Description

Technical Field

[0001] This utility model belongs to the field of internal engraving fixture technology, specifically relating to a general laser internal engraving machine for engraving spherical and irregularly shaped surfaces. Background Technology

[0002] Ordinary 355 and 532 model laser engraving machines can only engrave three-dimensional cubes internally, and cannot directly engrave spheres or irregular shapes. Therefore, spherical or irregular shaped internal engraving parts generally require specialized internal engraving machines. To address this, we propose a universal laser internal engraving machine fixture for engraving spherical and irregular surfaces.

[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0004] The purpose of this invention is to provide a universal laser engraving machine for engraving spherical and irregularly shaped surfaces.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A general-purpose laser engraving machine uses a spherical and irregularly shaped surface engraving fixture. The fixture includes a bottom mounting base for the engraving machine, an engraving object bracket, an engraved object, an upper fixing frame, an optical module, and a top cover. The engraved object bracket is fixed to the bottom mounting base via a bracket mounting groove. The engraved object is positioned between the engraved object bracket and the upper fixing frame. The optical module is connected to the upper fixing frame via an optical module mounting groove. A top cover is provided above the optical module. The upper fixing frame is connected to the bottom mounting base for the engraving machine via an upper fixing frame positioning groove and a mounting base positioning groove.

[0006] Preferably, the inner carving is spherical or irregular in shape.

[0007] Preferably, a highly transparent oil is injected between the optical module and the inner carving.

[0008] Preferably, the lower surface of the optical module is provided with a groove.

[0009] Preferably, the groove is a spherical groove or an irregularly shaped groove.

[0010] Preferably, the top cover plate has a light-transmitting groove in the middle.

[0011] Preferably, the top cover plate has two sides on its upper surface.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention can achieve internal engraving on spherical or irregularly shaped objects using ordinary 355 and 532 laser engraving machines, eliminating the need for a dedicated internal engraving machine. It ensures that the spherical or irregularly shaped object does not rotate while allowing the laser to enter the designated position without loss. This invention features a compact design, convenient operation, strong versatility, and is suitable for industrial production. Attached Figure Description

[0014] The technical solution of this utility model patent will be clearly and completely described below. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0015] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to a connection within two components.

[0017] See attached document Figure 1A general-purpose laser engraving machine uses a spherical and irregularly shaped surface engraving fixture. The engraving fixture includes a bottom mounting base 1 for the engraving machine, an engraving object bracket 2, an engraved object 3, an upper fixing frame 4, an optical module 5, and a top cover plate 6. The engraved object bracket 2 is fixed to the bottom mounting base 1 for the engraving machine through a bracket mounting groove 1-1. The engraved object 3 is disposed between the engraved object bracket 2 and the upper fixing frame 4. The optical module 5 is connected to the upper fixing frame 4 through an optical module mounting groove 4-1. A top cover plate 6 is disposed above the optical module 5. The upper fixing frame 4 is connected to the bottom mounting base 1 for the engraving machine through an upper fixing frame positioning groove 4-2 and a mounting base positioning groove 1-2.

[0018] The inner carving 3 can be spherical or irregular in shape.

[0019] The lower surface of the optical module 5 is provided with a groove, which can be spherical or irregularly shaped. The groove allows the printed inner carving 3 (e.g., a spherical crystal) to adhere to the module. High-transparency oil is injected between the optical module 5 and the inner carving 3 to ensure complete adhesion. This prevents the inner carving 3 from rotating and allows the laser to enter the designated position on the inner carving 3 without loss. This method can be used for other non-planar inner carvings 3, as long as their surfaces can be polished and have a regular shape.

[0020] The top cover plate 6 has a light-transmitting groove 6-1 in the middle, which allows the laser to enter the inner carving object 3 through the optical module 5 to realize the inner carving tooling.

[0021] The top cover plate 6 has 6-2 on both sides of its upper surface to facilitate replacement of the top cover plate 6.

[0022] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings. The exemplary embodiments were chosen and described in order to explain the specific principles of the present invention and its practical application, thereby enabling those skilled in the art to implement and utilize various different exemplary embodiments of the present invention, as well as various different choices and variations. The scope of the present invention is intended to be defined by the claims and their equivalents.
