Technical Field

[0001] This application relates to the field of offset adjustment fixture technology, and in particular to an offset adjustment fixture for a torque testing machine. Background Technology

[0002] With the rapid development of the manufacturing industry, the requirements for product quality and performance are becoming increasingly stringent. Among many industrial products, such as automotive parts, aerospace components, and mechanical transmission parts, the accurate assessment of their torsional performance is crucial. Torque testing machines, as key equipment for testing the torsional performance of materials and parts, directly affect the accuracy of product quality judgment through their measurement accuracy. However, in actual use, torsion testing machines often experience displacement and deviation due to various factors, affecting the test results. Therefore, developing a fixture that can effectively adjust the deviation has become an urgent need for the industry.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A misalignment adjustment fixture for a torque testing machine includes: a torque testing machine body, wherein a hydraulic cylinder is disposed on the right side inside the torque testing machine body. The X-direction miniature guide rail is slidably installed on the top side inside the body of the torque testing machine. The right side of the X-direction miniature guide rail is fixedly connected to the output shaft of the hydraulic cylinder. Hydraulic cylinder two is located inside the rear side of the torque testing machine body; The Y-direction miniature guide rail is slidably installed on the bottom side inside the torsion testing machine body. The rear side of the Y-direction miniature guide rail is fixedly connected to the output shaft of the second hydraulic cylinder. The Y-direction miniature guide rail is located below the X-direction miniature guide rail. The sensing mechanism, located inside the torsion testing machine body, is used to sense the micro guide rails in the X and Y directions. The buffer mechanism, located inside the torsion testing machine body, is used to buffer the micro guide rails in the X and Y directions. The locking mechanism, located inside the torsion testing machine body, is used to lock the micro guide rails in the X and Y directions.

[0006] Preferably, the sensing mechanism includes a connecting plate 1 disposed at one end of the X-direction miniature guide rail and the Y-direction miniature guide rail, a temperature sensor is disposed at one end of each of the two connecting plates 1, and an alarm is disposed at one end of each of the two connecting plates 1.

[0007] Preferably, the buffer mechanism includes two connecting plates fixedly installed at the other ends of the X-direction miniature guide rail and the Y-direction miniature guide rail, with springs fixedly installed at the other ends of the two connecting plates, dampers fixedly installed at the other ends of the two springs, and buffer plates fixedly installed at the other ends of the two dampers.

[0008] Preferably, the other ends of the X-direction micro guide rail and the Y-direction micro guide rail are fixedly installed with telescopic plates, the other ends of the two telescopic plates are fixedly connected to one end of the buffer plate, the other ends of the two buffer plates are fixedly installed with rubber buffer pads, and a buffer is provided at the center of the top and bottom sides inside the torsion testing machine body.

[0009] Preferably, the locking mechanism includes locking boxes fixedly installed inside the top and bottom sides of the torque testing machine body. The interior of each of the two locking boxes is provided with a groove, and the interior of each of the two grooves is provided with a hydraulic cylinder. The output shafts of the two hydraulic cylinders are fixedly installed with locking blocks, and the exteriors of the two locking blocks are slidably connected to the two grooves.

[0010] Preferably, each of the two locking blocks has a locking block at one end, each locking block has an installation groove inside, each installation groove has a spring plate fixedly installed inside, and each spring plate has an inclined block fixedly installed on its right side.

[0011] Preferably, one end of the X-direction micro guide rail and the Y-direction micro guide rail is provided with a slot, the interior of the X-direction micro guide rail and the Y-direction micro guide rail is provided with a sliding groove, a drive motor is provided inside each of the two sliding grooves, the output shafts of the two drive motors are fixedly mounted with screws, the outer surfaces of the two screws are rotatably connected to the sliding grooves, and the outer surfaces of the two screws are threaded with connecting blocks.

[0012] Preferably, the exterior of both connecting blocks is slidably connected to the slot and the sliding groove, and a push plate is fixedly installed at one end of each of the two connecting blocks, with the exterior of the two push plates slidably connected to the slot.

[0013] The beneficial effects of the offset adjustment fixture for the torque testing machine described in this utility model are as follows: Because of the sensing mechanism, the temperature sensor can detect the temperature of the micro guide rails in the X and Y directions, and automatically adjust the position or related parameters of the guide rails according to the temperature changes, so as to ensure that the fixture can work normally in different temperature environments. When a fault or abnormal situation occurs, the alarm can detect the guide rail fault information, issue an alarm signal in time, and display the fault information, so as to facilitate the operator to quickly locate and solve the problem and reduce equipment downtime. Because of the buffer mechanism, the buffer plate will eventually contact the inner wall of the torsion testing machine body. At this time, the buffer plate will be subjected to the reaction force of the inner wall, which will compress the spring. During the compression of the spring, the telescopic plate will adjust its extension and retraction according to the compression of the spring. Together with the buffer plate and the rubber buffer pad on it, they will absorb and disperse the impact force brought by the movement of the guide rail. At the same time, the buffer will also play a role in this buffering process, which will assist the overall buffering effect, further reduce the speed and impact force of the guide rail movement, thereby improving the stability of the fixture during the buffering process. Because of the locking mechanism, the spring plate inside the locking block will cooperate with the inclined block as the locking block moves. The elasticity of the spring plate allows the inclined block to be tightly locked into the slot, thereby locking the guide rail and ensuring that the guide rail remains in a fixed position during the test. When the push plate contacts the inclined block, it will apply a pushing force to the inclined block and push the inclined block out of the slot. During this process, the movement of the inclined block will compress the spring plate. Because it is designed to precisely correct the position of the fixture in the X and Y directions, it corrects displacement deviations and restores the fixture to its normal working position.

[0014] This invention can adjust the guide rail when the fixture is misaligned, and also buffer the guide rail, thus improving the performance. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Example 1

[0018] Reference Figures 1-7 A misalignment adjustment fixture for a torque testing machine, comprising: The main body 1 of the force testing machine and the right side of the torsion testing machine body 1 are equipped with a hydraulic cylinder 4. The X-direction miniature guide rail 5 is slidably installed on the top side inside the body 1 of the torque testing machine. The right side of the X-direction miniature guide rail 5 is fixedly connected to the output shaft of the hydraulic cylinder 4. Hydraulic cylinder 2 is located inside the rear side of the torsion testing machine body 1; The Y-direction miniature guide rail 3 is slidably installed on the bottom side inside the body 1 of the torque testing machine. The rear side of the Y-direction miniature guide rail 3 is fixedly connected to the output shaft of the hydraulic cylinder 2. The Y-direction miniature guide rail 3 is located below the X-direction miniature guide rail 5. The sensing mechanism is located inside the body 1 of the torque testing machine and is used to sense the micro guide rail 5 in the X direction and the micro guide rail 3 in the Y direction. A buffer mechanism is installed inside the torsion testing machine body 1 to buffer the X-direction micro guide rail 5 and the Y-direction micro guide rail 3; The locking mechanism is located inside the torsion testing machine body 1 and is used to lock the X-direction micro guide rail 5 and the Y-direction micro guide rail 3.

[0019] In this embodiment, the sensing mechanism includes a connecting plate 1 disposed at one end of the micro guide rail 5 in the X direction and the micro guide rail 3 in the Y direction. A temperature sensor 6 is disposed at one end of each of the two connecting plates 1, and an alarm 22 is disposed at one end of each of the two connecting plates 1.

[0020] In this embodiment, the buffer mechanism includes two connecting plates fixedly installed at the other ends of the X-direction miniature guide rail 5 and the Y-direction miniature guide rail 3. Springs 7 are fixedly installed at the other ends of both connecting plates, and dampers are fixedly installed at the other ends of both springs 7. Buffer plates 9 are fixedly installed at the other ends of both dampers. Springs 7 have good elastic deformation capabilities, storing energy when subjected to pressure and releasing energy after the pressure is released. When the buffer plate compresses the spring, spring 7 absorbs a large amount of kinetic energy from the movement of the guide rails, converting it into elastic potential energy. The telescopic plate 8, in conjunction with the extension and retraction of spring 7, can better adapt to the deformation of spring 7, ensuring that spring 7 maintains a stable working state during compression and extension, thereby more effectively absorbing impact energy.

[0021] In this embodiment, telescopic plates 8 are fixedly installed at the other ends of the X-direction miniature guide rail 5 and the Y-direction miniature guide rail 3. The other ends of the two telescopic plates 8 are fixedly connected to one end of the buffer plate 9. The other ends of the two buffer plates 9 are fixedly installed with rubber buffer pads. The rubber buffer pads are soft and elastic. They can further fill the gap between the buffer plate 9 and the inner wall of the testing machine body, increase the contact area of ​​the buffer, disperse the impact force, and reduce the damage to the equipment and fixtures caused by excessive local pressure. A buffer is set at the center of the top and bottom sides inside the torsion testing machine body 1. The buffer can provide additional damping force during the buffering process, slow down the movement speed of the guide rail, and make the whole buffering process more stable. This can not only reduce the vibration caused by the rapid movement of the guide rail, but also reduce the noise caused by the vibration, providing a relatively quiet and stable environment for the test. In some occasions with high requirements for the test environment, such as laboratories or precision manufacturing workshops, reducing noise and vibration can improve the accuracy and efficiency of the test.

[0022] In this embodiment, the locking mechanism includes locking boxes 10 fixedly installed inside the top and bottom sides of the torque testing machine body 1. Both locking boxes 10 have grooves 21 inside, and both grooves 21 have hydraulic cylinders 11 inside. Both hydraulic cylinders 11 have locking blocks 12 fixedly installed on their output shafts. The exterior of both locking blocks 12 is slidably connected to the two grooves 21.

[0023] In this embodiment, each of the two locking blocks 12 has a locking block 13 at one end, and each of the two locking blocks 13 has an installation groove inside. Each of the two installation grooves has a spring plate 14 fixedly installed inside, and each of the two spring plates 14 has a wedge block 15 fixedly installed on the right side.

[0024] In this embodiment, one end of the X-direction micro guide rail 5 and the Y-direction micro guide rail 3 is provided with a slot 16, and the interior of the X-direction micro guide rail 5 and the Y-direction micro guide rail 3 is provided with a sliding groove. The interior of each sliding groove is provided with a drive motor 17, and the output shafts of each drive motor 17 are fixedly mounted with a screw 18. The outer surfaces of each screw 18 are rotatably connected to the sliding groove, and the outer surfaces of each screw 18 are threadedly connected with a connecting block 19.

[0025] In this embodiment, the exterior of both connecting blocks 19 is slidably connected to the slot 16 and the sliding groove, and a push plate 20 is fixedly installed at one end of each of the two connecting blocks 19. The exterior of the two push plates 20 is slidably connected to the slot 16.

[0026] In this invention, when the fixture is misaligned, hydraulic cylinder 4 is activated, its output shaft pushes the X-direction miniature guide rail 5 forward, and simultaneously hydraulic cylinder 2 is activated, its output shaft pushes the Y-direction miniature guide rail 3 forward. This allows for precise correction of the fixture's position in the X and Y directions, thereby correcting the misalignment and restoring the fixture to its normal working position. When buffering is required for the Y-direction miniature guide rail 3 and X-direction miniature guide rail 5, during the forward movement of the guide rails, the Y-direction miniature guide rail 3 and X-direction miniature guide rail 5 will simultaneously drive the connecting plate 2, spring 7, telescopic plate 8, damper, and buffer plate 9 to move forward together. The buffer plate 9 will eventually contact the inner surface of the torque testing machine body 1. When the buffer plate 9 is subjected to the reaction force of the inner wall, it will compress the spring 7. During the compression of the spring 7, the telescopic plate 8 will adjust its extension and retraction according to the compression of the spring 7. Together with the buffer plate 9 and the rubber buffer pad on it, they will absorb and disperse the impact force brought by the movement of the guide rail. At the same time, the buffer will also play a role in this buffering process, playing an auxiliary role in the overall buffering effect, further reducing the speed and impact force of the guide rail movement, thereby improving the stability of the fixture during the buffering process. When it is necessary to lock the Y-direction miniature guide rail 3 and the X-direction miniature guide rail 5, the hydraulic cylinder 11 is activated, and its output shaft pushes the locking block 12 forward. The locking block 12 slides inside the groove 21, and with the locking... When the fixed block 12 moves, the spring plate 14 inside the locking block 13 will cooperate with the inclined block 15. The elasticity of the spring plate 14 allows the inclined block 15 to be tightly locked into the slot 16, thereby achieving a locking and clamping of the guide rail. This ensures that the guide rail remains in a fixed position during the test. When it is necessary to release the Y-direction miniature guide rail 3 and the X-direction miniature guide rail 5, the drive motor 17 is started. Its output shaft drives the screw 18 to rotate. During the rotation of the screw 18, the connecting block 19 and the push plate 20 will move forward. When the push plate 20 contacts the inclined block 15, it will apply a pushing force to the inclined block 15, pushing the inclined block 15 out of the slot 16. During this process, the movement of the inclined block 15 will compress the spring plate 14. The hydraulic cylinder 11 is restarted, causing its output shaft to push the locking block 12 backward. The locking block 12 returns along the original path, finally unlocking the guide rail and allowing it to be readjusted. When it is necessary to sense the Y-direction miniature guide rail 3 and the X-direction miniature guide rail 5, the temperature sensor 6 can detect the temperature of the X-direction miniature guide rail 5 and the Y-direction miniature guide rail 3, and automatically adjust the position or related parameters of the guide rail according to the temperature change, ensuring that the fixture can work normally in different temperature environments. When a fault or abnormal situation occurs, the alarm 22 can detect the guide rail fault information, issue an alarm signal in time, and display the fault information, making it convenient for operators to quickly locate and solve problems and reduce equipment downtime. Example 2

[0027] The difference between this embodiment and Embodiment 1 is that: a push rod motor 1 is installed at the top and bottom of the torsion testing machine body 1, and a push rod motor 2 is installed on the output shaft of each of the two push rod motor 1s. A cleaning brush is fixedly installed on the output shaft of each of the two push rod motor 2s. This brush can clean the surfaces of the Y-direction miniature guide rail 3 and the X-direction miniature guide rail 5, preventing impurities or particles from remaining on the guide rail surface, which would affect the sliding effect and accuracy of the guide rail. At the same time, the cleaning brush can also effectively reduce the friction between the guide rail and the fixture, extending the service life of the guide rail. The cleaning brush is made of wear-resistant and soft material, which can effectively remove stains and impurities on the guide rail without damaging the guide rail surface.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
