A spindle online indexing module of a numerically controlled wire cutting machine tool and its application method

Abstract

The invention relates to an on-line indexing module of a spindle of a numerically controlled wire cutting machine tool and a use method thereof. A fixed rail frame is installed on the base of the present invention, and a drive motor, a servo reducer, a lower driven roller bracket and a driving wheel bracket are installed on one side of the fixed rail frame, and a slider is arranged on the upper part of the fixed rail frame, and a slider is arranged on the upper part of the slider. There is a cross bar; the upper driven roller, the lower driven roller and the driving roller form a three-point clamping device, which fixes the workpiece in the X and Y directions. The driving motor drives the driving roller to rotate through the servo reducer and the transmission shaft, and the driving roller passes through the Friction with the workpiece drives the workpiece to rotate. The beneficial effects are: clamping with three rollers, convenient loading and unloading, adjustable distance between the rollers, which can meet the clamping of workpieces with different diameters; directly use the control signal of the machine tool itself, without increasing the control signal, without changing the programming method, and reducing the cost. Low, easy loading and unloading of workpieces.

Description

technical field [0001] The invention relates to a numerically controlled wire-cutting machine tool, in particular to a spindle online indexing module of a numerically controlled wire-cutting machine tool and a usage method. Background technique [0002] The CNC wire cutting machine tool is controlled by two axes. These two axes move in the X and Y directions, so it can only process simple shapes, and cannot process complex shapes such as spiral grooves. The traditional solution is to add a manual dividing head to the machine tool. However, it is still not possible to match the rotational movement of the spindle with the lateral movement on-line. Only simple circular array shapes can be processed. Another method is to add a rotational axis to the original X and Y axis movement, which needs to be added in the control system. Adding a control signal terminal increases difficulty and cost. Contents of the invention [0003] The purpose of the present invention is to aim at th...
