A multi-section three-parallel mechanism mechanical arm device that can realize automatic retraction

Abstract

A multi-section three-parallel mechanical arm device capable of realizing automatic retraction relates to the technical field of mechanical arms. The invention solves the problem that the existing mechanical arm mostly adopts multi-axis series mechanism, which has the limitation of slow movement and inability to provide large torque. The two guide rails of the present invention are relatively arranged between the front support and the tail support, two racks are oppositely arranged on the inner walls of the guide rails on both sides, and two support webs are relatively arranged between the upper support plate and the lower support plate In between, the servo hydraulic cylinder is installed on the shell of the power cabin, the execution ladder shaft is installed on two support webs, the execution gear installed at both ends of the execution ladder shaft meshes with the racks on both sides, and the servo hydraulic cylinder connector is installed on the front seat Above, the connecting piece of the servo hydraulic cylinder is connected with the piston rod of the servo hydraulic cylinder, and the main body of the extended arm passes through the mechanical arm of the front support to connect with the front seat through the hole. The present invention can ensure the quickness of the overall movement of the mechanical arm, and can also ensure the required torque when grasping large-mass objects.

Description

technical field

[0001] The invention relates to the technical field of mechanical arms, in particular to a multi-section three-parallel mechanical arm device capable of automatic retraction. Background technique

[0002] The robotic arm is an important industrial device, which is widely used in industry, aerospace, military, medical, service and other fields. The robotic arm can be used to grasp and release large-mass objects, and plays a very important role in industrial production. important role. Traditional robotic arms mostly use multi-axis series mechanisms. This solution has a simple structure and is easy to operate and control, but it has the problem of slow movement and the limitation of not being able to provide a large torque. Contents of the invention

[0003] The purpose of the present invention is to solve the problem that the existing mechanical arm mostly adopts multi-axis series mechanism, which has slow movement and cannot provide a large torque limit, a...
