A kind of fast measuring device and measuring method of deflection of long part

Abstract

The invention discloses a fast measuring device and a measuring method for the deflection of a large part. The measuring device includes a frame, and three ball screw modules are arranged on the same line along the same line, and a servo motor is arranged at one end of the ball screw module. A sliding table is fixedly installed on the mounting plate above the ball screw module, an L-shaped mounting plate is arranged on the sliding table, and a laser displacement sensor is installed on the upper end of the L-shaped mounting plate; the L-shaped mounting plates on both sides are respectively set oppositely There is a through-beam laser sensor; a controller is arranged on the frame, and the controller is electrically connected with the laser displacement sensor, the servo motor, and the through-beam laser sensor; the measurement method includes placing the measuring device under the workpiece to be measured, and using The rack is parallel to the workpiece to be measured. The invention can solve the problem of lack of accurate measurement of the deflection of long parts in the prior art, and has high detection precision, strong adjustability and fast detection speed.

Description

technical field

[0001] The invention relates to the technical field of rail vehicles, in particular to a fast measuring device and a measuring method for the deflection of a long component. Background technique

[0002] Deflection refers to the linear displacement of the axis of the rod line in the direction perpendicular to the axis when the force is applied or the temperature is not uniform. In parts, such as EMUs or subway car body sites, the measurement of deflection is particularly important.

[0003] The measurement methods at the present stage are relatively simple, which will cause deviations in the installation of the measurement device when measuring large parts, and cannot effectively control the exact position of each measurement point. At the same time, the data obtained by some traditional measurement methods The accuracy is not high, and the measurement error is large; at the same time, using other direct deflection measurement methods, whether it is laying o...
