As welding proceeds, the weld smoothing scraper can first scrape the welding liquid so that the welding liquid can be evenly distributed on the weld. After cooling, the weld can be smoothed simultaneously without subsequent processing. Through this design, the telescopic welding gun can change its position in real time as the welding area changes, and no special laser scanning adjustment structure is required, which greatly improves the stability of the equipment during welding and effectively reduces the equipment cost.

After cooling, the weld can be smoothed synchronously without the need for subsequent processing.

[0043] Through this design, the telescopic welding gun 10 can change its position in real time as the welding area changes, and no special laser scanning adjustment structure is required to assist, which greatly improves the stability of the equipment during welding and effectively reduces the equipment cost. At the same time, during the welding process, the weld can be smoothed synchronously, which greatly improves the aesthetics of the weld, improves the product welding effect, and improves the equipment application effect.

The two telescopic heat radiation covers 44 are symmetrically arranged about the longitudinal center plane of the mounting plate 43. An adjustment motor 42 is fixedly installed on the outer wall of one side of the mounting plate 43.

[0045] A sheet metal positioning component 41 is fixedly installed at one end of the output shaft of the adjusting motor 42, and the sheet metal positioning component 41 is used for, the sheet metal positioning component 41 includes a side panel 413, a bottom clamping plate 414 is fixedly installed at the bottom end of the side panel 413, a slide groove 412 is arranged on one side outer wall of the side panel 413, a mounting slider 411 is slidably installed inside the slide groove 412, a positioning spring 415 is fixedly installed on the top surface of the mounting slider 411, and the top end of the positioning spring 415 is fixedly connected to the top surface of the slide groove 412, a movable clamping plate 416 is fixedly installed at one end of the mounting slider 411, and a pull ring is fixedly installed on the side wall of the movable clamping plate 416.

[0046] The specific implementation method is as follows: when welding sheet metal parts, pull up the movable clamping plate 416, and place one end of the two sheet metal parts between the movable clamping plate 416 and the bottom clamping plate 414 respectively. At this time, release the movable clamping plate 416, and the movable clamping plate 416 can stably position the sheet metal parts through the positioning spring 415, turn on the adjustment motor 5, and the adjustment motor 5 can drive the double-threaded rod 8 to rotate, and the double-threaded rod 8 can control the two sheet metal mounting mechanisms 4 to approach each other until the welding surfaces of the two sheet metal parts are in contact with each other.

During the welding process, the adjustment motor 42 can be controlled to start, and the adjustment motor 42 can drive the sheet metal positioning component 41 to rotate slowly. The sheet metal positioning component 41 drives the sheet metal to rotate slowly, thereby gradually changing the welding area of ​​the sheet metal parts, until the sheet metal parts rotate one circle, and a round of welding of the sheet metal parts is completed. In this way, multiple welding can be performed.

[0047] Through this design, when welding sheet metal parts, not only can the sheet metal parts be quickly positioned, but the welding position and area of ​​the sheet metal parts can also be quickly changed by rotary welding, thereby achieving all-round and multiple welding of the sheet metal parts, greatly improving the welding effect and firmness, and improving the application effect of the equipment.

During the welding process, the adjustment motor 42 can be controlled to start. The adjusting motor 42 can drive the sheet metal positioning component 41 to rotate slowly, and the sheet metal positioning component 41 drives the sheet metal to rotate slowly, thereby gradually changing the welding area of ​​the sheet metal until the sheet metal rotates one circle and completes a round of welding of the sheet metal. In this way, multiple welding can be performed. After the welding areas of the two sheet metals are docked, if the sides of the two sheet metals are not completely aligned, the alignment push plate 9 can be controlled to push sideways to align the sheet metals completely. At this time, the area of ​​the telescopic heat radiation cover 44 is controlled so that the telescopic heat radiation cover 44 completely covers the sheet metal. At this time, welding is performed. During the welding process, the walking wheel 119 will directly contact the sheet metal. As the sheet metal As the sheet metal rotates, the travel wheel 119 will continue to roll. As the position of the welding area of ​​the sheet metal changes, the surface condition also changes accordingly. Since the surface travel component 11 is provided with a connecting spring 111, the connecting spring 111 can keep the travel wheel 119 in contact with the surface of the sheet metal. Therefore, the position of the travel wheel 119 will also change with the change of the surface of the sheet metal, and synchronously drive the telescopic welding gun 10 to adjust its position according to the surface condition of the sheet metal, so that the telescopic welding gun 10 is always located in the most suitable position for welding the sheet metal. At the same time, since the weld flattening scraper 117 is located exactly in the middle of the surface travel component 11 Therefore, the weld smoothing scraper 117 can be in continuous contact with the weld of the sheet metal part. As welding proceeds, the weld smoothing scraper 117 can also continue to scrape the weld. As welding proceeds, the weld smoothing scraper 117 can first scrape the welding liquid so that the welding liquid can be evenly distributed on the weld. After cooling, the weld can be smoothed simultaneously without subsequent processing.
