According to the automatic transfer manipulator device for the automobile hub blanks, the whole base frame 17 is formed by fixing 4 upright posts on the ground, arranging the rails 21 on the base frame, and forming a whole structure through 2 cross beams 26.

The bottom ends of the symmetrical clamping cylinder pairs 23 are fixedly connected to the cylinder base 24, and the piston rod ends of the symmetrical clamping cylinder pairs 23 are fixedly connected to the hub clamping jaws 1, so that the hub clamping jaws 1 can be opened and closed, and the hub is clamped. The hub claw 1, the claw supporting frame 2, the swinging hydraulic cylinder 3 and the connecting sleeve 4 are sequentially connected, the connecting sleeve 4 is connected with the hydraulic cylinder 5 and the large guide rod 6, the pair of symmetrical clamping cylinders 23 enable the hub claw 1 to open and close to clamp the hub, the swinging hydraulic cylinder 3 can achieve the effect that a blank of the clamping hub is turned 180 degrees, and the hydraulic cylinder 5 and the large guide rod 6 can achieve the effect that the clamping hub stretches back and forth. The manipulator thus constituted is connected to the upper platform 7 by bolts via the hydraulic cylinder 5 and the large guide rod 6.

The P balancing weight is fixed on the side end part of the upper platform 7 through bolts, and plays a role in balancing the weight of the upper platform 7. The guide pillar and guide sleeve assembly 9 is arranged in the rotary welding frame 10, the rotary welding frame 10 is connected with the lifting table k, and the lifting hydraulic cylinder 8 lifts the lifting table k under the guiding action of the guide pillar and guide sleeve assembly 9 to realize the lifting action.

The spin welding frame 10 is connected with the spin chassis 11, and the spin welding frame 10 and the spin chassis 11 are driven to rotate in the bearing 19 by the torque generated by the forward and reverse rotation servo motor 18, so as to realize the rotation in the horizontal plane when the hub blank is clamped.

Fig. 2 shows an example of a driving mechanism for driving the carriage 20 to move along the rail 21, the rotary servo motor 14 is connected to the screw 13 via a coupling L, the screw 13 is driven to rotate by a moment generated by the rotary servo motor 14 capable of rotating in the forward and reverse directions, and the flange 25 is fixed to the left end face of the integral base frame 17. The optical end of the screw rod 13 passes through the flange plate 25 and the left end of the integral base frame 17. 2 ball nuts 15 are fastened to both end surfaces of the carriage 20. The screw rod 13 drives the ball nut 15 to drive the trolley 20 to move fast.

The roller upper platen 16 is placed on the rail 21 to prevent the 4 bearingrollers 12 of the carriage 20 from falling off. The rails 21 are placed on the integral base frame 17. The lock S is fastened to the side end of the carriage 20 and moves with the carriage 20 on the rail 21.

The rotating shaft Z passes through the front end of the upper platform 7, and the rotating shaft Z passes through the upper front end of the lifting platform k, and the upper platform 7 and the lifting platform k are connected through the rotating shaft Z. The upper platform 7 can rotate by taking the rotating shaft Z as an axis through the telescopic action of a piston rod of the lifting hydraulic cylinder Q which is arranged opposite to the rotating shaft Z, so that the pitching angle of the hub claw 1 can be realized in a linkage way. The head end of a piston rod of the lifting hydraulic cylinder Q is connected with the right bottom end surface of the upper platform 7 through a cylinder rotating shaft D. The bottom end of the lifting hydraulic cylinder Q is connected with the right upper end face of the lifting table k through another cylinder rotating shaft D1, so that the process that the hub blank is transferred from the primary forging press to the final forging press and then transferred to the conveying track is realized.

The device workflow is as follows as shown in fig. 3:

the first step: after the primary forging press forges the hub blank, the lifting hydraulic cylinder 8 extends out, and the lifting table k is lifted under the guiding action of the guide post and guide sleeve component 9 in the rotary welding frame 10. The piston rod of the hydraulic cylinder 5 stretches out to drive the large guide rod 6 to stretch out, and the symmetrical clamping cylinder pair 23 is opened and closed to drive the hub claw 1 to stretch out and clamp the hub blank.

And a second step of: the hydraulic cylinder 5 and the large guide rod 6 are contracted, so that the hub claw 1 for clamping the hub blank is contracted. The lifting hydraulic cylinder 8 is contracted, and the upper platform 7 descends under the guiding action of the guide pillar and guide sleeve component 9 in the rotary welding frame 10. The purpose of this is to keep the hub in a low position for smooth movement. Some hub blanks need to be turned 180 degrees, and the swing hydraulic cylinder 3 is used for clamping the hub blanks and turning 180 degrees. This function can be masked if not required.

And a third step of: the moment generated by the forward and reverse rotation servo motor 14 drives the screw rod 13 to rotate, and the screw rod 13 drives the ball nut 15 to drive the trolley 20 to move to the final forging press position. The lifting hydraulic cylinder 8 extends out, and the lifting table k is lifted under the guiding action of the guide pillar and guide sleeve assembly 9 in the rotary welding frame 10. The piston rod of the hydraulic cylinder 5 stretches out to drive the large guide rod 6 to stretch out, and the symmetrical clamping cylinder pair 23 is opened and closed to drive the hub claw 1 to stretch out and put down a hub blank.

Fourth step: after the final forging press forges the hub blank, the lifting hydraulic cylinder 8 stretches out, and the lifting table k rises under the guiding action of the guide pillar and guide sleeve component 9 in the rotary welding frame 10. The piston rod of the hydraulic cylinder 5 stretches out to drive the large guide rod 6 to stretch out, and the symmetrical clamping cylinder pair 23 is opened and closed to drive the hub claw 1 to stretch out and clamp the hub blank.

Fifth step: the rotating moment generated by the forward and reverse rotating servo motor 18 drives the rotary welding frame 10 and the rotary chassis 11 to rotate in the bearing 19 through the coupler L, so that the clamping hub blank rotates in the horizontal plane where the clamping hub blank is positioned to a specified required angle, the symmetrical clamping cylinder pair 23 is opened and closed, and the hub claw 1 is driven to extend out and clamp the hub blank to be placed on the subsequent transmission offline rail 22.

And then the device returns to the original position of the press machine for initial forging, the work can be repeated, and the work of clamping the lower hub blank is continued. The process that the hub blank is transferred from the primary forging press to the final forging press and then transferred to the conveying rail is realized.

The technical effects are as follows: the device is a set of small-sized forging wheel blank automatic carrying manipulator device with simple structure and low manufacturing cost. With the help of the novel pneumatic type automatic carrying manipulator device, the screw rod 13 and the ball nut 15 are matched and rotated more efficiently, and the transmission speed is faster. The hot small forging wheel blank is accurately clamped and conveyed to the conveying offline rail 22 from the press initial forging die and the final forging die by using a manipulator, an air cylinder, a hydraulic cylinder and a lever principle, the air cylinder is high in speed, and the power of the hydraulic cylinder is more stable. The locking device S is used for locking the primary forging and final forging processes of the trolley 20 on the rail 21 to fix and position, and repeated positioning accuracy is improved. The locating pin of the locking device S is matched with the locating hole on the track 21, so that accurate positioning is realized. The telescopic action of the piston rod of the lifting hydraulic cylinder P can realize that the upper platform 7 rotates by taking the rotating shaft Z as an axis, so that the elevation and depression angles of the hub claw 1 can be realized in a linkage way, the function can expand the application range of the wheel type lifting hydraulic cylinder P, and the wheel type lifting hydraulic cylinder P can be particularly used for wheels with difficult angles. Only needs simple PLC to control, low price and low maintenance cost. Is convenient for human operation and has strong practicability.
