Abstract
The utility model relates to a cylinder welding central pressing assembly which comprises a central bolt, a central nut, a central spring and a pressing cone, wherein the central bolt is connected on a central position of a rotating table, the central spring is connected on the central bolt in a sleeve mode, the pressing cone is connected on the central bolt in a sleeve mode, the central nut is connected with the central bolt in a screw mode to enable the pressing cone to press the central spring in an elastic mode, and a conical surface of the pressing cone leans against more than three units of movable supporting assemblies. The central pressing assembly is adopted to drive movable rod supporting assemblies to lean against a fixed cylinder body workpiece, and the rotating table which can rotate in a plane and in space supports the movable supporting assemblies and drives the cylinder body to rotate toward two directions, and therefore positioning welding of the cylinder body is achieved. The cylinder welding central pressing assembly is simple in structure, convenient to operate, low in cost, and good in welding effect, and the welded workpiece is difficult to deform.
Description
Technical field
The utility model relates to a kind of welding tooling, relates in particular to a kind of distortion-free center pressing assembly of cylindrical parts workpiece welding that is applicable to.
Background technology
Development along with China's wind generating technology, increasing megawatt-grade high-power wind-driven generator puts into effect, can be in time cooling 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 that cylinder and square body deflection difference under the effect of welding heat source is obvious, existing frock is difficult to its achieve effective control, cause original assembly relation to break in welding process, integral solder distortion simultaneously 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, service life is low.
Summary of the invention
In order to overcome many defectives that in prior art, the welding anti-deformation tool exists, the purpose of this utility model is to provide a kind of simple in structure, and the workpiece fixing-stable can effectively limit the workpiece welding deformation, guarantees the cylinder welding center pressing assembly of automatic welding quality.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of cylinder welding center pressing assembly, it is characterized in that 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 centre bolt, the pressing cone is socketed on 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.
The utility model 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.

In figure, positioner 1, jointed shaft 2, turntable 3, supporting plate 4, centre bolt 5, central spring 6, pressing cone 7, center nut 8, motion bar bracing frame 9, support spring 10, motion bar 11, cylinder 12, square body 13.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Cylinder welding shown in Figure 1 center pressing assembly example structure schematic diagram, figure comprises turntable 3, supporting plate 4, centre bolt 5, central spring 6, pressing cone 7, center nut 8, motion bar bracing frame 9, support spring 10 and motion bar 11.Turntable 3 is provided with the centre bolt 5 perpendicular to rotary table top, three are around centre bolt 5 circumference uniform distributions on turntable 3 with mounting plate 4, on each supporting plate 4 all through motion bar bracing frame 9 movable support bars 11, be socketed with on motion bar 11 support spring 10 make motion bar 11 be in motion bar bracing frame 9 to centre bolt near or away from state; Be socketed with central spring 6 and pressing cone 7 on centre bolt 5, central spring 6 bottom pressing turntables 3, pressing cone 7 screws centre bolt 5 pressing central spring 6 tops through center nut 8, and the male cone (strobilus masculinus) of pressing cone 7 is with the inner of motion bar 11 and contacts or released state.
Shown in Figure 2, turntable 3 bottom center are movably hinged in being turntable 3 on positioner 1 fixing around jointed shaft 2 rotation in vertical and level scope through jointed shaft 2.cylinder 12 is placed on turntable 3 table tops, cylinder 12 round mouths below and turntable 3 upper surfaces be close to, pivot nut 8 descends pressing cone 7, pressing cone 7 pressing central spring 6, the male cone (strobilus masculinus) of pressing cone 7 holds out against motion bar 11 the inners makes motion bar 11 protruding on motion bar bracing frame 9, the outer end of motion bar 11 and cylinder 12 inwalls fit, motion bar 11 more than three is circumferencial direction cylinder 12 inwalls is held out against, by bonding machine to cylinder 12 and square body 13 full welds, by regulating the speed of turntable 3, can realize automatic welding, the rotation turntable is adjusted to the best with the welding position of required weldment, convenient welding, improve speed of welding.
