Description

Technical Field

[0001] This invention relates to the field of laser cutting technology, specifically a laser cutting device for the production of parts for road clearing vehicles. Background Technology

[0002] Wrecker vehicles are essential specialized vehicles for roadside assistance and vehicle transportation. Their manufacturing involves the processing of numerous metal components, such as tow arms, crossbeams, reinforcing plates, and connecting seats. These components are typically made of medium-thick steel plates or profiles, and come in various shapes, including complex cutting contours such as straight lines, curves, and bevels, requiring high cutting precision and efficiency. Laser cutting, due to its advantages such as narrow kerf, small heat-affected zone, and high cutting speed, is widely used in the production of wrecker vehicle components.

[0003] Currently, laser cutting equipment used for pipes and profiles is mostly a three-axis or five-axis linkage cutting machine tool. The workpiece is clamped on a chuck or support roller, and the cutting is completed through the multi-axis movement of the cutting head. However, existing equipment still has the following shortcomings in practical applications: First, the attitude adjustment range of the cutting head is limited. For beveling processing that requires oblique cutting at multiple angles in the circumferential direction of pipes or profiles, the cutting head often requires a complex robotic arm structure, resulting in high equipment cost and insufficient rigidity. Second, the workpiece conveying and support mechanisms are mostly fixed, making it difficult to adapt to different cross-sectional sizes and shapes of clearing vehicle accessories, and inconvenient for changeover and adjustment. Third, during the cutting process, the workpiece is only limited by one side of the bottom support roller or side positioning wheel. For accessories with asymmetrical cross-sections or off-center centers of gravity, they are prone to flipping or tilting during conveying, affecting cutting accuracy.

[0004] Therefore, there is an urgent need for a laser cutting device that can flexibly adjust the spatial posture of the cutting head, adapt to the stable conveying of various cross-section parts, and has a compact structure and good rigidity, so as to improve the efficiency and quality of the production of parts for clearing vehicles. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. This invention, by setting a rotating ring mechanism, can drive the deflection ring mechanism and the rotating mounting sleeve mechanism to rotate and change position as a whole. In conjunction with the deflection ring mechanism, the overall deflection angle of the laser cutting head is adjusted, and the displacement ring mechanism can synchronously adjust the angle of multiple laser cutting heads.

[0042] The workflow of this invention is as follows:

[0043] The workflow of the laser cutting device for producing parts for the clearing vehicle can be divided into five stages: parameter adjustment, workpiece clamping and conveying, cutting head posture adjustment, laser cutting operation, and unloading. The actions of the components involved in each stage are detailed below.

[0044] I. Parameter Adjustment Stage

[0045] Based on the cross-sectional dimensions and length of the parts to be cut for the clearing vehicle, three sets of parameters are adjusted. The second linear motor 702 is activated, driving the moving frame 703 to move laterally along the base 1. The distance between the two moving frames 703 is adjusted to accommodate the width of the parts. The third linear motor 801 is activated, driving the lower support roller seat 802 to rise and fall, which in turn drives the upper support roller seat 901 to move synchronously in the opposite direction via the synchronizing rod mechanism 10. Specifically, when the lower slider 1010 moves with the lower support roller seat 802, the linkage of the fourth rotating seat 1009, the second rotating rod 1008, the telescopic block 1006, the first rotating rod 1004, and the upper slider 1002 causes the upper support roller seat 901 to move in the opposite direction along the upper sliding groove 1001, achieving synchronous adjustment of the distance between the lower support roller 804 and the upper support roller 904, thus centering and limiting the movement of the parts. Start the fourth linear motor 1101 to drive the moving plate 1102 to move axially, and adjust the axial position of the lower support wheel 1103 and the side chuck wheel 1104 to adapt to the length support requirements of the accessories.

[0046] II. Workpiece clamping and conveying stage

[0047] The part to be cut is fed into the device from one end. The bottom of the part is supported by the lower support roller 804 and the lower support wheel 1103, the side is limited by the side retaining wheel 1104, and the top is pressed by the upper support roller 904, forming a multi-point stable clamping. The third motor 902 is started to drive the upper support roller 904 to rotate. The upper support roller 904 drives the part to be conveyed longitudinally by friction, and conveys the part to the central cutting area of ​​the rotating ring mechanism 2.

[0048] III. Cutting Head Posture Adjustment Stage

[0049] According to the cutting path requirements, the posture of the laser cutting head 6 is adjusted in multiple dimensions. The first motor 206 is started, and through the meshing transmission of gear 207 and gear ring 204, it drives the rotating ring 203 to rotate around the transverse axis within the mounting ring 202, causing the deflection ring mechanism 3 and the laser cutting head 6 mounted on it to rotate and change position, thus altering the circumferential cutting position of the laser cutting head 6. The second motor 304 is started, and through the drive shaft 303, it drives the deflection ring 302 to deflect around the axis of the deflection shaft 301, adjusting the overall pitch angle of the laser cutting head 6. The first linear motor 503 is started, and its telescopic end pushes the displacement ring 506 to rotate relative to the deflection ring 302. The displacement ring 506 drives the rotating rod 404 to swing through the second rotating shaft seat 406 and the second rotating shaft 405. The rotating rod 404 drives the mounting sleeve 402 to rotate around the rotating seat 401 through the first rotating shaft 403, achieving synchronous adjustment of the radial cutting angles of multiple laser cutting heads 6. The coordinated operation of all axes ensures that the laser cutting head 6 accurately reaches the starting position for cutting.

[0050] IV. Laser Cutting Operation Stage

[0051] The laser cutting head 6 is activated, and the part is cut according to the preset cutting program. During the cutting process, the first motor 206, the second motor 304, the first linear motor 503, and the third motor 902 work together in real time according to the cutting path to achieve continuous control of the cutting trajectory and synchronous feeding of the workpiece. The lower support wheel 1103 and the side chuck wheel 1104 of the support wheel mechanism 11 continuously provide auxiliary support to the bottom and sides of the part during the cutting process to prevent the part from flipping or tilting due to cross-sectional asymmetry or center of gravity offset.

[0052] V. Material Feeding Stage

[0053] After cutting is completed, the laser cutting head 6 stops working. The third motor 902 continues to drive the upper support roller 904 to rotate, sending the cut part out of the cutting area. All motion mechanisms reset, ready for the next workpiece cutting operation.

[0054] 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, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
