Description

Technical Field

[0001] This utility model relates to the field of lens processing, and more specifically, to a mirror processing angle positioning device. Background Technology

[0002] A mirror is an optical element that works based on the law of reflection. Mirrors can be classified into three types according to their shape: plane mirrors, spherical mirrors, and aspherical mirrors; and according to their degree of reflection: total reflection mirrors and semi-reflective mirrors. Because the law of reflection is independent of the frequency of light, this type of element has a very wide operating bandwidth, reaching the ultraviolet and infrared regions of the visible light spectrum, thus its applications are becoming increasingly widespread.

[0003] In the field of mirror manufacturing, the accuracy of angle positioning directly affects the final optical performance of the lens. However, existing mirror manufacturing positioning equipment has significant technical shortcomings. Most equipment uses a single clamping structure, which only simply fixes the edge of the mirror, lacking dual constraints on the lens angle. During processing, it is susceptible to angular deviation due to vibration, making it difficult to meet the requirements of high-precision processing. When clamped, the lens and the clamping components are mostly in rigid contact, resulting in high frictional resistance. This not only easily causes wear on the lens edge but also makes fine-tuning of the angle difficult, reducing processing efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a mirror processing angle positioning device, including two sets of clamping plates symmetrically clamping both sides of a mirror. The mirror can rotate horizontally between the two sets of clamping plates. A worktable is provided at the opening on one side of the two sets of clamping plates to connect the two sets of clamping plates. The two sets of clamping plates rotate horizontally on the worktable. A limiting member is provided at the opening on the other side of the two sets of clamping plates to fix and limit the two sets of clamping plates. Clamping rods are installed on the upper and lower surfaces of the worktable. A clamping drive member for driving the clamping rods passes through the worktable. The clamping rods are driven by the clamping drive member to act on the upper and lower surfaces of the mirror respectively, thereby limiting the horizontal rotation of the mirror.

[0005] In a preferred embodiment, both sets of clamping plates include clamping plates. The outer walls of the clamping plates in the two sets of clamping plates that are close to each other are provided with arc-shaped clamping grooves. Several balls are embedded in the clamping grooves. The surface of the balls matches the edge of the reflector. Limiting plates are provided at the top and bottom of the clamping grooves.

[0006] In a preferred embodiment, the limiting member includes a first connecting rod, which is fixed at the edge of the clamping plate away from the worktable. The end of the first connecting rod is equipped with a threaded half rod extending away from the reflector. The threaded half rods in the two sets of clamping plates are combined into a cylindrical shape and fitted with a fixing screw sleeve.

[0007] In a preferred embodiment, a first rotating shaft passes through one end of the clamping plate near the worktable, and an outwardly extending connecting plate is installed at the edge of the worktable. A first bearing is installed on the connecting plate, and the first rotating shaft is inserted into and fixed in the inner ring of the first bearing.

[0008] In a preferred embodiment, the clamping drive includes a second bearing embedded in the worktable and a drive motor mounted on the upper surface of the worktable. A rotating second shaft is inserted into the second bearing, and the two ends of the second shaft extend to the top and bottom of the worktable, respectively. The top end of the second shaft and the end of the output shaft of the drive motor are connected by a synchronous belt pulley.

[0009] In a preferred embodiment, the clamping rod includes a threaded tube sleeved outside the second rotating shaft. The outer wall of the second rotating shaft is provided with a thread that matches the threaded tube. A second connecting rod extending to one side of the reflector is installed outside the threaded tube. A clamping rod extending toward the surface of the reflector is installed at the end of the second connecting rod. A rubber gasket is installed at the end of the clamping rod.

[0010] In a preferred embodiment, a third connecting rod extending away from the second connecting rod is also installed outside the solenoid. A sleeve is installed at the end of the third connecting rod, and a limiting rod fixed to the surface of the worktable is inserted into the sleeve.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] This invention ensures precise and stable mirror processing angle through a dual limiting design of the clamping plate and clamping rod. The ball bearings in the clamping groove reduce friction between the lens and the groove, facilitating fine-tuning of the angle and protecting the lens edge. The rubber pad at the end of the clamping rod prevents scratches on the lens surface. The protective cover isolates processing impurities and ensures operational safety. At the same time, multiple bearings reduce component rotation friction, and the limiting rod ensures precise transmission. Overall, it balances processing convenience, workpiece protection, and equipment operational reliability. Attached Figure Description

[0018] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0019] like Figure 1-4 The illustrated reflector processing angle positioning device includes two sets of clamping plates symmetrically clamping both sides of a reflector 1. The reflector 1 can rotate horizontally between the two sets of clamping plates. A worktable 2 is provided at the opening on one side of the two sets of clamping plates to connect the two sets of clamping plates. The two sets of clamping plates rotate horizontally on the worktable 2. A limiting member is provided at the opening on the other side of the two sets of clamping plates to fix and limit the two sets of clamping plates. Clamping rods are installed on both the upper and lower surfaces of the worktable 2. A clamping drive member for driving the clamping rods passes through the worktable 2. The clamping rods are driven by the clamping drive member to act on the upper and lower surfaces of the reflector 1 respectively, thereby limiting the horizontal rotation of the reflector 1.

[0020] Based on the above, the two sets of clamping plates serve as the main load-bearing structure of the reflector 1. Their design allows for horizontal rotation on the worktable 2, facilitating clamping and installation of the reflector during processing. The limiting component is used to lock the position of the clamping plate to prevent it from shifting after angle adjustment. The clamping drive component provides power to the clamping rod, driving it to apply pressure from the upper and lower surfaces of the reflector 1, forming a rigid constraint on the horizontal rotation of the reflector 1. This prevents the reflector 1 from undergoing angular displacement due to vibration or external force during processing, ensuring the stability of the reflector 1's position during processing.

[0021] Both sets of clamping plates include clamping plates 3. The outer walls of the clamping plates 3 in the two sets of clamping plates are provided with arc-shaped clamping grooves 4. Several balls 24 are embedded in the clamping grooves 4. The surface of the balls 24 matches the edge of the reflector 1. Limiting pieces 5 are provided at the top and bottom of the clamping grooves 4.

[0022] Based on the above, the clamping plate 3 is the core support component of the clamping plate. The arc-shaped clamping groove 4 on its outer wall is adapted to the edge shape of the reflector 1, which can fit and wrap around the edge of the reflector 1, providing stable circumferential support for the reflector 1. The ball bearings 24 in the groove can convert the sliding friction between the reflector 1 and the clamping groove 4 into rolling friction, which reduces the wear of the edge of the reflector 1 when the angle is finely adjusted, and also reduces the rotational resistance of the reflector 1, so that the reflector 1 can rotate flexibly horizontally to adjust its own angle. The limiting pieces 5 at the top and bottom of the clamping groove 4 can axially limit the ball bearings 24 to prevent the ball bearings 24 from falling out of the clamping groove 4. At the same time, they can also limit the vertical displacement of the reflector 1, avoid vertical displacement of the reflector 1 when processing or adjusting the angle, and further ensure the positioning stability of the reflector 1.

[0023] The limiting component includes a first connecting rod 6, which is fixed at the edge of the clamping plate 3 away from the workbench 2. The end of the first connecting rod 6 is equipped with a threaded half rod 7 extending away from the reflector 1. The threaded half rods 7 in the two sets of clamping plates are combined into a cylindrical shape and fitted with a fixing screw sleeve 8.

[0024] Based on the above, the first connecting rod 6 serves as a connecting component, fixing the threaded half rod 7 to the clamping plate 3, so that the outer sides of the two sets of clamping plates are linked by the limiting component; the threaded half rod 7 on the two sets of clamping plates is designed as a "half rod" structure. When the two sets of clamping plates close to clamp the reflector 1, the two sets of threaded half rods 7 can be spliced ​​into a complete cylindrical structure. At this time, the fixing sleeve 8 is sleeved and tightened clockwise. The thread on the inner wall of the fixing sleeve 8 engages with the thread on the threaded half rod 7, generating an axial locking force, which firmly fixes the two sets of threaded half rods 7, thereby driving the two sets of clamping plates 3 to remain in a closed state, realizing the position locking of the clamping plates, and preventing the clamping plates from accidentally opening or shifting in angle during the processing of the reflector 1.

[0025] The clamping plate 3 has a first rotating shaft 9 passing through one end near the workbench 2. A connecting plate 10 extending outward is installed at the edge of the workbench 2. A first bearing 11 is installed on the connecting plate 10. The first rotating shaft 9 is inserted into and fixed in the inner ring of the first bearing 11.

[0026] Based on the above, the connecting plate 10 extends outward from the edge of the workbench 2 to provide a stable mounting carrier for the first bearing 11; the outer ring of the first bearing 11 is fixed to the connecting plate 10, and the inner ring is fixed to the first rotating shaft 9 that passes through the clamping plate 3. This kind of cooperation flexibly connects the clamping plate 3 and the workbench 2, which not only ensures that the first rotating shaft 9 can rotate synchronously with the clamping plate 3, but also reduces the frictional resistance when the clamping plate 3 rotates through the rolling characteristics of the bearing, so that the clamping plate 3 can easily rotate horizontally around the first rotating shaft 9.

[0027] The clamping drive includes a second bearing 12 embedded in the worktable 2 and a drive motor 13 mounted on the upper surface of the worktable 2. A rotating second shaft 14 is inserted into the second bearing 12. The two ends of the second shaft 14 extend to the top and bottom of the worktable 2, respectively. The top end of the second shaft 14 and the end of the output shaft of the drive motor 13 are connected by a synchronous belt pulley.

[0028] Based on the above, the drive motor 13 serves as a power source, and its output shaft is connected to the top of the second rotating shaft 14 via a synchronous pulley. When the drive motor 13 starts, the torque of the output shaft is transmitted to the second rotating shaft 14 via the synchronous pulley, causing the second rotating shaft 14 to rotate. The second bearing 12 embedded in the worktable 2 supports and limits the second rotating shaft 14, ensuring that the second rotating shaft 14 can rotate stably and limiting the radial displacement of the second rotating shaft 14, thus preventing the second rotating shaft 14 from shaking when rotating. The two ends of the second rotating shaft 14 extend to the upper and lower surfaces of the worktable 2, which can simultaneously provide power to the clamping rods on the upper and lower sides of the worktable 2, realize the synchronous action of the upper and lower clamping rods, ensure that the clamping force on the upper and lower surfaces of the reflector 1 is uniform, and prevent the reflector 1 from deforming or shifting its angle due to uneven clamping force.

[0029] The clamping rod includes a screw tube 15 sleeved outside the second rotating shaft 14. The outer wall of the second rotating shaft 14 is provided with a thread that matches the screw tube 15. A second connecting rod 16 extending to one side of the reflector 1 is installed outside the screw tube 15. A clamping rod 17 extending towards the surface of the reflector 1 is installed at the end of the second connecting rod 16. A rubber gasket 18 is installed at the end of the clamping rod 17.

[0030] Based on the above, the threads on the outer wall of the second rotating shaft 14 and the threads on the inner wall of the solenoid 15 are matched to form a helical transmission structure. The threads of the upper and lower sections of the second rotating shaft 14 on the worktable 2 are in opposite directions. When the second rotating shaft 14 rotates, it will drive the solenoid 15 to move axially along the second rotating shaft 14 through thread engagement. The upper and lower solenoids 15 will move closer or further apart. The solenoid 15 is connected to the clamping rod 17 through the second connecting rod 16. The axial movement of the solenoid 15 will synchronously drive the second connecting rod 16 and the clamping rod 17. Move towards or away from the reflector 1; when it is necessary to limit the reflector 1, the upper and lower solenoids 15 move closer to each other, and the solenoids 15 drive the clamping rod 17 to move towards the reflector 1 until the rubber pad 18 at the end of the clamping rod 17 is in contact with the surface of the reflector 1. The rubber pad 18 can prevent the clamping rod 17 from directly and rigidly contacting the surface of the reflector 1, preventing scratches on the coating or lens body of the reflector 1. At the same time, the elasticity of the rubber material can buffer the clamping force and prevent the reflector 1 from deforming due to excessive clamping force.

[0031] A third connecting rod 19 extending away from the second connecting rod 16 is also installed on the outside of the solenoid 15. A sleeve 20 is installed at the end of the third connecting rod 19, and a limiting rod 21 fixed to the surface of the worktable 2 is inserted into the sleeve 20.

[0032] Based on the above, since the limiting rod 21 is fixed, the sleeve 20 can only move along the axial direction of the limiting rod 21, thereby restricting the movement trajectory of the screw tube 15 and preventing the screw tube 15 from rotating synchronously with the second rotating shaft 14 when the second rotating shaft 14 rotates. This ensures that the screw tube 15 only moves in a straight line along the axial direction of the second rotating shaft 14. This design can ensure that the clamping rod 17 always moves closer to or further away from the reflector 1 in a fixed direction, avoiding the clamping rod 17 from shifting due to the rotation of the screw tube 15, which would prevent it from accurately acting on the surface of the reflector 1. This further improves the accuracy and stability of the clamping rod in limiting the reflector 1.

[0033] Protective covers 23 are installed on both the upper and lower surfaces of the worktable 2, covering the clamping rods and clamping drive components above and below the worktable 2 inside the protective covers 23, while the clamping rods 17 extend through the protective covers 23 to the reflector 1.

[0034] Based on the above, the protective cover 23 encloses the clamping rods (screw tube 15, second connecting rod 16, third connecting rod 19, sleeve 20, limit rod 21, clamping rod 17) and clamping drive components (second bearing 12, drive motor 13, second rotating shaft 14) on the upper and lower sides of the worktable 2. This effectively prevents debris, dust, and other impurities generated during the processing of the reflector 1 from entering the internal components, avoiding impurities adhering to the threads, bearings, or motor surfaces, which could affect the transmission accuracy and service life of the components. At the same time, the protective cover 23 can also prevent operators from accidentally touching rotating components (such as the second rotating shaft 14 and synchronous pulley) during equipment operation, thus improving the safety of equipment use. The design of the clamping rod 17 extending through the protective cover 23 to the reflector 1 ensures the protective function of the protective cover 23 without affecting the limiting function of the clamping rod 17 on the reflector 1, achieving a balance between protection and function.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of this utility model without creative effort should fall within the protection scope of this utility model.
