Technical Field

[0001] The invention relates to the technical field of gear shaft processing, in particular to a gear shaft grinding processing device for a planetary reducer. Background Art

[0002] The gear shaft of the gear reducer is a very important component, which is mainly used to transmit power and torque; the gear shaft is a key component in the reducer, and its quality and performance directly affect the working condition and service life of the entire reducer; the gear shaft is usually composed of a journal, gears, bearings and other parts. The journal is the main load-bearing part of the gear shaft and usually needs to withstand a large torque, so it needs to have high strength and rigidity; the gear is the core part of the gear shaft, which meshes with the gears of the motor or other power source being reduced, and transmits power to the output shaft through the meshing of the gears; the bearing is the supporting part of the gear shaft, which is used to support the gears and journals to reduce friction and wear.

[0003] At present, after completing the processing and production of the gear shaft for the reducer, since the surface roughness of the shafts on both sides of the gear shaft does not meet the requirements, the gear shaft will be further ground to obtain a gear shaft with surface accuracy that meets the requirements. In the prior art, a grinding device is directly used to grind the shaft. During the grinding process, the grinding device may cause some waste chips to fall on the gear shaft due to the splashing of waste chips, thereby causing the waste chips to scratch the gear shaft.

[0014] By adopting the above technical solution, the vertical position of the grinding wheel can be adjusted.

[0015] In summary, the present invention mainly has the following beneficial effects: 1. The present invention sets a grinding assembly and a waste chip cleaning assembly. First, the gear shaft to be ground is installed between two sets of chucks and clamped and limited. Then, the double-headed motor can be started. After the double-headed motor is started, it will drive the rotating shaft to rotate. After the rotating shaft rotates, it will drive the grinding wheel to rotate, so that the grinding wheel can achieve the grinding effect on the gear shaft. At the same time, the rotation of the rotating shaft will also drive the blades to rotate. After the blades rotate, wind will be generated, so that the waste chips generated by the grinding wheel will be sucked into the dust collection box, and the gas containing the waste chips will flow into the air pipe and be injected into the air diffuser through the air inlet pipe. Then, a large amount of gas will gush out through the air outlet opened at the bottom of the air diffuser, so as to achieve air cooling of the grinding wheel, thereby improving the grinding quality of the grinding wheel on the gear shaft; 2. The present invention sets a driving component and an adjusting component. When the above-mentioned rotating shaft rotates, the rotating shaft will also drive the first driven gear connected to its end to rotate. After the first driven gear rotates, it will drive the driving gear to rotate through the first rack. After the driving gear rotates, it will drive the second driven gears on both sides to rotate through the second rack. After the second driven gear rotates, it will drive the bidirectional screw to rotate, so that the moving block on the bidirectional screw can perform horizontal reciprocating movement within a certain range, and the movement of the moving block will drive the end plate to move, thereby realizing the horizontal reciprocating movement of the gear shaft, which is conducive to the grinding wheel to perform all-round and dead-angle grinding of the gear shaft, and further improve the grinding production quality of the gear shaft. In addition, the rotation of the driving gear will also drive the telescopic shaft at its end to rotate, and the rotation of the telescopic shaft will drive the first bevel gear to rotate. The first bevel gear then drives the third bevel gear to rotate in the opposite direction under the action of the second bevel gear, and the reverse rotation of the third bevel gear will drive the chuck to rotate, which makes the gear shaft rotate in the opposite direction to the rotation direction of the grinding wheel, and the grinding wheel and gear shaft in the opposite direction can be better ground. Furthermore, in the reciprocating movement of the moving block, it will also drive the adjusting component to operate to adjust the vertical position of the grinding wheel. Specifically, when the moving block completes the unidirectional movement and moves in the reverse direction, the driving tooth plate on the outer wall of the moving block will drive the driven gear seat to rotate, and then the driven gear seat will drive the screw rod to rotate a certain angle, which makes the slider on the outer wall of the screw rod move downward a short distance, thereby compensating the motion of the grinding wheel section to prevent the problem that the grinding wheel cannot be effectively ground due to the reduction of the outer diameter caused by the grinding of the gear shaft.
