[0044] It can be understood that the polishing machine in the embodiment is in a closed state during the polishing process, and the cleaning mechanism in the roller 20 starts to adsorb and collect metal powder generated during the polishing process; the workpiece is fixed by the fixed clamp 24 inside the roller 20, and the roller 20 rotates according to the set parameters (such as rotation speed, time and rotation direction) to make the workpiece fully contact with the abrasive, and the polishing operation is completed; after the polishing is completed, the material door 22 is opened, and the cleaning mechanism collects the metal powder for centralized treatment, and the operator can conveniently clean the collected powder for the next polishing operation. The embodiment realizes the automatic cleaning function during the polishing process, reduces the manual intervention, and reduces the labor intensity; and the embodiment can collect the metal powder in time during the polishing process, avoid the damage of the powder accumulation to the surface quality of the workpiece and the equipment, and improve the cleaning efficiency.

[0045] In some embodiments, the cleaning mechanism comprises a first magnetic attraction piece 30, which is arranged on the side of the material door 22 facing the polishing cavity 25 when the material door 22 is in a closed state.

[0046] In the embodiment, the first magnetic attraction piece 30 is arranged on the side of the material door 22 facing the polishing cavity 25 when the material door 22 is in a closed state, and the magnetic field generated by the first magnetic attraction piece 30 can adsorb the metal powder generated during the polishing process, so as to effectively collect the metal powder.

[0047] In some embodiments, the barrel wall of the roller 20 is provided with a containing groove 23, and the containing groove 23 is in communication with the material port 21; a sliding rail is arranged inside the containing groove 23 extending from the material port 21, and the two sides of the material door 22 are respectively slidingly connected to the two sliding rails; the material door 22 can slide along the sliding rails to the material port 21 or the containing groove 23, so that the material door 22 slides to a closed state or an open state; the cleaning mechanism comprises a collecting assembly, and the collecting assembly comprises a collecting box 31 and a scraping plate 32; the collecting box 31 is arranged on the side of the material door 22 facing the polishing cavity 25 when the material door 22 is in an open state, the opening of the collecting box 31 faces the material door 22 in the open state, and the projection of the material door 22 in the open state completely falls into the range of the opening of the collecting box 31; the scraping plate 32 is arranged at the opening of the collecting box 31, and the scraping side of the scraping plate 32 extends to the sliding path of the material door 22; during the process that the material door 22 slides to the open state, the first magnetic attraction piece 30 slides with the material door 22 and abuts against the scraping side of the scraping plate 32, so that the metal powder adsorbed by the first magnetic attraction piece 30 is scraped into the collecting box 31.

During the process that the material door 22 is translated to open, the material door 22 drives the first magnetic attraction piece 30 to move and abut against the scraping side of the scraping plate 32, so that the adsorbed metal powder is scraped into the collecting box 31.

[0049] Specifically, during the polishing process, the material door 22 is in a closed state, and the cleaning mechanism starts to adsorb and collect the metal powder in the polishing cavity 25. The workpiece is fixed by the fixed clamp 24 inside the roller 20, and the roller 20 rotates according to the set parameters to make the workpiece fully contact with the abrasive to complete the polishing operation. After the polishing is completed, the material door 22 is opened along the sliding rail, and in the process of the translation of the material door 22, the first magnetic attraction piece 30 in the cleaning mechanism is moved and in contact with the material scraping plate 32, and the metal powder is scraped into the collection box 31. Through the cooperation of the translation of the material door 22 and the material scraping plate 32, the metal powder generated during the polishing process can be collected in time and completely, avoiding the damage to the surface quality of the workpiece and the equipment caused by the accumulation of the powder, and the cleaning efficiency is significantly improved.

[0050] In some embodiments, two long grooves are arranged on both sides of the accommodating groove 23, the collection assembly further comprises a connecting rod 33 and an elastic member 34, both ends of the connecting rod 33 are respectively connected to the two long grooves in a sliding manner, and the elastic member 34 is used to provide the connecting rod 33 with an elastic force for moving away from the sliding path of the material door 22 to the collection box 31; the material scraping plate 32 is connected to the connecting rod 33. The elastic force of the elastic member 34 ensures that the material scraping plate 32 is always in close contact with the sliding path of the material door 22, and even if the material door 22 is subjected to a certain impact or vibration during the sliding process, the material scraping plate 32 can remain stable and effectively scrape off the metal powder; through the elastic force of the elastic member 34, the material scraping plate 32 can be more closely attached to the sliding path of the material door 22, effectively scraping off the metal powder, and improving the completeness and efficiency of cleaning.

[0051] Further, the scraping side includes a first wedge-shaped slope close to the material port 21, a second wedge-shaped slope away from the material port 21, and a top edge formed by the intersection of the first wedge-shaped slope and the second wedge-shaped slope; the first magnetic attraction piece 30 is provided with a third wedge-shaped slope on the side facing the opening position of the material door 22, and the first magnetic attraction piece 30 is provided with a fourth wedge-shaped slope on the side facing the closing position of the material door 22; the first wedge-shaped slope corresponds to the third wedge-shaped slope and has the same slope, and the second wedge-shaped slope corresponds to the fourth wedge-shaped slope and has the same slope.

[0053] Specifically, when the material door 22 moves along the slide rail to the closed state, the power contact protrusion is in contact with the power contact strip, the first electromagnet is powered on, and the adsorption of the metal powder in the light tunnel 25 is started. After the light tunnel is completed, the material door 22 is translated along the slide rail to be opened, the power contact protrusion is separated from the power contact strip, the first electromagnet is powered off, and the adsorbed metal powder naturally falls into the collection box 31 under the action of gravity. In this embodiment, the power-on and power-off of the electromagnet is synchronized with the opening and closing of the material door 22, without the need for additional control operation, further improving the degree of automation of the equipment.

[0057] In this embodiment, the material door 22 is provided with an electric conductor at the terminal point of moving towards the accommodating groove 23, and the electric conductor is electrically connected to the power supply. The collection box 31 is provided with a power contact groove corresponding to the electric conductor, and the bottom of the collection box 31 is paved with a second magnetic attraction member 311 which is an electromagnet and is electrically connected to the power contact groove.
