Description

Technical Field

[0001] This utility model relates to the field of laser technology, and in particular to an ellipsoidal mirror assembly. Background Technology

[0002] Ellipsoidal mirrors are used in laser processing equipment to focus or reflect laser beams. Any minute deformation of the mirror surface can lead to a decrease in beam quality and affect processing accuracy. During laser processing, the equipment temperature may change, and the mirror surface stress caused by temperature changes can lead to deformation of the ellipsoidal mirror.

[0003] Therefore, ellipsoidal mirrors require flexible fixing primarily to prevent mirror deformation, reduce vibration effects, adapt to temperature changes, protect the mirror surface, improve adjustment accuracy, extend service life, and adapt to complex working conditions. Flexible fixing ensures the stability and reliability of the ellipsoidal mirror in high-precision optical systems, thereby improving the quality and efficiency of laser processing.

The ellipsoidal mirror is mounted in the positioning hole of the large-end positioning plate. The small-end mounting component fixes the small end of the ellipsoidal mirror. The flexible pre-tightening component connects to the small-end mounting component and is located on the support plate.

[0006] Furthermore, several positioning springs are provided on the large end positioning plate at the edge of the corresponding positioning hole.

[0007] Furthermore, the positioning springs are evenly distributed along the edge of the positioning holes.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.

[0021] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.

[0022] Please refer to Figures 1-5The ellipsoidal mirror assembly of this utility model includes an ellipsoidal mirror, a small-end mounting component, a flexible pre-tightening component, a large-end positioning plate, and a support plate.

[0023] The large-end positioning plate has positioning holes that match the large end of the ellipsoidal mirror. The ellipsoidal mirror is installed in the positioning holes of the large-end positioning plate, and the small-end mounting piece fixes the small end of the ellipsoidal mirror. A flexible pre-tightening component connects to the small-end mounting piece and is located on the support plate. The ellipsoidal mirror is clamped using a large-end centering and small-end pre-tightening method; that is, the large-end positioning plate is used for axial positioning of the ellipsoidal mirror, and the small-end mounting piece pre-tightens the small end of the ellipsoidal mirror. The flexible pre-tightening component is a flexible pre-tightening flange. The flexible pre-tightening flange provides axial pre-tightening force to the ellipsoidal mirror while releasing the translational freedom of the ellipsoidal mirror in the horizontal plane, reducing the risk of high-temperature breakage of the ellipsoidal mirror.

[0024] In one implementation, a plurality of positioning springs are provided on the large-end positioning plate at the edge of the positioning hole. The positioning springs are evenly distributed along the edge of the positioning hole. Preferably, four positioning springs are used, with a 90° interval between them. This invention uses positioning springs for positioning and provides radial flexibility.

[0025] In one embodiment, the positioning spring consists of a mounting part, an elastic part, and an action part. The mounting part is connected to the large-end positioning plate, the elastic part connects the mounting part and the action part, and the action part contacts the ellipsoidal mirror. The elastic part applies pressure to the action part, causing the action part to apply pre-pressure to the ellipsoidal mirror, thereby reducing the impact of vibration.

[0026] In one implementation, the small-end mounting component uses a ceramic ring. The ceramic ring is fitted around the outer periphery of the small end of the ellipsoidal mirror.

[0027] In practical implementation, screw holes are provided on the support plate and the large end positioning plate to facilitate the installation of the ellipsoidal mirror assembly of this utility model into the laser by bolts.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
