Description

Technical Field

[0001] This utility model relates to the technical field of torque testing machines, specifically a four-station automatic adjustable torque testing machine. Background Technology

[0002] In the production of roll-type products, torque is one of the key indicators for measuring their quality; substandard torque directly affects the product's performance and lifespan. Currently, the testing and adjustment of roll torque are mostly carried out manually or using single-station equipment.

[0003] Manual operation requires workers to manually clamp the rolls and use simple tools to test and adjust torque. This is not only labor-intensive and inefficient, but also highly susceptible to human error, making it difficult to guarantee consistent and accurate results, and thus failing to meet the demands of mass production. Furthermore, while single-station equipment reduces manual intervention to some extent, it can only process one roll at a time. When faced with large-scale roll testing and adjustment tasks, its efficiency remains low, and it mostly only performs single torque value tests, lacking flexibility and making it difficult to optimize product quality by comparing product performance under different torque conditions. Therefore, it cannot adequately meet the requirements of modern production for efficient, accurate, and flexible testing. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1-7 As shown, this utility model provides a four-station automatic torque adjustment testing machine, mainly used for testing the torque of roll products. During testing, it is mainly performed by the torque testing mechanism 2 and the torque adjustment mechanism 3. The torque testing mechanism 2 is used to detect the torque, while the torque adjustment mechanism 3 is used to adjust the torque of the roll. It should be noted that the roll generally includes an adjusting element for adjusting the tightness, which is then controlled and adjusted to a certain torque value by the torque adjustment mechanism 3.

[0039] The structure of the torque tester includes a frame 1, on which four test stations are provided. Each test station is equipped with a torque testing mechanism 2 and a torque adjustment mechanism 3 that work together. By setting up multiple stations, multiple rollers can be tested and adjusted simultaneously, which greatly improves work efficiency.

[0040] The torque testing mechanism 2 includes an X-axis moving module 21 fixed on the frame body 1. The X-axis moving module 21 can control the slide 22 to move along the X-axis direction. The two ends of the slide 22 are respectively fixed with a testing component 23 and a gripper component 24.

[0041] The test component 23 is one of the core components for realizing torque testing. It includes a geared motor 231, a torque sensor 232, and a fixture 233, which are arranged coaxially on the slide table 22. The fixture 233 is used to fix one end of the reel. When the geared motor 231 works, it will drive the reel to rotate. The torque sensor 232 can detect the torque magnitude when the reel rotates in real time.

[0042] The gripper assembly 24 is used to hold the other end of the reel to ensure the stability of the reel during testing. It includes a third moving module 241 fixed on the slide table 22. The third moving module 241 can control the second moving module 242 to move along the Y-axis, and the second moving module 242 can control the gripper 243 to move along the X-axis. Through the adjustment of movement in these two directions, the gripper 243 can accurately hold the other end of the reel.

[0043] Specifically, the third moving module 241 includes a sixth guide rail 2411 mounted on the slide table 22, and a sliding frame 2412 that moves on the sixth guide rail 2411 and is connected to the second moving module 242. The sliding frame 2412 can be manually pushed to slide and adjust to a specified position on the sixth guide rail 2411, thereby driving the second moving module 242 to move along the Y-axis. The second moving module 242 includes a clamping movable plate 2421 that moves along the X-axis on the sliding frame 2412 and is connected to the gripper 243, and a clamping adjustment cylinder 2422 that drives the clamping movable plate 2412 to move. The clamping adjustment cylinder 2422 can control the clamping movable plate 2421 to move in the X-axis direction so that the gripper 243 can complete the clamping operation.

[0044] The torque adjustment mechanism 3 is located above the torque testing mechanism 2. It includes a torque adjustment motor 31 and a fourth moving module 32. The fourth moving module 32 can drive and control the torque adjustment motor 31 to move along the Z-axis. When it is necessary to adjust the torque of the roll, the fourth moving module 32 moves the torque adjustment motor 31 to a suitable position, and the torque adjustment motor 31 can adjust the torque of the roll by working.

[0045] The frame 1 is equipped with a gantry frame 11 fixed at both ends. The fourth moving module 32 is slidably connected to the first guide rail 12 mounted on the gantry frame 11. This structural design allows the fourth moving module 32 to move stably. The fourth moving module 32 includes a first sliding plate 321 that moves on the first guide rail 12, a second guide rail 322 mounted on the first sliding plate 321, a torque adjusting lifting plate 323 that moves on the second guide rail 322 and is connected to a torque motor, and a lifting cylinder 324 that drives the torque adjusting lifting plate 323 to move. When the lifting cylinder 324 is working, it pushes the torque adjusting lifting plate 323 to move on the second guide rail 322, thereby driving the torque adjusting motor 31 to move along the Z-axis.

[0046] In addition to the fourth moving module 32, the gantry frame 11 is also connected to a material chuck 4 for taking out the roll, a fifth moving module 5 for driving and controlling the movement of the material chuck 4, and a transmission assembly 6 for driving and controlling the movement of the fifth moving module 5. The fifth moving module 5 is slidably connected by the fourth guide rail 13 mounted on the gantry frame 11.

[0047] Specifically, the fifth moving module 5 includes a picking base plate 51 that moves on the fourth guide rail 13, a fifth guide rail 52 mounted on the picking base plate 51, a picking lifting plate 53 that moves on the fifth guide rail 52 and is connected to the picking chuck 4, and a picking cylinder 54 that drives the picking lifting plate 53 to move. The picking cylinder 54 can drive the picking lifting plate 53 to move on the fifth guide rail 52, thereby driving the picking chuck 4 to move along the Z-axis direction, while the transmission component 6 can drive... The moving material-retrieving base plate 51 moves on the fourth guide rail 13, realizing the movement of the material-retrieving chuck 4 along the X-axis. The transmission assembly 6 includes guide wheels 61 located at both ends of the gantry frame 11, a transmission belt 62 sleeved on the outside of the two guide wheels 61 for transmission, and a transmission motor 63 that drives one of the guide wheels 61 to rotate. When the transmission motor 63 is working, it will drive the guide wheel 61 to rotate, thereby causing the transmission belt 62 to move. The transmission belt 62 is fixed to the material-retrieving base plate 51, thereby driving the material-retrieving base plate 51 to move.

[0048] To facilitate the storage and retrieval of the reels, return boxes 7 are provided on opposite sides of the frame body 1 for placing the reels that have completed testing and adjustment. A release box 8 is also provided on one side of the frame body 1 for storing reels to be tested. Furthermore, a semi-enclosed cover 9 is installed on the outside of the frame body 1 to protect the equipment and operators. Directional casters 10 are provided at the bottom of the frame body 1 to facilitate the movement and position adjustment of the equipment.

[0049] When this four-station automatic torque adjustment testing machine is in operation, firstly, the roll to be tested is taken out from the feeding box 8 and placed in the testing station, with one end of the roll fixed on the fixture 233. The fourth moving module 32 drives the torque adjustment motor 31 to move to a suitable position along the Z-axis. The torque adjustment motor 31 adjusts the torque of the roll, and after adjustment, the torque adjustment motor 31 rises to reset. The X-axis moving module 21 drives the slide table 22 to move, and the other end of the roll is clamped by the gripper 243 of the gripper assembly 24. At this time, the reduction motor 231 drives the roll to rotate, and the torque sensor 232 detects the torque of the roll. If the torque value needs to be adjusted, the gripper assembly 24 resets through the X-axis moving module 21, and the torque adjustment motor 31 descends to adjust the torque value again. After the torque value adjustment is completed, the torque adjustment motor 31 rises to reset, and the gripper assembly 24 clamps again for torque testing. During the test, the torque sensor 232 monitors in real time during the adjustment process until the torque meets the requirements.

[0050] After testing and adjustment are completed, the gripper assembly 24 releases the material from the roll, and the X-axis moving module 21 moves the slide table 22, causing the fixture 233 to move along the X-axis to below the material pick-up chuck 4. Driven by the fifth moving module 5 and the transmission assembly 6, the material pick-up chuck 4 moves to the corresponding position, clamps the roll, removes it from the testing station, and places it into the return box 7. After that, the equipment can proceed with the testing and adjustment of the next batch of rolls.

[0051] Compared with traditional technologies, the torque testing machine provided by this technical solution can test multiple rolls simultaneously by setting up four testing stations, which greatly improves the efficiency of testing and meets the needs of batch testing. During testing, the torque can be adjusted to different torque values ​​through the torque adjustment mechanism 3, which improves the flexibility of testing. When used in conjunction with multiple testing stations, a clear test comparison can be formed, which helps to improve and enhance the quality of products.

[0052] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this invention, and no reference numerals in the claims should be construed as limiting the scope of the claims.
