Problems solved by technology

[0003] However, in the above-mentioned manual spot welding process, it is difficult for the operator to perform the welding operation alone. It is necessary to manually position the parts to be welded by manpower. The operator manually corrects the levelness and flatness of each beam at the weld, and another person performs the welding operation. , the human error caused by manual correction makes the positioning accuracy and welding accuracy far below the requirements

Embodiment 1

[0057] The invention provides a steel structure civil air defense door frame tailor-welding tooling, including: a frame, a fixed reference tooling 1 fixed on the frame, and a hand-held movable reference tooling 2; image 3 As shown, the fixed reference tooling 1 includes a workbench 11 and a number of movable fixing blocks 12 arranged on the workbench 11; the workbench 11 is provided with a corner chute 11a for positioning the frame frame beam 4 and a frame for positioning the frame. The spacing chute 11b at the position of the inner middle beam 3, the two movable fixed blocks 12 set in the corner chute 11a slide along the direction parallel to the chute, and the two thrusts act on the same bearing point, and the spacing chute 11b is perpendicular to the middle The beam 3 is arranged in parallel with the connecting line of the bearing points of the adjacent two corner chutes 11a;

[0058] The movable reference tooling 2 is used to set the limit of the short beam 5 in the close...

Embodiment 2

[0073] The difference from the first embodiment is that the directions of the two thrusts of the corner chute 11a are different, and other structures are the same, which will not be repeated here.

[0074] In a preferred embodiment of the present invention, as Image 6 As shown in the figure, the two thrusts of the corner chute 11a are parallel and collinear, and the corner chute 11a is set to be perpendicular to the diagonal structure, so that the movable fixed block 12 has two directions when sliding in the corner chute 11a. The component force drives the frame beam 4 to move toward the middle beam 3 on one side, and the two adjacent frame beams 4 on the other side approach and clamp each other, which improves the positioning accuracy of the frame beam 4 .

Embodiment 3

[0076] The invention also provides an application method of a steel structure civil air defense door frame tailor-welding tooling, comprising the following steps:

[0077] S1. Place a number of movable fixing blocks 12 in the corner chute 11a and spacing chute 11b of the point-fixed welding table, and adjust the spacing of each movable fixing block 12 in the spacing chute 11b according to the length of the short beam 5 in the skeleton, Press and rotate the locking part 123 so that the stop block at one end of the guide part 122 and the sliding surface of the guide part 122 clamp the table surface, and fix the moving fixing block 12 in the spacing chute 11b to complete the spacing chute 11b The positioning of the inner mobile fixed block 12;

[0078] S2, put the frame beam 4 and the middle beam 3 into the bearing portion 121 of the mobile fixing block 12 at the corresponding position, the frame beam 4 follows the guide portion 122 and slides along the corner chute 11a, and the ...

Abstract

The present invention relates to the technical field of welding tooling, in particular to a tailor-made welding tooling for a steel structure civil air defense door frame and its application method, including: a frame, a fixed reference tool fixed on the frame, and a hand-held movable reference tool; the fixed reference tool Including the workbench and a number of moving fixed blocks set on the workbench; the workbench is provided with corner chutes for positioning the framework frame frame beams and spacing chutes for positioning the position of the middle beam inside the framework, used for movable reference tooling The position limit of the short beam in the enclosed frame surrounded by the middle beam of the skeleton and the frame beam includes a positioning part placed on the side where spot welding has been completed, and a clamping part placed on the side where spot welding is required; the present invention Through the setting of the fixed reference tooling and the movable reference tooling, manual operation errors are avoided, the uniformity of the weld gap during the splicing process of the skeleton is ensured, and the positioning accuracy and welding accuracy of the beams in the skeleton are improved.

Description

technical field [0001] The invention relates to the technical field of welding tooling, in particular to a tailor-welding tooling for a skeleton of a steel structure civil air defense door and an application method thereof. Background technique [0002] Welding is a processing technology and connection method that produces atomic bonding between two workpieces by heating, pressurizing or both. Welding is widely used, both for metals and non-metals. In industrial production, due to the requirements of skeleton installation, the welding position accuracy between the horizontal and longitudinal beams of the skeleton is relatively high, so the process of positioning spot welding and then welding is adopted, and spot welding is carried out in the welding joint area. Temporary welding, so that the parts to be welded are installed firmly and avoid dislocation during welding. [0003] However, in the above-mentioned manual spot welding process, it is difficult for the operator to c...
