[0001] The invention relates to the technical field of gyroscope accelerometer automatic testing, in particular to a gyroscope accelerometer automatic testing device. Background Art

[0002] Gyroscope and accelerometer test equipment is a key tool to ensure the performance and quality of gyroscopes and accelerometers, and is widely used in aerospace, automotive manufacturing, consumer electronics and other fields. With the continuous development of science and technology, gyroscope and accelerometer test equipment is also constantly updated and developed in the direction of more intelligence, automation and high precision. These devices can simulate various working environments of gyroscopes and accelerometers in actual applications, and perform comprehensive and accurate tests on them.

[0003] Before testing the gyroscope and accelerometer, the horizontality of the test platform needs to be calibrated to prevent errors in the test results caused by the deflection of the test platform. Most existing calibration methods use manual calibration, which has a low level of automation. After calibration, the horizontality of the test platform cannot be dynamically detected during the test process, and there is also a lack of effective means to lock the calibrated test platform to reduce the frequency of leveling. Summary of the invention

[0004] The object of the present invention is to provide a gyroscope accelerometer automatic testing device to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a gyroscope accelerometer automatic testing equipment, comprising a test chassis, a test platform installed in the test chassis, a mechanical arm provided in the test chassis, a transmission component provided in the test chassis, and a monitoring component provided in the test chassis; the test platform comprises a rotating base, the rotating base is installed in the test chassis, a pre-inspection component is installed on the rotating base, an automatic calibration component is rotatably installed on the rotating base, and a test turntable is installed on the automatic calibration component.

[0006] The test equipment is equipped with a control system, which is used to control the operation of the entire equipment. The monitoring component is used to monitor the posture and various parameters of the equipment under test during the test process; the transmission component is used to transport the equipment under test to the test platform; the robotic arm is used to install the equipment under test on the test platform, or disassemble the equipment after the test and place it on the transmission component.

[0007] During operation, the control system controls the transmission component to transport the device to be tested to the test platform, and the device to be tested is in place. The mechanical arm installs the in-place device to the test platform.

[0008] Furthermore, the rotating base includes a base shell, which is installed in the test chassis, a rotating column is rotatably installed on the base shell, a driving motor is installed in the base shell, a driving gear is installed on the output shaft of the driving motor, a belt is provided between the driving gear and the rotating column, the driving gear and the transmission column are connected by belt drive, an automatic calibration component is installed on the top of the rotating column, the automatic calibration component is rotatably connected to the base shell, and a pre-inspection component is installed on the top of the base shell.

[0009] Furthermore, the pre-inspection component includes an annular lifting platform, on which a plurality of test components are installed, and the annular lifting platform is installed on the top of the base shell.

[0010] The annular lifting platform is used to drive the test component to rise or fall; the annular lifting platform is located outside the automatic calibration component, and the annular lifting platform does not contact the automatic calibration component.

[0011] Furthermore, the test assembly includes a test frame, which is installed on a circular lifting platform. A test lever is rotatably installed on the test frame, a test ball is rotatably installed on one end of the test lever, an iron core rod is installed on the other end of the test lever, a reset spring is installed between the test lever and the test frame, an induction coil is installed in the test frame, and one end of the test lever on which the iron core rod is installed is longer than the end on which the test ball is installed.

[0012] The induction coil includes the primary coil and the secondary coil. When the induction coil is energized, it generates a magnetic field. When the core rod moves in the induction coil, the magnetic field distribution is changed, causing the induced voltage in the secondary coil to change. The control system determines the displacement of the core rod by analyzing the voltage change. By comparing the displacement of several groups of core rods, it analyzes whether the top tray is in a horizontal state.

[0013] The control system starts the circular lifting platform, which drives the test assembly to descend, so that the test ball on the test assembly is close to the top tray, and the drive motor is turned on. The output shaft of the drive motor drives the rotating column to rotate through the driving gear and belt, and the rotating column drives the automatic calibration assembly to rotate. The top tray on the automatic calibration assembly drives the test slope to rotate, so that the test slope rotates over the test ball. When the test slope rotates, it gradually drives the test ball to move upward. The test ball drives one end of the test lever to lift, and the test lever rotates on the test chassis. Since the end of the test lever on which the iron core rod is installed is longer than the end on which the test ball is installed, according to the lever principle, the test lever amplifies the displacement of the test ball through the iron core rod end, and the iron core rod passes through the induction coil. The control system determines the horizontal state of the top tray by analyzing the change in the induced voltage in the secondary coil. If the top tray is in a horizontal state, the difference in the change in the induced voltage of several groups is similar and is within the standard error range, and the displacement between several iron core rods is similar. If the top tray is in a non-horizontal state, the difference in the change in the induced voltage of several groups is large and exceeds the standard error range.

[0014] Furthermore, the automatic calibration component includes a bottom tray and a top tray. The bottom tray is installed on the top of the rotating column. A connecting column is installed on the bottom tray. A connecting cap is installed on the bottom end of the top tray. The connecting cap is movably connected to the connecting column. A plurality of test slopes are provided on the top tray.

[0015] The connecting column and the connecting cap cooperate with each other to form a universal joint structure, so that the bottom tray can support the top tray and ensure that the top tray can be freely leveled.

[0016] Furthermore, the automatic calibration component also includes a plurality of sliding columns, a plurality of locking components and a plurality of adjusting motors. The sliding columns are mounted on the bottom tray, which are slidably connected to the top tray. A lifting cylinder is slidably mounted on the sliding columns, and an adjusting gear cylinder is threadedly connected to the lifting cylinder. The adjusting gear cylinder is rotatably mounted on the bottom tray. The adjusting motor is mounted in the bottom tray, and an adjusting gear is mounted on the output shaft of the adjusting motor. The adjusting gear is meshed with the adjusting gear cylinder for transmission. The locking component is mounted on the top tray, and a test turntable is mounted on the top tray. The position of the test slope corresponds to the position of the lifting cylinder.

[0017] When the top tray is not in a horizontal state, the control system turns on the adjustment motor, and the output shaft of the adjustment motor drives the adjustment gear to rotate, and the adjustment gear drives the adjustment gear cylinder to rotate, and the adjustment gear cylinder rotates on the bottom tray and drives the lifting cylinder to slide along the sliding column through the thread, and the lifting cylinder drives the top tray to slide. According to the detection results, the control system makes the lifting cylinder at the position where the core rod displacement is larger drive the top tray down, and makes the lifting cylinder at the position where the core rod displacement is smaller drive the top tray up, and several lifting cylinders drive the top tray to move up and down in all directions for adjustment. After the adjustment is completed, repeat the previous operation, and use the pre-inspection component to detect the horizontality of the top tray again, and repeat this cycle until the top tray is in a horizontal state.

[0018] Furthermore, the locking assembly includes an inflatable shell, which is installed on the top tray, and a telescopic cap is slidably installed in the inflatable shell, a locking rod is installed on the telescopic cap, the locking rod is slidably connected to the top tray, the locking rod passes through the top tray and is installed with a locking ring, a plurality of L-shaped locking parts are rotatably installed on the locking ring, a locking spring is installed between the L-shaped locking parts and the locking ring, an inflatable chamber is formed between the telescopic cap and the inflatable shell, the inflatable chambers are connected by a three-way pipe, and the three-way pipe is connected to the inflatable device.

[0019] The charging device is used to charge the three-way pipe with gas.

[0020] Furthermore, a first locking plate is provided on the L-shaped locking member, and a second locking plate is provided on the L-shaped locking member. Both the first locking plate and the second locking plate are made of a material with a high friction coefficient.

[0021] After the top tray is leveled, the control system uses the inflation device to fill gas into the three-way pipe. The gas enters the inflation chamber from the three-way pipe, the pressure in the inflation chamber increases, and the telescopic cap drives the locking rod to slide upward under the action of pressure, and the locking rod drives the locking ring to slide upward. The L-shaped locking piece on the locking ring contacts the surface of the lifting drum, and the first locking plate contacts the lifting drum first, and then driven by the locking ring, the L-shaped locking piece rotates on the locking ring until the second locking plate contacts the lifting drum. The first locking plate and the second locking plate cooperate to lock the lifting drum to prevent the lifting drum from deflecting and keep the top tray in a horizontal state.

[0022] Furthermore, the test turntable includes a rotating bracket, which is installed on the top support box, on which a test disc is rotatably installed, and on which a flip motor is installed, and an output shaft of the flip motor passes through the rotating bracket and is connected to the test disc.

[0023] After the lifting drum is locked, the control system starts the flip motor and the drive motor. The output shaft of the flip motor drives the test disc to rotate. The drive motor drives the entire test turntable to rotate through the automatic calibration component, thereby realizing multi-angle flipping of the device under test. The monitoring component monitors the posture and various parameters of the device under test. During the test, when the test equipment on the test disc flips, the inertial force generated is transmitted to the top tray through the test turntable, causing the top tray to shift. The control system starts the pre-inspection component to perform dynamic spot checks on the horizontality of the top tray. When the top tray has deviations in horizontality, the automatic calibration component is used in time to perform leveling and deviation correction to ensure that the top tray is always in a horizontal state during the entire test process. When the test is completed, the robotic arm disassembles the tested equipment and places it on the transmission component. The transmission component transmits the tested equipment out, thereby realizing the test of the device under test.

[0024] Furthermore, the sliding column is provided with a vertical groove, and the lifting drum is provided with a convex block, which is engaged with the groove. The groove and the convex block are engaged, so that the lifting drum can only slide up and down along the sliding column and cannot rotate relatively.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. Use the flip motor to drive the test plate to rotate, and use the drive motor to drive the entire test turntable to rotate, so as to achieve the purpose of multi-angle flipping of the device under test.

When the top tray levelness deviates, the automatic calibration component is used to level and correct it in time to ensure that the top tray is always in a horizontal state during the entire test process, thereby improving the accuracy of the test.

[0027] 2. Use the detection slope to drive the test ball upward, the test ball drives one end of the test lever to lift, and the test lever drives the iron core rod at the other end to pass through the induction coil. The control system determines the displacement of the iron core rod by analyzing the magnitude of the voltage change, and achieves the purpose of top tray horizontality detection by comparing the displacement of several groups of iron core rods. The test lever amplifies the displacement of the test ball through the end of the iron core rod, so that the displacement of the iron core rod increases, making the detection more accurate.

[0028] 3.

[0049] The automatic calibration component 23 also includes a plurality of sliding columns 237, a plurality of locking components 238 and a plurality of adjusting motors 235. The sliding columns 237 are mounted on the bottom tray 232. The sliding columns 237 are slidably connected to the top tray 231. A lifting cylinder 234 is slidably mounted on the sliding columns 237.

[0050] The locking assembly 238 includes an inflatable housing 2383, which is mounted on the top tray 231. A telescopic cap 2382 is slidably mounted in the inflatable housing 2383, a locking rod 2381 is mounted on the telescopic cap 2382, the locking rod 2381 is slidably connected to the top tray 231, the locking rod 2381 penetrates the top tray 231 and is mounted with a locking ring 2385, a plurality of L-shaped locking pieces 2386 are rotatably mounted on the locking ring 2385, a locking spring 2387 is mounted between the L-shaped locking piece 2386 and the locking ring 2385, an inflatable chamber 2384 is formed between the telescopic cap 2382 and the inflatable housing 2383, the inflatable chamber 2384 is connected through a three-way pipe 239, and the three-way pipe 239 is connected with an inflating device. The inflating device is used to fill the three-way pipe 239 with gas.

[0051] A first locking plate 2388 is provided on the L-shaped locking member 2386 , and a second locking plate 2389 is provided on the L-shaped locking member 2386 . Both the first locking plate 2388 and the second locking plate 2389 are made of a material with a high friction coefficient.

[0052] The test turntable 24 includes a rotating bracket 241 , which is mounted on the top support box. A test disc 242 is rotatably mounted on the rotating bracket 241 . A flip motor 243 is mounted on the rotating bracket 241 . The output shaft of the flip motor 243 passes through the rotating bracket 241 and is connected to the test disc 242 .

[0053] The sliding column 237 is provided with a vertical groove, and the lifting drum 234 is provided with a projection, which is engaged with the groove. The groove and the projection are engaged, so that the lifting drum 234 can only slide up and down along the sliding column 237 and cannot rotate relatively.

[0054] The working principle of the present invention is as follows: during operation, the control system controls the transmission component to transport the device to be tested to the position of the test platform 2, and the device to be tested is in place. The mechanical arm installs the in-place device to be tested to the test platform 2.

[0055] The control system starts the annular lifting platform 221, and the annular lifting platform 221 drives the test component 222 to descend, so that the test ball 2222 on the test component 222 is close to the top tray 231, and the driving motor 212 is turned on. The output shaft of the driving motor 212 drives the rotating column 213 to rotate through the driving gear and the belt, and the rotating column 213 drives the automatic calibration component 23 to rotate. The top tray 231 on the automatic calibration component 23 drives the test slope 2311 to rotate, so that the test slope 2311 rotates over the test ball 2222. When the test slope 2311 rotates, it gradually drives the test ball 2222 to move upward, and the test ball 2222 drives one end of the test lever 2221 to lift up, and the test lever 2221 is on the test chassis 2223 The test lever 2221 rotates upward, because one end of the iron core rod 2225 installed is longer than the end of the test ball 2222, according to the lever principle, the test lever 2221 amplifies the displacement of the test ball 2222 through the iron core rod 2225 end, and the iron core rod 2225 passes through the induction coil 2224. The control system determines the horizontal state of the top tray 231 by analyzing the change of the induced voltage in the secondary coil. If the top tray 231 is in a horizontal state, the differences between several groups of induced voltage changes are similar and are within the standard error range, and the displacements between several iron core rods 2225 are similar. If the top tray 231 is in a non-horizontal state, the differences between several groups of induced voltage changes are large and exceed the standard error range.

[0056] When the top tray 231 is in a non-horizontal state, the control system turns on the adjustment motor 235, the output shaft of the adjustment motor 235 drives the adjustment gear 236 to rotate, the adjustment gear 236 drives the adjustment gear cylinder 233 to rotate, the adjustment gear cylinder 233 rotates on the bottom tray 232 and drives the lifting cylinder to slide along the sliding column 237 through the thread, and the lifting cylinder 234 drives the top tray 231 to slide. According to the detection result, the control system makes the lifting cylinder 234 at the position where the displacement of the core rod 2225 is larger drive the top tray 231 to descend, and makes the lifting cylinder 234 at the position where the displacement of the core rod 2225 is smaller drive the top tray 231 to rise, and several lifting cylinders 234 drive the top tray 231 to move up and down in all directions. After the adjustment is completed, repeat the previous operation, and use the pre-inspection component 22 to detect the horizontality of the top tray 231 again, and repeat this cycle until the top tray 231 is in a horizontal state.

[0057] After the top tray 231 is leveled, the control system uses the inflation device to fill gas into the three-way pipe 239, and the gas enters the inflation chamber 2384 from the three-way pipe 239. The pressure in the inflation chamber 2384 increases, and the telescopic cap 2382 drives the locking rod 2381 to slide upward under the action of pressure, and the locking rod 2381 drives the locking ring 2385 to slide upward, and the L-shaped locking piece 2386 on the locking ring 2385 contacts the surface of the lifting drum 234, and the first locking plate 2388 first contacts the lifting drum 234, and then, driven by the locking ring 2385, the L-shaped locking piece 2386 rotates on the locking ring 2385 until the second locking plate 2389 contacts the lifting drum 234, and the first locking plate 2388 and the second locking plate 2389 cooperate to lock the lifting drum 234 to prevent the lifting drum 234 from deflecting, so that the top tray 231 remains in a horizontal state.

[0058] After the lifting drum 234 is locked, the control system turns on the flipping motor 243 and the driving motor 212. The output shaft of the flipping motor 243 drives the test disc 242 to rotate. The driving motor 212 drives the entire test turntable 24 to rotate through the automatic calibration component 23, thereby realizing the multi-angle flipping of the device to be tested. The monitoring component monitors the posture and various parameters of the device to be tested. During the test process, when the test device on the test disc 242 flips, the inertial force generated is transmitted to the top tray 231 through the test turntable 24, which will cause the top tray 231 to deviate. The control system starts the pre-inspection component 22 to perform dynamic spot checks on the horizontality of the top tray 231. When the horizontality of the top tray 231 deviates, the automatic calibration component 23 is used in time to level and correct the deviation, ensuring that the top tray 231 is always in a horizontal state during the entire test process. When the test is completed, the robot arm disassembles the tested equipment and places it on the transmission component.
