Description

Technical Field

[0001] This invention relates to the field of coil testing technology, and more specifically, to a tester for the embedding performance of enameled aluminum wire coils. Background Technology

[0002] In new materials services, the enameled aluminum wire coil embedding performance tester is mainly used to evaluate the mechanical properties of enameled aluminum wire coils during the embedding process. The instrument simulates actual embedding scenarios, applies pressure to the coil, and measures its deformation and wear state to determine whether it can withstand wear under specified pressure.

[0003] In publicly available literature, patent publication number CN101957288A discloses an enameled wire coil embedding performance tester. This technology uses a mold cavity with a lower opening larger than the diameter of the enameled wire coil to be tested, and a mold cavity with a higher opening smaller than the diameter of the enameled wire coil to be tested. This invention only requires the fabrication of one embedding mold and can use a common tensile testing machine to test the flexibility of the enameled wire, directly reading the deformation force to evaluate the flexibility of the enameled wire. The testing operation is simple and convenient. However, this technology still has the following problems.

[0004] When testing the embedding performance of enameled aluminum wire coils, pressure extrusion is usually used to conduct embedding wear tests. However, during the embedding process, dynamic changes in diameter reduction occur on both the outer and inner sides of the enameled aluminum wire coil. Due to the complexity of this dynamic extrusion, it is difficult to make the outer and inner sides undergo synchronous dynamic changes in diameter reduction in actual testing, and it is also difficult to apply stable pressure to conduct the test. This makes it difficult to accurately reproduce the real situation when simulating the dynamic process of diameter reduction, which greatly reduces the accuracy of the dynamic test simulation of diameter reduction.

[0015] The technical effects and advantages of the present invention.

[0016] 1. This invention sets up an inner diameter reduction component and an outer diameter reduction component in a coordinated manner. When the reduction motor drives the diameter reduction plate to reduce the diameter of one side of the enameled aluminum wire coil, the diameter reduction plate moves backward and simultaneously drives the side groove plate to move backward. Then, through the support column, slide frame and slide bar, the moving rope is pulled, and the moving rope pulls the wave plate to move forward against the spring force. This allows the outer side and the inner side of the enameled aluminum wire coil to change diameter dynamically in sync and apply stable pressure to test the wear state, which greatly improves the simulation accuracy of the diameter reduction dynamic test.

[0017] 2. This invention utilizes a closed-loop control system with a pressure sensor and a controller. When the sleeve block presses against the pressure sensor to reach the set pressure value, the controller automatically controls the reduction motor to reverse, causing the diameter reduction plate to move from the rear to the front. Simultaneously, the spring rebounds and pulls the wave plate back to its original position. This reciprocating motion allows the enameled aluminum wire coil to undergo alternating inner and outer diameter reduction tests under constant pressure. The pressure is more stable during the test, ensuring precise and controllable pressure during the test and improving the reliability of the test data.

[0018] 3. This invention, through the guiding cooperation of the guide post and the sliding block, and the guiding effect of the guide rod on the wave plate, ensures that the reducing plate and the wave plate maintain a parallel and stable moving trajectory during the reducing process. At the same time, the winding post effectively limits the coil, and the inclined slot frame drives the reducing plate to move smoothly through the displacement shaft. The multi-guide structure realizes smooth movement during the reducing process and avoids deviation, ensuring the stability and consistency of the dynamic process of reducing diameter, and further improving the accuracy of the test.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0029] Example 1: like Figure 1 The enameled aluminum wire coil embedding performance tester shown includes a test platform 1, with a frame plate 2 slidably connected to the upper surface of the test platform 1; a pressure applying component installed on the inner wall of the frame plate 2; an inner diameter reduction component disposed on the upper surface of the frame plate 2, with a diameter reduction plate 3 disposed on the inner diameter reduction component; and an outer diameter reduction component disposed at one end of the diameter reduction plate 3, with a wave plate 4 installed on the outer diameter reduction component.

[0030] The operating principle of this embodiment is as follows: First, the enameled aluminum wire coil is wound and attached to the diameter reduction plate 3. The frame plate 2 is moved by the pressure application component, which in turn drives the inner diameter reduction component to move the diameter reduction plate 3 closer to the wave plate 4. At the same time, the inner diameter reduction component drives the diameter reduction plate 3 to perform a dynamic diameter reduction wear test on the inner side of the enameled aluminum wire coil according to a specified pressure. Simultaneously, the diameter reduction plate 3 drives the inner diameter reduction component to move, which in turn drives the wave plate 4 to perform a dynamic diameter reduction wear test on the outer side of the enameled aluminum wire coil according to a specified pressure.

[0031] Example 2: In this embodiment, as Figure 1 - Figure 2 As shown, the pressure-applying component includes: a rotating screw 6 connected to the inner wall of the sleeve plate 2; limit rings 5 ​​rotatably connected to both sides of the sleeve plate 2; and a threaded connection between the rotating screw 6 and the test bench 1. The two limit rings 5 ​​are symmetrically arranged about the sleeve plate 2, and both limit rings 5 ​​are fixedly connected to the rotating screw 6, which is rotatably connected to the sleeve plate 2.

[0032] The operating principle of this embodiment is as follows: by rotating the rotating screw 6, the rotating screw 6 engages with the test platform 1 through a thread, thereby rotating the rotating screw 6 and causing the two limiting rings 5 ​​to rotate. The rotating screw 6 also rotates along the inner wall of the sleeve plate 2. Under the action of the thread engagement force, the rotating screw 6 drives the two limiting rings 5 ​​to push the sleeve plate 2 to the right, and at the same time, the sleeve plate 2 moves to the right along the inner wall of the test platform 1.

[0033] Example 3: In this embodiment, as Figure 1 - Figure 5As shown, the inner diameter reduction component includes: a support frame 7, fixedly connected to the upper surface of the sleeve plate 2, with a geared motor 8 installed on the inner wall of the support frame 7; a drive screw 9, one end of which is installed on the output end of the geared motor 8, the geared motor 8 driving the drive screw 9 to rotate, a sleeve block 10 threadedly connected to the outer wall of the drive screw 9, and the support frame 7 guiding the sleeve block 10 to slide; a pressure sensor 11, installed on one side of the sleeve block 10, the sensing end of the pressure sensor 11 fixedly connected to the sleeve block 10, and a support plate 12 fixed to one end of the pressure sensor 11; and a slanted groove frame 13 located at the pressure sensor. Below 11, the inclined groove frame 13 is fixedly connected to the support plate 12. The inclined groove frame 13 is inclined, and a displacement shaft 14 is slidably connected to the inner wall of the inclined groove frame 13. A moving block 15 is fixed to the bottom end of the displacement shaft 14 and is fixedly connected to the reducing plate 3. A sliding sleeve block 16 is fixed to the other end of the reducing plate 3, and a guide post 17 is installed on the inner wall of the sliding sleeve block 16. The guide post 17 is used to guide the sliding sleeve block 16 to slide and is fixedly connected to the frame plate 2. Two limiting plates 18 are fixedly connected to one side of the reducing plate 3, and two winding posts 19 are fixed between the two limiting plates 18. The inclined groove frame 13 is slidably connected to the moving block 15, and the upper surface of the moving block 15 is at the same horizontal plane as the upper surface of the support plate 12. The two limiting plates 18 are symmetrically arranged about the winding posts 19, and there is a gap between the winding posts 19 and the reducing plate 3.

[0034] The principle of this embodiment is that one end of the enameled aluminum wire coil is wound and tied to the outer wall of a winding post 19 in the early stage, and the other end of the enameled aluminum wire coil is wound and tied to the outer wall of another winding post 19. At the same time, the two winding posts 19 limit the enameled aluminum wire coil, thus completing the winding and installation operation.

[0035] When the sleeve plate 2 moves to the right along the inner wall of the test bench 1, the sleeve plate 2 will drive the guide post 17 to move to the right. The guide post 17 will drive the sliding block 16 to move to the right. The sliding block 16 will cause the reducing plate 3 to move to the right. The reducing plate 3 will start to move closer to the wave plate 4. In this way, the reducing plate 3 will drive the two winding posts 19 to move to the right and move closer to the wave plate 4. The winding posts 19 will drive the enameled aluminum wire coil to move closer to the wave plate 4. In this way, the enameled aluminum wire coil is located at the contact position between the reducing plate 3 and the wave plate 4.

[0036] Simultaneously, controller 30 starts reduction motor 8, which drives drive screw 9 to rotate forward. Drive screw 9 drives sleeve block 10 to move to the left under the action of thread transmission force. Sleeve block 10 drives pressure sensor 11 to move to the left. Pressure sensor 11 drives support plate 12 to move to the left. Support plate 12 drives inclined groove frame 13 to move to the left. Inclined inner wall of inclined groove frame 13 presses displacement shaft 14. Displacement shaft 14 moves backward, driving moving block 15 to move backward. Moving block 15 drives diameter reduction plate 3 to move backward. The sliding sleeve 16 moves backward, guided along the outer wall of the guide post 17, achieving stable backward movement. Simultaneously, the reducing plate 3 moves the limiting plate 18 backward, which in turn moves the winding post 19, causing the enameled aluminum wire coil to move backward and undergo diameter reduction. This reduces the diameter of the extrusion gap between the reducing plate 3 and the undulating plate 4. At the same time, the sleeve block 10 presses against the pressure sensor 11, which senses the pressure. When the pressure value sensed by the pressure sensor 11 is the pressure value set by the controller 30, then... The controller 30 starts the geared motor 8, which drives the drive screw 9 to reverse. This causes the drive screw 9 to move the sleeve block 10 to the right under the force transmitted through the thread. The sleeve block 10 then moves the pressure sensor 11 to the right, which in turn moves the support plate 12 to the right. The support plate 12 then moves the inclined groove frame 13 to the right, which in turn moves the displacement shaft 14 forward. The displacement shaft 14 then moves the moving block 15 forward, which in turn moves the reducing plate 3 forward. This causes the reducing plate 3 to move the sliding sleeve block 16 along the outer wall of the guide post 17. Moving forward, the reducing plate 3 drives the limiting plate 18 to move forward, and the limiting plate 18 drives the winding column 19 to move the enameled aluminum wire coil forward to reduce its diameter and change position. As the reduction motor 8 drives the drive screw 9 to rotate back and forth continuously, the reducing plate 3 can continuously perform diameter reduction and change position wear tests on the enameled aluminum wire coil. At the same time, the enameled aluminum wire coil also moves to the right and makes contact friction between the reducing plate 3 and the wave plate 4. In this way, the reducing plate 3 performs a dynamic change wear test on the inner side of the enameled aluminum wire coil according to the specified pressure.

[0037] Example 4: In this embodiment, as Figure 6 - Figure 8As shown, the outer diameter reduction component includes: a side groove plate 20, fixed to one end of the diameter reduction plate 3, with a support column 21 fixed to the inner wall of the side groove plate 20; a slide frame 22, slidably connected to the outer wall of the support column 21, with limit sleeves 23 slidably connected to both sides of the slide frame 22, and both limit sleeves 23 being fixedly connected to the support column 21; a slide bar 24, fixedly connected to the lower surface of the slide frame 22, with the test platform 1 used to guide the slide bar 24 to slide, and a movable rope 25 fixedly installed at one end of the slide bar 24; and a slide sleeve frame 26, installed on the outer wall of the movable rope 25. The sliding sleeve 26 is fixedly connected to the test platform 1. Both the sliding sleeve 26 and the test platform 1 are slidably connected to the moving rope 25, which is fixedly connected to the wave plate 4. A guide rod 28 is installed on the inner wall of the wave plate 4 and is fixedly connected to the test platform 1. The guide rod 28 guides the wave plate 4 to slide, and the wave plate 4 is slidably connected to the test platform 1. A spring 29 is provided on the outside of the guide rod 28. One end of the spring 29 is fixedly connected to the wave plate 4, and the other end is fixedly connected to the test platform 1. Two guide plates 27 are symmetrically arranged about the wave plate 4, and the cross-sectional shape of the guide plates 27 is arc-shaped.

[0038] The principle of this embodiment is that when the reducing plate 3 moves to the right, the reducing plate 3 drives the side groove plate 20 to move to the right. The side groove plate 20 causes the support column 21 to move to the right. The support column 21 drives the two limiting sleeves 23 to move to the right. The two limiting sleeves 23 move to the right along the sliding frame 22. At the same time, the support column 21 slides to the right along the inner wall of the sliding frame 22. In this way, the sliding frame 22 remains stationary, ensuring that the enameled aluminum wire coil on the reducing plate 3 can be located at the contact position between the reducing plate 3 and the wave plate 4.

[0039] Simultaneously, when the diameter reduction plate 3 moves backward, the diameter reduction plate 3 drives the side groove plate 20 to move backward, the side groove plate 20 drives the support column 21 to move backward, the support column 21 drives the two limit sleeves 23 to move backward, the two limit sleeves 23 cause the slide frame 22 to move backward, the slide frame 22 drives the slide bar 24 to slide backward along the test platform 1, and the slide bar 24 pulls the moving rope 25, the moving rope 25 slides on the inner wall of the slide sleeve frame 26, so the moving rope 25 pulls the wave plate 4 to move forward, the wave plate 4 slides forward along the test platform 1, the wave plate 4 is guided forward along the outer wall of the guide rod 28, and the wave plate 4 pulls the spring 29, the spring 29 provides elastic force to the wave plate 4, and the wave plate 4 drives the two guide plates 27 to move forward and squeeze according to the pressure sensed by the pressure sensor 11, so the diameter change of the gap between the wave plate 4 and the diameter reduction plate 3 is reduced, which can reduce the diameter displacement contact wear of the outer side of the enameled aluminum wire coil by moving forward according to the specified pressure.

[0040] When the reducing plate 3 moves forward, it drives the side groove plate 20 to move forward. The side groove plate 20 causes the support column 21 to move forward. The support column 21 drives the two limit sleeves 23 to move forward. The two limit sleeves 23 cause the slide frame 22 to move forward. The slide frame 22 drives the slide bar 24 to move forward and slide. The slide bar 24 no longer pulls the moving rope 25. Under the action of the spring 29's rebound force, the spring 29 pulls the wave plate 4 to move backward. In this way, the wave plate 4 moves backward along the outer wall of the guide rod 28. In this way, the diameter of the gap between the wave plate 4 and the reducing plate 3 increases. The wave plate 4 performs a dynamic wear test on the outer side of the enameled aluminum wire coil under a specified pressure. After the test is completed, check whether there is any damage to the outer side of the enameled aluminum wire coil. If there is no wear on the paint surface, it is qualified.

[0041] In this embodiment, as Figure 1-3 As shown, a controller 30 is installed on one side of the test bench 1, and the controller 30 is fixedly connected to the test bench 1. The controller 30 starts the geared motor 8 to achieve forward rotation drive of the geared motor 8. When the pressure value sensed by the pressure sensor 11 is the pressure value set by the controller 30, the controller 30 starts the geared motor 8 to drive the drive screw 9 to reverse, thereby achieving precise control of the test pressure.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention.
