[0002] In the prior art, the electrical box shell on the clean water tank and the sewage tank is usually welded with the shell plate during the processing. Since the shell plate is thin, it is easy to deform after welding and difficult to reshape. In order to ensure that the electrical box shell does not deform after welding, an anti-deformation welding tool and process are required. Summary of the invention

[0003] In view of the shortcomings of the above-mentioned existing production technology, the applicant provides an anti-deformation welding tool and processing technology for the housing of an electrical box, so as to achieve convenience and speed in use, easy reshaping in the later stage, and improve work efficiency.

[0004] The technical solution adopted by the present invention is as follows:

[0005] A welding tool for preventing deformation of an electrical box shell comprises a bottom plate, wherein the front and rear ends of the bottom plate are respectively bent upward to form a front side plate and a rear side plate, and the left and right ends of the bottom plate are respectively welded to a left side plate and a right side plate, and the bottom plate, the left side plate, the right side plate, the front side plate and the rear side plate constitute a rectangular structure with an open opening, with the open opening facing upward; a fixed plate is fitted and clamped in the middle position of the top surfaces of the left side plate, the right side plate, the front side plate and the rear side plate, and the fixed plate forms a "U"-shaped structure, a "cross"-shaped structure is arranged on the upper part of the rectangular structure, and connecting components are installed on the outer end surfaces of the "cross"-shaped structure, and the heads of the connecting components are abutted against the corresponding fixing plates.

[0006] Its further technical solution is:

[0007] The "cross"-shaped structure is formed by the first support rod and the second support rod being staggered and connected at 90 degrees.

[0008] The first support rod and the second support rod have the same structure. The second support rod has a structure comprising a long strip structure with a rectangular groove in the middle and circular pits in the middle of both end surfaces of the long strip structure.

[0009] The length of the second support rod is greater than that of the first support rod.

[0010] The structure of the connecting assembly is as follows: it includes a screw rod, one end of which is fixed with a gasket through a first nut, the outer surface of the gasket is a smooth surface, the other end of the screw rod is sleeved with a second nut, and the gasket is against a fixing plate.

[0011] The upper parts of the left side panel, the right side panel, the front side panel and the rear side panel are all provided with flanges.

[0012] One end of the right side panel forms a No. 1 weld with the rear side panel, the other end of the right side panel forms a No. 2 weld with the front side panel, one end of the left side panel forms a No. 3 weld with the rear side panel, the other end of the left side panel forms a No. 4 weld with the front side panel, the bottom of the left side panel forms a No. 5 weld with the left end of the bottom plate, and the bottom of the right side panel forms a No. 6 weld with the right end of the bottom plate.

[0013] A processing technology for anti-deformation welding of an electrical box housing includes the following steps:

[0014] Step 1: Prepare the bottom plate, front side plate and rear side plate, which are bent into a "U" shape;

[0015] Step 2: Prepare the left side panel and the right side panel;

[0016] Step 3: Grind all the materials prepared in Steps 1 and 2 to remove the oil and rust 25mm on both sides of the weld;

[0017] Step 4: Place the fixing plates on the middle of the top surfaces of the front side plates and the rear side plates respectively, place the first support rod between the front side plates and the rear side plates, and install the connecting components on both ends of the first support rod respectively, so that the gaskets of the connecting components respectively support the fixing plates of the front side plates and the rear side plates;

[0018] Step 5: The second support rod is connected to the first support rod at the middle position to form a "cross" structure. At this time, the two ends of the second support rod are also installed with connecting components, so that the gaskets of the connecting components respectively support the fixing plates of the left side panel and the right side panel;

[0019] Step 6: Weld the No. 1 weld, the No. 4 weld, the No. 2 weld and the No. 3 weld in sequence;

[0020] Step 7: Weld the No. 5 weld and the No. 6 weld;

[0021] Step 8: Welding is completed;

[0022] Step 9: Remove the support rods, connecting components and fixing plates;

[0023] Step 10: Processing completed.

[0024] As a further improvement of the above technical solution:

[0025] In the seventh step, when welding the No. 5 weld and the No. 6 weld, weld from the middle to both sides.

[0026] The beneficial effects of the present invention are as follows:

[0027] The invention has a compact and reasonable structure and is easy to operate. Through the two support rods, the connecting assembly and the fixing plate, the housing of the electrical box can be conveniently fixed to prevent the housing of the electrical box from shrinking and deforming after welding, thereby reducing the scrap rate of the workpiece, saving the later shaping time and improving the work efficiency.

[0028] The screw rod of the present invention can be used in combination with the circular pit, or can be used separately, thereby achieving good flexibility, high working efficiency and reduced costs.

[0029] The invention can adjust the length of the screw rod by the depth of the circular pit opened on the support rod, and is suitable for electrical box shells on clean water tanks and sewage tanks of various specifications. BRIEF DESCRIPTION OF THE DRAWINGS
