Description

Technical Field

[0001] The utility model relates to the technical field of surface grinding equipment, in particular to a surface grinding device for aluminum products. Background Technique

[0002] When processing aluminum products, in order to ensure the smoothness of the surface of aluminum products, surface grinding work is often required. The utility model patent with the patent application number CN201821568606.5 discloses a hand-held device for grinding the surface edges and corners of silicon steel strips. The grinding wheel is driven by a motor to rotate, so that the grinding wheel can grind the surface and edges and corners of the silicon steel plate. The grinding wheel is easy to replace. The dust and burrs generated during the grinding process are blocked by the protective cover, which can avoid the scattering of dust and burrs everywhere and reduce the impact on the surrounding environment. It can effectively protect the physical health of the staff. According to the disclosed technical solution, when the existing surface grinding equipment is in use, on the one hand, the generated fine debris is easy to float into the air, which is not conducive to ensuring environmental safety and personnel health. On the other hand, when performing surface grinding work, the surface of the aluminum product is easily damaged due to excessive pressure of the grinding equipment on the aluminum product, which is not conducive to ensuring the safe grinding work of the aluminum product.

[0012] Beneficial effects: 1. When the aluminum product surface grinding device is performing grinding work, the motor drives the fan blade to rotate through the connecting rod, so that the machine sleeve generates suction on the card cover, causing air to pass through the brush and enter the inside of the card cover, and then be sucked upward into the inside of the machine sleeve by the fan blade. Under the guidance of the inclined plate, the one-way valve in the support sleeve is pushed open and enters the inside of the filter cartridge, and the debris is filtered by the filter cartridge. At the same time, the brush is used to block the flying debris, which can effectively filter and collect the grinding debris, effectively prevent the debris from soiling the surface of the aluminum product, and prevent the debris from flying, ensuring the environmental hygiene of the air and the health and safety of personnel.

[0013] 2. When the aluminum product surface grinding device is in use, hold the handle.

The inclined plate 17 is welded to the inner wall of the machine sleeve 1, the fan blade 11 is installed on the outer side of the connecting rod 10 through bolts, the machine sleeve 1 is sleeved outside the fan blade 11, the support sleeve 18 is welded to the other side of the machine sleeve 1, one side of the filter cartridge 19 is threadedly sleeved on the outer side of the support sleeve 18, the bottom of the inclined plate 17 is communicated with the support sleeve 18, the one-way valve 20 is installed inside the support sleeve 1, and the support sleeve 18 is unidirectionally communicated with the filter cartridge 19 through the one-way valve 20. When grinding work is carried out, the motor 3 drives the fan blade 11 to rotate through the connecting rod 10, so that the machine sleeve 1 generates suction on the clamping cover 5, enabling air to pass through the brush 6 and enter the inside of the clamping cover 5, and then being sucked upward into the inside of the machine sleeve 1 by the fan blade 11. Under the guidance of the inclined plate 17, the one-way valve 20 inside the support sleeve 1 is pushed open and enters the inside of the filter cartridge 19, and the debris is filtered out through the filter cartridge 19. At the same time, the brush 6 is used to block the splashing debris, which can effectively filter and collect the grinding debris, effectively avoid the debris from soiling the surface of the aluminum product, and prevent the debris from flying, ensuring the environmental hygiene of the air and the health and safety of personnel.

[0021] In this embodiment, the handle 2 is welded to one side of the machine sleeve 1, the motor 3 is installed inside the machine sleeve 1 by bolts, the top end of the connecting rod 10 is key-connected to the output shaft of the motor 3, the bottom end of the connecting rod 10 is welded to the top of the prism block 9, a prism groove 13 is formed inside the grinding disc 4, the prism block 9 is stuck inside the prism groove 13, a shield 12 is installed on the top of the grinding disc 4 by bolts, the shield 12 is stuck on the top of the prism block 9, the shield 12 is sleeved outside the connecting rod 10, the button 14 is installed on the bottom of the prism block 9 by bolts, the bottom of the prism block 9 is connected to the bottom of the prism groove 13 by a second spring 15, the bottom of the motor 3 is installed with a brush 16 by bolts, the brush 16 is sleeved on the outer side of the connecting rod 10, a storage battery 21 is installed inside the handle 2 by bolts, a switch 22 is installed on the bottom of the handle 2 by bolts, the storage battery 21 is connected to the switch 22 by an electric wire, the switch 22 is connected to the brush 16 by an electric wire, the brush 16 is connected to the button 14 by an electric wire, and the button 14 is connected to the motor 3 by an electric wire. When in use, hold the handle 2 by hand, and the motor 3 drives the grinding disc 4 to rotate through the connecting rod 10 and the prism block 9 to polish the aluminum product. When the downward pressure on the handle 2 by the person is relatively large, the machine sleeve 1 squeezes the connecting rod 10 downward through the motor 3, the connecting rod 10 drives the prism block to compress the second spring 15 downward until the prism block 9 drives the button 14 to be squeezed downward against the inner wall of the bottom of the prism groove 13, so that the button 14 closes the motor 3 through the brush 16 and stops the polishing work, so as to avoid damage to the surface of the aluminum product caused by the relatively large pressure applied by the person to the grinding disc 4, ensure the safe polishing work of the aluminum product, and further ensure the surface polishing quality of the aluminum product.

[0022] The surface grinding device for aluminum products provides electrical energy for all electrical equipment through the storage battery 21. During use, hold the handle 2, and the motor 3 drives the grinding disc 4 to rotate through the connecting rod 10 and the prism block 9 to grind the aluminum products. When the downward pressure on the handle 2 by the operator is relatively large, the machine sleeve 1 presses the connecting rod 10 downward through the motor 3. The connecting rod 10 drives the prism block to compress the second spring 15 downward until the prism block 9 drives the button 14 to press downward against the inner wall at the bottom of the prism groove 13. As a result, the button 14 closes the motor 3 through the carbon brush 16, stopping the grinding work, so as to avoid damage to the surface of the aluminum products caused by the relatively large pressure exerted by the operator on the grinding disc 4, ensuring the safe grinding work of the aluminum products, and thus ensuring the surface grinding quality of the aluminum products. During the grinding work, the motor 3 drives the fan blade 11 to rotate through the connecting rod 10, so that the machine sleeve 1 generates a suction force on the cover 5, causing air to pass through the brush 6 and enter the inside of the cover 5, and then be sucked upward into the inside of the machine sleeve 1 by the fan blade 11. Under the guidance of the inclined plate 17, it pushes open the one-way valve 20 in the branch sleeve 18 and enters the inside of the filter cartridge 19, and filters out the debris through the filter cartridge 19. At the same time, the flying debris is blocked by the brush 6, which can effectively filter and collect the grinding debris, effectively avoid the debris from soiling the surface of the aluminum products, and prevent the debris from flying, ensuring the environmental hygiene of the air and the health and safety of the personnel.
