Ball screw jacking type automatic anti-flee wheel shelf

Abstract

The invention discloses a ball screw jacking type automatic anti-flee wheel shelf, which consists of four parts of a driving wheel shelf, a driven wheel shelf, a detector and an electronic control component, wherein the upper part of the driving wheel shelf is connected with a bearing seat, the middle part of a driving shaft is provided with a roller wheel, and the other end of the driving shaft is connected with a driving reducer which is connected with a rotary main motor by a flange assembly; two sides of the upper part of a driven base of the driven wheel shelf are equipped with a fixed seat through bolts, the rear end of a movable seat is connected with a ball screw lifter; a anti-flee motor reducing gear is connected with a ball screw reducer by a coupler; and the detector is provided with a displacement sensor and is fixed on the upper part of a micro-adjust mechanism by a bolt. The invention has the advantages of improved work efficiency, rapid reaction speed, ability of achieving real-time control, reduced equipment volume, energy conservation, reduced loss, long service life, higher reliability and the like.

Description

technical field [0001] The invention relates to a cylinder circular seam welding technology, in particular to a ball screw jacking type automatic anti-channeling roller frame. Background technique [0002] The anti-channeling roller frame can be widely used in cylindrical girth welding technologies such as pressure vessels, oil pipelines, nuclear power plants, and chemical industries; especially for girth welding of thick-walled narrow-gap butt joints and narrow-groove welded workpieces, it shows unique advantages , The welding seam can be kept at the same position through the ball screw jacking anti-channeling. The roller frame of the original product is connected to the roller seat by bolts on the base. Bearings are installed on the roller seat and there are rotating rollers, electric control box and a manual control box. The rotation of the cylinder can be realized by rotation; however, due to the roundness error of the workpiece during processing and the deviation of th...

AI Technical Summary

Problems solved by technology

The roller frame of the original product is connected to the roller seat by bolts on the base. Bearings are installed on the roller seat and there are rotating rollers, electric control box and a manual control box. The rotation of the cylinder can be realized by rotation; however, due to the roundness error of the workpiece during processing and the deviation of the placement position of the roller frame, there is a certain angle between the center line of the workpiece and the ideal center line deviation of the roller frame. It will cause the workpiece to advance along a certain helical line during the rotation process, that is, to move along the axial direction, and this kind of axial movement cannot be solved for the original roller frame, so it is impossible to perform good automatic welding and improve Work efficiency, which affects welding quality
