[0002] The frame structure of some new energy vehicles uses beveled steel pipes. Through special design and connection methods, beveled steel pipes can form a stable frame structure, providing support and load-bearing capacity for the vehicle. Steel pipe bevel cutting is an important technology in metal processing, mainly used to prepare for subsequent processes such as welding and connection of steel pipes.

[0017] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are merely examples, and those skilled in the art may conceive of other obvious variations.

[0018] like Figure 1-Figure 7 The flat-plate bevel laser cutting machine shown includes a processing table 1, and several support frames 2 are fixedly installed on the rear surface of the processing table 1. The upper ends of the several support frames 2 are commonly fixedly installed with a top frame 3. A laser cutting mechanism is provided on the inner side of the top frame 3, and a lifting plate 18 is installed on the front surface of the top frame 3 through a lifting mechanism. A guide opening 23 is opened through the upper surface of the lifting plate 18, and a sliding seat 24 is slidably connected to the inner side of the guide opening 23 through a distance adjustment mechanism. A first baffle 26 is rotatably installed on the lower end of the sliding seat 24, and a second baffle 30 is rotatably installed on the lower surface of the lifting plate 18 and on the side away from the first baffle 26. Positioning plates 34 are respectively provided on the front and rear edges of the upper surface of the processing table 1, and the two positioning plates 34 are connected by a telescopic mechanism.

[0019] like Figure 2 、 Figure 3As shown, the laser cutting mechanism includes a first screw rod 4 that rotates through the inner side of the top frame 3, a first guide rod 5 is fixedly installed on the inner side of the top frame 3 and away from the side of the first screw rod 4, and a longitudinal slide 6 is respectively provided below the first screw rod 4 and the first guide rod 5. A plurality of first connecting seats 7 are fixedly installed on the upper surface of the longitudinal slide 6. The first connecting seat 7 on one side is threadedly sleeved on the outer surface of the first screw rod 4, and the first connecting seat 7 on the other side is slidably sleeved on the outer surface of the first guide rod 5. A first motor 8 is fixedly installed on the rear surface of the top frame 3, and the output shaft of the first motor 8 is fixedly connected to the rear end of the first screw rod 4. A laser cutting head 14 is installed between the two longitudinal slides 6 through a transverse slide mechanism. The operation of the first motor 8 causes the first screw rod 4 to rotate, thereby causing the longitudinal slide 6 on this side to move back and forth, changing the front and rear position of the laser cutting head 14, and the longitudinal slide 6 on the other side slides back and forth along the surface of the first guide rod 5 to ensure the stability of the movement.

[0020] The transverse slide mechanism includes a second connecting seat 11 fixedly connected to the front and rear edges of the lower surface of the longitudinal slide 6, a second guide rod 10 fixedly connected between the second connecting seats 11 on both sides in the front, and a second screw rod 9 rotatably connected between the second connecting seats 11 on both sides in the rear, one end of the second screw rod 9 fixedly connected to the output shaft of the second motor 12, and the second motor 12 is fixedly mounted on the lower surface of the longitudinal slide 6, the outer surface of the second screw rod 9 is threadedly connected to the transverse slide 13, the second guide rod 10 slides through the inner side of the transverse slide 13, and the upper end of the laser cutting head 14 is fixedly mounted on the lower surface of the transverse slide 13. The operation of the second motor 12 causes the second screw rod 9 to rotate, thereby causing the transverse slide 13 to move laterally, changing the transverse position of the laser cutting head 14 to complete the cutting action. At the same time, the transverse slide 13 moves laterally along the surface of the second guide rod 10 to ensure stability during movement.

[0021] like Figure 2 As shown, the lifting mechanism includes a sleeve 15 fixedly mounted on the front edge of the top frame 3. A vertical guide plate 16 slides through the upper surface of the sleeve 15. The upper end of the vertical guide plate 16 is fixedly connected to the telescopic end of a lifting cylinder 17. The lower end of the lifting cylinder 17 is fixedly mounted on the upper surface of the sleeve 15, and the lower end of the vertical guide plate 16 is fixedly connected to the front of the lifting plate 18. When the lifting cylinder 17 is extended or retracted, the vertical guide plate 16 will slide vertically, causing the lifting plate 18 to move up and down. The sleeve 15 can improve the stability of the vertical guide plate 16 during movement.

[0022] like Figure 4 、 Figure 5As shown, the pitch adjustment mechanism includes side plates 19 fixedly mounted on the upper surface of the lifting plate 18 and near both sides. A threaded rod 21 is rotatably connected between the two side plates 19. One end of the threaded rod 21 is fixedly connected to the output shaft of a third motor 22, which is also fixedly mounted on the side surface of the side plate 19. A threaded sleeve 28 is fixedly connected to the upper surface of the sliding seat 24. The threaded rod 21 threads through the inner side of the threaded sleeve 28. It is used to control the lateral movement of the first baffle 26, thereby pushing the steel pipe.

[0023] A first rotary motor 27 is fixedly mounted on the rear edge of the upper surface of the sliding base 24. The output shaft of the first rotary motor 27 is fixedly connected to a first rotating shaft 25. The first rotating shaft 25 rotates through the inner side of the sliding base 24, and the lower end of the first rotating shaft 25 is fixedly connected to the upper edge of the first baffle 26. Rotation of the first rotary motor 27 causes the first rotating shaft 25 to rotate the first baffle 26, thereby changing the tilt angle.

[0024] A mounting base 29 is fixedly mounted on the upper surface of the lifting plate 18, away from the first baffle 26. A second rotary motor 32 is fixedly mounted on the upper surface of the mounting base 29. The output shaft of the second rotary motor 32 is fixedly connected to a second rotating shaft 31. The second rotating shaft 31 rotates through the inner side of the mounting base 29, and the lower end of the second rotating shaft 31 is fixedly connected to the upper edge of the second baffle 30. The second rotary motor 32 drives the second rotating shaft 31 to rotate, thereby rotating the second baffle 30. It should be noted that the rotation of the first rotary motor 27 and the second rotary motor 32 always remain synchronized.

[0025] like Figure 6 As shown, the telescopic mechanism includes a bidirectional telescopic cylinder 35 fixedly mounted on one side of the processing table 1, and the two telescopic ends of the bidirectional telescopic cylinder 35 are respectively connected to the outer edge of the positioning plate 34. It is used to control the two positioning plates 34 to move closer to or away from each other.

[0026] like Figure 1 As shown, the front and rear edges of the lower surface of the processing table 1 are respectively fixedly mounted with a pad 33. To elevate the processing table 1, to facilitate operations such as the placement of steel pipes.

[0027] The user lays a number of steel pipes on the surface of the processing table 1, and then controls the lifting cylinder 17 to retract, so that the vertical guide plate 16 and the lifting plate 18 move downward, and the lifting plate 18 stops when it is close to the surface of the steel pipe. Then the third motor 22 is controlled to operate, and when the threaded rod 21 rotates, the first baffle 26 and the second baffle 30 move closer to each other, and the pushing effect causes the flat steel pipes to become inclined. During this process, the lower surface of the lifting plate 18 will limit the steel pipes to prevent the problem of upward stacking between the steel pipes during extrusion. After stopping, the two-way telescopic cylinder 35 is controlled to retract, so that the two positioning plates 34 are close to each other, and then the front and rear ends of the inclined side-by-side steel pipes are pushed so that the edges of the front and rear ends respectively press against the positioning plates 34. At this time, a number of steel pipes are in a horizontally flat state, as shown in FIG. Figure 7 As shown, as the laser cutting head 14 moves horizontally, each steel pipe can be beveled near the rear end to form a groove, which has the function of automatically tilting, positioning, arranging and quickly cutting batches of steel pipes, thereby improving processing efficiency.

[0028] By controlling the first rotating motor 27 and the second rotating motor 32 to rotate at the same angle, the tilt state of the arranged steel pipe can be changed to match the movement of the laser cutting head 14 to form grooves with different slopes, which is flexible and convenient to operate.
