Description

Technical Field

[0001] This application relates to the field of pad testing equipment, and more specifically, to a pad life testing device. Background Technology

[0002] The inner tube liner, also known as a liner or pressure strip, is a ring-shaped rubber strip used to protect the inner tube's mating surface from rim wear. It is installed between the inner tube and the rim, and is thicker in the middle, gradually thinning from the inside to the outside at both edges. There is a center line on the outer surface of the liner for alignment during installation, and there is also a hole on the center line for the inner tube valve to pass through. The liner does not have high requirements for the physical and mechanical properties of the rubber material, but it should have good aging resistance. Tubeless tires fixed to deep rims and ultra-low pressure tires fixed to specially structured rims do not require liners because of their tight fit.

[0003] After production, the pads need to be sampled and tested to ensure that the quality of the pads is up to standard. For example, a pad tear performance testing device disclosed in Chinese application No. 202322474948.8 can test the service life of the pads.

Detailed Implementation

[0023] The technical solution in this application embodiment is to solve the problem that the testing device can only test the tear performance of the padding tape and cannot test other properties of the padding tape, thus reducing the detection range. The overall idea is as follows:

[0024] Please see Figures 1-4 A pad service life testing device includes a durability testing component 10 and an abrasion resistance testing component 20.

[0025] Please see Figure 1 , Figure 2 and Figure 3 The durability testing assembly 10 includes a support frame 110, with a first electric gripper 130 mounted on the bottom of the support frame 110 and a second electric gripper 140 slidably connected to the top of the support frame 110. The two ends of the pad sample to be tested are clamped by the first electric gripper 130 and the second electric gripper 140 respectively. Then, the second electric gripper 140 is moved upward, and the pad is pulled up during the upward movement. The height of the rise is recorded, thereby enabling the testing of the tear resistance and durability performance of the pad.

[0026] A lifting component 120 is mounted on the support frame 110, and a second electric gripper 140 is mounted on the mounting end of the lifting component 120. The lifting component 120 includes a first cylinder 121. Two first cylinders 121 are mounted at both ends of the support frame 110. A slider 123 is fixedly connected to the cylinder rod end of each of the two first cylinders 121. The two sliders 123 are slidably connected to the opposite surfaces of the support frame 110, and a crossbar 122 is fixedly connected to the opposite surfaces of the two sliders 123. The second electric gripper 140 is mounted on the lower surface of the crossbar 122. During testing, the two first cylinders 121 are activated, causing the cylinder rod ends of the first cylinders 121 to extend, thereby causing the two sliders 123 to move upwards. As the two sliders 123 move upwards, the crossbar 122 also moves upwards, thus driving the second electric gripper 140 upwards, pulling the pad sample upwards to perform tear and durability tests on the pad.

[0027] The support frame 110 includes a base 111 and a U-shaped frame 112. Specifically, vertical mounting grooves are formed on the inner sides of both side walls of the U-shaped frame 112. Two first cylinders 121 are respectively installed inside the two mounting grooves, and two sliders 123 are slidably connected to the inner walls of the two mounting grooves. The U-shaped frame 112 is mounted on the base 111, a first electric gripper 130 is mounted on the base 111, and a second electric gripper 140 is slidably mounted on the U-shaped frame 112. The base 111 and the U-shaped frame 112 are used to install the testing device, ensuring normal testing of the pad tape.

[0028] Please see Figure 1 , Figure 2 and Figure 4 The abrasion resistance testing assembly 20 includes a mounting bracket 210, which is slidably mounted on a support bracket 110. A friction element 230 is mounted on the mounting bracket 210. After testing the tear resistance and durability of the pad, the friction element 230 is first brought into contact with the pad, and then activated, causing its friction end to rub against the pad. The time is recorded to test the abrasion resistance of the pad. The friction element 230 allows for testing of the abrasion resistance of the pad, enabling this application to test both tear resistance and durability. The testing range is wide, basically meeting the fundamental performance testing requirements of the pad, thus understanding the quality and service life of this batch of pads. The sliding connection between the mounting bracket 210 and the support bracket 110 allows for abrasion resistance testing of different parts of the pad, resulting in more accurate test data and improved test reliability.

[0029] Mounting bracket 210 includes a second cylinder 212, which is mounted on the bottom end of support bracket 110. Specifically, the cylinder rod end of the second cylinder 212 is mounted on the base 111. L-shaped moving blocks 211 are fixedly connected to the cylinder rod ends of the two second cylinders 212. Specifically, sliding grooves are provided on both outer sides of the U-shaped bracket 112, and limiting blocks 240 that cooperate with the sliding grooves are fixedly connected to the inner sides of the two L-shaped moving blocks 211. Mounting rods 213 are slidably connected to the opposing surfaces of the two L-shaped moving blocks 211. Specifically, clearance grooves are provided on the opposing surfaces of the two L-shaped moving blocks 211, and the two ends of the mounting rods 213 are slidably disposed within the two clearance grooves. Friction components 230 are mounted on the mounting rods 213. Pushing components 220 are mounted on the two L-shaped moving blocks 211, and the two pushing components 220 are respectively connected to the two ends of the mounting rods 213. The two pushing components 220 each include a third cylinder 221, which is mounted on two L-shaped moving blocks 211. Connecting rods 222 are fixedly connected to the cylinder rod ends of the two third cylinders 221, and the connecting rods 222 are fixedly connected to both ends of the mounting rod 213. The friction component 230 includes a drive motor 231 and a friction disc 232. The drive motor 231 is mounted on the mounting rod 213, and the friction disc 232 is fixedly connected to the output end of the drive motor 231. When testing the wear resistance of the pad, the second cylinder 212 is first activated, causing the L-shaped moving blocks 211 and the mounting rod 213 to move to the required testing position. Then, the third cylinder 221 is activated, causing the friction disc 232 to contact the pad. Finally, the drive motor 231 is activated, causing the friction disc 232 to rotate, thereby rubbing the pad and recording the time to test its wear resistance.

[0030] In this application, after testing the tear resistance and durability of the padding tape, the friction element 230 is first brought into contact with the padding tape, and then the friction element 230 is activated, causing its friction end to rub against the padding tape. The time is recorded to test the wear resistance of the padding tape. The friction element 230 allows for testing of the wear resistance of the padding tape, enabling this application to test both tear resistance and durability. The testing range is wide, basically meeting the fundamental performance testing requirements of the padding tape, thus understanding the quality and service life of this batch of padding tape. The sliding connection between the mounting bracket 210 and the support bracket 110 allows for wear resistance testing of different parts of the padding tape, resulting in more accurate test data and improved test reliability.

[0031] In summary, this application, through the setting of friction element 230, enables the testing of the wear resistance of the pad, and also allows for testing of the tear resistance and durability of the pad. The testing range is broad, basically meeting the fundamental performance testing requirements of the pad, thereby allowing for an understanding of the quality of this batch of pad production and its service life.

[0032] It should be noted that the specific models and specifications of the first cylinder 121, the second cylinder 212, the third cylinder 221 and the drive motor 231 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail.

[0033] The power supply and operating principle of the first cylinder 121, the second cylinder 212, the third cylinder 221 and the drive motor 231 are clear to those skilled in the art and will not be described in detail here.

[0034] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
