[0033] In the embodiment provided by the present application, the adjusting unit includes a first protective cover 2 fixedly connected to the top plate 1. An accommodating space is formed inside the first protective cover 2. An air motor 4 is detachably connected inside the accommodating space. At least part of the output end of the air motor 4 extends to the outside of the first protective cover 2, and a mounting plate 5 is fixedly connected to the output end of the air motor 4. A fixing plate 6 is fixedly connected to the side of the mounting plate 5 away from the air motor 4, and a cylinder 8 is fixedly connected to the side of the fixing plate 6 away from the mounting plate 5. Among them, the output end of the cylinder 8 is communicated with the air motor 4 through a pipeline.
[0034] The specific structures of the air motor 4 and the cylinder 8 can refer to the technical solutions in the prior art. Those skilled in the art can know and will not be elaborated here. The connection mode between the cylinder 8 and the air motor 4 is a conventional means in the prior art, so it is not shown in the drawings.

[0038] The shape of the grinding surface of the grinding disc 14 is not limited herein and can be adjusted according to the grinding requirements.
[0039] In the embodiments provided by the present application, the grinding assembly includes a connecting plate 16 fixedly connected to the side of the connecting member 7 away from the grinding disc 14. A first grinding shaft 17 is rotatably connected to the connecting plate 16. An inner grinding wheel 20 and an outer grinding wheel 21 are fixedly connected to the first grinding shaft 17. One end of the first grinding shaft 17 extends to the outside of the connecting plate 16. The inner grinding wheel 20 is located outside the connecting plate 16, and the outer grinding wheel 21 is located between the inner walls of the connecting plate 16.
[0040] It should be explained that the outer grinding wheel 21 and the second protective cover 9 are on the same plane, and the inner grinding wheel 20 and the second protective cover 9 are on different planes (it can be understood that there is a certain distance between the inner grinding wheel 20 and the second protective cover 9). In this way, when grinding the inner side wall of the workpiece, the second protective cover 9 will not rub against the workpiece, thus ensuring the grinding quality of the workpiece.

[0045] In the embodiments provided by the present application, the grinding disc 14 and the outer grinding wheel 21 are located on the same plane, and the size of the outer grinding wheel 21 is larger than that of the inner grinding wheel 20.
[0046] This can avoid the situation of grinding dead corners when grinding the inner side wall of the workpiece. In addition, patterns can be set on the inner grinding wheel 20 and the outer grinding wheel 21 to meet the special grinding requirements of the workpiece.
[0047] The usage method of the present utility model: When grinding a workpiece, first install the device on the driving device through the top plate 1. Control the rotation of the pneumatic motor 4 through the cylinder 8 to adjust the angle of the device and replace the grinding head. It is also possible to drive the top plate 1 to rotate through the driving device to adjust the overall angle of the device to achieve the purpose of multi-angle adjustment. When grinding the end face of the workpiece, rotate the grinding disc 14 to a position parallel to the workpiece; when grinding the outer side wall of the workpiece, rotate the outer grinding wheel 21 to be parallel to the outer side wall of the workpiece and make the grinding disc 14 located outside the workpiece, which will not affect the grinding of the workpiece at this time; when grinding the inner corner of the workpiece, rotate the inner grinding wheel 20 to the inside of the workpiece and make the outer grinding wheel 21 located above the workpiece, that is, only the inner grinding wheel 20 is inside the workpiece at this time, so as to ensure the stability of grinding the inner corner of the workpiece.
[0048] The above are only the preferred embodiments of the present utility model, but the present utility model is not limited by the scope shown in the drawings. Any changes made according to the concept of the present utility model, or modified into equivalent embodiments with equivalent changes, should still be within the protection scope of the present utility model as long as they do not exceed the spirit covered by the description and the drawings.
