Description

Technical Field

[0001] The present invention relates to the technical field of laser welding of aluminum profiles, and more particularly to a laser welding machine for automatically butt - jointed aluminum profile processing. Background Art

[0002] Aluminum profiles are aluminum materials obtained by melting, extruding aluminum rods to get aluminum materials with different cross - sectional shapes. The production process of aluminum profiles mainly includes three processes: melting and casting, extrusion, and coloring. Among them, coloring mainly includes processes such as oxidation, electrophoretic coating, fluorocarbon spraying, powder spraying, and wood grain transfer. Aluminum profiles are aluminum materials obtained by melting, extruding aluminum rods to get aluminum materials with different cross - sectional shapes.

[0003] Currently, when aluminum profiles are welded into an aluminum frame, first, workers cut the whole aluminum profile into the required lengths. Then, they move the aluminum profiles to the fixture bed. At this time, the fixtures on the fixture bed can clamp and fix the aluminum profiles. While clamping, the aluminum profiles are also butt - jointed in pairs for later welding. When the aluminum profiles are spliced and fixed, the worker holds a welding torch and starts to weld the three - side gaps of the aluminum profiles. After welding is completed, the integrally welded frame is removed from the fixture bed. After removal, the other - side gap is welded. After welding is completed, a grinding machine is held by hand to grind the welding joints, and then the production of the aluminum frame is completed.

[0004] Since, during the production and welding of the aluminum frame as described above, the whole process requires the participation of workers. Moreover, during welding, not only do workers need to splice and fix it first, but also they need to hold a welding torch to weld it. This welding method not only has low efficiency, but also increases the labor of workers and reduces the overall production efficiency. Summary of the Invention

[0018] By driving the vertical threaded rod to rotate with a vertical motor, the vertical moving block and the rectangular block can be driven to move vertically.

When the welding torch moves vertically, the vertical gaps generated during splicing can be welded.

[0022] By driving the L-shaped inner clamping rod to move with the clamping pneumatic rod, when moving along with the L-shaped inner clamping rod, under the mutual cooperation of the L-shaped clamping rods, the clamping of the aluminum profile can be realized. After clamping and fixing, the 4 groups of clamping components are driven to rotate and switch by the rotating motor so that each group of clamping components can clamp, thus realizing the splicing of the aluminum profile frame;

[0023] The overall design saves floor space compared with traditional horizontal welding, thus saving resources. Brief Description of the Drawings

[0043] By driving the vertical threaded rod 544 to rotate through the vertical motor 547, the vertical moving block 545 and the rectangular block 5416 can be driven to move vertically. When the rectangular block 5416 moves, it will drive the column rod 5414 and the welding torch 5415 to move vertically.

[0047] Embodiment Two

[0048] As Figures 1 - 13 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0053] In this embodiment, the feeding mechanism 4 includes a feeding frame 41. The feeding frame 41 is installed on the top surface of the bottom plate 1.

At this time, by simultaneously conveying through the first conveying component 46 and the second conveying component 47, the aluminum profiles can be conveyed to the splicing assembly 3, facilitating subsequent splicing and subsequent welding.

[0055] Embodiment Three

[0056] As Figures 1 - 13 shown, based on the above embodiments, the following content is further given in this embodiment:

[0057] In order to splice multiple aluminum profiles into a complete aluminum frame to facilitate subsequent welding, the following technical solutions will be given in this embodiment:

[0058] The splicing assembly 3 includes a suspension rod 31. The bottom surface of the chain conveyor 2 is equidistantly installed with suspension rods 31. One side of the suspension rod 31 is fixedly connected with a rotating motor 32. The output shaft end of the rotating motor 32 is rotationally connected with a turntable 33 through a worm and a worm gear. The circumferential surface of the turntable 33 is equidistantly installed with clamping components 34, and there are 4 groups of clamping components 34. The clamping component 34 includes an L-shaped clamping rod 341. The circumferential surface of the turntable 33 is equidistantly fixedly connected with L-shaped clamping rods 341. One side of the L-shaped clamping rod 341 is fixedly connected with a convex block 342. One side of the convex block 342 is fixedly connected with a clamping pneumatic rod 343. One end of the clamping pneumatic rod 343 is fixedly connected with an L-shaped inner clamping rod 344.

[0059] The clamping pneumatic rod 343 drives the L-shaped inner clamping rod 344 to move. When moving along with the L-shaped inner clamping rod 344, the clamping of the aluminum profile can be achieved under the mutual cooperation of the L-shaped clamping rods 341. After the clamping is fixed, the rotating motor 32 drives the 4 groups of clamping components 34 to rotate and switch, so that each group of clamping components 34 can clamp, thereby realizing the splicing of the aluminum frame.

[0060] The working principle and usage process of the present invention:

[0061] In the usage state:

[0062] When in use:

[0063] First step, first, the cut aluminum profiles are conveyed into the first conveying channel 44 and the second conveying channel 45 in two states, which are the vertical state and the horizontal state respectively, so that the two groups of aluminum profiles are spliced into an "L" shape.

[0064] Second step, the chain conveyor 2 drives multiple groups of splicing assemblies 3 to rotate. When one group of splicing assemblies 3 moves to one side of the feeding mechanism 4, the chain conveyor 2 will stop working at this time.

[0065] Step 3: At this time, start the first conveying component 46 and the second conveying component 47 respectively. When the dual-axis motor 462 in the first conveying component 46 and the second conveying component 47 drives the transmission disc 463 to rotate, it can drive the conveying frame 464 to move forward. When the conveying frame 464 moves forward, the two groups of aluminum profiles can be conveyed between the L-shaped clamping rod 341 and the L-shaped inner clamping rod 344. At this time, the clamping pneumatic rod can be used to drive the L-shaped inner clamping rod 344 to move, and cooperate with the L-shaped clamping rod 341 to clamp and fix it. After clamping and fixing, at this time, the first conveying component 46 and the second conveying component 47 convey the next group of aluminum profiles. At the same time, the rotating motor 32 drives the clamping component 34 to rotate, so that the clamping component 34 surfaces of the other two groups of holes face the feeding mechanism 4, so that the feeding mechanism 4 can convey the next group of aluminum profiles in, clamp and fix it, and make the 4 groups of aluminum profiles spliced into a frame, which is convenient for later welding;

[0066] Step 4: At this time, the spliced aluminum profiles are moved to the welding mechanism 5 by the chain conveyor 2. While moving, the rotating motor 32 also needs to drive the spliced aluminum profiles to rotate by a certain angle, and the overall shape is as Figure 1 shown:

[0067] Step 5: First, the translation component 51 and the lifting hydraulic rod 52 drive the welding torch 5415 to move, so that the welding torch 5415 is located at one end of the weld seam. At this time, start the vertical motor 547. When the vertical motor 547 works, it will drive the vertical threaded rod 544 to rotate. When the vertical threaded rod 544 rotates, it will drive the vertical moving block 545 to move. When the vertical moving block 545 moves, it will drive the rectangular block 5416, the column rod 5414 and the welding torch 5415 to move vertically. When the welding torch 5415 moves, the vertical seam can be welded. When welding reaches the inflection point of the aluminum profile, at this time, the angle gear 5419 will contact the angle rack 5420, and the angle gear 5419 will rotate. At this time, the angle gear 5419 will drive the welding torch 5415 to change from a horizontal state to a vertical state. At the same time, the welding torch 5415 will also cross the inflection point. At this time, the second T-shaped block 5418 on the rectangular block 5416 will be inserted into the transverse moving block 5410. At the same time, the vertical motor 547 stops working. At the same time, the horizontal motor 548 starts to work. When the horizontal motor 548 works, it will drive the horizontal threaded rod 549 to rotate, thereby driving the transverse moving block 5410 to move. When the transverse moving block 5410 moves, it will drive the welding torch 5415 to move, and the horizontal weld can be welded. During welding, at this time, the rectangular block 5416 will be separated from the vertical moving block 545, so as to complete the welding of the 'L'-shaped seam;

[0068] Step 6: After the L-shaped gap is welded, at this time, the switching motor 534 drives the switching gear 535 to rotate. When the switching gear 535 rotates, it drives the sector rack 533 to rotate. When the sector rack 533 rotates, the welding assembly 54 can be driven to rotate 180 degrees as a whole, which also facilitates the welding of the other group of L-shaped gaps in the later stage, thereby realizing the welding of the gaps on all four sides and the splicing and welding of the two groups of aluminum profiles;

[0069] Step 7: When a set of corners of the aluminum frame is welded, at this time, the rotating motor 32 drives the clamping component 34 to rotate a certain angle, so that the unwelded corner rotates to the welding mechanism 5, and the welded corner rotates to the grinding mechanism 6 after welding;

[0070] Step 8: Through the mutual cooperation of the height hydraulic rod 61, the forward movement guide rail 62 and the translation guide rail 63, the grinding machine 65 can be moved to the weld seam for grinding. When grinding, the flipping drive 64 changes the state of the grinding machine 65. When the grinding machine 65 is in the vertical state, the two side planes of the aluminum profile can be ground by one side plane of the grinding disc. When the grinding machine 65 is in the horizontal state, the weld seam in the triangular area can be ground by the circumferential surface of the grinding disc; thus, grinding is realized, and after grinding, it is convenient to cut the material.
