Abstract
The utility model belongs to the technical field of clamp equipment, in particular to a flanging flange welding positioning clamp, which comprises a positioning core, a positioning nut and a positioning bolt; the outer diameter of the positioning core is 0.5mm smaller than the inner diameters of a flanging hole and a flange of an oil tank seal, one end of the positioning bolt is welded on the inner side of the positioning core, the positioning nut is in threaded connection with the positioning bolt, and the outer end of the positioning nut is matched with the inner wall of the positioning core. The device meets the positioning effect of welding of the flanging hole and the flange on the end socket, reduces the welding difficulty of workers, and improves the welding precision and stability.
Description
Technical Field
The utility model belongs to the technical field of positioning fixture equipment, concretely relates to turn-ups flange welding position anchor clamps.
Background
The seal head of the pressure container needs to be connected with various pipelines, the connection of the seal head and the pipelines needs flanges for switching, and the seal head is generally welded with the flanges in a flanging mode in order to reduce stress concentration of products. The flange is limited by the small diameter of the flange, and the connection form generally adopts a single-side manual welding method. Because the position of the flange is strictly required, once the assembly of the flanging hole and the flange is completed, the flange and the flanging hole are not allowed to be dislocated during welding.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a turn-ups flange welding position anchor clamps to solve the problem that exists among the background art.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a turn-ups flange welding position anchor clamps which characterized in that: the positioning device comprises a positioning core, a positioning nut and a positioning bolt; the outer diameter of the positioning core is 0.5mm smaller than the inner diameters of a flanging hole and a flange of an oil tank seal, one end of the positioning bolt is welded on the inner side of the positioning core, the positioning nut is in threaded connection with the positioning bolt, and the outer end of the positioning nut is matched with the inner wall of the positioning core.
Preferably, the surface of the positioning core is provided with an arc-shaped cutting groove.
Compared with the prior art, the beneficial effects of the utility model are that:
the device meets the positioning effect of welding of the flanging hole and the flange on the end socket, reduces the welding difficulty of workers, and improves the welding precision and stability.
Drawings
FIG. 1 is a diagram illustrating the operation of the present invention;
fig. 2 is a top view of the present invention;
fig. 3 is an assembly view of the present invention and a flange.
Detailed Description
The following detailed description of the preferred embodiments of the present invention is provided in connection with the accompanying drawings. As shown in fig. 1-3, a flanging flange welding positioning fixture comprises a positioning core 1, a positioning nut 2 and a positioning bolt 3; the outer diameter of the positioning core is 0.5mm smaller than the inner diameters of the flanging hole 4 and the flange 5 of the oil tank seal, one end of the positioning bolt is welded on the inner side of the positioning core, the positioning nut is in threaded connection with the positioning bolt, and the outer end of the positioning nut is matched with the inner wall of the positioning core. The surface of the positioning core is provided with an arc-shaped cutting groove 6. The arc-shaped cutting groove is divided into a radial cutting groove and an axial cutting groove, the cutting groove in the axial direction is opened to the edge of the positioning core, and the purpose is that when the positioning nut is screwed, the positioning nut can deform the positioning core and extrude the flange on the outer side, so that the flange is fixed.
During welding, the flanging hole is firstly repaired by rolling, the flanging hole is butted with the flange, whether the flange can be normally matched is checked, and whether the distance from the top end of the flange to the lower end of the flanging hole is 152mm (for example, welding requires 150mm, and welding shrinkage of 2mm needs to be reserved) is checked. The flange and the flanging hole butt joint face are provided with grooves, the oil tank seal is required to be fixed on a positioner, the positioning core is inserted into the flanging hole of the flange and the oil tank seal, the positioning nut is screwed down, so that the positioning core is tightly attached to the flange, after the flanging hole of the oil tank seal is aligned to the flange, the spot welding of the flange and the flanging hole is completed, the positioning fixture is detached, and finally the manual welding work of the flange and the flanging hole is carried out.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
