Description

Technical Field

[0001] The utility model relates to the technical field of mini waterproof plug tension testing, in particular to a tension tool with a positioning function. Background Art

[0002] The function of the mini waterproof plug is to prevent water from overflowing or leaking. It is usually used in waterproof equipment, faucets, water pipe joints and other places, which can effectively seal the water flow and prevent the water from overflowing or leaking through the plug mouth. This can avoid wasting water resources and reduce the risk of water damaging other items or equipment. Mini waterproof plugs need to be subjected to tensile testing during production to ensure that the mini waterproof plug can withstand a certain amount of tension during use and will not fall off or be damaged easily.

[0003] At present, when conducting a tensile test on a mini waterproof plug, two fixing clamps are usually used to fix the two ends of the waterproof plug, and then the clamps are pulled at a uniform speed and the tensile force is tested according to the force gauge. However, since the mini waterproof plug is small, it is troublesome to fix it with a fixing clamp, and it is easy to have a loose fixation. For this reason, we propose a tensile tooling with a positioning function. Utility Model Content

[0025] The auxiliary component 2 includes an active frame 21, which is fixed on the surface of the fixed platform 101. An L-shaped rod 22 is fixed on one side of the active frame 21 close to the center of the test bench 1. The L-shaped rod 22 penetrates the sleeve rod 23 and is slidably connected to the sleeve rod 23. A support plate 216 is fixed on one side of the sleeve rod 23. A return spring 24 is fixed on the other side of the sleeve rod 23. One end of the return spring 24 away from the sleeve rod 23 is fixed to the surface of the L-shaped rod 22. An L-shaped clamping rod 25 is fixed on the side of the sleeve rod 23 close to the active frame 21. The L-shaped clamping rod 25 penetrates the active frame 21. The active frame 21 is penetrated by the moving rod 26 and is slidably connected to the moving rod 26. A fixed spring 24 is fixed on the inner wall of the active frame 21. Spring 27, one end of the fixed spring 27 away from the active frame 21 is fixed to the surface of the moving rod 26, a fixed disk 28 is fixed on the side of the moving rod 26 close to the support plate 216, a rotating disk 29 is rotatably installed on the side of the fixed disk 28 away from the moving rod 26, the fixed disk 28 and the moving rod 26 are penetrated by the rotating rod 210 and are rotatably connected with the rotating rod 210, the rotating rod 210 is fixed to the right side of the rotating disk 29, an arc groove 211 is opened on the rotating disk 29, a vertical groove 212 is opened on the side of the fixed disk 28 close to the rotating disk 29, a support rod 213 is slidably installed on the inner side of the vertical groove 212, the support rod 213 passes through the arc groove 211, and a spiral groove 211 is opened on the surface of the rotating rod 210 4. A slide bar 215 is slidably installed on the inner side of the spiral groove 214. The end of the slide bar 215 away from the spiral groove 214 penetrates the moving rod 26 and is fixed on the inner wall of the active frame 21. When the mini waterproof plug is placed on the side of the active frame 21, and the mini waterproof plug is pushed to contact the supporting plate 216, the supporting plate 216 moves with the sleeve rod 23 to the side close to the L-shaped rod 22. When the sleeve rod 23 cannot move further, the mini waterproof plug cannot be pushed further. At this time, the hole of the mini waterproof plug is exactly at the position of the moving rod 26. At this time, the sleeve rod 23 and the L-shaped clamping rod 25 are completely withdrawn from the clamping groove 7 on the surface of the moving rod 26, and the limit on the moving rod 26 is released. Under the action of the fixed spring 27, the moving rod 26 moves to the side close to the center of the test bench 1. At this time, since the sliding rod 215 is fixed, the rotating rod 210 moves with the moving rod 26, and then the sliding rod 215 can slide in the spiral groove 214, so that the rotating rod 210 rotates, and the rotating rod 210 drives the turntable 29 to rotate together. At this time, since the support rod 213 is limited by the vertical groove 212, when the turntable 29 rotates, it can contact the support rod 213 through the arc groove 211 opened by itself, so that the support rod 213 moves along the vertical groove 212 to the side away from the center of the turntable 29, and the support rod 213 contacts the inner side of the mini waterproof plug to fix and position the mini waterproof plug.

When the sleeve rod 23 cannot move further, the mini waterproof plug cannot be pushed further. At this time, the hole of the mini waterproof plug is exactly at the position of the moving rod 26. At this time, the sleeve rod 23 and the L-shaped clamping rod 25 are completely withdrawn from the clamping groove 7 on the surface of the moving rod 26, and the limit on the moving rod 26 is released. Under the action of the fixing spring 27, the moving rod 26 moves to the side close to the center of the test bench 1. At this time, since the sliding rod 215 is fixed, the rotating rod 210 moves with the moving rod 26, and then the sliding rod 2 15 can slide in the spiral groove 214, so that the rotating rod 210 rotates, and the rotating rod 210 drives the turntable 29 to rotate together. At this time, since the support rod 213 is limited by the vertical groove 212, when the turntable 29 rotates, it can contact the support rod 213 through the arc groove 211 opened by itself, so that the support rod 213 moves along the vertical groove 212 to the side away from the center of the turntable 29, and the support rod 213 contacts the inner side of the mini waterproof plug to fix the mini waterproof plug. By controlling the electric push rod 5 to apply a moving force to the moving platform 102, the distance between the two sets of auxiliary components 2 can be increased, so that the fixed mini waterproof plug can be tested for tension, and the tension borne by the mini waterproof plug can be clearly obtained through the force gauge 4.

[0029] After the detection is completed, the electric push rod 5 is controlled to drive the moving platform 102 to reset, and the moving rod 26 is pulled to reset, so that the sliding rod 215 slides in the opposite direction in the spiral groove 214, and the rotating rod 210 is controlled to rotate in the opposite direction, so that the support rod 213 is reset. When the moving rod 26 is reset, the L-shaped clamping rod 25 is inserted into the clamping groove 7 on the surface of the moving rod 26 to limit the moving rod 26, and the device reset is completed.
