[0002] An electric motor (commonly known as a "motor") is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. It is divided into electric motors (symbolized by M) and generators (symbolized by G). During the production of electric motors, the motor housing will be painted to increase the corrosion resistance of the motor, and it can also better identify the motor to prevent misjudgment.

[0003] As disclosed in a Chinese patent document, a coloring device for producing motor casings (Announcement No.: CN115532498A) includes a shell, a first motor is provided at the bottom of the shell, the output end of the first motor passes through the shell and extends into the interior thereof, a workbench is provided inside the shell, a lifting column is provided inside the workbench, a support box is provided at the bottom of the lifting column, second threaded rods are provided on both sides of the lifting column, a rotating mechanism is provided at the bottom of the second threaded rod, a support column is provided on one side of the second threaded rod, a second second fixing box is provided at the bottom of the support column, the second fixing box is fixedly connected to the bottom end surface of the workbench, two moving mechanisms are symmetrically provided inside the second second fixing box, the end of the support column away from the second second fixing box is fixedly connected to the first fixing box, a limiting plate is provided on the side of the first fixing box close to the lifting column, a fixed block is provided on the top of the first fixing box, a movable mechanism is provided inside the fixed block, and a spray gun is provided at the bottom of the fixed block.

[0004] Although the above-mentioned coloring device for the production of motor casings has achieved "the effect of lifting and lowering the motor casing after the motor casing is placed through the rotating mechanism, so as to facilitate the subsequent fixing and clamping operation of the motor casing, and the moving mechanism can adjust the distance between the two limit plates, so as to be able to clamp the motor casings of different sizes, cooperate with the rotating motor and the rotating block, and then the motor after fixation can be turned over, so that when the motor casing is colored, the coloring can be complete, thereby improving the coloring quality", whenever the size of the motor casing needs to be adjusted, the paint spraying device needs to be manually adjusted to adapt to the new motor casing, and the production line must be stopped for manual testing during the adjustment process.

The switching component 203 is rotatably connected to the inside of the fixed platform 202. The outer wall of the switching component 203 is provided with a reciprocating guide rail 2031, and the outer wall of the switching component 203 is slidably connected to the sliding block 2032. The sliding block 2032 is slidably connected to the outer wall of the switching component 203 through the reciprocating guide rail 2031. The sliding block 2033 is fixedly connected to the top of the sliding block 2032, and one end of the T-shaped block 2033 is fixedly connected to the half rack 2034.

[0039] A motor 204 is fixedly connected to the upper middle part of the support platform 201 , and a turntable 205 is fixedly connected to the output end of the motor 204 . The turntable 205 includes side teeth 2051 , inner teeth 2052 , a connecting plate 2053 , a rotating shaft 2054 , a rotating shaft 2054 , and a second gear 2055 .

[0040] The lower part of the turntable 205 is fixedly connected with side teeth 2051 and inner teeth 2052, and the side teeth 2051 and inner teeth 2052 are coaxial, the upper part of the piston chamber 305 is fixedly connected with a connecting plate 2053, the upper part of the connecting plate 2053 is rotatably connected with two groups of rotating shafts 2054, the outer wall of the rotating shaft 2054 is fixedly connected with a rotating ring 207, and the outer wall of each group of rotating shafts 2054 is fixedly connected with a second gear 2055.

[0041] The second gear 2055 is adapted to the half rack 2034, and a cleaning spray assembly 206 is fixedly connected above each set of rotating shafts 2054. The cleaning spray assembly 206 includes a paint spray nozzle 2061, a cleaning slider 2062, a sandblasting nozzle 2063, a first return spring 2064, a first connecting pipe 2065, a first piston sleeve 2066, a double-headed piston 2067, and a ventilation pipe 2068.

[0044] The above scheme is adopted: when the motor housing is placed on top of the electromagnetic fixing disk 301, if the weight does not meet the requirement, the first piston head 307 cannot push open the wedge block 310, thereby preventing the first gear 2035 from being misaligned with the side tooth 2051. When the motor housing is placed on top of the electromagnetic fixing disk 301, the gas inside the fixing sleeve 302 will also pass through the inside of the connecting plate 2053 from the vent pipe 2068, and move the double-headed piston 2067 to one side from the inside of the first piston sleeve 2066, and then the cleaning slider 2062 is retracted inwardly through the first connecting pipe 2065. The extension distance of the cleaning slider 2062 can be adjusted according to the size of the motor housing above the electromagnetic fixing disk 301 to prevent the small motor housing from not being swept and the large motor housing from being scratched.

[0045] like Figure 7-8As shown, the interior of the lower inner cavity 104 is fixedly connected with a fixing sleeve 302, the interior of the fixing sleeve 302 is slidably connected with an electromagnetic fixing disk 301, the interior of the fixing sleeve 302 is also provided with a ventilation pipe 2068, the upper flip of the fixing sleeve 302 is fixedly connected with a second return spring 303, the other end of the second return spring 303 is fixedly connected to the bottom of the electromagnetic fixing disk 301, second connecting pipes 304 are provided on both sides of the interior of the fixing sleeve 302, a piston cavity 305 is provided inside the support column 106, the other end of the second connecting pipe 304 is connected to the interior of the piston cavity 305, the interior of the piston cavity 305 is slidably connected with a center column 306, and the top of the center column 306 is fixedly connected with a first piston head 307.

[0046] A second piston head 314 is fixedly connected to the top of the first piston head 307, a center sleeve 313 is fixedly connected to the inside of the support column 106, the second piston head 314 is slidably connected to the inside of the center sleeve 313, two groups of second piston sleeves 315 are provided inside the support column 106, connecting rods 311 are rotatably connected to both sides of the support column 106, the second piston sleeve 315 is communicated with the center sleeve 313, a third piston head 316 is slidably connected to the inside of the second piston sleeve 315, the other end of the connecting rod 311 is rotatably connected to one end of the third piston head 316, a fixing ring 312 is rotatably connected to the outer wall of one side of the switching component 203, and the other end of the connecting rod 311 is slidably connected to the inside of the fixing ring 312;

[0047] The support column 106 is fixedly connected to side plates 308 on both sides, and the support column 106 is slidably connected to wedge blocks 310 on both sides. One side of the wedge block 310 is fixedly connected to a limiting spring 309, and the other side of the limiting spring 309 is fixedly connected to one side of the side plate 308.

[0048] The above scheme is adopted: when the motor housing is painted, there will be motor housings of different models and sizes. When a large motor housing is to be painted, the large motor housing is placed above the electromagnetic fixing disk 301. Due to the large weight of the large motor housing, the electromagnetic fixing disk 301 will move downward under the pressure of the large motor housing. The gas inside the fixing sleeve 302 enters the piston chamber 305 through the second connecting pipe 304 under the pressure of the electromagnetic fixing disk 301, and the first piston head 307 pushes the gas inside the center sleeve 313 upward, and pushes the third piston head 316 inside the fixing ring 312, so that the third piston head 316 is pressed downward with the connecting rod 311, and the other end of the connecting rod 311 moves with the fixing ring 312 toward the direction of the inner teeth 2052. At this time, due to the smaller diameter of the inner teeth 2052, the rotation speed of the switching component 203 is slowed down while the rotation speed of the cleaning and spraying component 206 remains unchanged, so that the large motor housing can obtain better cleaning and painting effects.

[0049] The working principle and use process of the present invention:

[0050] Step 1: When you want to paint the motor housing, pull the protective door 102 on one side of the protective housing 101, place the motor housing on top of the electromagnetic fixing plate 301 inside the upper inner cavity 105, and then fix the motor housing by magnetic force;

[0051] Step 2: After the motor housing is fixed, the protective door 102 is closed, and the motor 204 above the support column 106 is started. The motor 204 drives the turntable 205 to rotate, and then the inner gear 2052 drives the switching component 203 to rotate through the first gear 2035. The rotation of the switching component 203 can make the sliding block 2032 reciprocate along the reciprocating guide rail 2031. When the sliding block 2032 slides, the half rack 2034 is driven to slide through the T-shaped block 2033;

[0052] Step 3: When the connecting plate 2053 rotates, the cleaning spray assembly 206 is driven to rotate together through the rotating shaft 2054, and then the sandblasting nozzle 2063 on one side of the cleaning spray assembly 206 will first sandblast the motor housing. During the sandblasting process, the switching assembly 203 brings the half rack 2034 to continuously approach the second gear 2055. When the second gear 2055 and the half rack 2034 are meshed with each other, the cleaning spray assembly 206 can be rotated ninety degrees.

[0053] Step 4: After the rotation is completed, the cleaning slider 2062 will contact the motor housing to clean the motor housing and remove the excess sand from the sandblasting stage to facilitate the subsequent painting. As the switching component 203 continues to rotate, the half rack 2034 is meshed with the second gear 2055 again. At this time, the cleaning spray component 206 rotates 90 degrees again, and the paint spray head 2061 sprays paint on the motor housing under the control of the console 103.

[0054] Step 5, after the paint is sprayed, the half rack 2034 meshes with the second gear 2055 again, so that the cleaning spray assembly 206 rotates 90 degrees again. At this time, the intercepting plate 318 rotates and faces the direction of the electromagnetic fixing disk 301. At this time, the intercepting plate 318 cooperates with the baffle 317 to rotate with the electromagnetic fixing disk 301. At this time, the paint residue on the motor housing will be thrown out under the rotation of the electromagnetic fixing disk 301, so that the coloring is more uniform and the paint on the motor housing can be dried;

[0055] Step 6, when the motor housing is painted, there will be motor housings of different models and sizes. When you want to paint a large motor housing, place the large motor housing above the electromagnetic fixing disk 301. Due to the large weight of the large motor housing, the electromagnetic fixing disk 301 will move downward under the pressure of the large motor housing. The gas inside the fixing sleeve 302 enters the piston chamber 305 through the second connecting pipe 304 under the pressure of the electromagnetic fixing disk 301, and the first piston head 307 pushes the gas inside the center sleeve 313 upward, and pushes the third piston head 316 inside the fixing ring 312, so that the third piston head 316 is pressed downward with the connecting rod 311, and the other end of the connecting rod 311 moves with the fixing ring 312 toward the direction of the inner teeth 2052. At this time, due to the smaller diameter of the inner teeth 2052, the speed of the switching component 203 is slowed down while the speed of the cleaning and spraying component 206 remains unchanged, so that the large motor housing can obtain better cleaning and painting effects;

[0056] Step seven, when the motor housing is placed on top of the electromagnetic fixing disk 301, if the weight does not meet the requirement, the first piston head 307 cannot push open the wedge block 310, thereby preventing the first gear 2035 from being misaligned with the side tooth 2051. When the motor housing is placed on top of the electromagnetic fixing disk 301, the gas inside the fixing sleeve 302 will also pass through the inside of the connecting plate 2053 from the vent pipe 2068, and move the double-headed piston 2067 to one side from the inside of the first piston sleeve 2066, and then the cleaning slider 2062 is retracted inwardly through the first connecting pipe 2065. The extension distance of the cleaning slider 2062 can be adjusted according to the size of the motor housing above the electromagnetic fixing disk 301 to prevent the small motor housing from not being swept and the large motor housing from being scratched.
