Description

Technical Field

[0001] This utility model relates to the field of optical lens processing technology, and in particular to a shock-absorbing base for a high-stability optical lens processing platform. Background Technology

[0002] The high-stability optical lens processing platform vibration damping base is a precision system specifically designed to provide an ultra-stable mounting foundation for optical lens processing equipment. Its core function is to act as a highly efficient "vibration filter," completely isolating the upstream processing equipment from the downstream external environment where various interferences exist, thereby creating a near-"dynamically static" purified working space. This extreme stability is the fundamental prerequisite for ensuring that optical lenses achieve nanometer or even sub-nanometer level processing precision and surface quality.

[0003] These types of bases, designed for ultimate stability, typically have a fixed working height. Since precision machining and inspection operations require operators to maintain close-range, highly focused observation and operation for extended periods, fixed-height platforms cannot accommodate the individual needs of operators of different heights. This can easily force employees to adopt unnatural postures such as bending over or peering over. Such prolonged static and poor postures not only accelerate operator fatigue and distract their attention but may also lead to occupational strain on the musculoskeletal system, ultimately affecting work efficiency and continuity, and even introducing potential precision risks to the machining process due to poor human condition. Utility Model Content

[0004] The purpose of this invention is to provide a shock-absorbing base for a highly stable optical lens processing platform, in order to solve the problem mentioned in the background art that the existing fixed-height platforms cannot adapt to the personalized needs of operators of different heights, and are very likely to force employees to adopt unnatural postures such as bending over and craning their necks to work. Such long-term static poor postures will not only accelerate the operator's physical fatigue and distract their attention, but may also cause occupational strain of muscles and bones, ultimately affecting the efficiency and continuity of work, and even introducing potential accuracy risks to the processing process due to poor human condition.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-stability optical lens processing platform shock-absorbing base, including a base frame and a shock-absorbing base body, wherein the base frame is provided with a lifting structure, the lifting structure is provided with a pair of limiting structures, and the shock-absorbing base body is provided with a lifting rod, the lifting rod being movably connected to the base frame; The lifting structure includes a connecting plate mounted on the base frame. A lifting frame is movably mounted on the connecting plate, and a rotating frame is movably mounted on the connecting plate. A rotating pulley is mounted on the rotating frame, and a rotating threaded rod is movably mounted on the rotating frame and connected to the lifting frame. A motor is mounted on the connecting frame, and a rotating pulley is mounted on the drive end of the motor. A transmission belt is mounted on the rotating pulley and the rotating pulley.

[0006] Preferably, the motor is fixed to the connecting frame by bolts, and the lifting frame is adapted to the connecting plate.

[0007] Preferably, the base frame is provided with support legs, and the connecting frame is provided with reinforcing ribs.

[0008] Preferably, one of the pair of limiting structures includes a fixed frame, which is mounted on the connecting plate. A movable frame is movably mounted on the fixed frame and connected to the lifting frame. The movable frame has a limiting groove. The fixed frame has an mounting frame. A sliding block is movably mounted on the mounting frame. A rotating threaded rod is movably mounted on the mounting frame and connected to the sliding block. A support frame is mounted on the mounting frame. A rotating frame is movably mounted on the support frame. A movable wheel is movably mounted on the rotating frame and abuts against the sliding block.

[0009] Preferably, the limiting groove is provided in a plurality of parts, and the rotating threaded rod is provided with a rotating handle at the end away from the sliding block.

[0010] Preferably, the limiting groove is adapted to the rotating frame, and the sliding block is adapted to the mounting frame.

[0011] Preferably, the movable frame is adapted to the fixed frame, and the mounting frame is provided with reinforcing ribs.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This high-stability optical lens processing platform shock-absorbing base, through a set lifting structure, is driven by a motor and transmitted smoothly and with low vibration to the rotating threaded rod via a transmission system consisting of pulleys and a transmission belt. Finally, the lifting frame achieves precise lifting and lowering of the shock-absorbing base body. The entire process has a clear transmission chain and smooth operation, effectively realizing flexible and controllable adjustment of the base height, significantly improving the equipment's adaptability to different working scenarios and the personalized needs of operators, while ensuring stability and reliability during the lifting process.

[0013] 2. This high-stability optical lens processing platform shock-absorbing base, through the setting of a limiting structure, uses a rotating threaded rod to drive a sliding block and a rotating frame to form a linkage mechanism, which accurately converts the rotational motion into radial displacement at one end of the rotating frame, so that it can be reliably embedded in the corresponding limiting groove of the moving frame. This achieves rapid and secure locking of the lifting frame and shock-absorbing platform at any preset height, effectively preventing possible sinking or displacement during operation, and ensuring the positioning accuracy and stability of the equipment during long-term operation.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a technical solution: a high-stability optical lens processing platform shock-absorbing base, including a base frame 1 and a shock-absorbing base body 5. The base frame 1 is provided with a lifting structure 2, the lifting structure 2 is provided with a pair of limiting structures 3, and the shock-absorbing base body 5 is provided with a lifting rod 4, which is movably connected to the base frame 1. The lifting structure 2 includes a connecting plate 201, which is mounted on the base frame 1. A lifting frame 202 is movably mounted on the connecting plate 201. A rotating frame 203 is movably mounted on the connecting plate 201. A rotating pulley 204 is mounted on the rotating frame 203. A rotating threaded rod 205 is movably mounted on the rotating frame 203 and connected to the lifting frame 202. A connecting frame 206 is mounted on the connecting plate 201. A motor 207 is mounted on the connecting frame 206. A rotating pulley 208 is mounted on the driving end of the motor 207. A transmission belt is mounted on the rotating pulley 204 and the rotating pulley 208. 209. There are four lifting rods 4, symmetrically arranged in pairs on the base frame 1. The four lifting rods 4 can stabilize the shock-absorbing base body 5 when it moves. The lifting frame 202 is connected to the shock-absorbing base body 5. When it is necessary to adjust the height of the shock-absorbing base body 5, the drive motor 207 is used. The motor 207 can drive the rotating pulley 208 to rotate. The transmission belt 209 drives the rotating pulley 204 to rotate under the action of the rotating pulley 208. The rotating pulley 204 can drive the rotating frame 203 to rotate. The rotating frame 203 can drive the rotating threaded rod 205 to rotate and move. The rotating threaded rod 205 can drive the lifting frame 202 to move. The lifting frame 202 can drive the shock-absorbing base body 5 to move.

[0017] Furthermore, the motor 207 is fixed to the connecting frame 206 by bolts. This connection method not only provides a stable mechanical interface for the motor 207, ensuring the stability of power output, but also significantly optimizes the maintainability of the equipment. When maintenance, replacement, or debugging is required, operators can quickly complete the disassembly and assembly operations with the help of standard tools, greatly simplifying the process and improving the overall efficiency of equipment operation and maintenance. The lifting frame 202 is adapted to the connecting plate 201, and adopts a precision fitting design. The cooperation relationship between the two has been rigorously calculated and optimized, effectively constraining the degree of freedom during the movement. This highly compatible structure ensures that the lifting frame 202 can move smoothly and without jamming on the guide trajectory of the connecting plate 201, thereby controlling the movement error within a minimum range and laying a solid foundation for the precise lifting and long-term reliability of the entire platform.

[0018] Furthermore, the base frame 1 is equipped with support legs. This design not only effectively adapts to different ground conditions at different work sites and ensures that the base frame 1 is placed horizontally through fine adjustments, but also significantly enhances its contact stability with the foundation plane. This effectively suppresses minor shaking that may be caused by external forces or the operation of the equipment itself, thus building a solid and reliable foundation for the entire shock-absorbing platform. The connecting frame 206 is equipped with reinforcing ribs. This design significantly improves the structural rigidity and load-bearing capacity of the connecting frame 206, enabling it to suppress its own deformation to the maximum extent when bearing the vibration and torque generated by the operation of the motor 207. This ensures the accuracy and smoothness of power transmission and ultimately enhances the comprehensive mechanical performance and long-term durability of the entire lifting transmission system.

[0019] Furthermore, one of the pair of limiting structures 3 includes a fixed frame 301, which is mounted on the connecting plate 201. A movable frame 302 is movably mounted on the fixed frame 301 and connected to the lifting frame 202. The movable frame 302 has a limiting groove 303. A mounting frame 304 is mounted on the fixed frame 301. A sliding block 305 is movably mounted on the mounting frame 304. A rotating threaded rod 306 is movably mounted on the mounting frame 304 and connected to the sliding block 305. A support frame 307 is mounted on the mounting frame 304. A rotating frame 308 is movably mounted on the support frame 307. A movable wheel 309 is movably mounted on the rotating frame 308 and connected to the lifting frame 202. When the sliding block 305 abuts and the height of the shock-absorbing platform needs to be fixed and limited, the movable frame 302 can move on the fixed frame 301 along with the lifting frame 202. After the shock-absorbing platform on the lifting frame 202 moves to the predetermined position, the rotating threaded rod 306 is rotated. Rotating the threaded rod 306 can drive the sliding block 305 to slide on the mounting frame 304. The movable wheel 309 rotates on the sliding block 305, and the rotating frame 308 rotates on the support frame 307. At this time, one end of the rotating frame 308 with the movable wheel 309 moves away from the mounting frame 304, and the other end of the rotating frame 308 moves closer to the mounting frame 304 until the other end of the rotating frame 308 away from the movable wheel 309 enters the limiting groove 303 on the movable frame 302, thereby fixing and limiting the lifting frame 202.

[0020] Furthermore, the limiting groove 303 is provided in several places, so that the rotating frame 308 can flexibly select and embed itself in the limiting groove 303 of different heights according to the actual stroke and working position of the lifting frame 202. This achieves precise and reliable fixation of the lifting frame 202 in multiple predetermined positions, effectively preventing unexpected displacement during operation and ensuring the safety and stability of equipment operation. The rotating threaded rod 306 is provided with a rotating handle at the end away from the sliding block 305. This component provides the operator with a significant force-saving lever and a convenient force application point, making the operation of driving the sliding block 305 to make precise and controllable linear movement by rotating the threaded rod 205 more labor-saving and efficient, greatly improving the operational convenience and overall human-machine interaction experience during equipment adjustment.

[0021] Furthermore, the limiting groove 303 is adapted to the rotating frame 308 and adopts a high-precision matching contour design to ensure that the rotating frame 308 can achieve surface contact rather than point contact when embedded in the groove. This greatly enhances the structural rigidity and impact resistance during locking, preventing it from shaking or dislodging when subjected to loads from the lifting frame 202. It achieves absolute fixation and safe support at any preset height. The sliding block 305 is adapted to the mounting frame 304, enabling the sliding block 305 to move smoothly and linearly along a predetermined trajectory under the drive of the transmission threaded rod. This minimizes shaking and deviation during operation and provides excellent guiding accuracy and repeatability reliability for the entire lifting process.

[0022] Furthermore, the movable frame 302 is adapted to the fixed frame 301 and coupled to each other through a precise sliding fit structure. This highly compatible design ensures that when the movable frame 302 moves on the guide rail of the fixed frame 301, it can effectively suppress lateral sway and pitch deviation, thereby achieving smooth, stable and jam-free linear displacement. This provides a highly reliable moving reference and long-term operational stability for the entire limiting mechanism. The mounting frame 304 is provided with reinforcing ribs. These rib structures, optimized by finite element analysis, can significantly improve the bending and torsional stiffness of the mounting frame 304, enabling it to effectively suppress elastic deformation when subjected to cyclic forces from the sliding block 305 and the rotating threaded rod 306, thereby ensuring transmission accuracy and extending the fatigue life of the structural components.

[0023] Working principle: When the shock-absorbing base body 5 needs to be raised or lowered, the drive motor 207 is activated. The motor 207 drives the rotating pulley 208 to rotate. The transmission belt 209, under the action of the rotating pulley 208, drives the rotating pulley 204 to rotate. The rotating pulley 204 drives the rotating frame 203 to rotate. The rotating frame 203 drives the rotating threaded rod 205 to rotate and move. The rotating threaded rod 205 drives the lifting frame 202 to move. The lifting frame 202 drives the shock-absorbing base body 5 to move. When the height of the shock-absorbing platform needs to be fixed and limited, the moving frame 302 can move on the fixed frame 301 along with the lifting frame 202. After the shock-absorbing platform on the lifting frame 202 moves to the predetermined position, the threaded rod 306 is rotated. Rotating the threaded rod 306 can drive the sliding block 305 to slide on the mounting frame 304. The moving wheel 309 rotates on the sliding block 305, and the rotating frame 308 rotates on the support frame 307. At this time, one end of the rotating frame 308 with the moving wheel 309 moves away from the mounting frame 304, and the other end of the rotating frame 308 moves closer to the mounting frame 304 until the other end of the rotating frame 308 enters the limiting groove 303 on the moving frame 302, thereby fixing and limiting the lifting frame 202.

[0024] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
