Abstract
The invention relates to a bidirectional adjustable cylindrical welding anti-deformation fixture which comprises a rotary table, a central compressing component and more than three groups of movable supporting components, wherein the central compressing component is arranged on the rotary table, the rotary table is in a rotation state around the central compressing component, the more than three groups of movable supporting components are uniformly distributed on the rotary table around the central compressing component, and the central compressing component props against the more than three groups of movable supporting components so that the movable supporting components are simultaneously extended outwards or simultaneously retracted. According to the bidirectional adjustable cylindrical welding anti-deformation fixture disclosed by the invention, the central compressing component drives the movable supporting components to prop against and fix a cylinder workpiece, and the rotary table capable of rotating in plane and space drives the cylinder workpiece to rotate in two directions by supporting the movable supporting components so that the cylinder workpiece is located and welded; in addition, the bidirectional adjustable cylindrical welding anti-deformation fixture disclosed by the invention has the advantages of simple structure, convenience in operation, low cost and good welding effect; and the welded workpiece has less possibility of deformation.
Description
Technical field
The present invention relates to a kind of welding tooling, relate in particular to a kind of cylindrical parts workpiece that is applicable to and weld distortion-free twocouese adjustable tool.
Background technology
Development along with China's wind generating technology, increasing megawatt-grade high-power wind-driven generator puts into effect, can in time cool off in order to ensure the wind-driven generator distribute heat, generator is essential with cooling device, and the Backpack type hollow cooler occupies significant proportion therein.The cylindrical parts workpiece occupies very large ratio in the Backpack type hollow cooler, and the quality of cylindrical parts workpiece directly has influence on product quality.Consider the residing particular surroundings of wind-driven generator, the year-round operation circumstance of temperature difference is larger, the general manual argon arc welding that adopts connects, stability of the welding quality is poor, yield rate is low, by common bonding machine, can realize the freely-movable of welding gun phase butt welded seam, thereby realize the automatic welding of weld seam, but weldquality can't guarantee, mainly is that cylinder and square body deflection difference under the effect of welding heat source is obvious, and existing frock is difficult to its achieve effective control, cause original assembly relation to break in the welding process, simultaneously integral solder distortion causes weld seam and automatic welding gun apart from significant change, can't realize stable automatic welding, the final poor welding quality of product, operational reliability is low, and service life is low.
Summary of the invention
In order to overcome many defectives that the welding anti-deformation tool exists in the prior art, the purpose of this invention is to provide a kind of simple in structure, the workpiece fixing-stable can effectively limit the workpiece welding deformation, guarantees the adjustable cylindrical parts welding of the twocouese anti-deformation tool of automatic welding quality.
In order to achieve the above object, the technical solution used in the present invention is: a kind of twocouese is adjustable, and cylindrical parts welds anti-deformation tool, it is characterized in that comprising turntable, center pressing assembly and three groups of above movable supporting assemblies, center pressing assembly is arranged on the turntable, turntable is around center pressing assembly rotation status, three groups of above movable supporting assemblies are distributed on the turntable around center pressing assembly, and center pressing assembly pushes against three groups of above movable supporting assemblies makes the movable supporting assembly be simultaneously protruding or simultaneously inside indentation state.
Described movable supporting assembly comprises motion bar bracing frame, support spring and motion bar, motion bar is in support spring is actively supported on the motion bar bracing frame, the inner of motion bar pushes against center pressing assembly, the outer end of motion bar be to the direction indentation of motion bar bracing frame or dorsad motion bar bracing frame direction stretch out.
Described center pressing assembly comprises centre bolt, center nut, central spring and pressing cone, centre bolt is connected in the turntable center, central spring is socketed on the centre bolt, the pressing cone is socketed on the centre bolt, center nut screws centre bolt makes the pressing cone be elasticity pressing central spring state, and the conical surface of pressing cone pushes against three groups of above movable supporting assemblies.
Described turntable bottom is articulated on the positioner through jointed shaft, and turntable is space 360o rotation displacement stationary state around jointed shaft at positioner.
After adopting above technical scheme, the beneficial effect that the present invention reaches is: the pressing cone is presented at centre bolt, lower motion, the conical surface of pressing cone pushes against motion bar the inner, motion bar is in movable support frame under the support spring effect and stretches out and the indentation state, when stretch out the outer end of motion bar and workpiece cylinder inwall fit, the cylinder fixing-stable, energy establishment cylinder welding deformation when cylinder welding side body, restriction cylinder and square body weld seam butt-joint clearance and misalignment worsen, be conducive to welding stability and improve, argon-arc welding seam quality and parts global formation quality improve; Turntable can turn at its plane internal rotation, and turntable can be around jointed shaft space rotation on positioner, bidirectional rotary can make workpiece be adjusted to optimum welding position, be fit to the workpiece welding of all size, size, simultaneously can realize automatic rotary welding, guarantee that weld bead height, radian are consistent, need not polishing, greatly improved operating efficiency.
The present invention pushes against stationary cylinder body workpiece at the bottom of adopting pressing assembly in center to drive the motion bar supporting component, but and drive the cylinder bidirectional rotary by the turntable of plane and Space Rotating through the movable support supporting component, thereby realize the positioning welding of cylinder, it is simple in structure, easy to operate, cost is low, and welding work pieces is not yielding, and welding effect is good.
