Description

Technical Field

[0001] The utility model relates to the technical field of flange surface treatment, and more specifically, the utility model relates to a flange polishing device for a speed reducer. Background Art

[0002] The high-pressure resistant flange is a connecting component specifically designed for a speed reducer, which can withstand high pressure and large torque, ensuring the stability and reliability of the speed reducer during operation. It is usually made of high-strength materials and has good wear resistance and corrosion resistance. However, in the actual use process of this kind of flange, there are still some disadvantages. For example, due to the large influence of the frictional force between the structural surfaces during the rotation of the speed reducer, therefore, the surface of the high-pressure resistant flange made of high-strength materials needs to be polished to reduce the friction coefficient of the flange surface and reduce the impact on the operation of the speed reducer. However, during the polishing process, it is usually necessary to change grinding wheels with different mesh numbers for polishing. And the connection method between some grinding wheels and the driving motor is generally fixed by bolts. This results in that during each replacement, tools such as wrenches are needed for disassembly, which not only reduces the actual polishing efficiency, but also frequent disassembly will cause wear to the connecting thread grooves, resulting in a reduction in the connection safety.

[0033] Afterwards, the pulley 1 230 is rotated by the rocker 233, so that the pulley 2 232 connected by the track 231 rotates, driving the fixed screw 22 to rotate in contact with the inner walls of the two vertical plates 20, and the polishing mechanisms 24 threadedly connected to the screw 22 move laterally along the limit column 21, so that the polishing wheel 245 of the appropriate mesh number reaches the position located at the center axis of the flange, and then, the electric push rod 1 242 is controlled to extend, and the cover box 243 connected at the end is pushed to move in the direction close to the flange until the surface of the polishing wheel 245 is against the flange.
