Description

Become the electric spark revolution generate processing unit (plant) of helical angle gear by tooth
Technical field
The utility model relates to a kind of gear machining equipment; Specifically relate to become the processing unit (plant) of helical angle gear by tooth.
Background technology
Becoming the helical angle gear by tooth is a kind of very special gear, and it is with helical gear maximum difference commonly used at present: the helical angle of each tooth is identical on the common helical gear, and all is different by the helical angle of each tooth on the tooth change helical angle gear.Though plant through very ripe about helical gear processing technology at present, see about the patent of the electric spark generate processing aspect of the machining of helical angle gear and gear is quite a few, as application number be 88102455, the applying date is that April 26, denomination of invention in 1988 are the patent application of method for precessing bevel gear with big helical angle at milling machine, it is to change milling cutter above workpiece, method by the moving helical angle of vertical working plate, pull workpiece helical angle in the side of working by end mill head and change milling cutter into, can process helical gear at any angle thereby reach.And for example application number is 95112710, the applying date is that September 28 nineteen ninety-five, denomination of invention are the patent application of the electric spark staggered expansion machining method of fine-pitch of involute gear, its technological process is: it is the tooth bar electrode of the electric spark staggered generate processing of (1) design usefulness, comprise and determine staggered generate ratio, calculate the electrode profile of tooth, its concrete steps are: (a) calculate and be equivalent to the profile of tooth 1 of transmission with tooth bar; (b) calculating is equivalent to the profile of tooth 2 of machining with rack cutter; (c) calculate the profile of tooth 3 of general electric spark generate processing with the tooth bar electrode; (d) calculate the profile of tooth 4 of electric spark staggered generate processing with the tooth bar electrode; (2) use quick wire wire cutting technology to make the tooth bar electrode; (3) machining gear blank; (4) on the numerical control electric spark forming machine, finish the installation and the centering of electrode and workpiece; (5) establishment numerical control electric spark shaping procedure comprises and selecting and the change electrical guiding rule, specifies each motion mode, finishes the shaping of involute fine module gear with the discharge ablation.But the above-mentioned method and apparatus that adds work gear all can only be processed the identical helical gear of each tooth helical angle, or the difficult problem of solution fine module gear processing, they all can't process the mutually different gear of each tooth helical angle, still find no by retrieval to close the bibliographical information that becomes the helical angle gear machining equipment by tooth.The at present domestic device that does not still have the different gear of each tooth helical angle of processing, thereby commercially available this kind gear is generally all from external import.
Summary of the invention
The purpose of this utility model is to provide a kind of device that utilizes electric spark revolution generate processing mode processing the change by tooth helical angle gear.
The utility model is realized above-mentioned purpose by following proposal: should comprise a swing span by the electric spark revolution generate processing unit (plant) of tooth change helical angle gear, feed mechanism and machining control circuit, swing span is provided with motor and by the rotating shaft of driven by motor, processing work is fixed in this rotating shaft, the top of workpiece is provided with an electrode, electrode is fixed in the rotating shaft by a driven by motor, above-mentioned two rotating shafts all connect the pulse power, the rear end of swing span links to each other with the rotating shaft of a motor, swing span is connected with the feed mechanism that promotes by motor simultaneously, and above-mentioned motor all is electrically connected with control circuit by circuit.
The utility model has adopted the motor that links to each other with swing span by control circuit control to realize controlling angle between workpiece rotating shaft and the electrode rotating shaft, has adopted motor and the electrode rotating shaft driving motor of controlling workpiece rotating shaft transmission by circuit to realize that motor gear and workpiece add the identical gearratio of work gear; Motor by control circuit control feed mechanism is realized the amount of feeding that workpiece is processed, thereby realize becoming the Gear Processing of helical angle gear by tooth, adopt the device of said structure can pass through the gear of the mode of programming by the different helical angle Changing Patterns of control circuit realization processing, cost greatly reduces, processing is simple simultaneously, can be completely achieved production domesticization, thereby can change the present situation of domestic said gear dependence on import, have market prospects preferably; Add man-hour, this device can be controlled the gear motion that workpiece and electrode are simulated processed gear and gear electrode, and realizes processing by the spark discharge between workpiece and the electrode.
Description of drawings
The utility model is described in further detail below in conjunction with the drawings and specific embodiments
Fig. 1 is the utility model structural representation.
Specific embodiment
As shown in Figure 1, electric spark revolution generate processing unit (plant) by tooth change helical angle gear of the present utility model comprises a swing span 9, feed mechanism 13 and machining control circuit 12, the rotating shaft 8 that swing span 9 is provided with motor 2 and is driven by motor 2, processing work 6 is fixed in this rotating shaft 8, the top of workpiece 6 is provided with the used electrode 5 of a processing, this processing electrode used therein 5 adopts spur gear, electrode 5 is fixed in the rotating shaft 7 that is driven by a motor 1, above-mentioned two rotating shafts 7,8 all connect the pulse power 11, the rear end of swing span 9 is connected with a motor 3 by shaft joint 10, swing span 9 is connected with the feed mechanism 13 that promotes by motor 4 simultaneously, and above-mentioned motor all is electrically connected with control circuit 12 by circuit.
The course of work of the present utility model is: adopt the ordinary straight gear as processing used tool electrode, machining control circuit 12 is by the movement velocity control to motor 1 and motor 2, the rotating ratio of workpiece 6 and electrode 5 is accurately equated with the gearratio of processed gear with the electrode gear, and machining control circuit 12 changes with the helical angle that realizes processed each tooth of gear simultaneously also by the angle between motor 3 drive swing spans, 9 control workpiece rotating shafts 8 and the electrode rotating shaft 7.Motor 4 drives feed mechanism 13 and moves in the process under the control of machining control circuit 12, drive workpiece 6 progressively near electrode 5, when the distance between workpiece 6 and the electrode 5 during less than a certain gap, the pulse power 11 produces spark discharge by the gap between workpiece 6 and the electrode 5, the material ablation of correspondence position on the workpiece 6 is fallen, along with continuous feeding, workpiece becomes the helical angle gear constantly by ablation until the tooth that pursues that processes requirement.
