Problems solved by technology
Disadvantages: 1. Since the gap of the explosion-proof joint is very small, it can only be welded manually, and automatic welding by robots cannot be realized. The welding efficiency is very low, the cost is high, and the welding quality varies; 2. The welding point is located outside the side plate , affecting the aesthetics of the explosion-proof junction box

Embodiment Construction
[0032] refer to Figure 1-13 Shown, the explosion-proof junction box welding process of the present invention, the steps are as follows:
[0033] Step 1: Firstly assemble a base plate 1, a flange 2, and four side plates 3 with fixtures, and then fix them by spot welding at their local joints to form a preliminary explosion-proof junction box frame structure.
[0034] Step 2: An annular groove 5 is formed on the outside of the front end of the cylindrical explosion-proof joint 4, and an annular flange 6 is provided on the inside. The annular flange and the explosion-proof joint are integrally cast, and the annular flange 6 is used to set the sealing lock up. The annular groove 5 is processed by lathe cutting. The explosion-proof joint 4 is provided with screw holes or internal threads.
[0035] Step 3: insert the front end of the explosion-proof joint 4 obtained in step 2 into the installation hole 7 of the side plate 3, and the front end is flush with the inner wall of the ...

The invention discloses an anti-explosion junction box welding technology. According to the technical scheme, the anti-explosion junction box welding technology is characterized by comprising the following steps that (1) a base plate, a flange and a set of side plates are firstly assembled through a tool clamp, and fixing is carried out through spot welding; (2) an annular groove is formed in theouter side of the front end of an anti-explosion connector, and an annular flange is arranged on the inner side of the front end of the anti-explosion connector; (3) the front end of the anti-explosion connector obtained in the step (2) is inserted into installing holes of the side plates, and fixing is carried out through spot welding; (4) an anti-explosion junction box obtained from the step (1)to the step (3) is fixed to a welding table; and (5) a welding robot is used for welding a connecting gap of the anti-explosion junction box, and at least the position of the connecting gap of the anti-explosion connector and the inner side of the side plate is welded.
Description
technical field [0001] The invention relates to a welding process for an explosion-proof junction box. Background technique [0002] Explosion-proof junction box is a special power distribution equipment used in various high-risk places. Compared with civilian junction boxes, it is a power distribution box with explosion-proof function after various explosion-proof transformations. Several explosion-proof joints are welded on the box body of the explosion-proof junction box. The structure and welding method of traditional explosion-proof joints are as follows: the overall structure is a central cylinder, the rear end is provided with screw holes or internal threads for connecting with the connectors on the cable, and the front end is flush and set on the side plate of the explosion-proof junction box On the wire inlet hole, the diameter of the wire inlet hole is smaller than the inner hole of the explosion-proof joint, and then manually weld the connection gap between the e...
