The use method of the special acrylic dustproof polishing machine specifically comprises the following steps:

the method comprises the following steps: placing a fixed shell 17 between two U-shaped clamping blocks 16, rotating a rotating handle 15, rotating the rotating handle 15 to drive a threaded column 13 to rotate, rotating the threaded column 13 to drive the two U-shaped clamping blocks 16 to relatively slide in a sliding groove at the bottom of a fixed seat 12, further driving the two U-shaped clamping blocks 16 to be inserted into slots 18 at two sides of the fixed shell 17, and locking the U-shaped clamping blocks 16 in the slots 18 through fixing bolts to complete the fixation of the fixed shell 17;

step two: starting a vertical moving motor, driving a second lead screw 902 to rotate by an output shaft of the vertical moving motor, driving a horizontal moving track 801 on a second moving block to vertically move by the rotation of the second lead screw 902, starting a horizontal moving motor 804, driving a first lead screw 803 to rotate by an output shaft of the horizontal moving motor 804, driving a lifting cylinder 20 on the first moving block to horizontally move by the rotation of the first lead screw 803, starting the lifting cylinder 20, driving a fixed seat 12 to downwards move by a piston rod of the lifting cylinder 20, and further adjusting the polishing position of a polishing disc 7;

step three: starting a driving motor 11, driving an output shaft of the driving motor 11 to drive a driving bevel gear 1101 to rotate, wherein the driving bevel gear 1101 is meshed with a driven bevel gear 301 to drive a rotating shaft 3 to rotate, the rotating shaft 3 drives a fixed sleeve 401 to rotate through a coupler 5, the fixed sleeve 401 rotates to drive a knuckle bearing 403 in a fixed groove 402 to rotate, and then the rotating shaft 406 is driven to rotate, the rotating shaft 406 rotates to drive a polishing disc 7 at the end part of the rotating shaft 406 to rotate, and the polishing disc 7 polishes the surface of a workpiece;

step four: when the polishing disk 7 contacts with the surface of an uneven workpiece, the polishing disk 7 is pressed by the surface of the workpiece, when the pressure is greater than the elastic force of the telescopic spring 409, the rotating shaft 406 drives the telescopic ring 407 to move to one side to press the telescopic spring 409, and under the action of the joint bearing 403, universal floating of the rotating shaft 406 and self-adjustment of the polishing disk 7 are realized.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "left", "right", and the like, indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, are only for convenience in describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation and a specific orientation configuration and operation, and thus, should not be construed as limiting the present invention. Furthermore, "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and the like are to be construed broadly and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be directly connected or indirectly connected through an intermediate member, or they may be connected through two or more elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
