Description

Technical Field

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

[0002] A Chinese patent with publication number CN114054862A discloses a gear processing machine for cylindrical gear processing, including an operating table, and a rotating table is fixedly installed on the left side of the upper end of the operating table. The gear processing machine for cylindrical gear processing achieves the purpose of good gear gap processing effect by providing an operating table, a gear processor and a hydraulic cylinder. The hydraulic cylinder can control the lifting and lowering of the gear processor, so that the grinder and the processed gear can be controlled to be in the same plane, and the grinder and the processed gear belong to a meshing structure. However, when the device is in use, a movable grinder is used to grind the gear gap, and a grinding disc is used to grind part of the surface of the gear, but the upper and lower surfaces of the gear cannot be grinded, and the grinding effect is not good. At the same time, the generated debris will splash everywhere, causing inconvenience to subsequent cleaning. In addition, the position of the grinder facing the gear gap is fixed, and it needs to be adjusted when installing the gear, which is cumbersome to operate.

[0003] A Chinese patent with publication number CN115091355A discloses a tooth surface grinding device for processing reducer gears, including a box body, a mounting plate fixedly installed on the top of the box body. When the gear tooth surface needs to be ground, the gear is placed on the stud of the loading plate, and the gear is fixed with a locking nut, and then the hydraulic lifting rod is started to control the mounting plate to move downward, so that the grinding rod extends into the tooth gap of the gear. At the same time, the driving motor controls the grinding rod to rotate at high speed, so that the grinding rod can grind the bottom of the groove of the tooth gap, which is convenient for synchronous grinding of all the tooth gaps of the gear. However, the device can only grind the tooth gap of the gear using the rotating grinding rod, but cannot grind other parts near the tooth gap, and the grinding effect is not good. At the same time, the generated debris will splash everywhere, causing inconvenience to subsequent cleaning. In addition, the position of the grinding rod toward the gear gap is fixed, and it needs to be adjusted when installing the gear, which is cumbersome to operate.

[0004] In summary, the existing gear grinding devices have the following defects: First, they can only grind part of the gear, and the grinding effect is poor. Second, they cannot effectively prevent the generated debris from splashing, resulting in inconvenience in subsequent cleaning. Third, when installing the gear, the position of the gear needs to be adjusted, which is cumbersome. Summary of the invention

The rotation of the side grinding roller 631 will drive the brush 1 20 to rotate, and the rotation of the top grinding roller 632 will drive the brush 2 21 to rotate; when the transmission motor 13 is working, it will drive the transmission gear 1 65 to rotate, and under the action of the chain 67, it will drive the transmission gear 2 66 to rotate, and then drive the tooth gap grinding block 64 to move through the connecting arm 68; when the rotating motor 9 is working, it will drive the support table 41 to rotate, and then drive the reducer gear 5 to rotate; at the same time, using the existing encoding The device is used to control the operation of the rotating motor 9 and the transmission motor 13, so that when the rotating motor 9 drives the reducer gear 5 to rotate a tooth gap angle, the transmission motor 13 will drive a tooth gap grinding block 64 to grind the tooth gap of the reducer gear 5, so that the tooth gap, top surface, bottom surface and side surface of the reducer gear 5 can be polished, so as to achieve comprehensive grinding of the reducer gear 5. After grinding, the reducer gear 5 will rotate to the initial state (according to the grinding needs, the reducer gear 5 can be driven to rotate a few more circles to improve the grinding effect). At the same time, the moving cylinder 10 drives the folding plate 11 to reset, and the positioning block 75 moves to the tooth gap of the reducer gear 5 under the action of the positioning mechanism 7. After that, the clamping block 43 is removed, and then the reducer gear 5 is removed.
