SUMMERY OF THE UTILITY MODEL

The utility model relates to a solve not enough among the prior art, disclose a SCR catalyst module grid welding frock, accurately press from both sides the dress in order to improve welding efficiency to the SCR catalyst module grid of equipment, realize the efficient production preparation of grid.

In order to realize the above purpose, the utility model relates to a technical scheme of SCR catalyst module grid welding frock is: an SCR catalyst module grid welding tool comprises a plurality of inner flat steels inserted in a transverse and vertical staggered mode and outer flat steels positioned on the peripheries of the inner flat steels and fixedly spot-welded, wherein the welding tool comprises a welding support bottom plate, a cross-shaped clamping groove is vertically arranged in the middle of the welding support bottom plate, four corners of the welding support bottom plate are provided with vertex angle limiting corner blocks, and an edge clamping groove is arranged between the vertex angle limiting corner blocks on the same side along the side length direction of the corner blocks; when the middle part of the inner flat steel is clamped in the cross-shaped clamping groove, the outer flat steel is clamped in the side part clamping groove and attached to the inner side of the vertex angle limiting angle block.

Furthermore, limit portion draw-in groove including being located the outer angle steel of outer band steel outside vertical position, the inboard perpendicular finger of outer band steel is to outside angle steel setting inside dog, inside dog along outer band steel length direction interval arrangement have a plurality ofly.

Still further, an upper guide angle is arranged on one side, close to the adjacent outer angle steel, of the inner stop block.

Furthermore, the side bayonet of the cross-shaped clamping groove vertically points to the middle part of the outer angle steel, and the two sides of the middle part of the outer angle steel are symmetrically provided with inner stop blocks.

The technical effects of the utility model reside in that: in welding process, the operation workman only need the inside and outside band steel of the good slot of processing, according to the utility model discloses the back is put to the fixed station on the welding frock, by the welding operation workman directly carry on spot welding operation on next step can spot welding position in the handing-over department of inside and outside band steel, the frame week department of SCR catalyst module grid promptly. The utility model discloses realize the accurate location to SCR catalyst module grid among the SCR catalyst module grid welding process to cross draw-in groove, the spacing hornblock of apex angle are two location benchmarks. And the assembled SCR catalyst module grating is accurately clamped to improve the welding efficiency, so that the efficient production and manufacturing of the grating are realized.

Detailed Description

In order to more vividly explain the concrete implementation steps of the present invention, the following further description will be made with reference to the accompanying drawings:

an SCR catalyst module grid welding tool comprises a plurality of inner flat steels a inserted in a transverse-vertical staggered manner and outer flat steels b positioned on the peripheries of the inner flat steels a and fixedly spot-welded, the welding tool comprises a welding supporting bottom plate 1, a cross-shaped clamping groove 2 is vertically arranged at the middle position on the welding supporting bottom plate 1, vertex angle limiting corner blocks 3 are arranged at four corners of the welding supporting bottom plate 1, and an edge clamping groove 4 is arranged between the vertex angle limiting corner blocks 3 on the same side along the side length direction; when the middle part of the inner flat steel a is clamped in the cross-shaped clamping groove 2, the outer flat steel b is clamped in the edge clamping groove 4 and is attached to the inner side of the vertex angle limiting angle block 3.

Referring to fig. 1, the SCR catalyst module grid, which is an object to be treated according to the present invention, includes an inner flat steel a and an outer flat steel b. Referring to fig. 2 and 3, in welding process, the operation workman only needs to process the inside and outside band steel a, b of slot according to the utility model discloses the back is put to the fixed station on the welding frock, by the welding operation workman directly carry on next step spot welding operation can, refer to fig. 1 again, the spot welding position is located the handing-over department of inside and outside band steel a, b, the frame week department of SCR catalyst module grid promptly. The utility model discloses realize the accurate location to SCR catalyst module grid among the SCR catalyst module grid welding process to cross draw-in groove 2, the spacing hornblock 3 of apex angle are two location benchmarks.
