Measuring device and method for rapidly measuring rotor shaft sleeve

Abstract

The invention relates to a measuring device and method for rapidly measuring a rotor shaft sleeve. The method comprises the steps of 1 preparing: 1.1, placing a measuring flat plate on a working platform of a three-coordinate measuring machine, enabling the measuring flat plate to be tightly attached to the working platform, enabling the X-axis direction and the Y-axis direction of the measuring flat plate to be consistent with the X-axis direction and the Y-axis direction of the working platform, and fixing the measuring flat plate on the working platform by a fastening screw; 1.2 fixing a plurality of groups of fixing seats on the measuring flat plate in parallel at equal intervals, and enabling the center connecting line of the two counterbores in the fixing seats to keep consistent with the X-axis direction or the Y-axis direction of the measuring flat plate; 1.3installing a plurality of workpieces in horizontal installation holes in the fixing seats one by one, ensuring that the positioning datum plane of the fixing seats makes full contact with the positioning datum plane of the rotor shaft sleeve, and then tightening fixing screws to fix workpieces; and 2 adopting a high-precision three-coordinate measuring machine with a star-shaped measuring head, and achieving rapid batch measurement of the workpieces by establishing a workpiece coordinate system and editing a cyclic measurement program. According to the invention, the measurement precision and the measurement efficiency of the workpieces are improved.

Description

technical field [0001] The invention belongs to the field of torque motor production and manufacturing, and relates to a measurement technology of a rotor shaft sleeve, in particular to a measuring device and a measurement method for rapidly measuring a rotor shaft sleeve. Background technique [0002] The torque motor has low manufacturing cost and reliable performance. It can provide stable torque to the load when the motor is running at a low speed. It is widely used in machinery manufacturing, aviation, navigation, weaponry and other fields. Torque motors are in great demand in scientific research and production, and the rotor bushing is an important part of the torque motor, and the efficient and accurate measurement of its various shapes and sizes is particularly important. [0003] Due to the structural characteristics of the rotor bushing 100, there is an annular beam 102 between the two precision bearing holes 101, which causes the existing precision measurement tec...

Problems solved by technology

[0003] Due to the structural characteristics of the rotor bushing 100, there is an annular beam 102 between the two precision bearing holes 101, which causes the existing precision measurement technology to be unable to simultaneously measure the size of the two precision bearing holes and the shape and position tolerances between the key elements , and the coaxiality between two precision bearing holes can only be measured manually
