Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts cutting technology, and in particular to a cutting device for automotive parts. Background Technology
[0002] In today's booming automotive manufacturing industry, the processing precision and production efficiency of automotive parts directly affect the quality and performance of the entire vehicle. Cutting, as a key step in the parts processing, is crucial for subsequent assembly and product reliability. As the core equipment for achieving efficient and precise cutting, the performance of an automotive parts cutting device largely determines the processing quality and production pace of the parts. Therefore, optimizing and upgrading such devices to meet the high standards of modern automotive manufacturing is of great significance.
[0003] In existing technologies, cutting devices for automotive parts often employ manual screw clamping structures or simple pneumatic clamping devices when fixing the parts. Manual screw clamping structures clamp parts by rotating a screw to move a clamping plate; their technical principle utilizes the mechanical self-locking characteristic of screw transmission to fix the parts. Simple pneumatic clamping devices, on the other hand, rely on a cylinder to drive a piston, which in turn moves the clamping plate to complete the clamping action, using gas pressure to provide clamping force.
[0004] However, these fixing methods in the existing technology have obvious shortcomings. The manual spiral clamping structure relies on manual operation, which not only makes it difficult to control the clamping force accurately and easily leads to insecure clamping, but also easily causes damage to the surface of the parts if the operator applies improper force during the clamping process. The clamping force of the pneumatic simple clamping device is relatively rigid, which can also easily cause damage to some parts with high surface precision requirements. It is difficult to balance the stability of clamping and the protection of parts. Therefore, a cutting device for automotive parts is proposed to solve the above problems. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a cutting device for automotive parts, which aims to improve the problems of unstable clamping and easy damage to parts caused by manual clamping or simple fixing methods in the prior art.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0035] Reference Figures 1-4 This utility model provides an embodiment of a cutting device for automotive parts, including a worktable 1. The worktable 1 is used to support the automotive parts to be cut, providing a stable working platform. A cantilever arm 2 is fixedly connected to the side wall of the worktable 1. A cantilever arm 3 is slidably connected to the side wall of the cantilever arm 2. The cantilever arm 3 slides horizontally in conjunction with the cantilever arm 2. A slide rail 4 is slidably connected to the side wall of the cantilever arm 3. A laser cutting head 5 is slidably connected to the side wall of the slide rail 4. The laser cutting head 5 is used to emit a laser beam to cut the parts, achieving the effect of precise cutting of the parts. The cantilever arm 3, in conjunction with the slide rail 4 and the laser cutting head 5, slides in multiple directions, achieving the effect that the laser cutting head 5 can move within a large range to adapt to different cutting needs. A fixing component is provided on the upper surface of the worktable 1 to fix the parts to be cut and prevent the parts from shifting during the cutting process. A dust collection component is provided on the side wall of the cantilever arm 3 to absorb the debris and dust generated during cutting, maintaining a clean working environment.
[0036] The fixing assembly includes a clamping plate 6, which is used to directly clamp the parts and fix them in place. The side wall of the clamping plate 6 is slidably connected to the inside of the worktable 1. A slide rail 8 is fixedly connected to the bottom of the worktable 1, and a slide plate 9 is slidably connected to the side wall of the slide rail 8. The side wall of the clamping plate 6 is fixedly connected to the upper surface of the slide plate 9, and a rack 10 is fixedly connected to the upper surface of the slide plate 9. A fixing frame 11 is fixedly connected to the bottom of the worktable 1, and a motor 12 is fixedly connected to the side wall of the fixing frame 11. A gear 13 is fixedly connected to the output end of the motor 12. The gear 13 meshes with the rack 10, and the gear 13 and the rack 10 perform meshing transmission motion to achieve the rotation of the motor 12. The power is converted into the linear movement of the slide plate 9, which in turn drives the clamping plate 6 to move. A rubber pad 7 is fixedly connected to the side wall of the clamping plate 6. The rubber pad 7 is made of rubber and its function is to increase the friction between the clamping plate 6 and the parts, while preventing the clamping plate 6 from directly contacting the parts and causing scratches. The rubber pad 7 is used to reduce damage to the parts and protect the surface of the parts. The slide rail 2 8 works with the slide plate 9, and then with the rack 10 and gear 13. The motor 12 drives the gear 13 to rotate, which drives the rack 10 and the slide plate 9 to slide along the slide rail 2 8, thereby driving the clamping plate 6 to move. This achieves the effect of automatically clamping the parts and ensures the stability of the cutting process.
[0037] Reference Figures 5-6 The dust collection assembly includes a dust collection box 14 and a dust collection hood 16. The dust collection box 14 is used to collect and temporarily store the debris and fumes generated during cutting, thus achieving centralized waste disposal. The side wall of the dust collection box 14 is fixedly connected to the side wall of the cantilever arm 3. The dust collection hood 16 is used to create a negative pressure area near the cutting point to quickly absorb debris and fumes and prevent their spread. The inner wall of the dust collection hood 16 is fixedly connected to the side wall of the laser cutting head 5. The dust collection hood 16 moves synchronously with the laser cutting head 5, achieving the effect of real-time absorption of debris and fumes during the cutting process. A conveying pipe 15 is fixedly connected to the side wall of the dust collection box 14. The conveying pipe 15 is used to connect the dust collection hood 16 and the dust collection box 14, providing a conveying channel for debris and fumes. One end of the conveying pipe 15 is fixedly connected to the inner wall of the dust collection hood 16. A fan 18 is fixedly connected to the upper surface of the dust collection box 14. The fan 18 is used to generate negative pressure to provide power for the dust collection process. The suction end of the fan 18 is located inside the dust collection box 14. The fan 18 works with the dust collection box 14, the conveying pipe 15, and the dust collection hood 16 to perform suction operations, achieving the effect of forming an airflow channel from the dust collection hood 16 to the dust collection box 14, and efficiently collecting waste. A fixing sleeve 17 is fixedly connected to the side wall of the slide rail 14. The fixing sleeve 17 is used to fix the position of the conveying pipe 15 and prevent the conveying pipe 15 from shaking or getting tangled due to the movement of the laser cutting head 5. The side wall of the conveying pipe 15 is fixedly connected to the inside of the fixing sleeve 17. The conveying pipe 15 works with the dust collection hood 16 to generate negative pressure to provide power for the dust collection process. The fixing sleeve 17 is used to fix the position, ensuring the stability and smooth flow of the conveying channel. A filter screen 19 is slidably connected inside the dust collection box 14. The filter screen 19 filters debris and dust, separating solid particles from gas. A drawer 20 is slidably connected inside the dust collection box 14. The drawer 20 receives the debris filtered by the filter screen 19, facilitating subsequent cleaning. The filter screen 19, in conjunction with the drawer 20, performs filtering and collection operations, achieving waste classification and processing for easy recycling and cleaning. A locking block 21 is slidably connected inside the filter screen 19, fixing the filter screen 19 inside the dust collection box 14 to prevent it from loosening or falling off during operation. The locking block 21 has a side... The filter 19 is slidably connected to the inside of the dust collection box 14. A spring 22 is installed inside the filter 19. The function of the spring 22 is to push the locking block 21 to make tight contact with the inner wall of the dust collection box 14 through its own elasticity. One end of the spring 22 is fixedly connected to the inside of the filter 19, and the other end of the spring 22 is fixedly connected to the side wall of the locking block 21. The spring 22 cooperates with the locking block 21 to extend and retract, which achieves the effect of convenient quick installation and removal of the filter 19, and easy replacement and cleaning. The combination of components such as the fan 18, dust collection hood 16, conveying pipe 15, dust collection box 14, filter 19 and drawer 20 forms a complete dust collection and filtration system during the cutting process, which achieves the effect of efficiently removing the debris and dust generated during cutting and keeping the working environment clean.
[0038] Working principle: When using this equipment to fix parts, the motor 12 in the fixing assembly is started. The output end of the motor 12 drives the gear 13 to rotate. Since the gear 13 meshes with the rack 10 on the upper surface of the slide plate 9, the rotation of the gear 13 is converted into the sliding of the slide plate 9 on the slide rail 2 8. The clamping plate 6 is fixedly connected to the upper surface of the slide plate 9. Therefore, the sliding of the slide plate 9 will drive the clamping plate 6 to move synchronously. By the mutual approach of the two clamping plates 6, the parts on the worktable 1 are clamped and fixed. The rubber pads 7 on the side walls of the clamping plates 6 can reduce damage to the parts during the clamping process. During the cutting operation, the cantilever arm 2 3 can slide on the side wall of the cantilever arm 1 2, the slide rail 1 4 can slide on the side wall of the cantilever arm 2 3, and the laser cutting head 5 can slide on the side wall of the slide rail 1 4. Through the cooperation of these three, the laser cutting head 5 can move flexibly in three-dimensional space, thereby achieving precise cutting. Align the parts with the area to be cut and complete the cutting operation. During the cutting process, the vacuuming components work simultaneously. The fan 18 on the upper surface of the vacuum box 14 is activated, creating negative pressure inside the vacuum box 14 at its suction end. Since the vacuum hood 16 is connected to the vacuum box 14 through the conveying pipe 15, the negative pressure is transmitted to the vacuum hood 16 through the conveying pipe 15, causing the cutting debris and dust to be sucked in by the vacuum hood 16 and then conveyed to the vacuum box 14 through the conveying pipe 15. The conveying pipe 15 is fixed to the side wall of the slide rail 4 by the fixing sleeve 17, ensuring the stability of the vacuuming process. The debris and dust entering the vacuum box 14 are filtered by the filter screen 19, and the debris falls into the drawer 20 for easy cleaning. The filter screen 19 is fixed inside the vacuum box 14 by the cooperation of the clip 21 and the spring 22, making it easy to remove and replace the filter screen 19 to ensure the filtration effect.
