Description

Technical Field

[0002] The insertion and extraction force testing machine is suitable for various low-temperature testing environments required for products such as wires, cables, and electrical accessories. Its main function is to test the force characteristics of insertion and extraction components during the insertion and extraction process, thereby evaluating whether the product's insertion and extraction performance meets relevant standards. With the rapid development of the electronics industry, the application range of connectors and insertion / extraction components is constantly expanding, and the market is placing higher demands on their quality and performance. However, current insertion and extraction force testing equipment still has the following shortcomings in practical applications.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Please see the appendix Figure 1 - Appendix Figure 6 The present invention provides a fully automatic insertion and extraction force testing machine, including a machine base 1. A support rod 10 is fixedly connected inside the machine base 1. A fixing ring 4 is provided on the outer wall of the support rod 10. A fixing crossbar 2 is provided between the two fixing rings 4. A fixing bolt 6 is installed inside the fixing crossbar 2. A load cell 5 is installed at one end of the fixing bolt 6. A movable crossbar 3 is slidably connected to the outer wall of the support rod 10. An upper and lower limit adjustment mechanism is provided on one side of the outer wall of the movable crossbar 3.

[0031] The upper and lower limit adjustment mechanism includes a sliding frame 30, an adjusting rod 46 fixedly connected to the outer wall of the sliding frame 30, a second connecting frame 25 slidably connected to the outer wall of the adjusting rod 46, the upper surface of the second connecting frame 25 fixedly connected to the inner top of the machine base 1, a second connecting block 26 fixedly connected to the outer wall of the adjusting rod 46, a spring 27 fixedly connected to the outer wall of the second connecting block 26, one end of the spring 27 fixedly connected to the outer wall of the second connecting frame 25, a lower limit adjusting ring 28 installed on the outer wall of the adjusting rod 46 near the machine base 1, a lower limit adjusting ring 29 installed on the outer wall of the adjusting rod 46 near the lower limit adjusting ring 28, an upper limit adjusting ring 32 installed on the outer wall of the adjusting rod 46 away from the machine base 1, and an upper limit adjusting ring 31 installed on the outer wall of the adjusting rod 46 near the upper limit adjusting ring 32.

[0032] Specifically, the fixing ring 4 is fastened to the support rod 10 by bolts. The fixing ring 4 slides on the support rod 10 by adjusting its tightness, causing the fixing crossbar 2 to slide on the support rod 10, thereby adjusting the position of the fixing crossbar 2 and the height of the load cell 5. The moving crossbar 3 slides on the support rod 10, causing the sliding frame 30 to slide on the adjusting rod 46. This causes the sliding frame 30 to contact the lower limit adjusting ring 29 and the upper limit adjusting ring 31, thus moving the adjusting rod 46. The adjusting rod 46 then moves within the second connecting frame 25, causing the second connecting block 26 to slide within the second connecting frame 25 and contact the sensor, stopping the moving crossbar 3. Adjusting the position of the upper limit adjusting ring 31 on the adjusting rod 46 adjusts the upward movement of the moving crossbar 3. Adjusting the position of the lower limit adjusting ring 29 on the adjusting rod 46 adjusts the downward movement of the moving crossbar 3. The spring 27 moves the second connecting block 26, thus resetting the adjusting rod 46.

[0033] Please see the appendix Figure 1 -Appendix Figure 4A fixed rod 12 is fixedly connected to the inner top of the machine base 1. A first connecting frame 13 is fixedly connected to the lower surface of the fixed rod 12. A sliding seat 14 is slidably connected inside the first connecting frame 13. A motor 16 is fixedly connected to the upper surface of the sliding seat 14. A transmission wheel 18 is fixedly connected to the output end of the motor 16. A first rotating rod 15 is rotatably connected inside the sliding seat 14. The outer wall of the first rotating rod 15 is threaded into the inside of the first connecting frame 13. A second rotating rod 22 is rotatably connected inside the first connecting frame 13. One end of the second rotating rod 22 is fixedly connected to... There is a driven wheel 19, and a threaded rod 24 is fixedly connected to the other end of the driven wheel 19. A threaded block 23 is threadedly connected to the outer wall of the threaded rod 24. A moving rod 17 is fixedly connected to the outer wall of the threaded block 23. A first connecting block 11 is fixedly connected to the outer wall of the moving rod 17.

A limit frame 20 is fixedly connected to the inner top of the first connecting frame 13. A limit wheel 21 is rotatably connected to the outer wall of the limit frame 20. A belt is sleeved on the outer wall of the limit wheel 21.

[0034] Specifically, the output of motor 16 drives the belt to rotate the driven wheel 19, which in turn drives the second rotating rod 22 to rotate. The second rotating rod 22 rotates within the first connecting frame 13, while the threaded rod 24 rotates within the threaded block 23. This causes the threaded block 23 to move the moving rod 17 within the machine base 1, which in turn pushes the first connecting block 11 to move the moving crossbar 3 onto the support rod 10. By twisting the first rotating rod 15, it rotates on the sliding seat 14 and the first connecting frame 13, causing the sliding seat 14 to slide on the first connecting frame 13. This causes the transmission wheel 18 to move, which in turn pulls the belt to move, causing the belt to slide on the limit wheel 21, thereby achieving the effect of adjusting the belt tension.

[0035] Please see the appendix Figure 1 and attached Figure 8 One end of the load cell 5 is fixedly connected to a third fixing plate 42, and the lower surface of the third fixing plate 42 is fixedly connected to a second fixing frame 43. The second fixing frame 43 is internally threaded with a fourth adjusting rod 44, and one end of the fourth adjusting rod 44 is rotatably connected to a fourth fixing plate 45. The interior of the fourth fixing plate 45 is slidably connected to the outer wall of the second fixing frame 43.

[0036] Specifically, by rotating the fourth adjusting rod 44 within the second fixed frame 43, one end of the fourth adjusting rod 44 rotates on the fourth fixed plate 45, thereby causing the fourth fixed plate 45 to slide on the second fixed frame 43, thus fixing one end of the test sample by the movement of the fourth fixed plate 45.

[0037] Please see the appendix Figure 1 and attached Figure 7A fixture plate 7 is fixedly connected to the upper surface of the movable crossbar 3. A first fixing plate 33 is mounted on the upper surface of the fixture plate 7. A first adjusting frame 34 is fixedly connected to the upper surface of the first fixing plate 33. A second adjusting frame 37 is slidably connected to the upper surface of the first adjusting frame 34. A first adjusting rod 35 is threadedly connected to the inside of the second adjusting frame 37. The outer wall of the first adjusting rod 35 is rotatably connected to the inside of the first adjusting frame 34. A sliding block 38 is slidably connected to the upper surface of the second adjusting frame 37. A second adjusting rod 36 is threadedly connected to the inside of the sliding block 38. The outer wall of the second adjusting rod 36 is rotatably connected to the inside of the second adjusting frame 37. A first fixing frame 39 is fixedly connected to the upper surface of the sliding block 38. A third adjusting rod 40 is threadedly connected to the inside of the first fixing frame 39. One end of the third adjusting rod 40 is rotatably connected to a second fixing plate 41. The inside of the second fixing plate 41 is slidably connected to the outer wall of the first fixing frame 39. A movable support leg 9 is fixedly connected to the lower surface of the machine base 1. An operation panel 8 is fixedly connected to the outer wall of the machine base 1.

[0038] Specifically, by rotating the first adjusting rod 35 within the second adjusting frame 37, the second adjusting frame 37 slides on the first adjusting rod 35, thereby adjusting the position of the sliding block 38. By rotating the second adjusting rod 36 within the sliding block 38, the sliding block 38 slides on the second adjusting frame 37, thereby moving the first fixed frame 39. Then, by rotating the third adjusting rod 40 within the first fixed frame 39, the second fixed plate 41 slides on the first fixed frame 39, thus facilitating the fixation of one end of the test sample.

[0039] Working principle: First, the fixed ring 4 slides on the support rod 10 by adjusting its tightness, thereby causing the fixed crossbar 2 to slide on the support rod 10, thus adjusting the position of the fixed crossbar 2 and the height of the load cell 5. Then, by rotating the fourth adjusting rod 44 within the second fixed frame 43, one end of the fourth adjusting rod 44 rotates on the fourth fixed plate 45, causing the fourth fixed plate 45 to slide on the second fixed frame 43. This movement of the fourth fixed plate 45 fixes one end of the test sample. By rotating the first adjusting rod 35 within the second adjusting frame 37, the second adjusting frame 37 slides on the first adjusting rod 35. The position of the sliding block 38 is then adjusted by rotating the second adjusting rod 36 within the sliding block 38, causing the sliding block 38 to slide on the second adjusting frame 37, thereby moving the first fixed frame 39. Then, by rotating the third adjusting rod 40 within the first fixed frame 39, the second fixed plate 41 is pushed to slide on the first fixed frame 39, thus facilitating the fixation of one end of the test sample. The output of the motor 16 then drives the driven wheel 19 to rotate via a belt, which in turn drives the second rotating rod 22 to rotate within the first connecting frame 13, simultaneously causing the threaded rod 24 to... Rotating within the threaded block 23 causes the threaded block 23 to move the moving rod 17 within the machine base 1, thereby pushing the first connecting block 11 to slide the moving crossbar 3 on the support rod 10, thus achieving the effect of testing the test sample. This causes the sliding frame 30 to slide on the adjusting rod 46, bringing it into contact with the lower limit adjusting ring 29 and the upper limit adjusting ring 31, thereby moving the adjusting rod 46. This causes the adjusting rod 46 to move within the second connecting frame 25, causing the second connecting block 26 to slide within the second connecting frame 25, thus contacting the sensor and stopping the moving crossbar 3. The movement is then adjusted... The position of the upper limit adjustment ring 31 on the adjustment rod 46 adjusts the upward movement of the moving crossbar 3. The position of the lower limit adjustment ring 29 on the adjustment rod 46 adjusts the downward movement of the moving crossbar 3. The spring 27 drives the second connecting block 26 to move, thereby achieving the effect of resetting the adjustment rod 46. By twisting the first rotating rod 15 to rotate on the sliding seat 14 and the first connecting frame 13, the sliding seat 14 slides on the first connecting frame 13, thereby driving the transmission wheel 18 to move, thereby pulling the belt to move, causing the belt to slide on the limit wheel 21, thereby achieving the effect of adjusting the belt tension.
