Mechanical hand for grabbing pistons

Abstract

The invention belongs to the field of mechanical automation, particularly provides a mechanical hand for grabbing pistons, and aims to solve the problems that engine piston assembly in an automation engine production line is high in cost and low in efficiency. The mechanical hand for grabbing the pistons comprises grabbing assemblies, driving assemblies and an outer shell, and is further provided with a push rod assembly, wherein the grabbing assemblies and the driving assemblies are rotatably connected with the outer shell; the driving assemblies are fixedly connected with the outer shell; the driving assemblies can drive the grabbing assemblies to rotate relative to the outer shell to grab or release the pistons; the push rod assembly is arranged in the middle of the four grabbing assemblies; and after the grabbing assemblies grab and place the pistons, the push rod assembly can knock the pistons. The mechanical hand has the advantages that the structure is simple and compact, the occupied space is small, driving depends on air power, pollution is avoided, the manufacturing cost is low, and the assembly quality is high.

Description

technical field [0001] The invention belongs to the field of mechanical automation and specifically provides a manipulator for grabbing a piston. Background technique [0002] At present, in industrial production, piston assembly is the most important and cumbersome part of an automobile engine. Due to the complex shape of the piston, it is difficult to grasp and operate, so it brings certain difficulties to the automatic assembly of the piston. [0003] At present, in general industrial production, single-degree-of-freedom manipulators with simple structures are used. This type of manipulator has a single function, and most of the objects that are grasped are regular-shaped objects. It is difficult to grasp objects such as pistons. Pistons in the automatic engine production line Assembling is still a manual operation. Therefore, the problems of high engine assembly cost and excessive workload of workers are particularly prominent. [0004] Correspondingly, a new manipulat...
