Description

Technical Field

[0001] This application relates to the field of metal casting grinding, and more particularly to a metal casting grinding apparatus. Background Technology

[0002] Metal castings are metal parts formed by pouring molten metal into a mold, cooling and solidifying it to form the desired shape. Casting is an ancient and widely used manufacturing process, mainly used to produce parts with complex shapes or high precision requirements. When metal castings are removed from the mold, their surfaces may have flash, burrs and unevenness. In order to improve the smoothness of the outer surface of the casting, the casting is usually polished.

[0003] The surface of castings is generally polished by a grinding machine. During the polishing process, a certain amount of metal powder is generated. This powder will be scattered into the surrounding environment along the grinding machine, which may be inhaled and affect the health of the operators. In addition, the dust splashed up can also obstruct the view, making it difficult for people to observe the polishing of the castings, thus affecting the overall processing efficiency of the castings.

[0004] Regarding the aforementioned technologies, the inventors believe that metal castings suffer from the defect of scattering metal powder during grinding. Therefore, they have proposed a metal casting grinding device to solve the above problems. Utility Model Content

[0005] To address the problem of metal powder scattering during the grinding of metal castings, this application provides a metal casting grinding device.

[0006] The metal casting grinding device provided in this application adopts the following technical solution:

[0007] A metal casting grinding device includes a grinding machine. A drive shaft is installed at the output end of the bottom surface of the grinding machine. An abrasive wheel is installed at the bottom end of the drive shaft. A protective cover is fitted on one side of the outer surface of the drive shaft. A drive motor is installed on one side of the top of the protective cover. A support shaft is installed inside the protective cover, extending from the output end of the drive motor at the bottom surface. A spiral conveyor disc is welded to the outer surface of the support shaft. A material conveying pipe is fixedly installed on the top of one side of the outer surface of the protective cover near the drive motor. A collection tank is provided below the material conveying pipe. A fixed pipe opening is fixedly installed on the upper surface of the collection tank. A limiting sleeve is fitted on the outer surface of the fixed pipe opening. A reset support mechanism is also provided inside the protective cover for supporting the movement of the grinding machine.

[0008] Preferably, the reset support mechanism includes a limiting tube, which is fixedly installed at the top of the inner wall of the protective cover near the outer surface of the drive shaft. A limiting plate is welded inside the limiting tube on one side of the outer surface of the drive shaft, and a spring is sleeved on the outer surface of the drive shaft between the limiting plate and the limiting tube.

[0009] Preferably, the outer surface of the protective cover is welded with elastic clamping plates in parallel near the lower part of the conveying pipe, and the collection tank is located inside the elastic clamping plates, with the elastic clamping plates and the collection tank engaging with each other.

[0010] Preferably, the bottom of the outer surface of the conveying pipe is provided with an external thread, and one side of the inner wall of the limiting sleeve is provided with an internal thread, and the limiting sleeve is threadedly connected to the bottom of the outer surface of the conveying pipe.

[0011] Preferably, the outer diameters of the limiting plate and the spring are both smaller than the inner diameter of the limiting tube, the outer diameter of the limiting plate is larger than the inner diameter of the openings at the upper and lower ends of the limiting tube, and the limiting tube and the limiting plate are coupled to each other.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] By placing a protective cover over the outer surface of the casting, an abrasive wheel grinds the surface, causing splashed metal powder to accumulate. A rotating spiral conveyor then transports the powder upwards, where it falls into a collection tank along a conveying pipe. Compared to existing technologies, this solution facilitates the collection of large amounts of metal powder accumulated in the protective cover, reduces the scattering of metal powder, solves the problem of metal powder dust spreading in the surrounding environment, and improves the convenience of grinding castings.

Detailed Implementation

[0020] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0021] This application discloses a metal casting grinding apparatus. (Refer to...) Figures 1-5 A metal casting grinding device includes a grinding machine 1, a drive shaft 2 mounted on the output end of the bottom surface of the grinding machine 1, an abrasive wheel 3 mounted on the bottom end of the drive shaft 2, a protective cover 4 sleeved on one side of the outer surface of the drive shaft 2, a drive motor 5 mounted on one side of the top of the protective cover 4, a support shaft 6 extending from the output end of the bottom surface of the drive motor 5 into the interior of the protective cover 4, a spiral conveyor disc 7 welded to the outer surface of the support shaft 6, a conveying pipe 8 fixedly mounted on the top side of one side of the outer surface of the protective cover 4 near the drive motor 5, and a collection tank 10 located below the conveying pipe 8. A fixed pipe port 11 is fixedly installed on the upper surface of the collection tank 10. A limiting sleeve 12 is fitted on the outer surface of the fixed pipe port 11. An external thread is opened at the bottom of the outer surface of the conveying pipe 8. An internal thread is opened on one side of the inner wall of the limiting sleeve 12. The limiting sleeve 12 is threadedly connected to the bottom of the outer surface of the conveying pipe 8. An elastic clamping plate 9 is welded in parallel on the outer surface of the protective cover 4 near the lower part of the conveying pipe 8. The collection tank 10 is located inside the elastic clamping plate 9. The elastic clamping plate 9 and the collection tank 10 are locked together. A reset support mechanism is also provided inside the protective cover 4 for moving support of the grinding machine 1.

[0022] By placing the protective cover 4 over the outer surface of the casting, the grinding machine 1 is started to drive the abrasive wheel 3 to rotate, thereby grinding the upper surface of the casting. At the same time, the protective cover 4 blocks the metal powder splashed during grinding, causing the splashed metal powder to accumulate on the upper surface of the casting. The drive motor 5 is started to drive the support shaft 6 and the spiral conveyor disc 7 to rotate, causing the rotating spiral conveyor disc 7 to convey the powder upward. The metal powder at the top of the spiral conveyor disc 7 is poured into the conveying pipe 8. The collection tank 10 is clamped and installed in the elastic clamping plate 9, causing the rotation limit sleeve 12 to move upward along the outer surface of the fixed pipe opening 11, so that the limit sleeve 12 is threadedly connected to the outer surface of the conveying pipe 8, thereby connecting the conveying pipe 8 and the fixed pipe opening 11 to each other, and causing the metal powder to fall along the conveying pipe 8 into the collection tank 10 for collection, demonstrating the overall collection effect of metal powder in the protective cover 4.

[0023] Reference Figure 4 and Figure 5The reset support mechanism includes a limiting tube 13, which is fixedly installed on the top of the inner wall of the protective cover 4 near the outer surface of the drive shaft 2. A limiting plate 14 is welded inside the limiting tube 13 on one side of the outer surface of the drive shaft 2. A spring 15 is sleeved between the limiting plate 14 and the limiting tube 13 on the outer surface of the drive shaft 2. The outer diameters of the limiting plate 14 and the spring 15 are both smaller than the inner diameter of the limiting tube 13. The outer diameter of the limiting plate 14 is larger than the inner diameter of the openings at the upper and lower ends of the limiting tube 13. The limiting tube 13 and the limiting plate 14 are coupled to each other.

[0024] By pressing the grinding machine 1, the drive shaft 2 moves downward along the inside of the limiting tube 13, causing the limiting plate 14 to move downward and compress the spring 15. This causes the abrasive wheel 3 to act on the outer surface of the casting for grinding. When grinding is canceled, the grinding machine 1 and the abrasive wheel 3 move upward under the reset action of the spring 15, causing the abrasive wheel 3 to separate from the casting. This demonstrates the reset support effect of the limiting tube 13 on the abrasive wheel 3.

[0025] The implementation principle of a metal casting grinding device according to an embodiment of this application is as follows: By covering the outer surface of the casting with a protective cover 4, the grinding machine 1 is started to drive the abrasive wheel 3 to rotate. Pressing the grinding machine 1 moves the drive shaft 2 downward along the inside of the limiting tube 13, causing the limiting plate 14 to move downward and compress the spring 15, thereby causing the abrasive wheel 3 to act on the outer surface of the casting for grinding. At the same time, the protective cover 4 blocks the metal powder splashed during grinding, causing the splashed metal powder to accumulate on the upper surface of the casting. The drive motor 5 is started to drive the support shaft 6 and the spiral conveyor 7 to rotate, causing the rotating spiral conveyor 7 to convey the powder upward, so that the metal powder at the top of the spiral conveyor 7 is poured into the conveying pipe 8, and the collection tank 10 is clamped. In the elastic clamping plate 9, the fixed pipe opening 11 is aligned with the bottom surface of the conveying pipe 8. The rotating limiting sleeve 12 moves upward along the outer surface of the fixed pipe opening 11, so that the limiting sleeve 12 is threadedly connected to the outer surface of the conveying pipe 8, thereby connecting the conveying pipe 8 and the fixed pipe opening 11 to each other, and allowing the metal powder to fall into the collection tank 10 along the conveying pipe 8 for collection. The input terminals of the power supply of the grinding machine 1 and the drive motor 5 are electrically connected to the output terminal of the external power supply. Compared with the prior art, this solution has the effect of facilitating the collection of a large amount of metal powder accumulated in the protective cover 4, reducing the effect of metal powder scattering and splashing, solving the problem of metal powder dust scattering in the surrounding environment, and improving the convenience of people grinding castings.
