Description

Technical Field

[0001] The utility model belongs to the technical field of valve seat production, in particular to a conveying device for valve seat production. Background Art

[0002] The removable face part in the valve is used to support the fully closed position of the valve core and form a sealing pair. Generally, the valve seat diameter is the maximum flow diameter of the valve. For example, the valve seat material of the butterfly valve is very wide, and various rubber, plastic, and metal materials can be used as valve seat materials.

[0003] In the existing valve seat production process, the valve seat is mostly conveyed in a manner of clamping the valve seat with a clamping device and then conveying it to a specified position, and then the valve seat is manually removed from the clamping device, and then the valve seat is processed in the next step. Although this clamping and conveying method can accurately convey the valve seat, in actual use, removing the valve seat by manual disassembly will increase the labor intensity of the workers and greatly reduce the efficiency of valve seat production. Therefore, a conveying device for valve seat production is urgently needed to solve this problem. Utility Model Content

[0026] How it works

[0027] When the conveying device for valve seat production is used, the motor 7 in the device is first started, and the motor 7 drives the screw rod 5 fixedly connected to the end of the rotating shaft to rotate, and the screw rod 5 rotates to drive the slider 6 threaded on the rod wall to slide along the strip hole 4 horizontally opened on the cross plate 3, until the slider 6 drives the hydraulic cylinder 8 fixedly connected to the lower end and the clamping tube 9 fixedly connected to the telescopic end of the hydraulic cylinder 8 to move to the top of the valve seat to be clamped, and then the hydraulic cylinder 8 is started to drive the clamping tube 9 fixedly connected to the telescopic end of the hydraulic cylinder 8. The cylinder 9 moves downward until the clamping cylinder 9 is sleeved on the valve seat to be clamped. At this time, the outer wall of the valve seat will first contact the two arc plates 12 set on the inner wall of the clamping cylinder 9, and then the valve seat squeezes the two arc plates 12 to move toward the inner wall of the clamping cylinder 9, and at the same time drives the telescopic rod 14 fixedly connected to the outside of the arc plate 12 to shrink toward the inside of the limiting cylinder 13, and squeezes the spring 15 inside the limiting cylinder 13. At the same time, the spring 15 pushes the telescopic rod 14 to squeeze the arc plate 12 against the valve seat, and the valve seat will be sleeved to the mounting column. 10, at this time, the support airbag 11 installed on the outer wall of the mounting column 10 is started and the support airbag 11 is inflated, and the support airbag 11 is expanded to contact the inner wall of the valve seat. The support airbag 11 here is a complete inflation and deflation structure and is installed inside the mounting column 10, so it is not shown too much in the drawings. As the air pressure increases, the support airbag 11 will squeeze the inner wall of the valve seat. At this time, due to the large friction between the support airbag 11 and the inner wall of the valve seat, the valve seat can be effectively limited. At this time, the hydraulic cylinder 8 is started again, the clamping tube 9 and the valve seat are lifted by the hydraulic cylinder 8 and the motor 7 is started again, the slider 6, the clamping tube 9 and the valve seat are moved to the predetermined position by the rotation of the screw rod 5, and then the gas in the supporting airbag 11 is discharged. At this time, because the inner walls of the two arc plates 12 are equipped with multiple balls, when the inner wall of the valve seat loses the limit, the outer wall of the valve seat will slide downward and drive the balls on the inner wall of the arc plate 12 to rotate, so that the valve seat can be lowered, thereby realizing automatic transportation of the valve seat.
