[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] See also Figure 1-6 The utility model provides a technical solution: a torque testing device that is easy to replace the fixture, including a workbench 1, a long table 2 is fixedly connected to the top of the workbench 1, a driving mechanism is arranged inside the long table 2, one side of the driving mechanism is connected to a support frame 22, the bottom of the support frame 22 is fixedly connected to two round rods 23, one side of the round rod 23 is connected to a clamping mechanism, one side of the clamping mechanism corresponds to a locking mechanism, the inside of the clamping mechanism corresponds to a fixture 4, a detector 11 is installed on the top of the workbench 1, and the detector 11 corresponds to the fixture 4; first, the operator places the sample to be tested in the fixture 4, and clamps the fixture 4 by the clamping mechanism. The locking mechanism further ensures the stability and safety of the fixture 4. The driving mechanism can drive the support frame 22 to rotate, that is, the entire clamping mechanism rotates. When the fixture 4 needs to be replaced, the driving mechanism drives the support frame 22 to rotate, and the clamping mechanism rotates from the direction of the working state to the state close to the edge of the workbench 1, so that the operator can more conveniently operate to replace the fixture 4. The long table 2 mainly accommodates the driving mechanism. After the fixture 4 is fixed to the specified position, the rear detector 11 cooperates to complete the test. By providing a clamping mechanism, the fixture 4 is firmly clamped during the test process, avoiding damage or accidents to the sample caused by loosening of the fixture during the test. At the same time, the addition of the locking mechanism further enhances the stability and safety of the fixture 4, ensuring the smooth progress of the test process. The driving mechanism improves the convenience and efficiency of replacing the fixture 4.
[0026] The clamping mechanism includes an outer ring 3, which is fixedly connected to the round rod 23, and the inner side of the outer ring 3 is rotatably connected to the inner ring 31. The inner ring 31 is connected to the locking mechanism, and one side of the inner ring 31 is rotatably connected to three clamping blocks 32. One end of the clamping block 32 is movably connected to the inside of the outer ring 3, and the other end of the clamping block 32 corresponds to the clamp 4. First, the outer ring 3 is fixedly connected to the round rod 23, that is, the outer ring 3 is fixed, and the inner ring 31 is rotatably connected to the inner side of the outer ring 3 and will not fall off. The operator rotates the inner ring 31, and one end of the clamping block 32 is connected to the outer ring 3 during rotation, that is, the position of one end of the clamping block 32 is fixed. The connection between the clamp block 32 and the inner ring 31 is equivalent to a fulcrum. When the inner ring 31 rotates, it will move with this fulcrum. When the inner ring 31 rotates counterclockwise, the three clamp blocks 32 will open. When the fulcrum rotates, the end of the clamp block 32 connected to the outer ring 3 will be pushed outward a little. This connection itself is movable. It is stationary in the direction of rotation of the inner ring 31, but there will be some movement in the direction perpendicular to the rotation direction. In this way, the clamp block 32 can be opened and closed. After the internal clamp 4 is clamped, the locking mechanism will limit the rotation of the inner ring 31, making the entire device more stable. By providing a clamping mechanism, the clamp can be quickly clamped and released, the clamp can be firmly clamped, and the stability of the device can be improved.
[0027] The locking mechanism includes a ratchet 33, which is fixedly connected to the inner ring 31. The bottom of the support frame 22 is fixedly connected to an L-shaped block 24, and a pawl 25 is rotatably connected to one side of the L-shaped block 24. The ratchet 33 and the pawl 25 correspond to each other. When the inner ring 31 rotates clockwise, that is, when the clamp 4 is to be clamped, the ratchet 33 also rotates clockwise. The cooperation between the ratchet 33 and the pawl 25 limits the ratchet 33 to only clockwise rotation. After the clamp 4 is clamped, the ratchet 33 can no longer rotate in the clockwise direction. Under the restriction of the pawl 25, it will not rotate counterclockwise either, so the whole is very stable. When the clamp 4 needs to be replaced, the operator can simply open the pawl 25. By providing a locking mechanism, the clamp 4 is further clamped to ensure that the overall stability is high.
[0028] A circular groove is provided in the middle of the ratchet 33 ; the circular groove facilitates the passage of the clamp 4 without affecting the clamping.
[0029] After the three clamping blocks 32 are tightened, their central portions form a triangular shape. The connection between the three clamping blocks 32 and the inner ring 31 is located in the middle of the clamping blocks 32. The central portion of the clamping blocks 32 after tightening is triangular, and this triangular shape coincides with the triangular block 41 at the top of the clamp 4, thus better securing the clamp 4 and ensuring stability. The connection between the three clamping blocks 32 and the inner ring 31 is located in the middle of the clamping blocks 32, so that the connection has sufficient space to move.
[0030] The middle part of the top cylindrical rod of the clamp 4 is a triangular block 41, which corresponds to the clamping block 32 after being clamped; the middle part of the three clamping blocks 32 after clamping is triangular, and this triangular shape just matches the triangular block 41 at the top of the clamp 4, so that the clamp 4 can be better fixed and stability can be ensured.
[0031] A push block 34 is fixedly connected to one side of the inner ring 31 ; the push block 34 extends out of the outside of the clamping mechanism, making it convenient for an operator to rotate the inner ring 31 .
[0032] The drive mechanism includes a motor located inside the long table 2. The output end of the motor is fixedly connected to a rotating shaft 21. The rotating shaft 21 and the support frame 22 are also fixedly connected. When the operator needs to open the drive mechanism, they turn on the motor, and the rotating shaft 21 at the output end rotates, which in turn rotates the support frame 22, thereby rotating the entire mechanism, facilitating the replacement of the clamp 4. The rotating shaft 21 and the long table 2 are rotatably connected, so that the rotation of the rotating shaft 21 is not restricted.
[0033] Working principle: The operator first places the sample to be tested in the fixture 4. The top of the fixture 4 is designed with a triangular block 41, which is used to cooperate with the clamping block 32 in the clamping mechanism to ensure a firm clamp. The operator rotates the inner ring 31 by pushing the block 34. By rotating the inner ring 31 clockwise, the three clamping blocks 32 approach each other and gradually clamp the fixture 4. When the inner ring 31 rotates clockwise, the ratchet 33 also rotates clockwise. The pawl 25 cooperates with the ratchet 33 to limit the ratchet 33 to only rotate clockwise, ensuring that the fixture 4 will not loosen during the test. After the fixture 4 is clamped and stabilized, the drive mechanism drives the support frame 22 to rotate, bringing the fixture 4 to the top of the detector 11, and the operator starts the detector 11 for testing. When the fixture 4 needs to be replaced, the driving mechanism drives the support frame 22 to rotate, and rotates the clamping mechanism to a position close to the edge of the workbench 1. The operator pushes open the pawl 25, releases the restriction on the ratchet 33, rotates the inner ring 31 in the opposite direction, and the clamp 32 opens. The operator replaces the fixture 4. After replacing the fixture 4, the above clamping operation and testing phase are repeated to carry out the next round of testing.
