A clamping fixture for the research and development of optical components

Abstract

This utility model discloses a clamping fixture for the research and development of optical components, including an upper pressure plate and a lower support plate directly below the upper pressure plate. Grooves are formed in the middle of both the upper pressure plate and the lower support plate, and support shafts are evenly arranged in the grooves. Connecting shafts are fixedly connected to the middle of the two side walls of each support shaft. The support shafts are rotatably connected to the grooves via the connecting shafts. Two rubber sleeves are fixedly connected to the outer wall of each support shaft, and a slot is formed between the two rubber sleeves. The number of support shafts in the upper pressure plate and the lower support plate is different. This utility model has the following advantages: Inserting the lens into the slot positions the edge of the lens; simultaneously, the rubber sleeves on the support shafts clamp the lens edge, ensuring stable placement. Because the support shafts are cylindrical, the contact area with the lens is small, reducing the area obstructing the lens edge and exposing most of the edge, thus ensuring the collection of research data.

Description

Technical Field

[0001] This utility model relates to the field of optical component clamping fixture technology, specifically to a clamping fixture for optical component research and development. Background Technology

[0002] Optical components are assembly parts used in optical equipment, mainly various lenses, such as lenses, prisms and mirrors. These lenses need to be kept in position during research and development to avoid affecting the research and development results due to instability.

[0003] Currently, lens clamping can obstruct the lens edges, which affects the collection of lens development data. Furthermore, current clamping devices are mostly fixed and cannot meet the requirements for collecting some lens tilt data. Therefore, this paper proposes a clamping fixture for optical component development. Utility Model Content

[0004] The technical problem this invention aims to solve is that current lens clamping methods obstruct the lens edges, which affects the collection of lens research and development data. Furthermore, current clamping devices are mostly fixed and cannot meet the requirements for collecting some lens tilt data. This invention provides a clamping fixture for optical component research and development that reduces the obstruction range of the edges, allows the lens to be rotated to change the obstructed position, and the device itself can adjust the tilt angle as needed, thereby improving the comprehensiveness of the research and development data.

[0005] The technical solution adopted by this utility model to solve the technical problem is: a clamping fixture for the research and development of optical components, including an upper pressure plate, a lower support plate provided directly below the upper pressure plate, a groove provided in the middle of both the upper pressure plate and the lower support plate, a support shaft evenly provided in the groove, a connecting shaft fixedly connected to the middle of the two side walls of the support shaft, the support shaft being rotatably connected to the groove through the connecting shaft, two rubber sleeves fixedly connected to the outer ring wall of the support shaft, and a slot provided between the two rubber sleeves, the number of support shafts in the upper pressure plate and the lower support plate are different.

[0006] As a preferred technical solution of this utility model, a rotating shaft is fixedly connected to the bottom end of the lower support plate, and a base is provided below the lower support plate. An arc-shaped groove is opened in the top side wall of the base, and the rotating shaft is rotatably connected in the arc-shaped groove.

[0007] As a preferred technical solution of this utility model, a mounting box is detachably connected to one side wall of the top of the base, and a motor is detachably connected inside the mounting box. The output end of the motor is detachably connected to one side wall of the rotating shaft.

[0008] As a preferred technical solution of this utility model, a top plate is provided above the upper pressure plate, a stud is rotatably connected in the middle of the top plate, and a connecting post is fixedly connected in the middle of the side wall opposite to the top plate of the upper pressure plate, and the stud is threaded into the connecting post.

[0009] As a preferred embodiment of this utility model, the bottom sidewalls at both ends of the top plate are fixedly connected with limiting columns, the top edge sidewalls at both ends of the upper pressure plate are fixedly connected with side plates, the side plates are sleeved on the limiting columns, the bottom end of the limiting columns is fixedly connected with a connecting plate, and the connecting plate is fixedly connected to the two sidewalls of the lower support plate.

[0010] This utility model has the following advantages: The lens is inserted into the slot to position the edge of the lens. At the same time, a rubber sleeve is fitted on the support shaft to clamp the edge of the lens and ensure the stability of the lens. Because the support shaft is cylindrical, the contact area with the lens is small, reducing the area of ​​obstruction of the lens edge and exposing most of the edge, thus ensuring the collection of research data. Rotating the lens can change the obstructed position, and because the obstruction area is small, the rotation range is small, improving the adjustment effect and the efficiency of data collection. The motor drives the rotating shaft to rotate, which in turn causes the lower support plate and upper pressure plate to rotate and tilt along the shaft. This allows the lens to be adjusted to different angles, thereby enabling the detection of the tilted lens and improving the flexibility of the application. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings.

[0014] Please refer to the following: Figure 1-3This utility model discloses a clamping fixture for the research and development of optical components, including an upper pressure plate 1 and a lower support plate 2 directly below the upper pressure plate 1. A groove 3 is provided in the middle of both the upper pressure plate 1 and the lower support plate 2. Support shafts 4 are evenly arranged in the groove 3. A connecting shaft 16 is fixedly connected to the middle of the two side walls of the support shaft 4. The support shaft 4 is rotatably connected to the groove 3 through the connecting shaft 16. Two rubber sleeves 14 are fixedly connected to the outer ring wall of the support shaft 4, and a slot 15 is provided between the two rubber sleeves 14. The number of support shafts 4 in the upper pressure plate 1 and the lower support plate 2 is different. A top plate 7 is provided above the upper pressure plate 1. A stud 8 is rotatably inserted through the middle of the top plate 7. A connecting post 9 is fixedly connected in the middle of the side wall opposite to the top plate 7 of the upper pressure plate 1. The stud 8 is threaded into the connecting post 9. A limiting post 6 is fixedly connected to the bottom side wall of both ends of the top plate 7. A side plate 5 is fixedly connected to the side wall of the top edge of both ends of the upper pressure plate 1. The side plate 5 is sleeved on the limiting post 6. A mating plate 10 is fixedly connected to the bottom end of the limiting post 6. The mating plate 10 is fixedly connected to the two side walls of the lower support plate 2.

[0015] The technical effect of this solution is as follows: the lens to be tested is placed on the lower support shaft 4, and the edge of the lens is inserted into the slot 15. Then, the stud 8 is rotated to drive the connecting column 9 and the upper pressure plate 1 to descend through the thread relationship, thereby clamping and positioning the lens. After the lens is clamped and positioned, research and development testing is carried out. When necessary, the lens can be rotated. Because the support shaft 4 can rotate, the smoothness of the lens rotation can be ensured, thereby adjusting the edge of the lens that is blocked and ensuring the comprehensiveness of data collection. Similarly, the rubber sleeve 14 connected to the support shaft 4 can ensure the stability of the lens and avoid wear on the lens during rotation.

[0016] A rotating shaft 11 is fixedly connected to the bottom end of the lower support plate 2. A base 12 is provided below the lower support plate 2. An arc-shaped groove is opened in the top side wall of the base 12. The rotating shaft 11 is rotatably connected in the arc-shaped groove. A mounting box 13 is detachably connected to one side wall of the top of the base 12. A motor 17 is detachably connected in the mounting box 13. The output end of the motor 17 is detachably connected to one side wall of the rotating shaft 11.

[0017] The technical effect of this solution is as follows: when needed, the motor 17 is started to drive the rotating shaft 11 to rotate. As the rotating shaft 11 rotates, it can drive the lower support plate 2 and the upper pressure plate 1 to move synchronously. This can adjust the tilt angle of the lower support plate 2 and the upper pressure plate 1, and also adjust the clamped lens synchronously. In this way, the lens can be adjusted to different angles to collect research and development data under the tilted state of the lens.

[0018] Specifically, when using this invention, the bottom of the lens is inserted into the corresponding slot 15, and then the stud 8 is rotated. Through the threaded connection, the upper pressure plate 1 is driven to descend along the limiting post 6, thereby locking the slot 15 in the middle of the upper support shaft 4 at the edge of the lens, thus ensuring that the lens is clamped and positioned. Then, the lens is used for research and development testing. When necessary, the lens is rotated. As the lens rotates, the position connected to the support shaft 4 is changed, thereby exposing the originally blocked position and ensuring the collection of data from the edge of the lens. The motor 17 is started to drive the rotating shaft 11 to rotate, which drives the lower support plate 2, the upper pressure plate 1, and the clamped lens to rotate and adjust synchronously, thereby adjusting the lens to a suitable tilt angle. In this way, research and development data can be collected from the lens in the tilted state.

[0019] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0020] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
