Abstract
The utility model relates to a floatable indicative optical grating, belonging to optical grating range. A glass carrier of indicating optical grating 1 is connected with Teflon coating 2 which is one surface together with the indication optical grating patter. The advantage is that new type structure is used. When Teflon coasting is sliding on scale grating, the gap between indicating optical grating and scale optical grating is adjustable due to adjustable thickness of Teflon coating; and due to the self-lubricated and wearable feature of Teflon coating, the utility model is able to replace 3 bearing on position surface of 5-bearing floating bearing system, generally-used 5-bearing floating shaft system in reading head design of optical grating can be changed into 5-bearing flowing shaft system to simplify reading head design and reduce part process difficulty and cost.
Description
Technical field
The utility model belongs to a kind of grating, is applied to be used for detection of straight lines length in the equipment such as lathe.
Background technology
The normal five bearing floating axles system that adopts in the design of the read head of grating chi, above bonding indication grating.Because designing requirement, indication grating and scale grating will guarantee extremely small gap in assembling, and this brings big difficulty for the manufacturability of assembling, has increased the part processing difficulty.
Summary of the invention
The utility model provides a kind of indication grating that floats, to solve the problem that difficulty is adjusted in present indication grating and scale grating gap.The technical scheme that the utility model is taked is: indication grating glass carrier 1 is fixedlyed connected with teflon coatings 2, and this teflon coatings 2 and this indication grating pattern are on a face.
Advantage of the present utility model is: novel structure, when teflon coatings slides on the scale grating, because the thickness of teflon coatings is adjustable, make indication grating and scale grating adjustable gaps, again because profit, wear-resisting characteristics certainly that teflon coatings has, three bearings of the locating surface that alternative five bearing floating axles are, can change the normal five bearing floating axles system that adopts in the design of the read head of grating chi into two bearings floating axle system, simplify the read head design, reduce the part processing difficulty and then reduced cost.
