Background technology
Pendulum type gyroscope north searching instrument is a kind of inertia north finding device of classics.Its major function is to provide astronomical north to azimuth reference, can be used for measurement target (as 2 lines or level crossing, prism normal etc.) with respect to the position angle of this benchmark north orientation.Pendulum type gyroscope north searching instrument is widely used in fields such as armament systems, geodetic surveying, mapping, civil engineering (road construction, dam, bridge), underground installation, pit mining, tunnel construction and oil prospect pits, accurately determines rapidly the initial orientation of different objects.
Carry and transportation demand in order to satisfy, pendulum type gyroscope north searching instrument need to adopt split-type structural, total powerstation (perhaps transit) with seek northern instrument main frame and can achieve a butt joint and separate.In working order, total powerstation (perhaps transit) with seek northern instrument main frame and be in the butt-joint locking state; Under off working state, total powerstation (perhaps transit) with seek northern instrument main frame and be in released state, and packing is beneficial to and carries and transport respectively.The repetition merging precision of butt joint locking mechanism is very large on seeking northern instrument measuring accuracy impact, in order to guarantee to seek the measuring accuracy of northern instrument, requires the repeatable accuracy deviation control of docking mechanism within the specific limits.
Newly the latch mechanism of a kind of high repetitive positioning accuracy of development, realized total powerstation and sought northern instrument main frame high precision rapid abutting joint and separate, and the suitable application area tool that enlarges pendulum type gyroscope north searching instrument is of great significance.
Summary of the invention
The purpose of this utility model is to provide a kind of latch mechanism of high repetitive positioning accuracy, and it can be realized total powerstation and seek northern instrument main frame high precision rapid abutting joint and separate.
The utility model is to realize like this, a kind of latch mechanism of high repetitive positioning accuracy, it comprises the total powerstation base and seeks northern instrument base, connect firmly three cylinders on the total powerstation base, radially evenly distribute, connect firmly three legs on the total powerstation base end face, seek and connect firmly three pairs of accurate steel balls on northern instrument base, radially evenly distribute, trim ring with seek northern instrument base and connect firmly, chuck has screw inclined plane, is arranged in the mode of shaft hole matching and seeks between northern instrument base and trim ring, and toggle is arranged in the mode of shaft hole matching and seeks on northern instrument base.
The bottom surface of total powerstation base arranges spacing hole, and the end face of seeking northern instrument main machine base arranges stop screw.
The utility model has the advantages that 1) this mechanism space is compact, easy to operate, docking and velocity of separation fast; 2) repetitive positioning accuracy is high, and error is constant; 3) have the position limitation protection function, guarantee the docking location uniqueness.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
The utility model can be realized total powerstation and seek northern instrument main frame high precision rapid abutting joint and separate.It utilizes three pairs of accurate steel balls, three accurate cylinders, a locking chuck, a toggle to form butt joint locking mechanism, realizes total powerstation and seeks the reliable positioning and locking of northern instrument main frame six degree of freedom.
As shown in the figure, connect firmly three cylinders 4 on total powerstation base 3, radially evenly distribute; Connect firmly three legs 5 on the total powerstation base end face, leg has helicla flute.Seek and connect firmly three pairs of accurate steel balls 9 on northern instrument base, radially evenly distribute.Trim ring 12 with seek northern instrument base 8 and connect firmly, chuck 11 has screw inclined plane, is arranged in the mode of shaft hole matching and seeks between northern instrument base 8 and trim ring 12, chuck 11 can freely rotate take trim ring 12 as axle.Toggle 10 is arranged in the mode of shaft hole matching and seeks on northern instrument base 8, stir toggle 10 can drive chuck 11 along trim ring 12 rotations.Wherein total powerstation also can be changed to transit.
Total powerstation is when seeking northern instrument and dock, three cylinders on the total powerstation base are aimed at respectively three pairs of steel balls seeking on northern instrument main machine base, after contacting fully, both stir the rotation of toggle drive chuck, the screw inclined plane of chuck and the helicla flute of leg are combined closely, each cylinder is pressed on corresponding a pair of steel ball, thereby the six-freedom degree of restriction total powerstation is realized total powerstation and the rapid abutting joint of seeking northern instrument main frame.
Total powerstation is stirred the toggle drive chuck when seeking northern instrument main frame and separate, and the screw inclined plane of chuck is separated with the helicla flute of leg, and each cylinder is disappeared with the snap-in force that adds of corresponding a pair of steel ball, realizes total powerstation and seeks separating fast of northern instrument main frame.
In order to guarantee the uniqueness of docking location, in the bottom surface of total powerstation base 3, spacing hole 6 is set, at the end face of seeking northern instrument main machine base, stop screw 7 is set.During docking, only have stop screw to insert spacing hole after chuck could lock, thereby the uniqueness of the position that achieves a butt joint.
