[0002] A metal casting refers to an object with a certain shape, size and performance obtained by pouring molten metal into a pre-prepared mold by means of pouring, injection, suction or other casting methods, and then through subsequent processing means such as grinding after cooling. Metal casting is one of the basic processes in modern mechanical manufacturing. Metal castings are diverse in types and have a long history of use. They are widely used in manufacturing industries such as automobiles, ships, aerospace, agricultural machinery, machine tools and instruments. Since metal castings are formed by pouring and cooling, the surface of the formed castings has certain residual parts and burrs, etc., and usually the surface needs to be ground.

[0003] Disadvantages of the prior art: The grinding equipment for metal castings in the prior art will generate a large amount of debris and sparks during the grinding process, which is easy to cause environmental pollution, and the flying sparks will cause surrounding workers to be accidentally injured. At the same time, during the grinding process of the grinding device in the prior art, it is usually necessary to manually bring the metal casting close to the grinding sandpaper or grinding disc for grinding. This method is easy to cause the workers to be accidentally injured by the running grinding sandpaper or grinding disc, and the work efficiency is low. Summary of the Utility Model

[0019] Next, the technical solutions in the present invention will be clearly and completely described in conjunction with the accompanying drawings in the present invention. In addition, the forms of each structure described in the following embodiments are merely examples. A metal casting grinding device related to the present invention is not limited to the structures described in the following embodiments. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0020] The present invention provides a metal casting grinding device, as Figure 1 shown, including a support table 1. The right end of the support table 1 is fixedly connected to a grinding table 2. The front side of the top end of the support table 1 is fixedly connected to a dust-proof cover 3. Through the dust-proof cover 3, chips, sparks, etc. generated during the grinding process are prevented from splashing everywhere, causing environmental pollution or accidental injury to the staff. A plurality of support columns 4 are fixedly connected to the bottom ends of the support table 1 and the grinding table 2 at equal intervals. One side of the rear end of the support table 1 is fixedly connected to a mounting block 5. The top end of the mounting block 5 is fixedly installed with a grinding assembly 6. Through the mounting block 5, the stability of the grinding assembly 6 during operation is ensured. Two fixed columns 7 are fixedly connected to the top end of the support table 1 at equal intervals. The top ends of the two fixed columns 7 are jointly fixedly connected to a fixing frame 8. The right side of the top end of the grinding table 2 is fixedly installed with a cylinder 9. The output end of the cylinder 9 is fixedly connected to a fixing plate 10. The rear end of the support table 1 is fixedly connected to a collection box 11. Through the collection box 11, the generated chips are collected and processed. The position of the fixing plate 10 corresponds to the position of the grinding assembly 6. The fixing plate 10 is movably connected to the top surface of the grinding table 2. The metal casting is fixed to the top end of the grinding table 2 through the fixing plate 10.

[0021] Furthermore, as Figure 2As shown in the figure, the grinding assembly 6 includes a motor 61. The output end of the motor 61 is fixedly connected to a rotating shaft 62. The motor 61 enables the rotating shaft 62 to rotate. One end of the rotating shaft 62 away from the output end of the motor 61 is fixedly connected to a driving roller 63. The driving roller 63 is enabled to rotate by the rotating shaft 62. First limiting rings 64 are fixedly connected to both the front and rear ends of the driving roller 63. A grinding abrasive belt 65 is sleeved on the outer surface of the driving roller 63. Two driven rollers 66 are equidistantly arranged on the side of the inner wall of the grinding abrasive belt 65 away from the driving roller 63. The driving roller 63 drives the grinding abrasive belt 65 to rotate. At the same time, the grinding abrasive belt 65 rotates on the outer surfaces of the two driven rollers 66 to ensure the stability during rotation. The two driven rollers 66 support the grinding abrasive belt 65. A connecting block 67 is fixedly connected to the front end of the driven roller 66. A second limiting ring 68 is fixedly connected to the end of the driven roller 66 away from the connecting block 67. The first limiting ring 64 and the second limiting ring 68 ensure the stability of the grinding abrasive belt 65 during movement.

[0022] Further, as Figure 3 and Figure 4 shown in the figure, the motor 61 is fixedly installed at the top of the mounting block 5. The driving roller 63 and the driven rollers 66 are located inside the dust-proof cover 3. The dust-proof cover 3 plays a role in protection and dust prevention. The inner wall of the grinding abrasive belt 65 is sleeved on the outer surfaces of the driving roller 63 and the driven rollers 66 together. The right side of the outer surface of the grinding abrasive belt 65 is in contact with the left end of the grinding table 2. One ends of the two connecting blocks 67 away from the driven rollers 66 are fixedly connected to one side of the rear end of the fixed frame 8 at equal intervals. The metal casting is placed on the grinding table 2. The air cylinder 9 pushes the fixing plate 10 to move. The metal casting is moved towards the grinding abrasive belt 65 through the fixing plate 10. As the grinding abrasive belt 65 rotates, the surface of the metal casting is ground.

[0023] The working principle of the present utility model: First, place the metal casting to be ground on the top surface of the grinding table 2. Start the air cylinder 9 and the grinding assembly 6. The air cylinder 9 pushes the fixing plate 10 to move on the top surface of the grinding table 2, and pushes the metal casting to the surface of the grinding abrasive belt 65. Then, the motor 61 enables the rotating shaft 62 to rotate. The mounting block 5 ensures the stability of the motor 61 during operation. The rotating shaft 62 enables the driving roller 63 to rotate. The driving roller 63 drives the grinding abrasive belt 65 to rotate. At the same time, the grinding abrasive belt 65 rotates on the outer surfaces of the two driven rollers 66 to ensure the stability during rotation. The two driven rollers 66 support the grinding abrasive belt 65. The two driven rollers 66 ensure the stability of the connection with the fixed frame 8 through the connecting blocks 67. As the grinding abrasive belt 65 rotates, the surface of the metal casting is ground. The debris and sparks generated during the grinding process are blocked by the dust-proof cover 3, preventing them from splashing everywhere and causing environmental pollution or injuring the staff. The debris generated by grinding is collected by the collection box 11.
