Abstract
The utility model discloses a measuring mechanism for a combined laser guide screw measuring instrument, comprising a bed body, a bed head box arranged on one end of the bed body, a circular grating angle standard measuring system arranged on the bed head box and a tailstock arranged on the guideway on the bed body. A measured lead screw can be fixed between the bed head box and the tailstock; the guideway is provided with a workbench; the workbench is provided with a locating contact head pointing to the pitch diameter point of the lead screw and a laser retroreflector which is arranged after the tailstock; the other end of the bed body is provided with a laser interferometer; a laser generator is arranged beyond the bed body. The utility model can be used as a laser index head and a laser length measuring machine, according with the 'abbe principle'. The utility model has the advantages of high accuracy, strong adaptability and low cost.
Description
The utility model relates to a kind of taking measurement of an angle simultaneously and the measuring mechanism of measurement of length instrument.
Putting down in writing the vertification regulation of " laser leading screw dynamic measuring instrument " on People's Republic of China's " national metrological verification regulations compilation " length (seven) that China Measuring Press publishes, the institution of higher education that the visible China Machine Press of its measuring principle publishes teaching material on probation is by " geometric sense metering " P293 the 6th joint " measurement of helix error " of the yellow clear canal chief editor of Harbin Institute of Technology.But this instrument has following shortcoming: 1. length metering standard and angular measure standard knots are closed as a wholely, can not independently exercise function of measuring separately, thereby measurement function is single, and performance, price lower, the general user cannot afford.2. the length range of measuring leading screw has only a kind of, and corresponding with it, measuring accuracy also has only a grade, thereby is subjected to certain restriction on range of application.3. owing to structural reason, instrument available does not meet " abbe ' s principle " (seeing " geometric sense metering " P7 " cardinal rule of measurement "), promptly because the laser retroreflector is located at the radial side of tested leading screw, so in measuring error, increased the error of a guide rail, thereby the precision of measuring is restricted.4. instrument adopts the single-frequency laser interference system, measurement environment condition and electric property are had relatively high expectations, thereby the adaptability of instrument is relatively poor.
The purpose of this utility model is: use a kind of both capable of being combined is provided, can uses separately separately again, two kinds of linear measure longimetry scopes are arranged, precision meets " abbe ' s principle ", the measuring mechanism of the combined laser lead screw measuring instrument that environmental suitability is stronger.
The technical solution of the utility model is: a kind of measuring mechanism of combined laser lead screw measuring instrument, comprise lathe bed, place selective headstock, the selective headstock side of lathe bed one end to be provided with round grating angular standard amount system, to place the tailstock on the bed ways, can fix tested leading screw between selective headstock and the tailstock, guide rail is provided with worktable, worktable is provided with the positioning contact and the laser retroreflector at finger place, footpath in tested leading screw, described laser retroreflector places after the tailstock, the other end of described lathe bed is provided with the laser interference device, is provided with laser generator outside the lathe bed.
The utlity model has following advantage:
1. owing to returning body device, laser interference device and laser generator, laser all is located on the extended line direction of tested leading screw axis, measuring principle meets " abbe ' s principle ", can realize a kind of high-acruracy survey of range, if tailstock is moved to the end of lathe bed, and the laser retroreflector placed on the worktable in the middle of the round grating angular standard amount system, then can realize the measurement of the lower accuracy of times range.
2. utilize the round grating angular standard amount system and the tailstock of instrument, can constitute general dividing head uses, change special-purpose worktable and annex and also can be used as general gauging machine use, laser retroreflector and the loading and unloading of laser interference device are easy to adjust, can also independent use, the module combinations that has realized various measurement functions with cut apart.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a front view of the present utility model;
Fig. 2 is a vertical view of the present utility model.
Wherein: 1. tested leading screw; 2. tailstock; 3. laser retroreflector; 4. laser interference device; 5. laser generator; 6. worktable; 7. lathe bed; 8. justify grating angular standard amount system; 9. positioning contact; 10. bed ways; 11. selective headstock; 12. rectangular opening.
By Fig. 1,2 as can be known: a kind of measuring mechanism of combined laser lead screw measuring instrument, comprise lathe bed 7, place the selective headstock 11 of lathe bed 7 one ends, selective headstock 11 sides are provided with round grating angular standard amount system 8, place the tailstock 2 on the bed ways 10, can fix tested leading screw 1 between selective headstock 11 and the tailstock 2, guide rail 10 is provided with worktable 6, worktable 6 is provided with the positioning contact 9 and the laser retroreflector 3 at finger place, footpath in tested leading screw 1, described laser retroreflector 3 places after the tailstock 2, the other end of described lathe bed 7 is provided with laser interference device 4, is provided with laser generator 5 outside the lathe bed 7.Described laser retroreflector 3, laser interference device 4 and laser generator 5 are all on the axis extended line direction of tested leading screw 1.There are a rectangular opening 12, tailstock 2 to place in the middle of the rectangular opening 12 in the middle of the described worktable 6.The principle that measuring instrument generates based on the leading screw helix, with optical maser wavelength as the length metering standard, the circle grating is as the angular measure standard, laser and grating signal with output synchronously, be received by the receiver, the error of kinetic measurement leading screw helix, and by registering instrument draw automatically helix graph of errors or get measurement result.During work, selective headstock 11 drives tested leading screw 1 and rotates, worktable moves right by pitch, the angle that tested leading screw 1 rotates is measured by circle grating angular standard amount system 8, positioning contact 9 refers to the place, middle footpath at tested leading screw 1, the displacement of positioning contact 9 is reflected synchronously by the laser retroreflector 3 on the worktable, and the laser retroeflection through laser interference device 4 that laser generator 5 sends is come out, and is received by the receiver.Because laser returns body device 3, laser interference device 4 and laser generator 5 and all is located on the extended line direction of tested leading screw 1, measuring principle meets " abbe ' s principle ", realized a kind of high-acruracy survey of range, if tailstock 2 is moved to the end of lathe bed 7, and laser retroreflector 3 placed on the worktable 6 in the middle of the round grating angular standard amount system 8, then can realize the measurement of the lower accuracy of times range.Utilize the round grating angular standard amount system 8 and the tailstock 2 of measuring mechanism, can constitute general dividing head uses, change special-purpose worktable and annex and also can be used as general gauging machine use, laser retroreflector 3 and 4 loading and unloading of laser interference device are easy to adjust, can also independent use, the module combinations that has realized various measurement functions with cut apart.
