Description

Technical Field

[0001] The utility model relates to the technical field of gear shaft processing fixtures, and particularly relates to a gear shaft clamping and rotating processing seat. Background Art

[0002] During the processing of gear shafts, it is necessary to clamp and fix the gear shafts for easy processing. The existing clamping method is to keep the gear shaft in a vertical state. One end of the gear shaft is clamped by a fixture on a hobbing machine at its end, and the other end of the gear shaft is abutted by a center set on the hobbing machine to prevent the gear shaft from swinging during processing. However, the disadvantage of this method is that due to the limitation of the stroke of the center in the vertical direction, only gear shafts of a certain length can be processed. If the gear shaft is too long or too short, it is not convenient for the center to abut against the end of the gear shaft, which has certain drawbacks.

[0003] The prior art CN215393855U discloses a clamping device for gear shaft processing, including: a support seat assembly, which includes a base and a rotating seat. The base includes a support part and a mounting part. The support part is used for fixedly connecting with the frame of the hobbing machine. One end of the rotating seat is hinged to one end of the mounting part, and the other end of the rotating seat is detachably connected to the other end of the mounting part through a locking member. A channel for clamping the shaft part of the gear shaft is formed between the rotating seat and the mounting part; and a clamping assembly, with at least three clamping assemblies evenly distributed on the top of the closed ring formed by the rotating seat and the mounting part. The clamping assembly is used to clamp the shaft part of the gear shaft in the channel, solving the problem that it is not convenient to clamp the gear shaft during gear shaft processing in the prior art.

[0004] However, when the above-mentioned clamping device for gear shaft processing is actually used in processing, the base and the rotating seat are connected and fixed by fastening bolts. During the mass production of products, for each product during processing, it is necessary to manually install the fastening bolts and use them after connecting and matching the base and the rotating seat, which seriously affects the production and processing efficiency of mass products.
