The clamping structure includes a rotating column 14 that rotates through the middle of the U-shaped frame 13. A sensor is installed at one end of the rotating column 14. The sensor is a tension sensor and a torque sensor. A fixed frame 15 is installed on the sensor. An electric telescopic rod 16 is installed on the inner wall of the fixed frame 15 near the U-shaped frame 13. A first through groove 17 is opened on the other side of the fixed frame 15. A fixed plate 22 is connected to the other side of the fixed frame 15 below the first through groove 17. A second clamp 23 is installed at one end of the fixed plate 22. A rotating shaft is rotatably connected between the front and rear walls of the first through groove 17. A flip plate 20 is fixedly sleeved on the rotating shaft. A first clamp 21 is installed at one end of the flip plate 20. A first gear 19 is fixedly sleeved in the middle of the rotating shaft. One end of the output shaft of the electric telescopic rod 16 is connected to a drive bar 18. The drive bar 18 is provided with teeth that mesh with the first gear 19. The first clamp 21 has a concave arc-shaped groove 25 in the middle of its lower part, and the second clamp 23 has a protrusion 24 in the middle of its upper part. The protrusion 24 has an arched shape on its side. Rubber pads 26 are provided on both sides of the upper part of the second clamp 23. The transmission structure includes a rotating cylinder 27 that rotates through a movable plate 4. A second groove 58 is formed in the middle of the movable plate 4. A turntable 30 is fixedly fitted on the rotating cylinder 27 at the second groove 58. A third gear 31 is fixedly fitted on the turntable 30 and meshes with a second gear 29. The second gear 29 is fixedly fitted on a rotating column 14 and is located in a second through groove 28 on a U-shaped frame 13. A crossbar 56 moves through the rotating cylinder 27. Vertical plates 36 are fixedly fitted at both ends of the crossbar 56. The bottom ends of the vertical plates 36 are fixedly connected to the base 1. A first groove 33 is formed on the right side of the crossbar 56 along its length. A first spiral groove 34 communicating with the first groove 33 is formed near the middle of the crossbar 56. A groove 34 is formed on the left side of the crossbar 56.

Insert rods 32 are fixedly inserted into both rotating cylinders 27. The bottom end of one insert rod 32 on the right is movably inserted into the first groove 33, and the bottom end of one insert rod 32 on the left is movably inserted into the second spiral groove 35. First, the insulating paper to be tested is placed between the two sets of first clamps 21 and second clamps 23. Then, the electric telescopic rod 16 in the fixed frame 15 is activated, driving the drive bar 18 to move. Through the first gear 19, the flip plate 20 and the first clamp 21 rotate downwards as a whole, thereby clamping and fixing the insulation between the first clamp 21 and the second clamp 23. Furthermore, the setting of the convex strip 24 and the concave arc groove 25 increases the clamping area of ​​the insulating paper. The rubber pad... The setting 26 increases static friction with the insulation, making the clamping of the insulation paper more secure. Then, the first motor 5 is started to drive the screw 6 to rotate. The first motor 5 is a forward and reverse motor. When the screw 6 rotates, the right moving block 3 drives the corresponding moving plate 4 to move on the base 1. The left moving block 3 is limited by the limit block 57, so that the left moving plate 4 is kept in place. When the right moving plate 4 moves, it drives the sleeve 7 to move on the fixed rod 8, stretching the spring 9. With the help of the sensor, the tensile strength of the insulation paper is detected. After the detection, the first motor 5 drives the screw 6 to rotate in the opposite direction, and the right moving plate 4 moves in the opposite direction to reset. As the screw 6 continues to move, the sleeve 7 pushes the ring 10 against the fixed ring 11. The push simultaneously moves the left-side movable plate 4 on the base 1 to the left, and the two movable plates 4 drive the rod 32 on the rotating cylinder 27 to slide in the first spiral groove 34 and the second spiral groove 35 of the crossbar 56 respectively. Since the spiral directions of the first spiral groove 34 and the second spiral groove 35 are opposite, and in conjunction with the second gear 29 and the third gear 31, the two rotating columns 14 are driven to rotate synchronously in opposite directions, thereby driving the two sets of first clamps 21 and second clamps 23 to rotate in opposite directions, realizing the work of testing the bending strength of the insulating paper. In this way, the structure of the testing device is simpler and the manufacturing cost is lower. Moreover, the tensile strength and bending strength of the insulating paper can be tested during the back and forth movement of the insulating paper, and the testing efficiency is higher.

[0017] See Figures 3-7 The collection structure includes a bottom groove 38 on the left side of the front of the base 1. Slide grooves 40 are provided on both sides of the bottom groove 38. A collection frame 42 is movably inserted into the bottom groove 38. Slide bars 39 are provided on both sides of the collection frame 42 and inserted into the slide grooves 40. A handle 41 is provided on the front of the collection frame 42. The gripping structure includes two support plates 37 connected to the left side of the base 1. A rotating rod 44 passes between the two support plates 37. Two sleeve frames 45 are fixedly fitted on the rotating rod 44. An insert plate 46 is movably inserted into the two sleeve frames 45. A fixed clamping plate 47 is set at the top of the insert plate 46. The top of the insert plate 46 rotates through a clamping rod 59. A flipping clamping plate 48 is fixedly fitted on the clamping rod 59. A driving structure is set between the clamping rod 59 and the support plates 37. A second motor 43 is installed at the top of the right side of the right support plate 37. One end of the output shaft of the second motor 43 is connected to the clamping rod 59. The driving structure includes a through-hole block 49 connected to the bottom end of the sleeve frame 45. A through-hole groove is formed on the side of the sleeve frame 45 along its length. The through-hole block 49 moves through the through-hole. A driving rod 50 is connected to the through-hole block 49. A first arc-shaped groove 51 is formed at the top of one side of the support plate 37. A second arc-shaped groove 52 is formed on the support plate 37, connecting to the first arc-shaped groove 51. One end of the driving rod 50 is movably inserted into the first arc-shaped groove 51. A fixing strip 53 connects the top ends of the two sleeve frames 45, and a middle strip is connected to the middle of the fixing strip 53. 54. A fourth gear 55 is fixedly sleeved on the middle of the clamping rod 59. The middle strip 54 is provided with teeth that mesh with the fourth gear 55. After the bending strength of the insulating paper is detected during the movement of the moving plate 4, the screw 6 stops rotating and the second motor 43 on the support plate 37 is started. The second motor 43 is a forward and reverse motor. The second motor 43 drives the rotating rod 44 to rotate, thereby driving the sleeve frame 45 and the insert plate 46 to rotate downward as a whole, and also driving one end of the driving rod 50 on the through block 49 to slide in the first arc groove 51. When one end of the driving rod 50 slides from the first arc-shaped groove 51 into the second arc-shaped groove 52, it pushes the insert plate 46 to move away from the sleeve frame 45, thereby moving the fixed clamping plate 47 and the flipping clamping plate 48 to the upper and lower sides of the bent insulating paper. During the movement, the insert plate 46 drives the fourth gear 55 to roll on the middle strip 54, thereby automatically driving the flipping clamping plate 48 to rotate towards the fixed clamping plate 47, clamping the tested insulating paper between the fixed clamping plate 47 and the flipping clamping plate 48. At this time, the insulating paper is released between the two sets of first clamps 21 and second clamps 23. Then the second motor 43 continues to drive the rotating rod 44 to rotate. When the flipping clamp 48 and the fixed clamp 47 move the insulating paper to the top of the collection frame 42, one end of the driving rod 50 slides from the second arc groove 52 to the first arc groove 51. The insulating paper is automatically released between the flipping clamp 48 and the fixed clamp 47, and the insulation is automatically discharged into the collection frame 42, thereby further improving the efficiency of the detection work.

[0018] The implementation principle of the insulation paper strength performance testing device according to an embodiment of the present invention is as follows: First, the insulation paper to be tested is placed between two sets of first clamps 21 and second clamps 23. Then, the electric telescopic rod 16 in the fixed frame 15 is activated, driving the driving bar 18 to move. Through the first gear 19, the flip plate 20 and the first clamps 21 rotate downward as a whole, thereby clamping and fixing the insulation between the first clamps 21 and the second clamps 23. The setting of the convex bar 24 and the concave arc groove 25 increases the clamping area of ​​the insulation paper, and the setting of the rubber pad 26 increases the static friction between the rubber pad and the insulation, making the clamping of the insulation paper more secure. Then, the first motor 5 is activated to drive the screw 6 to rotate. The first motor 5 is a forward and reverse motor. When the screw 6 rotates, the right side... The moving block 3 drives the corresponding moving plate 4 to move on the base 1. The left moving block 3 is limited by the limiting block 57, so that the left moving plate 4 remains stationary. When the right moving plate 4 moves, it drives the sleeve 7 to move on the fixed rod 8, stretching the spring 9. In conjunction with the sensor, the tensile strength of the insulating paper is tested. After the test, the first motor 5 drives the screw 6 to rotate in the opposite direction, and the right moving plate 4 moves in the opposite direction to reset. As the screw 6 continues to move, the push ring 10 at one end of the sleeve 7 pushes the fixed ring 11, thereby simultaneously driving the left moving plate 4 to move to the left on the base 1. The two moving plates 4 drive the insert rod 32 on the rotating cylinder 27 to slide in the first spiral groove 34 and the second spiral groove 35 of the crossbar 56, respectively. The first spiral groove 34 and the second spiral groove 35 have opposite spiral directions and, in conjunction with the second gear 29 and the third gear 31, drive the two rotating columns 14 to rotate synchronously in opposite directions. This, in turn, drives the two sets of first clamps 21 and second clamps 23 to rotate in opposite directions, thus enabling the detection of the bending strength of the insulating paper. This makes the detection device simpler in structure and lower in manufacturing cost. Furthermore, it can detect the tensile and bending strength of the insulating paper during its back-and-forth movement, resulting in higher detection efficiency. After the bending strength of the insulating paper is detected during the movement of the moving plate 4, the screw 6 stops rotating, and the second motor 43 on the support plate 37 is started. The second motor 43 is a forward and reverse motor, which drives the rotating rod 44 to rotate, thereby driving the sleeve frame 45 and the insert... The plate 46 rotates downwards as a whole, causing one end of the driving rod 50 on the through block 49 to slide in the first arc groove 51. When one end of the driving rod 50 slides from the first arc groove 51 to the second arc groove 52, it pushes the insert plate 46 to move away from the sleeve frame 45, thereby causing the fixed clamping plate 47 and the flipping clamping plate 48 to move to the upper and lower sides of the bent insulating paper. During the movement, the insert plate 46 drives the fourth gear 55 to roll on the middle strip 54, thereby automatically driving the flipping clamping plate 48 to rotate towards the fixed clamping plate 47, clamping the tested insulating paper between the fixed clamping plate 47 and the flipping clamping plate 48. At this time, the insulating paper is released between the two sets of first clamps 21 and second clamps 23, and then the second motor 43 continues to drive the rotating rod 44 to rotate.When the flipping clamp 48 and the fixed clamp 47 move the insulating paper above the collection frame 42, one end of the driving rod 50 slides from the second arc-shaped groove 52 into the first arc-shaped groove 51, automatically releasing the insulating paper between the flipping clamp 48 and the fixed clamp 47. The paper is then automatically discharged into the collection frame 42, thus enabling the detection of the insulating paper.

Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
