Abstract

The invention provides a device and a method for measuring the symmetry of a rudder shaft slot of a rudder shaft part. A gauge block I, a gauge block II and a gauge block III are connected side by side above a base through connecting screws. A dial gauge is adsorbed to the base by magnetic force, and is arranged near the gauge block I, the gauge block II or the gauge block III as needed during measurement. The gauge block I, the gauge block II and the gauge block III are set to adapt to rubber shafts with different slot width, and can be disassembled. During measurement, one side in a rudder shaft slot of a rudder shaft part is put close to one gauge block; the contact of the dial gauge contacts the conical surface of the rubber shaft, the rubber shaft is moved along the surface of the gauge block, and the maximum reading of the dial gauge is recorded; the rubber shaft is turned so the other side in the rubber shaft slot is put close to the gauge block; the contact of the dial gauge contacts the conical surface of the rubber shaft, the rubber shaft is moved along the surface of the gauge block, and the maximum reading of the dial gauge is recorded again; and the absolute value of the difference between the two readings of the dial gauge is the symmetry. The device of the invention has a simple structure and a good application effect. The method of the invention is easy to operate, and costs low.

Description

technical field [0001] The invention belongs to a device for detecting symmetry of groove parts, in particular to a device and method for detecting symmetry of rudder shaft grooves of rudder shaft parts. Background technique [0002] The rudder shaft part is a key part in the transmission assembly of the missile weapon, and its machining accuracy is directly related to the flight control accuracy of the missile weapon. Therefore, there are very strict requirements on the accuracy of shape, position and size, which is mainly reflected in the requirements on the symmetry of the rudder shaft groove. Such as figure 1 shown. [0003] The machining process of the rudder shaft groove needs to go through multiple processes such as wire-cut roughing, wire-cut finishing, rough milling, and fine milling. In order to control the machining accuracy and calculate the machining allowance accurately, it is necessary to measure the symmetry of the rudder shaft groove after each process is...
