Compact machining and assembling device

Abstract

The invention relates to a compact machining and assembling device which comprises a barrel shell, a plurality of driving output branches, a middle sliding barrel, a cross shaft steering part, a motion platform and an end effector, the middle sliding barrel is arranged at the first end of the barrel shell in a sliding mode, and the driving output branches are evenly distributed in the barrel shell; the cross shaft steering part is arranged on the steering connecting part through a second connecting rod and connected with the motion platform through a motion platform mounting base, and an end effector is arranged in the middle of the motion platform. By arranging the middle sliding barrel, the middle sliding barrel can bear torque generated in the machining and assembling process, the moving precision of the end effector can be improved, meanwhile, the middle sliding barrel is pushed outwards through the air spring, pre-tightening force is applied to the tail end of the device, and the machining precision or assembling accuracy of the end effector is effectively improved; and in addition, pipelines and wire rods required by working of the end effector can be stored in the drag chain and the middle sliding barrel, so that the structure of the device is more compact.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing and assembly, in particular to a compact processing and assembly device. Background technique [0002] With the intelligent development of manufacturing, intelligent manufacturing technology has gradually become one of the indicators for evaluating a country's industrial manufacturing level. Automobile, aviation and other large-scale equipment manufacturing fields have more and more urgent demands for automatic processing and assembly precision, such as drilling and hammer riveting of large aircraft parts, grinding and deburring of automobile wheels, engine blocks and other components. The disadvantages of the traditional tandem manipulator are the large cumulative error and insufficient joint stiffness. In order to ensure the motion accuracy of the end effector, the body volume of the manipulator must be increased, resulting in a large space occupation. Therefore, a compact processi...

Problems solved by technology

[0003] In view of the above situation, the present invention provides a compact processing and assembling device, which solves the problems of insufficient rigidity of the traditional mechanical arm and the large space occupied by the body, and slides through the guide groove on the outer wall of the middle sliding cylinder and the guide block on the inner wall of the housing. The combination enables the middle sliding cylinder to withstand the torque generated during the processing and assembly process, which is beneficial to improving the movement accuracy of the end effector. At the same time, the middle sliding cylinder is pushed out through the gas spring to apply pre-tightening force to the steering structure, which effectively improves the device. Rigidity of the end, thereby improving the machining accuracy or assembly accuracy of the end effector
