Description

Technical Field

[0001] The invention relates to the technical field of mechanical casting surface treatment equipment, and more specifically to a kind of engineering machinery casting surface treatment equipment. Background Art

[0002] Engineering machinery castings are an important part of the basic parts of various heavy equipment, usually made of metal or alloy materials. In the field of engineering machinery, the fuselage, frame, boom, bucket teeth and track sprockets of equipment such as excavators, loaders, bulldozers, road rollers and concrete mixers are all common casting parts. Before leaving the factory, the castings of engineering machinery need to be painted to prevent the casting surface from rusting due to moisture in the air, and to ensure the appearance of the castings after leaving the factory. The surface treatment of engineering machinery castings requires the use of casting surface treatment equipment.

[0003] Chinese patent application number CN202022717978.3 discloses a shot blasting machine for surface strengthening of castings, including a processing main body seat, wherein transmission rollers are fixedly installed on the left and right sides of the top of the processing main body seat, and workpieces to be processed are movably installed on the top of the two transmission rollers. A collecting chute is provided on the top of the processing main body seat. By setting the collecting chute and the temporary storage trough, the steel sand and steel shots generated by the processing can be collected, and then transported to the inside of the threaded lifting pipe through a recovery conveyor belt. Finally, the operation of the transmission motor drives the threaded lifting rod to transport the steel sand and steel shots back to the inside of the top seat of the shot blasting machine.

[0004] In the above technical scheme, after the surface processing of the casting is completed, the casting is sprayed again. When spraying the surface of the casting, the small casting is usually transported to the spraying workshop first, and the personnel spray the surface of the casting with a handheld spraying device. The surface of the casting needs to be fully sprayed on multiple sides, depressions and other parts, so the workers need to hold the casting and turn it over to spray other surfaces, or adjust the angle of the spraying device to adjust the angle of the spray head, and then spray the depressions. When spraying the surface of the casting, the casting or the spraying angle is adjusted multiple times, which not only affects the speed of spraying the surface of the casting, but also affects the efficiency of spraying the surface of the casting.

At this time, the two air dryers 36 work to quickly air dry the paint on the surface of the casting body 12. The transmission chain 2 continues to transmit with the gear 6 meshing with the second tooth plate 38. The gear 6 rotates to rotate with the hook 7 and the casting body 12, so that the two air dryers 36 quickly and comprehensively dry the casting body 12. This solution brings the hook 7 and the casting body 12 into between the two box bodies 13 through the transmission chain 2. At this time, the spray head 23 sprays the top surface, bottom surface and surface of the casting body 12 at the same time.

The trapezoidal slope slide rail 18 also moves the connecting plate 19 and the slide plate 20 downward, so that the ball groove 24 moves with the movable ball 25, and then the spray head 23 moves in the movable groove 21. During the movement of the ball head 11 through the entire trapezoidal slope slide rail 18, the spray head 23 rotates up and down in the movable groove 21, and then the spray head 23 sprays the surface of the casting body 12. When the gear 6 follows the transmission chain 2 to move and meshes with the first tooth plate 27, the gear 6 rotates to rotate with the hook 7 and the casting body 12, so that the spray head 23 fully sprays the casting body 12, thereby improving the speed of spraying the surface of the casting body 12.Thus, the spraying efficiency on the surface of the casting body 12 is improved; as the transmission chain 2 continues to transmit, the hook 7 and the casting body 12 enter between the two air dryers 36, and at this time, the two air dryers 36 work to quickly dry the paint on the surface of the casting body 12, and the transmission chain 2 continues to transmit with the gear 6 meshing with the second tooth plate 38, and the gear 6 rotates with the hook 7 and the casting body 12, so that the two air dryers 36 can quickly dry the casting body 12, further improving the processing efficiency of the casting body 12.

When the arc-shaped tooth block 4 is engaged with the third tooth plate 39, the electric telescopic rod 41 extends and moves with the second spring shaft 42, so that the feeding box 43 moves to the bottom of the hook 7, and the arc-shaped tooth block 4 rotates under the action of the third tooth plate 39. The arc-shaped tooth block 4 rotates and rotates with the hook 7. At this time, the casting body 12 is separated from the hook 7 under the action of its own weight and falls into the feeding box 43. At this time, the electric telescopic rod 41 is recovered and reset with the feeding box 43. When the protrusion 45 moves and is squeezed by the protrusion 45, the feeding box 43 rotates under the action of the second spring shaft 42, so that the casting body 12 falls onto the surface of the guide plate 46, which facilitates the unloading of the casting body 12.

[0040] A guide plate 46 is fixedly connected to the end surface of the equipment body 1 . The guide plate 46 is located below one side of the feed box 43 . The guide plate 46 is used to guide the casting body 12 .

[0041] An extension plate 48 is fixedly connected to the surface of the third tooth plate 39 , and one end of the extension plate 48 is fixedly connected to the inner wall of the equipment body 1 .

[0042] The use steps of the present invention are as follows: when the surface treatment equipment for engineering machinery castings is in use, after the casting body 12 is air-dried, as the transmission chain 2 continues to servo-transmit, the arc-shaped tooth block 4, the hook 7 and the casting body 12 continue to move. When the arc-shaped tooth block 4 is meshed with the third tooth plate 39, the electric telescopic rod 41 extends and moves with the second spring shaft 42, thereby causing the feeding box 43 to move to the bottom of the hook 7. The arc-shaped tooth block 4 rotates under the action of the third tooth plate 39, and the arc-shaped tooth block 4 rotates and causes the hook 7 to rotate. At this time, the casting body 12 is separated from the hook 7 under the action of its own weight and falls into the feeding box 43. At this time, the electric telescopic rod 41 is recovered and causes the feeding box 43 to reset. When the protrusion 45 moves and is squeezed by the protrusion 45, the feeding box 43 rotates under the action of the second spring shaft 42, thereby causing the casting body 12 to fall onto the surface of the guide plate 46. A storage box is placed under the guide plate 46 in advance to store the casting body 12. The transmission chain 2 continues to servo-transmit, and when the arc-shaped tooth block 4 is disengaged from the third tooth plate 39, the arc-shaped tooth block 4 is reset under the action of the first spring shaft 3. The scheme continues to servo-transmit through the transmission chain 2, and the arc-shaped tooth block 4, the hook 7 and the casting body 12 continue to move. When the arc-shaped tooth block 4 is engaged with the third tooth plate 39, the electric telescopic rod 41 extends and moves with the second spring shaft 42, so that the feeding box 43 moves to the bottom of the hook 7, and the arc-shaped tooth block 4 rotates under the action of the third tooth plate 39. The arc-shaped tooth block 4 rotates and rotates with the hook 7. At this time, the casting body 12 is disengaged from the hook 7 under the action of its own weight and falls into the feeding box 43. At this time, the electric telescopic rod 41 is recovered and reset with the feeding box 43. When the protrusion 45 moves and is squeezed by the protrusion 45, the feeding box 43 rotates under the action of the second spring shaft 42, so that the casting body 12 falls onto the surface of the guide plate 46, which facilitates the unloading of the casting body 12.
