DETAILED DESCRIPTION

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0035] In the description of the present invention, it should be understood that the terms "up", "down", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0036] A welding clamping device of the present invention, such as Figures 1 to 3 As shown, it includes a main structure 5, a clamping device and a welding device, wherein the welding device includes a welding gun clamp seat main frame 19 slidably mounted on the main structure 5 and welding gun clamp seats 21 symmetrically mounted on both sides of the welding gun clamp seat main frame 19, and the welding gun clamp seat 21 is mounted with a welding gun 1;

[0037] The clamping device includes a front clamping rod support and a rear clamping rod support mounted on the lower side of the main structure 5, the front clamping rod support is mounted with a front clamping rod 13, the top of the front clamping rod 13 is mounted on the top of the front clamping rod support through a first screw rod 11 and a front clamping rod tensioning spring 12, and the middle part is fixed to the bottom of the front clamping rod support through a front clamping rod support shaft 28;

[0038] The rear clamping rod support is installed with a rear clamping rod 14, the top of the rear clamping rod 14 is connected to the small connecting rod 22, and the middle part is fixed to the bottom of the rear clamping rod support through the rear clamping rod support shaft 29;

[0039] It also includes a rear clamping rod tensioning threaded rod 15, which is installed on the rear bottom of the welding gun clamp main frame 19 through a pre-tightening nut 17 and a rear clamping rod tensioning spring 16, and the small connecting rod 22 is connected to the rear clamping rod tensioning threaded rod 15;

[0040] The clamping device also includes a clamping sliding assembly, which is slidably installed on the lower side of the main structure 5. The welding gun clamp main frame 19 can push the clamping sliding assembly to slide toward the top of the front clamp rod 13, so that the clamping sliding assembly touches the top of the front clamp rod 13.

[0041] At present, the extraction, positioning and welding of the anchor hook sleeve 31 are all manual operations. Workers cannot weld on both sides at the same time, resulting in low work efficiency, low positioning accuracy, and unreliable quality. In addition, the anchor hook sleeve 31 is short in size, and manual welding poses a safety hazard. To solve the above problems, the present application provides a welding clamping device, which integrates the welding device and the clamping device into one, thereby achieving simultaneous clamping and welding of the anchor hook sleeve 31.

[0042] Specifically, such as Figures 4 to 7As shown, welding gun clamp seats 21 are provided on both sides of the welding gun clamp main frame 19. The welding gun clamp seats 21 are used to fix the welding gun 1 to achieve bilateral synchronous welding. The clamping device includes a front clamping rod 13 and a rear clamping rod 14. The front clamping rod 13 is mounted on the front clamping rod support 26, and the rear clamping rod 14 is mounted on the rear clamping rod support 27. The front clamping rod 13 and the rear clamping rod 14 are staggered with the welding gun 1 on both sides to prevent the front clamping rod 13 and the rear clamping rod 14 from affecting the welding. The top of the front clamp rod 13 is installed on the top of the front clamp rod support 26 through the first screw rod 11 and the front clamp rod tensioning spring 12. The first screw rod 11 and the front clamp rod tensioning spring 12 keep the front clamp rod 13 in a tensioned state, that is, the clamping device is in a loose state. The middle part of the front clamp rod 13 is fixed to the bottom of the front clamp rod support 26 through the front clamp rod support shaft 28, and the front clamp rod 13 can rotate around the front clamp rod support shaft 28. When the lower part of the front clamp rod 13 rotates toward the welding gun clamp main frame 19, the front clamp rod 13 is in a clamped state.

[0043] The top of the rear clamping rod 14 is connected to the small connecting rod 22, and the small connecting rod 22 is connected to the rear clamping rod tensioning threaded rod 15. The rear clamping rod tensioning threaded rod 15 is fixed to the rear bottom of the welding gun clamp main frame 19. The rear clamping rod tensioning threaded rod 15 is installed with a pre-tightening nut 17 and a rear clamping rod tensioning spring 16. The middle part of the rear clamping rod 14 is fixed to the rear clamping rod support 27 through the rear clamping rod support shaft 29, and the rear clamping rod 14 can rotate around the rear clamping rod support shaft 29;

[0044] The welding gun clamp seat main frame 19 can slide along the frame of the main structure 5. In this embodiment, when the welding gun clamp seat main frame 19 slides to the right, it drives the rear clamp rod tensioning threaded rod 15 to slide to the right together, and the rear clamp rod tensioning threaded rod 15 applies a rightward pulling force to the top of the rear clamp rod 14. Since the middle part of the rear clamp rod 14 is fixed to the rear clamp rod support 27 through the rear clamp rod support shaft 29, the upper part of the rear clamp rod 14 moves to the right and the lower part moves to the left, so that the lower part of the rear clamp rod 14 is clamped toward the front clamp rod 13.

[0045] The welding gun clamp seat main frame 19 slides to the right, which pushes the clamping sliding assembly to slide toward the top of the front clamping rod 13, so that the clamping sliding assembly touches the top of the front clamping rod 13, and pushes the upper part of the front clamping rod 13 to the left, so that the front clamping rod 13 rotates around the front clamping rod support shaft 28, and its lower part is clamped toward the direction of the rear clamping rod 14, finally achieving the clamping of the front clamping rod 13 and the rear clamping rod 14;

[0046] When the welding gun clamp main frame 19 slides to the left, the rear clamp rod 14 is restored from the clamped state to the loosened state, and its operation is opposite to that when clamped, and the sliding assembly will leave the front clamp rod 13, so that the front clamp rod 13 is restored to the tensioned state, that is, the loosened state, thereby realizing the loosening action of the front clamp rod 13 and the rear clamp rod 14.

[0047] Preferably, the clamping sliding assembly includes a clamping sliding push rod 25 and a reverse connecting rod 18, wherein the clamping sliding push rod 25 is slidably connected to the main structure 5 through a guide seat 24, and the middle portion of the reverse connecting rod 18 is mounted on a fixed seat at the lower end of the main structure 5 through a rotating shaft 30;

[0048] The tail end of the clamping sliding push rod 25 is connected to the top of the reverse connecting rod 18;

[0049] The clamping sliding push rod 25 is equipped with a clamping sliding push rod tensioning spring 23;

[0050] When the welding gun clamp seat main frame 19 slides toward the reverse connecting rod 18 , it pushes the reverse connecting rod 18 to rotate around the rotating shaft 30 , and the rotation direction is consistent with the sliding direction of the welding gun clamp seat main frame 19 .

[0051] Specifically, when the welding gun clamp seat main frame 19 slides to the right, it pushes the lower part of the reverse connecting rod 18 to move to the right, and the reverse connecting rod 18 rotates around the rotating shaft 30 due to the driving force, so that the upper part thereof moves to the left, exerting a leftward thrust on the clamping sliding push rod 25, so that the clamping sliding push rod 25 moves to the left, so that its front end touches the front clamping rod 13, so that the upper part of the front clamping rod 13 moves to the left, thereby causing the front clamping rod 13 to rotate around the front clamping rod support shaft 28, so that its lower part rotates toward the direction of the rear clamping rod 14, that is, the clamping state of the front clamping rod 13 is achieved;

[0052] When the welding gun clamp main frame 19 leaves the reverse connecting rod 18, the lower part of the reverse connecting rod 18 loses its thrust and no longer applies a leftward thrust to the clamping sliding push rod 25. The clamping sliding push rod 25 then moves to the right under the reaction force of the clamping sliding push rod tensioning spring 23 and returns to its original position. At this time, the upper part of the front side clamping rod 13 is no longer subjected to a leftward thrust, and under the reaction force of the front side clamping rod tensioning spring 12, it recovers from a clamped state to a loosened state.

[0053] Preferably, bearing holes are provided on both sides of the middle frame of the main structure 5, bearings 6 are installed in the bearing holes, a transmission screw 8 is provided between the bearings 6, and a transmission gear 9 is installed at the front end of the transmission screw 8;

[0055] The main structure 5 is also equipped with a guide rail 10, and the welding gun holder main frame 19 is provided with a guide rail 10 groove, and the guide rail 10 groove is connected to the guide rail 10;

[0056] The welding gun holder main frame 19 is connected to the transmission screw 8 through a threaded guide seat 20;

[0057] The motor 7 drives the transmission screw 8 to rotate, and the transmission screw 8 drives the welding gun clamp main frame 19 to slide along the guide rail 10.

[0058] The motor 7 rotates, and through its pinion meshing with the transmission gear 9, it drives the transmission screw 8 to rotate. The rotation of the transmission screw 8 drives the welding gun clamp main frame 19 to slide along the guide rail 10, thereby achieving the effect of the welding gun clamp main frame 19 sliding along the main structure 5.

[0059] Preferably, the front clamping rod 13 rotates around the front clamping rod support shaft 28 , and its rotation direction is consistent with the sliding direction of the welding gun clamp main frame 19 .

[0060] Preferably, the rear clamping rod 14 rotates around the rear clamping rod support shaft 29 , and its rotation direction is opposite to the sliding direction of the welding gun clamp main frame 19 .

[0061] Preferably, the welding gun 1 is fixed to the welding gun clamp seat 21 by a clamping bolt 3, and a rubber pad 2 is provided at the fixing position.

[0062] Preferably, a manipulator mounting seat 4 is provided on the top of the main structure 5 , and the main structure 5 is connected to the manipulator via the manipulator mounting seat 4 .

[0063] The working principle of this embodiment is as follows:

[0064] like Figures 4 to 7 As shown, Figures 4 to 7For a clamping welding process, first, the manipulator is connected to the device through the manipulator mounting seat 4, and the device is dragged to the designated anchor hook sleeve 31 and the material picking seat 32 position, and the motor 7 is started to make the welding gun clamp seat main frame 19 start to move to the right. At this time, the front clamping rod 13 and the rear clamping rod 14 clamp inward until the two ends of the anchor hook sleeve 31 are clamped, and the motor 7 stops working. The welding gun clamp seat main frame 19 has moved to the starting position of welding at this time, and then the manipulator drags and clamps the device to the designated anchor hook sleeve 31 welding position. At this time, the two The side welding gun 1 starts and begins to weld the anchor hook sleeve 31. At the same time, the motor 7 starts, the welding gun clamp main frame 19 starts to move to the left, and the front clamp rod 13 and the rear clamp rod 14 start to open outward, until the welding gun clamp main frame 19 completes the welding of the anchor hook sleeve 31 with the welding gun 1. The welding gun 1 stops working, the motor 7 stops working, and finally the manipulator drags the anchor hook sleeve 31 automatic welding machine to clamp the mobile positioning welding device and return to the designated anchor hook sleeve 31 material picking seat 32 position again to prepare for the next operation. This process ends.
