Detailed description of the invention
As Fig. 1, 2, shown in 3, the utility model comprises substrate 1, upper cover plate 2 and one group of main pump housing positional stations, substrate 1 is respectively equipped with Installing machine tool hole, one group of withstanding tight block passing hole and one group of connecting rod passing hole, upper cover plate 2 is respectively equipped with pressure strip passing hole and one group of drill bit passing hole on one group, upper cover plate 2 by one group of erection column fixed installation on substrate 1, main pump housing positional stations comprises and holds out against cylinder 3, withstanding tight block 4, pressure strip 5, a pair back-moving spring 6, a pair compression cylinder 7 and a pair air cylinder pressure plate 8, hold out against cylinder 3 is arranged on substrate 1 bottom by mount pad, and hold out against the piston rod of cylinder 3 through withstanding tight block passing hole, withstanding tight block 4 is provided with V-type groove, withstanding tight block 4 be arranged on hold out against cylinder 3 piston rod on, the two ends of pressure strip 5 are respectively equipped with boss 5-1, the two ends of a pair back-moving spring 6 are connected between upper cover plate 2 and pressure strip 5, a pair compression cylinder 7 is installed on substrate 1 by mount pad, a pair air cylinder pressure plate 8 is arranged on the piston rod of a pair compression cylinder 7 respectively, and a pair air cylinder pressure plate 8 is pressed on the boss 5-1 at the two ends of pressure strip 5 respectively.
Also has auxiliary pick-off unit, auxiliary pick-off unit comprises handle and connecting rod 9 and kinematic link 10, handle and connecting rod 9 is movably arranged on substrate 1 by bearing pin, and kinematic link 10 is through connecting rod passing hole on substrate 1, and the two ends of kinematic link 10 are movably connected on handle and connecting rod 9 and pressure strip 5 respectively.
Working method and principle: first the utility model frock is mounted by means of bolts on the work top of lathe, then motorcycle main pump case 11 is placed on the V-type groove of withstanding tight block 4 of any main pump housing positional stations; Operation one: the piston rod that control device controls to hold out against cylinder 3 ejects, by motorcycle main pump case 11 jack-up, the upper surface of motorcycle main pump case 11 is against on pressure strip 5, and now the drill bit of lathe processes oil sump screw hole and rearview mirror hole respectively through drill bit passing hole; Operation two: after processing operation one, the piston rod that control device controls to hold out against cylinder 3 is retracted, withstanding tight block 4 is retracted, the piston rod that control device controls a pair compression cylinder 7 is retracted, and driving a pair air cylinder pressure plate 8 belling platform 5-1 downwards, driving pressure strip 5 to pressing down, now positioning datum changes, with the lower surface of motorcycle main pump case 11 for datum level, now the drill bit of lathe is lower from the side bores, and processes oilhole.After operation two processes, manual depression handle and connecting rod 9, lifts pressure strip 5 by kinematic link 10, conveniently takes out the part processed.
