Description

Adjusting frame structure and optical system applying same
Technical Field

Background
The optical adjusting frame is widely applied to an optical system and is used for precisely fine-adjusting the position and the angle of an optical component.
In the conventional optical adjusting rack structure, referring to fig. 21 to 23, the adjusting screw 100 and the adjusting rack 200 are generally integrated, and for a multi-dimensional adjusting system, such as a three-dimensional adjusting system, a second dimension is established on a first dimension basis, and a third dimension is established on a second dimension basis. When the first dimension is adjusted, the base of the adjusting frame 200 is directly connected with the optical platform, so that the structure is stable, but when the upper dimension is adjusted, especially the third dimension, the adjusting screw 100 is rotated to apply a lateral push-pull force and a lateral rotating force to the adjusting frame 200. In addition, various bearings are generally used to make the adjusting bracket 200, and the rigidity of the bearings is weak, which may cause instability of the entire adjusting system during adjustment. Especially in some high precision adjustment applications, there is a significant amount of trouble with the overall adjustment system.
In addition, as described above, since the adjusting screw 100 is generally used to push the bearing to move to perform the adjustment, if the adjusting screw 100 is used in a flat plane, the rotation of the adjusting screw 100 generates a rotation force in the same direction on the adjusting bracket 200, reducing the stability of the entire adjusting system. Spherical contact is currently generally adopted between the adjusting screw 100 and the adjusting bracket 200 to reduce the influence of the rotation of the adjusting screw 100 on the adjusting bracket. However, due to the spherical contact, the rigidity of the metal is poor, and after a certain period of use, pits 201 are often formed on the contact surface of the adjusting bracket 200. Meanwhile, since the spherical top end of the adjusting screw 100 and the rotating shaft are difficult to be concentric, a pit 201 with a relatively large area is easily formed on the adjusting frame 200, and the existence of the pit 201 can have a large influence on the adjusting accuracy, such as increasing the rotating resistance and reducing the linearity, and the non-concentricity of the pit 201 can generate a side thrust to the bearing, reducing the service life of the bearing, and the like.

Example 1
Referring to fig. 1 to 3, an adjusting bracket structure is mainly used for being mounted on an optical platform to form an optical system with the optical platform, so that the positions of optical components mounted on the adjusting bracket structure can be adjusted.
The adjusting frame structure comprises an adjusting frame 1 and at least two adjusting structures, wherein the adjusting frame 1 is arranged on a base 5, and the base 5 can be arranged on an external optical platform, so that the adjusting frame structure and the optical platform form an optical system. In this embodiment, the adjustment structure has three, realizing adjustment in three dimensions. Each adjusting structure comprises a first adjusting screw as a coarse adjusting screw, that is, the adjusting frame structure of the present embodiment includes a first dimension adjusting screw 21, a second dimension adjusting screw 22 and a third dimension adjusting screw 23, and correspondingly, the adjusting frame 1 includes a first frame 11, a second frame 12 and a third frame 13, where correspondingly refers to the number and the position. Wherein, the first frame 11 is movably disposed on the base 5, the second frame 12 is movably disposed on the first frame 11, and the third frame 13 is movably disposed on the second frame 12. The first frame 11 can move in a first direction X relative to the base 5 to realize adjustment of a first dimension, the second frame 12 can move in a second direction Y relative to the first frame 11 to realize adjustment of a second dimension, the third frame 13 can move in a third direction Z relative to the second frame 12 to realize adjustment of a third dimension, and the first direction X, the second direction Y and the third direction Z are perpendicular to each other. Guide mechanisms in sliding fit may be provided between the first frame and the base 5, between the second frame 12 and the first frame 11, and between the third frame 13 and the second frame 12, respectively, to define movement paths of the first frame 11, the second frame 12, and the third frame 13. As shown in fig. 1, the first direction X is a left-right direction, the second direction Y is a front-rear direction, and the third direction Z is an up-down direction. The first dimension adjusting screw 21 corresponds to the first frame 11 (dimension one), the second dimension adjusting screw 22 corresponds to the second frame 12 (dimension two), and the third dimension adjusting screw 23 corresponds to the third frame 13 (dimension three).
The adjusting frame structure further comprises a bracket for setting the adjusting structure, in this embodiment comprising a first bracket 31, a second bracket 32 and a third bracket 33, each of which is fixedly arranged on the base 5 independently. Alternatively, two brackets or three brackets may be made as an integral bracket. The first dimension adjusting screw 21 passes through the first bracket 31 and is in threaded connection with the first bracket, and the top end of the first dimension adjusting screw 21 is in contact with the surface of the first frame 11, so that the first frame 11 can be pushed to move in the first direction X, and in one direction in the first direction X, the reverse movement is realized by the restoring force of an elastic member such as a tension spring 311 (as shown in fig. 3, which is respectively connected with the first frame 11 and the base 5, and the structure of each dimension is the same) in the first frame 11, and the restoring manner is the same as that of the prior art. The second dimension adjusting screw 22 passes through the second bracket 32 and is in threaded connection with the second bracket, and the top end of the second dimension adjusting screw 22 is in contact with the surface of the second frame 12, so that the second frame 12 can be pushed to move in the second direction Y, and to move in one direction of the first direction Y, and the reverse movement is realized by the restoring force of an elastic member such as a tension spring 311 (respectively connecting the second frame 12 and the base 5) in the second frame 12, and the restoring manner is the same as that of the prior art. The third dimension adjusting screw 23 passes through the third bracket 33 and is in threaded connection with the third bracket, and the top end of the third dimension adjusting screw 23 is in contact with the surface of the third bracket 13, so that the third bracket 13 can be pushed to move in the third direction Z, and the third bracket 13 can be moved in one direction in the third direction Z, and the reverse movement is realized by the restoring force of an elastic piece in the third bracket 13, such as a tension spring 311 (respectively connected to the second bracket 12 and the third bracket 13), and the restoring mode is the same as that of the prior art.
Thereby realizing that the adjusting structures of each dimension are independent of each other. When manual adjustment is carried out or motor driving is adopted, the shake of hands and motors does not generate lateral push-pull force on the whole adjusting frame 1, and the only influence is the thrust to the corresponding frame body when each adjusting screw rod is rotated. This structure enables isolation of non-tuned dimensional judder to a large extent.
Because the independent external of each adjusting structure is adopted, when the first dimension is adjusted, the surface contact mode of the first dimension adjusting screw rod 21 and the first frame body 11 is a point and a point, and when the second dimension is adjusted, the surface contact mode of the second dimension adjusting screw rod 22 and the second frame body 12 is a point and a line, because the contact position of the second dimension adjusting screw rod 22 and the second frame body 12 of the second dimension is driven to slide when the first dimension is adjusted, the contact mode of the point and the line is formed, and the length of the line is the adjustment range of the first dimension; when the third dimension is adjusted, the adjustment of the first dimension and the second dimension causes the contact between the third dimension adjusting screw 13 of the third dimension and the third frame 33, and the dimension of the surface is the adjustment range of the first dimension and the second dimension.
Example two
As mentioned above, since each first adjusting screw often adopts a spherical surface to contact with the corresponding frame surface of the adjusting frame 1, a pit is formed on the corresponding frame surface of the adjusting frame 1, which reduces the service life of the whole adjusting frame structure. To solve this problem, an alternative solution is to reduce the force between each adjusting screw and the corresponding frame surface of the adjusting frame 1 by reducing the tension of the tension springs, thereby reducing the problem of the pits. However, the reduction of the tension spring also causes the reduction of the structural load of the adjusting frame or the reduction of the stability. Particularly when each first adjusting screw is arranged externally, the pit problem of the contact point is more remarkable because the second dimension and the third dimension form point-to-line contact and point-to-surface contact.
For this reason, in the present embodiment, referring to fig. 3, on the basis of the first embodiment, a first magnet 24 is provided on each first adjusting screw, a second magnet 14 is provided in the corresponding frame of each first adjusting screw, and the first magnet 24 and the second magnet 14 are magnetically exclusive, thereby reducing the acting force between each first adjusting screw and the adjusting frame 1 and reducing wear.
In FIG. 4, F 1 : the tension of the tension spring 311 (the tension of the spring can also be used); f (F) 2 : repulsive force between the two magnets; f (F) 3 : the force of each adjusting screw acting on the corresponding frame surface of the adjusting frame 1 is satisfied by F 3 ＝F 1 -F 2 。
Example III
Referring to fig. 5, in the present embodiment, the difference from the second embodiment is that each first magnet 24 'is disposed on the base 5 and located in each frame, and the first magnet 24' and the second magnet 14 are magnetically attracted, so that the pressure between a portion of each first adjusting screw and the corresponding frame surface of the adjusting frame can be offset.
In FIG. 5, F 1 : the tension of the tension spring 311 (the tension of the spring can also be used); f (F) 2 : suction between the two magnets; f (F) 3 : the force of each first adjusting screw acting on the corresponding frame surface of the adjusting frame 1 is satisfied by F 3 ＝F 1 -F 2 。
Example IV
Referring to fig. 6 to 9, in the present embodiment, on the basis of the first embodiment, the adjustment structure of each dimension is further comprised of a second adjustment screw 25, the first adjustment screw is used as a coarse adjustment screw, and the first adjustment screw passes through only the corresponding bracket without producing a threaded connection.
A rotating plate 34 is also rotatably arranged on each bracket, and each rotating plate 34 is positioned on one side of each bracket close to the corresponding bracket body of the adjusting bracket 1. The rotation axis of each swivel plate 34 is perpendicular to the adjustment direction of the respective dimension such that each swivel plate 34 is rotatably close to or remote from the respective frame surface of the adjustment frame 1. As shown in fig. 6, the rotation axes of the rotation plates 34 on the first and second brackets 31 and 32 are each along the third direction Z, and the rotation axis of the rotation plate 34 on the third bracket 33 is along the first direction X. Each first adjusting screw also passes through the rotating plate 34 and is respectively screwed with the corresponding rotating plate 34. Thus, when the first adjusting screw is rotated, the tip end thereof pushes the corresponding frame surface of the adjusting frame 1, thereby performing rough adjustment, and simultaneously rotating the rotating plate 34 in a direction approaching the corresponding bracket.
The rotary plate 34, the second adjusting screw 25 and the corresponding support form a lever. Each second adjusting screw 25 serves as a fine adjusting screw, penetrates through the corresponding bracket and is in threaded connection with the corresponding bracket, and the top end of the second adjusting screw 25 abuts against the side surface of the rotating plate 34 facing the corresponding bracket, so that the rotating plate 34 can be pushed to rotate relative to the corresponding bracket.
Through the design, the lever principle can be utilized, when fine adjustment is needed, the second adjusting screw rod 25 acts on the lever and can push the rotating plate 34 to rotate relative to the corresponding bracket, and the corresponding first adjusting screw rod is driven to gradually push the corresponding frame body of the adjusting frame 1, so that the adjusting precision is improved. Meanwhile, the rotation force of the second adjusting screw 25 and other forces in the non-acting direction can be isolated through the lever, and the whole adjusting frame structure is not influenced.
Example five
Referring to fig. 10 to 13, in the present embodiment, the difference from the first embodiment described above is that the adjustment structure of each dimension further includes a second adjustment screw 25', the first adjustment screw being a coarse adjustment screw. The adjustment structure of each dimension further comprises a wedge 26, the second adjustment screw 25' acting as a fine adjustment screw for adjusting the movement of the wedge 26. Wedge-shaped piece 26 means that the thickness of the piece gradually decreases in one direction, formed by one of the surfaces being beveled.
Each wedge-shaped piece 26 is arranged between the corresponding first adjusting screw and the surface of the frame body of the adjusting frame 1, the surface of each frame body of the adjusting frame 1 is also provided with a push rod 15, the push rods 15 and the corresponding first adjusting screws are respectively abutted against two opposite sides of the wedge-shaped piece 26, and one side of the push rod 15 abutted against is the inclined plane side of the wedge-shaped piece 26. When each first adjusting screw pushes the corresponding wedge-shaped piece 26 to the corresponding frame body surface of the adjusting frame 1, the wedge-shaped piece 26 pushes the corresponding frame body of the adjusting frame 1 through the ejector rod 15, so that coarse adjustment is performed.
The second adjusting screw 25' is used for driving the wedge-shaped piece 26 to move linearly, and the moving direction of the wedge-shaped piece 26 is perpendicular to the adjusting direction of the corresponding dimension. As shown in fig. 10, the moving directions of the wedge-shaped pieces 26 on the first bracket 31 and the second bracket 32 are both along the third direction Z, and the moving direction of the wedge-shaped piece 26 on the third bracket 33 is along the first direction X. The movement of the wedge-shaped piece 26 can change the distance between the position corresponding to the top end of the ejector rod 15 on the inclined surface of the wedge-shaped piece 26 and the surface of the corresponding frame body, so that the distance is gradually reduced in the movement process of the wedge-shaped piece 26 by controlling the movement direction of the wedge-shaped piece 26, the ejector rod 15 is pushed to move in the direction away from the first adjusting screw, and the ejector rod 15 is further pushed to gradually push the corresponding frame body, so that fine adjustment is performed.
To facilitate the movement of the wedge 26 by the second adjusting screws 25', each second adjusting screw 25' passes through the respective bracket and is threaded between the two. A fixed seat 35 is further arranged on each support, the top end of each second adjusting screw rod 25 'is abutted against a sliding block 36, and the sliding blocks 36 are arranged between the second adjusting screw rods 25' and the fixed seat 35. The sliding block 36 is fixed with the wedge-shaped piece 26, a guide rod 37 is arranged on each fixed seat 35, the sliding block 36 is slidably connected with the guide rod 37, an elastic piece 38 is arranged on the guide rod 37, and two ends of the elastic piece 38 are respectively abutted with the sliding block 36 and the fixed seats 35, so that the sliding block 36 keeps a trend of moving towards the direction of the second adjusting screw 25'.
In the adjusting structure in the present embodiment, the torsion of the first adjusting screw rotation does not affect the adjusting bracket 1, but is isolated by the wedge 26.

Referring to fig. 14 to 17, in the present embodiment, the lever structure of the fourth embodiment and the wedge 26 and the second adjusting screw 25' structure of the fifth embodiment are combined. The difference is that, as shown in fig. 13, the moving direction of the wedge-shaped pieces 26 on the first bracket 31 and the third bracket 33 is in the second direction Y, and the moving direction of the wedge-shaped pieces 26 on the second bracket 32 is in the first direction X. The ejector rod 15 is arranged on the side of the rotating plate 34 remote from the corresponding frame body of the adjusting frame 1.
Meanwhile, each of the adjustment structures adds a slide bearing structure, each of which includes a first guide shaft 41, a sleeve 42, and a connection plate 43, wherein the connection plate 43 is rotatably connected to the rotation plate 34 through a second guide shaft 45, and the rotation axis thereof is parallel to the rotation plate 34. The second guide shaft 45 is fixed to the rotating plate 34, and the connection plate 43 is connected to the second guide shaft 45 by means of a key slot, so that the connection plate 43 can rotate along with the second guide shaft 45 and can slide along the second guide shaft 45. The connecting plate 43 is sleeved on the periphery of the shaft sleeve 42 and fixed, the shaft sleeve 42 is sleeved on the periphery of the first guide shaft 41 and can slide relatively, and two ends of the first guide shaft 41 can be fixed with the corresponding frame body surface of the adjusting frame 1 through the shaft seat 44. The sliding direction of the sleeve 42 with respect to the first guide shaft 41 is the same as the moving direction of the corresponding wedge 26.
When the first adjusting screw or the second adjusting screw 25' rotates the rotating plate 34, the connecting plate 43 rotates relative to the rotating plate 34, and drives the first guiding shaft 41 (together with the shaft seat 44) to push the corresponding frame body of the adjusting frame 1, and in the process, the shaft sleeve 42 slides along the first guiding shaft 41.
By providing a slide bearing arrangement, the effect of lateral push-pull forces from movement of the wedge 26 can be further isolated. Alternatively, the fine tuning may be achieved by the structure of the fourth embodiment. The first guide shaft 41 and the second guide shaft 45 are perpendicular to each other, and the sliding bearing structure formed by the two-dimensional orthogonal sliding structure (the connecting plate 43 corresponds to a shaft sleeve on the second guide shaft 45) is self-adaptive to push or pull point to point, point to line and point to face. The device is particularly suitable for the case that the adjustment of the first dimension and the second dimension generates lateral thrust on the frame body of the third dimension or the case that the installation precision of the first dimension and/or the second dimension is not high.
Example seven
Referring to fig. 18, in the present embodiment, the difference from the fourth embodiment described above is that the second adjusting screw 25 is omitted, the rotating plate 34 is disposed on the side of the corresponding bracket away from the corresponding frame body of the adjusting frame 1, each first adjusting screw is used to rotate the rotating plate 34 toward the corresponding frame body surface away from the adjusting frame 1, and at this time, the force applied by the tension spring 311 is opposite to that in the first embodiment.
The adjustment structure further comprises a flexible member 27, such as a pull rope or a wire rope, the flexible member 27 passing through the respective bracket connecting the swivel plate 34 with the respective frame body of the adjustment frame 1. Due to the adoption of the lever structure, the flexible piece 27 is fixed on the rotating plate 34 of the lever and the corresponding frame body of the adjusting frame 1, so that the tension of the adjusting frame 1 which is originally similar to a bearing is in the opposite direction of the lever, and the flexible piece 27 is used for transmitting the adjusting displacement of the lever.
In the structure of the adjusting frame, due to the external arrangement of the adjusting screws, the flexible piece 27 in the second dimension and the third dimension can swing in one dimension or two dimensions, and when the flexible piece 27 is long enough, the swing amplitude is small, and no great lateral tension is generated on the adjusting frame 1.
Example eight
Referring to fig. 19, in the present embodiment, a difference from the seventh embodiment described above is that a multi-axis link 28 (a structure in which at least two links are rotatably connected) is employed instead of the flexible member 27, and the rotation axis of the multi-axis link 28 is parallel to the rotation axis of the corresponding rotation plate 34.
Preferably, the multi-axis links 28 can be connected to the surface of the swivel plate 34 remote from the corresponding frame body of the adjusting frame 1, thereby increasing the length of the multi-axis links 28 as much as possible without increasing the overall size, reducing the swing amplitude of the multi-axis links 28 in the second and third dimensions.
Example nine
Referring to fig. 20, in the present embodiment, the difference from the sixth embodiment described above is that the adjusting structure has two, two-dimensional adjustment is achieved, and at this time, the adjusting bracket 1 has only the first bracket body 11 and the second bracket body 12, which are matched with the adjusting structure.
Alternatively, any one of the first to eighth embodiments may be used as the adjustment structure.
