The specific embodiment
Below in conjunction with accompanying drawing, by embodiment the present invention is further described.
Embodiment:
Referring to Fig. 1 and Fig. 4, the rotary-tray with indexing lock mechanism comprises round tray 3 and base plate 2, and the center of circle of round tray 3 is installed on the base plate 2 by axle and bearing, and can 360 degree rotations.Be laid with four locating slots on the circumference of round tray 3, locating slot is deep-slotted chip breaker.On the base plate 2 in round tray 3 outsides indexing lock mechanism 1 is installed.By Fig. 2 and Fig. 3 as seen, indexing lock mechanism 1 comprises slide 9, push rod 7, bearing 14 and handle 12.
Referring to Fig. 7 and Fig. 8, slide 9 is tubulose, and an end is stepped hole, and the other end is through hole, and slide 9 is fixed on the base plate corresponding with the circumference of round tray 32 with plural bolt 11 by straight pin 10.Referring to Fig. 5 and Fig. 6, push rod 7 is step bars, one section is enlarged diameter section, another section is reduced diameter section, and is positioned at slide 9, and the end of the reduced diameter section of push rod 7 extends outside the stepped hole of slide 9, be set with compression spring 8 on the reduced diameter section of push rod 7, the end of enlarged diameter section is provided with groove, by bearing pin 6 and axle sleeve 5 roller 4 is installed in the groove, the locating slot corresponding matching on roller 4 and round tray 3 circumference.
Referring to Figure 12 and Figure 13, bearing 14 is upright tubulose, and the pore of bearing is stepped hole, epimere is enlarged diameter section, hypomere is reduced diameter section, and bearing 14 hypomeres one side corresponding with push rod 7 offers jogger hole, and the bottom of bearing 14 is fixed on the base plate by cover plate 16 and sunk screw 17.Referring to Fig. 9, Figure 10 and Figure 11, handle 12 is that step is shaft-like, and a side lever of the reduced diameter section of handle 12 offers axial push rod groove with it, offers radially square cotter hole on the handle of push rod groove bottom, square cotter 15 is installed in the square cotter hole, is set with spring 13 on the handle 12; Handle 12 is positioned at the pore of bearing 14, and the lower end of spring 13 is positioned at the step place of the pore of bearing 14, and the push rod groove on the handle 12 is corresponding with the jogger hole on the bearing 14.The end of the reduced diameter section of push rod 7 cooperates with the jogger hole on the bearing 14 is movable.
Referring to Fig. 6, the end of the reduced diameter section of push rod 7 is the nose bar shape, and end face is the inclined-plane.A parallel sided of the inclined-plane of push rod 7 ends and square cotter 15 is seen Fig. 2.
During use: workpiece is placed on round tray 3, the round tray 3 of place work piece can not arbitrarily rotate when implementing assembling, indexing lock device 1 is in lockup state (being Fig. 2 and Fig. 4 state) at this moment, on the one hand the be under pressure pressure-acting of 8 pairs of push rods 7 of spring of the roller 4 on the indexing lock device is pushed in the locating slot on round tray 3 circumference, push rod 7 is subject to the restriction of square cotter 15 on the other hand, thereby cause push rod 7 and the roller 4 can't be in slide 9 interior movements, locating slot on the round tray 3 is blocked by roller 4 at this moment, so that round tray 3 can't be rotated by locking.When needs when assembling is implemented at another position on workpiece, need to rotate round tray 3, at this moment, press lower handle 12, be released state, see Fig. 3, this moment, square cotter 15 moved on to the below of push rod 7 ends, so that the restriction cancellation of 15 pairs of push rods 7 of square cotter, rotate round tray 3 with certain power, the locating slot pair roller on the round tray 3 produces outside thrust, thereby makes roller 4 overcome the pressure-acting of 8 pairs of push rods 7 of compression spring and outwards mobile, at this moment roller 4 rolls in round tray 3 outer rings and begins to break away from locating slot on the round tray 3, and round tray 3 is free to rotate; When roller 4 breaks away from locating slot fully and is positioned at the outer ring of round tray 3, push rod 7 limits square cotter 15 so that handle 12 can't rebound, until the next locating slot of round tray 3 outer rings rotates to roller 4 positions, thereby roller 4 springs into the automatic locking of realizing another position in next locating slot under compression spring 8 effects.
