Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than the embodiment of whole.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
Fig. 1-2 is referred to, the present invention provides a kind of technical scheme：A kind of micrometer automatic reading device, including：Base 1,
Mechanical cover 2, rotary shaft 3, measuring head base 4, gauge head 5, motor 6.Mechanical cover 2, is arranged on the Far Left of base 1, described machine
2 bottom surface of tool shell is overlapped with the upper surface of base 1, and the outer surface of medial side face is overlapped with the left surface of base 1；Rotary shaft 3, if
Put inside mechanical cover 2, described 3 lower surface of rotary shaft is overlapped with the bottom surface of mechanical cover 2, described 3 upper end of rotary shaft
Face is overlapped with the top surface of mechanical cover 2；Measuring head base 4, is arranged in rotary shaft 3, and described 4 left-half of measuring head base is drilled with little
, there is screw thread in hole in hole, coordinate with 3 screw thread of rotary shaft, and the positive and negative rotation of rotary shaft 3 drives measuring head base 4 to move up and down；Gauge head 5, if
Put on measuring head base 4,3 gauge heads 5 are housed in the right half part of measuring head base 4,2, the right gauge head 5 of right half part is straight at one
On line, 1, left side gauge head 5；Motor 6, is arranged on 3 upper surface of rotary shaft, axle 3 is rotated and rotates；
Operation principle：First, micrometer is rotated, makes the gage button and micrometric screw of micrometer overlap.Micrometer is placed in into survey
5 underface.Motor 6 is opened, motor 6 is rotated axle 3 and rotates, and measuring head base 4 declines, just contact the bottom of gauge head 51
Contact with micrometer surface, stop motor 6 and rotate.The now left side and the micrometer microdrum of the contact gauge head 51 of left side gauge head 5
The right side overlaps.Micrometer microdrum is rotated, as when micrometer graduation mark is portrayed, groove part is to lower recess, so carving
There is obvious difference in height line part with non-groove part, and contact gauge head 51 can be moved up and down in inswept graduation mark, adjustable spring
52 stroke can change, and its changing value is passed to PC ends, and square wave figure occur in PC ends, according to square wave figure, using phase
Pass program, calculates the inswept scale number of lines of contact gauge head 51, and is multiplied by corresponding numerical value.Gather in microdrum graduation mark
In, as microdrum is to rotate, the cycle being there is, the cycle is 50 graduation marks, so calculating the total bar of last graduation mark
After number, by total number value divided by 50, its remainder is taken as first 2 of fractional part.The reading of micrometer is needed to last
Position decimal carries out estimating reading, and the length of last one end waveform is less than the length equal to same height waveform above, gathers last
Hold the length of waveform and above contrasted with the length of height waveform, calculate the ratio value that short-term section accounts for complete line segment, so as to
Judge fractional part last value.The right two gauge heads 5 collection is graduation mark in micrometer fixes sleeve, fixed cover
There are two row's graduation marks on cylinder, lower row is the integer part of scale value, its length change frequency is the numerical value of integer part.
When whether judging first decimal more than or equal to 5, the spring change frequency for calculating lower row is equal to upper row's spring change frequency, then
Show first fractional value more than or equal to 5, need fractional part first plus 5, conversely, then without.Final result is 3
The numerical value of decimal.So as to complete the automatic reading of micrometer.
This example completes the collection to graduation mark information using three gauge heads 5, has drawn numerical value by relative program, has subtracted
Manual operation is lacked.Whole assay device high degree of automation, personal error are little, and calibrating efficiency is high.Although having shown that and retouching
Embodiments of the invention are stated, for the ordinary skill in the art, it is possible to understand that in the principle without departing from the present invention
Various changes, modification, replacement and modification can be carried out to these embodiments with the case of spirit, the scope of the present invention is by appended
Claim and its equivalent are limited.
