[0017] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6The utility model proposes a fluid grinding device for metal workpiece processing, including a water sandblasting machine housing 1, a grinding chamber is provided in the water sandblasting machine housing 1, and there are existing structures such as a water sandblasting gun. The grinding working principle of the device refers to a manual sandblasting machine with a model of HET-1010A. In actual operation, there are two common methods. One is to clamp the workpiece by a fixture, and the water sandblasting gun is driven by a driving structure such as a motor and a cylinder to drive the water sandblasting gun to evenly grind the surface of the metal workpiece. The other is that the staff holds the metal workpiece in one hand and the water sandblasting gun in the other hand to grind the surface of the metal workpiece. During operation, The staff is required to put their hands into the gloves at the front end of the water sandblasting machine housing 1 to reduce damage to the staff's hands. After the metal workpiece is polished, the staff is required to open the box door 2 to take out the polished metal workpiece, and then replace the metal workpiece and put it into the polishing chamber, which will waste time and affect the polishing efficiency; an opening connected to the polishing chamber is opened on one side of the water sandblasting machine housing 1, and a box door 2 capable of sealing the side opening of the water sandblasting machine housing 1 is installed on the water sandblasting machine housing 1. It should be noted that the box door 2 in the present device is located at the front end of the water sandblasting machine housing 1, and the observation window and the operating gloves are installed on the box door 2.
[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown in the figure, a mounting opening is provided on the box door 2, and a conveying cylinder 3 is fixedly installed in the mounting opening. A feeding port 4 and a material changing port 5 are provided on the conveying cylinder 3. The feeding port 4 and the material changing port 5 are respectively located on the inner and outer sides of the water sandblasting machine box body 1. A conveying structure is rotatably installed in the conveying cylinder 3, and the conveying structure is used to convey the metal workpiece in and out of the grinding chamber. The conveying structure can also separate the feeding port 4 from the material changing port 5. In actual operation, the staff can convey the metal workpiece into the grinding chamber through the conveying structure, and at the same time, the polished metal workpiece can be conveyed out through the conveying structure without manually opening the box door 2, thereby reducing the time of opening and closing the box door 2 and improving work efficiency. In addition, the conveying structure can completely isolate the feeding port 4 from the material changing port 5, so as to avoid the internal water and the sand in the water from splashing out and causing unnecessary trouble.
[0019] The conveying structure includes a conveying motor 6, a rotating shaft 7, a mesh plate 8 and a partition plate 9; the partition plate 9 is an arc-shaped plate, and the concave opening of the partition plate 9 is oriented in the same direction as the rotation direction of the partition plate 9. Figure 5 The arrow direction in is the rotation direction of the partition plate 9. Figure 5As shown in the figure, the conveying motor 6 is fixedly installed in the conveying cylinder 3, the rotating shaft 7 is fixedly installed on the output shaft of the conveying motor 6, the mesh disk 8 is mounted on the rotating shaft 7, and the mesh disk 8 divides the conveying cylinder 3 into a conveying cavity and an installation cavity arranged up and down, and the diameter of the mesh disk 8 is the same as the inner diameter of the conveying cylinder 3; the feed port 4 and the material change port 5 are both connected to the conveying cavity, and the number of the partition plates 9 is at least six, and the six partition plates 9 are arranged in a ring shape on the outer periphery of the rotating shaft 7. When the partition plates 9 make a circular motion, the side of the partition plates 9 away from the rotating shaft 7 slides along the inner wall of the conveying cylinder 3 When the partition plate 9 rotates, when the metal workpiece and the mesh plate 8 at the bottom slide or roll, the partition plate 9 will press against the metal workpiece to push the metal workpiece to rotate, and the metal workpiece can move along the partition plate 9 to the middle position of the concave surface of the partition plate 9, thereby reducing the possibility of the metal workpiece falling down; in actual situations, it is necessary to design the opening of the feed port 4 according to actual conditions, and it is necessary to ensure that when the partition plate 9 rotates, the partition plate 9 always presses against the inner wall of the conveying cylinder 3, thereby ensuring that the water and sand in the grinding chamber will not splash out.
[0020] The opening width of the material changing port 5 is the same as the spacing between the outermost sides of two adjacent partition plates 9; the installation cavity is connected to the grinding chamber. When in use, it is necessary to ensure that the opening size of the material changing port 5 is relatively small to ensure that the metal workpiece can be normally taken and placed. In addition, during the grinding operation, there is no metal workpiece in the space between the two partition plates 9 connected to the material changing port 5, thereby reducing the water sprayed from the water sandblasting gun from impacting the metal workpiece and causing damage to the metal workpiece, thereby ensuring the quality of the metal workpiece. In addition, water splashed onto the partition plate 9 through the material changing port 5 will flow down, flow through the mesh plate 8 to the installation cavity, and then flow back to the grinding chamber, ensuring the recovery of water sand and reducing pollution.
[0021] The specific working principle is as follows: the staff puts a metal workpiece in the space between the partition plates 9 exposed to the outside of the water sandblasting machine housing 1, and then the conveying motor 6 works to drive the mesh disk 8 and the partition plate 9 to rotate, and conveys the metal workpiece into the grinding chamber, so that the first metal workpiece is exposed to the material change port 5. The staff inserts both hands into the gloves through the operating window on the box door 2, and then takes out the metal workpiece exposed in the material change port 5 for grinding. When the grinding of the metal workpiece is completed, the metal workpiece is placed on the mesh disk 8 between the original two partition plates 9, and then the conveying motor 6 is driven to rotate. During work, the unpolished metal workpiece is conveyed to the material changing port 5, and the polished metal workpiece is hidden in the conveying tube 3 to reduce the impact on the metal workpiece due to incorrect operation. In addition, a workpiece table can be placed at the front end of the water sandblasting machine case 1. After the polishing of the originally placed metal workpiece is completed, one hand can be taken out of the glove, the polished metal workpiece is taken out and placed on the workpiece table, and the metal workpiece to be polished is placed on the mesh disk 8 for conveying, which can reduce the time of opening and closing the box door 2, and can also reduce the splashing of water and sand, ensure the recovery of water and sand, and reduce pollution.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
