Description
Technical field
The invention belongs to piece test technical fields, are specifically related to a kind of three-jaw centering formula axial workpiece detection device.
Background technology
It is carried out on workbench currently, the measurement of axis or cover parts is generally taken or is placed on using hand, it is common to grasp
Have as method following several：
(1) using workpiece is taken on the other hand, when taking measurer on the other hand to workpiece progress corresponding size measurement, due to having oil on workpiece,
Workpiece easily slides, and can injure workpiece by a crashing object or injure people by a crashing object, while can increase each dimensional measurement error；
(2) it using the method measured on platform is placed on, has shaking or places shakiness, result in measuring inaccurate
Really, or even injure workpiece and measurer by a crashing object；
(3) for axis or cover parts geometric tolerances measurement, general cooperation uses contour V-type seat, but workpiece
Rotate dumb, this method is time-consuming, arduously, extremely inconvenient, and measurement error is caused to increase；
(4) it if measured using highly sophisticated devices such as three coordinates, should not use at the scene, cost and too high, cost performance
It is low.
To overcome the shortcomings of the axial workpiece detection for occurring various samples present in existing axial workpiece measurement method at present
Device.For example, the Chinese patent of Publication No. CN203203556U discloses a kind of axial workpiece detection device, instrument is to calculate
Machine is hardware platform with data acquisition equipment, coordinates necessary sensor, signal condition equipment and data collecting card composition a set of
Axial workpiece comprehensive detector can carry out the multiple parameters detection of axial workpiece, such as length, diameter, circularity, cylindricity, coaxial
Degree, circle bounce, taper etc., this test system has detection efficiency high, and precision is high, easy to use, friendly interface, measurement parameter
More, cost-effective features is suitble to all kinds of detection workshops to use.But the device is that part is clamped using top, because
The clamping of this part is inconvenient, and rotation is dumb, while top easily causing to damage to part.
For another example, the Chinese patent of Publication No. CN201145560Y discloses a kind of macrotype axes series parts detection device, packet
Two sets of holders are included, horizontal alternate equipped at least two semicircle orifices on the holder, institute can be placed in by further including at least four
The locating shaft in semicircle orifice stated is cased with bearing on the locating shaft.Although the device replaces V-type using ball bearing outer circle
Iron inclined-plane largely reduces axis to bevel friction power.But the device is cannot to form firm folder using 2 points of supports
It holds, is that part easy tos produce shaking, and easily causes part landing when rotational parts in measurement, to increase measurement error, reduces
The measurement accuracy of part.
