Main shaft online indexing module of numerical control wire-cut machine tool and use method of main shaft online indexing module

Abstract

The invention relates to a main shaft online indexing module of a numerical control wire-cut machine tool and a use method of the main shaft online indexing module. A fixed guide rail bracket is installed on a base, a drive motor, a servo speed reducer, a lower driven idler wheel support and a driving idler wheel support are installed on one side of the fixed guide rail bracket, a slide block is installed on the upper portion of the fixed guide rail bracket, and a cross rod is arranged on the upper portion of the slide block. An upper driven idler wheel, a lower driven idler wheel and a driving idler wheel form a three-point clamping device to fix a workpiece in the X direction and the Y direction, the drive motor drives the driving idler wheel to rotate through the servo speed reducer and a transmission shaft, and the driving idler wheel drives the workpiece to rotate through friction between the driving idler wheel and the workpiece. The main shaft online indexing module has the advantages that clamping is achieved in the mode of the three idler wheels, assembly and disassembly are convenient, and the distances between the idler wheels are adjustable so that clamping of workpieces with different diameters can be met; control signals of the machine tool are directly used without adding other control signals and changing a programming mode, the cost is low, and the workpiece is convenient to assemble and disassemble.

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...
