Description

Technical Field

[0001] The invention relates to the technical field of welding devices, in particular to a clamp used for welding a movable platform of an aerial platform. Background Art

[0002] The aerial work platform is a device used for aerial work. It enables operators to safely reach and stay at heights through a retractable or liftable working platform. The platform on which the aerial work platform stands adopts a curved edge design, which has many advantages over right-angle edges, including improved safety, enhanced stability, optimized work efficiency, improved comfort and aesthetics, and enhanced durability. These advantages have made the curved edge design widely used and recognized in aerial work platform manufacturing.

[0003] The mobile platform of aerial climbing vehicle adopts the design of curved edges. Compared with right-angled edges, the curved design can better adapt to the standing posture of the human body. However, the curved edges need to be constantly adjusted during welding and the welds need to be kept parallel. Conventional welding is difficult. Due to the design of the curved surface, a clamp is required to fix it during welding to avoid deflection during welding. After welding, the remaining welding slag around the weld and the welding marks left by high temperature need to be cleaned.

[0015] Compared with the prior art, the present invention provides a clamp for welding a movable platform of an aerial platform, which has the following beneficial effects:

[0016] 1. Through the mutual cooperation of the cylinder and the arc-shaped clamping ring, the arc edges on both sides of the fence body and the base plate body can be limited to avoid offset during welding, making the welding process more stable. Through the mutual cooperation of the first gear and the clamping teeth, the welding head can always fit the weld on the arc edge and weld, avoiding additional angle adjustment. The translational welding head makes the welding process more efficient, especially in a large-scale production environment, which can significantly improve the welding speed. Through the mutual cooperation of the first electric telescopic rod and the welding head, the welding head can always fit the weld, avoiding manual operation, so that the welding operation can be carried out continuously and stably, reducing the uncertainty and discontinuity of manual operation. The operator only needs to monitor the operating status and welding quality of the equipment, reducing the work intensity.

[0017] 2. Through the cooperation between the second gear and the first rotating rod, the first rotating rod can drive the stirring rod to stir the acid liquid, avoiding acid liquid deposition and affecting the cleaning effect, thereby improving the cleaning quality of the weld and weld mark. Through the cooperation between the push plate and the discharge pipe, the spray head can output acid liquid to the weld to corrode the weld after welding, which can effectively remove the oxide scale, welding slag, rust and other pollutants in and around the weld, making the metal surface smoother and flatter. This is beneficial to improving the quality of subsequent processing, such as cutting, stamping, welding, etc., as well as improving the adhesion and aesthetics of the surface coating. Through the mutual cooperation of the first spring and the inlet hole, continuous output of acid can be avoided, thereby avoiding waste of resources. The mutual cooperation of the first rotating shaft and the second rotating shaft drives the synchronous belt to rotate, so that the frosted surface of the synchronous belt is used to clean the welds after pickling, and the weld marks and other impurities caused by high-temperature welding around the welds are cleaned. Friction cleaning can remove a small amount of acid and other impurities remaining on the metal surface after pickling, ensuring thorough cleaning of the metal surface. The roughness of the metal surface can be increased through friction, which is beneficial to the bonding force between the coating or plating and the metal substrate, and improves the adhesion and durability of the coating.

[0018] 3. Through the mutual cooperation of the sleeve and the second rotating rod, the grinding block can be rotated to carry out targeted cleaning of the welds between the fence body and the base plate body. Comprehensive cleaning of impurities such as welding slag remaining on the weld surface can significantly improve the quality of the weld. Through the mutual cooperation of the convex plate and the third rotating rod, the grinding block can also move up and down when rotating, so that the weld and the surrounding area of the weld can be fully polished, thereby improving the overall quality of the metal surface around the weld, including smoothness, flatness and corrosion resistance.

The mounting block 823 provides an installation space for the acid liquid tank 811. The mounting block 823 is connected to the mounting frame 84 through the connecting plate 812, so that it moves with the mounting frame 84.

[0037] In this embodiment, a stirring rod 813 is fixedly connected to the inside of the outer acid liquid tank 811 of the first rotating rod 810, and a push plate 814 is fixedly connected to the lower part of the stirring rod 813 on the outer side of the acid liquid tank 811.

When the push plate 814 rotates, it will touch and press the discharge pipe 815, causing the discharge pipe 815 to slide in the block 816, and the first spring 819 is pressed by the first limit plate 818, so that the inlet hole 817 and the block 816 are staggered, so that the acid in the acid liquid tank 811 enters the discharge pipe 815 through the inlet hole 817 and is then sprayed onto the weld by the spray head 820 to corrode the weld mark and welding slag.

[0039] In this embodiment, a first spring 819 is provided on the outer side of the discharge pipe 815 , one end of the first spring 819 is fixedly connected to the first limiting plate 818 , and the other end of the first spring 819 is fixedly connected to the acid liquid tank 811 .

[0040] Specifically, after the push plate 814 and the discharge pipe 815 are offset, the tension of the first spring 819 causes the discharge pipe 815 to slide into the stopper 816 , closing the inlet hole 817 .

[0044] Specifically, when the first rotating rod 810 rotates, it drives the third gear 824 to rotate. The third gear 824 drives the fourth gear 826 to rotate through the second chain 825. The fourth gear 826 drives the first rotating shaft 827 to rotate. The first rotating shaft 827 and the second rotating shaft 828 cooperate with each other to drive the synchronous belt 829 to rotate.

[0046] Specifically, the fourth gear 826 drives the fifth gear 92 to rotate through the third chain 91, the fifth gear 92 drives the sleeve 93 to rotate, the sleeve 93 drives the second rotating rod 94 to rotate through the slide bar 95, and the second rotating rod 94 drives the grinding block 97 to rotate to grind the weld, thereby cleaning the weld and the surrounding welding slag. The grinding block 97 is designed as a top cone to adapt to the protrusion of the weld, and while cleaning the weld, the upper and lower positions of the weld are cleaned synchronously.

[0048] Specifically, when the grinding block 97 moves upward, it cooperates with the second limiting plate 96 to squeeze the second spring 98. The tension of the second spring 98 makes the grinding block 97 always fit the protrusion of the weld, thereby cleaning it.

[0049] In this embodiment, two sets of symmetrical third rotating rods 99 are fixedly connected to the outer side of the second rotating rod 94 near the lower end.

[0050] Specifically, the second rotating rod 94 drives the third rotating rod 99 to rotate. When the third rotating rod 99 rotates, the wave-shaped groove height of the convex plate 910 causes the third rotating rod 99 to drive the second rotating rod 94 to slide upward, so that the grinding block 97 moves up and down when it rotates, thereby knocking and rubbing the welding slag, so that the welding slag can be cleaned more comprehensively.

[0051] Working principle: when in use, place the fence body 3 on the upper end of the workbench 1 and then clamp it in the assembly groove 2 for position calibration, then place the base plate body 4 on the upper end of the fence body 3, and align the slider 12 with the groove at the lower end of the base plate body 4. Start the second electric telescopic rod 10, and the output shaft of the second electric telescopic rod 10 drives the arc-shaped support frame 11 to move to both sides of the fence body 3 and align with the inner wall of the fence body 3. The slider 12 slides in the groove at the lower end of the base plate body 4 to align the base plate body 4 with the fence body 3 to avoid offset; the support of the arc-shaped support frame 11 can prevent the fence body 3 from thermal deformation around the weld during welding, start the cylinder 7 installed on one side of the mounting plate 6, and the output shaft of the cylinder 7 drives the arc-shaped retaining ring 81 to move toward the fence body 3, and the arc-shaped retaining ring 81 drives the mounting frame 84, and the mounting frame 84 drives the mounting block through the connecting plate 812 823, the mounting block 823 drives the clamping plate 830 to approach one side of the fence body 3 and the bottom plate body 4, and then starts the first electric telescopic rod 821, and the output shaft of the first electric telescopic rod 821 drives the welding head 822 to fit the weld, and starts the motor 85. The output shaft of the motor 85 drives the first gear 87 to rotate, and the first gear 87 is engaged with the clamping tooth 82, so that the first gear 87 drives the mounting frame 84 to move on the outside of the arc-shaped clamping ring 81. The mounting frame 84 slides on the inner side of the slide groove 83 through the roller 86 to assist the movement of the mounting frame 84 and reduce friction. The mounting frame 84 drives the welding head 822 to move through the first electric telescopic rod 821, thereby welding the weld between the fence body 3 and the bottom plate body 4, and prevents thermal deformation or dislocation between the fence body 3 and the bottom plate body 4 during welding through the clamping of the clamping plate 830;

[0052] After welding is completed, the welding head 822 is closed, and the first electric telescopic rod 821 is started again to move the welding head 822 into the clamping plate 830 and reset, and then the clamping plate 830 is made to fit the weld seam, and the first gear 87 drives the second gear 89 to rotate through the first chain 88, and the second gear 89 drives the first rotating rod 810 to rotate. When the first rotating rod 810 rotates, the liquid inside the acid tank 811 is stirred through the stirring rod 813, and then the push plate 814 is driven to rotate. When the push plate 814 rotates, it touches and The discharge pipe 815 is pressed to slide inside the stopper 816, and the first spring 819 is compressed by the first limit plate 818, so that the inlet hole 817 and the stopper 816 are offset, so that the acid in the acid tank 811 enters the discharge pipe 815 through the inlet hole 817 and is then sprayed onto the weld by the spray head 820 to corrode the weld mark and welding slag. After the push plate 814 and the discharge pipe 815 are offset, the tension of the first spring 819 causes the discharge pipe 815 to slide into the stopper 816, closing the inlet hole 817.

[0053] When the first rotating rod 810 rotates, it drives the third gear 824 to rotate. The third gear 824 drives the fourth gear 826 to rotate through the second chain 825. The fourth gear 826 drives the first rotating shaft 827 to rotate. The first rotating shaft 827 and the second rotating shaft 828 cooperate with each other to drive the synchronous belt 829 to rotate. The synchronous belt 829 rotates and cleans the periphery of the corroded weld through the frosted surface on the outside, so as to clean the discoloration and partial weld marks caused by high temperature around the weld. The fourth gear 826 drives the fifth gear 92 to rotate through the third chain 91. The fifth gear 92 drives the sleeve 93 to rotate.
