Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
With reference to Fig. 1, Fig. 2, Fig. 3, a kind of hydraulically operated fixture boring crank axle end face hole for horizontal Machining centers, is arranged on horizontal Machining centers workbench.This fixture comprises: clamp system, connecting rod positioning mechanism.
Described clamp system comprises base 4, V-arrangement back-up block 5A, V-arrangement back-up block 5B, pressing plate 6, fastening nut 7, stud 8, described V-arrangement back-up block 5A is fixed on base leading portion, V-arrangement back-up block 5B is positioned at base rear end and can according to the length adjustment position of institute's machining crankshafts, for supporting trunnion 2A, 2B of bent axle respectively, described stud 8 is threaded connection and is arranged on V-arrangement back-up block 5A, 5B respectively, it is provided with pressing plate 6, and by fastening nut 7 clamping spindle neck 2A, 2B.
Described connecting rod positioning mechanism comprises locating piece 9A, locating piece 9B, slide plate 10, solenoid directional control valve 11, overflow valve 12, hydraulic pump 13, oil return box 14, described locating piece 9A is fixedly mounted on slide plate 10, locating piece 9B by hydraulic-driven can on slide plate 10 transverse shifting, described slide plate 10 is arranged on base 4 and also can adjusts according to the position in connecting rod footpath, described solenoid directional control valve 11, overflow valve 12, hydraulic pump 13, oil return box 14, forming hydraulic circuit provides power for removable location-plate 9B.
Use procedure of the present invention is: for bent axle shown in Fig. 1, this bent axle has 3 trunnions, 2 connecting rod footpaths, two ends all need processing, first main bearing journal 2A is placed on V-arrangement back-up block 5A when holding greatly by processing, then V-arrangement back-up block 5B supports main shaft neck 2B is adjusted, after placing bent axle, the position of adjustment slide plate 10 makes locating piece 9A contact with crankshaft-link rod footpath 3, now connect the switch of solenoid directional control valve 11 and to make it work in upper, locating piece 9B under the thrust of hydraulic pump 13 near 9A to realize connecting rod footpath 3 clamping and positioning, after reaching specified pressure, hydraulic pump is by overflow valve 12 off-load, solenoid directional control valve 11 works in meta simultaneously, keep stable clamping force, last resort pressing plate 6, fastening nut 7, stud 8 compresses main bearing journal, prevent bent axle stressed play in process engineering.When processing one end, numerical control table, NC table revolves turnback, and the processing other end, after all processing, first unclamp front and back pressing plate, then solenoid directional control valve 11 works in bottom, makes locating piece 9B unclamp rod journal 3, finally unloads part.
