A notch is provided on the side of the collection plate away from the flange, and the notch connects the collection cavity with the outside world. A screw cover is threadedly connected to the notch.

[0007] Optionally, the grinding shaft includes a grinding rod mounted on the adapter block, a slide groove is provided on the outer peripheral side of the grinding rod, the collecting assembly cooperates with the slide groove, and the rotation of the grinding rod can drive the collecting assembly to rotate synchronously.

[0008] Optionally, an upper spring is fixed between the adapter block and the end surface of the upper collecting plate.

[0009] Optionally, a magnetic block is detachably mounted on the bottom of the grinding rod, a lower spring is fixedly mounted between the magnetic block and the end surface of the collecting plate on site, and the magnetic block and the grinding rod are connected by magnetic force.

[0010] Optionally, the suction force between the magnetic block and the polishing rod is greater than the elastic force of the lower spring.

[0011] In summary, compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Due to the setting of the collecting component, the iron filings generated by the grinding rod can be swept into the inlet through the inlet in the collecting tray, and then enter the collecting chamber through the arc channel and the action of centrifugation, which effectively prevents the iron filings from being scattered everywhere and difficult to clean, and also avoids air pollution.

[0017] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention.

[0018] As shown in Figure 1-3, a flange inner hole grinding device includes a motor bin 10, on which a transfer block 11 is installed, and the characteristics are: a grinding shaft is installed on the transfer block 11, and two collecting components are sleeved on the grinding shaft, and the collecting component includes a collecting plate 14, and a flange 13 is clamped between the two collecting plates 14, an upper spring 18 is fixed between the transfer block 11 and the end face of the upper collecting plate 14, at least two inlets 17 are provided in the collecting plate 14, and an annular collecting chamber 16 is also provided in the collecting plate 14, and the inlet 17 is connected with the collecting chamber 16, and a notch is provided on the side of the collecting plate 14 away from the flange 13, and the notch connects the collecting chamber 16 with the outside, and a screw cover 15 is threadedly connected to the notch.

[0019] The grinding shaft includes a grinding rod 12 installed on the adapter block 11. A slide groove is provided on the outer peripheral side of the grinding rod 12. The collecting assembly cooperates with the slide groove. The rotation of the grinding rod 12 can drive the collecting assembly to rotate synchronously. A magnetic block 20 is detachably installed on the bottom of the grinding rod 12. A lower spring 19 is fixedly installed between the magnetic block 20 and the end face of the on-site collecting plate 14. The magnetic block 20 and the grinding rod 12 are connected by magnetic force. The suction force between the magnetic block 20 and the grinding rod 12 is greater than the elastic force of the lower spring 19.

[0020] When in use, the magnetic block 20 and the collecting assembly on the lower side can be directly removed first, and then the polishing rod 12 can be inserted into the hole of the flange 13, and then the collecting plate 14 on the lower side and the magnetic block 20 can be mounted on the polishing rod 12. At this time, the lower spring 19 and the upper spring 18 are both in a compressed state, and then the motor compartment 10 can be started to rotate the polishing rod 12 to polish the hole of the flange 13. The rotation of the polishing rod 12 will drive the collecting plate 14 to rotate through the inlet 17 in the collecting plate 14, and the iron filings generated by the polishing of the polishing rod 12 can be swept into the inlet 17, and then enter the collecting chamber 16 through the arc channel and the action of centrifugation, effectively avoiding the iron filings from being scattered everywhere and not easy to clean, and also avoiding air pollution. When the collecting chamber 16 is full, the screw cover 15 needs to be rotated to be removed, and then the iron filings in the collecting chamber 16 can be directly poured out.

[0021] After the current hole is polished, when the next hole needs to be replaced, since the magnetic block 20 is in a magnetic state and is easy to disassemble, the magnetic block 20 can be directly unplugged, and then the polishing rod 12 is inserted into the next hole and the magnetic block 20 is installed.

[0022] Obviously, the described embodiments are only a part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
