Abstract

The invention discloses precision measurement of a tapered bore of a machine tool spindle, belongs to the taper measurement field, in particular to the precision measurement of a tapered bore of a machine tool spindle, comprising the following steps: measuring bore size, roundness and linearity of the tapered bore of a spindle on an inner-aperture grinder by a standard plug gage in a traditional method, connecting with an inner tapered bore of the spindle via a connection sleeve (3), a check bar (2) and a blind rivet (4), installing a gasket (5) and a hexagon nut (6) on the other end of the blind rivet (4), enabling the gasket (5) to close to the end surface of the machine tool spindle (1) and using the hexagon nut (6) to compress so as to enable the blind rivet to tighten the check bar (2) and the check bar (2) to be tightly matched with the tapered bore of the spindle, and measuring the runout of the tapered bore of the spindle by a micro meter measurement method. If the precision is unqualified, the inner-aperture grinder is adopted again to grind and process continuously until the precision meets the drawing requirement.

Description

The precision measure of tapered bore of machine tool spindle
Technical field
The present invention relates to a kind of precision measure of tapered bore of machine tool spindle, belong to the taper measurement field, specifically the precision measure of tapered bore of machine tool spindle.
Background technology
The measuring method of taper hole generally is to check with feeler gauge, in order to guarantee to measure the precision and the degree of accuracy of taper hole, the operator must be with tested taper hole wiped clean before measuring taper hole, must not leave any foreign matter, during measurement feeler gauge being put into the dynamics of taper hole wants suitably, firmly can not kick the beam or too quickly, otherwise all will have influence on the measurement of taper hole precision.Feeler gauge check taper hole tradition adopts colouring, and the circularity of taper ratio and taper hole and the linearity of taper hole then depend on vision and sensation subjective assessment fully, and the size in aperture, is to convert definite by the degree of depth that feeler gauge stretches into taper hole.
The accuracy relation of tapered bore of machine tool spindle is to the machining accuracy of whole lathe, and simple feeler gauge check can not be satisfied its requirement.Traditional tapered bore of machine tool spindle generally carries out half correct grinding in job shop, then after the assembly shop is assembled whole lathe by the assembly crewman, use the check rod accuracy of detection, and then finish grind, can eliminate the accumulated error in the assembling process like this, but owing to adopt this method correct grinding spindle taper hole, processing gets up not to be very convenient, for not being very accurate machine tool chief axis (main axis jerking is in 0.015mm) generally, will certainly improve production cost, extend manufacture cycle, reduce production efficiency.
Summary of the invention
The invention provides a kind of precision that can guarantee spindle taper hole, simultaneously be convenient for measuring again and process, reduce the production cycle and enhance productivity, Ben Faken adopts check rod to detect the spindle taper hole precision, can directly on grinding machine, carry out half correct grinding and correct grinding processing, and the required precision (main axis jerking is in 0.015mm) that can guarantee to assemble the back machine tool chief axis.
The technical solution adopted for the present invention to solve the technical problems is:
On the endoporus grinding machine, measure earlier pore size, circularity and the linearity of spindle taper hole, utilize this measurement device to go out the beating degree of spindle taper hole then, it is characterized in that with conventional method standard feeler gauge:
A, adapter sleeve (3) one ends are connected by the internal thread of external screw thread with check rod (2), the other end matches by the external screw thread of internal thread and blind rivet (4), blind rivet (4) other end is equipped with packing ring (5) and hex nut (6), packing ring (5) is near the end face of machine tool chief axis (1), and compress by hex nut (6), check rod (2) and spindle taper hole are closely cooperated;
B, measure the beating degree of spindle taper hole at standard test rod (2) near point A and far point B place with micron (um) table;
C, on the endoporus grinding machine, be ground to the requirement of spindle taper hole beating degree.
The precision measure step of tapered bore of machine tool spindle:
1. after the lathe car went out tapered bore of machine tool spindle, grinding taper hole on endoporus mill, and check with conventional method standard feeler gauge was till taper hole circularity and linearity and pore size meet the drawing requirement.
2. utilize following apparatus to measure the beating degree of taper hole then, and carry out grinding, till beating degree meets the drawing requirement with the endoporus mill.
This technical scheme comprises spindle taper hole check rod, adapter sleeve and positioner.
The standard test rod is filled in tapered bore of machine tool spindle, and the standard test rod has an end of tapering to be connected with adapter sleeve by internal thread.
Adapter sleeve one end is connected with the standard test rod by external screw thread, and an end is connected with positioner (blind rivet) by internal thread.Consider different tapered bore of machine tool spindle differences, the size of standard test rod is also different, thereby the internal thread specification of standard test rod is also different, so the adapter sleeve external screw thread is made different specifications according to the difference of standard test rod internal thread specification, uses one to one.
Positioner has blind rivet, packing ring and hex nut to constitute.
All there is external screw thread at the blind rivet two ends, and an end cooperates with adapter sleeve, and the other end is equipped with packing ring, and compresses by hex nut.
Packing ring is near the machine tool chief axis end face, and is fixed with hex nut.
Adopt above technical scheme, can make the standard test rod closely with the tapered bore of machine tool spindle combination, utilize micron (um) table can measure the beating degree of tapered bore of machine tool spindle accurately.
The invention has the beneficial effects as follows:
1. not only can measure circularity, linearity and the pore size of spindle taper hole, but also can measure the beating degree of spindle taper hole accurately.
2. in-process gaging does not need the part of clamp position on the lathe is taken off, and is convenient to the further processing of part.
3. directly can on grinding machine, finish whole grinding process of tapered bore of machine tool spindle, not need to carry out grinding again after the lathe assembling, raise the efficiency, save time and cost.
4. compact conformation of the present invention, easy to operate, detection efficiency is high, labour intensity is low.

Among the figure: the 1-machine tool chief axis; 2-tapered bore of machine tool spindle standard test rod; The 3-adapter sleeve; The 4-blind rivet; The 5-packing ring; The 6-hex nut.
The specific embodiment
Pore size, circularity and the linearity of spindle taper hole are measured earlier in the precision measure of tapered bore of machine tool spindle with conventional method standard feeler gauge on the endoporus grinding machine, up to the measurement that is worked into the spindle taper hole beating degree below carrying out again after meeting the drawing requirement.
Adapter sleeve 3 one ends are connected by the internal thread of external screw thread with check rod 2, the other end matches by the external screw thread of internal thread and blind rivet 4, blind rivet 4 other ends are equipped with packing ring 5 and hex nut 6, packing ring 5 is near the end face of machine tool chief axis 1, and compress by hex nut 6, thereby make blind rivet tension check rod 2, check rod 2 and spindle taper hole are closely cooperated.
Starting lathe rotates, measure at standard test rod near point A and far point B place by drawing with micron (um) table, can obtain the beating degree of tapered bore of machine tool spindle, do not meet the drawing requirement as the tapered bore of machine tool spindle beating degree, then need the endoporus grinding machine to proceed grinding, till the beating degree of tapered bore of machine tool spindle meets the requirements.
