Specific embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As shown in Figure 1 to Figure 2, a kind of Thin-wall cylindrical part weld seam support meanss described in the utility model, including base plate
1st, axle 2, hinge seat 3, swinging support block 6, cone 7, pull bar 8 and gland 9, the lower end of the axle 2 are arranged on base plate 1, on
End is connected with gland 9, and the hinge seat 3 is arranged on axle 2, and the swinging support block 6 passes through hinge axis 5 and torsion spring 4 and hinge
Seat 3 is connected, and the cone 7 is sleeved on axle 2, and the pull bar 8 is arranged on inside axle 2, and is connected with 2 cones 7 by bearing pin,
The pull bar 8 connects end and has also been connected through a screw thread band shoulder nut 11.Using support fixture described in the utility model, make
Used time, axle 2 is arranged on the center of base plate 1, size and Support Position according to Thin-wall cylindrical part will be hinged to be done 3 and be arranged on
On axle 2, and cone 7 and pull bar 8 are installed successively, the hinged seat that then Thin-wall cylindrical part 12 will be assembled from big end 14
3rd, cone 7 and pull bar 8 are covered, and the big end 14 of Thin-wall cylindrical part 12 is arranged in the locating slot 101 of base plate 1, will be pressed
Lid 9 is compressed the small end 13 of Thin-wall cylindrical part 12 by being screwed on axle 2；Spiral shell finally will be passed through with rank nut 11
Line is connected to the upper end of pull bar 8, then pull bar 8 is moved up and down band mantle by adjusting band rank nut 11 according to position while welding
Body 7 is moved up and down, and then promotes swinging support block 6 to be rotated around hinge axis 5, and is realized to thin wall cylinder in the presence of torsion spring 4
The support compression of shape part 12, completes the welding processing of Thin-wall cylindrical part 12.To be further ensured that part crudy, the pendulum
The dynamic outer face shape of support block 6 matches with the inwall of Thin-wall cylindrical part 12.
The gland 9 is connected by screw thread with axle 2.Avoid when pull bar 8 is moved up and down, gland 9 produces displacement and shadow
Ring support effect.
The upper end of the axle 2 is provided with back-up ring 10 between being located at band shoulder nut 11.Back-up ring 10 is used to be positioned at shoulder nut
The upper end of axle 2.
Be ensure support reliability, improve the welding quality of Thin-wall cylindrical part 12, the medial surface of the swinging support block 6 with
The lateral surface of cone 7 matches.I.e. in the rotation process of swinging support block 6, the outer conical surface phase of its medial surface and centrum 7
Match somebody with somebody.
For ease of installation and removal, the lower end of the axle 2 is provided with ring flange, and ring flange is fixed on into base plate by bolt
On 1.
Locating slot 101 is provided with the base plate 1.Locating slot 101 is used to position the big end 14 of Thin-wall cylindrical part 12, keeps away
Exempt from outer of the Thin-wall cylindrical part 12 during supporting welding or deform, and then improve product percent of pass.
