Abstract
The invention discloses a guardrail type step pitch gauge and belongs to a measuring tool. The guardrail type step pitch gauge is composed of a reference end cover, a pedestal, an auxiliary end cover, a workload block, a cushion block and a tightening screw, wherein the two end covers are connected with the pedestal by using inner hexagonal screws, the workload block is arranged in a pedestal groove and is fittingly ground with the cushion block, and a guardrail may form a one-body structure with the pedestal or objects in other shapes form detachable or non-detachable connection with the pedestal. The guardrail type step pitch gauge has the advantages of high working size precision, convenient use, good stability, and anti-impact and anti-bump performance. The guardrail type step pitch gauge is mainly used in proof reading of a laser interferometer, detection of a numerical control machine, detection of a coordinate measuring machine and other precise instruments.
Description
Affiliated technical field
The present invention relates to a kind of measurer, be specially a kind of guardrail-type step gage.
Background technology
Step gage is the length standard device in kind that precision measurement of length is used, and is to be arranged at regular intervals in the step gage matrix by several work gauge blocks the high-precision multivalues material measure formed.For proofreading laser interferometer, detecting numerically-controlled machine particularly high-grade, digitally controlled machine tools, detection three coordinate measuring machine, imaging optical instrument and other exact instrument.At present only have in the world the enterprise of a few countries can produce step gage, China is one of country wherein.
Step gage is the measuring appliance of superprecision, and its working size precision and stability thereof are vital technical indicators.Except manufacturing technology affects this index, in transporting, use and taking care of, all to be especially careful.As by accidental shock or collision, will affect the working size precision.There are following three kinds of versions in existing step gage: (1) evagination lapping-in type step gage, it is characterized in that the work gauge block protrudes matrix, work gauge block and cushion block lapping-in, and Fig. 1 is this evagination lapping-in type step gage, due to the process lapping-in, so its precision is high.Because its evagination is convenient to the workplace of instrument gauge head at orthogonal both direction turnover work gauge block, thus very easy to use.But also, because of the poor stability of its evagination step gage working size, once be collided, original precision will be lost; (2) inner concave shape step gage, is characterized in that in the recessed matrix groove of work gauge block, work gauge block and cushion block lapping-in, and Fig. 2 is indent lapping-in type step gage, because its work gauge block all is recessed in the matrix groove, revetment protection is on every side arranged and good stability of the dimension.But there is revetment its indent both sides and uses inconvenience, particularly when the check number controlled machine, the gauge head turnover of supplementary instrument (being generally dial test indicator) can only pass in and out in short transverse, at Width (laterally), can not pass in and out, and to use, brings very big inconvenience; (3) the non-lapping-in type of indent step gage; it is characterized in that in the recessed matrix groove of work gauge block; work gauge block and cushion block be lapping-in not; Fig. 3 is the non-lapping-in type of indent step gage; also, because its work gauge block all is recessed in the matrix groove, revetment protection is on every side arranged and good stability of the dimension, but its indent both sides there is revetment and uses inconvenience; do not pass through lapping-in, its precision is relatively low.
Summary of the invention
For above-mentioned situation, the present invention discloses a kind of guardrail-type step gage, belongs to guardrail lapping-in type step gage.The guardrail of spaced arrangement is with work gauge block common point above matrix, and work gauge block and cushion block lapping-in are arranged in the matrix groove.The technical solution adopted in the present invention is: the guardrail-type step gage mainly by benchmark end cap, pedestal, auxiliary end cap, work gauge block, cushion block, hold out against screw and form.Two end cap is connected with pedestal with socket head cap screw, the gauge block of working be placed in base seat groove and with the cushion block lapping-in.Guardrail is divided into integral structure, the non-disconnectable connection or releasable connection with the combining form of pedestal.Guardrail Protection gauge block, from impact, the collision of side direction, does not affect again the normal use of work gauge block measurement face.
After adopting such scheme, overcome the defect of Fig. 1, Fig. 2 and these three kinds of structures of Fig. 3, made it have the working size precision high, easy to use, good stability, have the outstanding advantages of protecting against shock, collision.Be widely used in the check and correction laser interferometer, detect numerically-controlled machine, detection coordinates measuring machine and other exact instrument.
It is all convenient that the guardrail-type step gage is used, takes care of and carries, and dimensional stability is high, has thoroughly overcome the significant drawbacks of current other form step gage, very favourable to the popularization and application of step gage.
The guardrail-type step gage develops high-end manufacturing industry to China, especially develops and promotes the use of the medium and high classes numerically-controlled machine multiple large meaning is arranged is self-evident.
Use the guardrail-type step gage, can also improve the precision of general NC lathe, be convenient to promote the use of in workshop condition.

In figure, auxiliary end cap 4. cushion block 5. work gauge block 6. socket head cap screws 7. of 1. benchmark end cap 2. pedestal 3. hold out against screw
Embodiment
From Fig. 3, Fig. 4, Fig. 6, can find out, benchmark end cap 1 use socket head cap screw 6 is connected with pedestal 2 left sides, auxiliary end cap 3 is connected with pedestal 2 right sides, cushion block 4 and the mutual lapping-in of work gauge block 5, be placed in the middle slot of pedestal 2, according to the specification of step gage, work gauge block 5 use cushion block 4 lapping-ins, make its lapping-in to very accurate precision, hold out against screw 7 and be threaded with auxiliary end cap 3 middle-ends.
From Fig. 4, Fig. 5, also can find out, the upper end, both sides of pedestal 2 has with spaced guardrail.Guardrail and pedestal 2 are an one-piece construction.There is guardrail work gauge block 5 just can not be subject to the external force collision, made the step gage precision be able to long-term maintenance.While with indicating gauge, measuring operation, very convenient.Guardrail is higher than work gauge block 5.There are 3 protection of benchmark end cap 1 and auxiliary end cap at the step gage two ends from external force collision longitudinally.Guardrail can form one-piece construction with pedestal, also can form removable or non-disconnectable the connection with pedestal.
