Description
Technical field
The present invention relates to school's vernier height gauge zeroing positioning devices.
Background technique
Band table height gauge and digital display height gauge price will be higher by much with common vernier height gauge relatively at present, and be used
The relatively common vernier height gauge of stability it is also lower, be restricted so as to cause its popularization, so common vernier is high
Ruler is spent to use still especially extensively in machine-building workshop and school's practice workshop.Certainly, vernier height gauge also has its deficiency
Place, i.e., after a period of use, " 0 " position on blade and vernier, which is misaligned, causes read untrue, that is, there is initial error,
Cause to misread.
Further, since needing accurate correction zeroing, production, the system of the manufacturing enterprise of vernier height gauge are virtually increased
It the workloads such as makes, assemble, examining, being badly in need of a kind of easily and efficiently balancing controls to solve this problem.
It translates
The adjusting zero method of existing vernier height gauge mainly has following three kinds:
1, blade adjusting method: the retention mechanism of blade and pedestal is slightly unclamped, fine tuning blade is moved up and down, reaches amendment
The purpose of zeroing；2, it pads copper sheet method: padding scale copper in the upper slot or lower slot of vernier and the connection frame of scribing line measuring jaw；3, it is ground
Method: the interface of processing scribing line measuring jaw and vernier is on grinding machine to remove initial error.
First method blade adjusting method is reliable, but time-consuming and laborious, needs to adjust blade up and down, sometimes hand
On slightly how certain strength, position will be adjusted, need to adjust again from newly；Second method pads copper sheet method, is on the one hand difficult to
The presence of some errors may still be had after copper sheet pad gets on by grasping its accuracy, be difficult accurately elimination and be misaligned problem,
Relative error magnitudes can only be reduced, still further aspect also needs to prepare the scale copper of various specifications；The third method filing, though
Right accuracy is higher, but can also have mismachining tolerance, and the feasibility in addition operated is poor, and not necessarily each unit can have mill
Bed, and realize that process is also irreversible, recovery is rethought after grinding and is impossible to, and is a kind of destructive adjusting zero method, is repaired
Just, adjustment process is very cumbersome, time-consuming and laborious, and needs professional that can just be adjusted amendment, but also may not can be smart
Really amendment.
In conclusion vernier height gauge is not in the control of its makeover process and its accuracy zero problem, amendment,
Adjustment process is very cumbersome, and accuracy is difficult to control.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of according to the first reliable adjusting zero method, in conjunction with
The principle of infinitesimal displacement may be implemented in worm drive, the fine tuning of height gauge blade is realized using thread transmission, conveniently again
Fast, manufacturing cost is also low, the vernier height for being suitble to the needs of production of users and vast school practice workshop to need
Ruler null setting.
Purpose to realize the present invention provides following technical scheme: vernier height gauge null setting, it is characterised in that including
Rectangular tube mounting platform, the u-bracket being fixedly installed on rectangular tube mounting platform, u-bracket and rectangular tube mounting platform phase
Mutually vertical, u-bracket notch is downward, and two sidewalls are fixedly connected with rectangular tube mounting platform two sidewalls, on rectangular tube mounting platform
Fine tuning threaded hole is offered on centre of surface longitudinal axis, is finely tuned in threaded hole and is screwed with micrometer adjusting screw, u-bracket top from the bottom up
End surfaces center offers central through hole, and central through hole two sides and central through hole are coaxially arranged with guide through hole, in guide through hole
It is inserted with the first guide post, housing screw is inserted in central through hole, housing screw end, which is screwed on, is fixed with compact heap, compact heap pair
The first guide post end is answered to offer threaded hole, the first guide post end and threaded hole are screwed on fixation, are socketed on housing screw
Holddown spring, holddown spring are set between compact heap and u-bracket top.
Preferably, any side wall of u-bracket, is provided with fine tuning positioning dress above rectangular tube mounting platform upper surface
It sets, fine tuning positioning device includes the fine tuning locating piece for adjusting bolt, connecting with adjusting bolt end, finely tunes and is provided on locating piece
Symmetrical guide through hole, guide through hole interpolation are provided with the second guide post, and u-bracket side wall is fixed in second guide post one end
On, it adjusts bolt and is rotatably connected in the corresponding threaded adjusting bore opened up of u-bracket side wall.
The invention has the advantages that: the present invention may be implemented minimum position according to vernier height gauge adjusting zero method combination worm drive
The principle of shifting realizes the fine tuning of height gauge blade using thread transmission, and structure is simple, low manufacture cost, convenient for operating,
The needs of production and vast school practice workshop for being suitble to users need.
