The specific embodiment
The utility model is described in further detail below in conjunction with concrete drawings and Examples.
As shown in the figure: the lifting positioning and locking device in embodiment mainly is comprised of frame 1, cylinder 2, rotating shaft 3, cylinder connector 4, connecting rod 5, fork 6, positioning groove plate 7, upper support 8, upper bit switch 9, the next support 10, lower bit switch 11, adjusting bottom 12, track adjusting wheel 13, guide groove 14, first number plate 15 and the second number parts such as plate 16.
As Fig. 1 ~ shown in Figure 3, described rotating shaft 3 two ends are arranged in the bearing seat at frame 1 top, and rotating shaft 3 drives rotation by rotating drive mechanism; Described positioning groove plate 7 first ends are fixed in rotating shaft 3, and positioning groove plate 7 second ends are provided with the positioning and locking groove, and described rotating shaft 3 drives positioning groove plate 7 when rotating and rotates, and fix shaft 17 clampings that the positioning and locking groove on positioning groove plate 7 is used for balladeur train rolls on bed coordinate.
The structure of described rotating drive mechanism such as Fig. 1 ~ shown in Figure 3, it mainly is comprised of cylinder 2, cylinder connector 4, connecting rod 5 and fork 6, described cylinder 2 is fixed on frame 1, the rod end of cylinder 2 connects cylinder connector 4, described cylinder connector 4 is hinged with connecting rod 5 one ends, described connecting rod 5 other ends and fork 6 one ends are hinged, described fork 6 other ends are fixed in rotating shaft 3, when the piston rod of cylinder 2 is flexible, drivening rod 5 moves, connecting rod 5 moving belt movable pendulum bars 6 swing, and fork 6 swings and drives rotating shaft 3 rotations.
As shown in Figure 1, described frame 1 top is equipped with upper bit switch 9 by upper support 8, described positioning groove plate 7 first ends are equipped with plate 15 the first number, when positioning groove plate 7 is rocked to horizontal position, positioning and locking groove on positioning groove plate 7 blocks 17, the first numbers plates of fix shaft 15 that balladeur train rolls on bed and triggers upper bit switches 9; Described frame 1 below is equipped with lower bit switch 11 by the next support 10, described positioning groove plate 7 second ends are equipped with plate 16 the second number, when positioning groove plate 7 is rocked to vertical position, 17, the second numbers plates of fix shaft 16 that positioning and locking groove disengaging balladeur train on positioning groove plate 7 rolls on bed trigger lower bit switches 11.
As shown in Figure 1, described frame 1 is provided with guide groove 14, captive joint track adjusting wheel 13 on described cylinder connector 4, and when cylinder 2 piston rods stretched, track adjusting wheel 13 can be rolled 14 li of guide grooves and be walked, and plays directional tagging.
As shown in Figure 1, the supporting leg bottom of described frame 1 is provided with adjusting bottom 12.
Working process of the present utility model and principle of work are as follows:
Lifting positioning and locking device of the present utility model is arranged on balladeur train and rolls a termination.When car body was put in place by elevator lifting, balladeur train rolls bed needed positioning and locking.Cylinder 2 is started working, and the piston rod of cylinder 2 stretches out and promotes connecting rod 5 and moves forward, and track adjusting wheel 13 play the guiding role; Connecting rod 5 drives fork 6 and swings, fork 6 drives rotating shaft 3 and rotates, the positioning groove plate 7 that is fixedly mounted in rotating shaft 3 rotates thereupon, when positioning groove plate 7 turns to horizontal position, positioning and locking groove on positioning groove plate 7 blocks 17, the first numbers plates of fix shaft 15 that balladeur train rolls on bed and triggers upper bit switches 9, upper bit switch 9 numbers, control cylinder 2 quits work, and workpiece begins to reprint; After reprinting end, cylinder 2 counteragents, the piston rod of cylinder 2 bounce back and pull connecting rod 5 to move backward, and connecting rod 5 drives fork 6 backswings, thereby make rotating shaft 3 backward rotation, positioning groove plate 7 is backward rotation simultaneously, and when positioning groove plate 7 turned to vertical position, the positioning and locking groove disengaging balladeur train on positioning groove plate 7 rolled the fix shaft 17 on bed, the second number plate 16 triggers lower bit switch 11, lower bit switch is given cylinder 2 11 numbers, and control cylinder 2 quits work, and waits for next working cycle.
