Abstract

The utility model discloses a raster-based novel high-precision height gauge and relates to a measuring instrument. The raster-based novel high-precision height gauge comprises a pressure plate, guide pillars, a high-precision linear displacement reading head, a display panel, a measuring jaw, a locking frame, a ruler seat and a protective cover, wherein the upper ends of the guide pillars are connected with the pressure plate and the lower ends of the guide pillars are connected with the ruler seat so as to form a main body of the height gauge, a high-precision raster is disposed between the guide pillars and has an upper end connected with the pressure plate and a lower end connected with the ruler seat, and the measuring jaw is connected with the display panel through the locking frame and moves up and down according to the height of a measuring object so as to drive the display panel to move up and down on the high-precision raster, thereby realizing accurate reading. The raster-based novel high-precision height gauge has the following advantages: on the basis of raster measuring principle, high precision measuring is realized; through the development of an intelligent calibration technology, high efficient and high precision detection is realized; by use of a wireless signal transmission technology, high precision on-line detection is realized; and by use of a housing made of a high-quality jam-proof material, the detection stability is improved.

Description

A kind of novel high-precision height gauge based on grating
Technical field
The invention belongs to advanced manufacture field, be widely used in the high-acruracy survey of the industries such as ultra-precision machine tool, automobile, Aero-Space, photoelectron.
Background technology
Along with advanced manufacturing technology is fast-developing, especially have higher requirement to the accuracy of form and position of mechanical component and optical element more than manufacturing accuracy has been risen to 5 μ m magnitudes in the fields such as ultra-precision machine tool, automobile, Aero-Space, photoelectron.Therefore carry out the high precision size and shape Research on measuring technique towards manufacturing industry workshop aspect, not only there is important theoretical significance, and to promote China's manufacturing industry field test level, improving the quality of products has larger using value.
Current external machine-building workshop rare processing and accuracy of detection to 10 μ m levels to the utmost, the horizontal Foundation of machining precision in its most of workshop is more than 5 μ m, and this is also the main cause that foreign-made technical merit is high.And domestic high precision measuring instrument be take import as main at present, and expensive, seriously restricting the development in an all-round way of China's manufacturing industry, therefore, development high precision detecting instrument is extremely urgent.
Summary of the invention
For a kind of high precision height-gauge device is provided, this is novel provides a kind of novel high-precision based on grating
Height gauge, easy to operate, meet the demands.
High precision height gauge comprises pressing plate, guide pillar, high-precision wire displacement transducer, display panel, measuring claw, locking frame, rod support and protective cover, guide pillar upper end is connected with pressing plate, lower end is connected with rod support, height of formation chi main body, high precision grating is between two guide pillars, upper end is connected with pressing plate, lower end is connected with rod support, measuring claw is connected with display panel by locking frame, according to the height of measuring object, measuring claw moves up and down, thereby drives display panel to move up and down at high precision grating, thereby realizes pin-point reading.
High precision height gauge innovative point: the measuring principle based on grating, realizes high precision and detects; The exploitation of intelligence collimation technique, realizes efficient, high precision detection; Wireless signal transmission techniques, realizes high precision and detects online; Adopt the anti-tampering material shell of high-quality, reduce external interference, improve and detect stability.
