Description

Technical Field

[0002] Metal parts generally refer to parts or components made of metal used in manufacturing or construction, and their shapes, sizes and uses vary. In the process of metal parts processing, grinding is one of the common steps, which is used to remove burrs, flaws or irregular shapes on the surface to make the surface smooth and meet the design requirements. However, the grinding process involves the contact between the high-speed rotating grinding tool and the metal parts, which will produce flying metal debris, dust or chips, which will cause harm or pollution to the operator, equipment or environment. Therefore, the grinding device used for metal parts processing needs to have a protective function to ensure the safety of the operator and the cleanliness of the environment, so a metal parts processing grinding device with a protective function is needed.

[0003] When the existing grinding device for metal parts processing with protective function is in use, the waste chips, dust and sparks generated in the grinding process are fully absorbed through the action of the fan inside the protective box, with the cooperation of the protective cover and the absorption hose. However, when this method is used, the protective cover cannot automatically provide protection for the grinding site, resulting in metal debris, cutting chips and dust flying everywhere, directly threatening the safety of the operator. These flying debris may hit the operator's body, causing punctures or other injuries. The flying debris not only endangers the safety of the operator, but also makes the working environment unsafe. The flying debris may break the equipment or other nearby objects, causing additional damage or danger. Utility Model Content

[0023] The support frame 2 fixes the workbench 1. Under the action of the support frame 2, the stability of the workbench 1 is improved. The support frame 2 fixes the placement plate 3, and the placement plate 3 fixes the motor 10. The main function of the placement plate 3 is to provide support and fix the motor 10, which ensures that the motor 10 can be firmly mounted on the equipment so as to transmit power to other components. The motor 10 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the driving pulley 12 to rotate. The driving pulley 12 drives the driven pulley 14 to rotate through the belt 13, and the driven pulley 14 drives the rotating rod 15 to rotate. The rotating rod 15 drives the driven bevel gear 17 and the threaded rod 18 to rotate through the driving bevel gear 16. The threaded rod 18 drives the moving sleeve 19 to move, and the moving sleeve 19 moves to drive the protective cover 21 to slide up and down on the outside of the limit rod 20. The limit rod 20 plays a limiting role, so that the protective cover 21 can slide up and down on a fixed track, thereby improving the stability of the protective cover 21 when it moves up and down.

[0024] Reference Figure 3 A fixed frame 22 is fixedly connected to the upper part of the workbench 1, and a grinding assembly is fixedly connected to the bottom of the fixed frame 22. The grinding assembly includes a hydraulic cylinder 24, which is fixedly connected to the bottom of the fixed frame 22. The other end of the hydraulic cylinder 24 is fixedly connected to a grinding mechanism 23. A partition 9 is fixedly connected to the inside of the workbench 1, and the grinding mechanism 23 is arranged on the upper part of the partition 9.

[0025] The workbench 1 fixes the fixed frame 22, and the fixed frame 22 fixes the hydraulic cylinder 24. The output end of the hydraulic cylinder 24 pushes the grinding mechanism 23 to move up and down for height adjustment. Under the action of the grinding mechanism 23, metal parts can be ground. Metal parts can be placed on the upper part of the partition 9, and waste chips during grinding can fall downward through the partition 9.

[0026] Reference Figure 1-Figure 3 A fan 4 is fixedly connected to the upper part of the placement plate 3, a connecting hose 5 is fixedly connected to the input end of the fan 4, and a waste box 6 is fixedly connected to the other end of the connecting hose 5. A waste hopper 7 is fixedly connected to the bottom of the workbench 1, and the bottom of the waste hopper 7 is fixedly connected to the waste box 6. A filter plate 8 is arranged inside the waste hopper 7, and the filter plate 8 is arranged on the upper part of the waste box 6. The front part of the waste box 6 is rotatably connected to a box door, and the waste box 6 is fixedly connected to the upper part of the placement plate 3.

[0027] The placement plate 3 fixes the fan 4 and the waste box 6. The placement plate 3 provides a solid supporting platform that can firmly support the weight of the fan 4 and the waste box 6, which helps to prevent the fan 4 from shaking or shifting during operation and maintain the stability of the fan 4. The fan 4 extracts waste chips through the connecting hose 5. Under the action of wind force, the waste chips on the upper part of the partition 9 are transported to the inside of the waste hopper 7. The filter plate 8 can effectively filter the waste chips and prevent larger waste particles from entering the fan 4. This can avoid damage to the fan 4 by the waste chips and extend the service life of the fan 4. The waste box 6 is used to collect and store waste chips. Opening the box door makes it convenient for the staff to clean the waste chips inside the waste box 6.

[0028] Working principle: When the grinding mechanism 23 grinds the metal parts, the motor 10 is started, the output end of the motor 10 drives the rotating shaft 11 to rotate, the rotating shaft 11 drives the driving pulley 12 to rotate, the driving pulley 12 drives the driven pulley 14 to rotate through the belt 13, the driven pulley 14 drives the rotating rod 15 to rotate, the rotating rod 15 drives the driving bevel gear 16 to rotate, the driving bevel gear 16 drives the meshing driven bevel gear 17 to rotate, the driven bevel gear 17 drives the threaded rod 18 to rotate, under the action of the limit rod 20, the movable sleeve 19 drives the protective cover 21 to move up and down, when the protective cover 21 covers the workbench 1, the grinding mechanism 23 is started to grind the metal parts, when the grinding work is completed, the motor 10 is started again to move the protective cover 2 1 can be raised upward, so that the protective cover 21 can automatically protect the grinding place, can effectively block the splashing of debris, cutting chips and dust, help reduce the occurrence of accidents, reduce the risk of equipment damage and work environment pollution, and improve the safety of the workplace. When the grinding mechanism 23 is grinding the metal parts, the fan 4 is started, and the fan 4 extracts the waste chips through the connecting hose 5. The fan 4 generates suction, so that the waste chips on the upper part of the partition 9 fall into the waste hopper 7, and then are transported to the inside of the waste box 6 by the waste hopper 7, thereby effectively collecting and storing the waste chips, keeping the working area clean and tidy, helping to improve the comfort and safety of the working environment, and reducing the time and cost of cleaning work.
