Description

Technical Field

[0001] The invention belongs to the technical field of automobile air-conditioning compressor spraying, and in particular relates to an automobile air-conditioning compressor anti-rotation ring spraying device. Background Art

[0002] The anti-rotation ring of the automobile air-conditioning compressor, also known as the anti-reverse device, is a component designed to prevent the compressor from reversing after the engine stops working. When the automobile engine is turned off, if the compressor continues to rotate due to inertia, especially when there is still a certain pressure in the air-conditioning system, it may cause damage to the piston, valve and other components inside the compressor. The anti-rotation ring can prevent this abnormal operation and protect the compressor from damage. Preventing the compressor from reversing can reduce unnecessary wear of bearings and other moving parts and extend the service life of the compressor. The anti-rotation ring is usually implemented through mechanical structure design, such as the principle of a one-way clutch or a check valve. When the compressor is working normally, it allows the compressor to rotate synchronously with the engine crankshaft; when the engine stops, it automatically locks to prevent the compressor from reversing. Spraying a layer of anti-corrosion paint on the anti-rotation ring can increase the corrosion resistance of the anti-rotation ring, especially in environments with high humidity or salt spray corrosion risks, which can extend the service life of the components. There are also some high-performance paints that can improve the surface smoothness of the base material, reduce friction, and benefit the overall operating efficiency of the compressor. In order to achieve mass production, a spraying device will be used to spray multiple groups of anti-rotation rings together. However, in the prior art, spraying the anti-rotation ring will result in uneven spraying.

[0003] The existing Chinese patent document with announcement number CN210333175U proposes to solve the above problem by using a base plate, a U-shaped bracket is arranged on the top of the base plate, a cover shell with an opening is installed at the bottom of the bracket, a turntable is movably sleeved on the top inner wall of the cover shell, the bottom of the turntable is fixedly connected with a U-shaped nozzle, the bottom ends of the nozzle are fixedly connected with connecting pipes, the ends of the two groups of connecting pipes close to each other are connected to the nozzle, and the sides of the two groups of connecting pipes away from each other are fixedly sleeved with a movable ring of the same annular structure, and the movable ring is movably sleeved with a storage box of annular structure. However, the anti-rotation ring of the air-conditioning compressor is an annular structure, and there is a blind area for the inner surface spraying by the paint spraying device in the prior art, which makes the inner surface spraying incomplete.

[0004] Therefore, the present invention proposes a spraying device for an anti-rotation ring of an automobile air-conditioning compressor, which solves the problem in the prior art that the spraying device has a blind area when spraying the inner surface of the anti-rotation ring of the automobile compressor, resulting in incomplete spraying of the inner surface. The spraying pipeline is designed so that it can spray the inner and outer surfaces of the anti-rotation ring when the anti-rotation ring of the automobile compressor passes through.

The inner wall of the U-shaped spray pipe 25 is symmetrically provided with a straight nozzle 251 and an oblique nozzle 252, and the oblique nozzle 252 is inclined at 45 degrees. A reversing motor 253 is fixedly installed in the middle of the outer surface of one side of the U-shaped spray pipe 25, and an annular ball valve 2531 is rotatably installed in the middle of the inner surface of the U-shaped spray pipe 25.

The side surface of the sealing conduit 2532 is fixedly connected to the inner surface of the U-shaped spray pipe 25, and sealing plugs 2533 are symmetrically arranged on the upper and lower sides of the annular ball valve 2531, and a trapezoidal through hole matching the right-angle flow groove of the annular ball valve 2531 is arranged in the middle of the sealing plug 2533;

[0034] In this embodiment, the fixing plate 31 uses a cross fixing frame 32 to fix the anti-rotation ring, and the fixing plate 31 is fixed on the lifting and moving equipment 11 by the installation clamp 311 and the lifting clamp 12. When the fixing plate 31 moves to the position of the spray rack 21, the telescopic rod 23 pushes the slide plate 22 to slide to the limit position on the sliding limit beam 211, so that the wind cover 24 is stuck in the anti-rotation ring. First, the inner surface of the anti-rotation ring is sprayed, and the reversing motor 253 rotates the annular ball valve 2531 so that the right-angle flow groove of the annular ball valve 2531 is downward.

The air outlet slot 241 guides the airflow so that it is discharged through the air outlet slot 241, and the air guide plate 242 further guides the airflow so that it is blown obliquely inward, so that the paint sprayed by the U-shaped spray tube 25 is blown and fixed on the surface of the anti-rotation ring, thereby accelerating its drying.

[0041] Embodiment 4

[0042] See also Figures 1 to 12On the basis of the third embodiment, in order to facilitate the fixing of the anti-rotation ring, the present embodiment further proposes that a cross fixing frame 32 is rotatably installed on one side of the fixing plate 31 close to the slide plate 22, and a motor 33 is fixedly installed on the other side of the fixing plate 31, and the output shaft of the motor 33 is fixedly connected to one end of the rotating shaft of the cross fixing frame 32, and mounting clamps 311 are symmetrically arranged on the upper and lower sides of the motor 33, and one end of the mounting clamp 311 is clamped with one end of the lifting clamp 12, and an outer ring clamping frame 322 is symmetrically arranged on the outer side of the cross fixing frame 32, and an inner ring clamping frame 321 is arranged on one side of the outer ring clamping frame 322, and the outer ring clamping frame 322 has the same structure as the inner ring clamping frame 321, and the outer ring clamping frame 322 and the inner ring clamping frame 321 are both rotatably installed on the inner wall of the cross fixing frame 32, and gears are fixedly installed on both sides of the rotating shafts of the outer ring clamping frame 322 and the inner ring clamping frame 321. A Z-shaped sliding rod 323 is arranged between the holder 321 and the outer ring clamping frame 322, and a rack matched with the gears on both sides of the inner ring clamping frame 321 and the outer ring clamping frame 322 is arranged on the side surface of the Z-shaped sliding rod 323, and the outer surface of the Z-shaped sliding rod 323 is slidably connected with the inner surface of the cross fixing frame 32, and a threaded rod 324 is symmetrically rotated and installed on the inner surface of the cross fixing frame 32, and the inner wall of one side of the Z-shaped sliding rod 323 is threadedly connected with the outer surface of the threaded rod 324, and a small bevel gear 3241 is fixedly installed on the end of the threaded rod 324 away from the outer ring clamping frame 322, and a large bevel gear 325 is arranged above the small bevel gear 3241, and the outer surface of the large bevel gear 325 is meshed with the outer surface of the small bevel gear 3241, and an adjustment motor 326 for driving the large bevel gear 325 to rotate is fixedly installed in the middle of the side surface of the cross fixing frame 32;

[0043] In this embodiment, the anti-rotation ring is placed on the outer side of the inner ring clamping frame 321, so that the anti-rotation ring can be supported and clamped by the inner ring clamping frame 321, and the fixed plate 31 moves, and the hoisting moving device 11 moves intermittently so that the anti-rotation ring is moved to one side of the spraying frame 21 for outer surface spraying. After spraying, the adjustment motor 326 drives the large bevel gear 325 to rotate.

[0047] Embodiment 6

[0048] See also Figures 1 to 12 Based on the fifth embodiment, this embodiment further proposes a spraying method for a spraying device for an anti-rotation ring of an automobile air-conditioning compressor, comprising the following steps:

The reversing motor 253 rotates the annular ball valve 2531 to control the branch pipe below the U-shaped spray pipe 25 to pass through. The straight nozzle 251 and the oblique nozzle 252 spray the outer ring of the anti-rotation ring. At this time, the motor 33 drives the cross fixing frame 32 to rotate so that the entire outer ring of the anti-rotation ring is sprayed. At the same time, the fan 26 works to air dry the spraying area through the wind hood 24. The air outlet slot 241 and the air guide plate 24 2 makes the paint sprayed by the U-shaped spray pipe 25 be blown and fixed on the surface of the anti-rotation ring, and then when the inner ring clamping frame 321 is staggered with the wind cover 24, the motor 33 stops rotating, and at this time, the motor 326 is adjusted to control the rotation of the threaded rod 324 to drive the Z-shaped sliding rod 323 to slide, so that the outer ring clamping frame 322 is turned over 90° to fix the outer side of the anti-rotation ring, and the inner ring clamping frame 321 is turned over 90° to lie flat, and then the reversing motor 253 is used to rotate the annular ball valve 2531 to control the branch pipe above the U-shaped spray pipe 25 to pass through, and the straight nozzle 251 and the oblique nozzle 252 spray the inner ring of the anti-rotation ring;

[0051] Step three, withdrawing the material.
