Description

Technical Field

[0001] The present application relates to the field of magnesium alloy grinding, and in particular to a grinding device for magnesium alloy castings. Background Art

[0002] Magnesium alloy is an alloy composed of magnesium and other elements. Its characteristics are: low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater impact load bearing capacity than aluminum alloy, and good resistance to corrosion from organic matter and alkali. Currently, magnesium-aluminum alloy is the most widely used, followed by magnesium-manganese alloy and magnesium-zinc-cobalt alloy. It is mainly used in aviation, aerospace, transportation, chemical industry, rocket and other industrial sectors. It is the lightest metal among practical metals. The specific gravity of magnesium is about 2 / 3 of aluminum and 1 / 4 of iron. It is the lightest metal among practical metals, with high strength and high rigidity. When magnesium alloy materials are produced and processed, the side edges of the magnesium alloy materials need to be polished.

The utility model relates to the field of grinding devices for the production of magnesium alloy materials, and in particular to a grinding device for facilitating the production of magnesium alloy materials, comprising a workbench, characterized in that limiting mechanisms are symmetrically arranged on both sides of the top surface of the workbench, a first grinding mechanism is arranged on the top surface of the workbench and located between one side of the two limiting mechanisms, a limiting groove is provided on the top surface of the workbench and located outside the other side of the two limiting mechanisms, a support frame is slidably installed in the limiting groove, and the support frame is supported. A second grinding mechanism is provided on the bottom end surface of the support frame. In the above application document, the magnesium alloy material is limited and clamped by a limiting mechanism. At the same time, the side edge of one side of the magnesium alloy material is ground by the first grinding mechanism, and the side edge of the other side of the magnesium alloy material is ground by the second grinding mechanism, thereby improving the grinding efficiency of the magnesium alloy material. However, it can only grind two side edges of the magnesium alloy material at a time, and the direction of the magnesium alloy material needs to be readjusted after the grinding is completed. It is not convenient to quickly adjust the direction of the magnesium alloy material after grinding the two sides, and it is not convenient to grind the four sides of the magnesium alloy material more quickly.

An annular groove is provided in the lifting seat 301 for the rotation and support of the rotating column 401. A pressure plate 402 is fixedly connected to the bottom of the rotating column 401, and a handle 403 is fixedly connected to the top of the rotating column 401. The handle 403 is L-shaped. A gear 404 is fixedly connected to the outer surface of the rotating column 401. A fixing component 5 is provided on the right side of the gear 404. The fixing component 5 includes an insert block 501, which meshes with the right side of the gear 404. A limiting rod 502 is fixedly connected to the right side of the insert block 501. A support piece 503 is movably provided on the outer surface of the limiting rod 502. The support piece 503 is fixedly connected to the top of the lifting seat 301. A second screw 504 is threaded through the right side of the support piece 503. The second screw 504 is rotatably connected to the right side of the insert block 501. A grinding component 6 is provided on the right side of the clamping assembly 3.

[0024] When the above-mentioned equipment is used, the magnesium alloy casting to be polished is first placed on the placement plate 2, and then the first screw 303 is rotated to drive the lifting seat 301 to descend on the support seat 302, so that the lifting seat 301 drives the rotating column 401 to descend, and the pressure plate 402 presses the magnesium alloy casting on the placement plate 2. At this time, both sides thereof can be polished.

An elastic arm 603 is fixedly connected to the left side of the sliding seat 602. The elastic arm 603 is arc-shaped and has a certain elasticity. A grinding device 604 is fixedly installed on the left end of the elastic arm 603. The number of the elastic arm 603 and the grinding device 604 is two, one front and one back.

The support plate 703 is fixedly connected to the top of the sliding seat 602.

[0027] When the above-mentioned device is used, when it is necessary to grind both sides of the magnesium alloy casting, the adjustment plate 701 is pulled by the electric push rod 702, and the adjustment plate 701 drives the two elastic arms 603 to open, so that the two grinding devices 604 are opened to accommodate the magnesium alloy casting. At this time, the electric slide rail 601 drives the sliding seat 602 to slide toward the magnesium alloy casting, so that the magnesium alloy casting is located between the two grinding devices 604. At this time, the electric push rod 702 pushes the adjustment plate 701, so that the adjustment plate 701 drives the two elastic arms 603 to close until the two grinding devices 604 clamp the magnesium alloy casting and the elastic arms 603 are deformed to a certain extent.
