In order to solve the technical problem, the utility model discloses a technical scheme does: the utility model provides an optical lens piece grinds anchor clamps, it includes pressure head and anchor clamps to grind anchor clamps, the circumference direction of pressure head is provided with first limit flange, through an annular rubber circle is installed to first limit flange, the upper surface laminating of anchor clamps has the glued membrane, through glued membrane and annular rubber circle contact, the lower surface of anchor clamps laminates in proper order has glued membrane, the cotton pad of bubble, through the cotton pad contact lens of bubble.

As the preferred proposal of the utility model, the glue film is a Teflon glue film.

As the preferred scheme of the utility model, the pressure head is provided with the installation screw hole that is used for connecting the drive pivot.

As the preferred scheme of the utility model, anchor clamps are provided with and are used for spacing second limit flange to the lens.

As the preferred scheme of the utility model, the pressure head still is provided with and is used for radiating louvre.

The beneficial effect of adopting above-mentioned technical scheme is: the adhesive film is attached to the top surface of the clamp, so that the centering of the clamp during grinding of the lens is enhanced, and the grinding is more stable; teflon glue film is selected for use as the glue film, Teflon film toughness is good, hardness is enough to reach the surface smooth, the lower surface laminating of anchor clamps has the glued membrane, through foam-rubber cushion and lens contact, because the good frictional force of glued membrane smoothness is little for lens and bubble cotton pad rotate simultaneously and reduce the lens friction, have improved the quality of polishing of lens.

In the figure, 1, a pressure head; 2. an annular rubber ring; 3. a clamp; 4. a lens; 5. a glue film; 6. soaking a cotton pad; 7. a first stop flange; 8. a second position-defining flange; 9. and installing a threaded hole.

Detailed Description

The following describes the present invention with reference to the accompanying drawings. It should be noted that the description of the embodiments is provided to help understanding of the present invention, but the present invention is not limited thereto. In addition, the technical features related to the embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.

According to fig. 1, this embodiment provides an optical lens grinding fixture, grinding fixture 3 includes pressure head 1 and anchor clamps 3, the circumferential direction of pressure head 1 is provided with first limit flange 7, through an annular rubber circle 2 is installed to first limit flange 7, the upper surface laminating of anchor clamps 3 has glued membrane 5, through glued membrane 5 and annular rubber circle 2 contact, the lower surface of anchor clamps 3 has also laminated glued membrane 5, through glued membrane 5, foam-rubber cushion contact lens 4. The utility model discloses a lower surface of lens 4 is placed on the roating seat, is provided with the abrasive surface that matches with the convex surface radian of lens 4 on the roating seat, and abrasive surface and 4 surface contact of lens grind lens 4 at the continuous rotation in-process through the roating seat for thereby the lower surface of lens 4 produces the effect that the friction played abrasive machining with the abrasive surface, with the lower surface polishing of lens 4. The existing lens 4 clamp 3 is not provided with a glue film 5, and is only contacted with the lens 4 through a sponge pad, the friction force between the foam pad 6 and the clamp 3 is larger than that between the foam pad 6 and the lens 4, so that the upper surface of the lens 4 and the clamp 3 are easy to generate larger abrasion, and the grinding effect of the lens 4 is seriously influenced. And the utility model discloses a lower surface laminating of anchor clamps 3 has glued membrane 5, through foam-rubber cushion and the contact of lens 4, because the good frictional force of 5 smoothness of glued membrane is little for at the grinding in-process, lens 4 and bubble cotton pad 6 can rotate simultaneously basically in order to reduce the friction between lens 4 and the foam-rubber cushion, have improved the quality of polishing of lens 4.

In order to obtain a more uniform receiving effect for the lens 4, the adhesive film 5 is preferably a teflon adhesive film 5. After the grinding time is long, the pressure head 1 can generate heat, and the Teflon adhesive film 5 has the advantage of high temperature resistance and is not easy to melt.

Pressure head 1 is provided with the installation screw hole 9 that is used for connecting the drive pivot, and installation screw hole 9 is used for connecting the actuating lever of machine, presses on lens 4 through the actuating lever is automatic, prevents that lens 4 from deviating at the grinding in-process, and its pressure head 1 only plays spacing effect with the composite set of anchor clamps 3 to lens 4, and real grinding is accomplished through the abrasive surface on the roating seat.

In order to prevent the lens 4 from deviating during grinding, the fixture 3 is preferably provided with a second stop flange 8 for stopping the lens 4.

Because in the grinding process, a large amount of heat can be accumulated in the pressure head 1, and the heat is dissipated through the heat dissipation holes arranged in the pressure head 1.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. It will be apparent to those skilled in the art that various changes, modifications, substitutions and alterations can be made in the embodiments without departing from the principles and spirit of the invention, and the scope of the invention is to be accorded the full scope of the claims.
