Description

Technical Field

[0001] The utility model relates to the technical field of lost foam casting, in particular to a device for cleaning burrs on the surface of castings. Background Art

[0002] Lost foam casting is a new casting method in which paraffin or foam models with similar size and shape to the casting are bonded together into a model cluster, coated with refractory paint and dried, buried in dry quartz sand for vibration molding, and poured under negative pressure to vaporize the model. Liquid metal occupies the model position and forms a casting after solidification and cooling. After the lost foam casting is completed, it must be polished to meet the requirements of casting surface accuracy.

[0003] After searching, the Chinese patent publication number is CN217045765U, which discloses a burr cleaning device for the surface of metal castings. When the grinding wheel is grinding the casting, the driving motor will drive the lifting screw to rotate through the rotating shaft, and the movable block on the surface of the lifting screw will also drive the fan to do lifting and lowering movements, so that the wind blown out by the fan can blow the debris generated by grinding and deburring to the side away from itself, and then the debris will fall through the collection trough. When the driven wheel rotates, it will drive the negative pressure fan to rotate to generate negative pressure suction, so that the debris in the collection net bag can be adsorbed.

[0004] However, lost foam castings are usually irregular in shape. The prior art is basically capable of grinding and deburring castings with simple shapes, but some positions on irregularly shaped castings are difficult to grind and still require manual grinding and deburring, which has low adaptability.

A ball seat 603 is welded on the rotating shaft 602, and an arc-shaped slide groove 604 is provided along the spherical surface of the top of the ball seat 603. The ball seat 603 is driven by the first motor 601 to rotate forward and backward, and the ball seat 603 drives the lateral turning mechanism 7 to turn forward and backward, thereby turning the fixing mechanism 8 forward and backward, and finally turning the casting forward and backward;

[0026] The transverse flip mechanism 7 includes a motor seat 701, which is welded to the front side of the ball seat 603. The top of the motor seat 701 is connected to a second motor 702 by bolts. The output shaft of the second motor 702 is fixedly connected to a connecting rod 703. The top of the connecting rod 703 is connected to a slider 704 by screws. The slider 704 is slidably connected in the arc-shaped slide groove 604. The connecting rod 703 is driven by the second motor 702 to swing left and right. The connecting rod 703 drives the slider 704 to slide and flip left and right in the arc-shaped slide groove 604. The slider 704 drives the fixing mechanism 8 to flip left and right, so that the casting flips left and right. The adjustment of various angles of the casting is achieved through the cooperation of the longitudinal flip mechanism 6 and the transverse flip mechanism 7 to ensure that the casting can be fully polished.

The ball seat 603 drives the lateral flipping mechanism 7 to flip forward and backward, and the lateral flipping mechanism 7 drives the fixing mechanism 8 and the casting to flip forward and backward. The second motor 702 drives the connecting rod 703 to swing left and right, and the connecting rod 703 drives the slider 704 to slide left and right in the arc-shaped slide groove 604. The arc-shaped slide groove 604 drives the fixing mechanism 8 and the casting to flip left and right, thereby adjusting the inclination of the casting. The rotating motor 801 drives the placing plate 802 to rotate, adjusts the posture of the casting, and makes the position of the casting that needs to be polished and deburred be located at the top.
