Description

TECHNICAL FIELD

[0001] The utility model relates to metal casting processing technical field, concretely is a kind of grinding device for metal casting processing. BACKGROUND

[0002] Metal casting is the process of melting metal into liquid that meets certain requirements and pouring it into a mold, and after cooling, solidification, cleaning and processing, a casting with predetermined shape, size and performance is obtained. The casting blank is almost shaped, so mechanical processing or a small amount of processing is not needed, which reduces cost and time to some extent. Casting is one of the basic processes in modern mechanical manufacturing industry. The surface of the metal casting is not smooth after casting, so the surface of the metal casting needs to be polished.

[0003] The patent document with publication number CN221088440U discloses a polishing and clamping device for metal casting processing, which includes a support column and a workbench. The workbench is fixedly connected to the upper end of the support column. A support frame is fixedly connected to the upper side of the rear end of the workbench. A first air cylinder is fixedly connected to the front end position of the lower side of the support frame. A polishing mechanism is connected to the upper end of the workbench. When using the device, the metal casting to be polished is placed on the upper end of the support plate, then the handle is rotated to drive the threaded rod to rotate and move the pressing plate to the upper end of the metal casting. Then the first air cylinder and the polishing machine are started to drive the polishing head at the lower end of the polishing machine to polish the surface of the metal casting. At the same time, the fan is started to blow the metal debris generated during polishing into the air pipe, and then through the through hole into the filter screen below the collection frame to be collected. However, the existing technology still has defects:

[0004] (1) The existing device only clamps and fixes the metal casting from two sides and the upper and lower ends. For flat metal castings, the stress direction changes during the turning process, and the metal casting has a risk of falling, which can cause damage to the metal casting. Moreover, the pressing plate is adjusted by rotating the threaded rod to clamp the metal casting, which often requires many rotations to start clamping and fixing. When the metal casting needs to be adjusted or quickly adjusted due to misalignment, the adjustment is very inconvenient, which reduces the polishing efficiency of the metal casting.

[0005] (2) Although the existing device can change the polishing angle of the metal casting, it is not convenient to adjust the horizontal position of polishing. When multiple positions on the surface of the metal casting need to be polished, the metal casting needs to be repeatedly disassembled and re-fixed, which reduces the polishing efficiency of the metal casting.
