Description

Technical Field

[0001] The invention relates to the technical field of tension detection devices, and in particular to a tension detection device for detecting octagonal lead caps. Background Art

[0002] The lead cap is a plug-in of the fuse. If the lead is loose or falls off, poor contact will be caused, thus affecting the safety of the entire circuit. The existing riveting process cannot completely prevent the lead from loosening or falling off. Therefore, when producing lead caps, it is necessary to select some lead caps as samples for random inspection to detect the quality of the lead caps; thus, a lead cap tension detection device is needed; however, after the lead cap is inspected, the existing tension detection device needs to remove the lead cap and observe the lead cap through a manual handheld magnifying glass to detect whether the lead cap is damaged. When observing the lead cap manually, the lead cap must be rotated, which increases the workload of the workers. Long-term work will make the workers feel tired. At the same time, the lead cap may not be rotated a circle, resulting in an incomplete observation of the lead cap, resulting in some unqualified lead caps being misjudged as qualified, thereby affecting the qualified rate of the lead cap products; therefore, a tension detection device for octagonal lead cap detection is proposed to solve the above problems. Summary of the invention

[0038] Embodiment 2

[0039] The technical solution is basically the same as that of the first embodiment, except that: Figure 1 , Figure 3 , Figure 4 and Figure 7 The slider 10 is a hollow structure, and a liquid outlet 11 is provided on the side wall of the slider 10. The movable plate 5 has a liquid storage chamber 17 connected to the slider 10, and a pushing component is provided in the liquid storage chamber 17. By using the pushing component, the lubricating oil in the liquid storage chamber 17 can be easily discharged from the liquid outlet 11, so as to add the lubricating oil to the slider 10, reduce the friction between the slider 10 and the slide groove 4, avoid the slider 10 from being worn due to friction, further improve the service life of the slider 10, and further improve the service life of the tension detection device; there is a pressure member 18 on the movable plate 5 that acts on the pushing component. By using the pressure member 18, it is easy to inject gas between the two piston plates 16, thereby facilitating the movement of the piston plate 16 and adding the lubricating oil to the slider 10; (wherein, the pressure member 18 includes an air pump and a pipeline, and one end of the pipeline is connected to the liquid storage chamber 17 between the two piston plates 16, which is a prior art);

[0040] In the present invention, the movable plate 5 is provided with a liquid adding hole which is in communication with the liquid storage chamber 17 , and the liquid adding hole is provided with a rubber plug, so as to facilitate adding lubricating oil into the liquid storage chamber 17 .

[0041] In the present invention, the pushing assembly includes a fixed block 15 fixed in the liquid storage chamber 17 and a piston plate 16 distributed on both sides of the fixed block 15. The fixed block 15 and the piston plate 16 are elastically connected by a tension spring 14. The use of the tension spring 14 facilitates the resetting of the piston plate 16.

[0042] In the present invention, a hard film 25 for sealing is provided in the liquid outlet 11 of the slider 10, so as to seal the liquid outlet 11 and prevent the lubricating oil in the liquid storage chamber 17 from flowing out; (the hard film 25 utilizes the principle of a heart valve, which is the same as the principle of a bicycle valve core. When there is no force, it is gathered together and in a closed state; when subjected to external force, the film is forced to open outward to form a channel, which is a prior art).

[0043] Working principle: When the present invention is used, the lead cap is vertically placed on two tension tester bodies 3, and the lead wires at both ends of the lead cap are clamped and fixed by the fixing mechanism of the tension tester body 3; then the electric telescopic rod 8 is opened, and the movable plate 5 is driven to move upward by the contraction of the movable end of the electric telescopic rod 8, so as to pull the lead cap. When the tension of the lead cap reaches the preset value of the load sensor, it is processed by the processor inside the load sensor, and then the controller controls the electric telescopic rod 8 to stop;

[0044] Then, the electric telescopic rod 29 is opened, and the rectangular frame 22 is driven to move by the contraction of the movable end of the electric telescopic rod 29. The movement of the rectangular frame 22 is divided into two processes:

[0045] Process 1: When the rectangular frame 22 moves first, the movable block 26 moves under the action of the extrusion spring 27, thereby moving the bar-shaped toothed plate 24, further driving the gear 13 to rotate, and the rotation of the gear 13 drives the telescopic member 19 to rotate, and then drives the arc-shaped mounting plate 6 to rotate, thereby rotating the magnifying glass 12, wherein the limiting rod 21 at the rear end of the bar-shaped toothed plate 24 moves from one end of the cavity of the bar-shaped toothed plate 24 to the other end, at this time, the arc-shaped mounting plate 6 rotates 90°, and at the same time, the teeth 23 on the rectangular frame 22 mesh with the gear 2 20;

[0046] Process 2: The continued movement of the rectangular frame 22 will cause the teeth 23 to move, which in turn drives the gear 2 20 to rotate, thereby driving the shaft 7 to rotate, and further driving the lead cap to rotate. When all the teeth 23 and the gear 2 20 have moved, the lead cap rotates 360°, so that it is convenient to conduct a comprehensive inspection of the lead cap; then observe the lead cap through the magnifying glass 12 to observe whether the lead cap is broken;

[0047] After the lead cap tension test is completed, the rectangular frame 22 is reset by the action of the electric telescopic rod 29, thereby resetting the arc-shaped mounting plate 6 to prevent the magnifying glass 12 from affecting the lead cap feeding;

[0048] Among them, when the slider 10 needs to be added with lubricating oil, the air pump in the pressure-applying part 18 is turned on, and then the gas is pumped between the two piston plates 16 to increase the pressure between the piston plates 16, and then the piston plates 16 are pushed to move, so that the lubricating oil in the liquid storage chamber 17 flows to the slider 10 through the liquid outlet 11, so that the slider 10 is added with lubricating oil, the friction between the slider 10 and the slide groove 4 is reduced, which is beneficial to the sliding of the movable plate 5, and can also increase the service life of the slider 10.

[0049] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
