Description

Technical Field

[0001] This utility model relates to the field of diamond wire torsion testing technology, and more specifically, it relates to a diamond wire torsion testing fixture. Background Technology

[0002] Multi-wire cutting machines utilize diamond wire to achieve high-speed cutting, doubling the cutting feed speed. They also employ water-based cutting fluid with a small amount of water, making them recyclable, environmentally friendly, and energy-efficient, significantly reducing cutting costs and achieving truly efficient and environmentally friendly production. However, diamond wire exhibits twisting during its movement. Insufficient torsional strength can easily lead to wire breakage and significant waste. Therefore, controlling the torsional strength of diamond wire and selecting high-quality testing equipment and fixtures for testing and evaluation is crucial.

[0003] A search revealed that Chinese utility model patent application number CN201921836813.9 discloses a diamond wire torsion test fixture, which includes a fixture body. One end of the fixture body is connected to a torsion tester as a connecting end, and the other end is provided with a clamping cavity as a clamping end. A clamping block is provided in the clamping cavity. A clamping groove for placing diamond wire is provided on the bottom surface of the clamping block along its length direction. The radial height of the clamping cavity is greater than the thickness of the clamping block. The fixture body is provided with a lifting rod for lifting the clamping block in the clamping cavity and a locking member for locking the clamping block in the clamping cavity.

[0004] When in use, operating the lifting rod can raise the clamping block a certain distance, creating a gap between the bottom surface of the clamping block and the bottom surface of the clamping cavity. At this time, there needs to be a gap between the ends of the two fastening bolts and the clamping block. The diamond wire passes through the gap and enters the clamping groove. Then, the lifting rod is lowered, and the clamping block falls down to press the diamond wire. Then, the two fastening bolts are operated to make the ends of the fastening bolts press against the clamping block, thereby pressing the diamond wire tightly through the clamping block.

[0005] The torsion tester will cause the clamp and diamond wire to twist during the test. Since the clamping groove has a certain width, which is much larger than the diameter of the diamond wire, it is not convenient to insert the diamond wire into the middle position inside the clamping groove. As a result, the clamped diamond wire is not located on the central axis of the torsion tester, which leads to a deviation in the diamond wire torsion test results and reduces the accuracy of the diamond wire torsion test.

[0018] Compared with the prior art, this utility model provides a diamond wire torsion test fixture, which has the following beneficial effects:

[0019] 1. Insert the diamond wire into the circular slot. By rotating the first bidirectional screw, the rotation of the first bidirectional screw moves the two adjusting plates towards the center. The two adjusting plates drive the two lower positioning seats and the two upper positioning seats to move towards the center respectively.

[0031] Please see Figures 1-5A diamond wire torsion test fixture includes a fixture body 1, on which two sets of clamping mechanisms are arranged vertically. A circular through groove 2 is provided at the middle position of the side end of the fixture body 1, and the two clamping mechanisms are located at the middle position of the circular through groove 2. A first through groove 3 is provided on both sides of the two clamping mechanisms on the fixture body 1. A lower positioning seat 4 is slidably arranged inside the lower side of the first through groove 3, and a sliding plate 5 is slidably arranged inside the upper side of the first through groove 3. An upper positioning seat 6 is fixedly connected to the bottom end of the sliding plate 5. The upper positioning seat 6 and the lower positioning seat 4 are connected to each other. Each base 4 has a triangular groove 7 at its bottom. A first bidirectional screw 8 is rotatably connected to the clamp body 1. Both ends of the first bidirectional screw 8 are fixedly connected to a third throttle 21 to facilitate rotation of the first bidirectional screw 8. The first bidirectional screw 8 has two adjusting plates 9 symmetrically threaded on its exterior. The two adjusting plates 9 are fixedly connected to two lower positioning seats 4 and two sliding plates 5 respectively. A slot 10 that matches the upper positioning seat 6 is provided at the middle of the top of the lower positioning seat 4, which facilitates the positioning of diamond wires of different diameters by the upper positioning seat 6 and the lower positioning seat 4.

[0032] Specifically, the diamond wire is inserted into the circular slot 2. By rotating the first bidirectional screw 8, the two adjusting plates 9 move towards the center. The two adjusting plates 9 respectively drive the two lower positioning seats 4 and the two upper positioning seats 6 to move towards the center. Through the cooperation of the upper positioning seats 6 and the lower positioning seats 4, the diamond wire is positioned in the middle position inside the circular slot 2. This facilitates the two clamping mechanisms to clamp and fix the diamond wire in the middle position, ensuring that the clamped diamond wire is located on the central axis of the torsion testing machine. This avoids deviations in the diamond wire torsion test results and ensures the accuracy of the diamond wire torsion test.

[0033] Please see Figure 1 and Figure 3 The clamping mechanism includes a second bidirectional screw 11. A second through groove 12 is provided on the clamping body 1. A sliding groove 13 is provided on the side end of the second through groove 12. The second bidirectional screw 11 is located inside the sliding groove 13 and is rotatably connected to the clamping body 1. Two sliding blocks 14 are symmetrically threaded onto the outside of the second bidirectional screw 11. Both sliding blocks 14 are slidably engaged with the sliding groove 13. A clamping plate 15 is fixedly connected to the side end of each of the two sliding blocks 14. The clamping plate 15 is slidably engaged with the second through groove 12. A non-slip pad 16 is fixedly connected to the side end to increase the friction of the clamping plate 15 surface. A first handle 17 is rotatably connected to the clamping body 1. The first handle 17 is fixedly connected to the side end of the second bidirectional screw 11 to facilitate the rotation of the second bidirectional screw 11. Two fixing blocks 18 are fixedly connected to the side of the second through groove 12 away from the slide groove 13. Both fixing blocks 18 are threaded with a pressing screw 19. A second handle 20 is fixedly connected to the side end of the pressing screw 19 to ensure the stability of the diamond wire clamping and fixing.

[0034] Specifically, by rotating the second bidirectional screw 11 counterclockwise, the two slide blocks 14 move towards the center, which in turn moves the two clamping plates 15 towards the center. The two clamping plates 15 clamp and fix the diamond wire in the middle position. The two clamping mechanisms facilitate clamping the diamond wire in the vertical and horizontal directions as well as the front and back directions, thereby clamping the diamond wire in multiple directions and improving the stability of clamping and fixing the diamond wire. Then, by rotating the compression screw 19 clockwise, the screw moves towards the side closer to the clamping plate 15, which facilitates compression of the clamping plate 15 and improves the stability of clamping the diamond wire by the clamping plate 15.

[0035] Please see Figure 1 , Figure 4 and Figure 5 The clamp body 1 has a connecting groove 22 on its side end, and a connecting block 23 is inserted into the connecting groove 22. The clamp body 1 is threaded with a fixing screw 24 that mates with the connecting block 23. A connecting piece 25 is fixedly connected to the side end of the connecting block 23, which facilitates the replacement of the connecting piece 25.

[0036] Specifically, the connector 25 is inserted into the interior of the connecting groove 22 via the connecting block 23, and then the connecting block 23 is fixed by tightening the fixing screw 24. Loosening the fixing screw 24 makes it easy to pull the connecting block 23 out of the interior of the connecting groove 22, which facilitates the replacement of the connector 25. It also facilitates the replacement of different models of connector 25 and makes it easy to install them on different models of torque testing machines.

[0037] In summary, when using the overall equipment:

[0038] The diamond wire is installed on the corresponding torsion testing machine via the connector 25. At this time, the central axis of the circular slot 2 is located on the central axis of the torsion testing machine. Then, the diamond wire is inserted into the interior of the circular slot 2. Then, the first bidirectional screw 8 is rotated counterclockwise. The rotation of the first bidirectional screw 8 causes the two adjusting plates 9 to move towards the center. The two adjusting plates 9 respectively drive the two lower positioning seats 4 and the two upper positioning seats 6 to move towards the center. Through the cooperation of the upper positioning seats 6 and the lower positioning seats 4, the diamond wire is positioned in the middle position inside the circular slot 2, so that the diamond wire located on both sides of the two clamping mechanisms is located in the middle position of the circular slot 2. Then, the second bidirectional screw 11 is rotated counterclockwise. The rotation of the second bidirectional screw 11 causes the two slide seats 14 to move towards the center. The two slide seats 14 drive the two clamping plates 15 to move towards the center. The two clamping plates 15 clamp and fix the diamond wire in the middle position. Then, the pressing screw 19 is rotated clockwise. The screw moves towards the side closer to the clamping plate 15 and presses the side of the clamping plate 15 away from the slide seat 14, thereby stably clamping and fixing the diamond wire.
