Description

Soft electronic digital indicator
Technical field
The utility model belongs to dimensional measuring instrument technical field, specifically a kind of soft electronic digital indicator.
Background technology
In the industrial production, slide measure is mainly used in the straight length measurement of object, for example, workpiece diameter or external diameter Straight length measures;In addition, the blade of slide measure is generally the hard blade of inflexibility, not readily portable and keeping.When need When carrying out the measurement of the lengths of curve such as workpiece arc length, it can not be realized by the slide measure with hard blade.
Prior art such as discloses a kind of flexible vernier caliper in the utility model of Patent No. 201420641618.1, Can easily measuring part straight length or arc length.But the slide calliper rule disclosed in the patent use artificial reading, mistake be present Difference.And simultaneously because the blade of existing flexible vernier caliper is relatively thin, therefore general trip can not be used in flexible vernier caliper The module for marking slide calliper rule realizes digital display function.
Utility model content
The purpose of this utility model is to provide a kind of soft electronic digital indicator, solves the problems of the prior art.
The utility model adopts the following technical scheme that:Soft electronic digital indicator, including tape body and vernier, vernier are slided It is inserted in tape, one end of tape body is provided with fixation measuring pawl, slip measuring claw is provided with vernier, its technology will Point is:Fixed grid is provided with blade, fixed grid is the grid of the equidistant arrangement on blade;It is provided with the vernier relative with fixed grid The moving grid answered, the sensor for determining moving grid and fixed grid relative position and power supply, the signal transacting being connected with sensor Module and display module, digital display window and power switch are provided with outside vernier.
Further:The sensor is photoelectric sensor, including be arranged on fixed grid and moving grid both sides light source and with light Photoelectric cell corresponding to source.
Further:The sensor is capacitance sensor, including produces the crystal oscillator and receiving pole of clock signal.
Further:Locating piece is provided with fixation measuring pawl and slip measuring claw.
Further:The locating piece is magnetic patch.
Further:The back side on fixation measuring pawl and slip measuring claw is provided with subsidiary pawl.
The beneficial effects of the utility model are:The advantages of remaining existing flexible vernier caliper, digital display module is added, it is real Showed the function of digital display, not only can quick reading numerical values, while greatly avoid common slide calliper rule in reading process Subjective error.The blade of flexible any radian, blade length is any, and how long blade, which can all be coiled, when carrying or taking care of puts Put in box, it is extremely convenient;Using the blade of flexible certain radian make the utility model be not only able to measuring part internal diameter or External diameter isoline length and profiled parts arc length can be measured, expand application, at the same have in light weight, small volume, Easy to operate, low cost and other advantages.In addition, the utility model also has the advantages of accurate positioning, easy to use.

Embodiment
Embodiment 1:It is the soft electronic digital indicator of the utility model structure as Figure 1-3, including tape body 1 and trip Mark 2, vernier are slided and are inserted in tape, and one end of tape body is provided with fixation measuring pawl 3, and slip measurement is provided with vernier Pawl 4, technical points are:Be provided with fixed grid 5 on blade, fixed grid for the equidistant arrangement on blade grid, raster width with Spacing is identical;The moving grid 6 corresponding with fixed grid, the sensor for determining moving grid and fixed grid relative position are provided with the vernier 7 and the power supply 8, signal processing module 9 and the display module 10 that are connected with sensor, digital display window 11 is provided with outside vernier With power switch 12, power switch has zeroing function, power supply and sensor, signal processing module and display module electricity simultaneously Property connection, switch and power sources in series;It is additionally provided with yard and meter turn switch.The moving grid is the equidistant arrangement being arranged in vernier If dry lattice, it is corresponding with fixed grid, but its width and spacing are different from fixed grid.
Preferably:The sensor is photoelectric sensor, including be arranged on fixed grid and moving grid both sides light source 71 and with light Photoelectric cell 72 corresponding to source, when vernier moves relative to main scale, fixed grid and moving grid also relatively move, between corresponding each grid Produce periodically change.
Preferably:Locating piece 13 is provided with fixation measuring pawl and slip measuring claw, can conveniently be positioned.
Preferably:The locating piece is magnetic patch, mutual adhesive can be easy to take care of when slide calliper rule do not have to, can be with application Measured workpiece is held, is convenient for measuring.
Preferably:The back side on fixation measuring pawl and slip measuring claw is provided with subsidiary pawl, can be in measurement arc Workpiece is conveniently blocked during face, so that result is more accurate, the back side is behind relative digital display window accurate limit, in order between Observed data.
The measuring principle of the present embodiment is as follows, and in the present embodiment, the spacing between the raster width and grid of fixed grid is identical, Spacing between the raster width and grid of moving grid is also identical, but the difference of the raster width of moving grid and fixed grid, usually fixed grid 0.9 times of width, the quantity of the grid of fixed grid are no less than 10, so, when fixed grid and moving grid generation relative motion, grid Position produces relative motion, and then makes to produce different change through the light of grid, and photo-sensitive cell then receive these change into And corresponding signal input signal processing module is produced so as to draw the data of corresponding displacement, i.e. gained.
Embodiment 2:It is with the difference of embodiment 1, the sensor is capacitance sensor, including produces clock signal Crystal oscillator and receiving pole, crystal oscillator is equivalent to the light source for producing signal, and receiving pole is equivalent to the photosensitive electric device for receiving signal.
When before measurement, the utility model is taken out from box, the tape of coiling recovers straight in the presence of its own resilient Wire state, each measuring claw is wiped clean with soft cloth, close up fixation measuring pawl and slip measuring claw, turn on the power and return to zero i.e. It can start to measure, eliminate hand reset or keep the trouble of zero error in mind.When measuring profiled parts arc length, by fixation measuring pawl and Cambered surface top and end that measuring claw is stuck in profiled parts are slided, tape body is bent along extrados, you can according to digital display The display reading of window.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to In this, any one skilled in the art can readily occur in change in the technical scope that the utility model discloses Or replace, it should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with the power The protection domain that profit requires is defined.
