Description

TECHNICAL FIELD

[0001] The utility model belongs to heavy truck processing vehicle structure laser cutting technical field, especially relates to a laser cutting equipment for vehicle structural part processing. BACKGROUND

[0002] In the heavy truck manufacturing field, the advancement of welding technology plays a key role in product quality and performance. As a cutting-edge technology, heavy truck processing laser welding exhibits unique advantages in the manufacturing process. It uses a high-energy-density laser beam as a heat source. When the laser beam precisely irradiates the welding position of heavy truck components, it can instantly melt the material, enabling two or more components to fuse in a molten state, and then cool and solidify to achieve a secure connection. Compared with traditional welding methods, laser welding has a highly concentrated energy and a very small heat-affected zone, which can minimize welding deformation and effectively ensure the dimensional accuracy and structural stability of heavy truck components. It also has a fast welding speed, which can significantly improve production efficiency and fully meet the needs of heavy truck mass production. Moreover, the welding quality is high, with great strength and good sealing performance, effectively improving the overall durability and safety of heavy trucks, and playing an important role in the welding of key components such as frames, carriages, and engines, providing a solid foundation for ensuring the excellent performance and quality of heavy trucks.

[0003] At the same time, cutting technology is also an indispensable part of the vehicle manufacturing process. Chinese patent No. CN222095013U discloses a heavy truck frame cutting device. The device includes a support plate and a heavy truck frame to be cut. The support plate is provided with a laser emitter above for laser cutting. The heavy truck frame is also provided with rotatable drive main wheels and drive secondary wheels on both sides. The support plate is connected to a drive mechanism at the bottom, which is driven by a motor. The drive main wheels and drive secondary wheels rotate in opposite directions, driving the heavy truck frame to move horizontally on the support plate by friction force. This device can automatically move the heavy truck frame to different positions under the laser emitter for cutting, and has certain cutting processing function.

[0004] However, this device has obvious limitations in actual application. It can only drive a single specification of heavy truck frame to move horizontally for laser cutting. It lacks flexible adjustment and adaptation capabilities for heavy truck frames of different widths. When the width of the heavy truck frame is large, it cannot be placed between the drive secondary wheels. When the width of the heavy truck frame is small, it cannot be stably attached between the drive secondary wheels. The overall adaptation performance is poor, and it is difficult to meet the diversified vehicle manufacturing needs. Therefore, to promote the further development of the heavy truck manufacturing industry and improve production efficiency and product quality, it is urgent to improve the design of the existing heavy truck frame cutting device to achieve wider applicability and higher processing precision.

After the drive mechanism 4 is started, the first screws 22 in the sliding grooves 21 at both ends of the base 1 in the clamping mechanism 2 are driven to rotate. Since the thread rotation directions of both ends of the first screws 22 are opposite, when the first screws 22 rotate, the sliding blocks 23 threadedly connected with both ends will slide in opposite directions in the sliding grooves 21. With the movement of the sliding blocks 23, the drive assemblies 26 fixedly installed on the top of the sliding blocks 23 will also be displaced. These drive assemblies 26 can clamp the vehicle structure placed on the base 1. By adjusting the position of the sliding blocks 23, different sizes and shapes of vehicle structures can be flexibly adapted to realize stable clamping positioning.

On the other hand, the guide rollers 24 can reduce the friction between the structural parts and the concave seats 25, enabling the structural parts to move more smoothly when being clamped and adjusted in position. When the driving mechanism 4 drives the first lead screw 22 to rotate, the slider 23 and the driving assembly 26 can clamp the structural parts, and the guide rollers 24 can cooperate to ensure the stability and positional accuracy of the structural parts during the entire processing process.

[0028] Reference Figures 1-3The mounting hole 5 is provided as a counter-sunk hole, and the counter-sunk hole type mounting hole 5 provided at the four corners of the base 1 is mainly used for stably mounting the entire laser cutting device on a designated work platform or foundation. When the device is mounted, a matched bolt is used, and the head of the bolt can be sunk into the counter-sunk hole and kept flush with or slightly lower than the surface of the base 1. This design not only ensures the firmness of the device installation and avoids affecting the stability of the device placement due to the protruding bolt, but also prevents the personnel from being accidentally injured by the protruding bolt when operating around the device. At the same time, the counter-sunk hole design makes the overall appearance of the device more flat and beautiful. During the operation of the device, the stable installation can also reduce the influence of factors such as vibration on the precision and stability of the device, ensuring that each component of the laser cutting device can work stably and cooperatively when processing vehicle structural parts.

In the vehicle structure machining laser cutting equipment, the laser cutting mechanism 3 is responsible for cutting the vehicle structure positioned by the clamping mechanism 2. The support arm 31 of the laser cutting mechanism 3 is fixed to the middle of the top rear side of the base 1 to provide stable support for the whole mechanism. When the equipment starts cutting work, the electric push rod 32 is started. It is fixed at the top of the support arm 31, and its output end penetrates downward through the support arm 31, pushing the adjusting assembly 33 connected therewith to descend, thereby driving the laser cutting head 34 to approach the vehicle structure to determine the appropriate cutting starting position. The guide rail 331 in the adjusting assembly 33 is fixed to the bottom output end of the electric push rod 32. The second lead screw 332 is rotatably connected inside the guide rail 331, and the third motor 333 at the outer end provides rotating power for the second lead screw 332. After the third motor 333 is started, its output end drives the second lead screw 332 to rotate.

During use, first, the heavy truck frame is positioned and adjusted in transverse displacement by the clamping mechanism 2 to ensure that the heavy truck frame is in the best cutting position. After the position of the heavy truck frame is adjusted, the electric push rod 32 is started. The electric push rod 32 is a linear drive device, and its piston rod moves downward at a preset speed and stroke under the drive of the motor. The adjusting assembly 33 is connected with the laser cutting head 34. As the adjusting assembly 33 moves downward, the laser cutting head 34 approaches the heavy truck frame until the appropriate cutting distance is reached, realizing the cutting processing of the heavy truck frame. During the cutting process, in order to realize omnidirectional and high-precision cutting of the heavy truck frame, the device is provided with a third motor 333. After the third motor 333 is started, the motor output shaft drives the second screw 332 to rotate at a constant speed. The second screw 332 is connected with the sliding block 334 inside the guide rail 331 through threads, forming a two-stage transmission structure. When the second screw 332 rotates, the sliding block 334 slides in the guide rail 331 along the predetermined direction and trajectory by using the thread transmission principle. The bottom of the sliding block 334 is fixedly connected with the laser cutting head 34. The sliding block 334 drives the laser cutting head 34 to displace forward and backward.
