DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0037] like Figures 1-8 As shown, a parts welding device for sports equipment production provided by an embodiment of the present invention includes a workbench 1, the upper end surface of the workbench 1 is fixedly connected to an electric lifting frame 4, and positioning devices 2 are provided on both sides of the electric lifting frame 4, which are driven to extend and retract by hydraulic pressure, and the electric lifting frame 4 is slidably connected to a connecting frame 11, and the electric lifting frame 4 is connected to a driving mechanism 3 that can drive the connecting frame 11 to move horizontally, and the driving mechanism 3 is composed of a No. 3 motor and a threaded transmission rod, the No. 3 motor drives the threaded transmission rod to rotate, and the threaded transmission rod pushes the connecting frame 11 to move horizontally through threaded transmission, the connecting frame 11 is connected to a sleeve 12, the sleeve 12 is connected to a conical connecting sleeve 14, an electrode 16 is provided in the middle of the connecting sleeve 14, the sleeve 12 is connected to a wire tube 13, an electric wire and an air pipe pass through the wire tube 13, the electric wire is connected to the electrode 16, one end of the air pipe is connected to the inside of the connecting sleeve 14 through the wire tube 13, and the other end of the air pipe is connected to a protective gas storage tank;

[0038] The connecting sleeve 14 is connected to a connecting pipe 17, which can guide the welding rod. The connecting pipe 17 is provided with a thrust mechanism 18 for conveying the welding rod. The thrust mechanism 18 is composed of a conveying wheel driven by a No. 4 motor. The motor drives the conveying wheel to rotate, and the conveying wheel pushes the welding rod forward through friction. The connecting pipe 17 is connected to a pretreatment device 7, which can heat and grind the welding rod; the electrode 16 is provided with a diverter mechanism 6, which can adjust the airflow direction of the protective gas. The connecting sleeve 14 is connected to a drainage device 5, which can drain the high-temperature gas and welding slag in the connecting sleeve 14 to the outside;

[0039] The control system can control the drainage device 5, the diversion mechanism 6 and the pretreatment device 7 according to the temperature conditions, humidity conditions and the forming state of the molten pool near the welding position, thereby improving the welding quality.

[0040] In this embodiment, two sports equipment parts to be welded are placed on a workbench 1 and aligned, and two positioning devices 2 are activated to fix the two sports equipment parts respectively;

[0041] Then, the electric lifting frame 4 is started to lower the height so that the filter sleeve 15 is close to the surfaces of the two sports equipment parts. Then, the electrode 16 is energized and an arc is generated. At this time, the thrust mechanism 18 pushes the welding rod in the connecting pipe 17 forward, thereby welding the two sports equipment parts.

[0042] Before welding, the welding rod is preheated and polished by the pretreatment device 7 to reduce the temperature gradient in the welding area; during welding, the positioning device 2 cooperates with the cooling water to position the sports equipment parts. At this time, the cooling water can suppress the thermal deformation of the sports equipment parts, reduce the degree of freedom displacement of the sports equipment parts during the welding process, and improve the positioning accuracy of the sports equipment parts;

[0043] During welding, the control system can control the drainage device 5, the diversion mechanism 6, the pretreatment device 7 and the thrust mechanism 18 according to the temperature and humidity conditions near the welding position and the forming state of the molten pool;

[0044] When the welding temperature is too high, the control system controls the drainage device 5 to accelerate the discharge of hot air from the welding position to achieve a cooling effect on the welding position;

[0045] When the humidity in the external environment is high, in order to avoid excessive moisture on the weldment and electrode surface around the welding area, which may lead to an increase in the incidence of hydrogen-induced porosity, the control system increases the delivery speed of the protective gas and adjusts the diversion mechanism 6 to adjust the flow direction of the protective gas so that the protective gas is concentrated towards the welding area and the electrode delivery direction;

[0046] When the airflow velocity of the protective gas is too high, the welding liquid on the surface of the molten pool fluctuates and affects the forming quality of the welding part. At this time, the diversion mechanism 6 can adjust the airflow direction of the protective gas to reduce the direct rush of the protective gas to the welding part, and at the same time start the drainage device 5 to accelerate the transportation of the protective gas in the connecting sleeve 14 to the surface of the sports equipment parts outside the connecting sleeve 14.

[0047] like Figure 6 As shown in FIG. 5 , as a preferred embodiment of the present invention, the drainage device 5 includes a protective sleeve 51 , a guide hole 52 , a convex plate 53 and a drainage plate 54 ;

[0048] The protective sleeve 51 is rotatably connected to the lower end of the connecting sleeve 14. A plurality of guide holes 52 are provided on the side wall of the protective sleeve 51. A convex plate 53 is provided in an annular manner at the lower end of the protective sleeve 51. A plurality of guide plates 54 are rotatably connected to the convex plate 53 through an elastic torsion spring. A power mechanism No. 1 55 capable of driving the protective sleeve 51 to rotate is provided on the connecting sleeve 14. The power mechanism No. 1 55 consists of a No. 1 motor and a No. 1 gear. The No. 1 motor drives the No. 1 gear to rotate. The No. 1 gear drives the protective sleeve 51 to rotate by meshing with the gear ring on the outer wall of the protective sleeve 51. The outside of the protective sleeve 51 is fixedly connected to the filter sleeve 15.

[0049] In this embodiment, when the connecting sleeve 14 drives the drainage device 5 close to the sports equipment parts, the drainage device 5 can protect the welding part to prevent the temperature loss of the welding part and the splashing of welding slag;

[0050] When the protective gas blows straight downward, the convex plate 53 can intercept some of the protective gas. At this time, the first power mechanism 55 is activated to drive the protective sleeve 51 to rotate. The protective sleeve 51 drives all the guide plates 54 inside it to rotate. Under the guidance of the guide plates 54, the protective gas is discharged to the outside of the protective sleeve 51 through the convex plate 53.

[0051] The drainage device 5 can discharge the hot air or protective gas in the connecting sleeve 14 to the outside. On the one hand, it can regulate the welding temperature of the welding part and maintain the welding temperature stable; further, in this process, under the guiding action of the drainage device 5, the hot air can dry the moisture on the surface of the sports equipment parts near the welding part, thereby reducing the incidence of hydrogen-induced porosity; on the other hand, when the molten pool state is unstable, the drainage device 5 and the diversion mechanism 6 can cooperate to change the flow direction of the protective gas, thereby maintaining the stability of the molten pool state.

[0052] like Figure 6As shown, as a preferred embodiment of the present invention, the diversion mechanism 6 includes a No. 2 electric telescopic sleeve 61 and a baffle 62. The No. 2 electric telescopic sleeve 61 is fixedly connected to the outer wall of the electrode 16 through an insulating sleeve. The output end of the No. 2 electric telescopic sleeve 61 is fixedly connected to a conical baffle 62. The baffle 62 is made of insulating material. The power cord of the No. 2 electric telescopic sleeve 61 passes through the wire tube 13 to connect to the external power supply.

[0053] In this embodiment, the second electric telescopic sleeve 61 can drive the baffle 62 to change height through telescopic movement. When the baffle 62 is close to the top of the connecting sleeve 14, the baffle 62 is close to the protective gas inlet, and the baffle 62 has an enhanced diversion effect on the protective gas. At this time, the protective gas is dispersed to both sides of the welding area, reducing the disturbance of the protective gas to the weld pool.

[0054] When the external humidity is high, the delivery rate of the protective gas into the connecting sleeve 14 is increased. At the same time, the control system controls the No. 2 electric telescopic sleeve 61 to adjust the height of the baffle 62 to be located at the lower side of the connecting pipe 17. At this time, under the guidance of the baffle 62, the protective gas is diverted to the connecting pipe 17, thereby reducing the air humidity near the welding rod, and at this time, the drainage device 5 is started to accelerate the diversion of the gas in the connecting sleeve 14 to the vicinity of the connecting sleeve 14, so that the air humidity around the welding part is reduced.

[0055] like Figure 5 As shown, as a preferred embodiment of the present invention, the pre-treatment device 7 includes a rotating drum 71, a second power mechanism 72 and a grinding mechanism 73;

[0056] The rotating drum 71 is rotatably connected to the connecting pipe 17 . The connecting pipe 17 is provided with a second power mechanism 72 capable of driving the rotating drum 71 to rotate. The rotating drum 71 is provided with a grinding mechanism 73 , which can contact heat and grind the welding rod.

[0057] In this embodiment, when the welding rod passes through the rotating drum 71, the conveying wheel in the thrust mechanism 18 squeezes and limits the welding rod, and the grinding mechanism 73 in the rotating drum 71 contacts the welding rod, starting the No. 2 power mechanism 72, and the No. 2 power mechanism 72 drives the rotating drum 71 to rotate, and the rotating drum 71 drives the grinding mechanism 73 to rotate around the welding rod, so that the grinding mechanism 73 grinds the surface of the welding rod to remove oxides and other impurities on the surface, ensuring the cleanliness and smoothness of the welding surface, thereby improving the welding quality.

[0058] like Figure 7As shown, as a preferred embodiment of the present invention, the grinding mechanism 73 includes an electric telescopic rod 731, a splint 732 and an electric heater 733. Two electric telescopic rods 731 are relatively arranged on the rotating drum 71. The telescopic ends of the electric telescopic rods 731 are fixedly connected with splints 732. The splints 732 are arc-shaped plates. Electric heaters 733 are provided on the splints 732. The power cord of the electric heater 733 passes through the rotating drum 71 and is connected to an external power supply.

[0059] In this embodiment, the electric telescopic rod 731 is started, and the electric telescopic rod 731 drives the clamping plate 732 to contact the surface of the welding rod. At this time, the electric heater 733 can be energized to heat the clamping plate 732, and the clamping plate 732 transfers heat to the welding rod, thereby preheating the welding rod. At the same time, during the transportation of the welding rod, the clamping plate 732 can grind the surface of the welding rod to generate heat, which can avoid the appearance of hydrogen-induced pores in the welding part due to excessive humidity on the surface of the welding rod during welding. At the same time, during the transportation of the welding rod, the protective gas is transported to the rotating drum 71 through the connecting pipe 17. On the one hand, it can take away the dust polished out of the surface of the welding rod, and on the other hand, it can keep the dryness of the air near the welding rod, thereby improving the welding quality.

[0060] like Figure 8 As shown, as a preferred embodiment of the present invention, a plurality of No. 1 guide grooves 8 are obliquely arranged on the inner wall of the electric heater 733, a No. 2 guide groove 9 is arranged in the middle of the inner wall of the electric heater 733, and the No. 2 guide groove 9 is connected to all the No. 1 guide grooves 8. The other end of the rotating drum 71 away from the connecting pipe 17 is also connected to the filter drum 10, and a filter screen is spirally arranged in the filter drum 10, and a dust cloth is laid on the filter screen.

[0061] In this embodiment, when the splint 732 grinds the surface of the welding rod, the slag and dust produced by the splint 732 falls into the No. 1 guide groove 8 and the No. 2 guide groove 9. At this time, the air flow enters the rotating drum 71 from the connecting pipe 17, and the air flow can be dispersed into each No. 1 guide groove 8 through the No. 2 guide groove 9, thereby taking away the slag and dust in all the No. 1 guide grooves 8 and the No. 2 guide grooves 9, avoiding a large amount of impurities sticking to the surface of the welding rod.

[0062] like Figure 2 As shown, as a preferred embodiment of the present invention, the positioning device 2 includes a fixing frame 21, a No. 1 electric telescopic sleeve 22 and a water-cooled lower pressure plate 23;

[0063] Both sides of the electric lifting frame 4 are fixedly connected with a fixing frame 21, and the fixing frame 21 is fixedly connected with a retractable electric telescopic sleeve No. 1. The telescopic end of the electric telescopic sleeve No. 1 is fixedly connected with a water-cooled lower pressure plate 23. The electric telescopic sleeve No. 1 is connected with a water pipe joint. A cold water pipe is arranged around the inside of the water-cooled lower pressure plate 23, and the water cooling pipe is connected with the electric telescopic sleeve No. 1 22.

[0064] In this embodiment, the water pipe joint is connected to the external hydraulic device, and the No. 1 electric telescopic sleeve 22 is started to extend. The No. 1 electric telescopic sleeve 22 drives the water-cooled lower pressure plate 23 to contact the surface of the sports equipment parts. The No. 1 electric telescopic sleeve 22 can press the surface of the sports equipment parts. At the same time, the water-cooled lower pressure plate 23 water-cools the surface of the sports equipment parts to suppress thermal deformation of the sports equipment parts.

[0065] In a preferred embodiment of the present invention, the control system comprises:

[0066] A monitoring module comprising an infrared thermometer, an infrared imager, and a humidity display, wherein the infrared thermometer and the infrared imager are disposed on the inner top of the connecting sleeve 14, and the humidity display is connected to the outer wall of the connecting sleeve 14;

[0067] a processing module, which is used to receive temperature information from the infrared thermometer, image information from the infrared imager, and humidity information from the humidity display, and the processing module is capable of comparing the above temperature information, image information, and humidity information with corresponding information stored in the processing module itself to form a judgment result;

[0068] The control module can control the drainage device 5, the diversion mechanism 6, the pre-processing device 7 and the thrust mechanism 18 according to the judgment result of the processing module.

[0069] In this embodiment, the infrared thermometer and the infrared imager can monitor the temperature information of the welding part and the stable state of the molten pool, and the humidity display can monitor the humidity information near the welding part.

[0070] By means of an infrared thermometer, an infrared imager and a humidity display, a dynamic adjustment mechanism for welding quality is constructed.
