[0002] Three-phase asynchronous motors are widely used in driving various types of mechanical equipment and in multiple production fields such as industry and agriculture due to their good operating performance, low price, and easy maintenance. In order to improve the electrical performance of the motor, the motor surface needs to be painted, so a surface treatment device for the three-phase asynchronous motor is required.

[0003] Before painting a three-phase asynchronous motor, the motor needs to be hung above the paint room. Because the motor is prone to shaking when hung, the motor needs to be stabilized before painting. After the motor is stabilized, the staff needs to manually turn the hook of the hanging crane to make the motor rotate. Then the staff can hold the nozzle of the paint sprayer to paint the motor.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0032] Example 1: A surface treatment device for a three-phase asynchronous motor, such as Figure 1-Figure 4As shown, it includes a paint booth 1, an electric slide rail 11, a fixing member 12, a first motor 13, a connecting member 14, a first telescopic member 15, a rotating member 16, a lifting member 17, a first guide rail 18, a force storage spring 19, a sliding member 101, a trapezoidal block 110, a second guide rail 111 and a pressure spring 112. A feeding door is provided on the right side of the paint booth 1, and a discharging door is provided on the left side of the paint booth 1. The electric slide rail 11 is fixedly connected to the top of the paint booth 1, the sliding member 101 is slidably connected to the electric slide rail 11, the three-phase asynchronous motor is suspended directly below the sliding member 101, and a straight slot is provided directly below the motor. The fixing member 12 is fixedly connected to the inner bottom of the paint booth 1, the first motor 13 is fixedly connected directly above the fixing member 12, the connecting member 14 is fixedly connected to the output shaft of the first motor 13, the first telescopic member 15 is fixedly connected above the connecting member 14, and the rotating member 16 is fixedly connected to the first telescopic member 15 The telescopic end of the first telescopic member 15 is fixedly connected to both sides of the telescopic end of the first telescopic member 15, and the trapezoidal blocks 110 are slidably connected to the second guide rails 111. The trapezoidal blocks 110 are squeezed and matched with the slots of the three-phase asynchronous motor. The pressure springs 112 are respectively wound on the second guide rails 111. One end of the pressure springs 112 is fixedly connected to the second guide rails 111, and the other end of the pressure springs 112 is fixedly connected to the trapezoidal blocks 110. A vertical groove is provided on the inner rear side of the paint booth 1. The first guide rail 18 is fixedly connected in the vertical groove. The lifting member 17 is slidably connected to the first guide rail 18. An inclined surface is provided on the right side of the lifting member 17. The inclined surface is squeezed and matched with the sliding member 101. The lifting member 17 is snap-fitted with the rotating member 16. The storage spring 19 is wound on the first guide rail 18. One end of the storage spring 19 is fixedly connected to the lifting member 17, and the other end of the storage spring 19 is fixedly connected to the paint booth 1.

[0033] After the three-phase asynchronous motor is assembled, it is usually necessary to paint it. In order to make the paint on the motor surface even, the motor needs to be rotated. Before starting to paint, the electric slide rail 11 is controlled to make the slide 101 located at the feed door. The staff can hang the unpainted motor directly under the slide 101, and then control the electric slide rail 11 to drive the slide 101 to move to the left. In the process of the slide 101 moving to the left, the slide 101 will gradually contact and squeeze the inclined surface of the lifting member 17. Under the squeezing action of the slide 101, the lifting member 17 will be lifted upward, the first guide rail 18 is stretched, and the lifting of the lifting member 17 will cause the lower end of the lifting member 17 to gradually contact and squeeze the rotating member. The rotating member 16 is engaged, and the lifting member 17 continues to move upward, which will drive the rotating member 16 to move upward. The upward movement of the rotating member 16 will drive the telescopic end of the first telescopic member 15 to move upward. The upward movement of the telescopic end of the first telescopic member 15 will drive the trapezoidal block 110 to move upward. The upward movement of the trapezoidal block 110 will gradually contact the slot of the motor, and under the extrusion of the slot, the trapezoidal blocks 110 all move inward, so that the trapezoidal blocks 110 are engaged in the slot at the bottom of the motor. At this time, the pressure spring 112 is compressed. After the trapezoidal block 110 is engaged in the slot, the electric slide rail 11 is controlled to stop driving the sliding member 101 to move to the right, and then the first motor 13 can be started, so that the first motor 13 drives the connecting member 14 to rotate, and the connecting member The rotation of 14 will drive the first telescopic member 15 and the rotating member 16 to rotate, and the first telescopic member 15 will drive the trapezoidal block 110 to rotate. Because the trapezoidal block 110 is engaged with the motor at this time, the rotation of the trapezoidal block 110 will drive the motor to rotate. When the motor starts to rotate, the staff can hold the paint spray gun to spray paint on the motor. When the painting is completed, the first motor 13 can be turned off, and then the electric slide rail 11 can be controlled to drive the sliding member 101 to move to the right. In the process of the sliding member 101 continuing to move to the right, the sliding member 101 will gradually separate from the lifting member 17. At this time, the sliding member 101 no longer squeezes the lifting member 17, and the stretched storage spring 19 will shrink. The shrinkage of the storage spring 19 will drive the lifting member 17 to move downward and reset, lifting Part 17 moves downward and no longer engages with rotating part 16. Under the action of the gravity of rotating part 16 and trapezoidal block 110, the telescopic end of the first telescopic part 15 will shrink downward. The downward movement of the first telescopic part 15 will drive the trapezoidal block 110 to be pulled out of the slot of the motor. The slot no longer squeezes the trapezoidal block 110, and the compressed pressure spring 112 will extend. The extension of the pressure spring 112 will drive the trapezoidal block 110 to move outward and reset. The sliding part 101 continues to drive the motor that has completed painting to move to the right. Finally, the motor will move to the discharge door on the left side of the paint spraying room 1, and the staff can remove the motor that has been painted. Through the above operation, the three-phase asynchronous motor can rotate during the painting process, which is convenient for the staff to spray paint and makes the paint spraying more uniform.

[0034] Example 2: Based on Example 1, Figure 5 and Figure 6 As shown, a protective mechanism for protecting the motor is also included, which includes a second motor 2, a bidirectional screw 21, a limiter 22, a third guide rail 23, a connecting frame 24, a fourth guide rail 25, a compression spring 26, a protective member 27, an air pump 28, an air guide tube 29, a second telescopic member, an air bag 210, a protective plate 211, a circular baffle 212, a connecting member 14, a telescopic member, a fixing ring 203 and a tension spring 204. The bidirectional screw 21 is rotatably connected to the inside of the connecting member 14, and two front and rear symmetrical connecting frames 24 are both threadedly connected to the bidirectional screw 21. The two limiters 22 are respectively fixedly connected to the bidirectional screw 21, and the limiters 22 are located at the connecting member. On the front and rear sides of 14, the limit members 22 are used to limit the connecting frame 24 from moving too much inward, the fixing ring 203 is fixedly connected to the top of the fixing member 12, and the two third telescopic members 202 symmetrically arranged in the front and rear are fixedly connected to the fixing ring 203, the bidirectional screw 21 is squeezed and matched with the telescopic end of the third telescopic member 202, the tension spring 204 is connected to the inside of the third telescopic member 202, one end of the tension spring 204 is fixedly connected to the telescopic end of the third telescopic member 202, and the other end of the tension spring 204 is fixedly connected to the fixed end of the third telescopic member 202, the second telescopic member 201 is fixedly connected to the rear side of the fixed end of the third telescopic member 202 at the rear, and the second motor 2 is fixedly connected The second telescopic member 201 is connected to the telescopic end, the rear end of the bidirectional screw 21 is fixedly connected to the output shaft of the second motor 2, the third guide rail 23 is slidably connected between the two connecting frames 24, the third guide rail 23 passes through the inside of the connecting member 14, the fourth guide rail 25 is slidably connected to the connecting frame 24, the protective plate 211 is fixedly connected to the outer end of the fourth guide rail 25, the compression spring 26 is respectively wound on the fourth guide rail 25, one end of the compression spring 26 is fixedly connected to the connecting frame 24, and the other end of the compression spring 26 is fixedly connected to the protective plate 211, the circular baffle 212 is fixedly connected to the rear protective plate 211, and the circular baffle 212 is used to adjust the three-phase The fan of the stepper motor is shielded, and the outer ring of the circular baffle 212 is a raised ring, which can make the fixing part 12 more closely attached to the protective net of the motor. The protective part 27 is fixedly connected above the front protective plate 211. The protective part 27 is hollow. The protective part 27 is used to protect the output shaft of the motor. The airbag 210 is fixedly connected to the inner wall of the protective part 27. The airbag 210 is set at a position close to the output shaft of the motor. The air pump 28 is fixedly connected to the front side of the front protective plate 211. The air duct 29 is connected between the protective part 27 and the air pump 28. The air duct 29 connects the airbag 210 with the air pump 28, and the air pump 28 supplies air to the airbag 210 through the air duct 29.

[0035] A protective net is provided on the outside of the motor, so when the motor is being painted, paint may enter the motor through the protective net and affect the insulation and heat dissipation performance of the motor, and the output end of the motor does not need to be painted, so when the motor is being painted, the protective net and the output shaft of the motor need to be covered. Before painting the motor, first start the second motor 2, the second motor 2 will drive the bidirectional screw 21 to rotate, the rotation of the bidirectional screw 21 will drive the connecting frame 24 to move inward, the movement of the connecting frame 24 will drive the fourth guide rail 25 to move inward, the inward movement of the fourth guide rail 25 will drive the protective plate 211 to move forward, and the forward movement of the protective plate 211 will drive the circular baffle 212 to move forward. When the fourth guide rail 25 moves forward, the circular baffle 212 will cover the protective net of the motor and cover the protective net of the motor. When the fourth guide rail 25 moves inward, it will also drive the protective member 27 to move backward. The protective member 27 moves backward and covers the output shaft of the motor. The airbag 210 will also move backward. At this time, the air pump 28 can be started. The air pump 28 will input gas to the airbag 210 through the air guide tube 29. The airbag 210 will expand. The expansion of the airbag 210 will fit tightly against the output shaft of the motor, so that the output shaft of the motor is completely isolated from the outside world. The connecting frame 24 continues to move inward and will gradually contact the limit member 22. The limit member 22 will block the connecting frame 24 so that the connecting frame 24 cannot continue to move inward. At this time, the circular baffle 212 has been in contact with the motor and the protective member 27 has also covered the output shaft of the motor. The protective plate 211 will not be driven to move inward, and the compression spring 26 will be stretched, so that the circular baffle 212 is more tightly attached to the fan of the motor, and the rear end of the protective member 27 is more tightly attached to the front side of the motor. After the fan and output shaft of the motor are wrapped, the staff can paint the motor. After the painting is completed, the air pump 28 is started. The air pump 28 extracts the gas in the air bag 210 through the air guide tube 29, and then the second motor 2 is started, so that the second motor 2 drives the limit member 22 to rotate in the opposite direction to the previous direction. The rotation of the third guide rail 23 will drive the connecting frame 24 to move outward. The movement of the connecting frame 24 will drive the telescopic end of the second telescopic member to move backward and reset, the outward movement of the connecting frame 24 will drive the fourth guide rail 25 to move outward, the outward movement of the fourth guide rail 25 will drive the protective plate 211 to move backward, the protective plate 211 will drive the circular baffle 212 to move backward and reset, the movement of the protective plate 211 will also drive the protective member 27 and the airbag 210 to move forward and reset, then the electric slide rail 11 can be controlled to drive the sliding member 101 to move to the left, the motor that has finished painting will be moved out of the discharge door of the paint spraying room 1, so that the fan and the output shaft of the motor can be blocked before painting to prevent these two components from being stained with paint during the painting process and affecting the performance of the motor.

[0036] like Figure 7As shown, there is also a limiting mechanism for limiting the motor, which includes an extrusion member 3, a wedge member 31, an elastic telescopic member 32, a limiting member 33 and a telescopic spring 321. The extrusion member 3 is fixedly connected to the middle position of the front side of the lifting member 17, and the two elastic telescopic members 32 are respectively fixedly connected to the bottom of the sliding member 101. A telescopic spring 321 is provided in the elastic telescopic member 32, and one end of the telescopic spring 321 is fixedly connected to the fixed end of the elastic telescopic member 32, and the other end of the telescopic spring 321 is fixedly connected to the telescopic end of the elastic telescopic member 32. The limiting members 33 are all fixedly connected below the telescopic end of the elastic telescopic member 32. The limiting member 33 is used to limit the swing of the motor, and the wedge member 31 is fixedly connected to the left side of the telescopic end of the two elastic telescopic members 32. The wedge member 31 is squeezed and matched with the extrusion member 3.

[0037] When the staff hangs the motor from the feed door to just below the sliding member 101, the staff usually does not stabilize the motor, resulting in the motor shaking during the process of moving from the feed door of the paint spraying room 1 to just above the fixing member 12. The shaking of the motor will cause the upward moving trapezoidal block 110 to be unable to smoothly snap into the slot at the bottom of the motor when the motor moves to just above the fixing member 12, making the trapezoidal block 110 unable to drive the motor to rotate. Therefore, it is necessary to stabilize the motor before painting. When the motor is hung from the feed door to just below the sliding member 101, the telescopic spring 321 is in a naturally extended state, and the limiting member 33 is just located at the motor There is a very narrow gap between the limiting member 33 and the motor directly above it. When the motor shakes, the top of the motor will contact the limiting member 33, and the limiting member 33 will limit the shaking motor so that the motor remains stable during movement. When the motor moves to the top of the fixing member 12, the sliding member 101 squeezes the lifting member 17 and moves it upward. The upward movement of the lifting member 17 will drive the extruding member 3 to move upward, and the extruding member 3 will squeeze the wedge member 31. Under the squeezing action of the extruding member 3, the wedge member 31 will move upward, and the upward movement of the wedge member 31 will drive the telescopic end of the elastic telescopic member 32 to move upward, and the upward movement of the elastic telescopic member 32 will drive The limiting member 33 moves upward, and the telescopic spring 321 will be compressed. After the limiting member 33 moves upward, the motor can be rotated and the motor can be painted. After the painting is completed, the sliding member 101 will drive the motor to move to the left, and the sliding member 101 will gradually separate from the lifting member 17 when it moves to the left. In this process, the wedge member 31 will continue to move to the left and slide out from above the extrusion member 3. After the lifting member 17 is separated from the sliding member 101, the lifting member 17 and the extrusion member 3 will move downward to reset. At this time, the compressed telescopic spring 321 will stretch. Under the action of the elastic force of the telescopic spring 321 and the gravity of the limiting member 33 and the wedge member 31, the elastic The telescopic end of the telescopic member 32 will move downward and reset. The movement of the elastic telescopic member 32 will drive the wedge-shaped member 31 and the limiting member 33 to move downward and reset as well. The limiting member 33 will be re-located directly above the motor. A gap will be left between the limiting member 33 and the painted motor. The motor that is disengaged from the trapezoidal block 110 will remain stable while continuing to move to the left. Therefore, the limiting member 33 will not contact the painted motor, preventing the limiting member 33 from rubbing off the undried paint on the motor. The painted motor will be moved out of the discharge port of the paint spraying room 1. In this way, the motor can be stabilized before painting, so that the trapezoidal block 110 can be smoothly engaged with the slot at the bottom of the motor.

[0038] like Figures 8-10As shown, it also includes a lifting mechanism for lifting one side of the motor, and the lifting mechanism includes a rack 4, a gear 41 and a connecting block 42. The rack 4 is fixedly connected to the left side of the rear connecting frame 24, and the connecting block 42 is rotatably connected to the inside of the connecting member 14. A circular hole is opened on the connecting block 42, and the bidirectional screw 21 passes through the connecting block 42 through the circular hole. The bidirectional screw 21 is rotatably connected to the connecting block 42, and the gear 41 is fixedly connected to the left side of the connecting block 42. The gear 41 and the rack 4 are engaged with each other.

The front protective plate 211 will be lifted, and the rear protective plate 211 will drop. The protective member 27 will be lifted. At this time, the protective member 27 has been sleeved on the motor output shaft. The upward lifting of the protective member 27 will drive the front of the motor to lift upward, thereby lifting the front of the motor and lowering the rear of the motor. The motor will be in a state where the front end is tilted upward. State, at this time the bottom of the motor will be exposed to the staff's field of vision, the staff can paint the motor, after the painting is completed, the second motor 2 will drive the connecting frame 24 to move outward, the connecting frame 24 moves outward to drive the rack 4 to move backward, the rack 4 moves backward to drive the gear 41 to rotate clockwise, the gear 41 will drive the connecting block 42 to rotate, the connecting block 42 rotates to drive the third guide rail 23 to rotate clockwise with the connecting block 42 as the center of the circle to reset, the clockwise rotation of the third guide rail 23 will drive the front connecting frame 24 to move downward, the rear The connecting frame 24 on the side is lifted upward, the front protective plate 211 will move downward and reset, the rear protective plate 211 will move upward and reset, the protective part 27 will also move downward, the protective part 27 will lead the front of the motor to move downward and reset, and the rear of the motor will move upward and reset, so that the front of the motor moves downward, the rear of the motor is lifted upward, and the motor is reset. After the motor is reset, the painted motor can be moved out.
