A kind of quartz plate outer circle sander
Technical field
The present invention relates to peripheral milling equipment technical field, specially a kind of quartz plate outer circle sander.
Background technology
General cylindrical grinder, mostly uses greatly centreless grinding, and small pieces, especially metal material are not afraid of collision and be not afraid of
For the workpiece of damage, effect is very good.If it is somewhat larger workpiece, the equipment price of this grinding machine is just very high, for
Product that is frangible, should not colliding, such as quartz plate, monocrystalline silicon, it is necessary to special clamping, positioning device.Such as:Application No. is
A kind of monocrystalline silicon rounding device described in 200820168952.4 Chinese utility models, including lathe body, driving device, diamond dust
One end of wheel, tailstock, single crystal silicon product, the driving device is equipped with main folder disk, and auxiliary is equipped on the same axis with main folder disk
Chuck, main folder disk, auxiliary chuck are smaller than the outer diameter of single crystal silicon product with outer diameter of the collet in working condition.Its shortcoming is that should
To outer sputtering after column class workpiece can only be clamped in device, and clast rebounds with bed body in polishing, processing environment is influenced.
Invention content
It is an object of the present invention to provide a kind of quartz plate outer circle sanders, have polishing effect good, reduce clast and fly
The advantages of splashing.
The present invention above-mentioned technical purpose technical scheme is that:A kind of quartz plate outer circle polishing
Machine, including clamping device, grinding device and positioning device, the grinding device include the polishing branch of grinding wheel, the installation grinding wheel
The lower section of the polishing motor of frame and driving grinding wheel rotation, the grinding wheel is equipped with collecting box, and the clamping device includes being clamped in stone
The clamping disk of English piece two sides and for install be clamping disk grip slipper, the grip slipper is arranged in the positioning device,
The clamping disk is to be rotatably installed on grip slipper, and the clamping disk includes active clamping disk and driven clamping disk, the active
Clamping disk is driven by driving motor and is rotated, and the driven clamping disk turns by the way that synchronizing device is synchronous with the holding of active clamping disk
Dynamic, the rotation direction of the clamping disk is identical as the rotation direction of the grinding wheel, and the clamping disk is intermittent rotation;It is described
The pivot center of clamping disk is parallel with the pivot center of the grinding wheel, and the center of rotation of the clamping disk turns to the grinding wheel
The line at dynamic center, with -60 ° at 45 ° of angle of horizontal plane shape;The outside diameter of the clamping disk is less than quartz plate around the folder
Hold minimum outside diameter when disk pivot axis.
Due to clamping disk in the present invention center of rotation to the grinding wheel center of rotation line, formed with horizontal plane
45 ° -60 ° of angle wherein this angle is grinding wheel and the quartz plate line of centres of clamping disk and grinding wheel and level in the state of polishing
The angle that face generates so that for grinding wheel in polishing, the instantaneous of abrasive dust flies out direction as perpendicular to the center of rotation of clamping disk to institute
The line of the center of rotation of grinding wheel is stated, i.e. the instantaneous direction that flies out of abrasive dust forms 30 ° -45 ° of angle with horizontal plane, can be effective
The rebound height of after abrasive dust enters in collecting box and collecting box bottom is reduced, rather than in the prior art with perpendicular to horizontal plane point
Direction flies into collecting box, and direction acceleration of gravity direction vector overlaps, and it is maximum value to make speed of the abrasive dust in rebound, and rebound is high
Degree is also maximum value, is easy to sputter collecting box;And clamping disk is the polishing time that intermittent rotation can provide abundance, is beaten
It is more preferable to grind effect, while active clamping disk and driven clamping disk rotate synchronously, and prevent active clamping disk and slave clip on startup
It holds disk and will produce instantaneous relative rotation and the surface of destroying quartz plate.
Preferably, the clamping disk often rotates central angle when being 15 ° -30 °, clamping disk pause rotation time 0.5-
1 second.

Dynamic spur gear is connected by drive link to be kept rotating synchronously.
Preferably, the axial force direction that the Helical gear Transmission component generates is to be directed toward actively to be clamped by driven clamping disk
Disk.Quartz plate can be clamped always in bruting process by the axial force.
Preferably, the clamping face of the clamping disk is equipped with sucker.The sucker is plastic vacuum sucker, due to quartz plate table
Face is smooth, is easy to be adsorbed.
Preferably, the grip slipper is equipped with Mobile base, the Mobile base is slidably connected on the grip slipper, described
Driven clamping disk is mounted on the Mobile base, keeps the driven clamping disk separate or close to described by sliding the Mobile base
Active clamping disk.
Preferably, the Mobile base is connected with the pushing component for pushing its sliding.
Preferably, the drive link is telescopic structure, including the sleeve and loop bar that mutually socket-connect, in the sleeve and
Strip is equipped on the outside of the loop bar, the strip prevents the sleeve from being rotated along the transmission rod axis relative to the loop bar.
Preferably, the positioning device includes the longitudinal register component moved along the clamping disk axis direction and vertical
In the located lateral component of clamping disk axis direction movement, the longitudinal register component includes sliding over each other the first of connection
Slide and second slide, the second slide are equipped with the first drive rod, and the first slide is equipped with and first driving
The first drive block that bar is threadedly coupled, the located lateral component include slide over each other the third slide and the 4th slide of connection,
4th slide is equipped with the second drive rod, and the third slide is equipped with second be threadedly coupled with second drive rod
Drive block, the second slide are fixed on the third slide.
Preferably, the lower section of the grinding wheel is equipped with collecting box, the collecting box is equipped with flare openings, the collecting box
Interior be equipped with is located at the rebound surface below being open, in the center of rotation to the rotation of the grinding wheel of the rebound surface and the clamping disk
The line of the heart forms 60 ° -80 ° of angle, and the right opposite of the rebound surface sets buffering suface, and the buffering suface is equipped with and is spaced apart
Barrier plate.
The collecting box can further decrease the rebound height of abrasive dust, and Anti-splash effect is more preferable.
Beneficial effects of the present invention:The present invention can effectively reduce anti-with collecting box bottom after abrasive dust enters in collecting box
Bullet height, Anti-splash effect is good, and clamping disk is the polishing time that intermittent rotation can provide abundance, and polishing effect is good,
Simultaneously quartz plate firm grip, protect quartz plate surface not to be worn.
