Abstract
The utility model discloses a centralizing and edging clamp of small diameter glasses, which comprises a clamp. The clamp is provided with a central hole. The wall of the clamp is provided with an air vent communicated with the central hole. The utility model is reasonable in structure, and can lower air resistance to glasses through the air vent, making air of lamps flow from the air vent. Therefore, the utility model has the advantages of convenient installation, high processing quality, and good processing effect.
Description
Technical field:
The utility model relates to a kind of eyeglass machining tool.
Background technology:
The centring edging of optical mirror slip is one of basic craft course of optical element manufacturing.The centering edging of lens makes its optical axis (two spheric curvature center on lines) and face of cylinder geometrical axis coincide exactly, simultaneously cylindrical is ground to given size.When lens exist the center inclined to one side, the coaxiality of optical system will be destroyed, and cause coma, aberration etc., thereby reduce picture element.So, polish later lens and all should carry out centring edging, make the coincidence degree of optical axis reach the regulation requirement.
At present, the method of domestic and international centring edging, mostly adopt the mechanical centering method, utilize the radial component (centering power) of two joint clamping forces, lens are moved to the one side that does not contact with joint, with till joint contacts, the centre of sphere on two surfaces of lens is positioned on the axial line of joint, reaches the purpose of centering until whole surface.Existing brass anchor clamps, after eyeglass clamped, port surface easily produced distortion, made the center of lens skew, and clamp head easily produces bending, causes the eyeglass that grinds to be ellipse or taper.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the centring edging anchor clamps of the minor diameter eyeglass that processing effect is good.
Technical solution of the present utility model is:
A kind of centring edging anchor clamps of minor diameter eyeglass comprise clamp body, and clamp body is provided with centre bore, it is characterized in that: be provided with the passage that communicates with centre bore on the body wall of clamp body.
The utility model is rational in infrastructure, the passage that is provided with on the anchor clamps body wall, and the resistance in the time of can reducing air to the clamping eyeglass allows the air of anchor clamps loyalty flow out from the hole, and both convenient the installation guarantees crudy again, and processing effect is good.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing is the configuration diagram of an embodiment of the utility model.
The specific embodiment:
A kind of centring edging anchor clamps of minor diameter eyeglass comprise steel clamp body 1, and clamp body 1 is provided with centre bore 2, are provided with the passage 3 that communicates with centre bore 2 on the body wall of clamp body.Also have eyeglass 4, beveler 5 among the figure.
