate, a sliding plate arranged at the top of the first corner plate and a base arranged on the sliding plate, a movable alignment column is arranged on the base, a detachable modulus measuring head is arranged on the alignment column, a U-shaped block is arranged at the front end of the sliding plate, a U-shaped groove is formed in the U-shaped block, the base is arranged on the U-shaped block and can be horizontally rotated, and a moving assisting mechanism for assisting the base in rotating horizontally is arranged at the bottom of the base. A hob doesnot need to be firstly clamped into a tooth groove for tooth aligning, the base only needs to be moved and adjusted in all directions, tooth aligning can be realized only by clamping the modulus measuring head into the tooth groove, the trouble and difficulty of tooth aligning are reduced, the gear hobbing efficiency of the gear shaft is effectively improved, and thus the production efficiency isimproved.

Description

technical field [0001] The invention belongs to the technical field of hobbing processing equipment for gear shafts, and in particular relates to a rapid alignment equipment for gear hobbing of pinion shafts. Background technique [0002] The pinion shaft is a commonly used part in the reduction box. The pinion shaft generally has fewer teeth, small outer diameter, and short length. Now, this kind of short gear shaft is generally processed by hobbing after heating, and the gear is hobbed by upper forming grinding. However, when hobbing Due to the small diameter of the tooth part, the grinding wheel and the workpiece headstock are very easy to interfere, so that only small grinding wheels can be used for grinding, and the grinding wheels need to be changed frequently, so the production efficiency is low; subsequent heat hobbing is used for hard hobbing on an ordinary gear hobbing machine, but it needs to be processed every time After a pinion shaft clamps the hob into the gea...

[0002] The pinion shaft is a commonly used part in the reduction box. The pinion shaft generally has fewer teeth, small outer diameter, and short length. Now, this kind of short gear shaft is generally processed by hobbing after heating, and the gear is hobbed by upper forming grinding. However, when hobbing Due to the small diameter of the tooth part, the grinding wheel and the workpiece headstock are very easy to interfere, so that only small grinding wheels can be used for grinding, and the grinding wheels need to be changed frequently, so the production efficiency is low; subsequent heat hobbing is used for hard hobbing on an ordinary gear hobbing machine, but it needs to be processed every time A pinion shaft clamps the hob into the tooth portion of the pinion shaft to achieve tooth alignment, which leads to low production efficiency.
