They are mainly used in scientific research institutes, commodity inspection and arbitration institutions, building materials and other industries. They are indispensable testing equipment for material development, physical testing, teaching and research, quality control, incoming material inspection and random inspection of production lines. In the production process of steel shafts, it is necessary to conduct push-pull force tests on the finished steel shafts to check whether the finished steel shafts are qualified.
[0003] However, existing steel shaft push-pull force testing devices have limited applicability because the clamping size of the fixture is not adjustable, meaning the fixture can only clamp steel shafts of a fixed diameter. Furthermore, when the test material breaks, there is a possibility of fragments flying, posing a significant safety hazard to the operator.
[0004] To address this problem, this application provides a push-pull force testing device for steel shaft machining. Utility Model Content

[0022] The present invention will be further described in detail below with reference to embodiments:
[0023] like Figure 1-4 As shown, this utility model provides a push-pull force testing device for steel shaft processing, including a connecting component 1, a clamping component 2, and a moving component 3. The connecting component 1 includes a housing 10 and a support leg 11. The support leg 11 is fixedly connected to the inside of the housing 10. A cabinet door 12 is rotatably installed on the front of the housing 10. An observation window 13 is provided on the front of the cabinet door 12. A controller 14 is fixedly installed on one side of the housing 10. A fixing plate 15 is fixedly installed inside the housing 10.
[0024] like Figure 2-4 As shown, the clamping assembly 2 is located inside the connecting assembly 1. The clamping assembly 2 includes a hydraulic cylinder 20 and a clamping block 24. The clamping block 24 is fixedly installed at one end of the hydraulic cylinder 20, which is fixedly installed on the top of the fixing plate 15. A protective telescopic tube 23 is fixedly installed at the bottom of the fixing plate 15, and a guide rail 21 is fixedly installed on the top of the fixing plate 15. The clamping block 24 is slidably installed inside the guide rail 21. An installation hole 22 is provided inside the fixing plate 15. The protective telescopic tube 23 is opened, the steel shaft to be tested is placed into the installation hole 22, and the hydraulic cylinder 20 is started by the controller 14, so that the hydraulic rod pushes the clamping block 24 to move along the guide rail 21 to clamp the steel shaft to be tested. By pushing the clamping block 24 through the hydraulic cylinder 20, the clamping block 24 can clamp steel shafts of different diameters. Through the combined action of the installation hole 22, the hydraulic cylinder 20, the guide rail 21, and the clamping block 24, the applicability of the device is expanded.
[0025] like Figure 2-4As shown, the moving component 3 is located inside the connecting component 1. The moving component 3 includes a motor 30, which is fixedly installed inside the housing 10. A moving plate 35 is slidably installed inside the second guide rail 36, and a third guide rail 38 is slidably installed inside the moving plate 35. One end of the third guide rail 38 is fixedly installed at the bottom of the housing 10, and the bottom of the protective telescopic tube 23 is fixedly installed at the top of the moving plate 35. A fixed seat 37 is fixedly installed at the other end of the third guide rail 38. The second guide rail 36 is fixedly installed inside the housing 10. A threaded rod 34 is threadedly installed inside the moving plate 35. By setting two threaded rods 34 inside the moving plate 35, the movement of the moving plate 35 is more balanced, preventing errors in experimental data. The threaded rod 34 is rotatably installed inside the housing 10, and the bottom end of the threaded rod 34 is fixedly installed inside the housing 10. The device is equipped with a worm gear 32, which is externally meshed with a worm 33. A reducer 31 is fixedly installed at the other end of the worm 33. One end of the motor 30 is fixedly installed inside the reducer 31. After the steel shaft is clamped, the motor 30 is started by the controller 14, which drives the worms 33 on both sides to rotate through the reducer 31. The worms 33 then drive the worm gear 32 and the threaded rod 34 to rotate, causing the moving plate 35 to move along the guide rail 38 and the guide rail 26. The push-pull force test is performed on the steel shaft. Because the protective telescopic tube 23 is telescopic, it can always protect the steel shaft when the moving plate 35 moves. Through the combined action of the fixed plate 15, the moving plate 35, and the protective telescopic tube 23, the device prevents fragments from flying when the steel shaft breaks, thus improving the safety of the equipment.
[0026] The working principle of the push-pull force testing device for steel shaft machining will be explained in detail below.
[0027] like Figure 1-4As shown, when using the push-pull force testing device for steel shaft machining, first open the cabinet door 12 using the handle, then open the protective telescopic tube 23, place the steel shaft to be tested into the mounting hole 22, and start the hydraulic cylinder 20 through the controller 14, causing the hydraulic rod to push the clamping block 24 to move along the guide rail 21 to clamp the steel shaft to be tested. The hydraulic cylinder 20 pushes the clamping block 24, so that the clamping block 24 can clamp steel shafts of different diameters. Through the combined action of the mounting hole 22, the hydraulic cylinder 20, the guide rail 21, and the clamping block 24, the applicable range of the device is expanded. Close the cabinet door 12, and then start the motor 30 through the controller 14 to make the motor... The reducer 31 drives the worm gears 33 on both sides to rotate, and the worm gears 33 then drive the worm wheel 32 and the threaded rod 34 to rotate. By setting two threaded rods 34 in the moving plate 35, the movement of the moving plate 35 is more balanced, preventing errors in the experimental data. The moving plate 35 moves along the direction of guide rail 38 and guide rail 26 to test the push and pull force of the steel shaft. Since the protective telescopic tube 23 is telescopic, it can always protect the steel shaft when the moving plate 35 moves. With the combined action of the fixed plate 15, the moving plate 35 and the protective telescopic tube 23, the fragments are prevented from flying when the steel shaft breaks, thus improving the safety of the equipment.
[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
