Description

Technical Field

[0001] The present invention relates to the technical field of welding equipment, and more particularly to an automatic positioning welding equipment for producing furniture metal splicing parts. Background Art

[0002] Metal parts are an indispensable component in modern furniture manufacturing. They not only provide structural stability but also enhance functionality. In the furniture manufacturing industry, the welding quality of metal parts (such as connectors, brackets, hinges, etc.) directly affects the strength, precision and aesthetics of furniture.

[0003] In the production of furniture metal splices, the choice of welding method directly affects efficiency, cost and product quality. Among them, laser welding, as a representative of modern precision welding technology, has shown significant advantages in the manufacturing of furniture metal splices.

[0004] However, existing automatic positioning welding equipment has the following problems when using laser welding to weld furniture metal parts:

[0005] 1. When welding the bottom of a metal splice after the top is welded, the splice needs to be disassembled and re-clamped, which makes it inconvenient to turn it over quickly, affecting the overall welding efficiency of the splice; 2. During the welding process of furniture metal splices, improper clamping may cause damage, deformation or loosening of the parts, and loosening may affect the welding accuracy of the parts. Summary of the Invention

[0006] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides an automatic positioning welding device for producing furniture metal splicing parts to solve the technical problems raised in the background art.

The second fixed plate 103 is fixedly connected to one side of the top of the mounting plate 101.

[0040] Among them, the mounting plate 101 is fixedly connected to the fourth fixed plate 105 on both sides away from the first fixed plate 102, and the transmission gear assembly 15 is movably connected to the adjacent side of the fourth fixed plate 105 and near the top position. The surface of the transmission gear assembly 15 is fixedly connected with gears located at the top of the clamping screw 13 and the top of the clamping rotating gear group 11 respectively. The surface of the clamping rotating gear group 11 and the gear position located on the surface of the transmission gear assembly 15 are movably sleeved with a movable screw sleeve 14. The gears on the surface of the transmission gear assembly 15 are respectively meshed with the clamping screw 13 and the movable screw sleeve 14.

[0043] The working principle of the present invention is as follows: first, when the splicing pieces are clamped and welded, the welded splicing pieces are placed at an adjacent side position of the multi-structure clamping head 10, and then the servo motor 801 on the right side of the first fixed plate 102 is turned on, so that the servo motor 801 drives the clamping transmission shaft 12 and the clamping screw 13 fixedly connected thereto to rotate under the support of the second fixed plate 103 and the fifth fixed plate 106, and then the rotation of the clamping screw 13 drives the transmission gear assembly 15 to rotate, and then the transmission gear assembly 15 rotates so that the gear on its surface drives the moving screw sleeve 14 on the surface of the clamping rotating gear set 11, and at this time the moving screw sleeve 14 slides on the surface of the clamping rotating gear set 11, and then the sliding of the moving screw sleeve 14 drives the clamping gear set 16, and at this time the clamping gear set 16 rotates after being restricted by the rotation limit box 9, and then the clamping gear set 16 selects the multi-structure clamp on its surface. Driven by the holding head 10, the multi-structure clamping heads 10 are close to each other to clamp the splicing pieces. At this time, the telescopic clamping head 1704 is squeezed by the clamped splicing piece, and then the telescopic clamping head 1704 pushes the rubber sealing plug 1705 to squeeze the air inside the air pressure chamber 1706. At this time, the air in the air pressure chamber 1706 enters the interior of the air collecting chamber 1702 through the connecting hole 1707, and then the air inside the air collecting chamber 1702 enters the interior of the remaining cylindrical air pipes 1703 through the connecting hole 1707, and pushes the telescopic clamping head 1704 with smaller squeezing force to fix the splicing piece. At the same time, due to the limitation of the material of the telescopic clamping head 1704 itself, the surface of the splicing piece is protected to avoid damage caused by clamping. Then, through the flexible change of characteristics of the telescopic clamping head 1704 on one side of the rectangular air chamber 1701, various special-shaped splicing pieces can be clamped and fixed through the multi-structure clamping head 10 and the adjusting clamp assembly 17;

[0044] Then, after the intelligent positioning welding component 6 is positioned by the welding slider 5, the positioning frame 4 and the electric sliding component 3 to weld the splicing parts, the servo motor 801 on the left side of the first fixed plate 102 is turned on, so that the transmission main gear group 802 rotates and drives the clamping rotating gear group 11 to rotate, and then the clamping rotating gear group 11 rotates so that the clamping rotating gear group 11 drives the rotating limit box 9 to rotate on the surface of the fifth fixed plate 106. At this time, the moving screw sleeve 14 is restricted by the transmission gear assembly 15 and does not follow the rotation of the clamping rotating gear group 11. Then the rotation of the rotating limit box 9 drives the clamping gear group 16 inside it and the splicing parts clamped by the multi-structure clamping head 10 to rotate together. At this time, the intelligent positioning welding component 6, the positioning frame 4 and the electric sliding component 3 are started to weld the rotated splicing parts.

[0045] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
