Description

Edging grinding wheel for optical lens

Technical Field

The utility model relates to an edging emery wheel for optical lens.

Background

In the process of processing optical spherical lens, a lens edging grinding wheel is generally required to process the biconvex lens so as to obtain the required diameter, chamfer and decentration of the lens. The working end of the double-convex lens edging grinding wheel is in a groove shape, and the shape of the working end is opposite to that of the edge of the double-convex lens. At present, the diamond layer of certain granularity has been electroplated to the recess type working face of whole lens emery wheel work end, adds the diamond layer on the concave groove and cuts the edge of lens during processing to obtain certain diameter, the center of chamfer and lens is inclined to one side, and the life-span on diamond layer receives certain operating time's restriction simultaneously, also can scrap after the diamond layer consumes exactly lens edging emery wheel, thereby causes the waste.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: the utility model aims at providing a can increase edging emery wheel for optical lens of same edging abrasive machining lens number.

The technical scheme is as follows: the utility model discloses an edging emery wheel for optical lens, the edging emery wheel is the annular structure that the center was equipped with the through-hole, and the main shaft of edging machine stretches into in the central through-hole and with central through-hole fixed connection; the annular structure comprises an inner ring and an outer ring, wherein the outer ring is provided with at least two grooves which are arranged in parallel along the circumferential direction, and the working surfaces of the grooves are coated with diamond layers.

Wherein, the width (thickness) of the annular structure along the extension direction of the inner ring to the outer ring is gradually reduced in the longitudinal direction.

Wherein 2-3 layers of diamond layers are laid on the working surface of the groove; the thickness of the diamond layer is determined by the diamond granularity, namely, one layer of the diamond layer is the grain size of diamond, 2-3 or more layers of diamond layers can be generally selected, the more the layers are, the better the durability is, but the lower the precision of the processed lens is, generally, the surface roughness of the processed lens is 1.6um, the granularity of the corresponding diamond is 400 meshes, and the larger the granularity of the diamond is, the larger the obtained surface roughness of the lens is.

The specifications of a plurality of grooves arranged in parallel are consistent, namely the width of the working surface of the groove, the depth of the groove and the thickness of the diamond layer on the working surface of the groove are consistent.

Wherein, a plurality of recesses that arrange side by side are equidistant arranges, are equipped with the joining region between the adjacent recess, and the general optional 1 ~ 2 millimeters of width of joining region mainly is considering joint strength, and under the condition that joint strength guarantees, the joining region can be narrower, and its purpose is exactly can arrange more recesses, improves edging emery wheel utilization ratio.

Wherein the cross section of the groove is wedge-shaped.

Has the advantages that: the utility model discloses set up the recess working face of a plurality of the same specifications at lens edging emery wheel working end, the recess working face equipartition of a plurality of the same specifications is arranged on edging emery wheel working end (outer loop), and after the diamond layer exhausts on first recess working face, uses second recess working face in proper order to increase the number of edging abrasive machining lens, improve the life of lens edging emery wheel, and then reduce cost, it is extravagant to reduce.

Drawings

fig. 2 is a schematic structural view of the working end.

Detailed Description

As shown in fig. 1-2, an edging wheel 1 for an optical lens according to the present invention has an annular structure with a through hole 2 at the center, and a main shaft of an edging machine extends into the through hole 1 and is fixedly connected to the through hole 2; the annular structure comprises an inner ring and an outer ring 5, the outer ring 5 is provided with at least two grooves 3 which are arranged in parallel along the circumferential direction, and a diamond layer is arranged on the working surface 6 of each groove 3. The width (thickness) of the annular structure in the longitudinal direction decreases gradually along the extension direction from the inner ring to the outer ring.

The specifications of the grooves 3 which are arranged in parallel are consistent, namely the width of the groove working surface 6, the depth of the grooves 3 and the thickness of the diamond layer on the groove working surface 6 are consistent; a plurality of grooves 3 which are arranged in parallel are arranged at equal intervals, and a connecting area 4 is arranged between every two adjacent grooves 3; the cross section of the groove 3 is wedge-shaped.

Will the utility model discloses on edging machine main shaft was installed to edging emery wheel 1 to adjust relevant copper pipe position, so that when the copper pipe cliied lens, all be located first recess within range when the edge that lens was processed removed, adjusted other relevant machine parameters, start the edging machine and carry out the edging processing to lens. After a plurality of lenses are machined, the diamond layer on the working surface of the first groove is exhausted, the left and right positions of the copper pipe are readjusted at the moment, so that when the copper pipe clamps the lenses, the machined edges of the lenses move left and right and are positioned in the range of the second groove, other related machine parameters are adjusted, and the edge grinding machine is started to continue to grind the lenses; according to the adjusting method, the diamond layers on the groove working surfaces which are not used subsequently of the edging grinding wheel 1 are used in sequence, and the edging processing is carried out on the lens until all the diamond layers on all the groove working surfaces on the edging grinding wheel 1 are exhausted, so that the number of the processed lenses is increased, the service life of the edging grinding wheel is prolonged, and the cost is reduced.
