Detailed description of the invention
Technical scheme of the present invention is further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
The constitutionally stable manipulator of a kind of adjustable angle; Comprise cylinder mount pad 1, connecting axle 2, sucker mount pad 3, sucker 4, telescopic top-pressure part 5 and spherical bearing 6, some described suckers 4 are fixed on described sucker mount pad 3;
One end of described connecting axle 2 is vertically fixed on the middle part of described cylinder mount pad 1, and the other end through the middle part of described sucker mount pad 3, and is fixed on described spherical bearing 6, and described spherical bearing 6 is fixed on described sucker mount pad 3;
Described top-pressure part 5 is arranged between described cylinder mount pad 1 and sucker mount pad 3, and one end of described top-pressure part 5 is vertically fixed on described cylinder mount pad 1, and the other end is formed to extrude with described sucker mount pad 3 and contacts.
Workpiece 12 is inclined plane for the surface of adsorbing relative to sucker mount pad 3, when needing travelling workpiece 12, cylinder mount pad 1 is driven to drive each parts mounted thereto to move straight down, the sucker 4 on sucker mount pad 3 is made to move closer to the inclined plane of workpiece 12, and due to the absorption surface of workpiece 12 be inclined plane, some suckers 4 first touch the high position in inclined plane and form extruding, while these suckers 4 extrude inclined plane, according to the relativity of power, inclined plane also can give sucker 4 with support force upwards simultaneously, according to the transitivity of power, sucker mount pad 3 also can be subject to power upwards, thus hinder sucker mount pad 3 to continue to move downward, the inclined plane of lower position cannot contact with sucker, then move up workpiece 12 time grasp force inadequate, workpiece 12 easily drops.
As shown in Figures 1 and 2, in the technical program, one end of described connecting axle 2 is vertically fixed on the center of described cylinder mount pad 1, the other end is fixed on described spherical bearing 6 through behind the center of described sucker mount pad 3, and described spherical bearing 6 is fixed on the side of described sucker mount pad 3 described cylinder mount pad 1 dorsad, then when some suckers 4 first touch the high position in inclined plane and form extruding, after sucker mount pad 3 can be subject to power F1 upwards, due to the revolute pair that the spherical bearing 6 that sucker mount pad 3 is fixing is formed with the other end of connecting axle 2, then when connecting axle 2 keeps vertical state, the side of sucker mount pad 3 can under the effect being subject to F1, the opposite side of sucker mount pad 3 can be tilted to lower position one end of inclined plane, the sucker 4 of the opposite side being arranged on sucker mount pad 3 is just in time made to contact with workpiece 12, after again vacuum pumping being carried out to each sucker 4, complete the stable absorption of the multiconductor of workpiece 12, complete transfer smoothly, whole process steps is simple, efficiency is high.
And described top-pressure part 5 is arranged between described cylinder mount pad 1 and sucker mount pad 3, one end of top-pressure part 5 is vertically fixed on described cylinder mount pad 1, the other end is formed to extrude with described sucker mount pad 3 and contacts, then top-pressure part 5 moment is to the downward pressure of sucker mount pad 3, these pressure stabilitys position of sucker mount pad 3, rocking of left-right and front-back can not be there is, make the accurate absorption position caught on workpiece 12 of sucker 4.
Described top-pressure part 5 has pneumatic springs 51 and depression bar 52 head and the tail to be formed by connecting, and wherein, one end of pneumatic springs 51 is fixed on described cylinder mount pad 1, and depression bar 52 is located between described cylinder mount pad 1 and sucker mount pad 3.Top-pressure part 5 is made up of pneumatic springs 51 and depression bar 52 two parts, and pneumatic springs 51 provides elastic force, and can change the different pneumatic springs 51 of value of elastic according to concrete operating mode, depression bar 52 also can be changed in the case of damages at any time, easy to use.
Also comprise the axis of guide 7, one end of the described axis of guide 7 is vertically fixed on described cylinder mount pad 1, and the other end is installed in U-type groove 8; Described U-type groove 8 is arranged on the edge of described sucker mount pad 3, and the openend of U-type groove 8 is towards the arranged outside of described sucker mount pad 3.As shown in Figure 1, the other end of gathering sill 7 is limited in U-type groove 8, limits the rotation of cylinder mount pad 1, improves the accuracy that sucker 4 catches the absorption position on workpiece 12, raises the efficiency.
Be provided with the both sides that two described axis of guides 7 are fixed on described cylinder mount pad 1 relatively, four top-pressure parts 5 are one group with two and are oppositely arranged on described cylinder mount pad 1, and described top-pressure part 5 is arranged between two described axis of guides 7.
Structure is simple, and four top-pressure parts 5 form enough support forces, stablize the position of sucker mount pad 3, and rocking of left-right and front-back can not occur, and makes the accurate absorption position caught on workpiece 12 of sucker 4; Relatively fix two axis of guides 7, accordingly two U-type groove 8 are set at the edge of sucker mount pad 3, define the position of sucker mount pad 3 better and can not rotate, improve the accuracy that sucker 4 catches the absorption position on workpiece 12, raise the efficiency.
The center of described sucker mount pad 3 bottom surface is protruded to the direction that workpiece 12 is placed and is formed cavity body structure 9, and described spherical bearing 6 is fixed in described cavity body structure 9.
In the present embodiment, cavity body structure 9 is frame structure, this frame structure is that formation is protruded to the direction that workpiece 12 is placed in the center of described sucker mount pad 3 bottom surface, then the other end of connecting axle 2 is easier with the effect being placed on spherical bearing 6 forces occurring in cavity body structure 9, accelerate the speed that the lower one end of workpiece 12 inclined plane contacts with sucker 4, improve the efficiency of pickup.
Described sucker 4 is suction type sucker.Suction type sucker, convenient and practical, be the preferred version of quick pickup.
Be provided with backing plate 10 between described top-pressure part 5 and sucker mount pad 3, described backing plate 10 is fixed on described sucker mount pad 3; Described top-pressure part 5 is formed directly to extrude with backing plate 10 and contacts, and forms non-immediate extrude and contact with described sucker mount pad 3.
The mounting design of backing plate 10, the on the one hand padded platform of sucker mount pad 3, suitably can shorten the length of top-pressure part 5; On the other hand, shorten the distance between sucker mount pad 3 and level pressure part 5 lower surface, the scalable effect of level pressure part 5 is more obvious.
