Description

TECHNICAL FIELD

[0001] The application relates to the field of speed reducer machining technology, in particular to a spraying equipment for speed reducer machining. BACKGROUND

[0002] The speed reducer is an independent component composed of gear transmission, worm transmission and gear-worm transmission enclosed in a rigid shell, commonly used as a speed reduction transmission device between a prime mover and a working machine, and plays a role in matching the rotating speed and transmitting the torque between the prime mover and the working machine or the actuator, and is widely used in modern machinery.

[0003] The spraying equipment for speed reducer maintenance disclosed by the patent number CN213612170U can drive the supporting rod to ascend or descend by rotating the threaded rod, so that the distance between the supporting rod and the speed reducer can be adjusted according to the height of the speed reducer, the second conveying pipe and the speed reducer can be adjusted in distance according to the size of the speed reducer by pushing the sliding seat after loosening the fixing bolts, the number of on-off of the first spray head and the second spray head can be controlled by setting the first control valve and the second control valve, so that the spraying equipment can be suitable for speed reducers of different sizes, thereby meeting the use requirements of speed reducers of different sizes and improving the practicability of the spraying equipment. The rotation of the driving wheel and the driven wheel driven by the speed reducer motor can drive the rotating shaft to rotate the rotating disc, so that the speed reducer placed on the rotating disc can rotate, thereby the speed reducer can be sprayed comprehensively, and the practicability of the spraying equipment is further improved. However, in actual use, the speed reducer is uniformly sprayed by making it rotate in a circle. If the shape of the speed reducer is not approximately cylindrical during the rotation process, the distance between the spray head and the speed reducer will always change during the circumferential rotation process. If the distance between the spray head and the speed reducer is small, the spraying range is small and the spraying thickness is large. If the distance between the spray head and the speed reducer is too large, the spraying thickness is small, which cannot guarantee the quality of the spraying, and there are certain use defects.

[0004] Therefore, we propose a spraying equipment for speed reducer machining to solve the above-mentioned problems. SUMMARY

[0059] Embodiment one: as Figures 1-8 and Figure 10As shown, when spraying the reducer shell, the moving mounting plate 204 makes the support rod 202 slide on the vertical plate 201, the extension spring 203 is stretched, then the reducer shell is placed on the rotating plate 103, the mounting plate 204 is loosened, and the support rod 202 is reset and moved under the action of the extension spring 203, so that the roller 213 is in contact with the reducer shell, then the pump body inputs paint into the first input pipe 207 and the second input pipe 210, and the reducer is sprayed through the first spraying pipe 206 and the second spraying pipe 2091 on the movable pipe 205 and the mounting pipe 209. During the spraying process, the driving motor 102 is started to drive the rotating plate 103 to rotate clockwise, so that the reducer rotates, the rotating range of the reducer changes during rotation, so that the roller 213 can be moved and the roller 213 can rotate on the reducer, thereby moving the mounting plate 204, the mounting plate 204 moves to drive the connecting frame 229 to move, and then the rotating shaft 225 is driven to rotate through the cooperation of the rack 228 and the rotating gear 227.
