In the process of electromechanical installation, it is often necessary to weld a welding piece on the surface of a thick welding piece or a forming device. For such a thick welding piece, clamping is not possible. CONTENT OF THE INVENTION

[0027] As Figures 1-7 shown, a welding device for mechanical and electrical installation provided by the embodiment of the present application is described. The welding device for mechanical and electrical installation comprises a top plate 101, a bottom plate 100 and a connecting column 102 connecting the top plate 101 and the bottom plate 100, the top plate 101 and the bottom plate 100 are arranged in parallel, the first clamping plate 103 is slidingly installed on the connecting column 102, the first spring 104 is sleeved on the connecting column 102 between the first clamping plate 103 and the top plate 101, the two ends of the first spring 104 are fixedly connected with the first clamping plate 103 and the top plate 101 respectively, the first spring 104 drives the first clamping plate 103 to keep a downward movement trend, the second clamping plate 105 is arranged below the first clamping plate 103 on the bottom plate 100, the front side of the first clamping plate 103 is provided with a clamping groove 106, and two clamping heads 107 are elastically arranged in the clamping groove 106. The two clamping heads 107 are used to clamp a welding piece, and the welding piece is clamped on another welding piece through cooperation of the first clamping plate 103 and the second clamping plate 105, so as to ensure stability of the welding piece during welding; for the convenience of understanding, the welding piece clamped by the two clamping heads 107 is a first welding piece, and the second clamping plate 105 is connected with a second welding piece, and it can be understood that the thickness or size of the first welding piece is smaller than that of the second welding piece.

[0028] Preferably, the second clamping plate 105 is rotationally connected with the bottom plate 100, and the upper surface of the second clamping plate 105 is provided with a suction cup 201, which can make the second clamping plate 105 fixedly connected with the second welding piece; as Figure 6 shown, when the thickness of the second welding piece is thin, the second clamping plate 105 is in a horizontal state, the second welding piece is fixedly placed on the suction cup 201, and the first welding piece clamped by the two clamping heads 107 is fixedly arranged on the upper surface of the second welding piece under the abutting action of the first spring 104, so as to facilitate welding of the first welding piece and the second welding piece. As Figure 7As shown, when the thickness of the second welding piece is thick or the second welding piece is in a shaped arrangement, the second clamping plate 105 is first rotated to a vertical state, and the suction cup 201 is adsorbed on the side surface of the second welding piece to fix the welding device on the side surface of the second welding piece, and then the first welding piece is clamped by the other clamping head 107 and fixed on the upper surface of the second welding piece under the pressing action of the first spring 104 to perform welding. Through the setting of the suction cup 201 and the rotational setting of the second clamping plate 105, the welding device has a more flexible clamping mode to be suitable for welding pieces of different shapes and thicknesses. In the embodiment, generally, the welding piece contains iron or can be attracted to a magnet, so the suction cup 201 is preferably a magnetic suction cup, such as a magnet; of course, the suction cup 201 can also be a negative pressure suction cup, that is, connected to a negative pressure suction system, and adsorbed by pressure; or a magnetic suction cup with a plurality of adsorption holes connected to a negative pressure suction system in a detachable manner.

[0029] In order to ensure the stability of the fixed angle between the second clamping plate 105 and the bottom plate 100 and not affect the rotational relationship therebetween, as shown in Figure 4 and Figure 5 A plurality of equidistance positioning grooves 202 are arranged on both sides of the bottom plate 100, the positioning grooves 202 are arranged in a rotational center circular arc array, the second clamping plate 105 is provided with a placing groove 203 corresponding to the position of the positioning groove 202, a positioning bead 204 is installed in each placing groove 203, a positioning spring 205 is fixed in the placing groove 203, one end of the positioning spring 205 is connected with the positioning bead 204, and the other end is connected with the bottom of the placing groove 203; the diameter of the positioning bead 204 is greater than the diameter of the positioning groove 202, and the diameter of the positioning bead 204 is less than the diameter of the placing groove 203. The positioning spring 205 acts to press part of the positioning bead 204 into the positioning groove 202, thereby limiting the relative rotation of the bottom plate 100 and the second clamping plate 105, when a larger rotating force is applied to the second clamping plate 105, the positioning spring 205 will be compressed due to the arc surface of the positioning bead 204, the positioning bead 204 returns to the placing groove 203, so that the second clamping plate 105 can rotate relative to the bottom plate 100.

[0030] In the embodiment, as shown in Figure 3As shown, the first clamping plate 103 is a T-shaped plate, and the clamping head 107 is arranged at the wide end face of the T-shaped plate, so as to increase the moving stroke of the two clamping heads 107, increase the thickness of the clamped first welding piece, and improve the versatility. Specifically, a limiting rod 301 is fixed in the clamping groove 106, the clamping groove 106 is a rectangular groove with an open end face, and the two clamping heads 107 are slidingly installed on the limiting rod 301 and cannot rotate; a second spring 108 is arranged between each clamping head 107 and the end face of the clamping groove 106, the two second springs 108 are sleeved on the limiting rod 301 and drive the two clamping heads 107 to approach each other, and the two clamping heads 107 clamp the first welding piece under the elastic force of the two second springs 108.

[0031] In order to facilitate holding and moving the welding device, the welding device is provided with a handle 303. Figure 1 As shown, the top plate 101 and the bottom plate 100 are fixed with a connecting plate 302, and the outer side face of the connecting plate 302 is provided with a holding handle 303; the welding device is more convenient to operate through the holding handle 303, and the user's use experience and convenience are improved.

[0032] The use process of the welding device is as follows: the two clamping heads 107 are separated, and the second spring 108 is compressed; the first welding piece is placed between the two clamping heads 107, the separation force of the two clamping heads 107 is removed, the second spring 108 is released, and the two clamping heads 107 clamp the first welding piece under the action of the second spring 108; the first clamping plate 103 is moved upward, the first spring 104 is compressed, the second welding piece is placed on the second clamping plate 105 and is sucked by the suction cup 201, the first clamping plate 103 is loosened, the first clamping plate 103 moves downward under the action of the first spring 104, and the first welding piece is vertically attached to the upper surface of the second welding piece; when the thickness of the second welding piece is too thick or the second welding piece is a forming device, the second clamping plate 105 is rotated to a vertical state, the second clamping plate 105 is then fixed to the side face of the second welding piece by using the suction cup 201, and then the first welding piece is vertically attached to the upper surface of the second welding piece.
