Problems solved by technology

[0002] A CNC machine tool is an automatic machine tool equipped with a program control system, which can logically process the program specified by the control code or other symbolic instructions, decode it, express it in coded numbers, and input it into the CNC machine tool through the information carrier. After calculation and processing, the CNC device sends out various control signals to control the movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing. It is a flexible and high-efficiency automatic machine tool, which represents the development direction of modern machine tool control technology. It is a typical mechatronic product. When CNC machine tools are processing products, they usually use chucks Clamp the product to be processed, and the tool holder on the CNC machine tool is an important part for placing the tool, such as the square tool holder on the horizontal lathe, the turret tool holder on the turret lathe, and the return wheel of the rotary turret lathe Tool holders, turret tool holders and balance tool holders of automatic lathes, etc. Most of these are rotary tool holders, and only four tools can be installed. The inclined horizontal CNC machine tool can be equipped with eight tools, and because most of them are rotary The tool holder, which will cause the CNC machine tool to take up a large space, and often has a high center of gravity. Due to the structural relationship, it is not convenient to directly observe the specific processing conditions of the tool and the tool, and because the number of tool installations is small and the tool installation is complicated, it reduces the CNC machine tool. Therefore, the performance and structure of the tool holder often directly affect the cutting performance and cutting efficiency of the machine tool, and reflect the design and manufacturing technology level of the machine tool.

Abstract

The invention discloses an underneath alternating type knife rest numerical control lathe. The underneath alternating type knife rest numerical control lathe comprises a shell, a grasping mechanism, atail frame, a knife rest mechanism, a knife handle lifting mechanism and a knife rest transverse moving mechanism, the grasping mechanism is arranged on the shell, the tail frame is movably arrangedon two sliding base tables of the shell, the knife rest mechanism and the knife handle lifting mechanism are matched and movably arranged on the sliding base tables of the shell, and the knife rest transverse moving mechanism is in transmission connection with the knife handle lifting mechanism through a driving lead screw. The lower portion of a machine tool is fed from bottom to top, the gravitycenter of the machine tool is lowered, operation is stable, the length of the knife rest is shortened, tool vibration can be reduced, the machining precision and the rigidity of the machine tool areimproved, the contact condition of a tool and a workpiece can be visually and clearly observed, tool setting is convenient, and the machining progress is convenient to observe; and by arranging a toolmagazine, the number of replaceable tools is increased, the tool changing time is shortened, the machining efficiency is improved, installation and calibration of the cutters are simplified, use is more convenient and effective, and the machining time is saved.
