Problems solved by technology

[0003] The measurement principle of the laser probe is usually the triangulation method, which requires the sensor to face the product. In the scanning of complex parts, such as blades and screws, the angle of incident light is often not good, and the angle of reflected light exceeds the receiving range. The current technology is only the rotation of the Z axis to compensate the incident angle of the laser, but the incident angle caused by the tilt of the product is out of range. This technology cannot compensate. It needs a space steering gyroscope structure to solve it, which is very troublesome.

Abstract

The invention discloses a control device for automatically adjusting a laser incident angle and a using method thereof. The device comprises a working box, a clamping mechanism is arranged at one end of the top of the working box, a Y-axis moving mechanism is arranged at the top of the end, close to the clamping mechanism, of the working box, a Z-axis moving mechanism is arranged at the top of the Y-axis moving mechanism, and an X-axis moving mechanism is arranged at one end of the outer wall of the Z-axis moving mechanism. Damping mechanisms are arranged at the dead corners of the bottom of the working box. The Y-axis moving mechanism comprises a moving block. The Z-axis moving mechanism comprises a movable block. The beneficial effects of the control device are that a product is actively adjusted to face a laser head through rotation of a rotary table according to the shape change of the product, and self-adaptive measurement of the laser incident angle can be realized; a linear motor drives the moving block to move, a second stepping motor drives the movable block to move, and a second electric push rod drives an extension rod to move, so that the position of a laser distance measuring sensor is conveniently adjusted; and a hydraulic cylinder drives a hydraulic rod to move to facilitate damping of the device, meanwhile, the overall length can be changed, and the device can be kept horizontal.

Description

technical field [0001] The invention relates to the technical field of laser measurement, in particular to a control device for automatically adjusting a laser incident angle and a method for using the same. Background technique [0002] Laser measurement technology has been commercialized, samples have been made, a lot of experience has been accumulated, and many practical problems have been solved. It has a good market prospect. This technology has universal adaptability, especially for products with large curvature changes.
