Abstract

The invention relates to fast dismounting repeating use counter bore shaft. It has counter bore mechanical construction. Its technical proposal is as follows: it includes nut, counter bore shaft body, rising tightening pin; the center of the shaft body is set inner cone shape pin hole; and its axial is set one opening slit. The rising tightening pin has one screw-thread section, pin body, and torsional channel. The pin is set at pin hole. And the nut is set screw-thread section. It has the advantages of easy dismounting, no components damage, and repeating use.

Description

technical field [0001] The invention relates to a quick-release and reusable counterbore shaft, which belongs to a quick-detachable and reusable counterbore shaft with a counterbore mechanical structure. Background technique [0002] At present, in the mechanical connection structure, the counterbore shaft with interference fit or transition fit is often used for connection. When disassembling parts joined using this method, it is often necessary to damage the part or damage the counterbore shaft to remove them. If the supporting bearings on both sides of the fork of the rail roadway stacker are to adopt the above-mentioned structural form. As the supporting bearing of the fork of the rail roadway stacker is a vulnerable part, when the bearing is damaged and needs to be replaced, the counterbore shaft and the counterbore are too tight to disassemble, even if the bearing is damaged by destructive methods, it cannot be removed counterbore shaft. Therefore, the existing coun...
