According to the precise miniature universal coupling for the instrument, the precision problem in the installation coaxiality error compensation between the precise rotary sensor and the main engine to be measured is solved, and the precise miniature universal coupling is a novel miniature universal coupling, and has the advantages that the structure is simple, the batch production is easily realized, and a more positive effect is provided for promoting the application of the precise rotary sensor.
Description
Technical field
The utility model belongs to the drive technology field of modern high-precision rotary type sensor coupling shaft, specifically a kind of instrument accurate miniature Hooks coupling universal coupling.
Background technique
As everyone knows, precision rotation sensor be developed recently get up as photoelectric encoder, magnetic encoder etc.The appearance of precision rotation sensor makes the measurement of whole industry and control technique obtain a larger lifting, and grade of accuracy is by more than 20 original " left and right has risen to 5 ".But how to stop when coaxiality error is larger in installation process, the compensation precision ability that guarantees coupling just becomes a relatively difficult problem, reason is that the coupling in 0.2mm left and right connects by error compensation conventionally, modern high-precision rotary sensor is greater than place more than 0.5mm at some and tested main frame apart from each other and coaxiality error, conventional error compensation coupling just cannot use, and uses common gimbal structure to have drive gap, driving error large.
Summary of the invention
The purpose of this utility model is to provide a kind of instrument accurate miniature Hooks coupling universal coupling, and it is that elastic force between precision rotation sensor and tested main frame and transmitting torque and error compensation are integrated the transmission connecting mechanism without driving error.
The purpose of this utility model is achieved in that this instrument includes two fork-shaped coupling bodies with accurate miniature Hooks coupling universal coupling, it is characterized in that: the axial region of described two fork-shaped coupling bodies is respectively used to connect tested main frame transmission shaft and precision rotation type sensor, fork-shaped front end symmetrical position at fork-shaped coupling body is respectively provided with a vertebral foramen, in vertebral foramen, be provided with by the steady centrum of the fixing adjustment of locking nut, the vertebra portion that adjusts steady centrum inserts and is arranged in the vertebral foramen of the steady centrum of pass on elastic ring; The steady centrum of described pass totally four be distributed on elastic ring, except two, by adjusting steady centrum and locking nut, connect the steady centrum of pass fork-shaped coupling body and also by adjusting steady centrum and locking nut, be connected with one " work " type centre and turn.
Advantage of the present utility model and beneficial effect are as follows: it has solved the precision problem in the installation coaxiality error compensation between precision rotation inductor and tested main frame, it is kind of a novel miniature Hooks coupling universal coupling, have simple in structure, be easy to batch production, for promoting the use of precision rotation inductor, provide again more wide space.Main application has the industries such as precision measuremnt, war industry, aviation, navigation, chemical industry, oil.

Embodiment
According to Fig. 1-5 pair the utility model, be described in detail.Of the present utility model it include two fork-shaped coupling bodies 5, the axial region of two fork-shaped coupling bodies is respectively used to connect tested main frame transmission shaft 7 and precision rotation type sensor 8, fork-shaped front end symmetrical position at fork-shaped coupling body is respectively provided with a vertebral foramen, in vertebral foramen, be provided with by the steady centrum 3 of the fixing adjustment of locking nut 2, the vertebra portion that adjusts steady centrum 3 inserts and is arranged in the vertebral foramen of the steady centrum 4 of pass on elastic ring 6; The steady centrum 4 of pass totally four be distributed on elastic ring 6, except two, by adjusting steady centrum and locking nut, connect the steady centrum of pass fork-shaped coupling body and also by adjusting steady centrum and locking nut, be connected with one " work " type centre and turn 1.
During use, as shown in Figure 6, tested main frame transmission shaft 7 is connected with accurate miniature Hooks coupling universal coupling with precision rotation type sensor 8 use instrument, the fastening and transmitting torque with Cock screw 9.Precision rotation type measuring transducer 8 and tested main frame transmission shaft 7 are being installed under the impact of various different errors, and two axles can produce the not phenomenon on same shaft axis, and deviation forms and can be divided into the compound of oblique and perpendicular distance type or above two kinds.By elastic ring 6, stablize cone 3 and the steady cone 4 of pass has formed two Oldham's couplings with adjusting.Steady centrum gapless friction between the conical surface rotatablely moves in the course of the work, to compensating from All aspects of error, has both guaranteed the compensation of coaxiality error, exists again without any idle stroke.
Realized in sum the purpose of this utility model.
