Abstract
The utility model discloses a welding roller carrier which comprises a base as well as a driving and retarding mechanism, at least one group of left and right driving roller carriers, at least one group of left and right driven roller carriers and a control system which are arranged on the base, wherein the control system is electrically connected with the driving and retarding mechanism; each of the driving roller carriers and the driven roller carriers comprises rollers and two arc plates for mounting the rollers; each roller is arranged on the two arc plates through rotating shafts; and the driving and retarding mechanism synchronously drives driving rollers through a driving mechanism, a retarding mechanism and a driving mechanism. When the welding roller carrier is used for welding and flaw detection, workpieces rotate on the roller carrier and girth welding can be carried out as long as a welding gun is immovable; and radiographic inspection of patches can be carried out when the workpieces roll, and thus the welding production speed is increased, the welding quality is improved, the welding auxiliary time is greatly shortened, the labor intensity of workers is reduced, and the labor productivity is increased.
Description
Technical field
The utility model belongs to the special welding Aided Machine of the cylindrical workpieces such as pressure vessel, oil tank, pipeline, relate to specifically a kind of turning rolls, be widely used in the modern processing industries such as tubulation industry, pressure vessel manufacturing industry, metal structure welding processing industry, heavy-duty machinery manufacturing industry.
Background technology
In the cylindrical workpieces such as pressure vessel, oil tank, pipeline when welding,, workpiece need be organized, welding and butt welded seam are detected a flaw.The way that prior art adopts is to adopt traveling crane to put into row to coordinate, auxiliary work-piece be grouping, weld and the time of the cost of detecting a flaw long, labour intensity is high, production efficiency is low, causes simultaneously welding quality relatively poor.
The utility model content
The defective that exists for overcoming prior art, the utility model provides a kind of turning rolls, has assisted group short to, welding and flaw detection time, has reduced labour intensity, has improved production efficiency, and welding quality is high.
For achieving the above object, the technical scheme that adopts of the utility model is:
Turning rolls is characterized in that: comprise base and be arranged on the driving reducing gear on base, about at least one group active roller frame that arranges, about at least one group return idler frame, control system that arranges; Described control system is electrically connected to the driving reducing gear; Described active roller frame and return idler frame are equipped with roller; Drive reducing gear through driving mechanism, reducing gear, transmission mechanism driven in synchronism active roller.
Further, described active roller frame and return idler frame comprise that also described roller is arranged on two arcs through rotating shaft for two arcs that roller is installed.
Further, described transmission mechanism is worm and gear.
Further, described control system adopts the frequency converter electrodeless variable-speed to control.
Operation principle of the present utility model is adopt artificial or mechanical mode that workpiece is put between the roller of left and right, thereby the rotation of driving reducing gear drive active roller to make workpiece do driven rotation between roller.
Compared with prior art, the utlity model has following beneficial effect:
One, the utility model comprises base and is arranged on driving reducing gear on base, at least one group of left and right active roller frame, at least one group of left and right return idler frame, control system; Described control system is electrically connected to the driving reducing gear; Described active roller frame and return idler frame comprise roller and for two arcs that roller is installed, described roller is arranged on two arcs through rotating shaft; Described driving reducing gear drives active roller through driving mechanism, transmission mechanism, reducing gear and gear synchronous.Adopt artificial or mechanical mode that workpiece is put between the roller of left and right, make workpiece do driven rotation between roller thereby drive the rotation of reducing gear drive active roller; In welding, when flaw detection,, workpiece rotates on turning rolls, and welding gun is motionless just carries out girth welding; Workpiece rolls just can carry out the paster radiographic inspection; Also make welding quality high thereby improve the welding speed of production, greatly reduced welding non-cutting time, improve working environment, raised labour productivity.
Two, transmission mechanism of the present utility model adopts worm and gear, and gearratio is large, and bearing capacity is strong, can satisfy the operation requirements of the cylindrical workpieces such as large pressurized vessel, oil tank, pipeline.
Three, control system of the present utility model adopts the frequency converter electrodeless variable-speed to control, and has that speed adjustable range is large, precision is high, the characteristics of stability of rotation, make the utlity model has applied widely, practical.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Mark in figure: 1, roller, 2, transmission mechanism, 3, driving mechanism, 4, reducing gear, 5, base, 6 control systems, 7, arc.
The specific embodiment
The utility model will be further described below in conjunction with the drawings and the specific embodiments.
Turning rolls of the present utility model comprises base 5 and is arranged on driving reducing gear on base 5, at least one group of left and right active roller frame, at least one group of left and right return idler frame, control system 6; Control system 6 is electrically connected to the driving reducing gear; Active roller frame and return idler frame comprise roller 1 and for two arcs 7 that roller is installed, roller 1 is arranged on two arcs 7 through rotating shaft; Drive reducing gear through driving mechanism 3, reducing gear 4, transmission mechanism 2 driven in synchronism active rollers.
Drive reducing gear and be equipped with the hand-held remote control operating case, have simple to operate, reliable characteristics; Simultaneously, the hand-held remote control operating case is reserved the interlock interface, can conveniently realize interlock with equipment such as manipulator, welding machines, forms the automatic welding center.
As a kind of optimal way, transmission mechanism of the present utility model is worm and gear, and gearratio is large, and bearing capacity is strong, can satisfy the operation requirements of the cylindrical workpieces such as large pressurized vessel, oil tank, pipeline; Control system 6 adopts the frequency converter electrodeless variable-speeds to control, and has that speed adjustable range is large, precision is high, driving torque is large, and driving force is strong, the characteristics of stability of rotation; The utility model also is provided with axial direction positioning device on base 5, can prevent moving axially of workpiece processing time, the quality of raising group during to, welding and flaw detection operation.
The utility model adopts artificial or mechanical mode that workpiece is put between the roller of left and right, makes workpiece do driven rotation between roller thereby drive the rotation of reducing gear drive active roller; In welding, when flaw detection,, workpiece rotates on turning rolls, and welding gun is motionless just carries out girth welding; Workpiece rolls just can carry out the paster radiographic inspection; Improve the welding speed of production and also makes welding quality high, greatly reduced welding non-cutting time, improve working environment, raised labour productivity.
