Description

Technical Field

[0001] The invention belongs to the technical field of casting processing, and in particular relates to a surface grinding device for castings. Background Art

[0002] Casting is a metalworking process that involves pouring molten metal into a pre-prepared mold and waiting for it to cool and solidify to form metal parts of the desired shape and size. Casting processes are mainly divided into sand casting, metal mold casting, investment casting, pressure casting, centrifugal casting, continuous casting, etc., and are widely used in the production of workpieces with complex shapes such as steel, non-ferrous metals, and alloys.

[0003] A Chinese invention patent with publication number CN113681416A discloses a grinding device suitable for special-shaped castings, including a processing table, a rotating clamping seat is installed on the processing table, and rough grinding components consisting of groove wheels and grinding belts are symmetrically installed on the left and right sides of the processing table. A fine grinding component with an adjustable angle is installed at the front end of the processing table through a base. The device has two grinding processes. In conjunction with the rotation of the casting on the rotating clamping seat, the grinding belt performs preliminary grinding on the surface of the casting to remove defects such as burrs that are more obvious and larger on the surface, and then a secondary fine grinding is performed through the grinding piece with an adjustable angle to further improve the grinding effect. However, the device still has some shortcomings. No matter it is the initial or secondary grinding, there is a lack of necessary pressure device between the grinding belt and the casting, which causes the grinding belt to contact the casting only by its own tension force. The pressure required for grinding is insufficient, resulting in the grinding effect being less than expected or the grinding time being longer, affecting work efficiency. In addition, the fine grinding component cannot be adjusted in all directions, resulting in the inability to grind 360° of the casting surface in one clamping. If you want to grind comprehensively and thoroughly, you need to clamp it manually multiple times, which greatly reduces work efficiency.

[0004] Therefore, in view of the above-mentioned deficiencies, the present application proposes a surface grinding device for castings that can effectively solve the above-mentioned problems. Summary of the invention
