Description

Technical Field

[0001] The present invention relates to the field of detection devices, and more particularly to a synchronous motor coil detection device. Background Art

[0002] A synchronous motor is an AC motor characterized by the fact that the rotation speed of the rotor is the same as the speed of the rotating magnetic field generated by the stator, that is, there is a fixed relationship between the rotor speed and the grid frequency. The coils in a synchronous motor are mainly divided into two parts: the stator coil and the rotor coil. They each have different functions and work together to achieve normal operation of the motor. Common motor coil shapes include cylindrical, annular, flat and square.

[0003] In the motor manufacturing process, the coil is one of the key components. For cylindrical coils, the flatness of its inner and outer walls directly affects the overall performance of the motor. However, in actual production, the coils may become uneven due to the following reasons: 1. Whether it is wound manually or produced by an automatic winding machine, it is impossible to completely avoid uneven gaps or local deformation between the wires; 2. After long-term operation, factors such as thermal expansion and contraction and mechanical vibration may also cause bulging on the coil surface.

[0004] To ensure efficient operation and extend the service life of the motor, the flatness of the coil must be strictly inspected. Traditional inspection methods mainly include manual visual inspection and simple measuring tools (such as vernier calipers). However, since the coils are closely arranged in circles, long-term observation will cause visual fatigue to the inspector. In particular, it is difficult for the human eye to accurately identify subtle uneven areas, which can easily be missed. This not only reduces the inspection effect, but also causes safety risks caused by missed coils, thereby reducing safety. Summary of the Invention

[0005] In response to the problems existing in the prior art, the purpose of the present invention is to provide a synchronous motor coil detection device that can simultaneously detect the flatness of the inner and outer walls of the coil. When there is a bulge, it can control the corresponding alarm to turn on to remind the inspector, and enable the inspector to clearly know the location of the defect, thereby greatly improving the detection effect and reducing the possibility of missed detection.

A fixed rod is rotatably installed on the top of the reciprocating screw rod inside the coil body, and an L-shaped rod is fixedly installed on the top of the connecting plate inside the coil body, and the L-shaped rod is slidably installed with the connecting plate inside the coil body.

[0012] Furthermore, elastic telescopic tubes are fixedly installed near the top on the opposite sides of the two groups of connecting plates, and spray tubes are fixedly installed on the output ends of the two groups of elastic telescopic tubes. The other ends of the two groups of spray tubes pass through the adjacent U-shaped plates toward the coil body, and the opposite ends of the two groups of U-shaped plates are respectively facing the inner wall and outer wall of the coil body.

[0013] Furthermore, round blocks are fixedly installed on the opposite ends of the two groups of elastic telescopic tubes, and the two groups of round blocks are sleeved on the outer walls of the adjacent spray tubes. Round tubes are threadedly installed on the outer walls of the two groups of round blocks, and the two groups of round blocks are arranged non-contact with the adjacent U-shaped plates.

[0014] Furthermore, movable rods are evenly fixedly installed on the rod wall of the fixed rod, and the other end of each group of movable rods is rotatably installed with a roller.

[0015] Furthermore, a top plate is provided on the upper side of the coil body, a movable plate is provided on the upper side of the top plate, the top plate and the movable plate are both sleeved on the rod wall of the vertical rod, and a spring 2 is fixedly installed between the top plate and the movable plate.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) This solution rotates the coil body so that the two groups of rollers roll on its inner and outer walls respectively. When the rollers encounter a bulge, they move, so that the two adjacent groups of contact blocks contact and control the corresponding alarms to give an alarm reminder, thereby playing the role of simultaneously detecting the inner and outer walls of the coil body. During the detection process, through the setting of the alarms on the left and right sides, the inspector can clearly know whether it is a bulge on the inside or outside of the coil body, so that the inspector can distinguish the coil bodies with bulges on different sides, avoiding the visual fatigue of the inspector caused by the characteristics of the coil body in the past, thereby greatly improving the detection effect and further improving the safety of the use of the coil body.

[0022] (2) This solution can drive the fixed blocks on the two sets of reciprocating screws to move up and down during the rotation process. The fixed blocks will drive the spring 1 to move up and down synchronously through the connecting plate. The spring 1 will drive the roller to move up and down through the U-shaped plate. The coil body can rotate slowly while the two sets of rollers roll and move up and down on the inner and outer walls of the coil body. The entire inner and outer wall surface of the coil body can be fully inspected, ensuring that every position can be inspected, improving the coverage of the inspection, and reducing the possibility of missed inspections, thereby effectively improving the inspection effect of the two sets of rollers on the flatness of the inner and outer walls of the coil body.

[0023] (3) In this solution, when the roller encounters a bulge, it will drive the round tube to move, and the round tube will drive the round block to move and squeeze the elastic telescopic tube. The marking paint inside the elastic telescopic tube will be squeezed through the spray tube and sprayed to the bulge on the inner wall or outer wall corresponding to the coil body, which can leave a mark on the bulge on the coil body and play a marking role. The bulge will be in the vertical direction of the mark, which can enable subsequent inspectors to quickly and intuitively locate the specific defect position, reducing the time for finding defects, improving the overall detection efficiency, and thus improving the efficiency of maintenance.

[0032] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only 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 ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 6 A synchronous motor coil detection device includes a base 1, two sets of reciprocating screw rods 2 are rotatably installed on the top of the base 1, and a belt is installed between the two sets of reciprocating screw rods 2;

[0034] Also includes:

[0035] The detection component includes fixed blocks 3 respectively threadedly installed on the reciprocating screw 2, and connecting plates 4 are fixedly installed on the opposite sides of the two groups of fixed blocks 3. U-shaped plates 5 are provided on the opposite sides of the two groups of connecting plates 4. Springs 6 are fixedly installed between the two groups of U-shaped plates 5 and the adjacent connecting plates 4, and rollers 7 are rotatably installed on the opposite sides of the two groups of U-shaped plates 5. A coil body 8 is provided in contact between the two groups of rollers 7, and a circular plate 9 is provided in contact with the bottom of the coil body 8. The circular plate 9 is rotatably installed with the reciprocating screw 2, and a vertical rod 14 is fixedly installed on one side of the top of the base 1. The fixed block 3 outside the coil body 8 is slidably installed on the rod wall of the vertical rod 14, and alarm components are provided on the opposite sides of the two groups of connecting plates 4.

[0036] The alarm assembly includes fixed tubes 15 fixedly mounted on opposite sides of the two sets of connecting plates 4, with mounting blocks 16 threadedly mounted in the two sets of fixed tubes 15. Elastic rods 17 are fixedly mounted on opposite ends of the two sets of mounting blocks 16. Contact blocks 18 are fixedly mounted on the other ends of the two sets of elastic rods 17 and the side walls of the adjacent U-shaped plates 5. Two sets of alarms 19 are fixedly mounted on the top of the base 1, and the two adjacent sets of contact blocks 18 are connected in series with one set of alarms 19.

[0037] A gear ring 10 is fixedly installed at the bottom of the circular plate 9, a gear 11 is fixedly installed on the rod wall of the reciprocating screw rod 2, a gear 2 12 is meshed between the gear 11 and the gear ring 10, and the gear 2 12 is rotatably installed with the top of the base 1. A small motor 13 is fixedly installed at the bottom of the base 1, and the output shaft of the small motor 13 is fixedly installed with the bottom end of one group of reciprocating screw rods 2. A fixed rod 27 is rotatably installed on the top of the reciprocating screw rod 2 inside the coil body 8, and an L-shaped rod 33 is fixedly installed on the top of the connecting plate 4 inside the coil body 8. The L-shaped rod 33 is slidably installed with the connecting plate 4 inside the coil body 8.

[0038] First, when the flatness of the coil body 8 needs to be tested, the small motor 13 is turned on, and the output shaft of the small motor 13 will drive the reciprocating screw 2 inside the coil body 8 to rotate. At this time, the reciprocating screw 2 on the left side will drive the reciprocating screw 2 on the right side to rotate synchronously through the belt while rotating. When the reciprocating screw 2 on the left side rotates, it will drive the gear 2 12 to rotate through the gear 1 11. The rotation of the gear 2 12 will drive the circular plate 9 to rotate through the gear ring 10. Through the cooperation of the gear 1 11 and the gear 2 12, the direction of the circular plate 9 can be driven to rotate in the same direction as the left reciprocating screw 2. The direction of rotation of the screw rod 2 is opposite, and the circular plate 9 rotates in the opposite direction, which will drive the coil body 8 to rotate synchronously. At this time, the roller 7 on the left rolls on the inner cavity wall of the coil body 8, and the roller 7 on the right rolls on the outer wall of the coil body 8, so that the side wall of the coil body 8 can be rotated between the two groups of rollers 7. The two groups of contact blocks 18 on the inner side of the coil body 8 are electrically connected to the alarm 19 on the left, and the two groups of contact blocks 18 on the outer side of the coil body 8 are electrically connected to the alarm 19 on the right. When a bulge appears on the inner or outer wall of the coil body 8, the roller 7 will roll on the bulge. When the U-shaped plate 5 moves to the side away from the bulge, the roller 7 will push the U-shaped plate 5 on it to move to the side of the adjacent connecting plate 4 and squeeze the spring 6. When the U-shaped plate 5 moves, it will drive the contact block 18 on it to move synchronously. When the contact block 18 on the U-shaped plate 5 contacts the contact block 18 on the elastic rod 17, the two adjacent groups of contact blocks 18 on the inner and outer sides of the coil body 8 will contact and control the alarms 19 on the left and right sides to be energized and turn on, and alert the staff, which can effectively detect any uneven areas and issue alarms in time, playing a role in line The inner and outer side walls of the coil body 8 are tested simultaneously. During the testing process, if the alarms 19 on both sides do not sound an alarm, it proves that the coil body 8 is in good condition. At the same time, the arrangement of the alarms 19 on the left and right sides allows the inspector to clearly know whether the bulge is on the inner side or the outer side of the coil body 8, so that the inspector can distinguish the coil bodies 8 with bulges on different sides, thus avoiding the visual fatigue of the inspector caused by the characteristics of the coil body 8 in the past, thereby greatly improving the testing effect and further improving the safety of the use of the coil body 8.

[0039] When the two sets of reciprocating screws 2 rotate, the fixed blocks 3 thereon can be driven to move up and down respectively. The fixed blocks 3 can drive the spring 1 6 to move up and down synchronously through the connecting plate 4. The spring 1 6 can drive the roller 7 to move up and down through the U-shaped plate 5. The cooperation of the gear 1 11 and the gear 2 12 can realize that the circular plate 9 drives the coil body 8 to rotate slowly. At this time, the coil body 8 can rotate slowly while the two sets of rollers 7 roll and move up and down on the inner and outer walls of the coil body 8, so as to realize comprehensive detection of the entire inner and outer wall surfaces of the coil body 8, ensuring that every position can be inspected, thereby improving the detection coverage rate and reducing the possibility of missed detection, thereby effectively improving the detection effect of the two sets of rollers 7 on the flatness of the inner and outer walls of the coil body 8;

[0040] By rotating the elastic rod 17 forward and backward to drive the mounting block 16 to rotate in the inner cavity of the fixed tube 15, the mounting block 16 can be driven to move left and right in the inner cavity of the fixed tube 15. At this time, the distance between the contact block 18 on the elastic rod 17 and the contact block 18 on the U-shaped plate 5 can be adjusted. At this time, the distance between the two adjacent groups of coil bodies 8 can be adjusted according to the allowable deviation range of the actual bulge of the coil body 8. Within the normal value, the two groups of coil bodies 8 can be made not to contact. When the normal value is exceeded, the two groups of coil bodies 8 are made to contact to control the corresponding alarm 19 to alarm, which can realize detection tasks that can adapt to different precision requirements, not only improving the sensitivity of detection, but also improving the overall detection quality.

[0041] like Figure 3 and Figure 6 As shown, elastic telescopic tubes 20 are fixedly installed near the top on the opposite sides of the two sets of connecting plates 4, and spray tubes 23 are fixedly installed at the output ends of the two sets of elastic telescopic tubes 20. The other ends of the two sets of spray tubes 23 pass through the adjacent U-shaped plates 5 toward the coil body 8, and the opposite ends of the two sets of U-shaped plates 5 are respectively facing the inner wall and outer wall of the coil body 8.

[0042] The opposite ends of the two groups of elastic telescopic tubes 20 are fixedly installed with round blocks 21, and the two groups of round blocks 21 are sleeved on the outer walls of the adjacent spray tubes 23. Round tubes 22 are threadedly installed on the outer walls of the two groups of round blocks 21. The two groups of round blocks 21 are arranged non-contact with the adjacent U-shaped plates 5.

[0043] The top of the elastic telescopic tube 20 is provided with a sealing cover corresponding to the feed port, and is also provided with an air intake port for the elastic telescopic tube 20 to restore its initial state after being squeezed. The elastic telescopic tube 20 is filled with marking paint, and the marking paint can only be discharged through the spray tube 23. When a bulge appears on the inner wall or outer wall of the coil body 8, the rollers 7 on the inner and outer walls will be squeezed by the bulge when rolling on the bulge and move to the side away from the bulge. The rollers 7 will push the U-shaped plate 5 thereon to move toward one side of the adjacent connecting plate 4 and squeeze the spring 6. In the process of movement of the U-shaped plate 5, when the U-shaped plate 5 moves and contacts the circular tube 22 and continues to move, the U-shaped plate 5 can push the circular tube 22 to drive the round block 21 to move toward one side of the adjacent connecting plate 4, and the round block 21 will squeeze the elastic telescopic tube while moving. 20, the marking paint inside the elastic telescopic tube 20 is squeezed and sprayed through the spray tube 23 to the bulge on the corresponding inner or outer wall of the coil body 8, which can leave a mark on the bulge on the coil body 8 and play a marking role. The bulge will be in the vertical direction of the mark, which can enable subsequent inspectors to quickly and intuitively locate the specific defect position, reducing the time for finding defects, improving the overall detection efficiency, and thus improving the efficiency of maintenance. When the roller 7 moves out from the bulge, under the action of the spring 1 6, the spring 1 6 returns to its initial state and drives the roller 7 to move to its initial position through the U-shaped plate 5. At the same time, under the action of the elastic telescopic tube 20, it will automatically return to its initial state and drive the round block 21 and the round tube 22 to move to their initial positions;

[0044] By rotating the circular tube 22 forward and backward on the outer wall of the round block 21, the circular tube 22 can be moved left and right. At this time, the distance between the circular tube 22 and the U-shaped plate 5 can be adjusted, which increases the flexibility and scope of use, is suitable for use in various application scenarios, and further improves the detection effect.

[0045] like Figure 2 As shown, movable rods 28 are evenly fixedly installed on the rod wall of the fixed rod 27, and the other end of each group of movable rods 28 is rotatably installed with a roller 29.

[0046] A top plate 24 is provided on the upper side of the coil body 8 , and a movable plate 25 is provided on the upper side of the top plate 24 . Both the top plate 24 and the movable plate 25 are sleeved on the rod wall of the vertical rod 14 , and a spring 26 is fixedly installed between the top plate 24 and the movable plate 25 .

[0047] An opening 31 is provided on the top plate 24 to match the inner cavity of the coil body 8 . Each group of rollers 29 is arranged in contact with the inner cavity wall of the opening 31 . The inner cavity of the opening 31 is provided with anti-slip patterns.

[0048] An elastic rope is installed between the rod wall of each group of movable rods 28 and the outer wall of the fixed rod 27. When the coil body 8 needs to be removed, the top plate 24 is pulled upward on the vertical rod 14, and the top plate 24 will squeeze the spring 26. When the top plate 24 moves to the upper side of the fixed rod 27, the top plate 24 is pulled to deflect. The top plate 24 will drive the movable plate 25 to deflect on the vertical rod 14 through the spring 26, so that the top plate 24 moves out of the top of the fixed rod 27. At this time, the coil body 8 is pulled upward from the outer wall of each group of rollers 29 to be taken out. If the rollers 29 exceed the inner diameter of the coil body 8, the movable rod 28 is pressed downward to drive the rollers 29 to deflect to within the inner diameter range of the coil body 8.

[0049] When the coil body 8 needs to be placed on the top of the circular plate 9, it is only necessary to place the bottom of the coil body 8 on the rod wall of each group of movable rods 28 and press down so that each group of rollers 29 moves into the inner cavity wall of the coil body 8. The deflection of each group of movable rods 28 will stretch the elastic rope. At this time, the coil body 8 will slide down along each group of rollers 29 to the top of the circular plate 9. The side wall of the circular plate 9 will be inserted between the two groups of rollers 7, which will play a role in guiding the placement and automatic positioning of the coil body 8. Then, the top plate 24 is pulled again to deflect so that the opening 31 is mounted on the outer side of each group of rollers 29 from the upper right to the bottom. By setting the anti-slip grooves in the inner cavity of the opening 31, it can be achieved that the fixed rod 27 will not rotate while the reciprocating screw rod 2 on the left side rotates, so that the connecting plate 4 on the left side can move up and down stably on the L-shaped rod 33.

[0050] like Figures 4 to 6 As shown, a circular plate 32 is rotatably mounted on the bottom of the top plate 24 , and the circular plate 32 is arranged in contact with the top of the coil body 8 .

[0051] Limit blocks 30 are provided on opposite sides of the top plate 24 and the movable plate 25 , and both sets of limit blocks 30 are fixedly mounted on the vertical rods 14 .

[0052] The distance between the circular tube 22 and the U-shaped plate 5 is smaller than the distance between two adjacent groups of contact blocks 18, and a section of the spraying tube 23 in the inner cavity of the circular tube 22 is retractable.

[0053] When the top plate 24 is pulled to deflect so that the opening 31 is sleeved on the outside of each group of rollers 29, the annular plate 32 will contact the top of the coil body 8, and the elastic force of the spring 26 will make the top plate 24 drive the annular plate 32 to squeeze the coil body 8, so that when the circular plate 9 drives the coil body 8 to rotate, the coil body 8 will rotate at the bottom of the top plate 24 through the annular plate 32. The section of the spray tube 23 passing through the inner cavity of the circular tube 22 is retractable, so that the circular tube 22 will not be affected when pushing the round block 21 to squeeze the elastic telescopic tube 20 to shrink and move.

[0054] Working principle: First, when the coil body 8 is to be inspected, the small motor 13 is turned on. The small motor 13 will drive the two sets of reciprocating screws 2 to rotate. When the two sets of reciprocating screws 2 rotate, they will drive the connecting plate 4 to move up and down through the fixed block 3, so that the U-shaped plate 5 drives the roller 7 to move up and down. Through the cooperation of gear 1 11 and gear 2 12, the circular plate 9 can drive the coil body 8 to rotate slowly, so that the two sets of rollers 7 can roll and move up and down on the inner and outer walls of the coil body 8 respectively, and detect the flatness of the inner and outer walls of the coil body 8. When there are bulges on the inner and outer walls of the coil body 8, the roller 7 will be squeezed to drive the U-shaped plate 5 to move. At this time, the two adjacent groups of contact blocks 18 on one side of the bulge will contact, and the corresponding alarm 19 will be controlled to turn on the alarm reminder. The two sets of alarms 19 can allow the inspector to clear the alarm. It is clear whether the bulge is on the inner wall or the outer wall of the coil body 8. At the same time, when the U-shaped plate 5 moves, it will also squeeze the elastic telescopic tube 20. The elastic telescopic tube 20 will spray the bulge through the spray tube 23 to mark the bulge. The bulge will be in the vertical direction of the mark, allowing the inspector to intuitively see the position of the bulge. The spacing between the two adjacent groups of coil bodies 8 can be adjusted by rotating the elastic rod 17 to drive the mounting block 16 to move. The spacing between the circular tube 22 and the U-shaped plate 5 can be adjusted by rotating the circular tube 22. This is adjusted according to the allowable deviation range of the actual bulge protrusion to improve the adaptability range. When the coil body 8 needs to be removed, pull the top plate 24 upward and deflect it out of the top of the coil body 8. Pull the coil body 8 upward from the outer wall of each group of rollers 29 to remove it.
