[0024] As Figures 1 to 4 shown, a grinding device for metal casting processing provided by the present utility model includes a workbench 1, a bracket 2, an electric push rod 3, and a grinding mechanism 4. The left and right sides of the workbench 1 are fixedly connected to the top inside of the bracket 2. The electric push rod 3 is fixedly installed on the left and right sides of the top of the workbench 1. The output ends of the electric push rod 3 are fixedly connected to the left and right sides of the bottom of the grinding mechanism 4. Two through grooves 5 are opened on the top of the workbench 1.

[0026] As a technical optimization scheme of the present utility model, by setting the positioning mechanism 7, after the metal casting is placed on the top of the workbench 1, first move the metal casting to make its front side fit against the rear side of the fixing plate 73, and then by moving the connecting plate 72 forward, the clamping plate 71 can be driven to move forward to tightly position the rear side of the metal casting.

[0027] Referring to Figure 3 , the transmission mechanism 8 includes a mounting plate 81. A support plate 82 is fixedly connected to the front side of the bottom of the workbench 1.

The lead screw 84 is movably connected to the collection box 6, and the lead screw 84 is threadedly connected to the connecting plate 72.

[0028] As a technical optimization scheme of the present utility model, by setting the transmission mechanism 8, the mounting plate 81 can fix and limit the servo motor 83, and the support plate 82 can play a role in supporting the lead screw 84. By starting the servo motor 83, the output end of the servo motor 83 can drive the lead screw 84 to rotate. The rotation of the lead screw 84 can drive the connecting plate 72 to move back and forth, and the back-and-forth movement of the connecting plate 72 can drive the clamping plate 71 to move back and forth.

[0029] Reference Figure 4 Figure 4 [At the rear side of the grinding mechanism 4, a support plate 9 is fixedly connected. At the top of the support plate 9, a blower 10 is fixedly installed. The output end of the blower 10 is communicated with a connecting pipe 11.]

[0030] As a technical optimization scheme of the present utility model, by providing the support plate 9, the blower 10 and the connecting pipe 11, the support plate 9 can support and fix the blower 10 in position. By starting the blower 10, the wind generated by the blower 10 can be blown through the connecting pipe 11 to the top of the workbench 1, so that the metal debris on the top of the workbench 1 can be blown through the through groove 5 into the interior of the collection box 6.]

[0031] Reference Figure 4 Figure 4 [At the bottom of the support plate 9, a wind collection box 12 is fixedly connected. The end of the connecting pipe 11 away from the blower 10 is communicated with the right side of the wind collection box 12. At the left and right sides of the grinding mechanism 4, air outlet covers 13 are fixedly connected. Both sides of the front side of the wind collection box 12 are communicated with the rear sides of the air outlet covers 13 through pipes.]

[0032] As a technical optimization scheme of the present utility model, by providing the wind collection box 12 and the air outlet covers 13, the wind generated by the blower 10 can enter the interior of the wind collection box 12 through the connecting pipe 11, and then these winds can be blown through the air outlet covers 13 to the top of the workbench 1.]

[0033] Reference Figure 1 Figure 1 [On both the left and right sides of the clamping plate 71, baffle plates 14 are provided. The bottom of the baffle plates 14 is fixedly connected to the top of the workbench 1. At the bottom of the inner wall of the collection box 6, a drawer 15 is movably connected.]

[0034] As a technical optimization scheme of the present utility model, by providing the baffle plates 14 and the drawer 15, the baffle plates 14 can prevent the metal casting from colliding with the electric push rod 3, and at the same time can play a certain role in blocking the metal debris. The drawer 15 can collect the metal debris falling into the interior of the collection box 6.]

[0035] Reference Figure 1 Figure 1 [At the four corners of the bottom of the grinding mechanism 4, sliding rods 16 are fixedly connected. The other ends of the sliding rods 16 penetrate through the workbench 1 and extend to the bottom of the workbench 1. The sliding rods 16 are movably connected to the workbench 1. At the bottom of the surface of the sliding rods 16, limit rings 17 are fixedly connected.]

[0036] As a technical optimization scheme of the present utility model, by providing the sliding rods 16 and the limit rings 17, the sliding rods 16 can limit the movement of the grinding mechanism 4, thereby improving the stability of the up and down movement of the grinding mechanism 4. The limit rings 17 can prevent the sliding rods 16 from separating from the workbench 1.]

[0037] Working principle and usage process of the utility model: When in use, when it is necessary to polish a metal casting, first place the metal casting on the top of the workbench 1, then move the metal casting so that its front side fits against the rear side of the fixing plate 73, and then start the servo motor 83 to drive the lead screw 84 to rotate through the output end of the servo motor 83. The rotation of the lead screw 84 can drive the connecting plate 72 and the clamping plate 71 to move forward to tightly position the rear side of the metal casting. At this time, start the electric push rod 3 to drive the grinding mechanism 4 to move downward through the output end of the electric push rod 3. When the grinding mechanism 4 contacts the surface of the metal casting, grinding work can be carried out. The grinding mechanism 4 belongs to the prior art, and the structure and working principle of the grinding mechanism 4 in the comparative document (application number: CN202223013507.X) are the same, so it will not be elaborated here. Then, start the fan 10 to make the wind generated by the fan 10 pass through the connecting pipe 11, the air collecting box 12 and the air outlet hood 13 in sequence and blow towards the top of the workbench 1. At this time, the metal chips generated by grinding fall into the interior of the drawer 15 through the through groove 5 and the collecting box 6. After the processing is completed, the user can conveniently clean the metal chips by pulling out the drawer 15, thereby avoiding the metal chips from adhering to the surfaces of the workbench 1 and the metal casting.

[0038] In summary: For this grinding device for metal casting processing, by providing the through groove 5 and the collecting box 6, the chips generated by grinding can fall into the interior of the collecting box 6 through the through groove 5, solving the problem that a large amount of metal chips are generated when the surface of the metal casting is polished. If not cleaned in time, the chips will adhere to the surface of the workbench, affecting the processing work, and are likely to adhere to the surface of the processed casting during subsequent processing, thus reducing the quality and aesthetics of the finished product.
