Detailed Description

The invention is further illustrated by the following examples and figures.

The automatic annular pouring line comprises a rotary table, a loading device and a discharging device, wherein the loading device is arranged on one side of the rotary table and used for placing a sand box on the rotary table, and the loading device comprises six-axis robots and clamping jaws arranged on the six-axis robots.

As shown in the figure: the turntable comprises a base 1, a driving device 2, a disc 4 and a pouring station, wherein the disc 4 is rotatably arranged on the base 1, and the driving device 2 is arranged on the base 1 and used for driving the disc 4 to rotate. A plurality of pouring stations are arranged on the disc 4, a sand box loading station is close to the loading device, and a sand box unloading station is close to the unloading device. The casting station comprises a clamping oil cylinder 5, a movable template 6 and a fixed template 7 which are arranged oppositely, the movable template 6 is installed at the end part of a piston rod of the clamping oil cylinder 5 through a universal joint, a sand box is placed between the movable template 6 and the fixed template 7, and the distance between the movable template 6 and the fixed template 7 can be adjusted when the clamping oil cylinder 5 works, so that the sand box is clamped or loosened.

The discharging device comprises a frame 8, a discharging oil cylinder 9 and a discharging plate 11. The discharging oil cylinder 9 is mounted on the frame 8 through an oil cylinder support, the piston rod end of the discharging oil cylinder 9 faces the rotary table, the blanking plate 11 is connected with the piston rod of the discharging oil cylinder 9 through a connecting rod 10, the blanking plate 11 can penetrate into the inner sides of the movable template 6 and the fixed template 7, and the sand box between the movable template 6 and the fixed template 7 is pulled out of the rotary table under the action of the discharging oil cylinder 9. A conveyor 12 is arranged below the frame 8, and the conveyor 12 can be any commercially available scraper conveyor for horizontal conveying and is used for conveying away the sand boxes and castings unloaded by the unloading device.

Specifically, the disc 4 is rotatably mounted on the base 1 by using the slewing bearing 3, and can simultaneously bear larger axial and radial loads and overturning moments, so that the selection requirement of the disc 4 is met. The number of pouring stations is 8, and the pouring stations are uniformly distributed along the circumference of the disc 4. The driving device 2 is a servo speed reduction motor.
