[0013] The above technical solution of the present utility model has the following advantages compared with the prior art:

[0014] A corner grinding device for a thin-walled flywheel housing according to the present utility model. When processing the thin-walled flywheel housing, the thin-walled flywheel housing is placed on the top surface of the semi-circular lapping platen. At the same time, the slider and the second slider are moved oppositely on the surface of the first chute at the middle position of the lapping processing table, so as to clamp the thin-walled flywheel housing onto the inner side wall surface of the docking block. At the same time, the extrusion soft block on the outer surface of the positioning sleeve is softly attached to the surface of the thin-walled flywheel housing, thereby increasing the anti-slip force between the extrusion soft block and the surface of the thin-walled flywheel housing. At the same time, it can elastically buffer the slight vibration of the thin-walled flywheel housing during grinding, and avoid the high-frequency vibration during grinding of the thin-walled flywheel housing from causing loosening and then falling off between the thin-walled flywheel housing and the clamping device. The sliding column on the inner side wall surface of the positioning sleeve slides telescopically on the inner side wall surface of the groove, compresses and fits the surfaces of thin-walled flywheel housings with different sizes and shapes. At the same time, the elastic wires on the inner side wall surface of the groove elastically push the sliding column, so that the extrusion soft block can be closely attached to the surface of the thin-walled flywheel housing. The elastic push of multiple elastic wires can effectively prevent the thin-walled flywheel housing from shaking during grinding.

[0015] A corner grinding device for a thin-walled flywheel housing according to the present utility model. When the thin-walled flywheel housing is fixed on the top surface of the slider, the lifting table is used to raise the lapping processing table. At the same time, a grinding machine is used to polish and grind the thin-walled flywheel housing inside the slider. When polishing and grinding the thin-walled flywheel housing, at the same time, an air extraction pipe is used to recover and divert some burr debris floating in the air into the dust collection box. Along with the recovery of the floating burr debris, it is avoided that when the thin-walled flywheel housing is polished and ground, the burrs are of different sizes. The large burrs are relatively large in granular shape and can be cleaned later by a broom or a blowing gun. However, the small burr debris is relatively small and is easy to adhere to the surface of the processing table or inside some mechanical joints. Multiple frictions will cause wear of the mechanical equipment.

[0016] A corner grinding device for a thin-walled flywheel housing according to the present utility model. When the air extraction pipe is used to divert the ground burr debris into the dust collection box, the inclined plate is used to compress and limit the incoming air, so that the air flow can only flow in the gap between the third chute and the inclined plate. At the same time, the semi-circular groove on the bottom surface of the third chute is used to drain and push the downward air flow upward, so that the burr debris stays and splashes inside the dust collection box. Under the action of the narrow space between the inclined plate and the semi-circular groove and the air flow, it is greatly reduced that the burr debris inside the dust collection box will flow back and be discharged again along the narrow space between the inclined plate and the semi-circular groove.

[0027] When processing the thin-walled flywheel shell, the thin-walled flywheel shell is placed on the top surface of the semicircular overlapping table 127, and the slider 12 and the second slider 128 are moved simultaneously on the surface of the slide groove 112 at the middle position of the overlapping processing table 111, so that the thin-walled flywheel shell is clamped to the inner wall surface of the docking block 122, and the extrusion soft block a6 on the outer surface of the positioning sleeve 126 is softly attached to the surface of the thin-walled flywheel shell, thereby increasing the anti-slip force between the extrusion soft block a6 and the surface of the thin-walled flywheel shell, and at the same time, the thin-walled flywheel shell can be polished to prevent the slight vibration of the thin-walled flywheel shell. Elastic buffering can prevent the high-frequency vibration of the thin-walled flywheel shell during further grinding, which may cause loosening and subsequent falling off between the thin-walled flywheel shell and the clamping device; the sliding column a4 on the inner wall of the positioning sleeve 126 can be telescopically slid on the inner wall of the groove a1 to compress and fit the surfaces of thin-walled flywheel shells of different sizes and shapes, and at the same time, the elastic wire a2 on the inner wall of the groove a1 can elastically push the sliding column a4, so that the extruded soft block a6 can be tightly fitted on the surface of the thin-walled flywheel shell.

[0028] Reference Figure 1 - Figure 5As shown, in an embodiment of the present utility model, limiting blocks a3 are fixedly connected to the inner wall surfaces on the upper and lower sides of the groove a1.

A blowing and cooling pipe 125 is fixedly connected to the output end of the air blower 124 and is provided on the outer surface of the heightening support block 121.

The air extraction pipe 115 and one end of the blowing pipe 114 extend to the outer edge position of the output end of the grinding machine 13;

[0029] When the thin-walled flywheel housing is fixed on the top surface of the slider 12, the lifting platform 11 is used to lift the overlapping processing table 111. At the same time, the grinding machine 13 is used to polish the thin-walled flywheel housing inside the slider 12. When polishing the thin-walled flywheel housing, the air extraction pipe 115 is used to recover and guide some burr debris floating in the air into the dust collection box 14. Along with the recovery of the floating burr debris, it is avoided that when the thin-walled flywheel housing is polished, the burrs are of different sizes. The large burrs are relatively large in granular shape and can be cleaned by a broom or a blowing gun later. However, the small burr debris is relatively small and is easy to adhere to the surface of the processing table or inside some mechanical joints. Multiple frictions will cause wear of the mechanical equipment.

[0030] Refer to Figure 1 - Figure 2 and Figure 6 As shown, in an embodiment of the present utility model, a chip inlet hole 142 is provided on the top surface of the dust collection box 14. A concentration box 141 is movably sleeved on the inner wall surface of the dust collection box 14. A slide groove 143 is provided on the inner wall surface of the concentration box 141. An inclined plate 145 is fixedly connected to the inner wall surface of the concentration box 141 and at the top edge position of the slide groove 143.

A hollow soft block 146 is fixedly connected to one side surface of the inclined plate 145 and is provided at the top edge position of the semi-circular groove 144;

[0031] When the exhaust pipe 115 is used to guide the burrs and debris that are polished into the dust box 14, the inclined plate 145 is used to compress and limit the incoming air, so that the airflow can only flow in the gap between the slide groove three 143 and the inclined plate 145. At the same time, the semicircular groove 144 on the bottom surface of the slide groove three 143 is used to guide and push the downward airflow upward, so that the burrs and debris stay and splash inside the dust box 14, and then through the narrow space between the inclined plate 145 and the semicircular groove 144 and the push of the airflow, the burrs and debris inside the dust box 14 are greatly reduced and will not flow back and be discharged along the narrow space between the inclined plate 145 and the semicircular groove 144.

[0032] Working principle: Place the thin-walled flywheel shell on the top surface of the semicircular overlap table 127, and at the same time, cooperate with the slider 12 and the second slider 128 to move simultaneously on the surface of the slide groove 112 at the middle position of the overlap processing table 111, so that the thin-walled flywheel shell is clamped on the inner wall surface of the docking block 122, and at the same time, cooperate with the extrusion soft block a6 on the outer surface of the positioning sleeve 126 to softly fit on the surface of the thin-walled flywheel shell, thereby increasing the anti-slip force between the extrusion soft block a6 and the surface of the thin-walled flywheel shell, and at the same time, the thin-walled flywheel shell can be clamped on the inner wall surface of the docking block 122. The body elastically buffers the slight vibration of the thin-walled flywheel shell during grinding; the sliding column a4 on the inner wall of the positioning sleeve 126 is telescopically slid on the inner wall of the groove a1 to compress and fit the surface of the thin-walled flywheel shell of different sizes and shapes, and the elastic wire a2 on the inner wall of the groove a1 is elastically pushed to the sliding column a4, so that the extrusion soft block a6 can be tightly fitted on the surface of the thin-walled flywheel shell. The elastic push of multiple elastic wires a2 can effectively prevent the thin-walled flywheel shell from shaking during grinding;

[0033] When the thin-walled flywheel shell is fixed on the top surface of the slider 12, the overlapping processing table 111 is raised in cooperation with the lifting platform 11, and the thin-walled flywheel shell inside the slider 12 is polished and grinded in cooperation with the grinder 13. When the thin-walled flywheel shell is polished and grinded, the fan 113 is used to inject gas into the inside of the air pipe 114, and the flowing gas will blow up the burrs and debris on the top surface of the overlapping processing table 111, and at the same time, the exhaust pipe 115 is used to recover some burrs and debris floating in the air and guide them into the dust box 14 to be recovered along with the scattered burrs and debris.

[0034] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here.
