Description
Technical field
The present invention relates to a kind of friction-driven trimming device of hard grinding wheel and friction-driven dressing methods.
Background technique
Hard grinding wheel refers to the grinding wheel that joined super hard abrasive by bonding agent in the grinding layer of grinding wheel, super hard abrasive packet
Include diamond and cubic boron nitride；Hard grinding wheel has excellent grinding performance, is the main research of current grinding industry
One of direction.
Many hard grinding wheels complete rear surface size be not be using when desired size (such as require the cylinder of positive round
Shape hard grinding wheel may not be positive round when just producing, and have bulge-structure or at ellipticity etc.), and super hard abrasive is general
It is all wrapped in inside bonding agent, is modified so hard grinding wheel is generally required before use, the finishing of hard grinding wheel includes whole
Two processes of shape and dressing, shaping is to carry out micro cutting or grinding to hard grinding wheel, several required by reaching hard grinding wheel
What shape and dimensional accuracy, and keep abrasive material tip micro- broken, form sharp sharpening；Dressing is the bonding agent removed between abrasive material, is made
There is certain chip space between abrasive material, and makes to form cutting edge except the prominent bonding agent of sharpening.The dressing method of hard grinding wheel is not
The dimensional accuracy of hard grinding wheel and the sharp keen degree of sharpening are only affected, wear resistance, the grinding of hard grinding wheel are had an effect on
Power, grinding temperature and surface roughness of grinding workpiece etc..
Much diamond pen is used to be modified when carrying out hard grinding wheel finishing at present, but diamond pen traverse feed is repaired
When whole hard grinding wheel, the bus of hard grinding wheel is because abrasion will become oblique line or convexity, while when diamond pen finishing hard grinding wheel
The form and dimensional precision for the hard grinding wheel that abrasion is very fast, is trimmed is poor；There are also Buddha's warrior attendants for common hard grinding wheel dressing method
The finishing of stone idler wheel, but diamond roller is very big to the pressure for the hard grinding wheel being trimmed, if lathe rigidity is insufficient, be easy to cause super
Hard grinding wheel is accomplished ellipse, and surface quality is poor, diamond roller when modifying hard grinding wheel, can only carry out shaping without
It is suitble to dressing.Both methods is all the rigid dressing method for belonging to hard grinding wheel, based on the shortcoming of rigid dressing method, people
Have investigated the elastic dressing method of hard grinding wheel.
A kind of diamond is disclosed in the Chinese patent that the notification number that on January 3rd, 2001 is announced is CN1060110C
The soft-elastic dressing method of grinding wheel, as shown in Figure 1, the corollary apparatus of the soft-elastic dressing method of the skive includes tape feed roller
101, belt wheel 102 and contact wheel 103 are put, tape feed roller 101 connects retarder (being not drawn into figure), and retarder is supplied to tape feed roller
101 power, abrasive band 104, which is wound on, puts on belt wheel 102, by contact wheel 103 then around on tape feed roller 101；Skive 105
Above contact wheel 103, abrasive band 104 is across skive 105 and contact wheel 103,103 upward pushing tow abrasive band of contact wheel
104, and abrasive band 104 is pressed on skive 105, skive 105 connects the main shaft (being not drawn into figure) of grinding machine；It should

There is opposite sliding between 105 and abrasive band 104, and then generate force of sliding friction, abrasive band 104 can be to Buddha's warrior attendant by force of sliding friction
Stone sand wheel 105 is modified.
Although the soft-elastic dressing method of above-mentioned skive avoids damage of the rigidity finishing to hard grinding wheel, but also
Following problem: 1) above-mentioned elastic dressing method is to oppress abrasive band by contact wheel to contact with the grinding wheel being trimmed, and abrasive band exists
The advantage that elasticity is not embodied on contact wheel, can not be deep into bonding agent layer, dressing process remains the abrasive material above abrasive band
It is mutually collided with the abrasive material for the grinding wheel being trimmed, to achieve the effect that finishing, this is with traditional rigidity finishing without significant difference；2)
In above-mentioned elastic dressing method, grinding wheel rotates at a relatively high speed when finishing, and tape feed roller then slowly rotates, and abrasive band is driven slowly to move,
According to industry wisdom, under equal conditions, slow abrasive band is in by the state of wheel grinding, does not have the effect of finishing,
And the abrasive material of hard grinding wheel is two kinds of most hard materials, can not be modified with common abrasive band, that is, uses super-abrasive grinding band, because
Sand-bed test is relatively also unable to reach the effect of finishing slowly；3) as described in text " after the skive surface abrasive after dressing
Face is not bound with agent comet tail, and abrasive material projecting height is moderate ", this belongs to the synonymous substitution of conventional rigid finishing, rigidly modifies
Shaping effect accounting is big, does not almost have the effect of dressing；4) abrasive band poor continuity is needed when putting the abrasive band on belt wheel and discharging
It replaces and puts belt wheel, reduce dressing efficiency；5) as the abrasive band circle number being wrapped on tape feed roller increases, it is wrapped in reducer shaft
On abrasive band overall thickness increase, since retarder revolving speed is fixed, so the speed of travel in abrasive band is gradually increased, will affect in this way
The finishing of skive；6) contact wheel compressing abrasive band is contacted with the grinding wheel being trimmed, and the contact site of abrasive band and grinding wheel is only
Seldom a part, elastic effect are poor；7) when using above-mentioned apparatus finishing grinding wheel, usually operator is seen using magnifying glass
Wheel face situation is examined to judge whether grinding wheel modifies completion, operation is more troublesome and artificial sense organ error is big.
