[0002] During the production process of car seat fabrics, random inspections are usually required to detect the wear resistance of the bushings and calculate the number of times the bushings have been used. This requires the use of an abrasion tester, which is suitable for abrasion resistance tests of various textiles, as well as leather, carpets, rubber, plastic sheets and other materials.

[0003] After checking the publication number: CN212254942U, a seat wear detection device for vehicle inspection is disclosed.

[0026] The main body component 21 includes a table top 211 fixed on the top of the processing table 1, a tooling seat 212 is installed on the upper end of the table top 211, and the bus seat cushion 3 is placed in the tooling seat 212 for positioning;

[0027] The actuator assembly 22 includes a base plate 221 disposed on the main assembly 21, and shaft seats 222 are fixed at both left and right ends of the bottom of the base plate 221. Sprocket wheels 223 are rotatably mounted at both front and rear ends of the shaft seat 222, and a chain 224 is mounted between the front and rear sprocket wheels 223. A motor 225 is mounted on the outer wall of the shaft seat 222 and is used to drive the sprocket wheel 223 to rotate. A grinding strip 226 is mounted between the mutually symmetrical chain links of the chains 224 at both ends.

[0028] The dust collecting component 23 is arranged on the execution component 22 and is used to collect the dust generated during the processing.

[0029] In this embodiment, when the grinding strip 226 contacts the bus seat cushion 3 below, the motor 225 drives the sprocket 223 to drive the chain 224 to move. The chain 224 wears the bus seat cushion 3 through the grinding strip 226 on each chain link, thereby ensuring that the grinding range of the bus seat cushion 3 is uniform and consistent, avoiding local excessive wear, and more accurately reflecting the overall wear resistance of the seat cushion.

[0030] Specifically, the actuator assembly 22 further includes a stand 227 fixed on the top of the processing table 1 , a cylinder 228 is installed on the top of the stand 227 , and an output end of the cylinder 228 is fixed to the top of the base plate 221 .

[0031] In this embodiment, the output end of the cylinder 228 can drive the actuator 22 to descend as a whole, so that the surface of the grinding strip 226 can contact the passenger car seat 3 below, and different pressures are applied thereto by lifting and lowering to different heights.

[0032] Specifically, the dust collection assembly 23 includes guide rods 231 fixed to the four corners of the top of the base plate 221 , a cover body 232 slidably mounted on the outside of the actuator 22 through the guide rods 231 , and a front end of the cover body 232 is connected to a fixed connection port 233 .

The tooling seat 212 is then rotated clockwise to drive the clamping head 213 to be clamped into the arc-shaped slot 215, thereby installing the tooling seat 212 with the bus seat cushion 3 on the top of the table top 211.

[0038] Specifically, the main body component 21 further includes a sealing groove 216 fixed on the top of the table 211 , and a sealing ring installed inside the sealing groove 216 .

[0040] The working principle and use process of the utility model are as follows: first, after putting the bus seat cushion 3 into the tooling seat 212, the tooling seat 212 is put on the table 211, and the clamping head 213 is inserted into the round hole 214, and then the tooling seat 212 is rotated clockwise to drive the clamping head 213 to clamp into the arc-shaped clamping groove 215, so that the tooling seat 212 with the bus seat cushion 3 is installed on the top of the table 211;

[0041] Then, the output end of the cylinder 228 can drive the actuator 22 to descend as a whole, so that the surface of the grinding strip 226 can contact the passenger car seat cushion 3 below; at the same time, the cover 232 is synchronously descended, and the cover 232 is pushed downward by the rebound pressure of the spring 234, and the lower end of the cover 232 is inserted into the sealing groove 216, thereby improving the sealing between the cover 232 and the table 211;

[0042] Finally, the motor 225 drives the sprocket 223 to drive the chain 224 to move, and the chain 224 wears the bus seat cushion 3 through the grinding strips 226 on each chain link, thereby ensuring that the grinding range of the bus seat cushion 3 is uniform and consistent, avoiding local excessive wear, and thus more accurately reflecting the overall wear resistance of the seat cushion.
