Description

Milling and grinding clamp for special-shaped lens

Technical Field

The utility model belongs to the technical field of the optical material processing, concretely relates to mill quick-witted anchor clamps, in particular to anchor clamps of dysmorphism lens appearance processing.

Background

The special-shaped lens is a lens with the shape of other than a circle, such as a square, an ellipse, a triangle or a polygon, the shape processing of the special-shaped lens cannot be realized by vice clamping or other mechanical clamping methods, because the clamping part at the edge of the lens cannot be processed, the production usually adopts a bonding method to bond the reference surface of a part on a designed clamp for processing, and the degumming treatment is carried out after the processing is finished.

Problems that can occur with conventional bonding: for example, a large amount of bubbles are easy to appear on the bonding surface, so that the bonding is not firm, the form and position tolerance of the processed surface is difficult to guarantee due to the uneven thickness of the bonding surface, the degumming treatment is not facilitated after the processing is finished, or the degumming time is long, and the like.

Disclosure of Invention

The utility model aims at overcoming a series of problems that the conventional bonding appears and providing a novel clamp with simple structure and convenient use.

In order to achieve the above purpose, the invention provides the following technical scheme:

the utility model provides a dysmorphism lens mills and grinds anchor clamps, includes the anchor clamps bonding member of cylindrical base and multiple shape, anchor clamps bonding member fixed connection is held in the base circular cross section, keeps away from the one side of connecting the base and is the anchor clamps bonding surface, be provided with the several recess on the anchor clamps bonding surface.

Preferably, the shape of the clamp bonding piece is rectangular, triangular, oval or any other irregular figure.

Preferably, the fixture bonding surface is provided with a plurality of regularly arranged rectangular grooves.

Preferably, a plurality of grooves which are arranged in a grid-shaped crossed manner are arranged on the bonding surface of the clamp.

Preferably, the depth of the groove is 1-3mm, and the width of the groove is 3-6 mm.

The utility model discloses an anchor clamps face of bonding designs into regular latticed to reduce the area of contact that the part bonded, appear the bubble when can avoiding bonding like this, unnecessary glue can overflow to the recess during the bonding, avoids glue film thickness inhomogeneous, secondly after processing is accomplished, and debonding agent can follow the bonding position that the recess got into the mid portion when degumming, can come unstuck fast.

Detailed Description

The following describes in detail preferred embodiments of the present invention with reference to the accompanying drawings.

Example 1

As shown in fig. 1-6, the milling fixture for the special-shaped lens comprises: the special-shaped lens milling and grinding machine comprises a base 1, wherein the base 1 is a cylindrical rotary body and is provided with an interface matched with various special-shaped lens milling and grinding processing machines; the clamp bonding piece 2 is fixedly connected with the base 1 and the clamp bonding pieces in different shapes, and the bonding pieces are respectively in various shapes such as rectangle, triangle, ellipse and the like; the surface far away from the connecting base is a clamp bonding surface, as shown in fig. 2, grooves 3 which are arranged in a grid-shaped cross mode are arranged on the clamp bonding surface, the grooves are rectangular, the depth of each groove is 1-3mm (preferably 2 mm), the width of each groove is 3-6mm (preferably 5 mm), a plurality of rectangular convex blocks correspond to the grooves, and the convex blocks are perpendicular to the clamp bonding surface.

Specifically, when a part is machined, a designed fixture is designed or selected according to the finished overall dimension of the part, a part reference surface is selected as a bonding surface, the part reference surface and the fixture bonding surface are preheated, a binder is heated, the binder is uniformly coated on the bonding surface after preheating, the part reference surface is pressed onto the fixture bonding surface, redundant binder can flow into the latticed grooves, the part is bonded on the fixture, the parallelism between the part reference surface and the bottom surface of the lens base needs to be kept by attention, after glue is solidified, the fixture is mounted on equipment for grinding, the machining is completed, and degumming agent is used for soaking for degumming.
