Description

Technical Field

[0001] The invention belongs to the technical field of guardrail welding, and in particular relates to a high-precision welding device for processing stainless steel special-shaped guardrails. Background Art

[0002] Stainless steel guardrails are protective and decorative fencing systems made of 304 or 316 stainless steel as the main material through cutting, bending, welding and polishing processes. Due to their corrosion resistance, high strength, beautiful and durable features, they are widely used in construction, municipal administration, transportation, home and industry. Among them, some guardrails have special-shaped curved crossbars to meet different requirements. When processing them, corresponding welding equipment is required.

[0003] The document with publication number CN113770610A discloses a guardrail welding device, including a machine platform, a first conveyor path arranged on the machine platform, a second conveyor path arranged on the machine platform and parallel to the first conveyor path, a third conveyor path arranged on the machine platform and perpendicular to the first conveyor path, a welding gun arranged above the machine platform, a welding positioning device, and a pushing device, wherein the welding positioning device includes a positioning material box connected to the third conveyor path, a first pushing assembly and a second pushing assembly located next to the positioning material box, and a pushing assembly located below the positioning material box. The invention provides a guardrail welding device, a welding gun, a welding positioning device, and a pushing assembly. After the position is debugged, it is fixed and the metal pipe to be welded moves forward in steps. The joint of the metal pipe to be welded is close to the fixed welding gun, thereby realizing the welding of the guardrail, replacing the manual method of welding the guardrail with a handheld welding gun. The welding operation ensures the welding effect, improves the welding precision, and improves the safety performance. However, when welding special-shaped guardrails, since the cross bar of the special-shaped guardrail is not a common straight bar, it will have multiple curvatures.

[0051] Working principle: When in use, the staff installs the two stainless steel special-shaped cross bars on the adjustment fitting component 6. Before that, the staff adjusts the relative heights between the multiple connecting groove seats 607 according to the curvature of the stainless steel special-shaped cross bars. The staff drives the lifting sleeve 605 to move through the lifting push rod 603 according to actual requirements. The lifting sleeve 605 drives the connecting groove seat 607 to move through the connecting slider 606, so that the connecting groove seat 607 can adapt to the curvature of the stainless steel special-shaped cross bar and make the stainless steel special-shaped cross bar between the two connecting frames 609. Afterwards, the staff rotates the forward and reverse screws 611, and the forward and reverse screws 611 drive the two lifting plates 608 to move relative to each other through the screw seat 612, and make the two lifting plates 608 drive the two fitting friction wheels 610 to be relatively close through the connecting frame 609, and the fitting friction wheels 610 gradually fit the outer surface of the stainless steel special-shaped cross bar, and And because the stainless steel special-shaped cross bar itself has curvature, usually one of the fitting friction wheels 610 on the connecting frame 609 first fits with the surface of the stainless steel special-shaped cross bar, and then the fitting friction wheel 610 drives the connecting frame 609 to deflect around the fixed column 616 under the pressure of the stainless steel special-shaped cross bar, so that the fitting friction wheel 610 on the other side can fit with the surface of the stainless steel special-shaped cross bar through the lever principle. In this process, the support spring 615 cooperates with the movable rod 613 to provide lateral support for the connecting frame 609 and the fitting friction wheel 610, so that it can adapt to the surface curvature of the stainless steel special-shaped cross bar and improve the stability during welding. After completing the installation limit of the stainless steel special-shaped cross bar, the staff starts the adjustment push rod 602, and the adjustment push rod 602 drives the traveling plate 601 to move relative to each other, thereby changing the distance between the two stainless steel special-shaped cross bars to meet different welding processing requirements.

[0052] After the first screw is screwed in, the second screw is screwed in. The first screw is screwed in, and the second screw is screwed in. After the first screw is screwed in, the second screw is screwed in. The first screw is screwed in, and the second screw is screwed in. During the resetting process of the flip plate 704, the limiting wheel 708 can squeeze and limit the other side of the vertical rod. Due to the setting of the limiting wheel 708, the limiting wheel 708 can better adapt to the outer surface of the vertical rod. At the same time, the pressure of the vertical rod will act on the limiting wheel 708, and the limiting wheel 708 drives the first spring 707 to compress. Through the flexible displacement of the limiting wheel 708, the clamping slot seat 701 can be suitable for welding vertical rods of different specifications, which improves the flexibility of the device. After completing the installation axis of the vertical rod, the staff rotates the accompanying rotating cylinder 801, and then repeats the above operation to complete the preparation and storage of multiple vertical rods.

[0053] After completing the installation of the stainless steel special-shaped horizontal bar and vertical bar, the staff starts the linear module 2 and the welding robot 5 to start welding. During this process, the linear module 2 drives the movable bracket 4 to move, and the movable bracket 4 moves synchronously through the connecting block 802 and the accompanying rotating cylinder 801. When it moves to the welding point, the fixed push rod 811 drives the pushing plate 810 to move upward, and the pushing plate 810 gradually moves toward the bonding plate 808 just above, so that the bonding plate 808 can move upward, and the bonding plate 808 drives the lifting rod 806 to move upward, and the lifting rod 806 drives the vertical rod to move upward to the appropriate position through the clamping blanking component 7, so that the two ends of the vertical rod can fit with the side of the stainless steel special-shaped horizontal bar. After that, the welding robot 5 welds the welding point. After completing the welding, the movable bracket 4 moves under the drive of the linear module 2, and the movable bracket 4 drives the accompanying rotating cylinder 801 to move, and the accompanying rotating cylinder 801 passes After the first welding rod 701 is welded to the welding point, the fixed push rod 811 returns to its original position and the previous bonding plate 808 is reset under the drive of the second spring 807. After that, the adjustment motor 803 drives the driving gear 804 to rotate, and the driving gear 804 drives the driving gear ring 805 to rotate, and the driving gear ring 805 drives the accompanying rotating cylinder 801 to rotate, and drives the next vertical rod to rotate to the top of the fixed push rod 811 through the lifting rod 806 and the clamping and blanking assembly 7. After that, the fixed push rod 811 moves the vertical rod to the appropriate position and continues the welding operation. The adjustment motor 803 is a motor with a self-locking function.
