A driving device and control method for wheelset measuring machine of rail train

Abstract

The invention discloses a driving device suitable for a rail train wheelset measuring machine and a control method thereof, comprising a chuck, a laser ranging sensor, a rotating motor and a stepping mechanism, wherein the chuck comprises a chuck at the head end and a chuck at the tail end. a connecting shaft, the connecting shaft is connected with the power output shaft of the rotating electrical machine, and is driven to rotate by the rotating electrical machine; the connecting shaft and the bottom of the rotating electrical machine are provided with the feeding mechanism, and the feeding mechanism is The mechanism drives the chuck to complete the feeding and retracting actions; the ball screw is used to drive the chuck to clamp the axle, which has the advantages of high positioning accuracy, high control precision, convenient adjustment, etc. The combination of rails, spring jaws and laser ranging sensors enhances the controllability, accuracy and automation of the wheelset measuring machine, and makes it easier to adjust, while protecting the axle, making the measurement process more efficient, measuring wheelset The geometric parameters are more precise.

Description

technical field [0001] The invention relates to the technical field of rail train wheelset measurement, in particular to a drive device and a control method thereof suitable for a railroad train wheelset measurement machine. Background technique [0002] As the load-bearing and moving parts of the train, the wheelset of the rail train bears a large load and impact force. For the train that needs to run at high speed, the geometric parameters of the wheelset are particularly important. With the process of mechanized production, manual manual measurement can no longer meet the current production needs. The development and improvement of wheelset measuring machines have made the measurement of wheelset geometric parameters more efficient and accurate. When the wheelset measuring machine is clamped and the axle is rotated, it is easy to cause inaccurate positioning, scratches to the axle, and loss of rotation when rotating the axle, which will cause large errors in the measureme...

AI Technical Summary

Problems solved by technology

When the wheel set measuring machine clamps and rotates the axle, it is easy to cause inaccurate positioning, scratches on the axle, and loss of rotation when rotating the axle, which will cause large errors in the measurement results. How to improve the existing wheel For the measuring machine, it is an important direction for the development of the wheel set measuring machine to make the wheel set measuring machine suitable for different axles and reduce the error when the wheel set is clamped and rotated.
