Abstract
Description
Technical Field
[0001] This application relates to the field of inspection tool technology, and more specifically, to a device for measuring the static balance of optical components made of ceramic materials. Background Technology
[0002] In optical systems, even the slightest asymmetry or imbalance can cause deviations in the optical path, thus affecting image quality. Therefore, ensuring that optical components are in an ideal state of balance is one of the key factors in optimizing system performance. Furthermore, with the development of space optics, optical systems are becoming increasingly complex, with higher resolutions and increasingly stringent requirements for assembly precision.
[0003] Ceramic materials, with their high hardness and low coefficient of thermal expansion, are widely used in optical components. Static balance measurements of optical components typically involve determining the center of gravity of each component and ensuring that this center of gravity lies on the ideal axis of its supporting structure. Using physical suspension methods allows for a simple and intuitive observation of whether an optical component is in equilibrium under any given condition. Traditional balancing devices are mainly used for automotive wheels, grinding wheels, and cutting tools, primarily for dynamic balancing. However, these devices are expensive, inconvenient to use, and unsuitable for static balance measurements of optical components. Utility Model Content
[0004] To overcome the above deficiencies, this application provides an apparatus for measuring the static balance of optical components made of ceramic materials, which aims to improve the problems mentioned in the background art.
[0005] This application provides a device for static balance measurement of optical components made of ceramic materials, including a base plate and two support seats with V-shaped openings. A translation mechanism is provided on the base plate. One of the support seats is fixedly connected to one end of the base plate, and the other support seat is disposed on the translation mechanism. A retractable suction head is provided at the center of the V-shaped opening, and an elastic mechanism is provided inside the support seat and connected to the suction head.
[0006] In one specific implementation, the translation mechanism includes a slide rail and a slider, the slide rail being fixedly connected to the base plate, the slider being slidably connected to the slide rail, and the two sliders being fixedly connected to the corresponding support seats.
[0007] In the above implementation process, the support base is translated through two sets of slide rail systems, thereby adjusting the distance between the two support bases to accommodate optical components of different sizes.
[0008] In one specific implementation, the translation mechanism further includes a spring pin, which is mounted on the corresponding support seat, and the base plate has pin holes that are adapted to the spring pin.
[0009] In the above process, after the spacing is adjusted, the spacing is locked by inserting a spring pin into the corresponding pin hole.
[0010] In one specific implementation, the translation mechanism further includes a handle, which is fixedly connected to the corresponding support base. A lever is hinged to the handle, and the outer end of the lever is hinged to the spring pin.
[0011] In the above implementation process, the handle and lever are held together, and the lever moves closer to the handle, thereby pulling out the spring pin, which can control the translation of the support base. In this embodiment, a screw is provided on the pin, and a U-shaped groove is provided on the lever to fit into the head of the screw, so as to realize the connection between the lever and the spring pin.
[0012] In one specific implementation, the suction head includes an elastomer with an arc-shaped upper surface and suction cups evenly distributed on the upper surface. A slide rod is fixedly connected to the lower end of the elastomer, and the slide rod is slidably connected to the support base.
[0013] In the above implementation process, the elastomer is made of annular spring sheet, with a softer upper surface to fit the outer circle of the bearing and a harder lower surface for support. The bearing is held in place by a suction cup, and the slide rod has a rectangular cross section to prevent rotation. This avoids the situation where the bearing is easily shaken when directly supported on the V-shaped opening of the support seat.
[0014] In one specific implementation, the elastic mechanism includes a prismatic plate and a pulley. The prismatic plate is fixedly connected to the slide rod, and the pulley is elastically connected to the support base. The pulley rolls against the side of the prismatic plate.
[0015] In the above implementation process, the rollers press against the prism plate. The prism plate has an upper inclined surface and a lower inclined surface on its side. A groove is provided at the end of the lower inclined surface. When the roller is on the upper inclined surface, it will push the prism plate downward, causing the suction head to generate a downward pull. When the roller is on the lower inclined surface, it will push the suction head upward until the roller enters the groove, keeping the suction head in the ejected state. In this embodiment, there are two rollers that press inward from both ends of the prism plate. The rollers also have guards to prevent the rollers from slipping off the side of the prism plate.
[0016] In one specific implementation, the elastic mechanism further includes a base and a rocker arm, the base being fixedly connected to the support seat, one end of the rocker arm being hinged to the base, the pulley being rotatably connected to the other end of the rocker arm, and a tension spring being provided between the base and the rocker arm.
[0017] In the above process, the tension spring pulls the rocker arm to squeeze the prism plate, generating elastic force on the suction head and helping to position the suction head in both the ejection and suction states.
[0018] In one specific implementation, the support base has a cavity on its side to accommodate the elastic mechanism, and a cover plate is provided at the opening of the cavity.
[0019] In the above implementation process, the cover plate is fixed to the support plate with screws to cover the cavity.
[0020] Compared with the prior art, the beneficial effects of this application are: the spacing of the support base is adjusted by using a translation mechanism to adapt to optical elements of different sizes, the bearing is directly pressed down on the suction head to achieve adsorption, and the suction head is pulled by an elastic mechanism to tighten the bearing in the V-shaped opening to achieve a locking effect. When the measurement is finished, the bearing can be directly pulled out, which simplifies the operation. Attached Figure Description

Detailed Implementation
[0028] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.
[0029] Please see Figures 1-5 This application provides a device for static balance measurement of optical components made of ceramic materials, including a base plate 10 and two support seats 20 with V-shaped openings. A translation mechanism 30 is provided on the base plate 10. One support seat 20 is fixedly connected to one end of the base plate 10, and the other support seat 20 is disposed on the translation mechanism 30. A retractable suction head 40 is disposed at the center of the V-shaped opening. An elastic mechanism 50 is disposed inside the support seat 20 and connected to the suction head 40. The translation mechanism 30 is used to adjust the spacing of the support seats 20 to accommodate optical components of different sizes. The bearing is directly pressed down on the suction head 40 to achieve adsorption. At the same time, the elastic mechanism 50 pulls the suction head 40 to tighten the bearing in the V-shaped opening, achieving a locking effect. When the measurement is finished, the bearing can be directly pulled out, simplifying the operation.
[0030] Please see Figures 1-5 The translation mechanism 30 includes a slide rail 31 and a slider 32. The slide rail 31 is fixedly connected to the base plate 10, and the slider 32 is slidably connected to the slide rail 31. The two sliders 32 are fixedly connected to the corresponding support seats 20. The support seats 20 are translated through the two sets of slide rail 31 systems, thereby adjusting the distance between the two support seats 20 to accommodate optical elements of different sizes.
[0031] Please see Figures 1-5 The translation mechanism 30 also includes a spring pin 33, which is mounted on the corresponding support 20. The base plate 10 has pin holes that fit the spring pin 33. After the spacing is adjusted, the spacing is locked by inserting the spring pin 33 into the corresponding pin hole.
[0032] Please see Figures 1-5 The translation mechanism 30 also includes a handle 34, which is fixedly connected to the corresponding support base 20. A lever 35 is hinged to the handle 34, and the outer end of the lever 35 is hinged to a spring pin 33. When the handle 34 and the lever 35 are held together, the lever 35 moves closer to the handle 34, thereby pulling out the pin of the spring pin 33, which can control the translation of the support base 20. In this embodiment, a screw is provided on the pin, and a U-shaped groove is provided on the lever 35 to fit into the head of the screw, realizing the connection between the lever 35 and the spring pin 33.
[0033] Please see Figures 1-5The suction head 40 includes an elastic body 41 with an arc-shaped upper surface. Suction cups 42 are evenly distributed on the upper surface of the elastic body 41. A slide rod 43 is fixedly connected to the lower end of the elastic body 41, and the slide rod 43 is slidably connected to the support base 20. The elastic body 41 is made of annular spring sheets, with a softer upper surface to fit the outer circle of the bearing and a harder lower surface for support. The bearing is held in place by the suction cups 42. The slide rod 43 has a rectangular cross-section to prevent rotation. This avoids the situation where the bearing would easily wobble if directly supported on the V-shaped opening of the support base 20.
[0034] Please see Figures 1-5 The elastic mechanism 50 includes a prismatic plate 51 and a pulley 52. The prismatic plate 51 is fixedly connected to the slide rod 43, and the pulley 52 is elastically connected to the support base 20. The pulley 52 rolls against the side of the prismatic plate 51. The pulley 52 presses against the prismatic plate 51, which has an upper and a lower inclined surface on its side. A groove is provided at the end of the lower inclined surface. When the pulley is on the upper inclined surface, it pushes the prismatic plate 51 downward, causing the suction head 40 to generate a downward pull. When the pulley is on the lower inclined surface, it pushes the suction head 40 upward until the pulley enters the groove, keeping the suction head 40 in an extended state. In this embodiment, there are two pulleys 52, which press inward from both ends of the prismatic plate 51. The pulleys 52 also have guards to prevent the pulleys from slipping off the side of the prismatic plate 51.
[0035] Please see Figures 1-5 The elastic mechanism 50 also includes a base 53 and a rocker arm 54. The base 53 is fixedly connected to the support base 20. One end of the rocker arm 54 is hinged to the base 53, and a pulley 52 is rotatably connected to the other end of the rocker arm 54. A tension spring 55 is provided between the base 53 and the rocker arm 54. The tension spring 55 pulls the rocker arm 54 to press against the prismatic plate 51, generating elastic force on the suction head 40 and helping to position the suction head 40 in both the ejected and suction-down states.
[0036] Please see Figures 1-5 The support base 20 has a cavity on its side to accommodate the elastic mechanism 50, and a cover plate 21 is provided at the opening of the cavity. The cover plate 21 is fixed to the support plate with screws and is used to cover the cavity.
[0037] The working principle of this device for static balance measurement of optical components made of ceramic materials is as follows: When adjusting the spacing, the handle 34 and the lever 35 are held together, and the lever 35 moves closer to the handle 34, thereby pulling out the pin of the spring pin 33, which controls the translation of the support 20. After releasing the handle, the spring pin 33 is inserted into the corresponding pin hole, thereby locking the spacing. It can be operated with one hand. The suction head 40 is kept in the ejected state. The optical component is bonded to the conical hole through the trunnion. One end of the connecting rod passes through the trunnion, and the connecting rod and the trunnion are fixed by screws. The other end of the connecting rod passes through the inner hole of the bearing. The bearing is placed on the suction head 40 and pressed down. During the pressing process, the suction cup 42 fully squeezes and adheres to the bearing until the roller moves from the lower inclined surface of the prismatic plate 51 to the upper inclined surface. The prismatic plate 51 then presses against the suction head 40. A downward pulling force is generated, tightening the bearing onto the V-shaped opening of the support base 20, thus achieving a fixing effect. Then, the optical element can be rotated for static balance measurement. After the measurement is completed, the bearing is directly pulled up, and the roller rolls from the upper inclined surface to the slot on the lower inclined surface, forming a limit on the prism plate 51. At this time, the bearing can be pulled up by force to disengage from the suction head 40, and the suction head 40 is kept in the ejected state for the next measurement. In summary, the spacing of the support base 20 is adjusted by the translation mechanism 30 to accommodate optical elements of different sizes. The bearing is directly pressed down on the suction head 40 to achieve adsorption. At the same time, the elastic mechanism 50 pulls the suction head 40 to tighten the bearing onto the V-shaped opening, achieving a locking effect. When the measurement is finished, the bearing can be directly pulled out, simplifying the operation.
