Described positioning seat is connected with pillar through bolt.
Described pillar is connected with base plate through alignment pin, the pin-and-hole of described alignment pin and pillar and the pin-and-hole interference fit of base plate.
Compared with prior art, the utility model has following beneficial effect:
Of the present utility model for the mach efficient positioning fixture of engine aluminum die casting, comprise base plate, described base plate is provided with two pillars, two described pillars are on the diagonal of base plate, the top of described pillar is connected with positioning seat, and described positioning seat offers through hole, is equipped with resilient key in described through hole, positioning seat is stretched out in the upper end of described resilient key, and the lower end of described resilient key is provided with return spring.The error of the casting hole pitch-row of aluminium diecasting own can be eliminated and offset by resilient key, directly aluminium diecasting is set on the resilient key of two diagonal positions settings, ensure that the uniformity of machinofacture; Also improve the efficiency of the installation of foundry goods.
The utility model is owing to can directly position the aluminium diecasting that pitch-row changes simultaneously, even if that is to say that aluminium diecasting itself exists error, can position efficiently equally, thus reduce the making precision of aluminium diecasting, reduce production cost.
