Processing measurement tool of ring slot

Abstract

The invention relates to the field of measurement tool technologies, in particular to a processing measurement tool of a ring slot. Through the tool, the defect that manpower and man-hours are wastedin the prior art is overcome. The tool comprises a base and a flange, wherein a support is fixed to the top of the base through bolts, a rotating rod is rotationally installed in the support, the twoends of the rotating rod are connected with a handle and a measurement body through screws respectively, a sliding block is arranged at the outer side of the rotating rod in a sliding mode, the two ends of the measurement body are provided with telescopic slots respectively, and a telescopic plate is connected into the telescopic slots in a sliding mode. Through the arrangement of a measurement mechanism, the telescopic plate, the rotating rod, the sliding block, a first connecting rod, a second connecting rod, the handle and other structures, during processing of the ring slot of a fan shell,the forming width of the ring slot can be determined through a measuring probe, and then the tool is placed in the fan shell to mark out a processing location of the ring slot. Therefore, precision is high, processing measurement of the ring slot can be completed at a time, and manpower and man-hours are saved.

Description

technical field [0001] The invention relates to the technical field of measuring tools, in particular to a measuring tool for machining ring grooves. Background technique [0002] The existing machining and measuring tool for the ring groove of the fan casing is a vernier caliper, but due to its structural limitation, if the size of the caliper head is larger than the local space of the ring groove to be measured, it cannot measure the size of the ring groove in a full circle, so it is often necessary to turn the casing Disassemble the upper and lower bodies, and then use a caliper to measure the dimensions at both ends of the ring groove at the split surface of the casing. [0003] However, from rough machining to finishing machining of the casing ring groove, it is necessary to repeatedly disassemble the upper and lower casings for multiple measurements, which consumes a lot of manpower and working hours.
