DETAILED DESCRIPTION

[0021] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Example:

[0023] like Figure 1 As shown, the workpiece for the arc-shaped steel component welding tool of the utility model includes two arc-shaped arc plates 6 and two connecting plates 7 located between the arc plates 6. The joint between the connecting plate 7 and the arc plate 6 is the welding point. The connecting plate 7 and the arc plate 6 can be connected as a whole by welding to form a steel component.

[0024] like Figure 2-Figure 4 As shown, the utility model provides an arc-shaped steel member welding tool, including a conveying mechanism 1 and a welding mechanism arranged above the conveying mechanism 1. The conveying mechanism 1 adopts common roller conveying, and the workpiece can be placed on the surface of the roller and conveyed forward under the rotation of the roller. The welding mechanism includes a guide mechanism, a welding gun 3, a slide rail 4 and a slider 5 matched with the slide rail 4. It also includes a frame 14, which is in a door shape. The slide rail 4 is arranged perpendicular to the conveying direction of the conveying mechanism 1, and its two ends are connected to the two sides of the frame 14. The guide mechanism is connected to the slider 5 and is provided with a guide member 2 for clamping the workpiece, so that the guide member 2 moves along the slide rail 4 with the workpiece. The guide member 2 is arranged in a U shape and is matched with the arc plate 6, so that the top of the arc plate 6 can be inserted into the inside of the guide member 2. Rollers 8 are arranged on both sides of the inside of the guide member 2. When the workpiece moves forward, the guide of the roller 8 prevents the guide member 2 from being stuck. At the same time, the cooperation between the guide member 2 and the arc plate 6 makes the guide member 2 move along the slide rail 4 when the workpiece moves along the slide rail 4. The slide block 5 is then driven to slide along the slide rail 4. The welding gun 3 is disposed on the slide block 5 so that the welding gun 3 moves along with the slide block 5.

[0025] When the arc-shaped steel component welding tool of the utility model is used, the workpiece is placed on the conveying mechanism 1, and then the workpiece is gradually conveyed forward by the conveying mechanism 1. When the workpiece passes under the welding gun 3, the welding gun 3 welds the part to be welded. Since the workpiece is arc-shaped, and the conveying mechanism 1 is a straight conveying. This makes the welding position of the workpiece constantly change in front of the welding gun 3. In order to adapt to this change, the welding gun 3 changes with the welding position of the workpiece. Specifically, when the welding position of the workpiece changes along the conveying direction perpendicular to the conveying mechanism 1, it will drive the guide member 2 to change synchronously with the workpiece. This makes the slider 5 and the welding gun 3 change position along the slide rail 4. Since the welding gun 3 is set to point to the welding position at the beginning, the welding gun 3 always points to the position to be welded during the process of following the change of the workpiece. Therefore, it can adapt to the welding of arc-shaped workpieces.

[0026] In this embodiment, the guide member 2 is further provided with a swing member 9. Figure 3 As shown, the swing member 9 is rotatably connected to the lower part of the slider 5 so that the swing member 9 can rotate in a horizontal plane. A connecting rod 10 connected to the welding gun 3 is extended from the lower part of the slider 5. The swing member 9 is provided with a through hole for the connecting rod 10 to pass through. The connecting rod 10 extends downward through the through hole and then connects to the welding gun 3. The swing member 9 is also provided with a top screw 11 in conjunction with the connecting rod 10. One end of the top screw 11 is exposed outside the swing member 9, and the other end extends into the inside of the swing member 9 so that the top screw 11 can press the connecting rod 10. When the top screw 11 presses the connecting rod 10, the swing member 9 is locked and cannot rotate relative to the slider 5. After the top screw 11 is loosened, the swing member 9 can swing arbitrarily. The guide member 2 is connected to the end of the swing member 9 away from the slider 5.

[0027] This allows the swing member 9 to rotate and drive the guide member 2 to rotate around the slider 5. As shown in question 2, the guide member 2 is located on the left side of the workpiece. After the left side welding is completed, the swing member 9 is rotated to move the guide member 2 to the right side of the workpiece, and then cooperate with the arc plate 6 on the right side, and then cooperate with the welding process on the right side.

[0028] In this embodiment, the guide member 2 is also provided with an adjusting rod 12. The guide member 2 is connected to the bottom end of the adjusting rod 12. The adjusting rod 12 is a screw rod. The end of the swing member 9 away from the slider 5 is provided with a screw hole in cooperation with the screw rod. This allows the adjusting rod 12 to be turned and its downward extension length to be adjusted. This allows the guide member 2 to adapt to arc plates 6 of different heights. The screw rod is also provided with a locking nut 13. When the height of the guide member 2 is adjusted, the locking nut 13 is tightened to the swing member 9, which prevents the screw rod from rotating, thereby locking the screw rod, and also locking the guide member 2.

[0029] In this embodiment, both ends of the slide rail 4 are movably connected to the two sides of the frame 14, so that the slide rail 4 can be lifted and lowered along the frame 14. This allows the welding gun 3 and the guide member 2 to be lifted and lowered along with the slide rail 4, thereby better adapting to workpieces of different sizes.

[0030] In this embodiment, guide wheels 15 are provided on both sides of the frame 14. The gap between the guide wheels 15 on both sides is set to match the width of the workpiece, so that the two guide wheels 15 are respectively in contact with one side of the workpiece. The workpiece is limited by the guide wheels 15, so that the amplitude of the workpiece shaking along the direction of the slide rail 4 is limited when the workpiece moves with the conveying mechanism 1, thereby preventing the welding gun 3 from shaking too much, and ensuring the relative position stability between the welding gun 3 and the workpiece.

[0031] In this embodiment, the guide wheel 15 is provided with a guide rod 16. The guide rod 16 is slidably arranged on the frame 14. A tension spring 17 is also sleeved on the outside of the guide rod 16. The tension spring 17 presses the guide wheel 15 against the workpiece. At the same time, when the workpiece shakes left and right, the guide wheel 15 is squeezed, so that the tension spring 17 performs buffering. This makes the guide wheel 15 more gentle in restricting the left and right directions of the workpiece.

[0032] In this embodiment, two sets of guide wheels 15 are provided on both sides of the frame 14 to match the workpiece, and the two guide wheels 15 on each side are arranged at intervals. The two guide wheels 15 on each side make the width of the restriction on one side of the workpiece wider, so that the distance and angle of the workpiece that can be deflected after being restricted by the guide wheels 15 are smaller, thereby better ensuring the welding quality.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
