Description

Technical Field

[0001] The present application relates to the technical field of elastic pad testing, and in particular to a rubber elastic pad testing instrument. Background Art

[0002] Rubber elastic pads are elastic pads made of rubber materials. Rubber elastic pads are commonly used in machinery, automobiles, electronic equipment, construction and other fields to improve equipment performance, increase comfort, protect components, etc. Rubber elastic pads are mostly round, rectangular, square and ring-shaped.

[0003] After the rubber elastic pad is produced, it needs to be tested for strength to ensure that it can be used in some application scenarios, such as those under greater pressure or impact. Insufficient strength may cause the rubber pad to fail and cause safety problems. Strength testing can detect potential risks in advance. At the same time, strength testing can determine whether the quality of the rubber pad meets the standards and expected requirements, and verify the reliability of its production process and materials.

[0004] For example, the patent with publication number CN211347697U specifically discloses a rubber sealing pad strength test device, including a test bench, support feet, anti-skid pads, auxiliary storage devices, a tensile gauge, and a transparent fixing sleeve. Thus, the rubber sealing pad to be tested can be pulled, and the data on the tensile gauge can be observed at the same time, so that the tensile strength of the rubber sealing pad can be tested.

[0005] When testing a block-shaped rubber gasket, the above patent hooks the rubber gasket on the connecting hook and hook at the end of the tensile gauge, and rotates the threaded rod to provide power for the movement of the slide seat through the connecting seat, so that the rubber gasket can be pulled. However, when testing the rubber gasket, since the connecting hook and hook at the end of the tensile gauge have fewer contact points with the rubber gasket, when the rubber gasket is continuously pulled, the parts where the connecting hook and hook are hooked may produce local large deformation due to concentrated force, and the rubber gasket may even be partially torn or damaged. Therefore, it is necessary to design a rubber elastic pad tester to solve the above problems.

[0006] It should be noted that the above information disclosed in this background technology section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute the prior art. Summary of the invention

[0007] Based on the above-mentioned problems existing in the prior art, the problem to be solved by the present application is: to provide a rubber elastic pad tester to solve the problem that when the above-mentioned patent is testing the rubber sealing pad, due to the small contact positions between the connecting hook and the hook at the end of the tensile gauge and the rubber sealing pad, when continuously pulled, the parts held by the connecting hook and the hook may produce large local deformation due to concentrated force, and even the rubber sealing pad may be partially torn or damaged.

[0008] The technical solution adopted by the present application to solve its technical problems is: a rubber elastic pad tester. It mainly includes: a test bench; a clamping mechanism, which is installed on the test bench, and the clamping mechanism includes: a fixing seat, which is installed on the test bench, and the fixing seat is threadedly connected with a first screw; a first clamping unit, which is installed on the first screw, and the first clamping unit includes: a clamping seat, which is installed on the first screw, and the clamping seat has a clamping groove; a first anti-slip surface, which is installed in the clamping groove; a second screw, which is threadedly connected to the clamping seat, and a clamping plate is installed at one end of the second screw; a detection mechanism, which is installed on the test bench, and the detection mechanism has a connecting hook for fixing one end of the rubber elastic pad and a tensile gauge for strength detection of the rubber elastic pad.

[0009] Furthermore, a rocker wheel is installed on the first screw rod.

[0010] Furthermore, a second anti-slip surface is installed on a side of the clamping plate close to the first anti-slip surface.

[0011] Furthermore, the test bench is provided with slide rails on both sides of the clamping seat, a slide seat is slidably mounted on the slide rails, and the clamping seat is mounted on the slide seat.

[0012] Furthermore, the detection mechanism includes a base installed on the test bench, the dynamometer is installed on the base, and the connecting hook is installed on the dynamometer.

[0026] A first clamping unit is installed on the end of the first screw 202 away from the rocking wheel 203, and the first clamping unit includes a clamping seat 204 with a bearing installed on the end of the first screw 202 away from the rocking wheel 203, the clamping seat 204 has a clamping groove 205, and a first anti-slip surface 206 is fixedly installed at the bottom end of the inner wall of the clamping groove 205, and a second screw 207 is threadedly connected to the clamping seat 204, and a clamping plate 208 is fixedly installed on one end of the second screw 207. The clamping plate 208 is suitable for approaching or moving away from the first anti-slip surface 206 as the second screw 207 rotates, and is further suitable for fixing one end of the rubber elastic pad on the first anti-slip surface 206;

[0027] A second anti-slip surface 209 is fixedly mounted on one side of the clamping plate 208 close to the first anti-slip surface 206. The second anti-slip surface 209 and the first anti-slip surface 206 are suitable for clamping one end of the rubber elastic pad tightly to prevent the one end of the rubber elastic pad from escaping from the clamping plate 208 and the clamping groove 205.

[0028] On the test bench 1, slide rails 210 are fixedly installed on both sides of the clamping seat 204, and a slide seat 211 is slidably installed on the slide rails 210. The clamping seat 204 is fixedly installed on the slide seat 211. The clamping seat 204 is suitable for linearly moving on the slide rails 210 as the first screw 202 rotates, and the movement of the clamping seat 204 is linearly restricted, so as to be suitable for adjusting the position of the clamping seat 204.

[0029] A detection mechanism 3 is installed on the test bench 1. The detection mechanism 3 is used to perform strength detection on the rubber elastic pad. The detection mechanism 3 includes a base 301 fixedly installed on the test bench 1. A tension gauge 302 is installed on the base 301. The tension gauge 302 has a connecting hook 303. A shielding portion 304 is rotatably installed on the connecting hook 303.

[0030] The shielding portion 304 has a movable shaft, which penetrates the connecting hook 303. The shielding portion 304 is made of magnetic material. The shielding portion 304 is suitable for rotating along the movable shaft to be close to or away from the hook end and magnetically connected to the hook end.

[0031] The connecting hook 303 has a hook end, and a shielding portion 304 is rotatably mounted on the connecting hook 303. The shielding portion 304 is suitable for preventing the rubber elastic pad from breaking and flying out of the connecting hook 303 after the rubber elastic pad is tested.

A support base 306 is fixedly installed on the test bench 1, and the support base 306 is fixedly connected to the dynamometer 302. The support base 306 is used to support the dynamometer 302 and is on the same horizontal line as the clamping groove 205.

[0033] In the present application, in order to prevent the connection hook 303 from hooking one end of the rubber sealing pad so that the connection hook 303 is easy to tear the one end of the rubber sealing pad during the pulling test of the rubber sealing pad, the connection hook 303 can be set as a second clamping unit, and the second clamping unit has the same structure as the first clamping unit;

[0034] Working principle:

[0035] When testing the rubber seal, first place one end of the rubber seal in the clamping groove 205 of the first clamping unit, and at the same time fit it to the first anti-slip surface 206, then hold the second screw 207 and rotate it, so that the clamping plate 208 moves down, and fix one end of the rubber seal on the first anti-slip surface 206, and similarly clamp the other end of the rubber seal through the second clamping unit of the tensile gauge 302;

[0036] Then hold the rocking wheel 203 and rotate the first screw 202. The first screw 202 provides power for the movement of the clamping seat 204. The clamping seat 204 slides on the slide rail 210 through the slide seat 211 and moves toward the rocking wheel 203, so that the rubber sealing gasket to be tested can be pulled, and the rubber sealing gasket is fixed by the clamping groove 205 and the clamping plate 208 to increase the contact area with the rubber sealing gasket, while avoiding tearing caused by hooking the rubber sealing gasket for testing. At the same time, observe the data on the display screen 305 on the dynamometer 302, so as to detect the tensile strength of the rubber sealing gasket.

[0037] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
