Description

Technical Field

[0001] This utility model relates to the field of vehicle frame production, and in particular to a cutting device for vehicle frame production. Background Technology

[0002] Currently, when using laser processing technology to produce frame tubing, in order to improve processing efficiency and simplify the processing process, laser drilling of the frame tubing is usually performed simultaneously with laser cutting. This integrated processing method effectively shortens the overall production cycle of the frame and reduces equipment investment costs, and has been widely recognized and applied in the field of frame production.

[0003] However, in actual production, it was found that waste generated during processing would be directly left inside the internal cavity of the frame tubes due to gravity or airflow during processing. This waste left inside the tubes required manual cleaning later, which was time-consuming and labor-intensive. A search revealed that Chinese utility model patent CN202411403129.7 discloses a related frame processing waste treatment technology. This patent, by setting a specific waste collection structure on the processing equipment, has achieved the collection of waste generated during processing to a certain extent, alleviating the problem of waste remaining inside the frame tubes. However, in practical application, this technical solution still has certain limitations: its waste collection structure is mainly for waste that splashes to the outside of the equipment or near the tube port during processing. For residual waste that has penetrated deep into the tube during laser drilling or is stuck in special structures inside the tube, the collection effect is limited, and it is still difficult to achieve efficient and thorough removal of residual waste inside the frame tubes.

[0023] Furthermore, "several" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0024] This utility model discloses a cutting device for vehicle frame production. (Refer to...) Figure 1-5A cutting device for vehicle frame production includes a feeding mechanism 1, a clamping mechanism 2, a laser cutting mechanism 3, a protective box 5, and a cleaning mechanism 4. The feeding mechanism 1 and the protective box 5 are respectively arranged on both sides of the laser cutting mechanism 3. The cleaning mechanism 4 is integrated inside the protective box 5. The feeding mechanism 1 can drive the vehicle frame tubes to move horizontally and rotate circumferentially to meet the needs of different processing positions. The cleaning mechanism 4 specifically includes a fixed platform 41, a fan, an air duct 42, a guide platform 43, a guide rod 44, a spring 45, a telescopic plate 46, and a corrugated hose 47. The fixed platform 41 is fixedly installed inside the protective box 5. A guide platform 43 is positioned on top of a fixed platform 41. A guide rod 44 extends horizontally through the guide platform 43 and slides through it. One end of the guide rod 44 near the laser cutting mechanism 3 is vertically fixedly connected to a telescopic plate 46. A spring 45 is coaxially sleeved on the outside of the guide rod 44, with one end of the spring 45 abutting against the side of the telescopic plate 46 away from the guide platform 43, and the other end abutting against the side of the guide platform 43 near the telescopic plate 46. A ventilation opening 48 is provided in the middle of the telescopic plate 46, which is coaxial with the axis of the clamping mechanism 2 when clamping the frame tube. A fan is embedded inside the fixed platform 41. One end of the duct 42 is sealed to the air outlet of the fan, and the other end of the duct 42 passes horizontally through the guide table 43 and extends to the side of the guide table 43 near the telescopic plate 46. One end of the corrugated hose 47 is sealed to the end of the duct 42 that extends out of the guide table 43, and the other end is sealed to the edge of the ventilation opening 48 on the telescopic plate 46. This design drives the frame tubes to move and rotate through the feeding mechanism 1, and can cooperate with the laser cutting mechanism 3 to complete all-round cutting and drilling operations. The protective box 5 can effectively block the splashing of waste materials and laser radiation during the processing. In the cleaning mechanism 4, the spring 45 and the guide rod The cooperation of 44 allows the telescopic plate 46 to adaptively adjust its position when in contact with the frame tube, ensuring that the vent 48 is always precisely aligned with the tube end. The airflow generated by the fan is delivered to the vent 48 through the air duct 42 and the corrugated hose 47, and can directly blow air into the tube to efficiently remove residual waste. The telescopic nature of the corrugated hose 47 adapts to the positional changes of the telescopic plate 46. The overall structure is compact and the various mechanisms are highly coordinated, which not only ensures the synchronization of processing and cleaning, but also improves the thoroughness of waste removal and the adaptability of the equipment to frame tubes of different lengths. At the same time, it reduces the cost of manual cleaning and improves production efficiency.

[0025] A wing beam 49 is provided on the vent 48. The purpose of the wing beam 49 is to prevent small-diameter frame tubes from being inserted into the vent 48 during processing.

[0026] During actual processing, the frame tubes are continuously conveyed towards the laser cutting mechanism 3 under the drive of the feeding mechanism 1. After the laser cutting mechanism 3 completes the cutting operation of a section of the frame tube, the telescopic plate 46, which was originally compressed due to the contact of the tube, will move away from the guide table 43 along the guide rod 44 under the elastic restoring force of the spring 45, returning to its initial position. After the telescopic plate 46 is reset, the feeding mechanism 1 continues to drive the subsequent frame tubes forward. During the conveying process, the end of the new frame tube will contact the telescopic plate 46 again and push the telescopic plate 46 to compress the spring 45, so that the telescopic plate 46 re-contracts with the guide table 43. The ends of the tubes fit tightly together, ensuring that the vent 48 remains coaxially aligned with the tube. During this process, the vent 48 continuously blows high-pressure air into the tube. The airflow pushes the waste in the current processing section of the tube into the uncut subsequent tube section. As the tube continues to be fed and cut into sections, the waste accumulates and is transferred in the subsequent tube sections until the last section of the frame tube is cut and continues to be conveyed forward by the feeding mechanism 1. At this point, the airflow blown by the vent 48 will directly blow all the waste accumulated in the last section of the tube out of the tube, achieving the centralized and thorough discharge of waste during the processing of the entire frame tube.

[0027] The laser cutting mechanism 3 includes a fixed frame 31, a horizontal moving module 32, a vertical moving module 33, and a laser cutting head 34. The fixed frame 31 is connected to the end of the protective box 5 to form a relatively closed processing space. The horizontal moving module 32 is fixedly installed on the top of the fixed frame 31 in the horizontal direction. The vertical moving module 33 is set on the moving end of the horizontal moving module 32 in the vertical direction. The laser cutting head 34 is detachably installed on the moving end of the vertical moving module 33. The horizontal moving module 32, the vertical moving module 33, and the laser cutting head 34 are all located in the closed space formed by the connection between the fixed frame 31 and the protective box 5. The side wall of the fixed frame 31 near the protective box 5 has a feed port 35 that is coaxial with the ventilation port 48 of the telescopic plate 46 in the cleaning mechanism 4.

[0028] The clamping mechanism 2 includes a symmetrically arranged clamping assembly 21 and a clamping assembly 22. The clamping assembly 22 is correspondingly arranged at the feed inlet 35 of the fixed frame 31. The clamping assembly 22 specifically includes four sets of drive arms 221, four sets of sliders 222, four sets of slide blocks 223, and four sets of rollers 224. The four sets of drive arms 221 and the four sets of slide blocks 223 are all fixed in a circular array on the side wall outside the feed inlet 35 of the fixed frame 31. The output end of each set of drive arms 221 is fixedly connected to one end of the corresponding slider 222. Each set of sliders 222 and the corresponding slide block 223 slide in a radial direction. One end of each set of clamping arms 221 is vertically fixed to the side of the corresponding slider 222 away from the drive arms 221. Each set of rollers 224 is rotatably connected to the corresponding slider 222 via bearings. The clamping arm 221 should be positioned inside the end away from the slider 222. The four sets of drive units can synchronously drive the corresponding slider 222 to slide radially inward along the slide block 223, thereby driving the roller 224 at the end of the clamping arm 221 to clamp inward synchronously to fix the frame tube. With this design, the fixing frame 31 and the protective box 5 are connected to form a closed space, which can effectively prevent the leakage of strong light and the splashing of waste during laser processing, ensuring operational safety. The horizontal moving module 32 and the vertical moving module 33 work together to drive the laser cutting head 34 to achieve precise movement in the horizontal and vertical directions, meeting the cutting and drilling needs of different positions of the frame tube. In addition, the feed port 35 and the ventilation port 48 are coaxially designed, providing a smooth channel for the subsequent cleaning mechanism 4 to blow air into the tube to clean up waste.

[0029] The clamping assembly 21 includes a turntable 211, a drive unit 212, a clamping block 212, a rotating shaft 213, a bearing seat 214, a movable box 215, a motor, a drive wheel 216, a driven wheel 217, and a belt 218. The movable box 215 is slidably connected to the feeding mechanism 1. The bearing seat 214 is fixed to the top of the movable box 215. The rotating shaft 213 is connected to the bearing seat 214. One end of the rotating shaft 213 is connected to the turntable 211. The driven wheel 217 is fixed to the other end of the rotating shaft 213. The drive wheel 216 and the driven wheel 217 are tensioned by the belt 218. The motor is located inside the movable box 215. The output end of the motor is connected to the drive wheel 216. At least two sets of clamping blocks 212 and drive unit 212 are provided. Drive unit 212 is located inside the turntable 211. The clamping block 212 is slidably engaged with the turntable 211. The output end of drive unit 212 is connected to the clamping block 212.

[0030] The clamping assembly 21 includes a turntable 211, a drive unit, a clamping block 212, a rotating shaft 213, a bearing housing 214, a movable box 215, a motor, a drive wheel 216, a driven wheel 217, and a belt 218. The movable box 215 is slidably connected to the frame of the feeding mechanism 1 via a slide rail or groove, and can move horizontally as driven by the feeding mechanism 1. The bearing housing 214 is bolted to the top of the movable box 215, and the rotating shaft 213 is rotatably connected to the bearing housing 214 via bearings. Inside the bore, one end of the rotating shaft 213 is connected to the center of the turntable 211 by a key or welded. The driven wheel 217 is fixed to the other end of the rotating shaft 213 away from the turntable 211 by a flat key. The driving wheel 216 and the driven wheel 217 are connected by a belt 218 to form a tension transmission. The motor is fixedly installed inside the movable box 215 by a motor mount, and the end of the motor's output shaft is fixedly connected to the driving wheel 216 by a flat key. The clamping block 212 and the drive are each provided with at least two sets in opposite directions. The drive unit (which can be a cylinder, hydraulic cylinder, or electric push rod) is fixed in the mounting cavity inside the turntable 211 via a mounting base. The clamping block 212 slides with the guide groove on the end face of the turntable 211 via a slider 222. The output end of each drive unit is fixedly connected to the back of the corresponding clamping block 212 via a flange or pin. With this design, the sliding engagement between the moving box 215 and the feeding mechanism 1 can drive the clamping assembly 21 to move horizontally synchronously with the processing requirements of the frame tubes, meeting the clamping requirements of tubes of different lengths. At the same time, the motor drives the rotating shaft 213 and the turntable 211 to rotate via the drive wheel 216, belt 218, and driven wheel 217, which can cooperate with the feeding mechanism 1 to realize the circumferential rotation of the frame tubes, facilitating the laser cutting mechanism 3 to perform all-round cutting and drilling on the outer circumference of the tubes. At the same time, at least two sets of symmetrically arranged drive units and clamping blocks 212 can push the clamping blocks 212 to slide along the guide groove through the drive unit, realizing stable clamping of frame tubes of different diameters.

[0031] The feeding mechanism 1 includes a feeding frame 11 and a drive unit 3. The movable box 215 is slidably connected to the feeding frame 11. The output end of the drive unit 3 is connected to the movable box 215. The drive unit 3 drives the movable box 215 to move horizontally. The drive unit 3 can be a ball screw module, a gear and rack transmission mechanism or an electric push rod. It is fixedly installed on one side of the feeding frame 11 along the length direction of the feeding frame 11. The output end of the drive unit 3 is fixedly connected to the side wall of the movable box 215 through a coupling or a connecting flange. When the drive unit 3 is working, it can drive the movable box 215 to move horizontally and reciprocally along the slide rail of the feeding frame 11 to realize the horizontal feeding of the frame tubes.
