The specific embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is elaborated, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
As shown in Figure 2, weld jig for filter mounting of the present utility model, comprise backstay 1, be arranged on the movable fixture on positioning table 2 and second end relative with first end that is arranged on backstay 1 of first end of backstay 1, wherein, offer three locating slots 21 for the support bar 51 of Fixed-Filter support 5 on positioning table 2.
Because filter mounting 5 is the three-legged support structure, to be made by three support bars 51, top installation sheet 53 welding that are positioned at the bottom annulus 52 of three support bar 51 lower ends and are positioned at three support bar 51 upper ends, for fear of produce relative displacement between each parts in the process of welding, need three support bars 51, bottom annulus 52 and top installation sheet 53 are positioned.When using the weld jig for filter mounting of the present utility model, first bottom annulus 52 is enclosed within on positioning table 2 bottom annulus 52 is fixed, then the lower end of three support bars 51 of filter mounting 5 is inserted in three corresponding locating slots 21; Then top installation sheet 53 is enclosed within on backstay 1, the position of adjustment activity fixture on backstay 1 makes the top of three support bars 51 draw the lower surface that relies on top installation sheet 53 in, fix movable fixture, thereby complete the location to each parts, and then carry out welding operation.Therefore can guarantee can not produce relative displacement between each parts in welding process by the utility model, and then guarantee the machining accuracy of filter mounting 5, and can guarantee the uniformity of bulk article, can improve product percent of pass.In addition, but the utility model convenient operation personnel simple in structure be familiar with understanding, can improve the welding operating efficiency.
As shown in Figure 1 and Figure 2, in this preferred embodiment, positioning table 2 is truncated cone-shaped, and the diameter of positioning table 2 is less than or equal to the internal diameter of the bottom annulus 52 of filter mounting 5.When bottom annulus 52 is positioned, only need bottom annulus 52 directly is enclosed within on the positioning table 2 of truncated cone-shaped, make the better effects if of location.During practical application, the diameter of positioning table 2 only needs to be set to substantially equate with the internal diameter of bottom annulus 52, locating effect the best.And the positioning table 2 of truncated cone-shaped is easier to processing.
In this preferred embodiment, for successfully inserting locating slot 21 in the lower end that makes three support bars 51, three locating slots 21 can be set to extend along the axial direction of positioning table 2 to be offered, and, three locating slots 21 are wider than the width of three support bars 51 on bottom annulus 52 at the circumferential slot on positioning table 2, and during practical application, the lower end that can reach three support bars 51 is when the interior ring of bottom annulus 52 on being enclosed within positioning table 2 directly contacts, best results is more conducive to follow-up welding operation.In addition, consistent for the angle of inclination that guarantees three support bars 51, three locating slots 21 are set to upwards evenly distribute in the week of positioning table 2, and backstay 51 is vertically fixed on the center of positioning table 2; Setting also can guarantee like this, and top installation sheet 53 is parallel with bottom annulus 52.
In this preferred embodiment, the diameter of the second end of backstay 1 is set to be less than or equal to the interior ring through-hole diameter of the top installation sheet 53 of filter mounting 5, can be convenient to top installation sheet 53 and be enclosed within smoothly on backstay 1, thereby the radial position of top installation sheet 53 is positioned.Correspondingly, as shown in Figure 1 and Figure 2, be set to two setscrew nuts at the movable fixture of backstay 1 second end, can limit the axial location of top installation sheet 53.Directly stressed and easy damage of top installation sheet 53 when preventing screwed in place nut 3, when the height of regulating two setscrew nuts 3 arrives the good filter support 5 of clamping, the setscrew nut 3 of below contacts with top installation sheet 53 upper surfaces, tighten the setscrew nut 3 of top, the setscrew nut 3 that directly contacts with top installation sheet 53 is as bolster, to reduce the damage effect to filter mounting 5.
To sum up, use the weld jig for filter mounting of the present utility model, first filter mounting is fixed clamping, carry out again welding operation, each building block of localization filter support exactly, and then guarantee that three calcaneus branches strut slopes equate, and be evenly distributed on top installation sheet and bottom annulus, the top installation sheet is parallel with the bottom annulus simultaneously, can guarantee the machining accuracy of filter mounting.In addition, can according to the welding requirements of the filter mounting that adapts to differing heights, make the scope of application of the present utility model wider by movable fixture.And of the present utility model is simple in structure, can be easy to produce and operation, can enhance productivity.
The above is only preferred embodiment of the present utility model, is not limited to the utility model, and for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
