[0020] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0021] like Figures 1-5As shown, this utility model provides a technical solution: a precise quantitative pouring device for molten metal in casting, including a frame 1, a servo motor 4 installed on one side of the frame 1, a container 5 rotatably connected to the bottom of the frame 1, a through groove 6 opened on one side of the container 5, a cleaning device 2 installed on one side of the frame 1, the cleaning device 2 including an electric push rod 21, the electric push rod 21 installed on one side of the frame 1, a support rod 22 installed on the output rod of the electric push rod 21, a drive motor 23 installed at the top of the support rod 22, a shaft 24 installed at the output end of the drive motor 23 via a coupling, and a disc 25 installed at the bottom end of the shaft 24 via a convenient device 3. Several wire brushes 26 are fixedly connected to the outer surface of the disc 25. When using the quantitative pouring device, one side of the top of the frame 1 is mounted on the robotic arm. The robotic arm controls the movement of the frame 1, causing the container 5 at the bottom of the frame 1 to enter the liquid pool containing the casting molten metal. Then, the servo motor 4 operates to control the container 5 to rotate at a certain angle, causing the container 5 to tilt towards the direction where the through groove 6 is provided. If the liquid level exceeds the through groove 6 on one side of the container 5 after the molten metal enters the container 5, it will leak out from the inside of the through groove 6, so that the container 5 only contains a certain amount of molten metal. Then, the robotic arm controls the frame 1 to move to the casting mold. The servo motor 4 controls the container 5 to rotate and tilt away from the channel 6, causing the molten metal inside the container 5 to pour out into the casting mold. After the molten metal is poured out, the electric push rod 21 can be operated to retract the control rod 22 and lower the height, allowing the wire brush 26 at the bottom of the shaft 24 to enter the container 5. Then, the servo motor 4 drives the shaft 24 to rotate, and the wire brush 26 on the outer surface of the disc 25 at the bottom of the shaft 24 cleans the inner wall of the container 5, scraping off as much of the molten metal residue adhering to the inner wall of the container 5 as possible. After a period of time, the operation of the drive motor 23 is stopped, and the electric push rod 21 is operated to extend the control rod 22. 2. The disc 25 is raised away from the inside of the container 5. Then, the servo motor 4 is operated to control the container 5 to tilt and pour out the scraped residue. By setting up the cleaning device 2, when using the quantitative pouring device, after the molten metal inside the container 5 is poured out, the electric push rod 21 can be operated to adjust the position of the disc 25 so that the disc 25 enters the inside of the container 5. Then, the drive motor 23 is operated to control the shaft 24 and the disc 25 to rotate. The wire brush 26 on the outer surface of the disc 25 scrapes off the residual layer of molten metal adhering to the inner wall of the container 5, so as to avoid the molten metal remaining inside the container 5 from mixing with the subsequent molten metal and affecting the pouring effect of the molten metal.
[0022] A positioning rod 27 is fixedly connected to one side of the frame rod 22. The outer surface of the shaft rod 24 rotates on the inner wall of the positioning rod 27. When the drive motor 23 drives the shaft rod 24 to rotate, the outer surface of the shaft rod 24 will rotate on the inner wall of the positioning rod 27. The positioning rod 27 can further limit the angle between the shaft rod 24 and the frame rod 22, and minimize the deviation of the shaft rod 24 during rotation. A support rod 28 is fixedly connected to one side of the output rod of the electric push rod 21. The end of the support rod 28 away from the output rod of the electric push rod 21 is fixedly connected to the bottom end of the frame rod 22. By setting the support rod 28, the frame rod 22 can be adjusted. The connection between rod 22 and the output rod of electric push rod 21 is reinforced to improve the overall structural stability of cleaning device 2. Several fan blades 29 are fixedly connected to the outer surface of shaft 24. The fan blades 29 are distributed in a circle on the outer surface of shaft 24 and are located above disk 25. When the shaft 24 is rotated by drive motor 23 to drive disk 25 to rotate and clean the inside of container 5, the fan blades 29 on the outer surface of shaft 24 will rotate at the same time. The rotation of fan blades 29 generates wind to further blow the residue on the channel 6 and the inner wall of container 5 away from the inside of container 5, thereby improving the cleaning effect of cleaning device 2.
[0023] The convenient device 3 includes a cylinder 31, the bottom end of which is fixedly connected to the top end of a disc 25. A groove 32 is formed on one side of the inner wall of the cylinder 31, and a rectangular groove 33 is formed on one side of the bottom end of the shaft 24. A locking block 35 is slidably connected to the inner wall of the rectangular groove 33. A spring 34 is provided on one side of the locking block 35, and both ends of the spring 34 are fixedly connected to one side of the locking block 35 and one side of the inner wall of the rectangular groove 33, respectively. When installing the disc 25 and the wire brush 26, the locking block 35 is pressed on one side of the shaft 24 to retract into the rectangular groove 33 and compress the spring 34. Then, the cylinder 31 is aligned with the bottom end of the shaft 24 and placed upwards onto the outer surface of the shaft 24. The cylinder 31 is then pushed to slide upwards on the outer surface of the shaft 24. When the top of the disc 25 contacts the bottom of the shaft 24, the compressed spring 34 inside the rectangular groove 33 returns to its original state and pushes the locking block 35 outward, locking the locking block 35 into the groove 32 on one side of the inner wall of the cylinder 31. The cylinder 31 and the disc 25 are installed at the bottom of the shaft 24. A slanted groove 36 is opened on one side of the top of the locking block 35. The slanted groove 36 is located on the side of the top of the locking block 35 away from the spring 34. When it is necessary to remove the cylinder 31 and the disc 25, press the cylinder 31 downward so that the top of the inner wall of the groove 32 abuts against the slanted groove 36 at the top of the locking block 35, push the locking block 35 into the rectangular groove 33, and then pull the cylinder 31 away from the outer surface of the shaft 24 to remove the cylinder 31 and the disc 25. The wire brush 26 can then be cleaned and replaced.
[0024] The working principle of this utility model is as follows: When using the quantitative pouring device, press the locking block 35 on one side of the shaft 24 to make the locking block 35 retract into the rectangular groove 33 and compress the spring 34. Then, align the cylinder 31 with the bottom end of the shaft 24 and put the cylinder 31 upward on the outer surface of the shaft 24. Push the cylinder 31 to move so that the cylinder 31 slides upward on the outer surface of the shaft 24. When the top end of the disc 25 contacts the bottom end of the shaft 24, the spring 34 compressed inside the rectangular groove 33 returns to its original state and pushes the locking block 35 outward, locking the locking block 35 into the locking groove 32 on one side of the inner wall of the cylinder 31. 1. The disc 25 is installed at the bottom of the shaft 24. Then, one side of the top of the frame 1 is mounted on the robotic arm. The robotic arm controls the movement of the frame 1, causing the container 5 at the bottom of the frame 1 to enter the pool containing molten metal. Then, the servo motor 4 operates to control the container 5 to rotate at a certain angle, causing the container 5 to tilt towards the direction where the through groove 6 is provided. After the molten metal enters the container 5, if the liquid level exceeds the through groove 6 on one side of the container 5, it will leak out from the inside of the through groove 6, so that the container 5 only contains a certain amount of molten metal. Then, the robotic arm controls the frame 1 to move to the casting mold, and the operation begins. Servo motor 4 controls the container 5 to rotate and tilt away from the channel 6, causing the molten metal inside the container 5 to pour out into the casting mold. After the molten metal is poured out, the electric push rod 21 retracts, controlling the frame rod 22 to descend, causing the wire brush 26 at the bottom of the shaft 24 to enter the container 5. Then, the servo motor 4 drives the shaft 24 to rotate, and the wire brush 26 on the outer surface of the disc 25 at the bottom of the shaft 24 cleans the inner wall of the container 5, scraping off as much of the molten metal residue adhering to the inner wall of the container 5 as possible. At the same time, the fan blades 29 on the outer surface of the shaft 24 rotate simultaneously, through... The fan blades 29 rotate to generate wind, which further blows the residue on the inner wall of the channel 6 and container 5 away from the inside of container 5. After a period of time, the operation of the drive motor 23 is stopped, and the electric push rod 21 is operated to extend the control rod 22 to raise the disc 25 away from the inside of container 5. Then, the servo motor 4 is operated to control the container 5 to tilt, pour out the scraped residue, and press the cylinder 31 downward so that the top of the inner wall of the slot 32 abuts against the inclined groove 36 at the top of the block 35, push the block 35 into the rectangular groove 33, and then pull the cylinder 31 away from the outer surface of the shaft 24 to remove the cylinder 31 and the disc 25.
