Tool for machining inclined holes of force measuring wheel set of steel rail flaw detection car

Abstract

The invention belongs to the technical field of machining and manufacturing of a force measuring wheel set of a subway steel rail flaw detection car. The tool for machining inclined holes of the force measuring wheel set of a steel rail flaw detection car comprises two supporting piers, pressing plates and wedge blocks, the two supporting piers are arranged in a left-and-right correspondence mode, two supporting rollers are correspondingly arranged on each supporting pier, and two ends of a shaft of the force measuring wheel set are separately placed between the two supporting rollers in a matching mode; the pressing plates are correspondingly arranged above the supporting piers in a matching mode, and the pressing plates and the supporting piers are connected and fixed through long screw rods in a tensioning mode, and the force measuring wheel set is fixedly arranged between the pressing plates and the supporting rollers in a matching and pressing manner; and the number of the wedge blocks is two, and the two wedge blocks are separately and oppositely arranged below wheel bodies of the force measuring wheel set in a wedging mode. According to the tool for machining the inclined holes of the force measuring wheel set of the steel rail flaw detection car, the requirement for manufacturing precision of the subway steel rail flaw detection car force measuring wheel set can be met, the working efficiency is greatly improved, the tool is more reliable in the whole assembling process, positioning and supporting of the force measuring wheel set can be effectively realized.

Description

technical field [0001] The invention belongs to the technical field of processing and manufacturing a force-measuring wheel set of a subway rail flaw-detecting vehicle, and in particular relates to a tool for processing inclined holes in a force-measuring wheel set of a rail flaw-detecting vehicle. Background technique [0002] The force measuring wheel set of the subway rail flaw detection vehicle is the key part of the subway rail flaw detection vehicle, and it is the main body of the dynamic test of the rail flaw detection vehicle. After the assembly of the entire wheel set is completed, the elongated hole that runs through the axle and the wheel is drilled. The structure is complex, Manufacturing precision is high. The diameter of the inclined hole is φ16mm, the depth of the hole is 190mm, and the position is φ0.05mm. It is a multi-level, high-diameter dynamic environment, and the function of the machine tool itself cannot meet the technical requirements. This requires ...
