Abstract
The utility model discloses a clamping device for objective glass lens polishing, wherein the clamping device for objective glass lens polishing can well guarantee that a push hole is located at the center of a clamping base and can improve production efficiency. The clamping device comprises the clamping base, wherein the clamping base is provided with at least three containing holes which are in central symmetry, every two adjacent containing holes have the same center distance, a fixture used for containing an objective glass lens is arranged in each containing hole, the bottom wall of each containing hole is provided with a buffer hole, the center of the reverse side of the clamping base protrudes outward to form a protruding part, and the end face of the protruding part is provided with a conical push hole matched with a pressure thimble used for pushing the clamping base. The clamping device for objective glass lens polishing improves production efficiency and well guarantees that the push hole is located at the center of the clamping base at the same, thereby well guaranteeing the polishing quality of the objective glass lens.
Description
Technical field
The utility model relates to for precision machined clamping device, refers more particularly to a kind of clamping device of object lens lens polishing.
Background technology
In the precision optical machinery process such as grinding, polishing, usually need special fixture to be clamped workpiece to be processed.At present, be exclusively used in the polishing clamping device of object lens eyeglass, its structure comprises: grip slipper and for placing the fixture of object lens eyeglass, the front central authorities of grip slipper offer the placement hole matched with described fixture, offer cannelure on the diapire of placement hole, be provided with O type circle in cannelure, the back side central authorities of grip slipper offer top wedge installing hole, be provided with the top wedge in the wedge installing hole of top, offer on the end face of top wedge and press hole for pushing up the taper top that the pressure thimble of pressing grip slipper matches.During actual the use, the object lens eyeglass that the grinding ware can only be opposite in described unique fixture at every turn carries out polishing, and production efficiency is lower; And, because the polishing clamping device in use needs to swing, this split-type structural of top wedge and grip slipper, can not guarantee well that pressure hole, top is positioned at the center of grip slipper, thereby the quality of finish of object lens eyeglass is impacted.
The utility model content
Technical problem to be solved in the utility model is: provide a kind of and can guarantee preferably that pressure hole, top is positioned at the center of grip slipper, the object lens lens polishing clamping device that also can enhance productivity.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of object lens lens polishing clamping device, comprise: grip slipper, offer at least three centrosymmetric placement holes on grip slipper, make adjacent in twos placement hole there is identical centre-to-centre spacing, be provided with the fixture of an arrangement object lens eyeglass in each placement hole, offer cushion hole on the diapire of placement hole, the back side mediad of grip slipper swells outward, form protrusion, offer on the end face of protrusion and press hole for pushing up the taper top that the pressure thimble of pressing grip slipper matches.
The height of described cushion hole for to increase by 1.2～1.5 millimeters on the basis of object lens lens edge thickness to be processed.
On described grip slipper in twos the centre-to-centre spacing between adjacent placement hole be 1.1～1.4 times of placement hole diameter; Be preferably 1.1～1.2 times.
Described outside protuberance is round table-like, forms the protuberance round platform.
The beneficial effects of the utility model are: owing to having offered at least three for settling the placement hole of object lens eyeglass fixture on grip slipper, make whole clamping device can clamp at least three object lens eyeglasses, grind ware and can carry out polishing to the object lens eyeglass at least three fixtures at every turn, thereby greatly improved production efficiency; In addition, the taper top presses hole directly to be opened in the back side of grip slipper, has guaranteed that well pressure hole, top is positioned at the center of grip slipper, thereby has guaranteed preferably the quality of finish of object lens eyeglasses.In addition, due to the back side of grip slipper, press outwards protuberance of place, hole offering the taper top, be round table-like, simultaneously, by controlling on grip slipper the centre-to-centre spacing between adjacent in twos placement hole, alleviated the gravity of grip slipper, saved raw material.

The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As Fig. 1, shown in Fig. 2, object lens lens polishing clamping device described in the utility model, comprise: grip slipper 1, offer three centrosymmetric placement holes 11 on grip slipper 1, make adjacent in twos placement hole 11 there is identical centre-to-centre spacing, be provided with the fixture 2 of an arrangement object lens eyeglass in each placement hole 11---shown in Figure 4, offer cushion hole 12 on the diapire of placement hole 11, as shown in Figure 3, the back side mediad of grip slipper 1 swells outward, be round table-like, form protuberance round platform 10, outwards protuberance swells on the end face of round platform 10 and offers and press hole 13 for pushing up the taper top that the pressure thimble of pressing grip slipper 1 matches, in the present embodiment, the height of described cushion hole 12 for to increase by 1.2～1.5 millimeters on the basis of object lens lens edge thickness to be processed, on described grip slipper in twos the centre-to-centre spacing between adjacent placement hole be 1.1～1.4 times of placement hole diameter, be preferably 1.1～1.2 times.
During actual the use, usually be placed with O type circle in the cushion hole 12 on grip slipper 1, be placed with successively the object lens neonychium in the inner chamber 20 of fixture 2 and need the object lens eyeglass of processing.Because the aspect ratio of cushion hole 12 is more suitable, make the O type that is placed in cushion hole 12 enclose resiliency supported effect preferably.
