Description
Technical field
This utility model is related to school's vernier height gauge and returns to zero positioner.
Background technology
At present band table height gauge is relative with digital display height gauge price and common vernier height gauge will exceed a lot, and uses
The relatively common vernier height gauge of stability also lower, thus leading to its popularization to be restricted, so common vernier is high
Degree chi is in machine-building workshop and school's practice workshop using still especially extensive.Certainly, vernier height gauge also has its deficiency
Place, that is, using a period of time after, " 0 " position on blade and vernier does not line up causes read untrue, that is, there is initial error,
Lead to misread.
Further, since needing accurately correction zeroing, virtually increased production, the system of the manufacturing enterprise of vernier height gauge
The workload such as make, assemble, checking, be badly in need of one kind easily and efficiently balancing controls solving this problem.
The adjusting zero method of existing vernier height gauge mainly has following three kinds：
1st, blade adjusting method：The retention mechanism of blade and base is somewhat unclamped, moves up and down fine setting blade, reach correction
The purpose of zeroing；
2nd, pad copper sheet method：Upper groove or lower groove pad scale copper in the connection frame of vernier and line measuring jaw；
3rd, filing：On grinding machine, processing line measuring jaw and the interface of vernier are to remove initial error.
First method blade adjusting method is reliable, but wastes time and energy, and needs to adjust up and down blade, sometimes handss
On somewhat many certain strength, position will be adjusted, need to adjust again from newly；Second method pad copper sheet method, is on the one hand difficult to
Grasp its accuracy, after copper sheet pad gets on, may still have the presence of some errors, be difficult to accurately elimination and do not line up problem,
Relative error magnitudes can only be reduced, still further aspect also needs to prepare the scale copper of all size；The third method filing, though
So accuracy is higher, but also can there is mismachining tolerance, and the feasibility in addition operating is poor, and not necessarily each unit can have mill
Bed, and process of realizing is also irreversible, rethinks recovery and be impossible to after grinding, is a kind of destructive adjusting zero method, repaiies
Just, adjustment process is very loaded down with trivial details, wastes time and energy, and needs professional just can be adjusted revising, but also may not essence
Really revise.
In sum, vernier height gauge is not to zero difficult problem in its makeover process and its control of accuracy, revise,
Adjustment process is very loaded down with trivial details, and its accuracy is difficult to control to.
Content of the invention
This utility model be directed to the deficiencies in the prior art, there is provided a kind of according to the first reliable adjusting zero method,
The principle of infinitesimal displacement can be realized in conjunction with worm drive, realize the fine setting of height gauge blade using thread transmission, side
Just again quick, manufacturing cost is also low, the vernier of the needs of production of suitable users and vast school practice workshop needs
Height gauge null setting.
For realizing this utility model purpose, there is provided technical scheme below：Vernier height gauge null setting it is characterised in that
Including rectangular tube mounting platform, the U-shaped support being fixedly installed on rectangular tube mounting platform, U-shaped support and rectangular tube are installed flat
Platform is mutually perpendicular to, and downwards, two side is fixedly connected U-shaped support notch with direction pipe mounting platform two side, and rectangular tube is installed flat
Fine setting screwed hole is offered on platform upper surface central longitudinal axis, fine setting screw thread in the hole is connected with micrometer adjusting screw from the bottom up, U-shaped
Frame top end surface center offers central through hole, and central through hole both sides and central through hole are coaxially arranged with guide through hole, and guiding is logical
In the hole is inserted with the first lead, is inserted with housing screw in central through hole, and housing screw end spins and is fixed with compact heap, compression
The corresponding first lead end of block offers screwed hole, and the first lead end and screwed hole spin fixation, and housing screw covers
It is connected to holddown spring, holddown spring is arranged between compact heap and U-shaped cantilever tip.
Preferably, U-shaped support either side wall, it is provided with fine setting positioning dress above rectangular tube mounting platform upper surface
Put, fine setting positioner includes the fine setting locating piece that regulating bolt is connected with regulating bolt end, and fine setting locating piece is provided with
Symmetrical guide through hole, guide through hole interpolation is provided with the second lead, and U-shaped rack side wall is fixed in second lead one end
On, regulating bolt is rotatably connected in the threaded adjusting in the hole that U-shaped rack side wall correspondence opens up.
This utility model beneficial effect：This utility model can be real with reference to worm drive according to vernier height gauge adjusting zero method
The principle of existing infinitesimal displacement, realizes the fine setting of height gauge blade using thread transmission, and structure is simple, low manufacture cost,
It is easy to operation, the needs of production of suitable users and vast school practice workshop needs.
