Description

Technical Field

[0001] This utility model relates to the field of polishing and grinding tools, specifically a polishing machine. Background Technology

[0002] Polishing machines are common polishing equipment on the market, mainly used in machinery manufacturing, car detailing and building decoration. They are mainly used to reduce the surface roughness of workpieces to obtain a bright and smooth surface. The most common polishing machines on the market are handheld, which are convenient to carry and flexible in operation. Handheld polishing machines mainly have two power supply structures: charging cable connection and battery pack connection.

[0003] Patent document CN215394429U discloses a DC mini polishing machine, comprising a power cord, a body, and a polishing head assembly. The polishing head assembly includes a polishing head housing, a polishing shaft, and a rotating shaft, with a sector gear connected to one end of each shaft. The polishing shaft rotates via a connection between the two sector gears. The front end of the motor inside the machine is directly connected to a planetary gearbox, and it is equipped with a shaft lock switch and a segmented speed control knob. This is a DC mini polishing machine with a simple structure, convenient portability and operation, and good safety and versatility. A DC mini polishing machine, comprising a power cord, a body, and a polishing head assembly, is characterized by: a polishing head assembly connected to the front end of the body and a power cord connected to the rear end; the polishing head assembly includes a polishing head housing, a polishing shaft, and a rotating shaft; bearings are connected to the outer sides of both ends of the rotating shaft; and a sector gear is connected to the front end of the rotating shaft. However, the existing technology still has shortcomings:

[0004] In the existing technology, the machine body and polishing head assembly are designed as a single unit, which is not convenient for disassembly. Since the planetary gearbox inside the machine body is prone to damage after long-term use, and the polishing machine in the above-mentioned technical solution is not convenient for disassembling and replacing the planetary gearbox, a new polishing machine can only be replaced, which increases the cost of use, reduces the service life of the polishing machine, reduces work efficiency, and is inconvenient for people to use.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.
