Description

Technical Field

[0001] This utility model relates to the field of lens processing technology, and more specifically, it relates to a lens processing fixing device. Background Technology

[0002] Currently, in the manufacturing process of optical lenses, integrated tooling made of metal or plastic is commonly used to clamp and fix the lenses. However, due to the limitations of their material properties and overall structural design, these traditional toolings cannot adaptively match lenses with different curvatures or apertures, thus introducing clamping stress and deformation errors that are difficult to eliminate during processing.

[0003] Furthermore, existing lens fixing devices generally lack effective in-situ correction functions. During clamping, due to the lack of active positioning guidance, the lens often relies on the operator's experience for rough alignment, making it difficult to achieve precise alignment between the optical axis and the machine tool's rotation axis. This often results in positional deviations such as eccentricity and tilting after the lens is fixed, which not only reduces the angle control accuracy of the machining process but also affects the final optical performance and imaging quality of the optical element.

[0004] On the other hand, traditional fixing devices have relatively limited functionality, typically only providing basic clamping and unable to dynamically adjust the tilt angle and orientation of the lens according to the processing requirements. This limitation directly affects the adaptability and optimization potential of the processing technology, leading to reduced processing efficiency, difficulty in further improving surface quality, and an inability to meet the ever-increasing manufacturing requirements of high-precision, complex optical components.

[0005] In view of this, we propose a lens processing fixing device. Utility Model Content

[0006] (a) Technical problems to be solved In view of the problems existing in the prior art, the present invention provides a lens processing and fixing device to solve the technical problems mentioned in the background art.

[0007] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a lens processing and fixing device, comprising a base plate, a bracket fixedly connected to the base plate, a rotating sleeve rotatably connected to the bracket, a support block fixedly connected to the rotating sleeve, two rotating components rotatably connected to the support block, a motor fixedly connected to the bracket, a gear one fixedly connected to the output shaft of the motor, a gear two fixedly connected to the rotating sleeve, the gear two meshing with the gear one, a support sleeve slidably connected to the rotating sleeve, support plates evenly spaced fixedly connected to the support sleeve, guide rings fixedly connected to the support plates, and a centralizing structure and a fixing structure provided on the two rotating components.

[0008] The present invention is further configured such that the two rotating parts are jointly fixedly connected to a connecting frame, and the connecting frame is slidably connected to a ball-head rod.

[0009] The present invention is further configured such that the guide ring is provided with an annular limiting groove, and the ball head rod is slidably connected within the annular limiting groove of the guide ring.

[0010] The present invention is further configured such that the support sleeve is rotatably connected to a connecting ring, the bracket is fixedly connected to an electric push rod, and the telescopic end of the electric push rod is fixedly connected to the connecting ring.

[0011] The present invention is further configured such that the central structure includes a support platform, the support platform is fixedly connected to the two rotating members, the support platform is provided with equally spaced through grooves, and an extrusion block is slidably connected in the through groove.

[0012] The present invention is further configured such that a rotating ring is rotatably connected to the lower side of the support platform, the rotating ring is provided with inclined grooves distributed at equal intervals, the extrusion block is slidably connected in the adjacent inclined grooves, a fixed ring is fixedly connected to the rotating ring, and a torsion spring is fixedly connected between the fixed ring and the support platform.

[0013] The present invention is further configured such that the fixing structure includes a suction cup, the suction cup is embedded in the middle of the support platform, and a fixing shell is fixedly connected to the lower side of the support platform, the fixing shell being in communication with the suction cup.

[0014] The present invention is further configured such that a piston is slidably connected in a sealed manner inside the fixed shell, a spring is fixedly connected between the piston and the fixed shell, an electric push rod II is fixedly connected to the bracket, and a pull rope is fixedly connected between the telescopic end of the electric push rod II and the piston.

[0015] (III) Beneficial Effects Compared with the prior art, the present invention provides a lens processing and fixing device, which has the following beneficial effects: 1. This utility model achieves automatic lens alignment through a centrally located structure. After the lens is placed, the operator only needs to rotate the fixing ring, which drives the three pressing blocks to move synchronously towards the center via the tilting groove on the rotating ring. This clamps the lens evenly from three directions, ensuring that its central axis precisely coincides with the central axis of the suction cup. This reduces eccentricity and tilting errors caused by human factors, providing a reliable positioning reference for subsequent high-precision processing, and improving surface accuracy and product yield.

[0016] 2. This invention uses an electric push rod to pull a piston, creating negative pressure within the suction cup, which then adheres to the lens surface. This fixing method avoids the clamping stress and surface scratches that may occur with traditional metal clamps, making it particularly suitable for brittle optical materials.

[0017] 3. The electric push rod of this utility model can adjust the lens to any desired tilt angle by pushing the support sleeve, which, through the cooperation of the guide ring and the ball joint, can also drive the entire support platform and the lens to rotate precisely in the circumference via a gear set. This combination of multi-angle oscillation and rotation improves the processing effect and surface quality. Attached Figure Description

[0023] Please see Figures 1-5A lens processing and fixing device includes a base plate 1, a bracket 2 fixedly connected to the base plate 1, a rotating sleeve 3 rotatably connected to the bracket 2, a support block 4 fixedly connected to the rotating sleeve 3, two rotating parts 5 rotatably connected to the support block 4, a motor 6 fixedly connected to the bracket 2, a gear 7 fixedly connected to the output shaft of the motor 6, a gear 8 fixedly connected to the rotating sleeve 3, the gear 8 meshing with the gear 7, a support sleeve 9 slidably connected to the rotating sleeve 3, support plates 10 evenly spaced and fixedly connected to the support sleeve 9, a guide ring 11 fixedly connected to the support plate 10, a centering structure and a fixing structure provided on the two rotating parts 5; a connecting frame 12 fixedly connected to both rotating parts 5, a ball head rod 13 slidably connected to the connecting frame 12; an annular limiting groove provided on the guide ring 11, the ball head rod 13 slidably connected within the annular limiting groove of the guide ring 11; a connecting ring 14 rotatably connected to the support sleeve 9, an electric push rod 15 fixedly connected to the bracket 2, the telescopic end of the electric push rod 15 fixedly connected to the connecting ring 14.

[0024] Please see Figure 2 and Figure 3 The central structure includes a support platform 16, which is fixedly connected to two rotating parts 5. The support platform 16 is provided with equally spaced through slots 17, and an extrusion block 18 is slidably connected in the through slots 17. A rotating ring 19 is rotatably connected to the lower side of the support platform 16. The rotating ring 19 is provided with equally spaced inclined slots 20. The extrusion block 18 is slidably connected in adjacent inclined slots 20. A fixing ring 21 is fixedly connected to the rotating ring 19. A torsion spring 22 is fixedly connected between the fixing ring 21 and the support platform 16.

[0025] Please see Figure 4 and Figure 5 The fixing structure includes a suction cup 23, which is embedded in the middle of the support platform 16. A fixing shell 24 is fixedly connected to the lower side of the support platform 16 and is connected to the suction cup 23. A piston 25 is sealed and slidably connected inside the fixing shell 24. A spring 26 is fixedly connected between the piston 25 and the fixing shell 24. An electric push rod 27 is fixedly connected to the bracket 2. A pull rope 28 is fixedly connected between the telescopic end of the electric push rod 27 and the piston 25.

[0026] The working principle of this utility model: The lens is placed on the support platform 16, and then the fixing ring 21 is rotated. The fixing ring 21 drives the rotating ring 19 to rotate along the support platform 16. The torsion spring 22 is tightened. The rotating ring 19 drives the extrusion block 18 to slide along the through groove 17 through the inclined groove 20. The three extrusion blocks 18 move closer to each other and extrude the lens, thereby correcting the position of the lens and making the central axis of the lens coincide with the central axis of the suction cup 23, thereby improving the accuracy of subsequent processing.

[0027] Loosen the retaining ring 21. Under the action of the torsion spring 22, the rotating ring 19 returns to its original position, and the three pressing blocks 18 also return to their original position, without affecting the lens processing. Then, start the electric push rod 27. The telescopic end of the electric push rod 27 pulls the piston 25 downward through the pull rope 28. The piston 25 moves downward along the fixed shell 24, thereby creating a negative pressure state between the suction cup 23 and the lens. The suction cup 23 then adsorbs the lens, thereby improving the stability of the lens during processing. As the piston 25 moves downward, the spring 26 is compressed.

[0028] When the tilt angle of the lens needs to be changed, the electric push rod 15 is activated. The telescopic end of the electric push rod drives the support sleeve 9 downward through the connecting ring 14. The support sleeve 9 drives the guide ring 11 downward. The annular limiting groove of the guide ring 11 causes the ball head rod 13 to swing downward. The ball head rod 13 drives the two rotating parts 5 to rotate along the support block 4 through the connecting frame 12, thereby causing the support platform 16 and the lens on it to swing, changing the tilt angle of the lens. When the lens needs to rotate circumferentially at a specific angle, the motor 6 is activated. The output shaft of the motor 6 drives the gear 8 through the gear 17. The rotating sleeve 3 drives the support platform 16 to rotate through the support block 4 and the rotating parts 5. During the above process, the pull rope 28 is always taut. Through the cooperation of the motor 6 and the electric push rod 15, the lens can swing at multiple angles during processing, improving the processing effect of the lens.

[0029] After processing is completed, the telescopic end of the control electric push rod 27 is reset, and under the elastic force of the spring 26, the piston 25 is reset, the suction cup 23 releases its adsorption on the lens, and the lens is removed from the support table 16.

[0030] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
