Embodiment

Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.

With reference to shown in Figure 1, the device of the vertical calibration of three-dimensional tester that is applicable to of the present invention comprises: be used to make it to be fixed onvertical support bar 1 on the three-dimensional tester test platform, be arranged on dismountable engaged test appearance of supporting bar top;Support bar 1 bottom is formed withexternal thread section 2, and the engaged test appearance comprises:main body 3, be arranged on body interior touch switch circuit, be arranged on main bodytop measurement instrument 7, can change thecontact sonde 4 that shows numerical value to the touch switch circuit feedback signal and at measurement instrument through self-position; Butcontact sonde 4 constitutes being rotationally connected of elastic recovery with main body 3.Measurement instrument 7 can reflect the off-set value of probe, also is provided with the pilot lamp 8 that is used to show detection case as preferredmain body 3.

As preferred version,contact sonde 4 be provided withmain body 3 away fromsupport bar 1 one ends and outwards level stretch out, to stretch out the length direction that is meant contact sonde be level when not receiving external force to level here.Form step betweenexternal thread section 2 and supportbar 1 other parts, the benefit of this step is to makesupport bar 1 conveniently to be placed in the pilot hole of test board of three-coordinates measuring machine.

As preferred version,support bar 1 can separate withmain body 3, andsupport bar 1 top is provided with the lateral aperture that is used for the plug-in mounting aforementioned body.As preferably, in order can better to fix, also be provided with thecheck lock lever 5 that is used to lock main body at the sidewall ofsupport bar 1.

When calibration,, moved up and down by thecontactant 6 that the topworks of three-dimensional tester drives at vertical direction,contact sonde 4 contacts with it, when the vertical direction deviation, the position change ofcontact sonde 4, thus realize calibration.

The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
