Description

Technical Field

[0001] The utility model relates to the technical field of polishing and grinding machines, in particular to a polishing device for columnar aluminum castings. Background Technique

[0002] Aluminum castings refer to equipment devices made of pure aluminum or aluminum alloy by means of casting. Generally, sand molds or metal molds are used to pour molten aluminum or aluminum alloy into the mold cavity, and various shaped and sized aluminum parts or aluminum alloy parts obtained are usually called aluminum die castings.

[0003] When the aluminum casting is cast, a grinding machine is needed to polish the surface of the material. However, when the existing grinding machine is in use, the operator needs to hold the material by hand and place it on the grinding machine. And during the grinding process, the material will jump and shift. To prevent the jumping and deviation, the operator needs to hold and press it for a long time. For this reason, we propose a polishing device for columnar aluminum castings to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a polishing device for columnar aluminum castings.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A polishing device for columnar aluminum castings includes a grinding machine frame. Above the grinding machine frame, a grinding head is installed. And on the side of the grinding head, a material guiding groove is installed. Above the material guiding groove, a fixed gantry is arranged. And inside the fixed gantry, a pressing mechanism is inserted. Below the pressing mechanism, a guiding mechanism is installed. Inside the pressing mechanism, a limiting mechanism is inserted.

[0007] Preferably, the pressing mechanism includes a pushing screw. The pushing screw is threadedly inserted above the fixed gantry. And below the pushing screw, a pressing plate is connected through a bearing. By threading the pushing screw with the fixed gantry, when the pushing screw is rotated, the pressing plate can be pushed to move.

[0008] Preferably, on both sides above the pressing plate, guide columns are fixedly connected. And the guide columns are cylindrical. Inside the fixed gantry, circular holes adapted to the guide columns are opened. By setting the guide columns to be cylindrical, the wear between them and the fixed gantry can be reduced.

[0009] Preferably, the guiding mechanism includes a fixed block. The fixed block is fixedly connected below the pressing plate. And inside the fixed block, a guiding pressure roller is installed. The guiding pressure roller can facilitate the guiding of the material.

[0010] Preferably, the limiting mechanism includes an adjusting rod inserted into the pressing plate, and a limiting baffle is fixedly connected to the outer end of the adjusting rod. The distance between the limiting baffles can be conveniently adjusted through the adjusting rod.

[0011] Preferably, two adjusting rods are diagonally inserted into the pressing plate, and teeth are provided on the opposite sides of the two adjusting rods. A gear is installed at the central position inside the pressing plate, and the gear meshes with the two adjusting rods. Through the teeth provided on the opposite sides of the two adjusting rods, the gear can drive the two adjusting rods to move synchronously.

[0012] Preferably, a limiting stud is fixedly connected to the outer end of one of the adjusting rods. A strip-shaped through groove adapted to the limiting stud is opened on the outer side of the pressing plate. A moving nut is threadedly sleeved on the outer end of the limiting stud, and a limiting disc is fixed to the end of the moving nut. By rotating the moving nut, the moving nut can move along the surface of the limiting stud, and the moving nut drives the limiting disc to abut against the surface of the pressing plate, facilitating the function of limiting the adjusting rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. The device can guide columnar materials to move into the grinding head for grinding through the material guiding groove, and the pressing plate can be pushed to move by rotating the pushing screw rod. When the pressing plate drives and presses on the surface of the material, it can effectively prevent the material from jumping during polishing and grinding, affecting the polishing effect, and at the same time, it can avoid manual pressing by people when polishing the material.

[0015] 2. By rotating the moving nut of the device, the limiting disc can be moved away from the surface of the pressing plate. At this time, by pulling the limiting baffle, the adjusting rod can move inside the pressing plate, and the two groups of limiting baffles can move relative to each other through the gear, effectively facilitating the adjustment of the distance between the two groups of limiting baffles and facilitating the blocking of both sides of materials of different sizes.
