Through the above mechanism, the cup body 8 can be automatically fixed, and the problem that the cup body 8 slips from the hand during the polishing can be avoided, and the safety of the worker during the trimming is improved.

[0027] Example three

[0028] Please refer to Figures 1-4On the basis of embodiment one and embodiment two, the utility model provides a technical scheme: polishing mechanism 3 includes motor 301, motor 301 fixed connection is in the bottom of connecting plate 7, and the output fixed connection of motor 301 has first gear 302, and the one end away from motor 301 of first gear 302 is fixedly connected with second electric push rod 204, and the inside rotation connecting of spacing sliding slot 206 has rotating rod 304, and the one end away from first electric push rod 202 of rotating rod 304 is through work table 1, and fixedly connected with second gear 303, and first gear 302 is engaged with second gear 303, and the outside sleeve of rotating rod 304 has polishing column 306, and polishing column 306 is oval, and the outside fixed connection of work table 1 has baffle 305, and the material of baffle 305 is transparent acrylic.

[0029] In the embodiment, when the cup body 8 is fixed, the motor 301 is started, the first gear 302 is driven to rotate by the output end of the motor 301, the second electric push rod 204 is driven to rotate by the rotation of the first gear 302, the rubber column 205 is driven to rotate by the rotation of the second electric push rod 204, and the cup body 8 and the first electric push rod 202 are also rotated when the rubber column 205 rotates because the rubber column 205 and the rubber suction cup 203 have clamped the cup body 8. At this time, the corners of the cup body 8 will contact the polishing column 306. Because the first gear 302 is engaged with the second gear 303, the second gear 303 will rotate when the first gear 302 rotates. The rotating rod 304 is driven to rotate by the rotation of the second gear 303. The polishing column 306 is driven to rotate by the rotation of the rotating rod 304, so as to polish and trim the corners of the cup body 8. The residues will fall into the discharge box 5.

Then, drive the cup body 8 to slide in the inside of the spacing sliding slot 206 by the pushing of the rubber suction cup 203. Because the polishing column 306 is oval, the cup body 8 will contact the polishing column 306 when it slides in the inside of the spacing sliding slot 206, until the baffle 305 covers the cup body 8. At this time, start the second electric push rod 204, and push the rubber column 205 to a specified appropriate position by the pushing of the second electric push rod 204, so that the rubber column 205 can contact the bottom of the inner cavity of the cup body 8, to achieve the effect of fixation.

[0031] When the cup body 8 is fixed, the motor 301 is started, the first gear 302 is driven to rotate through the output end of the motor 301, the second electric push rod 204 is driven to rotate through the rotation of the first gear 302, the rubber column 205 is driven to rotate through the rotation of the second electric push rod 204, and the cup body 8 and the first electric push rod 202 are driven to rotate with the rubber column 205 when the rubber column 205 rotates because the rubber column 205 and the rubber suction cup 203 have clamped the cup body 8. At this time, the corners of the cup body 8 will contact the polishing column 306. Because the first gear 302 and the second gear 303 are engaged, the second gear 303 will rotate with the first gear 302 when the first gear 302 rotates, the rotating rod 304 is driven to rotate through the rotation of the second gear 303, the polishing column 306 is driven to rotate through the rotation of the rotating rod 304, and the corners of the cup body 8 are polished and edged, and the residues will fall into the discharging box 5. When the edging is completed, the first electric push rod 202 is started, and the rubber suction cup 203 will take the cup body 8 out to the outside of the baffle 305. At this time, the operator takes the cup body 8 and places it at a designated position.
