Abstract
A digital readout optical grating height gauge adopts an optical grating gauge as a displacement sensor, a height gauge mechanical structure of the digital readout optical grating height gauge comprises a base, a main gauge, a sliding seat, a gear, racks, a hand wheel, a fine tuning nut, a lock screw and the like, an optical grating gauge is assorted and used as a displacement detection sensor, and an LED digital readout instrument is used to display measuring results. The digital readout optical grating height gauge is mainly used for precious measurement of height dimensions of mechanical parts.
Description
Technical field
The utility model relates to and being applied in the machine-building, a kind of height gauge of measuring workpieces height dimension, and it is used to be particularly useful for measuring the part height dimension on the platform.
Background technology
At present, known height gauge has two kinds of groove formula, digital display types.The groove formula is with to line formula reading, and error is bigger; Digital display type adopts displacement sensor of variable capacitor, liquid crystal digital count table to show reading mostly, and reading error directly perceived is less.
More than two kinds of height gauges, use in the higher measurement of precision prescribed, feel that degree of accuracy is not high enough, slightly sense inconvenience of observed reading in darker environment.
Summary of the invention
In order to remedy the weak point of above height gauge, improve the precision of ruler self, the utility model adopts a kind of digital display grating height gauge, realizes that the height of degree of precision part is measured, and observed reading is not subjected to the influence of ambient brightness easily.
The technical method that its technical matters that solves the utility model adopts is: adopt the displacement transducer of digital display grating chi as measuring height, adopt the LED digital display meter to show measurement result.Physical construction is similar to common height gauge, and different is to have increased a cover tooth bar, gear drive.Tooth bar is fixed on the main scale blade, gear is assembled on the slide, gear is connected one with handwheel, rotating handwheel rotates gear, by the gear motion of rack-and-pinion, can realize moving up and down of slide, drive the grating ruler reading head that is fixed on the slide and move, form displacement signal with the grating chi that is fixed on the main scale, be transferred to the LED digital display meter and show displacement numerical value.Slide is divided into big or small two parts, and lock-screw is respectively arranged, and can slide be fixed in the main scale optional position.One cover spiral micromotion mechanism also is housed between two slides, regulates fine-tuning nut and can realize that the trace of slide moves, drive read head and the displacement at a slow speed of grating chi, reach the purpose of pin-point reading.This digital display grating height gauge adopts the rectifier power source low-voltage power supply, saves the trouble of changing battery.
The beneficial effects of the utility model are: adopt the grating chi as displacement transducer, and the precision height, the source is wide, technology maturation.Adapted LED digital display meter shows reading, and is limpid in sight, and not influenced by ambient brightness, and personnel observe easily, and measurement result does not have dispute.The measuring accuracy of device depends primarily on grating chi and the digital display meter precision that is adopted, and physical construction is simple, and is easy to manufacture, is suitable for popularization.
