[0048] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0049] Embodiment 1:

[0050] See also Figure 1 - Figure 6 An industrial robot assisted flipping device includes a basic workbench 1, independent bases 2 are fixedly installed on both sides of the top of the basic workbench 1, the two independent bases 2 are axially symmetrically arranged, a hydraulic cylinder 3 is fixedly installed on one side of the top of each independent base 2, and a load-bearing base 4 is arranged on the other side of the top of the independent base 2. The load-bearing base 4 moves in the horizontal direction of the independent base 2, and the output shaft of the hydraulic cylinder 3 is fixedly connected to the side of the load-bearing base 4 through a connector. A protective component 5 is arranged between the two ends of each independent base 2, and a flipping component 6 is arranged between the two load-bearing bases 4.

[0051] When welding is performed on top of the basic workbench 1, the workpiece to be welded needs to be flipped during the welding process. The load-bearing base 4 and the independent base 2 provide support for the welding workpiece and the flipping assembly 6. When flipping, the protective assembly 5 is used to protect the slag during welding. At the same time, some structures in the flipping assembly 6 can be quickly disassembled to avoid the situation where the entire flipping workbench cannot be used due to slag.

[0052] The protective assembly 5 is composed of a protective plate 501, a support frame 502 and a protective film 503. The protective plate 501 is arranged at one end of the load-bearing base 4, and the protective plate 501 is fixed to the load-bearing base 4 by bolts. The support frame 502 is fixedly welded to the independent base 2. One end of the protective film 503 is connected to the top of the side of the protective plate 501, and the other end of the protective film 503 is connected to the top of the support frame 502. The hydraulic cylinder 3 and the flip assembly 6 are both directly below the protective film 503.

[0053] During protection, the welding workpiece is placed between two protective plates 501. The protective plates 501 can provide positive protection for splashing slag, while the protective plates 501 and the support frame 502 can provide support for the protective film 503 when it is unfolded. The protective film 503 is made of a high-temperature resistant alloy metal film and can protect the hydraulic cylinder 3 and the flip assembly 6.

[0054] The flipping assembly 6 includes two synchronously working flipping control structures, and the flipping control structure includes a stepper motor 601. The stepper motor 601 is fixedly installed on the side of the load-bearing base 4, and the output end of the stepper motor 601 is connected to the connecting sleeve 602 through a coupling transmission. The connecting sleeve 602 is rotatably connected to the load-bearing base 4 through a bearing. One end of the connecting sleeve 602 is snap-connected with a center shaft 603. One end of the center shaft 603 passes through the protective plate 501 and is fixedly installed with a short clip 604. A long clip 605 is installed on the short clip 604, and a number of locking bolts 606 are threadedly connected to the long clip 605.

[0055] Before flipping, the positions of the two load-bearing bases 4 are adjusted by the hydraulic cylinder 3, and the workpiece to be welded is placed between the two long clamps 605 and locked by the locking bolt 606. At this time, the locking bolt 606 or the long clamp 605 is prevented from blocking the welding part, and the contact position of the long clamp 605 and the short clamp 604 is adjustable to ensure that the workpiece is within the welding working range of the welding robot.

[0056] During flipping, the stepper motor 601 works and controls the synchronous rotation of the connecting sleeve 602, the central rotating shaft 603, the short clamping piece 604, and the long clamping piece 605 to realize the flipping of the workpiece to be welded.

[0057] Embodiment 2:

[0058] Based on the above embodiment 1, further description is given.

[0059] See also Figure 1 , Figure 2 Specifically, a plurality of spring buckles 101 are fixedly installed on both sides of the basic workbench 1, and tin foil 102 is laid on the top of the basic workbench 1, and the tin foil 102 is fixed by the spring buckles 101.

[0060] The spring buckle 101 can fix the position of the tin foil 102. The high temperature resistance of the tin foil 102 can be used to prevent welding slag from directly adhering to the basic workbench 1. The tin foil 102 can be separated from the basic workbench 1. When the slag accumulates on the tin foil 102 to a certain extent, it is convenient to centrally remove the slag.

[0061] See also Figure 1 , Figure 3 , Figure 4 Specifically, a through slot 5011 is formed at the bottom end of the protective plate 501 , and the protective plate 501 slides along the extension direction of the independent base 2 through the through slot 5011 .

[0062] By utilizing the structure of the through slot 5011, when the protective plate 501 moves synchronously with the load-bearing base 4, the independent base 2 is prevented from hindering the movement of the protective plate 501. At the same time, the design of the through slot 5011 can increase the protection area of ​​the protective plate 501 and reduce the blind spots of protection.

[0063] Specifically, a protective eaves strip 5012 is fixedly provided on the top of the protective plate 501 , and the protective eaves strip 5012 and the protective plate 501 form an L-shaped structure.

[0064] The protective eaves strips 5012 are used to increase the protective area of ​​the protective plate 501, prevent slag from sliding down between the protective plate 501 and the protective film 503, and reduce the protective blind spots.

[0065] Specifically, a plurality of transverse hooks 5013 are fixedly installed on the top of the side of the protective plate 501. The transverse hooks 5013 are evenly and equidistantly distributed, and the transverse hooks 5013 are directly below the protective eaves strip 5012. The length of the transverse hooks 5013 is less than the length of the protective eaves strip 5012.

[0066] The length of the transverse hook 5013 is controlled to ensure that the transverse hook 5013 and one end of the protective film 503 are completely protected by the protective eaves strip 5012.

[0067] A plurality of vertical hooks 5021 are fixedly mounted on the top of the support frame 502 . The vertical hooks 5021 are evenly and equidistantly distributed, and the height of the vertical hooks 5021 is lower than the height of the horizontal hooks 5013 .

[0068] The protective film 503 is arranged at an angle between the horizontal hook 5013 and the vertical hook 5021 to ensure that the slag does not roll down directly under the protective film 503 .

[0069] A plurality of hanging rings 5031 are fixedly installed at both ends of the protective film 503 . The hanging ring 5031 at one end of the protective film 503 is connected to the corresponding horizontal hook 5013 , and the hanging ring 5031 at the other end of the protective film 503 is connected to the corresponding vertical hook 5021 .

[0070] When the device is used, first use the hanging ring 5031 to hang the protective film 503 between the horizontal hook 5013 and the vertical hook 5021, then adjust the position of the load-bearing base 4 and the protective plate 501 to make the protective film 503 relatively tight, thereby improving the protective effect of the protective film 503.

[0071] Specifically, a through hole is opened on the protective plate 501 , and a movable sleeve 5014 is rotatably connected to the through hole. The central rotating shaft 603 passes through the movable sleeve 5014 and moves to the other end of the protective plate 501 .

[0072] The central shaft 603 and the movable sleeve 5014 are able to rotate freely.

[0073] The movable sleeve 5014 can avoid direct friction between the central shaft 603 and the protection plate 501 , thereby reducing the kinetic energy loss of the stepper motor 601 caused by friction.

[0074] See also Figure 1 , Figure 5 , Figure 6 Specifically, a hexagonal docking groove 6021 is formed at one end of the connecting sleeve 602 away from the stepping motor 601, and a hexagonal docking joint 6031 is fixedly provided at one end of the central rotating shaft 603. The hexagonal docking joint 6031 is inserted into the hexagonal docking groove 6021 after being moved.

[0075] The end position of the hexagonal docking joint 6031 and the inner bottom of the hexagonal docking groove 6021 are both installed with magnetic attraction materials.

[0076] After the central rotating shaft 603 passes through the movable sleeve 5014, the hexagonal docking joint 6031 can be inserted into the hexagonal docking groove 6021, and the hexagonal docking joint 6031 and the hexagonal docking groove 6021 are kept fixed to a certain extent by magnetic attraction, and the movable sleeve 5014 and the protective plate 501 can support the central rotating shaft 603.

[0077] When the central rotating shaft 603 and the short clamp 604 are blocked by materials and cannot be used, the hexagonal docking joint 6031 and the hexagonal docking groove 6021 can be quickly separated to quickly replace the central rotating shaft 603 and the short clamp 604.

[0078] Specifically, two outer alignment holes 6041 are formed on the short clamp 604 , and four inner alignment holes 6051 are formed on the long clamp 605 . The distance between two adjacent inner alignment holes 6051 is equal to the distance between the two outer alignment holes 6041 .

[0079] A through bolt 6042 is inserted between the outer alignment hole 6041 and the inner alignment hole 6051 .

[0080] According to the welding position of the workpiece to be welded, the two inner alignment holes 6051 and the outer alignment holes 6041 are selected to correspond to each other, and are fixed with through bolts 6042 to ensure that the workpiece to be welded is within the working range of the welding robot.

[0081] Working principle:

[0082] When the device is in use, the workpiece to be welded is placed between the two long clamps 605 according to the welding position of the workpiece to be welded, and is fixed with the locking bolt 606. At this time, the long clamp 605 and the locking bolt 606 are prevented from blocking the welding position. Then, the corresponding positions of the two inner alignment holes 6051 and the outer alignment holes 6041 are selected, and fixed with the through bolts 6042 to ensure that the workpiece to be welded is within the working range of the welding robot.

[0083] During welding, the workpiece needs to be flipped. At this time, the stepper motor 601 works and controls the synchronous rotation of the connecting sleeve 602, the central shaft 603, the short clamp 604, and the long clamp 605 to realize the flipping of the workpiece to be welded. At the same time, since the welding workpiece is between the two protective plates 501, the protective plates 501 can provide positive protection for the splashing slag, and the protective plates 501 and the support frame 502 can provide support for the deployment of the protective film 503. The protective film 503 is made of a high-temperature resistant alloy metal film, which can protect the hydraulic cylinder 3 and the flipping assembly 6.

[0084] When the central rotating shaft 603 and the short clamp 604 are blocked by materials and cannot be used, the hexagonal docking joint 6031 and the hexagonal docking groove 6021 can be separated to quickly replace the central rotating shaft 603 and the short clamp 604.

[0085] When the residues accumulate on the tin foil 102 to a certain extent, the tin foil 102 can be separated from the basic workbench 1 to facilitate the centralized removal of the residues.

[0086] In this way, the device can flip the workpiece and realize self-protection of the device during the welding process.

[0087] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
