Technical Field

[0001] The utility model relates to the field of polishing machines, in particular to a novel cloth wheel polishing machine. Background Art

[0002] A polishing machine is a device that drives a cloth wheel to rotate so that the cloth wheel rubs against the surface of a workpiece to achieve the purpose of grinding and polishing. Existing cloth wheel polishing machines, such as CN219152474U, are a polishing machine that is easy to disassemble and assemble a cloth wheel, comprising a frame, a first bearing seat and a second bearing seat rotating shaft are respectively provided on both sides of the frame, the cloth wheel is mounted on the rotating shaft, and the two ends of the rotating shaft are respectively rotatably arranged on the first bearing seat and the second bearing seat; the first bearing seat comprises two splicing seats, the two splicing seats are rotatably connected to the frame, and the splicing seat has a notch arranged in a semicircular shape, the two splicing seats abut against each other to form a bearing hole between the two notches, and one end of the rotating shaft is rotatably arranged in the bearing hole.

[0003] When the above-mentioned cloth wheel polishing machine is in use, the distance between the adjustment plate and the bottom plate can be adjusted by rotating the adjustment bolt, and then the height of the adjustment plate can be adjusted to achieve height adjustment of the drive motor, that is, the tightness of the belt can be adjusted. When the belt is loose, the height of the drive motor can be lowered, the distance between the drive motor and the rotating shaft can be increased, and then the belt can be tightened. After replacing the new belt, the drive motor can also be adjusted to the corresponding height to tighten the belt. This operation is cumbersome, and adjusting the height of the drive motor will make the drive motor structure unstable. For this reason, we propose a new cloth wheel polishing machine.
