Abstract

The utility model discloses a novel fixture for triangular prisms. The novel fixture comprises a fixture main body, a plurality of V-shaped grooves are arranged on an end surface of the fixture main body, a plurality of outwards extending flanges are disposed on walls of two ends of each V-shaped groove and correspond to two ends of the corresponding triangular prism. During machining, the two ends of each triangular prism are respectively disposed on the corresponding flanges, and all surfaces of each triangular prism are prevented from contacting with the wall of the corresponding V-shaped groove, so that the walls of the V-shaped grooves cannot damage mirror surfaces of the triangular prisms; each triangular prism can be directly turned over after one surface of the triangular prism is machined so that the next surface of the triangular prism can be machined; and an integral rough machining procedure and an integral finish machining procedure can be completed on the fixture, and an integral machining procedure for each triangular prism can be completed after two ends, which contact with the corresponding flange, of the triangular prism are cut off. As the integral machining procedure is carried out on the same fixture, fixture replacement is not required, unnecessary machining processes are reduced, working time is saved, and production efficiency is improved.

Description

A kind of novel prism anchor clamps

Technical field

The utility model relates to a kind of anchor clamps, particularly a kind of novel prism anchor clamps.

Background technology

Traditional prism adds man-hour, and mostly the anchor clamps that adopted are the V-type groove, and prism directly places in the V-type groove and fixes; Like this wherein 2 end faces of prism contact with the cell wall of V-type groove, and 2 end face damages that cause prism to contact with the cell wall of V-type groove easily are particularly when fine finishining; Trickle damage can cause the mirror effect of prism not reach standard, in the time of can only be as roughing, and need select anchor clamps in addition for use during fine finishining; Be that the whole machining process process need is changed anchor clamps or a plurality of processing technology combines; The whole machining process process is very complicated, and expends man-hour, and production efficiency is not high.

Summary of the invention

In order to overcome the deficiency of prior art, the utility model provides a kind of novel prism anchor clamps, and these anchor clamps can be applied to the whole machining process process of prism, need not to change anchor clamps, and production efficiency is high.

The utility model solves the technical scheme that its technical problem adopted:

A kind of novel prism anchor clamps; It is characterized in that comprising jig main body; Offer several V-type grooves on the said jig main body end face, the cell wall at said V-type groove two ends is provided with some overhanging flanges, corresponding with the prism two ends respectively configuration of said flange; And when the two ends of prism placed on the flange respectively, arbitrary on prism did not all contact with V-type groove cell wall.

Said V-type groove is provided with 12, and the flange that is arranged on each V-type groove cell wall has 12, and each V-type groove comprises an inclination cell wall and vertical cell wall, and eight flanges wherein are arranged on the said inclination cell wall, and four flanges are arranged on the said vertical cell wall.

The bottom of said V-type groove also offers a groove.

The beneficial effect of the utility model is: the cell wall at the V-type groove two ends of jig main body is respectively arranged with flange; Corresponding with the prism two ends respectively configuration of flange adds man-hour, and the two ends of prism place on the flange respectively; Arbitrary on prism does not all contact with V-type groove cell wall; So the cell wall of V-type groove can be to the minute surface damage of prism, do not process one side directly the upset prism can process down simultaneously, and whole roughing and fine finishining process can be accomplished on these anchor clamps; After processing, to prism contact with flange two tip cut-offs can accomplish the whole machining process process of prism.Because the whole machining process process is all carried out on same anchor clamps, need not to change anchor clamps, reduces unnecessary processing technology, save man-hour, improve the efficient of producing.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified:

Fig. 1 is the utility model overall structure sketch map;

Fig. 2 is the local structure for amplifying sketch map of the utility model V-type groove;

Structural representation when Fig. 3 is the utility model application.

The specific embodiment

Referring to figs. 1 through Fig. 3, Fig. 1 to Fig. 3 is the structural representation of a specific embodiment of the utility model, and is as shown in the figure; A kind of novel prism anchor clamps; Comprise jig main body 1, offer 12 V-type grooves 11 on jig main body 1 end face, each V-type groove 11 can axially be placed two prisms 2; And each V-type groove 11 comprises an inclination cell wall 13 and vertical cell wall 14; The flange 12 that is arranged on each V-type groove 11 cell wall has 12, and wherein eight flanges 12 are arranged on the inclination cell wall 13, and is corresponding with four angles of prism 2 minute surfaces respectively; Four flanges 12 are arranged on the vertical cell wall 14, and are corresponding with centre position, prism 2 minute surface two ends respectively, add man-hour; The two ends of prism 2 place respectively on the flange 12; 2 arbitrary on prism does not all contact with V-type groove 11 cell walls, so the cell wall of V-type groove 11 can be to the damage of the minute surface of prism 2, and the minute surface that grinding tool grinding prism 2 is outside; Process the direct upset of one side prism 2 and can process down one side; And whole roughing and fine finishining process can accomplish on these anchor clamps, and after processing, two tip cut-offs that prism 2 is contacted with flange 12 can be accomplished the whole machining process process of prism 2.Because the whole machining process process is all carried out on same anchor clamps, need not to change anchor clamps, reduces unnecessary processing technology, save man-hour, improve the efficient of producing.

Further, the bottom of V-type groove 11 also offers a groove 15, and in the time of can preventing that prism 2 from putting into V-type groove 11, the wedge angle of prism 2 and cell wall collision and produce breakage and scrap improves the qualification rate of product.

More than the preferable enforcement of the utility model is specified; Certainly; The utility model can also adopt the form different with above-mentioned embodiment; For example change can be made according to prism to be processed 2 and process equipment in the shape of V-type groove 11, quantity, position on the jig main body 1, is not described further at this.

So those of ordinary skill in the art should belong in the protection domain of the utility model conversion of under the prerequisite of spirit of the present invention, being done that is equal to or corresponding the change.
