[0030] The loading assembly 1 includes a mounting base 101, the upper end of the mounting base 101 is fixedly connected to a support frame 102, the upper end of the support frame 102 is fixedly connected to a hydraulic telescopic rod 103, and the output end of the hydraulic telescopic rod 103 is fixedly connected to a mounting block 104, the middle part of the mounting block 104 is slidably connected to a clamping block 105, and the upper end of the clamping block 105 is fixedly connected to a pair of clamping springs 106, and the upper ends of the pair of clamping springs 106 are fixedly connected to the upper end of the mounting block 104, and the end of the mounting block 104 on the same side as the clamping block 105 is also fixedly connected to a U-shaped placement plate 107.

[0031] The grinding assembly 2 includes a pair of grinding shells 201 fixedly connected to the upper end of the mounting base 101, a pair of upper and lower symmetrical connecting blocks 202 are slidably connected inside the grinding shells 201, a driving shell 203 is also fixedly connected to the lower end of the inner part of the grinding shell 201, and a servo motor 204 is fixedly connected to the inner part of the driving shell 203, a rotating shaft 205 is rotatably connected to the middle part of the pair of connecting blocks 202, and the lower end of the rotating shaft 205 is fixedly connected to the output end of the servo motor 204, a grinding roller 206 is fixedly connected to the middle part of the rotating shaft 205 and located between the pair of connecting blocks 202, one end of the pair of connecting blocks 202 is fixedly connected to an adjusting spring 207, and one end of the adjusting spring 207 is fixedly connected to the inner side wall of the grinding shell 201;

[0032] If the present solution needs to grind the corners of the metal house number plate casting 3 or the rectangular metal casting, it is only necessary to insert the metal house number plate casting 3 or the rectangular metal casting between the clamping block 105 and the U-shaped placing plate 107, and clamp the metal house number plate casting 3 by the clamping spring 106. After clamping, the hydraulic telescopic rod 103 and the servo motor 204 are started, and the hydraulic telescopic rod 103 pushes the mounting block 104 forward, so as to push the metal house number plate casting 3 placed on the upper end thereof into between a pair of grinding rollers 206;

[0033] The servo motor 204 starts to rotate the rotating shaft 205 fixedly connected to its output end, and the rotation direction of the pair of servo motors 204 is toward the mounting block 104. The rotating shaft 205 rotates to drive the grinding roller 206 fixedly connected to the middle part to rotate. The pair of grinding rollers 206 rotate to grind the metal house number casting 3. When the metal house number casting 3 is inserted between the pair of grinding rollers 206, the grinding roller 206 is squeezed to drive the connecting block 202 to squeeze the adjusting spring 207. By adjusting the spring 207, the grinding roller 206 can be better fitted with the corners of the metal house number casting 3, and it can also adapt to metal house number castings 3 with different lengths and widths.

[0034] See also Figure 1 to Figure 2 , one end of the clamping block 105 is provided with a curved surface;

[0040] See also Figure 3 , the diameter of the driving housing 203 is smaller than the diameter of the grinding roller 206;

[0041] In this solution, the diameter of the driving housing 203 is set to be smaller than the diameter of the grinding roller 206 , so that the metal door plate casting 3 can better contact the middle part of the grinding roller 206 .

[0042] Working principle: If it is necessary to grind the edges and corners of the metal house number plate casting 3 or the rectangular metal casting, just insert the metal house number plate casting 3 or the rectangular metal casting between the clamping block 105 and the U-shaped placing plate 107, clamp the metal house number plate casting 3 through the clamping spring 106, and start the hydraulic telescopic rod 103 and the servo motor 204 after clamping. The hydraulic telescopic rod 103 pushes the mounting block 104 forward, so as to push the metal house number plate casting 3 placed on the upper end thereof into between a pair of grinding rollers 206;

[0043] The servo motor 204 starts to rotate the rotating shaft 205 fixedly connected to its output end, and the rotation direction of the pair of servo motors 204 is toward the mounting block 104. The rotating shaft 205 rotates to drive the grinding roller 206 fixedly connected to the middle part to rotate. The pair of grinding rollers 206 rotate to grind the metal house number casting 3. When the metal house number casting 3 is inserted between the pair of grinding rollers 206, the grinding roller 206 is squeezed to drive the connecting block 202 to squeeze the adjusting spring 207. By adjusting the spring 207, the grinding roller 206 can be better fitted with the corners of the metal house number casting 3, and it can also adapt to metal house number castings 3 with different lengths and widths.
