Turnover device for large workpiece

Abstract

The invention provides a turnover device for a large workpiece. The turnover device comprises a girder, a frame, a lifting mechanism, a guide mechanism and a turnover mechanism; the two ends of the girder are fixedly connected with the turnover mechanism correspondingly; the turnover mechanism is fixedly mounted on the lifting mechanism; the lifting mechanism is positioned at the middle part of the frame and is rotatably connected with the frame; the two ends of the lifting mechanism are fixedly connected with guide mechanisms; the guide mechanisms wrap the frame inside; the turnover mechanismcomprises a first motor, a turnover assembly and a turnover connector; the first motor is positioned on the upper plane of the lifting mechanism and is fixedly connected with the lifting mechanism; the first motor is fixedly connected with the turnover assembly; the turnover assembly is fixedly connected with one side of the turnover connector; and the other side of the turnover connector is fixedly connected with the girder. The turnover mechanism is fixedly connected with the girder through a rotary bearing, and the turnover moment of the rotary bearing is relatively high, so that a large radial load can be borne, and the turnover device is suitable for the turnover of the large workpiece.

Description

technical field [0001] The invention relates to the technical field of turning machines, in particular to a turning device for large workpieces. Background technique [0002] In the process of industrial production, each equipment or workpiece needs to be inspected. Small equipment or workpieces can be manually turned over for inspection, but large workpieces or equipment cannot be manually turned over for inspection, which makes the efficiency low. Therefore, in the inspection process of large workpieces , the overturning machine is particularly important, for example: patent "CN206357182U" discloses a lifting and overturning mechanism, through the pulley on the top of the frame, the upper bastard bypassing the pulley and the winch at the bottom to lift the vertical slide seat, the vertical slide The guide column is connected to the seat. By avoiding the vertical slide seat from falling, a bearing seat is arranged in the vertical slide seat. The bearing seat runs through th...

Problems solved by technology

[0003] In order to overcome the following problems in the prior art, the traditional turning machine is suitable for small workpieces, which has high requirements for space, the guide mechanism is easily damaged, and the torque at the end of the rotating shaft is relatively small, and it is easy to turn over large and heavy workpieces. The fracture of the shaft end will affect the stability and safety of the turning machine
