Tubular pile inner hole thread milling machine and tubular pile inner hole thread groove manufacturing method

Abstract

The invention discloses a tubular pile inner hole thread milling machine, and belongs to the field of building material machining equipment. The tubular pile inner hole thread milling machine comprises a support, a base, a spiral feeding mechanism, a cutter feeding device and a cutting knife; the base is movably installed on the support, and the cutter feeding device is fixedly connected with the base and controls the base to move longitudinally along the support; and the spiral feeding mechanism is installed on the base, the cutting knife is fixedly connected with the spiral feeding mechanism, and the spiral feeding mechanism controls a driving milling tool to advance or retreat along a tubular pile inner hole to conduct cutting. According to the tubular pile inner hole thread milling machine, the spiral feeding mechanism, the cutter feeding device and the cutting knife are combined, the thread depth and screw pitch reliability in the cutting process is guaranteed, the problem of drilling difficulty in the constructing process is solved, and the tubular pile bearing force is greatly reduced; and through adjustment of the spiral feeding mechanism, thread grooves with different screw pitches can be cut to meet different construction requirements. The invention further discloses a manufacturing method of a tubular pile inner hole thread groove.

Description

technical field [0001] The invention relates to an inner hole thread grinding machine, in particular to an inner hole thread grinding machine for pipe piles and a method for manufacturing thread grooves in the inner holes of pipe piles, belonging to the field of building material processing equipment. Background technique [0002] Pipe pile is a kind of concrete prefabricated engineering pile, which is mainly used in pile foundation engineering to improve the bearing capacity of foundation and foundation. The deficiencies of the prestressed concrete pipe piles poured by the existing centrifugal technology are poor soil affinity and low internal frictional resistance of the piles, that is, low bearing capacity. In order to meet the normal construction needs, in the prior art, a thread groove with a large pitch is cut on the inner diameter of the pipe pile to increase the side friction resistance of the pipe pile and realize the improvement of the bearing capacity. In the pri...

AI Technical Summary

Problems solved by technology

The deficiencies of the prestressed concrete pipe piles poured by the existing centrifugal technology are poor soil affinity and low friction resistance inside the pile, that is, low bearing capacity.

In the prior art, the thread groove processing process of the inner hole of the pipe pile is cumbersome, the preparation efficiency is low, and the thread grooves processed are of different depths and cannot meet the normal use needs
