Abstract
The invention provides a machine tool capable of cutting an inner bore keyway of a workpiece without threading a wire electrode repeatedly, which comprises a thread storage barrel 1, the wire electrode 2, an upper fixed guide wheel 3, an upper guide wheel 4, a lower fixed guide wheel 5, the workpiece 6, a work platform 7, a guide wheel support 8, an engine base 9 and the like. The wire electrode 2 is led out from one end of the thread storage barrel 1, passes through the upper fixed guide wheel 3 and the inner hole of the workpiece 6, returns to the inner hole of the work piece again after being guided by the upper guide wheel 4, returns to the other end of the thread storage barrel through the lower fixed wheel 5 after being led out through the inner hole of the workpiece; and the upper guide wheel is arranged on the guide wheel support 8 one end of which can pass through the inner hole of the workpiece. By adopting the guide wheel support and the mode of threading the wire electrode, the workpiece can be put in or taken out of a station without threading the wire electrode repeatedly, and volume production of the same workpiece can save time and improve production efficiency.
Description
Technical field: the invention belongs to line cutting processing and wire cutting machine tool manufacturing industry
Background technology: in the present online cutting processing manufacturing industry, think the keyway of cut workpiece endoporus, connect wire electrode again.Connect in the operating process of wire electrode, hand is had to and is the wire electrode of greasy dirt everywhere, silk tube, contacts such as guide wheel.So it is not only time-consuming but also very dirty to connect wire electrode.Therefore the working (machining) efficiency of inner hole key slot is more much lower than processing profile efficient.
Summary of the invention: the invention provides a kind of method and lathe that need not repeat to connect wire electrode just can the cut workpiece inner hole key slot.
Description of drawings: accompanying drawing 1 is example 1 an inventive principle schematic diagram
Accompanying drawing 2 is example 2 inventive principle schematic diagrames
The specific embodiment:
Example 1: as accompanying drawing 1; Stator ring on 1 wire storage cylinder, 2 wire electrodes, 3,4 upper guide wheels, 5 times stator rings, 6 workpiece, 7 workbench, 8 guide wheel bracing frames, 9 supports.
After wire electrode 2 is drawn via last stator ring 3 from an end of wire storage cylinder 1, pass the endoporus of workpiece 6 again, the other end at the workpiece endoporus, through returning once more into the workpiece endoporus after upper guide wheel 4 guiding, get back to the other end of wire storage cylinder 1 after being drawn by the workpiece endoporus again through stator ring 5 down, described upper guide wheel 4 is mounted on the guide wheel bracing frame 8 that one one end can pass the workpiece endoporus.Owing to adopted described guide wheel bracing frame 8 and the described mode that connects wire electrode, so station be put into or be taken out to workpiece 6 can need not repeating to connect under the situation of wire electrode.Upper guide wheel 4 reaches down, and the wire electrode between the stator ring 5 is an effective machining area, pass through control system, the relative motion of control workpiece and wire electrode is just can finish interior contour shape and size such as keyway, spline or the involute spline wanting to process, reach internal gear etc.
Example 2: as accompanying drawing 2; Stator ring on 1 wire storage cylinder, 2 wire electrodes, 3,4 upper guide wheels, 5 times stator rings, 6 workpiece, 7 workbench, 8 guide wheel bracing frames, 9 supports.
With the difference of example 1 be that upper guide wheel 4 has adopted two guide wheels, wire electrode between one of them guide wheel and the last stator ring 3, be effective machining area, wire electrode between another guide wheel and the following stator ring 5, be effective machining area, so just formed two effective machining areas, pass through control system, the relative motion of control workpiece and wire electrode just can be finished and want the shape and the size of processing.
Adopt said method to produce same workpiece in batches, so owing to need not repeat to connect wire electrode and can save time and enhance productivity.
