At this time, the protrusion rotates, causing the cleaning assembly to vibrate, cleaning dust and impurities on the surface of the cleaning assembly, and using machinery instead of manual handling to avoid the smooth surface of the heavier annular member, which makes it difficult to find the force application point during manual handling, which is prone to danger.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. In order to ensure that the detection probe is perpendicular to the detection surface of the part, the position and angle of the part need to be constantly adjusted. For large and heavy annular parts, the angle adjustment needs to be done manually, which imposes a heavy burden on the manual labor. The present invention sets an auxiliary mechanism to enable the annular part to be placed on the rotating shaft more stably, which is convenient for detection.

The handling work will bring certain risks to the staff. The present invention arranges a feeding mechanism, and the driving assembly drives the ring-shaped parts to move along the inclined plate. During the movement, the cleaning assembly cleans the outer wall of the ring-shaped parts, so that the surface of the ring-shaped parts can be kept clean during measurement to avoid contamination of the measurement module.

[0017] 3. The present invention sets a driving assembly so that the annular member is stuck on the one-way rod and contacts the bottom of the cleaning assembly. After the annular member is placed on the rotating shaft, the limit plate moves away from the first mounting plate, so that the one-way rod rotates clockwise and is taken out of the annular member, so that the first telescopic rod drives the cleaning assembly and the one-way rod away from the annular member. At this time, the protrusion rotates to make the cleaning assembly vibrate, and the dust and impurities on the surface of the cleaning assembly are cleaned. Mechanical handling is used instead of manual handling to avoid the smooth surface of the heavier annular member, which makes it difficult to find the force application point during manual handling and is prone to danger.

[0018] 4. The present invention sets a supporting component so that the edge of the annular member is inserted into the inner wall of the arc-shaped shell, and the annular member is clamped under the drive of the extrusion wheel. When the annular member rotates under the drive of the rotating shaft, there is a supporting force on both sides of the annular member to maintain the stability of the annular member, and the position of the arc-shaped shell and the limit rod will not block the measuring module, so that the surface of the annular member contacts the measuring module to complete the measurement, thereby enhancing the stability during the measurement process, ensuring the accuracy of the measurement, and reducing the workload of the staff.

[0030] It comprises: a main body mechanism 1, and a lifting column 2 is symmetrically arranged on the top of the main body mechanism 1;

[0031] The stress detection equipment for the rotating parts of the aircraft engine also includes:

[0032] A feeding mechanism 5, the bottom of which is fixedly connected to the top of the main mechanism 1;

[0033] The top of the lifting column 2 is fixedly connected to the frame 3, the bottom of the frame 3 is slidably connected to the measuring module 4, the top of the main mechanism 1 is symmetrically provided with an auxiliary mechanism 6 on one side away from the feeding mechanism 5, and the bottom of the auxiliary mechanism 6 is fixedly connected to the top of the main mechanism 1.

[0034] During work, the worker pushes the main mechanism 1 to the vicinity of the annular part to be measured, places the annular part with its curved surface on the ground, brings the feeding mechanism 5 close to the annular part, hangs the annular part on the feeding mechanism 5, and cleans the surface of the annular part while the feeding mechanism 5 drives the annular part to rotate. The feeding mechanism 5 drives the annular part to be placed inside the main mechanism 1, and enables the auxiliary mechanism 6 to clamp the two ends of the annular part, so that the annular part can rotate more stably under the drive of the main mechanism 1. The lifting column 2 drives the measuring module 4 on the frame 3 to approach the annular part, so that the measuring module 4 measures various places on the surface of the annular part. After the measurement is completed, the annular part is removed.

[0035] The main body mechanism 1 includes a cart 101, the inner wall of which is symmetrically provided with a rotating shaft 102, the outer wall of which is rotatably connected to the inner wall of the cart 101, the inner wall of which is symmetrically provided with an inclined plate 103, the outer wall of which is rotatably connected to the inner wall of the cart 101, and the surface of the inclined plate 103 is symmetrically provided with a limit strip 104, the position distance between the limit strips 104 is determined according to the height of different annular parts, so that the annular parts can move more stably, and the bottom of the limit strip 104 is slidably connected to the top of the inclined plate 103.

[0036] When in use, push the cart 101 to the vicinity of the annular part to be measured. After the feeding mechanism 5 holds the annular part, the feeding mechanism 5 drives the annular part to move along the inclined plate 103, and the annular part is placed on the rotating shaft. The rotation of the rotating shaft drives the annular part to rotate, and then the auxiliary mechanism 6 clamps the two sides of the annular part, so that the annular part can be more stable under the drive of the rotating shaft, and the measuring module 4 can have more comprehensive contact with the surface of the annular part, so that the measurement data is more and more accurate.

[0037] The loading mechanism 5 includes a first lifting column 501, which automatically adjusts its height during the movement of the annular member along the inclined plate 103, so that the driving component 504 maintains contact with the inner wall of the annular member and generates a force to move the annular member to maintain the stability of the annular member. The bottom of the first lifting column 501 is fixedly connected to the top of the main mechanism 1, and the top of the first lifting column 501 is fixedly connected to the first frame plate 502, and the first frame plate 502 is L-shaped. The outer wall of the first frame plate 502 is fixedly connected to the first telescopic rod 503, and the end of the first telescopic rod 503 away from the first frame plate 502 is fixedly connected to the driving component 504, and the top of the driving component 504 is rotatably connected to the cleaning component 505.

[0038] When in use, the first telescopic rod 503 is extended to move the driving assembly 504 away from the first frame plate 502, pushing the annular part close to the driving assembly 504 so that the annular part is sleeved on the driving assembly 504, and then the driving assembly 504 drives the annular part to move along the inclined plate 103. During the movement, the cleaning assembly 505 cleans the outer wall of the annular part so that the surface of the annular part can be kept clean during measurement to avoid contamination of the measuring module 4, so that the annular part can be rolled for loading, which facilitates the movement of the annular part, reduces the burden on the staff, keeps the surface of the annular part clean before measurement, and maintains the accuracy of the measurement results.

[0039] The auxiliary mechanism 6 includes a second lifting column 601, the bottom of the second lifting column 601 is fixedly connected to the top of the cart 101, the top of the second lifting column 601 is fixedly connected to a second frame plate 602, the outer wall of the second frame plate 602 is fixedly connected to a second telescopic rod 603, and the end of the second telescopic rod 603 away from the second frame plate 602 is fixedly connected to a supporting component 604.

[0040] After the annular part is placed on the rotating shaft, the feeding mechanism 5 is away from the annular part, and the second telescopic rod 603 drives the supporting assembly 604 to penetrate into the annular part and clamp the annular part from both sides, so that the annular part can be placed on the rotating shaft more stably for easy detection. After the measurement is completed, the supporting assembly 604 moves the annular part away from the rotating shaft along the inclined plate 103, so that the annular part can be unloaded stably, the stability of the annular part is maintained during the measurement process, and the heavier annular part can be rotated during the detection process, so that the surface of the annular part can contact the measuring module 4, so that more points are measured and the measurement accuracy is improved.

[0041] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of embodiment 1, the driving assembly 504 includes a first mounting plate 5041, the outer wall of the first mounting plate 5041 is fixedly connected to the outer wall of the first telescopic rod 503, the inner wall of the first mounting plate 5041 is rotatably connected to a one-way rod 5042, the surface of the one-way rod 5042 is smooth to reduce friction, the rotation direction of the one-way rod 5042 can only rotate one side at a time, and the end of the one-way rod 5042 away from the first mounting plate 5041 is rotatably connected to a protrusion 504 3. When the one-way rod 5042 is passed into the annular member, the protruding part of the protrusion 5043 faces downward, and the one-way rod 5042 is slidably connected to the limiting plate 5044 near the outer wall of one end of the first mounting plate 5041. When the limiting plate 5044 is close to the first mounting plate 5041, the one-way rod 5042 can only rotate counterclockwise. When the limiting plate 5044 is away from the first mounting plate 5041, the one-way rod 5042 can rotate clockwise, and the outer wall of the limiting plate 5044 contacts the outer wall of the first mounting plate 5041.

[0042] Initially, the annular member is placed upright, and the first telescopic rod 503 drives the one-way rod 5042 to approach the annular member, so that the one-way rod 5042 is inserted into the annular member. At this time, the limiting plate 5044 is close to the first mounting plate 5041, and the one-way rod 5042 is close to the inner wall of the annular member, so that the one-way rod 5042 presses against the inner wall of the annular member, and the first telescopic rod 503 drives the one-way rod 5042 to move, so that the one-way rod 5042 drives the annular member to move along the inclined plate 103. After the one-way rod 5042 passes through the annular member, the protrusion 5043 rotates 180 degrees, so that the annular member is stuck on the one-way rod 5044. 2 and contacts with the bottom of the cleaning component 505. After the ring is placed on the rotating shaft, the limiting plate 5044 is away from the first mounting plate 5041, so that the one-way rod 5042 rotates clockwise and is taken out of the ring, so that the first telescopic rod 503 drives the cleaning component 505 and the one-way rod 5042 away from the ring. At this time, the protrusion 5043 rotates to make the cleaning component 505 vibrate, and the dust and impurities on the surface of the cleaning component 505 are cleaned. Mechanical handling is used instead of manual handling to avoid the smooth surface of the heavy ring, which makes it difficult to find the force application point during manual handling, which is easy to cause danger.

[0043] The cleaning component 505 includes a cover shell 5051, which is made of plastic. The outer wall of the cover shell 5051 is rotatably connected to the top of the first mounting plate 5041, and the inner wall of the cover shell 5051 is evenly provided with rotating rods 5052. There are three rotating rods 5052, so that the cleaning cloth 5053 forms a triangle. When in contact with the surface of the annular member, the cleaning cloth 5053 and the surface of the annular member can generate a certain pressure, which is convenient for the cleaning cloth 5053 to clean the surface of the annular member. The outer wall of the rotating rod 5052 is rotatably connected to the inner wall of the cover shell 5051, and the outer wall of the rotating rod 5052 is provided with a cleaning cloth 5053. The inner wall of the cleaning cloth 5053 is socketed with the outer wall of the rotating rod 5052. The inner wall of the cover shell 5051 is evenly provided with a scraper 5054 at one end away from the rotating rod 5052. The scraper 5054 is made of rubber, and the outer wall of the scraper 5054 is fixedly connected to the inner wall of the cover shell 5051.

[0044] When the one-way rod 5042 is inserted into the inner wall of the ring part, the cover shell 5051 rotates to make the scraper 5054 contact the surface of the ring part. During the rotation of the ring part, the scraper 5054 contacts the surface of the ring part and scrapes off impurities. Then the cleaning cloth 5053 wipes the fine dust on the surface of the ring part, so that the ring part can be cleaned during the loading process, so that the surface of the ring part can be kept free of contamination by debris when placed on the rotating shaft, thereby preventing the external environment from affecting the accuracy of detection.

[0045] The supporting assembly 604 includes a second mounting plate 6041, the outer wall of the second mounting plate 6041 is fixedly connected to the outer wall of the second telescopic rod 603, the inner wall of the second mounting plate 6041 is rotatably connected to the limiting rod 6042, and the inner wall of the second mounting plate 6041 is rotatably connected to the limiting block 6046 on the side away from the limiting rod 6042. The limiting block 6046 can control the rotation direction of the limiting rod 6042. When the limiting block 6046 is placed in the same direction as the axis of the limiting rod 6042, the limiting rod 6042 rotates clockwise. When block 6046 is placed perpendicular to the axial direction of the limiting rod 6042, the limiting rod 6042 can rotate on both sides, and the end of the outer wall of the second mounting plate 6041 away from the limiting rod 6042 is fixedly connected to the third telescopic rod 6043, and the end of the third telescopic rod 6043 away from the second mounting plate 6041 is fixedly connected to the arc shell 6044, and the inner wall of the arc shell 6044 is evenly provided with extrusion wheels 6045, and the outer wall of the extrusion wheel 6045 is rotatably connected to the inner wall of the arc shell 6044, and the extrusion wheel 6045 is made of a material with relatively large elasticity.

[0046] After the annular member is placed on the rotating shaft, the second telescopic rod 603 drives the limiting rod 6042 to approach the annular member, so that the limiting rod 6042 penetrates into the annular member from both sides and contacts with the inner wall of the annular member, and the third telescopic rod 6043 drives the arc shell 6044 to approach both sides of the annular member, so that the edge of the annular member is inserted into the inner wall of the arc shell 6044, and the annular member is clamped under the drive of the extrusion wheel 6045, so that when the annular member rotates driven by the rotating shaft, there is supporting force on both sides to keep the annular member stable, and the positions of the arc shell 6044 and the limiting rod 6042 will not block the measuring module 4, so that the surface of the annular member contacts with the measuring module 4 to complete the measurement, enhance the stability during the measurement process, can ensure the accuracy of the measurement, and also reduce the workload of the staff.

[0047] The specific workflow is as follows:

[0048] During work, the worker pushes the main mechanism 1 to the vicinity of the annular part to be tested, places the annular part with its curved surface on the ground, extends the first telescopic rod 503, moves the driving assembly 504 away from the first frame plate 502, pushes the annular part close to the driving assembly 504, and puts the annular part on the driving assembly 504, then the driving assembly 504 drives the annular part to move along the inclined plate 103, during the movement, the cleaning assembly 505 cleans the outer wall of the annular part, so that the feeding mechanism 5 drives the annular part to be placed inside the main mechanism 1, and the second telescopic rod 603 drives the supporting assembly 604 to penetrate into the annular part and clamp the annular part from both sides, so that the annular part can be placed more stably on the rotating shaft for easy detection. After the measurement is completed, the supporting assembly 604 moves the annular part away from the rotating shaft along the inclined plate 103, so that the annular part can be stably unloaded, the lifting column 2 drives the measuring module 4 on the frame 3 close to the annular part, so that the measuring module 4 measures various parts of the surface of the annular part, and after the measurement is completed, the annular part is removed.
