Then the electrical box is placed in the fixed tooling welding platform, and the related connectors and accessories are adjusted to meet the product requirements. Finally, manual welding is performed. Its disadvantages are: 1. Poor versatility. When welding and assembling electrical boxes of different models, it is necessary to constantly switch the corresponding connectors (support seats and positioning parts, etc.), which leads to low production efficiency and waste of manpower; 2. Mechanical positioning is adopted, which cannot be flexibly positioned and cannot adapt to changes in the electrical box; 3. It is complicated to replace the positioning parts after they are worn out. Most positioning parts are non-standard parts, and the subsequent maintenance costs are high. 4.

[0014] Example 1 like Figures 1 to 4 As shown, a universal electrical box assembly and welding tool is used to limit and fix the electrical box that needs to be assembled and welded, so as to facilitate assembly and welding. The tool is provided with a symmetrically arranged base 1, and two movable mechanisms that can be relatively movable are installed on the two bases 1; the movable mechanisms each include a base slide rail 2, the base slide rail 2 is slidably installed and connected to the base 1, and the top of the base slide rail 2 is respectively fixedly connected with a support column 21, and the tops of the two support columns 21 are connected by adjusting the gantry beam 4; the two sides of the adjusting gantry beam 4 are respectively slidably installed with a positioning cylinder 5, and the positioning cylinder 5 is installed with a limiting mechanism for pressing and limiting the electrical box; the two positioning cylinders 5 are arranged between two matching cylinders 6, and the two matching cylinders 6 are slidably connected to the adjusting gantry beam 4, and the two matching cylinders 6 are respectively connected with a movable corner mechanism for limiting the side wall of the electrical box. By assembling the various parts of the electrical box that need to be assembled and welded according to the design, and placing them between the adjustable gantry beams 4 of the two movable mechanisms of the tooling; and each support column 21 is respectively connected with a limit baffle 22 for limiting the electrical box; in this way, the assembled electrical box can be limited in the entire tooling. Then the positioning cylinder 5 is controlled to drive the respective connected limit mechanisms to limit the assembled electrical box; and the matching cylinder 6 is controlled to drive the movable corner mechanism to limit the position of the side wall of the assembled electrical box; thereby, the entire assembled electrical box is limited in the entire tooling, so as to facilitate welding.

[0015] Example 2 Based on Example 1, the two bases 1 (equivalent to the sliding guide rails) of the tooling are used to be installed and fixed at the specified position, and the electrical box that has been assembled and needs to be welded is placed between the two. At the same time, two movable mechanisms that can be relatively movable are respectively installed on the two symmetrically arranged bases 1 anchored to the ground. The movable mechanisms all include base slide rails 2, which are slidably installed and connected to the base 1, and the tops of the base slide rails 2 are respectively fixedly connected to the support columns 21, and the tops of the two support columns 21 are connected by adjusting the gantry beam 4; the two sides of the adjusting gantry beam 4 are respectively slidably installed and connected with positioning cylinders 5, and the positioning cylinders 5 are installed and connected with a limiting mechanism for pressing and limiting the electrical box; the two positioning cylinders 5 are arranged between the two matching cylinders 6, and the two matching cylinders 6 are slidably connected to the adjusting gantry beam 4, and the two matching cylinders 6 are respectively connected with a movable corner mechanism for limiting the side wall of the electrical box. In order to prevent the frame of the assembled electrical box from moving and dislocating during welding, the positioning cylinder 5 can be controlled to drive the limiting mechanism to limit the top position of the assembled electrical box; and the matching cylinder 6 can be controlled to drive the movable corner mechanism to limit the side wall position of the assembled electrical box; and then the tooling designed can be used to limit and fix the entire assembled electrical box to prevent movement and dislocation during welding, thereby ensuring the welding quality of the entire electrical box.

[0016] Example 3 The limit mechanism of the arrangement includes a positioning limit block 51; one end of the positioning limit block 51 is connected to the rod body of the output end of the positioning cylinder 5, and a rotating shaft is respectively rotatably penetrated on the positioning limit block 51, and the rotating shaft is connected to the limit movable arm 52 through a hinge seat, and the limit movable arm 52 is connected to a first pressing plate 53 for pressing and limiting the electrical box. The rotating shaft penetrated on the positioning limit block 51 is driven to rotate by a driving motor arranged in the cavity of the positioning limit block 51. The positioning cylinder 5 is slidably arranged with the adjusting gantry crossbeam 4 through a sliding rail; the first pressing plate 53 is installed and connected with an inner support cylinder assembly 7 for limiting the electrical box.

[0017] In addition, the movable corner mechanism includes a corner limit block 61; one end of the corner limit block 61 is connected to the rod body of the output end of the matching cylinder 6, and a rotating shaft is respectively rotatably penetrated on the corner limit block 61, and the rotating shaft is connected to a corner movable arm 62 through a hinge seat, and the corner movable arm 62 is connected to a second side pressure plate 63 for pressing and limiting the side wall of the electrical box.

[0018] In the embodiment, by controlling the extension and contraction of the positioning cylinder 5, the positioning limit block 51 connected to the positioning cylinder 5 is driven to move to a suitable position, and then by controlling the rotating shaft penetrating the positioning limit block 51, the limit movable arm 52 is driven to rotate to a suitable angle position, and the first pressing plate 53 connected to the limit movable arm 52 is driven to limit the top surface of the assembled electrical box. At the same time, fixed cylinders 3 are respectively connected to the two sides of one end surface of the two adjusting gantry beams 4 that are close to each other, and the fixed cylinders 3 are controlled to limit the top surface of the electrical box. In order to better limit the position of the entire assembled electrical box, the assembled electrical box can also be further limited by controlling the inner support cylinder assembly 7.

[0019] At the same time, in order to ensure that the side of the assembled electrical box is also limited, the fixed matching cylinder 6 can be controlled to extend and retract, thereby driving the corner limit block 61 connected to the matching cylinder 6 to move to a suitable position, and then the rotating shaft penetrating the corner limit block 61 is controlled to drive the corner movable arm 62 to rotate to a suitable angle position, and drive the second side pressure plate 63 connected to the corner movable arm 62 to limit the side wall end face of the assembled electrical box.

Finally, through the above-mentioned control and adjustment, the entire assembled electrical box is clamped and limited on the "X, Y, Z" axis, and no shaking occurs during welding; and it can adapt to the size of the electrical box that needs to be welded, making the tooling more widely applicable. The tooling has the advantages of firm clamping, precise and reliable positioning, convenient operation, and a large size adjustment range. It is suitable for special and general quick replacement, high production efficiency when matched with welding robots, and low cost investment.
