Abstract
The utility model discloses a kind of lower millstone of twin grinder to adjust structure, include the lower millstone and mill bracket of annular, lower millstone is fixed on the top of mill bracket, including three groups of adjusting screws by a plurality of fixing screws, and every group of adjusting screw includes screw and locking nut；Mill bracket includes three screwed holes, and screw screws in screwed hole from bottom to up, and the front end of screw withstands on the bottom surface of mill.The utility model ensures that upper millstone is in parastate with lower millstone during work by three groups of adjusting screws.It is damaged to exempt to have kept away the ultra-thin brittle workpiece caused by mill is mutually inclined.
Description
Technical field
It the utility model is related to twin grinder, more particularly to a kind of lower millstone adjustment structure of twin grinder.
Background technology
Twin grinder is highly suitable for being ground while upper and lower two parallel end faces of hard brittle material thin type precision component
And polishing, the very high thin part of flatness, equal thickness and roughness requirements can be processed, so in optics and semiconductor
The manufacture field of material is widely applied.
When the upper millstone of twin grinder and not parallel lower millstone, upper millstone locally first contacts with workpiece, until upper millstone
It is overall all to push in place.When processing ultra-thin fragile material, possibility upper millstone is only pressed onto workpiece during upper millstone pushes
Sub-fraction, cause workpiece local pressure excessive and cause the damage of workpiece.But the lower abrasive disk of traditional twin grinder
There is no the adjustment structure of the upper and lower mill depth of parallelism, therefore when having beat, upper millstone and not parallel lower millstone because of lower millstone,
Collimation can not be carried out by adjusting lower millstone.
The content of the invention
The technical problems to be solved in the utility model is to provide a kind of pair that can adjust lower millstone and the upper millstone depth of parallelism
The lower millstone adjustment structure of surface grinding.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is a kind of lower mill of twin grinder
Disk adjusts structure, includes the lower millstone and mill bracket of annular, and lower millstone is fixed on mill bracket by a plurality of fixing screws
Top, including three groups of adjusting screws, every group of adjusting screw include screw and locking nut；Mill bracket includes three screw threads
Hole, screw screw in screwed hole from bottom to up, and the front end of screw withstands on the bottom surface of mill.
Above-described lower millstone adjusts structure, and mill bracket includes annular pallet, wheel hub, up-small and down-big conical disc and
Plural block riser；Annular pallet, wheel hub and conical disc are coaxial, and annular tray arrangement is in the top of conical disc, annular pallet and cone
Shape disk is connected by riser, circumferentially spaced arrangement of the plural block riser along annular pallet；Wheel hub is arranged in conical disc small end
Portion；Lower millstone is fixed on the top of annular pallet by a plurality of fixing screws, and described screwed hole is located on annular pallet.
Above-described lower millstone adjusts structure, and plural block riser is uniform along the circumference of annular pallet.
Above-described lower millstone adjusts structure, including a plurality of alignment pins, alignment pin are up big and down small ladder pins；Under
Mill and annular pallet respectively include dowel hole；Positioned between lower millstone and annular pallet by alignment pin and dowel hole.
Above-described lower millstone adjusts structure, and the wheel hub of mill bracket is fixed on the vertical shaft of twin grinder.
The utility model ensures that upper millstone is in parastate with lower millstone during work by three groups of adjusting screws.Exempt to keep away
Ultra-thin brittle workpiece is damaged caused by mill is mutually inclined.

Embodiment
The utility model embodiment twin grinder lower millstone 1 adjusts structure as shown in Figures 1 to 7, including under annular
Mill 1, mill bracket 2 and three groups of adjusting screws.
Mill bracket 2 includes annular pallet 201, wheel hub 202, up-small and down-big conical disc 203 and 6 pieces of risers 204.Annular
Pallet 201, wheel hub 202 and conical disc 203 are coaxial, and annular pallet 201 is arranged in the top of conical disc 203, annular pallet 201 with
Conical disc 203 is connected by riser 204, and 6 pieces of risers 204 are uniform along the circumference of annular pallet 201.
The wheel hub 202 of disc holder is arranged in the middle part of the small end of conical disc 203, and mill bracket 2 is fixed on double by wheel hub 202
On the vertical shaft 3 of surface grinding.
Lower millstone 1 and annular pallet 201 respectively have three dowel holes, and the dowel hole of lower millstone 1 is more than annular pallet 201
Dowel hole.Alignment pin 4 is up big and down small ladder pin, and the upper and lower side of alignment pin 4 inserts the dowel hole of lower millstone 1 respectively
With the dowel hole of annular pallet 201, the positioning between lower millstone 1 and annular pallet 201 is realized.
Lower millstone 1 is fixed on the top of annular pallet 201 by three fixing screws 5.Every group of adjusting screw includes one
Screw 6 and a locking nut 7；There are three screwed holes on annular pallet 201, screw 6 screws in screwed hole, screw from bottom to up
6 front end withstands on the bottom surface of lower millstone 1.
When finding that lower millstone 1 is not parallel with upper millstone, the lock of three fixing screws 5 and three groups of adjusting screws is unclamped first
Tight nut 7, adjusts the depth of parallelism of lower millstone 1 and upper millstone by unscrewing or tightening screw 6, fastens three after adjusting respectively again
The locking nut 7 of individual fixing screws 5 and three groups of adjusting screws.
The utility model above example can ensure that upper millstone is in parastate with lower millstone by adjustment.Exempt to keep away
The inclined situation of mill occurs during processing, can process ultra-thin fragile material very well, avoids because because tilting when upper millstone pushes
The breakage of ultra-thin brittle workpiece is caused in lower millstone.
