Abstract
The utility model relates to a raster encoder mechanism of an opto-isolator, which comprises a rotating shaft support, X and Y rotating shafts and roller wheels thereof. The raster encoder mechanism is characterized in that a large-diameter end of a step shaft is sleeved and fixed on the end portion of the X rotating shaft or Y rotating shaft while a small-diameter end of the step shaft is provided with a pressing sleeve, a raster encoder for holding and fixing is arranged between the pressing sleeve and a shaft shoulder of the step shaft, and the step shaft on the outer side of the pressing sleeve is provided with lock nuts which are in threaded connection and are tightly jointed with the pressing sleeve. The raster encoder mechanism of an opto-isolator leads the raster encoder to be separated from the X and Y rotating shafts, and is beneficial for circular raster encoders etched optical materials such as glass, resin or stainless steel to be applied to the opto-isolator. The raster encoder mechanism is also adaptable to track balls. In addition, the raster encoder mechanism has the outstanding advantages of increasing stability and anti-dust capacity of the opto-isolator obviously.
Description
Technical field
The utility model belongs to mouse, particularly relates to a kind of grating encoder mechanism of ray machine mouse.
Background technology
In the existing ray machine mouse, grating encoder is a wheeled construction, and promptly wheeled grating encoder and X, Y rotating shaft are moulded and be cast as one.Though above-mentioned wheeled grating encoder is simple in structure, is not suitable for and uses for example etched circular grating encoder of glass, resin or stainless steel of optical material.
Summary of the invention
The utility model is the grating encoder mechanism that a kind of ray machine mouse is provided in order to solve the above-mentioned technical matters that wheeled grating encoder exists in the existing ray machine mouse.
The utility model is taked following technical scheme for achieving the above object: this grating encoder mechanism comprises rotary shaft rack, X, Y rotating shaft and roller thereof, feature is, one multidiameter, big footpath one end suit also is fixed in X or the end of Y rotating shaft, path one end is provided with gland, be provided with the grating encoder that grips between the gland and the multidiameter shaft shoulder, the multidiameter in the gland outside be provided be threaded and with the locknut of gland fluid-tight engagement.
The utility model can also be taked following technical measures:
The diameter of described gland is corresponding with the center card of grating encoder.
The shaft shoulder of described multidiameter is provided with and the corresponding edge of gland.
Big footpath one end of described multidiameter is arranged with the jackscrew that is engaged in X or Y roller end.
The beneficial effects of the utility model and advantage are: the grating encoder mechanism of this ray machine mouse is separated grating encoder and X, Y rotating shaft, help optical material for example the etched circular grating encoder of glass, resin or stainless steel in the application of ray machine mouse.The utility model is equally applicable to trace ball.The utlity model has the stability and the obvious outstanding advantage that improves of anti-dust ability that make the ray machine mouse.
