Description
Technical field
The utility model belongs to the engineering device technique field to generate and keeping machine or effective operation of apparatus, and in particular to arrives
A kind of inclination-angle regulating device of atomic fountain clock chamber phase shift evaluation.
Background technique
Cesium atomic fountain clock is current frequency reference, has highest accuracy performance.Chamber phase shift is Cesium fountain
One of main frequency displacement item of clock, microwave cavity are the most crucial components of fountain clock, and the microwave field in ideal microwave resonant cavity is
Pure stationary field, it is 0 that atom passes through the phase difference experienced when microwave cavity twice.But it is actually led since cavity wall has electrical loss
Cause it is intracavitary have certain traveling wave ingredient, Cs atom is up and down twice can be different with the phase experienced when microwave field interactions
It causes, microwave field certainly exists small phase difference, referred to as chamber phase distribution error, i.e. chamber phase shift twice.This is to Cesium fountain
Clock is a main error, depends primarily on irrelevance of the atom upthrow direction of motion with respect to ground plumb line.In experiment usually
Change the inclination angle of resonant cavity by changing fountain clock physical system inclination angle, runs frequency displacement and uncertainty, spray to measure it
Spring clock tilt adjustment measuring device plays a significant role in an experiment.
It is commonly designed the fountain clock leg device used and is a flat surface screw thread stabilizer blade, stabilizer blade is placed directly on floor,
The adjusting to fountain clock inclination angle is realized by adjusting screw thread, the disadvantage is that controllability is weaker, adjustment process does not have reciprocal
Property with repeatability.When adjusting screw thread, entire clock may generate translation and rotation, have a negative impact to the operation of clock.
There are also equipment to use adjustable leg device currently on the market, and degree of regulation is higher, but stability is poor, for quality
For big and high stability requirement fountain clock, it is not available.In addition, general stabilizer blade regulating device is fixed on floor,
The factors such as the vibration of surrounding can generate the operation of clock and seriously affect, and reduce its stability.
Utility model content
The technical problem to be solved by the utility model is to overcome existing fountain clock inclination-angle regulating device, provide
A kind of design is reasonable, structure is simple, the angular adjustment inclination-angle regulating device that accurately phase shift of atomic fountain clock chamber is evaluated.
Solving technical solution used by above-mentioned technical problem is: there are four regulating mechanism, four adjustings for setting on pedestal
The position of mechanism is corresponding with four stabilizer blades of atomic fountain clock, and regulating mechanism is to be machined with spherical groove on ball screw seat,
Inside of spherical groove is provided with ball screw, and ball screw pressure ring is provided on ball screw seat, and ball screw top is provided with lock
Tight nut and connecting plate.
As a kind of perferred technical scheme, the ball screw seat is that radial processing is recessed in the middle part of cylindrical and lateral wall
Slot, the circular hole to match with ball screw seat is machined on pedestal, and ball screw seat is mounted in circular hole and is fixed by presser feet.
As a kind of perferred technical scheme, the presser feet is L shape.
As a kind of perferred technical scheme, it is machined on ball screw above ball screw pressure ring along center line
Two symmetrical plane a are spanner gripping section.
The utility model beneficial effect is:
It is fixed on atomic fountain clock device on independent ground using the utility model, it is possible to prevente effectively from ambient vibration
Etc. factors interfered caused by fountain clock operation stability, sphere-contact makes atomic fountain between ball screw and ball screw seat
Four stabilizer blades of clock are vertical with ground holding or continuously change inclination angle, not only can be to atomic fountain clock by adjusting ball head screw rod
Each support foot hight is adjusted, and can accurately realize the adjusting to atomic fountain clock inclination angle, to more accurately survey
The chamber phase shift for measuring atomic fountain clock passes through sphere-contact and uses ball screw pressure ring between ball screw and ball screw seat
Fixed ball screw, not only facilitates four stabilizer blades and the ground for adjusting the phase shift of atomic fountain clock chamber but also locking being facilitated to make atomic fountain clock
Inclination angle the problems such as remaining unchanged, avoiding the rotation of clock body or translation that generate during tilt adjustment, the utility model has
Degree of regulation is high and stability is good.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that atomic fountain clock is equipped on the utility model.
Fig. 2 is regulating mechanism structural schematic diagram in Fig. 1.
Fig. 3 is ball screw seat 7 in Fig. 2, ball screw 3,6 attachment structure schematic diagram of ball screw pressure ring.
Specific embodiment
With reference to the accompanying drawings and examples to the utility model be further described, but the utility model be not limited to it is following
Embodiment.
In Fig. 1,2,3, the inclination-angle regulating device of the atomic fountain clock chamber phase shift evaluation of the present embodiment is by pedestal 1, bulb
