Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
In description of the present utility model, it should be noted that, term " on ", D score, "left", "right", " top ", " end ", " interior ", the orientation of the instruction such as " outward " or position relationship be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of the device of instruction or hint indication or element must have specific orientation, with specific azimuth configuration and operation, therefore can not be interpreted as restriction of the present utility model.
In description of the present utility model, it should be noted that, unless otherwise clearly defined and limited, term " installation ", " connection " should be interpreted broadly, and such as, can be fixedly connected with, also can be removably connect, or connect integratedly; Can be mechanical connection, also can be electrical connection; Can be direct connection, also can be indirectly connected by intermediary, can be the connection of two element internals.For the ordinary skill in the art, the concrete meaning of above-mentioned term in the utility model can be understood depending on concrete condition.
In addition, in description of the present utility model, except as otherwise noted, the implication of " multiple " is two or more.
As shown in Fig. 1 ~ 7, a kind of L-type ZnSe that the present embodiment provides turns to the clamp for machining of prism to comprise elasticity profiling jig body 1, clamp bottom board 2, hold-down screw 3, pinching screw 4, Upper gasket 5, lower gasket 6.
Particularly, elasticity profiling jig body 1 hold-down screw 3 is fixed on clamp bottom board 2, clamp bottom board 2 hold-down screw 3 is fixed on fine turning lathe index table, after turning to upper and lower two non-operative end surface of prism workpiece and Upper gasket 5 and lower gasket 6 two panels pad compression fit, interference to embed on elasticity profiling jig body 1 between lower claw, recycling pinching screw 4 adjusts upper and lower two pawl gaps, fixedly turns to prism workpiece thus.
Clamp bottom board 2 is provided with counter sink 2-1, elasticity profiling jig body 1 is provided with screwed hole 1-3, described hold-down screw 3 is coordinated with the screwed hole 1-3 on elasticity profiling jig body 1 by the counter sink 2-1 on clamp bottom board 2, together with being installed in elasticity profiling jig body 1 by clamp bottom board 2, clamp bottom board 2 hold-down screw 3 is fixed on fine turning lathe index table.
Elasticity profiling jig body 1 is upper and lower two pawl designs, comprise dewclaw 1-1 and lower claw 1-2 corresponding thereto, dewclaw 1-1 is the workpiece locking mechanism adopting straight sheet spring flexible forms, the straight sheet spring of dewclaw 1-1 is provided with pinching screw 4, the gap between dewclaw 1-1 and lower claw 1-2 can be adjusted by adjustment pinching screw 4.
The end of dewclaw 1-1 is provided with Upper gasket 5, the end of lower claw 1-2 is provided with lower gasket 6, two gasket materials are aluminium, size is between gripper jaw section and turn between prism two non-operative end surface appearance and sizes, after turning to prism two non-operative end surface and two panels pad compression fit, interference embeds between elasticity profiling jig body dewclaw 1-1 and lower claw 1-2, after good workpiece to be calibrated and lathe index table rotating shaft relative position, recycling pinching screw 4 adjusts upper and lower two pawl 1-1,1-2 elastic gap and fixedly turns to prism workpiece.
As can be seen from the above embodiments, the utility model has following distinguishing feature:
(1) because the upper and lower two pawl clamping faces of elasticity profiling jig are vertical with fine turning lathe index table gyroaxis, fine turning lathe main shaft keeps vertical with index table gyroaxis simultaneously, and add man-hour diamond cutter and do in-movement with main shaft High Rotation Speed, the plane (namely turning to prism machined surface) that the track of point of a knife is formed just can ensure vertical with clamping face maintenance.
(2) hardness of CVD ZnSe polycrystalline material is little compared with other infrared optical material, Knoop hardness is only 105kg/mm2, process and fixture rigid contact, impression is very easily produced even cracked under local pressure effect, therefore elasticity profiling jig dewclaw is the workpiece locking mechanism adopting straight sheet spring flexible forms, can be finely tuned two pawl elastic gap sizes by pinching screw, play fixation workpiece, regulate the effect of clamp pressure.
(3) in processing feeding process, diamond cutter must remove the unnecessary size of each machined surface of workpiece, ensure not interfere with each other with elasticity profiling jig gripper jaw simultaneously, therefore prism two non-operative end surface appearance and sizes are turned to should to be greater than holder face size, contact area less at the same pressure can produce larger pressure, must have enough clamp pressures in addition to ensure that workpiece process relative movement does not occur.Therefore, for head it off introduces pad at fixture, gasket material is aluminium, and size is between gripper jaw section and turn between prism two non-operative end surface appearance and sizes, when actual holding workpiece, footprint pressure can be reduced while guarantee clamping stability and clamp precision.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and replacement, these improve and replace and also should be considered as protection domain of the present utility model.
