Abstract
Description
Technical Field
[0001] This utility model relates to the field of rubber seal testing technology, and in particular to a rubber seal testing device. Background Technology
[0002] Rubber seals are components made of rubber material used to prevent fluid (liquid or gas) leakage or to prevent external impurities (such as dust and moisture) from entering the system. Their main working principle relies on the elastic deformation of the rubber material to fill the gaps between the sealing interfaces, thereby achieving a seal.
[0003] As disclosed in announcement number CN222258997U, a device for testing the tensile properties of rubber seals includes a hollow workbench. A mounting plate is fixed to the top of the workbench's side wall. A cylinder is fixed to the top wall of the mounting plate. A slide rail is fixed to the top wall of the workbench, and a slider is slidably mounted on the slide rail. A mounting block is fixed to the top wall of the slider. The movable end of the cylinder is fixedly connected to one side of the mounting block. An electronic tensile gauge is fixed to the top wall of the mounting block. A vertical plate is fixed to the side of the workbench's top wall away from the mounting plate. The connecting mechanism of this invention is used to install the rubber seal to be tested. The connecting mechanism can install strip-shaped or ring-shaped rubber seals, making installation convenient and quick, with a wide range of applications. The protective layer prevents the rubber seal from breaking and popping out during tensile property testing, thus avoiding accidental injury to workers. This ensures high safety.
[0004] However, the aforementioned patent uses hooks and clamps to clamp and fix ring-shaped and strip-shaped rubber parts, but it can only be used to fix and test rubber parts with these two characteristics. It cannot be used to test other irregularly shaped seals, so the scope of application is small. Therefore, a rubber seal detection device is needed. Utility Model Content
[0005] The purpose of this invention is to provide a rubber seal testing device that solves the problem that existing technologies can only clamp and fix ring-shaped and strip-shaped rubber parts.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber seal testing device, comprising a worktable, a cylinder, and an electronic force gauge fixed to the output end of the cylinder. The output end of the electronic force gauge is provided with an end clamping component for clamping the rubber seal. The end clamping component includes a fixed shell, a screw, an upper clamping plate, a connecting component, a lower clamping plate, and a stabilizing rod. The screw passes through the top of the fixed shell and is connected to the upper clamping plate. The upper clamping plate is connected to the lower clamping plate through the connecting component. The stabilizing rods symmetrically arranged at the bottom of the lower clamping plate pass through the bottom of the fixed shell.
[0007] Furthermore, a rotating disk is fixedly connected to the top end of the screw, and the bottom end of the screw is rotatably connected to the top of the upper clamping plate.
[0008] Furthermore, the connecting component includes a first connecting rod, a connecting base, and a second connecting rod, with the first connecting rod connected to the second connecting rod via the connecting base.
[0009] Furthermore, the top of the worktable is also provided with a tail clamping component that has the same clamping function as the end clamping component.
[0010] Furthermore, the bottom of the electronic tension meter is provided with a sliding block, and the outer wall of the sliding block is fitted with a limiting shell, and the top of the worktable is fixedly connected to the bottom of the limiting shell.
[0011] Furthermore, the limiting shell is provided with a sliding groove that matches the sliding block.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The operator rotates the rotating disc to make the screw rotate inside the fixed shell, pushing the upper clamping plate downward. At the same time, the upper clamping plate, under the connection of the connecting parts, causes the lower clamping plate to move closer or further away from the upper clamping plate. The stabilizing rod serves to stabilize the movement of the lower clamping plate and can clamp the end of the seal. Then, the tail clamping part with the same function fixes the tail of the seal. The cylinder is activated to make the electronic tension gauge and sliding block slide along the inside of the limiting shell to measure the value of the clamped and fixed rubber part.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] This utility model relates to a rubber seal testing device, including a workbench 1, a cylinder 2, and an electronic tension meter 3 fixed to the output end of the cylinder 2. The cylinder 2 is fixedly connected to the side wall of the workbench 1, and the electronic tension meter 3 is fixedly connected to the output end of the cylinder 2.
[0021] Preferably, in order to facilitate the movement of the electronic force gauge 3, a sliding block 4 is fixedly connected to the bottom of the electronic force gauge 3, and a limiting shell 5 is slidably connected to the outer wall of the sliding block 4. The limiting shell 5 has a sliding groove that matches the sliding block 4, so that the electronic force gauge 3 drives the sliding block 4 to move in the sliding groove of the limiting shell 5, ensuring its movement position.
[0022] Preferably, in order to fix the rubber sealant, the output end of the electronic tensile tester 3 is fixedly connected to an end clamping component 6, and the top of the worktable 1 is fixedly connected to a tail clamping component 7 that has the same clamping function as the end clamping component 6, so as to fix the two ends of the tested rubber sealant.
[0023] Among them, such as Figure 3 As shown, the end clamping component 6 includes a fixed shell 601. The top of the fixed shell 601 is spirally connected to the outer wall of the screw 602. A rotating disk 603 is fixedly connected to the top of the screw 602. An upper clamping plate 604 is rotatably connected to the bottom of the screw 602. A connecting component 605 is movably connected to the outer wall of the upper clamping plate 604. A lower clamping plate 606 is movably connected to the bottom of the connecting component 605. A stabilizing rod 607 is fixedly connected to the bottom of the lower clamping plate 606. The rotation of the screw 602 causes the upper clamping plate 604 to move opposite to the lower clamping plate 606 under the connection of the connecting component 605, thereby achieving the purpose of clamping. The stabilizing rod 607 serves to stabilize the movement of the lower clamping plate 606.
[0024] Among them, such as Figure 4 As shown, the connecting component 605 includes a first connecting rod 6051. One end of the first connecting rod 6051 is movably connected to an upper clamping plate 604, and the other end of the first connecting rod 6051 is movably connected to a connecting base 6052. The bottom of the connecting base 6052 is movably connected to a second connecting rod 6053, and the bottom end of the second connecting rod 6053 is movably connected to a lower clamping plate 606, which serves to pull the lower clamping plate 606 to move relative to each other, so as to ensure that the seals of different specifications are clamped and fixed.
[0025] In practical use: the operator rotates the rotating disk 603 to make the screw 602 rotate inside the fixed shell 601, pushing the upper clamping plate 604 to move downward. At the same time, the upper clamping plate 604 will be connected by the connecting component 605 to make the lower clamping plate 606 move closer or further away from the upper clamping plate 604. The stabilizing rod 607 serves to stabilize the movement of the lower clamping plate 606 and can clamp the end of the seal. Then, the tail clamping component 7 with the same function fixes the tail of the seal. The cylinder 2 is activated to slide the electronic tension meter 3 and the sliding block 4 along the inside of the limiting shell 5 to measure the value of the clamped and fixed rubber part.
