Description

Technical Field

The utility model belongs to the technical field of optics experimental facilities and specifically relates to an alignment jig structure to and an optical system who has this light alignment jig structure of using.

Background

Optical alignment brackets are widely used in optical systems for fine adjustment of the position and angle of optical components.

In a conventional optical adjusting frame structure, referring to fig. 21 to 23, an adjusting screw 100 and an adjusting frame 200 are generally integrated, and for a multi-dimensional adjusting system, such as a three-dimensional adjusting system, a dimension two is established on the basis of a dimension one, and a dimension three is established on the basis of a dimension two. When adjusting dimension one, the base of the adjusting bracket 200 is directly connected with the optical platform, so that the structure is relatively stable, but when adjusting the upper dimension, especially dimension three, when manually adjusting, the adjusting screw 100 is rotated, so that a lateral push-pull force and a lateral rotating force are applied to the adjusting bracket 200. In addition, various bearings are generally used to make the adjustment frame 200, and the bearings are weak and cause instability of the entire adjustment system during adjustment. Especially in some high-precision adjustment application occasions, the whole adjustment system is greatly disturbed.

In addition, as mentioned above, since the adjustment screw 100 is generally used to push the axle carrier to perform the adjustment, if the adjustment screw 100 is used as a plane, the rotation of the adjustment screw 100 will generate a rotation force in the same direction on the adjustment frame 200, which reduces the stability of the whole adjustment system. So that spherical contact is generally adopted between the adjusting screw 100 and the adjusting bracket 200 at present, so as to reduce the influence of the rotation of the adjusting screw 100 on the adjusting bracket. However, since the spherical contact is adopted, the rigidity of the metal is poor, and after the adjusting bracket is used for a period of time, a concave pit 201 is formed on the contact surface of the adjusting bracket 200. Meanwhile, the spherical top end and the rotating shaft of the adjusting screw 100 are often difficult to be concentric, a pit 201 with a large area is easily formed on the adjusting frame 200, the existence of the pit 201 has great influence on the adjusting precision, such as increasing the rotating resistance and reducing the linearity, the non-concentricity of the pit 201 can generate a lateral thrust to the bearing, and the service life of the bearing is shortened.

Furthermore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

Example one

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 as to adjust the position of an optical component mounted on the optical platform.

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, there are three adjustment structures, which achieve three-dimensional adjustment. Each adjusting structure comprises a first adjusting screw as a rough adjusting screw, that is, the adjusting frame structure of this embodiment comprises a first dimension adjusting screw 21, a second dimension adjusting screw 22 and a third dimension adjusting screw 23, correspondingly, the adjusting frame 1 comprises a first frame body 11, a second frame body 12 and a third frame body 13, and the correspondence here refers to the correspondence of the number and the position. Wherein, first support body 11 is movably arranged on base 5, second support body 12 is movably arranged on first support body 11, and third support body 13 is movably arranged on second support body 12. First support body 11 can move on first direction X relative to base 5, realizes the regulation of dimension one, and second support body 12 can move on second direction Y relative to first support body 11, realizes the regulation of dimension two, and third support body 13 can move on third direction Z relative to second support body 12, realizes the regulation of dimension three to first direction X, second direction Y and two liang of mutually perpendicular of third direction Z. Between first support body and base 5, between second support body 12 and first support body 11 and between third support body 13 and second support body 12, can set up sliding fit's guiding mechanism respectively to inject the moving path of first support body 11, second support body 12 and third support body 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 bracket structure further comprises a bracket for setting the adjusting structure, in this embodiment, a first bracket 31, a second bracket 32 and a third bracket 33, and each bracket is independently and fixedly arranged on the base 5. Alternatively, two or three brackets may be made as a single bracket. The first dimension adjusting screw 21 passes through the first bracket 31 and is screwed therebetween, the top end of the first dimension adjusting screw 21 contacts with the surface of the first frame 11, so as to push the first frame 11 to move in the first direction X, and to move in one direction of the first direction X, and the reverse movement is realized by the restoring force of the elastic member such as a tension spring 311 (as shown in fig. 3, the first frame 11 and the base 5 are respectively connected, 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 threadedly coupled to the second bracket, and the top end of the second dimension adjusting screw 22 contacts the surface of the second frame 12, so as to push the second frame 12 to move in the second direction Y and move towards 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 coupling the second frame 12 and the base 5) in the second frame 12, in the same manner as the prior art. The third dimension adjusting screw 23 passes through the third bracket 33 and is threadedly coupled to the third bracket, and the top end of the third dimension adjusting screw 23 contacts with the surface of the third frame 13, so as to push the third frame 13 to move in the third direction Z, and to move in one direction of the third direction Z, the reverse movement is realized by the restoring force of the elastic member such as a tension spring 311 (connected to the second frame 12 and the third frame 13, respectively) in the third frame 13, and the restoring manner is the same as that of the prior art.

This achieves that the adjustment structures are independent of one another in each dimension. When manual adjustment is performed or the motor is adopted for driving, the shaking of hands and the motor cannot generate lateral push-pull force on the whole adjusting frame 1, and the only influence is the thrust force on the corresponding frame body when each adjusting screw rod is rotated. This configuration enables, to a large extent, isolation of non-accommodating dimensional judder.

Due to the adoption of the independent external arrangement of each adjusting structure, when the first dimension is adjusted, the surface contact mode of the first dimension adjusting screw 21 and the first frame body 11 is point and point, and when the second dimension is adjusted, the surface contact mode of the second dimension adjusting screw 22 and the second frame body 12 is point and line, because the contact position of the second dimension adjusting screw 22 and the second frame body 12 of the second dimension is driven to slide when the first dimension is adjusted, the point and line contact mode is formed, and the length of the line is the adjusting range of the first dimension; when the dimension three is adjusted, the adjustment of the dimension one and the dimension two can cause the contact between a point and a surface between the third dimension adjusting screw 13 of the dimension three and the third frame body 33, and the size of the surface is the adjusting range of the dimension one and the dimension two.

Example two

As mentioned above, since each first adjusting screw usually adopts a spherical surface to contact with the corresponding frame body surface of the adjusting frame 1, a pit may be formed on the corresponding frame body surface of the adjusting frame 1, and the service life of the whole adjusting frame structure is reduced. To solve this problem, an alternative solution is to reduce the dishing problem by reducing the tension of the tension spring to reduce the force between each adjusting screw and the corresponding body surface of the adjusting bracket 1. However, the reduction of the tension spring can also cause the reduction of the load or the reduction of the stability of the adjusting frame structure. Particularly, when each first adjusting screw is externally arranged, the point-line contact and the point-surface contact are formed by the dimension two and the dimension three, and the pit problem of the contact point is more prominent.

For this reason, in the present embodiment, referring to fig. 3, on the basis of the first embodiment, a first magnet a24 is disposed on each first adjusting screw, a second magnet 14 is disposed in the frame body corresponding to each first adjusting screw, and the first magnet a24 and the second magnet 14 are magnetically repulsive, so that the acting force between each first adjusting screw and the adjusting frame 1 is reduced, and the abrasion is reduced.

In FIG. 4, F ₁ : the tension of the tension spring 311 (which may be the elastic force of the spring); f ₂ : repulsion between the two magnets; f ₃ : each adjusting screw acts onAdjust the force on the corresponding body surface of the frame 1 and satisfy 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 b24 'is disposed on the base 5 and located in each frame body, and the magnetic attraction between the first magnet b24' and the second magnet 14 can also counteract the pressure between part of each first adjusting screw and the corresponding frame body surface of the adjusting frame.

In FIG. 5, F ₁ : the tension of the tension spring 311 (which may be the elastic force of the spring); f ₂ : the attraction between the two magnets; f ₃ : the force of the first adjusting screws acting on the respective frame body surface of the adjusting frame 1 and satisfying F ₃ ＝F ₁ -F ₂ 。

Example four

Referring to fig. 6 to 9, in the present embodiment, on the basis of the first embodiment, the adjusting structure of each dimension further includes a second adjusting screw a25, the first adjusting screw serves as a coarse adjusting screw, and the first adjusting screw only passes through the corresponding bracket, and may not generate 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 axis of rotation of each rotary plate 34 is perpendicular to the adjustment direction of the respective dimension, so that each rotary plate 34 is rotatably closer to or farther from the respective shelf surface of the adjustment shelf 1. As shown in fig. 6, the rotation axes of the rotation plates 34 on the first and second supports 31 and 32 are both in the third direction Z, and the rotation axis of the rotation plate 34 on the third support 33 is in the first direction X. Each first adjustment 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 top end thereof pushes the corresponding frame body surface of the adjusting frame 1, thereby performing coarse adjustment, and simultaneously, the rotating plate 34 can be rotated to approach the corresponding frame body.

The rotary plate 34, the second adjusting screw a25 and the corresponding bracket constitute a lever. Each second adjusting screw a25 is used as a fine adjusting screw, passes through the corresponding bracket and is in threaded connection with the corresponding bracket, and the top end of the second adjusting screw a25 is abutted with one 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 a25 acts on the lever, the rotating plate 34 can be pushed to rotate relative to the corresponding support, the corresponding first adjusting screw is driven to gradually push the corresponding support body of the adjusting frame 1, and therefore adjusting precision is improved. Meanwhile, the rotating force of the second adjusting screw rod a25 and the force in other non-acting directions can be isolated through the lever, and the whole adjusting frame structure cannot be influenced.

EXAMPLE five

Referring to fig. 10 to 13, in the present embodiment, the difference from the first embodiment is that the adjustment structure for each dimension further includes a second adjustment screw b25', and the first adjustment screw is used as a coarse adjustment screw. The adjustment structure for each dimension further comprises a wedge 26, and the second adjustment screw b25' serves as a fine adjustment screw for adjusting the movement of the wedge 26. The wedge-shaped piece 26 means that the thickness of the piece is gradually reduced in one direction, formed by one of the surfaces being a slope.

Each wedge-shaped piece 26 is arranged between the corresponding first adjusting screw and the frame body surface of the adjusting frame 1, each frame body surface of the adjusting frame 1 is further provided with an ejector rod 15, the ejector rods 15 and the corresponding first adjusting screws are respectively abutted to two opposite sides of the wedge-shaped pieces 26, and one side of the abutted ejector rods 15 is one side of the inclined plane of the wedge-shaped pieces 26. When each first adjusting screw pushes the corresponding wedge 26 to the corresponding frame body surface of the adjusting frame 1, the wedge 26 pushes the corresponding frame body of the adjusting frame 1 through the mandril 15, so as to perform rough adjustment.

The second adjusting screw b25' is used for driving the wedge 26 to move linearly, and the moving direction of the wedge 26 is perpendicular to the adjusting direction of the corresponding dimension. As shown in fig. 10, the moving direction of the wedge 26 on the first bracket 31 and the second bracket 32 is in the third direction Z, and the moving direction of the wedge 26 on the third bracket 33 is in the first direction X. The distance between the position that corresponds with the top of ejector pin 15 on wedge piece 26's the inclined plane and the corresponding support body surface can be changed in wedge piece 26's removal, and the moving direction of accessible control wedge piece 26 from this for wedge piece 26's removal in-process, above-mentioned distance reduces gradually, promotes ejector pin 15 and removes to the direction of keeping away from first adjusting screw, and then ejector pin 15 promotes corresponding support body gradually, thereby carries out the fine tuning.

In order to facilitate the movement of the wedge 26 by the second adjustment screws b25', each second adjustment screw b25' passes through the corresponding bracket and is screw-coupled therebetween. And each bracket is also provided with a fixed seat 35, the top end of each second adjusting screw b25 'is abutted against a sliding block 36, and the sliding block 36 is arranged between the second adjusting screw b25' 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 connected with the guide rod 37 in a sliding mode, an elastic piece 38 is arranged on each guide rod 37, and two ends of each elastic piece 38 are respectively abutted against the sliding block 36 and the fixed seat 35, so that the sliding block 36 keeps the trend of moving towards the direction of the second adjusting screw b 25'.

In the adjusting structure of the present embodiment, the torsion of the rotation of the first adjusting screw does not affect the adjusting bracket 1, but is isolated by the wedge 26.

EXAMPLE six

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 b25' structure of the fifth embodiment are combined. The difference is that, as shown in fig. 13, the moving direction of the wedge 26 on the first bracket 31 and the third bracket 33 is in the second direction Y, and the moving direction of the wedge 26 on the second bracket 32 is in the first direction X. The lifting rod 15 is arranged on the side of the rotary plate 34 remote from the respective body of the adjusting carriage 1.

Meanwhile, each adjusting structure is added with a sliding bearing structure, each sliding bearing structure comprises a first guide shaft 41, a shaft sleeve 42 and a connecting plate 43, wherein the connecting plate 43 is rotatably connected with the rotating plate 34 through a second guide shaft 45, and the rotating axis of the connecting plate is parallel to the rotating plate 34. The second guide shaft 45 is fixed to the rotating plate 34, and the connecting plate 43 is connected to the second guide shaft 45 in a key-and-groove manner, so that the connecting 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 guiding shaft 41 and can slide relatively, and two ends of the first guiding shaft 41 can be fixed on the corresponding frame body surface of the adjusting frame 1 through the shaft seat 44. The sliding direction of the bushing 42 with respect to the first guide shaft 41 is the same as the moving direction of the corresponding wedge 26.

When the rotating plate 34 is rotated by the first adjusting screw or the second adjusting screw b25', the connecting plate 43 rotates relative to the rotating plate 34, and the first guiding shaft 41 (together with the shaft seat 44) is driven to push the corresponding frame body of the adjusting frame 1, in the process, the shaft sleeve 42 slides along the first guiding shaft 41.

By providing a sliding bearing arrangement, the effect of lateral push-pull forces caused by the movement of the wedge 26 can be further isolated. Alternatively, the structure of the fourth embodiment may be adopted as a manner of achieving fine adjustment. The first guide shaft 41 and the second guide shaft 45 are perpendicular to each other, and the sliding bearing structure formed by the first guide shaft 41 and the second guide shaft 45 is a two-dimensional orthogonal sliding structure (the connecting plate 43 is equivalent to a sleeve on the second guide shaft 45), and self-adaptive point-to-point, point-to-point and point-to-surface pushing or pulling are carried out. The adjusting mechanism is particularly suitable for adjusting the first dimension and the second dimension to generate lateral thrust on the rack body in the third dimension, or when the mounting accuracy 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 is that the second adjusting screw a25 is omitted, and the rotating plate 34 is disposed on the side of the corresponding bracket away from the corresponding frame body of the adjusting frame 1, and each first adjusting screw is used to rotate the rotating plate 34 toward the corresponding frame body surface away from the adjusting frame 1, at this time, the force applied by the tension spring 311 is opposite to that in the first embodiment.

The adjusting structure further comprises a flexible member 27, such as a pull cord or a wire rope, wherein the flexible member 27 passes through the corresponding bracket to connect the rotating plate 34 with the corresponding bracket body of the adjusting bracket 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 pulling force of the adjusting frame 1 similar to a bearing originally is the opposite direction of the lever, and the flexible piece 27 is used for transmitting the adjusting displacement of the lever.

In the adjusting bracket structure, due to the external arrangement of each adjusting screw, the flexible parts 27 in the dimension two and the dimension three can swing in one dimension or two dimensions, when the flexible parts 27 are long enough, the swing amplitude can be small, and great lateral tension cannot be generated on the adjusting bracket 1.

Example eight

Referring to fig. 19, in the present embodiment, the difference from the seventh embodiment described above is that a multi-axis link 28 (a structure in which at least two links are rotationally connected) is used instead of the flexible member 27, and the rotational axis of the multi-axis link 28 is parallel to the rotational axis of the corresponding rotary plate 34.

Preferably, the multi-axis connecting rod 28 may be connected to a surface of the rotating plate 34 away from the corresponding body of the adjusting frame 1, thereby increasing the length of the multi-axis connecting rod 28 as much as possible and reducing the swing amplitude of the multi-axis connecting rod 28 in the two and three dimensions without increasing the overall size.

Example nine

Referring to fig. 20, in the present embodiment, the difference from the sixth embodiment is that the adjusting structure has two, and two-dimensional adjustment is realized, and the adjusting frame 1 only has the first frame body 11 and the second frame body 12, and is matched with the adjusting structure.

Alternatively, the adjustment structure may use any one of embodiment one to embodiment eight.
