Abstract

The invention relates to a mechanical arm suitable for a large workpiece, in particular to a mechanical arm suitable for automatic sand blasting of a large workpiece. The mechanical arm is characterized by comprising an overlapped framework based on the principle of a rope arrangement system; and the central part of the framework is provided with a through shaft rack guide rail driven by a motor and a speed reducer outside the framework. The mechanical arm provided by the invention has a unique structure and long service life, and can be applicable to products with diameter being about 2m, wherein the exit pressure of a spray gun is 6MPa.

Description

technical field [0001] The invention relates to a mechanical arm suitable for large workpieces, in particular to a mechanical arm suitable for automatic sandblasting of large workpieces. Background technique [0002] At present, all the researches in the world are high-precision precision manipulators. The price of a manipulator is about 200,000, and a sandblasting room needs 5 manipulators to achieve effective sandblasting. In this way, the cost is 1 million, which is too high. The precision of the manipulator is high, and the maintenance of such ultra-high-precision equipment is more complicated, and the sand ejected by the sandblasting machine will often cause the manipulator to be stuck, resulting in increased maintenance and repair costs; currently there is no automatic sandblasting for large workpieces. robotic arm. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art and provide a mechanical arm suitab...
