Description

Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to an automatic flipping welding robot. Background Technique

[0002] A welding robot is an industrial robot specialized in welding, including cutting and spraying, and it has a wide range of applications in industries such as automobile manufacturing, machinery manufacturing, aerospace, shipbuilding, and construction fields.

[0003] When the existing welding robot flips, it uses a control system to control the operation of two motors, and the motors respectively control the flipping of two workpieces. The two motors operate independently, which not only increases the operating cost, but also may cause errors during the operation of the two motors, resulting in different flipping angles of the two workpieces, thus causing the welding points to misalign and affecting the product quality.

[0004] To solve the above problems, an automatic flipping welding robot is proposed in this application. Summary of the Invention

[0005] To solve the above technical problems, the utility model provides an automatic flipping welding robot, which includes a welding table. A support column and a welding arm are fixedly arranged on the welding table. A welding groove, a first chute, and a second chute are opened on the welding table. A limiting plate and a rack are arranged in the first chute. A connecting plate is fixedly arranged on the rack. A gear is meshed with the rack. A hydraulic cylinder is fixedly arranged on the connecting plate. An electric telescopic rod is fixedly arranged on the gear. A fixed clamp is fixedly arranged on the electric telescopic rod.

[0006] Preferably, a guiding plate is fixedly arranged below the welding table. Anti-falling plates are fixedly arranged on both sides of the guiding plate. The guiding plate is in an inclined state.

[0007] Preferably, the limiting plate is fixedly connected to one end of the first chute. The rack is slidably connected in the first chute. The connecting plate is fixedly connected to the bottoms of the racks on both sides. The telescopic end of the hydraulic cylinder is fixedly connected to the connecting plate. The hydraulic cylinder is fixedly installed at the bottom of the welding table.

[0008] Preferably, the second chute is opened in the first chute. The length of the second chute is equal to half of the length of the first chute. The length of the rack is equal to half of the length of the first chute. The gear is meshed with the rack. The gear is rotatably connected to the welding table. The fixed end of the electric telescopic rod is fixedly connected to the gear. The fixed clamp is fixedly connected to the telescopic end of the electric telescopic rod.

[0009] Preferably, the rack is slidably connected in the first chute, the connecting plate is slidably connected to the lower surface of the welding table, the connecting part between the rack and the connecting plate is slidably connected in the second chute, the width of the rack is equal to the width of the first chute, and the width of the second chute is smaller than the width of the first chute.

[0010] Preferably, the guide plate is fixedly connected to the side of the welding groove, and the width of the guide plate is equal to the width of the welding groove.

[0011] The above technical solution of the present utility model has the following beneficial technical effects:

[0012] A hydraulic cylinder is arranged at the bottom of the welding table of the present utility model. The telescopic movement of the hydraulic cylinder is used to push or pull back the connecting plate. The connecting plate connects the racks on both sides into one body. When the connecting plate moves, the two racks will also move simultaneously. Through the design of the two chutes, the movement of the rack and the connecting plate is more stable. During the movement of the rack, the upper gear will rotate accordingly, driving the telescopic rod and the clamping hand in the welding groove to rotate, and then driving the workpieces to be welded on both sides to rotate simultaneously, avoiding the error generated when two motors are controlled separately, resulting in the welding points not aligning, improving the product quality. Using one hydraulic cylinder instead of two motors to work reduces the operating cost. At the same time, a guide plate is arranged on the side of the welding groove to block the side of the welding groove, preventing the sparks generated during welding from splashing out. The lower guide plate can also guide the welded workpieces to the cooling area, avoiding the situation that the welded workpieces cannot be taken off in time by the staff due to high temperature, so that the high-temperature workpieces can be cooled in time.

[0020] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present utility model.

[0021] The following describes an automatic flipping welding robot provided by some embodiments of the present utility model with reference to the accompanying drawings. Embodiment

[0022] As shown in Figures 1-4 the accompanying drawings, an automatic flipping welding robot provided by the present utility model includes a welding table 1, on which a support column 101 and a welding arm 2 are fixedly arranged. A welding groove 102, a first chute 103, and a second chute 104 are formed on the welding table 1. A limiting plate 3 and a rack 4 are arranged in the first chute 103. A connecting plate 401 is fixedly arranged on the rack 4. A gear 5 meshes with the rack 4. A hydraulic cylinder 7 is fixedly arranged on the connecting plate 401. An electric telescopic rod 6 is fixedly arranged on the gear 5. A fixed clamp 601 is fixedly arranged on the electric telescopic rod 6. A guide plate 8 is fixedly arranged below the welding table 1. Anti-falling plates 801 are fixedly arranged on both sides of the guide plate 8. The guide plate 8 is in an inclined state. The limiting plate 3 is fixedly connected to one end of the first chute 103. The rack 4 is slidably connected in the first chute 103. The connecting plate 401 is fixedly connected to the bottoms of the two racks 4. The telescopic end of the hydraulic cylinder 7 is fixedly connected to the connecting plate 401. The hydraulic cylinder 7 is fixedly installed at the bottom of the welding table 1. The second chute 104 is formed in the first chute 103. The length of the second chute 104 is equal to half of the length of the first chute 103. The length of the rack 4 is equal to half of the length of the first chute 103. The gear 5 meshes with the rack 4. The gear 5 is rotatably connected to the welding table 1. The fixed end of the electric telescopic rod 6 is fixedly connected to the gear 5. The fixed clamp 601 is fixedly connected to the telescopic end of the electric telescopic rod 6. The rack 4 is slidably connected in the first chute 103. The connecting plate 401 is slidably connected to the lower surface of the welding table 1. The connecting part between the rack 4 and the connecting plate 401 is slidably connected in the second chute 104. The width of the rack 4 is equal to the width of the first chute 103. The width of the second chute 104 is smaller than the width of the first chute 103. The guide plate 8 is fixedly connected to the side of the welding groove 102. The width of the guide plate 8 is equal to the width of the welding groove 102.

[0023] Specifically, four support columns 101 are fixedly welded to the bottom of the welding table 1 to provide support for the welding table 1. A welding arm 2 is fixedly installed on the upper surface of the welding table 1 so that the welding arm 2 can perform welding operations on the workpieces on the welding table 1. A welding groove 102 is formed in the welding table 1. Two electric telescopic rods 6 are rotatably connected to the side plates of the welding groove 102. A fixed clamp 601 is fixedly installed at the telescopic end of the electric telescopic rod 6 so that the two fixed clamps 601 can fix the two workpieces to be welded. The electric telescopic rod 6 can control the two workpieces to move away from or close to each other through telescoping. The fixed end of the electric telescopic rod 6 is fixedly connected to a gear 5, and the part between the gear 5 and the electric telescopic rod 6 is rotatably connected to the side plate of the welding groove 102. A rack 4 is engaged below each of the two gears 5. The two racks 4 are slidably connected in the second chute 104 so that when the rack 4 slides in the first chute 103, it can drive the gear 5 to rotate, thereby controlling the rotation of the electric telescopic rod 6 and the fixed clamp 601, and then realizing the flipping of the workpiece. The two racks 4 are connected together by a bottom connecting plate 401. A second chute 104 is formed in the first chute 103 so that the connecting part between the rack 4 and the connecting plate 401 can slide in the second chute 104, so that the rack 4 slides in the first chute 103 and the connecting plate 401 slides at the bottom of the welding table 1. The width of the rack 4 is equal to the width of the first chute 103, and the width of the first chute 103 is greater than the width of the second chute 104, so that the rack 4 will not enter the second chute 104 and always slides in the first chute 103, making the sliding of the rack 4 and the connecting plate 401 more stable. A limit plate 3 is fixedly welded to one end of the first chute 103 so that the rack 4 will be blocked by the limit plate 3 after moving a certain distance, thus preventing the rack 4 from disengaging from the gear 5. A hydraulic cylinder 7 is fixedly welded to the connecting plate 401, and the fixed end of the hydraulic cylinder 7 is fixedly installed at the bottom of the welding table 1 so that the hydraulic cylinder 7 can control the movement of the connecting plate 401, thereby driving the two racks 4 on both sides to move simultaneously, and then driving the gear 5, the electric telescopic rod 6, and the fixed clamp 601 to rotate simultaneously, realizing the automatic flipping of the two workpieces. When the welding is completed, the fixed clamp 601 can directly put down the workpiece, and the workpiece directly falls onto the guiding plate 8 below. Since the guiding plate 8 is in an inclined state and anti-falling plates 801 are fixedly welded on both sides of the guiding plate 8, the workpiece can slide along the guiding plate 8 to the end of the guiding plate 8. A cooling area can be set at the end of the guiding plate 8, which can prevent the staff from accidentally touching the high-temperature workpiece and reduce the time for waiting to pick up the workpiece after cooling.

[0024] Working principle and usage process of the utility model: First, fix the two workpieces to be welded on the fixing clamps 601 on both sides respectively. Move the two workpieces closer by the telescopic movement of the electric telescopic rod 6. Then start the welding arm 2 to weld the welding points. After one side is welded, start the hydraulic cylinder 7 and control the telescopic end to extend or retract. The hydraulic cylinder 7 will push or pull the connecting plate 401 to slide at the bottom of the welding table 1. At the same time, the racks 4 on both sides will also drive and slide in the first chute 103 respectively. After sliding a certain distance, the gears 5 engaged with the racks 4 will rotate 180 degrees, thereby driving the two electric telescopic rods 6 and the fixing clamps 601 to rotate, and further enabling the two workpieces to be flipped simultaneously, so as not to affect the welding points on the other side. Then control the welding arm 2 to weld the welding points on the other side. After both sides are welded, control the fixing clamps 601 to release the workpieces, so that the workpieces directly fall onto the guiding plate 8 below, and finally slide into the cooling area to complete the collection.

[0025] It should be understood that the above specific embodiments of the utility model are only used for exemplary illustration or explanation of the principle of the utility model, and do not constitute a limitation to the utility model. Therefore, any modifications, equivalent replacements, improvements, etc. made without departing from the spirit and scope of the utility model shall be included within the protection scope of the utility model.
