Description

Technical Field

[0001] This invention relates to the field of double gear ring technology, and in particular to an integrated cleaning and testing system for double internal gear rings. Background Technology

[0002] A double internal gear ring is a structure with two internal gear rings mounted on the same base. It is widely used in heavy-load rotating equipment such as slewing bearings, planetary gear reducers, and yaw / pitch systems for wind turbines. The two internal gear rings mesh with different planetary gear sets. The phase consistency and coaxiality between the two gear rings directly affect the vibration, noise, and load distribution uniformity of the transmission system. Therefore, strict testing requirements are placed on the phase consistency, coaxiality, radial runout, and end-face flatness of the double internal gear ring.

[0003] Existing detection technologies have the following shortcomings: I. In the existing testing process, gear ring cleaning and testing are two independent procedures that need to be completed on different equipment. During the process of transferring the workpiece to the testing equipment after cleaning, dust, oil and other contaminants may re-adhere to the surface, affecting the measurement accuracy.

[0004] Second, existing testing methods, such as gear measuring centers and coordinate measuring machines, require each of the two internal gear rings to be tested for various parameters one by one. It is impossible to obtain multiple test data such as flatness, radial runout, phase difference and coaxiality of the two gear rings in one clamping, resulting in low testing efficiency and easy to introduce positioning errors by multiple clamping.

[0005] Third, the phase consistency and coaxiality of the two internal gear rings are the core quality indicators that distinguish double gear rings from single gear rings. Although existing coordinate measuring machines can indirectly obtain these related parameters through post-processing data calculation, the process is cumbersome and the accuracy is limited.

[0006] Fourth, relying on coordinate measuring machines or gear measuring centers for offline inspection results in a single-piece inspection time of 30-60 minutes, which cannot meet the online inspection needs of large-scale production lines. Summary of the Invention

[0007] The present invention aims to solve the above-mentioned defects and provide an integrated cleaning and inspection system for dual internal gear rings.

[0008] To overcome the shortcomings of the prior art, the technical solution adopted by the present invention to solve its technical problem is: an integrated system for cleaning and detecting dual internal gear rings, comprising: The main housing has an open structure at its upper end, and a movable carrier is horizontally slidably mounted on the upper end along the axial direction of the opening. The movable carrier has a detection cavity, and the movable carrier is equipped with an inner cavity rinsing and drying mechanism for rinsing and drying the inner cavity of the double gear ring to be tested. Inside the movable carrier is a carrier lifting and rotating mechanism for positioning, lifting and lowering, and rotating the double gear ring to be tested. The carrier lifting and rotating mechanism is located directly below the movement trajectory of the movable carrier. A horizontal movement drive mechanism is installed on the main housing and is used to drive the moving carrier to slide horizontally on the main housing along the axial direction of the opening of the main housing. An outer circular spraying mechanism is installed on the main housing and is used to recover the cleaning liquid inside the main housing and to rinse and spray the outer periphery of the double gear ring to be tested located in the first position. The elastic pressing and flatness measuring mechanism is set on the movable carrier and located in the detection cavity. It is used to detect the flatness of the double gear ring to be tested in the second position and to continuously elastically press the double gear ring to be tested during the process of moving from the second position to the fourth position. The radial runout detection mechanism is mounted on a moving carrier and is used to detect the radial runout of the outer circumference of the double gear ring under test when it is in the third position and in a rotating state. The coaxiality visual inspection mechanism is mounted on a movable carrier and located at the top of the inspection cavity. It is used to inspect the coaxiality of the two internal teeth of the double gear ring under test. The meshing phase detection mechanism is mounted on a moving carrier and is used to detect the meshing phase difference between the two internal teeth of the double gear ring under test when it is in the fourth position during rotation. This system performs cleaning and testing modes on the double gear ring under test. Cleaning mode: When the double gear ring to be tested is in the first position, the moving carrier moves to the position where the inner cavity rinsing and drying mechanism is directly above the carrier lifting and rotating mechanism. The carrier lifting and rotating mechanism drives the double gear ring to be tested to rotate. The inner cavity rinsing and drying mechanism rinses and dries the inner cavity of the double gear ring to be tested. The outer circle circulating spray mechanism sprays and rinses the outer circumference of the double gear ring to be tested. Detection mode: The moving carrier moves to the position where the detection chamber is directly above the carrier lifting and rotating mechanism. The carrier lifting and rotating mechanism lifts the double gear ring to be tested from the first position to the second position. The elastic pressing and flattening mechanism detects the flatness of the upper surface of the double gear ring to be tested. The double gear ring under test is lifted from the second position to the third position. The bearing lifting and rotating mechanism drives the double gear ring under test to rotate. The radial runout detection mechanism detects the radial runout of the outer circumference of the double gear ring under test when it is rotating. The double gear ring under test is lifted from the third position to the fourth position. The bearing lifting and rotating mechanism drives the double gear ring under test to rotate. The meshing phase detection mechanism detects the phase difference when the two internal teeth of the double gear ring under test rotate.

[0009] In a further improvement, the outer circular circulating spray mechanism includes a recovery water tank, a circulating pump, and water nozzles; the recovery water tank is connected to the lower end of the main body, and the outlet of the recovery water tank is connected in series with the circulating pump and the water nozzles through a pipeline assembly; the water nozzles are detachably installed at a preset mounting position on the main body.

[0010] In a further improvement, the inner cavity rinsing and drying mechanism includes a cleaning outer cylinder, a lifting cylinder, and a telescopic spray column; the cleaning outer cylinder is mounted on a movable carrier, the telescopic spray column is located inside the cleaning outer cylinder, and the telescopic spray column is a hollow columnar structure with an internal fluid channel; the lifting cylinder is located at the upper end of the cleaning outer cylinder, and the output end of the lifting cylinder is connected to the upper end of the telescopic spray column; multiple pressurized nozzles are radially arranged in a preset area at the lower end of the telescopic spray column, and a preset connection position on the telescopic spray column is connected to an external fluid supply mechanism through a pipeline assembly.

[0011] In a further improvement, the load-bearing lifting and rotating mechanism includes a lifting rotating platform and a positioning load-bearing cylinder; the positioning load-bearing cylinder is coaxially disposed on the top of the lifting rotating platform; and a water guide window is provided circumferentially on the positioning load-bearing cylinder.

[0012] In a further improvement, the elastic pressure-holding and leveling mechanism includes guide posts, a pressure-holding moving plate, a leveling rotating ring, and a pressure spring; at least four guide posts are provided, all vertically arranged inside the detection cavity, and each guide post passes through the pressure-holding moving plate to guide the pressure-holding moving plate to move up and down in the vertical direction; the leveling rotating ring is rotatably arranged in the central through hole of the pressure-holding moving plate; at least four probe leveling units are arranged circumferentially on the leveling rotating ring; the pressure spring is sleeved on the guide posts, with its upper end abutting against the inner wall of the detection cavity and its lower end abutting against the pressure-holding moving plate.

[0013] In a further improvement, the probe leveling unit includes a probe base, a piston block, a holding spring, and a displacement sensor; the probe base has a central hole along the axial direction and a movable cavity coaxially connected to the central hole; the piston block is slidably disposed in the movable cavity, and the lower end of the piston block is connected to a leveling contact pin; the holding spring is disposed in the movable cavity and is used to push the piston block to extend the leveling contact pin outward through the central hole to the outside; the displacement sensor is coaxially disposed on the upper end of the probe base, and the detection end of the displacement sensor is connected to the upper end of the piston block.

[0014] In a further improvement, the meshing phase detection mechanism includes two phase difference detection units, which are used to detect the rotation angle of the two internal teeth of the double gear ring under test.

[0015] In a further improvement, the phase difference detection unit includes a lateral feed driver, a probe slide, a rotating shaft, and an angle adjustment motor; the probe slide is horizontally slidably mounted on a movable support, and the output end of the lateral feed driver is connected to the probe slide; the upper end of the rotating shaft is coaxially connected to the probe slide, and the lower end of the rotating shaft extends downward into the detection chamber through a preset window on the movable support and is coaxially connected to a phase measuring gear; the angle adjustment motor is mounted on the probe slide and coaxially connected to the rotating shaft; the angle encoder is mounted on the angle adjustment motor.

[0016] The beneficial effects of this invention are as follows: This invention achieves switching between the cleaning and testing stations through the horizontal sliding of the moving carrier. The double gear ring under test can be cleaned and tested in a single clamping, avoiding secondary contamination during transport caused by separating the cleaning and testing processes, thus ensuring testing accuracy. It integrates flatness testing, radial runout testing, meshing phase testing, and coaxiality testing into one unit, acquiring multiple parameters simultaneously in a single clamping, solving the problem of low efficiency in existing technologies that require testing one ring at a time. The elastic holding and flatness measuring mechanism has dual functions of flatness testing and continuous elastic holding, verifying the gear ring's positioning status and providing stable elastic holding throughout the testing process, preventing rotation. Anomalies during detection affect the results; the rotating ring for measuring flatness rotates synchronously with the gear ring and also provides auxiliary shielding for coaxiality visual inspection, reducing reflection interference and enabling accurate acquisition of the center deviation of the two internal teeth for direct measurement of coaxiality; the phase-measuring meshing gears of each phase difference detection unit mesh with the two stages of internal teeth of the double gear ring, and directly measure the phase consistency error of the two stages of internal teeth in conjunction with the angle encoder, solving the problem of lack of dedicated detection methods for associated parameters; the coaxiality visual inspection mechanism is reused in the phase detection process to monitor the rotation angle of the phase-measuring meshing gears, assisting in confirming the meshing state, realizing the linkage of detection functions, and improving the reliability of detection.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 A dual-unit internal gear ring cleaning and inspection integrated system, comprising: The main housing 1 has an open structure at its upper end, forming a working space for accommodating cleaning fluid and cleaning operations. A movable carrier 3 is horizontally slidable along the axial direction of the opening at its upper end. The movable carrier 3 has a detection chamber 301 and is equipped with an inner cavity rinsing and drying mechanism 2 for rinsing and drying the inner cavity of the double gear ring to be tested. Inside the movable carrier 3 is a carrier lifting and rotating mechanism 10 for positioning, lifting, moving up and down, and rotating the double gear ring to be tested. The carrier lifting and rotating mechanism 10 is located directly below the movement trajectory of the movable carrier 3, so that after the movable carrier 3 moves horizontally, the inner cavity rinsing and drying mechanism 2 and the detection chamber 301 can be moved directly above the carrier lifting and rotating mechanism 10. The carrier lifting and rotating mechanism 10 can lift and move the double gear ring to be tested into the internal space of the detection chamber 301 for multiple tests. The horizontal movement drive mechanism 4 is installed on the main housing 1 and is used to drive the mobile carrier 3 to slide horizontally on the main housing 1 along the axial direction of the opening of the main housing 1, so as to realize the switching between cleaning mode and detection mode. The outer circular spraying mechanism 5 is installed on the main housing 1 and is used to recover the cleaning liquid in the main housing 1 and to rinse and spray the outer periphery of the double gear ring to be tested located in the first position to improve the cleaning efficiency. The elastic pressing and flatness measuring mechanism 6 is disposed on the movable carrier 3 and located in the detection cavity 301. It is used to detect the flatness of the double gear ring to be tested in the second position and to continuously elastically press the double gear ring to be tested during the process of moving from the second position to the fourth position. The radial runout detection mechanism 7 is mounted on the movable support body 3 and is used to detect the radial runout of the outer circumference of the double gear ring under test when it is in the third position and in a rotating state. The coaxiality visual inspection mechanism 9 is set on the movable carrier 3 and located at the top of the inspection cavity 301. It is used to detect the coaxiality of the two internal teeth of the double gear ring under test by visual imaging. The meshing phase detection mechanism 8 is mounted on the movable carrier 3 and is used to detect the meshing phase difference between the two internal teeth of the double gear ring under test when it is in the fourth position and rotating. This system performs cleaning and testing modes on the double gear ring under test. Cleaning mode: When the double gear ring to be tested is in the first position, the moving carrier 3 moves to the position where the inner cavity flushing and drying mechanism 2 is directly above the carrier lifting and rotating mechanism 10. The carrier lifting and rotating mechanism 10 drives the double gear ring to be tested to rotate. The inner cavity flushing and drying mechanism 2 flushes and dries the inner cavity of the double gear ring to be tested. The outer circle circulating spraying mechanism 5 sprays and washes the outer circumference of the double gear ring to be tested to remove oil stains and processing debris from the double gear ring. Detection mode: The movable carrier 3 moves to the position where the detection cavity 301 is directly above the carrier lifting and rotating mechanism 10. The carrier lifting and rotating mechanism 10 lifts the double gear ring to be tested from the first position to the second position. The elastic pressing and flattening mechanism 6 detects the flatness of the upper surface of the double gear ring to be tested in order to determine whether the double gear ring to be tested is accurately positioned and supported on the carrier lifting and rotating mechanism 10. The double gear ring to be tested is lifted from the second position to the third position. The elastic pressing and flattening mechanism 6 continuously presses the double gear ring to be tested against the bearing lifting and rotating mechanism 10 to adjust and maintain the flatness of the double gear ring to be tested. The bearing lifting and rotating mechanism 10 drives the double gear ring to be tested to rotate. The radial runout detection mechanism 7 detects the radial runout of the outer circumference of the double gear ring to be tested when it is rotating. The double gear ring under test is lifted from the third position to the fourth position. The bearing lifting and rotating mechanism 10 drives the double gear ring under test to rotate. The meshing phase detection mechanism 8 detects the phase difference when the two internal teeth of the double gear ring under test rotate.

[0021] This solution avoids secondary contamination of the workpiece during transportation and affects measurement accuracy by cleaning the double gear ring before inspection. The cleaning and inspection processes are completed in one clamping, and the phase consistency error and coaxiality error between the two internal gear ring segments can be directly measured.

[0022] In another embodiment, two internal cavity rinsing and drying mechanisms 2 can be integrated on the movable carrier 3, and two carrier lifting and rotating mechanisms 10 and two sets of external circular spraying mechanisms 5 are set inside the main housing 1. The detection chamber 301 is located between the two internal cavity rinsing and drying mechanisms 2. By moving the movable carrier 3, the opening at the upper end of the main housing 1 is opened, and the double gear rings to be tested can be placed on the carrier lifting and rotating mechanisms 10 respectively. See Figure 5 After completion, the two inner cavity rinsing and drying mechanisms 2 simultaneously clean the gear rings positioned on the two bearing lifting and rotating mechanisms 10. Then, the moving bearing 3 moves so that the detection chamber 301 is aligned with the two bearing lifting and rotating mechanisms 10 in turn, thereby detecting the double gear ring to be tested. This method can greatly improve the detection speed and increase efficiency.

[0023] In a specific embodiment, the outer circular circulating spray mechanism 5 includes a recovery water tank 503, a circulating pump 502, and a water nozzle 501. The recovery water tank 503 is connected to the lower end of the main tank 1 and is used to receive and collect the cleaning liquid collected in the main tank 1 after rinsing. The outlet of the recovery water tank 503 is connected in series with the circulating pump 502 and the water nozzle 501 through a pipeline assembly. The water nozzle 501 is detachably installed at a preset mounting position on the main tank 1 and is used to spray and rinse the outer circumference of the double gear ring to be tested located at the first position. The circulating pump 502 is used to pressurize and transport the cleaning liquid in the recovery water tank 503 to the water nozzle 501 to form a circulating rinsing circuit. After the water nozzle 501 is removed, it is also convenient to drain the recovery water tank 503 periodically.

[0024] In a specific embodiment, the inner cavity rinsing and drying mechanism 2 includes a cleaning outer cylinder 201, a lifting cylinder 202, and a telescopic spray column 203. The cleaning outer cylinder 201 is mounted on a movable carrier 3. The telescopic spray column 203 is located inside the cleaning outer cylinder 201 and is a hollow columnar structure with an internal fluid channel. The lifting cylinder 202 is located at the upper end of the cleaning outer cylinder 201, and its output end is connected to the upper end of the telescopic spray column 203 to drive the telescopic spray column 203 to move axially within the cleaning outer cylinder 201. A plurality of pressurized nozzles 204 are radially arranged in a preset area at the lower end of the telescopic spray column 203. A preset connection position on the telescopic spray column 203 is connected to an external fluid supply mechanism through a pipeline assembly. The fluid supply mechanism is used to provide cleaning liquid and drying airflow to the telescopic spray column 203 respectively.

[0025] When the double gear ring under test is in the first position, the external fluid supply mechanism supplies cleaning fluid to the telescopic spray column 203. The lifting cylinder 202 drives the telescopic spray column 203 to move down and penetrate into the inner cavity of the double gear ring under test. The pressurized nozzle 204 sprays cleaning fluid to rinse the inner cavity of the double gear ring under test. The outer circular spray mechanism 5 rinses the outer circumference of the double gear ring under test, removing oil stains and processing debris from the double gear ring. The telescopic spray column 203 can be moved up and down to adjust the rinsing position. After rinsing, the fluid supply mechanism supplies drying airflow into the telescopic spray column 203. The lifting cylinder 202 drives the telescopic spray column 203 to move up and down reciprocally. The airflow sprayed by the pressurized nozzle 204 dries the upper end face and inner teeth of the double gear ring under test. Since the double gear ring is inside the main housing 1, the airflow sprayed by the pressurized nozzle 204 can indirectly dry the outer circumference of the double gear ring under test due to the rebound effect of the inner wall of the main housing 1 and the moving carrier 3.

[0026] In a specific embodiment, the bearing lifting and rotating mechanism 10 includes a lifting rotating platform 1003 and a positioning bearing cylinder 1001. The lifting rotating platform 1003 is used to drive the double gear ring under test to move up and down and rotate. The positioning bearing cylinder 1001 is coaxially disposed on the top of the lifting rotating platform 1003 and is used to position and support the double gear ring under test. The positioning bearing cylinder 1001 is provided with a water guiding window 1002 in the circumferential direction. The water guiding window 1002 is used to allow the cleaning liquid after rinsing to flow out, so as to avoid water accumulation inside the positioning bearing cylinder 1001. The double gear ring under test is supported on the top of the positioning bearing cylinder 1001. The bearing surface at the top of the positioning bearing cylinder 1001 is constructed with a conical surface structure that matches the outer circumferential inclined surface of the gear ring to ensure that the gear ring under test is placed stably and positioned accurately.

[0027] In a specific embodiment, the radial runout detection mechanism 7 adopts a distance detection device; when the double gear ring to be tested is located in the third position and is driven to rotate by the bearing lifting and rotating mechanism 10, the distance detection device continuously detects the change in distance between itself and the nearest point on the outer periphery of the double gear ring to be tested, and calculates the radial runout of the outer periphery of the double gear ring to be tested based on the change in distance.

[0028] In a specific embodiment, the elastic pressing and flattening mechanism 6 includes guide posts 603, a pressing and moving plate 604, a flattening rotating ring 602, and a pressure spring 605. At least four guide posts 603 are provided, all vertically arranged within the detection cavity 301. Each guide post 603 penetrates the pressing and moving plate 604, guiding the pressing and moving plate 604 to move vertically up and down. The flattening rotating ring 602 is rotatably disposed within the central through hole of the pressing and moving plate 604. When the double gear ring to be tested rotates, the flattening rotating ring 602 rotates synchronously with the double gear ring. At least four probe flattening units 601 are circumferentially distributed on the flattening rotating ring 602. The probe flattening units 601 are used to contact the upper surface of the double gear ring to be tested for detection. Its flatness ensures that the double gear ring under test is placed stably. When the double gear ring under test is in the third position, the probe flattening unit 601 is also used to elastically abut against the upper end face of the double gear ring under test to provide a holding effect. The pressure spring 605 is sleeved on the guide post 603. The upper end of the pressure spring 605 abuts against the inner wall of the detection cavity 301 and the lower end abuts against the holding moving plate 604. It is used to apply continuous downward elastic pressure to the holding moving plate 604, thereby continuously applying pressure during the rising process of the double gear ring under test, and thus holding the upper end face of the gear ring to make fine adjustments, ensuring that the gear ring is accurately positioned and placed, and elastically pressing the double gear ring under test during the detection process, avoiding abnormal movement of the double gear ring under test during the detection and affecting the detection results.

[0029] When the coaxiality visual inspection mechanism 9 is inspecting the coaxiality of the inner teeth of the gear ring, the measuring rotating ring 602 can also provide an auxiliary shielding function to shield the surrounding interference structures inside the inspection cavity 301, ensuring that the coaxiality visual inspection mechanism 9 can accurately detect the coaxiality of the two inner teeth in the double gear ring under test; as an optimization measure to assist observation, the surface of the measuring rotating ring 602 can be provided with a light-shielding coating (e.g., a black coating) to further reduce reflection interference and assist visual inspection.

[0030] In a further embodiment, the probe leveling unit 601 includes a probe base 6013, a piston block 6014, a holding spring 6015, and a displacement sensor 6011. The probe base 6013 has an axially formed central hole 6012 and a movable cavity 6016 coaxially connected to the central hole 6012. The piston block 6014 is slidably disposed within the movable cavity 6016. The lower end of the piston block 6014 is connected to a leveling contact pin 6017, which extends through the central hole 6012 to the outside of the probe base 6013 for contacting the probe. The upper end face of the double gear ring is contacted; the holding spring 6015 is disposed in the moving cavity 6016, and is used to push the piston block 6014 to make the flat contact pin 6017 extend outward through the central hole 6012 to the outside, and thus maintain the extended state; the displacement sensor 6011 is coaxially disposed on the upper end of the probe seat 6013, and the detection end of the displacement sensor 6011 is connected to the upper end of the piston block 6014, and is used to detect the displacement of the piston block 6014. When the flat contact pin 6017 contacts the upper end face of the double gear ring, the flatness of the upper end face of the double gear ring to be measured can be measured.

[0031] When the double gear ring under test is in the second position, the flatness contact pins 6017 of each probe flatness measurement unit 601 contact the upper end face of the double gear ring under test. The displacement sensor 6011 detects the displacement of each flatness contact pin 6017. The flatness of the upper end face of the double gear ring under test is judged by comparing the difference in displacement of each probe flatness measurement unit 601. When the double gear ring continues to move upward, the flatness contact pins 6017 of each probe flatness measurement unit 601 elastically abut against the upper end face of the double gear ring under test. At this time, the flatness contact pins 6017 will be hidden in the center hole 6012. At this time, stable holding is achieved by the probe seat 6013.

[0032] In a specific embodiment, the meshing phase detection mechanism 8 includes two phase difference detection units. The two phase difference detection units are used to detect the rotation angles of the two internal teeth of the double gear ring to be tested, and then the phase difference between the two internal teeth is obtained by comparing the two rotation angles.

[0033] The phase difference detection unit includes a lateral feed driver 801, a probe slide 804, a rotating shaft 805, and an angle adjustment motor 802. The probe slide 804 is horizontally slidably mounted on the movable carrier 3. The output end of the lateral feed driver 801 is connected to the probe slide 804 and is used to drive the probe slide 804 to move horizontally, so that the probe slide 804 can move on a line parallel to the diameter of the double gear ring to be measured. The upper end of the rotating shaft 805 is coaxially connected to the probe slide 804, and the lower end of the rotating shaft 805 extends downward into the detection cavity 301 through a preset window on the movable carrier 3 and is coaxially connected to the phase measuring meshing gear 806. The angle adjustment motor 802 is mounted on the probe slide 804 and coaxially connected to the rotating shaft 805, and is used to drive the phase measuring meshing gear 806 to rotate to adjust its meshing angle. The angle encoder 803 is mounted on the angle adjustment motor 802 and is used to detect the rotation angle output by the motor.

[0034] During the testing process, the coaxiality visual inspection mechanism 9 is located directly above the double gear ring under test and can be used to visually monitor the rotation angle of the phase-meshing gear 806. When the transverse feed driver 801 drives the phase-meshing gear 806 to move closer to the central axis of the double gear ring under test, the coaxiality visual inspection mechanism 9 can monitor the rotation angle of the phase-meshing gear 806 in real time to determine whether the phase-meshing gear 806 and the corresponding internal teeth of the double gear ring under test have reached a precise meshing angle. The bearing lifting and rotating mechanism 10 drives the double gear ring under test to rotate to a preset angle according to the visual monitoring results, so that the phase-meshing gear 806 precisely meshes with the corresponding internal teeth of the double gear ring under test. Then, the two phase difference detection units detect the rotation angle of the two internal teeth of the double gear ring under test respectively and obtain the phase difference detection results.

[0035] In addition, the lateral feed driver 801 can also drive the probe slide 804 to retract outward or inward to avoid motion interference when the elastic pressing and measuring mechanism 6 moves up and down.

[0036] The coaxiality visual inspection mechanism 9 includes a visual imaging component and an image processing component. The visual imaging component is positioned above the movable carrier 3 and at the top of the detection cavity 301, and is used to acquire visual images of the inner teeth of the double-toothed ring under test. The image processing component is connected to the visual imaging component and is used to process and analyze the acquired visual images. By identifying the deviation of the center positions of the two inner teeth of the double-toothed ring under test, the coaxiality detection result of the two inner teeth is calculated. The coaxiality visual inspection mechanism 9 can also inspect the appearance, whether the cleaning is in place, and whether there are burrs or other problems.

[0037] After the phase difference detection is completed, the double toothed ring moves to a suitable height position. The coaxiality visual inspection mechanism 9 performs continuous visual imaging detection of the coaxiality of the inner teeth of the double toothed ring under test. The flat rotating ring 602 provides auxiliary shielding for the visual imaging component to shield the surrounding interference structure inside the detection cavity 301, so as to ensure the clarity and accuracy of the visual imaging.
