Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically to an automatic welding device for excavator bucket side plates. Background Technology

[0002] Bucket side plates are vertical plate-like components that form the sides of the bucket. They play a crucial role in the structural strength and functionality of the bucket. Bucket side plates are usually located on both sides of the bucket and are symmetrically distributed. Their lower ends are generally connected to the cutting edge where the bucket teeth are located, and they extend vertically upwards to the top of the bucket. Together with the back plate, bucket main plate, etc., they form the inner cavity of the bucket, which is used to hold the excavated material. At the same time, during the excavation, loading and unloading process, they bear the lateral pressure and friction of the material, ensuring the structural integrity of the bucket and preventing material leakage from the side.

[0003] Because the bucket needs to withstand the impact, compression and friction of materials during operation, the side plates of the bucket are welded during manufacturing. This provides the side plates with a connection strength far exceeding that of bolts or rivets. When welding smaller side plates, workers usually place the side plates on the ground and then manually splice and attach them. Then, they use a handheld welding gun to weld the side plates. After welding one side, when welding the other side, it is also necessary to manually rotate it. Therefore, this welding method is inefficient and cumbersome. Utility Model Content

[0004] To overcome the above-mentioned defects, embodiments of this utility model provide an automatic welding device for bucket side plates, which solves the technical problem that manual welding is inefficient and cumbersome when welding small side plates in the prior art.

[0005] According to one aspect, at least one embodiment of the present invention provides an automatic welding device for bucket side plates, including a support platform, a welding mechanism mounted on the support platform, a rotating ladder, a shelf, a support plate, a ladder support assembly, and a pressing and fixing assembly. The rotating ladder is rotatably mounted on the support platform via a flip shaft, and a motor connected to the flip shaft is mounted on the support platform. The shelf is fixedly mounted on the rotating ladder for placing the side plate, and the support plate supporting the side plate is fixedly mounted on the side of the shelf. Two ladder support assemblies are provided and are located on the support platform for supporting the rotating ladder after rotation. Two pressing and fixing assemblies are provided, both of which are located on the shelf for pressing and fixing the side plate placed on the support plate.

[0006] Furthermore, the platform support assembly includes a sliding rod, a U-shaped pusher, support blocks, and a drive assembly. There are two sliding rods, both of which are slidably mounted on the upper surface of the support platform. The U-shaped pusher is fixedly mounted on the top ends of the two sliding rods. Two support blocks are fixedly mounted on the sides of the U-shaped pusher. The drive assembly is mounted on the support platform.

[0007] Furthermore, the drive assembly includes a first electric cylinder and a pusher frame. The first electric cylinder is horizontally mounted on the support platform, one end of the pusher frame is fixedly mounted on the output end of the first electric cylinder, and the other end of the pusher frame is fixedly mounted on the side of the U-shaped pusher frame.

[0008] Furthermore, the pressing and fixing assembly includes a reciprocating lead screw, a crescent-shaped slider, and a pressing assembly. The reciprocating lead screw is rotatably mounted on the upper surface of the rotating platform via two mounting plates, and a first motor is mounted on the side of one of the mounting plates. The output end of the first motor is coaxially connected to the reciprocating lead screw. The crescent-shaped slider is mounted on the reciprocating lead screw, and the pressing assembly is disposed on the crescent-shaped slider.

[0009] Furthermore, the pressing assembly includes a placement plate, a second electric cylinder, and a U-shaped pressing frame. The placement plate is fixedly installed on the crescent-shaped slider, the second electric cylinder is installed on the placement plate, and the U-shaped pressing frame is fixedly installed with the output end of the second electric cylinder.

[0010] Furthermore, a groove is provided on the upper surface of the rotating platform, a limit block is slidably installed in the groove, and the top end of the limit block is fixedly connected to the bottom end of the crescent-shaped slider.

[0011] Furthermore, a pressure plate is vertically fixedly installed at the inner top of the U-shaped pressure frame.

[0012] Furthermore, the support block has an L-shaped support groove on its side, and when the rotating platform rotates to a horizontal position, the L-shaped support groove fits into the side of the rotating platform.

[0013] The beneficial effects of this utility model are as follows: In this invention, when welding the side panel, the worker first places the side panel on the support plate of the shelf, thus placing the side panel horizontally. Then, the pressing and fixing components press down and fix both sides of the side panel, thereby driving the welding mechanism to weld the surface of the side panel. After the upper surface is welded, the rotating platform is rotated 180 degrees to rotate the other side of the side panel to the top. Then, the welding mechanism is used again to weld the side panel. After welding is completed, the worker wearing protective gloves removes the side panel. This method can clamp and fix the placed side panel and can rotate it to weld both sides in sequence, which is more labor-saving and improves welding efficiency. Attached Figure Description

[0022] like Figures 1-4As shown, this invention illustrates an automatic welding device for bucket side plates according to one embodiment of the present invention. The device includes a support platform 1, on which a welding mechanism 2 is mounted. It also includes a rotating platform 3, a shelf 4, a support plate 5, a platform support assembly, and a pressing and fixing assembly. The rotating platform 3 is rotatably mounted on the support platform 1 via a tilting shaft, and a motor connected to the tilting shaft is mounted on the support platform 1. The shelf 4 is fixedly mounted on the rotating platform 3 for placing the side plates. A support plate 5 supporting the side plates is fixedly mounted on the side of the shelf 4. Two platform support assemblies are provided and mounted on the support platform 1 to support the rotating platform 3 after rotation. Two pressing and fixing assemblies are provided, both mounted on the shelf 4, for pressing and fixing the side plates placed on the support plate 5.

[0023] like Figure 2 As shown, when welding the side plate, the two ends of the side plate are first placed on the two support plates 5 of the shelf 4 respectively. At this time, the middle part of the side plate is located in the middle gap of the shelf 4. The rotating platform 3 is placed horizontally. The bottom of the rotating platform 3 can be supported by the platform support assembly. The platform support assembly includes a sliding rod 6, a U-shaped pusher 7, a support block 8 and a drive assembly. There are two sliding rods 6, and both sliding rods 6 are slidably installed on the upper surface of the support platform 1. The U-shaped pusher 7 is fixedly installed on the top of the two sliding rods 6. Two support blocks 8 are fixedly installed on the side of the U-shaped pusher 7. The drive assembly is set on the support platform 1. The drive assembly includes a first electric cylinder 9 and a pusher 10. The first electric cylinder 9 is horizontally installed on the support platform 1. One end of the pusher 10 is fixedly installed on the output end of the first electric cylinder 9, and the other end of the pusher 10 is fixedly installed on the side of the U-shaped pusher 7.

[0024] Specifically, the first electric cylinder 9 is activated, and the output end of the first electric cylinder 9 drives the pusher 10 to move forward. The pusher 10 pushes the U-shaped pusher 7 and the two support blocks 8 to move forward. Because the side of the support block 8 is provided with an L-shaped support groove, and when the rotating platform 3 rotates to the horizontal position, the L-shaped support groove fits against the side of the rotating platform 3, pushing the support block 8 until the L-shaped support groove fits against the bottom of the rotating platform, thereby supporting it.

[0025] like Figure 3 and Figure 4As shown, after the support is completed, the side plate of the part placed on the support plate 5 is pressed down and fixed by the pressing and fixing assembly. The pressing and fixing assembly includes a reciprocating screw 11, a crescent slider 14 and a pressing assembly. The reciprocating screw 11 is rotatably mounted on the upper surface of the rotating platform 3 through two mounting plates 12, and a first motor 13 is mounted on the side of one of the mounting plates 12. The output end of the first motor 13 is coaxially connected to the reciprocating screw 11. The crescent slider 14 is mounted on the reciprocating screw 11. The pressing assembly is set on the crescent slider 14. The pressing assembly includes a placement plate 15, a second electric cylinder 16 and a U-shaped pressing frame 17. The placement plate 15 is fixedly mounted on the crescent slider 14, the second electric cylinder 16 is mounted on the placement plate 15, and the U-shaped pressing frame 17 is fixedly mounted to the output end of the second electric cylinder 16.

[0026] Specifically, starting the first motor 13 causes the output of the first motor 13 to drive the reciprocating screw 11 to rotate, thereby causing the crescent-shaped slider 14 to move left and right on the reciprocating screw 11. Because the upper surface of the rotating platform 3 is provided with a groove, and a limit block is slidably installed in the groove, and the top of the limit block is fixedly connected to the bottom of the crescent-shaped slider 14, the crescent-shaped slider 14 can move horizontally on the reciprocating screw 11. The crescent-shaped slider 14 then drives the placement plate 15 to move synchronously until the U-shaped lower pressure frame 17 is above the side plate. Because the inner top of the U-shaped lower pressure frame 17 is vertically fixedly installed with a lower pressure plate 18, when the output of the second electric cylinder 16 is started to drive the U-shaped lower pressure frame 17 to move downward, the U-shaped lower pressure frame 17 can move horizontally. The lower pressure frame 17 and the lower pressure plate 18 have more contact with the side plates. After the lower plate is moved down, it is pressed. It should be added that the shape design of the crescent slider 14 matches the helical groove of the reciprocating screw 11. When the reciprocating screw 11 rotates, the side wall of the helical groove will generate an axial thrust on the crescent slider 14 embedded therein. The crescent slider 14 can move along the axial trajectory of the reciprocating screw 11, thereby moving left and right. When the crescent slider 14 reaches the end of the reciprocating screw 11, the crescent slider 14 will smoothly transition to the reverse helical groove, thereby realizing reciprocating movement. This is a well-known technology and will not be described in detail. Furthermore, a telescopic protective sleeve can be installed on the outside of the reciprocating screw 11 to protect it.

[0027] After the fixing is completed, the welding mechanism 2 is started to weld the upper surface of the side plate. After the welding is completed, the support block 8 is first removed and moved away from the rotating platform 3. Then the motor is started to drive the rotating platform 3 to rotate 180 degrees, rotating the other side of the side plate to the top, and then fixing it. Then the welding is carried out again.

[0028] Working principle: When welding the side plates, the rotating platform 3 is first rotated to a horizontal position. Then, the first electric cylinder 9 is activated. The output end of the first electric cylinder 9 drives the pusher 10 to move forward. The pusher 10 pushes the U-shaped pusher 7 and the two support blocks 8 forward. Because the side of the support block 8 has an L-shaped support groove, and when the rotating platform 3 is rotated to a horizontal position, the L-shaped support groove fits against the side of the rotating platform 3. The support block 8 is pushed until the L-shaped support groove fits against the bottom of the rotating platform, thus supporting it. After the support is completed, the first motor 13 is activated. The output of the first motor 13... The output end drives the reciprocating screw 11 to rotate, thereby causing the crescent slider 14 to move left and right on the reciprocating screw 11. The crescent slider 14 moves horizontally on the reciprocating screw 11, thus driving the placement plate 15 to move synchronously. When the U-shaped pressing frame 17 is located above the side plate, because the inner top of the U-shaped pressing frame 17 is vertically fixed with the pressing plate 18, when the output end of the second electric cylinder 16 is activated to drive the U-shaped pressing frame 17 to move down, more of the side plate can contact the U-shaped pressing frame 17 and the pressing plate 18. After the downward movement is completed, it is pressed.

[0029] After pressing is completed, the workers move away from the support platform 1 and start the welding mechanism 2. It should be noted that the welding mechanism 2 includes a robotic arm and a welding torch. The welding torch is mounted on the robotic arm and is connected to the welding power source and laser generator. The welding torch is driven by the robotic arm and moves according to the speed set by the program. It can also CNC move to the center of the weld. The sensor can monitor the arc voltage and the temperature of the molten pool in real time, thereby welding the side plate.

[0030] After welding one side of the side plate is completed, the support block 8 is moved away from the rotating platform 3. Then the rotating platform 3 is rotated so that the side plate rotates 180 degrees and the other side is rotated to the top. Then the support block 8 is driven to support the rotating terrace. Then the welding of the other side continues. After the welding is completed, the staff wears protective clothing and takes it down.

[0031] It should also be noted that the power sources of the first motor 13, the first electric cylinder 9, and the second electric cylinder 16 are all consistent with the power source of the welding mechanism 2, and can be powered by the power supply inside the factory building. Furthermore, the welded sides can be placed on the two support plates 5.

[0032] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
