Description

Technical Field

[0001] This application relates to the field of clamping technology, and more specifically, to a clamping device and a light source device including the clamping device. Background Technology

[0002] Light source devices, such as mercury lamps used in precision industries like semiconductor manufacturing, typically require specialized clamping devices for installation and positioning. These clamping devices must not only provide a stable and reliable mechanical hold for the lamps but also ensure ease of operation when replacing them.

[0003] In related technologies, some clamping devices typically employ a fully enclosed or top-opening structure. When installing luminaires, the operator needs to insert the luminaire vertically from the top of the clamping device. For luminaires with leads, such as mercury lamps, this installation method often requires the operator to accurately align and pass the lead at the bottom of the luminaire body through the pre-drilled wire hole on the base of the clamping device while placing the luminaire body.

[0004] However, in practice, especially inside space-constrained equipment, simultaneously positioning the luminaire and aligning and threading the leads is cumbersome and time-consuming. Misalignment can lead to bent or damaged leads, affecting equipment reliability. Therefore, simplifying the luminaire installation process and improving installation and removal efficiency are pressing technical problems that need to be solved in this field.

[0011] In one embodiment, the fixed base is provided with a pivot groove, and one side of the opening and closing ring is integrally formed with a pivot lug that is adapted to the pivot groove, and the pivot lug is accommodated in the pivot groove.

[0012] In one embodiment, the pivoting mechanism further includes a pivot pin that passes through a pivot groove and is received therein, so that the opening and closing ring can rotate about the axis of the pivot pin.

[0013] In one embodiment, a locking groove is provided on the fixed base, and a locking notch corresponding to the locking groove is provided on the other side of the opening and closing ring; the locking mechanism includes a hinge bolt and a nut; wherein, one end of the hinge bolt is accommodated in the locking groove, and the other end of the hinge bolt can swing through the locking notch and engage with the thread of the nut to lock the opening and closing ring to the fixed base.

[0014] In one embodiment, the nut is a ram's horn nut.

[0015] In one embodiment, the locking mechanism further includes a locking pin; one end of the hinge bolt has a connecting hole; wherein the locking pin passes through the fixing seat and the connecting hole so that the hinge bolt can rotate about the axis of the locking pin.

[0021] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0022] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0023] The directional terms used in this description, such as "up," "down," "left," "right," "inner," and "outer," are only for reference to the directions shown in the attached diagram. These directional terms should be changed if the directions in the attached diagram change.

[0024] To better understand the technical solution of this application, the preferred embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0025] Please see Figure 1 The first aspect of this application provides a clamping device. In one specific embodiment, the clamping device includes a fixed base 100, an opening and closing ring 200 which is closably mounted on the fixed base 100, a pivoting mechanism 300 for connecting the fixed base 100 and the opening and closing ring 200, and a locking mechanism 400 for locking the opening and closing ring 200 to the fixed base 100.

[0026] The mounting base 100 is the base of the entire clamping device, used to fix the entire clamping device to an external device. Please refer to [reference needed]. Figure 2 A first receiving portion 110 is formed on the fixed base 100. The opening and closing ring 200 works in conjunction with the fixed base 100, and a second receiving portion 210 is formed on the opening and closing ring 200 to cooperate with the first receiving portion 110.

[0027] Specifically, one side of the opening / closing ring 200 is rotatably connected to the fixed base 100 via a pivoting mechanism 300, allowing the opening / closing ring 200 to rotate and open or close like a door around the axis of the pivoting mechanism 300. The other side of the opening / closing ring 200 is releasably locked to the fixed base 100 via a locking mechanism 400. When the opening / closing ring 200 is closed and locked by the locking mechanism 400, the first receiving portion 110 and the second receiving portion 210 together enclose the space, thereby defining a clamping space 211 for accommodating and fixing a workpiece (e.g., a lamp 500). When it is necessary to install or remove the workpiece, the locking mechanism 400 can be released and the opening / closing ring 200 can be rotated open. At this time, the clamping space 211 is fully opened from the side, forming an open channel to facilitate the insertion or removal of the workpiece.

[0028] Please refer to this application as well. Figures 2 to 3 ,in, Figure 2 yes Figure 1 An exploded view of the clamping device shown. Figure 3 yes Figure 1 The diagram shows the clamping device in a locked state at one angle.

[0029] In one embodiment, in order to effectively manage the heat of the clamped workpiece, a perforated heat dissipation channel is provided on the inner wall of the first receiving portion 110 or the second receiving portion 210. For example... Figure 3As shown, in this embodiment, a first hollow heat dissipation channel 111 is formed on the inner wall of the first receiving portion 110, and a second hollow heat dissipation channel 212 is also formed on the inner wall of the second receiving portion 210. These hollow heat dissipation channels, as through holes, increase the contact area between the clamping device and the surrounding air, and also provide a pathway for natural air convection. When the workpiece generates heat during operation, such as some high-power light source elements, the heat generated can be effectively conducted and convectioned away through these channels. Hot air can rise and dissipate through the channels, while surrounding cool air can enter to replenish it, thereby forming a heat dissipation cycle, preventing heat from accumulating at the clamped part of the workpiece, helping to maintain the stable working state of the workpiece and extend its service life.

[0030] In one embodiment, to further enhance the heat dissipation capability of the clamping device for fixing the workpiece, the first receiving portion 110 and the second receiving portion 210 together define at least one hollowed-out heat dissipation channel. See also... Figure 3 When the opening and closing ring 200 is closed and locked, a third hollow heat dissipation channel 213 and a fourth hollow heat dissipation channel 214 are formed at the joint edge of the first receiving part 110 and the second receiving part 210 by aligning the two through the preset notches.

[0031] This structural design allows heat dissipation channels to be distributed not only on the main bodies of the fixed base 100 and the opening / closing ring 200, but also cleverly utilizes the mating surfaces of the two components. These mating channels, combined with the aforementioned first hollowed-out heat dissipation channel 111 and second hollowed-out heat dissipation channel 212, form a wider and more three-dimensional heat dissipation channel around the clamped area of ​​the workpiece. This helps to create a more unobstructed airflow path, enabling the removal of heat generated by the clamped workpiece from multiple directions, achieving a more comprehensive and uniform heat dissipation effect.

[0032] In one embodiment, the structure of the fixed base 100 and the opening / closing ring 200 can be specifically designed to cooperate with the pivoting mechanism 300, as follows. Please refer to [link / reference]. Figure 2 A U-shaped pivot groove 120 is provided on one side of the fixing base 100. Correspondingly, Figure 2 In the middle, one side of the opening and closing ring 200 is integrally formed with a protruding pivot lug 220, the shape and size of which are adapted to the pivot groove 120 so that it can be smoothly inserted into the pivot groove 120.

[0033] In the assembled state, such as Figure 1As shown, the pivot lug 220 of the opening / closing ring 200 is housed within the pivot groove 120 of the fixed base 100. This groove-and-lug mating structure provides a structural basis for a stable rotational connection between the two. The aforementioned mating structure defines the relative positional relationship between the opening / closing ring 200 and the fixed base 100, ensuring that the opening / closing ring 200 can open and close along a preset trajectory during subsequent opening and closing movements.

[0034] In one embodiment, the pivoting mechanism 300 further includes a pivot pin 310. See also... Figure 2 The pivot pin 310 is a cylindrical pin. During assembly, the pivot pin 310 passes sequentially through the pivot groove 120 on the fixed seat 100 and the pivot lug 220 housed inside the pivot groove 120.

[0035] By assembling the pivot pin 310, the pivot lug 220 of the opening and closing ring 200 is fixed in the pivot groove 120 of the fixed seat 100, thereby enabling the opening and closing ring 200 to rotate axially around the pivot pin 310, thus realizing the opening and closing function of the clamping device.

[0036] Those skilled in the art will understand that the above-described embodiment, which achieves pivot connection through the cooperation of pivot groove 120, pivot lug 220, and pivot pin 310, is merely one specific embodiment of this application. Any other structural design that enables reliable connection between the opening / closing ring 200 and the fixed base 100 and allows rotation about a certain axis, such as the use of an integral rotating shaft, hinge structure, or flexible connector, is a simple variation of the technical solution of this application.

[0037] In one embodiment, the locking mechanism 400 can be specifically structurally designed. Please refer to [link / reference]. Figure 2 On the side of the fixed base 100 opposite to the pivot groove 120, a locking groove 130 is provided. Correspondingly, on the side of the opening and closing ring 200 opposite to the pivot ear 220, a U-shaped locking notch 230 is also provided.

[0038] The locking mechanism 400 may include a hinge bolt 410 and a nut. One end of the hinge bolt 410 is received within the locking groove 130 of the fixed seat 100 and forms a pivotal connection with the fixed seat 100. The other end of the hinge bolt 410 is a threaded rod. During the locking operation, the opening and closing ring 200 is first rotated to the closed position (see...). Figure 3 Then, the threaded shank of the hinge bolt 410 is passed through the locking notch 230 of the hinge ring 200. Subsequently, the nut is screwed onto the threaded shank of the hinge bolt 410 and tightened. By applying pressure to the hinge ring 200, the nut securely locks the hinge ring 200 onto the fixed seat 100, thereby completing the clamping of the workpiece.

[0039] To facilitate quick and manual tightening and loosening by operators, in one embodiment, a spur nut 420 is preferably selected. The spur nut 420 has a pair of wing-shaped knobs, allowing operators to easily tighten or loosen it without any tools, greatly improving ease of operation when changing workpieces.

[0040] In one embodiment, to enable the pivotal connection between the hinge bolt 410 and the fixed seat 100, the locking mechanism 400 may further include a locking pin 430. See also... Figure 2 The hinge bolt 410 has an annular head at one end, which is housed in the locking groove 130, and a connecting hole 411 is provided on the head.

[0041] During installation, first place the end of the hinge bolt 410 with the connecting hole 411 into the locking groove 130 of the fixed seat 100, aligning the connecting hole 411 with the pin hole on the side wall of the fixed seat 100. Then, insert the cylindrical locking pin 430 from the outside of the fixed seat 100, passing through the side wall of the fixed seat 100 and the connecting hole 411 of the hinge bolt 410 in sequence. With the installation of the locking pin 430, the hinge bolt 410 is rotatably mounted on the fixed seat 100. The locking pin 430 acts as a rotating shaft, allowing the hinge bolt 410 to swing freely around the axis of the locking pin 430, thus smoothly engaging or disengaging from the locking notch 230 of the opening and closing ring 200.

[0042] As will be understood by those skilled in the art, the locking mechanism 400 constructed by the cooperation of the locking groove 130, locking notch 230, hinge bolt 410, ram nut 420, and locking pin 430 is merely a preferred embodiment proposed in this application. Any other technical means that can releasably lock the free end of the opening ring 200 to the fixed seat 100 and achieve the same technical effect, such as using a snap-fit, cam locking, magnetic attraction, or pin structure, should be considered as an equivalent variation of the technical solution of this application.

[0043] In one embodiment, in order to securely mount the entire clamping device to an external device (such as the frame or panel of a machine), at least one mounting hole 140 is provided on the mounting base 100. These mounting holes 140 can be standard through holes, allowing the use of common fasteners such as bolts and screws to fix the mounting base 100 in a preset position.

[0044] Please see Figure 4In one specific embodiment, the mounting base 100 may have multiple mounting holes 140 to provide a more stable and reliable installation. For example, five mounting holes 140 may be provided, with four distributed at the four corners of the mounting base 100 and one located in the central area. This multi-point fixing layout can effectively resist vibrations and impacts from different directions, ensuring the positional accuracy and stability of the clamping device during operation.

[0045] Those skilled in the art will understand that the number, shape, and specific layout of the mounting holes 140 can be adjusted according to actual installation requirements and the interface of the external equipment. For example, three, four, or more mounting holes can be used, or strip-shaped holes can be used to facilitate fine-tuning of the position. Furthermore, the fixing method between the mounting base 100 and the external equipment is not limited to bolt connection. Any method that can achieve reliable fixing, such as welding, riveting, or using special clamps, falls within the scope of protection of this application.

[0046] The specific process of the clamping device provided in this application clamping the workpiece is as follows: First, if the clamping device is initially in Figure 3 In the closed locking state shown, the operator needs to grasp and rotate the swivel nut 420 on the locking mechanism 400. As the swivel nut 420 unscrews the thread of the hinge bolt 410, the clamping force of the locking mechanism 400 on the opening and closing ring 200 is gradually released. When the swivel nut 420 is fully loosened, the operator can swing the hinge bolt 410 outward to disengage it from the locking notch 230 on the opening and closing ring 200. At this time, the free end of the opening and closing ring 200 is released. Then, the operator can pull the opening and closing ring 200 to rotate it outward around the pivot pin 310, which serves as the rotation axis, until a fully open lateral passage for placing the workpiece is formed, such as... Figure 1 As shown.

[0047] Next, the operator can place the workpiece (e.g., lamp 500, see reference) Figure 5 The workpiece is horizontally placed into the first receiving portion 110 of the fixing base 100 from the side. This process does not require complex vertical alignment, and auxiliary structures such as the workpiece's lead wires can also be easily placed in place. After the workpiece is initially positioned, the operator needs to perform a reverse operation, rotating the opening and closing ring 200 inward around the pivot pin 310 until its second receiving portion 210 covers the other side of the workpiece. At this time, the first receiving portion 110 and the second receiving portion 210 together form a clamping space 211 for clamping the workpiece.

[0048] Finally, after the opening and closing ring 200 is closed in place, the operator needs to swing the hinge bolt 410 back so that its threaded shaft passes through the locking notch 230 of the opening and closing ring 200. Then, tighten the swivel nut 420. As the swivel nut 420 is screwed in, it will gradually press against the outer surface of the opening and closing ring 200, thereby firmly locking the opening and closing ring 200 onto the fixed seat 100, completing the reliable clamping of the workpiece.

[0049] As described above, the clamping device of this application exhibits the following beneficial effects through its structural design: On the one hand, the rotatable opening and closing ring 200 enables lateral installation of the workpiece. This installation method eliminates the need for operators to perform the cumbersome steps of aligning and threading the lead wires in traditional installation when installing workpieces with lead wires. This greatly simplifies the operation, significantly improves work efficiency, and effectively avoids the risk of damaging the workpiece during installation.

[0050] On the other hand, the multiple hollow heat dissipation channels provided on the first receiving portion 110 and the second receiving portion 210 provide an effective heat dissipation path for the heat generated by the workpiece during operation, which helps to maintain the performance stability of the workpiece.

[0051] A second aspect of this application provides a light source device. Please refer to... Figure 5 The light source device includes a lamp 500 and a clamping device for clamping the lamp 500.

[0052] It should be noted that the clamping device used in this light source device can be the clamping device described in detail in any of the foregoing embodiments, and its structure and function will not be repeated here. By using the clamping device of this application, the light source device can achieve convenient and quick operation when replacing the lamp 500.

[0053] It should be noted that the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0054] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
