Abstract
The invention discloses a steel pipe and flange welding and positioning tool. The tool comprises a rotating shaft and a supporting part, wherein the rotating shaft is arranged on a rotary position changing machine; a flange positioning device is arranged on the rotating shaft so that a flange rotates along the rotating shaft; and the supporting part is arranged on a machine frame of the rotary position changing machine, so that one end of a steel pipe is positioned in a flange central hole, the other end of the steel pipe is supported on the supporting part and the steel pipe and the flange are synchronously rotated. The flange and the steel pipe are conveniently positioned, fixed and rotated by the steel pipe and flange welding and positioning tool, and a welding component is not required to be handheld for fixing during welding, so that the production efficiency is obviously improved, and the welding quality is ensured.
Description
Technical field
The present invention relates to car tail-gas catalytic purifier and manufacture field, be specifically related to steel pipe flange welding positioning tool.
Background technology
Car tail-gas catalytic purifier is arranged on Exhuster of engine.Engine pan limited space, therefore catalytic cleaner assembly mostly is irregular, and this just causes in catalytic cleaner manufacture process, often needs to use various types of flange to carry out transition.Due to the specificity of car tail-gas catalytic purifier, existing flange welding device is impracticable for the welding of car tail-gas catalytic purifier.According to manual welding, weldment is more easy to operate, and weldment moves inconvenience, even if can weld reluctantly, has also had a strong impact on welding quality.
Summary of the invention
Problem to be solved by this invention is to provide steel pipe flange welding positioning tool, facilitates the location of flange and steel pipe, and is convenient to fixing and rotates, in addition during welding operation without the need to hand-held fixing weldment, significantly improve production efficiency, ensure welding quality.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme: steel pipe flange welding positioning tool, comprise the rotating shaft being located at and rotating on positioner, described rotating shaft is provided with flange positioner makes flange follow axis of rotation, also comprise the support portion being located at and rotating in positioner frame, steel pipe one end is positioned in flange center hole, and the other end is supported in synchronous axial system support portion realizing steel pipe and flange.Facilitate the location of flange and steel pipe, and be convenient to fixing and rotate, without the need to hand-held fixing weldment during welding operation.
Improve, described flange positioner comprises the outer rotary table be sleeved in rotating shaft and the inner rotary table being fixed on roller end, the flange pilot pin that described inner rotary table is provided with the eyelet on flange matches makes the relative inner rotary table circumference of flange locate, and described outer rotary table is provided with the position limiting structure making the relative inner rotary table axial location of flange near inner rotary table side.The circumferential and axial of flange are positioned.
Improve, described inner rotary table is fixed on roller end by axle head dog screw, and the head of screw of described axle head dog screw is less than the centre bore of flange.Being fixed on by inner rotary table in rotating shaft makes it follow axis of rotation.
Improve, be provided with spacing shim 7 between described axle head dog screw and inner rotary table, the diameter of described spacing shim is greater than pipe diameter and is not more than aperture, flange center hole.Make to be placed between the steel pipe in flange center hole and inner rotary table and form certain interval, when avoiding welding by flange and steel-pipe welding on inner rotary table.
Improve, described position limiting structure is the coupler body matched with flange, and the diameter of the minimum inscribed circle of described coupler body is less than the external diameter of a circle of flange.The axial location of flange is realized by the coupler body of outer rotary table.
Improve, described position limiting structure circumference is distributed on outer rotary table.
Improve, described outer rotary table is provided with handle.Be convenient to rotate outer rotary table.
Beneficial effect:
Adopt after technique scheme, this invention steel pipe flange welding positioning tool facilitates the location of flange and steel pipe, and is convenient to fixing and rotates, in addition during welding operation without the need to hand-held fixing weldment, significantly improve production efficiency, ensure welding quality.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
