Abstract

The invention relates to the technical field of piston processing, in particular to a flexible gripping mechanism for salt cores. The flexible gripping mechanism comprises a connecting flange, a three-jaw cylinder, a limiting press-putting assembly and a claw finger assembly. According to the flexible gripping mechanism for the salt cores, movement of fingers is limited by limiting blocks, clamping is soft, and the salt cores which are easy to break and low in strength and toughness are prevented from being damaged during clamping; the height of the limiting blocks on a center rod can be adjusted, so that the flexible gripping mechanism for the salt cores can be suitable for the salt cores of various specifications and sizes; and meanwhile, downward-press springs and downward-press platespress the salt cores, the salt cores are stable without moving and rotating when clamped, and the salt cores can be pressed into a mold and put in place when the salt cores are placed.

Description

technical field [0001] The invention relates to the technical field of piston processing, in particular to a salt core flexible grasping mechanism. Background technique [0002] With the development of the automobile industry, there are more and more types of internal cooling pistons, and the manufacturing process is becoming more and more complicated. The water-soluble salt core is made by pressing water-soluble salt as a matrix. Because it dissolves in water and is easy to remove the core, it is widely used in pistons with internal cooling oil passages. At present, due to the fragility of the salt core, the placement of the salt core during the piston casting process is generally done manually by workers, which is labor-intensive, the mold space is small, and the operation is inconvenient. At the same time, the stability of manual operation is poor, which may easily lead to uneven stress and damage to the salt core. In addition, since the salt core must be preheated to 5...
