Modular tool for machining PODPYATNIKOVOGO PLACES bolster freight car bogie

摘要

The invention relates to the field of machining recovered surfacing parts subject to wear of railway vehicles friction under repair production. Scope - repair shops and depots of rail transport. Precast tool for machining podpyatnikovogo place bolster freight car bogie consists of a metal body, the wedge clamps and mounting members for mounting of replaceable carbide cutting inserts, the mounting tongues for mounting the tool on the spindle and replaceable carbide cutting inserts. The design tool allows to produce synchronous machining of working surfaces podpyatnikovogo place following the dimensions and surface quality as required by drawing, fully repeating its shape, and also reduce the processing time is 1.5-2 times due to thrust one processing tool. The design of the instrument is compact, simple and easy to use, allows easy replacement of worn carbide cutting blades and provides the required processing on the drawing size, shape and quality podpyatnikovogo seat surfaces, and meets all the safety requirements of the operations.
