Anti-collision method of laser cladding head

Abstract

The invention discloses an anti-collision method of a laser cladding head, and the method is characterized in that the method comprises the following steps: 1) installing an ultrasonic ranging sensorwith temperature compensation on the laser cladding head, installing the sensor at a proper position, and measuring the distance between the laser cladding head and a workpiece by the sensor; 2) starting the sensor, and setting a safe distance between the laser cladding head and the workpiece on a control system interface, wherein the sensor is used for monitoring the distance between the laser cladding head and the workpiece in real time; 3) enabling the sensor to process the real-time monitored distance and temperature information and feed back the processed information to the control system, enabling the control system to output a driving instruction for the Z axis of the laser cladding head according to the received signal, instructing the servo to operate according to a preset programwhen the control system receives a safety signal, instructing the motor to stop when the control system receives a danger signal, and prompting danger alarm information on the display screen. Due tothe fact that the sensor is arranged on the laser cladding head, the laser cladding head can be effectively prevented from colliding with a workpiece, and the laser cladding head is protected againstdamage.

Description

technical field [0001] The invention relates to the field of laser cladding, in particular to an anti-collision method for a laser cladding head. Background technique [0002] As an effective means of material surface modification technology, laser cladding technology can significantly improve the strength, hardness, wear resistance, high temperature oxidation resistance, corrosion resistance and other properties of the surface of metal materials. Most of the existing laser cladding equipment does not have the anti-collision function of the laser cladding head. In the actual operation process, due to the unreasonable movement path of the preset laser cladding head or human error, etc., it is easy to cause the laser cladding head to collide with the workpiece. Collision will affect the accuracy of the laser cladding head at least, and damage the laser cladding head at worst, which will bring unnecessary economic losses to the enterprise.
