Description
Technical field
The utility model is related to a kind of survey tool more particularly to a kind of machine tool chief axis and the works of guide sleeve coaxality measurement
Tool.
Background technology
Drill gun special plane 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 concentricity of guide sleeve and main shaft is the crucial precision index of such lathe, if concentricity is overproof, the hole straightness that drills out
It is unqualified, it can also cause drill gun radial load uneven, lead to tipping or turn around.
The conventional method for measuring concentricity is the reference for installation stick 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 drives dial gauge rotation, reads
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
It supports bore dia and is less than 60mm, have the three segment table bars by universal knot connection between conventional dial gauge and magnetic stand, measuring
When table bar radius of turn it is excessive, cause with receiving fuel tank interference, indicator cannot contact guide sleeve, it is impossible to realize and measure.
Invention content
The purpose of this utility model is to provide a kind of for drill gun special plane main shaft and the tool of guide sleeve coaxality measurement.
The technical solution of the utility model is as follows：
A kind of coaxiality measuring tool, it is described including the general handle of a knifes of HSK, four part of bar gage, straight line table bar and dial gauge
The general handle of a knifes of HSK are the cutter resources that drill gun special plane carries, and clamp precision is high, reliable and stable.The bar gage is passed through for outer surface
The cylindrical rod of partly processing is crossed, one end clamps for handle of a knife, and the other end has internal thread hole, for fixing straight line table bar.
The straight line table bar can enter the intermediate supports hole received and set on fuel tank, and across guide sleeve, clamping dial gauge is in guide sleeve
Surface different cross section measures.
The bar gage a diameter of 15 arrives 30mm, and length is 200mm to 500mm；The straight line table bar and bar gage pass through
Internal thread is attached, a diameter of M5 to M15 of threaded hole, and screw pitch is 1mm to 2mm, and screw thread hole depth is 10 to 30mm.
The straight line table bar is a multi-diameter shaft, and 20mm is arrived in thinner one end a diameter of 10, and length is 100 to 200mm, more slightly
30mm is arrived in one end a diameter of 20, and length is 40 to 100mm.Have on the smaller one end cylindrical surface of its diameter and spiral shell in bar gage
The aperture of pit and the consistent external screw thread of screw pitch, can match with bar gage internal thread hole, and one end tool is relatively large in diameter at it
There is a slot from end face inward, with certain depth, which is 6 to 10mm, depth and multi-diameter shaft in diameter of axle larger part width
The length of thicker one end is identical, is 4 to 6mm in diameter of axle smaller part width, depth is 20 to 60mm, the width of the slot of diameter of axle larger part
Degree is slightly less than the thickness of general dial gauge, is measured with guaranteeing effectively to clamp dial gauge, will not fall dial gauge
It falls.
The dial gauge is the dial gauge of universal models, cheap, and the precision for meeting lathe coaxality measurement will
It asks.
The beneficial effects of the utility model are：The generally dial gauge with magnetic stand can effectively be solved since table bar is with receiving
Fuel tank interfere, so as to can not measure drill gun special plane main shaft and guide sleeve concentricity the problem of, due to the general handle of a knifes of HSK for lathe from
Band resource, clamp precision is high, and precision is reliable, and handle of a knife is mounted on machine tool chief axis, and center axis is basically identical, by with knife
The cylindrical rod that spindle clamp is held and the straight line table bar connected with cylindrical rod by internal thread, can be easily by receiving what is set on fuel tank
Intermediate supports hole, dial gauge are clamped on straight line table bar, and guide sleeve surface can be measured, pass through the slide unit where main shaft
It is moved forward and backward, the measurement to guide sleeve different cross section can be easily realized, so as to avoid the general percentage with magnetic stand
The problem of table leads to not measure due to interference.
