Description

A kind of staircase and girder welds the template frock with the middle part contiguous block

Technical field

The utility model relates to a kind of welding template frock, particularly relate to a kind of staircase and girder and weld the template frock with the middle part contiguous block.

Background technology

At present, with methods such as tape measures contiguous block is measured the also method of spot welding assembly unit, can not satisfy contiguous block and make requirement for length dimension, step width, perpendicularity etc.; Every overlength staircase and girder all can have a lot of waypoints, just needs 4 pairs of contiguous block parts as 2 sections segmentations, because do not weld the template frock, the making welding efficiency is just very low, can not satisfy the manufacturing schedule needs at all; In addition, contiguous block thickness is big, and generally at 44mm, if do not have enough welded gaps with rectangular tube before welding, then weld strength, welding fusion character, through welding all can not reach welding requirements; Contiguous block is as the very important bearing structure strength member of staircase and girder medial section, if uniformity is poor, weld strength is not enough, can make in the middle of the overlength staircase and girder because other stress such as shearing force cause fatal problems such as fracture.

Therefore, design the assembly unit spot welding problem that effectively to solve at above-mentioned situation, guarantee that each position dimension, morpheme size meet the demands, increase constraint (restraint) degree and prevent that a kind of staircase and girder that welds distortion such as back material, parts from welding template frock, inventor's problem to be solved just with the middle part contiguous block.

The utility model content

The technical problem that the utility model mainly solves provides a kind of staircase and girder and welds the template frock with the middle part contiguous block, can effectively solve the problem of the assembly unit spot welding of middle part contiguous block, guarantee that effectively each position dimension, morpheme size meet the demands, increased constraint (restraint) degree and prevented from welding distortion such as back material, parts.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: provide a kind of staircase and girder to weld the template frock with the middle part contiguous block, this frock is the left-right symmetry structure, it comprises limited block, contiguous block, lining and rectangular tube, described rectangular tube two ends all are connected with lining, one side of described lining is connected with contiguous block, and the top of described contiguous block is provided with second limited block, and the arranged outside of described contiguous block has first limited block.

The beneficial effects of the utility model are: the utility model just can guarantee two linearity, profile width, step width between the contiguous block by after limited block, contiguous block, rectangular tube, lining are in place as requested; With the F folder each part and template are fixed together, can effectively guarantee position, the accuracy of gauge of weldment; Welding has clearly been reserved gap between contiguous block and the rectangular tube on the template, has been explicitly called for the lining installation requirement, prevents from not adding reasons such as lining, welded gaps are not enough and causes the weld defect problem that weld seam can't weld, welded gaps causes inadequately; Simultaneously, this welding template frock also is a kind of check template; If the model of contiguous block, rectangular tube, lining, size are not right, just can not assembly unit spot welding on template.
