Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The embodiment is as follows:

as shown in figures 1 and 2, the auxiliary device for welding the flange of the three-way pipe is mainly suitable for the T-shaped three-way pipe, supports the three-way pipe and the flange, facilitates smooth implementation of a welding process and facilitates subsequent welding quality inspection.

Three-way pipe flange welding auxiliary device includes bottom plate 1, and 1 upper portion of bottom plate is provided with first riser 2, second riser 3 and third riser 4 respectively, and first riser 2, second riser 3 and third riser 4 all with 1 vertical fixed connection of bottom plate. The first vertical plate 2 and the second vertical plate 3 are arranged in parallel, the third vertical plate 4 is arranged in a direction perpendicular to the first vertical plate 2, the positions of the three vertical plates are set by matching with a three-way pipe, and a certain distance is formed between the three vertical plates.

The first vertical plate 2, the second vertical plate 3 and the third vertical plate 4 are respectively connected with a supporting mechanism, and the three supporting mechanisms are arranged at the same height. The supporting mechanism includes bracing piece 5, bracing piece 5 passes the through-hole setting on the riser and can produce the displacement to the riser relatively, and is concrete, bracing piece 5 chooses for use the lead screw that takes the whorl, set up threaded through-hole on the riser, bracing piece 5 and riser screw hole are connected the cooperation, the two constitutes lead screw nut mechanism, in bracing piece 5 pivoted, can produce the straight line displacement, thereby adjust the shift position of positioning disk 7, adapt to the three-way pipe of different model lengths, and overall structure can adjust in a flexible way, satisfy the needs in the operation process.

The end part of the supporting rod 5 is connected with a rotating handle 6, so that the supporting rod 5 is convenient to twist.

The support rod 5 is rotatably connected with a positioning disc 7, two groups of positioning grooves 8 are formed in the positioning disc 7, each group is at least provided with two positioning grooves 8, specifically, internal threads are formed in the positioning grooves 8 and used for being connected with positioning bolts 12, and the positioning bolts 12 are equivalent to positioning pins and used for positioning and locking the flange 11 on the positioning disc 7.

In addition, the positioning grooves 8 can be provided with a plurality of groups according to the model of the three-way pipe flange of a production unit, each group of positioning grooves 8 corresponds to one product, a plurality of groups of positioning grooves 8 can be provided according to the product requirement of actual production, the model of the product is usually fixed, and the product is not required to be changed frequently. The positioning groove 8 is a circular groove, and can also be understood as a blind hole, the aperture and the position arrangement of the positioning groove 8 are matched with the position arrangement and the aperture of the positioning hole on the flange 11, so that the positioning bolt 12 is ensured to pass through the positioning hole of the flange 11 and be connected with the positioning groove 8 of the positioning disc, and the flange 11 is fixed on the positioning disc 7.

One end of the support rod 5 is fixedly connected with a connecting disc 9, the connecting disc 9 is rotatably connected with the positioning disc 7 through a bearing 10, and the bearing 10 is an angular contact ball bearing.

Utilize the utility model discloses the process of carrying out welding operation as follows:

adopt the utility model discloses before carrying out three-way pipe flange welding operation, preset the position of three positioning disk 7 to the straight tube length and the branch pipe length that accord with this model three-way pipe. Because the threaded connection of the lead screw of the support rod 5 has self-locking property, the position of the support rod 5 is fixed, and the positioning disc 7 cannot be displaced during operation.

Overlap three flange 11 respectively at the both ends of three-way pipe straight tube 13 and the one end of bleeder, select the positioning bolt 12 that is fit for treating the welded flange, then utilize positioning bolt 12 to connect two flanges at straight tube both ends respectively on the positioning disk of first riser 2 and second riser 3, with the flange fixed connection of bleeder on the positioning disk that third riser 5 corresponds, the three-way pipe is followed in step, because the external diameter of pipe is the same with the internal diameter in flange hole, the pipe just inserts in the flange hole, after three flange rigidity, the position of pipe is also corresponding fixed.

Then, the straight pipe 13 and the flanges at the two ends, the branch pipe and the flanges can be welded, the operable positions of the circumference of the pipe are welded, the lowest position is generally difficult to operate, the pipe can not be welded, and at the moment, the three-way pipe and the flanges are fixed.

Then, pull down the flange of bleeder from the positioning disk, rotate the twist grip of bracing piece on the third riser 4, move the positioning disk that will correspond backward, make bleeder one end free, then the positioning disk that corresponds on the first riser 2 of manual rotation or the second riser 3, three-way pipe and flange synchronous revolution, the high setting of riser guarantees that bleeder and flange can not touch the bottom plate when rotatory.

And rotating the position which is not welded to the upper part, and fixing the relative position because the three-way pipe and the flange are basically welded, and then, manually holding the three-way pipe and completing the welding of the final position. In addition, the quality of the weld at each location can be checked during the rotation.

Above-mentioned operation is a mode that the staff was commonly used in practical application, does not represent the adoption the utility model discloses only this operation mode, because of the utility model discloses the convenient adjustment of structure can be used according to the demand is nimble.
