Description

Technical Field

[0001] The utility model relates to the technical field of laser cutting, and in particular to a cutting machine crossbeam structure which is easy to adjust. Background Art

[0002] The application of laser cutting machines has developed rapidly in the domestic market in recent years, especially in the field of sheet metal cutting and processing. It has the advantages of high cutting accuracy, fast cutting speed, adaptability to various complex graphics, automatic typesetting, smooth incision, low processing cost, etc. It has replaced punching machines, flame cutting, plasma cutting and other equipment.

[0003] In order to improve the efficiency of laser cutting, many laser cutting machines are now equipped with laser cutting heads that can move quickly. Generally, a crossbeam is provided on a cutting machine. A laser cutting head is provided on the crossbeam. The crossbeam can slide along the machine bed. The laser cutting head can slide on the crossbeam, so that the laser cutting head can be displaced in two directions, thereby better cutting the plate. There are many designs for the crossbeam structure of the laser cutting machine. For example, the Chinese patent invention patent CN111098038A discloses a crossbeam and a laser cutting machine. The crossbeam includes a sliding part, an elastic connector and a main body. The sliding part is equipped with a first sliding mechanism, and the first sliding mechanism is slidably matched with the first bed. One end of the elastic connector is installed on the sliding part. The main body has a first end and a second end opposite to each other. The first end is connected to the other end of the elastic connector, and the second end is provided with a second sliding mechanism, and the second sliding mechanism is slidably matched with the second bed. In the above-mentioned crossbeam, since the elastic connector has a certain deformation capacity, the first end can be regarded as a sliding active end in the sliding of the crossbeam. When the first guide rail and the second guide rail are not parallel, the elastic connecting member can produce corresponding deformation according to the amount of non-parallelism, so as to compensate for the change in the distance between the first guide rail and the second guide rail, thereby avoiding pulling deformation or even damage between the first guide rail, the second guide rail and the crossbeam.

[0004] However, the above-mentioned laser cutting machine still has the following disadvantages: on a high-power laser cutting machine, the laser cutting head is heavy and moves fast, which makes the beam and the laser cutting head susceptible to motion loads and impacts during high-speed operation, causing deformation and affecting the accuracy. Moreover, after the high-power laser cutting machine has been used for a long time, the overall structure is heated, resulting in the verticality of the beam not being guaranteed, and the cutting stability is poor during the operation of the beam, and the accuracy is not guaranteed.

[0005] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable, efficient and adjustable cutting machine beam structure. Utility Model Content

[0032] As an embodiment of the utility model, the beam body 1 includes a beam body 11 and a mounting plate 12 arranged on the beam body 11 and extending toward the base 2.
