Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, the utility model provides a mobile laser welding device, including a base shell 1, a motor shell 2 is fixedly installed on one end of the upper surface of the base shell 1, a fixture 3 is rotatably installed on the motor shell 2, a motor driving the fixture 3 is installed inside the motor shell 2, a first bracket 7 is fixedly installed on one end of the upper surface of the base shell 1 away from the motor shell 2, a third electric telescopic rod 71 is fixedly installed on the top of the first bracket 7, a conical head 72 is fixedly installed on the telescopic end of the third electric telescopic rod 71, and one end of the base shell 1 is fixedly installed on the upper surface of the base shell 1. A support block 11 is fixedly installed on the side, a bending and shaping rod 4 is fixedly installed on the support block 11, and a laser welding gun 41 is fixedly installed on the top of the bending and shaping rod 4. In actual use, the cylindrical workpiece to be welded is clamped in the middle of the fixture 3, and then the third electric telescopic rod 71 is driven to work. At this time, the third electric telescopic rod 71 pushes the conical head 72 to fix the workpiece, and the bending and shaping rod 4 can be bent. The laser welding gun 41 is aligned with the position to be welded, and then the motor drives the fixture 3 to rotate, and then the surface of the cylinder is welded.

[0022] A slide groove 12 is provided on the upper surface of the base shell 1, and a rust removal and grinding device 5 is provided inside the slide groove 12. The rust removal and grinding device 5 is located below the side of the fixture 3 away from the motor housing 2, and the laser welding gun 41 is located above the fixture 3. A polishing device 6 is installed on the upper surface of the base shell 1, and the polishing device 6 is located on the side of the rust removal and grinding device 5 away from the bending and shaping rod 4. The rust removal and grinding device 5 includes two first electric telescopic rods 51, and a support seat 52 is provided for sliding inside the slide groove 12. The telescopic end of the first electric telescopic rod 51 is fixedly installed on the support seat 52. A plurality of evenly distributed card grooves 53 are provided on the upper surface of the support seat 52, and a spring telescopic rod 54 is fixedly installed inside the card groove 53. The telescopic ends of the plurality of spring telescopic rods 54 are fixedly installed with a connecting plate 55, and a semicircular sandpaper board 56 is detachably installed on the upper surface of the connecting plate 55. A rust removal knife 57 is fixedly installed on one side of the upper surface of the support seat 52, and the rust removal knife 57 is located on the side of the support seat 52 close to the polishing device 6.

[0023] When in use, the clamp 3 will drive the workpiece to rotate counterclockwise. At this time, the rotation speed of the clamp 3 is relatively slow during welding. After welding, the clamp 3 will increase the rotation speed. Often, only one circle is required to complete welding. However, to meet actual production requirements, multiple welding can be performed to increase the firmness of the weld. Rust will cause rust on the surface of the material, which will have an adverse effect on the physical and chemical properties of the welding material, such as tensile strength, plasticity, toughness, etc., affecting the welding quality. During welding, welders often need to clean the weld. If the surface of the welding material is rusty, it is difficult to clean and cracks are easily generated during the welding process. , holes and other defects affect the welding quality, so by setting the rust removal and grinding device 5, the first electric telescopic rod 51 is driven to work before welding, and the first electric telescopic rod 51 lifts the support seat 52 until the rust removal knife 57 touches the surface of the workpiece. At this time, the semicircular sandpaper board 56 will be compressed by the spring telescopic rod 54 due to the extrusion of the workpiece, and then the clamp 3 is driven to rotate rapidly. At this time, the larger block debris and coarse rust on the surface of the workpiece will be scraped off by the rust removal knife 57, and the semicircular sandpaper board 56 will grind the rust on the surface of the workpiece during the rotation process, thereby making the surface of the workpiece clean during welding and preventing rust on the surface from affecting the quality of welding.

[0024] The polishing device 6 includes two third brackets 61, and the top of the two third brackets 61 is fixedly installed with a fourth bracket 62, the middle position of the two fourth brackets 62 is rotatably installed with a fan 64, and the middle position of the top of the two third brackets 61 is fixedly installed with a second electric telescopic rod 63, and the telescopic end of the second electric telescopic rod 63 is detachably installed with a polishing sponge 65.

[0025] The processing of some workpieces has high requirements on the smoothness and flatness of the surface, so the welding slag and the protruding parts of the welding on the surface of the workpiece need to be ground and polished. Traditionally, when processing such workpieces, workers mostly perform manual grinding after the welding process is completed. In the case of large production volume, it will lead to slow processing progress and require a lot of labor costs. There is a lack of fast and integrated response methods. Therefore, a rust removal and grinding device 5 and a polishing device 6 are set. During the welding process, the rust removal and grinding device 5 and the polishing device 6 are both in working state. At this time, the semicircular sandpaper 56 is against the lower surface of the workpiece, and the polishing sponge 65 is against the side surface of the workpiece. The laser welding gun 41 welds the workpiece above it. The weld formed by welding will be transported to one side of the polishing device 6 as the fixture 3 rotates. At this time, the fan 64 works to cool the weld, and then the cooled weld will be clamped The tool 3 is transported to the top of the rust removal and grinding device 5, at which time the raised part of the weld will be scraped off by the rust removal knife 57, and the small protrusions on the workpiece surface will be polished flat by the semicircular sandpaper board 56. Because multiple spring telescopic rods 54 are provided, the protrusion of the weld will push the semicircular sandpaper board 56 to compress the spring telescopic rod 54. The compressed spring telescopic rod 54 will generate a relatively large thrust, and the thrust of the uncompressed spring telescopic rod 54 is relatively small. Therefore, multiple semicircular sandpaper boards 56 can be polished with different intensities according to the degree of protrusion on the workpiece surface, and the rust removal and grinding device 5 can be adapted to workpieces of different diameters. Under the continuous rotation of the fixture 3, the polished weld will be cyclically transported to one side of the polishing device 6, and at this time, the polishing sponge 65 will polish the surface of the workpiece without disassembling the workpiece. The grinding and polishing process can be carried out simultaneously with the welding process, thereby reducing dependence on manual labor and increasing production speed.

[0026] It should be noted that workers can replace the polishing sponges 65 and the semicircular sandpaper boards 56 with different meshes according to the surface smoothness actually required for processing, or choose to add polishing agents with different meshes to increase the polishing effect.

[0027] A leakage groove 13 is provided on the upper surface of the base shell 1, and the leakage groove 13 is located on the side of the rust removal knife 57 away from the spring telescopic rod 54. The leakage groove 13 is connected to the interior of the base shell 1, and the internal sliding card of the base shell 1 is provided with a drawer plate 8. By setting the drawer plate 8, the welding slag scraped by the rust removal knife 57 will fall into the interior of the base shell 1 through the leakage groove 13 and fall on the top of the drawer plate 8, so that the welding slag will be collected. During continuous processing, the welding slag will not accumulate, the cleanliness of the work surface can be kept, and the continuous processing capacity of the device can be improved.

[0028] A plurality of evenly distributed second brackets 9 are fixedly mounted on the lower surface of the base housing 1, and a universal wheel 91 is mounted on the bottom end of the second bracket 9. The universal wheel 91 has the functions of moving and locking, thereby enabling the device to be moved or fixed.
