Oil pipe automatic conveying device

Abstract

The invention relates to the technical field of mechanical processing, and belongs to auxiliary equipment of machine tools, in particular to an automatic delivery device for oil pipes. The device is composed of five parts: walking beam device, central beam device, driving wheel device, driven wheel device and detection device; the combination of five parts realizes automatic turning in and out of long tube parts, automatic feeding out When feeding and feeding, enter from the rear end of the machine tool spindle at high speed, decelerate rapidly when approaching the positioning device, and stop after triggering the switch; exit the machine tool spindle at high speed when discharging, decelerate and stop rapidly when approaching the turning position, and hang out of the machine tool spindle when the workpiece rotates Some parts perform functions such as slewing support, pressure wheel floating and pressing, and material blocking.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, and belongs to auxiliary equipment of machine tools, in particular to an automatic delivery device for oil pipes. Background technique [0002] At present, the petroleum machinery industry generally uses CNC pipe thread lathes to process API oil and casing end threads, because the length of the pipe body is generally 4.88 meters to 12 meters, which is far greater than the distance between the two chucks of the machine tool spindle by about 2 meters, so Auxiliary equipment must be used to realize the automatic turning in and out of the machine tool for the pipe body, automatic feeding and discharging, high-speed entry into the main machine when feeding, and rapid deceleration when approaching the positioning device; high-speed exit from the main machine when discharging, and rapid deceleration when approaching the turning position. Functions such as workpiece rotation support hanging...

Problems solved by technology

Some large-scale steel pipe manufacturing enterprises use imported lathes and auxiliary equipment. The auxiliary equipment is fully functional and can be adjusted automatically, with the highest efficiency, but the price is expensive, which is difficult for small and medium-sized enterprises to afford.

General enterprises use self-made simple feeders, which can only realize part of the above functions. The price is cheap, but the function is single, the control accuracy is not high, and it is difficult to ensure product accuracy and quality.

Small and medium-sized enterprises usually use the cylinder to pull the connecting rod to drive the sloping plate to stand up or lay flat to turn over the material. This way of turning over the material has discontinuous motion trajectory, unstable movement, loud noise, and easy bending and deformation of the pipe.

The feeding and discharging method adopts ordinary three-phase asynchronous motor to drive the V-shaped roller to drive the pipe fittings to feed or discharge after being decelerated by the reducer. Because the ordinary three-phase asynchronous motor cannot adjust the speed, the feeding and discharging can only be carried out at a fixed speed, and there is no high speed. The function of deceleration and positioning after approaching, the control method mostly adopts the simple and backward relay control method, the operator has high labor intensity, low efficiency and high failure rate
