DETAILED DESCRIPTION

[0021] The utility model discloses a kind of toolings for assisting breathing valve component welding, the following specific description is made to one embodiment of the utility model in conjunction with drawings.

[0022] As Figure 1 ​As shown in the figure, a tool for assisting the welding of a breathing valve component includes a tool body 1 and a plurality of legs 2. The tool body 1 is disc-shaped and includes a first wall 101 and a second wall 102. The first wall 101 is located on one side of the tool body 1, and the second wall 102 is located on the other side of the tool body 1. The first wall 101 includes a first positioning groove 3 in the shape of a cross and a plurality of second positioning grooves 4 in the shape of a ring. Each second positioning groove 4 is arranged concentrically along the radial direction of the tool body 1. The first positioning groove 3 is concentric with the second positioning grooves, and the first positioning groove 3 connects each second positioning groove 4.

[0023] As shown in the figure, Figure 2 the second wall 102 includes a third positioning groove 5 in the shape of a cross. The third positioning groove 5 is provided with a plurality of fixing grooves in the shape of a circle. The position of the third positioning groove 5 corresponds to the position of the first positioning groove 3. The first positioning groove 3 has a plurality of communication holes 6 that penetrate the third positioning groove 5, and the communication holes 6 are located at the junction of the first positioning groove 3 and the second positioning groove 4.

[0024] The tool body 1 has four threaded holes, each of which is located outside the second positioning groove 4. The end of each leg 2 has a stud that matches the threaded hole. The stud is threadedly connected to the threaded hole, and the end of each leg 2 is in contact with the first wall 101 or the second wall 102 of the tool body 1.

[0025] As shown in the figure, Figure 3 the worker uses the first wall 101 to assist in welding the guide device of the breathing valve. Each leg 2 is installed on one side of the second wall 102 so that the end surface of the leg 2 is in contact with the second wall 102. Each leg 2 supports the tool body 1, making it suspended. The guide device includes a first ring 7, a second ring 9, and a plurality of first strip steels 8. The outer diameter of the first ring 7 is smaller than the outer diameter of the second ring 9. During the welding operation, the first ring 7 is placed at the intersection of the first positioning groove 3, and the second ring 9 is placed in the second positioning groove 4 that matches it. Then, the first strip steel 8 is placed in the first positioning groove 3, with the inner end of the first strip steel 8 adjacent to the first ring 7 and the outer end adjacent to the second ring 9, facilitating the welding operation of the worker. If the guide device is stuck to the first wall 101 during welding, the worker can use a metal rod to insert it into the communication hole 6 from the second wall 102, push the guide device out, and separate it from the first wall 101.

[0026] As shown in the figure, Figure 4As shown, the worker uses the second wall surface 102 to assist in welding the cross support structure of the breathing valve, and installs each leg 2 on one side of the first wall surface 101, so that the end surface of the leg 2 is in contact with the first wall surface 101. The cross support structure comprises a third circular ring 10 and a support steel 11, and the support steel 11 is composed of a second strip steel and a fourth circular ring fixed at the end of the second strip steel. The worker places the third circular ring 10 at the intersection position of the third positioning groove 5, and then places the support steel 11 in the third positioning groove 5, and configures the fourth circular ring in the fixed groove. The inner end of the support steel 11 is adjacent to the third circular ring 10, which facilitates the worker to perform the welding operation. If the cross support structure is stuck with the second wall surface 102 during the welding process, the worker can use a metal rod to insert into the communication hole 6 from the first wall surface 101, and push the cross support structure out, so that it is separated from the second wall surface 102.
