Abstract
The present invention relates to a polishing technology and its equipment for small hole of crystal necklace. Said invention is characterized by using an extrusion grinding method to polish the small hole of tenuous crystal, whose diameter is below 1mm. Said invention uses a high pressure to force the lapping paste containing diamond powder to flow through the crystal hole at a high speed, and uses the borts suspended in the lapping paste to polish the internal surface of the small hole so as to raise its smooth finish.
Description
The present invention relates to a kind of glossing and equipment of small hole of crystal necklace.
Domestic crystal necklace manufacturer all adopts supercritical ultrasonics technology to get out the threading aperture at present, and the aperture is about 0.5～0.8 millimeter, 5～10 millimeters of Kong Changwei.But, cannot further polish because lack necessary Processes and apparatus.So the inner surface fineness of aperture is extremely low, the column that is white in color influences attractive in appearancely, becomes the direct obstacle of foreign exchange earning.
The object of the present invention is to provide a kind of glossing and equipment that makes the elongated aperture inner surface of crystal necklace obtain higher fineness.
Technical solution of the present invention:
A kind of small hole of crystal necklace glossing and equipment is characterized in that adopting the fluid abrasive method to polish aperture.Detailed process: will contain the end high pressure injection of the abrasive pastes of Buddha's warrior attendant powder from aperture, the other end flows out, and forms columnar fluid.The Buddha's warrior attendant powder particles that is suspended on the columnar fluid is close to little hole wall and is streaked because of the effect of pressure, and seemingly a flexible emery stick passes from aperture, thereby reaches the purpose of polishing.
For reaching the mirror finish requirement fast, so use the grade polished method.Promptly polish with thicker Buddha's warrior attendant powder abrasive pastes earlier, carry out the transition to meticulous Buddha's warrior attendant powder abrasive pastes then.
If the outlet pressure of aperture is zero in the process of lapping, very big pressure gradient will be formed.Big more at pressure, polishing effect for significantly, can cause horn-like aperture more.Therefore need to keep certain back pressure, slow down along the axial pressure gradient of aperture, to avoid horn-like aperture in the exit.
During processing crystal necklace aperture, the present invention adopts the crush and grind lathe, and oil cylinder becomes single cylinder by twin-tub about it, and jig is a swinging multistation formula, simultaneously many workpiece of clamping.
Crush and grind lathe of the present invention mainly by:
1, upper cylinder; 2, go up medium cylinder; 3, clamping plate; 4, lathe bed; 5, platen; 6, following medium cylinder; 7, locking fixture oil cylinder; 8, following oil cylinder; 9, lathe bed is formed.
Jig of the present invention mainly by: fixture 10, panoramic table 11, fixture 12, workpiece 13, sealing gasket 14, anchor clamps loam cake 15, anchor clamps base plate 16 are formed.
Further describe below in conjunction with accompanying drawing:
Accompanying drawing 1 is a crush and grind machine tool structure schematic diagram;
Accompanying drawing 2 is jig structural representations;
Accompanying drawing 3 is jig working state schematic representations.
As Fig. 1, the anchor clamps that workpiece to be processed is housed enter between the upper and lower medium cylinder automatically, and hydraulic oil enters locking fixture oil cylinder 7 from a hydraulic fluid port.Under the effect of pressure, drive clamping plate 3 and go up the together action downwards of medium cylinder 2, upper cylinder 1 by piston rod, until anchor clamps are locked.Hydraulic oil enters upper cylinder from the b hydraulic fluid port and promotes piston and move downward then, promotes the medium cylinder piston by connecting rod abrasive pastes are released from last medium cylinder 2, enters down medium cylinder 7 through small holes.Conversely, hydraulic oil enters down oil cylinder 8 from the d hydraulic fluid port, and piston moves upward, and promotes medium cylinder 6 down by connecting rod, with abrasive pastes through small holes in returning medium cylinder 2 again.Oil cylinder takes turns to work up and down, makes abrasive pastes come and go by polished aperture, finishes process.
As Fig. 2,3, improve working (machining) efficiency for realizing grade polished and process time and clamping time-interleaving, jig Design becomes the swinging multi-station clamp.Two fixtures 10,12 that distributing on the panoramic table, panoramic table can pivot, and fixture 10,12 is sent between the upper and lower medium cylinder in turn polished.Fixture can polish 50 clamping workpieces simultaneously.
The present invention is reasonable in design, has improved the fineness of small hole of crystal necklace inner surface, makes its endoporus smooth, attractive in appearance.
Claims (3)
1, a kind of small hole of crystal necklace glossing, it is characterized in that utilizing pressure to make containing grind the Buddha's warrior attendant powder the fluid high-speed high pressure by polished little internal surface of hole to obtain higher fineness, whole polishing divides two-stage, and the first order makes it reach △ 7～△ 8 with thick Buddha's warrior attendant powder fluid rubbing down; Meticulous Buddha's warrior attendant powder fluid rubbing down is adopted in the second level, makes it reach △ 10～△ 12.In the polishing process, be compressed the pressure that oil cylinder has left, to form polishing fluid certain " back pressure " in aperture exit.
2, a kind of pressure lapping machine, it is characterized in that lathe mainly by upper cylinder 1, go up medium cylinder 2, clamping plate 3, lathe bed 4, platen 5, down medium cylinder 6, locking fixture oil cylinder 7, oil cylinder 8, lathe bed 9 are formed down, oil cylinder becomes single cylinder by twin-tub up and down.
3, a kind of jig mainly is made up of fixture 10, panoramic table 11, fixture 12, workpiece 13, sealing gasket 14, anchor clamps loam cake 15, anchor clamps base plate 16.Anchor clamps are revolution multistation formula, many workpiece of clamping simultaneously.
