Perforated pipe burr removing machine and centering device thereof

Abstract

The invention discloses a perforated pipe burr removing machine and a centering device thereof. The centering device comprises a first positioning disc and a second positioning disc which are oppositely arranged. Through holes for the power head of the burr removing machine to penetrate are arranged in the central parts of the first positioning disc and the second positioning disc. The first positioning disc and the second positioning disc are connected through at least three guide ribs. The at least three guide ribs are outwards protruding arc-shaped and protrude the outer edges of the first positioning disc and the second positioning disc in the radial direction. The centering device provided by the invention not only can guarantee the power head to be in the center, but also can effectively reduce iron chip resistance.

Description

technical field [0001] The invention relates to the technical field of pipe fitting processing equipment, in particular to a punching pipe deburring machine and a centralizer thereof. Background technique [0002] The inner wall of the perforated pipe has a lot of burrs, which need to be removed with a deburring machine. Such as figure 1 , 2 as shown, figure 1 It is a structural sectional view of the power head part of the existing perforated tube destacker in the perforated tube; figure 2 for figure 1 end view of the. The power head 101 of the perforated pipe destacker realizes the advance and retreat movement by external force. The power head 101 drives the cutting tool 108 to puncture the inside of the punching tube 102, and the power head 101 should be centered in the punching tube 102 to ensure that it is coaxial with the punching tube 102. [0003] In the prior art, the perforated pipe destacker does not have a special centralizer. The perforated tube destacke...

AI Technical Summary

Problems solved by technology

During the working process of the perforated pipe destabbing machine, because a large amount of iron filings will be produced in the perforated pipe 102, the iron filings will block the movement of the connecting disc 104 and the positioning disc 107, and the connecting disc 104 and the positioning disc 107 will be in contact with the iron filings. The contact area is too large, resulting in excessive resistance of iron filings, so the connecting plate 104 and positioning plate 107 are often blocked by accumulated iron filings, and the perforated tube deburring machine cannot work normally.
