Description
Technical field
The invention belongs to engineering survey field, it is related to a kind of digital display type slide calliper rule.
Background technology
Electronic digital indicator has some advantage relative to traditional slide measure：
1st, the reading that digital displaying function greatly avoids the observation problem of human eye from causing is forbidden.
2nd, metric system translation function made in Great Britain greatly saves our Extrapolation times in measurement process.
3rd, reading lock function is even more to facilitate our survey measurements.
All it is the advantage that traditional slide measure can not compare above, but electronic digital indicator also has scarce by comparison
Point：
1st, the measurement accuracy of electronic digital indicator is not so good as traditional slide measure.Because mechanical structure is not quite similar, typically
Old-fashioned slide measure can easily accomplish 0.02mm precision, and general electronic digital indicator is extremely difficult to.Digital displaying callipers
The average precision of chi typically is in more than 0.03mm, but general traditional slide measure precision with mechanical gauge outfit can very easily
Reach 0.01mm.
2nd, need to change battery.This is slide measure as an inevitable shortcoming of electronic product, certainly with
Development in science and technology in recent years, the birth of solar energy electronic digital indicator also allows this to become the past.
3rd, water stain spot is becomed easily infected by, so as to cause reading to be forbidden.Compared to traditional slide calliper rule, the measuring circuit of digital display calliper by
Ambient influnence is larger, although with the development of technology, occurs in that the digital display calliper of water slug anti-to a certain degree, but former with regard to its measurement
Reason, this kind of influence can not still be eliminated.
The content of the invention
In view of this, can be in traditional slide measure base it is an object of the invention to provide a kind of digital display drum type brake slide calliper rule
Real-time observable is realized on plinth；Solve that universal digital display slide calliper rule are easily intake, fixed grid is easily influenceed so as to causing digital display to ask by spot
Topic.
To reach above-mentioned purpose, the present invention provides following technical scheme：
A kind of digital display drum type brake slide calliper rule, including shell and main scale, pair of nut, leading screw, bearing block, depth gauge rule, internal measure-hand,
Exterior measuring measuring jaw, increment of rotation formula encoder, display screen, pulse counter circuit board, the leading screw are compiled installed in increment of rotation formula
On code device, by bearing block axially position, the pair of nut is connected with leading screw, the movable claw and depth gauge rule of inside and outside measuring claw
Difference attaching nut's pair；The linear motion of pair of nut drives leading screw to produce rotary motion, and the rotational movement rotation of leading screw increases
Amount formula encoder produces pulse electrical signal and passes to pulse counter circuit board, passes through mcu programming, connection display screen response.
Further, there is scale on the shell and main scale, artificial rough reading can be passed through.
Further, the pair of nut is provided with a vernier, can pass through artificial pin-point reading.
Further, the movable claw of the depth gauge rule and internal measure-hand is structure as a whole.
Further, the leading screw is ball-screw, and the pair of nut is ball guide screw nat.
Further, the leading screw is connected by spring housing, recoverable capsule, ball and pair of nut.
Further, the shell and main scale are cylinder type.
The beneficial effects of the present invention are：
1st, the input of air line distance is changed into rotating signal and gives electronic section by mechanical part using ball-screw as core
Counted.For traditional digital display calliper structure more accurately and reliably, ball-screw revolves for the design of this mechanical structure
Rotaring signal will not be affected for the capacitive grating transducing signal of traditional digital display calliper because spot is water stain, the circle of this patent
Barrel structure, and overall arrangement also make it that ball-screw is difficult to be infected by spot, the fabulous service life that ensure that instrument.
And with the progress of manufacturing process, the precision of this patent can also be improved therewith.
2nd, the core of electronic section is increment of rotation formula encoder., can be by increment of rotation formula by the programming of single-chip microcomputer
The pulse signal of encoder is converted into data signal and shown in display screen.Due to programmable reason, feature will
Become variation, such as data interlock function, metric system translation function made in Great Britain, function of solar charging even data transfer or point
Function is analysed, or is that the development that PLC high-speed counters are miniaturized can lift portability and accuracy, more utility functions can
It is accomplished on algorithm and hardware, so this patent scheme can be correspondingly improved with the development of technology, so as to have
Sustainable development space.
