Abstract

The invention discloses a large-sized workpiece overturning device. Two parallel grooves are formed in a base, two stand columns are fixed above each groove, the four stand columns are arranged in an equidistant mode, chain wheels are fixed to the top ends of the stand columns and the two ends of the grooves respectively, closed-loop chains pass through the tops of the grooves and the tops of the stand columns and are meshed with the chain wheels, each chain becomes concave between the tops of the corresponding two stand columns, and a power device synchronously drives chain wheel and chain mechanisms to operate. A workpiece is hung on the chains, the angle of the workpiece can be changed through operation of the chains, human assistance is not needed, the large-sized workpiece overturning device is small in occupied space, safe and reliable, and production efficiency is significantly improved.

Description

technical field [0001] The invention relates to a large workpiece turning device, which belongs to the technical field of mechanical processing. Background technique [0002] When processing large workpieces, it is often necessary to flip the workpiece at a certain angle. For example, large workpieces with internal cavities, such as diesel engine body and large gearbox housing, need to clean the remaining machining chips from the inside of the workpiece in the middle of the two processing procedures, which is difficult to clean by hand alone. Usually, a crane is also used to lift the workpiece at a certain angle of inclination to dump it. If there is a dead angle in the internal cavity of the workpiece, it is difficult to pour it clean at one time, and it often needs to change different angles several times for pouring. In addition, when the processing surface of a large workpiece needs to be replaced, a crane is also used to lift the workpiece, and then change the angle o...
