(2) part is loaded in hole, location, to be processed of regulation part, makes to be processed of part to be completely superposed with inclined-plane A, Adjusting nut makes two pressing plates fit with the two ends of part respectively simultaneously, it is achieved part laterally-clamped；

(3) on drilling machine, first symmetrical holes I is processed by fixing drill bushing；

(4) when processing second hole II of symmetrical holes, unclamp nut, unload part, part head and the tail are exchanged and load simultaneously and determine In hole, position, then regulating to be processed of part, make to be processed of part to be completely superposed with inclined-plane B, adjusting nut makes simultaneously Fit in two pressing plates two ends with part respectively, it is achieved part laterally-clamped；

(5) on drilling machine, first symmetrical holes II is processed by fixing drill bushing；

(6) unclamp nut (5), unload part, now complete connecting shaft part symmetry angle hole hole I and the processing of hole II.

Advantages of the present invention: the present invention uses a kind of angle block gauge and hold down gag combination, simple and compact for structure, improves fixture Versatility, series parts key characteristic concordance, make the recycling rate of waterused of fixture improve, make the sleeve clamp can be for multiple processing Objects services, improves production efficiency, saves labor time；Improve precision, simple to operate, clamp conveniently, low cost of manufacture.
