Description

Technical Field

[0001] This utility model relates to the field of slider technology, and in particular to a slider performance testing device. Background Technology

[0002] A slider is a component that moves linearly on a guide rail or groove. It usually has a certain shape and size to adapt to different application scenarios. It is generally made of metal, plastic or composite material and has high strength and wear resistance. A slider performance testing device is a device for testing various performance indicators of a slider. The most common testing method is to test the slider with a dial indicator.

[0003] However, when using a dial indicator for testing, the dial indicator is usually positioned in a fixed location, and can only test specific positions of the slider. The condition of different positions of the slider can vary. Testing only a specific position cannot obtain information about the overall state of the slider, and it is impossible to accurately judge the overall performance of the slider. Therefore, we need to consider how to solve this problem. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a slider performance testing device. This device is equipped with a rack and pinion structure to adjust the height of the first dial indicator to accommodate slider bodies of different heights. It also has a drive bevel gear and a driven bevel gear structure to adjust the movement distance of the second dial indicator to accommodate slider bodies of different widths.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A slider performance testing device includes a worktable, a testing platform fixedly connected to the upper end of the worktable, a guide rail mounted on the upper end of the testing platform, a slider body slidably connected to the guide rail, a first fixed plate fixedly connected to the upper end of the worktable, an adjustment groove formed in the first fixed plate, a U-shaped plate slidably connected to the inner wall of the adjustment groove, a lifting plate fixedly connected to the upper end of the U-shaped plate, two electric telescopic rods mounted on the side wall of the lifting plate, the telescopic ends of the two electric telescopic rods being fixedly connected to a first dial indicator, a second fixed plate fixedly connected to the upper end of the worktable, a sliding groove formed on one side wall of the second fixed plate, a first threaded rod rotatably connected between the inner top and inner bottom of the sliding groove, a movable plate threadedly connected to the first threaded rod, a movable groove formed at the upper end of the movable plate, a second threaded rod rotatably connected between the two inner walls of the movable groove, a movable block threadedly connected to the second threaded rod, and a second dial indicator fixedly connected to the upper end of the movable block.

Detailed Implementation

[0023] 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.

[0024] Reference Figures 1-7A slider performance testing device includes a worktable 1, a testing platform 2 fixedly connected to the upper end of the worktable 1, a guide rail 3 mounted on the upper end of the testing platform 2, and a slider body 4 slidably connected to the guide rail 3. During testing, the slider body 4 is driven to slide on the guide rail 3 by an external driving device. A first fixing plate 5 is fixedly connected to the upper end of the worktable 1. An adjustment groove 6 is provided in the first fixing plate 5. A U-shaped plate 7 is slidably connected to the inner wall of the adjustment groove 6. A rack 8 is fixedly connected to one side wall of the U-shaped plate 7. A sleeve 9 is rotatably connected to the inner wall of the adjustment groove 6. A gear 10 is fixedly connected to the outer wall of the sleeve 9. The gear 10 meshes with the rack 8. An insert rod 11 is inserted into the sleeve 9. The inner wall of one side of the adjustment groove 6 is provided with a slot 12 that cooperates with the insertion rod 11. One end of the insertion rod 11 extends to the outside and is fixedly connected to the first knob 13. The outer wall of the insertion rod 11 is fitted with a spring 14. The two ends of the spring 14 are elastically connected to the first fixing plate 5 and the first knob 13 respectively. The upper end of the U-shaped plate 7 is fixedly connected to the lifting plate 15. Pulling the first knob 13 causes the insertion rod 11 to disengage from the slot 12. At this time, the first knob 13 can be rotated to make the sleeve 9 rotate. Since the gear 10 meshes with the rack 8, the U-shaped plate 7 can be driven to slide up and down in the adjustment groove 6 to realize the adjustment of the height of the lifting plate 15 to adapt to the slider body 4 of different heights.

[0025] When the first knob 13 is released, the spring 14 pushes the insert rod 11 back into the slot 12, firmly locking the sleeve 9 and the U-shaped plate 7 in place, ensuring the accuracy and stability of the test data. Two electric telescopic rods 16 are installed on the side wall of the lifting plate 15. The telescopic ends of the two electric telescopic rods 16 are fixedly connected to a first dial indicator 17. The testing head of the first dial indicator 17 abuts against the upper surface of the slider body 4. By extending and retracting the electric telescopic rods 16, the first dial indicator 17 can be moved, thereby allowing for testing at different positions on the upper surface of the slider body 4. The upper end of the worktable 1 is fixedly connected to... There is a second fixed plate 18, and a sliding groove 19 is provided on one side wall of the second fixed plate 18. A first threaded rod 20 is rotatably connected between the inner top and inner bottom of the sliding groove 19. A motor 21 is installed on the upper end of the second fixed plate 18. The motor 21 is a servo motor. The end of the output shaft of the motor 21 extends into the interior of the sliding groove 19 and is fixedly connected to the upper end of the first threaded rod 20. A moving plate 22 is threadedly connected to the first threaded rod 20. A moving groove 23 is provided on the upper end of the moving plate 22. A second threaded rod 24 is rotatably connected between the inner walls of the two sides of the moving groove 23. A moving block 25 is threadedly connected to the second threaded rod 24.

[0026] The upper end of the movable block 25 is fixedly connected to a second dial indicator 26, the measuring head of the second dial indicator 26 abuts against the side of the slider body 4. The inner wall of the movable groove 23 is rotatably connected to a rotating shaft 27, the outer wall of the rotating shaft 27 is fixedly connected to a driving bevel gear 28, and the outer wall of the second threaded rod 24 is fixedly connected to a driven bevel gear 29. The driving bevel gear 28 and the driven bevel gear 29 mesh. One end of the rotating shaft 27 extends to the outside and is fixedly connected to a second knob 30. The second knob 30 is provided with a rubber layer, which is connected to the first threaded rod. Rotating the second knob 20 allows the movable plate 22 to move vertically, enabling the second dial indicator 26 to detect different side positions of the slider body 4, greatly improving the comprehensiveness of the detection. Furthermore, by rotating the second knob 30, the rotating shaft 27 and the driving bevel gear 28 are driven to rotate, which in turn drives the driven bevel gear 29 to rotate. In this way, the second threaded rod 24 also rotates, realizing the horizontal position adjustment of the movable block 25 and the second dial indicator 26 to adapt to slider bodies 4 of different widths.

[0027] In this invention, when in use, pulling the first knob 13 causes the insert rod 11 to overcome the elastic force of the spring 14 and disengage from the slot 12, so that the sleeve 9 is no longer locked by the insert rod 11. At this time, rotating the first knob 13 causes the sleeve 9 to rotate, which in turn causes the gear 10 to rotate. The rotation of the gear 10 causes the rack 8 that meshes with it to move, which in turn causes the U-shaped plate 7 to move. The lifting plate 15 will also move accordingly, thereby realizing the adjustment of the height of the electric telescopic rod 16 and the first dial indicator 17 to adapt to the slider body 4 of different heights. After adjusting to the appropriate height, releasing the first knob 13 causes the spring 14 to return to its deformation and pushes the insert rod 11 back into the slot 12, firmly locking the position of the sleeve 9 and the U-shaped plate 7, ensuring that the height of the first dial indicator 17 will not change during subsequent testing.

[0028] When it is necessary to test different positions on the upper end of the slider body 4, the electric telescopic rod 16 is activated. By controlling the extension and retraction of the electric telescopic rod 16, the first dial indicator 17 is moved on the upper end face of the slider body 4, so that the detection head of the first dial indicator 17 can contact different positions on the upper end face of the slider body 4, thereby measuring the relevant performance parameters at different positions on the upper end face of the slider body 4.

[0029] Rotating the second knob 30 causes the rotating shaft 27 to rotate, which in turn causes the driving bevel gear 28 to rotate. The driving bevel gear 28 meshes with the driven bevel gear 29, thus driving the driven bevel gear 29 and the second threaded rod 24 to rotate. The rotation of the second threaded rod 24 causes the moving block 25 to move, which in turn causes the second dial indicator 26 to move, thereby achieving the horizontal position adjustment of the second dial indicator 26 to adapt to slider bodies 4 of different widths.

[0030] When it is necessary to test different positions on the side of the slider body 4, the motor 21 is started, which drives the first threaded rod 20 to rotate, thereby causing the moving plate 22 to move up and down, and driving the second dial indicator 26 to move on the side of the slider body 4, so that the detection head of the second dial indicator 26 can contact different positions on the side of the slider body 4, thereby measuring the relevant performance parameters at different positions on the side of the slider body 4.

[0031] 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.
