Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail, but the utility model is not limited to these embodiments.
Embodiment one: this embodiment, part to be processed to need processing eight holes, elaborates to the utility model.
As shown in Figure 5, a kind of assembled tool for machining large part high position precision holes group, comprises boring jig tooling 1, with the matching used power boring bar 9 of boring jig tooling 1 and for driving the boring machine 10 of power boring bar 9:
As shown in Figure 1 and Figure 2, boring jig tooling 1 comprises for being arranged on the assembling base plane on part 7 to be processed and the boring bar datum level for correcting power boring bar 9, the appearance and size of described boring jig tooling 1 sets according to the distribution situation of hole group on part 7 to be processed, is as the criterion with the hole group that can cover on part 7 to be processed; Described boring jig tooling 1 offers control wells group, control wells group comprises eight control wells 2, the distribution situation of these eight control wells 2 is identical with the distribution situation in eight holes of hole group on composition part 7 to be processed, and the hole end surface 1 of each control wells 2 need be parallel to each other with hole end surface 26, the precision of each control wells 2 is not less than precision part 7 to be processed forming each hole of hole group, and the hole end surface of each control wells 2 need meet hole on part 7 to be processed to the requirement of flatness; The central authorities of described boring jig tooling 1 offer endoporus, the inwall of endoporus are provided with four for calibrating the jacking block 4 of the installation site of boring jig tooling 1 on part 7 to be processed; In addition, described boring jig tooling 1 has accurately portrayed central cross line 1.
It should be noted that, the outline of boring jig tooling 1 is not limited only to the octagon shown in Fig. 1, and it can also be the geometry such as circle, ellipse, triangle, as long as boring jig tooling 1 can cover the hole group of part to be processed.
