Description
Technical field
The utility model relates to grating scale, is convenient to the fine tuning structure of the grating scale eliminating the error that component tolerances causes when refering in particular to a kind of installation.
Background technology
Along with the development of science and technology, the accuracy of electronic component improves constantly, generally grating scale is used in made with high precision industry, but in the production run of grating scale, be bound to there is inevasible tolerance, especially the aluminium section bar slide rail of grating scale is, in current grating scale production and assembly process, substantially all on aluminium section bar, grating scale is compressed with press strip, and then fix with glue, this production method is the error cannot improved because the component tolerances such as glass raster or aluminium section bar slide rail cause, if only eliminate this tolerance from part, very difficult when the grating scale of production degree of precision, in addition, this grating displacement sensor is in the process of Long-Time Service, use 5 transmitting illuminants and 5 photosensitive tubes, the corresponding photosensitive tube of each transmitting illuminant, because after 5 transmitting illuminant Long-Time Service, brightness is inconsistent, this not only can affect grating sensor measuring accuracy, and also have and leak the countless risk of number and its cost is high, practicality is poor.
Summary of the invention
In order to solve the problem, the utility model aims to provide a kind of grating scale, is convenient to the grating scale fine tuning structure eliminating the error that component tolerances causes when refering in particular to a kind of installation.
Realize above-mentioned purpose, the technical solution adopted in the utility model is: a kind of fine tuning structure of grating scale, comprise slide rail and be slidably mounted in the testing agency on described slide rail, described slide rail is provided with several adjustment holes, adjustment hole described in several is provided with adjusting screw, described testing agency is provided with single luminotron and several photosensitive tubes, and described luminotron is electrically connected with photosensitive tube described in several respectively.
Wherein, the bottom of described slide rail inside is provided with groove, is arranged in the groove of described slide rail to described adjustment hole array, and described adjustment hole runs through the bottom of described slide rail and is a lineal layout.
Wherein, described adjusting screw is butted on erecting bed through described adjustment hole, and is fixedly installed on by binding in the groove of described slide rail.
Wherein, described single luminotron is connected in series with described photosensitive tube respectively and forms overall metering circuit, and described luminotron is LED light emitting diode or HF lamp without electrodes.
The beneficial effects of the utility model are presented as: the utility model aims to provide a kind of fine tuning structure of grating scale, by with the addition of adjustment hole bottom aluminium section bar slide rail, and adjusting screw is put in adjustment hole, coordinate the error information of grating sensor on laser length measuring machine, the position of adjusting screw, its precision is made to reach Production requirement, with glue, adjusting screw and glass are fixed again, change multiple light source into an irradiated area large transmitting illuminant simultaneously, it is simple that the inconsistency allowing luminotron cause reduces its structure, production cost is reduced while meeting accuracy requirement, practical.
