Abstract
Description
Technical Field
[0001] The invention relates to a numerically controlled lathe, in particular to an inverted numerically controlled lathe. Background Art
[0002] Inverted CNC lathes are widely favored by lathe processing industry because they are convenient for chip removal when processing inner holes; the spindle of conventional inverted CNC lathes is a vertical inverted structure, which not only affects the processing rigidity, but also is not conducive to the application of truss manipulators. In addition, with the tightening of land resources, the cost of processing sites is getting higher and higher, so it is hoped that the equipment can be more compact and miniaturized, so as to increase the volume ratio of the workshop and reduce management costs. Summary of the invention
[0003] The purpose of the invention is to provide an inverted vehicle with strong rigidity and compact structure.
[0004] In order to achieve the above-mentioned purpose of the invention, the present invention is mainly composed of a spindle unit, an X-axis CNC slide, a Z-axis CNC slide, a CNC turret tool holder and a machine body, and is characterized in that: the spindle unit is installed on the slide of the Z-axis CNC slide, and the rotation axis of the spindle unit is parallel to the guide rail of the Z-axis CNC slide; the Z-axis CNC slide is installed above the machine body and is tilted backward by 20 to 70 degrees relative to the operating surface; the X-axis CNC slide is installed below the Z-axis CNC slide and is perpendicular to the Z-axis CNC slide; a CNC turret tool holder is installed on the X-axis CNC slide, and the rotation axis of the CNC turret tool holder is parallel or perpendicular to the guide rail of the X-axis CNC slide.
[0005] As a further improvement of the above technical solution, the spindle unit, X-axis CNC slide, Z-axis CNC slide, and CNC turret tool holder are each divided into two groups; they share a machine body, and the Z-axis CNC slide and the X-axis CNC slide are arranged in an L shape; the two groups of spindle units, X-axis CNC slide, Z-axis CNC slide, and CNC turret tool holder are arranged in a mirror-like manner on the machine body, and the whole machine has an inverted T structure; this double-group structural mode is more conducive to the compactness of the structure.
[0006] The beneficial effects of the present invention are: 1. The Z-axis CNC slide on which the spindle unit is installed is tilted backward by 20 to 60 degrees relative to the operating surface, so that the center of gravity of the spindle unit and the Z-axis CNC slide can be better approached to the machine body, thereby improving the rigidity; 2. Both the X-axis CNC slide and the Z-axis CNC slide can be conveniently set to a structure that is not cantilevered relative to the slider, thereby better improving the rigidity; 3. The Z-axis CNC slide on which the spindle unit is installed is tilted backward by 20 to 60 degrees relative to the operating surface, which is also beneficial to the application of the truss manipulator in the machine, thereby greatly reducing the space in automatic loading and unloading applications; 4. The Z-axis CNC slide on which the spindle unit is installed is tilted backward by 20 to 60 degrees relative to the operating surface. This structure enables the machine tool to have the advantages of easy chip removal in inner hole processing of an inverted lathe, the high rigidity of a horizontal lathe, and the structure is also more compact.
