[0035] Thus, when the pipe body is moved by the conveying mechanism 204 to be conveyed or manually fed to the chamfering device 3, the fifth driving member 302 will be started to drive the chamfering disc 303 to rotate, and then the third push-pull machine 301 will push the chamfering disc 303 to move towards the pipe body, so that the chamfering disc 303 will polish and chamfer the end of the pipe body when the chamfering disc 303 contacts the pipe body. After the chamfering is completed, the third push-pull machine 301 pulls the chamfering disc 303 back, and then the fifth driving member 302 stops working. The third push-pull machine 301 can directly control the movement of the chamfering disc 303 towards the pipe body, or control the movement of the pipe body towards the chamfering disc 303. Other relative movements in this application can be in this form. The sixth driving member 304 drives the connecting plate 305 to rotate during polishing, so that the two chamfering discs 303 on the connecting plate 305 are simultaneously driven to rotate. Since each of the two chamfering discs 303 is driven to rotate by the fifth driving member 302, the pipe body can be polished and chamfered more quickly, and the residues after polishing are more easily dropped from the gap between the two chamfering discs 303 and are not easily left on the chamfering disc 303.

[0036] Preferably, the embodiment further comprises a thimble 306, which is arranged in the gap between the two chamfering discs 303.

[0037] Thus, the thimble 306 is inserted into the inner hole of the pipe body to position the pipe body during polishing. After the tapered head of the thimble 306 is inserted into the inner hole, the end angle of the pipe body is adjusted to be perpendicular to the chamfering disc 303, so that the chamfering is more accurate.
