Technical Field

[0001] The utility model relates to the field of numerically controlled machine tool equipment, in particular to a numerically controlled vertical lathe. Background Art

[0002] CNC vertical lathes generally switch different tools by rotating the turret to process parts. After switching the tools, in order to avoid the turret descending and causing the part to come into contact with multiple tools, the turret needs to be translated as a whole to one side of the part before descending for processing. This results in a large horizontal position of the lathe equipment being occupied, which increases the space occupied by the equipment and is not conducive to cost savings. Utility Model Content

[0003] In view of the above problems, the utility model provides a CNC vertical lathe, which is applied to equipment that does not require rotating tools. A single tool that needs to be used can be lowered separately, saving equipment space and helping to save costs.

The limiting structure includes a limiting groove and a limiting block 34. The limiting groove is opened on the two opposite side walls in the mounting groove, and the limiting block 34 is arranged on both sides of the knife seat 32 corresponding to the limiting groove. The limiting block 34 is slidably connected to the limiting groove, and the return structure is a spring 35, which is vertically connected between the bottom side of the limiting block 34 and the side wall of the limiting groove; the first cylinder 40 is vertically arranged at the bottom of the slide 23 corresponding to one of the mounting grooves, and the motion trajectory of the end of the first cylinder 40 is staggered with the mounting groove, so that the end of the first cylinder 40 can extend into the mounting groove; the chuck 50 is rotatably arranged on the top of the base 10, and a motor for driving the chuck 50 to rotate is arranged in the base 10.
