[0034] The embodiment of the utility model provides a gas shielded welding device for welding a steering tube, which can dock and clamp multiple workpieces constituting the steering tube during the welding process, thereby facilitating welding of the docked and fixed workpieces to be welded.

[0035] like Figure 2-6 As shown, the embodiment of the present invention provides a steering tube gas shielded welding device, including a welding tool 200 and a gas shielded welding robot 100 for welding, as shown in FIG. Figure 2-4 The welding tool 200 shown includes a flip positioner 201 and a clamping mechanism 210 fixedly mounted on the flip positioner 201. The clamping mechanism 210 is used to clamp and fix the various workpieces constituting the steering tube and align them with each other, thereby facilitating welding of the workpieces to be welded. When the flip positioner 201 is flipped, the side of the clamping mechanism 210 can be rotated upward to facilitate welding of the side of the workpiece to be welded. The clamping mechanism 210 includes a base plate 211, a first support member 212, a second support member 215, and a pressing fixture 200. The first support member 212 is fixedly mounted on the base plate 211, and includes a plurality of first support rods 213 arranged side by side and vertically. A groove for placing the first support rods 213 is provided on the end of the first support rods 213. 214; the second support member 215 is also fixedly set on the base plate 211 and corresponds to any one of the first support rods 213, and includes two second support rods 216 respectively located on both sides of the first support rod 213, and a supporting surface 217 is provided on the top of the second support rod for adapting to the workpiece to be welded; a pressing fixture 200 is fixedly installed on the supporting surface 217, and the pressing fixture 200 includes a base 221 fixedly installed on the end of the second support rod, on which a toggle rod 222 and a clamping arm 223 are rotatably connected, and the rotating axes of the toggle rod 222 and the clamping arm 223 are parallel to each other, and the pressing fixture 200 also includes a connecting rod 224, one end of the connecting rod 224 is rotatably connected to the middle section of the toggle rod 222, and the other end is rotatably connected to the middle section of the clamping arm 223.

[0036] During the process of clamping and fixing the workpiece, the pipe column 10 constituting the steering tube is placed in the placement groove 214 on the first support rod 213. At the same time, the crossbeam 13 is placed horizontally on the pipe column 10 and is pressed downward by the pressing fixture 200 set on the second support rod 216, so that the crossbeam 13 and the pipe column 10 are docked with each other and pressed, so that the robot 100 can weld the docking seam between the crossbeam 13 and the pipe column 10.

[0037] When the clamp 200 is pressed down to compress the beam 13 and the pipe column 10, Figure 4-5 As shown, the toggle rod 222 drives the clamping arm 223 to flip through the connecting rod 224, so that the free end of the clamping arm 223223 moves downward, and then presses the pipe column 10 located on the first support rod 213 downward into the placement groove 214. During the pressing process, when the toggle rod 222 and the connecting rod 224 are in the same straight line, the connecting rod 224 and the toggle rod 222 are in the dead point position, thereby maintaining the clamping state of the clamping arm 223, ensuring that the beam 13 and the pipe column 10 are tightly connected to each other.

[0038] In this embodiment, if Figure 2-4 As shown, the clamping mechanism 210 also includes a rear side plate 218, which is used to clamp the connecting plate 11 constituting the steering tube and align it with the column 10. The rear side plate 218 is fixedly mounted on the bottom plate 211 and is arranged on the rear side of the first support member 212 along the side-by-side direction of the first support rod 213. At least one pressing clamp 200 is fixedly mounted on the rear side plate 218 to press in the direction of the rear side plate 218.

[0039] During the welding process of the steering tube, the connecting plate 11 is clamped on the rear side plate 218 by the pressing clamp 200 fixedly installed on the rear side plate 218. At the same time, the connecting plate 11 and the pipe column 10 pressed on the first support rod 213 are docked with each other to facilitate the welding of the docking seam between the connecting plate 11 and the pipe column 10.

[0040] In this embodiment, to securely connect the connecting plate 11 and the pipe string 10 and ensure a good welding effect between the connecting plate 11 and the pipe string 10, the first support member 212 further includes a third support rod 219. The third support rod 219 is arranged in a parallel direction with the first support rod 213 and in front of the first support rod 213. A push assembly 230 is fixedly supported at the end of the third support rod 219. The push assembly 230 includes a push rod 231 and a push drive device 232 that is transmission-connected to the push rod 231 and drives the push rod 231 to reciprocate along a straight line toward the rear side plate 218. In this embodiment, the first support rod 213 and the third support rod 219 are integrally formed, thereby forming a single unit of the first support member 212 and ensuring sufficient strength. In particular, when the push assembly 230 pushes the pipe string 10 toward the rear side plate 218, the third support rod 219 does not wobble or move slightly, thereby ensuring tight contact between the pipe string 10 and the connecting plate 11.

[0041] In this embodiment, a positioning platform 2131 is formed on the end of any one of the first support rods 213, which is adapted to the hole position on the pipe column 10, thereby positioning the pipe column 10 to prevent the pipe column 10 from rotating and affecting the stability of the clamping positioning; at the same time, a supporting platform 2132 is also formed on the side wall of the first support rod 213, and the supporting platform 2132 is located on the lower side of the placement groove 214, which is used to support the ear 12. In the process of clamping and fixing the pipe column 10, one end of the ear 12 is placed on the supporting platform 2132, and the other end is against the side wall of the pipe column 10, so that the ear 12 is clamped and fixed by the supporting platform 2132 and the pipe column 10, and the welding robot 100 facilitates welding of the joint between the ear 12 and the pipe column 10. Example

[0042] In this embodiment, the structure of the welding tool 200 is the same as that described above. This embodiment provides a specific example of the structure of the driving device 232, such as Figure 4 、 6 As shown, the pushing drive device 232 includes a base 233, an active stem and an intermediate rod 236, wherein the base 233 is fixedly mounted on the end of the third support rod 219, and a through hole 234 is provided on the base 233 for the pushing rod 231 to be slidably connected therein; the active rod 235 is arranged on the rear side of the pushing rod 231 along the axial direction of the pushing rod 231, and one end of the active rod 235 is rotatably connected to the base 233, and the other end constitutes a handheld end for driving the active rod 235 to swing along the rotating axis; one end of the intermediate rod 236 is rotatably connected to the middle section of the active rod 235, and the other end is rotatably connected to the end of the pushing rod 231 facing the active rod 235.

[0043] In this embodiment, the pushing drive device 232 is set as a crank slider mechanism, and the pushing rod 231 is driven by the crank slider mechanism, so that it can achieve reciprocating movement toward the rear side plate 218, and then push the pipe column 10 toward the rear side plate 218. The driving method of the crank slider mechanism is simple and reliable, and it is not easy to loosen after pushing, and the clamping effect is reliable.

[0044] The embodiment of the present invention provides a steering tube gas shielded welding device, which uses a downward pressing fixture 200 to press and fix the crossbeam 13 and the pipe column 10 on the first support rod 213. At the same time, the pipe column 10 and the support platform press the ear 12, and under the push of the pushing component 230, the pipe column 10 is docked with the connecting plate 11 clamped and fixed on the rear side plate 218 and tightly abuts against each other. Through the above structure, multiple workpieces to be welded constituting the steering tube are fixed and aligned, so that the welding robot 100 can facilitate welding the butt joints between the workpieces, thereby avoiding the situation of manual docking and fixing during the steering tube welding process, ensuring the accuracy and quality of welding, and improving welding efficiency.
