Description

Technical Field

[0001] This utility model relates to the field of lens barrel processing technology, and in particular to a tooling for processing optical instrument lens barrels that is easy to position. Background Technology

[0002] A telescope is an optical instrument that uses lenses, mirrors, and other optical components to observe distant objects. It works by refracting light through a lens or reflecting it with a concave mirror, causing the light to converge into an image through a small aperture. This image is then magnified by an eyepiece and seen through the lens; hence, it is also called a "telescope." During the manufacturing process of optical instrument telescopes, auxiliary positioning is required before processing.

[0003] Chinese Patent Publication No. CN222078641U discloses a machining fixture for a main lens barrel, including a base for mounting the fixture, a clamping fixture fixedly mounted at the front end of the base, and a connecting rod surrounding the outer surface of the clamping fixture. The clamping fixture and the connecting rod each have a cavity inside. A retaining rod is arranged around the inside of the clamping fixture, with opposite sides of the two retaining rods penetrating the clamping fixture and extending into the interior of the connecting rod. Adjusting bolts are provided on opposite sides of the two connecting rods. This machining fixture for the main lens barrel, through the inclusion of retaining rods, adjusting bolts, support springs, and connecting rods, allows for adaptive adjustment according to the size of the lens barrel during use, thus meeting the requirements of different lens barrel specifications and eliminating the need for users to change fixtures.

[0004] While the above technical solution allows for adjustment based on the size of the lens barrel, it requires loosening each adjusting bolt individually. After the lens barrel is placed, the user then tightens each adjusting bolt 5 to limit the position of the stop rod 4. This process of loosening and tightening each bolt is time-consuming, thus affecting the lens barrel processing efficiency. Therefore, it is necessary to provide a tooling for optical instrument lens barrel processing that facilitates positioning and solves the aforementioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tooling for machining optical instrument barrels that is easy to position.

[0006] This utility model provides a tooling for machining optical instrument barrels that facilitates positioning. It includes a base plate on which machining equipment is mounted, and further includes: a positioning component mounted on the base plate for positioning the barrel; and an adjustment component mounted on the bottom of the base plate for moving the positioning component.

[0007] Preferably, the positioning component includes a circular frame, a toothed ring rotatably connected inside the circular frame, a long gear meshing on the toothed ring, multiple long gears rotatably connected to the circular frame, racks meshing on the outside of each of the multiple long gears, and positioning heads fixedly installed at the ends of the multiple racks that are close to each other.

[0008] Preferably, the circular frame is provided with through holes evenly distributed, and the plurality of racks are all passed through and slidably connected to the through holes.

[0009] Preferably, a drive motor is installed on the outside of the circular frame, and the output end of the drive motor is fixedly connected to one of the long gears through a coupling. Support legs are symmetrically fixedly connected to the bottom of the circular frame.

[0010] Preferably, the adjusting component includes mounting plates symmetrically installed on the bottom of the base plate, and the base plate has symmetrical through slots.

[0011] Preferably, an adjusting motor is mounted on the outside of one of the mounting plates, and the output end of the adjusting motor is fixedly connected to a lead screw via a coupling, with a slider threaded onto the outside of the lead screw.

[0012] Preferably, guide rods are symmetrically installed on the top of the slider, and the two guide rods pass through the through groove and are fixedly connected to the support leg.

[0013] Preferably, limiting rods are symmetrically fixedly connected between the two mounting plates, and both limiting rods are slidably connected to the slider.

[0014] Compared with related technologies, the optical instrument barrel processing fixture provided by this utility model, which facilitates positioning, has the following beneficial effects:

[0015] This utility model is equipped with a positioning component. The motor drives the long gear to rotate, which in turn drives the gear ring to rotate, and then drives multiple long gears and racks to rotate synchronously. This makes it easy to adapt to different sizes of lens barrels without the need for individual adjustment. This not only greatly shortens the changeover time for different specifications of lens barrels, but more importantly, it ensures the concentricity of the positioning head, so that the lens barrel is always in a centered positioning state, effectively avoiding the processing eccentricity problem caused by the adjustment deviation of a single positioning head.

[0016] This utility model is equipped with an adjustment component, which can drive the positioning component to move forward or backward, thereby facilitating the adaptation to different lengths of lens barrels, improving the adaptability of the equipment and increasing the processing efficiency of lens barrels.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figures 1 to 6 This utility model provides a tooling for machining optical instrument barrels that facilitates positioning. It includes a base plate 1, which serves as the fundamental support component of the entire tooling and is made of high-strength cast iron. Cast iron possesses excellent shock absorption and structural stability, effectively absorbing vibrations generated during machining. A machining device 2 is mounted on the base plate 1. The tooling also includes a positioning component 3 mounted on the base plate 1, used for positioning the barrel. The base plate 1 provides a stable mounting platform for the machining device 2 and the positioning component 3, reducing machining errors caused by foundation sway. Finally, an adjustment component 4 is mounted at the bottom of the base plate 1, used for moving the positioning component 3.

[0027] Specifically, the positioning component 3 includes a circular frame 5, made of high-quality carbon structural steel, which significantly improves the wear resistance and deformation resistance of the component. A gear ring 6 is rotatably connected inside the circular frame 5, and long gears 7 are meshed on the gear ring 6. Multiple long gears 7 are rotatably connected to the circular frame 5, and racks 8 are meshed on the outside of each of the long gears 7. The racks 8 are made of high-strength aluminum alloy, which reduces the overall weight while ensuring structural strength, facilitating flexible sliding. The surface of the racks 8 is anodized, improving surface hardness and wear resistance. Positioning heads 9 are fixedly installed at the ends of the racks 8 that are close to each other. The part of the positioning head 9 that contacts the lens barrel is made of polyurethane soft material. This material has suitable elasticity and hardness, which can firmly fix the lens barrel while avoiding scratches or indentations on the lens barrel surface. The surface of the positioning head 9 also has evenly distributed fine anti-slip textures, which further enhance the friction between the positioning head 9 and the lens barrel, preventing displacement of the lens barrel during processing.

[0028] Meanwhile, through holes 10 are evenly provided on the circular frame 5, and multiple racks 8 are passed through and slidably connected to the through holes 10. The inner wall of the through holes 10 on the circular frame 5 is inlaid with a wear-resistant polytetrafluoroethylene bushing (not shown in the figure). The fit clearance between the bushing and the rack 8 is controlled within the range of 0.02 to 0.05 mm, which not only ensures the smooth sliding of the rack 8, but also effectively reduces the shaking during the sliding process. At the same time, the self-lubricating properties of the bushing reduce the maintenance frequency.

[0029] It should be noted that: a drive motor 11 is installed on the outside of the circular frame 5. Both the drive motor 11 and the adjustment motor 13 behind it are high-precision servo motors, which ensure the accuracy and stability of the transmission process and provide reliable power for the automated adjustment of the tooling. The output end of the drive motor 11 is fixedly connected to one of the long gears 7 through a coupling. Support legs 12 are symmetrically fixedly connected to the bottom of the circular frame 5.

[0030] In terms of positioning and adjustment, the drive motor 11 drives the gear ring 6 and multiple long gears 7 to rotate synchronously, realizing the synchronous extension and retraction of multiple positioning heads 9. There is no need to adjust the positioning components 3 one by one. This not only greatly shortens the changeover time for different specifications of lens barrels, but more importantly, it ensures the concentricity of the positioning heads 9, so that the lens barrel is always in the center positioning state. This effectively avoids the machining eccentricity problem caused by the adjustment deviation of a single positioning head 9, and significantly improves the dimensional accuracy of lens barrel machining.

[0031] In the embodiments of this utility model, please refer to Figures 1 to 6 The adjusting component 4 includes mounting plates 18 symmetrically installed on the bottom of the base plate 1, and through slots 19 symmetrically opened on the base plate 1. It should be noted that: an adjusting motor 13 is installed on the outside of one of the mounting plates 18, and the output end of the adjusting motor 13 is fixedly connected to a lead screw 14 through a coupling. The two ends of the lead screw 14 are fixed to the mounting plate 18 through bearing seats, and a slider 15 is threadedly connected to the outside of the lead screw 14.

[0032] Furthermore, guide rods 16 are symmetrically installed on the top of the slider 15. The two guide rods 16 pass through the through slot 19 and are fixedly connected to the support leg 12. The connection between the support leg 12 and the guide rod 16 is equipped with a high-precision bearing. The outer ring of the bearing is interference-fitted with the support leg 12, and the inner ring is clearance-fitted with the guide rod 16, which ensures the coaxiality of the positioning component 3 during movement and reduces the shaking caused by the connection gap.

[0033] It should be noted that: the two mounting plates 18 are symmetrically fixedly connected with limit rods 17, and both limit rods 17 are slidably connected to the slider 15. The mating parts of the limit rods 17 and the slider 15 are provided with dust covers, which can effectively prevent the debris generated during the processing from entering the sliding gap and ensure the long-term stable operation of the adjustment component 4.

[0034] In this solution, the positioning component 3 can be driven to move forward by adjusting component 4, which makes it easier to adapt to different lengths of lens barrels and improves lens barrel processing efficiency. Through the precise control of drive motor 11 and adjusting motor 13, the entire fixture realizes automated adaptation of lens barrel diameter and length, providing a reliable guarantee for efficient and precise lens barrel processing.

[0035] The working principle of the optical instrument lens barrel processing fixture that facilitates positioning provided by this utility model is as follows:

[0036] During the positioning and adjustment stage, when positioning lens barrels of different diameters is required, the drive motor 11 is started. The output shaft of the drive motor 11 drives one of the long gears 7 to rotate via a coupling. Since the long gear 7 meshes with the gear ring 6, the rotation of the long gear 7 drives the gear ring 6 to rotate synchronously within the circular frame 5. The gear ring 6 then meshes with several other long gears 7, and under the drive of the gear ring 6, all the long gears 7 rotate simultaneously. The long gears 7 and the rack 8 form a gear and rack transmission mechanism. The rotation of the long gear 7 is converted into linear motion of the rack 8 along the through hole 10 of the circular frame 5. Multiple racks 8 move simultaneously towards the center or outward under the drive of the long gears 7, thereby driving the positioning head 9 fixed at the end of the rack 8 to synchronously approach or move away from the center position, realizing the clamping and positioning of lens barrels of different diameters. The entire process ensures the concentric adjustment of the positioning head 9, ensuring that the axis of the lens barrel is consistent with the axis of the processing equipment 2.

[0037] During the position adjustment stage, the overall position of the positioning component 3 is adjusted by the adjusting component 4 for different lengths of the lens barrel. The adjusting motor 13 is started, and its output shaft drives the lead screw 14 to rotate via a coupling. Since the lead screw 14 and the slider 15 are threadedly connected, and the slider 15 cannot rotate due to the symmetrically arranged limiting rods 17, the rotational motion of the lead screw 14 is converted into the linear motion of the slider 15. The guide rod 16 at the top of the slider 15 passes through the through slot 19 on the base plate 1 and is fixedly connected to the support leg 12 of the positioning component 3. When the slider 15 moves linearly along the limiting rod 17, the guide rod 16 drives the support leg 12 and the entire positioning component 3 to move synchronously, thereby changing the position of the positioning component 3 on the base plate 1 to match the length of the lens barrel, ensuring that the processing equipment 2 can accurately act on the processing part of the lens barrel.

[0038] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0039] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
