Description

Technical Field

[0001] This utility model relates to the field of conductive rubber strip performance testing technology, and in particular to a device for testing the wear resistance and pressure resistance of conductive rubber strips. Background Technology

[0002] Conductive rubber strips are elastic materials composed of conductive fillers (such as carbon black, metal particles, conductive fibers, etc.) and a rubber matrix, combining conductivity with the flexibility of rubber. To ensure the reliability of their conductivity and structural integrity under complex working conditions, avoid functional failure, and guarantee application safety and durability, it is necessary to conduct necessary wear and pressure resistance tests on conductive rubber strips.

[0003] Currently, the abrasion resistance and pressure resistance tests for conductive rubber strips are conducted separately in different processes using different equipment, resulting in a lengthy testing process. Each test item needs to be performed independently, and interruptions or repetitions may occur due to equipment malfunctions or improper sample installation, further extending the testing cycle. Furthermore, separate testing requires the purchase and maintenance of multiple different testing devices, which undoubtedly increases the company's equipment procurement costs and daily maintenance expenses. Utility Model Content

[0004] Based on this, this utility model provides a device for testing the wear and pressure resistance of conductive rubber strips. It features a simple structure and ease of use. During the reciprocating linear motion of the transfer plate, the friction head repeatedly rubs the sample on the first clamping plate, while the pressure plate repeatedly presses the sample on the second clamping plate. This integrates wear resistance and pressure resistance testing, allowing for simultaneous testing of both. This avoids equipment switching and repeated installation and debugging, significantly reducing testing time. Furthermore, companies only need to purchase one device to meet their wear and pressure resistance testing needs, reducing equipment procurement costs.

[0005] To achieve the objectives of this utility model, the following technical solution is adopted:

[0006] A device for testing the wear resistance and pressure resistance of conductive rubber strips includes:

[0007] The clamping assembly includes a base, a first clamping plate fixedly mounted on the center of the top surface of the base, and a second clamping plate movably mounted on one side of the first clamping plate; both the first and second clamping plates are used for clamping samples; and

[0008] A test assembly is mounted on one side of the clamping assembly; the test assembly includes a support base mounted on one side of the first clamping plate, a transfer plate slidably connected to the support base, a friction head movably mounted on the side of the transfer plate facing the first clamping plate, a pressure plate fixedly mounted on the side of the transfer plate facing the second clamping plate, and a reciprocating push-pull device located on one side of the support base; the reciprocating push-pull device is connected to the transfer plate to drive the transfer plate to perform reciprocating linear motion on the support base; the friction head is used to repeatedly rub the sample located on the first clamping plate, and the pressure plate is used to repeatedly squeeze the sample located on the second clamping plate.

[0009] The aforementioned conductive rubber strip abrasion and pressure resistance testing device features a simple structure and ease of use. Utilizing a transfer plate in reciprocating linear motion, the friction head repeatedly rubs the sample on the first clamping plate, while the pressure plate repeatedly presses the sample on the second clamping plate. This integrates abrasion and pressure resistance testing, allowing for simultaneous testing of both instruments. This eliminates the need for equipment switching and repeated installation and debugging, significantly reducing testing time. Furthermore, companies only need to purchase one device to meet their abrasion and pressure resistance testing needs, reducing equipment procurement costs.

[0011] In one embodiment, the reciprocating push-pull device includes a motor located on one side of the support base, a turntable coaxially connected to the rotor of the motor, and a push-pull rod hinged to the periphery of the turntable; the end of the push-pull rod away from the turntable is used to hinge the transfer plate.

[0012] In one embodiment, the friction head is a ceramic friction head.

[0013] In one embodiment, the side of the friction head that comes into contact with the sample is arc-shaped.

[0014] In one embodiment, the second clamping plate is connected to the base via a horizontal manual linear slide module.

[0015] In one embodiment, the friction head is connected to the support base via a vertical manual linear slide module.

[0016] In one embodiment, the first clamping plate and the second clamping plate are perpendicular to each other. Attached Figure Description

Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0026] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Please see Figures 1 to 4 The conductive rubber strip wear and pressure resistance test device according to one embodiment of the present invention includes a clamping assembly 10 and a test assembly 20 installed on one side of the clamping assembly 10.

[0029] The clamping assembly 10 includes a base 11, a first clamping plate 12 fixedly installed in the middle of the top surface of the base 11, and a second clamping plate 13 movably installed on one side of the first clamping plate 12. Both the first clamping plate 12 and the second clamping plate 13 are used to clamp the sample 30 so that the testing assembly 20 can perform tests. The second clamping plate 13 is connected to the base 11 through a horizontal manual linear slide module 130 to achieve movable installation between the second clamping plate 13 and the base 11.

[0030] In this embodiment, the first clamping plate 12 and the second clamping plate 13 are perpendicular to each other. Specifically, the first clamping plate 12 is arranged in the horizontal direction, and the second clamping plate 13 is arranged in the vertical direction.

[0031] The test assembly 20 includes a support base 21 mounted on one side of the first clamping plate 12, a transfer plate 22 slidably connected to the support base 21, a friction head 23 movably mounted on the side of the transfer plate 22 facing the first clamping plate 12, a pressure plate 24 fixedly mounted on the side of the transfer plate 22 facing the second clamping plate 13, and a reciprocating push-pull device 25 located on one side of the support base 21; the reciprocating push-pull device 25 is connected to the transfer plate 22 to drive the transfer plate 22 to perform reciprocating linear motion on the support base 21.

[0032] In this embodiment, the friction head 23 is used to abut against the sample 30 located on the first clamping plate 12. The friction head 23 is connected to the support base 21 via a vertical manual linear slide module 230 to achieve movable installation between the friction head 23 and the support base 21. By controlling the lifting displacement of the friction head 23, the friction head 23 can effectively abut against the sample 30. In practice, the distance between the friction head 23 and the first clamping plate 12 can be adjusted via the horizontal manual linear slide module 130, and the distance between the pressure plate 24 and the second clamping plate 13 can be adjusted via the vertical manual linear slide module 230, which can easily adapt to the testing requirements of samples 30 with different thicknesses. It can be understood that the distance between the friction head 23 and the first clamping plate 12, and the distance between the pressure plate 24 and the second clamping plate 13 can also be adjusted separately.

[0033] In this embodiment, the transfer plate 22 is slidably connected to the support base 21 via a guide rail pair.

[0034] In this embodiment, the reciprocating push-pull device 25 includes a motor 251 located on one side of the support base 21, a turntable 252 coaxially connected to the rotor of the motor 251, and a push-pull rod 253 hinged to the periphery of the turntable 252; the end of the push-pull rod 253 away from the turntable 252 is used to hinge the transfer plate 22. The rotational motion of the motor 251 is transmitted to the transfer plate 22 through the turntable 252 and the push-pull rod 253. Since the movement of the transfer plate 22 is restricted by the guide rail pair, the rotational motion generated by the reciprocating push-pull device 25 is converted into reciprocating linear motion, thereby driving the transfer plate 22 to perform reciprocating linear motion along the guide rail pair. When the transfer plate 22 performs reciprocating linear motion, the friction head 23 repeatedly rubs the sample 30 located on the first clamping plate 12, and the pressure plate 24 repeatedly squeezes the sample 30 located on the second clamping plate 13. Compared with traditional performance testing methods, this invention's conductive rubber strip abrasion and pressure resistance testing device integrates abrasion resistance testing and pressure resistance testing, allowing for simultaneous performance of both tests. This avoids equipment switching and repeated installation and debugging, significantly reducing testing time. Furthermore, companies only need to purchase one device to meet their abrasion and pressure resistance testing needs, reducing equipment procurement costs.

[0035] In this embodiment, the side of the friction head 23 that abuts against the sample is arc-shaped; the friction head 23 is a ceramic friction head.

[0036] The aforementioned conductive rubber strip abrasion and pressure resistance testing device has a simple structure and is easy to use. When the transfer plate 22 performs reciprocating linear motion, the friction head 23 repeatedly rubs the sample 30 located on the first clamping plate 12, and the pressure plate 24 repeatedly presses the sample 30 located on the second clamping plate 13. This integrates abrasion resistance and pressure resistance testing, allowing for simultaneous testing of both. This avoids equipment switching and repeated installation and debugging, significantly shortening the testing time. Furthermore, companies only need to purchase one device to meet their abrasion and pressure resistance testing needs, reducing equipment procurement costs.

[0037] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0038] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
