Description
Technical field
This utility model relates to machinery industry detection equipment making correlative technology field, refers in particular to a kind of narrow
Machining long workpieces Instrument for Straightness structure.
Background technology
Magnetic industry Magnetic shoe gridner process in, guide rail, R plate use widely.This workpiece master
If play conveying and guide effect when grinding magnetic shoe product, its major requirement be linearity, hardness with
And the requirement of wearability.Due to higher to itself hardness requirement, typically require material 60HRC with
On.At present, a lot of enterprises are also using box heat treatment furnace to carry out heat treatment, this heat treatment mode pair
The technology of operator requires at a relatively high, and heat treatment stability is poor, the workpiece hardness of heat treatment is uneven,
Fatigue resistance is low, easy to crack, particularly as the long and narrow workpiece of guide rail, R plate class is in heat treatment process
Easily causing deformation, the linearity of workpiece is overproof very big, brings many difficulty to the processing of postorder.Again
Either large or small Geometrical Error can be produced in the postorder course of processing plus part, these errors
There is the total quality that not only can affect engineering goods；More can affect interchangeability and the serviceability of parts.
Using widely at mechanical field cathetus degree detection equipment, the method for measurement is a lot, such as: cutter
Bicker chi and ruler measurement method, level measurement, three-dimensional coordinates measurement, optical alignment telescopic system is utilized to survey
Amount, the measurement of optical autocollimating method, micrometry, pitch order, data collecting instrument connect dial gauge method, straight line
Method measures linearity etc..Further, it is also possible to utilize optical flat, laser interferometer and straight line degree measurement thereof attached
Part measures straightness error.
The most all, different parts, the ways and means of its measuring straightness error is not quite similar,
But there is it for measuring the guide rail of use, the linearity of R plate in magnetic industry grinding machine processing magnetic shoe product
Not foot point:
1, knife edge angle square and ruler measurement method: this method is often through the method for printing opacity, by element to be measured
Being compared to measure with ideal factor, advantage is to measure simply, but more seldom goes out concrete measurement number
Value.
2, level measurement: the flatness and linearity, the equipment that are mainly used in lathe kind equipment guide rail are installed
Horizontal level and upright position etc..
3, three-dimensional coordinates measurement: very accurate, but equipment investment is big.
4, optical alignment telescopic system is utilized to measure straightness error: this collimating telescope can be used for measuring
The coaxiality error of each support holes on heavy-duty machines (such as steam turbine)；Optical autocollimating method auto-collimation
Instrument is measured, and tested total length is divided into some sections, measures the inclination angle of each section, then by mapping or calculating
Obtain linearity.
5, micrometry: for measuring cylinder voxel line or the linearity of axis.
6, pitch order: be applicable to the measurement of elongated workpieces, is divided into some segments by measured length, uses level
The relative reading of each section measured by instrument, autocollimatic instrument etc., processes finally by data and obtains straightness error.
7, data collecting instrument connects dial gauge method: although the method can calculate straightness error value automatically,
But it is in the majority to be mainly used in axial workpiece.
8, straight-line method: utilize steel wire and laser beam etc. to measure linearity.
Can be seen that from above-mentioned verticality measuring method, knife edge angle square and ruler measurement method, three coordinates are surveyed
Amount is relatively suitable for the guide rail described in literary composition, the measurement of R plate, knife edge angle square and ruler measurement method measure simple,
Convenient, but more seldom go out concrete measurement numerical value；Although three-dimensional coordinates measurement is very accurate, but equipment investment
Greatly.
