Background
The bearing bush is widely applied to marine diesel engines, particularly high-power diesel engines, the radius range of the inner hole of the bearing bush is larger than R500mm, and the problems of inconvenient operation and the like exist in the prior art. Generally, a bimetal material compounded by an aluminum base or a copper base and steel is adopted, a rotating shaft for the existing feeding is a horizontal shaft, the feeding is inconvenient, and the adjustment is needed. The surface of the bearing bush needs to be subjected to a series of treatments such as cutting, rolling, strengthening, bending and the like.
In the bearing bush machining industry, with the improvement of automation degree, different devices such as a boring machine and chamfering devices are often connected through a conveying belt so as to improve production efficiency. In fact, the prior art has been able to adapt the front and rear machines to integrated transport. However, in the machining process, the bearing bush faces leftwards after the front machine such as a boring machine is machined, and when the bearing bush enters a rear machine such as chamfering equipment, the machining requirement is that the bearing bush enters the equipment in a state of facing rightwards, the turning process can be finished only manually at present, and because the production capacity of the bearing bush is large, the process greatly increases the labor capacity and reduces the production efficiency. CN201320804939.4 a conveying device for automatically steering bearing bushes provides a conveying device, but it cannot meet the requirement of automation.

Although the CN201020289599.2 milling bearing bush oil groove device provides a processing scheme, the device cannot meet the processing modes of various oil grooves, and has poor universality and high cost. When the punch head punches the positioning lip of the bearing bush in the prior art, the bearing bush is easy to damage, and the punch head is easy to break. CN201020289581.2 is a milling device before punching a bearing bush positioning lip, but the defect of low processing precision still exists. In the CN201910643763.0 bearing bush processing system, the feeding part is easy to loosen, a deviation correcting mechanism is needed, and the feeding of a bearing bush piece is inconvenient; the transmission assembly has single function and cannot effectively utilize the transmission time; the single component assembly is manufactured, and the bending assembly is poor in effect, large in deformation and easy to rebound; pairing stations and difference of transmission lines; the excircle assembly is machined, and turning is inconvenient; machining the inner hole assembly with inaccuracy; the processing lip subassembly, the whereabouts is low, and the memory space is inconvenient.
