Description
Technical field
The present invention relates to lathe belt pulley mandrel tool technical field, specifically high precision machine tool belt pulley dynamic balancing
Dedicated mandrel tool.
Background technique
With the continuous improvement of China's scientific and technological level, the required precision for being machined auxiliary equipment is also higher and higher, thus right
More stringent requirements are proposed for its accuracy and speed for processing machine tool numerical control machine tool.As numerical control machine tool power transmission part
The belt pulley of part, due to motor high speed rotation, if bad to its dynamic balance treatment.So, in numerically-controlled machine tool high speed work
When making workpieces processing, it will cause the vibration of lathe, to directly influence the suface processing quality and machining accuracy of workpiece.Cause
This, seeks the technical solution for improving belt pulley dynamic balance accuracy, particularly significant.
Summary of the invention
The purpose of the present invention is to provide a kind of dedicated mandrel tools of high precision machine tool belt pulley dynamic balancing, mention for solving
The technical issues of high machine tool drive belt pulley dynamic balance performance.
The technical scheme adopted by the invention to solve the technical problem is that:
The dedicated mandrel tool of high precision machine tool belt pulley dynamic balancing, including mandrel ontology, spring ringfeder and locking nut；
The both ends of mandrel ontology are equipped with the outer circle terminal connecting with dynamic balancing lathe, and in-between position is equipped with and belt pulley wheel
The matched taper outer circle in hole；Spring, which rises, to be set between the taper outer circle and belt pulley wheel bore, and tensioner spring ringfeder is used for
Locking nut be mounted between mandrel ontology and the outer end of belt pulley.
Further, the taper of the taper outer circle is 1:20.
Further, the spring ringfeder outside diameter and belt pulley wheel aperture fit clearance are 0.02~0.06mm.
Further, the spring ringfeder and taper outer circle facing-up, contact area >=85%.
Further, the spring ringfeder is by 65Mn spring steel making, and thermally treated quenching treatment.
The effect provided in summary of the invention is only the effect of embodiment, rather than invents all whole effects, above-mentioned
A technical solution in technical solution have the following advantages that or the utility model has the advantages that
The position gap error in the prior art between dynamic balancing mandrel outer circle and belt pulley wheel bore is completely eliminated, it can be very big
Ground improves the dynamic balance accuracy of belt pulley, to ensure that the stability and balance of lathe.
Detailed description of the invention
Fig. 1 is the application state structure matching relationship schematic diagram of the embodiment of the present invention；
In figure: 1, mandrel ontology；11, outer circle terminal；12, taper outer circle；2, spring ringfeder；3, locking nut；4, belt
Wheel.
Specific embodiment
In order to clearly illustrate the technical characterstic of this programme, below by specific embodiment, and its attached drawing is combined, to this
Invention is described in detail.It should be noted that illustrated component is not drawn necessarily to scale in the accompanying drawings.Present invention omits right
Known assemblies and technical description are to avoid being unnecessarily limiting the present invention.
As shown in Figure 1, the dedicated mandrel tool of high precision machine tool belt pulley dynamic balancing, including mandrel ontology 1, spring ringfeder 2
With locking nut 3.
The both ends of the mandrel ontology 1 are the outer circle terminal 11 of size Φ 30h6, for connecting dynamic balancing lathe.Mandrel sheet
The intermediate position of body 1 is the taper outer circle 12 of taper 1:20, and taper outer circle 12 is for matching connection belt pulley 4.Outside the taper
The spring ringfeder 2 is installed, spring ringfeder 2 is by 65Mn spring steel making and through heat between circle 12 and the wheel bore of belt pulley 4
Reason quenching treatment.2 outside diameter of spring ringfeder and belt pulley 4 take turns apertures, and gap is 0.02~0.06mm；Spring ringfeder 2
1:20 taper hole and mandrel ontology 1 12 facing-up of taper outer circle, it is desirable that its contact area >=85%.
Spring ringfeder 2 is put into 4 aperture of belt pulley when use, then is put into togerther at the taper outer circle 12 of mandrel ontology 1,
Make 2 tensioner belt pulley 4 of spring ringfeder by tightening locking nut 3, is fixed on workpiece on dynamic balancing tooling to reach.It sets in this way
The position gap error between dynamic balancing mandrel outer circle and belt pulley wheel bore in the prior art is completely eliminated in meter, can greatly mention
The dynamic balance accuracy of high belt pulley, to ensure that the stability and balance of lathe.
Except for the technical features described in the specification, it all is technically known to those skilled in the art.
Above-mentioned, although the foregoing specific embodiments of the present invention is described with reference to the accompanying drawings, not protects model to the present invention
The limitation enclosed, based on the technical solution of the present invention, those skilled in the art, which do not need to pay for creative labor, to be done
Various modifications or changes out are still within the scope of the present invention.
