Abstract

The invention relates to a guide sleeve reaming machine, which comprises a base body and a reamer mechanism arranged on the base body, wherein the reamer mechanism comprises a motor and a cutter permanent seat fixedly connected to a rotor of the motor; the cutter permanent seat is fixedly provided with a reamer of which the axial lead is vertical to a horizontal plane, and the base body is fixedly provided with a pair of guide posts of which the axial leads are vertical to the horizontal plane; the pair of the guide posts is sleeved with a positioning mold in a sliding mode respectively, and the positioning mold is provided with a first taper positioning hole; the tops of the pair of the guide posts are provided with an upper mould respectively, and the upper mould is provided with a second taper positioning hole; and when a guide sleeve is processed, the guide sleeve to be processed is fixedly placed between the first positioning hole and the second positioning hole; because the central lines of the first positioning hole and the second positioning hole are superposed with the axial lead of the reamer respectively, when the reamer of the reamer mechanism is fed to ream on the guide posts, the axial lead of the central hole of the guide sleeve can be ensured to be superposed with the axial leads of an inner pipe and an outer pipe.

Description

technical field [0001] The invention relates to a reaming machine. Background technique [0002] In the prior art, telescopic pipe fittings are usually composed of an outer pipe and an inner pipe that is slidably inserted into the outer pipe. Due to the harsh sound that will be emitted when the metal inner pipe and the outer pipe rub against each other, it will generally appear at the end of the outer pipe. A plastic guide sleeve is set, the inner tube passes through the plastic guide sleeve and the end is inserted in the outer tube, which not only reduces noise but also plays a buffering role. For example, folding chairs or liftable computer chairs are often provided with such telescopic tubes. However, since the plastic guide bush is usually formed by injection molding, the shape is irregular, and the size of its center hole is not accurate enough, especially it cannot be guaranteed that the axis line of the center hole of the guide sleeve coincides with the axis lines of ...
