Description
Technical field
The utility model relates to a kind of welding means for correcting, specifically a kind of closed guard gate's frame welding means for correcting, belongs to civil air defense projects safeguard production mounting technique field.
Background technology
Closed guard gate's skeleton is welded by the shaped steel such as channel-section steel, I-steel is assembled, current discovery is with panel welding process, easily distortion is produced because steel are heated, particularly local deformation, thus the morpheme size of closed guard gate's skeleton can be caused to occur deviation, reduce product quality, can product rejection be caused what is more.
Utility model content
For the problems referred to above, the problem that the utility model quasi-solution is determined be to provide a kind of scientific and reasonable for structure, easy to use and flexible, cost are low and closed guard gate's frame welding means for correcting of long service life.
For achieving the above object, the utility model is by the following technical solutions: a kind of closed guard gate's frame welding means for correcting, comprise positive tooth screw mandrel, anti-tooth screw mandrel, screw and tommy bar, the two ends of described screw are respectively equipped with positive silk tooth one and anti-silk tooth one, the screw one end at described positive silk tooth one place is supporting anti-tooth screw mandrel, the screw one end at described anti-silk tooth one place is supporting positive tooth screw mandrel, described positive silk tooth bar and described anti-silk tooth bar include end and the body of rod, bayonet socket is equipped with outside the end of described positive silk tooth bar and described anti-silk tooth bar, the body of rod of described positive silk tooth bar and described anti-silk tooth bar is respectively equipped with positive silk tooth two and anti-silk tooth two, described screw centre position is provided with a screwed hole, tommy bar is provided with in described screwed hole, described positive tooth screw mandrel, the axes coincide of described anti-tooth screw mandrel and bayonet socket.
The beneficial effects of the utility model: the utility model structural design advantages of simple, in use, the both sides shaped steel of closed guard gate's skeleton is buckled into positive tooth screw mandrel to be firmly connected with in the bayonet socket of anti-tooth screw mandrel, promote tommy bar and rotate screw, thus screw two terminal filament tooth is moved along two ends different directions, hold out against two ends shaped steel, and due to by positive tooth screw mandrel, the dead in line design of anti-tooth screw mandrel and bayonet socket, make it at grade, thus make shaped steel greatly reduce distortion in welding process, particularly local deformation, have scientific and reasonable for structure, easy to use and flexible, low and the feature of long service life of cost.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: the positive tooth screw mandrel of 1-, the anti-tooth screw mandrel of 2-, 3-screw, 4-tommy bar, anti-silk tooth one, the 7-end of 5-positive silk tooth one, 6-, the 8-body of rod, 9-bayonet socket, the anti-silk tooth two of 10-positive silk tooth two, 11-.
Detailed description of the invention
In order to make those skilled in the art person better understand the utility model scheme, below in conjunction with the accompanying drawing in the present embodiment, clear, complete description is carried out to the technical scheme in the utility model embodiment.
As shown in Figure 1, the utility model discloses a kind of closed guard gate's frame welding means for correcting, comprise positive tooth screw mandrel 1, anti-tooth screw mandrel 2, screw 3 and tommy bar 4, the two ends of described screw 3 are respectively equipped with positive silk tooth 1 and anti-silk tooth 1, screw 3 one end at positive silk tooth 1 place is supporting anti-tooth screw mandrel 2, screw 3 one end at anti-silk tooth 1 place is supporting positive tooth screw mandrel 1, positive silk tooth bar 1 and anti-silk tooth bar 2 include end 7 and the body of rod 8, bayonet socket 9 is equipped with outside the end 7 of positive silk tooth bar 1 and anti-silk tooth bar 2, the body of rod 8 of positive silk tooth bar 1 and anti-silk tooth bar 2 is respectively equipped with positive silk tooth 2 10 and anti-silk tooth 2 11, screw 3 centre position is provided with a screwed hole, tommy bar 4 is provided with in screwed hole, positive tooth screw mandrel 1, the axes coincide of anti-tooth screw mandrel 2 and bayonet socket 9.
The utility model structural design advantages of simple, in use, the both sides shaped steel of closed guard gate's skeleton is buckled into positive tooth screw mandrel 1 to be firmly connected with in the bayonet socket 9 of anti-tooth screw mandrel 2, promote tommy bar 4 and rotate screw 3, thus screw 3 liang of terminal filament teeth are moved along two ends different directions, hold out against two ends shaped steel, and due to by positive tooth screw mandrel 1, the dead in line design of anti-tooth screw mandrel 2 and bayonet socket 9, make it at grade, thus make shaped steel greatly reduce distortion in welding process, particularly local deformation, have scientific and reasonable for structure, easy to use and flexible, low and the feature of long service life of cost.
Obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all should belong to the scope of the utility model protection.
