[0002] Generally, the floor of a vehicle interior is covered with a carpet for anti-slip. When a driver is driving, the sole of the foot is placed on the accelerator or clutch, and the heel supports on the carpet. When stepping on the accelerator, clutch or brake, or switching between the accelerator and brake, relative friction always occurs between the heel and the carpet, resulting in carpet wear.

[0003] Therefore, before leaving the factory, the carpet needs to be subjected to wear testing to evaluate the service life of this batch of carpets and to determine whether this batch of carpets meets the factory standards.

[0004] At present, there is no special experimental equipment for testing the wear resistance of carpets and heels on the market. General equipment requires manual wear resistance testing, which consumes a lot of time and manpower, and it is difficult to maintain consistent operation standards.

[0005] Therefore, there is an urgent need for a wear test tooling to solve the above technical problems. Content of the Utility Model

[0022] Advantages of the present utility model:

[0023] The present utility model provides a wear test tooling, which includes a support platform, a sample fixing rack, a driving member and a pressing block assembly. Among them, the sample fixing rack is used to fix the sample to be tested. The sample fixing rack is movably connected to the support platform and can move relative to the support platform within a plane parallel to the support platform. The pressing block assembly includes a swing arm and a friction block. One end of the swing arm is hinged to the support platform, and the hinge axis is parallel to the support platform. The friction block is fixed to the swing arm. The sample to be tested can be clamped between the friction block and the sample fixing rack. When the sample fixing rack moves relative to the support platform, a frictional force is generated between the friction block and the sample to be tested. The driving member is installed on the support platform and is used to drive the sample fixing rack to move relative to the support platform.

[0024] Specifically, the friction block and the sample fixing rack include a first state and a second state. When in the first state, the friction block abuts against the sample fixing rack. When in the second state, the friction block is away from the sample fixing rack. The friction block switches between the first state and the second state by swinging the swing arm relative to the support platform.

[0025] When loading the sample to be tested, the sample fixing rack and the support platform remain relatively fixed, and the friction block is in the second state. After the installation of the sample to be tested is completed, the swing arm is pulled to switch the friction block from the second state to the first state, and the friction block abuts the sample to be tested against the sample fixing rack. The driving member drives the sample fixing rack to move relative to the support platform, and the friction block is relatively stationary with respect to the support platform. In this way, relative movement occurs between the sample to be tested and the friction block, and a frictional force is generated between the two, and a wear test is performed on the sample to be tested.

[0026] In this way, the wear test tooling can standardize the test method, is convenient to operate, improves the test accuracy, saves labor costs and improves work efficiency. Description of the Drawings

Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0040] As Figures 1 to 3 shown, the present utility model provides a wear test tooling, which includes a support platform 10, a sample fixing rack 20, a driving member, and a pressing block assembly 30. Among them, the sample fixing rack 20 is used to fix the sample to be tested. The sample fixing rack 20 is movably connected to the support platform 10 and can move relative to the support platform 10 within a plane parallel to the support platform 10. The pressing block assembly 30 includes a swing arm 31 and a friction block 32. One end of the swing arm 31 is hinged to the support platform 10, and the hinge axis is parallel to the support platform 10. The friction block 32 is fixed to the swing arm 31. The sample to be tested can be clamped between the friction block 32 and the sample fixing rack 20. When the sample fixing rack 20 moves relative to the support platform 10, a frictional force is generated between the friction block 32 and the sample to be tested. The driving member is installed on the support platform 10 and is used to drive the sample fixing rack 20 to move relative to the support platform 10.

[0041] Specifically, the friction block 32 and the sample fixing rack 20 include a first state and a second state. When in the first state, the friction block 32 abuts against the sample fixing rack 20. When in the second state, the friction block 32 is away from the sample fixing rack 20. The friction block 32 switches between the first state and the second state by swinging the swing arm 31 relative to the support platform 10.

[0042] When loading the sample to be tested, the sample fixing rack 20 and the support platform 10 remain relatively fixed, and the friction block 32 is in the second state. After the installation of the sample to be tested is completed, the swing arm 31 is pulled to make the friction block 32 switch from the second state to the first state, and the friction block 32 abuts the sample to be tested against the sample fixing rack 20. The driving member drives the sample fixing rack 20 to move relative to the support platform 10, and the friction block 32 is relatively stationary with respect to the support platform 10. In this way, relative movement occurs between the sample to be tested and the friction block 32, and a frictional force is generated between the two, and a wear test is performed on the sample to be tested.

[0043] In this way, the wear test tooling can standardize the test method, is convenient to operate, improves the test accuracy, saves labor costs and improves work efficiency.

[0044] Preferably, when the friction block 32 is in the first state, the friction block 32 and the sample to be tested are clamped at 45°.

[0045] Optionally, the pressing block assembly 30 further includes a load member 33, which is mounted at the other end of the swing arm 31. By providing the load member 33, the pressure N applied by the friction block 32 to the sample to be tested is increased, and according to the calculation formula of the friction force F, F=μN, the friction force between the two is increased.

[0046] Optionally, the other end of the swing arm 31 is stepped, including a large diameter section, a small diameter section, and a shoulder formed between the large diameter section and the small diameter section, the small diameter section is located outside the large diameter section, and the load member 33 is sleeved on the small diameter section and can abut against the shoulder. This makes it easy to disassemble and replace the load member 33. Furthermore, the small diameter section is provided with an external thread that can be threadedly connected with a nut, and the nut and the shoulder are located on opposite sides of the load member 33, so that the load member 33 is fixed to the swing arm 31.

[0047] Optionally, the sample fixing frame 20 includes a fixing plate 21 , a pressure strip 22 and a threaded fastener 23 , the sample to be tested is laid on the fixing plate 21 , the pressure strip 22 and the fixing plate 21 clamp part of the sample to be tested, and the pressure strip 22 and the fixing plate 21 are connected by the threaded fastener 23 .

[0048] Specifically, at least two pressure strips 22 are provided, which are respectively located at the edges of the fixing plate 21 on two opposite sides. The clamping force between the pressure strip 22 and the fixing plate 21 is adjusted by screwing the threaded fasteners 23 .

[0049] Optionally, a pulley 24 is installed at the bottom of the sample holder 20, and the pulley 24 is slidably connected to the support platform 10. In this way, the pulley 24 enables the sample holder 20 and the support platform 10 to form sliding friction, thereby reducing friction.

[0050] In this embodiment, the sample fixing frame 20 is rotatably connected to the supporting platform 10 , and the rotation axis is perpendicular to the supporting platform 10 .

[0051] Optionally, a support column 11 is installed at the bottom of the support platform 10, and the axis of the support column 11 is perpendicular to the support platform 10. Preferably, at least three support columns 11 are provided, and at least three of the support columns 11 are not collinear, so that the stability of the support platform 10 is maintained.

[0052] Optionally, a driving member is installed on the side of the support platform 10 facing away from the sample fixing frame 20. In this way, the space at the bottom of the support platform 10 is reasonably used.

[0053] Specifically, the sample holder 20 is rotatably connected to the support platform 10 via a rotating shaft, one end of the rotating shaft fixes the sample holder 20, and the other end penetrates the support platform 10 and is transmission-connected to the output end of the driving member, thus reducing the transmission structure between the sample holder and the driving member.

[0054] Optionally, the driving member is a rotary cylinder 41. Specifically, the rotary cylinder 41 is connected to a solenoid valve 42, and the solenoid valve 42 can control the intake and exhaust of the rotary cylinder 41, thereby switching the forward and reverse rotations of the rotary cylinder 41.

[0055] Optionally, two limit members 12 are fixed to the support platform 10, and the sample fixing frame 20 is located between the two limit members 12. The sample fixing frame 20 can abut against one of the limit members 12 along its swinging direction. In this way, the swinging amplitude of the sample fixing plate 21 relative to the support platform 10 is limited by the limit member 12.

[0056] Furthermore, the wear test tooling further includes a controller 43, and the controller 43 is communicatively connected to the solenoid valve 42 and the driving member. The staff can set through the driving member the swinging amplitude and the number of swings of the driving member driving the sample fixing frame 20.
