Abstract

The utility model discloses a clamp for machining of the spherical surface of a butterfly valve. The clamp comprises a chuck and positioning-pin soft jaws which are connected to the chuck through T-shaped blocks, a round protrusion is arranged on the end face of one end, making contact with the butterfly valve, of each positioning-pin soft jaw, and the round protrusions are matched with a positioning hole of the butterfly valve. The butterfly valve is tightly clamped through the positioning-pin soft jaws, and therefore the butterfly valve is accurately positioned.

Description

A kind of fixture of processing butterfly valve spherical surface

Technical field

The utility model relates to a kind of fixture, particularly a kind of fixture of processing butterfly valve spherical surface.

Background technology

At present, when processing butterfly valve spherical surface, conventionally use the soft pawl of alignment pin being fixed on oild chuck to position butterfly valve, because the soft pawl of this alignment pin is the bulk of a cuboid, when butterfly valve is positioned, rely on the soft pawl of alignment pin of manual operation both sides to clamp it, therefore can not accurately locate butterfly valve locating hole, the error of generation is larger, thereby cause being difficult for meeting the requirement of product high precision position when the spherical surface of processing butterfly valve, and at the bottom of efficiency.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of for processing the fixture of butterfly valve spherical surface, this fixture is designed into special location structure on standard claw, by oild chuck high accuracy Self-centering Action, realize butterfly valve is accurately located, improve working (machining) efficiency.

For achieving the above object, the utility model provides following technical scheme: a kind of fixture of processing butterfly valve spherical surface, comprise the soft pawl of oild chuck and alignment pin, the soft pawl of alignment pin is connected with oild chuck by T-shaped, the soft pawl of alignment pin arranges circular protrusions at one end end face of contact butterfly valve, and circular protrusions coordinates with the locating hole of butterfly valve.

Preferably, the bottom surface of the soft pawl of alignment pin arranges full-height tooth, and full-height tooth is consistent with T-shaped full-height tooth.

Adopt above technical scheme, a kind of fixture of processing butterfly valve spherical surface, comprise the soft pawl of oild chuck and alignment pin, the soft pawl of alignment pin is connected with oild chuck by T-shaped, and the soft pawl of alignment pin arranges circular protrusions at one end end face of contact butterfly valve, and circular protrusions coordinates with the locating hole of butterfly valve, round bump puts in butterfly valve locating hole just, the slip in the vertical direction of restriction butterfly valve, the butterfly valve both sides soft pawl of alignment pin clamps butterfly valve, thereby butterfly valve is accurately located.

The bottom surface of the soft pawl of alignment pin arranges full-height tooth, full-height tooth is consistent with T-shaped full-height tooth, the soft pawl of alignment pin can not slide with respect to T-shaped in the horizontal direction, and T-shaped by being fixed on after oild chuck hydraulic compression in the T groove of oild chuck, thereby guaranteed the stable of crudy, easy to operate, improved the working (machining) efficiency of butterfly valve.

The specific embodiment

Below in conjunction with accompanying drawing, the description by embodiment, is described further the utility model:

The utility model is for processing the fixture of butterfly valve spherical surface, as shown in Figure 1, comprise the soft pawl 2 of oild chuck 1 and alignment pin, as Fig. 2, shown in Fig. 3, the soft pawl 1 of alignment pin is connected with T shape piece 3 screws by screw 7, T shape piece 3 is fixed in the T-slot of side of oild chuck 1, the soft pawl 2 of alignment pin arranges full-height tooth 6 as shown in Figure 5 on the surface contacting with T shape piece 3, this full-height tooth 6 coordinates with T-shaped full-height tooth 8, make the soft pawl 2 of alignment pin be difficult for sliding with respect to T-shaped 3, after the hydraulic self-centering of oild chuck 1, be fixed on for T-shaped 8 in the T groove of oild chuck 1, thereby defining the soft pawl 2 of alignment pin can not slide in the horizontal direction, as shown in Figure 4, the soft pawl 2 of alignment pin arranges circular protrusions 5 at contact butterfly valve locating hole 9 end faces, this circular protrusions 5 coordinates with the locating hole 9 of butterfly valve, circular protrusions 5 puts in butterfly valve locating hole 9 as shown in Figure 6 just, the slip in the vertical direction of restriction butterfly valve 4, thereby butterfly valve 4 is accurately located.

After processing for the first time butterfly valve 4 spherical surfaces, at T-shaped 3 places, write down the position of the soft pawl 2 of alignment pin, later each when processing the butterfly valve 4 of same model, all the soft pawl 2 of alignment pin is contained in to the same position of T-shaped.

Above-described is only preferred embodiment of the present utility model; it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
