Description
Technical field
The present invention relates to a kind of survey tool, more particularly to a kind of machine tool chief axis and the instrument of guide sleeve coaxality measurement.
Background technology
Drill gun special plane, it is a kind of special purpose machine tool that deep hole machining of the draw ratio more than 15 is carried out using elongate resilient drill gun.
The axiality of guide sleeve and main shaft is the crucial precision index of such lathe, if axiality is overproof, the hole linearity that drills out
It is unqualified, it can also cause drill gun radial load uneven, cause tipping or turn around.
The conventional method for measuring axiality is the reference for installation rod on main shaft, represents main-shaft axis.With magnetic stand
Dial gauge is fixed on bar gage, a certain position inside indicator contact guide sleeve.Live spindle, dial gauge rotation is driven, is read
Indicator offset on the section.And for drill gun special plane, due to there is receipts fuel tank among main shaft and guide sleeve, auxiliary branch above
Support bore dia is less than 60mm, has the three segment table bars by universal knot connection between conventional dial gauge and magnetic stand, is measuring
When table bar radius of turn it is excessive, cause with receiving fuel tank interference, indicator can not contact guide sleeve, it is impossible to realize measurement.
The content of the invention
It is an object of the invention to provide a kind of for drill gun special plane main shaft and the instrument of guide sleeve coaxality measurement.
Technical scheme is as follows：
A kind of coaxiality measuring tool, including the general handle of a knifes of HSK, bar gage, straight line table bar and the part of dial gauge four, the HSK
General handle of a knife is the cutter resource that drill gun special plane carries, and clamp precision is high, reliable and stable.The bar gage is that office is passed through in outer surface
The cylindrical rod of portion's grinding processing, one end clamp for handle of a knife, and the other end has internal thread hole, for fixing straight line table bar.It is described
Straight line table bar can enter the intermediate supports hole received and set on fuel tank, and through guide sleeve, clamping dial gauge is to guide sleeve inner surface
Different cross section measures.
The bar gage uses alloy tool steel material, and its a diameter of 15 arrives 30mm, and length is 200mm to 500mm；It is described
Straight line table bar and bar gage are attached by internal thread, a diameter of M5 to M15 of screwed hole, and pitch is 1mm to 2mm, screw thread
Hole depth arrives 30mm for 10.Straight line table bar material is 40Cr steel.Because straight line table bar uses 40Cr steel, the bending strength of the material
It is relatively good, so as to ensure that the rigidity of straight line table bar and dial gauge carry out the degree of accuracy of coaxality measurement.
The straight line table bar is a multi-diameter shaft, and 20mm is arrived in thinner one end a diameter of 10, and length arrives 200mm for 100, more slightly
30mm is arrived in one end a diameter of 20, and length arrives 100mm for 40.Have on the less one end face of cylinder of its diameter and spiral shell in bar gage
The aperture of pit and the consistent external screw thread of pitch, can be engaged with bar gage internal thread hole, and one end tool is relatively large in diameter at it
There is a groove from end face inward, with certain depth, the groove arrives 10mm, depth and multi-diameter shaft in diameter of axle larger part width for 6
The length of thicker one end is identical, arrives 6mm in diameter of axle smaller part width for 4, depth arrives 60mm, the width of the groove of diameter of axle larger part for 20
Degree is slightly less than the thickness of general dial gauge, is measured with guaranteeing effectively to clamp dial gauge, dial gauge is not fallen
Fall.
The dial gauge is the dial gauge of universal models, and its is cheap, and meets that the precision of lathe coaxality measurement will
Ask.
The beneficial effects of the invention are as follows：The typically dial gauge with magnetic stand can effectively be solved because table bar is with receiving fuel tank
Interference, so as to the problem of can not measuring drill gun special plane main shaft and guide sleeve axiality, because the general handle of a knifes of HSK are that lathe carries money
Source, clamp precision is high, and precision is reliable, and handle of a knife is arranged on machine tool chief axis, and its center axis is basically identical, by being pressed from both sides with handle of a knife
The cylindrical rod held and the straight line table bar connected with cylindrical rod by internal thread, the centre that easily can be set by receiving on fuel tank
Supported hole, dial gauge are clamped on straight line table bar, guide sleeve surface can be measured, before and after the slide unit where main shaft
It is mobile, can easily realize the measurement to guide sleeve different cross section, so as to avoid the general dial gauge with magnetic stand by
In interference lead to not measurement the problem of.
