Description
Technical field
The utility model relates to to-and-fro thread feed electric spark line cutting processing technical field, and particularly a kind of electric spark linear cutting machine prevents the device that wire electrode comes off in wearing a process.
Background technology
To-and-fro thread feed electric spark line cutting processing technology is to utilize the wire electrode that moves as tool-electrode, and between wire electrode and workpiece, passes to pulse current, utilizes the high temperature of pulsed discharge moment generation to come the corrode workpiece to remove the processing method of material.What electric spark linear cutting machine adopted is exactly that to-and-fro thread feed electric spark line cutting processing technology is come processing work; It is after the V-type groove of guide wheel is walked around in the artificial traction of the wire electrode on wire storage cylinder; Compress drawing back wire storage cylinder; Wire storage cylinder carries out forward and reverse rotation under the control of travel switch, associated mechanisms and electric appliance circuits, thereby realizes the reciprocating motion of wire electrode in the processing district.Before the spark coil cutting processor bed is processed workpiece; Wear a technology and be about to wire electrode to walk around the V-type groove of guide wheel be a very important processing step, because the V-type groove depth of guide wheel is more shallow, wire electrode is easy to come off from guide wheel in wearing a process; And in a wire cutting machine tool quantity of guide wheel often more than 3; Even nearly 8,9, it is bigger therefore to wear a difficulty, usually is to have put on a guide wheel; The wire electrode of a last guide wheel has come off again, has wasted the production time of lathe greatly.
The utility model content
The purpose of the utility model just is the deficiency to prior art, provides a kind of electric spark linear cutting machine that prevents that in wearing a process wire electrode from coming off to use the wire electrode anti-drop device.
To achieve these goals, the technical scheme of the utility model employing is such: a kind of electric spark linear cutting machine is used the wire electrode anti-drop device, comprises wheel stand, guide wheel; Guide wheel is fixed on the wheel stand, it is characterized in that: also comprise little axle, spring and anticreep pawl, little axle one end is provided with boss; Little axle passes the anticreep pawl and is slidingly mounted in the endoporus on the wheel stand; Little shaft end is provided with nut, is with spring on the little axle between wheel stand and the anticreep pawl, and the anticreep pawl is over against the V-type groove of guide wheel.
Further improvement as the utility model; Described a kind of electric spark linear cutting machine also comprises guide wheel protection seat ring, anticreep pad and protection outer shroud with the wire electrode anti-drop device; Guide wheel passes guide wheel protection seat ring and is fixed on the wheel stand; The protection outer shroud is fixed on outside the guide wheel protection seat ring; Protection outer shroud and guide wheel protection seat ring center fixed have the anticreep pad, and the width of anticreep pad is identical with the width of guide wheel V-type groove, and the edge of guide wheel protection seat ring and protection outer shroud contacts with the one side of anticreep pawl over against guide wheel V-type groove.Because outside guide wheel V-type groove, set up guide wheel protection seat ring and protection outer shroud, the guide wheel of anticreep pawl and rotation produces friction when avoiding work, the adding of anticreep pad has strengthened wears a space, make wear thread more simple.
When using the utility model to wear thread; Earlier press little axle with have gentle hands, the anticreep pawl is along with open in the slit that guide wheel is protected between seat ring and the protection outer shroud of moving of little axle, with wire electrode hang into; Unclamp little axle then; The anticreep pawl receives the screen resilience effect of spring and gets back to original position, the slit between sealing guide wheel protection seat ring and the protection outer shroud, and wire electrode can not come off out.Because the width of anticreep pad equals the width of guide wheel V-type groove, therefore if wire electrode hang from the slit between guide wheel protection seat ring and the protection outer shroud into, wire electrode is certain to hang in the V-type groove of guide wheel.The utility model has well solved the problem that comes off of electric spark linear cutting machine wire electrode in wearing a process, has practiced thrift greatly and has worn a time, has improved the production efficiency and the operating characteristics of lathe.

The specific embodiment
For purpose, technical scheme and the beneficial effect of more clearly understanding the utility model, will combine accompanying drawing and practical implementation that the utility model is described further below, but the protection domain of the utility model will not be limited in following examples.
Referring to Fig. 1, Fig. 2, Fig. 3; A kind of electric spark linear cutting machine of the utility model is used the wire electrode anti-drop device, comprises wheel stand 1, guide wheel 2, spring 5, anticreep pawl 6, guide wheel protection seat ring 3, anticreep pad 4, protection outer shroud 7 and little axle 8, and guide wheel protection seat ring 3 is fixed on the wheel stand 1; Guide wheel 2 passes guide wheel protection seat ring 3 and is installed on the wheel stand 1; Protection outer shroud 7 is fixed on outside the guide wheel protection seat ring 3, and protection outer shroud 7 has anticreep pad 4 with guide wheel protection seat ring 3 center fixed, and the width of anticreep pad 4 is identical with the width of guide wheel V-type groove 9; Little axle 8 one ends are provided with boss 11; Little axle 8 passes anticreep pawl 6 and is slidingly mounted in the endoporus on the wheel stand 1, and little axle 8 ends are provided with nut 10, is with spring 5 on the little axle 8 between wheel stand 1 and the anticreep pawl 6; Anticreep pawl 6 is over against the V-type groove 9 of guide wheel, and the edge of guide wheel protection seat ring 3 and protection outer shroud 7 closely contacts with the one side of anticreep pawl over against guide wheel V-type groove.
Because guide wheel V-type groove 9 outside, set up guide wheel protection seat ring 3 and protection outer shroud 7, the guide wheel of anticreep pawl and rotation produces friction when avoiding work, the adding of anticreep pad 4 has strengthened wears a space, feasible wear thread more simple.
When wearing thread; Earlier press little axle 8 with have gentle hands, anticreep pawl 6 is along with open in the slit that guide wheel is protected between seat ring 3 and the protection outer shroud 7 of moving of little axle 8, with wire electrode hang into; Unclamp little axle 8 then; Anticreep pawl 6 receives the screen resilience effect of spring 5 and gets back to original position, the slit between sealing guide wheel protection seat ring 3 and the protection outer shroud 7, and wire electrode can not come off out.Because the width of anticreep pad equals the width of guide wheel V-type groove, therefore if wire electrode hang from the slit between guide wheel protection seat ring and the protection outer shroud into, wire electrode is certain to hang in the V-type groove of guide wheel.The utility model has well solved the problem that comes off of electric spark linear cutting machine wire electrode in wearing a process, has practiced thrift greatly and has worn a time, has improved the production efficiency and the operating characteristics of lathe.
