[0001] This utility model relates to the field of high and low voltage switch testing technology, and in particular to an automatic testing device for high and low voltage switches before they leave the factory. Background Technology

[0002] High and low voltage switches are switches used to control high and low voltage systems. They are widely used in power systems, electronic equipment, industrial production and other fields. Their main function is to switch or shut down circuits within the rated voltage range. The high and low voltage switch manufacturing industry is an important part of the power transmission and transformation equipment manufacturing industry and occupies a very important position in the entire power industry.

[0003] Traditional high and low voltage switch factory testing devices can usually only test high and low voltage switches individually, which makes the factory testing of high and low voltage switches slow. Furthermore, due to the low stability of the test, the reliability of the factory testing of high and low voltage switches is reduced. Therefore, it is necessary to design an automatic factory testing device for high and low voltage switches. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an automatic testing device for high and low voltage switches at the factory.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an automatic testing device for high and low voltage switches, comprising a testing platform and a second motor. The testing platform is equipped with a first motor, and a gear is fixedly connected to the output end of the first motor. A transmission shaft is meshed with one side of the gear via teeth. A sliding plate is fixedly connected to the first transmission shaft, and a second sliding plate is slidably connected to the first transmission shaft. A fixed block is slidably connected to the first transmission shaft. The other side of the gear is meshed with a second transmission shaft via teeth. A sliding plate is slidably connected to the second transmission shaft, and a second sliding plate is fixedly connected to the second transmission shaft. A fixed clamping plate is fixedly connected to the second sliding plate, and a fixed block is slidably connected to the second transmission shaft.

[0006] As a further description of the above technical solution: The output end of the second motor is fixedly connected to a first connecting rod, the first connecting rod is hinged to a second connecting rod, the second connecting rod is hinged to a sector plate, the sector plate is rotatably connected to a fixed shaft, the sector plate is slidably connected to an arc-shaped rack via a slider, the arc-shaped rack meshes with a second gear, the second gear is fixedly connected to a rotating sleeve, the rotating sleeve is rotatably connected to a fixed column, and the rotating sleeve is fixedly connected to a rotating shaft.

[0007] As a further description of the above technical solution: The test platform is equipped with a second motor, a support leg is fixedly connected to the test platform, a fixed shaft is fixedly connected to the test platform, a fixed plate is fixedly connected to the test platform, and a fixed column is fixedly connected to the fixed plate.

[0008] As a further description of the above technical solution: The fixed plate is slidably connected to a pull shaft, the pull shaft is fixedly connected to a second fixed clamping plate, the fixed plate is slidably connected to a rotating shaft, and the rotating shaft is fixedly connected to a third fixed clamping plate.

[0009] As a further description of the above technical solution: The second fixed clamp and the rotating shaft are fixedly connected by an internal spring. There are three fixed plates, and four sets of the second and third fixed clamps.

[0010] As a further description of the above technical solution: The first sliding plate and the second sliding plate are provided in four sets.

[0011] As a further description of the above technical solution: The test platform is fixedly connected to a fixed cover plate, and the test platform is fixedly connected to a fixed block, with two fixed blocks symmetrically arranged.

[0012] This utility model has the following beneficial effects: 1. In this utility model, motor 2 drives connecting rod 1 to rotate, thereby connecting rod 1 drives the sector plate to rotate in a semi-circle around the fixed shaft via connecting rod 2. Then, the arc-shaped rack on the sector plate drives gear 2 to rotate. Gear 2 drives the rotating shaft to slide in the groove on the fixed plate via the rotating sleeve. The rotating shaft is clamped by fixed clamping plate 2 and fixed clamping plate 3, so that the switching action of the levers on the high and low voltage switches can be effectively tested during the factory test of the high and low voltage switches. This helps to discover and solve problems in the high and low voltage switches at the time of leaving the factory, and improves the reliability of the high and low voltage switches.

[0013] 2. In this utility model, the first motor drives the first gear to rotate, and the first gear drives the first and second transmission shafts to slide in different directions. This causes the first and second transmission shafts to drive the first fixed clamping plate on the first and second sliding plates to approach and clamp the high and low voltage switches. This increases the stability of the high and low voltage switches during factory testing. Since the first and second sliding plates are provided with four sets, the high and low voltage switch factory testing device can test multiple switches at once, thus improving the speed of the high and low voltage switch factory testing device.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-4This utility model provides an embodiment of an automatic testing device for high and low voltage switches, comprising a testing platform 1 and a second motor 4. The testing platform 1 is equipped with a first motor 3. A gear 8 is fixedly connected to the output end of the first motor 3. A transmission shaft 9 is meshed with one side of the gear 8 via teeth. A sliding plate 11 is fixedly connected to the transmission shaft 9, and a second sliding plate 12 is slidably connected to the transmission shaft 9. A fixing block 13 is slidably connected to the transmission shaft 9. A second transmission shaft 10 is meshed with the other side of the gear 8 via teeth. A sliding plate 11 is slidably connected to the transmission shaft 10, and a second sliding plate 12 is fixedly connected to the transmission shaft 10. A fixing clamp 7 is fixedly connected to the sliding plate 12. The transmission shaft 10 slides... A fixed block 13 is connected, and a motor 4 drives a connecting rod 15 to rotate. This causes the connecting rod 15 to drive a sector plate 17 to rotate in a semi-circle around a fixed shaft 18 via a connecting rod 16. The sector plate 17 then drives a gear 20 to rotate via an arc-shaped rack 19. The gear 20 drives a rotating shaft 22 to slide in a groove on a fixed plate 5 via a rotating sleeve 21. The rotating shaft 22 is clamped by a fixed clamping plate 24 and a fixed clamping plate 25, which allows for effective testing of the switching action of the high and low voltage switches during factory testing. This helps to identify and resolve problems that exist in the high and low voltage switches at the time of factory testing, thereby improving the reliability of the high and low voltage switches.

[0018] The output end of motor 24 is fixedly connected to connecting rod 15. Connecting rod 15 is hinged to connecting rod 26. Connecting rod 26 is hinged to sector plate 17. Sector plate 17 is rotatably connected to fixed shaft 18. Sector plate 17 is slidably connected to arc rack 19 via slider. Arc rack 19 meshes with gear 20. Gear 20 is fixedly connected to rotating sleeve 21. Rotating sleeve 21 is rotatably connected to fixed column 26. Rotating sleeve 21 is fixedly connected to rotating shaft 22. Motor 24 is mounted on test platform 1. Test platform 1 is fixedly connected to support leg 2. Test platform 1 is fixedly connected to fixed shaft 18. Test platform 1 is fixedly connected to fixed plate 5. Fixed plate 5 is fixedly connected to fixed column 26. Fixed plate 5 is slidably connected to pull... The moving shaft 23 is fixedly connected to the second fixed clamping plate 24. The fixed plate 5 is slidably connected to the rotating shaft 22. The rotating shaft 22 is fixedly connected to the third fixed clamping plate 25. The second fixed clamping plate 24 and the rotating shaft 22 are fixedly connected by an internal spring. There are three fixed plates 5, four sets of the second fixed clamping plates 24 and the third fixed clamping plate 25, and four sets of the first sliding plate 11 and the second sliding plate 12. The test platform 1 is fixedly connected to the fixed cover plate 6 and the test platform 1 is fixedly connected to the fixed block 13. There are two fixed blocks 13 symmetrically arranged. Because there are four sets of the first sliding plate 11 and the second sliding plate 12, the high and low voltage switch factory test device can test multiple switches at once, which improves the speed of the high and low voltage switch factory test device.

[0019] Working Principle: Before the high and low voltage switches leave the factory, they need to be tested to determine their functionality. First, during testing, motor 3 is started. Motor 3 rotates, driving gear 8 to rotate. Gear 8 drives transmission shafts 9 and 10 to slide in opposite directions. Transmission shaft 9 drives sliding plate 11 to slide, and transmission shaft 10 drives sliding plate 12 to slide, bringing sliding plates 11 and 12 closer together. This causes the fixing clamp 7 to clamp the high and low voltage switches for testing. Then, pulling shaft 23 causes the fixing clamp 24 to open. A spring inside rotating shaft 22 allows the levers on the high and low voltage switches to move freely. After inserting the second fixed clamp 24 and the third fixed clamp 25, release the pulling shaft 23, which will cause the second fixed clamp 24 and the third fixed clamp 25 to clamp the levers on the high and low voltage switches. Then, start the second motor 4, which drives the first connecting rod 15 to rotate. The first connecting rod 15 drives the sector plate 17 to rotate in a semi-circle around the fixed shaft 18 through the second connecting rod 16. This causes the sector plate 17 to drive the second gear 20 to rotate in a semi-circle through the arc rack 19. The second gear 20 drives the rotating shaft 22 to rotate back and forth along the slide groove on the fixed plate 5 through the rotating sleeve 21. Finally, the rotating shaft 22 drives the levers on the high and low voltage switches fixed on the second fixed clamp 24 and the third fixed clamp 25 to test the switching action.
