Description

Technical Field

[0001] The utility model belongs to the technical field of casting production, and particularly relates to an automatic surface treatment device for precision castings. Background Art

[0002] When precision casting is performed through a mold, if there are defects on the surface of the casting, it needs to be polished before it can be used as a finished product. At present, the post-polishing of some precision castings is mostly done by staff using handheld polishing guns, but the shapes and sizes of castings vary. When the staff polish the castings, it is not convenient to control the force and the polishing accuracy. Therefore, an automatic surface treatment device for precision casting castings is needed to automatically polish the castings and improve the surface quality of the castings.

[0003] According to the search, the announcement number CN219853786U is an automatic grinding device for the arc surface of precision castings. The device drives the limit plate to clamp the casting through the threaded rod, and then drives the precision casting on the pad to rotate by the driving motor. At the same time, the sliding rod moves in a circle in the through hole opened in the processing table. At this time, the height of the grinding disc is changed according to the size of the precision casting by controlling the first electric telescopic rod, and the two second electric telescopic rods cooperate with the rotating shaft and the movable shaft to change the angle at which the grinding disc grinds the casting; at the same time, the suction head cooperates with the bending tube to extend to one side of the precision casting, and the vacuum cleaner sucks the debris and dust generated during grinding into the storage box through the bending tube, and collects them through the filter; but the debris and dust will accumulate and remain on the filter. If you want to clean the filtered debris and dust, you can only disassemble and replace the filter after stopping the machine;

[0004] A precision casting grinding device with announcement number CN220348059U fixes the casting by fastening screws and fastening blocks, then the electric push rod and the second drive motor cooperate with the grinding disc to grind the casting, and the first drive motor controls the first rotating shaft to drive the clamping frame to rotate, thereby turning the casting over so that the grinding disc can grind the other side of the casting, and at the same time the water pump draws water from the water storage tank into the connecting pipe and finally sprays it out from the spray pipe to clean the surface of the precision casting, and the waste water and waste chips after cleaning are filtered through the filter net, and the filter net can be taken out for cleaning, and the filtered water falls into the water storage tank through the lower funnel for recycling; but the clamping mechanism in the device is difficult to clamp and fix special-shaped castings;

[0005] Therefore, there is a need for an automated surface treatment device for precision castings, which can clamp special-shaped castings while continuously cleaning the filter screen when the equipment is operating normally. Summary of the invention
