Technical Field
[0001] This invention relates to the field of welding technology, specifically to an automatic flipping and positioning device for laser welding of high-voltage power fittings. Background Technology
[0002] High-voltage power fittings are the core connecting components of power transmission lines. The quality of their laser welding directly determines the stability and safety of the line operation. At present, fitting welding processing generally adopts fixed tooling or simple flip-over fixtures to complete the clamping operation.
[0003] Existing equipment lacks a gripper-linked conveyor and release structure adapted to conveyor belts. During the conveyor belt transport and workstation release and storage process, the lack of limiting and fixing constraints makes the workpiece prone to displacement and misalignment, resulting in poor workpiece positioning accuracy and inability to accurately connect to the welding station. At the same time, traditional fixtures cannot achieve stable flipping under the clamping state, and most require release and reset, secondary positioning and welding, which is prone to positioning deviation, causing uneven welds and coaxiality deviations. To address this, the present invention provides an automatic flipping and positioning device for laser welding of high-voltage power fittings. Summary of the Invention
[0004] The purpose of this invention is to provide an automatic flipping and positioning device for laser welding of high-voltage power fittings, so as to solve the problems mentioned in the background art.
[0005] The technical solution of this invention is: an automatic flipping and positioning device for laser welding of high-voltage power fittings, comprising a welding base, a mounting side box, and a storage base. A movable guide plate is fixedly connected between the welding base and the mounting side box. A movable cylinder is fixedly connected to the top of the movable guide plate. A connecting plate is fixedly connected to the output end of the movable cylinder. A clamping arm is fixedly connected to one side of the connecting plate. A fixed column is fixedly connected to the bottom of the clamping arm. A fixed guide column is fixedly connected to the inner side of the fixed column. Limiting outer plates are fixedly connected to both ends of the fixed guide column. Two clamping claws are slidably engaged on the outer side of the fixed guide column. A clamping cylinder is fixedly connected to the inner side of the clamping arm. A fixed plate is fixedly connected to the inner side of the clamping arm. The output end of the clamping cylinder passes through the fixed plate, and a connecting clamping block is fixedly connected to the output end of the clamping cylinder. A rotating plate is rotatably connected to the top of the connecting clamping block and the clamping claws. A flipping roller is rotatably connected to the inner side of the clamping claws. A flipping clamping plate is fixedly connected to one end of the flipping roller. A flipping slide bar is slidably engaged on the inner side of the clamping claws. A toothed rack is installed on one side of the flipping slide bar, and a toothed ring is provided on the outer side of the flipping roller. The toothed rack and the toothed ring mesh with each other. A flipping slider is fixedly connected to the top of the flipping slide bar, and a rotating wheel is rotatably connected to the inner side of the flipping slider. A flipping cylinder is fixedly connected to one side of the clamping arm, and a flipping mounting plate is fixedly connected to the output end of the flipping cylinder. A flipping groove plate is fixedly connected to one side of the flipping mounting plate, and the flipping slider slides and engages with the inner side of the flipping groove plate. In use: the clamping cylinder controls the pulling of the connecting clamping block to move up and down, and the clamping claws are limited by the fixed guide post. The connecting clamping block pulls the rotating plate to rotate, so that the two clamping claws come closer to each other. The flipping clamping plate clamps both sides of the object. The flipping cylinder controls the flipping mounting plate to move up and down, pulls the flipping groove plate to move up and down, and pulls the flipping slider to move up and down. When the clamping claws move, the flipping slider slides inside the flipping groove plate. When the flipping slide bar moves up and down, the toothed rack and the toothed ring can rotate the flipping roller, so that the flipping clamping plate can rotate, and the object is flipped, which facilitates welding.
[0006] Preferably, a fixed outer frame is slidably engaged with the inner side of the storage base. A push spring is installed at the bottom of the fixed outer frame. Guide inclined blocks are fixedly connected to both sides of the fixed outer frame. The bottom of the clamping claw is inclined. Inner sliding columns are slidably engaged with both sides of the storage base. A return spring is fixedly connected to one end of each inner sliding column. A limit connecting plate is fixedly connected to the end of the inner sliding column away from the return spring. A slanted rotating pressure column is fixedly connected to one side of the limit connecting plate. A placement base plate is fixedly connected to the top of the storage base. A torsion column is fixedly connected to the inner side of the placement base plate. A torsion cylinder is rotatably connected to the outer side of the torsion column. A torsion spring is installed between the torsion cylinder and the torsion column. A fixed rotating plate is fixedly connected to the outer side of the torsion cylinder. A fixed clamping block is fixedly connected to one side of the fixed rotating plate. A welding robotic arm is fixedly connected to the inner side of the welding base. A laser welding head is installed at the output end of the welding robotic arm. In use: an object is placed inside the storage base, and the object is secured by a fixed... The clamping blocks hold the fixed object on both sides, the inclined rotating pressure columns clamp the fixed outer frame on both sides, the guide inclined blocks are inside the inclined rotating pressure columns, and the storage base is placed on top of the conveying device for conveying. The moving cylinder controls the movement of the clamping claws. When it moves to both sides of the fixed outer frame, it pushes one end of the inclined rotating pressure column to separate the inclined rotating pressure column from the outside of the fixed outer frame. When the connecting plate clamps, the bottom inclined surface of the connecting plate pushes the guide inclined block downward, pushing the fixed outer frame downward, so that the fixed rotating plate separates from the inner wall of the fixed outer frame. The torsion cylinder is twisted to both sides by the torsion spring to release the object, so that the flipping clamping plate clamps the object. When moving horizontally, the fixed outer frame is always retracted inside the storage base. After moving a certain distance, the inclined rotating pressure column is pulled by the return spring to press the inclined rotating pressure column on the top of the fixed outer frame, so that the fixed rotating plate is always unfolded. After welding is completed, the reverse process can be used to place the welded object on top of the placement base plate. The fixed outer frame is reset to allow the fixed clamping blocks to clamp.
[0007] This invention provides an improved automatic flipping and positioning device for laser welding of high-voltage power fittings, which has the following improvements and advantages compared with the prior art: Firstly, the automatic flipping and positioning device for laser welding of high-voltage power fittings described in this invention uses a clamping cylinder to control the pulling of the connecting clamping block to move up and down. The clamping claws are limited by a fixed guide post. The connecting clamping block pulls the rotating plate to rotate, so that the two clamping claws come closer to each other. The flipping clamping plate clamps both sides of the object. The flipping cylinder controls the flipping mounting plate to move up and down, pulling the flipping groove plate to move up and down, and pulling the flipping slider to move up and down. When the clamping claws move, the flipping slider slides inside the flipping groove plate. When the flipping slider moves up and down, the toothed row and toothed ring can make the flipping roller rotate, so that the flipping clamping plate rotates, carrying the object to flip, which facilitates welding. Secondly: The automatic flipping and positioning device for laser welding of high-voltage power fittings described in this invention includes a storage base containing an object. The object is held in place by two fixed clamping blocks. An inclined rotating pressure column is clamped on both sides of a fixed outer frame. A guide inclined block is located inside the inclined rotating pressure column. The storage base is placed on top of a conveying device for transport. A moving cylinder controls the movement of the clamping claws. When the claws move to both sides of the fixed outer frame, pushing one end of the inclined rotating pressure column separates it from the outside of the fixed outer frame. When the connecting plate clamps the object, the bottom inclined surface of the connecting plate pushes the guide inclined block towards... Push the fixed outer frame downwards to separate the fixed rotating plate from the inner wall of the fixed outer frame. The torsion cylinder is twisted to both sides by the torsion spring to release the object. The flip clamping plate clamps the object and moves horizontally. The fixed outer frame is always retracted inside the storage base. After moving a certain distance, the inclined rotating pressure column is pulled by the return spring to press the inclined rotating pressure column on the top of the fixed outer frame, so that the fixed rotating plate is always unfolded. After welding is completed, the welding completed object can be placed on the top of the placement base plate by reversing the process. The fixed clamping block clamps the object by resetting the fixed outer frame. In summary, the automatic flipping and positioning device for laser welding of high-voltage power fittings described in this invention features a gripper linkage conveyor structure adapted to a conveyor belt. This structure provides stable limiting constraints during workpiece transportation and storage, preventing workpiece offset and misalignment, improving workpiece positioning accuracy, and ensuring precise docking of the workpiece with the welding station. Furthermore, it can achieve stable automatic flipping while the workpiece is clamped, eliminating the need for clamping, resetting, and secondary positioning to complete multi-sided welding. This avoids deviations caused by secondary positioning and solves problems of uneven weld seams and excessive coaxiality, effectively improving the processing accuracy and efficiency of laser welding of high-voltage power fittings.

The clamping claws 17 are limited by the fixed guide post 15. The connecting clamping block 12 pulls the rotating plate 13 to rotate, so that the two clamping claws 17 move closer to each other. The flipping clamping plate 25 clamps both sides of the object. The flipping cylinder 18 controls the flipping mounting plate 19 to move up and down, pulls the flipping groove plate 20 to move up and down, and pulls the flipping slider 22 to move up and down.

When the connecting plate 7 clamps, the bottom inclined surface of the connecting plate 7 pushes the guide inclined block 31 downward, pushing the fixed outer frame 26 downward, so that the fixed rotating plate 37 separates from the inner wall of the fixed outer frame 26. The torsion cylinder 36 is twisted to both sides by the torsion spring 35 to release the object, so that the flip clamping plate 25 clamps the object. When moving horizontally, the fixed outer frame 26 is always retracted inside the storage base 9.
