Description
Technical field
The present invention relates to a kind of lathe damping device, particularly relate to a kind of milling machine spindle magnetic fluid vibration absorber.
Background technology
Lathe forward high speed, high accuracy and high efficiency future development, can produce flutter during high-speed cutting, affects machining accuracy and quality, inevitably reduce productivity ratio, can not give full play to the working ability of lathe.High-speed machining milling machine causes spindle vibration to produce flutter due to the periodicity of process and the periodicity of cutting force, affects crudy.
Summary of the invention
The object of the present invention is to provide a kind of milling machine spindle magnetic fluid vibration absorber, the vibration kinetic energy of main shaft and cutter is become magnetic fluid frictional heat energy by this device, then is taken away by heat by heat exchanger, thus realizes the object of vibration damping, boosts productivity.
The object of the invention is to be achieved through the following technical solutions:
Milling machine spindle magnetic fluid vibration absorber, described device comprises magnetic fluid working bin, heat-exchange device, control valve, magnetic fluid storing box, transfer pump, control circuit, analyzer-controller, accelerometer, main shaft; Magnetic fluid working bin and heat-exchange device lock ring are on machine tool chief axis, control valve is connected with magnetic fluid working bin with transfer pump respectively, the lower end connection of transfer pump is equiped with magnetic fluid storing box, accelerometer is connected on the connected cutter in main shaft one end, and analyzer-controller connects transfer pump and magnetic fluid working bin via control circuit.
Described milling machine spindle magnetic fluid vibration absorber, holds heat exchanger outside described magnetic fluid working bin.
Advantage of the present invention and effect are:
1. this device fluid enters the magnetic fluid of magnetic fluid working bin, absorbs the vibration kinetic energy of machine tool chief axis in cabin, both vibration energy utilized magnetic fluid is transformed into the friction between fluid powder, and dissipates vibration kinetic energy, and reached effectiveness in vibration suppression, boost productivity.
2. this device surrounds the heat exchanger of magnetic fluid working bin, heat-shift under the control of the controller, the magnetic fluid being about to enter magnetic fluid working bin absorbs the vibration kinetic energy of machine tool chief axis in cabin, the frictional heat energy be transformed between fluid powder is taken away, in order to avoid uneven affect machine finish owing to being heated.
Accompanying drawing explanation
Fig. 1 is apparatus of the present invention overall structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing illustrated embodiment, the invention will be further described.
In figure, parts are: 1. magnetic fluid working bin 2. heat-exchange device 3. control valve 4. magnetic fluid storing box 5. transfer pump 6. control circuit 7. analyzer-controller 8. accelerometer 9. main shaft.
Magnetic fluid working bin 1 of the present invention and heat-exchange device 2 lock ring are on machine tool chief axis, control valve 3 and transfer pump 5 provide appropriate magnetic fluid to enter magnetic fluid working bin 1, accelerometer 8 detects vibration cutting signal, signal is sent finally by analyzer-controller 7, control kinetic pump 5, control valve 3 and heat exchanger 2.Magnetic fluid working bin 1 and heat-exchange device 2 lock ring are on machine tool chief axis 9, control valve 3 and transfer pump 4 provide appropriate magnetic fluid to enter magnetic fluid working bin 1, accelerometer 8 detects vibration cutting signal, then signal is sent by analyzer-controller 7, transfer pump 5 is controlled, control valve 4 and heat-exchange device 2 via control circuit 6.Accelerometer 8 detects vibration signal, by analyzer-controller 7 analytical calculation vibratory output, thus by control valve 3 and transfer pump 5, controls magnetic fluid and enters magnetic fluid working bin 1.Magnetic fluid working bin 1 lock ring, on main shaft, enters the magnetic fluid of magnetic fluid working bin 1, absorbs the vibration kinetic energy of machine tool chief axis, evoke the friction between magnetic fluid powder, and realize dissipates vibration kinetic energy, reach effectiveness in vibration suppression in storehouse.Surround the heat exchanger 2 of magnetic fluid working bin 1, heat-shift under the control of analyzer-controller 7, the magnetic fluid being about to enter magnetic fluid working bin absorbs the vibration kinetic energy of machine tool chief axis in cabin, friction between the fluid powder be transformed into and produce heat energy and take away rapidly, in order to avoid unevenly affect machine finish owing to being heated.
