Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, and in particular to a CNC double-sided laser welding and milling integrated machine. Background Technology

[0002] As industrial production demands ever higher processing efficiency, precision, and product quality, traditional cast aluminum door processing equipment and processes have gradually revealed many limitations.

[0003] In the existing technology, the processing of cast aluminum doors often relies on single-function equipment. Milling and welding processes need to be completed step by step on different equipment, which leads to complicated process connections and frequent workpiece transfers. This not only increases the risk of workpiece positioning errors but also significantly extends the production cycle and reduces the overall processing efficiency.

[0004] Meanwhile, traditional equipment lacks precise positioning and clamping mechanisms when processing cast aluminum doors. During processing, the workpiece is prone to positional displacement due to factors such as vibration and external force, which affects milling accuracy and welding quality, resulting in a decrease in product qualification rate. In addition, for the welding process, traditional equipment is difficult to detect the weld position in real time and make dynamic adjustments, which can easily lead to problems such as weld displacement and weak welding, affecting the structural stability and service life of cast aluminum doors.

[0005] In addition, traditional processing equipment has a low degree of automation. It requires a lot of manual intervention in the workpiece loading, positioning, and processing parameter adjustment stages. This not only increases the labor intensity of operators, but also makes it difficult to ensure the consistency and stability of the processing process, which is not conducive to large-scale production. Therefore, a CNC double-sided laser welding and milling integrated machine is needed. Utility Model Content

[0006] The main purpose of this utility model is to provide a CNC double-sided laser welding and milling integrated machine, which can effectively solve the problems mentioned above.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] The CNC double-sided laser welding and milling integrated machine includes a bed on which a cast aluminum door is placed. Several pairs of side clamping cylinders are provided on both sides of the inner wall of the bed to clamp and fix the cast aluminum door. The bed is provided with a positioning reference for calibrating the movement position of the cast aluminum door. Both sides of the bed are provided with rack and pinion guides, and a moving frame is provided on both rack and pinion guides. The bed is also provided with pneumatic lifting rollers for lifting the cast aluminum door.

[0009] Preferably, the two rack guides are used to drive the moving frame to move, and the moving frame is provided with two welding torch left and right control units.

[0010] Preferably, the bed is provided with a plurality of front positioning cylinders.

[0011] Preferably, the movable frame is provided with two milling cutter spindles on one side. The milling cutter spindle on one side is mounted on a rack guide rail for processing cast aluminum doors. The milling cutter follow detection sensor and the milling cutter up-and-down movement motor on one side are respectively located at the upper and lower parts of the milling cutter spindle.

[0012] Preferably, the milling cutter up-and-down motion motor is used to drive the milling cutter spindle to move, and the milling cutter follow detection sensor is used to transmit the position information of the cast aluminum door to the four welding torch left and right control units.

[0013] Preferably, two welding spindles are also provided on the other side of the movable frame. Each of the two welding spindles is equipped with a wire feeder assembly for conveying welding wire. The two welding spindles are also equipped with a laser weld seam tracking sensor, a follow-up clamping roller and a laser welding head. The two welding torch left and right control units are used to control the welding spindles to move left and right on the movable frame. Each of the two welding spindles is also equipped with a welding torch up and down movement control unit to control the up and down movement of the laser welding head.

[0014] Preferably, the laser welding head is used to perform laser welding on the cast aluminum door, the laser weld seam tracking sensor is used to detect the door seam of the cast aluminum door, and the follow-up clamping roller is used to fix the cast aluminum door to the bed frame.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model integrates milling and welding functions. By moving the movable frame on the rack guide rail, the milling and welding processes of the cast aluminum door can be completed on the same equipment. There is no need to transfer the workpiece between different equipment, which reduces the process connection time and the cumbersome process of secondary workpiece positioning. It avoids the problems of long production cycle and low efficiency caused by process separation, and improves the overall processing efficiency.

[0017] 2. This device achieves precise positioning of the cast aluminum door through a positioning reference and a front positioning cylinder. Combined with the dual fixing effect of the side clamping cylinder and the follow-up pressure roller, it can effectively avoid workpiece position deviation caused by vibration, thermal deformation, etc. during processing. At the same time, the milling cutter follow detection sensor and the laser weld seam tracking sensor can provide real-time feedback on workpiece position and weld seam information. Through the linkage adjustment of the welding torch left and right control unit, the welding torch up and down movement control unit, and the milling cutter up and down movement motor, it is ensured that the milling and welding operations are always accurately aligned with the processing position, thus improving the stability of product quality.

[0018] 3. This device uses pneumatic lifting rollers to assist in loading workpieces, reducing friction and operational intensity during manual adjustments. Each processing stage is automated through motors, cylinders, and sensors, reducing reliance on manual operation, avoiding processing errors caused by human factors, and better adapting to the needs of large-scale production.

Detailed Implementation

[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] like Figure 1 one Figure 8As shown, the CNC double-sided laser welding and milling integrated machine includes a bed 1, on which a cast aluminum door 2 is placed. Several side clamping cylinders 10 are provided on both sides of the inner wall of the bed 1 to clamp and fix the cast aluminum door 2. A positioning reference 5 is provided on the bed 1 for calibrating the moving position of the cast aluminum door 2. Both sides of the bed 1 are provided with rack guide rails 16, and a moving frame 17 is provided on both rack guide rails 16. The bed 1 is also provided with pneumatic lifting rollers 11 for lifting the cast aluminum door 2.

[0030] Furthermore, two rack guide rails 16 are used to drive the moving frame 17 to move, and the moving frame 17 is equipped with two welding torch left and right control units 3;

[0031] Furthermore, two milling cutter spindles 13 are provided on one side of the movable frame 17. The milling cutter spindle 13 located on one side is mounted on the rack guide rail 16 for processing the cast aluminum door 2. The milling cutter follow detection sensor 14 and the milling cutter up and down movement motor 12 located on one side are respectively set at the upper and lower parts of the milling cutter spindle 13.

[0032] Furthermore, the milling cutter up-and-down motion motor 12 is used to drive the milling cutter spindle 13 to move, and the milling cutter follow detection sensor 14 is used to transmit the position information of the cast aluminum door 2 to the two welding torch left and right control units 3.

[0033] Furthermore, two welding spindles are also provided on the other side of the movable frame 17. Each of the two welding spindles is equipped with a wire feeder assembly 9 for conveying welding wire. The two welding spindles are also equipped with a laser weld seam tracking sensor 6, a follow-up clamping roller 7 and a laser welding head 8. The two welding gun left and right control units 3 are used to control the welding spindle to move left and right on the movable frame 17. Each of the two welding spindles is also equipped with a welding gun up and down movement control unit 4 to control the up and down movement of the laser welding head 8.

[0034] Furthermore, the laser welding head 8 is used to perform laser welding on the cast aluminum door 2, the laser weld seam tracking sensor 6 is used to detect the door seam of the cast aluminum door 2, and the follow-up clamping roller 7 is used to fix the cast aluminum door 2 on the bed 1.

[0035] The implementation process of this device is as follows:

[0036] First, the cast aluminum door 2 to be processed is placed on the bed 1. At this time, the pneumatic lifting rollers 11 on the bed 1 are activated to gently lift the cast aluminum door 2, reducing the friction between the cast aluminum door 2 and the surface of the bed 1, making it easier for the operator to adjust the initial position of the cast aluminum door 2. The positioning reference 5 on the bed 1 serves as the basis for position calibration. The operator can fine-tune the cast aluminum door 2 by observing the relative position between the cast aluminum door 2 and the positioning reference 5. At the same time, several front positioning cylinders 15 under the bed 1 extend and apply a pushing force from the front end of the cast aluminum door 2, which, together with the positioning reference 5, completes the front and rear positioning of the cast aluminum door 2. After positioning, the side clamping cylinders 10 on both sides of the inner arm of the bed 1 extend and apply clamping force from both sides of the cast aluminum door 2, firmly clamping the cast aluminum door 2 on the bed 1, preventing position displacement due to vibration during processing.

[0037] In the above, the rack and pinion guide rails 16 on both sides of the bed 1 drive the moving frame 17 to move smoothly along the length of the bed 1. According to the processing requirements of the cast aluminum door 2, such as the starting position of milling or welding, the moving frame 17 is precisely moved to the corresponding processing area through the transmission of the rack and pinion guide rails 16, providing a positional basis for subsequent milling and welding processes.

[0038] Next, after the two milling cutter spindles 13 on one side of the moving frame 17 arrive at the milling area, the milling cutter is activated by the detection sensor 14 to detect the surface position of the cast aluminum door 2 and the contour information of the area to be milled in real time. The position information is transmitted to the two welding gun left and right control units 3 on the moving frame 17 to provide a reference for the position adjustment of the subsequent welding process. After the milling cutter up and down movement motor 12 receives the control signal, it drives the milling cutter spindle 13 to move up and down in the vertical direction. In conjunction with the horizontal movement of the moving frame 17 through the rack and pinion guide rail 16, the milling cutter on the milling cutter spindle 13 performs precise milling on the area to be processed of the cast aluminum door 2, completing milling processes such as edge trimming and surface processing.

[0039] Next, after the two welding spindles on the other side of the moving frame 17 move to the welding area, the laser weld seam tracking sensor 6 is activated to detect the position of the door seam of the cast aluminum door 2 in real time, accurately identifying the trajectory and position of the weld seam. At the same time, the follow-up pressure rollers 7 on the welding spindle move synchronously with the welding position, applying pressure from the surface of the cast aluminum door 2 to further fix the cast aluminum door 2 to the bed 1, preventing the weld seam from shifting due to thermal deformation during welding. After receiving the weld seam lateral position information transmitted by the laser weld seam tracking sensor 6, the two welding gun left and right control units 3 on the moving frame 17 accurately control the welding spindle to move left and right on the moving frame 17, ensuring that the welding spindle is always aligned with the weld seam. The laser welding head 8 moves horizontally along the weld seam trajectory. Meanwhile, the welding gun up-and-down movement control unit 4, which is installed on both welding spindles, adjusts the up-and-down movement of the laser welding head 8 in real time according to the thickness of the cast aluminum door 2, the weld depth, or the surface flatness. This ensures that the focal length between the laser welding head 8 and the weld seam is always in the optimal state, providing a guarantee for high-quality welding. After the position is adjusted, the wire feeder assembly 9 starts synchronously to feed the welding wire to the laser welding head 8. Under the coordinated control of the welding gun left and right control unit 3 and the welding gun up-and-down movement control unit 4, the laser welding head 8 moves stably along the weld seam trajectory and emits a laser beam to weld the door seam of the cast aluminum door 2. The welding wire melts under the high temperature of the laser and fills the weld seam, completing the welding process.

[0040] In the above process, after all milling and welding processes are completed, each component is reset in sequence: the milling cutter spindle 13 stops working, the milling cutter up-and-down motion motor 12 drives the milling cutter spindle 13 back to the initial height, the laser welding head 8 and the wire feeder assembly 9 stop working, the follow-up clamping roller 7 is released, the welding torch left and right control unit 3 and the welding torch up-and-down motion control unit 4 drive the welding spindle and the laser welding head 8 back to the initial position, the side clamping cylinder 10 and the front positioning cylinder 15 retract, the pneumatic lifting roller 11 maintains the lifting state, and the moving frame 17 returns to the initial position through the rack and pinion guide rail 16. The operator can then remove the finished cast aluminum door 2 from the bed 1.

[0041] In the above, the precise positioning of the cast aluminum door 2 is achieved through the positioning reference 5 and the front positioning cylinder 15. The side clamping cylinder 10 cooperates with the follow-up pressing roller 7 to ensure that the cast aluminum door 2 does not deviate during the processing, providing a foundation for high-precision processing.

[0042] The pneumatic lifting roller 11 of this device can reduce friction during the feeding and adjustment process of the cast aluminum door 2, reduce the labor intensity of operators, and at the same time avoid scratches on the surface of the cast aluminum door 2.

[0043] The rack and pinion guide 16 drives the moving frame 17 to move smoothly, ensuring the accuracy of the milling and welding positions. The milling cutter follow detection sensor 14 and the laser weld seam tracking sensor 6 provide real-time feedback on position information. With the linkage of the welding torch left and right control unit 3, the welding torch up and down motion control unit 4 and the milling cutter up and down motion motor 12, multi-dimensional precise control of milling and welding is achieved, greatly improving the processing accuracy.

[0044] This device integrates milling and welding functions, eliminating the need to transfer the cast aluminum door 2 between different machines, reducing process connection time and significantly improving processing efficiency.

[0045] This device, through the flexible adjustment of components such as the welding torch left and right control unit 3, the welding torch up and down movement control unit 4, and the milling cutter up and down movement motor 12, can adapt to cast aluminum doors 2 of different specifications and processing requirements, thus improving the versatility of the equipment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
