Description

Technical Field

[0001] This invention relates to the field of enameled wire, and more specifically, to an enameled wire tensile testing device. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked.

[0003] In order to check the pass rate of products during the production process, enameled wire generally undergoes various tests, such as tensile testing using a tensile testing machine. Conventional tensile testing devices test a single enameled wire at a time, and then compare the tensile test results of different batches of enameled wire. However, there are many samples in the production process of enameled wire, so the types of samples tested at one time are often diverse. When testing under the same environment, it is necessary to set the parameters of the tensile testing machine each time, which greatly increases the workload of the inspectors.

[0004] There are currently no effective solutions to the problems in the relevant technologies. Summary of the Invention

[0038] The invention will now be further described with reference to the accompanying drawings and specific embodiments:

[0039] Example 1: Please refer to Figure 1-4This embodiment discloses a tensile testing device for enameled wire, including a base plate 1. Support plates 2 are symmetrically mounted on the top of the base plate 1 along its center. A fixing plate 7 is fixedly mounted between the support plates 2. A servo motor 8 is mounted on the top of the fixing plate 7. A horizontally arranged rotating frame 3 is mounted on the output shaft end of the servo motor 8. A tensile mechanism 4 is fixedly mounted on the top of the rotating frame 3. Several parallel clamping components 5 are mounted on the tensile mechanism 4. A top plate 6 is also provided between the tensile mechanism 4 and the clamping components 5. The clamping components 5 can clamp the enameled wire, while the tensile mechanism 4 can adjust the position of the clamping components 5. When the clamping components 5 are separated, the enameled wire can be stretched to observe the breakage of the enameled wire during the stretching process, thereby determining the qualification status of different batches of enameled wire produced.

[0040] A reinforcing rib 10 is fixedly installed between the bottom of the fixed plate 7 and the side wall of the support plate 2. The reinforcing rib 10 can enhance the installation strength of the fixed plate 7 and ensure the stability of the servo motor 8 and the rotating frame 3.

[0041] The rotating frame 3 includes a horizontally arranged horizontal plate 11. The bottom of the horizontal plate 11 has a mounting groove 111. A rotating seat 9 is fixedly installed inside the mounting groove 111. The rotating seat 9 is installed at the output shaft end of the servo motor 8. End frames 12 are fixedly installed at both ends of the horizontal plate 11. A horizontal frame 13 is fixedly installed at the top of the end frames 12. Extension frames 14 are integrally provided symmetrically along the center on both sides of the horizontal frame 13. A first cylinder 15 and a second cylinder 16 are respectively installed at the bottom of the extension frames 14 on both sides. The output shaft end of the first cylinder 15 is connected to the tensioning mechanism 4 to adjust the tensioning mechanism 4. The output shaft end of the second cylinder 16 is connected to the top plate 6 to adjust the clamping assembly 5.

[0042] Please see Figure 5-9 The tensioning mechanism 4 includes two opposing upright blocks 17, which are fixedly installed at the top ends of the crossbar 13. A crossbar 18 is fixedly installed between the upright blocks 17. Several moving components 19 are slidably installed on the crossbar 18. The number of clamping components 5 is equal to the number of moving components 19 and corresponds one-to-one. The clamping components 5 are fixedly installed on the moving components 19. An adjusting plate 20 is provided on the side of the crossbar 18 away from the clamping components 5. A slide block 21 is fixedly installed on the side wall end of the adjusting plate 20 facing the upright block 17. A slide rail 22 is fixedly installed on the outer wall of the upright block 17. The slide block 21 is slidably installed on the slide rail 22. Several adjusting holes 23 are symmetrically opened along the center of the adjusting plate 20. The number of adjusting holes 23 is equal to the number of moving components 19. The end of the moving component 19 facing the adjusting plate 20 is slidably disposed in the corresponding adjusting hole 23. The adjusting holes 23 are radiating on the adjusting plate 20.

[0043] Applying a force to the adjusting plate 20 causes it to move up and down along the slide rail 22 via the slide block 21. As the adjusting plate 20 moves, it adjusts the moving component 19 through the adjusting hole 23. The moving component 19 is slidably mounted on the crossbar 18, so the distance between the moving components 19 can be adjusted equidistantly through the adjusting hole 23, thereby adjusting the distance between the clamping components 5. When the clamping components 5 stably clamp the enameled wire, the equidistant change in the distance between them allows for a tensile test.

[0044] An assembly frame 24 is fixedly installed at the bottom center of the adjusting plate 20, and the end of the assembly frame 24 away from the adjusting plate 20 is fixedly installed at the output shaft end of the first cylinder 15. When the first cylinder 15 is started, the adjusting plate 20 can be moved up and down by the assembly frame 24.

[0045] The movable component 19 includes a movable block 25 with a mounting hole 26. A sliding sleeve 27 is installed through the mounting hole 26 and slidably sleeved on the outside of the crossbar 18. A fixing frame 28 is fixedly installed at the middle of one end of the movable block 25 facing the adjusting plate 20. A guide wheel 29 is rotatably installed at the middle of the fixing frame 28 and is located in the adjusting hole 23. When the adjusting plate 20 moves up and down, it drives the guide wheel 29 to move within the adjusting hole 23. The guide wheel 29 then drives the movable block 25 to move through the fixing frame 28. The movable block 25 then slides and adjusts along the length of the crossbar 18 via the sliding sleeve 27.

[0046] A fixing block 30 is fixedly installed on the top side of the movable block 25 away from the adjusting plate 20. The fixing block 30 has an assembly hole 31 inside, and the bottom of the clamping assembly 5 is fixedly installed in the assembly hole 31. The clamping assembly 5 is fixedly installed through the assembly hole 31 in the fixing block 30.

[0047] A guide rod 32 is fixedly installed at the top end of the stand block 17. A strip-shaped opening 36 is provided in the middle of the top plate 6 along its length, facing the fixing block 30. The bottom of the clamping assembly 5 passes through the strip-shaped opening 36. A guide sleeve 33 is also installed through the top plate 6, and the top end of the guide rod 32 passes through the guide sleeve 33. A support column 34 is fixedly installed at the center of one side of the bottom of the top plate 6. A mounting bracket 35 is fixedly installed at the bottom end of the support column 34, and the mounting bracket 35 is fixedly connected to the output shaft end of the second cylinder 16. When the second cylinder 16 is started, the second cylinder 16 can drive the support column 34 to rise and fall through the mounting bracket 35. The support column 34 can then drive the top plate 6 to rise and fall. The guide sleeve 33 can slide along the guide rod 32, thereby ensuring the stability of the top plate 6 during the rise and fall adjustment.

[0048] Through the above-described solution of the present invention, the present invention can adjust multiple sets of clamping components 5 at equal intervals by means of the tensioning mechanism 4. After the enameled wire is stably clamped by the clamping components 5, the enameled wire can be subjected to equal-interval tension test by means of the adjustment of the tensioning mechanism 4. The servo motor 8 can also drive the rotating frame 3 to adjust the angle through the rotating seat 9, thereby realizing the position adjustment of the tensioning mechanism 4 and the clamping components 5, which makes it more convenient for the staff to operate.

[0049] Example 2: Please refer to Figure 10-13 In Embodiment 2, to ensure stable clamping of the enameled wire by the clamping assembly 5, the clamping assembly 5 includes a support arm 37, which is fixedly inserted into the mounting hole 31. A strip plate 38 is fixedly installed at the top end of the support arm 37, perpendicular to the crossbar 18. A mounting opening 39 is symmetrically formed at the top of the strip plate 38 along its center, extending along its length. An adjusting seat 40 is slidably installed within the mounting opening 39, and a gripper 41 is fixedly installed at the top of the adjusting seat 40. The gripper 41 is used to stably clamp and fix the enameled wire, while the adjusting seat 40 can move the gripper 41 on the strip plate 38. This allows the grippers 41 on adjacent strip plates 38 to remain collinear and adjusts the distance between grippers 41 on the same strip plate 38, ensuring mutual influence during subsequent tensile testing.

[0050] The bottom center of the strip plate 38 is provided with a slot 42, and a retaining edge 43 is integrally provided on the top outer wall of the support arm 37. The top of the support arm 37 is inserted into the slot 42, and the top of the retaining edge 43 is tightly abutting the opening of the slot 42.

[0051] The inner wall of the slot 42 is provided with a sliding groove 44 that runs along its length. The outer wall of the adjusting seat 40 is integrally provided with a slider 48, which slides within the sliding groove 44. The outer wall of the strip plate 38 is provided with a strip hole 45 that runs along its length and connects to the sliding groove 44. A stud 49 is fixedly installed on the outer wall of the slider 48, with the end of the stud 49 passing through the strip hole 45. A nut 50 is also screwed onto the outside of the stud 49. The horizontal movement of the adjusting seat 40 can be adjusted by the cooperation of the slider 48 and the sliding groove 44. Tightening the nut 50 and pressing it against the outer wall of the strip plate 38 can position the adjusting seat 40.

[0052] The top surface of the strip plate 38 is also provided with a scale line 46, which is arranged along the outer side of the assembly port 39. The middle part of the adjusting seat 40 has a through-hole 47, and the bottom of the gripper 41 passes through the through-hole 47 and is set tightly against the top of the top plate 6. A pointer 51 is also fixedly installed in the middle of the outer wall of the slider 48. The position of the adjusting seat 40 can be positioned by using the pointer 51 and the scale line 46, which facilitates the accurate collinear positioning and adjustment of the two grippers 41 arranged opposite each other on the two adjacent strip plates 38.

[0053] Please see Figure 14-17 The gripper 41 includes a fixed base 52, which is fixedly mounted on the adjusting base 40. A vertical plate 53 is integrally provided on the top of the fixed base 52. Right-angle arms 54 are swayably installed on both sides of the vertical plate 53 near the edge. A horizontally arranged guide rail 55 is installed on the top of both sides of the vertical plate 53. A guide seat 56 is slidably installed on the guide rail 55. An assembly plate 57 is fixedly installed on the guide seat 56. A first notch 58 is opened at the bottom of the assembly plate 57. A hinge frame 59 is integrally provided on the top of the right-angle arm 54. A first hinge shaft 60 is installed on the hinge frame 59 and is located in the first notch 58. A connecting seat 61 is also fixedly installed on the top of the assembly plate 57. A gripper 62 is integrally provided on the top of the connecting seat 61.

[0054] When the right-angle arm 54 begins to swing under external force, the top of the right-angle arm 54 will drive the first hinge shaft 60 to move through the hinge frame 59. The first hinge shaft 60 will then push or pull the assembly plate 57 to move through the first notch 58. The assembly plate 57 will move stably along the guide rail 55 through the guide seat 56. At the same time, the assembly plate 57 will also drive the clamping handle 62 to move through the connecting seat 61. When the assembly plates 57 on both sides of the vertical plate 53 move relative to each other, they can drive the corresponding clamping handles 62 to move towards each other, eventually making contact and clamping the enameled wire.

[0055] The bottom center of the fixed base 52 has a through hole 63, and a push rod 64 is inserted into the through hole 63. The bottom center of the vertical plate 53 has a notch 531, and the top of the through hole 63 is connected to the notch 531. The top of the push rod 64 passes through the through hole 63 and is located in the notch 531. A second hinge shaft 65 is installed at the top end of the push rod 64. The bottom of the right-angle arm 54 has a second notch 66, and the two ends of the second hinge shaft 65 are respectively located in the corresponding second notches 66. The bottom end of the push rod 64 is tightly abutted against the top of the top plate 6. When the top plate 6 rises, it pushes the push rod 64 to move. The movement of the push rod 64 pushes the second notch 66 through the second hinge shaft 65, thereby causing the right-angle arm 54 to swing, thus adjusting the clamp 62.

[0056] A retaining ring 67 is fixedly installed on the bottom of the top rod 64. A retaining seat 69 is fixedly installed on the bottom of the fixing base 52, located outside the through hole 63. A clamping spring 68 is provided between the retaining seat 69 and the retaining ring 67, and the clamping spring 68 is sleeved on the outside of the top rod 64. The clamping spring 68 can provide a pushing force to the retaining ring 67 through the retaining seat 69. This pushing force will eventually act on the top rod 64, thereby enabling the top rod 64 to automatically descend. This allows the two clamping handles 62 to automatically move closer to each other, achieving automatic clamping of the enameled wire. When the top plate 6 pushes the top rod 64, the top rod 64 will compress the clamping spring 68 through the retaining ring 67. At this time, the top rod 64 will eventually separate and adjust the clamping handles 62. When the top plate 6 descends, the clamping spring 68 will return to its original position, thereby enabling the clamping handles 62 to move closer to each other again.

[0057] Through the above-described solution of the present invention, the clamping claw 41 provided by the present invention can automatically clamp the enameled wire through the tightening spring 68, and the position of the clamping claw 41 on the strip plate 38 can be adjusted, thereby ensuring that the clamping claws 41 on two adjacent strip plates 38 can always be collinearly arranged. At the same time, the distance between two adjacent clamping claws 41 on the same strip plate 38 can be adjusted to avoid mutual interference when stretching the enameled wire, and it is also convenient to install the enameled wire on the clamping claw 41. The opening and closing of the clamping handle 62 provided on the clamping claw 41 can be quickly adjusted by raising and lowering the top plate 6, which is simple and convenient.

[0058] To facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process will be described in detail below.

[0059] The present invention can adjust the multiple clamping components 5 at equal intervals by setting the tensioning mechanism 4. After the enameled wire is stably clamped by the clamping components 5, the enameled wire can be subjected to equal-interval tension test by adjusting the tensioning mechanism 4. The servo motor 8 can also drive the rotating frame 3 through the rotating seat 9 to adjust the angle, thereby realizing the position adjustment of the tensioning mechanism 4 and the clamping components 5, which makes it more convenient for the staff to operate.

[0060] The clamping jaws 41 of this invention can automatically clamp the enameled wire through the tightening spring 68, and the position of the clamping jaws 41 on the strip plate 38 can be adjusted, thereby ensuring that the clamping jaws 41 on two adjacent strip plates 38 can always be collinear. At the same time, the distance between two adjacent clamping jaws 41 on the same strip plate 38 can be adjusted to avoid mutual interference when stretching the enameled wire, and it is also convenient to install the enameled wire on the clamping jaws 41. The opening and closing of the clamping handle 62 on the clamping jaws 41 can be quickly adjusted by raising and lowering the top plate 6, which is simple and convenient.
