Multi-axis numerical control mechanical claw based on parallel mechanism

Abstract

The invention relates to the field of mechanical claws, in particular to a multi-axis numerical control mechanical claw based on a parallel mechanism. The multi-axis numerical control mechanical claw comprises a grabbing structure, a parallel rotating structure and a packaging shell, wherein the bottom of the parallel rotating structure is rotationally connected with the packaging shell, a mechanical claw angle adjusting cavity is formed in the packaging shell, an angle control structure is arranged in the mechanical claw angle adjusting cavity, and the bottom end of the angle control structure is hinged to the grabbing structure; and the grabbing structure comprises a first fixing plate, a first rotating rod, a second rotating rod, a second fixing plate, a third rotating rod, a clamping plate, fixing rods, a third fixing plate, a first motor 19 and a lead screw 191, and the top ends of the four fixing rods are in threaded connection with the bottom of the third fixing plate. The angle control structure and the rotating structure are arranged at the bottom of the parallel rotating structure, so that the rotating angle of the parallel rotating structure is increased, the mechanical claw can be applied to more working scenes, and the sensitivity of the mechanical claw is effectively improved.

Description

technical field [0001] The invention relates to the field of mechanical claws, in particular to a multi-axis numerically controlled mechanical claw based on a parallel mechanism. Background technique [0002] The manipulator is the earliest industrial robot. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect personal safety. Therefore, it is widely used in machinery manufacturing and light industry and other departments. With the advent of more and more micro-devices, the traditional six-axis manipulator is difficult to complete the precision machining of many micro-devices due to its large footprint, large work delay, and large inertia; manipulators generally adopt a parallel structure, which is Because the parallel structure occupies a small volume and requires few parts, but the parallel structure has a defect that its working space is limited. When the parallel structure i...

Problems solved by technology

It solves the problem that the gripping range of the manipulator is small, and the mechanical moving parts are easily affected by dust adhesion, causing lubrication failure and affecting the gripping work of the mechanical claws
