[0015] Preferably, a third drive motor is installed on one side of the second mounting frame, an output end of the third drive motor is fixedly connected to the screw rod, and four corners of the bottom of the second mounting frame are fixedly connected to support legs.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, when the rotating frame rotates, it not only drives the first mounting frame and the fixed plate to rotate together, but also makes the entire system perform circular motion around the rotating frame, thereby ensuring flexible and coordinated multi-directional cutting. At the same time, the rotation of the rotating rod activates the active bevel gear, thereby driving the driven bevel gear and the center rod, so that the first linkage rod and the two second linkage rods produce a linkage effect. Through the cooperation of the first connecting rod and the first transmission rod, the activity of the second transmission rod is controlled, thereby accurately controlling the movement of the connecting frame, completing the linear and rotational motion of the laser cutter and the moving plate.

[0017] 2. In the present invention, the first drive motor drives the rotating rod to rotate smoothly. Its design avoids interference with the rotating frame, enhances the reliability of the system and provides space for free movement. When the second drive motor is running, the active gear drives the driven gear to rotate the rotating frame, and the whole drives the synchronous movement of the first mounting frame and the fixed plate. This linkage design ensures the coordination of the system and improves work efficiency. During the movement, the first belt connects the first synchronous wheel and the second synchronous wheel to ensure stable transmission, enhance the stability of the moving plate and the center rod, and improve the processing accuracy. In addition, the first transmission rod rotates around the first mounting frame, and the connection with the second linkage rod and the first connecting rod introduces more linkage mechanisms, further coordinates the cooperation of multiple components, and improves the response speed and work efficiency. This multi-level motion coordination mechanism enables the equipment to flexibly respond to complex processing requirements and ensure efficient and precise processing of automotive parts.

[0018] 3. In the present invention, during the cutting operation, the cylinder accurately controls the height of the fixed plate to provide a suitable working height for the cutting mechanism. This adjustment capability makes the cutting process more flexible and efficient, ensuring the accuracy of the cutting depth and angle. At the same time, the third drive motor drives the screw to rotate and pushes the moving block, so that the placement plate can effectively adjust the position of the parts. To enhance stability, the guide block slides freely on the surface of the slide rod, effectively limiting the deflection of the placement plate, ensuring that it always remains on the correct track to avoid skewing or offset. Before the actual cutting, the coordinated operation of the four positioning clamps provides positioning for the parts, further improving the stability of the cutting. These positioning clamps effectively fix the parts to prevent shaking caused by vibration or external force, thereby ensuring the accuracy and consistency of the cutting.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1 - Figure 6 As shown: A cutting device for processing automobile parts, comprising a base plate 1, two support frames 2 are symmetrically fixedly connected to the top of the base plate 1, two cylinders 4 are installed at the bottom of the support frames 2, a cutting mechanism 3 is connected to the top of the cylinder 4, and a moving mechanism 5 is installed at the center of the top of the base plate 1; The cutting mechanism 3 includes a fixed plate 31, a limiting sleeve 312 is fixedly connected to the bottom center of the fixed plate 31, a rotating frame 34 is rotatably connected to the inner side of the limiting sleeve 312, a first mounting frame 341 is fixedly connected to both sides of the middle of the rotating frame 34, and a fixed plate 31 is fixedly connected to the bottom end of the rotating frame 34, a center rod 37 is rotatably connected to the inner side of the fixed plate 31, a driven bevel gear 371 is fixedly connected to the outer surface of one end of the center rod 37, a first linkage rod 372 is fixedly connected to the outer surface of the middle of the driven bevel gear 371, and a second linkage rod 372 is rotatably connected to both sides of the bottom end of the first linkage rod 372. 73, the bottom end of the second linkage rod 373 is rotatably connected to the first connecting rod 374, one end of the first mounting frame 341 is rotatably connected to the first transmission rod 38, the bottom end of the first transmission rod 38 is rotatably connected to the first connecting rod 374, the outer surface of one end of the first connecting rod 374 is rotatably connected to the second transmission rod 381, the bottom end of the second transmission rod 381 is rotatably connected to the second connecting rod 382, ​​the bottom end of the second connecting rod 382 is rotatably connected to the connecting frame 391, the bottom of the connecting frame 391 is fixedly connected to the movable plate 39, and the bottom center of the movable plate 39 is fixedly connected to the laser cutter 392.

[0023] In this embodiment, when the rotating frame 34 rotates, it not only drives the first mounting frame 341 and the fixed plate 31 to rotate together, but also makes the entire system perform a circular motion around the rotating frame 34. This motion design enables flexible coordination between components, which is particularly important when multi-directional cutting is required.

[0024] At the same time, when the rotating rod 321 rotates, the active bevel gear 322 will rotate accordingly, and then exert a force on the driven bevel gear 371, so that the center rod 37 starts to rotate. This process is a key power transmission link. The rotation of the center rod 37 will not only drive the first linkage rod 372 to rotate, but also control the movement of the two second linkage rods 373 through the first linkage rod 372. At this time, the two second linkage rods 373 will start to move at the same time, generating a linkage effect, thereby transmitting the force to the first connecting rod 374.

[0025] In this case, the first connecting rod 374 drives the second transmission rod 381 to move through the first transmission rod 38, forming an efficient mechanical linkage system. This system enables multiple components to work together to control the movement of the connecting frame 391. Through this collaboration, the laser cutter 392 and the moving plate 39 can be precisely controlled to perform linear movement and rotational movement.

[0026] In general, the rotation of the rotating frame 34 and the rotation of the rotating rod 321 complement each other to form a highly coordinated motion mechanism. This mechanism can flexibly adjust the movement mode of the laser cutter 392, not only to achieve straight-line cutting, but also to move in complex arc trajectories, ensuring accurate cutting and high efficiency in the processing of automotive parts. It can greatly improve the flexibility and accuracy of processing, meet the processing requirements of parts of different shapes and sizes, and thus optimize the entire production process.

[0027] Embodiment 2: Figure 3 - Figure 6 As shown, one end of one of the first mounting frames 341 is fixedly connected to the second belt 36, and one end of one of the first connecting rods 374 is fixedly connected to the first belt 35. The first synchronous wheel 351 is sleeved on the outer surface of one end of the first belt 35, and the second synchronous wheel 352 is sleeved on the surface of the other end of the first belt 35. One end of the first synchronous wheel 351 is sleeved on the outer surface of the second belt 36, and the third synchronous wheel 361 is sleeved on the outer surface of one end of the second synchronous wheel 352, and one end of the third synchronous wheel 361 is fixedly connected to the second connecting rod 382. Two mounting plates 311 are symmetrically fixedly connected to the top of the fixed plate 31, one side of one of the mounting plates 311 is fixedly connected to the first drive motor 32, and one side of the other mounting plate 311 is fixedly connected to the second drive motor 33. The output end of the first driving motor 32 is fixedly connected with a rotating rod 321, the bottom end of the rotating rod 321 passes through the rotating frame 34, and the bottom end of the rotating rod 321 is rotatably connected to the fixed plate 31, and the outer surface of the bottom end of the rotating rod 321 is fixedly connected with a driving bevel gear 322, and the driving bevel gear 322 is meshed and connected with the driven bevel gear 371. The outer surface of the top end of the rotating frame 34 is fixedly connected with a driving gear 331, and one side of the driving gear 331 is meshed and connected with a driven gear 332, and the driven gear 332 is fixedly connected with the output end of the second driving motor 33.

[0028] In this embodiment, the rotating rod 321 can rotate smoothly through the drive of the first driving motor 32, and its design ensures that it will not interfere with the rotating frame 34 during the rotation process. This non-interference structural design not only improves the reliability of the system, but also provides space for the free movement of the rotating rod 321.

[0029] When the second driving motor 33 is running, the rotation of the driving gear 331 directly applies force to the driven gear 332, thereby driving the rotating frame 34 to rotate. During the movement of the rotating frame 34, the first mounting frame 341 and the fixing plate 31 will move as a whole. This linkage design ensures the coordination and synchronization of the system and improves work efficiency.

[0030] During the activity, the movement of the moving plate 39 and the center rod 37 is also well supported. The two ends of the first belt 35 are respectively connected to the first synchronous wheel 351 and the second synchronous wheel 352. This design ensures a stable transmission effect, making the entire system more stable during movement. At the same time, the cooperation between the second belt 36 and the third synchronous wheel 361 further enhances the stability of the moving plate 39, ensuring that its height does not change during the movement, thereby improving the processing accuracy.

[0031] In addition, the first transmission rod 38 rotates around the first mounting bracket 341 and is connected to the first connecting rod 374 with the second linkage rod 373. This design introduces more linkage mechanisms in the entire system, making the movement more coordinated. Under this linkage, the coordinated work of multiple components is achieved, further improving the response speed and work efficiency of the system. Through this multi-level motion coordination mechanism, the entire device can more flexibly respond to complex processing requirements and ensure high efficiency and precision in processing automotive parts.

[0032] Embodiment 3: According to Figure 7 As shown, the moving mechanism 5 includes a second mounting frame 51, a screw rod 56 is rotatably connected to the center of the inner side of the second mounting frame 51, a moving block 55 is threadedly connected to the outer surface of the screw rod 56, and a storage plate 57 is fixedly connected to the top of the moving block 55. Slide rods 53 are arranged on both sides of the screw rod 56, both ends of the slide rod 53 are fixedly connected to the second mounting frame 51, and two guide blocks 54 are slidably connected to the outer surface of the slide rod 53. The two sides of the bottom of the storage plate 57 are fixedly connected to the two guide blocks 54, and two positioning clamps 58 are symmetrically installed on both sides of the top of the storage plate 57. A third driving motor 52 is installed on one side of the second mounting frame 51, and the output end of the third driving motor 52 is fixedly connected to the screw rod 56, and the four corners of the bottom of the second mounting frame 51 are fixedly connected to support legs 59.

[0033] In this embodiment, during the cutting operation, the operation of the air cylinder 4 precisely controls the height of the fixed plate 31, thereby providing a suitable working height for the cutting mechanism 3. This adjustment capability makes the cutting process more flexible and efficient, ensuring the accuracy of the cutting depth and angle.

[0034] At the same time, the operation of the third drive motor 52 drives the screw rod 56 to rotate, prompting the moving block 55 on the outer surface of the screw rod 56 to start moving. In this process, the moving block 55 further promotes the movement of the storage plate 57, so that the position of the components above the storage plate 57 can be effectively adjusted. In order to enhance stability, the guide block 54 is designed to be able to slide freely on the surface of the slide bar 53. This feature effectively limits the deflection of the storage plate 57 during movement, ensuring that it always stays on the correct track and avoids skewing or offset.

[0035] Before the actual cutting, the four positioning clamps 58 work together to position the parts, thereby further improving the stability of the cutting process. These positioning clamps 58 can effectively fix the parts to prevent shaking caused by vibration or other external forces during the cutting process, ensuring the accuracy and consistency of the cutting.

[0036] The use method and working principle of this device: When the rotating frame 34 rotates, it will drive the first mounting frame 341 and the fixed plate 31 to rotate together, thereby realizing a circular motion centered on the rotating frame 34. At the same time, the rotation of the rotating rod 321 will drive the active bevel gear 322 to rotate, and then exert a force on the driven bevel gear 371, so that the center rod 37 starts to rotate. In this process, the center rod 37 will not only drive the first linkage rod 372 to rotate, but also control the movement of the two second linkage rods 373. The two are turned on at the same time and transmit the force to the first connecting rod 374, so that it drives the second transmission rod 381 to move through the first transmission rod 38, and cooperates to control the movement of the connecting frame 391. In addition, the laser cutter 392 and the moving plate 39 will move in a straight line to ensure precise cutting during the processing of automotive parts and support the movement of arc-shaped trajectories.

[0037] Driven by the first drive motor 32, the rotating rod 321 rotates without interfering with the rotating frame 34. The operation of the second drive motor 33 drives the driving gear 331 to rotate, and then the driven gear 332 drives the rotating frame 34 to rotate. At this time, the movement of the rotating frame 34 will also drive the first mounting frame 341 and the fixed plate 31 to move as a whole. When the moving plate 39 and the center rod 37 are moving, the first belt 35 connects the first synchronous wheel 351 and the second synchronous wheel 352 to provide stability. At the same time, the second belt 36 works with the third synchronous wheel 361 to ensure that the moving plate 39 is highly stable when moving. The first transmission rod 38 also rotates around the first mounting frame 341, further linking the second linkage rod 373 and the first connecting rod 374.

[0038] During the cutting operation, the air cylinder 4 controls the height of the fixed plate 31 to facilitate the operation of the cutting mechanism 3. The third drive motor 52 drives the screw 56 to rotate, so that the moving block 55 on the outer surface moves, further driving the placement plate 57 to move and control the position of the top parts. The guide block 54 slides on the surface of the slide bar 53 to limit the stability of the placement plate 57 and prevent it from deflecting. Before cutting, the coordinated operation of the four positioning clamps 58 ensures the positioning of the parts to prevent shaking during cutting.

[0039] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
