Description

Technical Field

[0001] The invention relates to the technical field of aluminum profile laser welding, and in particular to a laser welding machine for automatic docking aluminum profile processing. Background Art

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

[0003] At present, when aluminum profiles are welded into aluminum frames, first, the staff cuts the entire aluminum profile into the required length, and then moves the aluminum profile to the clamp bed. At this time, the clamp on the clamp bed can clamp and fix the aluminum profile. While clamping, the aluminum profiles are also butted in pairs for later welding. When the aluminum profiles are spliced ​​and fixed, the staff holds the welding gun and starts to weld the gaps on three sides of the aluminum profile. After the welding is completed, the overall welded frame is removed from the clamp bed, and then the gap on the other side is welded. After the welding is completed, the grinder is held in hand to grind the welded part, and the production of the aluminum frame is completed.

[0004] Because when the aluminum frame is produced and welded, the entire process requires the participation of workers, and when welding, not only do the workers need to splice and fix it first, but they also need to hold the welding gun to weld it. This welding method is not only inefficient, but also increases the labor of the workers, while also reducing the overall production efficiency. Summary of the invention

When the rectangular block moves, it will drive the column and the welding gun to move vertically. When the welding gun moves vertically, the vertical gap generated during splicing can be welded.

[0022] 5. The L-shaped inner clamp rod is driven to move by the clamping pneumatic rod. When the L-shaped inner clamp rod moves, the aluminum profile can be clamped with the cooperation of the L-shaped clamp rods. After the clamping is fixed, the four groups of clamping parts are driven by the rotating motor to rotate and switch, so that each group of clamping parts can clamp, thereby realizing the splicing of the aluminum frame;

[0055] Embodiment 3

[0056] like Figure 1-Figure 13 As shown, based on the above embodiment, this embodiment further provides the following contents:

[0057] In order to realize the splicing of multiple sections of aluminum profiles into a complete aluminum frame, thereby facilitating subsequent welding, this embodiment will provide the following technical solutions:

[0058] The splicing assembly 3 includes a suspension rod 31, and the suspension rods 31 are evenly spaced on the bottom surface of the chain conveyor 2.

When the L-shaped inner clamping rod 344 moves, the aluminum profile can be clamped with the cooperation of the L-shaped clamping rod 341. After the clamping is fixed, the four groups of clamping components 34 are driven by the rotating motor 32 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 use process of the present invention:

[0061] In use:

[0062] When using:

[0063] In the first step, the cut aluminum profiles are conveyed to the first conveying channel 44 and the second conveying channel 45 in two states, namely, a vertical state and a horizontal state, so that the two groups of aluminum profiles are spliced ​​in an "L" shape;

[0064] In the second step, the chain conveyor 2 drives the multiple groups of splicing components 3 to rotate. When one group of splicing components 3 moves to one side of the feeding mechanism 4, the chain conveyor 2 will stop working;

[0065] The third step, at this time, the first conveying assembly 46 and the second conveying assembly 47 are started respectively, when the dual-axis motor 462 in the first conveying assembly 46 and the second conveying assembly 47 drives the transmission plate 463 to rotate, the conveying frame 464 can be driven 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 L-shaped inner clamping rod 344 can be driven to move by the clamping pneumatic rod, and the L-shaped clamping rod 341 is clamped and fixed in cooperation with each other, after clamping and fixing, at this time, the first conveying assembly 46 and the second conveying assembly 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 components 34 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, clamp and fix them, and make the four groups of aluminum profiles spliced ​​into a frame, which is convenient for later welding;

[0066] In the fourth step, the spliced ​​aluminum profiles are moved to the welding mechanism 5 by the chain conveyor 2. While moving, the rotating motor 32 is required to drive the spliced ​​aluminum profiles to rotate a certain angle. The overall shape is as follows: Figure 1 As shown:

[0067] The fifth step, first, the welding gun 5415 is driven to move by the translation assembly 51 and the lifting hydraulic rod 52, so that the welding gun 5415 is located at one end of the weld. At this time, the vertical motor 547 is started. When the vertical motor 547 works, it will drive the vertical threaded rod 549 to rotate. When the vertical threaded rod 549 rotates, it will drive the vertical block 545 to move. When the vertical block 545 moves, it will drive the rectangular block 5416, the column 5414 and the welding gun 5414 to move vertically. When the welding gun 5414 moves, the welding of the vertical gap can be realized. When it is welded to the inflection point of the aluminum profile, the angle gear 5419 at this time will contact the angle rack 5420, and the angle gear 5419 The angle gear 5419 will drive the welding gun 5415 to change from a horizontal state to a vertical state. At the same time, the welding gun 5415 will also pass the inflection point. At this time, the second T-block 5418 on the rectangular block 5416 will be inserted into the transverse block 5410. At the same time, the vertical motor 547 stops working, and the transverse motor 548 starts working. When the transverse motor 548 is working, it will drive the transverse threaded rod 549 to rotate, thereby driving the transverse block 5410 to move. When the transverse block 5410 moves, it will drive the welding gun 5415 to move, so as to realize the welding of the horizontal weld. During welding, at this time, the rectangular block 5416 will be separated from the vertical block 545, thereby completing the welding of the 'L'-shaped gap.

[0068] Step 6. After the L-shaped gap is welded, the switching motor 534 is used to drive the switching gear 535 to rotate. When the switching gear 535 rotates, the sector gear 533 is driven to rotate. When the sector gear 533 rotates, the welding assembly 54 can be driven to rotate 180 degrees as a whole, which will facilitate the welding of another set of L-shaped gaps in the later stage, thereby realizing the welding of the gap parts on four sides and the splicing welding of two sets of aluminum profiles.

[0069] Step 7: When the aluminum frame has finished welding a group of corners, the rotating motor 32 will drive the clamping component 34 to rotate a certain angle, so that the unwelded corners are rotated to the welding mechanism 5, and after the welding is completed, the corners are rotated to the grinding mechanism 6;

[0070] In the eighth step, through the cooperation of the high-pressure hydraulic rod 61, the forward guide rail 62 and the translation guide rail 63, the grinder 65 can be moved to the weld, and after grinding it, during grinding, the flip drive 64 changes the state of the grinder 65. When the grinder 65 is in a vertical state, the side plane of the grinding disk can be used to grind the two side planes of the aluminum profile. When the grinder 65 is in a horizontal state, the circumferential surface of the grinding disk can be used to grind the weld in the triangular area; thereby, grinding is achieved, and after grinding, the material can be unloaded conveniently.
