Can press from both sides article through opening and close of controller control cylinder, then control anchor clamps 35 and get, can set up anchor clamps 35 of different quantity in the outside of guide rail 34, and then realize getting not unidimensional article.

The working principle is as follows: when the manipulator works, the two motors 3 are controlled to rotate by the controller, when the two motors 3 simultaneously rotate in the same direction, then the two worms 4 simultaneously rotate, the worm wheel 6 is jointly meshed with the two worms 4, the two worms 4 can drive the worm wheel 6 to transversely move along the device groove 2 after rotating, the worm wheel 6 cannot rotate, the worm wheel 6 can drive the fixed rod 5 to move after moving, further drive the sliding table 8 to move along the two sliding rods 7, then drive the mechanical arm body 32 at the upper end of the supporting plate 11 to transversely move, when the two motors 3 rotate in different directions, the two worms 4 can also rotate in different directions and drive the worm wheel 6 to rotate, at the moment, the worm wheel 6 cannot transversely move, the fixed rod 5 and the transmission gear 9 can be driven to rotate after the worm wheel 6 rotates, and the transmission gear 9 is meshed with the rack 10, the transmission gear 9 can drive the rack 10 to move, and further drive the supporting plate 11 at the upper ends of the two first connecting rods 13 to move longitudinally, so that the controller can drive the mechanical arm body 32 to move transversely or longitudinally, which is convenient for processing work to be carried out, after the motor 3 is started and drives the worm 4 to rotate, the rotating disc 15 inside the rectangular cavity 14 can be driven to rotate simultaneously, then the rotating disc 15 can drive the annular loop rod 19 to move up and down through the inserted rod, and further drive the first sliding plug 18 to move up and down inside the first sliding cavity 16 through the first pressure rod 17, and then the first sliding plug is matched with the two first one-way valves 20, so that the lubricating oil inside the oil storage device is pumped into the first sliding cavity 16 and then led into the spray pipe 21, the spray heads 22 which are the same as the spray heads inside the device groove 2 are also installed at the two ends of the bottom plate 1, and then the spray heads 22 spray to the inside the device groove 2 and the slide rod 7, then the mechanical equipment is lubricated, so that the abrasion of the mechanical equipment in the using process is reduced, after the motor 3 is started and drives the worm 4 to rotate, the fixing plate 24 in the circular cavity 23 can be driven to rotate simultaneously, then the fixing plate 24 can drive the disc 25 to rotate, because the upper end of the second pressure lever 26 is clamped at the edge of the disc 25 and is in sliding connection with the disc 25, then the second pressure lever 26 can move up and down along the edge of the disc 25, so as to drive the second sliding plug 28 in the second sliding cavity 27 to move up and down, then the second pressure lever is matched with the two second one-way valves 29, the external gas is pumped into the second sliding cavity 27 and then pressed into the guide pipe 30, when the gas flows, the oil lubricating the mechanical equipment can flow to the bottom of the device groove 2, then flows into the guide pipe 30 through the collecting pipes 31 and then flows into the collecting equipment, and because the flow rate of the gas in the guide pipe 30 is larger, according to the bernoulli principle, the pressure is low at the place with high flow velocity, and then the gas and the oil in the device groove 2 are driven to enter the guide pipe 30 through the collecting pipes 31, so that the collection of the oil is accelerated.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
