Description

Technical Field

[0001] The utility model relates to the technical field of speed reducer processing, in particular to a spraying device for speed reducer processing. Background Art

[0002] A reducer, also known as a speed reducer, gearbox or gearbox, is an independent component composed of a gear transmission, a worm transmission, a gear and a worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting torque between the prime mover and the working machine or the actuator. During the operation of the reducer, its surface may be subject to friction and wear. By spraying paint, a wear-resistant layer can be formed on the surface of the reducer to reduce the occurrence of wear and extend the service life of the reducer.

[0003] Patent No. CN214975103U in the prior art discloses a spraying device for processing a reducer. The manual spraying of the reducer shell has a slow and uneven spraying speed, resulting in a poor spraying effect, and the hands will be stained with anti-rust paint, which is not convenient to clean. Therefore, it is easy to use, simple to operate, easy to fix, and the spraying is uniform, and the spraying effect is good. However, the prior art still has shortcomings in actual use. When spraying the reducer, the reducer can usually only be fixed, so that the position of the reducer is fixed during the spraying. It is not convenient to rotate after clamping according to the spraying needs, which can easily reduce the uniformity of the reducer spraying, thereby reducing the spraying quality. Therefore, manual intervention is required to release the clamping and turn the direction of the reducer, and then fix it and spray it, which is more troublesome and complicated to operate, which reduces the spraying efficiency and easily prolongs the working time.

Blocks 15 are fixedly connected to both ends of the push spring 14. The rack 4 is pushed to move by the output end of the hydraulic cylinder 3, so that the rack 4 drives the gear 5 to rotate, which makes it convenient for the gear 5 to drive the rotating disk 6 to rotate, thereby driving the reducer to rotate. By sliding the clamping rod 11 inside the fixed tube 10, the clamping height of the clamping rod 11 can be adjusted according to the force point of the reducer to be clamped.

[0029] Embodiment 2:

[0030] A motor 218 is fixedly installed at the rear end of the top of the fixed plate 2, a threaded rod 19 is rotatably connected to the left end of the top of the fixed plate 2, the other end of the threaded rod 19 is fixedly connected to the output end of the motor 218, the external thread of the threaded rod 19 is connected to a paint box 20, the bottom end of the paint box 20 is fixedly connected to a folding tube 21, the other end of the folding tube 21 is fixedly connected to a paint spray head 22, and a slide groove 23 is provided at both the left and right ends of the top of the fixed plate 2, the inside of the slide groove 23 is slidably connected to a slide rod 24, the other ends of the two slide rods 24 are fixedly connected to an arc block 25, the outside of the arc block 25 is slidably connected to a moving sleeve 26, and the rear end of the moving sleeve 26 is fixedly connected A telescopic rod 27 is connected, and an arc groove 16 is set in the middle of the rear end of the fixed plate 2.

The cross-section of the arc groove 16 is set to a "cross" shape, and one end of the telescopic rod 27 is also set to a "cross" shape, so that the telescopic rod 27 slides inside the arc groove 16.

[0031] Working principle: When clamping and fixing the reducer, first place the reducer on the top of the rotating disk 6. According to the size and force position of the reducer, when adjusting the height of the clamping rod 11, press the blocks 15 on both sides so that the blocks 15 on both sides are squeezed to the middle to push the spring 14, so that the blocks 15 on both sides are retracted into the inside of the installation groove 13, so as to facilitate the release of the clamping with the corresponding hole groove 12, and then the clamping rod 11 is released from the limit state, and then the clamping rod 11 is pulled to facilitate the sliding of the clamping rod 11 inside the fixed tube 10, so as to facilitate the adjustment of the position of the clamping force of the reducer at the top of the clamping rod 11. After that, under the pushing action of the pushing spring 14, it is convenient for the pushing spring and 14 to push the two-side blocks 15 into the corresponding hole grooves 12, so that the clamping rod 11 after being pulled is limited and fixed, and then the motor 17 is turned on, so that the output end of the motor 17 drives the bidirectional screw 8 to rotate, so that the bidirectional screw 8 drives the moving plates 9 on both sides to approach each other, so that the moving plates 9 slide on the outside of the stabilizing rod 17 at the same time, and then the moving plate 9 indirectly drives the clamping rod 11 to clamp and fix the reducer, thereby improving the stability of the reducer. When the reducer needs to be rotated during the spraying process, the hydraulic cylinder 3 is turned on. The output end of the hydraulic cylinder 3 is extended and retracted to drive the rack 4 to move. The meshing of the rack 4 and the gear 5 is conducive to driving the gear 5 to rotate, which is convenient for the gear 5 to drive the rotating disk 6 to rotate, thereby facilitating the rotation of the clamped reducer, thereby improving the uniformity of the reducer spraying. When it is necessary to adjust the position of the paint spray head 22 according to the spraying needs of the reducer, the motor 18 is turned on, and the motor 18 drives the threaded rod 19 to rotate, so that the threaded rod 19 drives the paint box 20 to move forward and backward. In the process of the movement of the paint box 20, the folding tube 21 and the paint spray head 22 are driven to move forward and backward, so that the paint spray head 22 is moved forward and backward at the same time. When the arc block 25 is driven, the two sliding rods 24 are driven to slide inside the slide groove 23, so that the telescopic rod 27 is extended and retracted. When the paint spraying angle of the paint spray head 22 needs to be adjusted, the bolt 28 on the rear side is held, so that the bolt 28 drives the telescopic rod 27 to move inside the arc groove 16, and drives the moving sleeve 26 to move outside the arc block 25, thereby driving the paint spray head 22 to adjust the angle, so that the folding tube 21 is deformed. After adjustment, the nut 29 outside the bolt 28 is tightened to fix the bolt 28, so as to fix the angle position of the paint spray head 22 after the angle adjustment, so as to meet the processing requirements.

[0032] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
