Description

Technical Field

[0001] The invention belongs to the technical field of valve manufacturing, and in particular relates to a feed lifting device for producing a ball head of a ball valve. Background Art

[0002] A ball valve is a valve whose opening and closing part (ball) is driven by the valve stem and rotates around the axis of the ball valve. It can also be used for fluid regulation and control. Ball valves are divided into pneumatic ball valves, electric ball valves, and manual ball valves according to the driving method. In China, ball valves are widely used in oil refining, long-distance pipelines, chemicals, papermaking, pharmaceuticals, water conservancy, electricity, municipal administration, steel and other industries. The production of ball valves is to install the spherical valve core of the ball valve in the valve body. At present, when assembling the ball valve, the valve core is generally installed manually.

The elastic hook and the unhooking mechanism are coordinated to form a double insurance, which ensures to the greatest extent that the hook 603 can be automatically unhooked without getting stuck.

[0040] In an optional embodiment, one end of the touch panel 604 away from the second C-shaped plate 602 is a wedge-shaped structure, and the angle between the touch panel 604 and the second C-shaped plate 602 is an acute angle.

[0041] In this embodiment: the touch plate 604 cooperates with the C-shaped plate 602, and the C-shaped plate 602 rotates around the rotating shaft until the bottom end of the touch plate 604 contacts the top of the material receiving port 10, so that the C-shaped plate 602 is tilted to a certain angle, and then the valve core 13 slides into the material receiving port 10 along the track formed between the two C-shaped plate 602 under the action of gravity.

[0042] The working principle and use process of the present invention are as follows: the motor 7 is controlled to start through the external control center, the motor 7 drives the pulley 1 8 to rotate, the pulley 2 9 is rotated through the belt transmission, and then drives the sprocket 2 3, and drives the sprocket 1 2 to rotate through the chain 4, and then drives the lifting arm 6 located on the chain 4 to move with the chain 4, so that the two lifting arms 6 constitute a lifting carrier to clamp the single workpiece valve core 13 separated by the dividing plate 12. At that time, the valve core 13 rolls to the end of the discharge port 11. With the rotation of the chain 4, the two lifting arms 6 pass through the two L-shaped plates 16 and lift the valve core 13, and at the same time, the bottom of the valve core 13 is located in the two grooves 623. With the continuous movement of the chain 4, the lifting arm 6 carrying the valve core 13 continues to move upward. Until the hook 603 is hooked on the roller 15 located at the bottom of the material receiving port 10, the C-shaped plate 602 is rotated around the rotation axis until the bottom end of the touch plate 604 contacts the top of the material receiving port 10, so that the C-shaped plate 602 is tilted to a certain angle, and then the valve core 13 slides into the material receiving port 10 along the track formed between the two C-shaped plate 602 under the action of gravity. At the same time, as the C-shaped plate 602 rotates around the rotation axis, the compression spring 1 606 is stretched. Since the tension spring 617 and the compression spring 2 611 are themselves in a stretched state, as the C-shaped plate 602 rotates, the distance between the mounting post 1 615 and the mounting post 2 616 becomes shorter, until the tension spring 617 returns to its original state, and then the compression spring 2 611 is It can retract, pull the limit block 610 to drive the guide rod 609 to move, and then drive the rack 612 to drive the gear 613 to rotate, drive the connecting plate 614 to drive the limit column 1 620 at the end of the hook 603 to slide along the limit groove 621, and at the same time, the limit column 2 622 cooperates with the U-shaped through hole 619, so that the hook 603 moves a certain distance under the limit of the limit column 2 622, and then the hook 603 can be rotated around the limit column 2 622, so as to achieve the purpose of unhooking, so that the C-shaped plate 2 602 passes over the material receiving port 10, and then the compression spring 1 606 retracts, driving the C-shaped plate 2 602 to reset, so as to continuously transport the valve core 13 from the discharge port 11 to the material receiving port 10, complete the lifting operation of the valve core component during the ball valve assembly process, thereby improving the working efficiency and allowing the device to work continuously.
