A double cylinder liner grabbing device

Abstract

The invention provides a grabbing device for double cylinder liners, which includes two sets of clamping arms, two sets of clamping blocks, a cylinder base and a cylinder; the cylinder is fixedly installed in the cylinder base, and the push rod of the cylinder is connected to The plate pushes the two groups of piston rods to slide back and forth in the two groups of clamping arms respectively; the two groups of clamping blocks are symmetrically installed inside the two groups of clamping arms, and the two ends of the clamping blocks pass through The first hinge and the second hinge are rotatably connected to the clamping arms; the bottoms of the two sets of clamping arms are equipped with anti-thrust mechanisms. The two sets of clamping blocks of the double-cylinder liner grabbing device are clamped inwardly at the same time to avoid excessive displacement of any one of the two cylinder liners to be grasped. Contact can effectively avoid crushing the inner wall of the cylinder liner; and after the grabbing is completed, the reverse thrust mechanism will rebound the partition to separate it from the cylinder liner; it not only ensures the stable operation of the grabbing system, but also prolongs the service life of the partition and reduces the Change frequency.

Description

technical field [0001] The invention relates to a cylinder liner grasping device, in particular to a double cylinder liner grasping device. Background technique [0002] In recent years, flexible production lines with joint robots as the core are becoming more and more widely used, which greatly reduces the dependence on labor, especially in the fields of automobile engine block casting, where inlays are often used in the production process. The process of the cylinder liner, the joint robot installed with the cylinder liner grabbing mechanism usually uses a single-hand gripper or a two-hand gripper mechanism driven by an ordinary gripper cylinder in the process of grabbing the cylinder liner. Because of structural limitations, the cylinder liner is often caught. Point contact (clamping in the form of scissors) causes damage to the inner wall of the cylinder liner; and the long-term use of the cardboard used to cut off each layer of the cylinder liner will form pits one by o...

[0002] In recent years, flexible production lines with joint robots as the core are becoming more and more widely used, which greatly reduces the dependence on labor, especially in the casting of automobile engine cylinders and other fields, where inlays are often used in the production process. The technology of cylinder liners, joint robots equipped with cylinder liner grabbing mechanisms usually use single-hand grippers or double-hand gripper mechanisms driven by common gripper cylinders in the process of grabbing cylinder liners, because structural limitations often cause cylinder liner grasping The inner wall of the cylinder liner is damaged due to the point contact of the picking part (clamping in the form of scissors); and the long-term use of the cardboard used to separate each layer of cylinder liner will form pits, so that when grabbing the two-piece cylinder at the same time During the process, it is easy to cause the sleeve cylinder to clamp the cardboard and move with the cardboard, causing the failure of the production line
