[0021] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.
[0022] This utility model embodiment provides a combined aerospace aluminum alloy longitudinal beam structure for a portable laser cutting machine, which can solve the problems of difficult processing and forming of longitudinal beams, long processing cycle, and difficulty in ensuring processing accuracy in related technologies.
[0023] See Figure 1 As shown in the illustration, a combined aerospace aluminum alloy longitudinal beam structure for a portable laser cutting machine according to an embodiment of this utility model includes: a first beam 1 with a rack mounting surface 11 on the top; the first beam 1 is rectangular in shape with a central control section, an arc-shaped top, and a flat bottom; the rack mounting surface 11 is located at both ends of the top; at least two second beams 2 of the same shape are symmetrically engaged with opposite sides of the first beam 1; the second beams 2 are provided with optical axis mounting grooves 21; the second beams 2 are trapezoidal in shape, with the shorter top edge connected to the first beam 1 and the longer bottom edge located on the outside; the top of the second beams 2 has a flat surface on which a rack can be mounted, and the bottom is inclined. By using beams of simple shapes combined into a longitudinal beam structure, the shape can be simplified, materials saved, the processing process simplified, the processing cycle shortened, and the processing accuracy improved without affecting the overall strength.
[0024] See Figure 1 As shown, in some embodiments, the outer ends of the first beam 1 are provided with a first slot 12 and a second slot 13, and the two ends of the second beam 2 are provided with a first block 22 that matches the first slot 12 and a second block 23 that matches the second slot 13. By setting slots and blocks at the upper and lower ends respectively, the connection between the beams is secured, ensuring the stability of the connection between the beams and increasing the overall strength.
[0025] See Figure 1 As shown, in some embodiments, the first slot 12 and the second slot 13 are oriented downwards, and the first block 22 and the second block 23 are both L-shaped. By making the slots oriented downwards and the blocks oriented upwards, the relative movement of the first beam 1 and the second beam 2 can be restricted in the height direction, further ensuring the stability of the connection between the beams.
[0026] See Figure 1 As shown, in some embodiments, the bottom of the first beam 1 is provided with a bolt mounting groove 14, and a bolt 15 is installed in the bolt mounting groove 14. The second slot 13 communicates with the bolt mounting groove 14, and the second block 23 is adjacent to the bolt 15. By installing the bolt 15, a nut is installed at the lower end of the bolt 15. The bottom of the second block 23 abuts against the top of the nut, thereby restricting the relative movement of the two beams in the height direction. The inner side of the second block 23 abuts against the screw, and the outer side abuts against the side wall of the bolt mounting groove 14, thereby restricting the relative movement of the two beams in the width direction, further ensuring the stability of the connection between the beams.
[0027] See Figure 1As shown, in some embodiments, the top of the second beam 2 is provided with a boss 24, which is located on the side of the second beam 2 away from the first beam 1. By providing the boss 24, the bottom of the slider equipped with the laser cutting machine is provided with a matching groove, so that the shape of the slider and the longitudinal beam are matched, thereby increasing the stability of the slider movement during operation.
[0028] See Figure 1 As shown, in some embodiments, the optical axis mounting groove 21 is disposed on the outside of the boss 24, and the optical axis is installed in the optical axis mounting groove 21. The thickness of the outside of the boss 24 is greater than the thickness of other positions. By setting the optical axis mounting groove 21 here, the strength of the optical axis mounting position can be guaranteed, thereby increasing the strength of the longitudinal beam under stress and reducing damage.
[0029] See Figure 1 As shown, in some embodiments, the optical axis mounting groove 21 is formed by bending the outer side of the second beam 2 inward. By bending the optical axis mounting groove 21 inward to form a semi-circle, and setting the outer side as a semi-open, it can play a role in protecting the optical axis.
[0030] See Figure 1 As shown, in some embodiments, the first beam 1 is provided with a first reinforcing rib 16 inside. The two ends of the first reinforcing rib 16 are respectively connected to the top and bottom of the first beam 1, which can increase the strength of the first beam 1 and reduce the deformation of the beam.
[0031] See Figure 1 As shown, in some embodiments, the second beam 2 is provided with a second reinforcing rib 25 inside. The two ends of the second reinforcing rib 25 are respectively connected to the left and right sides of the second beam 2, which can increase the strength of the second beam 2 and reduce the deformation of the beam.
[0032] See Figure 1 As shown, in some embodiments, a limiting groove 26 is provided at the lower outer side of the second beam 2. The limiting groove 26 extends along the length direction of the second beam 2. A base is provided below the longitudinal beam. A limiting post matching the limiting groove 26 is provided on the base. The limiting post is inserted into the limiting groove 26, which can limit the relative movement between the base and the longitudinal beam and ensure the stability of the longitudinal beam during operation.
