Automatic tool changing vertical machine tool and continuous machining method thereof

Abstract

The invention discloses an automatic tool changing vertical machine tool and a continuous machining method of the automatic tool changing vertical machine tool. The automatic tool changing vertical machine tool comprises a workbench, a slide saddle and a base, wherein the workbench, the slide saddle and the base are arranged from top to bottom in sequence. One side of the base is provided with a bracket arranging a main shaft to the workbench in an erecting manner, the bracket is provided with a fixing frame, the fixing frame is provided with a disc tool changer, and a tool changing device isarranged between the disc tool changer and the main shaft. The tool changing device comprises a tool changing drive motor and a lifting drive piece, wherein the tool changing drive motor is arranged on a tool changing rod and drives the tool changing rod to rotate, and the lifting drive piece drives the tool changing rod to move up and down. The middle of the tool changing rod is fixedly connectedwith the drive end of the lifting drive piece. The two ends of the tool changing rod are provided with C-shaped clamping slots for clamping tools, and the clamping slots are internally provided withjacking rods driven by clamping air cylinders. The automatic tool changing vertical machine tool is reasonable in structure, through the disc tool changer and the tool changing device, the automatic tool changing process of the vertical machine tool is realized, and the production efficiency of the machine tool is greatly improved; and through the clamping slots in the two ends of the tool changing rod, the tool at a tool changing opening and the tool in the main shaft are clamped rapidly, and the tool changing efficiency is improved.

Description

[0002] With the continuous development of society, the high-precision machining industry has entered a stage of rapid development. High-precision machining is widely used in high-speed rail, automobiles, shipbuilding, precision machinery, molds and other industries. High-precision machining is highly dependent on CNC machine tools. With the automation of CNC machine tools The level of requirements is constantly increasing, and the traditional operation method of manually replacing the tool is far from satisfying the current production mode. In the processing of high-hardness workpieces, it is necessary to process the workpiece for a long time, but the general tools of CNC machine tools are in The service life of machining high-hardness workpieces is relatively short, usually only 5-10 hours, which requires multiple tools to be replaced when machining a high-hardness workpiece. If it is still done manually, it will greatly affect the production efficiency of the machine tool , will also affect the machining accuracy
