Detailed description of the invention
The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.
As illustrated in figures 3-6, the welding heat-exchanger positioner of a kind of multi-angle nozzle arrangement described in the utility model, the fixed mount 6, journal stirrup locating rack 7, the flange locating rack 8 that comprise base plate 5 and be fixedly mounted on base plate 5, described base plate 5 is also provided with some ozzle positioning seats 1, position difference corresponding ozzle a903, the ozzle b905 of ozzle positioning seat 1 and the position at ozzle c907 place.
Described ozzle positioning seat 1 comprises positioning disk 101, axle 102 and support plate 104, support plate 104 is fixedly installed on base plate 5, support plate 104 top is provided with through hole, axle 102 and positioning disk 101 adopt parts processing, axle 102 is installed in the through hole on support plate 104 top, positioning disk 101 is arranged on axle 102 and holds greatly, and support plate 104 top is provided with housing screw 103, for holding down mandrel 102; Adopt the matched in clearance of H7/f7 between described axle 102 and support plate 104 upper through-hole, so that axle 102 can slide freely in through-holes, facilitate the position of positioning disk 101 to adjust.
As shown in Figure 5, Figure 6, for ensure axle 2 is connected with positioning disk 1 after axiality, namely guarantee locate ozzle be connected with axle 2 between axiality, to be coordinated with C face by A face between axle 2 with positioning disk 1 and lead, B face and D face are threaded connection; At A face and guiding place, C face, the small―gap suture of H7/f6 is adopted to coordinate.
The ozzle that positioning disk 101 size of each ozzle positioning seat 1 is corresponding according to its position is determined, positioning disk 101 towards by both direction Angle ambiguity, one is the angle in horizontal direction, decided by the installation of support plate 104 on base plate 5, two is the angles on vertical direction, is decided by the angle of inclination of support plate 104 upper through-hole in the vertical direction.Support plate 104 setting angle in the horizontal direction is easily guaranteed, the angle of inclination of support plate 104 upper through-hole in the vertical direction also easily ensures, then adjust by the axial location of adjustment axle 102 in support plate 104 upper through-hole in axle 102 position axially, and by housing screw 103 positioning and locking, ensure that the clamping position precision of each ozzle.
And be directly connected by positioning disk 101 mode positioned with ozzle, larger welding space is had when ozzle is welded, symmetrical tack weld can be increased to more than 12, the symmetrical weld seam being equivalent to weld increases, welding position is heated more even, welding deformation reduces, thus meets the requirement that heat exchanger linear dimension change ± 1mm scope, Angular Dimension change ± 30 ＇ scopes are newly ground in guarantee; Meanwhile, for ensureing tack welding space, axle 102 diameter is only about 60mm, support plate 104 width of support mandrel 102 is only about 150mm, also reserve larger space to tack welding, so that increase more symmetrical tack weld, be conducive to controlling welding deformation.
During clamping, the heat exchanger 9 drawing place shown in Fig. 1 is faced down, is placed on base plate 5, positioning lug 901 is connected with journal stirrup locating rack 7, realize location; Meanwhile, install journal stirrup 910 be connected four with the pin of four on fixed mount 6, meanwhile, flange 908 and flange locating rack 8 are located by connecting, and tighten fixing by the lock-screw of fixed mount 6 top and both sides, lower end, complete the location of heat exchanger core 909 and fix; Again the ozzle positioning seat 1 in left side in ozzle a903, ozzle b905, ozzle c907 respectively corresponding diagram 4, the ozzle positioning seat 1 of upper end are connected respectively with the positioning disk 101 of the ozzle positioning seat 1 on right side, unclamp housing screw 103, the axial location of adjustment axle 102, positioning disk 101 is connected with each ozzle respectively put in place, make each ozzle contact with the pipeline junction at its place simultaneously, housing screw 103 is tightened fixing, completes the positioning and clamping of heat exchanger 9 and this positioner.After positioning welding is implemented to each ozzle and pipeline enclosure, then heat exchanger 9 is unloaded from apparatus for tack-welding, be welded with the place not having to weld, can welding be completed.
For ensureing position dimension during product clamping, when clamping, positioning disk 101 coordinates with also adopting H7/f7 small―gap suture between ozzle, while clamping precision is high, is also convenient to the loading, unloading of part.
After above-mentioned all tolerances are cumulative, are no more than 1/3 of product tolerance, can ensure the position dimension requirement of product.
In applicability, this apparatus structure is simple, and intensity is enough, and only need introduce through simple, operator just can grasp its hints on operation; Axle 102 and positioning disk 101 adopt parts processing, and weight saving is to about 3kg, and it is handy that operator can accomplish.
