Description
MICRO DISPLACEMENT MECHANISM AND METHOD OF
MACHINE DEFORMATION & TRANSDUCER DEFORMATION QUANTITY
CONTROLLED BY ELECTRICAL SOURCE OR MAGNETIC ENERGY
In the earliest epoche of the human, the required precision was 10 mm which could be achieved by the human hands and eyes; when the vehicles had been invented the human required the achse and dismeter in 1 mm precision.
At that time, the skillful man adjusted the position on the solid machine with a machining cutter; when the vapor ermine had been invented, the human required 0.05 mm working displacement unit for working the pistons and the cavity hole; when the guns and the inner combustion engine with high pressure had been invented, the human required 0.01 mm working unit; At the present, we need 0.001 mm (lout) for adjusting the crystal piece of micro electron and the cell position which will be treated in the biological technolog; and for adjusting the position of the detecting head in the optical laser measuring distance. In this epoche, the dynamic adjusting elements made of the precision threads play an important role.But it is not enough for the micro adjustment with more precision. The reasons are as follows:
(1) The thread is a slopy movement. But the present technolo#- is not yet to make a line with the error under O.9Olmr..
(2) The volume will be increased.
(3) It needs high cost.
(4) Because the static friction can be not equal to dynamic friction, it is not easy to make an adjustment. For the micro drive, the frequency response is also too low.
(5) When there is extra micro position driftage of the temperature deformation after the adjustment, it is difficult to make micro recoxrery supplemental structure and the hunting phenomenon will be generated.
Eased on the said defects, the present invention provides a micro displacement mechanism and method of the machine deformation and transducer deformation quantity controlled by the electrical source or magnetic energy As shown in Fig. 1, it is composed of an orienting aim 101 (i.g. the detecting head of the precision measuring equipment), moving body 102, transducer 103, sliding base seat 104, static body with slide track 105, rough positioned driving element 106, locking equipment 107, precision measuring equipment 108 and adjustable electrical source & magnetic energetic source used for controlling the transducer 109, in which:
- The precision measuring equipments 108 have been de#e1oped, such as::
laser measuring instrument;
optical interference measuring equipments.
The moving body 102 and the orienting aim 108 depending
upon the applicable equipment, for example:
a measuring head of a measuring instrument;
an injection needle of the cell;
an optical lens;
a transfer head of laser;
a machining cutter;
an optical reflex reflector;
or other precision micro displacement equipment.
- The transducer 103 is used for transfering the input magnetic energy into the machine deformation displacement, for
example, elastic element of magnetic h=steresis, such as
NiAF alloy, ferrite, or for transfering the input electrical energ,- into the machine deformation displacement, for example,
the deformation element of electrical field, such as titanite
barium, titanite lead, or the piezoelectric elements, such
as quartz, Rochelle-salt, ADP.They are installed (pasted
or locked or soldered or casted) between the moving body
and the sliding base seat, in which the relative deformation
quantity will be generated by means of the size adjustment
of the outer actuating electric or magnetic energn-, and
the angle between the deformation orientation and the orienting aim is Oc or within 900 for generating the
deformation displacement moving toward the orienting aim.
The aliding base seat 104 is coupled with the static body
by way of the guide track or other sliding coupling method,
and can be driven by the precision positioned driving equipment 106, such as guide screw and nut set or precision
gear or manual force, and has the positioning lock equipment
107 for locking after the rough positioning.
The actuating electrical source or magnetic energetic source 109 for controlling the deformation quantity of the transducer
has the following deformation quantities depending upon the
properties of the transducers:
1. The deformation quantity of piezoelectric or electrical
field type transducer by way of the electrical source
with adjustable voltage.
2. The deformation quantity of magnetic hysteresis elastic t-pe transducer operated by the magnetic field strength
of the coils or permanent magnet magnetinized by the
adjustable current source.
The applicable technique required for the said design can cite the connecting method of the transducer and its base seat in the ultrasonic working technique. Its biggest difference is that its driving electrical source, but the deformation value of the transducer is changed by the adjustment of the voltage or coil current value or magnetic field strength. It is different from the method, in which the various effects are generated by the vibration of the transducer by means of AC voltage or electric current source in the applicable ultrasonic equipment.
In the practical application, the said design contains single coordinate axes, double coordinate axes and three coordinate axes. Its various applicable examples are as follows: (A) When the design of the singlecoordinate axes are used in
the ultrasonic machine working, the micro cutter-feeding
adjustment can be added in the working. Its methods
certain:
(1) As shown in Fig. 2, the DC current level of load wave
DC actuating electrical source 201 used for driving
the transducer can be adjusted. (Depending upon the
kind of the transducer, the voltage or electrical
source can be adjusted).Using the change of electrical field or the magnetinizing field generated by t#.-- Id adjustment, the said displacement value can be adjused
by the said DC current level; But the DC deformation
adjusting value should be reserved for the adjustment
in the said load wave deformation value, i.e, load
wave deformation value plus wax. Adjusting DC defor
mation value should be less than satuiation deformattion
value of the transducer.
(2) The micro adjustment should be added in the working, and
the amplitudes are changed by the adjusted input voltage
voltage or magnetizing coil current value or magnetic
field strength and then the cutter-feeding quantity is
further changed. The said method is used in the working
with non-sensitive amplitude.
(3) Using two sets series transducers, in which a set 302 is
used for generating ultrasonic vihrating deformation
and another set 301 is used for generating the adjusting
deformation displacement. The said method has two sets
electrical sources: one set 304 is used fordriving the
ultrasonic transducer and another set 303 can be an
adjustable electrical source or magnetic source and is
used for adjusting the deformation displacement quantity
of the transducer used for generating the ultrasonic
wave in order to make micro displacement (a- s-loçn in Fig.3).
(4) When the said design is used for the measuring instrument, its applications contain: 1. Micro displacement of the position,i.e. the said
adjusted voltage or electrical source used for
generating the deformation displacement of the
transducer; 2. Micro amendment of the position, i.e. when the rough
position has been adjusted and locked, the rough
adjusted size can be amended by the change of the
deformation value of the said transducer by way of
adjustment of the said adjustable electrical source
or magnetic field source.
3. The drive used forthe micro compensation of the
position error. Because the manufacture of the
linear measuring equipment has the micro linear
errors which will be accumulated, the structure of
the said method, as shown in Fig. 4, contains:
- The moving body is a detecting head 401 used for
installing the optical or electromagnetic or laser
measurement;
- The transducer eet 403 is installed between the
measuring rule 402 and the main body.Its defor
mation direction can be co-axial with the driving
direction of the moving body or mess than 900, so
that it can transfer the electric energy to the
transducer driving electrical source 405 by means
of preseted error value memory equipment 404 for
changing its elastic value and then for amending
the linear error of the measuring rule;
- Measuring value processor 406 including the corredive
amended display based on the comparison of the counting
circuit of signal counting read by the measuring
detecting head with the value in the error value memor- equipment 404 for setting the reference error,
The features of this method are quick compensation
response, no dynamic element, low cost and less trouble.
(5) Adjustable focal distance used in the optical instruments;
As shown in Fig. 5, it is an applicable example of the
cutting of the Laser, in which ring-shaped trasducer 501
is installed an the middle section of the adjustable knob
502, and the deformation direction of the said transducer
501 is the same as the adjusted axial direction or within
900. Therefore, the micro focal distance can be adjusted
by the said adjustable electrical source or magnetic energetic
source.
(B) The positioning micro adjusting methods used in the XY co-nS,inates are as follows: (1) The common driving moving bod is installed by the directional
difference 900 of the deformations between two sets transducers.
The said method is suitable for the adjustment of extra micro
quantity, in which two sets transducers drive their coupled
mechanisms respectively. Using two sets transducers and
needle bearings 609, 609 installed on two sides of reflex
reflectors 605 which are located with 900 to the reflex mirror
for driving reflex reflector to make scanning swinging with
the micro adjustment. The practical application of the said
structure is used for Laser printing machine as shown in Fig. 6.
The main structural feature is that two sets transducers 601,
602 are controlled by the driving electrical source 606 con
trolled by the scanning vihrator 605 to drive reflex reflector
611 with needle bearings on its two sides for making a
scanning displacement based on the bearing swinging; Fig 6-h shows another side formed by the adjusted deformation displace
ment transducer 603 with angular displacement and its coupled
and drived mirror piece 604, in which the said trasducer is
driver by its driving electrical source 607 by means of its
scanning vihrator 608.
(2) It is installed on two sets sliding base seats with independent rough precision adjusting drive and locking equipment and
located at the cross position with 900(or certain angle).
'The detormation direction of the transducer is same as its
coupled direction. The said method is suitable for the
adjustment with large movement quantity.
It is the structural application of the said point(2), in
which the said transducer is used for the micro adjustment
of final micro displacement with larger displacement quantity.
It can be used for micro adjustment of jig grinder, jig
borer or high precision measuring instruments, and cell injection or other cross coordinate equipment. During the
application, the said transducer can be operated by the
manual adjustment. Excepting it, the precision driving mecharusum (for example, the systems driven by the servo
motor or precision guide screw) can be also driven by the
digital instruction for coupling with the precision positioning.
(C) The micro displacement mechanism and method used in three
axial adjustment by way of the controll of electric energy or
magnetic energy on the deformation quantity of the machine
deformation displacement transducer contains the working or
the measurement or other processing equiptent# Its method contains: (1) It is composed of 3 sets transducers which show X.Y.Z.
or#entin# deformations respe#tively for driving commonly 2 moving body. They have independent adjustable driving
electrical sources respectively.
(2)It is composed of 3 sets transducers installed respectively
on the locked sliding base seats with X.Y.Z. three dimensional
axes for independent displacement adjustable drive, in which the
deformation direction of each transducer is the same as its
coupled axlaldirection and controlled by independent adjust
able driving electrical source.
When the structure described in point (1) is used in the cutting
of crystal piece or sculpture working, the left and right
displacement as well as the front and return displacement are
generated by X and Y axial transducers, and the depth displace
ment is generated by Z axial transducer. The deformation
according to the program instruction is controlled by the human or by the digital control instruction, as the present
applicable digital control tooling machine, in which the servo motor and precision steel ball screw rod are replaced by the
transducers which can make the deformation displacement.
Moreover, in the point(2), the transducers are installed alone
or installed on the said structure used for digital control
driving element, so that it can be used for the adjustment
of last extra micro quantin-.
TY#e moving body of the said structure can be used for the
working cutters or for the measuring instruments or for
laser equipments or for a cell injector or for the high
frequency response control which needs X.Y.Z. axial precision
displacement adjustment.
(D) The angle deformation displacement control is composed of the
twisted ted transducers, as shovn in Fig. 6-A, it is driven by the
electrical circuit and the angle displacemtn is controlled by
the quantity of the input electrical energy on the angle dis
placemen adjusting equipment for making the micro control
function.
(E) Concerning the multi-axial application, many sets transducers
accept respectis-el- the input actualing energy to generate the common or the individual deformation displacemenT for driving
various measuring instruments or optical or machine movable
elements.Fig. 7 is an applicable example of the laser printing
machine, in which the current lens used forthe scannin is
replaced by a set of lens 705 supported by 4 sets of transducers 01, 702, 703, 704. The said 4 sets transducers are controlled by the driving electrical source 706 and scanning vibrator 7C'7 for generating the deformations one by one, so that the lens
705 will generate the scannin displacement period.The further features are as follows:
- The condense lens (or condense reflector or output reflector .or output reflector or laser medium used for generating the
exaited light) located on the. said transducers can generate
the following functions by means of ON or OFF driving program
instructions on the X and Y coordinate axes controlled by the
microprocessor or computer based on the sampling signs or
character or diagram signs of the inlaid original copies::
- A character or diagram scanning track is gotten by the character
vector movement;
- e said displacements contain X-axial horizontal deformation disformation displacement and the vector displacement generated 1n- the said two displacements;
- The excited light generator can "cut outer or "emit" the signs
in the displacement according to the instructions 5 presented character or diagram shapes.
When the said main functions are used for making displacements in various laser applicable equipments,the speed of its frequency response is better than the present various tes. In the said various applications, the displacement function can be ac.hie-ed by the transducers which can change the electrical energy inter machine deformation displacement. If the driven assembly itself ls composed of the transducers, then the compound driving electrical energy can be inputed by the said elements at the same time.
For example, when the cutter used for cutting the ultrasonic wave makes a micro cutter-feeding, he cutting vibration and the micro feeding quantity can be controlled at the same time by
DC voltage adjusted on the magnetizing coils of the transducers which can generate the ultrasonic vibrations, When we want to make a micro adjustment on a quartz lens with piezoelectric effect, the deformation axial direction of the quartz lens can be made as the required deformation axial direction, including: axial deformation thickness (as shown in Fig. 8), wherein the quartz is cut in the direction of X-axe to Z-cut lens, and the ring-shaped conducting membranes are plated on the outer ring of two side of the lens for inputing the electrical energy in order to generate the axial deformation, and then the deformation quantity is changed by the adjustment of the input electrical energy for adjusting the focal distance.
When the used element is a magnetizing elastic te in the said various applicable examples, the method of magnetic field adjustment contains the coils excited by the input electrical current or the adjusted permanent magnet applying a magnetic field strength on the said elements for changing its deformation quantity.
Furthermore, when the applied energy increases or decreases in the transducers in spite of pieozo electric type or electric field elastic type, it has always a slight delay phenomenon and the off set arisen from zero during the input.
In order to rise its precision degree, the input electrical source of transducers in electric fielf elastic type or in pieozoecric effect type can be designed as a switch, so that it has a base electric current value with the polarit+ always same as the input adjusted electric source; similarly, the magnetic hysteresis elastic tlpe transducer can be designed b the input electric source as that it has a base magnetizing current with the polarity same as the input adjusted electrical source or that the permanent magnet is used for replacing the said base magnetizing current.
Based on the above, the present invention pro#ides a solid element for replacing the dynamic mechanism in order to make a more precision micro displacement drive with lower cost and finer micro adjustment. In the acceptance of the digital control drive, the small size has quicker frequency response.
It can increase the micro drive effect of the precision machines, measuring instruments, optical instruments or other applicable equlpements. Please examine it.
