Abstract
The invention discloses a kind of six degree of freedom for being installed on high-precision weighing balance to decouple counterweight loading device, when mainly solving loading counterweight, counterweight barycenter and scale pan lower draw-bar not rocking when on a plumb line, and then the problem of cause balance reading dispersed larger.Pallet inner ring structure is designed using gap type, and this design can coordinate the loading for realizing cylinder and spherical counterweight with manipulator, and breach symmetry direction is used for balancing pallet barycenter using engraved structure；Three-level support holder structure connects composition decoupling-structure by the edge of a knife；Inner ring pallet lower end connects gravity regulating structure, realizes the horizontal equilibrium adjustment to pallet.The present invention is adaptable to high-precision weighing balance weights loading occasion, mainly solves to tilt loading counterweight and causes pallet acutely to rock, the problem of causing measurement accuracy to decline.This pallet three-point support structure design can simultaneously compatible balled form and plain cylindrical form counterweight.
Description
Technical field
The invention belongs to field of precision instruments, specially a kind of six degree of freedom decoupling loading device.
Background technology
, it is necessary to which counterweight to be measured repeatedly, is stably loaded on pallet in the measurement process of high-precision weighing balance, by
With tray surface it is difficult to contact simultaneously in counterweight surface, inclination contact will cause weight tray to produce acutely to rock, in turn result in
The reading dispersiveness of balance is larger, it is necessary to can just settle out for a long time, and such a impact can also influence the accuracy of measurement, and show
There is the standard test weight that plane pallet can not meet balled form（Silicon ball）Bearing requirements, the uncertain mistake that manual loading introduces in addition
Difference can also influence measurement accuracy.
The content of the invention
In order to solve to rock using caused during traditional scale pan loading counterweight, and can not compatible balled form counterweight
The problem of, the present invention proposes a kind of novel six freedom decoupling counterweight loading device for being installed on balance of weighing.The present invention with
Manipulator is combined, and the impact and scale pan when can effectively eliminate counterweight loading are rocked, while can carry balled form and general
Logical post type counterweight.
Technical scheme is used by the present invention solves the above problems：
The present invention includes inner ring support holder structure, centre circle pallet attachment structure, outer ring support holder structure, knife edge type connection, counterweight support
Post, balanced structure, manipulator.Inner ring pallet is open type structure, and this structure is engaged with manipulator realizes picking and placeing for counterweight, together
When be open offside carry out hollow out design realize pallet sole mass balance；3 support columns are installed among inner ring pallet, while can
To carry silicon ball shape and plain cylindrical counterweight；Inner ring pallet lower end is connected through a screw thread balancing pole, and connecting rod lower end is that 4 screw threads are put down
Weighing apparatus bar junction, balancing pole connect 4 counterweight nuts respectively；Inside and outside circle pallet is connected to by knife edge structure and middle coil structures
Together, the edge of a knife is screwed with inner ring, outer ring by inserting keyway respectively.
Its advantage of the present invention is：
By present invention, avoiding tilting loading counterweight to cause pallet acutely to rock the situation for causing measurement accuracy to decline, utilizing
Decoupling-structure can be effectively decoupled to torque caused by inclination loading counterweight inside pallet, while three-point support structure designs
Can simultaneously compatible balled form and plain cylindrical form counterweight.
