Description

A kind of cubing for detection of planeness of workpiece
Technical field
The present invention relates to planeness of workpiece detection technique field, relate in particular to a kind of cubing for detection of planeness of workpiece.
Background technology
In mechanical processing industry, the piece surface after machine work or die casting, the blank surface of casting, its flatness has technical requirement, must after measuring, judge that whether it is qualified.
Current better simply detection method is: choosing workpiece plane opposite face to be measured is reference field, measures plane to be measured many places height with the precision measurement such as vernier caliper, milscale instrument, and the time that detection workpiece needs is longer.For the detection of workpiece slope that there is no relative datum face, must choose on workpiece multiple reference fields and treat lining face and detect, not only detecting step is comparatively loaded down with trivial details, and also out of true of result.
And existing flatness checking device is detecting when workpiece, performance is single, cannot regulate, and detects the time that workpiece needs longer simultaneously, and very high to the requirement on machining accuracy of workpiece, cannot carry out mass detection.And a lot of adjustable pick-up units often occur that equipment volume is too huge, mobile inconvenient problem.But cannot meet for producing required quick, a large amount of testing requirement.
Summary of the invention
In order to solve the technical matters existing in background technology, the present invention proposes a kind of cubing for detection of planeness of workpiece, detect the flatness of plane to be measured by the difference of dial gauge, not only easy to detect quick, and detection sensitivity is high, testing result is more accurate.
A kind of cubing for detection of planeness of workpiece that the present invention proposes, for the processing plane degree of workpiece for measurement is detected, comprise L-type base and at least two measuring instruments, wherein, L-type base has the first reference field and the second reference field, the first reference field is horizontally disposed, the load plane of workpiece for measurement and plane to be measured can be adjacent to respectively the first reference field and the second reference field, at least two measuring instruments are installed in parallel on the second reference field and are positioned in same level, the detection head of measuring instrument stretches out and is located along the same line from the second reference field, the detection head of measuring instrument is for conflicting with the plane to be measured of workpiece for measurement.Along reference field translation workpiece for measurement, by observing the variation of measuring instrument numerical value, judge the processing plane degree of plane to be measured.
Preferably, described cubing comprises three measuring instruments.
Preferably, described measuring instrument is dial gauge or clock gauge or ten thousandth micrometer.Dial gauge, clock gauge, ten thousandth micrometer are all principles of utilizing rack pinion or lever-gear transmission, the straight-line displacement of sounding rod are become to the measurement instrument of the angular displacement of pointer; The measuring head of instrument contacts with plane to be measured, and the small rectilinear movement of sounding rod that plane out-of-flatness to be measured causes is amplified through gear drive, becomes the rotation of pointer on index dial, thereby judges the processing plane degree of plane to be measured.
Preferably, the angle between described the first reference field and described the second reference field is 90 °.
Preferably, the plane to be measured of described workpiece for measurement is inclined-plane or vertical plane.
The present invention is for detection of the cubing of planeness of workpiece, utilize the sensitivity of measuring instrument to detect the flatness of plane to be measured, in order to improve accuracy and the practicality of detection, adopt plural measuring instrument, by observing the variation of measuring instrument numerical value, more accurately judge the processing plane degree of plane to be measured.Compared with the flatness that detects workpiece with the simple and easy cubing of employing, the present invention is not only easy to detect quick, and detection sensitivity is high, and testing result is more accurate.
Brief description of the drawings
Fig. 1 is the structural representation of a kind of cubing for detection of planeness of workpiece of proposing of the present invention.
Embodiment
As shown in Figure 1, Fig. 1 is the structural representation of a kind of cubing for detection of planeness of workpiece of proposing of the present invention.
With reference to Fig. 1, a kind of cubing for detection of planeness of workpiece that the present invention proposes, for the processing plane degree of workpiece for measurement 4 is detected, described cubing comprises L-type base 1 and three measuring instruments, in the present invention, measuring instrument is dial gauge 5, wherein, L-type base 1 has the first reference field 3 and the second reference field 2, the first reference field is horizontally disposed, between the second reference field, longitudinally arrange, angle is between the two 90 °, the load plane of workpiece for measurement and plane to be measured can be adjacent to respectively the first reference field 3 and the second reference field 2, three dial gauges 5 are installed in parallel on the second reference field 2 and are positioned in same level, the detection head 6 of dial gauge 5 stretches out and is located along the same line from the second reference field 2, the detection head 6 of dial gauge 5 is for conflicting with the plane to be measured 7 of workpiece for measurement.Along reference field translation workpiece for measurement 4, by observing the variation of dial gauge 5 numerical value, judge the processing plane degree of plane to be measured.
In Fig. 1, the plane to be measured 7 of workpiece for measurement 4 is positioned at the inclined-plane of same plane for interval arranges, the measuring head 6 of dial gauge 5 is inconsistent with plane 7 to be measured, now the numerical value of dial gauge 5 is consistent, along reference field translation workpiece for measurement 4, the small rectilinear movement of dial gauge 5 sounding rods that the out-of-flatness meeting of plane 7 to be measured causes, becomes the rotation of pointer on index dial, thereby accurately judges the processing plane degree of plane to be measured.
The present invention is for detection of the cubing of planeness of workpiece, utilize the sensitivity of dial gauge to detect the flatness of plane to be measured, in order to improve accuracy and the practicality of detection, adopt plural dial gauge, by observing the variation of dial gauge numerical value, more accurately judge the processing plane degree of plane to be measured.Compared with the flatness that detects workpiece with the simple and easy cubing of employing, the present invention is not only easy to detect quick, and detection sensitivity is high, and testing result is more accurate.
The above; it is only preferably embodiment of the present invention; but protection scope of the present invention is not limited to this; any be familiar with those skilled in the art the present invention disclose technical scope in; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
