[0002] In production and life, the role of electromechanical equipment is indispensable, and a large number of electromechanical equipment are used in the production and manufacturing of buildings. The most important equipment in the electromechanical equipment used in buildings is the distribution box. The distribution box has the functions of reasonably distributing electric energy, facilitating the opening and closing operations of the circuit, and intuitively displaying the conduction status of the circuit. When the distribution box is produced, a bending machine is usually used to bend the metal plate into the frame of the distribution box, and the joints in the bent frame are welded; then the frame is placed on the metal back cover, and the frame is positioned, and the four joints between the bottom edge of the frame and the metal back cover are welded, and automatic welding equipment is used for welding, but the existing automatic welding equipment can generally only move in one direction during welding, and the welding efficiency is low. Summary of the Invention

[0003] In order to overcome the above-mentioned technical problems, the purpose of the present invention is to provide an automatic welding equipment for building electromechanical equipment, which moves the connecting rod, the fixing ring and the welding gun to appropriate positions by starting the electric push rod, and moves the welding gun along the direction of the connecting shell one by starting the motor three, and then moves the welding gun along the direction of the connecting shell two by starting the motor four. The moving mechanism is used to quickly change the position of the welding gun, so that the automatic welding equipment for building electromechanical equipment can weld building distribution boxes of different specifications and sizes, and can perform horizontal and vertical welding on building distribution boxes, thereby improving the welding efficiency of the automatic welding equipment for building electromechanical equipment.

[0004] The purpose of the present invention can be achieved through the following technical solutions:

[0005] An automatic welding device for building mechanical and electrical equipment includes a base. A rectangular shell is fixedly connected to the top of the base. A U-shaped plate is fixedly connected to the top of the rectangular shell. Two connection gaps are symmetrically opened on the top of the rectangular shell with respect to its center line. A welding machine is fixedly connected to the top of one side of the U-shaped plate. A connecting wire harness is installed and fixed at the output end of the welding machine, and one end of the connecting wire harness is fixedly connected to a welding torch. A clamping mechanism for fixing a distribution box is provided on the rectangular shell in a matching manner. A moving mechanism for adjusting the position of the welding torch is provided on the inner top surface of the U-shaped plate. When in use, it is convenient to weld a building distribution box by using the welding machine, the connecting wire harness and the welding torch. The clamping mechanism is used to centrally fix building distribution boxes of different specifications and sizes. And the moving mechanism is used to quickly change the position of the welding torch, so that the automatic welding device for building mechanical and electrical equipment can weld building distribution boxes of different specifications and sizes, and can weld the building distribution box horizontally and vertically, improving the welding efficiency of the automatic welding device for building mechanical and electrical equipment.

[0006] Furthermore, the clamping mechanism includes a rectangular tube. Rectangular rods are slidably connected to both ends inside the rectangular tube.

A first gear is sleeved and fixed at the middle position of the outer side wall of the rectangular tube. A first motor is provided at the bottom of the rectangular tube. The output end of the first motor is fixedly connected to a second gear, and the second gear meshes with the first gear. An adjustment unit is provided outside the first motor. By starting the first motor, the first motor drives the second gear to rotate, and the second gear meshes with the first gear, so that the first gear, the rectangular tube, the rectangular rod and the first screw rod rotate. The first screw rod is screwed with the threaded hole, so that the two L-shaped rods move towards each other, and then the two bearing shells move towards each other, and further the two corners of the building distribution box are squeezed and fixed by moving the two bearing shells.

[0007] Furthermore, a first rubber pad is fixedly connected to the middle position of the top of the rectangular shell. A second rubber pad is fixedly connected inside the bearing shell.

[0011] Furthermore, the moving mechanism includes a second fixed shell. The top of the second fixed shell is in contact with the inner top surface of the U-shaped plate. A second connecting shell is fixedly connected to the middle position at one end of the second fixed shell.

One end of the connecting rod is fixedly connected to a fixing ring, and the inner side wall of the fixing ring is fixedly connected to the outer side wall of one end of the welding torch. By starting the electric push rod, the connecting rod and the fixing ring move, and then the welding torch moves to an appropriate position. By starting the fourth motor, the third screw rod rotates, so that the second moving block, the connecting rod, and the fixing ring move, and then it is convenient for the welding torch to move along the direction of the second connecting shell.

[0012] Furthermore, the moving mechanism further includes a first fixed housing, and one end of the first fixed housing is fixedly connected to one side of the U-shaped plate. At the middle position of the other end of the first fixed housing, a first connecting housing is fixedly connected in a communicating manner.
