[0002] Laser scanning technology, with its unique advantages such as high precision, high efficiency, and non-contact measurement, is profoundly changing the technological landscape of many industries. In industrial manufacturing, it has enabled a leap from traditional manual inspection to intelligent quality control; in the autonomous driving industry, it has become a core sensor for environmental perception systems; in healthcare, it provides new technological means for precision medicine; and in national defense and security, it has significantly improved the combat effectiveness of military reconnaissance and guided weapons. These wide-ranging and in-depth applications have not only promoted the upgrading and transformation of related industries but also had a profound impact on the enhancement of national scientific and technological innovation capabilities and economic and social development.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 4 This utility model provides a technical solution:

[0025] A laser pitch and yaw scanning platform includes: a first motor bracket 1 and a second motor bracket 2; a first stepper motor 3, fixed to the upper end of the second motor bracket 2 and connected by four first screws; a second stepper motor 4, fixed to one side of the first motor bracket 1 and connected by four first screws, the output shaft of which passes through the first motor bracket 1 and is connected to the second motor bracket 2 by second screws. When the second motor bracket 2 rotates back and forth, it can drive the first stepper motor 3 to rotate back and forth as a whole. Both the first stepper motor 3 and the second stepper motor 4 are 28 stepper motors.

[0026] In this embodiment, the output shaft of the first input motor 3 is connected to a flange bracket 5, which is fixed by two second screws. A bearing seat 6 is provided inside the flange bracket 5 and is fixed by four third screws. When the second motor bracket 2 rotates, driving the first input motor 3 to rotate back and forth, it can drive the flange bracket 5 and the internal bearing seat 6 to rotate back and forth. When the output shaft of the first input motor 3 rotates, it can drive the flange bracket 5 and the internal bearing seat 6 to rotate left and right.

[0027] In this embodiment, the laser pitch and yaw scanning platform also includes a rotating shaft 8, wherein the rotating shaft 8 passes through the first motor bracket 1 and the second motor bracket 2, and the rotating shaft 8 is rigidly connected coaxially with the output shaft of the second input motor 4 and the second motor bracket 2. When the output shaft of the second input motor 4 rotates, it can drive the second motor bracket 2 and the rotating shaft 8 to rotate.

[0028] In this embodiment, an elastic washer 9, a bearing 10, and a flat washer 11 are sequentially fitted onto the rotating shaft 8, and it is connected to the second motor bracket 2 by a second screw; the same elastic washer 9, bearing 10, and flat washer 11 are coaxially fitted onto the output shaft of the second motor 4. Among them, the elastic washer 9 provides axial preload, the bearing 10 bears radial or axial load, and the flat washer 11 disperses stress and protects the bearing end face.

A threaded pin 12 is provided on the second motor bracket 2 to avoid the problem of excessive angle when the second motor bracket 2 rotates back and forth.

[0030] The implementation method of this utility model is as follows: A laser beam is emitted from one side of the bearing seat 6 and transmitted through the central circular hole of the bearing seat 6 to the other side. By controlling the output shaft of the first input motor 3 to rotate, the bearing seat 6 fixed on the flange bracket 5 is driven to rotate, thereby realizing the left and right movement of the beam. By controlling the output shaft of the second input motor 4 to rotate, the rotating shaft 8 and the second motor bracket 2 are driven to rotate back and forth, thereby driving the first input motor 3 to rotate, and then driving the bearing seat 6 on the flange bracket 5 to rotate back and forth, thereby realizing the up and down movement of the beam.
