Floating cutter loosening device for central water discharging spindle

Abstract

The invention discloses a floating cutter loosening device for a central water discharging spindle. The floating cutter loosening device is characterized by comprising a gas-liquid cutter beating cylinder mechanism for providing cutter loosening power, a stroke adjusting mechanism for adjusting the stroke position of a cutter loosening point, and a floating cutter buckling mechanism for offsetting cutter loosening force acting on a spindle bearing; the gas-liquid cutter beating cylinder mechanism is arranged above and connected with the stroke adjusting mechanism; the stroke adjusting mechanism is arranged above a spindle cutter loosening disc; and the floating cutter buckling mechanism is sleeved on the upper end of the spindle bearing. The floating cutter loosening device for the central water discharging spindle has the advantages that the floating cutter buckling mechanism for offsetting the cutter loosening force acting on the spindle bearing is arranged, so the cutter loosening force does not directly act on the spindle bearing, the damage to the spindle bearing can be effectively avoided, the service life of the central water discharging spindle can be greatly prolonged, in addition, the controllability, reliability and production efficiency of the whole lathe can be improved, the automation degree of the lathe is ensured, and procedures such as subsequent mounting, debugging and maintaining are enabled to become simple and convenient.

Description

technical field [0001] The invention relates to a central water outlet spindle of a numerically controlled machine tool, in particular to a floating cutter release device for the center water outlet spindle. Background technique [0002] Since entering the 21st century, under the influence and promotion of the scale and industrialization process of automobile, shipbuilding, construction machinery and other industries, the cutting tool materials and processing technology of CNC machine tools have developed rapidly. When choosing processing technology schemes such as some deep hole parts or materials with high hardness, engineers tend to use the center water outlet spindle with internal cooling tools, which indirectly leads to the CNC machine tools with the spindle center water outlet function. market share is increasing. At the same time, due to the complex structure of the central water outlet spindle and the linkage of machinery, electricity, gas and hydraulics, its failur...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is: aiming at the deficiencies of the prior art, to provide a floating tool release device for the center water outlet spindle for the vertical CNC machining center, which can effectively solve the problem of the traditional center water outlet spindle Scratching of the transition sleeve causes the deformation or damage of the shell of the spindle rotary joint, resulting in failures caused by leakage of cutting coolant, and the problem of damage to the spindle bearing caused by the direct action of the spindle loosening force on the spindle bearing, with good controllability and reliability , which can greatly increase the service life of the central water outlet spindle
