Driving device suitable for rail train wheel set measuring machine and control method thereof

Abstract

The invention discloses a driving device suitable for a rail train wheel set measuring machine and a control method thereof. The driving device comprises a chuck, a laser ranging sensor, a rotating motor and a stepping mechanism; the chuck comprises a chuck at the head end and a connecting shaft at the tail end, and the connecting shaft is connected with a power output shaft of the rotating motor;the rotating motor drives the connecting shaft to rotate, a feeding mechanism is arranged at the bottom of the connecting shaft and the bottom of the rotating motor, and the chuck is driven by the feeding mechanism to complete feeding and retreating actions; and the chuck is driven by a ball screw to clamp an axle, so that the device has the advantages of high positioning precision, high controlprecision, convenience in adjustment and the like. According to the driving device suitable for the rail train wheel set measuring machine and the control method thereof, the rubber head chuck, a heavy-load sliding rail, a spring clamping jaw, the laser ranging sensor and other devices are combined, the controllability, accuracy and automation degree of the wheel set measuring machine are enhanced, adjustment is easier, meanwhile, the axle is protected, the measuring process is more efficient, and geometric parameters of a measured wheel set are more accurate.

Description

technical field [0001] The invention relates to the technical field of rail train wheel set measurement, in particular to a driving device suitable for a rail train wheel set measuring machine and a control method thereof. Background technique [0002] As the load-bearing and moving parts of the train, the rail train wheel set bears a large load and impact. For the train that needs to run at high speed, the geometric parameters of the wheel set are particularly important. With the mechanized production process, manual measurement can no longer meet the current production needs. The development and improvement of wheel set measuring machines have made the measurement of wheel set geometric parameters more efficient and accurate. 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 ...
