[0002] The instrument panel tube beam is the solid foundation of the instrument panel assembly and an important component connecting the vehicle architecture and passenger safety. During the production and processing of automotive tube beams, cutting tools are typically used to cut the instrument panel tube beam into specific shapes and sizes according to design requirements. This ensures the precise fit between the instrument panel tube beam and the instrument panel system and other automotive components, thereby improving the assembly accuracy and stability of the entire vehicle.

[0003] Currently, during the cutting process of instrument panel tube beams, burrs are usually generated on the cut surface of the tube beam. The presence of burrs can easily reduce the flatness of the cut surface of the tube beam, thereby reducing the fitting accuracy between the tube beam and other components, and thus affecting the assembly quality and performance of the entire vehicle. Therefore, this utility model proposes a cutting device for instrument panel tube beams. Utility Model Content

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example: Please refer to Figure 1-4 This utility model provides a technical solution: a cutting device for instrument panel beams, comprising a mounting plate 1, a cutting table 11 fixedly connected to the top of the mounting plate 1, a partition plate 12 fixedly connected to the inner side wall of the mounting plate 1, two long plates 2 fixedly connected to the top of the cutting table 11, a cutting blade 21 rotatably connected between the two long plates 2, two short plates 22 fixedly connected to the top of the cutting table 11, an active rod 23 rotatably connected between the two short plates 22, both ends of the active rod 23 penetrating the side wall of the short plate 22 and fixed. The cutting table 11 and the partition 12 are equipped with a grinding block 24. The top of both the cutting table 11 and the partition 12 are provided with two sets of sliding grooves 25. The top of the cutting table 11 is slidably connected with two clamps 26. The bottom of each clamp 26 is fixedly connected with a slide rod 27. The bottom end of each slide rod 27 passes through the cutting table 11 and the partition 12 through the sliding grooves 25. The bottom of the partition 12 is slidably connected with a push plate 28. Both ends of the push plate 28 are provided with transverse grooves 29. The bottom end of each slide rod 27 is slidably connected to the push plate 28 through the transverse grooves 29.

[0021] Two long plates 2 are rotatably connected to the outer sides of a central gear 3. One end of each central gear 3 passes through the side wall of the long plate 2 and is fixedly connected to the cutting blade 21. Two driven gear rings 31 are rotatably connected to the outer sides of the two long plates 2, and the driven gear rings 31 mesh with the central gear 3. Two driving gear rings 32 are fixedly connected to the outer side wall of the driving rod 23. A transmission belt 33 is connected between the driving gear rings 32 and the driven gear rings 31. Two mounting blocks 34 are fixedly connected to the top of the cutting table 11. A drive shaft 35 is rotatably connected between the drive shaft 35 and the drive rod 23. A short drive belt 36 is sleeved between the drive shaft 35 and the drive rod 23. By setting the long drive belt 33 and the short drive belt 36, the drive shaft 35 drives the drive rod 23 to rotate through the short drive belt 36. The drive rod 23 drives the drive gear ring 32 on its outer side to rotate. The drive gear ring 32 drives the driven gear ring 31 to rotate through the long drive belt 33. The driven gear ring 31 drives the central gear 3 to rotate. The central gear 3 drives the cutting blade 21 to rotate between the two long plates 2.

[0022] A threaded rod 4 is rotatably connected to the inner wall of the mounting plate 1. The push plate 28 is threadedly sleeved on the outer wall of the threaded rod 4. Two limiting plates 41 are fixedly connected to the bottom of the partition plate 12. The push plate 28 is slidably connected between the two limiting plates 41. By setting the threaded rod 4 and the limiting plates 41, during the rotation of the threaded rod 4, under the limiting action of the two limiting plates 41, the threaded rod 4 drives the push plate 28 on its outer side to slide between the two limiting plates 41.

[0023] A first motor 7 is fixedly connected to the outer wall of the mounting block 34. The output end of the first motor 7 passes through the side wall of the mounting block 34 and is fixedly connected to the transmission shaft 35. A second motor 71 is fixedly connected to the outer wall of the mounting plate 1. By setting the first motor 7 and the second motor 71, the first motor 7 is started, so that the first motor 7 drives the transmission shaft 35 to rotate between the two mounting blocks 34 through the output end. The second motor 71 is started, so that the second motor 71 drives the threaded rod 4 to rotate inside the mounting plate 1 through the output end.

[0024] A spacer ring 5 is fixedly connected to the center of each of the two driven gear rings 31. By setting the spacer ring 5, the transmission belt 33 and the central gear 3 are separated, preventing the transmission belt 33 from contacting the central gear 3, thereby protecting the transmission belt 33.

[0025] Two pairs of fixing rods 6 are fixed to the top of the cutting table 11, and fixing blocks 61 are fixed to the top of each pair of fixing rods 6. By setting the fixing blocks 61, the tube beam inside the clamp 26 is resisted, preventing the tube beam from sliding inside the clamp 26 under the squeezing action of the grinding block 24, thereby improving the grinding effect of the grinding block 24 on the tube beam.

[0026] The bottom of the mounting plate 1 is fixed with four support legs 8. By setting the support legs 8, the stability of the overall device is increased, and the overall device is prevented from tilting or sliding during operation.

[0027] Working principle: By starting the first motor 7, the first motor 7 drives the transmission shaft 35 to rotate between the two mounting blocks 34 through its output end. Under the transmission action of the short transmission belt 36, the transmission shaft 35 drives the driving rod 23 to rotate between the two short plates 22. The driving rod 23 drives the two driving gear rings 32 on its outer side to rotate. Under the transmission action of the long transmission belt 33, the two driving gear rings 32 drive the two driven gear rings 31 to rotate through the long transmission belt 33. Under the meshing action of the driven gear rings 31 and the central gear 3, the two driven gear rings 31 rotate. The ring 31 drives the central gear 3 on its upper side to rotate. The two central gears 3 drive the cutting blade 21 to rotate between the two long plates 2. By starting the second motor 71, the second motor 71 drives the threaded rod 4 to rotate inside the mounting plate 1 through the output end. The threaded rod 4 drives the outer pushing long plate 28 to slide between the two limiting plates 41. Under the limiting action of the transverse groove 29, the pushing long plate 28 drives the slide rod 27 to slide along the vertical end of the sliding folding groove 25 through the transverse groove 29. The slide rod 27 drives the clamp 26 at its top to slide along the vertical end of the sliding folding groove 25. The two clamps 26 drive the internal tube beams to move towards the cutting blade 21. Under the rotation of the cutting blade 21, the cutting blade 21 cuts and severs the tube beams between the two clamps 26, pushing the long plate 28 to continue sliding along the inclined end of the sliding groove 25 via the transverse groove 29. The two pairs of sliding rods 27 drive the two clamps 26 to move along the inclined end of the sliding groove 25, causing the two clamps 26 to move the internal tube beams closer to both sides of the cutting table 11, pushing the long plate 28 through the transverse groove 29 to drive the sliding rods 27 and the other side of the sliding groove 25. One vertical end slides, and the slide rod 27 drives the clamp 26 to slide along the other vertical end of the sliding groove 25. The two clamps 26 drive the internal tube beams to move closer to the grinding block 24. The active rod 23 drives the grinding blocks 24 at both ends to rotate on both sides of the mounting block 34. Under the action of the stop of the fixed block 61, the rotating grinding block 24 grinds and polishes the tube beams inside the two clamps 26, thereby removing burrs on the tube beam cutting surface, improving the flatness of the tube beam cutting surface, and thus improving the fitting accuracy of the tube beam with other parts, and improving the assembly quality and performance of the whole vehicle.
