Description

Technical Field

[0001] The invention belongs to the technical field of front cover production equipment, and in particular relates to a horizontal beam guide rail vertical machining center. Background Art

[0002] A vertical machining center is a vertical machining center with the spindle axis set vertically to the machining table. It is mainly suitable for machining complex parts such as plates, discs, molds and small shells. The vertical machining center can complete milling, boring, drilling, tapping and cutting threads. The vertical machining center is at least three-axis two-linkage, and generally can achieve three-axis three-linkage. Some can perform five-axis and six-axis control. The column height of the vertical machining center is limited, and the processing range of box-type workpieces must be reduced. This is a disadvantage of the vertical machining center, but compared with the corresponding horizontal vertical machining center, it has a simple structure, a small footprint and a low price.

[0003] For vertical machining centers, the main structure generally includes a bed, a machine head, and a worktable. The bed includes a machine base, columns, and beams. The beam is installed on the machine base through the columns. The beam is an important component connecting the bed, the machine head, and the tool magazine. At present, the designs of the machine head structure by friendly companies are mainly upright hanging structure and drop structure.

[0004] Positive hanging structure: The beam linear rail is installed on the front of the beam, so that the machine head is hung on the front of the beam. This structure easily causes the machine head to tilt forward or backward, resulting in the verticality of the processing being affected, thereby reducing the processing accuracy. In addition, the processing rigidity of this structure is weak;

[0005] Drop structure: The two linear rails are installed on the inclined plane of the beam in a drop-tilt shape, which makes it difficult to level the two linear rails and easily causes asynchrony or jamming problems, further reducing the processing accuracy. This structure is more suitable for light cutting;

[0006] At the same time, the center of the machine head spindle is far away from the crossbeam, the structural rigidity is weak, the running stability is poor during high-speed processing, and there may even be shaking, which has a very adverse effect on precision processing.

[0007] In summary, the existing vertical machining center head structure has the problems of low machining accuracy and weak machining rigidity. At the same time, when the vertical machining center is working, the iron chips generated are easily accumulated on the bed, especially on the outside of the workbench. Since the workbench needs to be moved frequently during the machining process, if the iron chips are not cleaned in time, it will not only accelerate the wear of the workbench and reduce the service life of the workbench, but also affect the normal movement of the workbench due to the accumulation of iron chips, further reducing the machining efficiency. Summary of the invention

[0008] (1) Technical issues to be solved
