[0018] As Figures 1-3As shown in the figure, a surface cleaning device for V-process castings includes a support housing 1. The support housing 1 is frustum-shaped and hollow inside. One end of the support housing 1 is provided with an opening 2. It also includes a grinding head 3 and a driving assembly 4. The grinding head 3 passes through the opening 2 and is rotatably connected inside the opening 2. The driving assembly 4 is arranged inside the support housing 1 and is connected to the grinding head 3. The end of the support housing 1 far from the opening 2 is connected with a support wire-walking mechanism 5. The device is placed by supporting through the support wire-walking mechanism 5, which is convenient for workers to pick up. The driving assembly 4 drives the grinding head 3 to rotate, and the surface of the casting is polished by the grinding head 3 to achieve impurity cleaning.

[0019] As Figure 3 shown in the figure, in order to make the grinding head 3 rotate and achieve impurity cleaning on the surface of the casting, the driving assembly 4 includes a rotating motor 6, a rotating shaft 7 and a limiting plate 8. The limiting plate 8 is fixedly connected to the inner side wall of the support housing 1 near the end with the opening. One end of the rotating shaft 7 is rotatably connected to the inner end face of the support housing 1 far from the opening 2. The other end of the rotating shaft 7 passes through the limiting plate 8 and is connected to the grinding head 3. The rotating motor 6 is installed on the outer end face of the support housing 1 far from the opening 2. The output end of the rotating motor 6 is connected to the rotating shaft 7. The rotating motor 6 is externally powered. By the rotation of the rotating motor 6, the rotating shaft 7 is driven to rotate synchronously. At the same time, the internal limiting plate 8 is used to increase the stability of the rotating shaft 7, driving the grinding head 3 to rotate for grinding and cleaning.

[0020] In order to improve the observation effect on the surface of the casting during grinding, a support pad 14 is fixedly connected to the middle of the outer side wall of the support housing 1. The support pad 14 is adjacent to the air inlet 13 and is close to the end of the opening 2. An LED light strip 15 is provided at the end of the support pad 14 close to the opening 2. The LED light strip 15 faces the grinding end of the grinding head 3 and irradiates on the surface of the workpiece, which is convenient for workers to observe the flatness of the surface of the casting.

[0021] As Figures 1-3 shown in the figure, in order to blow the dust on the surface of the casting, a fan blade 9 is fixedly connected to the outer side wall of the rotating shaft 7. While the rotating motor 6 drives the rotating shaft 7 to rotate, the fan blade 9 is driven to rotate inside the support housing 1. An air inlet 13 is opened on the outer side wall of the support housing 1 far from the opening 2. The air inlets 13 are arranged at equal intervals. The rear end of the fan blade 9 extracts gas into the support housing 1 through the air inlet 13, and the gas is ejected from the corner at the opening 2 end of the support housing 1 and acts on the surface polished by the grinding head 3, simultaneously realizing the function of blowing dust.

[0022] As Figure 1 and Figure 2As shown, for the convenience of device placement and handling by workers, the support wire routing mechanism 5 includes a connecting plate 10 and a connecting pipe 11. The connecting plate 10 is arranged in an L shape. One end of the connecting plate 10 is fixedly connected to the end of the support housing 1 far from the opening 2, and the other ends of the connecting plate 10 are connected to each other. One end of the connecting pipe 11 is fixedly connected to the end of the rotating motor 6 far from the support housing 1, and the other end of the connecting pipe 11 is fixedly connected to the end where the connecting plate 10 is connected to each other. The connecting plates 10 are arranged in a pairwise symmetric cross shape. A wire routing hole 12 is opened at the center of the other ends of the connected connecting plates 10, and the wire routing hole 12 is communicated with the inside of the connecting pipe 11. The outer side walls of the connecting plates 10 that are pairwise symmetric and connected to the support housing 1 support and place the device. Inside, the connecting pipe 11 improves the connection stability, enabling workers to hold the connecting plate 10 or the connecting pipe 11 to pick up the device. At the same time, the wire routing hole 12 is communicated with the inside of the connecting pipe 11, and wires can be routed through the connecting pipe 11 to be electrically connected to the rotating motor 6 and the LED light strip 15, hiding the wire harness and reducing the obstruction of the wire harness.

[0023] During specific use, after the operator wires the device, the rotating motor 6 is driven to drive the rotating shaft 7 to rotate, and the LED light strip 15 is powered on. A worker holds the connecting plate 10 or the connecting pipe 11 with one hand, and uses the LED light strip 15 to obliquely irradiate the surface of the workpiece to polish and clean the impurities on the surface of the casting. While the grinding head 3 rotates, the fan blade 9 inside the support housing 1 rotates to extract the air outside the support housing 1 and spray it out from the corners of the opening 2 of the support housing 1, promoting air flow to disperse the dust generated during grinding, facilitating the worker's observation in cooperation with the LED light strip 15. After grinding, the outer side wall of the connecting plate 10 and the support pad 14 are used to stably place the device.
