Description
Technical field
The utility model is related to the Excircle machining field of pole class product, more particularly to a kind of for pole Excircle machining
Frock.
Background technology
Because synthetic sapphire has hardness high, wear-resistant, linear expansion coefficient is small, the features such as acid-alkali-corrosive-resisting, and has
Good optical property, extensively using various optical devices.But, because synthetic sapphire has hardness high（9 grades of Mohs, only
Inferior to rough diamond）, fragility it is big, the characteristic such as crystalline anisotropy, its difficulty of processing is also quite big.
Conventional jewel pole Excircle machining method is utilized in the middle of upper and lower mill plus one piece of dividing plate frock, and dividing plate is opened
Have uniform rectangle skewed slot, see accompanying drawing 7,8, product is lain in groove, by main shaft drive lower millstone rotate so that drive every
Plate and product are rotated.
By kinetic theory it is understood that this is accomplished by upper millstone fixes, otherwise product can not fully revolve in dividing plate
Turn, tangent plane phenomenon can have been caused, circularity is poor.Original upper millstone fixed form is to curve a cleek with external diameter 4mm iron wires
8, one end is fixed on lathe, and the other end hangs over cleek at the notch of upper millstone 1, and upper millstone 1 is held, and fixes upper millstone
Do not rotate, machining sketch chart is shown in accompanying drawing 9.
The shortcoming of original processing method：First, upper millstone is caught on iron wire hook, may after the iron wire corrosion of time length
It can break, cause unsafe factor and product rejection.2nd, operative employee waits to fill, it is necessary to hold upper millstone with hand when bed is started shooting
Divide to rotate and go to hang iron wire hook, influence operation continuity again.3rd, upper millstone is tangled with cleek, without lower pressure, in rotation process
Middle upper millstone has bounce, causes the unstable rotation of product.
The content of the invention
The purpose of this utility model is that there is provided a kind of work for pole Excircle machining in view of the shortcomings of the prior art
Dress, which raises stability during upper millstone rotation, and conveniently operation, improve safety and practicality.

Provided with positioning hole, the lower surface of the upper millstone is provided with positioning core axle, and the positioning interporal lacuna for being provided with dividing plate coordinates,
The thimble lower end is respectively provided on two sides with section, forms positioning step.
The frock hole is flat hole.Preferably, the frock hole is mounting hole.The two ends of mounting hole are semi arches, middle
It is parallel plane.Certainly, frock hole can also be using rectangular opening etc..
The axial line of the thimble passes through the axial line of the positioning core axle of upper millstone.
The axial line of the positioning core axle of upper millstone is located at always with the axial line for driving the main shaft of lower millstone rotation
On line.
The upper millstone is provided with thimble groove, and the bottom surface of the thimble groove is less than the bottom surface of neck, and the thimble passes through clamp
The frock hole being provided with, stretches into the bottom surface in thimble groove with thimble groove and contacts.Preferably, the thimble groove is closed slot.Preferably,
The thimble groove is circle.
The left and right ends of the neck extend through upper millstone, form open slot.Preferably, the neck is bar shaped.
The upper end of the upper millstone is provided with boss, and the upper surface of the boss is provided with neck, the left and right ends of the neck
Boss is extended through, open slot is formed.Preferably, the boss is cylinder.
The stopper slot forms groove axially through dividing plate.
The stopper slot is rectangle, and two between two short side midpoints of each rectangle stopper slot and dividing plate central point are straight
Angle between line is equal, and more than zero.Stopper slot is closed slot.
Some rectangle stopper slots are evenly distributed on dividing plate, the folder between the short side center line of adjacent rectangle stopper slot
Angle is equal, and the midpoint of the same short side of each rectangle stopper slot is located on same circumference.
The utility model this have the advantage that：Due to the upper millstone of the frock of the present utility model for pole Excircle machining
Upper end be provided with neck, a clamp is arranged in the neck that upper millstone is provided with, and forms circumferentially positioned between upper millstone, the card
Son is provided with the frock hole for being used for coordinating with thimble, and the frock hole that the thimble is provided with through clamp is contacted with upper millstone, the top
Pin lower end is respectively provided on two sides with section, the planar side of the sections of the thimble both sides respectively with the two long sides in clamp frock hole
Wall gap coordinates, and makes to form circumferentially positioned between thimble and clamp.The utility model coordinates screens frock to block by thimble
Mill, makes upper millstone fixing-stable；Secondly in upper and lower product, lathe only need to be switched, without going to take away iron wire hook again, is reduced
Operating process；In addition, being worn and torn or the caused potential safety hazard of corrosion by the use of screens frock, then without iron wire.Processed
Cheng Zhong, gem products can be rotated freely fully, and the circularity over tolerance of product, or processing table will not be caused because of the shake of upper millstone
Face, which is produced, can reverse end for end and replace in defect, Product processing, and product cylindricity is all right, it is adaptable to which many specifications, high-volume add
Work.
