[0002] Automotive interior parts are often exposed to friction from everyday fabrics and leather materials. Many surfaces of automotive interior parts are coated or processed into very smooth surfaces. These coated or smooth surfaces will be scratched, become hairy, or even lose the coating and expose the base layer under the friction of everyday fabrics or leather materials, which will greatly affect the appearance. Therefore, it is necessary to test the wear resistance of these parts.

[0003] The prior art discloses a wear resistance tester for testing surface coated parts and smooth parts. This device uses a rotating shaft, one end of which is connected to the output shaft end of the motor, and the other end is equipped with a friction belt bracket. The friction belt bracket is cylindrical in shape and is sleeved on the rotating shaft. The circumferential surface of the friction belt bracket is provided with multiple friction belts extending in the radial direction of the friction belt bracket. The friction belts are evenly distributed on the circumferential surface of the friction belt bracket. This device can simulate the damage to the surface coating caused by friction of daily fabrics and leather materials.

[0004] However, this device still has some defects. The friction belt of this device can only perform rotational friction at the same position. In actual use, parts may encounter friction in various directions and types, and the rotational friction at a fixed position can only simulate a specific wear mode.

[0005] Therefore, it is necessary to provide a wear resistance tester for testing surface coated parts and smooth parts to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0024] First embodiment:

[0025] like Figure 1-3As shown, the wear resistance tester for testing surface coating parts and smooth parts provided by the present invention includes: a workbench 100, the workbench 100 includes a test table 101, a test assembly 200 is set on the test table 101, and the test assembly 200 includes a control motor 201, the control motor 201 is installed on the side wall of a limit plate 202 through a fixed bolt, the limit plate 202 is installed on the test table 101, and positioning arms 204 are also provided at both ends of the limit plate 202, a rotating shaft 208 is sleeved on the positioning arm 204, and a connecting block 207 is provided. One end is rotatably connected to the positioning arm 204 through a rotating shaft 208, and a support rod 205 is further provided at one end of the connecting block 207. A connecting ring 206 is movably sleeved on the support rod 205. One end of the connecting ring 206 is connected to the rotating plate 203. One end of the rotating plate 203 is connected to the output end of the control motor 201. A placement plate 209 is also sleeved on the rotating shaft 208. A rotating motor 210 is arranged on the side array of the placement plate 209. A rotating rod 211 is provided at the output end of the rotating motor 210. A friction plate 214 is provided on the rotating rod 211. The friction plate It is a soft film structure. In actual use, the staff places the test piece directly under the test assembly 200. At this time, the friction plate 214 resists the test piece. At this time, by starting the control motor 201, the driving of the control motor 201 drives the rotating plate 203 to rotate, and the rotation of the rotating plate 203 drives the connecting ring 206 to rotate. Since the connecting ring 206 is sleeved on the support rod 205, the connecting ring 206 can move up and down and left and right on the support rod 205, and the connecting block 207 can be rotatably mounted through the rotating shaft 208. It is installed on the positioning arm 204, thereby realizing the rotation of the connecting block 207. Through the rotation of the connecting block 207, the rotation of the rotating shaft 208 is realized. Through the rotation of the rotating shaft 208, the placement plate 209 fixedly mounted on the rotating shaft 208 is swung. Through the swing of the placement plate 209, the rotating motor 210 mounted on the end side of the placement plate 209 is swung. At the same time, by starting the rotating motor 210, the friction plate 214 is caused to rotate in a swinging manner, thereby realizing the swinging friction of the friction plate 214 against the surface of the friction test piece.

[0026] By cooperating with multiple parts within the test assembly 200, an oscillating test of the friction plate 214 can be achieved. The up and down oscillating rotation can better simulate the friction of various angles and directions that may be encountered in actual use. Compared with the traditional fixed rotating friction plate 214, the up and down oscillating friction belt can adapt to coatings of different hardness, thickness and type, making the test more flexible and comprehensive.

[0027] Second embodiment:

[0028] like Figure 2-3As shown, a positioning plate 212 is provided in the middle of the friction plate 214, and a notch is provided in the middle of the rotating rod 211. The positioning plate 212 is engaged with the notch provided in the rotating rod 211, and the two are detachably installed through the positioning bolt 213. In actual use, the staff will engage the friction plate 214 and the positioning plate 212 as a whole into the notch provided in the rotating rod 211. At this time, the positioning holes provided in the positioning plate 212 are aligned with the positioning bolts 213 provided at both ends of the rotating rod 211. Finally, the positioning plate 212 and the friction plate 214 are pre-tightened by the positioning bolt 213 to achieve the installation and fixation of the positioning plate 212 and the friction plate 214.

[0029] By cooperating with the positioning plate 212 and the rotating rod 211, in actual use, by opening a notch in the middle of the rotating rod 211 and cooperating with the positioning plate 212 and the positioning bolt 213, the friction plate 214 can be installed and replaced. Since the friction plate 214 will wear out after long-term use, the cooperation between the positioning plate 212 and the positioning bolt 213 makes it convenient for staff to replace it, thereby improving the replacement efficiency of the friction plate 214.

[0030] Third embodiment:

[0031] like Figure 1 、 Figure 3 、 Figure 4 As shown, a limit assembly 300 is further provided at the lower end of the friction plate 214. The limit assembly 300 includes a fixed seat 301 installed directly below the friction plate 214. A notch 302 is provided on the fixed seat 301. A positive and negative screw rod 303 is provided in the notch 302. A fixed plate 304 is symmetrically sleeved on the positive and negative screw rod 303. In actual use, the staff places the test piece on the table of the fixed seat 301. At this time, by adjusting the positive and negative screw rod 303 and rotating the positive and negative screw rod 303, the fixed plates 304 at both ends move toward each other. The fixed plates 304 at both ends move toward each other, and the test piece is clamped and fixed by the opposite movement of the fixed plates 304 at both ends.

[0032] By cooperating with multiple parts within the set limit assembly 300, the test piece can be firmly clamped. By firmly clamping the test piece, the position and posture of the test piece can be ensured to remain unchanged during the test, which helps to reduce test errors caused by movement or deformation of the test piece.

[0033] Fourth embodiment:

[0034] like Figure 4As shown, a rubber gasket 305 is further provided at the end of the fixed plate 304, and the rubber gasket 305 is tightly attached to the side wall of the fixed plate 304 through Velcro. In actual use, when the positive and negative screw rods 303 are adjusted and the positive and negative screw rods 303 are rotated, the fixed plates 304 at both ends move toward each other. The rubber gaskets 305 are provided at both ends of the fixed plate 304. Since the rubber gaskets 305 have good elasticity and softness, they can reduce damage to the surface of the test piece during the clamping process, avoid leaving clamp marks or causing other surface damage.

[0035] Fifth embodiment:

[0036] like Figure 1-2 As shown, a fixing seat 102 is also fixed on the test bench 101, and a limiting groove is provided on the fixing seat 102. The limiting plate 202 is embedded in the limiting groove provided on the fixing seat 102, and a positioning hole is provided on the end side of the limiting plate 202. The two are detachably installed through the pre-tightening bolt 103. During actual installation, the staff only needs to engage the limiting plate 202 into the limiting groove provided on the fixing seat 102, through the threaded hole provided on the end side of the limiting plate 202 and the pre-tightening bolt 103 provided on the end side of the fixing seat 102. When the limiting plate 202 is engaged with the fixing seat 102, the limiting plate 202 can be installed on the test bench 101 by rotating the pre-tightening bolt 103.

[0037] By using the fixed seat 102 in conjunction with the pre-tightening bolt 103, the entire test component 200 can be quickly installed on the test bench 101. When the test component 200 needs to be replaced and maintained, the test component 200 can be disassembled by simply twisting the pre-tightening bolt 103, which is convenient for subsequent maintenance by staff.

[0038] Sixth embodiment:

[0039] like Figure 1 As shown, two groups of test components 200 and limit components 300 are provided, and are symmetrically arranged on the test bench 101. In actual use, two groups of test components 200 and limit components 300 are provided, so that a double workstation is formed on the test bench 101. Multiple tests can be performed simultaneously through the double workstation, which reduces the waiting time during the test process and improves the overall test speed.

[0040] Working principle: In actual use, the staff places the test piece on the upper surface of the fixed seat 301, and at this time adjusts the positive and negative screw rods 303, and the positive and negative screw rods 303 are rotated, so that the fixed plates 304 at both ends move toward each other, and the fixed plates 304 at both ends move toward each other, so as to achieve the clamping and fixing of the test piece. When the test piece is fixed, the control motor 201 is started, and the driving of the control motor 201 is driven to rotate the rotating plate 203, and the rotation of the rotating plate 203 is driven to rotate the connecting ring 206. Since the connecting ring 206 is sleeved on the support rod 205, the connecting ring 206 is connected to the support rod 205. The support rod 205 moves up and down and left and right, and is rotatably mounted on the positioning arm 204 by the connecting block 207 through the rotating shaft 208, thereby realizing the rotation of the connecting block 207. The rotation of the rotating shaft 208 is realized by the rotation of the connecting block 207. The rotation of the rotating shaft 208 makes the placement plate 209 fixedly mounted on the rotating shaft 208 swing. The swinging of the placement plate 209 makes the rotating motor 210 mounted on the end side of the placement plate 209 swing. At the same time, the starting of the rotating motor 210 makes the friction plate 214 rotate in a swinging manner, thereby realizing the swinging friction of the friction plate 214 on the surface of the friction test piece.

[0041] The above embodiment is only one of the preferred implementation methods of the present invention and should not be used to limit the scope of protection of the present invention. Any changes or modifications that have no substantive meaning made to the main design concept and spirit of the present invention, as long as the technical problems they solve are still consistent with the present invention, should be included in the scope of protection of the present invention.
