[0002] A high-speed precision turntable is a device used for high-precision rotational motion. By introducing a special servo system, it meets various parameter requirements, including angular range, angular acceleration, speed, positioning accuracy, and repeatability.

[0010] Preferably, the clamping mechanism includes a shell seat, two groups of extrusion cylinders are connected to one side of the inner wall of the shell seat, the output ends of the extrusion cylinders are connected to a push plate, the top of the push plate is connected to a clamping plate, the top of the shell seat is provided with a guide hole corresponding to the clamping plate, the turntable body is connected between the clamping plates, the bottom end of the shell seat is connected to a guide rod, and the bottom end of the guide rod is slidably connected to the base frame.

[0013] Preferably, an anti-slip pad is connected to one side of the connecting plate, and an anti-slip sleeve is sleeved on one side of the rotating frame.

[0014] Preferably, a detection method for a high-speed precision turntable detection device is characterized by comprising the following steps: S1. Use the laser light to project a beam onto the top of the clamping mechanism as a position mark. Place the turntable body to be inspected on the top of the clamping mechanism. Drive the extrusion cylinder to contract and drive the push plate to slide along the guide hole, thereby simply fixing the turntable body with the clamping plate. Then push the cylinder upward to lift the clamping mechanism, so that the turntable at the top of the turntable body passes through the through hole on the operating panel and is located on the inner side of the annular fixing platform. At the same time, the shell of the turntable body will abut against one side of the shock-absorbing rubber pad to keep the turntable body in a stable position. Then, the turntable body is connected to the external power supply. S2. Start the fixed cylinder to push the table edge detection mechanism, so that the rotating frame fits on the turntable surface through the anti-slip sleeve, rotate the rotating disk, and drive the screw through the meshing of the active bevel gear and each driven bevel gear, thereby driving the moving plate to move. Adjust the monitoring position of the laser displacement sensor on the turntable surface so that its monitoring point falls on the top of the turntable body, and start the turntable body to rotate. The elastic side plate has a certain elasticity. When the rotating turntable body is unstable, the rotating frame will shake. The laser ranging sensor will monitor the position relationship of the rotating frame in real time and detect the rotation stability of the turntable from the top and side surfaces of the turntable. S3, continue to extend the fixed cylinder to push the fixed arc plate, so that it fits tightly to the surface of the turntable through the anti-slip pad. Since the fixed cylinder is installed on one side of the extension frame, it is convenient to connect the extension frame to the turntable in disguise, and then energize the coil to make the magnetorheological fluid between the partition and the downward pressure annular frame become viscous, start the turntable rotation, and mobilize the downward pressure annular frame to rotate through the extension frame. When the downward pressure annular frame rotates, it can generate resistance through the setting of the magnetorheological fluid. The concentration of the magnetorheological fluid is controlled by input current to adjust the resistance value. The turntable state of the turntable under the condition of rotation resistance can be detected by the torque sensor and the laser displacement sensor. When performing the rotation stability test in S2, the connecting cylinder will push the downward pressure annular frame to move downward, and the limit rack between the downward pressure annular frame and the partition is used to limit the extension frame and the suspension mechanism to ensure the fixing effect. At the same time, the magnetic energy mechanism is connected to the current to generate a magnetic field to adsorb and fix the electromagnet ring to ensure the fixity of the suspension mechanism. S4. When performing this operation, the fixed cylinder pushes the table edge detection mechanism against the turntable surface in advance, and then the connected cylinder extends to push the downward pressure ring frame and squeeze it towards the magnetorheological fluid after the current is passed, so as to fix it. Then the superconductor in the magnetic energy mechanism is connected to the current. At the same time, the liquid nitrogen in the Dewar flask is pumped into the heat-insulating sealed box through the vacuum insulation hose, so that the superconductor is in a low-temperature environment, ensuring that the superconductor can generate a stable magnetic field. Then the direction of the incoming current of the electromagnet ring is changed to generate a repulsive force between the two, so that the suspension frame is suspended. At the same time, the side of magnet one and magnet two that are close to each other are the same pole, and also have a repulsive force, further ensuring the suspension effect of the suspension frame, driving the turntable, so that the turntable rotates with the extension frame and the suspension mechanism, simulating the working state of the turntable with the processed parts. Another method of inspection can be performed by installing a micrometer on the multi-purpose mounting frame and pressing it against the turntable surface; S5. During the detection, the sensors of each detection component can transmit the detected data to the controller 22, and the data can also be further transmitted to the background through the controller. During the operation detection, the door panel on one side of the frame 1 can be closed, and the fill light can be turned on for fill light to facilitate observation.

[0015] In summary, this application has the following beneficial technical effects: Through the mutual cooperation between the top surface testing mechanism and the table edge testing mechanism as well as the suspension mechanism and the magnetic energy mechanism inside the annular fixed table, the turntable can be subjected to resistance testing, top surface flatness testing, eccentricity testing and other tests in the same equipment. There is no need to transfer the turntable to different testing fixtures and equipment, which greatly reduces the consumption of human resources and effectively improves the inspection efficiency of the turntable. Through the setting of the clamping mechanism and the setting of the pushing cylinder, it can be applied to the fixation of various types of turntables. BRIEF DESCRIPTION OF THE DRAWINGS

An extension frame 12 is rotatably provided on the inner side of the connecting frame 71. The inner side is connected to a cylinder 13. The output end of the connecting cylinder 13 passes through the extension frame 12 and is connected to a downward pressure ring frame 14. A fixed cylinder 18 is connected to one side of the extension frame 12. The output end of the fixed cylinder 18 passes through the extension frame 12 and is connected to a table edge detection mechanism 19. A top surface testing mechanism 20 is connected to the top of the inner wall of the frame 1. A controller 22 is connected to one side of the frame 1. A through hole is opened at the top of the operating panel 2 corresponding to the turntable body 6, and a shock-absorbing rubber pad 25 is connected to the bottom end. Reference Figure 2 and Figure 3 As shown, the top of the inner wall of the frame 1 is located on both sides of the top surface test mechanism 20 and is connected with fill lights 21, which are set with LED lamps to fill light inside the equipment to facilitate penetration. Multi-purpose mounting brackets 23 are connected on both sides of the inner wall of the frame 1. Multiple mounting holes are opened on the surface of the mounting brackets 23 to ensure that they are suitable for the installation of auxiliary equipment (micrometers) of different sizes.

[0020] Reference Figure 4 As shown, the suspension mechanism includes a suspension frame 81 rotatably disposed within the annular fixing platform 7 and a second magnet 84 fixedly disposed on the top of the inner wall of the annular fixing platform 7. The bottom end of the suspension frame 81 is connected to an electromagnet ring 82, and the top ends of the suspension frame 81 are connected to two sides of a first magnet 83. The sides of the first magnet 83 and the second magnet 84 that are close to each other are arranged with the same poles, thereby achieving a repulsive effect and ensuring the subsequent suspension performance. A mounting groove is provided at the top of the suspension frame 81, and a coil 15 is connected to the bottom end of the inner side of the mounting groove, and a partition 16 is connected to the top surface of the coil 15. The downward-pressing annular frame 14 is located at the top of the mounting groove, and a limiting rack is connected to the side where the downward-pressing annular frame 14 and the partition 16 are close to each other, and magnetorheological fluid is filled between the two. One side of the coil 15 is connected to an external power supply, which generates current when powered on, so that the magnetorheological fluid filled inside has reduced fluidity and increased viscosity. The greater the current, the higher the viscosity. The magnetorheological fluid is separated by the partition 16, and the limiting rack is set on one side of the downward-pressing annular frame 14, which can effectively increase the friction between the magnetorheological fluid and the magnetorheological fluid during rotation. At the same time, as the downward movement of the downward-pressing annular frame 14 can play an effective limiting effect.

[0021] Reference Figure 6 As shown, the magnetic energy mechanism includes a heat-insulating sealed box 9 fixedly arranged at the bottom end of the inner portion of the annular fixed platform 7, a superconductor 10 is connected to the heat-insulating sealed box 9, and the heat-insulating sealed box 9 provides a relatively sealed environment for the superconductor 10, and has a heat-insulating effect. A vacuum insulation hose 11 is connected to one side of the heat-insulating sealed box 9, and a Dewar flask 17 is connected to the other side of the vacuum insulation hose 11. Liquid nitrogen is stored in the Dewar flask, and a valve 111 is connected to the end of the vacuum insulation hose 11 near the Dewar flask 17. A liquid nitrogen pump is connected to one side of the interior of the frame 1, and the end of the vacuum insulation hose 11 close to the Dewar flask 17 is connected to the liquid nitrogen pump, and the liquid inlet end of the liquid nitrogen pump is connected to the Dewar flask 17. It can be seen from the accompanying drawings that an air intake valve is connected to one side of the Dewar flask 17. Because it is a conventional setting, it is not described in detail in the specification and drawings. The liquid nitrogen pump draws out the liquid nitrogen in the Dewar flask 17 through the vacuum insulation hose 11 and discharges it into the insulated sealing box 9, providing a low-temperature environment for the superconductor 10, thereby maintaining the use effect of the superconductor 10.

[0022] Refer to the attached Figure 3 As shown, the clamping mechanism 5 includes a shell seat 51, and two groups of extrusion cylinders 52 are connected to one side of the inner wall of the shell seat 51. The output ends of the extrusion cylinders 52 are connected to a pushing plate 53, and the top of the pushing plate 53 is connected to a clamping plate 54. A guide hole is provided at the top of the shell seat 51 corresponding to the clamping plate 54, and the turntable body 6 is connected and set between the clamping plates 54. The bottom end of the shell seat 51 is connected and set with a guide rod 24, and the bottom end of the guide rod 24 is slidably connected to the base frame 3. It can be seen from the accompanying drawings that a plate for installing and fixing the extrusion cylinder 52 is connected inside the shell seat 51, and the shell seat 51 is fixed on one side of the plate, and the output end passes through the plate and is connected to the pushing plate 53. When the shell seat 51 extends or contracts, the clamping plate 54 can be driven to slide by the pushing plate 53. The above is a more common fixing mechanism, which is used in this application to clamp and fix the turntable body 6, and the two extrusion cylinders 52 are independently controlled.

[0023] Reference Figure 5As shown, the top surface testing mechanism 20 includes a mounting shell 201 fixedly arranged on the top of the inner wall of the frame 1, and three sets of screws 202 are rotatably arranged inside the mounting shell 201. The ends of the screws 202 close to each other are connected to driven bevel gears 203, and one end of the screws 202 is threadedly connected to a moving plate 204. One side of the moving plate 204 passes through the mounting shell 201 and is connected to a laser displacement sensor 205. The bottom end of the mounting shell 201 is rotatably provided with a rotating disk 206 through a circular axis, and the top end of the circular axis extends into the mounting shell 201 and is connected to a driving bevel gear 208. The driving bevel gear 208 is meshed with each driven bevel gear 203, and is manually rotated. The rotating disk 206 drives each screw 202 to rotate synchronously through the engagement between the active bevel gear 208 and the driven bevel gear 203, thereby adjusting the movable plate 204 to make synchronous displacement, driving the laser displacement sensor 205 below to move, which is suitable for turntable detection of different sizes. The bottom end of the rotating disk 206 is connected to a laser lamp 207. When the turntable body 6 is placed on the top circle of the clamping mechanism 5, the laser lamp 207 will project a light beam to hit the center position of the clamping mechanism 5. The center position can be quickly determined by the irradiation position of the light beam, so that it is easier to manually adjust when placing the turntable body 6, so that the turntable and the through hole on the operating plate 2 are further aligned.

[0024] Reference Figure 7As shown, the table edge detection mechanism 19 includes a fixed arc plate 191 fixedly arranged at the output end of the fixed cylinder 18, and a torque sensor 192 is connected to one side of the fixed arc plate 191, and a connecting plate 193 is connected to the other side of the torque sensor 192. When the connecting plate 193 is tightly attached to the turntable body 6 through the anti-slip pad 198 arranged on one side, when the turntable body 6 rotates, the torque sensor 192 can detect the torque between the connecting plate 193 and the fixed arc plate 191, and elastic side plates 194 are connected on both sides of the connecting plate 193. A rotating frame 195 is rotatably arranged on the side of the elastic side plates 194 that are away from each other, and high-precision bearings are connected to the corresponding rotating frames 195 on both sides of the elastic side plates 194 to facilitate the rotation of the rotating frame 195. Laser ranging sensors are connected to the corresponding rotating frames 195 on both sides of the fixed arc plate 191 Device 196. It can be seen from the attached drawings that the rotating frame 195 is set in an I-shape, and the anti-slip sleeve 197 is set on both ends of the rotating frame 195, which can increase the friction between the rotating frame 195 and the turntable body 6, so that the rotating frame 195 can rotate better, and at the same time play a protective effect. When the turntable body 6 rotates, once eccentricity or irregular shape occurs, it will squeeze the rotating frame 195 on one side, thereby causing the elastic side plate 194 to shake. The laser ranging sensor 196 detects the middle position of the rotating frame 195. In the absence of eccentricity or irregular shape, the monitoring data will not change. The elastic side plate 194 and the connecting plate 193 can be made of spring steel as a whole. It can be seen from the attached drawings that the adjacent edges of the connecting plate 193 and the elastic side plate 194 are provided with grooves to reduce the thickness and ensure elasticity.

[0025] A method for detecting a high-speed precision turntable detection device comprises the following steps: S1. Use the light beam projected by the laser lamp 207 on the top of the clamping mechanism 5 as a position mark, place the turntable body 6 to be inspected on the top of the clamping mechanism 5, drive the extrusion cylinder 52 to contract and drive the push plate 53 to slide along the guide hole, so that the turntable body 6 is simply fixed by the clamping plate 54, and then push the cylinder 4 to push the clamping mechanism 5 upward, so that the turntable at the top of the turntable body 6 passes through the through hole on the operating plate 2 and is located on the inner side of the annular fixing platform 7. At the same time, the shell of the turntable body 6 will abut against one side of the shock-absorbing rubber pad 25 to keep the turntable body 6 firmly positioned, and then the turntable body 6 is connected to the external power supply; S2. Start the fixed cylinder 18 to push the table edge detection mechanism 19, so that the rotating frame 195 is attached to the turntable surface through the anti-slip sleeve 197, and the rotating disk 206 is rotated. The active bevel gear 208 is engaged with each driven bevel gear 203 to drive the screw 202, thereby driving the movable plate 204 to move, and adjust the monitoring position of the laser displacement sensor 205 on the turntable surface so that its monitoring point falls on the top of the turntable body 6. The turntable body 6 is started to rotate. The elastic side plate 194 has a certain elasticity. When the rotating turntable body 6 is unstable, the rotating frame 195 will shake. The laser distance sensor 196 will monitor the position relationship of the rotating frame 195 in real time and detect the rotation stability of the turntable from the top and side surfaces of the turntable. S3, the fixed cylinder 18 continues to extend and push the fixed arc plate 191, so that it is tightly attached to the surface of the turntable through the anti-slip pad 198. Since the fixed cylinder 18 is installed on the side of the extension frame 12, it is convenient to connect the extension frame 12 to the turntable in disguise. Then, the coil 15 is energized to make the magnetorheological fluid between the partition 16 and the downward pressure ring frame 14 become viscous, and the turntable is started to rotate. The downward pressure ring frame 14 is mobilized to rotate through the extension frame 12. When the downward pressure ring frame 14 rotates, it can generate resistance through the setting of the magnetorheological fluid. By inputting current The concentration of the magnetorheological fluid is controlled to adjust the resistance value. The torque sensor 192 and the laser displacement sensor 205 can be used to detect the state of the turntable when it has rotational resistance. When performing the rotation stability test in S2, the connecting cylinder 13 pushes the downward pressure ring frame 14 to move downward. The limit rack between the downward pressure ring frame 14 and the partition 16 is used to limit the connection between the extension frame 12 and the suspension mechanism to ensure the fixing effect. At the same time, the magnetic energy mechanism is connected to the current to generate a magnetic field, which attracts and fixes the electromagnet ring 82, ensuring the fixity of the suspension mechanism. S4. When performing this operation, the fixed cylinder 18 is preliminarily used to push the table edge detection mechanism 19 against the turntable surface. The connecting cylinder 13 is then extended to push the downward pressing annular frame 14 and squeeze the magnetorheological fluid after the current is passed through it, thereby fixing it. Then, the superconductor 10 in the magnetic energy mechanism is connected to the current. At the same time, the liquid nitrogen in the Dewar flask 17 is pumped into the heat-insulating sealed box 9 through the vacuum insulation hose 11, so that the superconductor 10 is in a low-temperature environment, ensuring that the superconductor 10 can generate a stable magnetic field. Then, the direction of the current passed to the electromagnet ring 82 is changed to generate a repulsive force between the two, so that the suspension frame 81 is suspended. While suspended, the sides of magnet 1 83 and magnet 2 84 that are close to each other are of the same pole and also have a repulsive force, further ensuring the suspension effect of the suspension frame 81. The turntable is driven to rotate with the extension frame 12 and the suspension mechanism, simulating the working state of the turntable with the processed parts. Another method of turntable load inspection can be performed by installing a micrometer on the multi-purpose mounting frame 23 and pressing it against the turntable surface. S5. During the detection, the sensors of each detection component can transmit the detected data to the controller 22, and the data can also be further transmitted to the background through the controller 22. During the operation detection, the door panel on one side of the frame 1 can be closed, and the fill light 21 can be turned on for fill light to facilitate observation.

10. The detection method of the high-speed precision turntable detection device according to claim 9, characterized in that: The following steps are involved: S1. Use the beam of light projected by the laser lamp (207) on the top of the clamping mechanism (5) as a position mark, place the turntable body (6) to be tested on the top of the clamping mechanism (5), drive the extrusion cylinder (52) to contract and drive the push plate (53) to slide along the guide hole, so that the turntable body (6) is simply fixed by the clamping plate (54), and then push the cylinder (4) to lift the clamping mechanism (5) upward, so that the turntable at the top of the turntable body (6) passes through the through hole on the operating plate (2) and is located on the inner side of the annular fixing platform (7), and at the same time, the shell of the turntable body (6) will be against the side of the shock-absorbing rubber pad (25) to maintain the positioning and stability of the turntable body (6), and then the turntable body (6) is contacted with the external power supply; S2, start the fixed cylinder (18) to push the table edge detection mechanism (19), so that the rotating frame (195) is attached to the turntable surface through the anti-slip sleeve (197), rotate the rotating disk (206), and drive the screw (202) through the engagement of the active bevel gear (208) and each driven bevel gear (203), thereby driving the moving plate (204) to move, adjust the monitoring position of the laser displacement sensor (205) on the turntable surface, so that its monitoring point falls on the top of the turntable body (6), start the turntable body (6) to rotate, the elastic side plate (194) has a certain elasticity, and when the rotating turntable body (6) is unstable, the rotating frame (195) will shake, and the laser distance sensor (196) will monitor the position relationship of the rotating frame (195) in real time, and detect the rotation stability of the turntable from the top and side of the turntable; S3, the fixed cylinder (18) continues to extend and push the fixed arc plate (191), so that it is tightly attached to the turntable surface through the anti-slip pad (198). Since the fixed cylinder (18) is installed on one side of the extension frame (12), it is convenient to connect the extension frame (12) with the turntable in a disguised manner, and then energize the coil (15) to make the magnetorheological fluid between the partition (16) and the downward pressure ring frame (14) become viscous, start the turntable to rotate, and mobilize the downward pressure ring frame (14) to rotate through the extension frame (12). The downward pressure ring frame (14) can generate resistance through the setting of the magnetorheological fluid when rotating, and through The input current controls the concentration of the magnetorheological fluid, thereby adjusting the resistance value. The state of the turntable in the case of rotational resistance can be detected by the torque sensor (192) and the laser displacement sensor (205). When the rotation stability detection in S2 is performed, the connecting cylinder (13) pushes the downward pressing ring frame (14) to move downward, and the limit rack between the downward pressing ring frame (14) and the partition (16) is limited to connect the extension frame (12) and the suspension mechanism to ensure the fixing effect. At the same time, the magnetic energy mechanism is connected to the current to generate a magnetic field, which adsorbs and fixes the electromagnet ring (82) to ensure the fixity of the suspension mechanism. S4. When performing this operation, the fixed cylinder (18) is pre-set to push the table edge detection mechanism (19) against the turntable surface, and then the connecting cylinder (13) is extended to push the pressing ring frame (14) and squeeze the magnetorheological fluid after the current is passed, so as to fix it. Then the superconductor (10) in the magnetic energy mechanism is connected to the current, and at the same time, the liquid nitrogen in the Dewar flask (17) is pumped into the heat-insulating sealing box (9) through the vacuum insulation hose (11), so that the superconductor (10) is in a low temperature environment, ensuring that the superconductor (10) can generate a stable magnetic field, and then change The direction of the current input to the electromagnet ring (82) generates a repulsive force between the two, so that the suspension frame (81) is suspended. During the suspension, the sides of the magnets 1 (83) and 2 (84) that are close to each other are of the same pole and also have a repulsive force, further ensuring the suspension effect of the suspension frame (81). The turntable is driven to rotate with the extension frame (12) and the suspension mechanism, simulating the working state of the turntable with the processed parts. Another method of inspection can be performed by installing a micrometer on the multi-purpose mounting frame (23) and pressing it against the surface of the turntable. S5. During the detection, each detection component (sensor) can transmit the detected data to the controller (22), and the controller (22) can further transmit the data to the background. During the operation detection, the door panel on one side of the frame (1) can be closed, and the fill light (21) can be turned on for fill light to facilitate observation.
