Two-dimensional turntable

Abstract

The application provides a two-dimensional rotary table, belonging to the technical field of detection tooling. The two-dimensional rotary table comprises a first rotary component and a second rotary component. The first rotary component comprises a bottom plate, a support frame, a first driving element and an outer frame. The support frame is arranged on the top of the bottom plate. The second rotary component comprises a second driving element, an inner frame and a mounting plate. The second driving element is mounted in the outer frame. By arranging the bottom plate, the support frame, the first driving element and the outer frame, the rotation of the second rotary component in the interior can be driven to adjust the angle. Meanwhile, the second driving element, the inner frame and the mounting plate can drive the detected angle sensor mounted on the mounting plate to rotate again. The transmission direction is perpendicular to the direction of the outer frame. Thus, the rotation in two directions can be synchronized to reach the designed angle to detect the angle error of the angle sensor feedback. The detection ability and the detection efficiency are greatly improved.

Description

Technical Field

[0001] This application relates to the field of testing tooling, specifically to a two-dimensional rotary table. Background Technology

[0002] Unmanned vehicles, or URMs for short, are devices operated using radio remote control equipment and their own program control devices, or autonomously operated completely or intermittently by an onboard computer. These include unmanned aerial vehicles, unmanned vehicles, and robotic dogs. However, different URMs are equipped with different sensors for different purposes, and each sensor requires performance testing to ensure its reliability.

[0003] Currently, when detecting the angle feedback from some sensors, traditional turntables mostly rotate in one direction, which is not comprehensive enough. Alternatively, they have overly complex mechanical structures, which may lead to large errors in the turntable itself, thus raising doubts about the accuracy of the detection results. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a two-dimensional turntable, which aims to improve the problems mentioned in the background art.

[0005] This application provides a two-dimensional turntable including a first rotating component and a second rotating component.

[0006] The first rotating assembly includes a base plate, a support frame, a first driving component, and an outer frame. The support frame is disposed on the top of the base plate. The first driving component includes a housing, a rotating plate, and a servo motor. The housing is fixedly connected to the top of the support frame. The rotating plate is rotatably disposed inside the housing. The servo motor is installed on the outside of the housing and is drivenly connected to the rotating plate. One side of the outer frame is fixedly connected to the rotating plate.

[0007] The second rotating assembly includes a second driving member, an inner frame, and a mounting plate. The second driving member is installed inside the outer frame, and the inner frame is rotatably disposed between the second driving member and the outer frame. The first driving member and the second driving member are perpendicular to each other, and the mounting plate is installed inside the inner frame.

[0008] In one specific implementation, a bearing seat is mounted on the other side of the outer frame, and the bearing seat is disposed on top of another support frame.

[0009] In the above implementation process, a bearing seat is set on the first driving member on the opposite side of the first driving member to cooperate with the first driving member to drive the outer frame to rotate stably to the required angle.

[0010] In one specific implementation, a worm gear is fixedly connected to the output end of the servo motor, and a worm wheel is fixedly sleeved on the rotating plate. The worm gear and the worm wheel mesh with each other, and the second driving member has the same structure as the first driving member.

[0011] In the above implementation process, by setting the worm and worm wheel to mesh, the servo motor is started to drive the worm to rotate, the worm meshes and drives the worm wheel to rotate, and the worm wheel drives the rotating plate to rotate, thus realizing the transmission connection. The second driving component has the same structural principle as the first driving component, so the specific structure of the second driving component will not be described in detail.

[0012] In one specific implementation, the outer frame includes side panels and connecting corner panels, the connecting corner panels being fixedly connected between the two side panels.

[0013] In the above implementation process, by setting side panels and connecting corner panels, the side panels are joined together to form a frame, and the connecting corner panels are used to connect the joints to form a stable frame structure.

[0014] In one specific implementation, the side plate has structural holes.

[0015] In the above implementation process, by opening structural holes, it is convenient to strengthen the structural strength on the one hand, and reduce the weight on the other.

[0016] In one specific implementation, one side of the inner frame is rotatably connected to the outer frame via a connecting bearing and is coaxial with the second drive component.

[0017] In the above implementation process, by setting structural holes, the two driving components can drive the inner frame to rotate stably.

[0018] In one specific implementation, the mounting plate has through holes and mounting holes, and there are multiple mounting holes.

[0019] In the above implementation process, through holes are made to allow different models and sizes of sensors to pass through, then the mounting surface is attached to the mounting plate, and then bolts are used to fix it through the mounting holes.

[0020] In one specific implementation, a reinforcing rib is provided between the support frame and the base plate, and the base plate has multiple holes.

[0021] Beneficial effects: This application provides a two-dimensional turntable. By setting a base plate, support frame, first driving component and outer frame, it can rotate to drive the internal second rotating component to rotate and adjust the angle. At the same time, the second driving component, inner frame and mounting plate can drive the angle sensor to be detected mounted on the mounting plate to rotate again, and the transmission direction is perpendicular to the direction of the outer frame. Thus, it can realize the synchronous rotation in two directions to reach the designed angle for angle sensor feedback angle error detection. It can also detect in each direction, thereby greatly improving the detection capability and detection efficiency. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0029] Please see Figures 1-4This application provides a two-dimensional turntable including a first rotating component 100 and a second rotating component 200.

[0030] Please see Figure 1 , 2 3. The first rotating assembly 100 includes a base plate 110, a support frame 120, a first driving component 130, and an outer frame 140. The support frame 120 is disposed on the top of the base plate 110. The first driving component 130 includes a housing 131, a rotating plate 132, and a servo motor 133. The housing 131 is fixedly connected to the top of a support frame 120. The rotating plate 132 is rotatably disposed inside the housing 131. The servo motor 133 is installed on the outside of the housing 131 and is drivenly connected to the rotating plate 132. One side of the outer frame 140 is fixedly connected to the rotating plate 132.

[0031] Among them, a bearing seat 150 is installed on the other side of the outer frame 140. The bearing seat 150 is set on the top of another support frame 120. By setting the bearing seat 150 on the first drive member 130 opposite to the first drive member 130, it is used to cooperate with the first drive member 130 to drive the outer frame 140 to rotate stably to the required angle.

[0032] Specifically, the side plate 141 has structural holes 1411. By opening structural holes 1411, it is convenient to strengthen the structural strength on the one hand, and to reduce the weight on the other hand.

[0033] In one specific implementation, a reinforcing rib 121 is provided between the support frame 120 and the base plate 110, and the base plate 110 has multiple holes.

[0034] Please see Figure 1 , 2 3 and 4, the second rotating assembly 200 includes a second driving member 210, an inner frame 220 and a mounting plate 230. The second driving member 210 is installed inside the outer frame 140. The inner frame 220 is rotatably disposed between the second driving member 210 and the outer frame 140. The first driving member 130 and the second driving member 210 are perpendicular to each other. The mounting plate 230 is installed inside the inner frame 220.

[0035] The servo motor 133 has a worm gear 1331 fixedly connected to its output end, and a worm wheel 1321 is fixedly sleeved on the rotating plate 132. The worm gear 1331 and the worm wheel 1321 mesh with each other. The second driving component 210 has the same structure as the first driving component 130. By setting the worm gear 1331 and the worm wheel 1321 to mesh, the servo motor 133 is started to drive the worm gear 1331 to rotate. The meshing of the worm gear 1331 drives the worm wheel 1321 to rotate, and the worm wheel 1321 drives the rotating plate 132 to rotate, thus realizing the transmission connection. The second driving component 210 has the same structural principle as the first driving component 130, so the specific structure of the second driving component 210 will not be described in detail.

[0036] Specifically, the outer frame 140 includes side panels 141 and connecting corner plates 142. The connecting corner plates 142 are fixedly connected between the two side panels 141. By setting the side panels 141 and connecting corner plates 142, the two side panels 141 connected in pairs form a frame, and the connecting corner plates 142 are used to connect the joints, thereby forming a stable frame structure.

[0037] In this embodiment, one side of the inner frame 220 is rotatably connected to the outer frame 140 via a connecting bearing 221 and is coaxial with the second driving member 210. By providing a structural hole 1411, the second driving member 210 can drive the inner frame 220 to rotate stably.

[0038] It should be noted that by setting the structural hole 1411, the second driving component 210 can drive the inner frame 220 to rotate stably. The through hole 231 is opened to allow the sensor parts of different models and sizes to be detected to pass through. Then the mounting surface is attached to the mounting plate 230, and then it is fixed with bolts through the mounting hole 232.

[0039] It should be noted that the specific detection method mainly involves setting the angle of the servo motor 133 driving its transmission, and then comparing the angle fed back by the sensor to compare the error between the two for detection. The motor control can be manually controlled or the controller can be set to start as needed. The power supply is also common knowledge in this field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0040] The working principle of this two-dimensional turntable is as follows: During use, the angle sensor or other sensor to be detected is mounted on the mounting plate 230. The through hole 231 on the mounting plate 230 allows the sensor's protruding part to pass through, ensuring stable installation. Then, the servo motor 133 is started to drive the worm gear 1331 to rotate. The worm gear 1331 meshes with and drives the worm wheel 1321 to rotate, which in turn drives the rotating plate 132 to rotate. The rotating plate 132 drives the outer frame 140 to rotate, which in turn drives the inner frame 220 to rotate. The inner frame 220 then drives the mounting plate 230 and the sensor to rotate in another direction. This allows for simultaneous rotation in two directions to achieve the designed angle for angle sensor feedback and angle error detection. Alternatively, detection can be performed in each direction individually, greatly improving detection capability and efficiency.

[0041] It should be noted that the specific model and specifications of the servo motor 133 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0042] The power supply and operating principle of the servo motor 133 are clear to those skilled in the art and will not be described in detail here.

[0043] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
