Technical Field

[0001] The utility model relates to the technical field of metal part polishing, in particular to a grinding and polishing machine for metal part processing. Background Art

[0002] After metal parts are processed, they will have burrs and relatively rough surfaces. For industries with high precision requirements, such metal parts cannot be used. Therefore, a grinding and polishing machine is needed to grind and polish the metal parts.

[0003] However, the current grinding and polishing machines have great limitations. It is difficult for a single device to grind and polish metal parts of different sizes and specifications. Moreover, during the grinding and polishing process, the generated iron filings are very likely to endanger the safety of the staff. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a grinding and polishing machine for metal part processing, which solves the problems in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A grinding and polishing machine for metal part processing, including a table body. Between the inner walls on the front and rear sides of the table body, there are evenly distributed rotating shafts rotatably connected. The outer circles of the rotating shafts are all fixedly connected with drums. On one side of the front end of the table body, there is a first motor fixedly connected. The output end of the first motor penetrates the table body and is fixedly connected with one of the rotating shafts. Between the outer circles of the two drums on both sides, there is a conveyor belt sleeved. At the middle position on the rear side of the table body, there is a support frame. On the top of the support frame, there is a telescopic column fixedly connected. One end of the telescopic column is fixedly connected with a connecting block. On the front side of the connecting block, there is a linkage shaft fixedly connected. One end of the linkage shaft is rotatably connected with a first abrasive belt wheel. At the middle position on the rear side of the table body, there is a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly connected with a hydraulic rod. One end of the hydraulic rod is fixedly connected with a second motor. The output end of the second motor is fixedly connected with a second abrasive belt wheel. At the middle position on the top of the table body, there is a protective cover.

[0006] By adopting the above technical solution, the grinding and polishing equipment can adapt to metal parts of different sizes and specifications for grinding, and at the same time can ensure the safety of the operators, and the safety factor is improved.

[0007] As a further description of the above technical solution: There is a material box on one side of the table body, and the material box is located below one end of the conveyor belt.

[0008] By adopting the above technical solution, after the metal parts are ground and polished, the conveyor belt conveys the parts and drops them into the material box for centralized collection.

[0009] As a further description of the above technical solution: Support columns are fixedly connected to the four corners of the bottom of the table body.

[0010] By adopting the above technical solution, the support columns raise the height of the table body and also improve the stability of the equipment, avoiding shaking during the operation of the equipment and affecting the work of the equipment.

[0011] As a further description of the above technical solution: The first abrasive belt wheel and the second abrasive belt wheel are located in the same plane, and the diameter of the second abrasive belt wheel is larger than that of the first abrasive belt wheel.

[0012] By adopting the above technical solution, the two abrasive belt wheels are located in the same plane. While effectively driving the rotation of the abrasive belt, the metal parts being polished are kept moving in the same direction.

[0013] As a further description of the above technical solution: The hydraulic cylinder is located below the inner side of the support frame.

[0014] By adopting the above technical solution, the operation of the hydraulic cylinder changes the height position of the second abrasive belt wheel. The hydraulic cylinder is located below the support frame to ensure that the two abrasive belt wheels are on the same horizontal plane, avoiding equipment operation failures.

[0015] As a further description of the above technical solution: An abrasive belt is arranged outside the first abrasive belt wheel and the second abrasive belt wheel.

[0016] By adopting the above technical solution, the abrasive belt is driven by the rotation of the first abrasive belt wheel and the second abrasive belt wheel to polish the metal parts.

[0017] As a further description of the above technical solution: A third motor is fixedly connected to the middle positions on the left and right sides of the support frame, and a pressing roller is fixedly connected to the output end of the third motor.

[0018] By adopting the above technical solution, when the third motor is started, it drives the pressing roller to rotate. The pressing roller presses the metal parts, which can restrict the metal parts from being conveyed along the conveyor belt and avoid position deviation, resulting in an unsatisfactory polishing effect.

[0019] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0020] 1. A grinding and polishing machine for processing metal parts provided by the present utility model first adds a hydraulic cylinder on one side of the table body. By the telescopic movement of the hydraulic rod, the height of the second motor is changed, thereby driving the change of the position of the second abrasive belt wheel, which can adapt to the grinding and polishing of metal parts of different sizes and enhance the flexibility of the equipment.

[0021] 2. A grinding and polishing machine for metal parts processing provided by the present utility model is provided with a protective cover at the middle position on the top of the table body to protect the staff, avoiding the harm of metal waste chips or dust to the staff during the grinding and polishing process, which is beneficial to ensuring the safety of the operators.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0028] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0029] Combined with Figure 1 and Figure 3, A polishing machine for metal parts processing of the present utility model includes a table body 1. On one side of the front end of the table body 1, a first motor 2 is fixedly connected. Between the inner walls of the front and rear sides of the table body 1, uniformly distributed rotating shafts 4 are rotatably connected, and a roller 3 is fixedly connected to the outer ring of each rotating shaft 4. When the first motor 2 is started, the output end drives the rotating shaft 4 to rotate. The output end of the first motor 2 penetrates the table body 1 and is fixedly connected to the rotating shaft 4 on one side. The first motor 2 drives the roller 3 to rotate by connecting one end of the rotating shaft 4, and the other end of the rotating shaft 4 rotates inside the table body 1 to drive the roller 3 to rotate. A conveyor belt 5 is sleeved between the outer rings of the two rollers 3 on both sides. The roller 3 rotates driven by the first motor 2, and the friction between the roller 3 and the conveyor belt 5 drives the conveyor belt 5 to move. On one side of the table body 1, there is a support frame 7. At the top of the support frame 7, a telescopic column 8 is fixedly connected. At the inner bottom of the telescopic column 8, there is a cylinder (not shown in the figure). The cylinder inside the telescopic column 8 pushes the telescopic column 8 to expand and contract, which is convenient for the first abrasive belt wheel 11 and the second abrasive belt wheel 15 to tighten and fix the abrasive belt 16, avoiding the inability of the abrasive belt 16 to polish the metal parts. One end of the telescopic column 8 is fixedly connected to a connecting block 9. On the front side of the connecting block 9, a linkage shaft 10 is fixedly connected. One end of the linkage shaft 10 is rotatably connected to a first abrasive belt wheel 11. The first abrasive belt wheel 11 rotates driven by the abrasive belt 16, and the surface of the first abrasive belt wheel 11 is smooth. At the four corners of the bottom of the table body 1, support columns 20 are fixedly connected, and the support columns 20 improve the stability of the equipment during operation. On one side of the table body 1, there is a material box 6, and the material box 6 is located below one end of the conveyor belt 5. The first abrasive belt wheel 11 and the second abrasive belt wheel 15 are in the same plane, and the diameter of the second abrasive belt wheel 15 is larger than that of the first abrasive belt wheel 11. The second abrasive belt wheel 15 is directly controlled by a second motor 14. The larger diameter of the second abrasive belt wheel 15 is beneficial to increasing the friction force and enhancing the polishing effect.

[0030] Combined with Figure 2 , on one side of the table body 1, there is a hydraulic cylinder 12. The output end of the hydraulic cylinder 12 is fixedly connected to a hydraulic rod 13. When the hydraulic cylinder 12 operates, the internal piston pushes the hydraulic rod 13 to extend upward. One end of the hydraulic rod 13 is fixedly connected to a second motor 14. The hydraulic rod 13 extends upward to raise the position of the second motor 14, and the hydraulic rod 13 retracts, and the position of the second motor 14 drops. The output end of the second motor 14 is fixedly connected to a second abrasive belt wheel 15. When the second motor 14 is started, the output end drives the second abrasive belt wheel 15 to rotate. Since the first abrasive belt wheel 11 and the second abrasive belt wheel 15 tighten the abrasive belt, the second abrasive belt wheel 15 rotates, and due to the friction force, it drives the abrasive belt 16 to rotate. The hydraulic cylinder 12 is located below the inner side of the support frame 7 to ensure that when the hydraulic cylinder 12 operates, the second abrasive belt wheel 15 and the first abrasive belt wheel 11 are in the same horizontal plane.

[0031] Combined with Figure 1, a protective cover 19 is provided at the middle position of the top of the frustum 1. The protective cover 19 effectively blocks the metal waste generated during the grinding and polishing of metal parts, preventing these iron chips from flying out and hurting the operators. A sand belt 16 is provided outside the first sand belt wheel 11 and the second sand belt wheel 15. Third motors 17 are fixedly connected to the middle positions on the left and right sides of the support frame 7. The output end of the third motor 17 is fixedly connected to a pressing roller 18, and the pressing roller 18 presses the metal parts on the conveyor belt 5 to prevent the parts from shifting in position.

[0032] Working principle: First, place the metal part at one end of the conveyor belt 5. Start the first motor 2, and the conveyor belt 5 starts to work to convey the metal part. Start the third motor 17, and the output end drives the pressing roller 18 to rotate, restricting the moving direction of the metal part during grinding to prevent the part from shifting in position and being incompletely ground. Then start the second motor 14 to drive the sand belt 16 to rotate. At the same time, the telescopic column 8 and the hydraulic cylinder 12 operate simultaneously to adjust the height of the sand belt 16 to adapt to the size of the metal part. During the grinding and polishing process, the protective cover 19 blocks the flying iron chips.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
