Description

Technical Field

[0001] This utility model relates to the technical field of brush replacement equipment, specifically to a quick-change mechanism for high-speed rotation drive of brushes. Background Technology

[0002] When deburring the main oil hole, the brush will experience some wear. If the brush is severely damaged, it should be replaced in time to avoid affecting the normal use of the equipment and ensure work efficiency. However, commonly used brushes are usually integrated with the brush handle, requiring the brush handle and brush to be replaced as a whole, which is complicated and inconvenient to disassemble. On the other hand, when assembling a separate brush and brush handle, the connection between the brush and brush handle cannot be guaranteed to be firm, which may cause the brush to be unable to achieve precise deburring during the deburring process, thus affecting the deburring effect.

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] A quick-change mechanism for high-speed rotation drive of brushes, such as Figures 1 to 4 As shown, it includes a brush 1 and a brush rod 2. The lower end of the brush 1 is provided with a connecting rod 6 that is inserted and connected to the upper center of the brush rod 2. A limiting sleeve 3 is sleeved on the outer side of the connecting rod 6, and the lower part of the limiting sleeve 3 is sleeved on the outer peripheral side wall of the brush rod 2 connected to the connecting rod 6.

[0017] The upper part of the connecting rod 6 is provided with a limiting component that works with the limiting sleeve 3 to limit the brush 1, and the lower part of the connecting rod 6 is provided with a clamping component that works with the limiting sleeve 3 to lock the brush 1 and the brush rod 2.

[0018] The limiting component includes a limiting block 4 and a compression spring 5. The upper part of the connecting rod 6 has a through slot 7 for installing the limiting block 4 and the compression spring 5. The through slot 7 is horizontally set perpendicular to the vertical axis of the connecting rod 6.

[0019] One end of the compression spring 5 is connected to the limiting block 4, and the other end is connected to the inner wall of one end of the through slot 7.

[0020] A limiting protrusion 10 is provided at one end of the limiting block 4 away from the compression spring 5, and a limiting hole 9 is provided on the upper part of the limiting sleeve 3 to connect with the limiting protrusion 10.

[0021] When the limiting sleeve 3 is fitted onto the connecting rod 6, as the limiting sleeve 3 moves, the limiting protrusion 10 on the limiting block 4 inside the through slot 7 extends into the limiting hole 9 on the limiting sleeve 3 to limit the brush 1.

[0022] The clamping assembly includes a pin connecting the brush rod 2 and the connecting rod 6. The lower part of the connecting rod 6 has a positioning hole 8 for connecting with the pin, and the upper part of the brush rod 2 has a corresponding pin hole for connecting with the pin. After the connecting rod 6 and the brush rod 2 are connected by the pin, the pin is also tightened by a limiting sleeve 3 on the outer wall of the brush rod 2 to limit the pin and prevent it from coming out.

[0023] When it is necessary to replace brush 1, press the limiting protrusion 10 in the limiting hole 9 to disengage the limiting protrusion 10 from the limiting hole. At the same time, move the limiting sleeve 3 upward to expose the pin shaft. Move the pin shaft out and move the limiting sleeve 3 and brush 1 upward to remove brush 1. Then remove the limiting sleeve 3 and remove the damaged brush 1.

[0024] Then take out the new brush 1, install the compression spring 5 and the limiting block 4 in the through slot 7, then put the limiting sleeve 3 on the lower end of the brush 1 and move it upward so that the limiting sleeve 3 restricts the limiting block 4 and the compression spring 5 in the through slot 7, while exposing the position of the positioning hole 8. Insert the connecting rod 6 into the center hole at the top of the brush rod 2 so that the positioning hole 8 and the pin hole are aligned. Pass the pin through the positioning hole 8 and the pin hole. Then, move the limiting sleeve 3 downward to cover the pin and prevent the pin from coming out.

[0025] Finally, adjust the position of the limiting sleeve 3 so that the upper limiting hole 9 is aligned with the limiting protrusion 10 on the limiting block 4, so that the limiting protrusion 10 extends into the limiting hole 9 to limit the brush 1 and prevent the brush 1 from moving up and down, thus completing the replacement of the new brush.

[0026] This utility model provides a quick-change mechanism for high-speed rotation drive of a brush. By setting a limiting component and a clamping component in cooperation with the limiting sleeve, the brush and brush rod can be quickly assembled. The structure is simple and easy to assemble. The clamping component and the limiting sleeve securely connect the brush and the brush rod. At the same time, the limiting component and the limiting sleeve limit the brush and prevent the brush from moving up and down, ensuring the stability of the connection between the brush and the brush rod and realizing quick brush replacement.
