Description

Technical Field

[0001] The utility model relates to the technical field of gear processing, in particular to a grinding device for processing small gears of explosion-proof motors. Background Art

[0002] Gear processing is a process that uses mechanical methods to obtain a specific structure and precision of a gear. Gears are the core transmission components in automobile movement. The quality of their processing will have a direct impact on the vibration, noise and reliability of the automobile assembly and even the entire vehicle, and sometimes it will become a key factor restricting the improvement of product level. After the gear processing is completed, it needs to be polished to ensure the meshing accuracy of the gear.

[0003] For example, the Chinese patent publication number CN220127764U, "A grinding device for processing small gears of explosion-proof asynchronous motors", discloses the following technical solution: This utility model relates to the technical field of gear grinding devices, and discloses a grinding device for processing small gears of explosion-proof asynchronous motors, including a grinding table, a fixed frame fixedly installed at the bottom of the grinding table, a collection box inserted inside the fixed frame, a filter fixedly installed inside the grinding table, a gear fixing mechanism arranged outside the grinding table, and a grinding mechanism arranged on the top of the grinding table. This grinding device for processing small gears of explosion-proof asynchronous motors drives the threaded rod to rotate by the second motor, so that the threaded rod cooperates with the threaded cylinder to make the sliding cylinder move up and down inside the rotating cylinder to adjust the height, thereby adjusting the installation height of the gear, facilitating the adjustment of the installation height according to the model of the gear, without the need for a pad, and making the installation more convenient, and at the same time, the rotating cylinder is driven to rotate by the first motor, so that the rotating cylinder drives the gear to rotate and adjust the grinding position, thereby facilitating the grinding of different positions of the gear.

[0004] However, in actual use, when grinding the gear, it is necessary to first insert the gear into the outside of the threaded column, and then screw the threaded sleeve into the outside of the threaded column by turning the knob, and make the threaded sleeve and the sliding sleeve press and fix the gear. When the size of the hole on the gear does not match the threaded column, the gear is easy to loosen, resulting in a decrease in accuracy during grinding, which is not convenient for stable installation of the gear.
