[0024] like Figure 1-4As shown, a welding device for automobile nut plates includes a bottom plate 1, two fixed plates 5 are arranged at the top of the bottom plate 1, a controller 6 is arranged on one side of one of the fixed plates 5, a conveying member 7 is conveyed between the two fixed plates 5, the conveying member 7 includes two pulleys 702 rotatably arranged between the two fixed plates 5, a conveying belt 703 is transmitted and conveyed between the two pulleys 702, a second motor 701 is arranged on one side of one of the fixed plates 5, one of the pulleys 702 is connected to the main shaft end of the second motor 701, and the conveying belt 703 is connected to the main shaft end of the second motor 701. A plurality of limiting posts 10 are arranged on the surface of the belt 703, and an automobile sheet metal 9 is placed on the conveying belt 703. The limiting posts 10 correspond to the nut mounting holes on the automobile sheet metal 9. A mounting frame 2 is arranged on the top of the bottom plate 1, and a welding device 3 is movably arranged below the mounting frame 2. Specifically, two groups of limiting posts 10 are arranged on the surface of the conveying belt 703, so that after the automobile sheet metal 9 is placed on the conveying belt 703, the limiting posts 10 can be inserted into the threaded groove position on the automobile sheet metal 9, and then the nuts 8 can be respectively sleeved on the limiting posts 1. 0, and then the conveying member 7 can drive the automobile sheet metal 9 to be conveyed forward. After the nut 8 is conveyed to the bottom of the welding device 3, the driving member 4 can drive the welding device 3 to move, and the welding head on the welding device 3 corresponds to the position of the nut 8. Therefore, in the subsequent welding process, there is no need to manually move the position of the automobile sheet metal 9, and all the nuts 8 are sleeved in a suitable position. In the subsequent welding, it is not necessary to place the nuts 8 on the limiting columns 10 one by one, so as to avoid scalding the staff when placing the nuts 8, and it is safer to use. The two groups of limiting columns 10 are respectively arranged on the upper and lower sides of the conveying belt 703, so after the welding of the upper automobile sheet metal 9 is completed, the limiting columns 10 of the lower group can be rotated to the upper position. Since for the same batch of automobile sheet metals 9, the welding position is the same when the nut groove is welded, the driving member 4 and the conveying member 7 can be debugged during use, so that it can automatically adjust the position of the welding device 3. It is a prior art, so it is not described in detail here.

[0025] like Figure 2 As shown, a driving component 4 for driving the welding equipment 3 to move is provided on the installation frame 2, and the driving component 4 includes a slide rail 401 arranged at the bottom end of the installation frame 2, a first motor 403 is provided on one side of the slide rail 401, a screw rod 404 is connected to the main shaft end of the first motor 403, a slider 402 is provided for sliding inside the slide rail 401, and the slider 402 is threadedly sleeved on the screw rod 404; specifically, the first motor 403 can drive the screw rod 404 to rotate when it works, and the rotation of the screw rod 404 can drive the slider 402 to slide on the slide rail 401, thereby driving the welding equipment 3 to translate.

[0026] like Figure 2As shown, an electric telescopic rod 405 is provided at the bottom end of the slider 402, and the welding equipment 3 is connected to the telescopic end of the electric telescopic rod 405; specifically, the extension and retraction of the electric telescopic rod 405 can drive the welding equipment 3 to move up and down.

[0027] like Figure 2 As shown, a nut 8 is movably sleeved on the limiting column 10; specifically, the nut 8 is sleeved on the limiting column 10, thereby being able to play a preliminary limiting role on the nut 8, making it convenient to accurately weld it to the nut groove position on the automobile sheet metal 9.

[0028] like Figure 2 and 4 As shown, a plurality of evenly arranged supporting rollers 12 are rotatably disposed between the two fixed plates 5 .

[0029] like Figure 2 and 4 As shown, the support roller 12 fits the top and bottom surfaces of the conveyor belt 703, and two groups of limit plates 11 are arranged on the conveyor belt 703; specifically, the support roller 12 can support the automobile sheet metal 9 to prevent its heavy weight from affecting the transportation, and the two groups of limit plates 11 are of different colors, so the two groups of limit columns 10 can be distinguished. After the welding of the automobile sheet metal 9 is completed, it is removed from the conveyor belt 703. The length of the conveyor belt 703 is long enough, so after the welding of the automobile sheet metal 9 is completed, it can still support it, which is convenient for removing it later.

[0030] In summary: two groups of limiting columns 10 are arranged on the surface of the conveyor belt 703, so after the automobile sheet metal 9 is placed on the conveyor belt 703, the limiting columns 10 can be inserted into the threaded groove position on the automobile sheet metal 9, and then the nuts 8 can be respectively sleeved on the limiting columns 10, and then the conveying component 7 can drive the automobile sheet metal 9 to be transported forward, and when the nuts 8 are transported to the bottom of the welding equipment 3, the driving component 4 can drive the welding equipment 3 to move, and the welding head on the welding equipment 3 is aligned with the position of the nuts 8, so that in the subsequent welding process, there is no need to manually move the position of the automobile sheet metal 9, and all the nuts 8 are sleeved in appropriate positions. In subsequent welding, there is no need to place the nuts 8 on the limiting columns 10 one by one, thereby avoiding scalding of the staff when placing the nuts 8, and it is safer to use.

[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model.
