Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a dual-station automated flexible grinding equipment for low-pressure aluminum alloy castings. Background Technology

[0002] Low-pressure casting of aluminum alloys is a common casting process. It involves molten aluminum alloy and pouring it into a metal mold. Low pressure is used to fill the entire mold with molten metal, which then cools and solidifies within the mold, ultimately resulting in an aluminum alloy casting of the desired shape. Low-pressure casting of aluminum alloys has advantages such as low cost, high production efficiency, and controllable product quality, and is therefore widely used in industries such as automotive, aerospace, and electronics. After casting, aluminum alloy low-pressure castings will inevitably have some flash at the parting line. Even with the use of trimming equipment, the flash cannot be completely removed, leaving residues or areas that cannot be cut with trimming equipment, resulting in poor product appearance. Currently, the industry mainly relies on manual removal of flash that cannot be removed with trimming equipment. However, due to the irregular edges of the product, it is difficult to control the amount of grinding manually, making the operation difficult and inefficient. Utility Model Content

[0024] In practical use: A mounting plate 41 is installed at the bottom of the fixed base 3, and mounting seats 42 are installed at both ends of the mounting plate 41. A flexible floating spindle 43 is installed on the surface of one mounting seat 42. When the flexible floating spindle 43 drives the first grinding wheel 44 to rotate, when the first grinding wheel 44 contacts the workpiece, the flexible floating spindle 43 can automatically adjust the position and angle of the first grinding wheel 44 according to the actual shape of the workpiece surface, thereby achieving precise grinding of workpieces with complex shapes. The grinding motor 45 on the surface of the other mounting seat 42 rotates to drive the second grinding wheel 46 to rotate to perform initial grinding on the surface and edges of the aluminum alloy low-pressure casting, removing obvious flash. Through the set dual-station grinding, it can replace the manual grinding method and improve grinding efficiency.

[0025] Please see Figure 1 , Figure 3 The fixing component 5 includes a slide 51 disposed on the surface of the worktable 1.

[0026] In practical use: A workpiece placement platform 52 is installed on the top of the slide table 51. The aluminum alloy low-pressure casting is placed on the surface of the rubber pad 53. The rubber pad 53 has a soft structure and can protect the workpiece from being scratched. By rotating the fixing rod 55 threaded at the front end of the L-shaped support arm 54, the workpiece is fixed by the fixing rod 55, so that the workpiece remains stable during the grinding process.

[0028] In practical use: A rotating motor 6 is installed on the surface of the fixed base 3. After the rotating motor 6 rotates, it drives the rotating shaft 7 in the middle of the mounting plate 41 to rotate through the coupling 8. The rotation of the rotating shaft 7 drives the mounting plate 41 to rotate accordingly, thereby allowing the first grinding wheel 44 and the second grinding wheel 46 to be switched according to the grinding process to meet the grinding requirements.

The dust removal suction pipe 15 is set on one side of the first grinding wheel 44 and the second grinding wheel 46 respectively. The flying dust particles generated during the grinding process are adsorbed by the dust removal suction pipe 15, which plays a role in dust reduction.

[0035] A mounting plate 41 is installed at the bottom of the fixed base 3. Mounting seats 42 are installed at both ends of the mounting plate 41.
