For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.

[0029] like Figure 1-7 As shown, a stud welding device is provided, including a support seat 1, a fixed seat 6 is fixedly mounted on the support seat 1, a fixed plate 7 is fixedly mounted on the rear end side of the fixed seat 6, and the plate surface of the fixed plate 7 is in a vertical direction. A clamping tool 5 is fixedly mounted on the fixed seat 6, and the clamping tool 5 is used to clamp the studs and parts to be welded. It should be noted that the clamping tool 5 is a prior art, so this embodiment will not be described in detail.

[0030] A welding tool is fixedly mounted on the fixing plate 7, and the welding tool is used to weld the studs and parts. Figure 1 and 2 As shown, the welding fixture includes a cylinder 4, a slide bar, a slide bar fixing block, a slider and a welding electrode 3; the two ends of the slide bar are fixedly connected to the slide bar fixing block, the slide bar fixing block is fixedly mounted on the fixing plate 7, the slider and the slide bar are slidably connected, the output end of the cylinder 4 passes through the slide bar fixing block and is fixedly connected to the slider, and the welding electrode 3 is fixedly mounted on the slider. Therefore, the welding electrode 3 can slide in the vertical direction, and the welding electrode 3 is above the clamping fixture 5 and the two are matched, that is, the position of the welding electrode 3 is directly above the welding point between the stud and the component.

[0031] A power source 2 is provided inside the support seat 1. When the power source 2 is started, the welding electrode 3 first provides a small current, and then the stud contacts the workpiece, and an arc is established between the tip of the stud and the workpiece. After the arc is established, the welding electrode 3 automatically enters high-current welding, the end of the stud begins to melt, and the workpiece forms a molten pool. When the set welding time is reached, the arc is extinguished, and the stud is immersed in the molten pool during the downward pressing process of the welding electrode 3. After natural cooling, the welding process is completed.

[0032] The left and right ends of the fixing seat 6 are both fixedly connected with support plates 10, wherein the support plates 10 are placed horizontally; a receiving groove 11 is provided inside the support plate 10, and a protection component is hingedly connected to one end of the receiving groove 11 close to the fixing seat 6. Therefore, both sides of the welding area have protection components, and the left and right sides of the welding area can be protected by the protection components during welding.

[0033] Specifically, the protection assembly includes a rotating shaft 12, a side plate 13 and an extension plate 14. The size of the side plate 13 matches the size of the receiving slot 11, and one end of the side plate 13 is rotatably connected to the receiving slot 11 through the rotating shaft 12. When the side plate 13 rotates to a vertical direction, the side plate 13 protects the welding area, and when the side plate 13 rotates to a horizontal direction, the side plate 13 can be stored in the receiving slot 11. Further, as Figure 3 and 4 As shown, a docking block 18 is fixedly connected to the side panel 13, and docking grooves 19 are provided on both sides of the fixed plate 7. The docking grooves 19 and the docking blocks 18 cooperate with each other. Therefore, when the side panel 13 is rotated to a vertical direction for protection, the position of the fixed side panel 13 can be limited by the docking blocks 18 being inserted into the docking grooves 19.

[0034] Furthermore, in order to increase the protection height, an extension plate 14 is provided, specifically, as Figure 5 and 6 As shown, the extension plate 14 is inside the side plate 13 and the two are slidably matched. The length of the side plate 13 is greater than that of the extension plate 14. The side plate 13 and the extension plate 14 are symmetrically distributed about the longitudinal center line of the fixing seat 6. A positioning assembly is connected between the extension plate 14 and the side plate 13. The positioning assembly is symmetrically arranged on both sides of the extension plate 14. The positioning assembly includes a first spring 15 and a clamping block 16. The extension plate 14 is provided with a positioning groove. One end of the first spring 15 is fixedly connected to the bottom of the positioning groove. The other end of the first spring 15 is fixedly connected to the clamping block 16. One end of the clamping block 16 is inside the positioning groove, and the other end of the clamping block 16 is outside the positioning groove. Clamping grooves 17 are equidistantly provided on both sides of the side plate 13. The clamping grooves 17 and the clamping blocks 16 match each other. When the side plate 13 is rotated to the vertical direction for protection, the extension plate 14 can be pulled to slide inside the side plate 13, thereby adjusting the protection height, and then the position of the extension plate 14 is locked by the positioning assembly.

[0035] The interior of the fixed seat 6 is provided with a slide groove 20, the slide groove 20 is connected with a telescopic component, the telescopic component is connected with a protective plate 8, the protective plate 8 is located at the front end side of the fixed seat 6, and the plate surface of the protective plate 8 is in a vertical direction. Figure 7 As shown, the telescopic assembly includes a second spring 21 and a support rod 22. One end of the second spring 21 is fixedly connected to the bottom of the chute 20, the other end of the second spring 21 is fixedly connected to one end of the support rod 22, and the other end of the support rod 22 is fixedly connected to the protective plate 8. The protective plate 8 includes a fixedly connected glass plate 9 and a frame. Through the glass plate 9, the welding process can be viewed in real time. The support rod 22 is an L-shaped rod, and the L-shaped wide end of the support rod 22 is outside the chute 20 and fixedly connected to the frame. By pulling the support rod 22, the position of the protective plate 8 can be adjusted under the action of the second spring 21 to prevent the protective plate 8 from affecting the clamping work of the clamping fixture 5 on the workpiece or stud.

[0036] In summary, a safe welding area is formed by the fixing plate 7 on the rear end side, the protective components on the left and right ends, and the protective plate 8 on the front end side, which can effectively avoid the risk of personal injury to the staff caused by flying sparks. In addition, a fan 23 is arranged inside the support seat 1, and the air inlet of the fan 23 is connected to the welding area. When the fan 23 is working, the welding gas (which may contain harmful gases) in the welding area can be sucked away in time; therefore, the components on the four sides of the welding area can block the external wind force, slow down the diffusion speed of the welding gas (which may contain harmful gases), and facilitate the fan 23 to collect the welding gas (which may contain harmful gases) in a centralized manner.

[0037] The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any technician familiar with the field can make many possible changes and modifications to the technical solution of the utility model by using the above disclosed methods and technical contents without departing from the scope of the technical solution of the utility model, or modify it into an equivalent embodiment of equivalent changes. Therefore, all equivalent changes made according to the shape, structure and principle of the utility model without departing from the content of the technical solution of the utility model should be included in the protection scope of the utility model.
