Abstract

A machining device of prestressed reinforced concrete hollow pile internal threads comprises a machine body, the machine body can move relative to a machining mold of prestressed reinforced concrete hollow piles to-be-machined, the rack and the machining mold of the prestressed reinforced concrete hollow piles are driven by an identical driving shaft, a cutter shaft is installed on the rack, the position, relative to the rack, of the cutter shaft can be adjusted, a cutter head is arranged on the cutter shaft, a worm wheel is movably connected on the rack and driven by a driving worm, and a speed change mechanism is arranged between the driving worm and a driving shaft of the machining mold of the prestressed reinforced concrete hollow piles to-be-machined. The speed ratio of the driving wheel to the driven wheel of the speed change mechanism corresponds to the speed ratio of the machining mold of the prestressed reinforced concrete hollow piles to-be-machined to a driving wheel of the machining mold, an adjusting screw is fixed on the cutter shaft and adjusts the upper and lower positions of the cutter shaft, the adjusting screw is movably connected with the rack, and a waste residue collecting device is fixedly connected on the cutter shaft. The machining device is used for machining the prestressed reinforced concrete hollow pile internal threads, simple in structure, high in machining efficiency, controllable in machining accuracy and convenient to use and maintain.

Description

technical field [0001] The invention relates to internal thread processing equipment, in particular to internal thread processing equipment for prestressed reinforced concrete hollow piles. Background technique [0002] The applicant has two invention patents: one is "prestressed reinforced concrete circular hollow pile with internal meshing structure", patent number: 201020188071.6; the other is "prestressed reinforced concrete rectangular hollow pile with internal meshing structure and Its processing method”, patent number: 201010170582.X, both of the two invention patents provide a structure with an internal thread on the inner wall of the central cylindrical hole penetrating the axial direction of the pile body, so that the building cap extends downward with part of the reinforced concrete and the prefabricated The central cylindrical hole of the stressed reinforced concrete hollow pile has a strong binding force, which effectively solves the problem that the reinforced ...
