Technical Field

[0001] The utility model relates to the technical field of gear shaft grinding processing, in particular to a gear shaft grinding processing device. Background Art

[0002] A gear shaft grinding processing device is a mechanical device used to improve the accuracy and surface quality of gear shafts. These devices usually include key components such as a frame, a clamping unit, a grinding unit, etc., and can perform precision grinding on internal and external gears.

[0003] A gear shaft grinding processing device disclosed in the patent document with the publication number CN117961674A for the production of a speed reducer includes two symmetric support platforms. A console is fixedly arranged on the upper ends of the two support platforms. A motor is fixedly arranged at the rear side of the lower end of the console. A feeding component is fixedly arranged at the rear side of the upper end of the console. A support plate is fixedly arranged at the rear side of the upper end of the console. A transmission shaft is arranged at the right end of the support plate. The transmission shaft is connected to the output end of the motor through a belt. A stepping mechanism is arranged at the upper end of the console and is matched with the feeding component. An L-shaped block is fixedly arranged at the front end of the console. A grinding processing component matched with the stepping mechanism is fixedly arranged at the upper end of the vertical part of the L-shaped block. Thus, the two rotating shafts rotate. While the linkage shaft rotates, the cross block rotates to turn the gear shaft off the two placing blocks and roll along the placing blocks into the inner cavity of the first slot near the right-angled triangular block among the two first slots. Then, as the two rotating shafts rotate, the two stepping plates rotate, so as to convey the gear shaft in the inner cavity of the two last first slots to the front side, thereby forming intermittent feeding for the grinding processing component. It can not only facilitate the feeding of the device but also improve the processing efficiency of the device.
