Solve the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of knife platform dovetail groove high-acruracy survey special gauge, including micrometer, guide rod, measuring staff, fixed block and sliding shoe；
The front end of the micrometer is equipped with sliding shoe, and the inside of sliding shoe is through offering for accommodating micrometer
Putting hole, and the two sides in putting hole of sliding shoe offer limit hole, the limit hole is arranged in parallel with putting hole, limit
The inner surface in hole is inserted with guide rod, and the other end of guide rod is cased with fixed block, and the inside of the fixed block is close to the position of guide rod
Through the sliding eye offered for guide rod sliding, runs through at the inside center of the fixed block and offer for installing measuring staff
The top outer surface of fixation hole, the fixed block and sliding shoe is equipped with dovetail side plate, the fixed block close to its relative position
A side external surface far from sliding shoe is movably installed with measuring staff nut.
Preferably, one end outer surface of the guide rod far from sliding shoe is equipped with M bolt, and M bolt by internal and external threads
Gasket is equipped between guide rod.
Preferably, the measuring staff is threadably secured close to one end of fixed block and is equipped with fixed link, fixed link it is outer straight
Diameter is identical as the interior diameter of fixation hole.
Preferably, the top outer surface of the sliding shoe is run through close to corner location offers bolt hole.
Compared with prior art, the utility model has the following beneficial effects:
The cubing of this practical design, by being respectively provided with and dovetail groove inner surface structure phase on the top of fixed block and sliding shoe
Same shape, can be simple and quick along with the length of measuring staff later by being spaced between detection fixed block and sliding shoe
Measure dovetail groove width numerical value；
When school zero, first rotation adjusts bolt, moves up so that adjusting bolt, later, places table in the front end of putting hole
The smooth object in face pushes the micrometer after zero along putting hole, finally rotation is adjusted as block to the direction of block
Bolt, so that adjusting, downward spiral is mobile, is cooperated using the internal and external threads for adjusting bolt and fixed internal surface of hole, squeezes thousand points
Ruler just completes school zero so that the position of micrometer is fixed, and zero process of school was not only simple but also quick；
By installing the measuring staff of different length, so that the length that the detecting distance of dovetail groove is equal to measuring staff is moved plus micrometer
Dynamic length improves the upper limit of detecting distance.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
Referring to Fig.1 shown in -3, a kind of knife platform dovetail groove high-acruracy survey special gauge, including micrometer 1, guide rod 2, measuring staff
3, fixed block 4 and sliding shoe 8；
The front end of micrometer 1 is equipped with sliding shoe 8, and the inside of sliding shoe 8 is through offering for accommodating micrometer 1
