A kind of micro-clamp includes driving source, three part of caliper and servicing unit；It is inboard that described servicing unit and driving source are located at caliper inner arm；Described driving source respectively has a servicing unit up and down, and driving source is using intellectual materials such as piezoelectric ceramics, rareearth super magnetostrictive alloys；Described caliper mechanism adopts circular arc type flexible hinge, and the components such as base, inner arm, outer arm, linking arm, jaw are cut out on monoblock elastomeric material, and caliper mechanism is symmetrical；Described jaw is located at outer arm top, and driving source and servicing unit are located on same vertical direction.Caliper structural behaviour is excellent, caliper compact conformation, saves space, and is capable of achieving secondary amplification, space has been saved while limited multiplication factor is met.
Description
Technical field
The present invention relates to pincers worker clamping device technical field, is specifically related to a kind of new micro-clamp caliper.
Background technology
Intellectual material is adopted modern micro-clamp for driving source more, although the intellectual materials such as piezoelectric ceramics, rareearth super magnetostrictive alloy have very high Motion Resolution rate, but which drives scope relatively small, therefore micro-clamp caliper is typically using the compliant mechanism with function of displacement amplification.
Chinese invention patent（Application number：201210268194.4 the applying date：2012-07-30）Disclose a kind of precise plain vice, including base, clamp block, leading screw, semi-round ball, regular jaw and moving jaw, described leading screw is connected by feed screw nut with semi-round ball, described moving jaw is provided with semicircle ball recess, moving jaw is connected with semi-round ball by semicircle ball recess, leading screw is fixed in clamp block by leading screw retainer plate, described moving jaw and regular jaw are designed with jaw plate, alignment pin, jaw positioning key and jaw location-plate, described jaw positioning key is arranged in the groove of jaw plate, jaw locating piece is stuck in the groove of jaw plate, regular jaw is fixed in clamp block by retainingf key, described clamp block and base are bolted, clamp block is rotated around base by live spindle.The present invention provides a kind of precise plain vice, and by being provided with a pair of planar bearing at the two ends of leading screw, leading screw flexibly can rotate, and solve the problems, such as that screw mandrel is locked, easy to use.
The content of the invention
For the caliper structure of excellent, the present invention is based on two grades of circular arc type flexible hinges and lever amplification principle, devises a kind of new micro-clamp caliper, space has been saved while limited multiplication factor is met.
The technical solution adopted for the present invention to solve the technical problems is：
Described micro-clamp includes driving source, three part of caliper and servicing unit；It is inboard that described servicing unit and driving source are located at caliper inner arm；Described driving source respectively has a servicing unit up and down, and driving source is using intellectual materials such as piezoelectric ceramics, rareearth super magnetostrictive alloys；Described caliper mechanism adopts circular arc type flexible hinge, and the components such as base, inner arm, outer arm, linking arm, jaw are cut out on monoblock elastomeric material, and caliper mechanism is symmetrical；Described jaw is located at outer arm top, and driving source and servicing unit are located on same vertical direction.Described left and right inner arm can be rotated rotating around circular arc type flexible hinge 1 and 8；Described left and right outer arm can be rotated rotating around circular arc type flexible hinge 4 and 7.
Preferably, described driving source is using intellectual materials such as piezoelectric ceramics, rareearth super magnetostrictive alloys.
Preferably, leaving gap between described inner arm and outer arm.
Preferably, described caliper mechanism adopts circular arc type flexible hinge, the components such as base, inner arm, outer arm, linking arm, jaw are cut out on monoblock elastomeric material.
Preferably, described caliper mechanism is symmetrical.
The invention has the beneficial effects as follows, composite and flexible hinge is more suitable for the engineer applied of high accuracy big displacement, and caliper structural behaviour is excellent, caliper compact conformation, saves space, and is capable of achieving secondary amplification, space has been saved while limited multiplication factor is met.

Specific embodiment
As shown in figure 1, described micro-clamp includes driving source, three part of caliper and servicing unit；It is inboard that described servicing unit and driving source are located at caliper inner arm；Described driving source respectively has a servicing unit up and down, and driving source is using intellectual materials such as piezoelectric ceramics, rareearth super magnetostrictive alloys；Described caliper mechanism adopts circular arc type flexible hinge, and the components such as base, inner arm, outer arm, linking arm, jaw are cut out on monoblock elastomeric material, and caliper mechanism is symmetrical；Described jaw is located at outer arm top, and driving source and servicing unit are located on same vertical direction.
In the presence of driving source, left and right inner arm is turned out rotating around circular arc type flexible hinge 1 and 8, can be amplified displacement in inner arm lower end, and the lower end of outer arm is acted on by linking arm, left and right outer arm is driven inwardly to rotate rotating around circular arc type flexible hinge 4 and 7, jaw shrinks.
