Technical field
The utility model is related to height gauge technical field, more particularly to a kind of high-precision digital-display height gauge.
Background technology
Height gauge is the conventional instrument of field of machining, is mainly used in measuring the height of workpiece, is also frequently used for measurement
Geometrical and toleranging size, it can also be used to rule.Height gauge passes through handwheel conditioning box during measurement height use, generally
The position of frame, so as to drive line pawl to rise or fall, when reaching testee surface, now draws reading for testee
Highly.
But height gauge is in height measurement process, it is typically only capable to rely on when contacting with testee surface due to pawl of ruling
Naked eyes go to see whether contact, or judge to rule by the impression resistance that is subject to of line pawl during hand wheel rotating pawl whether with it is tested
Object is contacted, and so in measurement process, can bring larger error.Only rely on naked eyes, it is impossible to it is determined that whether now ruling pawl
Contact with testee, especially when testee surface is relatively low, people need viewing of bending, and more improve the mistake of reading
Difference；And relying on line pawl stressing conditions to judge whether line pawl contacts with testee surface increases can error, because object
Generally there is its ductility, can so make measurement result less than normal.Accordingly, it is now desired to one kind can conveniently learn line pawl measurement process
In whether the height gauge contacted with testee improving certainty of measurement.
Utility model content
The purpose of this utility model is for the not high problem of present level chi certainty of measurement, there is provided a kind of high-precision digital-display
Height gauge.
A kind of high-precision digital-display height gauge, including height gauge body, the height gauge body include base, count tooth bar,
Driving rack, framework, handwheel, line pawl and locking system, the counting tooth bar is parallel with driving rack, the counting tooth bar and
On the base, the frame hub is counted on tooth bar and driving rack driving rack mounted perpendicular located at described, the handwheel
It is installed on the framework, the line pawl is fixed at the framework side, and the locking system is installed in the framework
Top, the height gauge body also includes the smooth sensor block in a lower surface, and the lower portion is provided with sensing and shows mould
Block, the sensor block is electrically connected with the sensing display module, and the sensing display module includes processor and display, described
Line pawl lower surface is equiped with inductor, and the inductor is connected with the sensing block signal.
Wherein in one embodiment, vernier scale and display screen, vernier scale and the counting tooth are equiped with the framework
Bar sliding contact, is provided with travelling gear in the framework, the handwheel is connected with the travelling gear, the travelling gear with
The driving rack engagement.
Wherein in one embodiment, the display is LED display lamps.
Wherein in one embodiment, built-in power is provided with the framework, the built-in power is aobvious with the sensing
Show that module is electrically connected.
In sum, using above-mentioned technical proposal, height gauge is placed on survey mass on testee in measurement process,
When pawl of ruling runs into testee, due to ruling, pawl lower surface is equiped with inductor, can deliver a signal to survey mass, survey mass
Then show and contact testee to sensing display module, the display for sensing display module signal transmission, now can be with
Reading, can so avoid ruling pawl not in contact with testee or compress the error that measurement brings when testee is measured, because
This can improve the precision of measurement using this technical scheme.
Description of the drawings
Fig. 1 is a kind of structural representation of digital display height gauge of an embodiment.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is described in further detail to the utility model.
As shown in figure 1, a kind of high-precision digital-display height gauge, including height gauge body, the height gauge body includes base
1st, tooth bar 2, driving rack 3, framework 4, handwheel 5, line pawl 6 and locking system 7, the counting tooth bar 2 and driving rack 3 are counted
Parallel, on the base 1, the framework 4 is sheathed on the counting tooth to tooth bar 2 and the mounted perpendicular of driving rack 3 of counting
On bar 2 and driving rack 3, the handwheel 5 is installed on the framework 4, and the line pawl 6 is fixed at the framework 4 one
Side, the locking system 7 is installed in the top of the framework 4, and the height gauge body also includes the smooth sensing in a lower surface
Block 8, the framework 4 is internally provided with sensing display module 9, and the sensor block 8 is electrically connected with the sensing display module 9, institute
Stating sensing display module 9 includes processor and display, and the lower surface of line pawl 6 is equiped with inductor 61, the inductor
61 are connected with the signal of the sensor block 8.When using, after height gauge zero, sensor block 8 is placed on testee 11, pawl 6 of ruling
Decline, when touching testee 11, the inductor 61 of the lower surface of pawl 6 installing of ruling can transmit signals to sensor block 8, sensor block
Signal transmission shows to sensing display module 9, the display sensed in display module 9 by 8 again, now can be with survey measurements, can
Visually observe whether line pawl 6 contacts testee 11 to save, detection can also be improved while certainty of measurement is ensured and is surveyed
