(3) weld.
(4), after weld seam is cooling, rotate backward each power transmission group in thin-wall barrel of the present invention welding and school clamp with spannerThe power screw of part, and operate the guide pin of each guidance set in thin-wall barrel of the present invention welding and school clamp, make eachRise by piece to the motion of support ring center position, depart from thin-wall barrel inwall.
(5) thin-wall barrel welding of the present invention is sling with school clamp, take out the thin wall cylinder parts after welding.
2, for school shape
(1) thin-wall barrel welding of the present invention is sling with school clamp, put into and treat school shape thin wall cylinder parts inner chamber.
(2) rotate the power screw of each force transfer unit in thin-wall barrel of the present invention welding and school clamp with spanner, promoteRespectively rise by piece to the direction motion away from support ring center and contact with thin-wall barrel inwall, evenly or anisotropically inciting somebody to action by school shape requirementThin-wall barrel inwall is propped up.
(3) knock the support bulging face of thin-wall barrel with wooden mallet, make described shape face and thin-wall barrel of the present invention welding and school shapeThe piece laminating of rising of fixture.
(4), after school shape completes, rotate backward each power transmission group in thin-wall barrel of the present invention welding and school clamp with spannerThe power screw of part, and operate the guide pin of each guidance set in thin-wall barrel of the present invention welding and school clamp, make eachRise by piece to the motion of support ring center position, depart from thin-wall barrel inwall.
(5) thin-wall barrel welding of the present invention is sling with school clamp, take out the thin wall cylinder parts after the shape of school.
The beneficial effect of thin-wall barrel welding of the present invention and school clamp:
1, the highly versatile of thin-wall barrel welding of the present invention and school clamp, only needs be equipped with the power screw of different length and leadTo pin, just applicable to welding and the school shape of the thin wall cylinder parts of different inner cavity sizes.
2, thin-wall barrel welding of the present invention and school clamp both can be used for the welding of thin wall cylinder parts, can be used for again thin wall cylinderThe school shape of body part, thereby use face expands.
3, thin-wall barrel welding of the present invention and school clamp, the group mode of its piece that rises, guidance set and force transfer unit makesPower is only along the transfers of power screw, and it is consistent that two guide pins of power screw both sides stretch out direction, and the piece that rises can only be along oneIndividual direction stable motion, thus ensure thin wall cylinder parts to support the accuracy and the reliability that rise.
4, owing to being provided with step at guide pin free end, thus support rise by the time support amount of rising can be controlled in scope of design, and be convenient toKnow the regulated support amount of rising.
5, thin-wall barrel of the present invention welding is simple in structure, lightweight with school clamp, compared with traditional weld jig, heavyAmount has alleviated more than 50%, and manufacturing cost can reduce more than 50%.
6, thin-wall barrel welding of the present invention is easy to operate with school clamp, and only need rotate power screw with spanner can make the piece that risesEvenly or anisotropically thin-wall barrel inwall is propped up by welding requirements or school shape requirement, met the needs of welding or school shape; WeldingOr after school shape completes, the taking-up of described fixture is also very simple, convenient.
