Description
Technical field
The utility model is about a kind of blank processing swelling anchor clamps, is meant that especially a kind of adaptability is strong and to the firm blank processing swelling anchor clamps in blank location.
Background technology
At present, add man-hour, generally at first need blank to be positioned, carry out corresponding manufacturing procedure afterwards again, obviously locate whether firmly, then directly have influence on the machining accuracy of workpiece by the locating hole of blank for blank.For example for the blank of magnadure, because magnadure is more active, the casting more complicated, mostly again is thin-walled parts, the locating hole distortion is serious, so in the processing use, be according to the locating hole full-size(d) of different blanks, and then manufacturing alignment pin, the mode adaptability of obvious this employing alignment pin is not good.
The utility model content
At foregoing, the purpose of this utility model promptly is to provide a kind of adaptability to process the swelling anchor clamps by force and to the firm blank in blank location.
The purpose of this utility model is achieved through the following technical solutions:
The utility model provides a kind of blank processing swelling anchor clamps, be provided with fixed head and supporting pin, wherein an end of this supporting pin is fixed on this fixed head, especially the sheathed swelling cover that can match with the hole on the blank that is fixed with on all sides of nearly this supporting pin other end.
On the above-mentioned basis, wherein:
Top at this supporting pin other end also is fixed with the holddown plate that is used for compressing blank by lock-screw.
Also be fixed with alignment pin on the described fixed head.
On this basis, wherein further:
Described swelling is arranged with expansion set, but the two ends up and down of this expansion set be respectively arranged with successively stretching stretch in this expansion set on conical surface distensible ring with and should on the relative following conical surface distensible ring of conical surface distensible ring, be formed with on the internal face of described expansion set successively respectively with described on, the last conical surface that the conical surface of following conical surface distensible ring matches and the following conical surface, wherein on this, be provided with supporting screw and housing screw between conical surface distensible ring and the following conical surface distensible ring, wherein housing screw passes on this conical surface distensible ring and then penetrates down conical surface distensible ring and form threaded engagement with following conical surface distensible ring, and supporting screw is to form threaded engagement with last conical surface distensible ring and pass conical surface distensible ring and then only replace and descending on the conical surface distensible ring.Wherein, in this expansion set, also be arranged with the guide pin bushing that can be set on the described supporting pin, be formed with the last conical surface and the following conical surface that match with the conical surface of described upper and lower conical surface distensible ring respectively successively on the outside wall surface of described guide pin bushing.
Be formed with flange on the described supporting pin, be formed with screw on the following conical surface distensible ring of swelling cover, this swelling cover is to pass this flange by housing screw to lock with the screw on the following conical surface distensible ring and cooperate, and then swelling is sheathed and be fixed on this supporting pin.
The utility model is compared to prior art, and its advantage is, the utility model is simple in structure, it is easy to maintenance to install and use, the location is firm, durability is high, with low cost, and the new method of hi-Fix is provided in the fine finishining of cast blank.Since the utility model be by the swelling cover to blank swelling fix, therefore can change the size of adjusting the swelling cover according to the blank internal diameter size, particularly to highly higher blank, by having carried out swelling high-end, increased and clamped back vertical direction intensity, therefore overcome original structure and can not adapt to blank and change and the different clamping forces of needs, improved that work in-process produces the processing dimension instability that vibrations cause because support on the low side, processing for subsequent fine provides guarantee.In addition, at the height difference of the blank of different product, the supporting pin that can change differing heights with, therefore, the utility model applicability is strong.
