Technical Field
The invention relates to the field of flange processing, in particular to flange processing equipment.
Background

The working principle is that the reversing valve 24 is provided with three working positions, three clamping modes can be realized by precisely controlling the switching position of the reversing valve 24, when the flange outer ring needs to be polished, the reversing valve 24 is switched to a position communicated with the inner side air channel 19 in the middle of the polishing table 3, compressed air pushes the clamping plate I14 at the inner ring to move towards the flange inner ring to clamp the single side, at the moment, the clamping plate II 15 at the outer ring keeps static to provide an outer ring processing space for the polishing head 12, when the flange inner ring needs to be polished, the reversing valve 24 is switched to a position communicated with the inner side air channel 19 in the periphery of the polishing table 3, compressed air pushes the clamping plate II 15 at the outer ring to move towards the flange outer ring to clamp the single side, at the moment, the clamping plate I14 at the inner ring keeps static to ensure that the polishing head 12 can go deep into the flange inner ring, and when the flange end face needs to be polished, the reversing valve 24 is switched to a position simultaneously communicated with the inner side air channel 19 in the middle and the periphery, the compressed air synchronously pushes the clamping plate I14 and the clamping plate II 15 to move towards each other to realize clamping from the inner ring and clamping the flange at the same time, at the moment, the flange is fixed in two directions, and axial cutting force can be born when the end face is polished. The first motor 29 drives the worm 32 to rotate, the worm 32 drives the worm wheel 31 to enable the gear 30 to be meshed with the gear ring 5, and the grinding table 3 is driven to rotate stably along the annular guide rail 33. The three-axis linkage system realizes transverse movement through the first electric slide rail 7, the second electric slide rail 8 realizes vertical adjustment, the third electric slide rail 9 realizes longitudinal feeding, and the second motor 11 drives the polishing head 12 to rotate to finish precise polishing. The negative pressure pump 35 generates negative suction when working, metal scraps and dust generated in the polishing process are continuously sucked through the dust suction port 34, dust-containing air flows into the upper space of the filter box 6 through the negative pressure pipe 36, metal scraps and dust are effectively trapped in the filter box 42 when the dust passes through the filter screen 43, filtered normal-temperature clean air continuously flows downwards and is discharged from the exhaust end of the negative pressure pump 35 through the connecting pipe 37, and the second exhaust pipe 38 guides the part of filtered clean air into the machine box 1. Because the air pump 4, the negative pressure pump 35, the first motor 29 and other devices in the case 1 continuously run to generate heat, the temperature of the internal air is increased, when the normal-temperature air discharged by the second exhaust pipe 38 enters the case 1, forced convection heat exchange is carried out between the normal-temperature air and the hot air, on one hand, the normal-temperature air directly washes the surfaces of the heating components to take away heat, and on the other hand, directional air flow disturbance is formed in the case 1, so that the hot air and the air after heat exchange are discharged through the air outlet 39 on the left side of the case 1. The dust screen 40 provided inside the exhaust port 39 can effectively prevent external dust from entering the cabinet 1.
