Description

Technical Field

[0001] The present invention relates to the technical field of electric welding equipment, and particularly to an electric welding equipment with an auxiliary positioning electric welding gun. Background Art

[0002] Welding equipment is a special equipment used to realize the connection of metal materials. It combines two or more metal parts together by heating or applying pressure (or both). There are various types of welding equipment, covering a variety of application scenarios such as manual welding, automatic welding, and special welding;

[0003] During the welding process, in order to prevent the welding area from being polluted by harmful gases in the air (such as oxygen and nitrogen) and improve the welding quality and stability, it is usually necessary to spray a shielding gas on the welding area. However, when the electric welding gun welds metal materials, it will generate sparks and splashes, and these splashes will adhere to the nozzle of the shielding gas, affecting the spraying flow rate of the shielding gas. Since it is difficult for the operator to immediately detect the change in the spraying flow rate of the shielding gas, when the shielding gas flow rate is insufficient, the air in the welding area cannot be completely excluded, and oxygen and nitrogen in the air will enter the molten pool. Oxygen will react with the metal in the molten pool to form oxide inclusions, affecting the purity and performance of the weld, resulting in pores in the welded joint, thereby reducing the strength and corrosion resistance of the weld. Moreover, if the shielding gas flow rate is too small, it cannot effectively protect the welding droplets, increasing the splashes during the welding process, resulting in a rough surface of the weld and affecting the appearance and quality of the weld.

[0004] Therefore, the present invention proposes an electric welding equipment with an auxiliary positioning electric welding gun to solve the above problems. Summary of the Invention

[0017] (III) Beneficial effects

[0018] Compared with the prior art, the present invention provides a welding device with an auxiliary positioning electric welding gun, having the following beneficial effects:

[0019] 1. Through the provided gas flow monitoring mechanism, when the flow rate of the shielding gas ejected from the gas spray pipe becomes small, the display lamp can be automatically turned off. This not only facilitates the staff to timely discover and solve the problem of insufficient shielding gas flow rate, enabling them to quickly take measures to clean the nozzle of the gas spray pipe or adjust the gas flow rate, thereby effectively avoiding welding defects such as pores and oxide inclusions caused by insufficient gas flow rate, improving the strength and corrosion resistance of the weld seam, but also preventing the occurrence of spatter during the welding process due to the influence of too small shielding gas flow rate, reducing the surface roughness of the weld seam, improving the appearance and quality of the weld seam, and thus reducing the material waste and rework costs caused by welding defects.

[0020] 2. When the flow rate of the shielding gas becomes small, the counterweight block pushes the pressing plate away from the button to turn off the display lamp. Not only is the force provided by the counterweight constant after its weight is determined and will not change due to time, temperature, or usage frequency. In contrast, a spring will experience problems such as fatigue, deformation, or weakened elasticity during long-term use, resulting in unstable force provided by it. Moreover, the counterweight block has a simple structure without complex mechanical components, so it hardly requires maintenance during use, while the spring needs to be regularly inspected and replaced. Especially in high-frequency use or harsh environments, fatigue and damage of the spring are common problems.

[0021] 3. By setting up the welding path positioning and cleaning mechanism, it is possible to observe whether the roller fits the welding position, which can help the operator align the welding gun with the welding position. The intuitive visual feedback can not only significantly improve the positioning accuracy of the welding gun, reduce welding defects caused by position deviation, facilitate the operator to adjust the position of the welding gun more quickly, and reduce the time wasted in searching for the welding starting point, thus significantly improving the welding efficiency. Moreover, for novice or inexperienced operators, the roller fitting technology provides a more intuitive and simpler positioning method, reducing the difficulty of welding operation, making the welding process easier to master, and reducing the dependence on the operator's skill level.

[0022] 4. By setting up the connecting shaft, friction disk, cam, rotating shaft, convex groove, sliding column, connecting frame, and fixed column, during the process of the roller rolling along the welding path, it can drive the moving block to slide synchronously and reciprocally on the outer surface of the mounting column, and drive the cleaning brush connected to the lower end of the fixed column to reciprocally clean the welding path. This not only cleans the impurities and spatter on the welding path in real time, ensures that the welding area always remains clean, thereby improving the welding quality, but also effectively removes the impurities and oxides in the welding area through automatic cleaning of the welding path, further reducing the formation of welding defects such as pores and inclusions, and thus improving the strength and corrosion resistance of the weld seam.

[0023] Among them, by setting up the slider, chute, linkage frame, threaded rod, and knob, it is possible to drive the friction disk to move on the outer surface of the connecting shaft, adjust the position of the friction disk from the center of the cam on the lower end face of the cam, thereby changing the transmission ratio between the friction disk and the cam, and adjusting the reciprocating cleaning speed of the cleaning brush on the welding path according to requirements. This not only improves the welding quality and operation convenience, but also enhances the adaptability and performance of the cleaning brush, and improves the safety and efficiency of the overall welding process.

[0036] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0037] A welding device with an auxiliary positioning electric welding gun in this embodiment, as Figure 1 - Figure 7As shown in the figure, it includes a welding table 1. A gantry 2 is fixedly connected to the upper end surface of the welding table 1. A moving frame 3 is slidably connected to the gantry 2. A welding gun 4 and a mounting frame 5 are fixedly connected to the moving frame 3. A gas spray pipe 6 is fixedly connected to the welding gun 4. Vertical grooves 9 are formed on both sides of the mounting frame 5. It also includes a gas flow monitoring mechanism and a welding path positioning and cleaning mechanism. The gas flow mechanism includes a display lamp 705. The display lamp 705 is fixedly connected to the upper end surface of the mounting frame 5. Connecting columns 703 are symmetrically and slidably penetrated through the mounting frame 5. A moving plate 701 is fixedly connected between one ends of the two connecting columns 703 close to the gas spray pipe 6. A pressing plate 702 is fixedly connected to the upper end surface of the moving plate 701. A button 707 is fixedly connected to one side of the mounting frame 5 close to the pressing plate 702. The button 707 and the pressing plate 702 are on the same horizontal line. The button 707 is electrically connected to the display lamp 705. The gas flow monitoring mechanism is used to detect the flow rate of the protective gas sprayed by the gas spray pipe 6.

[0038] In this embodiment, as Figure 2 and Figure 3 shown in the figure, lifting plates 704 are rotatably connected to both sides of the moving plate 701. Lifting blocks 708 are rotatably connected to one ends of the lifting plates 704 away from the moving plate 701. The lifting blocks 708 are slidably connected in the vertical grooves 9. When the moving plate 701 moves towards the mounting frame 5, the arranged lifting plates 704 can push the lifting blocks 708 to slide upwards synchronously in the vertical grooves 9.

[0039] In this embodiment, as Figure 3 shown in the figure, a lifting column 709 is fixedly connected to the upper end of the lifting block 708. The lifting column 709 is slidably penetrated through the mounting frame 5. A counterweight block 706 is fixedly connected to the upper end of the lifting column 709. When the lifting block 708 is forced to rise, the arranged lifting column 709 can push the counterweight block 706 to move upwards synchronously. When the force on the lifting block 708 disappears, due to the influence of the self - gravity of the counterweight block 706, the counterweight block 706 can push the lifting block 708 to automatically descend through the lifting column 709.

[0040] In the prior art, since it is difficult for the staff to detect the change in the jet flow rate of the shielding gas in a timely manner, when the shielding gas flow rate is insufficient, the air in the welding area cannot be completely excluded. Oxygen and nitrogen in the air will enter the molten pool. Oxygen will react with the metal in the molten pool to form oxide inclusions, affecting the purity and performance of the weld, resulting in the formation of pores at the welded joint, thereby reducing the strength and corrosion resistance of the weld. Moreover, when the shielding gas flow rate is too small, the welding molten droplet cannot be effectively protected, increasing the spatter during the welding process, resulting in a rough weld surface, affecting the appearance and quality of the weld. Compared with the prior art, when the flow rate of the shielding gas ejected from the gas injection pipe 6 becomes small, the display lamp 705 can be automatically turned off, which not only facilitates the staff to timely detect and solve the problem of insufficient shielding gas flow rate, enabling them to quickly take measures to clean the nozzle of the gas injection pipe 6 or adjust the gas flow rate, thereby effectively avoiding welding defects such as pores and oxidation inclusions caused by insufficient gas flow rate, improving the strength and corrosion resistance of the weld, and also avoiding the increase in spatter during the welding process affected by too small shielding gas flow rate, reducing the roughness of the weld surface, improving the appearance and quality of the weld, thereby reducing material waste and rework costs caused by welding defects.

[0041] At other levels, this embodiment also provides a welding path positioning and cleaning mechanism for assisting the welding gun 4 to move to a specified position at the welding site, as Figure 2 , Figure 4 - Figure 7 shown. The welding path positioning and cleaning mechanism includes a support column 816. The support column 816 is fixedly connected to the lower end surface of the mounting frame 5. A connecting block 810 is fixedly connected to the lower end of the support column 816. A roller 811 is arranged below the connecting block 810. A connecting shaft 812 is fixedly connected through the roller 811. The connecting shaft 812 is rotatably connected through the connecting block 810. The roller 811 and the welding gun 4 are on the same path.

[0042] In this embodiment, as Figure 5 shown, the welding path positioning and cleaning mechanism further includes a mounting column 801. The mounting column 801 is fixedly connected to the side wall of the mounting frame 5 away from the moving plate 701. A moving block 809 is slidably connected to the outer surface of the mounting column 801. A fixing column 808 is fixedly connected to the lower end of the moving block 809. A cleaning brush 807 is fixedly connected to the lower end of the fixing column 808. When driving the moving block 809 to slide on the outer surface of the mounting column 801, the cleaning brush 807 can be driven to move synchronously through the fixing column 808 connected to the lower end of the moving block 809, so that the cleaning brush 807 cleans the welding path.

[0043] In this embodiment, as Figure 6As shown, sliding grooves 817 are formed on the outer surfaces of the connecting shafts 812. Sliders 818 are slidably connected in the sliding grooves 817. Friction discs 813 are fixedly connected to the sliders 818. Cam discs 803 are attached to the upper sides of the friction discs 813. Rotating shafts 802 are fixedly connected to the centers of the upper end faces of the cam discs 803. The rotating shafts 802 are rotatably connected to the lower end face of the mounting bracket 5. When the connecting shafts 812 rotate, the sliders 818 are driven by the sliding grooves 817 formed on the outer surfaces to drive the friction discs 813 to rotate synchronously. As the friction discs 813 rotate, affected by the frictional force between the outer surfaces of the friction discs 813 and the lower end faces of the cam discs 803, the friction discs 813 will drive the cam discs 803 to drive the rotating shafts 802 to rotate on the lower end face of the mounting bracket 5. At the same time, since the sliders 818 are slidably connected to the sliding grooves 817, the friction discs 813 can be driven to slide horizontally on the outer surfaces of the connecting shafts 812 to adjust the distance between the centers of the friction discs 813 and the cam discs 803.

[0044] In this embodiment, as Figure 4 and Figure 6 shown, convex grooves 804 are formed on the upper end faces of the cam discs 803. Slide posts 805 are slidably connected in the convex grooves 804. A connecting frame 806 is fixedly connected between the upper ends of the two slide posts 805. The connecting frame 806 is fixedly connected to the fixed column 808. When the cam discs 803 rotate, the positions of the convex grooves 804 can be changed, causing the slide posts 805 to slide in the convex grooves 804. At the same time, affected by the shape of the convex grooves 804, when the slide posts 805 slide along the paths of the convex grooves 804, the fixed column 808 can be pushed to move horizontally back and forth synchronously through the connecting frame 806.

[0045] In this embodiment, as Figure 7 shown, linkage frames 814 are fixedly connected to the sides of the friction discs 813 away from the connecting blocks 810. Rotating threaded rods 819 are rotatably connected through the centers of the linkage frames 814. The rotating threaded rods 819 are threadedly connected to the connecting shafts 812. Knobs 815 are fixedly connected to the ends of the rotating threaded rods 819 away from the connecting shafts 812. When the knobs 815 are rotated to drive the rotating threaded rods 819 to rotate and the connecting shafts 812 are controlled not to rotate, due to the threaded connection between the rotating threaded rods 819 and the connecting shafts 812, the rotating threaded rods 819 can be rotated and slid out from the inside of the connecting shafts 812. During the rotational movement of the rotating threaded rods 819, the friction discs 813 can be pulled to move horizontally synchronously through the linkage frames 814 rotatably connected to their outer surfaces.

[0046] Compared with the prior art, being able to observe whether the roller 811 is attached to the welding point can help the staff to align the welding gun 4 with the welding point. The intuitive visual feedback can not only significantly improve the positioning accuracy of the welding gun 4, reduce welding defects caused by position deviation, facilitate the staff to adjust the position of the welding gun 4 more quickly, and reduce the time wasted in searching for the welding starting point, thus significantly improving the welding efficiency. Moreover, for novice or inexperienced staff, the roller 811 attachment technology provides a more intuitive and simpler positioning method, reduces the difficulty of welding operation, makes the welding process easier to start, and reduces the dependence on the skill level of the operator.

[0047] The working process and principle involved in the overall content of the above embodiments are as follows:

[0048] When the staff needs to weld metal materials, first place the material to be welded on the welding table 1, then move the welding point under the roller 811, and observe whether the roller 811 is attached to the welding point. After the roller 811 and the welding point are perfectly attached, the staff can then clamp and fix the welding material through the existing clamping mechanism, which can help the staff to align the welding gun 4 with the welding point. The intuitive visual feedback can not only significantly improve the positioning accuracy of the welding gun 4, reduce welding defects caused by position deviation, facilitate the staff to adjust the position of the welding gun 4 more quickly, and reduce the time wasted in searching for the welding starting point, thus significantly improving the welding efficiency. Moreover, for novice or inexperienced staff, the roller 811 attachment technology provides a more intuitive and simpler positioning method, reduces the difficulty of welding operation, makes the welding process easier to start, and reduces the dependence on the skill level of the operator;

[0049] After the welding torch 4 and the welding path position are adjusted, the operator can turn on the welding torch 4 to weld the welding area. At the same time, the protective gas is ejected through the gas spray pipe 6 and blown to the welding area of the welding torch 4. As the protective gas is ejected, the protective gas will come into contact with the moving plate 701 at the same time, pushing the moving plate 701 in the direction of the mounting bracket 5, driving the connecting column 703 to slide horizontally on the mounting bracket 5, and at the same time pulling the pressing plate 702 connected to the upper end face of the moving plate 701 closer to the button 707 connected to the side wall of the mounting bracket 5. When the pressing plate 702 comes into contact with the button 707, the button 707 is electrically connected to the display lamp 705, and the display lamp 705 can be turned on for operation. During the process of the moving plate 701 approaching the mounting bracket 5, the moving plate 701 will push the lower ends of the two rotatably connected lifting plates 704 to move horizontally synchronously, causing the lifting plates 704 to move from an inclined state to an almost vertical state. As the state of the lifting plates 704 changes, the lifting plates 704 will push the lifting block 708 connected to the end away from the moving plate 701 to slide vertically upward in the vertical groove 9, driving the lifting column 709 connected to the upper end face of the lifting block 708 to rise out of the mounting bracket 5, and at the same time lifting the counterweight block 706 connected to the upper end of the lifting column 709. When the outlet of the gas spray pipe 6 is blocked, resulting in a decrease in the flow rate of the protective gas, the thrust received by the moving plate 701 will also decrease. At this time, affected by the self-gravity of the counterweight block 706, the counterweight block 706 will push the lifting column 709 to descend, driving the lifting block 708 to move downward synchronously in the vertical groove 9. As the lifting block 708 descends, the lifting block 708 will push the moving plate 701 away from the mounting bracket 5 through the lifting plate 704, and drive the pressing plate 702 connected to the upper end face of the moving plate 701 to separate from the button 707. After the pressing plate 702 and the button 707 are completely separated, the display lamp 705 connected to the upper end of the mounting bracket 5 will automatically turn off. This not only facilitates the operator to promptly discover and solve the problem of insufficient protective gas flow rate, enabling them to quickly take measures to clean the nozzle of the gas spray pipe 6 or adjust the gas flow rate, thereby effectively avoiding welding defects such as pores and oxide inclusions caused by insufficient gas flow rate, improving the strength and corrosion resistance of the weld, but also avoiding the occurrence of an increase in spatter during the welding process due to too small a protective gas flow rate, reducing the surface roughness of the weld, improving the appearance and quality of the weld, and thus reducing the material waste and rework costs caused by welding defects;

[0050] When driving the moving frame 3 to move horizontally on the gantry 2 and driving the welding gun 4 to weld along the welding path, the rollers 811 will roll synchronously while fitting the surface of the welding path, driving the connecting shaft 812 connected to the rollers 811 to rotate synchronously on the connecting block 810. As the connecting shaft 812 rotates, since the friction disc 813 is connected to the outer surface of the connecting shaft 812, the friction disc 813 fits against the lower end surface of the cam 803, and the cam 803 is rotatably connected to the lower end surface of the mounting frame 5 through the rotating shaft 802. Therefore, during the rotation of the connecting shaft 812, the connecting shaft 812 will drive the friction disc 813 to rotate synchronously, and through the frictional force between the friction disc 813 and the lower end surface of the cam 803, drive the cam 803 to drive the rotating shaft 802 to rotate synchronously on the lower end surface of the mounting frame 5. Since the upper end surface of the cam 803 is provided with a convex groove 804, a sliding column 805 is slidably connected in the convex groove 804, a connecting frame 806 is connected between the sliding columns 805, and the connecting frame 806 is fixedly connected to the fixed column 808. Therefore, as the cam 803 rotates, the sliding column 805 can be made to slide synchronously in the convex groove 804. At the same time, affected by the convex groove 804, the sliding column 805 will push the connecting frame 806 to drive the fixed column 808 to move, so that the moving block 809 connected to the upper end of the fixed column 808 reciprocally slides on the outer surface of the mounting column 801, and drives the cleaning brush 807 connected to the lower end of the fixed column 808 to reciprocally clean the welding path. This not only cleans the impurities and spatter on the welding path in real time, ensures that the welding area is always kept clean, thereby improving the welding quality, but also can effectively remove the impurities and oxides in the welding area through automatic cleaning of the welding path, further reducing the formation of welding defects such as pores and inclusions, thereby improving the strength and corrosion resistance of the weld;

[0051] When the staff believes that the reciprocating speed of the cleaning brush 807 is slow, resulting in an unsatisfactory cleaning effect on the welding path, the two-side knobs 815 can be rotated to drive the threaded rod 819 to rotate. During the rotation of the threaded rod 819, the staff needs to control the connecting shaft 812 to prevent the connecting shaft 812 from rotating synchronously with the threaded rod 819. As the threaded rod 819 rotates, through the threaded connection between the threaded rod 819 and the connecting shaft 812, the threaded rod 819 can be driven to rotate and slide out from inside the connecting shaft 812. Since the linkage frame 814 is rotatably connected to the outer surface of the threaded rod 819, the linkage frame 814 is fixedly connected to the friction disk 813, and the friction disk 813 is slidably connected to the outer surface of the connecting shaft 812 through the slider 818 and the chute 817. Therefore, during the process of the threaded rod 819 rotating and sliding out from inside the connecting shaft 812, the friction disk 813 can be pulled to slide synchronously on the outer surface of the connecting shaft 812 through the linkage frame 814, adjusting the position of the friction disk 813 from the center of the cam 803 on the lower end surface of the cam 803, thereby changing the transmission ratio between the friction disk 813 and the cam 803, and adjusting the reciprocating cleaning speed of the cleaning brush 807 for the welding path according to the requirements. This not only improves the welding quality and operation convenience, but also enhances the adaptability and performance of the cleaning brush 807, and improves the safety and efficiency of the overall welding process.
