Description

Technical Field

[0001] The utility model relates to the field of aluminum alloy die casting processing equipment, in particular to an aluminum alloy die casting surface grinding device. Background Art

[0002] Aluminum alloy die castings are aluminum or aluminum alloy parts manufactured by the die-casting process. Aluminum alloy die castings have good mechanical properties, dimensional stability and corrosion resistance, so they are widely used in automobiles, electronic equipment, aerospace, construction and other industrial fields. They can be manufactured with complex shapes and fine features, but after high-pressure injection molding, aluminum alloy die castings may have defects such as pores and looseness on their surfaces. These defects may affect the performance of the product. Grinding devices are needed to remove these defects, improve the flatness of the surface of aluminum alloy die castings, and make the surface of aluminum alloy die castings smoother and flatter.

[0003] At present, the grinding devices used for aluminum alloy die-castings include automatic grinding and manual grinding. In manual grinding, a worker holds the aluminum alloy die-casting and approaches it to the grinding disk, and grinds the surface of the aluminum alloy die-casting with the grinding disk. Such grinding efficiency is low, and a large amount of debris will be generated during the grinding process, affecting the health safety of the workers. In automatic grinding, the aluminum alloy die-casting is placed on the top of the processing table, and the grinding disk is driven by a mechanical arm to move on the surface of the aluminum alloy die-casting, so as to grind the surface of the aluminum alloy die-casting. However, after the grinding disk grinds one side of the aluminum alloy die-casting, the worker needs to manually turn the aluminum alloy die-casting over so that the grinding disk can grind the other side. Such operation is relatively cumbersome and the grinding efficiency is low, which affects the processing efficiency of the aluminum alloy die-castings.

[0004] Therefore, it is necessary to provide a new aluminum alloy die casting surface grinding device to solve the above technical problems. Utility Model Content

[0026] The extrusion assembly 3 includes a cylinder 29, a limiting ring 10, an elastic member and an extrusion column 11. One end of the cylinder 29 is fixedly connected to the inner wall of the processing table 1 away from the mounting column 4. One end of the limiting ring 10 is movably connected to the output end of the cylinder 29. The extrusion column 11 is located inside the limiting ring 10, and the extrusion column 11 can move inside the limiting ring 10. The two ends of the elastic member are respectively fixedly connected to one side of the inner wall of the limiting ring 10 and one end of the extrusion column 11. The elastic member is a spring 12. One end of the spring 12 is fixedly connected to one side of the inner wall of the limiting ring 10. The other end of the spring 12 is fixedly connected to one end of the extrusion column 11 located inside the limiting ring 10. The spring 12 reduces vibration and impact caused by sudden contact, protecting the surface of the aluminum alloy die casting 19 from damage.

[0027] The driving member is a motor 13, which is fixed inside the processing table 1. The output end of the motor 13 passes through one side of the inner wall of the mounting groove and is fixedly connected to one side of the rotating disk 6. The placement component 2 includes a placement table 14 and a cylinder three 15. The cylinder three 15 is fixed inside the processing table 1, and the cylinder three 15 push rod passes through the bottom end of the inner wall of the processing table 1 and is fixedly connected to the bottom of the placement table 14. A plurality of telescopic parts are arranged on the top of the placement table 14. The telescopic parts include a telescopic rod 16 and a spring two 17. A plurality of storage grooves 18 matching the telescopic rod 16 are arranged on the top of the placement table 14.

The grinding disc 21 is driven to move by the robotic arm 20, and the surface of the aluminum alloy die-casting 19 is grinded by the grinding disc 21.

[0028] The working principle provided by the utility model is as follows: an aluminum alloy die-casting 19 is placed on the top of a placing table 14, and the multiple telescopic rods 16 arranged on the top of the placing table 14 are squeezed by the weight of the aluminum alloy die-casting 19, so that the multiple telescopic rods 16 are respectively moved into the multiple storage grooves 18 and squeeze the spring 2 17, and the aluminum alloy die-casting 19 is limited by the telescopic rods 16 that are not squeezed into the storage grooves 18 to prevent the aluminum alloy die-casting 19 from deflecting during the grinding process, and because a plurality of protruding blocks are arranged on the top of the telescopic rods 16, the friction between the aluminum alloy die-casting 19 and the telescopic rods 16 can be further increased, and the stability of the aluminum alloy die-casting 19 is increased, and the grinding disc 21 is driven by the mechanical arm 20 to move, and the surface of the aluminum alloy die-casting 19 is grinded by the grinding disc 21;

[0029] When it is necessary to grind other surfaces of the aluminum alloy die-casting 19, the cylinder 2 9 drives the limit ring 10 and the extrusion column 11 to move toward the aluminum alloy die-casting 19, so that the end of the extrusion column 11 away from the limit ring 10 contacts the surface of the aluminum alloy die-casting 19, and the extrusion column 11 moves toward the inside of the limit ring 10, and at the same time squeezes the spring 12. When the extrusion column 11 contacts the surface of the aluminum alloy die-casting 19, the spring 12 reduces the vibration and impact caused by the sudden contact, and protects the surface of the aluminum alloy die-casting 19 from damage. At the same time, the cylinder 15 contacts the other surface of the aluminum alloy die-casting 19, and the cylinder 15 and the extrusion column 11 clamp and limit the aluminum alloy die-casting 19, and the cylinder 3 15 is started to drive the placement table 14 to move toward the bottom end of the inner wall of the processing table 1, so as to prevent the processing table 1 from causing an impact when the aluminum alloy die-casting 19 is turned over;

[0030] Start the motor 13, and the rotating disk 6 is driven to rotate by the motor 13. Since the rotating disk 6 and the movable disk 7 are connected by the synchronous belt 8, the movable disk 7 will be driven to rotate synchronously when the rotating disk 6 rotates, and the rotation of the movable disk 7 will drive the cylinder 15 to rotate, so that the aluminum alloy die-casting 19 clamped by the cylinder 15 and the extrusion column 11 is turned over, and since the limit ring 10 is movably connected to the output end of the cylinder 2 9, it will not be affected when the aluminum alloy die-casting 19 is turned over.
