ABSTRACT:
A pipe centering apparatus is of such a structure that pipes of certain kinds such as aluminum short pipes transported by a conveyor are centered with their longitudinal centers aligned with each other, before the pipes are subjected to chamfering or other processes. The pipe centering apparatus in the invention comprises a pair of right and left gears in mesh with each other and rotatably mounted on a main frame, a pair of right and left racks respectively in mesh with the right and left gears, and a pair of right and left regulators respectively secured to the right and left racks so as to come into contact with ends of the pipes, wherein the gears are rotated to cause the regulators to move towards each other and to contact the pipe ends, thereby precisely centering the pipes even where the pipes are not of strictly the same length.
