Description

Technical Field

[0001] The utility model relates to the field of laser processing equipment, in particular to a laser cutting machine bed and a laser cutting machine. Background Art

[0002] Laser cutting is widely used in the processing and production of metal and non-metal materials due to its high cutting precision and fast cutting efficiency, which greatly improves the production efficiency and sample quality of manufacturers.

[0003] The bed of the laser cutting machine is the installation basis for the table components, axis motion system and laser head components of the laser cutting machine. It is the most important basic component of the laser cutting machine. Its quality and precision directly affect the movement accuracy of the laser head, and thus affect the processing accuracy.

[0004] The bed of most laser cutting machines is a beam structure, and the external covering plate is welded. At present, this structure is usually made by fitting the end face of the beam to the side of another beam, and then welding. Although the beam-column structure gives the bed a higher structural rigidity, it is difficult to accurately position the face-to-face connection during welding. Operators need to measure and mark in advance according to engineering drawings, which often leads to positioning errors in the corresponding key dimensions, and thermal deformation during welding, which causes some welds to deviate from the theoretical position, resulting in welding errors and large internal stresses after cooling. In summary, the current laser cutting machine bed welding operation procedures are extremely cumbersome, the production efficiency is low, the production cost is high, and the dimensional error is large. Summary of the invention

[0005] Aiming at the problem that the current laser cutting machine bed is difficult to position during welding and assembly, resulting in low bed precision and high internal stress, the utility model provides a laser cutting machine bed with mortise and tenon assembly.

[0006] In order to solve the above problems, the technical solution adopted by the utility model is a laser cutting machine bed, including multiple groups of relatively arranged columns, a crossbeam is arranged between the relatively arranged columns, the sides of the columns are provided with grooves, the two ends of the crossbeam are respectively embedded in the grooves of the corresponding columns, and the ends of the crossbeam are fixedly connected to the columns. The columns and the crossbeam are assembled and welded through the groove mortise and tenon structure, and the positioning function is formed by the groove, which reduces the positioning difficulty during the welding process, simplifies the operation process, and improves the positioning accuracy and assembly speed.

[0007] Preferably, in at least one group of oppositely arranged columns, the grooves are arranged on opposite surfaces between two columns.

[0008] Preferably, in at least one group of oppositely disposed upright posts, the grooves are disposed on coplanar side surfaces of two upright posts.

[0009] Preferably, the columns located on the same side together constitute a side elevation of the bed, in which:

[0010] Lower connecting beams are provided on opposite sides of adjacent columns, and both ends of the lower connecting beams are fixedly connected to the two columns respectively;

[0011] An upper connecting beam is commonly provided at the upper ends of adjacent columns, and two ends of the upper connecting beam are respectively fixedly connected to the upper end surfaces of the two columns.

[0012] Preferably, a reinforcing column is further provided between the upper connecting beam and the lower connecting beam, the upper end of the reinforcing column is fixedly connected to the bottom surface of the upper connecting beam, and the lower end of the reinforcing column is fixedly connected to the top surface of the lower connecting beam.

[0013] Preferably, intermediate connecting beams are provided between the reinforcing columns and the columns on both sides.

[0014] Preferably, in each side elevation of the bed, two reinforcement columns are provided, and the middle connecting beam is provided between the two reinforcement columns and the columns on the corresponding sides. The side elevation structure of the bed is formed by splicing the transverse and longitudinal beams, thereby improving the strength of the bed.

[0015] Preferably, a table top beam is provided between the cross beams, and the table top beam is located in a horizontal plane and perpendicular to the cross beams. The table top beam is provided to improve the firmness between the two cross beams and also serves as the installation basis of the table top structure on the bed.

[0016] Preferably, a base plate is installed on the lower end surface of the column, and a fixing hole is also opened on the lower part of the side surface of the column.

[0017] On the other hand, the utility model also provides a laser cutting machine, comprising the above-mentioned laser cutting machine bed. The laser cutting machine adopts the above-mentioned bed structure and has higher processing accuracy.

[0018] It can be seen from the above technical scheme that the advantage of the utility model is that the columns and beams of the bed structure are assembled and welded through the groove mortise and tenon structure, and the positioning effect is formed by the groove, which reduces the difficulty of positioning during welding, simplifies the operation process, improves the positioning accuracy and assembly speed, and at the same time, improves the morphological accuracy of the bed structure; furthermore, the laser cutting machine provided by the utility model can obtain higher processing accuracy.
