Description

The jewel grinder

One, technical field

The utility model relates to a kind of grinder, particularly a kind of jewel grinder.

Two, background technology

Traditional jewel grinder mainly contains homemade anistree hand (single pole) single-deck machine, three tractor driver's double plate machines that single head tractor driver single-deck machine that produce in Taiwan and Korea S produce.Preceding two kinds of types are single pole single-deck structures, can only grind a stone base at every turn, 3-4 the jewel base of naming a person for a particular job grinds on mill bar (anistree hand or single head tractor driver) the dependence column, can not read the grinding angle, grind and to put down former mill bar behind the plate face and get new mill bar again, the mill bar that the same plate face has ground accumulates to a great deal of back (as 100) and just shuts down the replacing mill and (as pull down the water mill dish, load onto refiner discs), and then carry out the grinding of second plate face, general jewel is the rarest ten plate faces, grind 100 jewels so and will shut down and change dish 30 times, taking and placing mill bar 3000 times, yield poorly, of poor quality; And three tractor driver's double plate machines are still jewel of mill at every turn, and two mill three process are water mill list usefulness, finish grind, polish shared, the polishing micro mist of costliness must be erased a part when causing polishing, though quality makes moderate progress, output is still low, has also increased cost.

Three, summary of the invention

The purpose of this utility model provides and a kind ofly can overcome that the conventional gemstone grinder yields poorly, the jewel grinder of of poor quality, shortcomings such as power consumption is big, cost height.

Jewel grinder of the present utility model, comprise cabinet, motor, transmission device, mill and combination mill bar, it is characterized in that having on the motor plane bearing coaxial with it, one columniform rotary drum is arranged on the plane bearing, the rotating shaft of motor is stretched into rotary drum from the bottom, be connected with driving wheel, the driven pulley that drives three mills is contained in the columned rotary drum, be connected with driving wheel by transmission mechanism, article three, driven shaft stretches out the rotary drum top, connect mill, the handwheel that stretches out the cabinet top is equipped with in rotary drum top and electrical axis corresponding position, and cabinet has the arc window greater than semicircle.Three mills that the utility model jewel grinder uses are respectively water mill dish, refiner discs, polishing disk.

The combination mill bar of the utility model jewel grinder props up the mill bar for the 5-7 that equidistantly installs side by side, and the mill bar is enclosed within the mill bar axle, and mill bar axle suit again grinds in the bar axle bed; Synchronizing wheel is equipped with in every mill bar axle upper end, and there is chuck nut the lower end, all synchronizing wheels and a band engagement synchronously; The mill bar that wherein is contained in mill bar axle bed one end is main mill bar, extend to form a tail on its mill bar is axial, big plate face wheel of closed assembly and platelet face wheel on synchronizing wheel, eight holes are equidistantly opened in big plate face wheel outer ring, inner ring is not equidistantly opened eight holes, by platelet face wheel locating pin and the engagement of platelet face wheel, the hole of outer ring and the engagement of plate face locating pin, platelet face wheel has key to become axial sliding fit with the axle tail, and by compression spring location, its mill bar axle bed one side is hinged with slide block, and slide block set is in slide block slot, and a push rod is arranged at the slide block bottom, the slide block slot back side connects angled arc telescopic mast, insert in the telescopic chute arc telescopic mast bottom, and the telescopic chute upper end is fixed on the cabinet panel, and the lower end is stretched in the cabinet.

Before using the utility model jewel grinder to produce, must prepare the mill bar that sufficient amount has glued the jewel base, the angulation posts of will stretching is pulled to scale and is 90 ° and locates and fixing, pulling mill bar axle bed makes into horizontal, unclamp chuck nut and insert the mill bar, twisting the unlikely mill bar of chuck nut slightly deviates from, put down mill bar axle bed, make all mill bars perpendicular on the refiner discs of grinding in the window, the jewel base of adjustment mill rod end, stone base end face is all coincide with refiner discs, and the tightening chuck nut is coated suitable Dormant oils and micro mist on refiner discs then.

During face grinding, the right hand holds up slide block makes the stone base slightly from refiner discs, starter motor, unclamp handwheel and make the water mill dish align window, make the mill water flowing with pin after, the right hand puts down slide block gently, the stone base is ground on the water mill dish, time is controlled at 1-2 between second (specifically should test the back determines), and the mill Pitot plays slide block makes stone base leaving water mill face, and loose pin is cut off the water supply.The pine left hand makes refiner discs align window, put down slide block gently, make stone base correct grinding on dish, the time is controlled at 1-2 between second (definite through testing), and the mill Pitot plays slide block, the stone base is slightly from refiner discs, loose again left hand wheel makes polishing disk align window, puts down slide block and makes the polishing on dish of stone base, and come back rotation handwheel with left hand this moment, make have an appointment on dish the moving back and forth of 2cm of stone base, the time is still at 1-2 between second (definite through testing).The mill Pitot plays slide block, and the stone base has been finished water mill, correct grinding and the polishing three process of end face.

During the mill side, pushing angulation posts makes and carves the angle and align first plate face design angle of jewel and fixing, left hand unclamps and makes the water mill dish align window, use the pin water flowing, the right hand puts down mill bar axle bed gently, make first plate face water mill of stone base side, time 1-2 second, before being milled to stop screw on the bar axle bed and putting in place a little the time mention mill bar axle bed rapidly, after the pine pin is cut off the water supply, left hand unclamps handwheel makes refiner discs align window, and the right hand puts down mill bar axle bed the stone base is finish grinded, and the time is still 1-2 second, a small amount of stock removal that stop screw is remaining, grind off 80-90% during correct grinding, the right hand holds up mill bar axle bed, makes the stone base slightly from mill, left hand unclamps handwheel polishing disk is aligned window, the right hand puts down mill bar axle bed, makes the polishing of stone base, time 1-2 second, left hand turns handwheel back and forth, make polishing disk do back and forth moving of about 2cm, the grinding allowance of stone base all grinds away when polishing, and the plate face promptly obtains glittering luminosity.A plate face 3-6 consuming time promptly finishes water mill, correct grinding, polishing three process second.After this as long as adjustment two plate faces wheel and relevant angle repeat aforesaid operations, can finish the grinding of other plate faces, until obtaining whole ground backs jewel finished product.

Use jewel grinder of the present utility model, per hour can grind out the high-quality jewel more than 500.

Jewel grinder of the present utility model three dish interlocks, many bars combinations, can obtain when grinding various jewel that output height, quality are good, power consumption less, effect that cost is low, and have advantage easy to manufacture, easy to operate.
