Problems solved by technology

[0002] In the prior art, the overturning method of large mechanical parts is to use two hooks to lift and overturn in the air. Due to factors such as the large tonnage, weight and shape of the workpiece, bumps and scratches are often caused on the spreader and the workpiece during the overturning process accidents, the safety factor is low, and large mechanical parts are easy to move on the flip frame during flipping, which poses hidden dangers to the personal safety of workers. When large flipping machines flip large mechanical parts, sometimes Large mechanical parts will also be rotated for easier operation; in addition, this is not only labor-intensive, inefficient, but also has a very low risk factor, resulting in a significant increase in production costs

Abstract

The invention discloses a 360-degree large part turnover device and a working method thereof. The 360-degree large part turnover device is composed of a rotary motor, a belt wheel, a material to be turned over, a turnover rotor, a turnover rotary shaft, supporting side plates and a controller. The number of the supporting side plates is two, and the rotary motor and the controller are arranged on the two sides of the bottom ends of the supporting side plates correspondingly. The belt wheel is connected to the rotary motor and fixedly connected with the supporting side plates. The turnover rotary shaft is arranged at the tops of the supporting side plates and penetrates the supporting side plates. The turnover rotor is arranged on the turnover rotary shaft. The material to be turned over is located in the turnover rotor. The 360-degree large part turnover device is large in turnover angle, stable in structure and easy to operate, the turnover work of parts is achieved conveniently and safely in a labor saving manner, and the defects of bumping, scratching and the like caused during manual operation are effectively avoided. The device achieves multiple purposes, the production efficiency is improved, and the labor intensity of operators is reduced.
