Therefore, they should not be understood as limitations on the present invention.
[0041] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0042] Embodiment 1:
[0043] like Figure 1 As shown, Embodiment 1 of the present invention provides an adjuster for the angle of a precision platform, comprising a support structure frame 1 and two adjusting devices 2;
[0044] The support structure frame 1 includes a top plate 11, a bottom plate 12 and a connecting rod 13, one end of the connecting rod 13 is connected to the lower surface of the top plate 11, and the other end of the connecting rod 13 is connected to the upper surface of the bottom plate 12, and the upper surface of the top plate 11 is arranged parallel to the lower surface of the bottom plate 12, and the top plate 11 is used to carry the platform to be adjusted;
[0045] The adjusting device 2 comprises a lower base 21, a ball head rod 22, a screw rod 23, an adjusting rod 24, a connecting rod assembly 25 and an upper base 26; the ball head end of the ball head rod 22 is movably connected to one end of the lower base 21, and the other end of the ball head rod 22 is fixedly connected to one end of the screw rod 23; one end of the adjusting rod 24 is hollow and extends along the axial direction, and one end of the adjusting rod 24 is sleeved on the other end of the screw rod 23; the other end of the adjusting rod 24 is connected to one end of the connecting rod assembly 25, and the other end of the connecting rod assembly 25 is rotatably connected to the upper base 26;
[0046] Wherein, under the action of external force, the adjusting rod 24 rotates along the screw rod 23 to adjust the depth of the screw rod 23 entering the adjusting rod 24, thereby adjusting the length of the adjusting device 2;
[0047] Among them, the upper base 26 of one adjusting device 2 is connected to the first side surface of the top plate 11, and the lower base 21 of the adjusting device 2 is connected to the platform on the same side; the upper base 26 of the other adjusting device 2 is connected to the second side surface of the top plate 11, and the lower base 21 of the adjusting device 2 is connected to the platform on the same side, and the first side surface intersects with the second side surface.
[0048] like Figure 1 As shown, the core structure in the regulator of the embodiment of the present invention is the regulating device 2. One end of the regulating device 2 of the present invention is fixed to the platform through the lower base 21, and the other end is connected and fixed to the support structure frame 1 through the upper base 26. The length of the regulating device 2 is adjusted by adjusting the distance between the regulating rod 24 and the screw 23. When adjusting the length of the regulating device 2, the upper base 26 of the regulating device 2 directly generates a thrust or pull force on the top plate 11 of the support structure frame 1, so that the top plate 11 of the support structure frame 1 is flipped along the adjustment direction at a small angle within the elastic deformation range of the support structure frame 1. The platform to be adjusted is set on the top plate 11 of the regulator of the embodiment of the present invention. The flipping of the top plate 11 drives the platform to be adjusted to flip together, thereby realizing the adjustment of the small angle of the platform. By adjusting the position between the regulating rod 24 and the screw 23. When the platform flip angle reaches the target angle to be adjusted, the regulating rod 24 and the screw 23 are fixed, so that the platform can be set to the target angle to be adjusted for a long time.
[0049] like Figure 2-3 In order to achieve the length adjustment of the adjustment device 2 of the present invention, the present invention is provided with a ball head rod 22, and the ball head end of the ball head rod 22 is movably connected to one end of the lower base 21; the connecting rod assembly 25 includes a rotating block 252, and the upper base 26 includes a rotating shaft 261. Through the cooperation of the rotating block 252 and the rotating shaft 261, the other end of the connecting rod assembly 25 is rotatably connected to the upper base 26, and the connection cooperation at the ball head rod 22 can self-rotate to adapt the connecting rod 251 axially to the force direction of the device to ensure the accuracy of the device adjustment. In addition, the embodiment of the present invention sets an adjustment device 2 in two different directions respectively. When the platform needs to be adjusted to a certain special spatial angle for setting, the adjustment device 2 is installed and adjusted in two directions, so that the platform can be flipped at a small angle in space. The present invention sets an adjustable length adjustment device 2 in two intersecting directions, and fixes the adjustment device 2 and the support structure frame 1 on the platform, and adjusts the small angle of the platform with the help of the support structure frame 1. It is worth noting that the preset positions of the adjusting rod 24 and the screw 23 of the present invention are set according to the angle that the platform needs to be adjusted. When the platform is adjusted to the required angle, the relative positions of the adjusting rod 24 and the screw 23 correspond to the preset positions of the embodiments of the invention.
[0050] In order to illustrate the complete scheme of the present invention, the specific details of the present invention are explained in detail below. Furthermore, the interior of the adjusting rod 24 of the present invention is provided with an internal thread, and the other end of the screw 23 is provided with an external thread. The inner diameter of the adjusting rod 24 is equal to the outer diameter of the screw 23. The adjusting rod 24 is sleeved on the screw 23, and the external thread matches the internal thread, so that the adjusting rod 24 drives the connecting rod assembly 25 to move axially along the screw 23.
[0051] The adjusting rod 24 of the embodiment of the present invention is provided with an internal thread inside, and the screw rod 23 is provided with an external thread outside; the adjusting rod 24 is sleeved on the screw rod 23 and the adjusting rod 24 is rotated so that the screw rod 23 is screwed into or out of the adjusting rod 24, so that the length of the adjusting device 2 is shortened or extended, thereby realizing the adjustment of the platform. When the length of the adjusting device 2 is shortened, the adjusting device 2 generates a pulling force on the top plate 11 of the supporting structure frame 1, and pulls the platform through the upper base 26, so that the angle of the top plate 11 is adjusted downward within the range allowed by the elasticity, thereby driving the angle of the platform to be adjusted downward together; when the length of the adjusting device 2 is extended, the adjusting device 2 generates a thrust force on the top plate 11 of the supporting structure frame 1, and pushes the platform through the upper base 26, so that the angle of the top plate 11 is adjusted upward within the range allowed by the elasticity, thereby driving the angle of the platform to be adjusted upward together; in addition, arranging the adjusting device 2 in two different directions of the platform can effectively realize a slight flipping of the platform in each direction; the internal thread of the adjusting rod 24 and the external thread of the screw rod 23 in the embodiment of the present invention can effectively achieve the purpose of continuously adjusting the length of the adjusting device 2, thereby improving the accuracy of the slight angle adjustment of the platform.
[0052] The other end of the connecting rod assembly 25 of the embodiment of the present invention is rotatably connected to the upper base 26. In order to realize the rotation between the connecting rod assembly 25 and the upper base 26, as shown in FIG. Figure 4-5As shown, the upper base 26 of the present invention includes a rotating shaft 261 and a base plate 262; the connecting rod assembly 25 includes a connecting rod 251, a rotating block 252, a connecting plate 253 and a connecting rod bearing 254; wherein the base plate 262 includes a first connecting portion 2621, a first fixing portion 2622 and a second connecting portion 2623, and the rotating block 252 includes a wedge-shaped portion 2521 and a hollow rotating cylinder portion 2522; one end of the first connecting portion 2621 is connected to one end of the first fixing portion 2622 at a first preset angle, one end of the second connecting portion 2623 is connected to the other end of the first fixing portion 2622 at a second preset angle, and the first connecting portion 2621 is connected to one end of the first fixing portion 2622 at a second preset angle. 621 and the second connecting part 2623 are provided with a shaft mounting hole 2624; both ends of the hollow rotating cylinder part 2522 of the rotating block 252 are aligned with the shaft mounting hole 2624, so that the rotating shaft 261 is inserted into the shaft mounting hole 2624 and the hollow rotating cylinder part 2522 in sequence; one end of the wedge-shaped part 2521 is connected to the middle part of the hollow rotating cylinder part 2522, and a connecting plate 253 is provided on the other end face of the wedge-shaped part 2521, one end of the connecting rod 251 is fixed on the connecting plate 253, and the connecting rod bearing 254 is sleeved on the other end of the connecting rod 251, and the adjusting rod 24 is axially connected to the connecting rod 251 through the connecting rod bearing 254.
[0053] like Figure 3-5 As shown, the adjusting device 2 of the embodiment of the present invention is fixed to the side of the top plate 11 of the supporting structure frame 1 through the first fixing portion 2622; and, the first connecting portion 2621 and the second connecting portion 2623 are provided with a rotating shaft mounting hole 2624, and the two ends of the hollow rotating cylinder portion 2522 of the rotating block 252 are aligned with the rotating shaft mounting hole 2624, and one end of the rotating shaft 261 is inserted into the rotating shaft mounting hole 2624 of the first connecting portion 2621, the rotating shaft mounting hole 2624 of the hollow rotating cylinder portion 2522 and the second connecting portion 2623 in sequence and fixed; and then one end of the connecting rod 251 is fixed to the wedge-shaped portion 2521 of the rotating block 252 through the connecting plate 253, so that the connecting rod assembly 25 can effectively realize the rotation along the rotating shaft 261. It is worth noting that the wedge-shaped portion 2521 and the hollow rotating cylinder portion 2522 of the embodiment of the present invention can be integrally formed, or can be separately arranged to form the rotating block 252; the first connecting portion 2621, the first fixing portion 2622 and the second connecting portion 2623 can also be integrally formed, or can be separately arranged and spliced into the base plate 262; and the first preset angle and the second preset angle are set according to actual conditions, usually set to 90°.
[0054] In order to enable the adjustment device 2 to push or pull the platform and adjust the angle of the platform, the present invention is provided with a lower base 21, and the lower base 21 includes a fixed plate 211 and a connecting block 212, and the connecting block 212 is bent at a third preset angle along the middle, and one end of the connecting block 212 is connected to the upper surface of the fixed plate 211, and the other end of the connecting block 212 is provided with a ball head mounting hole 2121 for connecting to the ball head end of the ball head rod 22.
[0055] like Figure 6 As shown, the lower base 21 includes a fixing plate 211 and a connecting block 212. One end of the connecting block 212 is fixed on the fixing plate 211. The connecting block 212 and the fixing plate 211 can be bonded, screwed or integrally formed. The other end of the connecting block 212 is connected to the ball end of the ball head rod 22 through the ball head mounting hole 2121. In order to realize the rotation of the ball head rod 22 in all directions, the connecting block 212 of the embodiment of the present invention is bent at a third preset angle along the middle. It is worth noting that the third preset angle of the present invention is set according to actual conditions. The best third preset angle corresponds to the bending angle of the connecting block 212 when the ball head rod 22 just intersects with the connecting end face of the connecting block 212 in the natural setting state (the natural state corresponds to the state where the length of the adjusting device 2 is not adjusted).
[0056] In order to calculate the shortening or lengthening length of the adjusting device 2 according to the embodiment of the present invention, as shown in FIG. Figure 7 As shown, the present invention also includes a dial 3, and an adjustment mark 4 is provided at the end of the adjusting rod 24 and is located on the side where the adjusting rod 24 is connected to the connecting rod 251; a connecting rod mounting hole is provided at the center of the dial 3, and the connecting rod 251 is inserted into the connecting rod mounting hole and fixed to the dial 3.
[0057] The dial plate 3 of the embodiment of the present invention is fixed on the connecting rod 251, and the connecting rod 251 is fixed on the upper base 26. The connecting rod 251 and the dial plate 3 are relatively fixed, and the connecting rod 251 and the dial plate 3 will not rotate (the connecting rod assembly 25 can rotate around the rotating shaft 261, but cannot rotate). When the length of the adjusting device 2 is adjusted, the length adjusted by the adjusting device 2 can be read by setting the adjustment mark 4 on the adjusting rod 24 and the dial plate 3 fixed on the connecting rod 251.
[0058] like Figure 8 As shown, the present invention also includes a first set screw 5 and a second set screw 6. The screw rod 23 is provided with a first set screw mounting hole, and the adjusting rod 24 is provided with a second set screw mounting hole. The first set screw 5 matches with the first set screw mounting hole to facilitate the fixation of the ball head rod 22 and the screw rod 23. The second set screw 6 matches with the second set screw mounting hole to fix the adjusting rod 24 on the screw rod 23.
[0059] Among them, the present invention sets a second set screw mounting hole on the adjustment rod 24, and the second set screw 6 matches the second set screw mounting hole. When the adjustment device 2 adjusts the platform to the required angle, the second set screw 6 is installed in the second set screw mounting hole to fix the adjustment rod 24 and the screw 23 so that the platform can be permanently fixed at the required angle. In addition, the other end (non-ball end) of the ball head rod 22 of the present invention needs to be fixed with one end of the screw 23. The other end of the ball head rod 22 of the present invention is provided with a thread, and the end of the screw 23 connected to the ball head rod 22 is provided with an internal thread to facilitate the connection between the ball head rod 22 and the screw 23. When the other end of the ball head rod 22 is screwed into the screw 23, the first set screw 5 is installed in the first set screw mounting hole, which can avoid the ball head rod 22 being screwed out of the screw 23 during use, causing a certain error in the adjustment of the angle of the platform to be adjusted.
[0060] In the actual process of adjusting the length of the adjusting device 2, the platform itself may be placed on an uneven surface. At this time, the platform itself is not in a horizontal state, and it is difficult to achieve precise adjustment of the platform's minute angle through the adjusting device 2 of the present invention. For example, the adjuster of the present invention is placed on the ground, and the platform to be adjusted is placed on the top plate 11 of the supporting structure frame 1. At this time, when we need to adjust the platform to be adjusted, due to the uneven ground, we cannot know the inclination angle of the ground, making the minute angle of the platform to be adjusted inaccurate. Based on this, Fig. 9 As shown, the present invention further includes a first gyroscope 7, a second gyroscope 8 and a third gyroscope 9; the first gyroscope 7 is arranged on the upper surface of the top plate 11, and is used to measure the inclination angle between the top plate 11 and the horizontal plane, and the second gyroscope 8 and the third gyroscope 9 are respectively arranged on two adjustment devices 2, and are used to measure the inclination angle between the adjustment device 2 and the platform. It is worth noting that the first gyroscope 7 of the embodiment of the present invention can be properly adjusted in position according to actual conditions. In order to avoid the conflict between the position of the plane to be adjusted and the first gyroscope 7 when the plane to be adjusted is placed on the top plate 11, it can be arranged on the side of the top plate, or the first gyroscope 7 can be clamped by an external clamping device, and it is always kept in a relatively static state with the top plate. It is only necessary to ensure that the first gyroscope 7 can always measure the angle between the top plate 11 and the horizontal plane.
[0061] The upper surface of the top plate 11 of the support structure frame 1 of the present invention is arranged parallel to the lower surface of the bottom plate 12, and the first gyroscope 7 is arranged on the upper surface of the top plate 11. The lower surface of the bottom plate 12 of the support structure frame 1 of the present invention is placed on the platform, and the first gyroscope 7 can measure the inclination angle between the upper surface of the top plate 11 (or the lower surface of the bottom plate 12) and the horizontal plane. The platform to be measured is arranged on the upper surface of the top plate 11 and is always in close contact with the upper surface. When the first gyroscope measures the inclination angle between the upper surface of the top plate 11 and the horizontal plane, the inclination angle between the platform to be measured and the horizontal plane can actually be accurately measured. When the length of the adjustment device 2 of the present invention is not adjusted, the device of the present invention is in a natural state, and the platform to be adjusted is naturally in close contact with the upper surface of the top plate 12 of the support structure frame 1. By measuring the inclination angle between the upper surface of the top plate 11 and the horizontal plane, the initial inclination angle between the platform to be adjusted and the horizontal plane can be known.
[0062] An initial horizontal reference plane (horizontal plane) can be set for the platform of the present invention through the first gyroscope 7, and the relative tilt angle that needs to be adjusted for the platform of the present invention can be calculated through the initial tilt angle of the platform and the target angle that needs to be adjusted in the end; the relative tilt angle is decomposed to calculate the target length that needs to be adjusted for each of the two adjustment devices 2, and the length of the adjustment device 2 is adjusted to the target length. At the same time, the tilt angle of the adjusted platform can be detected by the first gyroscope 7, and the platform can be further fine-tuned through the angle display of the platform so that the final tilt angle of the platform to be adjusted is consistent with the target tilt angle.
[0063] The present invention sets an adjustable adjustment device 2 in two intersecting directions, and fixes the adjustment device 2 and the support structure frame 1 on the platform. Within the allowable range of elastic deformation, the support structure frame 1 is used to adjust a small angle in any direction of the platform to be adjusted. It is worth noting that the present invention is only applicable to the adjustment of a precision platform. Based on the elastic deformation range of the support structure frame, it is difficult to adjust a large angle of the platform to be adjusted.

[0065] Compared with the first embodiment of the present invention, the embodiment of the present invention further provides a method for using the regulator for the precision platform angle, such as Fig.10 As shown, including:
[0066] Step 201: fix the regulator on the bottom surface, place the platform to be adjusted on the upper surface of the regulator top plate 11, and use the first gyroscope 7 to measure the initial inclination angle of the platform to be measured and the horizontal plane.
[0067] Among them, in the process of using the regulator of the present invention, it is first necessary to install the regulator of the embodiment of the present invention on the bottom surface (for example: the ground). The present invention sets the adjustment device 2 in two directions, and the platform to be adjusted is fixed on the upper surface of the top plate 11 of the supporting structure frame 1. By adjusting the length of the adjustment device 2, the top plate 11 is pulled or pushed, and the slight angle of the platform is adjusted within the range allowed by the elastic deformation. It is worth noting that in principle, the embodiment of the present invention only needs to set the adjustment device 2 in two directions to achieve the adjustment of the slight angle of the platform in any direction. However, in complex application scenarios, it is also possible to increase the number of adjustment devices 2, install the adjustment device 2 in multiple directions of the platform supporting structure frame 1, and adjust the angle in multiple directions. To achieve the flipping of the platform to be adjusted at a special slight angle in space.
[0068] Step 202: Obtain the target angle of the platform to be adjusted, calculate the relative tilt angle that needs to be adjusted for the platform to be adjusted by using the initial tilt angle and the target angle, and use the second gyroscope 8 and the third gyroscope 9 to respectively measure the initial tilt angles of the two adjusting devices 2 and the platform to be adjusted before the adjusting devices are adjusted, as well as the initial lengths of the two adjusting devices 2.
[0069] In order for the embodiment of the present invention to accurately know the tilt angle adjusted by the platform, it is first necessary to know the initial tilt angle of the platform (the tilt angle before adjustment). The embodiment of the present invention measures the tilt angle of the platform before adjustment through the first gyroscope 7. Based on the basic principle of the gyroscope, no explanation is given here. It is worth noting that the process and principle of obtaining the tilt angle of the platform and the horizontal plane before the adjustment device 2 is not adjusted in the present invention have been described above and will not be repeated here. In addition, the embodiment of the present invention is mainly used for precise adjustment of precision platforms for small angles, and the relative tilt angle of the embodiment of the present invention is usually very small.
[0070] The second gyroscope 8 and the third gyroscope 9 of the embodiment of the present invention are mainly used to measure the initial tilt angle between the two adjusting devices 2 and the platform (actually refers to the angle between the adjusting devices 2 and the platform), and the initial length of the two adjusting devices 2 before being fixed on the platform and adjusted.
[0071] Step 203: Decompose the relative tilt angle to obtain the target lengths of the two adjustment devices 2, and adjust the lengths of the two adjustment devices 2 to the target lengths.
[0072] Since certain errors are unavoidable in the calculation or adjustment process, after adjusting the lengths of the two adjustment devices 2 to the target lengths, the embodiment of the present invention further includes detecting and verifying the angle of the adjusted platform through the first gyroscope 7. The adjusted platform is fine-tuned through the adjustment device 2, so that the final tilt angle of the platform to be adjusted in the embodiment of the present invention is the same as the target angle.
[0073] The present invention sets an adjustable adjustment device 2 in two intersecting directions, and fixes the adjustment device 2 and the support structure frame 1 on the platform. Within the allowable range of elastic deformation, the support structure frame 1 is used to adjust a small angle in any direction of the platform to be adjusted. It is worth noting that the present invention is only applicable to the adjustment of a precision platform. Based on the elastic deformation range of the support structure frame, it is difficult to adjust a large angle of the platform to be adjusted.
[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
