Turnover machine

Abstract

The invention provides a turnover machine comprising a turnover body. The middle part of the turnover body is provided with a through hole for containing a piece to be turned over; at least two sliding positioning plates are oppositely arranged at the edge of the through hole; an air cylinder for driving each sliding positioning plate to slide towards the center of the through hole is fixedly arranged corresponding to each sliding positioning plate; a driving shaft and a driven shaft are respectively fixedly arranged at the side face of the turnover body; the driving shaft passes through a bearing seat arranged on a primary supporting seat to be connected with an output shaft of a driving device; and the driven shaft is arranged in the bearing seat of a secondary supporting seat in a penetrated manner. The turnover machine disclosed by the invention solves the problem in the prior art that wheels of a railway locomotive and a vehicle are difficult to turn over, eliminates potential safety hazards caused by manual operation in the prior art, improves the production efficiency and is more adapted to the requirements of modern production.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a turning machine. Background technique [0002] During the manufacturing process of railway locomotive wheels and railway vehicle wheels, due to the requirements of the processing process, frequent turning is required. However, the diameter of the wheel of a railway locomotive or vehicle is more than 1250mm, the weight of the blank is about 1000kg, and the weight of the finished product after processing can reach 730kg. The overturning of such large-volume and heavy-weight parts is a problem faced in the manufacturing process. [0003] figure 1 It is a structural diagram of a railway locomotive wheel. Please refer to figure 1 , the commonly used methods for turning over railway locomotives and vehicle wheels in the prior art mainly include: one is to set up a supporting block 11 under the wheel 1 to make the wheel 1 in an inclined state, and use nylon ropes to penetrat...
