[0002] The mechanical workpiece is a single piece that makes up the machine and its inseparability. It plays an important role in the automation industry. The mechanical workpiece includes the connection of parts, the supporting parts, the lubricating lubrication system and the sealing Components, the components of the transmission system that transmit motion and energy, in the process of processing mechanical workpieces, generally use CNC milling machines to finish the mechanical workpieces, and according to the needs of mechanical workpiece processing, they need to be placed on the processing platform The workpiece is rotated so that the milling machine can process the workpiece conveniently. The existing method is generally to rotate the workpiece separately after one side of the workpiece is processed, and the processing platform on which the workpiece is placed does not rotate, so the workpiece is rotated During the process, since there are many workpiece clamping mechanisms on the processing platform, it is necessary to loosen the clamping mechanisms one by one, and use the lifting tool to lift and rotate the workpiece and place it on the processing platform again, and then use the clamping mechanism to lift the workpiece Fixing, the labor intensity of the workers is high, the work efficiency of workpiece processing is low, and in the process of rotating large workpieces, there will often be large deviations in the rotation angle of the workpiece, which will affect the efficient and accurate processing of the workpiece , the existing workpiece rotation device has a complex structure and troublesome operation. It is generally only suitable for processing small workpieces, and it is difficult to fix and rotate larger workpieces. As a result, large workpieces cannot be processed efficiently and accurately, and cannot meet the needs of production.

[0003] The invention patent with application number 200910062924.3 provides a workpiece rotating device, which includes equipment frame, lifting cylinder and mounting plate. The lifting cylinder is connected with the equipment frame through the fixing plate. It is connected to the compression rod through the connecting frame. Rollers are installed at both ends of the compression rod. The rotating cage is located under the mounting plate. The two ends of the rotating cage are connected to the limit guide rail through the rotating shaft. The position of the rollers at both ends of the pressing rod corresponds to the limit guide rail, and the rotating drive device is connected to the rotating shaft through the transmission mechanism. However, the fixing mechanism of the device is single, and it is difficult to efficiently fix workpieces of various specifications, and the workpieces are rotated during rotation. The stability is poor, it is difficult to meet the needs of workpiece processing
