Description
Technical field
The utility model relates to optical processing technology field, particularly a kind of sphere processing novel compositions frock.
Background technology
Germanium crystal is optical material conventional in infrared optical system, the main lens be used as in optical imaging system.Along with the fast development of science and technology, the lens type that imaging system needs and specification get more and more, the processing tool model comparision that adopts of our finishing lenses is single at present, and usual a kind of frock can only be used for a kind of processing of specification pherical product, can not realize multi-product and use.The tool positioning surface used due to fine finishining pherical product is that on-line machining forms, and guarantees positioning precision, and workpiece is utilize vacuum adsorption force to reach the object of clamping on locating surface.When processing work, existing frock is applicable to first process concave surface, reprocessing convex surface, this processing technology is difficult to the precision simultaneously accurately ensureing workpiece gross thickness and center thickness, existing tool structure immobilizes simultaneously, can not adjust up and down, after causing the convex surface of processing work, cannot concave surface be reprocessed, can not realize recycling, add frock cost.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of sphere processing novel compositions frock, and it can improve the quality of products, and reduces frock cost, improves infrared crystal pherical product qualification rate.
For achieving the above object, the utility model takes following technical scheme:
Novel compositions frock is used in a kind of sphere processing, and it comprises mold, bed die and locating piece;
This mold is cylindrical shape, has large footpath section and path section; The internal diameter of this large footpath section is greater than the internal diameter of this path section; This path section inwall is provided with internal thread;
This bed die has annular projection portion and makes cross section be cross, and this lug boss periphery is provided with the external screw thread corresponding with this internal thread; This bed die and this mold are threaded connection; This bed die top is plane, and inside is provided with through duct of bleeding;
This locating piece is ring-type, has the internal thread corresponding with this external screw thread; This locating piece and this bed die are threaded connection and are positioned at this mold lower end.
Further, described bed die lower end has the external screw thread for being connected with lathe.
Preferably, described mold, bed die and locating piece are nylon or bakelite material.
The beneficial effects of the utility model are: the utility model sphere processing novel compositions frock, can improve the quality of products, and reduce frock cost, improve infrared crystal pherical product qualification rate.
Accompanying drawing explanation
Fig. 1 is the mold schematic diagram of the utility model frock.
Fig. 2 is the bed die schematic diagram of the utility model frock.
Fig. 3 is the locating piece schematic diagram of the utility model frock.
Fig. 4 is the assembling schematic diagram of the utility model frock.
Detailed description of the invention
Below by illustrate by reference to the accompanying drawings with specific embodiment structure of the present utility model and the technique effect for reaching, but selected embodiment is only for illustration of explanation, and is not used to limit scope of the present utility model.
As Figure 1-4, the utility model provides a kind of sphere processing novel compositions frock, and it comprises mold 1, bed die 2 and locating piece 3.This mold 1, bed die 2 and locating piece 3 can be the flexible material such as nylon or bakelite.
As shown in Figure 1, this mold 1 is cylindrical shape, has large footpath section 11 and path section 12.This section 11 inside, large footpath is used for place work piece, and its internal diameter is greater than the internal diameter of this path section 12.This path section 12 inwall is provided with internal thread, for connecting this bed die 2.
As shown in Figure 2, Figure 4 shows, this bed die 2 has annular projection portion 21 and makes cross section be cross, and this lug boss 21 periphery is provided with the external screw thread corresponding with this internal thread.This bed die 2 is threaded connection with this mold 1.Upper and lower mould is threaded connection and thus stably can adjusts height up and down.This bed die 2 top is plane, and inside is provided with through duct 22 of bleeding.For the ease of being connected with lathe, this bed die 2 lower end has external screw thread.
As shown in Figure 3, Figure 4, this locating piece 3 is ring-type, has the internal thread corresponding with this external screw thread.This locating piece 3 is threaded connection with this bed die 2 and is positioned at this mold 1 lower end.When the distance of upper and lower mould is adjusted, the relative position of mold 1 and bed die 2 can be fixed by locating piece 3.
The utility model frock is when processing infra-red material sphere and other materials need process sphere, as shown in Figure 4, workpiece 4 is placed on bed die 2 top planes, namely on reference platform, with this plane and this mold 1 large footpath section 11 inwall for benchmark, negative-pressure adsorption is taken out and clamping work pieces 4 by the duct 22 of bleeding of bed die 2, then according to workpiece 4 variable thickness sample, be threaded by adjustment mold 1 and adjust height, when the distance of upper and lower mould is adjusted, by rotating locating piece 3 make it be close to relative position that this mold 1 can fix mold 1 and bed die 2.
To sum up, advantage of the present utility model is as follows:
The utility model is when processing infra-red material sphere and other materials need process sphere, horizontal base plan can not need to repeat processing, mold can adjust axial location height up and down by screw thread, when ensureing first to process convex surface, concave surface has sufficiently high positioning reference plane, thus in high volume production process can concave surface and convex surface can reprocessabilty, and can the total thickness size of qualified control workpiece, also can meet the manufacturing requirements of low cost while improve product percent of pass.
The utility model limits with described claim.But based on this, those of ordinary skill in the art can make all obvious changes or change, all should within main spirits of the present utility model and protection domain.
