Abstract
The utility model discloses a chuck for machining a jewelry, which comprises a hollow cylindrical clamping body (1). The lower part of the clamping body is a connecting part, the upper part of the clamping body is a clamping part and the middle part of the clamping body is provided with a transverse through hole (2); the connecting part is provided with internal screw threads (5) in threaded connection with an external machining table; and the clamping part is a claw (6) of which four pedals are collected inwards for clamping the jewelry. Compared with the prior art, the chuck for machining the jewelry has the advantages of simple structure and low cost, is convenient and quick in operation and is reliable in clamping.
Description
Technical field
The utility model relates to anchor clamps, relates in particular to a kind of chuck that is used for jewelry processing.
Background technology
The holder of diamond, diamond edge and other jewelry surface are carved with a plurality of facets, need they be clipped with special anchor clamps man-hour in that they are added.But there is complex operation in existing anchor clamps, the defective of clamping shakiness.
The utility model content
The utility model is the problems referred to above that will solve prior art, proposes a kind of chuck that is used for jewelry processing.
For solving the problems of the technologies described above, the technical scheme that the utility model proposes is a kind of chuck that is used for jewelry processing of design, the cylindric clamp with hollow, and this clamp bottom is a connecting portion, top is the hole that clamping part, middle part are provided with lateral direction penetrating; Described connecting portion is provided with the internal thread that is spirally connected with the external process platform; Described clamping part is the pawl in order to the clamping jewelry that pintongs inwardly draws in.
Described pintongs pawl forms the columned pit that caves inward at its top.
The outer surface of described clamping part is provided with an annular groove.
Compared with prior art, the utlity model has simple in structure, with low cost, easy to operate rapidly, the reliable advantage of clamping.
Description of drawings
Below in conjunction with drawings and Examples the utility model is made detailed explanation, wherein:
Fig. 1 is the stereo appearance figure of the utility model preferred embodiment;
Fig. 2 is the cutaway view of the utility model preferred embodiment;
Fig. 3 is the partial sectional view of the utility model preferred embodiment clamping diamond.
The specific embodiment
The utility model discloses a kind of chuck that is used for jewelry processing, referring to Fig. 1, it has the cylindric clamp 1 of hollow, and this clamp bottom is a connecting portion, and top is the hole 2 that clamping part, middle part are provided with lateral direction penetrating; Described connecting portion is provided with the internal thread 5 that is spirally connected with the external process platform; Described clamping part is the pawl 6 in order to the clamping jewelry that pintongs inwardly draws in.
Referring to the preferred embodiment shown in Fig. 2, the pintongs pawl forms the columned pit 3 that caves inward at its top.The outer surface of clamping part is provided with an annular groove 4.
The pintongs pawl is directly to open 4 road grooves in cylindric clamp 1 direct-axis direction to form the pintongs pawl, and the pit 3 that the pintongs pawl forms at its top is in order to the clamping jewelry.Here said jewelry can be diamond, jewel or the like, also can be the holder of diamond edge, and existing is that example is illustrated with the holder of clamping diamond edge.The diameter of pit 3 is slightly less than the diameter of diamond edge holder 7, the extension spring of an annular of placement in the annular groove 4 of the outer surface of clamping part.During use, ear of maize with a circle inserts in the hole 2 at clamp 1 middle part earlier, rotate ear of maize (effect of ear of maize is exactly the rotary arm that extends) then and clamp 1 is screwed on the machine table, have a thimble that can stretch to place in the cavity of clamp 1 on the machine table by internal thread 5.When thimble moves up, the pintongs pawl can be backed down slightly, so that take out or put into diamond edge holder 7; When thimble moved down, the pintongs pawl clamped diamond edge holder 7 under the effect of self elasticity and tension spring tension.Extension spring also has an effect to be: move on thimble when the pintongs pawl backed down and apply pulling force, follow the string to prevent pintongs pawl overextended mouth opening.
Above embodiment is only for illustrating non-providing constraints.Anyly do not break away from spirit of the present invention and category, and, all should be contained among the application's the claim scope its equivalent modifications of carrying out or change.
Claims (3)
