Description
Technical field
The invention belongs to Brazilian disc technology fields, and in particular to a kind of guarantee Brazilian disc end face flatness
Processing method and its device.
Background technology
As domestic and international geotechnical engineering rapidly develops, the rupture failure process and mechanism of study of rocks class fragile material are right
It all has very important significance in relevant engineering design, construction, estimation of stability etc..The tensile strength of rock is rock
One important mechanics parameter since the tensile strength of rock is much smaller than the compression strength of rock, has many situations, rock in engineering
The destruction of body is all tensile failure.International Rock mechanics association suggests, using the drawing of Brazilian disc test specimen indirectly testing rock
Intensity is stretched, and the machining accuracy of Brazilian disk specimen has large effect for test result, when we are using different-diameter
When disk test specimen is tested, the flatness of two end faces of disk cannot be guaranteed, some processing conditions, end face irregularity degree
In more than 1mm, carry out error to test tape.Common SCM200 dual-end face grinders are to thickness（More than 50mm）Larger Brazil's circle
Disk sample is ground simultaneously from sample both ends into can ensure the flatness of disk end face substantially using two parallel emery wheels.It is but right
It is smaller in thickness（Such as less than 45mm's）Brazilian disc rock sample fixes rock since grinder needs enough spaces,
The width of its included positioning base is 45mm, lead to not simultaneously using two parallel emery wheels from sample both sides grind simultaneously into,
So another end face can only be regrinded after a honed end face.Due to disk sample treat flour milling to be in positioning base it
Outside, positioning base can only clamp circle disk sample lateral edge a part.Sample thickness is smaller, causes to press from both sides when clamping sample
A part for sample lateral edge is held, and the part for clamping sample lateral edge frequently can lead to sample unbalance stress, Brazil
The axis of disk sample cannot be perpendicular to the plane of emery wheel.In addition, the sample of clamping, unstable there is also clamping, in the mistake of mill
There are problems that sample easily moves in journey, so as to ensure that the disk end face ground is smooth.Moreover, after having ground a face,
When grinding another face, since sample thickness is relatively thin, the positioning base brought can only clamp a part for sample lateral edge, in this way
Can further result in this clamping cannot ensure with the axis of the disk twice when grinding the clamping of last end face it is parallel, so as to can not yet
Ensure the flatness of two end faces ground.Such case also frequently occurs in situation about being ground using single-sided lapping machine, due to
It needs to overturn different faces, very big error can be brought, therefore ground using SCM200 dual-end face grinders and single side there is an urgent need for a kind of
When grinding machine processes Brazilian disc, the processing method and its device of Brazilian disc end face flatness can guarantee.
Invention content
The present invention provides one kind on SCM200 dual-end face grinders and single-sided lapping machine, can be real by using a mill
Referring now to Brazilian disc two end faces in the case of separated grinding, ensure Brazilian disc end face flatness processing method and
Its device so that in 0.02mm hereinafter, when solving disc thickness less than certain size, two are held disk end face flatness error
The axis of disk two times of clamping cannot ensure parallel in process of lapping on grinder in face, can not ensure that grind two end faces are put down
Whole degree such as meets the requirements at the technical problems.
In order to solve the above technical problems, the technical solution adopted in the present invention is as follows：
A kind of processing method for ensureing Brazilian disc end face flatness, step are as follows：

Step S3, opening power supply makes motor drive emery wheel rotation, and open water valve, passes water through water inlet and enters compression bar
It is interior and pass through osculum flow out.Ensure grind into have in the process water cool down and depositing dust；
Step S4 using an emery wheel of grinder, shakes the handle of grinder, emery wheel is made slowly to contact rock pillar to be ground
Cylindrical surface is simultaneously ground, until the cylindrical surface of rock pillar to be ground towards emery wheel is smoothed the rock pillar to be ground tentatively ground, institute
The ground flat obtained is vertical with the axis of rock pillar to be ground, and closes power supply and water valve；
The rock pillar to be ground tentatively ground is put into cutting machine and cut, obtains disk rock sample by step S5, disk rock sample
Cut surface is face to be polished.The thickness of the disk rock sample is slightly larger than required thickness（Generally 3 millimeters）Disk rock sample.Circle
The cut surface of disk rock sample is the end face I corresponding to the Brazilian disc of final machine-shaping, the ground flat polished on disk rock sample
It is the end face II corresponding to the Brazilian disc of final machine-shaping；
The positioning rock pillar for holding positioning component tightly is placed in the card slot of positioning base by step S6, and tightening a cap makes compression bar
Compress rock pillar to be ground；
Step S7 repeats step S3 and step S4, make to obtain on positioning rock pillar one it is parallel with the perpendicular of emery wheel
Ground flat；
The top brace ring for embracing sample component and bottom brace ring set are located at and embrace in sample hose clamp by step S8, and with armful sample component
Sample hose clamp is embraced to hold the side of disk rock sample tightly；
Step S9, by the end face I of the ground flat of disk rock sample, i.e. final molding Brazilian disc, direction positions rock pillar
On ground flat, the drag hook of top brace ring and the upper flower basket bolt for holding positioning component tightly is hung tightly, bottom brace ring is positioned with holding tightly
The drag hook of the lower flower basket bolt of component is hung tightly, and tightens flower basket bolt and lower flower basket bolt, makes the ground flat of disk rock sample
It is tightly attached on the ground flat of positioning rock pillar.The ground flat being held in position on rock pillar is parallel to emery wheel plane always；
Step S10 repeats step S3 and step S4, the parallel disk rock sample of two ground flats is obtained, so as to make disk
The flatness in two faces of rock sample is guaranteed.
A kind of Brazilian disc end face flatness device including holding positioning component tightly and embracing sample component, holds positioning component tightly
