Technical Field

[0001] This utility model relates to the field of casting production technology, specifically to an automatic casting placement device. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. That is, smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, it is processed by subsequent means such as grinding to obtain an object with a certain shape, size and performance. After the production of castings is completed, they are usually moved to a designated area by conveyor belt, saving the time of manual transportation one by one and effectively improving transportation efficiency.

[0003] However, in actual use, since the castings are randomly placed on the conveyor belt, they are quite messy when they are transported to the designated location, requiring manual sorting, which greatly reduces the factory's turnover efficiency.

[0004] Therefore, it is necessary to invent an automatic casting placement device to solve the above problems. Utility Model Content

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] This utility model provides, for example Figures 1 to 3An automatic casting placement device is shown, comprising a transmission frame 1, a transmission screw 11 rotatably connected between the inner walls of the left and right sides of the transmission frame 1, a bidirectional motor 12 fixedly installed at the right end of the transmission frame 1, the output end of the bidirectional motor 12 fixedly connected to the right end of the transmission screw 11, positioning plates 13 fixedly connected to the front and rear surfaces of the transmission frame 1, and a placement module provided on the lower side of the transmission frame 1. The placement module includes a positioning frame 2, a rotary cylinder 21, a transmission gear 23, a guide rod 24, a transmission rack 26, a connecting frame 3, a connecting rod 31, positioning rollers 32, positioning blocks 33, clamping plates 4, and clamping blocks 44. The connecting frame 3 is fixedly connected to the upper surface of the positioning frame 2, the positioning blocks 33 are fixedly connected to the middle of the upper end of the connecting frame 3, and the positioning blocks 33 are threadedly connected to the transmission screw 11. The front and rear sides of the upper end of the connecting frame 3 are fixedly connected to the connecting rods 31, and the left and right ends of the connecting rods 31 are rotatably connected to the positioning rollers 32. The front and rear positioning rollers 32 are respectively clamped on the upper surfaces of the front and rear positioning plates 13.

[0032] During use, the output end of the bidirectional motor 12 drives the transmission screw 11. When the transmission screw 11 rotates clockwise, it drives the positioning block 33 to slide to the right. When the transmission screw 11 rotates counterclockwise, it drives the positioning block 33 to slide to the left, thereby driving the connecting frame 3 to slide left and right. During the sliding process of the connecting frame 3, the positioning roller 32 rolls left and right on the surface of the positioning plate 13, which effectively improves the smoothness of the movement of the connecting frame 3, reduces the wear of the equipment, and increases the service life of the equipment. During the left and right sliding process of the connecting frame 3, it drives the positioning frame 2 to move left and right. The positioning frame 2 drives the castings fixed by the clamping plate 4 and the clamping block 44 to move, and accurately places the castings in sequence.

[0033] See Figures 3 to 6A rotary cylinder 21 is fixedly installed at the center of the upper surface of the positioning frame 2. A transmission gear 23 is rotatably connected to the center of the inner side of the positioning frame 2. The output end of the rotary cylinder 21 is fixedly connected to the upper end of the transmission gear 23. Four sets of guide rods 24 are provided on the side of the transmission gear 23. The front and rear sets of guide rods 24 are located above the left and right sets of guide rods 24. Guide grooves 25 are opened on the surface of the guide rods 24 near the transmission gear 23. A transmission rack 26 is provided on the surface of the four sets of guide rods 24 near the transmission gear 23. The transmission rack 26 meshes with the transmission gear 23. A guide block 27 is fixedly connected to the surface of the transmission rack 26 away from the transmission gear 23. The guide block 27 and the guide groove 25 are connected to each other. The positioning frame 2 has four sets of limiting grooves 22 on its lower surface. Each of the four sets of limiting grooves 22 is slidably connected to a clamping plate 4. The upper end of the clamping plate 4 is fixedly connected to a connecting block 28. The connecting block 28 is fixedly connected to the end of the transmission rack 26 away from the transmission gear 23. Each of the four sets of clamping plates 4 is fixedly connected to a limiting sleeve 41. The limiting sleeve 41 is slidably connected to a limiting rod 42. Each of the four sets of limiting rods 42 is fixedly connected to a limiting block 43 on its outer side. Each of the two upper sets of limiting rods 42 and the two lower sets of limiting rods 42 is fixedly connected to a clamping block 44 on its inner side. A limiting spring 45 is sleeved on the surface of the limiting rod 42. The two ends of the limiting spring 45 abut against the surfaces of the clamping plate 4 and the clamping block 44, respectively.

[0034] Specifically, during the process of fixing the casting, the output end of the rotary cylinder 21 drives the transmission gear 23 to rotate. The transmission gear 23 drives the four sets of transmission racks 26 to slide. The front and rear sets of transmission racks 26 and the left and right sets of transmission racks 26 slide in opposite directions, thereby driving the four sets of clamping plates 4 on the lower side to slide inward and move closer together. During the sliding of the transmission racks 26, the guide block 27 slides inside the guide groove 25. The guide rod 24 and the guide groove 25 limit the position of the transmission racks 26. The four sets of clamping plates 4 drive the clamping blocks 44 on their surfaces to slide inward. When the clamping block 44 touches the casting, it will push it inward. All four sets of clamping blocks 44 on the surface of the clamping plate 4 are in contact with the surface of the casting. As the rotary cylinder 21 continues to rotate, the four sets of clamping plates 4, together with the clamping blocks 44 on their surfaces, clamp and fix the casting. During the clamping process of the clamping block 44, it will drive the limiting rod 42 to slide outward inside the limiting sleeve 41, and squeeze the limiting spring 45. This effectively prevents the clamping block 44 from clamping the surface of the casting too tightly, avoids damage to the surface of the casting, and can be used for irregular castings, thus improving the adaptability.

[0035] The working principle of this utility model is as follows: The casting is positioned and clamped by the cooperation of the rotary cylinder 21, the transmission gear 23, the transmission rack 26, the clamping plate 4 and the clamping block 44. At this time, the bidirectional motor 12 drives the transmission screw 11 to rotate, moving and placing the casting, reducing manual intervention, improving the automation level of the equipment, and effectively improving the casting conveying efficiency and factory turnover efficiency.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
