Embodiment 2

[0031] Such as figure 1 with figure 2 As shown, the difference between this embodiment and the first embodiment is that a rectangular positioning frame 7 is provided under the cross beam 2. The positioning frame 7 encloses the adjusting threaded rods 3 in the positioning frame 7. All corners are rounded corners 71 that match the outer contour of the adjusting threaded rod 3. Each adjusting threaded rod 3 is attached to the inner side of the four rounded corners 71 of the positioning frame 7; each rounded corner 71 is provided with a corner The locking device 8 corresponding to the circumferential locking of the adjusting screw rod 3.

[0032] Such as Image 6 As shown, the structure of each locking device 8 is: a pin hole is opened on the rounded corner 71, a positioning blind hole recessed inward is provided on the outer contour of the adjusting threaded rod 3 opposite to the pin hole, and a positioning pin shaft One end of 81 passes through the pin hole and then extends into ...

Embodiment 3

[0035] Such as Figure 4 As shown, the difference between this embodiment and the first or second embodiment is: in this embodiment, at least three upper fixed rods 41 are provided on the movable sliding sleeve 4, and each upper fixed rod 41 is along the circumference of the movable sliding sleeve 4. The upper fixing rods 41 are arranged at intervals in the direction, and each upper fixing rod 41 corresponds to the upper connecting rod 61 in each group of connecting rod groups one to one. The top of each upper fixing rod 41 is fixedly connected to the movable sliding sleeve 4, and the bottom of each upper fixing rod 41 is inclined downward Setting; the top of the upper connecting rod 61 in each connecting rod group is hingedly connected with the bottom of the corresponding upper fixing rod 41. At least three lower fixed rods 51 are provided on the fixed connecting sleeve 5, and each lower fixed rod 51 is spaced apart along the circumferential direction of the fixed connecting sl...

Abstract

The invention discloses a flange tube seat welding auxiliary tool. The flange tube seat welding auxiliary tool comprises a center rod, a cross beam and a central threaded handle, wherein the cross beam is a multi-arm cross beam which extends towards the periphery along the center of the cross beam and is provided with at least three stretching arms, a connecting through hole is formed in the center of the cross beam, the cross beam sleeves the center rod through the connecting through hole, a supporting device for supporting the cross beam above a tank body is arranged on the cross beam, and aconnecting threaded section matched with an inner threaded section of the central threaded handle is arranged on the upper section of the center rod; a movable sliding sleeve movably sleeves the center rod, a fixed connecting sleeve is fixedly arranged at the bottom of the center rod, and a connecting rod structure is arranged between the movable sliding sleeve and the fixed connecting sleeve. The tool is easy to carry and convenient to use, economical and efficient, and can be taken along with the use and safety in manufacturing production, and avoids the defect that the sealing surface of aflange needs secondary machining.

Description

Technical field [0001] The invention relates to a welding auxiliary tooling, in particular to a flange pipe seat welding auxiliary tooling. Background technique [0002] Flange is a very common connection part in mechanical equipment, which can be used for the connection between two shafts, the connection between two pipes, the connection between two equipment, etc., such as the tank mixing port in the mixing equipment It is connected to the external components through a flange, and the flange is welded to the tank mixing port through a pipe seat at the bottom of the flange. Since the mixing equipment has high requirements for the flatness of the sealing surface of the flange at the mixing port of the tank, conventional welding is easy to damage the flatness of the sealing surface of the flange, resulting in that the flatness of the sealing surface does not meet the standard. At present, after the flange welding is completed, secondary processing of the sealing surface is usuall...
