Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, and in particular to a weight-reducing laser connector. Background Technology

[0002] As a core energy transmission component of metal 3D printing equipment, the laser connector is responsible for the precise transmission and focusing of the laser beam and its stable connection to the main body of the equipment. Current laser connector technologies still have the following technical problems that need to be addressed: 1. Traditional connectors are mostly assembled after machining. For example, the easy-to-operate laser welding head mentioned in CN202420605226.3 requires splicing of multiple parts, which is prone to stress concentration and assembly errors, affecting the laser transmission accuracy. 2. Some lightweight solutions, such as CN202420822533.7, reduce weight by simplifying the optical path, but do not design the core support structure of the connector, resulting in insufficient rigidity after lightweighting, which cannot adapt to the high-frequency dynamic operation of 3D printing equipment. 3. Existing heat dissipation solutions, such as CN202323258433.0 which uses external water cooling and CN202411579617.3 which uses meshing transmission cooling components, generally suffer from bulky structures or complex transmissions, making them difficult to be compatible with lightweight requirements. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model provides a technical solution that can solve the above problems.

[0004] The weight-reducing laser connector includes a positioning flange, a gradient support, and a laser transmission part, all integrally formed using metal 3D printing technology. The bottom side of the positioning flange is formed with a laser mounting cylinder and an outer protective cylinder. The outer protective cylinder is located outside the laser mounting cylinder, and a heat dissipation gap is left between the laser mounting cylinder and the outer protective cylinder. Multiple first heat dissipation holes are arranged in a circular array on the outer periphery of the upper end of the outer protective cylinder, and the heat dissipation gap and the first heat dissipation holes are interconnected. The gradient support is integrally formed and disposed at the lower end of the outer protective cylinder, and the laser conduction part is integrally formed and disposed at the lower end of the gradient support. The outer circumference of the laser transmission part is integrally formed with a widened cylinder, and a weight-reducing cavity is formed between the widened cylinder and the laser transmission part. An air inlet is formed on the outer side of the bottom end of the widened cylinder, and a second heat dissipation hole is formed on the upper end of the laser transmission part. The second heat dissipation hole is conducted to the heat dissipation gap through the gradient support part.

[0005] Furthermore: multiple reinforcing edges are formed between the bottom end of the laser mounting cylinder and the outer protective cylinder. The multiple reinforcing edges are arranged in a circular array between the laser mounting cylinder and the outer protective cylinder. The upper end of the reinforcing edge and the positioning flange are separated from each other to form a heat dissipation conduction part. The inner end of the first heat dissipation hole is connected to the heat dissipation conduction part.

[0006] Furthermore, the bottom side of the reinforcing edge is integrally formed with a weight-reducing groove, and the weight-reducing groove and the heat dissipation gap are separated by the reinforcing edge.

[0007] Furthermore: the positioning flange adopts a square plate structure, and countersunk mounting holes are integrally formed at all four ends of the positioning flange.

[0008] Furthermore, the widened cylinder and the laser transmission part are integrally formed with two or more radially penetrating lightweight holes.

[0009] Furthermore: a first chamfer is integrally formed between the positioning flange and the gradient support, and a second chamfer is integrally formed between the gradient support and the laser transmission part.

[0010] Furthermore, the heat dissipation gap is designed to be narrower at the top and wider at the bottom.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. The positioning flange, gradient support, and laser transmission parts are integrally formed using metal 3D printing technology, which avoids the stress concentration problem caused by splicing and assembly after traditional machining, greatly reduces assembly errors, and ensures the accuracy of the laser beam transmission path. At the same time, the integrated structure enhances the overall rigidity of the connector, which can adapt to the high-frequency dynamic operation requirements of 3D printing equipment and solves the defect of insufficient rigidity caused by neglecting the core support structure in existing lightweight solutions.

[0012] 2. Achieving compatibility between lightweight design and efficient heat dissipation through multiple structural designs: On the one hand, utilizing the heat dissipation gap between the laser mounting cylinder and the outer protective cylinder, and the weight-reducing cavity between the widened cylinder and the laser transmission part, the overall weight of the connector is significantly reduced without affecting the structural strength; on the other hand, a closed-loop active heat dissipation channel is constructed. After high-pressure gas enters from the air inlet, it passes through the weight-reducing cavity, the second heat dissipation hole, the heat dissipation gap, and the heat dissipation conduction part before being discharged from the first heat dissipation hole. The airflow fully flows through the core heat-generating area, quickly removing heat and preventing overheating of the laser component during operation. This solves the problems of bulky structure, complex transmission, and conflict with lightweight requirements of existing external water cooling and complex transmission cooling components.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] like Figure 1-3 As shown, the weight-reducing laser connector of this utility model includes a positioning flange 1, a gradient support 2, and a laser transmission part 3, which are integrally formed by metal 3D printing technology. The bottom side of the positioning flange 1 is formed with a laser mounting cylinder 4 and an outer protective cylinder 5. The outer protective cylinder 5 is located outside the laser mounting cylinder 4, and a heat dissipation gap 6 is left between the laser mounting cylinder 4 and the outer protective cylinder 5. Multiple first heat dissipation holes 7 are arranged in a circular array on the outer periphery of the upper end of the outer protective cylinder 5. The heat dissipation gap 6 and the first heat dissipation holes 7 are interconnected. The gradient support part 2 is integrally formed and disposed at the lower end of the outer protective cylinder 5, and the laser conduction part 3 is integrally formed and disposed at the lower end of the gradient support part 2. The outer circumference of the laser transmission part 3 is integrally formed with a widened cylinder 8, and a weight reduction cavity 9 is formed between the widened cylinder 8 and the laser transmission part 3. An air inlet 10 is formed on the outer side of the bottom end of the widened cylinder 8, and a second heat dissipation hole 11 is formed on the upper end of the laser transmission part 3. The second heat dissipation hole 11 is conducted to the heat dissipation gap 6 through the gradient support part 2. The principle is as follows: When in use, the laser component is installed into the laser mounting cylinder 4, the gradient support part 2, and the laser conduction part 3. First, high-pressure gas is introduced into the air inlet 10 at the bottom of the widened cylinder 8. The airflow will quickly pass through the weight-reducing cavity 9 formed by the widened cylinder 8 and the laser conduction part 3 to achieve the effect of actively removing heat. It is then transported from the second heat dissipation hole 11 to the gradient support part 2, and then from the heat dissipation gap 6 to the first heat dissipation hole 7 to dissipate heat and prevent the laser component from overheating during operation. In addition to the heat dissipation effect, the heat dissipation gap 6 and the weight-reducing cavity 9 also reduce the overall weight of the laser connector, achieving a lightweight design.

[0023] Furthermore, multiple reinforcing edges 12 are formed between the bottom end of the laser mounting cylinder 4 and the outer protective cylinder 5. The multiple reinforcing edges 12 are arranged in a circular array between the laser mounting cylinder 4 and the outer protective cylinder 5. The upper end of the reinforcing edge 12 and the positioning flange part 1 are separated from each other to form a heat dissipation conduction part 13. The inner end of the first heat dissipation hole 7 is connected to the heat dissipation conduction part 13. The reinforcing edges 12 can strengthen the connection strength between the laser mounting cylinder 4 and the outer protective cylinder 5, and ensure the overall life of the laser connector. In addition, the multiple reinforcing edges 12 can also be used as heat dissipation fins, which can effectively increase the contact area between the laser mounting cylinder 4 and the flowing high-pressure gas, realize the rapid removal of heat, and further ensure the heat dissipation effect.

[0024] Furthermore, the bottom side of the reinforcing edge 12 is integrally formed with a weight-reducing groove 14, which is separated from the heat dissipation gap 6 by the reinforcing edge 12; this can better reduce weight while ensuring overall strength.

[0025] Furthermore: the positioning flange 1 adopts a square plate structure, and countersunk mounting holes 15 are integrally formed at all four ends of the positioning flange 1; the positioning flange 1 can be assembled by passing screws through the countersunk mounting holes 15, which facilitates the installation and use of the entire laser connector.

[0026] Furthermore, the widened cylinder 8 and the laser transmission part 3 are integrally formed with two or more radially penetrating lightweight holes 16, which facilitates the installation and use of the laser assembly.

[0027] Furthermore: a first chamfer 17 is integrally formed between the positioning flange 1 and the gradient support 2, and a second chamfer 18 is integrally formed between the gradient support 2 and the laser transmission part 3; the chamfers can be used to achieve a transition, effectively avoid stress concentration, and prevent deformation when dropped, thus ensuring the service life of the overall laser connector.

[0028] Furthermore, the heat dissipation gap 6 is narrower at the top and wider at the bottom, which can achieve the effect of airflow guidance and ensure the effectiveness of heat dissipation.

[0029] Furthermore, the weight-reducing laser connector is integrally formed using titanium alloy, aluminum alloy, or high-strength stainless steel through selective laser melting (SLM) or electron beam melting (EBM) metal 3D printing technology; it can achieve an integral molding design, ensuring the strength and service life of the overall laser connector, and avoiding a series of defects caused by splicing and assembly in the existing technology.

[0030] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
