[0003] The utility model patent application document with publication number "CN213034241U" discloses a burr removal device for flange processing, which is mainly composed of a supporting base, a mounting rail, a second push cylinder, a cylinder fixing frame, a first push cylinder, a motor housing, a drive motor, a grinding wheel and a dustproof housing. This technical solution prevents the generated dust from flying into the air by providing a dustproof structure, and is also provided with a structure for collecting dust to facilitate later recycling.

[0004] The burr removal device for flange processing disclosed in the above document has the following defects: the burr removal device places the flange on a workpiece fixing seat and then grinds the flange with a grinding wheel. However, during use, only one side of the flange can be grinded at a time. The staff is required to first remove the flange from the workpiece fixing seat and turn it over, and then re-fix the flange on the workpiece fixing seat before grinding the other side of the flange. This is inconvenient to operate and indirectly reduces the grinding efficiency. Utility Model Content

[0027] A slide groove is provided at the inner bottom of the housing 1, and a bidirectional screw 10 is rotatably connected inside the slide groove. Two sliders 11 are threadedly connected to the outer surface of the bidirectional screw 10. The upper surfaces of the two sliders 11 are hinged with a connecting plate 12, and the other end of the connecting plate 12 is hinged with a supporting plate 13. A flange 9 is installed on the upper surface of the supporting plate 13. A third motor 14 is provided at one end of the housing 1 away from the placement seat 101.

The sliders 11 are all located inside the slide groove, and the sliders 11 move along the axial direction of the slide groove.

[0028] The outer surface of the cover plate 2 is provided with an observation window 201;

[0029] When in use, the staff pulls the cover plate 2 outwards through the handle 3, so that the cover plate 2 rotates around the hinge point and opens the front opening of the shell 1, and then starts the third motor 14, so that the output end of the third motor 14 drives the bidirectional screw 10 to rotate through the coupling. During the rotation of the bidirectional screw 10, the two sliders 11 are driven to move in opposite directions along the slide groove, and the height of the support plate 13 is adjusted through the hinged connecting plate 12 to make it drop to a low position, and then the flange 9 to be processed is placed horizontally on the upper surface of the support plate 13. Ensure that the center is aligned with the arc plate 802, manually rotate the knobs 807 on the arc plates 802 on both sides, so that the knobs 807 drive the one-way screw 806 to move in the threaded hole, and push the clamping plate 808 to move toward the edge of the flange 9, until the clamping plate 808 is tightly abutted against the flange 9, and the clamping and fixing are completed, and then the cover plate 2 is pushed to close the front opening of the housing 1, and then the third motor 14 is started in the reverse direction to reset the slider 11, and at the same time, the support plate 13 and the flange 9 are driven to move upward through the connecting plate 12;

When the surface of the grinding wheel 7 contacts the outer surface of the flange 9, the electric push rod 4 is closed, and by starting the first motor 6, the output end of the first motor 6 drives the grinding wheel 7 to rotate, so that the grinding wheel 7 grinds the surface of the flange 9.

[0031] After one side of the flange 9 is polished, the electric push rod 4 is operated so that the output end of the electric push rod 4 drives the support frame 5 to reset, so that the grinding wheel 7 and the flange 9 are no longer in contact, and the third motor 14 is started so that the output end of the third motor 14 drives the bidirectional screw 10 to rotate through the coupling. During the rotation of the bidirectional screw 10, the two sliders 11 are driven to move in opposite directions along the slide groove, and the height of the support plate 13 is adjusted through the hinged connecting plate 12 to make it drop to a low position. Then, the second motor 804 is started so that the output end of the second motor 804 drives the driving gear 805 to rotate. Since the driving gear 805 is meshed with the driven gear 803, the driven gear 803 drives the rotating shaft 801 to rotate synchronously, and the rotation of the rotating shaft 801 It will synchronously drive the arc plates 802 on both sides and the clamped flange 9 to flip around the rotating shaft 801 axially. When the flange 9 flips to the target angle, the second motor 804 is turned off. At this time, the flipping operation of the flange 9 is completed. Then, the third motor 14 is reversely started to reset the slider 11. At the same time, the support plate 13 and the flange 9 are driven to move upward through the connecting plate 12. Then, the electric push rod 4 is started so that the output end of the electric push rod 4 pushes the support frame 5 and the first motor 6 to move downward.

By starting the first motor 6, the output end of the first motor 6 drives the grinding wheel 7 to rotate, so that the grinding wheel 7 grinds the other surface of the flange 9.

[0032] When both sides of the flange 9 are polished, the electric push rod 4 is operated so that the output end of the electric push rod 4 drives the support frame 5 to reset, so that the grinding wheel 7 and the flange 9 are no longer in contact, the cover plate 2 is opened, and the knob 807 is rotated in the opposite direction so that the clamping plate 808 cancels the clamping of the flange 9, and then the polished flange 9 can be removed from the support plate 13 to complete the polishing process;

[0033] A through opening is provided on the back of the housing 1, and a dust collecting structure 15 is provided inside the through opening. The dust collecting structure 15 includes a shell 1501, and the shell 1501 is installed inside the through opening.

A fan blade 1504 is installed at the output end of the fourth motor 1503;

[0034] One end of the housing 1501 is provided with a mounting groove, a magnetic block 1505 is installed inside the mounting groove, one end of the housing 1501 is magnetically connected to a baffle 1506 through the magnetic block 1505, and a plurality of exhaust holes are provided on the outer surface of the baffle 1506;

[0035] During grinding, by starting the fourth motor 1503, the output end of the fourth motor 1503 drives the fan blades 1504 to rotate at a high speed.

[0037] The dust entering the shell 1501 can be filtered by the filter 1508. After being intercepted by the filter 1508, the clean air is discharged from the exhaust hole of the baffle 1506. By pushing the side panel 1507 above the shell 1501 upward, it slides along the opening until it is completely separated from the shell 1501. After that, the filter 1508 can be gently pulled out from the installation port of the side panel 1507 and cleaned.
