Description

Technical Field

[0001] This utility model relates to the field of metal processing and manufacturing technology, specifically to a metal casting cleaning device. Background Technology

[0002] Metal castings are shaped metal objects obtained through various casting methods. This involves pouring molten metal into a pre-prepared mold using methods such as pouring, injection, suction, or other casting techniques. After cooling and subsequent processing such as grinding, the resulting object possesses a specific shape, size, and properties. Castings can be classified in several ways: according to the metal material used, they are divided into cast steel, cast iron, cast copper, cast aluminum, cast magnesium, cast zinc, and cast titanium, among others. Each type of casting can be further subdivided according to its chemical composition or metallographic structure. For example, cast iron can be classified into gray cast iron, ductile iron, vermicular graphite cast iron, malleable cast iron, and alloy cast iron, among others. Based on the molding method, castings can be classified into ordinary sand castings, metal mold castings, die castings, centrifugal castings, continuous castings, investment castings, ceramic mold castings, electroslag remelting castings, and bimetallic castings, among others. Ordinary sand castings are the most widely used, accounting for about 80% of all casting production. Castings of non-ferrous metals such as aluminum, magnesium, and zinc are mostly die castings.

[0003] When processing metal castings, ultrasonic cleaning machines are typically used to clean their outer surfaces. However, existing technologies lack a reversing mechanism. Because the ultrasonic generator and transducer of the cleaning machine are fixed in position, cleaning dead zones may appear on the outer surface of the metal casting away from the sound source, resulting in poor cleaning performance. To address the lack of a reversing mechanism in existing technologies, this application proposes a new solution by setting up a support frame and a positioning cage. This allows the positioning cage to rotate around a horizontal axis inside the support frame, while the support frame drives the positioning cage to rotate around a vertical axis. This ensures that every surface of the metal casting inside the positioning cage corresponds to the direction of ultrasonic wave generation, thereby reducing cleaning dead zones and improving cleaning efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

Furthermore, for the sake of simplicity, some conventional structures and components will be shown in a simple schematic manner in the illustrations.

[0017] Please see Figure 1 , 23, 4, 5, This utility model discloses a metal casting cleaning device, comprising a cleaning tank 1, an internal support frame 2, a rotatably connected positioning shell 3, a fixedly connected positioning cage 4, two first pulleys 5 and two second pulleys 6 rotatably connected to the outer surface of the support frame 2, a transmission rod 7 fixedly connected between the two second pulleys 6, a first gear 8 fixedly connected to the middle section of the transmission rod 7, a second gear 9 rotatably connected to the internal support frame 2, the first gear 8 meshing with the second gear 9, a drive gear 10 and a driving gear 11 rotatably connected to the lower surface of the support frame 2, a gear ring frame 12 fixedly installed on the inner bottom wall of the cleaning tank 1, the driving gear 11 meshing with the inner side of the gear ring frame 12, and an ultrasonic generator, transducer, and other components installed inside the cleaning tank 1, with their switching and power controlled by a PLC controller. All of these are already... According to conventional technology, a motor is fixedly installed inside the cleaning tank 1. The output end of the motor is fixedly connected to the drive gear 11. The connection between the output end of the motor and the inner wall of the cleaning tank 1, and the connection between the transmission rod 7 and the support frame 2, are all mechanically sealed. The inside of the cleaning tank 1 is used to add cleaning fluid. In this application, the components that need to be immersed in the cleaning fluid are all made of anti-corrosion materials, and their outer surfaces are all rust-proofed. The outer surface of the positioning shell 3 is fixedly connected to two first pulleys 5. The first pulleys 5 and the second pulleys 6 are symmetrically installed. The outer surfaces of the first pulleys 5 and the second pulleys 6 are both provided with teeth. The two are connected by a synchronous toothed belt. The first gear 8 and the second gear 9 are both bevel gears. The driving gear 10 is fixedly connected to the second gear 9. The driving gear 10 is rotatably connected to the gear ring frame 12. The first pulley 5 is used to drive the positioning shell 3 and the positioning cage 4 to rotate, and the drive gear 11 is used to drive the support frame 2 to rotate.

[0018] A reversing gear 13 is rotatably connected to the lower surface of the support frame 2. The reversing gear 13 meshes with the driving gear 10 and the drive gear 11. The reversing gear 13 is used to drive the drive gear 11 to rotate and adjust the direction of the drive gear 11, so that the drive gear 11 can drive the support frame 2 to rotate, and so that the support frame 2 and the second gear 9 can achieve coaxial reversal.

[0019] The positioning cage 4 is equipped with positioning rods 14 arranged at equal angles inside. Each positioning rod 14 has four support rods 15 rotatably connected to its outer surface. The support rods 15 are used to support the positioning rods 14 and drive the positioning rods 14 to move closer to or away from the axis of the positioning cage 4, thereby clamping and fixing the metal castings inside the positioning cage 4.

[0020] Each positioning cage 4 has a slide rail assembly 16 arranged at equal angles fixedly connected inside. Each slide rail assembly 16 has two sliders 17 slidably connected inside. The outer surface of each slider 17 is rotatably connected to the other end of the corresponding support rod 15. The slide rail assembly 16 supports the positioning rod 14 through the sliders 17 and the support rods 15.

[0021] Each slide rail assembly 16 has a drive rod 18 rotatably connected inside. The outer surface of each drive rod 18 is threadedly connected to the corresponding slider 17. The outer surface of the drive rod 18 has a bidirectional thread. The drive rod 18 rotates to drive the slider 17 to slide, so that the two corresponding sliders 17 can move closer to each other or further away from each other.

[0022] Each drive rod 18 is fixedly connected to an internal gear 19 in the middle section. An external gear ring 20 is rotatably connected inside the positioning housing 3. Each internal gear 19 meshes with the inner side of the external gear ring 20. The external gear ring 20 drives multiple drive rods 18 to rotate simultaneously through the internal gears 19, thereby enabling multiple positioning rods 14 to move simultaneously.

[0023] An external gear 21 is rotatably connected inside the positioning housing 3, and a rotating wheel is rotatably connected to the outer surface of the positioning housing 3. The external gear 21 is fixedly connected to the rotating wheel, and the external gear 21 meshes with the external gear 20. The rotating wheel drives the external gear ring 20 to rotate through the external gear ring 21.

[0024] The implementation principle is as follows: The metal casting to be cleaned is placed inside the positioning cage 4. The rotating wheel rotates the external gear 21, which in turn drives the external gear ring 20 to rotate. The external gear ring 20 drives the internal gear 19 to rotate, which in turn drives the drive rod 18 to rotate. The drive rod 18 then drives the slider 17 to slide. The slider 17, through the support rod 15, moves the positioning rod 14, thus clamping the metal casting. An external power supply is connected, and an appropriate amount of cleaning fluid is added to the cleaning tank 1 to completely submerge the metal casting. The ultrasonic generator and transducer are then activated to clean the metal casting. The motor is started, and its output drives the drive gear 10 to rotate. The second gear 9 is driven to rotate, which in turn drives the first gear 8 to rotate. The first gear 8 drives the transmission rod 7 to rotate, which in turn drives the second pulley 6 to rotate. The second pulley 6 drives the first pulley 5 to rotate via a synchronous toothed belt. The first pulley 5 drives the positioning cage 4 to rotate around the axis of the first pulley 5 via the positioning shell 3. At the same time, the drive gear 10 drives the drive gear 11 to rotate via the reversing gear 13. The drive gear 11 drives the support frame 2 to rotate around the axis of the drive gear 10, and the direction of rotation is opposite to that of the drive gear 10. This allows each side of the metal casting inside the positioning cage 4 to correspond to the direction of ultrasonic wave generation, thereby improving cleaning efficiency.
