Description

Technical Field

[0001] This invention belongs to the field of laser welding technology, and more specifically, relates to an intelligent welding system for a multifunctional self-unloading semi-trailer. Background Technology

[0002] The processing of dump semi-trailers utilizes laser welding technology, primarily due to its advantages of high precision, high efficiency, and high strength. Laser welding enables deep penetration welding and narrow weld seams, significantly improving the connection strength of key stress-bearing parts of the chassis while reducing thermal deformation and ensuring the dimensional stability of large components. Laser-welded seams are more aesthetically pleasing and require no subsequent grinding, meeting the dual demands of lightweighting and aesthetics in modern commercial vehicles. It is a core process for improving the durability and production efficiency of semi-trailers.

[0003] For example, patent application number CN202223519391.7 discloses a semi-trailer parts welding device, including a base plate, a welding platform plate, and a support frame. The top center of the base plate is provided with an adjustment mechanism, the middle of the welding platform plate is provided with a placement mechanism, the top of the connecting block passes through the middle of the support frame and is provided with a pneumatic telescopic rod, the output end of the pneumatic telescopic rod passes through the middle left side of the fixed frame and the middle of the welding platform plate and is fixedly connected to the bottom left end of the welding frame, the welding frame is slidably connected to the slide groove, the slide groove is set on the fixed frame, and the right end of the welding frame is provided with a welding head. In this utility model, the pneumatic telescopic rod fixed on the connecting block, as well as the fixed base frame, welding frame, and welding head, are adjusted in angle as a whole by the motor drive, and then the welding frame and welding head are driven by the pneumatic telescopic rod to weld the parts up and down in the slide groove.

[0004] Based on the above, the laser welding equipment currently in use still has the following problems: 1. It lacks an automatic welding penetration detection structure, which makes it inconvenient for staff to inspect the quality of laser welding; 2. When manually inspecting the welding penetration, staff still need to adjust the distance between the laser welding head and the metal part to be inspected, and it is impossible to achieve automatic adjustment of the height of the laser welding head.

[0052] Furthermore, since the rectangular adjusting rod 304 is fixedly installed on the rear side of the polygonal mounting tube 302, and the adjusting tilt bracket 407 is fixedly installed on the top of the adjusting bracket 406, and the adjusting tilt bracket 407 is also in contact with the rectangular adjusting rod 304, when the output shaft of the drive motor b405 drives the circular mounting shaft 402 to rotate 90 degrees, the polygonal mounting tube 302 can slide upward a certain distance under the action of the rectangular adjusting rod 304 and the adjusting tilt bracket 407, realizing the automatic adjustment of the distance between the laser welding head 305 and the two rectangular detection plates 404, thus enabling the detection of welding penetration depth.

When the drive screw 103 drives the rectangular mounting block a201 to slide to the left, the circular auxiliary rod 502 can separate the two welded rectangular detection plates 404, making it convenient for the staff to observe the weld penetration depth.

[0053] The specific usage and function of this embodiment are as follows:

[0054] When using this invention, the workers first use bolts to fix the linear guide rail 101 on the welding fixture for the self-unloading semi-trailer parts, ensuring that the height of the weld is flush with the height of the linear guide rail 101. The height of the laser welding head 305 is then adjusted appropriately, and the adjusted laser welding head 305 is positioned by two limiting threaded pins 306.

[0055] When the drive motor b405 is started, its output shaft drives the circular mounting shaft 402 to rotate 90 degrees. As the output shaft rotates the circular mounting shaft 402, the two rectangular detection plates 404 move directly below the laser welding head 305. The laser welding head 305 is controlled by an external welding machine to weld the gap between the two rectangular detection plates 404. When the output shaft rotates the circular mounting shaft 402 90 degrees, the polygonal mounting tube 302 slides upward a certain distance under the action of the rectangular adjusting rod 304 and the adjusting tilt bracket 407, thus achieving the connection between the laser welding head 305 and the two rectangular detection plates 404. The automatic adjustment of the distance between 04 makes the welding penetration depth detection more accurate. The operator inserts his finger into the separation through hole 4031 and pushes the two rectangular detection plates 404 after welding upwards to separate the two rectangular detection plates 404 from the rectangular rotating plate 403. Then, one of the rectangular detection plates 404 after welding is inserted into the positioning groove 5011, and the drive motor b405 is started, so that the drive screw 103 drives the rectangular mounting block a201 to slide to the left. At this time, the circular auxiliary rod 502 can separate the two rectangular detection plates 404 after welding, making it easier for the operator to observe the welding penetration depth. When the welding penetration depth does not meet the welding quality requirements, the operator can adjust the height of the laser welding head 305 or adjust the welding parameters of the welding machine.

[0056] During welding, the operator starts the drive motor a104 and the external laser welding machine. When the output shaft of the drive motor a104 rotates forward, the rectangular mounting block a201 moves to the left and right; when the output shaft of the drive motor a104 rotates in reverse, the rectangular mounting block a201 moves to the right and left, thus realizing the reciprocating movement of the rectangular mounting block a201.
