In figure, mark is as follows: motor 1, one-level cylinder 2, one-level cylinder piston rod 3, secondary cylinder 4, secondary cylinder piston rod 5, cylinder saddle 6, guide rail 7, bearing 8, leading screw 9.
Embodiment
The present invention is propped up 6 formed by motor 1, one-level cylinder 2, secondary cylinder 4, leading screw 9, guide rail 7, cylinder.
General structure of the present invention is:
Motor 1 is actuating motor or stepper motor, and cylinder saddle 6 is connected with leading screw 9 by guide rail 7, and leading screw 9 is connected by feed screw nut.One-level cylinder 2, secondary cylinder 4 are connected with cylinder saddle 6 respectively, after one-level cylinder, cylinder barrel is connected by gas circuit with cylinder barrel before secondary cylinder, before one-level cylinder, cylinder barrel is connected by gas circuit with cylinder barrel after secondary cylinder, and the internal diameter of cylinder of one-level cylinder 2 is greater than the internal diameter of cylinder of secondary cylinder 4.
The internal diameter of cylinder of setting one-level cylinder 2 is D, and the internal diameter of cylinder of secondary cylinder 4 is d, and the extending amount of secondary cylinder 4 is D/d times of the displacement amount of one-level cylinder 2.Therefore, when motor 1 control cylinder bearing 6 is with a certain speed V motion, the speed that secondary cylinder piston rod 5 stretches is V+D/dV=(1+D/d) V, and add the motion speed of secondary cylinder piston rod 5, realization can continuous control.
Actuating motor or stepper motor band dynamic air cylinder straight line moving distance are s, simultaneously owing to occurring between one-level cylinder piston and cylinder barrel that relative displacement is also s, and the internal diameter of cylinder of one-level cylinder 2 and secondary cylinder 4 is than being D:d, therefore secondary cylinder piston is (D/d) s relative to the displacement of one-level cylinder 2, therefore the total displacement of secondary cylinder 4 is s+D/ds=(1+D/d) s, because this increasing stroke and the rapidity of secondary cylinder piston.
The present invention has following two kinds of placement schemes in above-mentioned general structure.
Show in figure, the first placement scheme is, one-level cylinder piston rod 3 and casing are fixed, and the cylinder barrel of one-level cylinder 2 is connected by cylinder saddle 6 with the cylinder barrel of secondary cylinder 4.
In above-mentioned layout, one-level cylinder piston rod 3 is fixed, when making actuating motor or stepper motor drive cylinder saddle 6 to move together with one-level cylinder 2 and secondary cylinder 4, form relative movement between the cylinder barrel of one-level cylinder 2 and one-level cylinder piston rod 3, thus the piston two ends cylinder barrel air pressure of one-level cylinder 2 changes.Because the front cylinder barrel of one-level cylinder 2, rear cylinder barrel are connected by gas circuit with the rear cylinder barrel of secondary cylinder 4, front cylinder barrel respectively, this just makes one-level cylinder piston two ends cylinder barrel air pressure different, thus promotion secondary cylinder piston driving piston rod realizes to-and-fro motion.
Show in figure, the second placement scheme is, cylinder barrel and the casing of one-level cylinder 2 are fixed, and the piston rod of one-level cylinder 2 is connected by cylinder saddle 6 with the cylinder barrel of secondary cylinder 4.
In above-mentioned layout, one-level cylinder 2 and secondary cylinder piston are fixed on cylinder saddle 6, and cylinder saddle 6 drives each cylinder to realize to-and-fro motion.After one-level cylinder, cylinder barrel is connected by gas circuit with cylinder barrel before secondary cylinder, before one-level cylinder, cylinder barrel is connected by gas circuit with cylinder barrel after secondary cylinder, the cylinder barrel of one-level cylinder 2 is fixed, when making actuating motor or stepper motor drive cylinder saddle 6 to move, form relative movement between the cylinder barrel of one-level cylinder 2 and one-level cylinder piston, thus one-level cylinder piston two ends cylinder barrel air pressure changes.Because the front cylinder barrel of one-level cylinder 2, rear cylinder barrel are connected by gas circuit with the rear cylinder barrel of secondary cylinder 4, front cylinder barrel respectively, this just makes one-level cylinder piston two ends cylinder barrel air pressure different, thus promotion secondary cylinder piston driving piston rod realizes to-and-fro motion.
In above two kinds of placement schemes, by controlling the rotation angle of actuating motor or stepper motor to obtain the corresponding amount of feed, the continuous print Accurate Position Control of cylinder saddle 6 can be realized, thus the continuous motion of secondary cylinder piston rod 5 is realized by one-level cylinder 2 and secondary cylinder 4, continuous control is realized to the stroke of secondary cylinder 4, and speed of response faster can be realized, motion state is steadily reliable.
