Abstract
The invention discloses a kind of six degree of freedoms for being installed on high-precision weighing balance to decouple counterweight loading device, when mainly solving load counterweight, counterweight mass center and not shaking when on a plumb line of scale pan lower draw-bar, and then the problem for causing balance reading dispersibility larger.Pallet inner ring structure is designed using gap type, this design can cooperate the load for realizing cylindrical body and spherical counterweight with manipulator, and notch symmetry direction is used to balance pallet mass center 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 and adjusts to the horizontal equilibrium of pallet.The present invention is adaptable to high-precision weighing balance weights load occasion, mainly solves the problem of that inclination load counterweight causes pallet acutely to shake and measurement accuracy is caused to decline.This pallet three-point support structure designs the counterweight that can be compatible with balled form and plain cylindrical form simultaneously.
Description
Technical field
The invention belongs to field of precision instruments, specially a kind of six degree of freedom decouples loading device.
Background technique
In the measurement process of high-precision weighing balance, counterweight to be measured is needed repeatedly, to be steadily loaded on pallet, by
It is difficult to contact simultaneously with tray surface in counterweight surface, inclination contact will lead to weight tray and generate acutely shaking, in turn result in
The reading dispersibility of balance is larger, needs just settle out for a long time, such to impact the accuracy that also will affect measurement, and shows
There is plane pallet to be unable to satisfy standard test weight (silicon ball) bearing requirements of balled form, the uncertain mistake that furthermore manual loading introduces
Difference also will affect measurement accuracy.
Summary of the invention
In order to solve to shake using caused during traditional scale pan load counterweight, and balled form counterweight cannot be compatible with
The problem of, the invention proposes a kind of novel six freedoms for being installed on weighing balance to decouple counterweight loading device.The present invention with
Manipulator combines, and can effectively eliminate impact when counterweight load and the shaking of scale pan, while can carry balled form and general
Logical post type counterweight.
The present invention solves the above problems used technical solution are as follows:
The present invention includes inner ring support holder structure, centre circle pallet connection structure, outer ring support holder structure, knife edge type connection, counterweight
Support column, balanced structure, manipulator.Inner ring pallet is open type structure, this structure is matched with manipulator realizes taking for counterweight
It puts, while the opposite side that is open carries out hollow design and realizes pallet sole mass balance；3 support columns are installed among inner ring pallet,
Silicon ball shape and plain cylindrical counterweight can be carried simultaneously；Inner ring pallet lower end is connected through a screw thread balancing pole, and connecting rod lower end is 4
Screw thread balancing pole junction, balancing pole are separately connected 4 counterweight nuts；Inside and outside circle pallet passes through knife edge structure and middle coil structures
It links together, the edge of a knife is screwed with inner ring, outer ring by being inserted into keyway respectively.
The present invention it has the advantage that:
Avoiding inclination load counterweight through the invention causes pallet acutely to shake the case where causing measurement accuracy to decline,
Torque caused by counterweight can be loaded to inclination using decoupling-structure inside pallet to be effectively decoupled, while three-point support structure
Design can be compatible with the counterweight of balled form and plain cylindrical form simultaneously.
