Description

Technical Field

[0001] The utility model relates to the technical field of metal polishing, in particular to a pressing mechanism and a metal polishing machine. Background Art

[0002] Polishing machines are also called grinders and are often used for mechanical grinding, polishing and waxing. The 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 combined effect 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] Chinese patent publication number CN218534053U discloses a polishing machine for metal product production, which uses a cover to cover the rotating motor and the top part of the polishing wheel, and then uses a vacuum cleaner to absorb air to form a negative pressure in the cover, so as to collect the polished metal debris under negative pressure to prevent the metal debris from being blown into the air and entering the mouth and nose of people. At the same time, the material box conveys the coolant to the outlet pipe through a soft water pipe, and then discharges it from the end of the outlet pipe to cool the rotating polishing wheel, thereby increasing the service life of the polishing wheel. At the same time, the coolant can reduce the dust of the metal debris generated by polishing, further avoiding the spread of the metal debris.

[0004] However, the above patent has the following shortcomings:

[0005] The polishing machine does not restrict the position of the metal product. When the polishing wheel just contacts the metal product, the metal product is prone to vibrate and move under the action of the polishing wheel, thereby reducing the polishing accuracy. Utility Model Content
