Abstract
The utility model discloses a clamping apparatus and particularly provides a clamping apparatus used for variable cross-section manufacturing for small cross-section H-shaped steel, which can improve the processing efficiency. The clamping apparatus comprises an upper beam, a lower beam, a fixing bracket and a jack, wherein the fixing bracket consists of side supports at the two sides; a lower wing plate of the H-shaped steel is placed on the lower beam; and the jack is placed between a flange plate of the H-shaped steel and the upper beam of the fixing bracket. In the utility model, the H-shaped steel is clamped between the jack and the fixing bracket, and the height of the jack is adjusted so that the flange plate is tightly attached to a web plate, therefore, the gap does not need to be controlled by a welding accessory iron part, so that the time for welding can be reduced, and the jack and the fixing bracket cannot destroy the appearance of the H-shaped steel. The self adjusting distance of the jack is precise, therefore, the gap between the flange plate and the web plate can be controlled more accurately, and the subsequent welding can be more convenient.
Description
Technical field
The utility model relates to a kind of jig, especially a kind of jig that is used for the making of small bore H shaped steel variable cross-section.
Background technology
H shaped steel is to be made by welded flange plate and lower wing plate about the web of centre, in the manufacturing process of small bore H shaped steel, the top of web has a variable cross-section transition region that carries out the transition to small bore from the heavy in section, flange plate can be set to bending shape accordingly, since the bending degree of flange plate can not be fully and web top be complementary, just set up on the web will inevitably perk for flange plate, therefore just comparatively difficult when welded flange plate and web, influences process velocity.
When tradition is carried out the making of H shaped steel variable cross-section, generally be the auxiliary ironware of welding on H shaped steel, beat the gap that chock is adjusted variable cross-section place flange plate and web.After adjusted in the gap, chock was withdrawed from spot welding, knocks out ironware, the ironware weld of polishing again.Traditional method has following shortcoming: 1, the auxiliary ironware complex procedures of welding, and influence efficient, and after having made H shaped steel, must remove, also necessary polishing weld is not only lost time after the dismounting, also influences the outward appearance of H shaped steel.2, chock is regulated the gap and need be relied on making repeated attempts of operator, and this just makes efficient reduce.
The utility model content
Technical problem to be solved in the utility model provides a kind of jig that small bore H shaped steel variable cross-section is made that is used for that improves working (machining) efficiency.
The jig that is used for the making of small bore H shaped steel variable cross-section that its technical problem that solves the utility model adopts, comprise that the side by upper beam, underbeam and both sides supports fixed mount and the jack of forming, the lower wing plate of described H shaped steel is positioned on the underbeam, and described jack is positioned between the upper beam of the flange plate of H shaped steel and fixed mount.
Further be that the side of upper beam, underbeam and both sides supports and makes by the 25mm steel plate.
Further be that side is supported for Collapsible structure.
Further be that Collapsible structure is a helicitic texture.
The beneficial effects of the utility model are: it is middle to utilize jack and fixed mount that H shaped steel is clamped in, regulate the height of jack again, make flange plate and web be adjacent to, this just need not to weld auxiliary ironware and comes control gap, therefore can reduce the time of welding, jack and fixed mount also can not destroy the outward appearance of H shaped steel.The adjustable range of jack own is comparatively accurate, and is therefore more accurate when the gap of control flange plate and web, makes follow-up welding more convenient.The side of fixed mount supports can also be set to stretching structure, thereby adapts to dissimilar H shaped steel processing.
Description of drawings
Fig. 1 is a master map of the present utility model;
Fig. 2 is the right view of Fig. 1;
Parts, position and numbering among the figure: H shaped steel 1, fixed mount 2, jack 3, lower wing plate 11, web 12, flange plate 13, upper beam 21, side support 22, underbeam 23.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the utility model comprises that the side by upper beam 21, underbeam 23 and both sides supports 22 fixed mounts of forming 2 and jack 3, the lower wing plate 11 of described H shaped steel 1 is positioned on the underbeam 23, and described jack 3 is positioned between the upper beam 21 of the flange plate 13 of H shaped steel 1 and fixed mount 2.In use, at first a flange plate 13 and web 12 gapped parts are placed on the fixed mount 2, promptly are placed on the underbeam 23, again jack 3 is placed between flange plate 13 and the upper beam 21, jack 3 raises this moment, make the flange plate 13 and the web 12 of H shaped steel 1 be adjacent to, check every deviation, qualified errorless after, flange plate 13 and web 12 are carried out spot welding, after above-mentioned work is finished, unclamp jack 3 and withdraw from, take off fixed mount 2.Carry out whole welding of H shaped steel 1 variable cross-section place flange plate 13 and web 12 at last, thereby finish the processing and fabricating of H shaped steel 1.After adopting the utility model to make H shaped steel 1, just need not to weld auxiliary ironware, therefore both can reduce operation, also can avoid the outward appearance of H shaped steel 1 to be destroyed.Jack 3 is comparatively accurate when regulating height, and therefore, flange plate 13 is more accurate with cooperating of web 12, and H shaped steel 1 quality that processes also gets a promotion.
Fixed mount 2 can adopt square frame structure, puts the beams in place 21, the side of underbeam 23 and both sides supports 22 and make by the 25mm steel plate.Underbeam 23 has enough width to support H shaped steel 1.
In order to adapt to the H shaped steel 1 of different size, it is Collapsible structure that side supports 22.Just fixed mount 2 can support 22 by side and regulate height, thereby holds the H shaped steel 1 of different size, and it can be helicitic texture that side supports 22, regulates height by the rotation screw thread; Also can be hydraulic structure, control height by hydraulic pressure; Can be guide-tube structure also, fix the position by pin.Therefore, no matter adopt which kind of structure, all can adjust suitable height, thereby be convenient to process the H shaped steel 1 of different size before use according to the specification of H shaped steel 1.Certainly, in order to make the utility model simpler, Collapsible structure is a helicitic texture.
