Accompanying drawing 2 is the connection sectional view of guide rod and guide pin bushing.
Accompanying drawing 3 is the connection sectional view of gripping disk and strap.
Detailed description of the invention
Below in conjunction with accompanying drawing, the operation principle of the present invention is elaborated.
Detailed description of the invention one: the catching robot of a kind of turning casing, is arranged on the end of the rotating mechanical arm of Cartesian robot.Cartesian robot by along X-axis, Y-axis, the movement of Z axis and rotation about the z axis, controls mechanical hand and arrives and specify crawl position and capture angle.Solenoid controlled directional control valve controls atmospheric pressure pole by pneumatic cylinder, drives ambulatory splint to do horizontal reciprocating and moves, the gripping width of adjustable mechanical hands.Ambulatory splint is connected with guide rod by sleeve, and guide rod slides in guide pin bushing, and guide rod and guide pin bushing play the effect of guide rail and support.Two pairs of guide rods and guide pin bushing are parallel to each other.Sleeve is symmetrically extended and is arranged on ambulatory splint, and sleeve and guide rod interference hot jacket are assembled together, and increases contact area, strengthens the bonding strength of guide rod and ambulatory splint.
Direct acting pressure valve and solenoid controlled directional control valve are by hose connection, and solenoid controlled directional control valve is connected with pneumatic cylinder by flexible pipe.Direct acting pressure valve and solenoid controlled directional control valve are all arranged on the top of strap, manual adjustments direct acting pressure valve, can change the gas pressure in pneumatic cylinder, regulate the grasp force of mechanical hand, it is achieved the crawl to Different Weight casing.When capturing casing, the air pressure in pneumatic cylinder reaches during setting value direct acting pressure valve and gas circuit is closed so that grasping movement is automatically stopped, it is to avoid when conventional mechanical hands captures, in addition it is also necessary to other auxiliary bodies stop grasping movement.
Detailed description of the invention two: Cartesian robot controls mechanical hand and moves to crawl position set in advance, mechanical arm rotates to an angle, the gripping face of two gripping dishes is contacted with two planes of symmetry of casing crawl, Cartesian robot adjusts the height of mechanical hand again, moves to specific bit placement location.Pneumatic control circuit works, and is complete the crawl to casing and placement according to detailed description of the invention one.
Actively gripping dish is arranged on strap by a taper roll bearing and a deep groove ball bearing.Taper roll bearing offsets the axial force that gripping dish produces, and deep groove ball bearing offsets the radial force that gripping dish produces, and this structure makes robot manipulator structure compacter.Bearing and strap are fixed, and bearing two ends are fitted with dust-proof end cap.The gripping face of gripping dish is stained with rubber antiskid layer, to increase the frictional force between casing.
Servomotor is fixedly mounted on strap by electric motor end cap.Servomotor works, and drives the synchronizing wheel on active gripping dish axle to rotate by Timing Belt, controls actively to grip the angle that disc spins is certain by stable drive ratio.Casing and the driven gripping same angle of dish servo rotary, it is achieved the rotation to casing one degree of freedom, control linking arm by Cartesian robot and rotate, it may be achieved the rotation of another degree of freedom of casing so that crawled casing adjusts the attitude required.Finally, by the control of Cartesian robot, complete the movement to casing and the placement of assigned position attitude.
Strap there is also mounted pressure transducer, judge whether to capture by the moment of flexure of strap or the phenomenon such as the casing landing that causes due to fault in motor process, carry out next step process.
