Inner support grabbing and mold pressing manipulator for cylindrical inner wall workpiece

Abstract

The invention discloses an internal-shoring grabbing and cover die downward-pressing mechanical arm for cylindrical surface inner wall workpieces. The mechanical arm comprises an outer cylindrical sleeve and a grabbing device installed inside the sleeve. The grabbing device comprises a disk-shaped body matched with the sleeve, at least three internal-shoring mechanisms arranged on the disk-shaped body, and a telescopic linear motion driver which is installed on the disk-shaped body and is further connected with the internal-shoring mechanisms. The internal-shoring mechanisms comprise internal-shoring claws. The linear motion driver drives the internal-shoring claws to be opened and closed to be used for grabbing the workpieces. The lower end face of the sleeve is a precision-machined lower working face. By the adoption of the mechanical arm, the inner cylindrical surfaces of the workpieces can be grabbed and put down, the lower end face of the sleeve serving as a guide part of each internal-shoring mechanism can further be used as a pressure head for workpiece downward-pressing assembly, and the problem that a common mechanical arm can only transfer the workpieces without assembling the workpieces is solved.

Description

technical field [0001] The invention relates to the technical field of a manipulator in a material transfer section, in particular to an inner-supporting manipulator for grabbing and pressing down a cylindrical inner wall workpiece. Background technique [0002] For industrial production robots, feeding and unloading are the most basic functions, and the chucks required for different products are different. For cylindrical parts, external clamping chucks are generally used, that is, to clamp the workpiece from the outside of the workpiece, and these chucks mostly use three jaws to form a cylindrical hole to clamp cylindrical parts; for tubular parts , Generally, inner support chucks are used, but most of the inner support chucks only have the function of clamping and loosening the workpiece, and do not have the functions of auxiliary positioning and assembly. Contents of the invention [0003] In order to solve the above problems, the object of the present invention is to...
