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 description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.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 not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
Refer to Fig. 1-2, 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
Tool shell 2 bottom surface 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 rotary shaft 3 lower surface is overlapped with the bottom surface of mechanical cover 2, described rotary shaft 3 upper end
Face is overlapped with the top surface of mechanical cover 2；Measuring head base 4, is arranged in rotary shaft 3, and described measuring head base 4 left-half is drilled with little
Hole, in the hole has screw thread, coordinates with rotary shaft 3 screw thread, 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, measuring head base 4 right half part equipped with 3 gauge heads 5,2, 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 rotary shaft 3 upper surface, axle 3 is rotated and rotates；
Operation principle：First, rotate micrometer, so that the gage button of micrometer and micrometric screw is overlapped.Micrometer is placed in survey
5 underface.Open motor 6, motor 6 is rotated axle 3 and rotates, and measuring head base 4 declines, the bottom of contact gauge head 51 is just
Contact with micrometer surface, stop motor 6 and rotate.The now left side of contact gauge head 51 of left side gauge head 5 and micrometer microdrum
The right side overlaps.Rotate micrometer microdrum, because when portraying micrometer graduation mark, groove part is concave downward, so carving
Line part and non-groove part have obvious difference in height, and contact gauge head 51 can move up and down in inswept graduation mark, coil tension spring
52 stroke can change, and its changing value is passed to PC end, and square wave figure in PC end, 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.In the collection of microdrum graduation mark
In, because microdrum is to rotate, there is the cycle, the cycle is 50 graduation marks, so calculating the total bar of last graduation mark
After number, by total number value divided by 50, take its remainder as first 2 of fractional part.The reading of micrometer needs to last
Position decimal carries out estimating reading, and the length of last one end waveform is less than being equal to the length of same height waveform above, gathers last
The length of end waveform with above contrasted with the length of height waveform, calculating short-term section accounts for the ratio value of complete line segment, thus
Judge last value of fractional part.What two, the right gauge head 5 gathered is the graduation mark in micrometer fixes sleeve, fixed cover
Two row's graduation marks are had, lower row is the integer part of scale value, its length change frequency is the numerical value of integer part on cylinder.?
When whether judging first decimal more than or equal to 5, the spring change frequency calculating lower row is equal to upper row's spring change frequency, then
Show that first fractional value is more than or equal to 5, need for fractional part first to add 5, conversely, then without.Final result is 3
The numerical value of decimal.Thus completing 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
Lack manual operation.Whole assay device high degree of automation, personal error is 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
Multiple changes, modification, replacement and modification can be carried out with the case of spirit to these embodiments, the scope of the present invention is by appended
Claim and its equivalent limit.
