Description

Technical Field

[0001] The invention relates to the field of welding tools, and more specifically, to an automatic welding platform. Background Art

[0002] For welding, Figure 1 The bent plates are welded by folding the edges together. The existing traditional manual method is to clamp the edges of two adjacent bent plates with a C-shaped clamp, and multiple people cooperate to assist in the completion. After positioning, they are placed on the ground for manual welding. Since the length of the entire device is as high as 10M, the reliability of single-sided welding is poor, and the entire device needs to be turned over and welded again. In this process, disassembling and assembling the clamp will generate a lot of workload; the reliability of manual welding is poor, it is very dependent on the operator's level, and it is not stable; the labor intensity of turning over is high, and it also has considerable safety hazards.

[0003] In summary, the present application aims to provide an automatic welding platform for the welding of the above-mentioned multiple bent plates, so as to realize automatic welding, reduce labor intensity and avoid safety risks. Summary of the invention

[0004] The invention overcomes the shortcomings of the existing manual welding of multi-folded plates, such as unstable welding quality and high labor intensity, and provides an automatic welding platform, which can realize automatic welding, thereby improving the stability of welding quality and reducing the labor intensity of workers.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: An automatic welding platform is used to weld and connect a plurality of bent plates, wherein the bent plates are provided with folded edges on both sides in the width direction of the bent plates, and the folded edges of adjacent bent plates are fitted together. The platform comprises a platform bracket, a clamping mechanism and a welding mechanism, wherein the clamping mechanism is rotatably connected to the platform bracket, and the welding mechanism is slidably connected to the platform bracket along the length direction of the platform bracket, and a welding device is provided on the welding mechanism that slides along the width direction of the platform bracket, and the clamping mechanism comprises a clamping frame and a plurality of clamping arms slidably connected to the clamping frame, and adjacent clamping arms position the bent plates by fitting the folded edges together.

[0006] In order to solve the need for flipping during double-sided welding, a clamping mechanism that can rotate relative to the platform bracket is provided. The clamping mechanism clamps each bent plate to be welded and makes the folded edges of adjacent bent plates fit together. The welding mechanism slides to weld the gaps formed by each folded edge one by one. The clamping arm positions each bent plate.

[0007] Through the above device, the positioning steps can be simplified, and the rotation and automatic welding of the bent plate can be conveniently realized, thereby saving the time of manual replacement of fixtures, improving welding stability, and reducing the labor intensity and safety risks of turning the bent plate.

[0008] Preferably, the platform bracket is provided with bearing seats at both ends of the clamping frame in the length direction, and transmission shafts extend from both ends of the clamping frame, and the transmission shafts are rotatably connected to the bearing seats, wherein a rotating motor is also provided on the platform bracket, and the transmission motor is connected to a transmission shaft, and the transmission motor can transmit torque to the transmission shaft to drive the clamping frame to rotate. The above features realize the structure in which the clamping mechanism rotates relative to the platform bracket.

[0009] Preferably, the platform bracket is further provided with a positioning device, which includes a positioning cylinder, a positioning slider and a positioning guide rail, the positioning slider is slidably connected to the positioning guide rail, the positioning slider is fixedly connected to the telescopic end of the positioning cylinder, and the positioning slider can be inserted into a positioning position. When in the positioning position, the positioning slider fits the clamping frame to limit the rotation of the clamping frame. The positioning device extends out to limit the clamping frame after the clamping frame rotates into place, thereby limiting the further rotation of the clamping frame.

[0010] Preferably, the platform bracket is provided with welding rails arranged along the length direction on both sides of the clamping frame, and the welding mechanism includes a traveling rail and a welding trolley arranged along the length direction on both sides of the clamping frame on the platform bracket, and the welding trolley is provided with a welding rail arranged along the width direction of the platform bracket, the welding trolley is slidably connected to the traveling rail, and the welding rail is slidably connected to the welding device. The traveling rail enables the welding trolley to reach the gap position to be welded formed by different folding edges. The gap is parallel to the welding rail, and the welding device moves along the welding rail to weld the corresponding gap.

[0011] Preferably, clamping rails are provided along the length direction on both sides of the clamping frame in the width direction, and the clamping arms are slidably connected to the clamping rails. A clamping cylinder is fixedly connected to the clamping frame, and the telescopic end of the clamping cylinder is fixedly connected to the clamping arm. The clamping cylinder pushes the clamping arm to move. Adjacent clamping arms are brought close together to press the folded edges, and the bending plate is positioned by friction.

[0012] Preferably, the length of the travel rail exceeds the length of the clamping frame, and the excess length of the travel rail can accommodate the welding carriage. This feature enables the welding carriage to move outside the clamping frame during the rotation process, thereby avoiding interference with the turning of the clamping frame.

[0013] Preferably, both ends of the travel guide rail exceed the length of the clamping frame and the excess length at both ends can accommodate the welding trolley. This arrangement allows the welding trolley to enter the end after welding and traveling to one end to avoid affecting the flipping of the clamping frame without having to return to the other end, thereby improving the production cycle and production efficiency.

[0014] Preferably, the platform support is further provided with a walkway, which is arranged on both sides of the clamping frame in the width direction. The walkway is convenient for the operator to place the bending plate on the platform and is also convenient for maintenance personnel to inspect and repair.

[0015] Preferably, the clamping arm is provided with a groove on one side that fits the folded edge, and a bite claw is rotatably connected in the groove. The clamping arm is also movably connected to a roller, and the roller includes a roller body and a guide rod connected to both ends of the roller body and coaxial with the roller body. The clamping arm is provided with guide grooves on the side walls on both sides of the groove, and the roller is inserted into the guide grooves. The guide grooves are arranged along the height direction, and the side walls of the roller body are in contact with the folded edge. The rotation paths of the roller and the bite claw interfere with each other. When the roller moves to a rotation point away from the bite claw, the roller pushes the bite claw to rotate around the rotation point and bites the folded edge to enhance the friction force of the clamping arm on the folded edge.

[0016] It can be seen from the above scheme that when the bending plate is clamped by the clamping arm in a U-shape, when the bending plate tends to slide downward, the bending plate and the roller are relatively stationary and move relative to the clamping arm. The roller moves relative to the clamping arm through the guide groove, thereby pushing the engaging claw to rotate, thereby engaging the folded edge and providing greater friction.

[0017] As a preference, the engaging claw is arc-shaped. It can be seen from the above scheme that when the bending plate is placed on the clamping arm in an inverted U shape, the clamping arm approaches the folded edge, and the folded edge first contacts the extended engaging claw. In this process, due to the curved shape of the engaging claw, a vertical force component is provided to the roller to push the roller to reset.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) The bending plate is positioned automatically, and the operator only needs to load and unload the material. This method eliminates the time of disassembling and assembling the fixtures for each folding edge, thus improving production efficiency; (2) A clamping mechanism capable of rotating relative to the platform support is provided, thereby eliminating the need for manual flipping of the turning plate; (3) Through the crane guide rail and welding guide rail, the welding device can reach all places to be welded, realizing automated welding.

[0025] Example: Ginseng Figure 1 and Figure 2 As shown, an automatic welding platform is used to weld and connect a plurality of bent plates 1, wherein the bent plates 1 are provided with folded edges 2 on both sides in the width direction of the bent plates 1. Each of the bent plates 1 fits adjacent folded edges 2 together, and then the bent plates 1 are welded into a whole by double-sided welding.

[0026] Ginseng Figure 3 As shown, the automatic welding platform includes a platform bracket 3, a clamping mechanism 4 and a welding mechanism 5. The clamping mechanism 4 is rotatably connected to the platform bracket 3, and the clamping mechanism 4 includes a clamping frame 6 and a plurality of clamping arms 7 slidably connected in the clamping frame 6. If the platform bracket 3 provides the clamping frame 6 for rotation, the platform bracket 3 needs to provide the clamping frame 6 with sufficient space for rotation. Therefore, the clamping frame 6 is suspended. Since the loading in this application is achieved manually. Therefore, the platform bracket 3 is also provided with a walkway 20, and the walkway 20 is arranged on both sides of the width direction of the clamping frame 6. The walkway 20 is convenient for the operator to place the bent plate 1 on the platform, and is also convenient for maintenance personnel to inspect and repair.

[0027] Ginseng Figure 3 As shown, the platform bracket 3 is provided with bearing seats 8 at both ends of the length direction of the clamping frame 6, and transmission shafts 9 are extended at both ends of the clamping frame 6, and the transmission shaft 9 is rotatably connected to the bearing seats 8, wherein the platform bracket 3 is also provided with a rotating motor 10, and the transmission motor is connected to a transmission shaft 9, and the transmission motor can transmit torque to the transmission shaft 9 to drive the clamping frame 6 to rotate. The above features realize the structure of the clamping mechanism 4 rotating relative to the platform bracket 3. The platform bracket 3 is also provided with a positioning device, which includes a positioning cylinder 11, a positioning slider 12 and a positioning guide rail 13, the positioning slider 12 is slidably connected to the positioning guide rail 13, the positioning slider 12 is fixedly connected to the telescopic end of the positioning cylinder 11, and the positioning slider 12 can be inserted into the positioning position. At the positioning position, the positioning slider 12 fits with the clamping frame 6 to limit the rotation of the clamping frame 6. The platform bracket 3 has positioning devices at both ends of the width direction of the clamping frame 6, and the two positioning devices limit the clamping frame. After the clamping frame 6 rotates to the right position, the positioning device extends out to limit the clamping frame 6, thereby limiting the clamping frame 6 from rotating again.

[0028] Ginseng Figure 6 As shown, the adjacent clamping arms 7 are fitted with the folding edge 2 to position the bent plate 1. The movement of the clamping arms 7 is realized automatically. The clamping guide rails 14 arranged along the length direction are provided on both sides of the clamping frame 6 in the width direction. The clamping arms 7 are slidably connected to the clamping guide rails 14. The clamping frame 6 is fixedly connected with a clamping cylinder 15, and the telescopic end of the clamping cylinder 15 is fixedly connected to the clamping arm 7. The clamping cylinder 15 pushes the clamping arm 7 to move. The adjacent clamping arms 7 are closed together to press the folding edge 2, and the bending plate 1 is positioned by friction.

[0029] Ginseng Figure 5 As shown, it is worth noting that the operator stands on the walkway 20 to unload the material, and the bent plate 1 is placed on each clamping arm 7 with the folded edge 2 facing downward. Each bent plate 1 is also supported by the clamping arm 7. When the clamping frame 6 is turned over and the welding is completed, the clamping arm 7 can be loosened. In this state, the bent plate 1 that has been welded will fall due to gravity. Since the clamping frame 6 is suspended, a support platform that can be raised and lowered can be placed under the clamping frame 6 to receive the fallen bent plate 1 that has been welded. This method further eliminates the need for manual unloading.

[0030] Ginseng Figure 4 As shown, the welding mechanism 5 is slidably connected to the platform bracket 3 along the length direction of the platform bracket 3, and the welding mechanism 5 is provided with a welding device 19 that slides along the width direction of the platform bracket 3. The platform bracket 3 is provided with welding rails 18 arranged along the length direction on both sides of the clamping frame 6. The welding mechanism 5 includes a traveling rail 16 and a welding trolley 17 arranged along the length direction on both sides of the clamping frame 6 on the platform bracket 3. The welding trolley 17 is provided with a welding rail 18 arranged along the width direction of the platform bracket 3. The welding trolley 17 is slidably connected to the traveling rail 16, and the welding rail 18 is slidably connected to the welding device 19. The traveling rail 16 enables the welding trolley 17 to reach the gap position to be welded formed by different folding edges 2. The gap is parallel to the welding rail 18, and the welding device 19 moves along the welding rail 18 to weld the corresponding gap.

[0031] Ginseng Figure 5 As shown, in some embodiments, the length of the travel guide exceeds the length of the clamping frame 6, and the excess length of the travel guide can accommodate the welding trolley 17. This feature enables the welding trolley 17 to move outside the clamping frame 6 when performing the rotation process, thereby avoiding interference with the flipping of the clamping frame 6. Furthermore, both ends of the travel guide exceed the length of the clamping frame 6, and the excess length at both ends can accommodate the welding trolley 17. This setting allows the welding trolley 17 to enter the end after welding and moving to one end to avoid affecting the flipping of the clamping frame 6, without having to return to the other end, thereby improving the production cycle and improving production efficiency.

[0032] In order to solve the requirement of flipping for double-sided welding, a clamping mechanism 4 capable of rotating relative to the platform bracket 3 is provided. The clamping mechanism 4 clamps each bent plate 1 to be welded and makes the folded edges 2 of adjacent bent plates 1 fit each other. The welding mechanism 5 slides to weld the gaps formed by each folded edge 2 one by one. The clamping arm 7 positions each bent plate 1.

[0033] Through the above device, the positioning steps can be simplified, and the rotation and automatic welding of the bending plate 1 can be conveniently realized, thereby saving the time of manual replacement of the clamp, improving the stability of welding, and reducing the labor intensity of turning the bending plate 1 and the resulting safety risks.

[0034] In some embodiments, Figure 7 As shown, the clamping arm 7 is provided with a groove on one side that fits the folded edge 2, and a bite claw 21 is rotatably connected in the groove. The clamping arm 7 is also movably connected with a roller 22, and the roller 22 includes a roller body and a guide rod connected to both ends of the roller body and coaxial with the roller body. The clamping arm is provided with guide grooves 23 on the side walls on both sides of the groove. The guide grooves are arranged along the height direction, and the guide rods are inserted into the guide grooves. The side walls of the roller body are in contact with the folded edge 2, and the rotation paths of the roller 22 and the bite claw 21 interfere with each other. When the roller moves to a rotation point away from the bite claw, the roller pushes the bite claw to rotate around the rotation point and bites the folded edge to strengthen the friction force of the clamping arm on the folded edge.

[0035] Ginseng Figure 8 As shown, when the bending plate 1 is clamped by the clamping arm 7 in a U-shape, when the bending plate 1 has a tendency to slide downward, the bending plate 1 drives the roller 22 to move synchronously through friction, and the roller 22 moves relative to the clamping arm 7 through the guide groove 23, thereby pushing the bite claw to rotate, thereby biting the folded edge and providing greater friction. In some embodiments, the bite claw 21 is arc-shaped. It can be seen from the above scheme that when the bending plate is placed on the clamping arm in an inverted U shape, the clamping arm is close to the folded edge, and the folded edge first contacts the extended bite claw. In this process, due to the curved shape of the bite claw, a vertical component of force is provided to the roller, pushing the roller to reset. Among them, the end of the bite claw 21 away from the roller 22 has a pattern that increases friction.

[0036] The embodiments described above are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
