A strength testing device and method for machining shaft retaining rings

Abstract

This invention discloses a strength testing device and method for machining shaft retaining rings, belonging to the technical field of testing devices. It includes a frame, a camera mounted on the frame, a testing platform fixed to the frame, a displacement stage sliding at equal angles on the top of the testing platform, and an electric push rod positioned below the testing platform. When the limiting rod moves inside the inner straight guide rail, the clamping plate clamps the retaining ring and rotates its angle. When it moves to the outer straight guide rail, the clamping plate releases the retaining ring and resets. At this time, the convex plate pushes the piston rod, causing the piston rod to continuously move into the pressure tube. The elastic force of the first spring squeezes the oil inside the pressure rod through the pressure plate, and the pressure is transmitted to the retaining ring for strength testing through the pressure rod. During the testing process, the clamping plate is in a state of releasing the retaining ring and resetting. When the clamping plate rotates the retaining ring, the pressure rod no longer applies pressure for testing, realizing automatic rotational testing of the retaining ring area to ensure comprehensive coverage. This equipment significantly improves testing efficiency through automated collaborative operation.

Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically to a strength testing device and method for machining shaft retaining rings. Background Technology

[0002] Shaft retaining rings are bearing parts used to prevent components (such as bearings and gears) mounted on shafts from loosening or falling off. They mainly serve to suppress axial movement of bearings or other components, ensuring the stability of the transmission system. After production, retaining rings are sampled for strength testing to assess their reliability under extreme pressure and avoid potential risks caused by design or material defects. The strength testing device for shaft retaining rings is a dedicated testing equipment for retaining ring strength testing. Its core function is to test the mechanical properties of the retaining rings by simulating the pressure applied under actual working conditions and combining it with precision measurement technology.

[0003] The strength testing device and method for machining shaft retaining rings mainly involves applying pressure to the outer wall of the retaining ring using a hydraulic cylinder, displaying the pressure data through a pressure sensor, and observing the condition of the retaining ring in real time through a camera. When the retaining ring shows signs of deformation or cracking, the system connected to the camera will analyze the situation in a timely manner and record the pressure data at that time, thereby determining the maximum strength bearing range of the retaining ring and completing the strength test.

[0004] The aforementioned strength testing device for shaft retaining rings applies pressure to the retaining ring using a hydraulic cylinder and employs a camera and analysis system to analyze the real-time condition of the retaining ring for strength testing. It offers advantages such as high operational safety and accurate test data. However, during the retaining ring testing process, pressure needs to be applied to the entire outer wall of the retaining ring, and adjusting the angle by rotating the retaining ring presents a challenging problem in the testing work.

[0005] 1. Loosen the clamping strength of the clamping mechanism on the retaining ring so that the retaining ring can rotate under force. Then manually rotate the retaining ring. This operation can solve the problem of adjusting the angle of the retaining ring. However, to perform a comprehensive strength test on the outer wall of the retaining ring, the retaining ring needs to be rotated frequently. Manual operation is time-consuming and labor-intensive.

[0006] 2. When using a pulley or other drive device to rotate the retaining ring, the hydraulic system needs to be stopped from pressurizing; when the drive device stops rotating, the hydraulic system needs to be restarted from pressurizing. This repeated operation of the two devices is not only troublesome but also prone to errors.

[0007] Therefore, the present invention proposes a strength testing device and method for machining shaft retaining rings. Summary of the Invention

[0008] The present invention addresses the problem of overly simplistic solutions in existing technologies by providing a significantly different solution. Specifically, the present invention aims to provide a strength testing device and method for machining shaft retaining rings, thereby solving the problem mentioned in the background that it is difficult to achieve adaptive coordination between detection and adjustment angles (i.e., stopping detection when adjusting the retaining ring angle and automatically detecting after adjusting the retaining ring angle).

[0023] Preferably, the strength detection component includes a fixed column fixed to the displacement stage;

[0024] One end of the fixing post extends to the pressure rod, and the fixing post and the pressure rod are slidably connected;

[0025] A pressure tube is fixedly installed on the outer wall of the pressure rod, and a pressure plate is slidably connected to the inner wall of the pressure tube;

[0026] A first spring is fixedly installed on one side of the pressure plate, and a piston column is fixedly connected to one end of the first spring.

[0027] One end of the piston rod extends to the outside of the pressure tube, and the piston rod is slidably connected to the pressure tube.

[0028] Preferably, the control component includes a motor fixed to the displacement stage, and the rotation shaft of the motor is fixedly connected to the center of the rotating disk;

[0029] An eccentric rod is fixedly connected to one side of the rotating disk;

[0030] A protruding plate is fixedly connected to the outer wall of the rotating disk;

[0031] The convex plate has a semi-circular ring structure and its outer wall has a slope.

[0032] Preferably, the top of the displacement stage is provided with a slide rail at equal angles, and the inner wall of the slide rail is slidably connected with a reciprocating frame;

[0033] The reciprocating frame is a rectangular frame.

[0034] One end of the eccentric rod extends into the interior of the reciprocating frame, and the outer wall of the eccentric rod is slidably connected to the inner wall of the reciprocating frame;

[0035] A reciprocating rod is fixedly connected to one side of the reciprocating frame;

[0036] A connecting channel is provided on one side of the track plate, and the reciprocating rod is slidably sleeved with the limiting channel.

[0037] Preferably, the rotating component further includes a connecting rod fixed to one end of the reciprocating rod;

[0038] Both ends of the connecting rod are provided with grooves, and a second spring is fixedly connected to the inner wall of the groove;

[0039] A retractable rod is fixedly connected to the top of the second spring, and the retractable rod is slidably connected to the groove;

[0040] The outer wall of the retracting rod is fixedly connected to the clamping plate.

[0041] Preferably, a limit rod is fixedly connected to the outer wall of the retraction rod;

[0042] The track board has symmetrical guide slides on one side, and the limiting rod is slidably connected to the guide slides.

[0043] Preferably, the guide rail consists of four parts: an inner straight guide rail close to the connecting channel, an outer straight guide rail connecting the connecting channel, and two transition rails connecting the inner and outer straight guide rails.

[0044] Preferably, a pressure sensor is fixedly installed on the inner wall of the pressure rod.

[0045] A method for strength testing of a shaft retaining ring includes the following steps:

[0046] S1: Start the electric push rod to drive the drive table to move upward, so that the displacement plate moves "outward" at the same angle. Then place the retaining ring in the middle of multiple displacement plates, operate the electric push rod to retract its push rod head downward, so as to limit and support the retaining ring. Start the motor to drive the rotating disk to rotate, so that the eccentric rod drives the reciprocating frame, reciprocating rod, connecting rod and clamping plate to move back and forth.

[0047] S2: The limiting rod moves from the outer straight guide rail to the inner straight guide rail, and then from the inner straight guide rail to the outer straight guide rail, completing one revolution. When the limiting rod moves inside the inner straight guide rail, the clamping plate clamps the retaining ring and rotates the angle of the retaining ring. When the limiting rod moves to the outer straight guide rail, the clamping plate releases the retaining ring and resets. At this time, the convex plate pushes the piston rod, causing the piston rod to continue moving into the pressure tube. The elastic force of the first spring continues to squeeze the oil inside the pressure rod through the pressure plate. This pressure is applied to the retaining ring through the pressure rod to achieve strength testing of the retaining ring.

[0048] S3: When the pressure rod performs strength testing on the retaining ring, the clamping plate is in the process of releasing the retaining ring and resetting. When the clamping plate rotates to hold the retaining ring, the pressure rod no longer performs strength testing on the retaining ring. After one part of the retaining ring is tested, the clamping plate automatically rotates and adjusts the retaining ring so that the next untested part of the retaining ring rotates to the position corresponding to the pressure rod, and the pressure rod then performs strength testing on this part.

[0049] Compared with the prior art, the beneficial effects of the present invention are:

[0050] 1. The device moves from the outer straight guide rail to the inner straight guide rail and then back to the outer straight guide rail, completing one cycle. When the limit rod moves inside the inner straight guide rail, the clamping plate clamps the retaining ring and rotates its angle. When it moves to the outer straight guide rail, the clamping plate releases the retaining ring and resets. At this time, the convex plate pushes the piston rod, causing the piston rod to move continuously into the pressure tube. The elastic force of the first spring squeezes the oil inside the pressure rod through the pressure plate. The pressure is transmitted to the retaining ring for strength testing through the pressure rod. During the testing process, the clamping plate is in the state of releasing the retaining ring and resetting. When the clamping plate rotates the retaining ring, the pressure rod no longer applies pressure for testing, realizing automatic rotation testing of the retaining ring area to ensure comprehensive coverage. This device significantly improves testing efficiency through automated collaborative operation.

[0051] 2. Start the electric push rod to drive the drive platform to move upward, so that the displacement plates move "outward" at the same angle. Then, place the retaining ring in the middle of multiple displacement plates and operate the electric push rod to retract its push rod head downward, thereby limiting and supporting the retaining ring. This variable can be used to accommodate retaining rings of different diameters. Compared with the existing technology, this device has the advantages of simple operation, saving time and effort, and wide applicability. Attached Figure Description

[0069] 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, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0070] Please see Figures 1 to 16 The present invention provides a technical solution: a strength testing device for machining shaft retaining rings, comprising a frame 1, a camera end 2 mounted on the frame 1, a testing table 3 fixed on the frame 1, a displacement stage 44 sliding at equal angles on the top of the testing table 3, and an electric push rod 4 disposed below the testing table 3, and further comprising:

[0071] The control component is located on the top of the push rod head of the electric push rod 4 for adjusting the displacement table 44 at equal distances;

[0072] A strength detection component is installed on the displacement stage 44 that adaptively applies pressure based on the rotation state of the retaining ring.

[0073] The control component for automatic detection of the drive strength detection component is set on the displacement stage 44;

[0074] The trajectory plate 7 is fixed on the displacement stage 44 and the rotating component on one side of the trajectory plate 7 adaptively adjusts the angle of the retaining ring based on the detection status;

[0075] The strength detection component includes a pressure rod 51 for detecting the strength of the retaining ring;

[0076] The control component includes a rotating disk 61 for driving the strength detection component to apply pressure and adjusting the angle of the retaining ring;

[0077] The rotating component includes a clamping plate 68 for intermittently rotating the retaining ring angle.

[0078] In specific implementation, the camera terminal 2 is an existing device, which will not be explained in detail here. The camera terminal 2 can take pictures of the retaining ring and monitor the status of the retaining ring in real time through the computer system. When the retaining ring is deformed or cracked, the computer system will issue a prompt. The retaining ring is placed on the detection table 3 and the symmetrically arranged clamping plates 68 are respectively positioned above and below the retaining ring. When the clamping plates 68 move relative to each other, they clamp and fix the retaining ring. When the clamping plates 68 are displaced, they will adjust the angle of the retaining ring. During the angle adjustment of the retaining ring, the pressure rod 51 does not apply pressure to the retaining ring. After the rotation of the retaining ring stops, the pressure rod 51 applies pressure to the retaining ring.

[0079] The control components include a drive platform 41 fixed to the top of the push rod head of the electric push rod 4;

[0080] The electric push rod 4 is fixedly connected to the frame 1;

[0081] The outer wall of the drive platform 41 is provided with a rotating groove at equal angles, and a rotating shaft is fixedly installed on the inner wall of the rotating groove. The outer wall of the rotating shaft is rotatably sleeved with a drive plate 42.

[0082] One end of the drive plate 42 is rotatably mounted with a support frame, and a displacement plate 43 is fixedly connected to one side of the support frame;

[0083] The top of the displacement plate 43 is fixedly connected to the bottom of the displacement stage 44;

[0084] The top of the testing platform 3 has a limit channel at an equal angle, and the displacement plate 43 is slidably connected to the limit channel.

[0085] In the specific implementation, the electric push rod 4 is an existing device and will not be explained in detail here. When the electric push rod 4 is started, the push rod head of the electric push rod 4 drives the drive platform 41 to move upward. The drive plate 42 is inclined, so when the drive platform 41 moves upward, the distance between the drive platform 41 and the displacement plate 43 decreases, and the displacement plate 43 rotates to the horizontal state. Therefore, the displacement plate 43 will push the displacement plate 43 to move, thereby driving the displacement plate 43 to move "outward" at the same angle. The distance between multiple displacement plates 43 increases, and the retaining ring can be placed in the middle of multiple displacement plates 43. Similarly, when the push rod head of the electric push rod 4 retracts downward, multiple displacement plates 43 will move relative to each other, which makes it easier for the clamping plate 68 to clamp the retaining ring.

[0086] The strength detection component includes a fixed column 5 fixed on the displacement stage 44;

[0087] One end of the fixing post 5 extends to the pressure rod 51, and the fixing post 5 and the pressure rod 51 are slidably connected;

[0088] The outer wall of the pressure rod 51 is fixedly installed with a pressure tube 53, and the inner wall of the pressure tube 53 is slidably connected with a pressure plate 56.

[0089] A first spring 55 is fixedly installed on one side of the pressure plate 56, and a piston column 54 is fixedly connected to one end of the first spring 55.

[0090] One end of the piston rod 54 extends to the outside of the pressure tube 53, and the piston rod 54 is slidably connected to the pressure tube 53.

[0091] In practice, the inside of the pressure rod 51 and the part where the pressure tube 53 connects to the pressure rod 51 are filled with oil. The preload of the first spring 55 is relatively large. When the piston rod 54 extends into the pressure tube 53, the oil is squeezed by the first spring 55 and the pressure plate 56. At this time, the oil inside the pressure tube 53 is squeezed into the inside of the pressure rod 51. The oil inside the pressure rod 51 increases, so more space is needed. Therefore, the pressure rod 51 will move towards the retaining ring. The pressure rod 51 adheres to and squeezes the outer wall of the retaining ring. When the piston rod 54 continues to move into the pressure tube 53, the first spring 55 is compressed because the pressure rod 51 has no space to move. The elastic force of the first spring 55 continues to squeeze the oil inside the pressure rod 51 through the pressure plate 56. This pressure will be applied to the retaining ring through the pressure rod 51. When the piston rod 54 is subjected to a strong force, the pressure rod 51 will apply strong pressure to the retaining ring, thus realizing the strength test of the retaining ring.

[0092] The control component includes a motor 6 fixed on the displacement stage 44, and the rotation shaft of the motor 6 is fixedly connected to the center of the rotating disk 61.

[0093] An eccentric rod 62 is fixedly connected to one side of the rotating disk 61;

[0094] A protruding plate 69 is fixedly connected to the outer wall of the rotating disk 61;

[0095] The convex plate 69 has a semi-circular ring structure and its outer wall has a slope.

[0096] In the specific implementation, the motor 6 is started, and the rotating shaft of the motor 6 drives the rotating disk 61 to rotate. The convex plate 69 follows the rotation of the rotating disk 61 and passes through the piston column 54. The convex plate 69 is a protruding part of the rotating disk 61 and the protruding part has a slope. Therefore, when the convex plate 69 rotates, it will gradually push the piston column 54, so that the piston column 54 moves forcefully into the interior of the pressure tube 53.

[0097] The top of the displacement stage 44 is provided with a slide rail at equal angles, and the inner wall of the slide rail is slidably connected with a reciprocating frame 63.

[0098] The reciprocating frame 63 is a rectangular frame.

[0099] One end of the eccentric rod 62 extends into the interior of the reciprocating frame 63, and the outer wall of the eccentric rod 62 is slidably connected to the inner wall of the reciprocating frame 63.

[0100] A reciprocating rod 64 is fixedly connected to one side of the reciprocating frame 63;

[0101] A connecting channel is provided on one side of the track plate 7, and the reciprocating rod 64 is slidably sleeved with the limiting channel.

[0102] In specific implementation, the eccentric rod 62 is fixed at the edge of the surface of the rotating disk 61. When the rotating disk 61 rotates, the movement trajectory of the eccentric rod 62 is also circular. When the eccentric rod 62 rotates, it will slide inside the reciprocating frame 63. The reciprocating frame 63 can be moved through the slide rail. When the eccentric rod 62 rotates half a turn, it will drive the reciprocating frame 63 to move to the other side of the slide rail. When the eccentric rod 62 rotates one turn, it will drive the reciprocating frame 63 to reset. Therefore, the reciprocating frame 63 reciprocates with the rotation of the rotating disk 61.

[0103] The rotating component also includes a connecting rod 65 fixed to one end of the reciprocating rod 64;

[0104] Both ends of the connecting rod 65 are provided with grooves, and the inner wall of the groove is fixedly connected with a second spring 66.

[0105] The top of the second spring 66 is fixedly connected to a retractable rod 67, which is slidably connected to the groove.

[0106] The outer wall of the retraction rod 67 is fixedly connected to the clamping plate 68.

[0107] In practice, the reciprocating frame 63 drives the connecting rod 65 and the clamping plate 68 to move back and forth via the reciprocating rod 64. When the clamping plate 68 clamps and fixes the retaining ring, its rotation can drive the retaining ring to change its angle.

[0108] The outer wall of the retraction rod 67 is fixedly connected to the limiting rod 671;

[0109] The track plate 7 is symmetrically provided with guide slides 71 on one side, and the limiting rod 671 is slidably connected to the guide slides 71.

[0110] In practice, the limiting rod 671 can only slide inside the guide slide 71, and the limiting rod 671 will not detach from the track plate 7.

[0111] The guide slide 71 consists of four parts: an inner straight guide rail close to the connecting channel, an outer straight guide rail connecting the connecting channel, and two transition rails connecting the inner and outer straight guide rails.

[0112] In the specific implementation, one inner wall of the two transition tracks is an arc-shaped surface, and the other inner wall is a combination of an arc-shaped surface and a straight surface. When the limiting rod 671 moves on the outer straight guide rail, it first passes through the transition track composed of the arc-shaped surface and the straight surface. The limiting rod 671 will follow the arc-shaped surface and be inserted into the straight surface by inertia. Since the angle between the arc-shaped surface and the straight surface is close to 90 degrees, the limiting rod 671 moves directly to the inner straight guide rail along the straight surface during the reset movement. This process causes the two clamping plates 68 to move relative to each other, thereby clamping the retaining ring. At this time, the second spring 66 is in a compressed state. When the limiting rod 671 continues to move and passes through the transition track with the arc-shaped surface, the limiting rod 671 will move back to the inside of the outer straight guide rail along the transition track by the elastic force of the second spring 66. The clamping plate 68 will then reset and release the retaining ring.

[0113] A pressure sensor 52 is fixedly installed on the inner wall of the pressure rod 51.

[0114] In practice, the pressure sensor 52 is an existing device, model “OUMENS-MSZ11”, which can detect the pressure on the pressure rod 51, that is, the intensity of the pressure applied to the retaining ring.

[0115] A method for strength testing of a shaft retaining ring includes the following steps:

[0116] S1: Start the electric push rod 4 to drive the drive table 41 to move upward, so that the displacement plate 43 moves "outward" at the same angle. Then, place the retaining ring in the middle of multiple displacement plates 43, operate the electric push rod 4 to retract its push rod head downward, so as to limit and support the retaining ring. Start the motor 6 to drive the rotating disk 61 to rotate, so that the eccentric rod 62 drives the reciprocating frame 63, reciprocating rod 64, connecting rod 65 and clamping plate 68 to move back and forth.

[0117] S2: The limiting rod 671 moves from the inner straight guide rail to the outer straight guide rail, and then from the inner straight guide rail to the outer straight guide rail, completing one revolution. When the limiting rod 671 moves inside the inner straight guide rail, the clamping plate 68 clamps the retaining ring and rotates the angle of the retaining ring. When the limiting rod 671 moves to the outer straight guide rail, the clamping plate 68 releases the retaining ring and resets. At this time, the convex plate 69 pushes the piston column 54, causing the piston column 54 to continue moving into the pressure tube 53. The elastic force of the first spring 55 continues to squeeze the oil inside the pressure rod 51 through the pressure plate 56. This pressure will be applied to the retaining ring through the pressure rod 51 to achieve strength testing of the retaining ring.

[0118] S3: When the pressure rod 51 performs strength testing on the retaining ring, the clamping plate 68 is in the process of releasing the retaining ring and resetting. When the clamping plate 68 rotates to clamp the retaining ring, the pressure rod 51 no longer performs strength testing on the retaining ring. After one part of the retaining ring is tested, the clamping plate 68 automatically rotates and adjusts the retaining ring so that the next untested part of the retaining ring rotates to the position corresponding to the pressure rod 51, and the pressure rod 51 then performs strength testing on this part.

[0119] Working principle: When using the strength testing device for machining retaining rings on this shaft, the electric push rod 4 is activated to drive the drive table 41 to move upward. When the drive table 41 moves upward, it causes the displacement plate 43 to rotate horizontally. Therefore, the displacement plate 43 will push the displacement plate 43 to move, thereby causing the displacement plate 43 to move "outward" at the same angle. The distance between the multiple displacement plates 43 increases, and the retaining ring is placed in the middle of the multiple displacement plates 43. The electric push rod 4 is operated to retract its push rod head downward, so that the multiple displacement plates 43 move relative to each other, thereby limiting and supporting the retaining ring.

[0120] The starter motor 6 drives the rotating disk 61 to rotate, and the eccentric rod 62 and the convex plate 69 follow the rotation. When the eccentric rod 62 rotates, it slides inside the reciprocating frame 63, and the reciprocating frame 63 can move through the slide rail. When the eccentric rod 62 rotates half a turn, it will drive the reciprocating frame 63 to move to the other side of the slide rail. When the eccentric rod 62 rotates one turn, it will drive the reciprocating frame 63 to reset. Therefore, the reciprocating frame 63 reciprocates with the rotation of the rotating disk 61. The reciprocating frame 63 drives the connecting rod 65 and the clamping plate 68 to reciprocate through the reciprocating rod 64.

[0121] When the limiting rod 671 moves along the outer straight guide rail, it first passes through a transition track composed of a curved surface and a straight surface. The limiting rod 671 will follow the curved surface and be inserted into the straight surface by inertia. Therefore, when the limiting rod 671 moves directly along the straight surface to the inner straight guide rail during the reset movement, the two clamping plates 68 move relative to each other to clamp the retaining ring. At this time, the second spring 66 is in a compressed state.

[0122] As the limiting rod 671 moves within the inner straight guide rail, it drives the clamping plate 68 to move. At this time, the clamping plate 68 is clamping the retaining ring, thus causing the retaining ring to adjust its angle. When the limiting rod 671 passes through the transition track of the arc surface, it moves back to the inner side of the outer straight guide rail by the elastic force of the second spring 66. The clamping plate 68 then resets and releases the retaining ring. This achieves automatic rotation adjustment of the retaining ring after the clamping plate 68 clamps and fixes it. After the angle adjustment is completed, the retaining ring is automatically released and reset. When the limiting rod 671 moves repeatedly within the guide slide 71, the clamping plate 68 repeatedly clamps and rotates the retaining ring, and then releases the retaining ring. This process is similar to manually holding the retaining ring, rotating it a certain angle, releasing it, and then returning to hold the retaining ring and rotating it again.

[0123] As the convex plate 69 rotates with the rotating disk 61, it passes over the piston rod 54. The convex plate 69 gradually pushes the piston rod 54, causing it to move forcefully into the pressure tube 53. The piston rod 54 squeezes the oil through the first spring 55 and the pressure plate 56. At this time, the oil inside the pressure tube 53 is squeezed into the pressure rod 51. The increased oil inside the pressure rod 51 requires more space, so the pressure rod 51 adheres to and squeezes the outer wall of the retaining ring. The convex plate 69 has a slope, which allows the piston rod 54 to continuously apply pressure. As the tube 53 moves internally, the pressure rod 51 has no space to move, so the first spring 55 is compressed. The elastic force of the first spring 55 continues to squeeze the oil inside the pressure rod 51 through the pressure plate 56. This pressure is applied to the retaining ring through the pressure rod 51. The piston rod 54 is subjected to a strong force from the convex plate 69. The pressure rod 51 applies strong pressure to the retaining ring, thus realizing the strength detection of the retaining ring. The pressure sensor 52 can detect the pressure on the pressure rod 51, that is, the strength of the pressure applied to the retaining ring.

[0124] During the process of the protruding plate 69 pushing the piston column 54, the clamping plate 68 is in the process of releasing the retaining ring and resetting. After the protruding plate 69 passes the piston column 54, the clamping plate 68 is in the process of clamping and rotating the retaining ring. Therefore, after one part of the retaining ring is tested, the clamping plate 68 automatically rotates and adjusts the retaining ring so that the untested part of the retaining ring rotates to the position corresponding to the pressure rod 51. The pressure rod 51 then performs a strength test on this part.

[0125] It should be noted that the side of the clamping plate 68 that clamps the retaining ring can be provided with several retractable balls. Therefore, when the clamping plate 68 clamps the retaining ring and rotates the angle of the retaining ring, the retraction of the balls will not affect the clamping effect on the retaining ring. When the clamping plate 68 releases the retaining ring and resets, the balls are exposed and in contact with the surface of the retaining ring, which does not affect the reset of the clamping plate 68.

[0126] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
