Abstract
The utility model relates to a fixing device for optical grating scale, belonging to a element of optical grating scale. The one inner is connected with a long optical grating wall square groove in the optical grating aluminum case. A polyurethane high elastic of 2 to10 sections is arranged in this square groove. The utility model is characterized in new type structure and make use of polyurethane elastic to compress the long optical grating in a square groove in aluminum cable, and the long optical grating will not generate over large installation stress and stress concentration with easy operation for large scaled industrial production.
Description
Technical field
The utility model belongs to grating chi parts, is applied to be used for detection of straight lines length in the equipment such as lathe.
Background technology
In the fixed sturcture design of grating footage number chi grating, because the irrationality of design can make the scale grating produce the phenomenon that erection stress is big or stress is concentrated, in the middle of the use of grating chi, can make the scale grating produce stress cracking, influence the quality of grating chi.
Summary of the invention
The utility model provides a kind of grating footage number chi grating stationary installation, with the problem that erection stress is big or stress is concentrated in the fixed sturcture that solves grating footage number chi grating.The technical scheme that the utility model is taked is; The bonding long grating 2 of a sidewall in the square groove of grating chi aluminium box 1 is closely placed 2～10 sections high elastic polyurethane bodies 3 in this square groove.
The utility model advantage is; Novel structure utilizes the high elastic polyurethane body to compress the interior long grating of aluminium box square groove, makes long grating not produce excessive erection stress and stress concentration phenomenon, and is simple to operate, reliable in the practical set process, is convenient to big suitability for industrialized production.
