A two-way positioning thin-walled welding fixture

Abstract

The invention discloses a bidirectional location thin-walled workpiece welding clamp. The bidirectional location thin-walled workpiece welding clamp comprises a body base, a clamping plate, overturnable locating blocks, small shafts, gaskets, push pins, expansion blocks, guide plates, stop pins, a conical body, a cover plate, a mandrel, a nut, a ventilation pipe, a locating plug, springs I, split pins, bolts I, springs II, screws I, screws II, bolts II and screws III. By means of the bidirectional location thin-walled workpiece welding clamp, location clearance can be effectively eliminated, welding deformation can be resisted, and a welding seam zone is prevented from metal oxidation; and due to the fact that a locating face can be overturned, a support ring can be welded to a tool, and the number of tools and tool replacement time are reduced. When the bidirectional location thin-walled workpiece welding clamp is used practically, the problems that welding deformation of the support ring is large, and dimensions and angles are out of tolerance are solved; tool cost is saved; labor intensity is lowered; the qualification rate of products is increased; and production efficiency is improved.

Description

technical field [0001] The invention relates to the field of welding of thin-walled parts, and in particular provides a two-way positioning thin-walled welding fixture. Background technique [0002] The support ring is a metal thin-walled part, which is welded by inner and outer rings. The inner ring is a "]"-shaped structure with a cone angle on the ring wall, and the outer ring is a cone. The inner and outer rings are welded after insertion. The weld is The upper and lower fillet welds are long and the welding stress is large. Because the inner and outer rings have cone angles, two sets of fixtures were originally needed to complete the upper and lower weld seams. The original fixture adopts the structure of end face and mandrel inner tube to locate the inner and outer rings. Because the inner and outer rings have a cone angle, the parts and the fixture are in line contact, and the positioning gap is large. Under the action of welding stress, the welding deformation is la...

Problems solved by technology

The original fixture adopts the end face and mandrel inner tube structure to locate the inner and outer rings. Because the inner and outer rings have cone angles, the parts and the fixture are in line contact, and the positioning gap is large. Under the action of welding stress, the welding deformation is large, making the support ring The size and angle are out of tolerance, the metal oxidation in the weld zone is serious, and the manufacturing pass rate of the support ring is extremely low
