(5) specific embodiment
Below in conjunction with accompanying drawing concrete structure of the present utility model and operation principle are further detailed:
In conjunction with Fig. 1, the utility model is held tightly grabbing device 2, lever flip flop equipment 3, is automatically replied with checkout gear 4 four parts and form by V-arrangement manipulator support 1, spring.V-arrangement manipulator support 1 is the basic framework of whole manipulator, it is the carrier that other devices are installed, its available aluminium alloy riveted joint or other metal solder form, its bottom shape be arc, square or other shapes by the shape decision of the article that grasped, can adjust voluntarily in case of necessity.The length of V-arrangement manipulator support 1 leading portion (mainly playing the guiding role) also as required in different ways, as Fig. 3, Fig. 6, shown in Figure 7.
Spring is held grabbing device 2 tightly and is comprised that 5,6, two big torque springs of two rotating shafts grasp gripper 9,10 for 7,8 and two groups.In conjunction with Fig. 2, be example with manipulator left side enclasp device (i.e. right side enclasp device among the figure): rotating shaft 5 two ends all are fixed on the V-arrangement manipulator support 1, and (preventing shaft distortion under the effect of big torsion) supported with a bearing 11 in the centre; Big torque spring 7 is enclosed within on the rotating shaft 5, and the installation of spring is to make the extracting gripper that very strong restoring force (power of holding tightly to the centre all the time) effect be arranged when both sides separate; Grasping the gripper rear end can rotate around rotating shaft 5, front end embowment (its shape can become as required), the effect of arc is to increase to hold contact area tightly on the one hand, make extracting more stable, both sides are closed right arc shaped hook and are had latching characteristics on the other hand, prevent that the article that grasp from coming off, as shown in Figure 5.Two extracting grippers are fixing by the crossbeam welding of centre up and down, the uniformity when keeping grasping the gripper opening and closing.About two groups grasp grippers and adopt symmetric arrangement, principle is the same.
In conjunction with Fig. 4, pulling force rubber band 14, two connecting rods 15 and 16, two ends poles are replied pulling force rubber band 17 and 18 to lever flip flop equipment 3, rotating shaft 19 is formed by having dead center bar 12, have dead center bar 13, replying.Have dead center bar 12 and have dead center bar 13 and can rotate around axle 19, rotating maximum angle is 185 degree.Purpose is: be subjected to do the time spent to the middle springs extruding force at two bars, two bars make two bars stuck by dead-centre position 30 under the effect of replying pulling force rubber band 14, and promptly two bars can only one-way movement.The other end of two bars all has a taper guide ledges, the end that two ends pole is replied pulling force rubber band 17 and 18 is fixed on taper guide ledges inside, the other end is fixed on and grasps on gripper rotating shaft 5 and 6, its effect is: replying motor 20 by steel wire rope 21,22 when grasping grippers and draw back (gripper opens) two groups, reply pulling force rubber band 14 and make dead center bar 12, dead center bar 13 is got back to the state that push up mutually at preceding dead point that triggers, under the pulling force effect of replying pulling force rubber band 17 and 18, finish simultaneously all parts of lever flip flop equipment from group, promptly by the transformation of V font to in-line, boss plays guiding and position-limiting action; When lever flip flop equipment 3 front ends (axle 19 positions) are subjected to an impulsive contact force F effect and during triggering, lever flip flop equipment 3 just becomes the V font by in-line, its elongated part is replied pulling force rubber band 17 and 18 stretch compensations by two ends pole, having dead center bar 12 is what to separate with its connecting rod 15 at this moment, the same left side, the right.
In conjunction with Fig. 2-3, automatically reply that 20, two steel wire ropes 21 of motor and 22, two support pulley 23 and 24, four travel switches 25,26,27 and 28 are formed by replying with checkout gear 4.Answer motor 20 is fixed in the rear end of V-shaped groove, and reel of driven by motor 29 rotates, and two steel wire ropes 21 of rotation pulling and 22 of reel 29 grasp opening and closure of grippers 9,10 thereby driven two groups.Four travel switches 25,26,27 and 28 effect are to grasp gripper 9,10 deployed position to two groups to play detection effect, if motor is selected the servomotor that has the horse dish for use, four travel switches also can, as shown in Figure 7.
The process of whole manipulator storage power is finished by replying motor 20, reply motor 20 and grasp gripper 9 with two groups by two steel wire ropes 21 and 22,10 to two laybacks, the particular location that draws back is by four travel switches 25 on the V- arrangement manipulator support 1,26,27 and 28 determine, at this moment lever flip flop equipment 3 becomes in-line by the V font under the pulling force effect of a plurality of rubber bands, and grasp gripper 9 with two groups by the dead point, 10 supports are come (as shown in Figure 3), reply motor 20 then and reverse again steel wire rope 21 and 22 is unclamped, finish the energy storage process of system.
Whole manipulator grasps, the process of holding tightly is as follows: when manipulator opens as Figure 1-3, two groups of extracting grippers 9,10 are opening under the supporting role at lever flip flop equipment 3 dead points, but two groups of extracting grippers 9,10 have the trend to middle obvolvent all the time under the effect of torque spring 7,8.When running in the middle of the lever flip flop equipment 3 will embrace the impact F that gets article the time, lever flip flop equipment 3 will inwardly rotate with axle 19, becomes the V font by original in-line.Lose two groups of support force grasp grippers 9,10 under the effect of separately torque spring rapidly to middle obvolvent, shown in figure (5), realization is to the quick extracting of article, because two groups of extracting gripper 9,10 front ends have the arc latching characteristics, so the article that grab are difficult to come off.Be that impact can discharge the spring that stores rapidly in whole extracting process, energy is converted into the power of holding tightly of manipulator, the time of realizing this process is very short, almost just in bump energy discharge and finish, this is the energy process of release fast thus.
The specific embodiments of this kind manipulator has multiple mode, except being detected the extracting gripper deployed position by four travel switches of saying above, also has long guide post mode shown in Figure 6; Shown in Figure 7 need not four travel switch detect and use the mode that the horse coil motor directly detects instead; The manual recovery occupation mode that motor and checkout gear are all dismantled will be replied; The lever flip flop equipment is changed into the mode of the hard collision of a live metal lever etc.
The simplification manipulator scheme of replying motor and checkout gear of removing shown in Figure 6 has been removed answer motor and checkout gear, guide post has extended, lever flip flop equipment with front end changes a complete metallic rod into simultaneously, the two ends mill of metallic rod has shallow grooves, the crossbeam that we will grasp gripper is pressed in the groove, do the time spent when metallic rod is subjected to impact, metallic rod will be from landing on the supporting traverse that grasps gripper, grasps gripper and catches the extracting thing rapidly thereby make.Adopting this mode advantage is manipulator extracting thing rapidly under the effect of pneumatic conveyer, the V-type stock of front end has guiding and interference effect simultaneously, but the bump to metallic rod is bigger simultaneously, clash into about 10 times and will change a metallic rod, so lever flip flop equipment that suggestion uses Fig. 4 to introduce, lever flip flop equipment shown in Figure 4 also not only is confined to square, can make suitable modification to shape as required.
