Lathe dedicated for boring on pipe fittings flange

Abstract

The invention relates to a tube flange drill machine, which comprises support, mechanical transmitter, clamper, hydraulic system, and electric system, wherein it also comprises multi-axle power head with main axle box at the middle plate of support; a tower gear group on the transmission axle in main axle box with several active wheels on the transmission axle; several planet wheel symmetry distributed on the circumference of active wheels to mesh active wheels; several main axles on the planet wheels; the transmitter drives the main transmission axle via tower gear group to drive the main axles of planet wheels to rotate. The invention can process several holes at one time, with high efficiency and quality.

Description

technical field [0001] The invention relates to machine tool technology, in particular to a special machine tool equipment for drilling flanges of pipe fittings. Background technique [0002] Drilling machines commonly used in the pipe fitting flange drilling method of the prior art are such as: Z32K, Z3050, Z3080 radial drilling machines, and the flange holes are processed with a single hole of the drilling die. The processing method of the prior art has the following disadvantages: [0003] The clamping parts are clamped and loosened by manual operation, and the position must be corrected manually, which increases the labor intensity of the operator, and because this kind of processing, the combination of the drilling template and the workpiece is guaranteed by the operator's work experience and technology , so the position error of drilling is relatively difficult to guarantee, resulting in larger correction errors and increased auxiliary time. [0004] Since the existin...

Problems solved by technology

[0003] The clamping parts are clamped and loosened by manual operation, and the position must be corrected manually, which increases the labor intensity of the operator, and because this kind of processing, the combination of the drilling template and the workpiece is guaranteed by the operator's work experience and technology , so the position error of drilling is relatively difficult to guarantee, resulting in larger correction errors and increased auxiliary time

[0004] Since the existing technology is to process single holes sequentially, the rocker arm is moved to the position of another hole after one hole is completed. In this way, when the position is found, the drill bit collides with the drill sleeve, and the friction is serious, which is easy to wear the drill bit and the drill sleeve. Sets will reduce the lifespan and increase the auxiliary time when moving to find the correct position
