Background technology
Traditional electromagnetic spindles, are only the method that electromagnetism is replaced to conventional air-floating main shaft air floating properties as buoyancy, can
To break away from the device that source of the gas, filter, pressure-reducing valve etc. are cumbersome.The utility model be related to a kind of new electromagnetic spindles with it is conventional
Compared to not only being supported using magnetic buoyancy, adaptive adjustment magnetic force can also be utilized so that, can under different motion speed conditions
With adaptive dynamic balancing, process requirements are met, more particularly to one kind can be moved according to load is especially caused when processing workpiece
Uneven inertia income is eliminated, and reaches real dynamic balancing effect.
Utility model content
The purpose of this utility model is to overcome current defect to be based on adaptively adjusting dynamically balanced electromagnetism there is provided one kind
Main shaft.
The utility model uses multisection type magnetic float meter, and mover classification dynamic balance principle:
Multisection type magnetic float meter:Using modularization idea, because different rotating speeds lower main axis stress is different, traditional design
Maximum (top) speed lower stress is taken as design standard, the design uses multisection type magnetic float meter, i.e., in low speed only to two or
Multiple magnetic float unit power generation repulsion make main shaft mover suspend;At high speeds, all magnetic are floated with unit and is powered and ensure dynamic
Stability during son operation;This designs conventional design comparison, that is, reduce energy consumption has greater flexibility again.
Mover is classified dynamic balance principle:It is separated by a distance to reserve multiple balance mass blocks at mover longitudinal direction.Using turn
Fast sensor, micro-displacement capacitance sensor detection unbalancing value, it is removable inside drive shaft if detecting unbalance dynamic
Motor magnet dynamic balancing mass, is repelled each other by magnetic force and moved it, to realize the dynamically balanced process of dynamic regulation;
To achieve the above object, the technical scheme that the utility model is used is:
One kind is based on adaptively adjusting dynamically balanced electromagnetic spindles, it is characterised in that comprising motor stator 11, as the floating master of magnetic
When axle works, the electromagnetic spindles move main shaft by the repulsion produced between mover electromagnet 12, rotor powerful permanent magnetic iron 13
Son 14 suspends, and the mover electromagnet 12, the rotor powerful permanent magnetic iron 13 are collectively referred to as a magnetic and float unit;Main shaft is split
For the multiterminal of fixed intervals, every section of unit by this design is constituted;Different rotating speeds, main current supply circuit successively powers each section,
It is set to be suspended under different rotating speeds.
Further, generation repulsion of only being powered during low speed to the floating unit of two or more magnetic makes main shaft mover suspend;
Under fast state, all magnetic are floated with the stability that unit is powered when ensureing mover operation.
Further, electromagnetic spindles mover is uniformly and symmetrically distributed multiple dynamic balancing units;When detecting unbalance dynamic,
Will be electric on DM 23, the electromagnetic force of generation moves electromagnet dynamic balancing mass 22.
Further, the electromagnet dynamic balancing mass 22 itself has magnetic therefore can moved back and forth;Middle folder
Connected between plate and the electromagnet dynamic balancing mass 22 by moveable key, it is described when the upper electricity of the electromagnet 23
Key is unclamped, and the electromagnet dynamic balancing mass 22 can just be moved.
Further, dynamic equilibrium state is detected by tachometer of measuring, micro-displacement sensor.
Brief description of the drawings
Fig. 1 is magnetic float meter schematic diagram;
Fig. 2 is that mover is classified dynamic balance principle figure.
Embodiment
The purpose of this utility model is to overcome the shortcoming and deficiency of prior art dynamic based on processing self-adapting there is provided one kind
In the electromagnetic spindles of balanced adjustment, design with conventional electromagnetic spindles change very greatly, the utility model is embodied in using many
Segmentation magnetic float meter, and mover classification dynamic balance principle.
Multisection type magnetic float meter:First, the loop of main power supply is floated unit to multistage magnetic and powered, the sub- end-coil of multistage magnetic floating fixed
The electric constant magnetic force of generation is obtained, because 360 degree around main shaft mover, indexing is inlaid with magnetic after multiple-piece powerful permanent magnetic iron, energization and floated
The magnetic force that stator end-coil is produced produces repulsion with main shaft mover circumference last time powerful permanent magnetic iron so that Magnetic suspension spindle " floats
Come ".Only have two magnetic of head and the tail to float unit when not rotating or slowly running to power;When improving rotating speed, due to existing
The disturbing factors such as uneven inertia, flow perturbation, it is necessary to increase magnetic force, therefore, controller control the loop of main power supply gradual
Powered to other units, the need for meeting high rotating speed high capacity.
Mover is classified dynamic balance principle:
1) detect:Unbalance dynamic is only just showed when rotating speed is very high or reaches certain speed, when offline very
Hardly possible detection, so built-in speed probe is used to detect main shaft mover constantly rotating speed on main shaft at the beginning of design, it is equal on periphery
Cloth micro-displacement capacitance sensor, the unbalance dynamic inertia for detecting main shaft;
2) balance:Main shaft is moved adds paired removable motor magnet dynamic balancing mass in design, repels each other when being powered,
Balance mass block is moved to both sides, controls multigroup mass to move radial displacement to meet high-speed balancing requirement using voltage.
In order that those skilled in the art more fully understands the technical solution of the utility model, below in conjunction with the accompanying drawings and tool
