Description
Technical field
The utility model belongs to a kind of mechanical workout supplementary unit, is specifically related to a kind of camera lens turning clamp.
Background technology
In the design of infrared optical system, in order to the quantity of eyeglass in minimizing system, generally one or two surface design of eyeglass is become aspheric surface, for aspheric processing, grinding machine instrument just seems helpless.Generally adopt single-point numerical control diamond lathe to carry out to aspheric processing, add man-hour, generally clamped by infra-red material with fixture, adjustment is processed the heart with the main shaft of lathe.Therefore, the design of fixture is the part that can the face shape of eyeglass after processing reach the key of design requirements.
Utility model content
The purpose of this utility model is to provide a kind of camera lens turning clamp, carries out clamping add man-hour to eyeglass, and the face shape of the eyeglass after processing well can reach the requirement of design.
For achieving the above object, the technical scheme that an embodiment of the present utility model is taked is:
Comprise circular spring chuck seat and circular elastic card cap; Spring chuck seat comprises pedestal and clamping part, pedestal is provided with absorption bottom surface and to heart cylindrical surface, retaining part is in pedestal upper surface, comprise outside screw, cylindrical surface and outer conical surface successively from top to bottom, clamping part upper end is provided with elastic eyeglass clamping hole, pedestal and center, clamping part joint are provided with springhole, and clamping part upper end is provided with multiple elastic groove uniform vertically; Elastic card cap and spring chuck cover for seat connect, and elastic card cap bottom is provided with the internal thread and internal conical surface that coordinate with pedestal outside screw, and the tapering of internal conical surface is greater than the tapering of outer conical surface.
Preferably, the width of elastic groove is 1.5 millimeters, and quantity is 12 ~ 18.
Preferably, the cylindrical of pedestal is provided with hatching knurling.
The beneficial effect that this camera lens turning clamp produces is: coordinated by spring chuck seat and elastic card cap, elastic card cap is rotated down on spring chuck seat, the clamping part of spring chuck seat is impelled to tighten up, thus the circular eyeglass clamping that will be positioned on spring chuck seat, carry out the turnery processing of lens surface.

Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with the utility model specific embodiment and corresponding accompanying drawing, technical solutions of the utility model are clearly and completely described.
With reference to the structural representation of figure 1 ~ Fig. 4, Fig. 1 ~ Figure 4 shows that embodiment of a kind of camera lens turning clamp of the present utility model.In the present embodiment, camera lens turning clamp comprises circular spring chuck seat 100 and circular elastic card cap 200; Spring chuck seat 100 comprises pedestal 101 and clamping part 102, pedestal 101 is provided with absorption bottom surface 103 and to heart cylindrical surface 105, absorption bottom surface will reach higher surfaceness, ensure that fixture can well be adsorbed on the sucker of diamond lathe, to heart cylindrical surface for ensureing that the rotation center of fixture overlaps with the live spindle of diamond lathe; Clamping part 102 is positioned at pedestal 101 upper surface, comprise outside screw 105, cylindrical surface 107 and outer conical surface 108 from top to bottom successively, clamping part 102 upper end is provided with elastic eyeglass clamping hole 109, pedestal 101 and center, clamping part 102 joint are provided with springhole 110, and clamping part 102 upper end is provided with multiple elastic groove 111 uniform vertically; Elastic card cap 200 and spring chuck seat 100 are socketed, and elastic card cap 200 bottom is provided with the internal thread 201 and internal conical surface 202 that coordinate with pedestal outside screw, and the tapering of internal conical surface 202 is greater than the tapering of outer conical surface 108.Coordinated by spring chuck seat 100 and elastic card cap 200, elastic card cap 200 is rotated down on spring chuck seat 100, the clamping part 102 of spring chuck seat 100 is impelled to tighten up, thus the circular eyeglass clamping that will be positioned on spring chuck seat 100, carry out the turnery processing of lens surface.
With reference to figure 1 ~ Fig. 3, in an embodiment of the present utility model, the width of elastic groove 111 is 1.5 millimeters, and quantity is 12 ~ 18, can obtain a balance preferably at guarantee fixture by between eyeglass clamping and minimizing eyeglass recoverable deformation.
With reference to figure 1 ~ Fig. 3, in an embodiment of the present utility model, the cylindrical of pedestal 101 is provided with hatching knurling 104, facilitates the installation of fixture on sucker and takes off.
Above-mentioned embodiment is used for explaining and the utility model is described; instead of the utility model is limited; in the protection domain of spirit of the present utility model and claim, any amendment make the utility model and change, all fall into protection domain of the present utility model.
