[0015] The beneficial effects of the present invention are as follows: the present invention is a fully automatic butterfly valve processing production line that effectively improves the valve disc insertion accuracy and facilitates the rapid installation of the valve. The specific implementation method is as follows;

[0016] The operator first puts the valve disc between the guide rod and the thrust disc, then starts the return motor to drive the auxiliary gear to rotate the gear ring. During the rotation of the gear ring, one end of the guide rod rotates along the outer edge of the valve disc until it is stuck in both ends of the valve disc center axis. The thrust disc is pushed by the top disc spring to allow the valve disc to pass between the guide rods. Repeat this process several times to place multiple valve discs into the disc delivery barrel.

[0017] Then, the height of the lifting frame is raised, and the butterfly valve body is placed above the through-hole bearing plate by using a mechanical arm or manually, and at the same time, the through-hole on the butterfly valve body is in a straight line with the valve stem through-hole, and the lifting frame is lowered so that the lifting frame and the through-hole bearing plate clamp the butterfly valve body, and then the twisting motor is driven to rotate the twisting gear, which drives the meshing teeth on the power plate to rotate, and further drives the guide column along the divergent groove and the arc expansion groove. The guiding effect causes the guide column to push the fixed arc block to expand until the fixed arc block engages with the edge of the butterfly valve body. In order to ensure that the butterfly valve body does not collide with the fixed arc block when it is placed on the through-hole bearing plate, while the fixed arc block expands outward, the guide column gradually moves from the low position of the lifting auxiliary inclined block to the high position, thereby realizing the lifting and lowering effect on the fixed arc block.

[0018] In order to prevent the valve disc from being located below the central axis of the butterfly valve body when the chuck block is buckled, when the valve disc contacts the inner cavity of the butterfly valve body, it is constrained by the inner cavity of the butterfly valve body caused by the gradual approach, driving one end of the chuck block to adjust the relative position of the sliding pin and the support plate until the valve disc is completely located in the center of the butterfly valve body, and then the valve disc can continue to be pushed into the inner cavity of the butterfly valve body;

[0019] After that, start the 1st push plate mechanism to rise, drive the chuck block on the support plate to buckle the valve disc on the guide rod to disengage the auxiliary spring and fall into the flared groove in the chuck block. Since the flared groove is a V-shaped structure, it can buckle the bottom of the valve disc to prevent it from falling off, and continue to start the lifting rod to drive the chuck block on the sliding nail to rise. At the same time, when the pushing rack is about to engage the rotating gear, keep the distance between the bottom of the extrusion plate and the butterfly valve body and the distance between the bottom of the valve disc and the butterfly valve body relative. When the pushing rack rises, the rotating gear is driven to rotate and the movable rack is driven to descend at the same time. When the movable rack descends, it drives the guide lifting rod to resist the reset spring to push the extrusion plate closer to complete the height restriction of the valve disc; until the valve disc contacts the extrusion plate, the position of the valve disc can be determined, and the valve stem can be passed into the valve disc through the valve stem through hole to complete the valve installation; repeat the fixing process of the butterfly valve body in reverse to remove the installed valve.

[0020] The device has a simple structure. After the butterfly valve body is positioned by clamping action, the valve disc pushed into the butterfly valve body cooperates with the extrusion plate to complete the centering of the valve disc, effectively solving the problem of entry accuracy and facilitating the rapid installation of the butterfly valve. It has good stability and practicality, and is beneficial to the promotion and use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] Working principle of the present invention:

[0039] The operator first puts the valve disc 6 between the guide rod 131 and the thrust plate 15, and then starts the return motor 152 to drive the auxiliary gear 153 to rotate the gear 364 ring 13. During the rotation of the gear ring 13, one end of the guide rod 131 rotates along the outer edge of the valve disc 6 until it is stuck in the two ends of the center axis of the valve disc 6. The thrust plate 15 is pushed by the top plate spring 151 to allow the valve disc 6 to pass between the guide rods 131. Repeating this process several times can put multiple valve discs 6 into the disc delivery cylinder 11.

[0040] After that, the lifting frame 34 is raised, and the butterfly valve body 5 is placed above the through-hole supporting plate 31 by using a mechanical arm or manually, and at the same time, the through-hole on the butterfly valve body 5 is in a straight line with the valve stem through-hole 361, and then the lifting frame 34 is dropped so that the lifting frame 34 and the through-hole supporting plate 31 clamp the butterfly valve body 5, and then the twisting motor 323 is driven to rotate the twisting gear 3231, driving the meshing teeth 321 on the power disk 32 to rotate, and further driving the guide column 37 along the divergent groove 311 and the guiding effect of the arc expansion groove 322 so that the guide column 37 pushes the fixed arc block 371 to expand until the fixed arc block 371 engages with the edge of the butterfly valve body 5. In order to ensure that the butterfly valve body 5 does not collide with the fixed arc block 371 when it is placed on the through-hole supporting plate 31, while the fixed arc block 371 expands outward, the guide column 37 gradually moves from the low position of the lifting auxiliary inclined block 33 to the high position, thereby realizing the lifting and lowering effect on the fixed arc block 371.

[0041] In order to prevent the valve disc 6 from not being located below the central axis of the butterfly valve body 5 when the chuck block 223 is buckled, when the valve disc 6 contacts the inner cavity of the butterfly valve body 5, it is constrained by the inner cavity of the butterfly valve body 5 caused by the gradual approach, driving one end of the chuck block 223 to adjust the relative position of the sliding pin 221 and the support plate 22, until the valve disc 6 is completely located at the center of the butterfly valve body 5, and then the valve disc 6 can continue to be pushed into the inner cavity of the butterfly valve body 5;

[0042] Then, the lifting rod 21 is started to drive the chuck block 223 to rise, and the chuck block 223 on the support plate 22 is driven to buckle the valve disc 6 on the guide rod 131 to disengage the auxiliary spring 132 and fall into the flared groove 224 in the chuck block 223.

The lifting rod 21 is continued to be started to drive the chuck block 223 on the sliding nail 221 to rise. At the same time, when the push rack 23 is about to engage the rotating gear 364, the distance between the bottom of the extrusion plate 341 and the butterfly valve body 5 and the bottom of the valve disc 6 are maintained. Relative to the distance between the butterfly valve body 5 and the driving rack 23, when the driving rack 23 rises, the rotating gear 364 is driven to rotate and the movable rack 35 is driven to descend. When the movable rack 35 descends, the guide lifting rod 343 is driven to resist the reset spring 342 to push the extrusion plate 341 closer to complete the height restriction of the valve disc 6; until the valve disc 6 contacts the extrusion plate 341, the position of the valve disc 6 can be determined, and the valve stem 51 can be passed into the valve disc 6 through the valve stem through hole 361 to complete the valve installation; the fixing process of the butterfly valve body 5 is repeated in reverse to remove the installed valve.
