Description
Technical field
The present invention relates to micro-/ nano field of locating technology, specially a kind of submissive actuating mechanism of creeping.
Background technique
With the development of micro-/ nano technology, all there is an urgent need to submicron orders, micro-/to receive for the research of numerous field of engineering technology
The precision positioning of meter level, and driver needed for big stroke, high-resolution Precision Position Location System must also have big stroke, height
Resolution ratio.But since traditional electromagnetic machine needs deceleration device, it is difficult to break through in micromation, high-precision developing direction, no
Adapt to the demand of modern precision machinery.With the development of material science, novel intelligent material is that these are new using proposing
Solution.
Intellectual material is easily controllable because being quick on the draw, and can be promptly restored to reset condition etc. again after outside stimulus is eliminated
Advantage is widely studied and applies in the production of non-electromagnetic principle driver, especially with piezoelectric material and magnetostriction materials system
At driving device it is with the fastest developing speed.The linear motor of piezoelectric material is applied with small in size, displacement resolution is high, output
Power is big, fast response time, the advantages that not generating heat, and has in precision positioning and has great advantage.
Piezoelectric type linear motor can be divided into ultrasound resonance formula, inertia-type, Inchworm type by driving principle is different again.Ultrasound resonance
Formula is compact-sized, small in size, light-weight, easily realizes miniaturization and lightweight, but due to being used to drive that friction is small, so
Power output is smaller, while because fretting wear is serious, therefore efficiency is relatively low with kinematic accuracy；Inertia-type principle and structure are simple,
Multifreedom motion can be achieved, but due to not having clamping institution, positioning keeps difficult, and power output is small.Inchworm type then overcomes super
The disadvantage that acoustic resonance formula power output is small, efficiency is low with kinematic accuracy and inertia-type power output is small, positioning is unstable has output
The advantages that power is big, power density is big, positioning stablity.
But there is also following deficiencies for current piezoelectricity looper linear motor: 1, volume is big, structure is not compact.2, motor
Stability is low.3, motor cannot power off clamp.4. can only move along a straight line, curvilinear motion can not achieve.For this reason, it may be necessary to design
A kind of new technical solution, which is given, to be solved.
