Summary of the invention
The purpose of this utility model provides the runner plate milling apparatus of a kind of suitable scene to the plane lapping of large-scale ring-type runner plate.
To achieve these goals, the technical scheme that the utility model is taked is: a kind of runner plate milling apparatus, comprise that one has the bracing frame I of hollow base, lifting and rotating driving device, grinding assembly and lapping liquid adding set, lifting and rotating driving device comprise rotating driving device that is slidingly connected with bracing frame II and the lowering or hoisting gear that connects with bracing frame II activity, keep in touch the output shaft I top of lowering or hoisting gear and the bottom of rotating driving device, grinding assembly comprises a horizontal rotary arm, abrasive disk rotates with erection support and connects, erection support and horizontal rotary arm are slidingly connected, the abrasive disk working face upwards, rotating shaft and horizontal rotary arm are fixedly connected, the output shaft II of rotating shaft and rotating driving device passes through splined, rotating shaft axial line and annular work piece central lines, the nozzle of lapping liquid adding set is positioned near the abrasive disk, and the position sensor that is fixed on the bracing frame I is positioned near the abrasive disk top.
Above-mentioned runner plate milling apparatus, lifting and rotating driving device are connected by straight line oil cylinder and rotary hydraulic motor and form, being connected into and out of hydraulic fluid port and hydraulic means employing high-pressure hose of lifting and rotation combination driving device.
Above-mentioned runner plate milling apparatus, abrasive disk adopts the Birmasil manufacturing, and working face has certain some grooves.
Above-mentioned runner plate milling apparatus, abrasive disk working face have ring-type and symmetrical rounded trenches, and the central area is a circular groove.
Because adopt said structure, annular work piece is fixed on the bracing frame I, the abrasive disk working face upwards so the utility model can carry out runner plate grinding work at the maintenance scene, has been avoided the tediously long duration of depot repair; The runner plate assembly does not need the operation of overturning, and has reduced security risk; Abrasive parameters is adjustable, improves runner plate and grinds effect and quality; Automatically add lapping liquid, reduce maintenance worker's labour intensity.
