Description
Technical field
The present invention relates to the fine balance bearing calibration of a kind of super-abrasive grinding wheel.
Background technology
Emery wheel is the critical component of grinding, but owing to organizing in its foozle, use alignment error and emery wheel
The reason such as uneven, often causes wheel unbalance, and then causes grinding process system vibration, reduces Grinding Machining Quality,
Even there is safety in production hidden danger.
Wheel balance mainly divides gravity type balance and centrifugal balance.Gravity type balance also referred to as static balance, is usually sleeping
On formula balancing stand, imbalance is measured in the action of gravity relying on emery wheel self, and grinding wheel static balancing uses face the widest, but balance quality
Low.Centrifugal balance is also referred to as dynamic balancing, is under rotation status, and the vibration force that foundation wheel unbalance causes is to measure injustice
Weighing apparatus, dynamic balancing defiber dynamic balancing and on-line dynamic balancing again, off-line dynamic balancing is by artificial duplicate removal (or weightening finish) on emery wheel
Adjusting the balance that emery wheel is new, wheel balance precision is high, but labor intensity is big, efficiency is low；On-line dynamic balancing is at numerically control grinder
On wheel unbalance situation carried out on-line checking and from dynamic(al) correction, balance efficiency is high, precision is high, is mainly used in high-grade numerical control grinding
Bed, but on-line automatic dynamic balancing detection range is limited, requires higher to the initial unbalance of emery wheel, even goes back before machine on emery wheel
Need to carry out static balance or off-line dynamic balancing detection, correction.
In super-abrasive grinding wheel manufacture process, emery wheel dispatch from the factory before balance correction mainly use off-line dynamic balancing detection and
Technique in grinding wheel base body one side key area duplicate removal.I.e. by drilling, milling remove grinding wheel base body one side barycentric area suitable
Quality, makes emery wheel reach new balance quality requirement.But this kind of method needs repeated detection grinding wheel unbalance value, repeatedly drilling or milling
Cutting adjustment, removal amount is difficult to control to, and duplicate removal point quantity differs, is distributed relatively disorderly, and duplicate removal hole depth affects emery wheel outward appearance matter
Amount；Further, going to vary in weight because of each emery wheel, it is difficult to quantify to produce, anthropic factor impact is big, and work efficiency is relatively low.
During emery wheel uses, on general-purpose grinder, the balance correction of emery wheel mainly uses one side to put down on grinding wheel flange
Weighing apparatus block ballasting method, but in use this bearing calibration has following defects that one carrys out balance weight and axially deposits with emery wheel center of gravity
In distance, it is easily generated new couple, affects emery wheel whole machine balancing precision；Two carry out balance weight mostly is a little with the grinding wheel flange way of contact
, there is balance weight tendency toward sliding in contact or linear contact lay；The three dovetail annular grooves carrying out grinding wheel flange are all reserved with balance weight access way,
Reduce the most again wheel balance precision.
Summary of the invention
It is an object of the invention to provide the fine balance bearing calibration of a kind of super-abrasive grinding wheel, it is intended to improve wheel balance
Precision, make wheel balance correction quick, accurately, batch for super-hard abrasive tool manufacture and use.
In order to realize object above, in the present invention, the technical scheme of the fine balance bearing calibration of super-abrasive grinding wheel is such as
Under: the fine balance bearing calibration of super-abrasive grinding wheel, comprise the following steps:
Step one, offers 3-6 uniform balance pipe on the same circumference of the base end of emery wheel, and gives peace on each balance pipe
Dress is for blocking the plug in the aperture of balance pipe, to be formed emery wheel to be corrected by emery wheel and plug；
Step 2, tests the amount of unbalance of emery wheel on dynamic balancing machine, uneven with the original center of gravity position and emery wheel determining emery wheel
Weighing apparatus square M；
Step 3, crosses original center of gravity on abrasive wheel end face and X-axis is set up in the center of circle, and emery wheel dubs with original center of gravity about in X-axis
Heart O is symmetrical, emery wheel dubs the X-axis line both sides in region and is defined as emery wheel correction apart from 2 balance pipes that X-axis line is nearest
First, second counterweight hole；
Step 4, is respectively mounted mass in first, second counterweight hole, and with plug, mass closure is fixed on counterweight hole
In, two mass need to meet following condition: m0E=m1rcosθ+m2Rcos (360/n-θ)=M, m1Rsin θ=m2rsin(360/
N-θ), in formula: m0For emery wheel quality, e is the absolute value of original center of gravity coordinate in X-axis, and r is counterweight hole and emery wheel body
Centre-to-centre spacing, m1And m2Being the quality of mass in first, second counterweight hole, θ is the phase angle relative to X-axis, the first counterweight hole, n
Quantity for balance pipe.
Each balance pipe is tapped blind hole, and each plug is plug, and mass is fixedly clamped at the inner of plug and screw thread
Between the blind end of blind hole.
Mass is the weights coordinated with tapped blind hole concentric gap or counterweight powder or counterweight colloid.
In step 4, the weight of mass weighs with scale.
In in the present invention, mass is integrally fixed at the counterweight hole of emery wheel, this increases emery wheel indeed through mass
On dub the quality in region, so that the center of gravity of whole emery wheel falls back to shaft core position；Simultaneously as mass can be by precision
Balance segments, thus improves wheel balance precision；Further, since grinding wheel base body counterweight hole is the premise at test amount of unbalance
Front prefabricated, uniform layout, wheel balance so can be made to correct fast, accurately, in batches, then can be used for super-hard abrasive tool batch raw
Produce, improve emery wheel presentation quality.
