Many spindle bars automatic lathe is the machining equipment that last 100 years history is arranged, and has only one family of Shenyang Machine Tool Plant No.3 to produce in China.Produced first model machine from 1958 to existing nearly 50 years history beginning of this century.Protruding many spindle Lathe of the shaft type shortcoming of tradition is that precision is on the low side, processing parts cylindrical uniformity 0.05-0.1 millimeter is adjusted inconvenience, will change lobe plate, change gear etc. during renewal part, annex, attach more than half a year these annexes preparatory period, the lathe debugging generally also wants a week to two weeks.
Along with development of numerical control (NC) technology, produce the country of too much spindle bar lathe more abroad, carried out as Germany, Switzerland and developed many spindle bar numerical control lathes.
Many spindle bars frame numerically controlled lathe has very high precision and flexibility owing to replaced traditional cam drive with the numerical control servo axle, and the adjustment time of processing parts is shortened greatly.Lathe changes three fluted discs location into by former latch location.The uniformity of machine tooling cylindrical has been reached in the 0.01-0.02 millimeter.
Shortcomings such as but many spindle bar numerical control lathes still exist precision lower, and the lathe flexibility is low.
Summary of the invention:
The present invention is exactly at the problems referred to above, provides a kind of precision higher, the flexible high six-spindle bar numerical control lathe of lathe.
For achieving the above object, the present invention adopts following technical scheme, and the present invention adopts the high-grade digital control system of many processes parallel control; This lathe is controlled 17 linear servo axles altogether, the transposition of 6 rotating servo axles and lathe, feeding, the auxiliary movement that gets stuck; 6 cross-slides of lathe and 6 main carriages are that servomotor and ball-screw drive; Machine tool chief axis is a quill spindle, is the contact sealing; Three fluted discs of orientating as of machine tool chief axis drum body are located.
Beneficial effect of the present invention:
Compare with traditional mechanical cam formula multiple spindle lathe, six-spindle bar numerical control lathe of the present invention has three big advantages:
The first, high accuracy.Because numerical control multi-shaft changes three fluted discs location into by traditional multiaxis list latch location, positioning accuracy 0.01 by the past brings up to 0.003, and, knife rest changes the driving of servomotor ball-screw into because being driven by cam, the site error of 6 spindle Lathe can solve with the main shaft compensate function of digital control system, makes machining accuracy bring up to the 0.01-0.02 millimeter by the 0.05-0.1 millimeter of traditional multiaxis.
Second advantage is the flexibility that has improved lathe.Past, traditional multiple spindle lathe just changed processing parts, need to make a large amount of attach as lobe plate, form tool, tapping, car silk etc.Attach the annex manufacturing cycle all more than half a year, lathe changes batch debug time also about two weeks, and the numerical control multi-shaft lathe does not need to change lobe plate and change gear., change batch debugging and only need change the feeding and gripping material chuck and change procedure and get final product because but the external surface of any curve of servo compound slide two coordinate interpolation turning does not need specialized designs to make molding cutter.And procedure can be finished in advance in office, has time half a day to finish and changes batch debugging.
The 3rd advantage, because the high flexibility and the numerical controlization of lathe have been widened application, the past only is fit to the multiaxis automatic machine of production in enormous quantities.The numerical control multi-shaft lathe more can adapt to the processing of small batch part.Because the raising of numerical control of machine toolsization and machining accuracy more can adapt to the part processing of IT industry, also more can adapt to the computer and the management of modern enterprise.
Six-spindle bar numerical control lathe is that the collection contemporary advanced is the world-class machining equipment of one, it is inheriting tradition mechanical cam formula multiaxis advantage efficiently, overcome shortcomings such as its flexible difference, the multispindle automatic machine of new generation that updates will play an increasingly important role in modern manufacturing industry.
