Description

kinds of panel part positioning welding anchor clamps

Technical Field

The invention belongs to the technical field of machining, and relates to a machining clamp for positioning welding (or manual argon arc welding) of plate parts or straight weld parts.

Background

The plate welding parts are mostly straight welding seam type parts, and the straight welding seam type parts comprise butt welding of cylindrical parts, butt welding of conical cylindrical parts, butt welding of flat plate parts and the like. Before argon arc welding is carried out on the parts, positioning welding must be carried out on the parts. At present, manual positioning welding is mostly adopted in our positioning welding. And many people are needed to carry out auxiliary operation in the welding process, as shown in a part (cylindrical part) in fig. 5, when the part is subjected to positioning welding, in addition to welding personnel, 2 auxiliary personnel are needed to hold two sides of the part with hands for butt joint, so that the welding operation of the welding personnel is facilitated. Because of unstable manual operation factors, the tack welding is often accompanied by overlarge staggered teeth or inaccurate positioning, so that the conditions of part scrapping, re-grinding, tack welding and the like are caused, the production efficiency is low, and the labor cost is high.

Disclosure of Invention

The invention aims to provide a clamp for positioning welding (or argon arc welding) of plate parts aiming at an exhaust casing, so that the part qualification rate and the production efficiency are improved.

The technical scheme adopted by the invention is as follows:

A tack welding jig for sheet material parts, comprising,

the positioning plate is provided with a notch, and the notch is arranged along the length direction of the positioning plate;

the pressure plate is positioned above the positioning plate, the end of the pressure plate is rotatably connected with the positioning plate, the other end of the pressure plate is detachably connected with the positioning plate, a through groove penetrating through the upper end surface and the lower end surface of the pressure plate is formed in the pressure plate, and the width of the through groove is larger than that of a notch in the positioning plate;

and the two spring push blocks are connected in the notch of the positioning plate in a sliding manner.

, the plate part positioning and welding clamp further comprises a bottom plate, the upper end face of the bottom plate is fixedly connected with the positioning plate, the lower end of the bottom plate is connected with the supporting shaft, and the lower end of the supporting shaft is connected with the base.

, the bottom plate is channel steel, the concave surface of the channel steel is vertically connected with the support shaft, and the outer plane of the channel steel is riveted with the positioning plate.

, a butterfly bolt is hinged in the inner concave surface of the bottom plate end.

And , the detachable connecting ends of the positioning plate and the pressure plate are provided with notches for fastening.

And , the pressure plate is rotatably connected with the positioning plate by tightening the bolt.

And , the plate part positioning welding fixture further comprises a connecting rod arranged in the notch of the positioning plate, the connecting rod penetrates through the two spring push blocks, two ends of the connecting rod are respectively connected with the positioning plate, a spring is further arranged on the connecting rod, and the spring is positioned between the spring push blocks and the positioning plate.

Compared with the existing welding mode, the invention has the advantages that:

1. the parts are clamped through the pressure plate and the positioning plate, so that welding personnel can complete welding operation by persons;

2. by additionally arranging the U-shaped notch on the positioning plate, the part can be directly subjected to manual argon arc welding on the clamp;

3. the welding quality and the production efficiency of parts are improved, and the production labor cost is saved.

Detailed Description

The technical solution of the present invention is further illustrated in below with reference to the drawings, but the scope of protection claimed is not limited to the above.

As shown in fig. 3, which is a schematic diagram of parts to be welded, in view of the fact that the parts are straight-seam thin-walled parts, the conventional tack welding (or argon arc welding) is based on manual butt welding by personnel and then tack welding (or argon arc welding) is performed. This results in inefficient improvement of the welding quality and production efficiency of the parts.

As shown in fig. 1 to 4, the plate part positioning welding fixture mainly comprises a base 1, a support shaft 2, a bottom plate 3, a pressure plate 4, a positioning plate 5, a tightening bolt 6, a spring push block 7 (2), a connecting rod 8 and a spring 9 (2). the base 1, the support shaft 2 and the bottom plate 3 are welded to form a support frame of the whole fixture, the shape of the base 1 is not particularly limited, on the premise of being capable of being stably placed on the ground, the rigidity of the support shaft 2 is required to be good, the bottom plate 3 selects a channel steel, the connection position of the support shaft 2 and the bottom plate 3 is required to be not tilted by a hanging part, the positioning plate 5 is fixed on the bottom plate 3 by a rivet, the pressure plate 4 is flat, a rectangular notch is arranged on the pressure plate for positioning welding operation groove, a round hole is connected with the positioning plate 5 and the bottom plate 3 by the tightening bolt 6, the round hole is opposite to the other end of the round hole, the round hole is provided with a opening, the concave end hinged on the bottom plate 3, the nut is loosened, then is rotatably moved out of the opening, then the pressure plate 4 is rotatably moved out of the opening, the pressure plate 4 is wound, the butterfly nut is tightly pressed by the positioning plate 4, the spring push block 7, the.
