Abstract
The utility model provides a welding holder, comprising a left valve, a left valve base, a right valve and a right valve base, while the flange ends of the left and right valve bases are both arranged with fixing blocks, wherein a left fixing block has a screw hole arranged with a left screw rod as left-handed rotation screw, while a right fixing block is relatively arranged with a through hole, a right screw rod via two common nuts is fixed on the right fixing block, the right screw rod has right-handed rotation screw, the left and the right screw rods are connected via a special nut with one left-handed rotation screw end connected with the left screw rod and one right-handed rotation end connected with the right screw rod, and at least three limit guide blocks are point welded around the object welded part. The utility model has the advantages of simple structure, little welding deformation, high parallelism between two planes of the left and right valve bases, high axiality of left and right valves and reliable sealing of valve.
Description
Affiliated technical field
The utility model relates to a kind of frock clamp, especially a kind of weld jig.
Background technology
At present for the telescopic joint of heavy caliber push-pull valve band bellows and the welding of right valve barrel, no special fixture, though adopt some measures to guarantee welding quality, as adopt the method for little electric current multilayer welding to reduce welding deformation, but because valve aperture, distortion is unavoidable, causes the axiality of the depth of parallelism on two planes of the left and right valve seat of valve and left and right sides valve body poor, causes valve seal not tight.
Summary of the invention
Be out of shape greatly when existing heavy caliber push-pull valve welds in order to overcome, the deficiency of the depth of parallelism on two planes of the left and right valve seat of valve and the axiality difference of left and right sides valve body, the utility model provides a kind of weld jig.
The technical scheme that its technical problem that solves the utility model adopts is a kind of weld jig, comprise left valve barrel, left valve seat, right valve barrel, right valve seat, the end face of flange of left valve seat and right valve seat all is equipped with fixed block, on the fixed block of the left side screwed hole is arranged, left screw rod is housed, and left screw flight is left-handed.The right fixed block correspondence position has through hole, right screw rod is fixed on the fixed block of the right by two plain nuts, and right screw flight is dextrorotation, and left screw rod connects by special nut with right screw rod, the threaded one end that special nut connects with left screw rod is left-handed, and an end that connects with right screw rod is dextrorotation; Around the position of need welding, also be welded with and be no less than 3 spacing guide pads.
The beneficial effects of the utility model are simple in structure, and welding deformation is little, the depth of parallelism on the left and right valve seat of valve two planes and the axiality height of left and right sides valve body, and valve seal is reliable.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural map of present embodiment;
Among the figure: 1. left valve barrel; 2. left valve seat; 3. fixed block; 4. left screw rod; 5. special nut; 6. right screw rod; 7. right valve seat; 8. spacing guide pad; 9. right valve barrel.
The specific embodiment
As shown in Figure 1, a kind of weld jig comprises left valve barrel 1, left valve seat 2, right valve barrel 9, right valve seat 7, and left valve seat 2 all is equipped with fixed block 3 with the end face of flange of right valve seat 7, on the left side fixed block 3 screwed hole is arranged, and left screw rod 4 is housed, and the screw thread of left screw rod 4 is left-handed.On the correspondence position of the right fixed block 3 through hole is arranged, right screw rod 6 is fixed on the fixed block 3 of the right by two plain nuts, the screw thread of right screw rod 6 is dextrorotation, left side screw rod 4 connects by special nut 5 with right screw rod 6, the threaded one end that special nut 5 connects with left screw rod 4 is left-handed, and an end that connects with right screw rod 6 is dextrorotation; Around the position of need welding, also be welded with and be no less than 3 spacing guide pads 8.Adjust the spacing of left valve seat 2 and right valve seat 7 by rotating special nut 5, guarantee the depth of parallelism on left valve seat 2 and 7 liang of planes of right valve seat, guarantee the axiality of left valve barrel 1 and right valve barrel 9 by spacing guide pad 8.The welding precision height.
Claims (1)
1, a kind of weld jig, comprise left valve barrel, left valve seat, right valve barrel, right valve seat, it is characterized in that: the end face of flange at described left valve seat and right valve seat all is equipped with fixed block, on the fixed block of the left side screwed hole is arranged, left screw rod is housed, left side screw flight is left-handed, the right fixed block correspondence position has through hole, right screw rod is fixed on the fixed block of the right by two plain nuts, right screw flight is dextrorotation, left side screw rod connects by special nut with right screw rod, and the threaded one end that special nut connects with left screw rod is left-handed, and an end that connects with right screw rod is dextrorotation; Around the position of need welding, also be welded with and be no less than 3 spacing guide pads.
