Problems solved by technology

[0003] At present, parallel robots mostly use link mechanisms, which have high coupling of each joint, high cost of parts processing, and high cost. At the same time, the high coupling between each joint also leads to the complexity of motion control, which brings great challenges to the popularization and application of parallel robots. great difficulty

Embodiment Construction

[0014] The present invention will be further described below in conjunction with the accompanying drawings.

[0015] Such as figure 1 As shown, a new two-degree-of-freedom parallel robot that mimics the human elbow joint includes: a base 001, an electric push rod assembly 002, and a working platform 003. It is characterized in that: the base 001 is used for the installation of various mechanisms, and the two sets of electric push rod assemblies 002 connect the base 001 and the working platform 003 in parallel through ball hinges at both ends.

[0016] Such as figure 2 As shown in the electric push rod assembly, the motor 005 is connected to the push rod 004. Through the control of the motor 005, the push rod 004 can be pushed to perform telescopic movement. The spherical hinges at the ends of the motor 005 and the push rod 004 are respectively connected to the base 001 Connect with working platform 003.

[0017] Such as image 3 As shown, the working platform 003 includes...

Abstract

The invention relates to a novel two-degree-of-freedom parallel robot imitating a human elbow joint, comprising: a base, an electric push rod assembly, and a working platform. It is characterized in that: the base is used for the installation of various mechanisms, the electric push rod assembly connects the base and the working platform in parallel through the ball hinges at both ends, and the working platform rotates orthogonally through two spherical hinges and one XY Two deep groove ball bearings on the shaft are in parallel with the base. The invention has high precision, convenient operation, freedom and flexibility, and low cost.

Description

technical field [0001] The invention discloses a novel two-degree-of-freedom parallel robot imitating a human elbow joint, and relates to the field of robot design. Background technique [0002] A parallel robot is a closed-loop mechanism driven in parallel with a moving platform and a fixed platform connected by at least two independent kinematic chains. The mechanism has two or more degrees of freedom and is mainly used for high-precision, high-speed assembly. Operation [0003] At present, parallel robots mostly use link mechanisms, which have high coupling of each joint, high cost of parts processing, and high cost. At the same time, the high coupling between each joint also leads to the complexity of motion control, which brings great challenges to the popularization and application of parallel robots. great difficulty. Contents of the invention [0004] In view of the defects existing in the prior art, the purpose of the present invention is to provide a novel two-...
