Description

Technical Field

[0001] This invention relates to the field of optical lens adjustment frame technology, and more particularly to an air-bearing adjustment frame for large-diameter optical lenses. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent the glass block from developing internal stress. After cooling, the glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. Qualified glass blocks are then heated and forged to form optical lens blanks. However, existing optical elements or optical assemblies are large in size and weigh more than 1,000 kilograms, making them difficult to move. Their reflectors are also difficult to disassemble and replace due to long-term use, and their protection is poor and they are easily damaged.

[0003] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large-aperture optical lens air-float adjustment frame includes a base plate, casters, and optical components. The casters are installed at the bottom end of the base plate. Vertical frames are symmetrically installed at the top of the base plate. A positioning pressure plate is provided at the top of the vertical frames.

An anti-collision frame is movably provided at the top of the base plate. The optical components are installed in the inner end of the anti-collision frame. The outer end of the anti-collision frame is movably engaged with the protective claws and the positioning pressure plate. The protective claws and the positioning pressure plate are both fixedly provided on locking protrusions. The locking protrusions are embedded in the corresponding grooves of the anti-collision frame. A pull rod is rotatably connected to the bottom surface of the positioning pressure plate. The end of the pull rod away from the positioning pressure plate slides through the top of the vertical frame and is fixedly connected to a pull buckle assembly.

[0007] The bottom end of the base plate is equipped with air-float light blocks and air-float drive components. The air-float light blocks are arranged in a matrix, and there are multiple air-float drive components and multiple air-float light blocks, with one-to-one correspondence between the air-float drive components and the air-float light blocks. The air-float drive components are connected through air-float tubes. The air-float drive components include air-float cylinder liners, air-float return spring sleeves, air-float sliders, and air-float slide rods. The air-float cylinder liners are installed at the bottom of the base plate, and the air-float return spring sleeves and air-float sliders are both located inside the air-float cylinder liners. The outer end of the slider abuts against the inner wall of the air float cylinder sleeve, and the bottom end of the air float slider is fixedly connected to the air float slide rod. The end of the air float slide rod away from the air float slider slides through the bottom wall of the air float cylinder sleeve to its outside and is fixedly connected to the air float block. The air float return sleeve is sleeved on the outer end of the air float slide rod, and the two ends of the air float return sleeve abut against the bottom wall of the air float slider and the air float cylinder sleeve, respectively. The top wall of the air float cylinder sleeve is provided with an air inlet hole, which is connected to the air float tube.

[0008] Furthermore, the pull buckle assembly consists of a U-shaped connector, a U-shaped link, a protruding connector, and a handle. The U-shaped connector is rotatably connected to the U-shaped link, and the U-shaped connector is fixedly connected to the pull rod. The end of the U-shaped link away from the U-shaped connector is hinged to the handle. The protruding connector is fixedly mounted on the vertical frame and is hinged to the handle.

[0009] Furthermore, the base plate is composed of a first granite slab, a second granite slab, and a third granite slab, which are arranged sequentially from top to bottom. The air-bearing drive assembly is installed inside the third granite slab. The vertical frame is installed on the first granite slab. A horizontal structure for driving the second granite slab to move horizontally is installed at the top of the first granite slab, and a pitching structure for driving the first granite slab to deflect is installed on the second granite slab.

[0010] Furthermore, the anti-collision frame includes an upper frame, a lower frame, a left frame, a right frame, and corner reinforcements. Each of the upper frame, lower frame, left frame, and right frame has screw holes. Each of the opposite surfaces of the upper frame, lower frame, left frame, and right frame has a polyoxymethylene clip and a second screw. The second screw is threadedly connected to the upper frame, lower frame, left frame, and right frame, respectively. Multiple corner reinforcements are provided, located at the corners of the anti-collision frame, and are fixedly connected to the upper frame, lower frame, left frame, and right frame by bolts. The polyoxymethylene clip has first rubber pads on both sides, fixedly located on the opposite surfaces of the upper frame, lower frame, left frame, and right frame. The top surface of the lower frame has a stress-bearing elastic pad, which is located on both sides of the polyoxymethylene clip.

[0011] Furthermore, both the left and right side frames are provided with positioning pins and positioning holes. The positioning pins are located on the bottom opposite surfaces of the left and right side frames, and the positioning holes are located on the top surfaces of the left and right side frames.

The two ends of the lower frame are provided with positioning holes that are adapted to the positioning pins of the left and right side frames, and the positioning pins are located in the positioning holes.

[0012] Furthermore, the left and right side frames are respectively provided with a left shaft and a right shaft. The left and right shafts are respectively fixedly connected to bearing seats. Several first screws are provided at the bearing seats. The first screws are threaded through the bearing seats and are threadedly connected to the left and right side frames respectively. The left and right shafts are driven by a flipping mechanism. The flipping mechanism consists of a U-shaped support frame, a servo motor and a receiving bushing. Two receiving bushings are symmetrically provided, and the receiving shaft is rotatably located at the top of the U-shaped support frame. The receiving bushings are respectively engaged with the left and right shafts. The servo motor is fixedly located at the top of the U-shaped support frame, and one of the receiving bushings is fixedly connected to the output shaft of the servo motor.

[0013] Furthermore, the upper and lower frames are respectively threaded with slow-descent adjustment screws, and there are four slow-descent adjustment screws arranged in a U-shape.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] 1. This invention utilizes three granite slabs, casters, a horizontal structure, a tilting structure, a vertical frame, a positioning pressure plate, a pull-button assembly, and protective claws to lock and disassemble the optical components within the anti-collision frame. The anti-collision frame protects the optical components, reducing stress during parallel and tilting movements, making the optical components safer during movement and tilting. This not only solves the problem of poor protection for optical elements in traditional structures but also addresses the inconvenience of disassembling and replacing the anti-collision frame. Furthermore, the inclusion of air-floating light blocks, air-floating tubes, air-floating cylinder liners, air-floating return sleeves, air-floating sliders, and air-floating slide rods facilitates raising and pushing the invention, resolving the problem of the heavy optical components being difficult to move.

[0016] 2. This invention enables easy replacement of optical components by using a decomposable and combinable anti-collision frame, reducing material consumption and making the anti-collision frame reusable. Furthermore, the use of a shaft in conjunction with a flipping mechanism further enhances the applicability of the optical components, making their application range wider.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1:

[0030] like Figures 1-6As shown, a large-diameter optical lens air-bearing adjustment frame includes a base plate 1, casters 2, and an optical component 10. The casters 2 are installed at the bottom end of the base plate 1. Vertical frames 5 are symmetrically installed at the top of the base plate 1. The top of the vertical frames 5 is provided with a positioning pressure plate 6. Protective claws 8 are provided on both sides of the two vertical frames 5. One side of the protective claws 8 is hinged to the vertical frames 5. An anti-collision frame 9 is movably installed at the top of the base plate 1. The optical component 10 is installed inside the anti-collision frame 9. The outer end of the anti-collision frame 9 is movably engaged with the protective claws 8 and the positioning pressure plate 6. The protective claws 8 and the positioning pressure plate 6 are both fixedly provided with locking protrusions, which are embedded in the corresponding anti-collision frames 9. Inside the groove, a pull rod 11 is rotatably connected to the bottom surface of the positioning plate 6. The end of the pull rod 11 away from the positioning plate 6 slides through the top of the vertical frame 5 and is fixedly connected to a buckle assembly 7. The buckle assembly 7 consists of a U-shaped connector 701, a U-shaped connecting rod 702, a protruding connector 703, and a handle 704. The U-shaped connector 701 is rotatably connected to the U-shaped connecting rod 702, and the U-shaped connector 701 is fixedly connected to the pull rod 11. The end of the U-shaped connecting rod 702 away from the U-shaped connector 701 is hinged to the handle 704. The protruding connector 703 is fixedly mounted on the vertical frame 5 and is hinged to the handle 704.

[0031] When installing the anti-collision frame 9, insert the bottom protrusion of the frame into the corresponding groove, then pull the handle 704 upwards. The handle 704 rotates in an arc around the hinge point with the protruding connector 703, causing the U-shaped connecting rod 702 hinged to the handle 704 to move upwards. After the U-shaped connecting rod 702 moves upwards, it pushes the protruding connector 703 hinged to it to move upwards. After the protruding connector 703 moves upwards, it pushes the pull rod 11 fixed to it to move upwards. After the pull rod 11 moves upwards, it drives the positioning pressure plate 6, which rotates with it, to move upwards. The positioning pressure plate 6 moves upwards with a gap between it and the top surface of the vertical frame 5. Then, rotate the positioning pressure plate 6 so that the locking protrusion of the positioning pressure plate 6 is aligned with the groove at the top of the anti-collision frame 9. Then, pull the handle in the opposite direction. Handle 704, after being driven by the component, is parallel to the vertical frame 5, and the locking protrusion is embedded in the groove at the top of the anti-collision frame 9. Then, the protective claw 8 is pushed to rotate, and its locking protrusion is embedded in the groove on the side of the protective frame. The groove is provided with an elastic piece, which increases friction and stress, making the pull-button assembly 7 more secure, thus making it more stable when moving the optical component 10. When it is necessary to disassemble the component, the handle 704 is pushed upward again, and then, through the above-mentioned component, the locking protrusion is disengaged from the groove at the top of the protective frame. Then, the protective claw 8 is pushed to rotate, and its locking protrusion is disengaged from the groove on the side of the protective frame. The anti-collision frame 9 can be pulled upward to disassemble and replace the optical component 10.

[0032] At the bottom end of the base plate 1, air-float light blocks 12 and air-float drive components are installed. The air-float light blocks 12 are arranged in a matrix. There are multiple air-float drive components and multiple air-float light blocks 12, and each air-float drive component corresponds to one air-float light block 12. The air-float drive component is connected to an air-float tube 13. The air-float drive component includes an air-float cylinder liner 14, an air-float return spring sleeve 15, an air-float slider 16, and an air-float slide rod 17. The air-float cylinder liner 14 is installed at the bottom of the base plate 1. The air-float return spring sleeve 15 and the air-float slider 16 are both located inside the air-float cylinder liner 14. The outer end of 16 abuts against the inner wall of the air float cylinder liner 14, and the bottom end of the air float slider 16 is fixedly connected to the air float slide rod 17. The end of the air float slide rod 17 away from the air float slider 16 slides through the bottom wall of the air float cylinder liner 14 to extend to its outside and is fixedly connected to the air float light block 12. The air float return sleeve 15 is sleeved on the outer end of the air float slide rod 17, and the two ends of the air float return sleeve 15 abut against the bottom wall of the air float slider 16 and the air float cylinder liner 14 respectively. The top wall of the air float cylinder liner 14 is provided with an air inlet hole, which is connected to the air float tube 13.

[0033] An external air compressor connected to the air flotation tube 13 introduces gas into the air flotation drive assembly. The movement of the air flotation drive assembly components is as follows: gas enters the air flotation cylinder sleeve 14 through the air inlet, and then the gas compresses the air flotation slider 16, causing it to slide along the inner wall of the air flotation cylinder sleeve 14. After sliding along the inner wall of the air flotation cylinder sleeve 14, the air flotation slider 16 drives the air flotation slide rod 17 fixed to it to slide outwards from the air flotation cylinder sleeve 14. At the same time, the air flotation slider 16 compresses the air flotation return sleeve 15. The reverse force of the air flotation return sleeve 15 provides a certain damping to the air flotation slider 16, making its sliding more stable. Then, the air flotation slide rod 17 moves the air flotation light block 12 fixed to it downwards in a relatively stable manner. This ensures that each air flotation light block 12 rises by an equal amount, equidistantly expanding the gap between the equipment and the ground, and avoiding unnecessary damage to the optical components inside the anti-collision frame 9. The tilt is controlled by an air flotation drive assembly, and each air flotation drive assembly can bear a weight of 500 kg, with a total buoyancy of 4.5 tons. An air pressure valve and pressure gauge are also installed at the air flotation pipe 13 that controls the air flotation drive assembly. The air source is adjusted by the pressure regulating valve. According to the weight of the equipment, the operator can freely adjust and control the air pressure so that it can float easily. An air source switch is also installed. When the air source switch button is pressed, the air source quickly squeezes the air flotation block 12 out and generates a counterforce with the optical platform surface, which floats the two-dimensional adjustment frame of the large-diameter reflector. The frame can be easily pushed. When the frame is pushed to the predetermined area, the button on the air source switch handle 704 is released to cut off the air source to the air flotation drive assembly, so that the equipment stops smoothly in the predetermined area. In case of air flotation failure, the hanging wheel 2 can continue to move and work on the optical platform to ensure the normal movement of the equipment.

[0034] The base plate 1 is composed of a first granite slab, a second granite slab, and a third granite slab, arranged sequentially from top to bottom. The air-bearing drive assembly is installed inside the third granite slab, and the vertical frame 5 is installed on the first granite slab. A horizontal structure 3 for driving the second granite slab to move horizontally is installed at the top of the first granite slab, and a pitch structure 4 for driving the first granite slab to deflect is installed on the second granite slab. Granite has a low coefficient of thermal expansion. The horizontal structure 3 is used to drive the second granite slab to deflect horizontally, thereby causing the first granite slab to rotate horizontally and controlling the optical component 10 to deflect horizontally at a fixed angle. The pitch structure 4 is used to drive the first granite slab to pitch, thereby causing the optical component 10 to deflect vertically at a fixed angle. During this process, the protective claw 8 and the positioning pressure plate 6 protect it.

[0035] Example 2:

[0036] like Figures 7-9 As shown, in the above process, the anti-collision frame 9 protects the optical component 10 from easy damage. The anti-collision frame 9 is detachable for easy storage and replacement. During long-term use, the optical component 10 is prone to screen distortion and other issues, rendering it unusable. Replacing the entire component would be too wasteful of the anti-collision frame 9, resulting in further waste of resources.

[0037] A large-aperture optical lens air-float adjustment bracket, the anti-collision frame 9 includes an upper frame 901, a lower frame 902, a left frame 903, a right frame 904, and corner reinforcements 908. The upper frame 901, lower frame 902, left frame 903, and right frame 904 are all provided with screw holes 9014. The upper frame 901, lower frame 902, left frame 903, and right frame 904 form a U-shape and are fixed by bolts. On opposite sides of the upper frame 901, lower frame 902, left frame 903, and right frame 904, there are polyoxymethylene clips 9013 and second screws 9017. The second screws 9017 are used to fix the polyoxymethylene clips 9013. The polyoxymethylene clips 9013 are adapted to the grooves of the optical components 10, thereby reducing stress and protecting the optical components. Part 10, the second screw 9017 is threadedly connected to the upper frame 901, lower frame 902, left frame 903 and right frame 904 respectively, the corner reinforcement 908 is provided in multiple locations, and the corner reinforcement 908 is provided at the corner of the anti-collision frame 9, and the corner reinforcement 908 is fixedly connected to the upper frame 901, lower frame 902, left frame 903 and right frame 904 respectively by bolts, the polyoxymethylene strip 9013 is provided with first rubber pads 9016 on both sides, the first rubber pads 9016 are fixedly provided on the opposite sides of the upper frame 901, lower frame 902, left frame 903 and right frame 904 respectively, and the top surface of the lower frame 902 is provided with a force-bearing elastic pad 9012, the force-bearing elastic pad 9012 is provided on both sides of the polyoxymethylene strip 9013;

[0038] The left frame 903 and the right frame 904 are both provided with positioning pins 909 and positioning holes 9015. The positioning pins 909 are located on the bottom opposite surfaces of the left frame 903 and the right frame 904, and the positioning holes 9015 are located on the top of the left frame 903 and the right frame 904. The bottom surface of the upper frame 901 is provided with positioning pins 909 on both sides to match the positioning holes 9015 of the left frame 903 and the right frame 904. The two ends of the lower frame 902 are provided with positioning holes 9015 to match the positioning pins 909 of the left frame 903 and the right frame 904. The positioning pins 909 are located in the positioning holes 9015. The upper frame 901 and the lower frame 902 are respectively threaded with slow-descent adjustment screws 907. There are four slow-descent adjustment screws 907 arranged in a U-shape. The slow-descent adjustment screws 907 are used to ensure that the bottom of the mirror is safe and free from scratches and damage when the hydraulic forklift is lifted.

[0039] During installation, insert the four slow-descent adjusting screws 907 into the corresponding screw holes 9014 of the upper frame 901 and lower frame 902, respectively. Then, ensure one end of the slow-descent adjusting screw 907 passes through the granite slab. Place the second rubber pad 9018 on the top surface of the granite slab. After adjusting the end faces of the screws 907 to be parallel, insert the positioning pins 909 of the left frame 903 and right frame 904 into the corresponding positioning holes 9015 of the lower frame 902. Then, install the corner reinforcement parts 908 at the two corners at the bottom, install the bolts, and then place it horizontally on the granite base plate. 1. After inserting the optical component 10 from one side, the upper frame 901 is pressed towards the top of the left frame 903 and the right frame 904. Then, bolts are screwed into the upper frame 901, lower frame 902, left frame 903 and right frame 904, and corner reinforcement 908 is installed at the two corners at the top. Then, the bolts are tightened to secure the components and the polyoxymethylene clip 9013 is inserted into the corresponding groove of the optical component 10. The first rubber pad 9016 and the force-bearing elastic pad 9012 increase the friction with the optical component 10 and also play a buffering role.

[0040] When disassembling, place the anti-collision frame 9 horizontally on the granite slab, then rotate the bolt at the upper frame 901, and remove the bolt at the upper frame 901, the corner reinforcement 908, and the upper frame 901 in sequence. Then, slightly rotate the bolts at other locations to loosen the fastening of the optical component 10, and then pull out the optical component 10. Since there is a certain gap between the slow-descent adjusting screw 907 and the granite slab, it is easier to pull out. Thus, while protecting the optical component 10, it is also convenient to pull out and replace the optical component 10.

[0041] Example 3:

[0042] like Figure 7 , Figure 8 and Figure 10As shown, in Embodiment 1, the optical component 10 cannot be vertically flipped over a large range, resulting in a small range and limited applicability.

[0043] Left frame 903 and right frame 904 have left shaft 905 and right shaft 906 respectively on their opposite sides. Bearing seats 9010 are fixedly connected to left shaft 905 and right shaft 906. Several first screws 9011 are provided at the bearing seats 9010, with threads penetrating the bearing seats 9010. The first screws 9011 are also threadedly connected to left frame 903 and right frame 904 respectively. A flipping mechanism is drivenly connected to left shaft 905 and right shaft 906. The flipping mechanism consists of a U-shaped support frame 9019, a servo motor 9020, and a receiving bushing 9021. Two receiving bushings 9021 are symmetrically arranged, and the receiving shaft is rotatably mounted on the U-shaped support frame 9019. At the top of the U-shaped support frame 9019, the receiving bushing 9021 is respectively engaged with the left shaft 905 and the right shaft 906. The servo motor 9020 is fixedly mounted on the top of the U-shaped support frame 9019. One of the receiving bushings 9021 is fixedly connected to the output shaft of the servo motor 9020. When the servo motor 9020 is started, it drives the receiving bushing 9021 fixed to its output shaft to rotate. After the receiving bushing 9021 rotates, it drives the left shaft 905 or the right shaft 906 fixed to it to rotate. After the shaft rotates, it drives the bearing seat 9010 fixed to it to deflect, thereby causing the anti-collision frame 9 to deflect and adjust the vertical flip angle of the anti-collision frame 9, thus making the application scope of the present invention wider.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
