Abstract
The present invention is double-sided contact clamping method of tool system, belongs to the connection method between tool system and main shaft of machine tool, and possesses the advantages of high connecting rigidity, high precision, reliable clamping and moderate tool system making cost. The double-sided contact clamping method of tool system includes the following steps: 1. machining the taper shank of tool system in the design requirement and measuring the practical sizes of the machined taper shank; and 2. making compensation ring with thickness determined based on the machining error of the taper shank and inner diameter fitting the taper shank, and setting the compensation ring between the taper shank and the clamping surface of the main shaft before clamping.
Description
Technical field:
The present invention is relevant with the method for attachment of tool system and machine tool chief axis.
Background technology:
In order to adapt to the demand of high-speed overload machining, tool system and machine tool chief axis ways of connecting by single face contact gripping/constraint principles to double-sided contact tight/the constraint principles development, big 7: 24 the BIG-PLUS tool system clear and company's exploitation of 1: 10 hollow short taper shank HSK tool system, Japan carried out of international standard all meets the tight operation principle of double-sided contact in recent years; Under the effect of machine tool chief axis clamping force, the taper hole inner conical surface and the end face of machine tool chief axis contact with end face simultaneously with the male cone (strobilus masculinus) of tool system shank respectively.The realization double-sided contact is tight, requirement has very high physical dimension and form accuracy, also exigent simultaneously positional precision, that is: the conical surface clamps the positional precision between contact point and the end face, therefore, be used for comparing of the tight machine tool chief axis of double-sided contact and tool system and traditional single face contact gripping, design strengthens with manufacture difficulty, and manufacturing cost increases.In fact from making angle, it only is the inside and outside conical surface of machining high-precision, the linearity that guarantees high-precision tapering tolerance and bus is difficult, and will guarantee simultaneously that also high-precision position dimension tolerance is just difficult more between conical surface clamping contact point and end face.Because above-mentioned foozle is often bigger, therefore when machine tool chief axis clamps, between two conical surfaces and between two end faces simultaneously the state (restrained condition) of contact gripping change greatlyyer, be difficult to guarantee to reach between tool system and the machine tool chief axis connection rigidity of expection and the reliability of clamping.
The content of invention:
The purpose of this invention is to provide a kind of double-sided contact clamping method of tool system, under the situation that reduces manufacture difficulty and manufacturing cost, can guarantee the reliability of rigidity, precision and clamping that tool system is connected with machine tool chief axis.
The present invention is achieved in that
Double-sided contact clamping method of tool system of the present invention comprises the steps:
(1) according to the male cone (strobilus masculinus) and the main shaft inner conical surface datum diameter d of designing requirement machining tool system taper shank
2Locate to clamp the distance of end face and clamp the distance of end face to main shaft to taper shank, after machining, actual measurement two conical surface datum diameter places clamp the distance L of end face to taper shank
I is real, clamp the distance L of end face to main shaft
Axle is real, both actual size difference h
Real=L
I is real-L
Axle is real,
(2) make compensated loop, its thickness h=h
Real, its internal diameter cooperates with the cylinder of taper shank, is placed between the clamping end face of taper shank and main shaft the back and implements the clamping measure.
Structure and principle that actual measurement in the step (2) is recommended with reference to the mechanical industry standard of China " HSK instrument taper gage ".
Said tool system is 7: 24 tool systems or HSK tool system, said datum diameter d
2, for the hollow cone interface that has flange contact facings is the HSK tool system, be exactly the d that stipulates among standard GB/T 19449.1-2004/ISO 12164-1:2001 and standard GB/T19449.2-2004/ISO 12164-2:2001
2, datum diameter d
2For 7: 24 tool systems was exactly the D that stipulates among standard GB/T 11854-2003
2, adopt universal tool microscope or coordinate measuring machine or HSK instrument taper gage to measure d
2And d
2With the distance that clamps end face.
Said tool system is the taper shank cutter of flanged (FLGD) 7: 24 tool systems or HSK.
The thickness h of compensated loop is 2-20mm.
Advantage of the present invention is:
1, machine tool chief axis and tool system according to the tight principle work of double-sided contact, under the prerequisite of guaranteeing to have the coupling stiffness, precision and the clamping reliability that are equal to, owing to adopted shim, in tapered bore of machine tool spindle and the design of tool system taper shank and making, reduce the required precision of axial location between the conical surface and the end face, reduced manufacture difficulty.
2, the conical surface of the tapered bore of machine tool spindle that obtains according to actual measurement and the axial location size between the end face, and the conical surface of the tool system taper shank that obtains of actual measurement and the axial location size of end face, optimize the thickness of selection and definite compensated loop, can satisfy the tight requirement of double-sided contact by high-quality, improve clamping rigidity and reliability.
3, for original single face contact gripping tool system and machine tool chief axis, add compensated loop corresponding, the suitable thickness size, just can realize that double-sided contact is tight, improve the rigidity of clamping system.
