Embodiment Construction

[0023] The motors on the upper and lower sides of the bracket realize the sliding block 1-9 moving up and down on the screw mandrel 1-3 along the guide rail 1-4 through the speed coordination. The upper arm 4-1 of the elbow joint is connected with the slide block 1-9 with a connecting rod. Therefore, the elbow joint upper arm 4-1 and the slider 1-9 remain relatively stationary, and move up and down together with the slider 1-9. The lower arm 4-3 of the elbow joint is connected with the upper arm 4-1 of the elbow joint by pin shafts 4-4 and 4-2 needle bearings, and the lower arm 4-4 of the elbow joint moves up and down as the upper arm 4-1 of the elbow joint moves around the pin Axis 4-4 rotates freely. The lower arm 4-4 of the elbow joint is connected with the ball joint rod 8 with a connecting rod, and the other spherical end of the ball joint rod is connected with the robot elbow 6 in the form of a spherical pair. The ball joint moves in space with the planar movement of t...

Abstract

A six-degree-of-freedom robot arm carving machine capable of realizing planar carving, stereo embossments and three-dimensional carving consists of a support and three rotor arms identical in structure. Each robot arm is a two-degree-of-freedom mechanism formed by sequentially connecting a rotary pair, a moving pair, a rotary pair and a ball pair. Each robot arm is driven and controlled by an upper motor and a lower motor to realize six-degree-of-freedom spatial motion of a movable platform to drive a carver to move according to a preset path for caving.

Description

Technical field [0001] The utility invention relates to a motion simulation of a novel robot mechanism, which realizes free movement on six degrees of freedom through the control and cooperation of different mechanical parts, thereby driving a carving knife to realize two-dimensional and three-dimensional carving. Background technique [0002] Parallel robots have excellent characteristics such as simple structure, good rigidity, high positioning accuracy, and fast dynamic response, which make up for the shortcomings of series robots, and are especially suitable for occasions with high precision, large loads and small working spaces. It has broad application prospects in mechanical processing, military and other fields. Therefore, it has important theoretical significance and practical value to conduct a comprehensive and systematic research on it and push it to practical application. At present, in recent years, it has become a hot spot in the field of robot research, and ...
