Double-ball joint telescopic six-dimensional parallel forging operation machine

Abstract

The double-ball joint telescopic six-dimensional parallel forging operation machine consists of six identical fixed ball joints, six identical hydraulic cylinders, six identical dynamic ball joints, one claw beam platform, one clamp, one upper platform, and six sets of identical uprights. The six sets of identical uprights are configured symmetrically on the large walking chassis, and each of the upright set is connected to one hydraulic cylinder via one fixed ball joint, the hydraulic cylinder is then connected via one dynamic ball joint to the claw beam platform, these six dynamic ball joints are configured symmetrically on the large walking chassis in the mode corresponding to that of the six upright sets, and the clamp for grasping forging is mounted onto the claw beam platform. The present invention utilizes six hydraulic cylinders for great tonnage operation force and six operation motion, and realizes the multiple bearing operation of large forging at low cost.

Description

technical field [0001] The invention relates to a double-spherical hinge telescopic six-degree-of-freedom parallel forging manipulator, which is used for grabbing and operating forging blanks during free forging, and belongs to the field of forging processing in mechanical engineering. Background technique [0002] The forging manipulator is one of the basic tools for large-scale forging pressure processing, and it is used in conjunction with the press. The current forging manipulators include wire rope suspension type, multi-bar mechanism combined type, etc. The wire rope suspended forging manipulator has a small operating capacity and is used for small-scale forging, while the multi-bar mechanism combined forging manipulator has a large operating capacity and is used for large-scale forging. Generally speaking, the forging operation functions that the forging manipulator needs to realize include jaw clamping, tong bar rotation, tong bar lifting, tong bar pitching, tong ba...

AI Technical Summary

Problems solved by technology

In the forging manipulator of this patent, during the forging process, the retraction action of the clamp required by the extension and deformation of the forging is completely realized by the walking of the cart, which has a huge moment of inertia, consumes a lot of energy, and is relatively difficult to control; The four actions of pitching, tong bar lateral movement, and tong bar swing are realized by different mechanisms. The structure is complex, the number of parts is large, and the manufacturing cost is high. Moreover, the tonnage of the forging manipulator is small, and it is only suitable for small and medium-sized forging processes.

Through literature search and analysis, the movements of the current forging manipulator, such as lifting and lowering of the forging manipulator, pitching of the tong bar, lateral movement of the tong bar, and swinging of the tong bar, are all realized by combining different mechanisms. The structure is complex, the number of parts is large, and the manufacturing cost is high. And they are all small forging manipulators with low operable tonnage
