Problems solved by technology

[0003] When using a single boring tool for cutting, it is easy to generate vibration due to uneven force, which will affect the machining accuracy of the taper hole of the rudder blade. In severe cases, the tool will be damaged and the service life of the tool will be shortened
Moreover, the axial movement of the boring tool is driven by mechanical transmission forms such as gears and screws. On the one hand, there are gaps between the gears and between the screw and the nut. These gaps are directly reflected in the movement a

Abstract

The invention discloses a multi-cutter NC boring lathe used for boring, comprising a plurality of support components, a self-aligning bearing component, a master drive component, a main shaft, a NC platform, a fixed sleeve and taper-boring mechanisms, wherein at least two taper-boring mechanisms are evenly distributed on the fixed sleeve; each taper-boring mechanism comprises a guide way, a stepper motor, a ball screw, a cutter holder and a cutting tool, wherein the ball screw comprises a driving screw and a ball base, the guide way axially fixed on the fixed sleeve along the main shaft and the separation angle between the guide way and the main shaft is an acute angle, the driving screw is pivoted on the guide way and is connected with the stepper motor, the stepper motor is arranged on the guide way and is electrically connected with the NC platform, the guide way is provided with a groove, the ball base is blocked in the groove of the guide way and is meshed with the driving screw, the cutter holder is fixed on the ball base, and the cutting tool is fixed on the cutter holder.

Description

technical field [0001] The invention relates to a boring processing machine tool, in particular to a multi-cutter boring processing numerical control boring machine used for tapered hole boring processing. Background technique [0002] At present, it is very difficult to process the taper hole of the rudder vane of a large ship, and the precision requirement is high, and the machining accuracy has become the focus and difficulty in ship processing. Traditionally, the processing form of the ship special rudder blade taper hole boring machine is to use mechanical transmission to drive the single guide rail boring tool to move, that is: the motor drives the large boring shaft to rotate, and then drives the gear set installed on the large boring shaft to rotate, and the gear set passes through The universal coupling transmits the power to the boring tool part installed on the large boring shaft and has a certain inclination relative to the large boring shaft. The screw in the bo...
