Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is the part of the embodiment rather than whole embodiments of the present invention.Based on this hair Embodiment in bright, the every other reality that those of ordinary skill in the art are obtained on the premise of creative work is not made Example is applied, should all belong to the scope of protection of the invention.
Embodiment
This mechanical arm is mainly used for auxiliary robot running gear and the jobs that requires special skills such as is captured, carried, and can lead to It crosses and replaces end effector species to perform different tasks.
As depicted in figs. 1 and 2, a kind of based on the robotic gripping device for having ordered-socs, which includes pedestal 1, returns Pivoted arm 2, the first single open chain unit, the second single open chain unit, the 3rd single open chain unit and end effector 9, pedestal and revoliving arm Connection, revoliving arm are connected with the first single open chain unit, and the second single open chain unit is connected with the 3rd single open chain unit, the 3rd single open chain Unit is connected with end effector.Second single open chain unit includes the upper and lower arms of articulated connection, the 3rd single open chain unit bag Electric pushrod 7 and wrist joint 8 are included, upper arm, wrist joint and electric pushrod are articulated and connected successively, and upper arm, which is equipped with to fix with upper arm, to be connected The strut connect, strut are hinged with electric pushrod, wrist joint connection end effector.First single open chain unit is two linkages, Two link mechanisms include side arm 3 and connecting rod 4, and side arm 3 is hinged with 5 lower end of underarm, and connecting rod 4 is hinged with upper arm 6.Revoliving arm and pedestal Between be rotatably connected for 360 °.3rd single open chain unit is rotatably connected with end effector for 360 °.
Electric pushrod is mainly a kind of novel linear executing agency being made of mechanisms such as motor, push rod and control devices. The working mechanism of electric pushrod is as follows:
Motor drives a pair of of feed screw nut after The gear deceleration.The rotation motion of motor is in line movement, is utilized Motor forward/backward rotation completes putter action.It the complexity such as such as can complete to rotate, shake by various levers, rocking bar or connecting rod mechanism Action.By changing lever arm of force length, stroke can be increased or reduced.
Degree of freedom is one of important technological parameters of mechanical arm, is the number that separate axes possessed by robot move Mesh.Describing the pose of an object in three dimensions needs 6 degree of freedom, and still, the degree of freedom of industrial robot is basis Its purposes and design, be likely less than 6 degree of freedom, it is also possible to more than 6 degree of freedom.Degree of freedom can excessively cause robot sheet Body is complicated, control is cumbersome, and therefore, this mechanical arm is using the link joint humanoid robot of 5 degree of freedom, meets extraordinary make Industry demand.
Independent loop number is the arbitrary basic kinematic chains (BKC) of v, can be considered and is sequentially connected by v single open chain (SOC) unit It forms.As shown in Fig. 3, Fig. 4 and Fig. 5, first SOC1Both ends component and SOC2Both ends component be connected as same component, structure Into first independent loop;The SOC of Fig. 5 and Fig. 63Both ends component be connected as same component, form second independent loop, such as Fig. 7, and so on, it is known that, v single open chain (SOC) unit may be constructed v independent loop by orderly connection.
Mechanism theory of constitution based on SOC units, this machinery arm configuration schematic diagram as shown in Fig. 2, three-dimensional modeling schematic diagram such as Shown in Fig. 1.
Mechanical arm structure chart transmission principle is as follows:
1)J1Spindle motor drives the revolution of 360 ° of revoliving arm;
2)J2Spindle motor drives underarm pitching;
3)J3Spindle motor drives upper arm to realize elevating movement by side arm and connecting rod;
4)J4Axis drives wrist joint to realize elevating movement by the back and forth movement in electric pushrod P a certain range strokes;;
5)J5Spindle motor drives the revolution of 360 ° of end effector;
6) end effector can install different hands according to job requirements and grab come band dynamic load.
This mechanical arm on running gear to be mounted on due to realizing mobile operational process, and DC servo-motor is in rotation process In there is good mechanical performance and control characteristic, and the startup voltage of motor, than relatively low, the startup time used is shorter, Therefore, the driving device selection DC servo-motor of this mechanical arm.
When selecting servomotor and retarder, it to be made to meet the requirement of torque, rotating speed, Inertia Matching etc.. In addition, determining for servomotor torque parameter, also related with the reduction ratio of retarder, therefore, the same stepping of retarder is combined Row selection.With reference to the structure size and its motion planning of robot, preliminary force analysis is carried out to it, it is electronic to calculate joint (power) torque suffered by machine and retarder is the premise of servomotor and retarder type selecting.
The torque in servomotor output terminal is loaded with loading the relational model such as formula in the torque of retarder output terminal 1:
In formula, TM:The torque of servomotor output terminal, Nm;TR:The torque of retarder output terminal, Nm;i:Slow down Device reduction ratio;η:The efficiency of retarder.
The present invention, as executing agency, is improved the flexible executive capability of robot, complete machine is driven using robot arm device Dynamic power has carried out detailed calculating.Modular structure design so that robot dismounting and change is convenient, easy care.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any Those familiar with the art in the technical scope disclosed by the present invention, can readily occur in various equivalent modifications or replace It changes, these modifications or substitutions should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with right It is required that protection domain subject to.
