Description

Technical Field

[0001] This utility model relates to the field of cutting fixture technology, specifically to a laser cutting fixture for processing automotive longitudinal beams. Background Technology

[0002] Longitudinal beams play a crucial load-bearing role in automobiles. Both side-beam and center-beam chassis contain longitudinal beams, which are typically stamped from low-alloy steel sheets. The manufacturing process of automotive longitudinal beams involves multiple processing steps, including laser cutting, welding, and stamping. Currently, when cutting automotive longitudinal beams, multiple clamps are usually used to hold and fix them side-by-side. However, automotive longitudinal beams can be straight or curved in the horizontal direction. In passenger cars, the frame is often widened in the middle for easier vehicle mounting, making the curvature more complex. In the vertical direction, longitudinal beams often have variable cross-sections, sometimes bending downwards at the front and arching upwards at the front and rear suspensions of passenger cars. When using multiple clamps to cut and hold automotive longitudinal beams, the clamps need to be adjusted sequentially, resulting in a lengthy adjustment and clamping time, which can easily reduce the efficiency of clamping and cutting the longitudinal beams.

[0049] Please see Figures 1 to 4A laser cutting fixture for machining automotive longitudinal beams includes a base plate 1, a cutting table 2, a support base, a placement plate 3, a movable plate 4, positioning clamping rods 5, a moving assembly, and a clamping assembly. The cutting table 2 is disposed on the upper side of the base plate 1, and the support base is disposed between the cutting table 2 and the base plate 1. The placement plate 3 is fixedly connected to the center of the cutting table 2. Two movable plates 4 are provided, which are movable towards each other on both sides of the placement plate 3. Multiple positioning clamping rods 5 are provided, which are respectively fixedly connected to the two movable plates 4, and positioning clamping pads 6 are fixedly connected to the positioning clamping rods 5 to stably clamp the bottom of the automotive longitudinal beam. The moving assembly is disposed on the two movable plates 4. Between the moving plates 4, there are two clamping components, which are respectively set on the two moving plates 4. Two feeding plates 25 are symmetrically and obliquely connected on the cutting table 2, and two support rods 23 are fixedly connected between the feeding plates 25 and the base plate 1, which can stably support the feeding plates 25. At the same time, the two feeding plates 25 can quickly load and unload the automobile longitudinal beam on the cutting table 2.

[0050] refer to Figure 1 as well as Figure 2 The clamping assembly includes a main clamping plate 7, a middle clamping plate 8, a secondary clamping plate 9, clamping rods 10, clamping pads 11, sliding blocks 12, and a fixed seat. The main clamping plate 7 is movably mounted on an adjacent movable plate 4. The middle clamping plate 8 is slidably mounted on one side of the main clamping plate 7. The secondary clamping plate 9 is movably mounted on one side of the middle clamping plate 8. Multiple clamping rods 10 are provided, and multiple clamping rods 10 are fixedly connected between the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9. The clamping pads 11 are fixedly connected to each clamping rod 10. Multiple sliding blocks 12 are provided, and multiple sliding blocks 12 are fixedly connected to the bottom ends of the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9. The movable plate 4 has a sliding groove for the sliding blocks 12 to slide. The fixed seat is provided between the multiple sliding blocks 12.

[0051] The main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9 can be moved on the movable plate 4 respectively. The clamping range between the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9 can be adjusted according to the specifications of the automobile longitudinal beam, so that multiple clamping rods 10 and multiple clamping pads 11 can stably clamp different parts of the automobile longitudinal beam.

[0052] refer to Figure 2The fixed base includes a fixed frame 13, a fixed rod 14, a fixed plate 15, and a fixed strip 16. The fixed frame 13 is detachably connected to one side of the movable plate 4. The fixed rod 14 is fixedly connected to the fixed frame 13 and passes through the movable plate 4 between the adjacent sliding block 12. There are two fixed plates 15, which are symmetrically slidably connected to both sides of the fixed frame 13. The fixed frame 13 has a fixing opening for the fixed plates 15 to slide. There are two fixed strips 16, which are fixedly connected to the two fixed plates 15 respectively and pass through the movable plate 4 between the adjacent sliding block 12.

[0053] When the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9 move on the upper side of the moving plate 4, multiple sliding blocks 12 also move within the sliding groove. After the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9 have all moved to the appropriate positions, two fixing strips 16 are inserted between the moving plate 4 and the corresponding two sliding blocks 12, and a fixing bracket 13 is installed between two fixing plates 15. At the same time, a fixing rod 14 is inserted between the moving plate 4 and the corresponding sliding block 12, thereby fixing multiple sliding blocks 12 on the moving plate 4, which facilitates the fixing of the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9, and improves the stability of the multiple clamping rods 10 and the multiple clamping pads 11 in clamping the automotive longitudinal beam.

[0054] refer to Figure 3 The moving assembly includes a protective frame 17, a double-headed electric cylinder 18, moving bars 19, connecting rods 20, and moving rods 21. The protective frame 17 is fixedly connected to the top of the base plate 1. The double-headed electric cylinder 18 is installed inside the protective frame 17, which protects the double-headed electric cylinder 18 and reduces the impact of cutting debris on it. Two moving bars 19 are provided, and they are fixedly connected to the output ends of the double-headed electric cylinder 18. Multiple connecting rods 20 are provided. The connecting rod 20 is fixedly connected between the two moving bars 19 and the two moving plates 4 respectively, and the cutting table 2 is provided with a connecting port for the connecting rod 20 to move. There are two moving rods 21, and both moving rods 21 are fixedly connected to the bottom end of each moving bar 19. The bottom plate 1 is provided with a moving groove for the moving rod 21 to move. When the moving bar 19 moves, the moving rod 21 will move in the moving groove, which improves the stability of the support of the moving bar 19 and the stability of the movement of the moving rod 21.

[0055] When the double-headed electric cylinder 18 is started, the two moving bars 19 move towards each other, which can cause the multiple connecting rods 20 to drive the two moving plates 4 to move towards each other. When the two moving plates 4 approach each other, the multiple positioning clamps 5 will gradually approach the longitudinal beam of the car, so that the multiple positioning clamps 5 and the multiple positioning pads 6 will quickly and stably clamp the bottom of the longitudinal beam of the car.

[0056] refer to Figure 4 The support base includes a support pad 22, a support rod 23, and a shock-absorbing pad 24. Multiple support pads 22 are provided, and multiple support pads 22 are fixedly connected to the top of the base plate 1. The support rod 23 is fixedly connected to the top of each support pad 22, and the shock-absorbing pad 24 is fixedly connected between each support rod 23 and the cutting table 2.

[0057] Multiple support rods 23, multiple support pads 22, and multiple shock-absorbing pads 24 can stably support the cutting table 2, thereby enabling the cutting table 2 and the placement plate 3 to stably support the automotive longitudinal beam. At the same time, the support pads 22 and the shock-absorbing pads 24 can reduce the impact of the vibration generated when the automotive longitudinal beam is laser-cut on the support rods 23 and the base plate 1.

[0058] In summary, the automotive longitudinal beam to be laser-cut is first placed on the placement plate 3. Based on the specifications of the automotive longitudinal beam, the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9 are moved on the moving plate 4. The clamping range between the main clamping plate 7, the middle clamping plate 8, and the secondary clamping plate 9 is adjusted. Once all three plates are in the appropriate positions, the fixing rod 14 and the fixing strip 16 are inserted between the moving plate 4 and the corresponding sliding block 12 to fix their positions. Then, the double-headed electric cylinder 18 is activated, causing the two moving strips 19 to move the two moving plates 4 via multiple connecting rods 20. When the two moving plates 4 move towards each other, multiple positioning clamping rods 5 and multiple positioning clamping pads 6 quickly clamp the bottom of the automotive longitudinal beam. Simultaneously, multiple clamping rods 10 and multiple clamping pads 11 quickly and stably clamp other parts of the automotive longitudinal beam, thereby improving the stability of the automotive longitudinal beam cutting clamping.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
