Description

Technical Field

[0001] The utility model relates to the technical field of precision casting, in particular to a casting positioning device for precision casting. Background Art

[0002] Castings are metal objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with certain shapes, sizes and properties. Compared with the traditional sand casting process, the castings obtained by precision casting are more accurate in size and have better surface finish. After the castings are cooled and formed, they need to be polished, so positioning devices are used to clamp them.

[0003] For example, the utility model with application number CN202221942053.1 discloses a casting positioning device for precision casting. The utility model can drive the fixed plate to clamp the casting to the left and right through the cooperation between the adjustment component and the electric push rod, and can press the casting down to position through the clamping plate. At the same time, with the help of the anti-slip pad, the stability of positioning can be effectively improved. At the same time, under the action of the rotating component, it can drive the casting to flip and process the bottom, thereby improving work efficiency and facilitating use. However, after positioning, it can only be flipped vertically, so that multiple clamping is required during subsequent grinding, which increases the labor intensity of the staff.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a casting positioning device for precision casting is proposed. Utility Model Content
