A kind of double end turning lathe and driving control system thereof
Technical field
The present invention relates to a kind of lathe, especially can realize synchronous a kind of double end turning lathe and the driving control system of processing with substep thereof of two workpiece.
Background technology
At present; Known lathe all is chucking work of a dynamical system control; In order to increase work efficiency and minimizing equipment takes up space in the working region; Also have two dynamical systems are combined on the chassis bed guide rail and carry out Design and Machining; The clamping times that can reduce workpiece like this with improve working (machining) efficiency, but minimize degree with the consumption of personnel's amount of labour from lathe design idealization and utilization of resources maximization and working (machining) efficiency maximization, traditional lathe and disclosed technology all do not have well will design and the utilization of resource and the factor of human and material resources effectively combine.
Such as: the applying date: 2002.04.26; Application number: 02231472.5; Title: double end numerically controlled lathe; Its principal character is that the other end at former lathe guide rail is provided with a geared head symmetrical with former geared head, and its design and use need realize the gradation clamping processing to workpiece with two cover power sources, though install the time of having practiced thrift at clamping; But adding the purpose that can not realize two workpiece synchronous processings man-hour, do not giving play to the maximum operating efficiency of two cover power sources to a certain extent.
Such as: the applying date: 2008.07.28; Application number: 2008201482285; Title: the middle double end numerically controlled lathe that drives, its design feature are that a power source drives in the middle intercropping of workpiece, make the two cover cutting systems on the both sides of workpiece carry out Compound Machining to the surface on workpiece both sides synchronously; The design of this both sides synchronous processing is confined to process the axial workpiece of respective specification; Nor can carry out Compound Machining to two workpiece synchronously, and can not realize still that in design the resource application is minimum, be worth the maximum effect of performance.
Such as the applying date: 2007.12.11, application number: 200720158288.0, title: double end numerical control woodworking lathe, it is characterized in that on the described dynamic component design two chucks up and down, corresponding with it also have up and down two knife rests and two tailstocks up and down; Its processing characteristic is two workpiece synchronous processings of clamping simultaneously, and its shortcoming is to carry out synchronous processing to different length and diameter and specification requirement different workpiece.
The design people has been directed against above Design and Machining defective and has designed in the patent No. of 2002.06.09 application is 02122581.8 " double end turning lathe and technology thereof "; But be primarily aimed at the processing of engine lathe and the design of expansion processing technology; Do not set forth the innovation and application of numerical control control technology synchronous and asynchronous processing on this double end turning lathe; There is not the uniqueness innovation in the detailed reflection geartrain systems yet; Or the like, the deficiency of using to above design, the present invention proposes new design.
