The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As depicted in figs. 1 and 2, a kind of roll-over type mechanical arm of the present utility model, it comprises master arm 1, slave arm 2, upset control cam 3, clamp control cam 4, fastening spring 5, left side pawl 10 and right pawl 11, master arm 1 is fixed on the rotating disk 15 by active arm axle 6, slave arm 2 is fixed on the rotating disk 15 by driven arm axle 7, by left pawl rotating shaft 8 left pawl 10 is installed on one end of master arm 1, the other end of master arm 1 links to each other with an end of slave arm 2 by gear pair 16, by right pawl rotating shaft 9 right pawl 11 is installed on the other end of slave arm 2, the turnover transmission rig that is used for controlling left pawl rotating shaft 8 rotations links to each other, and described turnover transmission rig is controlled cam 3 with upset and contacted cooperation.In the present embodiment, turnover transmission rig comprises turning gear 12 and tooth bar 13, described turning gear 12 links to each other with left pawl rotating shaft 8, the tooth bar 13 that is used for cooperating with turning gear 12 is installed on the master arm 1, master arm 1 contacts cooperation with clamping control cam 4, and an end of tooth bar 13 contacts cooperation with upset control cam 3.Left side pawl rotating shaft 8 and right pawl rotating shaft 9 have same axis heart line, when left pawl rotating shaft 8 rotates, can drive right pawl rotating shaft 9 and rotate synchronously.In the present embodiment, end on the master arm 1 contacts cooperation by master arm roller 18 with clamping control cam 4, master arm roller 18 is fixed on the master arm 1 by master arm roller shaft 19, tooth bar 13 an end control cam 3 by tooth bar roller 20 with upset and contact cooperation, tooth bar roller 20 is fixed in an end of tooth bar 13 by tooth bar roller shaft 21.In preferred embodiment, be installed with slide block 14 on the master arm 1, offer chute 17 on the tooth bar 13, tooth bar 13 is sheathed on the slide block 14 by chute 17, tooth bar 13 can move by chute 17 and cooperating with respect to master arm 1 of slide block 14, rotated thereby promote turning gear 12.Referring to illustrated in figures 1 and 2, can also further upset control cam 3 be designed to plane cam, and the control cam 3 that will overturn is integrally formed with clamping control cam 4, wherein the outside is for being used for contact with master arm 1 the clamping control cam 4 that cooperates, and inboardly controls cam 3 for the upset that is used for contact with tooth bar 13 cooperation.Help compact conformation like this, reduce member, reducing production costs clamps control cam 4 and upset control cam 3 and is fixed in and keeps motionless on the central shaft, and rotating disk 15 can rotate around the central shaft that clamps control cam 4 and upset control cam 3.Simultaneously, rotating disk 15 drives master arm 1 and slave arm 2 rotations that are fixed thereon.Pawl rotating shaft 8 can be by as a whole with turning gear 12, and master arm 1 and gear pair 16 also can as a whole.When rotating disk 15 rotates, master arm roller 18 contacts with clamping control cam 4, master arm 1 is around active arm axle 6 rotating certain angle clockwise, slave arm 2 rotates around driven arm axle 7 anticlockwises under the transmission of gear pair 16, the left pawl 10 and the right pawl 11 that are individually fixed on master arm 1 and the slave arm 2 are opened, but discharging this moment or charging.Then, under the acting in conjunction that clamps the fastening spring 5 between control cam 4 and master arm 1, the slave arm 2, master arm 1, slave arm 2 are retracted, the gripper closure, but the material between the gripper has well been advanced in clamping.When tooth bar roller 19 contacts with upset control cam 3, tooth bar 13 under the cooperation of chute 17 and slide block 14 with respect to master arm 1 motion, until cooperating with turning gear 12, drive turning gear 12 and 8 rotations of left pawl rotating shaft, finally finish left pawl 10 and 11 upsets of right pawl.The upset that is manipulator is meshed by the tooth bar 13 of upset control cam 3 control moving linearlies and the turning gear 12 that is fixedly connected on left pawl rotating shaft 8 by being installed on the master arm 1, tooth bar 13 drives turning gears 12 Rotate 180s °, its center rotates to B by A, if gripping object is a bottle class, upset back bottleneck and the bottle end towards exchanging just.Otherwise tooth bar 13 drives 180 ° of turning gear 12 reverse rotations, and its center rotates to A by B, and the bottle class is got back to the origin-location again, and above-mentioned two kinds of positions as shown in Figure 3, Figure 4.
Operation principle: when rotating disk 15 when clamping the central shaft rotation of control cam 4 and upset control cam 3, clamp control cam 4 and promote master arm roller 18, drive master arm 1 and turn over certain angle around the center of active arm axle 6, gear pair 16 on the master arm 1 drives slave arm 2 and turns over respective angles, left pawl 10 and the right pawl 11 that be individually fixed on master arm 1 and the slave arm 2 this moment open the extracting material, clamp material thereby rely on clamping control cam 4 and fastening spring 5 that master arm 1 and slave arm 2 are resetted then.Simultaneously, tooth bar roller 20 contacts with upset control cam 3, drive tooth bar 13 moving linearly in slide block 14, thereby drive left pawl rotating shaft 8 Rotate 180 degree, make left pawl 10 and right pawl 11 clamping materials overturnings 180 degree (promptly turning to center B) from center A by turning gear 12.The upset of this manipulator the time only is left pawl 10 and right pawl 11 (this moment they clamping got well material) around the common center lines revolution of left pawl rotating shaft 8, right pawl rotating shaft 9, compare around the centre of gyration upset of a gusset piece at rotating disk 15 with all-in-one-piece master and slave swing arm (comprising gripper), the radius of gyration is very little.
The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be understood that; for those skilled in the art; in the some improvements and modifications that do not break away under the utility model principle prerequisite; for example turnover transmission rig adopts the compound mode of sprocket wheel and chain; power is passed to the sprocket wheel that links to each other with left pawl rotating shaft 8 by chain; thereby drive its rotation etc., these improvements and modifications also should be considered as protection domain of the present utility model.
