Description

Technical Field

[0001] This utility model belongs to the field of lens processing technology, and in particular relates to a lens grinding device for optical instrument processing. Background Technology

[0002] Optical instruments are composed of one or more optical components. They are mainly divided into two categories: one is optical instruments that form real images, such as slide projectors and cameras, and the other is optical instruments that form virtual images, such as telescopes, microscopes, and magnifying glasses. During the production process, the lenses of optical instruments need to be polished. However, existing lens polishing equipment still has some problems.

[0003] For example, the utility model patent with publication number CN222520832U includes a base, a gantry frame on the top of the base, a receiving box inside the gantry frame, a moving component inside the receiving box, vertical plates on both sides of the inner wall of the gantry frame, and an adjustment component on one side of the vertical plate.

[0004] When the grinding wheel comes into contact with the lens, it generates a continuous, vertically downward, high-frequency alternating pressure, accompanied by strong vibrations. The clamping mechanism of this utility model lacks buffering capacity, and the vibrations are directly transmitted to the lens. The vibration energy continues to accumulate inside the lens, which may lead to lens breakage. Utility Model Content

[0005] The purpose of this invention is to provide a lens polishing device for optical instrument processing. By setting up a clamping assembly, specifically by starting a motor to drive a lead screw to rotate between two support blocks, and by setting two opposite threads on the lead screw, two sliders drive two clamping blocks to move in opposite directions, thus clamping and fixing the lens. During the polishing process, the soft pad, damping rod and spring work together to allow the clamping blocks to produce slight elastic displacement when subjected to downward pressure, thereby effectively absorbing and buffering the downward impact force and vibration, reducing the risk of lens breakage, and solving the problem that the clamping mechanism of existing lens polishing equipment lacks buffering capacity, which may lead to lens breakage.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a lens grinding device for optical instrument processing, comprising an operating table, a clamping assembly, and a grinding assembly.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0035] Please see Figures 1-5 As shown, this utility model has the following two specific embodiments.

[0036] Example 1

[0037] This utility model relates to a lens grinding device for optical instrument processing, comprising an operating table 1, a clamping assembly 2, and a grinding assembly 3. The clamping assembly 2 is mounted on the top of the operating table 1 and is used to clamp and fix the lens. The clamping assembly 2 includes:

[0038] Two support blocks 21 are fixedly connected to the top of the operating table 1. A lead screw 211 is rotatably connected to one side of the two support blocks 21. The threads on the outer surface of the lead screw 211 are set in two opposite directions. Two sliders 212 are connected to the threads on the outer surface of the lead screw 211.

[0039] Motor 213 is fixedly connected to the top of the control panel 1. The right output end of motor 213 is fixedly connected to the left side of lead screw 211.

[0040] Clamping block 22 is installed above slider 212. A damping rod 221 is fixedly connected to the bottom of clamping block 22. The bottom of damping rod 221 is fixedly connected to the top of slider 212. A spring 222 is sleeved on the outer surface of damping rod 221.

[0041] Placement platform 23 is fixedly connected to the top center of the worktable 1, and a soft pad 231 is fixedly connected to the top of the placement platform 23.

[0042] The polishing component 3 is mounted above the clamping component 2 and is used to polish the lens.

[0043] like Figures 1-3 As shown, by setting the clamping assembly 2, specifically by starting the motor 213, the lead screw 211 is driven to rotate between the two support blocks 21. Since the lead screw 211 has two opposite threads, the two sliders 212 drive the two clamping blocks 22 to move in opposite directions, clamping and fixing the lens. During the polishing process, the soft pad 231, the damping rod 221 and the spring 222 cooperate to allow the clamping blocks 22 to produce slight elastic displacement when subjected to downward pressure, thereby effectively absorbing and buffering the downward impact force and vibration, reducing the risk of lens breakage.

[0044] Two guide rails 214 are fixedly connected to the top of the control panel 1, and the outer surface of the guide rails 214 is slidably connected to the bottom of the slider 212.

[0045] Rubber pads 223 are fixedly connected to the corresponding sides of the two clamping blocks 22.

[0046] The guide rail 214 provides precise guidance for the movement of the slider 212, preventing the slider 212 from shifting or wobbling during movement, thus improving the accuracy and stability of lens clamping and positioning; the rubber pad 223 can effectively increase friction to ensure firm clamping, while avoiding scratches or indentations that may be caused by the hard clamping block 22 directly contacting the lens surface.

[0047] Example 2

[0048] Grinding component 3 includes:

[0049] Support frame 31 is fixedly connected to the top of the operating table 1. An electric push rod 311 is fixedly connected to the top of the support frame 31, and a connecting frame 312 is fixedly connected to the bottom output end of the electric push rod 311.

[0050] Motor 2 32 is fixedly connected to the left side of the connecting frame 312, and the bottom output end of motor 2 32 is fixedly connected to the mounting groove 321;

[0051] Grinding wheel 322 is installed at the bottom of mounting groove 321. A plug 323 is fixedly connected to the top of grinding wheel 322 and the plug 323 is inserted into the inner wall of mounting groove 321.

[0052] Two threaded holes 324 are respectively opened inside the insert block 323 and the mounting groove 321, and the two threaded holes 324 are threaded with fixing bolts.

[0053] like Figures 4-5As shown, by setting the mounting slot 321, when it is necessary to replace the grinding wheel 322, the fixing bolt can be unscrewed from the threaded hole 324 to remove the grinding wheel 322. The same applies during installation. The insert block 323 is inserted into the inner wall of the mounting slot 321, and then the fixing bolt is tightened into the inner wall of the threaded hole 324. This meets the needs of quickly replacing the grinding wheel 322 after different lens profiles or wear, and improves the maintenance efficiency of the equipment.

[0054] Two limiting rods 313 are fixedly connected to the top of the connecting frame 312, and the outer surface of the limiting rods 313 is slidably connected to the top of the support frame 31.

[0055] A suction port 33 is fixedly connected to the right side of the connecting frame 312, a suction pipe 331 is fixedly connected to the top of the suction port 33, a vacuum cleaner 332 is fixedly connected to the top of the operating table 1, and the top of the vacuum cleaner 332 is fixedly connected to the side of the suction pipe 331 away from the suction port 33.

[0056] The limiting rod 313 provides additional vertical guidance and support for the connecting frame 312, effectively preventing the connecting frame 312 from rotating or shifting laterally during lifting, thus improving the accuracy and stability of the grinding process. The dust suction port 33, together with the dust suction pipe 331 and the vacuum cleaner 332, can efficiently extract and collect the dust and debris generated during grinding, effectively preventing dust from spreading and polluting the working environment and lens surface, and protecting the health of operators.

[0057] A specific application of this embodiment is as follows: In use, the lens is placed on the soft pad 231 on top of the placement platform 23. The motor 213 is started, driving the lead screw 211 to rotate between the two support blocks 21. Due to the two opposite threads of the lead screw 211, the two sliders 212 drive the two clamping blocks 22 to move in opposite directions, clamping and fixing the lens. Then, the electric push rod 311 is started, pushing the connecting frame 312 to drive the grinding wheel 322 to descend. The motor 32 is started, driving the mounting groove 321 and the grinding wheel 322 to rotate for grinding. During the grinding process, the soft pad 231, damping rod 221, and spring 222 cooperate to allow the clamping blocks 22 to produce slight elastic displacement when subjected to downward pressure, thereby effectively absorbing and buffering the vertical downward force from the grinding wheel 322. To reduce the risk of lens breakage, the slider 212 slides on the outer surface of the guide rail 214 while the clamping block 22 moves. Simultaneously, the limiting rod 313 slides on the top of the support frame 31 while the grinding wheel 322 moves. The guide rail 214 and the limiting rod 313 provide stable movement trajectories for the clamping block 22 and the grinding wheel 322, preventing deviation or jamming during movement. During grinding, the vacuum cleaner 332 is activated, collecting debris generated during grinding through the suction pipe 331 and suction port 33. When the grinding wheel 322 needs to be replaced, the fixing bolt is unscrewed from the threaded hole 324 to remove the grinding wheel 322. Similarly, during installation, the insert block 323 is inserted into the inner wall of the mounting slot 321, and then the fixing bolt is tightened into the inner wall of the threaded hole 324.
