Abstract
The utility model relates to a dynamic grating for manual pulse generator, in particular to a device applied to various rotary encoders as one of the most important parts. The circumference of the dynamic grating body is evenly distributed with a plurality of groups of grating lines. The utility model is characterized in that: the circumference of the dynamic grating body is provided with a location hole and location combined holes. The structure of the utility model is simple, compact and reasonable; the utility model has the function of self location of the circle, the position of X axis and Y axis can be accurately located by two holes or combination of a plurality of holes, which makes up the shortages that no reference hole is arranged in the past or the combination of the reference holes can only locate one direction; since the layout work applies novel and efficient optoelectronic device with high integration, the spatial phase separation arrangement and a reading system of multiple read head are designed, thus effectively prolonging the service life of the whole rotary encoder.
Description
Technical field
The utility model relates to the moving grating of a kind of manual impulsator, specifically is applied on the various rotary encoders, and be one of topmost parts of rotary encoder.
Background technology
The moving grating of manual impulsator is mainly used in rotary encoder, utilizes common moving grating to cooperate with common quiet grating and produces the optical gate effect.In prior art, because common moving grating and common quiet grating do not have datum hole or datum hole combination when design, the manufacturability that the sound grating cooperates in producing assembling is poor, consistance is poor, do not produce high-quality optical gate effect, thereby forms shortcomings such as the rotary encoder stable output signal is poor, consistance difference.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of manual impulsator to move grating, does not have datum hole or datum hole combination can only locate the deficiency of a direction before having remedied; The space phase-splitting is arranged, and the frame of reference of bull reading can effectively prolong serviceable life of whole rotary encoder.
Main solution of the present utility model is achieved in that
The utility model mainly adopts on moving grating body circumference and is shaped on uniform grid line, and feature is to be laid with pilot hole and location combination bore on the described moving grating body circumference.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; It has the self-align function of circumference, utilizes the combination of two holes or porous can accurately locate the position of X and Y-axis, does not have datum hole or datum hole combination can only locate the deficiency of a direction before having remedied; Since the layout fit applications novel, efficient, high integration photoelectric device, designed the space phase-splitting and arranged, the frame of reference of bull reading can effectively prolong serviceable life of whole rotary encoder.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The moving grating body 4 of the utility model adopts as thin as a wafer metal disk or plastics disk to make, and is shaped on uniform a certain proportion of grid line 1 on moving grating body 4 circumference, is laid with pilot hole 2 and location combination bore 3 on described moving grating body 4 circumference.Location combination bore 3 is that grid line 1 forms the location combination with pilot hole 2.Grid line 1 above the moving grating body 4, pilot hole 2 and location combination bore 3 all design by scientific and reasonable computing, lines are placed according to specific design value and design attitude, and pattern grid line 1, pilot hole 2 and combination bore 3 places, location all have certain position relation.
The syntagmatic at the utility model place, it has the self-align function of circumference, utilizes the combination of two holes or porous can accurately locate the position of X and Y-axis, does not have datum hole or datum hole combination can only locate the deficiency of a direction before having remedied.
Claims (2)
