The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, this is preferred embodiment of the present utility model.
See Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of fixture type movable jig frame, comprise fixed body 1, described fixed body 1 marginating compartment fastens at least two floating holders 2, each described floating holder 2 comprises a clasp 21, described clasp 21 1 hook arms wear and are bolted with a tight fixed bolt 22, and described floating holder 2 is fastened on fixed body 1 edge by described clasp 21.
Fixed body 1 described in the utility model by the actual requirement shape of workpiece make and predetermined fixed in the construction site.In the course of the work, will treat that assembled components 3 splicing is good and be tiled on the described fixed body 1, more described clasp 21 will be fastened on the edge that assembly 3 and fixed body 1 are fitted, and make assembly 3 and fixed body 1 edge all stretch into described clasp 21; Tighten described tight fixed bolt 22, when tight fixed bolt 22 lower ends compress described assembly 3 surfaces, then clasp 21 rises because of tight fixed bolt 22 turns rotation under threaded function, make clasp 21 be close to described fixed body 1 away from a hook arm of described tight fixed bolt 22, tight fixed bolt 22 lower ends are tight against described assembly 3, thus clamp assembly 3; Fix a floating holder 2 at a certain distance, then each is fixed in fixed body 1 with assembly 3, clamp all floating holders 2 successively, all component 3 promptly all is fixed in fixed body 1, can implement welding assembly; In the assembling process, when causing assembly 3 position out-of-size scopes, then oppositely turn the tight fixed bolt 22 of the floating holder 2 of deformation direction because of welding contraction distortion, unclamp respective activity anchor clamps 2, discharge welding stress, tighten tight fixed bolt 22 again, retighten assembly 3, continue welding assembly; Circulation is finished until assembly 3 welding assemblies according to this; Then can unclamp all floating holders 2, take off workpiece from fixed body 1.
Wherein, when described floating holder 2 fastens, can make the described fixed body of described tight fixed bolt 22 lower end contacts 1 surface yet, and make clasp 21 be close to described assembly 3 away from a hook arm of described tight fixed bolt 22, this does not influence result of use of the present utility model.
The utility model is simple in structure, and is easy to operate, discharges welding stress by the degree of tightness of regulating floating holder 2, eliminates welding deformation, improves the steel construction assembling quality.Can not lose assembly 3 and fixed body 1 during simultaneously described floating holder 2 clamp assemblies 3, help improving workpiece surface quality.Avoided workpiece and moulding bed are completely fixed, made workpiece under vertical retained situation, horizontal direction can freely be stretched, and discharges the welding stress in the workpiece manufacturing process at any time, guarantees to be out of shape in controlled range after the workpiece tread flaking.This fixture type movable jig frame easy operating of while, and can reuse.Compare with traditional moulding bed, not only significantly reduced the welding stress of workpiece inside and the distortion after the tread flaking, cut the damage of weld seam when also having removed fixing required welding of workpiece and moulding bed and workpiece tread flaking from workpiece.
Make the quality of product not only obtain strong guarantee and further raising, also reduced the workload in the manufacturing process to a great extent, made things convenient for site operation, improved production efficiency.
See Fig. 2 and shown in Figure 4, described fixed body 1 edge has outwards extended the edge of a wing 11, and described floating holder 2 is fastened on the described edge of a wing 11.For guaranteeing the bearing capacity and the structural strength of moulding bed, fixed body 1 edge thickness is often thicker, then for the A/F that guarantees clasp 21 greater than fixed body 1 edge and assembly 3 edge thickness sums, so that assembly 3 can snap in described clasp 21 smoothly with fixed body 1 edge, described clasp 21 openings must be bigger, and this will influence clasp 21 structural strengths.So outwards extended the edge of a wing 11 at described fixed body 1 edge, the described edge of a wing 11 thinner thicknesses are convenient to reduce described clasp 21 A/Fs, improve clasp 21 structural strengths, improve dependability of the present utility model.
See shown in Figure 3ly, 11 bottom surfaces, the described edge of a wing are the plane, and described clasp 21 is the plane with the corresponding inner surface 211 in 11 bottom surfaces, the described edge of a wing.When so then clasp 21 hook arm inner surfaces 211 were fitted with 11 bottom surfaces, the described edge of a wing, the contact of formation face helped increasing contact friction, improves the clamping soundness of floating holder 2.
Wherein, described clasp 21 is " U " type, and clasp 21 inwalls are provided with anti-skidding line.At the bottom of " U " type clasp 21 hook arms and the hook is rounding off, and unstressed catastrophe point helps improving clasp 21 structural strengths, avoids clasp 21 to fracture; Clasp 21 inwalls are provided with anti-skidding line simultaneously, have further increased contact friction, have improved the clamping steadiness.
See shown in Figure 3ly, the end that described tight fixed bolt 22 stretches out described clasp 21 hook arms is provided with regulates spanner 23.Be convenient to turn described tight fixed bolt 22 like this, improved ease of use of the present utility model.
See shown in Figure 1ly, described fixed body 1 comprises the side bar 12 that constitutes fixed body 1 profile, and the described edge of a wing 11 extends in described side bar 12 outward flanges.
Described side bar 12 encloses and is fixedly connected with the brace summer 13 that is provided with at interval in length and breadth in the zone of covering, and described brace summer 13 ends are fixedly connected on side bar 12.
The above-mentioned fixed body of forming with side bar 12 and brace summer 13 1, reduced the material cost of fixed body 1, simultaneously because between side bar 12 and the brace summer 13 and be formed with the space between brace summer 13 and the brace summer 13, more help assembly 3 release welding stresses in the assembling process, help improving workpiece quality.
See shown in Figure 2ly, described fixed body 1 lower end convexes with the support column 14 that is used for fixing described fixed body 1.Described support column 14 is used for the ground built-in fitting affixed, thereby described fixed body 1 is fixed in the job site.
Should be noted that at last; above embodiment is only in order to the explanation the technical solution of the utility model; but not to the restriction of the utility model protection domain; although the utility model has been done to explain with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can make amendment or be equal to replacement the technical solution of the utility model, and not break away from the essence and the scope of technical solutions of the utility model.
