Description

Technical Field

[0001] This utility model belongs to the technical field of adjustment devices and optical systems, specifically relating to a multi-degree-of-freedom manual adjustment platform (four-dimensional adjustment) and an optical adjustment system including the multi-degree-of-freedom manual adjustment platform. Background Technology

[0002] Current multi-degree-of-freedom adjustment platforms all have corresponding adjustment mechanisms set in the corresponding directions, resulting in large space occupation, low utilization rate, and insufficient structural compactness.

[0003] If the existing technology adjusts in the vertical direction, then an adjustment mechanism that occupies a large space in the vertical direction will be set up, and it will move and apply force directly along the vertical direction, resulting in a relatively high overall height of the device in the vertical direction.

[0004] Patents such as 2017206327266, an arc-shaped tilt angle adjustment device, and 2014205283939, a two-dimensional independent adjustment platform tilt angle device, all have the problems described above.

[0005] The above background information is provided only to assist in understanding the inventive concept and technical solution of this utility model. It does not necessarily belong to the prior art of this utility model. In the absence of clear evidence that the above information was disclosed before the application date of this utility model, the above background information should not be used to evaluate the novelty and inventiveness of this utility model. Utility Model Content

[0006] In view of this, in order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide an improved multi-degree-of-freedom manual adjustment platform with a compact structure, high space utilization, and easy adjustment.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A multi-degree-of-freedom manually adjustable platform includes a first plate and a second plate. The first plate includes a base plate and a side plate. The second plate is located above the base plate. A first adjustment mechanism for adjusting the distance between the base plate and the second plate is provided between the base plate and the second plate. The first adjustment mechanism includes a first direction moving member, a second direction moving member, and a first adjustment member.

The first adjustment member is set along the first direction and moves along the first direction.

[0009] According to some preferred embodiments of the present invention, the first direction is parallel to the plate body, and the second direction is perpendicular to the plate body; the first direction and the second direction are perpendicular, and the bottom plate and the side plate are arranged perpendicularly. In this utility model, the first direction is defined as a horizontal direction (Y-axis direction), the second direction is a vertical direction (Z-axis direction), and the bottom plate and the second plate body are arranged horizontally.

[0010] According to some preferred embodiments of the present invention, a movable cavity is provided on the base plate for the first directional movable member to move, and the first directional movable member is accommodated in the movable cavity; the movable cavity extends through the side of the side plate, and the first adjusting member extends into the movable cavity from the side of the side plate.

The plane is defined by these three second-direction moving members, avoiding excessive constraints caused by setting too many second-direction moving members.

[0018] The first and second side adjusting members of this utility model enable the second plate to move in the vertical direction (the first and second side adjusting members are adjusted synchronously) or to deflect in the vertical direction (the first and second side adjusting members are adjusted asynchronously).

[0019] According to some preferred embodiments of the present invention, a guide groove extending in a first direction is provided on the second directional moving member corresponding to the first side adjusting member on the second plate. The guide groove is used to guide the second plate in cooperation with the second directional moving member on the first side adjusting member when the second plate moves horizontally.

Detailed Implementation

[0046] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0047] like Figure 1-8 As shown, the multi-degree-of-freedom manual adjustment platform of this embodiment includes a first plate 1, a second plate 2, a first adjustment mechanism, a second adjustment mechanism, a first reset member 81, and a second reset member 82. The first plate 1 includes a base plate 31 and a side plate 32, which are vertically arranged. The second plate 2 is located above the base plate 31, and the base plate 31 and the second plate 2 are horizontally arranged. The first adjustment mechanism and the first reset member 81 are disposed between the base plate 31 and the second plate 2. The first adjustment mechanism is used to adjust the distance (vertical direction) between the base plate 31 and the second plate 2, and the first reset member 81 is used to make the second plate 2 tend to move towards the base plate 31. The second adjustment mechanism and the second reset member 82 are disposed between the side plate 32 and the second plate 2. The second adjustment mechanism is used to drive the second plate 2 to move on the plane (horizontal plane) where the plate is located, and the second reset member 82 is used to make the second plate 2 tend to move towards the side plate 32.

[0048] The first adjustment mechanism includes a first direction moving member 61, a second direction moving member 62, and a first adjustment member 41. The first adjustment member 41 drives the first direction moving member 61 to move in the first direction. The movement of the first direction moving member 61 drives the second direction moving member 62 to move in the second direction. The first adjustment member 41 is set along the first direction and moves along the first direction. The first direction is parallel to the plate body, and the second direction is perpendicular to the plate body; the first direction is set as a horizontal direction (Y-axis direction), and the second direction is set as a vertical direction (Z-axis direction); the first direction and the second direction are perpendicular.

[0049] The base plate 31 has a moving cavity 311 for the first-direction moving member 61 to move within it. The first-direction moving member 61 is housed within the moving cavity 311. The moving cavity 311 extends through the side of the side plate 32, and the first adjusting member 41 extends into the moving cavity 311 from the side of the side plate 32. The top surface of the base plate 31 has a through hole extending through its thickness, and the top of the second-direction moving member 62 passes through the through hole and contacts the bottom of the second plate 2. The moving cavity 311 extends along the first direction, and the first-direction moving member 61 moves horizontally within the moving cavity 311, thereby causing the second-direction moving member 62 to rise or fall, thus adjusting the horizontal height of the second plate 2.

[0050] A driving groove 71 is provided on the first directional moving member 61, which drives the second directional moving member 62 to move in the second direction. The groove wall of the driving groove 71 has different horizontal heights along the first direction, and thus, through the movement of the first directional moving member 61, the second directional moving member 62 contacts different parts of the groove wall of the driving groove 71, driving the second directional moving member 62 to move in the vertical direction. Specifically, the driving groove 71 includes a receiving surface 72 and a driving surface 73 located on the side of the receiving surface 72. When the second directional moving member 62 is located on the receiving surface 72, the horizontal height of the second directional moving member 62 is at its lowest. When the second directional moving member 62 is removed from the receiving surface 72 and located on the driving surface 73, the horizontal height of the second directional moving member 62 is relatively increased. The receiving surface 72 is horizontally arranged and located at the lowest point of the driving groove 71. The horizontal height of the driving surface 73 gradually increases from the receiving surface 72 to both sides, that is, the driving surface 73 is inclined and faces upward and towards the receiving surface 72. Preferably, the angle between the driving surface 73 and the horizontal plane is 15-45° to avoid difficulties in lifting the second-direction moving member 62 due to an excessively large angle. More preferably, the angle between the driving surface 73 and the horizontal plane is 20-30°, and in this embodiment, it is preferably 26°.

[0051] The second adjustment mechanism includes a second adjustment member 42. An adjustment hole penetrating the thickness of the side plate 32 is provided along the first direction. After the second adjustment mechanism passes through the adjustment hole, it contacts the side of the second plate 2. The second adjustment member 42 is arranged along the first direction and moves along the first direction. That is, both the first adjustment member 41 and the second adjustment member 42 are arranged along the first direction and are parallel to each other. The corresponding adjustment surfaces (i.e., the driving hole 53 below) are all arranged on the side plate 32, which facilitates adjustment and operation.

[0052] The second adjustment mechanism is used to adjust the second plate 2 on a horizontal plane, including horizontal movement and deflection. The first adjustment member 41 and the second adjustment member 42 include an adjustment rod 51, an adjustment sleeve 52, and a fixing sleeve 55. The adjustment sleeve 52 is fitted onto the outer periphery of the adjustment rod 51. The adjustment rod 51 has external threads, and the inner wall of the adjustment sleeve 52 has internal threads. The external and internal threads cooperate to drive the adjustment rod 51 to move. The structures of the first adjustment member 41 and the second adjustment member 42 are basically the same; both drive the adjustment rod 51 to move through threaded engagement. The adjustment rod 51 of the first adjustment member 41 drives the first direction moving member 61 to move, and the adjustment rod 51 of the second adjustment member 42 drives the second plate 2 to move. The fixing sleeve 55 is fitted onto the outer periphery of the adjustment rod 51 and is used to fix the position of the adjustment rod 51 after it has moved into place by fasteners such as screws on the fixing sleeve 55.

[0053] The adjusting sleeve 52 is fixedly installed. The adjusting sleeve 52 of the first adjusting member 41 is fixed in the moving cavity 311, and the adjusting sleeve 52 of the second adjusting member 42 is fixed in the adjusting hole. One end of the adjusting rod 51 has a driving hole 53 for driving the adjusting rod 51 to rotate; the other end of the adjusting rod 51 is provided with a contact member 54, which is used to contact the side of the second plate 2. The contact member 54 is spherical. A gasket 11 is provided on the end face of the second plate 2 corresponding to the position of the spherical body.

[0054] The center lines of the first adjusting member 41 and the first directional moving member 61 are on the same straight line. The first directional moving member 61 is a cylinder, and the center line of the adjusting rod 51 coincides with that of the cylindrical first directional moving member 61. The second directional moving member 62 is a sphere. A shim 11 is provided at the bottom of the second plate 2 corresponding to the position of the sphere. The diameter of all shims 11 is larger than the diameter of the corresponding sphere.

[0055] In this embodiment, the first adjusting member 41 includes a first-side adjusting member and a second-side adjusting member located on two opposite sides of the manual adjusting platform. The number of second-direction moving members 62 in the first-side adjusting member and the second-side adjusting member are different. The first-side adjusting member includes one second-direction moving member 62, and the second-side adjusting member includes two second-direction moving members 62. The second-direction moving members 62 in the first-side adjusting member and the second-side adjusting member form an isosceles triangle distribution. That is, one side has one second-direction moving member 62, and the other side has two second-direction moving members 62, for a total of three second-direction moving members 62. The plane is defined by the three second-direction moving members 62, avoiding excessive constraints caused by setting too many second-direction moving members 62. Through the first-side adjusting member and the second-side adjusting member, the second plate can be moved in the vertical direction (synchronously adjusted by the first-side adjusting member and the second-side adjusting member) or deflected in the vertical direction (asynchronously adjusted by the first-side adjusting member and the second-side adjusting member).

[0056] The second plate 2 has a guide groove 21 extending along the first direction on the second direction moving member 62 corresponding to the first side adjusting member. The guide groove 21 is used to guide the second plate 2 in cooperation with the second direction moving member 62 on the first side adjusting member when the second plate 2 moves horizontally. The size of the guide groove 21 has a certain redundancy to avoid affecting the horizontal deflection of the second plate 2.

[0057] The second plate 2 is provided with a second adjustment mechanism at both ends of its end face near the side plate 32; the second reset member 82 is located in the middle of the two second adjustment mechanisms. The two ends of the end face of the side plate 32 are provided with second adjustment mechanisms, so that by adjusting the two second adjustment mechanisms, the second plate 2 can be controlled to move forward or backward along the Y-axis (the two second adjustment mechanisms adjust synchronously) or deflect in the horizontal plane (the two second adjustment mechanisms adjust asynchronously).

[0058] The first reset member 81 is perpendicular to the plate body and is used to pull the second plate body 2 vertically toward the base plate 31. The number and distribution of the first reset members 81 correspond to the second directional moving members 62. In this embodiment, there are three first reset members 81, arranged in an isosceles triangle, corresponding to the second directional moving members 62 in the first and second side adjusting members. The second reset member 82 is parallel to the plate body and is used to pull the second plate body 2 horizontally toward the side plate 32.

[0059] The first reset member 81 and the second reset member 82 include an elastic member 91 and limiting rods 92 located at both ends of the elastic member 91. The limiting rods 92 are parallel or perpendicular to the plate body, and their positions on the plate body are fixed. They move synchronously with the plate body to stretch the elastic member. The two limiting rods 92 of the first reset member 81 are located on the base plate 31 and the second plate body 2, respectively, and the elastic member 91 of the first reset member 81 passes through the base plate 31 and the second plate body 2. The two limiting rods 92 of the second reset member 82 are located on the side plate 32 and the second plate body 2, respectively. The limiting rods 92 are used to fix the two ends of the elastic member 91 to the plate body, so that the elastic member 91 is stretched during the adjustment process, and then the restoring force of the elastic member 91 pulls the plate body closer and returns it to its original position. The first plate body 1 and the second plate body 2 are provided with receiving grooves 93 for accommodating the elastic member 91. The size of the receiving grooves 93 is larger than the size of the elastic member 91 to avoid interference between the elastic member 91 and the plate body when the plate body deflects. For example, the receiving groove 93 on the second plate 2 corresponding to the second reset member 82 is trapezoidal, with the opening facing the side plate 32.

[0060] The optical adjustment system includes a multi-degree-of-freedom manual adjustment platform as described above. One of the first plate 1 or the second plate 2 is used to fix it on the platform, and the remaining one of the first plate 1 or the second plate 2 is used to install optical components. Both the first plate 1 and the second plate 2 have multiple mounting holes 10, allowing for the fixing or installation of the first plate 1 or the second plate 2, or the installation of optical components, as needed. Preferably, the first plate 1 is a mounting base, through which the four-dimensional adjustment platform can be horizontally or vertically mounted on the optical platform or worktable via its four mounting holes 10. The second plate 2 is an adjustment base, through which the optical components or laser accessories to be adjusted can be mounted via the mounting holes 10. Five tension and compression springs (first reset member 81 and second reset member 82) combine the mounting base and the adjustment base to form the four-dimensional adjustment platform. That is, the multi-degree-of-freedom manual adjustment platform in this embodiment includes at least four dimensions of adjustment: Y-axis, Z-axis, pitch angle (Z-axis deflection), and yaw angle (horizontal deflection).

[0061] The following is a brief description of the adjustment process of the multi-degree-of-freedom manual adjustment platform in this embodiment:

[0062] 1) Horizontal deflection

[0063] By rotating the adjusting rod 51 of the second adjusting member 42 on one of the side plates 32 to press against the second plate 2, the sway angle is adjusted, and the second plate 2 is swayed horizontally.

[0064] 2) Horizontal movement along the Y-axis

[0065] The Y-axis can be adjusted forward by simultaneously rotating the adjusting rods 51 of the two second adjusting parts 42 on the side plate 32 clockwise against the side of the second plate 2.

[0066] The Y-axis can be adjusted backward by simultaneously rotating the adjusting rods 51 of the two second adjusting members 42 on the side plate 32 counterclockwise, and then by pulling back the second resetting member 82.

[0067] 3) Pitch and yaw

[0068] By rotating the adjusting rod 51 of the first or second side adjusting member on the side plate 32 clockwise, the corresponding first direction moving member 61 is pressed against, causing the first direction moving member 61 to move within the moving cavity 311. This forward movement drives the second direction moving member 62 to move upward and press against the second plate 2 to adjust the pitch angle.

[0069] 4) Z-axis movement

[0070] By simultaneously rotating the adjusting rods 51 of the first and second side adjusting members on the side plate 32 clockwise, the corresponding first direction moving member 61 is pressed against the first direction moving member 61, causing the first direction moving member 61 to move forward in the moving cavity 311. The forward movement drives the second direction moving member 62 to move upward and press against the second plate 2, so that the second plate 2 moves upward at the same rate, and the Z-axis can be adjusted upward.

[0071] By simultaneously rotating the adjusting rods 51 of the first and second side adjusting members on the side plate 32 counterclockwise, the corresponding first direction moving member 61 is pressed against, causing the first direction moving member 61 to move backward in the moving cavity 311, and the second direction moving member 62 to fall downward. The downward adjustment of the Z-axis can be completed by pulling back the first reset member 81.

[0072] This utility model's multi-degree-of-freedom manual adjustment platform, by setting a first adjustment mechanism to change the direction of force application, allows the second plate 2 to be adjusted horizontally via the first adjustment member 41 when vertical movement is required. This reduces the vertical space occupied by the adjustment platform, resulting in a compact structure, high space utilization, and easy adjustment. This utility model's multi-degree-of-freedom manual adjustment platform can adjust the Y-axis, Z-axis, pitch angle, and yaw angle using only four adjustment members. It can be installed horizontally or vertically on an optical platform or working platform. By changing the size of the mounting holes, it can accommodate different optical components and laser accessories, enabling precise alignment of optical components and other laser accessories on the optical platform or working platform.
