Specific embodiments
[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.
[0022] Embodiment: Refer to Figures 1-4An auxiliary positioning mechanism for a handheld laser welding machine shown in the figure includes a rectangular frame 1 and four L-shaped blocks 2. The rectangular frame 1 and the four L-shaped blocks 2 are connected by a lifting component. Slide grooves are provided on the sides of the four L-shaped blocks 2, and fixing components are arranged in the four slide grooves. A transmission groove is provided on the inner wall of the peripheral side of the rectangular frame 1. Two arc-shaped sliders 7 are slidably installed in the transmission groove through a sliding component. A rotating ring 12 is rotatably installed on the inner wall of the peripheral sides of the two arc-shaped sliders 7. A limiting component adapted to the rotating ring 12 is provided on one of the arc-shaped sliders 7. A fixing block 14 is fixedly installed on the inner wall of the peripheral side of the rotating ring 12. Two mounting shafts 15 are jointly arranged on the side of the fixing block 14 and the inner wall of the peripheral side of the rotating ring 12. A welding head fixing seat 16 is slidably installed on the two mounting shafts 15. An adjusting component is arranged on the side of the welding head fixing seat 16. An operating column 20 is fixedly installed on the top of the fixing block 14.
[0023] With the above structure, during use, first, the rectangular frame 1 is fixedly installed on the welding table through multiple fixing components, and the laser welding head is arranged on the welding head fixing seat 16. Then, the rectangular frame 1 and the laser welding head are driven by the lifting component to be adjusted to an appropriate height. Then, when linear welding is required, the two arc-shaped sliders 7 and the rotating ring 12 are driven to move horizontally through the sliding component, so as to realize the horizontal welding function. When welding a circular track is required, the rotating ring 12 is driven by the sliding component to move to an appropriate position. Then, the welding head fixing seat 16 is driven to slide on the two mounting shafts 15 through the adjusting component, and the welding head fixing seat 16 is adjusted to an appropriate position according to the diameter of the circular track. Then, the limit of the rotating ring 12 by the limiting component is released, and the rotating ring 12 is driven to rotate through the operating column 20, so as to realize the welding function of the circular track, improving the stability during welding.
[0024] As Figure 3 shown in the figure, the lifting component includes four hydraulic cylinders 3. The four hydraulic cylinders 3 are respectively fixedly installed on the tops of the four L-shaped blocks 2. The output ends of the four hydraulic cylinders 3 are fixedly connected to the bottom of the rectangular frame 1. The advantage of such a setting is that through the setting of the four hydraulic cylinders 3, the lifting function of the rectangular frame 1 can be driven, facilitating the adjustment of the height of the laser welding head.
[0025] Specifically, when the height of the laser welding head needs to be adjusted, start the multiple hydraulic cylinders 3, and then drive the rectangular frame 1 to realize the lifting function, so as to facilitate the adjustment of the height of the rectangular frame 1 and the laser welding head, so as to adapt to workpieces to be welded with different thicknesses.
[0026] As Figure 3As shown, the fixing component includes a pressing plate 4. The inner wall of the top of the chute is rotatably installed with a threaded rod 5. The bottom end of the threaded rod 5 extends outside the L-shaped block 2 and is fixedly provided with a knob 6. The pressing plate 4 is threadedly installed on the threaded rod 5. The advantage of this setting is that through the setting of the pressing plate 4 and the threaded rod 5, the pressing plate 4 can be driven to move up and down, so as to fix welding tables with different thicknesses.
[0027] Specifically, when it is necessary to fix the return frame 1, the inner walls of the tops of multiple L-shaped blocks 2 are all placed in contact with the top of the welding table, and then multiple knobs 6 are rotated. When the knobs 6 are rotated, the threaded rods 5 are driven to rotate synchronously, so as to drive the pressing plate 4 to move upward, thereby realizing the clamping and fixing of the welding table.
[0028] As Figure 3 shown, the sliding component includes two lead screws 8. The two ends of the two lead screws 8 are respectively rotatably installed on the opposite inner walls of the transmission groove. The two lead screws 8 are connected by a transmission unit. Two arc-shaped sliders 7 are respectively threadedly installed on the two lead screws 8. The advantage of this setting is that through the setting of the two lead screws 8, the horizontal movement function of driving the two arc-shaped sliders 7 can be realized.
[0029] Specifically, when it is necessary to perform linear welding or adjust the welding position, rotate the two lead screws 8 to drive the arc-shaped sliders 7 to move horizontally synchronously, so as to drive the rotating ring 12 and the welding head fixing seat 16 to move synchronously, thereby realizing the linear welding function or the function of adjusting the welding position.
[0030] As Figure 3 shown, the transmission unit includes two sprockets 9. The two sprockets 9 are respectively fixedly sleeved on the two lead screws 8. A chain 10 is commonly meshed and installed on the two sprockets 9. A driving motor 11 is fixedly installed on the side of the return frame 1. The output shaft of the driving motor 11 is connected to the end of one of the lead screws 8. The advantage of this setting is that through the setting of the two sprockets 9 and the chain 10, the synchronous rotation of the two lead screws 8 can be realized, and the phenomenon of jamming during horizontal movement can be prevented.
[0031] Specifically, when the driving motor 11 is started, one of the lead screws 8 and the sprocket 9 are driven to rotate, and then under the meshing action of the sprocket 9 and the chain 10, the other sprocket 9 and the lead screw 8 are driven to rotate synchronously, and then the two arc-shaped sliders 7 are driven to move horizontally synchronously, preventing the phenomenon of jamming during the movement process.
[0032] As Figure 4 shown, the limiting component includes a limiting bolt 13. A threaded hole is opened on the inner wall of the top of the arc-shaped slider 7. The limiting bolt 13 is threadedly installed in the threaded hole. The advantage of this setting is that through the setting of the limiting bolt 13, the fixing function of the rotating ring 12 can be realized through the limiting bolt 13, preventing it from rotating randomly.
[0033] Specifically, when it is necessary to fix the rotating ring 12, rotate the limit bolt 13 to press the rotating ring 12, thereby realizing the limit of the rotating ring 12 and preventing it from rotating. When it is necessary to rotate the rotating ring 12, the limit of the limit bolt 13 on the rotating ring 12 can be released, and then the rotating function can be realized, which is convenient for the welding operation of the circular track.
[0034] Such as Figure 4 As shown, the adjusting assembly includes a screw guide sleeve 17. A circular groove is formed in the side of the fixed block 14. The screw guide sleeve 17 is rotatably installed in the circular groove. The inner wall of the end of the circular groove is provided with a motor groove, and an adjusting motor 18 is fixedly installed in the motor groove. The output shaft of the adjusting motor 18 is connected to the end of the screw guide sleeve 17. A screw 19 is installed in the screw guide sleeve 17 by internal threads. The end of the screw 19 is fixedly connected to the side of the welding head fixing seat 16. The advantage of this setting is that the rotation of the screw guide sleeve 17 drives the screw 19 to move horizontally, and then the position of the welding table fixing seat 16 is adjusted, which is convenient for the welding operation of circular tracks with different diameters.
[0035] Specifically, when it is necessary to weld circular tracks with different diameters, start the adjusting motor 18 to drive the screw guide sleeve 17 to rotate, and then drive the screw 19 and the welding head fixing seat 16 to move horizontally synchronously under the limiting action of the two mounting shafts 15, so as to realize the welding of circular tracks with different diameters.
[0036] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
