[0035] Example 1

[0036] A sole wear resistance testing device includes a workbench 11, a mounting frame 1, and a polishing assembly, wherein the mounting frame 1 is arranged on the upper end surface of the workbench 11, and the polishing assembly is mounted on the mounting frame 1; and further includes a fixing assembly, wherein the fixing assembly includes a supporting mechanism and a positioning mechanism;

[0037] The support mechanism is installed on the workbench 11, and the support mechanism includes a support seat 16, a support rod 24 and a spring 25. The support seat 16 is provided with a vertical movable hole 27, the lower end of the support rod 24 is movably installed in the movable hole 27, the upper end of the support rod 24 is provided with a limit ring 26, and the spring 25 is sleeved on the support rod 24. The lower end of the spring 25 abuts against the upper end surface of the support seat 16, and the upper end of the spring 25 abuts against the limit ring 26;

[0038] The positioning mechanism is arranged at the upper end of the supporting mechanism, and is used to fix and position the shoes.

[0039] In the above scheme, by setting up a support mechanism, during the test, the fixed component moves downward, pressing down on the sole, so that spring 1 is in a compressed state. Spring 1 in the support mechanism can provide elastic force. The elastic force of spring 1 makes the sole close to the grinding wheel during the test, ensuring the normal progress of the test.

[0040] In this embodiment, specifically, the polishing assembly includes a polishing mechanism and a lifting mechanism, the lifting mechanism is mounted on a mounting frame 1, the polishing mechanism is mounted on the lifting mechanism, and the lifting mechanism drives the polishing mechanism to move up and down. Further, the lifting mechanism includes a stepping motor 2, a screw rod 3, and two guide rods 4, the stepping motor 2 is mounted on the upper end of the mounting frame 1, the screw rod 3 is transmission-connected to the stepping motor 2, and the polishing mechanism is provided with a threaded hole that cooperates with the screw rod 3 and a guide hole that cooperates with the guide rod 4. Furthermore, the polishing mechanism includes a drive motor 6, a mounting seat 5, and a polishing wheel 7, the drive motor 6 is mounted on the mounting seat 5, the polishing wheel 7 is transmission-connected to the output shaft of the drive motor 6, and the drive motor 6 drives the polishing wheel 7 to rotate to rub the sole.

[0041] In the above scheme, the mounting seat is driven downward by the forward rotation of the stepper motor, the grinding wheel on the mounting seat contacts the sole and compresses spring 1, and then the drive motor is turned on to drive the grinding wheel to rotate for wear resistance testing. After the test is completed, the stepper motor is reversed to drive the mounting seat upward.

[0042] In this embodiment, the positioning mechanism includes a positioning seat 9, a top block 10 and two side push rods 8. The top block 10 is movably mounted on the positioning seat 9, and the two side push rods 8 are movably mounted on both sides of the positioning seat 9. When the top block 10 moves toward the positioning seat 9, it drives the two side push rods 8 to be ejected toward both sides of the positioning seat 9. Specifically, two movable rods 13 are provided on one side of the top block 10, and movable holes 27 cooperating with the movable rods 13 are provided on the positioning seat 9. A cross bar 14 is provided at one end of the two movable rods 13 away from the top block 10, and a movable cavity 15 cooperating with the cross bar 14 is provided in the positioning seat 9. A spring 2 12 is sleeved on the movable rod 13, and one end of the spring 2 12 abuts against the upper end face of the positioning seat 9, and the other end abuts against the lower end face of the top block 10. Further, as Figure 3 and Figure 4 As shown, a driving rod 19 is provided on the crossbar 14, and a driving hole 17 cooperating with the driving rod 19 is provided on the positioning seat 9. When the driving rod 19 moves in the driving hole 17, it drives the two movable rods 13 to move. Furthermore, a driving groove 18 is provided on the driving rod 19, and a driving rack 20 is provided on the side of the driving groove 18. A driving gear 28 meshing with the two driving racks 20 is provided in the driving hole 17. Two matching holes 29 cooperating with the side push rod 8 are provided on the positioning seat 9, and the matching holes are perpendicular to the driving hole 17. A driving groove 22 is provided on the side push rod 8, and a driving rack 21 is provided on the side of the driving groove 22. The driving racks 21 on the two side push rods 8 are respectively meshed with the two driving gears 28 for transmission. It should be noted that, as Figure 4 As shown, the second driving rack on the upper side push rod is arranged on the upper side of the driving groove 2, and the second driving rack on the lower side push rod is arranged on the lower side of the driving groove 2.

[0043] Among them, in order to enable the two side push rods to retract normally after the test is completed, a spring three 23 is arranged in the matching hole, one end of the spring three 23 is connected to the bottom of the matching hole 29, and the other end is connected to the side push rod 8.

[0044] In the above scheme, if Figure 3 and 4As shown in , when the shoe is put on the positioning mechanism, the top block is located at the toe of the shoe, and the grinding wheel rotates. Under the action of friction, the shoe drives the top block to move in the direction of compression of spring 2. During the movement of the top block, the driving rod is driven downward, and the driving rack 1 on the driving rod drives the two driving gears to rotate clockwise. The driving gear drives the upper side top rod to push out to the right and the lower top rod to push out to the left to hold the two sides of the shoe inside to prevent the shoe from shaking left and right. At the same time, the front and back positioning of the shoe is achieved through the friction of the grinding wheel. This solution is achieved through the friction of the grinding wheel. Now let's position the shoes. When the wear resistance test is completed, the grinding wheel stops rotating and disengages from the sole. The two side push rods retract toward the center of the positioning seat under the action of the elastic force of spring two and spring three, and disengage from the two sides inside the shoe. The shoe can be taken out from the positioning mechanism, and the positioning and removal of the shoe are convenient. In the above scheme, the force of spring one in the support mechanism allows the grinding wheel and the sole to be in close contact during the test. Therefore, the grinding wheel can continuously provide a large friction force to the sole of the shoe, and the friction force is used to achieve continuous positioning of the shoe.

[0045] Example 2

[0046] This embodiment discloses a testing method using a sole wear resistance testing device, the method comprising the following steps:

[0047] Place the shoes to be tested on the positioning assembly on the workbench 11;

[0048] Turn on the stepper motor 2, which rotates forward to drive the screw rod 3 to rotate and drive the mounting base 5 to move downward until the grinding wheel 7 contacts the sole and the spring 1 25 is in a compressed state;

[0049] Turn on the drive motor 6, which drives the grinding wheel 7 to rotate counterclockwise to rub the surface of the sole;

[0050] After the set time is reached, the drive motor 6 is turned off, and then the stepper motor 2 is turned on. The stepper motor 2 reverses to drive the screw rod 3 to rotate and drive the mounting seat 5 to move online, and the grinding wheel 7 is separated from the sole;
