Description

Technical Field

[0001] This application relates to the field of optical equipment technology, and in particular to a high-precision fixing mechanism and clamping method. Background Technology

[0002] In modern precision optical systems, slender optical components such as quartz rods, due to their large aspect ratio, relatively brittle materials, and high requirements for dimensional accuracy and surface quality, typically need to be reliably fixed during assembly, testing, or long-term service. Existing clamping and fixing solutions mostly use mechanical clamps to position and lock the components. Common forms include lateral clamping, top clamping, end limiting, and using locating pins / locating surfaces to constrain the components. Some solutions also use elastic or soft contact components to reduce contact stress and achieve assembly positioning through screw adjustment.

[0003] The aforementioned clamping and fixing methods still have shortcomings when applied to slender, brittle, and surface-sensitive optical components: First, when the clamping load is concentrated in a local area of ​​the component or the assembly consistency is poor, it is easy to introduce unstable stress and deformation risks, and the clamping process is also prone to poor repeatability due to differences in operation; Second, on optical surfaces where contact needs to be avoided or minimized, clamping contact and assembly friction may bring risks such as contamination and scratches; Third, when it is necessary to simultaneously meet high positioning accuracy and assembly stability, traditional solutions often cannot balance adjustability, positioning reference clarity, and clamping retention, and are prone to position drift after clamping or repeated adjustments.

[0004] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Summary of the Invention

[0007] A base assembly and a clamping assembly, wherein the clamping assembly is detachably connected to the base assembly; The clamping assembly includes a clamping base, a first side plate and a second side plate disposed opposite to each other; the first side plate is fixedly connected to the clamping base, and the second side plate is adjustablely connected to the clamping base and can be locked.

[0015] Optionally, the threaded clamping element is an elastic set screw, and the elastic set screw has an elastic contact end.

[0016] As another aspect of the embodiments of this application, the embodiments of this application provide a clamping method applied to the fixing mechanism described above, the method comprising: The optical element is placed on the clamping base of the fixing mechanism and made to fit against the first side plate; Adjust the position of the second side plate and lock it in place so that the optical element is in contact with the second side plate; The cover plate is assembled and fastened to the second fixing hole through the first fixing hole; Tighten the elastic set screw to bring it into contact with and press it against the optical element.

[0017] The embodiments of this application employing the above-described technical solution may have the following advantages: This application provides a high-precision fixing mechanism and clamping method. The fixing mechanism includes a base assembly and a clamping assembly, with the clamping assembly detachably connected to the base assembly. The clamping assembly includes a clamping base, a first side plate, and a second side plate disposed opposite to each other. The first side plate is fixedly connected to the clamping base, and the second side plate is adjustablely connected to the clamping base and can be locked.

[0024] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0025] Please refer to the following: Figure 1 and Figure 2This application discloses a high-precision fixing mechanism in its first aspect, suitable for positioning and clamping slender, brittle, and surface-sensitive optical components such as quartz rods 25 during assembly, testing, or long-term service. The fixing mechanism includes a base assembly 1 and a clamping assembly 2 disposed on the base assembly 1, with the clamping assembly 2 detachably connected to the base assembly 1. By modularly configuring the clamping assembly 2 and detachably connecting it to the base assembly 1, it facilitates the transfer or replacement of the clamping module between different workstations. Furthermore, in scenarios involving repeated assembly and disassembly, it helps maintain consistent assembly references and reduces positional fluctuations caused by repeated clamping, thereby addressing the problems of poor clamping repeatability and the need for repeated adjustments in related technologies.

[0026] Specifically, please refer to the following: Figure 2 and Figure 4 The clamping assembly 2 includes a clamping base 21, a first side plate 22, and a second side plate 26 disposed opposite to each other. The first side plate 22 is fixedly connected to the clamping base 21, and the second side plate 26 is adjustablely connected to the clamping base 21 and can be locked. This configuration establishes a stable lateral reference relationship between the first side plate 22 and the clamping base 21, allowing the operator to use the fixed side plate as a stable contact surface when placing optical components, reducing initial positioning deviations caused by operational differences. Simultaneously, the second side plate 26 is adjustable before locking, enabling it to compensate for dimensional deviations or assembly errors in different batches of optical components. It is then locked in place after proper contact, thus creating a clearer division of labor and coordination between "adjustability" and "clamping retention," reducing the probability of position drift and repeated adjustments during clamping. This addresses the problem in related technologies where adjustability, reference clarity, and clamping retention are difficult to balance simultaneously.

[0027] Furthermore, the clamping base 21 can be provided with a support surface, on which the optical element is placed and forms a lateral constraint between the first side plate 22 and the second side plate 26. Through the cooperation of the support surface and the two side plates, the constraint of the element can be transformed from a single local point contact to a more stable surface / line contact combination, resulting in a more uniform load distribution and reducing the risk of stress and deformation introduced by concentrated local clamping loads. It should be noted that the support surface can be adapted according to the shape of the element: for example, a flat support, a V-groove support, or an arc-shaped support can be used; without changing the basic constraint relationship of support and lateral contact, the above support forms can be interchanged to adapt to round rods, square rods, or chamfered rod-shaped optical elements.

[0028] Furthermore, the clamping base 401 is also provided with a clearance groove. Specifically, the clearance groove extends along the length of the quartz rod 405 and is arranged adjacent to the supporting surface of the clamping base 401, so that the predetermined optical working surface of the quartz rod 405 in the clamped state is located within the space corresponding to the clearance groove and does not contact the clamping base 401. This arrangement can reduce contact and friction on sensitive surface areas during clamping, reduce the risk of contamination or scratches caused by assembly friction, and avoid unnecessary concentration of contact loads in local areas, thereby addressing the problems of easy contamination and scratches of optical surfaces and local concentration of clamping loads in related technologies. It should be noted that the cross-sectional shape of the clearance groove can be a rectangular groove, a circular arc groove, or a V-shaped groove. The clearance groove can also be set as a continuous groove or an intermittent groove according to the external dimensions of the quartz rod 405. As long as it can form a clearance space for the predetermined surface, it can be considered an equivalent replacement.

[0029] Furthermore, such as Figure 3 As shown, the base assembly 1 may be provided with a base locating pin hole 11 and a base screw hole 12. By simultaneously providing locating pin holes and screw holes on the base assembly 1, the locating structure can provide a reference constraint for repeated positioning during installation, and the screw connection can provide reliable clamping retention, so that the base assembly 1 still has good positional consistency after disassembly and assembly, thereby reducing the accumulation of overall clamping errors caused by installation reference drift. It should be noted that the number of locating pin holes and screw holes can be set to one or more sets according to the installation stability requirements; without changing the positioning constraint and fastening connection method, the locating structure can also be replaced with a locating key, a locating boss / groove fit, or a conical locating structure, etc.

[0030] Furthermore, the base assembly 1 may also be provided with a first mounting pin hole 13 and a second mounting pin hole 14 to facilitate the detachable connection between the clamping assembly 2 and the base assembly 1. By introducing two spaced-apart positioning relationships between the clamping assembly 2 and the base assembly 1, the anti-rotation constraint of the clamping assembly 2 relative to the base assembly 1 can be enhanced, the reset consistency after replacement or disassembly of the clamping module can be improved, thereby improving assembly stability and positioning accuracy. It should be noted that the first mounting pin hole 13 and the second mounting pin hole 14 can also be replaced with a pin-hole fit, a pin-groove fit, or a double-key positioning, depending on the structural space. As long as a clear installation reference can be provided and the relative attitude deviation can be limited, they can all be considered equivalent replacements.

[0031] Furthermore, the second side plate 26 may be provided with an adjusting pin hole 222 and an adjusting screw hole 221. A positioning pin is provided between the second side plate 26 and the clamping base 21, and the positioning pin cooperates with the adjusting pin hole 222. A fastener is provided between the second side plate 26 and the clamping base 21, and the fastener cooperates with the adjusting screw hole 221. With this configuration, the cooperation between the positioning pin and the adjusting pin hole 222 can provide repeatable guidance and positioning reference during the adjustment process, avoiding significant swaying of the second side plate 26 during adjustment, thereby making the adjustment of the lateral reference more controllable. The cooperation between the fastener and the adjusting screw hole 221 forms a reliable lock after being properly fitted, reducing positional drift caused by the second side plate 26 springing back or loosening during clamping. It should be noted that the adjusting pin hole 503 can be a round hole or an elongated hole: when the adjusting pin hole 503 is a round hole, the locating pin and the adjusting pin hole 503 form a relatively clear positioning fit, thereby limiting the relative position of the second side plate 406 and the clamping base 401 during assembly; when the adjusting pin hole 503 is an elongated hole, the locating pin and the adjusting pin hole 503 form a guiding fit, so that the second side plate 406 has an adjustable stroke in a predetermined direction, thereby facilitating position adjustment while maintaining guiding constraints. Furthermore, when the adjusting pin hole 503 is an elongated hole, the extension direction of the elongated hole can be consistent with the adjustment direction of the second side plate 406 to reduce wobble during the adjustment process. The above-mentioned round hole or elongated hole configuration can be selected according to the adjustment range and positioning accuracy requirements. In addition, the adjusting screw hole 221 can be a round hole or an elongated hole structure: when an elongated hole is used, a larger adjustable stroke can be provided to accommodate components of different sizes; when a round hole is used and an eccentric sleeve or eccentric bolt is used, micro-adjustment can also be achieved; without changing the adjustable and lockable connection principle, the above structure can be replaced according to the accuracy and adjustment range requirements.

[0032] Furthermore, the clamping assembly 2 also includes a cover plate 23 bridging the first side plate 22 and the second side plate 26. By setting the cover plate 23 to form a bridging constraint between the two side plates, it can play an overall stabilizing role in the relative position between the two side plates after lateral positioning, reducing structural opening or minor deformation caused by unilateral force, and thus improving the overall stability after clamping. It should be noted that the cover plate 23 can be replaced by a pressure beam, a connecting cross plate, or a frame-shaped pressure cover, etc.; as long as it can form a bridging between the two side plates and provide a stable connection, it can be considered an equivalent replacement.

[0033] Furthermore, the first side plate 22 is provided with a first fixing hole 261, and the second side plate 26 is provided with a second fixing hole 223. The cover plate 23 is connected to the first fixing hole 261 and the second fixing hole 223 by fasteners. By fastening the cover plate 23 to both side plates, a symmetrical or nearly symmetrical connection constraint can be formed, making the bridging of the cover plate 23 more stable and reducing the risk of off-center loading and loosening caused by single-point connection. It should be noted that the fastening connection can adopt screw connection, stud + nut connection, or quick-release locking part connection; without changing the hole position fit to achieve the fastening connection, the above fastening methods can be replaced according to assembly efficiency and anti-loosening requirements.

[0034] Furthermore, the cover plate 23 is provided with threaded holes, and a threaded clamping component is installed in the threaded holes. By tightening the threaded clamping component, a controllable clamping force can be applied while maintaining the two sides in contact with the reference, so that the optical element can be stably clamped and held, thereby reducing the risk of loosening caused by external disturbances or micro-vibrations during clamping. It should be noted that, in addition to the threaded set screw, the threaded clamping component can also be replaced with an eccentric clamping block, a wedge-shaped clamping block, or a clamping bolt with rollers, etc.; as long as it can provide an adjustable clamping force and form a reliable assembly relationship with the cover plate 23, it can be considered an equivalent replacement.

[0035] Furthermore, the threaded clamping component is an elastic set screw 24, which has an elastic contact end. By contacting the optical element through the elastic contact end, assembly errors and minor form and position differences can be elastically compensated during clamping, reducing the risk of scratches caused by contact stress concentration and hard contact friction. It also helps maintain a relatively consistent clamping state under different operators or different batches of components. The contact point of the elastic set screw 404 during clamping avoids the chamfered area of ​​the quartz rod 405. Specifically, the axial projection of the elastic set screw 404 intersects the non-chamfered outer cylindrical surface of the quartz rod 405, so that the elastic contact end falls on the non-chamfered outer cylindrical surface when contacting the quartz rod 405. This arrangement reduces the risk of scratches caused by interference or slippage between the elastic contact end and the chamfered edge, and makes the clamping load act more stably on the predetermined contact area. It should be noted that, without changing the requirement that the contact point avoid the chamfered area, the position of the elastic set screw 404 can also be adjusted by adjusting the position of the threaded hole on the cover plate 403 or by providing a ball-head structure at the end of the elastic set screw 404. It should be noted that the elastic contact end can take the form of an elastic rubber head, a spherical soft pad, a spring plunger end, or a film-coated end; the material can be polyurethane, fluororubber, silicone rubber, or nylon, etc., and can be replaced according to the requirements of cleanliness, hardness, and wear resistance without changing the elastic contact end's participation in the compression contact.

[0036] This application also discloses a clamping method in a second aspect, applied to the aforementioned fixing mechanism. The method includes: placing an optical element on a clamping base 21 and abutting it against a first side plate 22; adjusting the position of a second side plate 26 and locking it, so that the optical element is abutted against the second side plate 26; assembling a cover plate 23 and fastening it through a first fixing hole 261 and a second fixing hole 223; and screwing on an elastic set screw 24 to contact and press it against the optical element. This configuration first establishes a stable abutment reference with the fixed side plate, then completes the abutment and locking through the adjustable side plate, and finally achieves pressing and retention through a bridging structure and threaded clamping. This makes the sequence of positioning, adjustment, and locking processes clearer, reduces repeated position changes caused by clamping and alignment during the clamping process, thereby improving clamping consistency and reducing the need for repeated adjustments. Simultaneously, pressing contact through the elastic contact end reduces the risk of friction scratches and contamination during the pressing process, improving adaptability to surface-sensitive optical elements.

[0037] It should be noted that, without departing from the scope of the claims of this solution, the detachable connection of the clamping assembly 2 and the base assembly 1, the adjustable connection of the second side plate 26, the bridging connection of the cover plate 23, and the contact end of the elastic set screw 24 can all be replaced with equivalent ones to adapt to different installation spaces, optical elements of different shapes and sizes, and different cleanliness and assembly accuracy requirements.

[0038] In summary, the embodiments of this application provide a high-precision fixing mechanism and clamping method. The fixing mechanism includes a base assembly 1 and a clamping assembly 2. The clamping assembly 2 is detachably connected to the base assembly 1. The clamping assembly 2 includes a clamping base 21, a first side plate 22 and a second side plate 26 disposed opposite to each other. The first side plate 22 is fixedly connected to the clamping base 21, and the second side plate 26 is adjustablely connected to the clamping base 21 and can be locked. With this configuration, the fixed first side plate 22 provides a stable lateral reference during clamping, while the adjustable and lockable second side plate 26 positions and constrains the component, maintaining this relative position after locking. This reduces positioning fluctuations caused by operational differences during clamping and improves the consistency of repeated clamping. At the same time, the second side plate 26 can be adjusted before locking, allowing the positioning and clamping processes to be completed within the same structural system, reducing repeated adjustments and positional drift caused by clamping. In addition, the clamping assembly 2 and the base assembly 1 are detachably connected, maintaining a clear assembly reference relationship when adjustments, disassemblies, or tooling changes are required. This helps improve overall assembly stability and reduce the accumulation of errors introduced by repeated disassemblies and reassemblies.
