Description

Technical Field

[0001] This utility model relates to the field of speed reducer manufacturing technology, and in particular to a gear groove polishing device for speed reducer gear processing. Background Technology

[0002] A speed reducer is a relatively precise piece of machinery used to reduce speed and increase torque. It plays a role in matching speed and transmitting torque between the prime mover and the driven machine or actuator. Its working principle is that a small gear drives a large gear to achieve a certain speed reduction. By using a multi-stage structure, the speed can be significantly reduced and the torque increased. Gears are an essential component of a speed reducer; their quality determines the stability of the transmission, the accuracy of the reduction ratio, and the level of vibration and noise. During the production process, speed reducer gears require surface treatment using deburring equipment.

[0003] To address this, the patent specification with publication number CN217750766U discloses a convenient deburring device for reducer gears, including a mounting plate. A material-supporting mechanism is installed at the center of the mounting plate, and a material-pushing mechanism, a grinding mechanism, and a material-unloading mechanism are mounted around the material-supporting mechanism. The material-supporting mechanism, material-pushing mechanism, grinding mechanism, and unloading mechanism work together. The material-supporting mechanism is used to place reducer gears in batches, the grinding mechanism is used to grind and deburr the tooth edges of the reducer gears in batches, and the material-pushing mechanism is used to synchronously switch the tooth edge areas to be ground in batches. Before switching, the grinding mechanism retracts, and after switching, it resets. After all grinding is completed, the unloading mechanism quickly unloads the gears. The overall operation is convenient and reduces the labor intensity of workers.

[0004] However, this type of gear deburring device still has shortcomings in use. It cannot switch between different polishing blocks according to polishing requirements, and cannot achieve continuous, graded polishing. Therefore, its structure needs to be optimized and improved.

[0013] Furthermore, in the aforementioned gear grinding and polishing device for gear processing of reducers, the servo motor can drive the support shaft and the multi-angle grinding block to rotate at a certain angle, which matches the central angle between two adjacent convex angles in the multi-angle grinding block.

[0014] Furthermore, in the aforementioned gear grinding device for gear processing, the multi-angle grinding block is provided with four convex angles that mate with the tooth grooves in the gear workpiece, and the central angle between two adjacent convex angles is 90 degrees.

[0015] Furthermore, in the aforementioned gear grinding and polishing device for gear processing of reducers, the telescopic connecting member is composed of a sliding sleeve, a sliding rod, and a helical spring.
