Description
Technical field
The utility model relates to a kind of optics clamp for machining, especially a kind of lens milling anchor clamps, and specifically a kind of vacuum of convenient mounting and clamping is inhaled lens milling anchor clamps.
Background technology
At present, conventional lens milling anchor clamps are that elastic clip is enforced the law, the shortcoming of the method is that lens need to have certain limit thick, for the lens clamping without gripper edge, must adopt bonding method make lens thickness increase edge thickness could clamping processing, often eccentric situation is more serious by eyeglass that the method processes.
Summary of the invention
The purpose of this utility model is for clamping inconvenience in the existing sharp limit lens milling processing, need clamping processing to cause off-centre larger behind the margo, affect the problem of product quality, design a kind of vacuum that is applicable to various marginal texture lens and inhale lens milling anchor clamps.
The technical solution of the utility model is:
A kind of vacuum is inhaled lens milling anchor clamps, it comprises jig main body 4, this jig main body 4 links to each other with machine tool chief axis connector 6 by connecting bolt 3, the center that it is characterized in that described jig main body 4 is hollow structure, this hollow structure is connected with vacuum passage on the machine tool chief axis connector 6, the end surface shape of jig main body 4 and processed lens back side shape match, be set with the centring ring 2 that makes processed lens centre and jig main body 4 centres at jig main body 4, centring ring 2 is provided with a location structure 7 that makes processed lens position, centring ring 2 is provided with internal thread, jig main body 4 is provided with the external screw thread that matches, thereby centring ring 2 is contained in by its internal thread rotation on the external screw thread of jig main body 4 centring ring is fixed in the milling process on jig main body 4 to prevent processed lens injury.
Between the faying face of described jig main body 4 and machine tool chief axis connector 6, add sealing ring 5.
Described location structure 7 is groove or removable positioning sliding block, and when described location structure 7 was groove structure, the diameter of groove should be complementary with the external diameter of lens, and when described location structure 7 was the positioning sliding block structure, each positioning sliding block should be mobile simultaneously around the center of circle.
The beneficial effects of the utility model:
1. the back side of anchor clamps end face of the present utility model and part to be processed matches, and better eyeglass is played the milling supporting role.
2. anchor clamps of the present utility model are adjustable, can get the precision adjustment by clamping fixture seat, so that eyeglass is coaxial with work spindle.
3. good airproof performance of the present utility model, whole anchor clamps are integral type, just can avoid vacuum leak by a sealing ring.
4. part centring ring of the present utility model is convenient for changing part, and centring ring and jig main body are threaded connection avoids that centring ring moves and injures eyeglass in the lens grinding and milling process.
5. the utility model adopts vacuum suction eyeglass, the milling of applicable featheredge lens.
Description of drawings
Fig. 1 is lens installment state schematic diagram of the present utility model.
Fig. 2 is lens machining state schematic diagram of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further described.
Shown in Fig. 1-2.
A kind of vacuum is inhaled lens milling anchor clamps, and it comprises jig main body 4, and this jig main body 4 links to each other with machine tool chief axis connector 6 by connecting bolt 3, adds sealing ring 5 between the faying face of jig main body 4 and machine tool chief axis connector 6; The center of described jig main body 4 is hollow structure, this hollow structure is connected with vacuum passage on the machine tool chief axis connector 6, the end surface shape of jig main body 4 and processed lens back side shape match, be set with the centring ring 2 that makes processed lens centre and jig main body 4 centres at jig main body 4, centring ring 2 is provided with a location structure 7 that makes processed lens position, as shown in Figure 1, centring ring 2 is provided with internal thread, jig main body 4 is provided with the external screw thread that matches, thereby centring ring 2 is contained in by its internal thread rotation on the external screw thread of jig main body 4 centring ring is fixed in the milling process on jig main body 4 to prevent to processed lens injury, as shown in Figure 2.
During implementation, location structure 7 can adopt the groove structure shown in Fig. 1,2, and the diameter of groove should be complementary with the external diameter of lens.Location structure 7 also can be designed to be similar to the structure of lathe chuck, namely at the end face of centring ring movably positioning sliding block is installed, and each positioning sliding block should be mobile simultaneously around the center of circle.
Of the present utility modelly easy to usely be:
Unclamp the screw thread of centring ring 2 with jig main body 4 during eyeglass the location, utilizes the interior locating surface of centring ring 2 at the outer axial face upward sliding of jig main body 4, is positioned over eyeglass 1 in the centring ring 2 and on the anchor clamps end face time, activates vacuum, with eyeglass absorption, such as Fig. 1.
After the eyeglass absorption centring ring is glided along jig main body, and be threaded connection and be fixed on the anchor clamps, as shown in Figure 2, avoid in the lens grinding and milling process centring ring to move and injure eyeglass.
The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
