Wherein, the 1 and 5 process positioning pins 307 are retracted, and the 2, 3 and 4 process positioning pins 307 are extended. The clearance indexing disc mechanism 3 can be regarded as front-end processing for ball valve recovery, and the front-end processing mainly comprises a ball valve handle pulling process, a ball valve O-shaped ring grabbing process and a ball valve cutting process;

the third step: entering a ball valve handle pulling process; the ball valve 300 to be processed is fixed by the positioning bolt 307, the electrical control system 200 respectively controls the extension and retraction of the piston rods of the first moving cylinder 402 and the first telescopic cylinder 405, when the piston rod of the first moving cylinder 402 transversely extends, the first telescopic cylinder 405 and the grabbing mechanism at the front end are driven to transversely move, and when the piston rod reaches a specified position, the grabbing mechanism aligns with the ball valve clamp 302 below and the ball valve 300 to be processed in the ball valve clamp 302; then the first telescopic cylinder 405 acts, the piston rod of the first telescopic cylinder extends out, the grabbing mechanism is pushed to descend and reaches the ball valve clamp 302, and the grabbing mechanism is matched with the ball valve to clamp the handle 40 of the ball valve; then the first telescopic cylinder 405 resets to drive the grabbing mechanism to pull out the ball valve handle 40; the first movable cylinder 402 is reset to drive the first telescopic cylinder 405 and the grabbing mechanism to reach the end of the shape stroke, and the grabbing mechanism pulls out the pulled-out ball valve handle 40 to complete one round of operation; and then waits for the next job instruction. The embodiment adopts the eccentric wheel self-tightening clamp 408 as the main structure of the grabbing mechanism, and the eccentric wheel self-tightening clamp 408 can be called as an eccentric cam clamping mechanism, can generate good force increasing and self-locking performance under the action of external force, is widely used for clamping or locking devices, and has the advantages of simple structure, rapid action, convenient operation and the like; the clamping is realized by adopting a mode that a pre-tightening cylinder 406 drives an eccentric wheel self-tightening clamp 408, the piston rod of the pre-tightening cylinder 406 is transversely connected at the midpoint of a connecting rod 414, the eccentric wheel self-tightening clamp 408 is connected at two ends of the connecting rod 414 downwards, when a grabbing mechanism is aligned with a ball valve handle 40, the piston rod of the pre-tightening cylinder 406 is in an extending state at an initial position, then an electric control system 200 controls the pre-tightening cylinder 406 to act, the piston rod of the pre-tightening cylinder 406 retracts to give an external force to the eccentric wheel self-tightening clamp 408, the eccentric wheel self-tightening clamp 408 pre-tightens the handle 40, 2 eccentric wheel self-tightening clamps 408 are symmetrically clamped at two ends of the handle 40, a first telescopic cylinder 405 drives the grabbing mechanism to pull the handle 40 upwards, and the restoring force is larger as the handle 40 gives a downward restoring force to the eccentric wheel 412 when pulling, the larger the clamping force of the eccentric wheel self-tightening clamp 408 is, which is caused by the structural characteristics of the eccentric wheel self-tightening clamp 408 itself, and two parallel forces are applied upwards on two ends of the handle 40 by the 2 eccentric wheel self-tightening clamps 408, so that the situation that the gripping and the falling are caused by insufficient clamping force is not easy to occur in the upwards pulling process; the eccentric wheel mechanism 410 belongs to a boosting structure when the eccentric wheel self-tightening clamp 408 clamps, the fixed gear sheet 416 is a matching structure with the eccentric wheel 412, and the surface of the fixed gear sheet 416 is provided with a gear groove 415, so that the friction force during clamping can be increased, and the eccentric wheel is not easy to slip; and the anti-skid thread groove 415 on the circumferential outer wall of the eccentric wheel 412 can also increase the friction force between the eccentric wheel 412 and the clamped ball valve handle 40, and the anti-skid thread groove 415 on the circumferential outer wall of the eccentric wheel is matched with the thread groove 415 on the fixed thread, so that the clamping is more stable and the ball valve handle is not easy to slip. When clamping is needed, the eccentric wheel mechanism 410 is acted by the air cylinder, so that the distance between the occlusion ports is gradually reduced to bite the ball valve handle 40; when the ball valve handle needs to be loosened, the eccentric wheel mechanism 410 is reset under the action of the air cylinder, so that the distance between the occlusion ports is gradually increased, and the ball valve handle 40 is loosened; the rotation center of the eccentric wheel 412 in the eccentric wheel mechanism 410 is not at the geometric center of a circle, and the change of the rotation radius and therefore the force can be generated when the eccentric wheel 412 rotates around the rotating shaft at the rotation center; in the layout, the eccentric wheel handle 413 is positioned above, the rotation center and the rotating shaft are positioned below, the opening of the occlusion port faces downwards and can be right opposite to the handle 40 of the snap ball valve, when the piston rod of the pretension cylinder 406 extends, the eccentric wheel 412 rotates around the rotating shaft 411, the distance between the eccentric wheel 412 and the fixed toothed disc is larger and larger, namely the occlusion port is loosened; when the piston rod of the pretension cylinder 406 is retracted, the eccentric 412 rotates around the rotating shaft 411, and the distance between the eccentric 412 and the fixed blade becomes smaller and smaller, so that the function of clamping can be achieved.

In the process that the second telescopic cylinder 502 pushes the occlusion cylinder 509 to move downwards, after the O-shaped ring grabbing concave die 511 reaches the inner cavity of the ball valve, the installation position of the O-shaped ring 20 of the ball valve is punctured, so that the O-shaped ring is taken off and clamped in the O-shaped ring grabbing concave die 511; a piston rod of the meshing cylinder 509 extends out to drive the connecting rods 513 on the two sides to act, an included angle between the two connecting rods 513 is enlarged, the connecting rods 513 are attached to the grabbing blade 512, a slant thrust is given to the grabbing blade 512 at the first end of the grabbing blade 512, so that the third angle end of the grabbing blade rotates inwards around the second angle end, the hook heads 514 on the two grabbing blades 512 are close to each other, and the O-shaped ring 20 on the O-shaped ring grabbing female die 511 can be hooked; the grabbing blade 512 is of an isosceles triangle structure, which is a preferred embodiment, and may be any shape capable of achieving the function; the O-shaped ring grabbing concave die 511 needs to crush the mounting position of the ball valve O-shaped ring 20 downwards, so that the O-shaped ring grabbing concave die is not connected with the inner cavity of the ball valve, the height of the small cylinder is not very high, the small cylinder is matched with the inside of the ball valve O-shaped ring 20, the circular groove can cover and press down the whole ball valve O-shaped ring 20, the O-shaped ring 20 is located in the circular groove after falling down, the hook head 514 of the connecting rod blade hooks in the circular groove after being tightened, the ball valve O-shaped ring 20 can be hooked, the O-shaped ring 20 can not fall back into the inner cavity of the ball valve, the circumferential outer wall of the circular groove is provided with certain sharpness, and the mounting position of the circumferential direction of the O-shaped.

After the ball valve 300 to be processed is processed in the front section, the ball valve 300 to be processed is cut into 2 symmetrical semi-ball valve bodies 80, and the semi-ball valve bodies are separately grabbed by the half-body transferring and valve core blanking mechanism 7 and transferred to the traverse stepping mechanism 8 for rear-end processing.

The fifth step: and (4) discharging and recovering after the valve core 30 is grabbed. The lateral moving step mechanism 8 is responsible for carrying out rear-end processing on the semi-main body and the semi-ball valve main body 80 transferred by the valve core blanking mechanism 7, in the working process, every 2 semi-ball valve main bodies 80 form a group, and 3 groups of semi-ball valve main bodies 80 are arranged on a common ball valve processing work line 807; taking a group of half ball valve main bodies 80 as an example, in step 1, the half ball valve main bodies 80 reach the head end of a ball valve processing station line 807 (namely an operation line of 6 half ball valve operation station strokes) through a half main body transfer and valve core blanking mechanism 7, and after the half ball valve main bodies 80 are fixed on the processing station by a first three-jaw air cylinder 806, valve core blanking recovery is carried out; step 2: the traversing stepping mechanism 8 drives the semi-ball valve main body 80 to move a station along the ball valve processing station line 807, at the moment, the semi-ball valve main body 80 is matched with the inner cavity milling mechanism 9 at the corresponding position for inner cavity milling processing, so that the fixed barbs and impurities on the inner wall of the semi-ball valve main body can be scraped, and the flatness and the cleanliness of the inner wall of the recovered semi-ball valve main body 80 are kept; and 3, step 3: the transverse moving step station drives the semi-ball valve main body 80 to move a station along the ball valve processing station line 807, at the moment, the semi-ball valve main body 80 is matched with the rubber ring grabbing mechanism 10 at the corresponding position, and the rubber ring 50 remained in the semi-ball valve main body 80 is grabbed and recovered finally; and 4, step 4: the traversing stepping station drives the hemisphere valve main body 80 to move a station along the ball valve processing station line 807, at this time, the hemisphere valve main body 80 is already a very pure hemisphere valve main body 80 and can be directly recycled through the hemisphere valve main body blanking hopper 809, which is four process steps that a single group of hemisphere valve main bodies 80 can undergo in the device. In actual production, 3 groups of the half ball valve main bodies 80 are set to simultaneously carry out different process steps, for example, in an initial state, the head end of a ball valve processing tool line 807 is provided with a 1 st group of the half ball valve main bodies 80, and valve core recovery processing is carried out; the middle end of the ball valve processing tool line 807 is provided with a 2 nd group of hemispherical valve main bodies 80 which are subjected to inner cavity milling processing; the tail end of the ball valve processing tool line 807 is provided with a group 3 hemisphere valve main body 80 which is performing rubber ring grabbing processing; the 3 groups of the semi-spherical valve main bodies 80 are simultaneously subjected to corresponding processes; after the 3 groups of the semi-spherical valve main bodies 80 finish the corresponding working procedures, the traversing stepping mechanism 8 clamps and grabs the 3 groups of the semi-spherical valves at the same time, and moves a station along the ball valve processing working line 807, so that the 3 groups of the semi-spherical valves simultaneously enter the corresponding next working procedure, namely, the 1 st group of the semi-spherical valve main bodies 80 enter the middle end of the ball valve processing working line 807 and are matched with the inner cavity milling mechanism 9 at the corresponding position for inner cavity milling treatment; the 2 nd group of semi-spherical valve main bodies 80 enter the tail end of the ball valve processing work line 807, are matched with the rubber ring grabbing mechanism 10 at the corresponding position, and grab and recover the rubber rings 50 which are finally retained in the semi-spherical valve main bodies 80; the group 3 hemisphere valve main body 80 exceeds the ball valve processing work line 807, and since the group 3 hemisphere valve main body 80 has completed all the disassembling process at this time, the traversing stepping mechanism 8 loosens the group 3 hemisphere valve main body, and the group 3 hemisphere valve main body 80 falls into the hemisphere valve main body blanking hopper 809 for collection and recovery; after the stepping action is completed, the traversing stepping mechanism 8 does not grab any hemisphere valve main body 80, directly moves back to a station to reach the initial position, and prepares for next grabbing movement, so that the steps are repeated, the hemisphere valve main body 80 moves along the ball valve processing station line 807 in a stepping mode and multi-ball valve processing is realized, and the automation degree and the operation efficiency of disassembling and recycling the hemisphere valve main body 80 are improved.
