Description
Technical field
The utility model relates to metal cutting process fixture, especially a kind of part processing clamp locating stud of efficient, high-precision real.
Background technique
Locating stud is a kind of positioning element conventional on fixture in machining, and the usual location to a part generally adopts plane and two pits to locate now, and on part, utilize screw rod and pressing plate to apply certain clamping force.Compression strength often due to operator is excessive, cause workpiece adding man-hour distortion, show in the fine finishing for cylinder body, the larger part of thin wall by for give prominence to.In order to ensure the machining accuracy of part, the selection compressing point is wanted quite most.But have now numerous parts to be airflow design, be difficult to find suitable compression point, even and if have suitable compression point, but the compression feel of each operator is different also can affect processing precision of products.
According to retrieval, domestic not yet have the patent application identical with the utility model.
Summary of the invention
The purpose of this utility model is to provide one not to be needed repeatedly to adjust setscrew nut, easy to use, positioning precision is high, with steering wheel automatic spacing controlling mechanism.
The technological scheme that the utility model adopts is:
A kind of fixture Automatic-clamping locating stud, is made up of setting sleeve, piston, location key seat, tighting rod, stage clip and sealing steel pad; Wherein setting sleeve is connected with location key seat interference, and piston is threaded with tighting rod, described piston and tighting rod is respectively equipped with oil sealing and moves left and right at location key seat; Be equipped with between the inner chamber of setting sleeve and location key seat and seal steel pad, sealing steel pad and location key seat form a sealed chamber, and piston is sealed chamber's separately left and right chamber; Stage clip is encapsulated in left chamber; Setting sleeve is provided with and the aperture that adapts on chuck body vent, is provided with circular groove in the middle of setting sleeve and location key seat, and described circular groove is communicated with aperture and right chamber.
Further, the oil sealing of piston and tighting rod is positioned at their centre.
The beneficial effects of the utility model are:
1. the utility model drives piston and the left and right motion of tighting rod by the elastic force of spring through air pressure adjustment, solves the scarce filling originally needing repeatedly to adjust setscrew nut;
2. the utility model solves part yielding deficiency in compaction process, improves quality of product;
3. its compact structure of the utility model is easy to use, meets the needs of typical products in mass production machining high-precision;
4. the utility model it have clamping automation function, improve working efficiency, reduce labor intensity.

Embodiment
Be further described below in conjunction with accompanying drawing mark:
In the present invention, the noun of locality such as " upper and lower, left and right " of use typically refers to reference to upper and lower, left and right shown in the drawings; " inside and outside " refers to profile inside and outside relative to each parts itself.
1-6 setting sleeve 2, piston 3, location key seat 4, tighting rod 5, stage clip 8 and sealing steel pad 9 form by reference to the accompanying drawings.Wherein setting sleeve 2 and location key seat 4 adopt rigidity interference to be connected, and stage clip 8 are encapsulated in the cavity of resorption of piston 3 simultaneously.Piston 3 adopts with tighting rod 5 and is threaded, and piston 3 is equipped with seal oil envelope 7, tighting rod 5 is equipped with seal oil envelope 6.Be equipped with between the endoporus of setting sleeve 2 and location key seat 4 and seal steel pad 9; Sealing steel pad 9, location key seat 4 and tighting rod 5 form a cavity, piston 3 is divided into left and right two chambers cavity, wherein stage clip 8 is encapsulated in left chamber, right chamber 10 and setting sleeve 2 communicate with the circular groove in the middle of location key seat 4, and setting sleeve 2 is connected with chuck body 1 air distribution hole (shown in Fig. 1 arrow).
Above-mentioned assembling parts becomes one can after self-holding locating stud.In chuck body 1 required for being loaded, the workpiece will processed again loads on clamp locating pin, open external high pressure air-break switch, first high-pressure air can enter the hole of setting sleeve 2 by the air distribution hole (shown in Fig. 1 arrow) in chuck body 1, enter the circular groove that setting sleeve 2 is middle with location key seat 4 again, finally enter the right chamber 10 of piston 3.At this moment piston 3 drives tighting rod 5 to left lateral, and four conical surfaces that the taper of tighting rod 5 right-hand member part is pressed on location key seat 4 right-hand part make its spreading, thus the workpiece pin-and-hole clamping that will be contained on locating stud.After work pieces process completes, close external high pressure air-break switch, by the effect of stage clip 8, piston 3 drives tighting rod to right lateral, the spring collet resilience on location key seat 4, and workpiece unclamps, and so just constitutes a kind of fixture Automatic-clamping locating stud.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, said structure all should be considered as belonging to protection domain of the present utility model.
