Close adjusting screw thread and fine adjustment threaded fasteners respectively have eight, and fine adjustment screw thread is each attached in connection ring；Eight precisions
It adjusts screw thread and is divided into two groups, every group is four, is respectively used to aligning and leveling；Specifically, four fine adjustment screw threads of aligning
The alternate equidistant arrangement of (referred to as aligning module) and four fine adjustment screw threads of leveling (referred to as leveling module), the i.e. essence of aligning
The close screw thread and the fine adjustment screw thread of leveling of adjusting is in 45 ° of angles；It is arranged in connection ring in fine adjustment screw thread installed position
There is installation hole location, fixing piece and fine adjustment are threadedly engaged installation, and fixing piece is mounted on connection ring inner wall direction；Connection ring and bottom
Seat is ensured to fix by four fine adjustment screw threads of aligning, and the center line of connection ring and pedestal keeps coaxial；Fine adjustment spiral shell
Line top is contacted with the skew wall of pedestal；Similarly, connection ring and objective table are ensured to fix by the four fine adjustment screws leveled, and
Keep the center line of connection ring, pedestal and objective table coaxial.
In the present invention, four screws of aligning module can be divided into two groups, wherein 180 ° of corresponding positions are one small
Group, unidirectional freedom degree for horizontal direction is adjusted, and has the function of single-degree-of-freedom locking；Four precisions of leveling
Adjusting screw is also two groups, wherein 180 ° of corresponding positions are a small group, for one degree of freedom in an inclined direction
Adjusting, while also have the function of single-degree-of-freedom locking.
In the present invention, the contact surface of fine adjustment screw thread and mechanism can carry out Surface hardening treatment, to guarantee enough
Rigidity.
It is had the following advantages due to using such as above-mentioned technical proposal, the present invention:
1, aligning module of the present invention and leveling module in the same plane, realize single section in while carrying out aligning, level
Function；
2, since aligning module and leveling module are in same plane, the height of regulating mechanism is greatly shortened, and reduces measurement process
The whole height of middle rotary type workpiece, to improve the precision of workpiece calibration process；
3, the higher fine adjustment screw thread of service precision, may be implemented the fine adjustment function of aligning and leveling；
4, device overall structure is simple, is easily assembled.
