Description

Technical Field

[0001] This application relates to the field of laser technology, and in particular to clamping and positioning structures and laser heads. Background Technology

[0002] In laser processing systems, optical components such as collimating lenses, focusing lenses, and protective lenses each play a crucial role. They work together to ensure that the laser beam can efficiently and accurately complete material processing tasks.

[0003] To ensure these optical components can operate stably under extreme conditions, they need to be securely fixed. Taking a focusing lens as an example, if the locking force of the focusing lens is not firm, it may cause the position of the focusing lens to shift, which in turn will cause changes in the focal length, directly affecting the energy density distribution on the workpiece, thereby affecting the processing quality and efficiency.

[0004] In related technologies, fixtures used to fix optical components suffer from unreliable fixing issues. Utility Model Content

[0005] Based on this, to address the problem of unreliable fixing in fixtures used to fix optical components, a clamping and positioning structure and a laser head are provided.

[0006] A clamping and positioning structure, the clamping and positioning structure comprising:

[0007] The first mounting base has a first connecting hole and a first locking hole;

[0008] The second mounting base has a second connecting hole;

[0009] A connector, one end of which is connected to the first connecting hole and the other end of which is connected to the second connecting hole; the connector is configured with a locking part;

[0010] A locking member, which passes through the first locking hole and is connected to the locking part;

[0011] The axial direction of the first connecting hole is set at an angle to the axial direction of the first locking hole.

[0012] In one embodiment, at least a portion of the locking member is in surface contact with the locking portion.

[0013] In one embodiment, the locking member has a first mating slope at one end facing the locking portion; the locking portion has a second mating slope for abutting against the first mating slope.

[0014] In one embodiment, the second mating inclined surface comprises two surfaces, which are arranged along the axial direction of the connector and whose extending directions intersect.

[0015] In one embodiment, the connector is provided with an operating part for connecting an installation tool.

[0016] In one embodiment, the operating part includes an operating hole;

[0017] And / or, the operating part includes an operating plane.

[0018] In one embodiment, one of the first mounting base and the second mounting base is connected to a positioning detection element for detecting the other.

[0019] In one embodiment, one of the first mounting base and the second mounting base is provided with a positioning part, and the other is provided with a positioning hole for cooperating with the positioning part.

[0020] In one embodiment, the positioning hole is configured as a through hole; the positioning part is configured as a stepped shaft that engages with the through hole.

[0021] A laser head includes an optical element and a clamping and positioning structure as described above; the optical element is connected between a first mounting base and a second mounting base.

[0022] The aforementioned clamping and positioning structure and laser head include a first mounting base, a second mounting base, a connector, and a locking member. The first locking hole and the first connecting hole of the first mounting base are axially angled, meaning the connector and the locking member intersect. This allows the connector and the locking member to provide constraint forces in multiple directions. Compared to existing screw connections, this effectively improves the connection between the first and second mounting bases, better resists vibration, and reduces the risk of relative movement or rotation between the first and second mounting bases. This enhances the locking effect of components such as optical elements connected between the first and second mounting bases, ensuring the laser beam can efficiently and accurately complete material processing tasks, thereby guaranteeing processing quality.

[0034] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0035] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application 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, and therefore should not be construed as a limitation of this application.

[0036] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0037] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; 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; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0039] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0040] See Figures 1 to 3As shown, an embodiment of this application provides a clamping and positioning structure including a first mounting base 100, a second mounting base 200, a connector 300, and a locking member 400; the first mounting base 100 is configured with a first connecting hole 110 and a first locking hole 120; the second mounting base 200 is configured with a second connecting hole 210; one end of the connector 300 is connected to the first connecting hole 110, and the other end of the connector 300 is connected to the second connecting hole 210, for example, in the attached... Figure 3 In the view shown, the upper end of the connector 300 is connected to the second mounting base 200 through the second connecting hole 210, and the lower end of the connector 300 is connected to the first mounting base 100 through the first connecting hole 110. The connector 300 is configured with a locking part 310. The locking member 400 passes through the first locking hole 120 and is connected to the locking part 310. The axial direction of the first connecting hole 110 is angled to the axial direction of the first locking hole 120. It can be understood that the first mounting base 100 and the second mounting base 200 are arranged along the axial direction of the first connecting hole 110. In the embodiment shown in the figure, the axial direction of the first connecting hole 110 is the vertical direction, that is, the up-down direction. The mounting device, such as an optical element, is connected between the first mounting base 100 and the second mounting base 200.

[0041] In actual assembly, the connector 300 can be first locked to the second mounting base 200, and then the connector 300 can be inserted into the first connecting hole 110 of the first mounting base 100; then the locking member 400 can be tightened so that the locking member 400 abuts against the connector 300. Since the first locking hole 120 and the first connecting hole 110 of the first mounting base 100 are angularly set, that is, the connector 300 and the locking member 400 intersect. In this way, the connector 300 and the locking member 400 can provide constraint forces in multiple directions. Compared with the existing screw connection method, it can effectively improve the connection effect between the first mounting base 100 and the second mounting base 200, better resist the influence of vibration, reduce the risk of relative movement or rotation between the first mounting base 100 and the second mounting base 200, thereby improving the locking effect of the assemblies such as optical elements connected between the first mounting base 100 and the second mounting base 200, ensuring that the laser beam can complete the material processing task efficiently and accurately, and thus ensuring the processing quality.

[0042] Understandably, there are multiple connectors 300 and locking components 400, and their numbers and positions correspond one-to-one. This increases the number of connection points between the first mounting base 100 and the second mounting base 200, thereby improving the connection effect between the first mounting base 100 and the second mounting base 200, and further ensuring the locking effect of the assembly connected between the first mounting base 100 and the second mounting base 200. For example... Figures 1 to 3As shown, in one embodiment, there are four connectors 300 and four locking members 400. In other embodiments, the number of connectors 300 and four locking members 400 may be two, three, or other numbers, and the specific number is not limited.

[0043] like Figures 3 to 5 As shown, in one embodiment, at least a portion of the locking member 400 is in surface contact with the locking portion 310. This increases the contact area between the locking member 400 and the connecting member 300. A larger contact area means higher friction, which provides a stronger locking force and ensures a more secure connection. Simultaneously, the increased contact area disperses the pressure applied to the contact surface, reducing localized stress concentration and lowering the risk of component fatigue or damage due to stress concentration. Furthermore, it reduces the risk of loosening of the first mounting base 100 and the second mounting base 200 due to vibration or other external forces, thereby ensuring the reliability of the locking mechanism.

[0044] like Figures 3 to 5 As shown, in one embodiment, the locking member 400 has a first mating inclined surface 410 at one end facing the locking portion 310; the locking portion 310 has a second mating inclined surface 311 for abutting against the first mating inclined surface 410. Through the interaction between the two mating inclined surfaces, an axial force is generated between the first mating inclined surface 410 and the second mating inclined surface 311 when the locking member 400 is tightened. This axial force presses the locking member 400 and the connecting member 300 together more tightly, increasing the strength and stability of the connection. Simultaneously, due to the presence of the first mating inclined surface 410 and the second mating inclined surface 311, even under vibration or other external forces, the two components are less likely to loosen due to continuous pressure, improving the reliability of the connection. Furthermore, the first mating inclined surface 410 and the second mating inclined surface 311 act as guides, making it easier to achieve precise alignment between the connecting member 300 and the locking member 400 during assembly, allowing operators to complete the assembly work more quickly.

[0045] like Figures 3 to 5As shown, in one embodiment, the second mating inclined surface 311 includes two surfaces, which are arranged along the axial direction of the connector 300 and intersect in their extending directions. For example, in the embodiment shown in the figure, the connector 300 is provided with two axially arranged conical surfaces, making the clamping part V-shaped. Thus, the two intersecting second mating inclined surfaces 311 can provide constraint forces in multiple directions, forming a self-locking mechanism. When subjected to external loads, the contact between the first mating inclined surface 410 and the second mating inclined surface 311 can automatically increase friction or generate reaction force to prevent loosening, thereby improving the connection effect of the first mounting base 100 and the second mounting base 200 and further improving the locking effect of the assembly. In other embodiments, the second mating inclined surface 311 can be provided only partially on the side of the connector 300, for example, the second mating inclined surface 311 is provided on the side of the connector 300 facing the locking member, and no second mating inclined surface is provided on the side away from the locking member.

[0046] like Figure 6 As shown, in other embodiments, the connector 300 may also be provided with only one second mating inclined surface 311, which can also improve the connection effect.

[0047] In some embodiments, the second mating slope may not be provided, the pressing part may be constructed as a threaded hole, the locking member is a fastening screw, the fastening screw passes through the locking hole and is threadedly connected to the threaded hole of the first connector to achieve locking.

[0048] like Figure 3 As shown, in some embodiments, the second connecting hole 210 can be a threaded hole, and the end of the connector 300 used to connect with the second connecting hole 210 is provided with an external thread. The connection between the connector 300 and the second mounting base 200 is achieved through the threaded engagement of the external thread and the threaded hole. In some embodiments, the connector 300 can be a connecting pin. The locking member 400 can be a fastening screw. In some embodiments, the head of the locking member 400 is provided with a rotating hole, such as an internal hexagon countersunk hole, to facilitate the insertion of an installation tool, such as a hexagonal wrench, to screw the locking member 400 into the locking hole and abut against the pressing part of the connector 300. In some embodiments, the first locking hole 120 is set in the form of a countersunk hole, so that the locking member 400 can be completely embedded in the countersunk hole, making the surface after installation smoother and flatter, without any protruding parts, and more aesthetically pleasing; it also provides a larger contact area and enhances the locking effect. At the same time, since the locking member 400 does not protrude from the surface of the first mounting base 100, the risk of accidentally scratching the operator is reduced.

[0049] like Figures 3 to 5As shown, in one embodiment, the connector 300 is provided with an operating part 320 for connecting installation tools. The operating part 320 provides a dedicated interface for installation tools (such as wrenches, screwdrivers, etc.), allowing operators to easily loosen or tighten the connector 300, and to achieve a large torque output with relatively small force, reducing physical exertion. By quickly positioning and using installation tools, the installation of multiple connectors 300 can be completed in a short time, significantly improving assembly efficiency.

[0050] like Figure 5 As shown, in one embodiment, the operating part 320 includes an operating hole 321. For example, the operating hole 321 is a countersunk hexagonal socket, so that the connecting member 300 can be tightened or loosened by applying a hexagonal wrench to the operating hole 321. In some embodiments, the locking member 400 may also be provided with an operating hole to facilitate screwing the locking member 400 in or out.

[0051] See Figure 5 As shown, in one embodiment, the operating part 320 includes an operating plane 322, which is located at the middle position of the connector 300. Tightening or loosening of the connector 300 can also be achieved by applying a tool, such as a wrench, to the operating plane 322.

[0052] like Figure 1 and Figure 3 As shown, in one embodiment, one of the first mounting base 100 and the second mounting base 200 is connected to a positioning detection element 500 for detecting the position of the other. For example, in the embodiment shown in the figures, the second mounting base 200 is provided with the positioning detection element 500 for detecting whether the first mounting base 100 is connected in place. In other embodiments, the first mounting base 100 may also be provided with the positioning detection element 500 for detecting whether the second mounting base 200 is connected in place. By providing the positioning detection element 500, it is possible to monitor in real time whether the first mounting base 100 and the second mounting base 200 are correctly installed in place. If they are not properly installed, an alarm signal can be output to remind the operator to handle the situation.

[0053] like Figure 1 As shown, in some embodiments, the position detection element 500 can be a proximity switch. Taking the proximity switch being disposed on the second mounting base 200 as an example, whether the proximity switch is in contact with the first mounting base 100 is used to determine whether the connection is in place. In some embodiments, the position detection element 500 can be a proximity sensor, which works based on the principle of electromagnetic induction and can sense the approach of a metal object, completing the detection task without physical contact.

[0054] like Figure 1 and Figure 3As shown, in one embodiment, one of the first mounting base 100 and the second mounting base 200 is provided with a positioning part 130, and the other is provided with a positioning hole 220 for engaging with the positioning part 130. For example, in the embodiment shown in the figures, the first mounting base 100 is provided with a protruding positioning part 130, and the second mounting base 200 is provided with a positioning hole 220. The design of the positioning part 130 and the positioning hole 220 ensures that the first mounting base 100 and the second mounting base 200 can be accurately aligned during assembly. Simultaneously, the positioning part 130 and the positioning hole 220 form a fixed connection point after engagement, increasing the rigidity and stability of the overall structure. Furthermore, the positioning part 130 and the positioning hole 220 provide clear assembly guidance, making the assembly process more intuitive and simple.

[0055] like Figure 1 and Figure 3 As shown, in one embodiment, the positioning hole 220 is configured as a through hole 221; the positioning part 130 is configured as a stepped shaft 131 that engages with the through hole 221. The stepped shaft 131 has a first diameter segment 1311 and a second diameter segment 1312, wherein the diameter of the first diameter segment 1311 is smaller than the diameter of the second diameter segment 1312, forming a stepped structure. The outer diameter of the first diameter segment 1311 is adapted to the inner diameter of the through hole 221, and the outer diameter of the second diameter segment 1312 is larger than the inner diameter of the through hole 221. The first diameter segment 1311 of the stepped shaft 131 can be inserted into the through hole 221, and is engaged and fixed by the second diameter segment 1312 engaging with the end face of the through hole 221, thereby connecting the first mounting base 100 and the second mounting base 200 together. In some embodiments, the second diameter segment 1312 of the stepped shaft 131 has a chamfered or rounded transition structure on the side near the mounting base to facilitate the guiding effect when the stepped shaft 131 is inserted into the through hole 221.

[0056] For example, in the appendix Figure 3 In the illustrated embodiment, the first mounting base 100 is configured with a stepped shaft 131, the central axis of which coincides with the central axis of the first mounting base 100. The second mounting base 200 is configured with a through hole, the central axis of which coincides with the central axis of the second mounting base 200. This arrangement enables the centering of the first mounting base 100 and the second mounting base 200, ensuring that components such as optical elements are in their optimal working position.

[0057] Furthermore, one embodiment of this application also provides a laser head (not shown), including an optical element and the clamping and positioning structure described above; the optical element is connected between a first mounting base and a second mounting base. By providing constraint forces in multiple directions through the connecting member and the locking member, the connection effect between the first mounting base and the second mounting base can be effectively improved, reducing the risk of relative movement or rotation between the first mounting base and the second mounting base, thereby improving the locking effect of the optical element connected between the first mounting base and the second mounting base, ensuring that the laser beam can efficiently and accurately complete the material processing task, and thus ensuring the processing quality.

[0058] In some embodiments, the optical element can be a collimating lens, which is used to convert the divergent beam emitted by the laser source into a parallel beam. By ensuring the locking effect of the collimating lens, it is guaranteed that the subsequent optical element receives a high-quality, low-divergence laser beam, laying the foundation for achieving high-precision processing.

[0059] In some embodiments, the optical element can be a focusing lens, which is used to focus the collimated parallel beam onto a very small point. By ensuring the locking effect of the focusing lens, the energy density of the laser is guaranteed, enabling the laser to generate sufficient heat on or inside the target material for operations such as cutting, welding, or marking.

[0060] In some embodiments, the optical element can be a protective lens, which, by ensuring the locking effect of the protective lens, prevents dust, debris or other contaminants from directly contacting the optical element such as the focusing lens.

[0061] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
