Abstract
The utility model discloses a multipurpose optical grating measuring apparatus, and the utility model has the key that a magnet base is arranged on the body of the measuring apparatus; an optical grating and a spring for measuring force are directly arranged on a cylindrical length rod which is also used as an optical grating lead rail; a photoelectric reader adopts miniature lamps and a short focal distance cylindrical mirror for lighting, wherein, the back of the short focal distance cylindrical mirror is frosted; a four-crack indication grating provides sine signals and cosine signals, wherein, the fixed phase of the four-crack indication grating differs for 90 DEG; the signals are connected and enlarged by phototransistors, and then are converted to electrical signals to output. The utility model reduces volume and achieves the purposes of flexible usage.
Description
The utility model relates to a kind of length-measuring instrument, particularly a kind of multitask grating measuring instrument.
Known grating length gauging instrument is because the selectivity of its structural design can only be used in certain stationary applica-tions usually.For example, the pattern displacement device that uses on the lathe can only be fixed on certain lathe and use, and vertical grating-measurer can only use in measuring room, this shows that their versatility is poor, and utilization factor is lower.
The purpose of this utility model is to provide a kind of highly versatile at above-mentioned weak point of the prior art, the multitask grating measuring instrument that utilization factor is high, not only volume is little for it, be suitable for being fixed on the measurement of making any duty on all kinds of lathes, but also can relevant instrument connection with other be used in combination.
Technical solution of the present utility model is: 1. a magnet base is set on the grating measuring instrument.2. grating and dynamometer spring are set directly on the cylinder measuring staff, cylinder measuring staff double as grating guide rail is used.3. several pea lamps are set in photoelectric reader, and grating equably throws light on behind the short focal length cylindrical mirror collimation of the light source that is produced via back side frosted.
Accompanying drawing by the following examples is described in further detail the utility model.
Fig. 1 is the structural representation of multitask grating measuring instrument;
Fig. 2: A-A is to sectional view among Fig. 1.
In the present embodiment, magnet base (7) can connect with the measuring instrument body or take off easily by metal fastenings.Measuring staff (1) is cylindrical, and it is to do to seesaw by the ball bearing that places two ends (2) guiding.The ball bearing at two ends is three respectively, is distributed on the periphery of measuring staff (1).Grating (4) is arranged in the measuring staff, and the grating face overlaps with the axial line of measuring staff and be parallel with cylindrical mirror (5).In order to prevent the measuring staff rotation, play a part to clamp and guiding at latter half of two parallel planes (11) ball bearing (9) that are provided with respectively of measuring staff (1).Dynamometer spring (8) is arranged in the bottom and pedestal (3) of measuring staff (1).Be provided with 4 pea lamps (10) in the photoelectric reader of present embodiment, when throwing light on grating equably behind short focal length cylindrical mirror (5) collimation of the light source that is produced via back side frosted, and by four split phase indicative gratings (6) of 90 ° of fixed skew just providing, cosine signal, convert electric signal output to through the phototriode amplifying circuit that constitutes in parallel again, technology is provided with a numeric display unit (adding charactron as chip driver shows) routinely simultaneously, can directly make numeral and show.
The utility model has following advantage compared to existing technology:
1. the utility model volume is little, and magnet base arranged, thereby convenient fixing, it can be installed on different lathes and the different parts easily according to need of work, can solve amesdial, torsion spring instrument, lever comparator etc. needs the slip gauge spreading to carry out the needs of measurement size or lathe location owing to range is short, its applicability is strong, thereby can greatly reduce the equipment investment expense.
2. the utility model is contained in the use that can make gauge on the flat board, increases connector, can make standarized component, as required, and can vertical or horizontal use, also use capable of being combined.
Claims (3)
1, a kind of grating measuring instrument, be made up of measurement mechanism, photoelectric conversion device, amplifying circuit and numeric display unit, it is characterized in that the column type measuring staff of measurement mechanism is provided with a grating, the grating face is positioned on the axial line, simultaneously, the body of measuring instrument is provided with magnet base.
2, according to the grating measuring instrument of claim 1, it is characterized in that respectively being provided with three ball bearing at two supported ends of column type measuring staff, the rear portion of measuring staff is provided with two parallel surfaces, and dynamometer spring is equipped with in the measuring staff bottom.
3, according to the grating measuring instrument of claim 1 or 2, it is characterized in that photoelectric conversion device by a plural pea lamp and a back side sanding and be parallel to the cylindrical mirror that grating pays and form, is provided with four split phase indicative gratings and the phototriode in parallel of 90 ° of fixed skew simultaneously.
