[0001] The embodiment of the utility model relates to bicycle seat tube reaming technical field, more specifically, the utility model relates to a kind of reaming equipment for bicycle seat tube. BACKGROUND

[0002] Bicycle seat tube is the key force component connecting frame and seat, and its manufacturing process usually includes pipe cutting, end forming and welding steps.Currently, mainstream seat tube is processed by welding process using metal pipe material (such as aluminum alloy, steel alloy), and common welding methods include argon arc welding or brazing.During welding process, the heated and molten metal material is prone to form continuous weld line (also known as weld tumor) on inner wall after cooling, resulting in reduced effective inner diameter and increased surface roughness of seat tube.

[0003] Since the weld line is irregularly protruding and extends longitudinally along the weld seam, when the operator tries to insert the support vertical rod of bicycle seat into the seat tube, local interference will occur between the outer surface of vertical rod and weld line area.Although there are reaming equipment on the current market that can remove weld line inside seat tube, unfortunately, the removed chips are often left or accumulated inside seat tube, which affects the reaming accuracy of seat tube, and the left or accumulated chips also easily have adverse effects on reamer, such as increasing the wear of reamer. SUMMARY
