Description
The arbitrary distance of run length nano-stepping electromagnetic impact straight line of this project drives the fortune device and belongs to micro-stepping drive unit in the dynamo-electric field.
Along with development of modern industry needs, require precise treatment, miniaturization and the microminiaturization of plant equipment also more and more higher, as the accurate micro-stepping drive unit of microminiature equipment key technology, become the research focus in dynamo-electric field, the current world.Tokyo Univ Japan's electrostretch device that production technology research utilizes was developed into two-way micro-stepping drive unit (IDM) in 1991, this device has solved arbitrary distance of run in theory, micro-stepping drives, problems such as micro-structural, yet, under monolithic piezoelectric and the electrostriction wafer unit driving voltage, the output displacement is extremely limited, in order to obtain enough displacement output, in the practical application, the normal multi-disc thin slice that adopts builds up certain thickness through certain processing, piezoelectricity and electrostretch device through above-mentioned processing, draw, press the power output on the direction obviously inconsistent, in the IDM driving process, in fact device will bear and draw, press two kinds of percussions, and wherein direction micro-stepping motion is exactly when utilizing driving voltage sharply to descend, the former length of the fast quick-recovery of piezoelectricity and electrostretch device, cause the impact in opposite directions of coasting body and moving body, come the friction resistant step motion of this direction of implement device (being moving body), this impact obviously is limited, thereby has caused the bi-directional drive power and the two-way stepping accuracy of device inconsistent.Teaching and research room of China Guangdong Polytechnical College robot in 1994 adopt three independently piezoelectric ceramic be developed into biomimetic type stepping linear actuator (Inchworm), drive though this device has been realized big stroke and micro-stepping.But, because the piezoelectric ceramic maximum draws, presses power output inconsistent, when also having the device bi-directional drive, drive inconsistent problem, and structurally be difficult to microminiaturized and the more high deficiency of driving voltage.In addition, though voice coil motor and linear stepping motor etc. have also obtained many-sided application, the former stroke is too short, and the latter is difficult to obtain the length nano-stepping precision.
The purpose of this project is to develop tens millimeters levels of a kind of physical dimension, arbitrary distance of run, and its step pitch of bi-directional drive power and two-way stepping accuracy unanimity and speed are easily regulated manageable length nano-stepping electromagnetic impact formula drive unit.
The arbitrary distance of run length nano-stepping electromagnetic impact linear actuator of this project is made of impact block assembly, magnetic conductor, permanent magnet, pole, coil, return mechanism and ring washer.The operation principle of this driver is based on the impact gently of the object end face that is opposite on the plane, can realize the accurate fine motion location of object space is regulated.By to the current signal frequency in the coil, the change of amplitude, control and change the energy size that the impact block assembly impacts this device, realizing accurate step pitch control, and obtain enough actuating speeds.
Accompanying drawing 1 is the structural representation of arbitrary distance of run length nano-stepping electromagnetic impact linear actuator of the present invention.
This drive assembly adopts the symmetrical structure form, promptly by two permanent magnets (5) that pole (3) are housed, (12) be installed in two cup-shaped magnetic conductors (4) respectively, (11) centre position, interior chassis, be placed on again in the impact block assembly (13), make two pole (3) respectively be fixed on the impact block assembly in two return mechanisms (6) on the stalk with certain pretension contact and constitute a complete impact structure, distinguish coil (8) around the home at impact block assembly two, (10), on the impact block assembly between two coils, also be respectively arranged with adjustable two ring washers (2) in position, be used to limit and regulate the stroke of impact block assembly, magnetic shield tube (1) is sleeved on two cup-shaped magnetic conductors (4), (11) make whole device constitute an integral body on.Friction force adjustment mechanism (9) is passed to whole device by pressing plate (7), its objective is if use in the occasion that moves up and down, and certain frictional force is provided, and prevents that driver from falling automatically, and gathering sill (14) provides motion guide for the use of this driver.
The detailed operation principle and the process of this driver are, when the electric pulse control signal is flowed through when being in coil in the permanent-magnetic field, make coil produce electromagnetic force, the resistance that causes the impact block assembly to overcome return mechanism moves with certain acceleration, and draw and get ring washer magnetic conductor is impacted, thereby realize the friction resistant motion of driver on impact direction, stop up to this pulse signal ends motion.At this moment, the impact block assembly under the effect of return mechanism and reset, is waited for the arrival of next electric impulse signal again.Therefore, repeat above-mentioned control and motion, driver will drive the stroke that requires arbitrarily with certain stepping accuracy.Obviously, when coil passes to reverse electric pulse control signal, because the effect of permanent-magnetic field, in hot-wire coil, will produce reverse electromagnetic force, and the resistance that causes the impact block assembly to overcome return mechanism produces counter motion, and then draw the impact of getting corresponding ring washer and corresponding magnetic conductor, realize the reverse friction resistant motion of driver.
By the symmetrical structure of this driver and above-mentioned operation principle and process as can be known, this driver has not only been realized the requirement of arbitrary distance of run fully, and has realized the purpose of bi-directional drive power and two-way stepping accuracy unanimity.By above-mentioned operation principle also as can be known, the step pitch of this driver depends on impact energy (also regulating relevant with the pretension and the frictional force thereof of the mechanics condition that is driven part, quality, driver return mechanism certainly), and the speed of driver depends on impact energy and frequency of impact.Therefore, by regulating the amplitude and the frequency of electric pulse control signal, the step pitch of Control Driver and speed very easily.In addition, because the driver two coil configuration by suitable control, is very easily realized fast forwarding and fast rewinding, F.F. is moved back slowly, slow forward fast backward, and slow-motion is moved back slowly, the automatic selection and the control of promptly grand velocity stage or step pitch.
