Description

Technical Field

[0001] The utility model relates to the technical field of polishing machines, and more particularly to a small steel polishing machine which is convenient for replacing polishing discs. Background Art

[0002] Polishing machines are often used for mechanical grinding, polishing and waxing. Their working principle is: the motor drives the sponge or wool polishing disc installed on the polishing machine to rotate at high speed. Due to the joint action of the polishing disc and the polishing agent and the friction with the surface to be polished, the paint surface pollution, oxide layer and shallow marks can be removed.

[0003] After searching, the utility model patent with announcement number CN219075349U discloses a polishing machine that is convenient for replacing polishing discs, including a housing, wherein a motor is arranged inside the housing, an output end of the motor is fixedly connected to a mounting seat, a slide groove is provided inside the mounting seat, a slider is slidably mounted inside the slide groove, one side of the slider is fixedly mounted with a first spring, and a connecting rod is fixedly mounted on the bottom surface of the slider. By pressing the pressing piece, the push rod is pushed, and then the connecting rod is pushed down, and the blocking block is driven to move down under the action of the connecting rod descending, so that the blocking block is disengaged from the blocking slot, and the polishing disc can be removed, completing the disassembly of the polishing disc. By loosening the pressing piece, the connecting rod is pushed outward under the action of the first spring and the second spring, so that the blocking block enters the blocking slot, fixing the polishing disc, completing the installation of the polishing disc, and no other tools are needed when replacing. The operation is relatively simple, and disassembly and installation are more convenient.

[0004] However, the above patent has the following shortcomings: when in use, the clamping block is driven by the rotating shaft, and the polishing disc encounters resistance during polishing. The polishing disc is driven only by the cooperation between the clamping block and the clamping slot, which affects the connection and transmission quality of the polishing disc. In addition, when the polishing disc is used to polish steel, fine dust is generated, which affects the surrounding working environment. Therefore, we propose a small steel polishing machine that is easy to replace the polishing disc. Utility Model Content

The dust entering the chip storage box 22 is filtered on the filter plate 27. After the polishing is completed, the box door 24 can be opened to clean the dust on the filter plate 27. When the polishing needs to be replaced, the vacuum pump 23 can be started to suck the dust generated by the polishing of the steel from the chip suction cover 26 and the connecting pipe 25 into the interior of the chip storage box 22. The dust entering the chip storage box 22 is filtered on the filter plate 27. After the polishing is completed, the box door 24 can be opened to clean the dust on the filter plate 27. When the polishing disc 20 is removed, the extrusion plate 14 can be pressed to cause the gas rod 10 and the spring 11 to begin to contract. At this time, the clamping block 15 on the extrusion plate 14 is retracted from the clamping groove 19 to the inside of the movable opening 12, and the plug block 8 is lifted upward to be pulled out from the inside of the socket 18, thereby completing the disassembly of the polishing disc 20. When installing, the extrusion plate 14 can be pressed again, and the plug block 8 can be pushed downward into the inside of the socket 18. When the plug block 8 enters the inside of the socket 18, the pressure on the extrusion plate 14 can be released, and the elastic force of the spring 11 and the gas rod 10 can be used to drive the extrusion plate 14 to reset, so that the clamping block 15 on the extrusion plate 14 is clamped into the inside of the clamping groove 19, thereby realizing the installation of the polishing disc 20.
