Abstract
The invention discloses a locomotive traction motor axle suspension bush machining device, relates to devices for finish machining of an inner circle surface of an axle suspension bush of a locomotive traction motor, and mainly aims at solving the problems that due to the fact that an existing axle suspension bush is in the structure of two semi-circles, the existing axle suspension bush has certain deformation in a natural state after being machined so that the working performance of the existing axle suspension bush is affected, and the hidden danger of adhesion of the existing axle suspension bush and serious shaft locking in a running process can be caused. According to the locomotive traction motor axle suspension bush machining device, an upper tire body and a lower tire body form an inner cavity which is matched with the axle suspension bush in shape, one connecting edge of the upper tire body and one connecting edge of the lower tire body are connected through a hinge pin, the other connecting edge of the upper tire body and the other connecting edge of the lower tire body are fixedly connected through a bolt. Due to the fact that the closed space formed by the upper tire body and the lower tire body is in a hollow cylindrical shape and completely simulates an installing surface of the axle suspension bush of the locomotive traction motor, the axle suspension bush to be machined is installed in the inner circle surface formed by the upper tire body and the lower tire body in the machining process, and therefore the operation reliability of the axle suspension bush is improved, and the accidents of the adhesion of the axle suspension bush and the shaft locking in the running process are eradicated. The locomotive traction motor axle suspension bush machining device is simple to install, convenient to machine and capable of guaranteeing machining quality.
Description
Technical field
The present invention relates to a kind of locomotive traction motor axle suspension bush processing unit (plant), is mainly to the accurately machined locomotive traction motor axle suspension bush of locomotive traction motor axle suspension bush babbit inner headed face processing unit (plant).
Background technology
Usually the locomotive engine rotating shaft adopts rolling bearing or sliding bearing to connect with the suspension of car body, and the sliding bearing connection has the characteristics such as bearing capacity is high, and shock resistance is good, and stable working is reliable, and noise is little, and the life-span is long.It is widely used in the locomotive engine transmission system.Because the axle suspension bush bearing capacity of locomotive engine is larger, work under bad environment, start-up course is lubricated relatively poor, therefore the contact precision of the babbit alloy-layer of axle suspension bush and locomotive axle is very crucial, the quality of fit of axle suspension bush cylindrical and casing directly exerts an influence to shape and the operating accuracy of inner headed face, axle suspension bush is two semicircle structures simultaneously, there is certain distortion after processing under nature, these factors have directly affected axle suspension bush babbit inner headed face service behaviour, and its result causes sticking watt, the serious driving hidden danger of axle locking.
Summary of the invention
The objective of the invention is for distortion after axle suspension bush processing, with the contact precision impact on axle suspension bush babbit alloy inner headed face and wheel shaft such as the dimensional accuracy of casing contact precision, inner headed face, and a kind of rational in infrastructure, the easy-to-use locomotive traction motor axle suspension bush processing unit (plant) of proposition.
Technical solution of the present invention is: locomotive traction motor axle suspension bush processing unit (plant) is, formed the inner chamber that matches with the axle suspension bush shape by upper carcass and lower carcass, a fillet of upper and lower carcass connects by bearing pin, and another fillet is bolted to connection.
It is by steady pin, the fixed cover on upper and lower carcass to be linked together that a fillet of the upper and lower carcass described in technical solution of the present invention connects by bearing pin.
It is to be provided with vertically a steady pin at lower carcass that another fillet of upper and lower carcass described in technical solution of the present invention is bolted, along steady pin radially be fixed with a hold-down bolt, upper carcass by the pressing plate on it with fastening nuts on hold-down bolt.
Upper and lower carcass described in technical solution of the present invention is connected on lathe spindle by ring flange.
The present invention adopts the working condition of simulation axle suspension bush to process, and makes the fine finishining of axle suspension bush babbit inner headed face consistent with duty, so the working condition after the axle suspension bush assembling can keep comparatively desirable situation.The present invention adopts the hollow circle tube carcass of simulation axle suspension bush installed surface, and the cylinder carcass is divided into two semicircles in up and down, connects by shank and realizes free opening and closing.Use the present invention greatly to improve the functional reliability of axle suspension bush, stopped sticking watt, the serious driving accident of axle locking, reach the reliable purpose of axle suspension bush application safety.The installation of carcass simultaneously is simple, and the part that structure is convenient to process is installed, and can effectively improve the crudy of working (machining) efficiency and product.
