Summary of the invention
The purpose of this utility model is to provide a kind of milling machine spindle magnetic fluid vibration absorber, and the vibration kinetic energy of main shaft and cutter is transformed into magnetic fluid frictional heat energy by this device, then by heat exchanger, heat is taken away, thereby realizes the object of vibration damping, boosts productivity.
The purpose of this utility model is 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 transfer pump and magnetic fluid working bin 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, described magnetic fluid working bin holds heat exchanger outward.
Advantage of the present utility model 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, reaches effectiveness in vibration suppression, boosts productivity.
2. this device surrounds the heat exchanger of magnetic fluid working bin, heat-shift under the control of controller, the magnetic fluid that is about to enter magnetic fluid working bin absorbs the vibration kinetic energy of machine tool chief axis in cabin, the frictional heat energy being transformed between fluid powder is taken away, in order to avoid due to the uneven machine finish that affects of being heated.
Accompanying drawing explanation
Fig. 1 is the utility model device overall structure schematic diagram.
The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, the utility model is described in further detail.
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 shafts.
The utility model magnetic fluid working bin 1 and heat-exchange device 2 lock rings 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, finally send signal 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 rings 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 send signal by analyzer-controller 7, control transfer pump 5 via control circuit 6, control valve 4 and heat-exchange device 2.Accelerometer 8 detects vibration signal, by analyzer-controller 7 analytical calculation vibratory outputs, thereby 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 in storehouse, evokes the friction between magnetic fluid powder, and realizes dissipates vibration kinetic energy, reaches effectiveness in vibration suppression.Surround the heat exchanger 2 of magnetic fluid working bin 1, heat-shift under the control of analyzer-controller 7, the magnetic fluid that is about to enter magnetic fluid working bin absorbs the vibration kinetic energy of machine tool chief axis in cabin, friction between the fluid powder being transformed into and produce heat energy and take away rapidly, in order to avoid due to the uneven machine finish that affects of being heated.
