[0002] A dynamic balancing machine is a type of balancing machine used to measure the magnitude and location of imbalance in a rotating object (rotor). The main performance indicators of a dynamic balancing machine are the minimum achievable residual imbalance and the reduction rate. The former is the minimum residual imbalance the balancing machine can achieve, measuring the machine's maximum balancing capability; the latter is the ratio of the reduction in imbalance after one correction to the initial imbalance.

[0003] The brake pads of existing dynamic balancing machine brake devices are prone to wear and tear under long-term working conditions. Their structural design makes the disassembly and replacement of individual components cumbersome and maintenance inconvenient. At the same time, the device is not equipped with a moving rod length adjustment mechanism that can adapt to diverse needs, which cannot flexibly meet the usage requirements of different scenarios, thus restricting the adaptability and practical efficiency of the equipment.

[0017] Specifically, the brake pad 6 is rotatably connected to the rectangular block 22, and triangular support plates are welded and fixed on both sides between the mounting bracket 21 and the moving rod 7. By adopting the above technical solution, the brake pad 6 can rotate on the rectangular block 22 after installation, and the triangular support plates make the mounting bracket 21 and the moving rod 7 more secure.

[0018] Specifically, after the rectangular block 22 is installed into the rectangular groove 23, the side of the rectangular block 22 fits tightly against the inner wall of the rectangular groove 23. The mounting bracket 21 has through holes at both ends corresponding to the mounting bolts 26. By adopting the above technical solution, the rectangular block 22 is more stable in the rectangular groove 23 after it is installed into the rectangular groove 23. The mounting bolts 26 can be inserted into the mounting bracket 21 and screwed into the mounting holes 27 on the side of the protrusion 24.

[0019] Specifically, after the brake pad 6 is installed into the mounting bracket 21, the lower end of the brake pad 6 is lower than the lower end of the mounting bracket 21. The mounting bracket 21 and the moving rod 7, as well as the protrusion 24 and the rectangular block 22 are fixed by welding. By adopting the above technical solution, the lower end of the mounting bracket 21 is prevented from protruding and affecting the use of the brake pad 6.

[0020] In this embodiment, when the lever 5 is pressed, the moving rod 7 rotates on the fixed frame 1, the locking spring 8 is compressed, and the brake pad 6 contacts the workpiece to play a braking role. After the lever 5 is released, the locking spring 8 extends and pushes the moving rod 7 to reset, and the brake pad 6 returns to its original position and does not contact the workpiece.

[0021] When installing the brake pad 6, the rectangular blocks 22 at both ends of the brake pad 6 are installed into the rectangular grooves 23 on the lower side of both ends of the mounting bracket 21. The protrusions 24 at both ends of the rectangular blocks 22 are inserted into the grooves 25. Then, the mounting bolts 26 are inserted into the mounting bracket 21 and screwed into the mounting holes 27 on the side of the protrusions 24 to fix the protrusions 24, the rectangular blocks 22 and the brake pad 6.

By adopting the above technical solution, pulling the grip 5 causes the adjustment rod 31 to slide in the sliding cavity 32 of the moving rod 7. After the grip 5 and the moving rod 7 are adjusted to a suitable distance, the fixing bolts 35 are screwed into the fixing holes 36 corresponding to the front end of the adjustment rod 31 to fix the adjustment rod 31. The adjustment component 3 can adjust the length of the moving rod 7 according to the requirements, improving the adaptability of the device.

[0023] Specifically, the adjustment assembly 3 also includes a limiting block 33. The limiting block 33 is fixed to one side of the adjustment rod 31, and a groove 34 corresponding to the limiting block 33 is opened at one end of the sliding cavity 32. By adopting the above technical solution, when the adjustment rod 31 moves in the sliding cavity 32, the limiting block 33 at one end of the adjustment rod 31 slides in the groove 34. The limiting block 33 and the groove 34 can limit the adjustment rod 31 and prevent the adjustment rod 31 from sliding out of the sliding cavity 32.

[0024] Specifically, a through hole corresponding to the fixing bolt 35 is provided on one side of the front end of the moving rod 7, and the side of the adjusting rod 31 is tightly fitted with the inner wall of the sliding cavity 32.

[0025] In this embodiment, when the grip 5 is pulled, the adjusting rod 31 slides in the sliding cavity 32 of the moving rod 7. After the grip 5 and the moving rod 7 are adjusted to a suitable distance, the fixing bolt 35 is screwed into the fixing hole 36 corresponding to the front end of the adjusting rod 31 to fix the adjusting rod 31. The adjusting component 3 can adjust the length of the moving rod 7 as needed, improving the adaptability of the device.

[0026] When the adjusting rod 31 moves in the sliding cavity 32, the limiting block 33 at one end of the adjusting rod 31 slides in the sliding groove 34. The limiting block 33 and the sliding groove 34 can limit the adjusting rod 31 and prevent the adjusting rod 31 from sliding out of the sliding cavity 32.

[0028] When installing the brake pad 6, the rectangular blocks 22 at both ends of the brake pad 6 are installed into the rectangular grooves 23 on the lower side of both ends of the mounting bracket 21. The protrusions 24 at both ends of the rectangular blocks 22 are inserted into the grooves 25. Then, the mounting bolts 26 are inserted into the mounting bracket 21 and screwed into the mounting holes 27 on the side of the protrusions 24 to fix the protrusions 24, the rectangular blocks 22 and the brake pad 6. The brake pad 6 can rotate on the rectangular blocks 22. The mounting assembly 2 allows the brake pad 6 to be disassembled and replaced separately, avoiding the need to replace the entire device due to severe wear of the brake pad 6 after long-term use.

[0029] Pulling the handle 5 causes the adjusting rod 31 to slide in the sliding cavity 32 of the moving rod 7. After the handle 5 and the moving rod 7 are adjusted to a suitable distance, the fixing bolt 35 is screwed into the fixing hole 36 corresponding to the front end of the adjusting rod 31 to fix the adjusting rod 31. The adjusting component 3 can adjust the length of the moving rod 7 as needed, improving the adaptability of the device.

[0030] When the adjusting rod 31 moves in the sliding cavity 32, the limiting block 33 at one end of the adjusting rod 31 slides in the sliding groove 34. The limiting block 33 and the sliding groove 34 can limit the adjusting rod 31 and prevent the adjusting rod 31 from sliding out of the sliding cavity 32.
