Description

Technical Field

[0001] The present invention relates to the field of motor housing processing, specifically a painting device for motor processing. Background Art

[0002] A motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction. It is divided into a motor and a generator. The motor housing is one of the important components of the motor. It is usually used to protect the internal components of the motor from the external environment and at the same time play a role in fixing and supporting the motor structure. Most of the motor housings are made of metal materials. In order to avoid corrosion of the housing, during the production of the motor, it is necessary to spray a protective coating paint on the outer side of the housing. When the existing motor housing painting device is in use, the motor housing is limited and fixed on the top of a rotatable turntable or tray. During the spraying process, the turntable or tray can be driven by a driving motor to rotate uniformly, so that the outer surface of the motor housing can be evenly sprayed through the spraying structure. However, during the spraying process, a large amount of paint will adhere to the top of the turntable or tray, resulting in the need to clean the turntable or tray after the spraying work is completed, and some paint will be wasted. For this reason, we propose a painting device for motor processing. Summary of the Invention

[0014] Preferably, a control switch is fixedly installed on the outer wall of the paint tank.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. When the present invention is in use, the motor housing is clamped and fixed by the clamping assembly. During the painting process, it is inevitable that paint will drip on the outer wall of the motor housing. Since there is no turntable or tray at the bottom of the motor housing, the paint will directly pass through the through hole and flow back into the paint tank, which can reduce the waste of paint.

[0017] 2. When the present invention is in use, the stirring blades and the scraping plates can be driven to rotate by the driving of the servo motor. The rotation of the stirring blades will continuously stir the paint in the paint tank to prevent the paint from precipitating. Since the scraping plates are slidably attached to the inner wall of the paint tank, the rotation of the scraping plates will continuously clean the inner wall of the paint tank; it can also drive the motor housing clamped by the clamping assembly to rotate; it can also drive the spray head to continuously move up and down; by continuously moving the spray head up and down and cooperating with the rotation of the motor housing, the motor housing can be evenly painted.

[0018] 3. When the present invention is in use, according to the different heights of the motor housing to be painted, rotate the threaded fixing member so that the threaded fixing member disengages from the threaded hole opened in the L-shaped block. At this time, the screw rod can be slid up and down, and then the distance between the pressing block and the moving plate (at this time, the top end of the moving plate fits against the L-shaped frame, as shown in the attachment Figure 1 shown) can be adjusted, and then the range of the downward movement of the pressing block can be adjusted. Then, rotate the threaded fixing member again so that the threaded fixing member is threadedly connected to the threaded hole opened in the L-shaped block and the screw rod at the same time, so as to make the connection stable, and then the range of the up and down movement of the spray head can be controlled to ensure that during the painting process, the paint sprayed by the up and down moving spray head is evenly sprayed on each position of the motor housing, and then the uniform painting of the motor housing is completed.

[0019] 4. When the rotating column rotates, the lifting rod will rotate following the rotating column under the action of the four base blocks. Since the upper end of the lifting rod is rotatably connected to the lifting block through a bearing, the lifting block will not block the rotation of the lifting rod.

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figure 1 - Figure 6 , the figure shows a motor processing paint spraying device of the present invention, including a paint spraying box 1, the paint spraying box 1 is rotatably connected to the rotating column 201 in the clamping component 2 through a bearing, the bottom of the paint spraying box 1 is fixedly connected to a paint tank 3, a through hole 4 is opened at the top end of the paint tank 3, a paint spraying auxiliary component 5 is fixedly installed at the top end of the paint spraying box 1, a group of sprockets 6 are fixedly sleeved on the outer walls of the reciprocating lead screw 501 and the rotating column 201 in the paint spraying auxiliary component 5, and the two groups of sprockets 6 are fixedly engaged with a chain 7;

[0029] The clamping assembly 2 includes a rotating column 201. A top plate 202 is fixedly connected to the bottom of the rotating column 201. A set of limit sliders 204 are respectively slidably connected in four groups of limit sliding grooves 203 opened in the top plate 202. A set of clamping plates 205 are respectively fixedly connected to the bottoms of the four groups of limit sliders 204. Elastic rubber plates 206 are fixedly connected to the outer sides of the clamping plates 205. Lugs at the tops of the four groups of limit sliders 204 respectively rotate a set of connecting plates 207. The four groups of connecting plates 207 are respectively rotatably connected to a set of base blocks 208. The four groups of base blocks 208 respectively slide inside four groups of lifting grooves 209 opened in the rotating column 201. The four groups of base blocks 208 are all fixedly connected to the outer wall of a lifting rod 210. The lower end of the lifting rod 210 is slidably connected in the inner cavity of the rotating column 201. The upper end of the lifting rod 210 is rotatably connected to a lifting block 211 through a bearing. The lifting block 211 is fixedly installed on the telescopic end of an electric push rod 212. The electric push rod 212 is fixedly installed on the top of the paint spraying box 1. During use, the motor housing to be painted is attached to the bottom of the top plate 202. Then, the electric push rod 212 is started to drive the lifting plate 211 to move downward. The downward movement of the lifting plate 211 drives the lifting rod 212 to move downward. The downward movement of the lifting rod 212 will drive the four groups of base blocks 208 to move downward along the lifting grooves 209. Under the action of the connecting plates 207, it drives the four groups of limit sliders 204 to slide along the limit sliding grooves 203, thereby driving the four groups of clamping plates 205 to gradually approach the inner wall of the motor housing until the elastic rubber plates 206 are closely attached to the inner wall of the motor housing, and then stably fixing the motor housing to the bottom of the top plate 202. When the rotating column 201 rotates, under the action of the four groups of base blocks 208, the lifting rod 210 will rotate following the rotating column 201. Since the upper end of the lifting rod 210 is rotatably connected to the lifting block 211 through a bearing, the lifting block 211 will not block the rotation of the lifting rod 210.

[0030] The paint spraying auxiliary assembly 5 includes a reciprocating lead screw 501. The reciprocating lead screw 501 is rotatably connected to an auxiliary frame 502 through two groups of bearings. The auxiliary frame 502 is fixedly installed on the top of the paint spraying box 1. The reciprocating lead screw 501 is threadedly connected to an L-shaped block 503. A screw rod 504 is slidably connected up and down inside the L-shaped block 503. A pressing block 505 is fixedly connected to the bottom of the screw rod 504. A threaded fixing member 506 can be threadedly connected to a threaded hole opened in the L-shaped block 503. The screw rod 504 can be threadedly connected to the inside of the threaded fixing member 506. A first guide rod 507 slidably penetrates through the inside of the L-shaped block 503. The top end and the bottom end of the first guide rod 507 are both fixedly connected to the auxiliary frame 502.

[0031] A paint pump 8 is fixedly installed on the outer wall of the paint tank 3. One end of a pipeline 9 is connected between the input end of the paint pump 8 and the bottom of the paint tank 3. One end of a pipeline 10 is connected to the output end of the paint pump 8. One end of a spring pipeline 11 is connected to the other end of the pipeline 10. One end of a pipeline 12 is connected to the other end of the spring pipeline 11. Several spray heads 13 are connected to the pipeline 12. The spray heads 13 are all located inside the spraying box 1. During use, starting the paint pump 8 can extract the paint inside the paint tank 3, and draw the paint into the spray heads 13 through the pipeline 9, pipeline 10, spring pipeline 13 and pipeline 12, and finally spray it out from the spray heads 13 and onto the outer wall of the motor housing to be processed. It should be noted that the paint pump 8 is a prior art. A paint pump is a device used to transport paint to a spraying device or a painting surface. The spray heads 13 are selected with a suitable spraying range to avoid the spraying range of the spray heads 13 being too large and difficult to control.

[0032] A fixing sleeve 14 is fixedly connected to the outer wall of the pipeline 10. The fixing sleeve 14 is fixedly installed on the outer wall of the L-shaped frame 15. The L-shaped frame 15 is fixedly installed on the outer wall of the spraying box 1, making the connection structure of the device stable.

[0033] The pipeline 12 slidably penetrates through the inside of the L-shaped frame 15, the top end of the spraying box 1 and the inside of the stabilizing block 16. The stabilizing block 16 is fixedly connected to the inner wall of the spraying box 1. A moving plate 17 is fixedly connected to the outer wall of the pipeline 12. A spring 18 is provided between the bottom end of the moving plate 17 and the top end of the spraying box 1. The spring 18 is in a compressed state. A second guiding rod 19 is fixedly installed between the L-shaped frame 15 and the spraying box 1. The second guiding rod 19 slidably penetrates through the inside of the moving plate 17. Since the spring 18 is always in a compressed state, when the top end of the moving plate 17 is not restricted, the top end of the moving plate 17 fits against the L-shaped frame 15. At this time, the highest point of the paint sprayed by the spray heads 13 is flush with the bottom of the top plate 202. The pipeline 12 can move up and down, thereby adjusting the spraying range of the spray heads 13. The second guiding rod 19 is provided to enable the moving plate 17 to stably drive the pipeline 12 to move up and down.

[0034] A door 20 that can be opened and sealed is hingedly installed on the spraying box 1. During use, opening the door 20 allows the motor housing to be painted to be installed on the clamping assembly 2 or the painted motor housing to be removed from the clamping assembly 2.

[0035] A fixed seat 21 is fixedly installed on the outer wall of the paint tank 3. The fixed seat 21 is rotationally connected to a transmission rod 22 through a bearing. A set of second sprockets 23 are respectively fixedly sleeved on the outer wall of the transmission rod 22 and the outer wall of the rotating column 201. The two sets of second sprockets 23 are both engaged with a second chain 24. During use, the transmission rod 22 rotates and drives the rotating column 201 to rotate under the transmission of the two sets of second sprockets 23 and the second chain 24. The rotation of the rotating column 201 drives the top plate 202 to rotate, and the rotation of the top plate 202 drives the clamped motor housing to rotate.

[0036] The bottom of the paint tank 3 is fixedly connected to a U-shaped frame 25. The paint tank 3 and the U-shaped frame 25 are both rotationally connected to a stirring shaft 26 through a sealed bearing. The bottom end of the stirring shaft 26 is fixedly connected to the driving end of a servo motor 27. The servo motor 27 is fixedly installed at the bottom of the U-shaped frame 25. A set of third sprockets 28 are respectively fixedly sleeved on the outer wall of the stirring shaft 26 and the outer wall of the transmission rod 22. The two sets of third sprockets 28 are both engaged with a third chain 29. During use, starting the servo motor 27 drives the stirring shaft 26 to rotate. The stirring shaft 26 rotates and drives the transmission rod 22 to rotate under the transmission of the two sets of third sprockets 28 and the third chain 29.

[0037] A feed pipe 30 is connected to the upper end position of the outer wall of the paint tank 3. A sealing cover is threadedly connected to the feed pipe 30. A discharge pipe 31 is connected to the bottom of the paint tank 3. A valve is installed on the discharge pipe 31. During use, the sealing cover on the feed pipe 30 is rotated and removed, and paint can be added into the paint tank 3. When the painting work is completed, the valve on the discharge pipe 31 is opened, and the paint in the paint tank 3 is discharged through the discharge pipe 31, which is convenient for recycling.

[0038] A plurality of stirring blades 32 are fixedly connected to the outer wall of the stirring shaft 26. The stirring blades 32 are fixedly connected to a scraping plate 33. The scraping plate 33 is slidably attached to the inner wall of the paint tank 3. The rotation of the stirring shaft 26 drives the stirring blades 32 and the scraping plate 33 to rotate. The rotation of the stirring blades 32 continuously stirs the paint in the paint tank 3 to prevent the paint from precipitating. Since the scraping plate 33 is slidably attached to the inner wall of the paint tank 3, the rotation of the scraping plate 33 continuously cleans the inner wall of the paint tank 3.

[0039] A control switch 34 is fixedly installed on the outer wall of the paint tank 3. When the device is used, a suitable external power supply is required. The control switch 34 is electrically connected to the electric push rod 212, the paint pump 8, and the servo motor 27 through wires respectively. The operation of the electric push rod 212, the paint pump 8, and the servo motor 27 can be controlled through the control switch 34.

[0040] Working principle of the present invention: When in use, according to the different heights of the motor housing to be painted, rotate the threaded fixing member 506 so that the threaded fixing member 506 disengages from the threaded hole formed in the L-shaped block 503. At this time, the screw rod 504 can be slid up and down, and thus the distance between the pressing block 505 and the moving plate 17 (at this time, the top end of the moving plate 17 abuts against the L-shaped frame 15, as shown in the attached Figure 1 figure) can be adjusted, and then the range of downward movement of the pressing block 505 can be adjusted. Then, rotate the threaded fixing member 506 again so that the threaded fixing member 506 is threadedly connected to both the threaded hole formed in the L-shaped block 503 and the screw rod 504, so as to make the connection stable. Since the downward movement of the pressing block 505 drives the downward movement of the moving plate 17, the downward movement of the pressing block 505 will drive the downward movement of the third pipe 12, and the downward movement of the third pipe 12 will drive the downward movement of the spray head 13. When the pressing block 505 moves down to the lowest position and the spray head 13 moves down to the lowest position, the lowest point of the spraying range of the spray head 13 is flush with the lowest point of the motor housing to be painted. Thus, the range of up and down movement of the spray head 13 can be controlled to ensure that the paint sprayed by the spray head 13 moving up and down during the painting process is evenly sprayed on all positions of the motor housing, and thus the uniform painting of the motor housing is completed;

[0041] When painting, start the paint pump 8 to extract the paint in the paint tank 3, and draw the paint into the spray head 13 through the first pipe 9, the second pipe 10, the spring pipe 13 and the third pipe 12, and finally spray it out from the spray head 13 and onto the outer wall of the motor housing to be processed; and during the painting process, it is inevitable that the paint will drip on the outer wall of the motor housing. Since there is no turntable or tray at the bottom of the motor housing, the paint will directly pass through the through hole 4 and flow back into the paint tank 3, which can reduce the waste of paint; if necessary, a filter screen can be installed at the through hole 4, as shown in the attached Figure 6 figure, to filter the dripping paint;

[0042] During painting, starting the servo motor 27 simultaneously will drive the stirring shaft 26 to rotate. The rotation of the stirring shaft 26 will drive the stirring blades 32 and the scraping plate 33 to rotate. The rotation of the stirring blades 32 will continuously stir the paint in the paint tank 3 to prevent the paint from precipitating. Since the scraping plate 33 slides and fits against the inner wall of the paint tank 3, the rotation of the scraping plate 33 will continuously clean the inner wall of the paint tank 3. At the same time, the stirring shaft 26 rotates and, under the driving action of the two sets of sprockets three 28 and the chain three 29, will drive the transmission rod 22 to rotate. The rotation of the transmission rod 22 and under the driving of the two sets of sprockets two 23 and the chain two 24 will drive the rotating column 201 to rotate. The rotation of the rotating column 201 will drive the top plate 202 to rotate, and the rotation of the top plate 202 will drive the clamped motor housing to rotate. At the same time, the rotating column 201 rotates and, under the driving action of the two sets of sprockets one 6 and the chain one 7, will drive the reciprocating lead screw 501 to rotate. The rotation of the reciprocating lead screw 501 will drive the L-shaped block 503 to move up and down along the guide rod one 507. When the L-shaped block 503 moves down, it will drive the pressing block 505 to move down. After the pressing block 505 moves down and contacts the moving plate 17, it will drive the moving plate 17 to move down, and the compressed spring 18 will be further compressed. The downward movement of the moving plate 17 will drive the spray head 13 to move down. When the L-shaped block 503 moves up, the compressed spring 18 will drive the moving plate 17 to move up and reset. The upward movement and reset of the moving plate 17 will drive the spray head 13 to move up and reset. Thus, during the painting process, the spray head 13 continuously moves up and down and, in cooperation with the rotation of the motor housing, can evenly paint the motor housing.
