When working, the device is first fixed in a specified position. When the brake pad needs to be tested, the friction wheel 114 needs to be fixed to the side wall of the clamping block 112. When encountering large friction When the friction wheel 114 is rubbed, the first adjusting nut 113 is turned to loosen it, and then the clamping block 112 is pulled out to a suitable position and the first adjusting nut 113 is turned again to tighten it in the chuck 111. At the same time, when a smaller friction wheel 114 is encountered, the first adjusting nut 113 is turned to loosen it, and then the clamping block 112 is pushed into the chuck 111 and the first adjusting nut 113 is turned again to rotate and fix it. When encountering friction wheels 114 of different sizes, it can be adjusted according to needs. After fixing the friction wheel 114, the motor 15 is started. After starting, the motor 15 drives the first rotating shaft 16 to rotate, and the first rotating shaft 16 After rotating, it drives the first pulley 17 to rotate and then drives the belt 18 to rotate. After the belt 18 rotates, it drives the second pulley 19 to rotate. At the same time, when the second pulley 19 rotates, the second rotating shaft 110 rotates. After the second rotating shaft 110 rotates, it drives the chuck 111 to rotate and then drives the friction wheel 114 to rotate to grind the brake pads that need to be tested. By grinding the brake pads, the status and wear resistance of the brake pads can be observed to distinguish whether they can be used. Through the above structure, it is convenient for users to adjust and fix brake pads of different sizes, and the status of the brake pads can be observed through grinding.

[0026] like Figures 1 to 3As shown, the top surface of the desktop 1 is fixedly connected to a second fixed block 2; the side wall of the second fixed block 2 is fixedly connected to a first guide rod 21; the side wall of the second fixed block 2 is rotatably connected to a first screw rod 22; one end of the first guide rod 21 is fixedly connected to an adjuster 23; the first screw rod 22 is slidably connected to a first workbench 24; the top surface of the first workbench 24 is fixedly connected to a bolt 25; the side wall of the bolt 25 is fixedly connected to a first spring 26; the top of the first spring 26 is fixedly connected to a pressure plate 27. During operation, after the friction wheel 114 is fixed, the brake pad to be tested can be placed on the side end of the first workbench 24, and then the bolt 25 is rotated to make the bolt 25 aligned with the first workbench 24. The pressure plate 27 applies pressure to press the pressure plate 27 onto the brake pad to be tested, so that the brake pad is pressed and fixed. At the same time, when the pressure plate 27 is pressed, the first spring 26 can play a supporting and buffering role and will not cause the pressure plate 27 to drop quickly. When the first workbench 24 needs to be moved horizontally, the adjuster 23 can be rotated. The adjuster 23 will drive the first screw rod 22 to rotate so that the first workbench 24 moves on the first screw rod 22. At the same time, the first guide rod 21 causes the first workbench 24 to move back and forth horizontally. Different positions can be adjusted by rotating the adjuster 23 for easy testing. Through the above structure, the clamping and fixing of the brake pad is improved, making testing more convenient, and it is also convenient to adjust different positions during testing.

The brake pad is placed on the top surface of the placement table 46, and then the third adjusting nut 42 is rotated. The third adjusting nut 42 drives the second screw rod 41 to rotate. After the second screw rod 41 is rotated, the sliding block 44 slides up and down on the second screw rod 41 and also drives the pointer 45 to move. When testing is needed, it will slide downward so that the pointer 45 contacts the brake pad and then the end of the pointer 45 points to the scale 47, and then the thickness of the brake pad can be known. The degree of wear of the brake pad can be known by detecting the thickness of the brake pad. Through the above structure, users can quickly know the thickness of the brake pad, which improves the efficiency of measuring the brake pad.

[0029] like Figure 1 As shown, a storage box 5 is fixedly connected to the top surface of the desktop 1; a placement groove 51 is opened inside the storage box 5; a box cover 52 is provided on the top surface of the storage box 5. During operation, when the brake pads after testing are placed on the top surface of the desktop 1, too many brake pads will make the top surface of the desktop 1 messy. At this time, the box cover 52 is opened and the brake pads are placed in the placement groove 51 inside the storage box 5 to reduce the mess on the top surface of the desktop 1. Through the above structure, the mess on the top surface of the desktop 1 caused by too many brake pads is reduced.

When working, when the device is placed in different locations, the device may be too high or too low due to different placement areas. When the device is too high, the button 61 can be pressed, and the button 61 will squeeze the second spring 62 to retract the button 61 into the table leg 11, and then the table leg 11 is pressed downward to make the device descend. At the same time, when the device is too low, the button 61 can be pressed, and the button 61 will squeeze the second spring 62 to retract the button 61 into the table leg 11, and then the table leg 11 is pushed upward to make the device rise. The lifting and lowering can be adjusted according to needs. Through the above structure, the device can be raised and lowered when it is too high or too low.

[0031] like Figures 1 to 4As shown, the bottom surface of the lifting leg 6 is fixedly connected to an anti-slip pad 7; the anti-slip pad 7 is made of flexible material. When working, the anti-slip pad 7 can reduce the slipping of the device during operation, which may cause damage to the device. Through the above structure, the device can be effectively avoided from slipping during operation.

[0032] When working, first fix the device in the specified position. When the brake pad needs to be tested, the friction wheel 114 needs to be fixed to the side wall of the clamping block 112. When encountering a larger friction wheel 114, turn the first adjusting nut 113 to loosen it, then pull the clamping block 112 out to a suitable position and turn the first adjusting nut 113 again to tighten it in the chuck 111. At the same time, when encountering a smaller friction wheel 114, turn the first adjusting nut 113 to loosen it, then push the clamping block 112 into the chuck 111 and turn the first adjusting nut 113 again to rotate and fix it. When encountering friction wheels 114 of different sizes, they can be adjusted according to needs. After fixing the friction wheel 114, start the motor 15. After starting, the motor 15 drives the first rotating shaft 16 to rotate. The first rotating shaft After 16 rotates, it drives the first pulley 17 to rotate and then drives the belt 18 to rotate. After the belt 18 rotates, it drives the second pulley 19 to rotate. At the same time, when the second pulley 19 rotates, the second rotating shaft 110 rotates. After the second rotating shaft 110 rotates, it drives the chuck 111 to rotate and then drives the friction wheel 114 to rotate to grind the brake pad that needs to be tested. By grinding the brake pad, the state and wear resistance of the brake pad can be observed to distinguish whether it can be used. Through the above structure, it is convenient for the user to adjust and fix brake pads of different sizes. The state of the brake pad can be observed by grinding. When the friction wheel 114 is fixed, the brake pad to be tested can be placed on the side end of the first workbench 24 and then the bolt 25 is rotated to make the bolt 25 Apply pressure to the pressure plate 27, press the pressure plate 27 onto the brake pad to be tested, so that the brake pad is pressed and fixed. At the same time, when the pressure plate 27 is pressed, the first spring 26 can play a supporting and buffering role and will not cause the pressure plate 27 to drop quickly. When it is necessary to move the first workbench 24 horizontally, the adjuster 23 can be rotated. The adjuster 23 will drive the first screw rod 22 to rotate so that the first workbench 24 moves on the first screw rod 22. At the same time, the first guide rod 21 enables the first workbench 24 to move back and forth horizontally. Different positions can be adjusted by rotating the adjuster 23 for easy testing. Through the above structure, the clamping and fixing of the brake pad is improved, making testing more convenient. At the same time, it is convenient to adjust different positions during testing. When the brake pad is fixed on the first workbench 24 When encountering brake pads of different sizes that cannot be adjusted and fixed, resulting in the brake pad becoming loose, the second adjusting nut 3 is turned at this time. After the second adjusting nut 3 is turned, the connecting column 31 is driven to rotate, and then the gear 32 is driven to rotate. When the gear 32 rotates, the rack 33 is driven up and down by the gear 32. When encountering a smaller brake pad, the top plate 34 can be moved upward by turning the second adjusting nut 3. When encountering a larger brake pad, the second adjusting nut 3 can be turned in the opposite direction. It can be adjusted according to needs. The above structure effectively avoids the loosening of brake pads of different sizes. When the thickness of the brake pad needs to be tested, the brake pad can be placed on the top surface of the placement table 46, and then the third adjusting nut 42 is turned.The third adjusting nut 42 drives the second screw rod 41 to rotate. After the second screw rod 41 rotates, the sliding block 44 slides up and down on the second screw rod 41 and also drives the pointer 45 to move. When testing is needed, it will slide downward to make the pointer 45 contact the brake pad. Then the end of the pointer 45 points to the scale 47, and the thickness of the brake pad can be known. By detecting the thickness of the brake pad, the degree of wear of the brake pad can be known. Through the above structure, it is convenient for users to quickly know the thickness of the brake pad and improve the efficiency of measuring the brake pad. When the brake pads are placed on the top surface of the desktop 1 after testing, too many brake pads will make the top surface of the desktop 1 messy. At this time, the box cover 52 is opened and the brake pads are placed in the placement groove 51 inside the storage box 5 to reduce the mess on the top surface of the desktop 1. Through the above structure, the mess on the top surface of the desktop 1 caused by excessive placement of brake pads is reduced. When the device is placed in different locations, the device may be too high or too low due to different placement areas. When the device is too high, the button 61 can be pressed. The button 61 will squeeze the second spring 62 to retract the button 61 into the table leg 11. Then, the table leg 11 can be pressed downward to lower the device. At the same time, when the device is too low, the button 61 can be pressed. The button 61 will squeeze the second spring 62 to retract the button 61 into the table leg 11. Then, the table leg 11 can be pushed upward to raise the device. The lifting and lowering can be adjusted according to needs. The above structure facilitates the lifting and lowering of the device when it is too high or too low. The anti-slip pad 7 can reduce the slipping of the device during operation, which may cause damage to the device. The above structure effectively avoids the slipping of the device during operation.
