Description

Technical Field

[0001] This utility model relates to the field of ball pin detection technology, specifically a protective mechanism for ball pin eddy current flaw detection. Background Technology

[0002] The ball pin eddy current flaw detection mechanism is a mechanism that can use the eddy current principle to detect the ball head surface of the connecting rod ball pin. It can effectively detect whether there are defects such as cracks and pores on the ball head surface of the connecting rod ball pin. Before detecting the ball head surface of the connecting rod ball pin, the probe of the connecting rod ball pin eddy current flaw detection mechanism is first adjusted. After the probe is adjusted to the actual required position, the probe is just in contact with the ball head surface of the connecting rod ball pin with appropriate force. At this time, the ball head of the connecting rod ball pin will rotate under the action of the rotating device, thereby completing the detection of the entire circumference of the ball head at that height position.

[0003] During the production of connecting rod ball pins, surface scratch inspection using an eddy current flaw detector is required. However, during feeding and inspection within the eddy current flaw detector, some ball pins may fall from a suspended position into the machine. Existing eddy current flaw detectors do not effectively handle these falls, causing the ball pins to collide with components inside the detector during their descent. This results in scratches, dents, and other damage to the surface of the ball pins, reducing product quality and potentially leading to scrapping. This significantly impacts subsequent surface treatment and performance.

[0004] Therefore, a protective mechanism for eddy current flaw detection of ball pins is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a protective mechanism for eddy current flaw detection of ball pins, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for eddy current flaw detection of ball pins, comprising a testing platform, a placement frame fixedly connected to the top of the testing platform, a rectangular hole opened in the middle of the testing platform directly below the placement frame, a flaw detection mechanism fixedly connected to one side of the top of the testing platform, a pointed hole detection mechanism fixedly connected to the other side of the top of the testing platform, electric telescopic rods rotatably connected to both sides of the bottom of the testing platform, right-angle plates rotatably connected to both sides of the bottom of the testing platform, the telescopic rod ends of the electric telescopic rods on both sides being rotatably connected to the middle of the outer wall of the right-angle plates on both sides, a connecting spring sleeved on the outer wall of the electric telescopic rods on both sides, one end of the connecting spring being fixedly connected to the testing platform, and the other end of the connecting spring being fixedly connected to the right-angle plate, a plurality of rubber columns rotatably connected to the top of the right-angle plates on both sides, and lifting rings fixedly connected to both sides of the bottom of the testing platform.

[0007] Preferably, a storage frame is provided in the middle of the two hanging rings, and a sponge board is slidably connected to the inner wall of the storage frame.

[0008] Preferably, hollow columns are rotatably connected to both sides of the inner wall of the testing platform, and connecting rods are slidably connected to the inner walls of both hollow columns.

[0009] Preferably, a pin is slidably connected to the middle of the inner wall of the storage frame, and a support post is fixedly connected to the top of the pin.

[0010] Preferably, the ends of the connecting rods on both sides away from the hollow column are rotatably connected to the middle of the receiving column, and a return spring is sleeved on the outer wall of the pin.

[0011] Preferably, one end of the return spring is fixedly connected to the receiving post, and the other end of the return spring is fixedly connected to the storage frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. By setting a flexible transfer mechanism at the bottom of the testing table to receive the ball pins, the impact force of the ball pins during the transfer process can be effectively buffered, reducing surface and internal damage caused by falling or collision. It can adapt to ball pins of different shapes and sizes, ensuring their stability during the transfer process and preventing tilting or rolling. The use of flexible materials can effectively absorb vibration and impact, reduce noise during the transfer process, and the stable transfer process can ensure the accurate position of the ball pins during testing, which helps to improve the accuracy and reliability of testing methods such as eddy current testing. Through the automated transfer mechanism, fast and continuous transfer can be achieved, reducing manual intervention, improving production efficiency, and shortening the testing cycle.

[0014] 2. By setting up a flexible receiving and collecting mechanism for the ball pins after testing, the ball pins fall onto the right-angle plates on both sides after processing. Then, the electric telescopic rods on both sides operate, causing the right-angle plates to rotate and tilt, thus conveying the ball pins on the rubber column to the sponge plate. Under the action of gravity, the sponge plate compresses the return spring downward, causing the pin to slide downward. With the assistance of the connecting rods on both sides, the downward movement of the sponge plate is more stable. The flexible receiving and collecting mechanism can simplify the operation process, reduce the labor intensity of workers, and improve the safety of operation. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 5 The present invention provides an embodiment of a protective mechanism for ball pin eddy current flaw detection, comprising a testing platform 1, a placement frame 2 fixedly connected to the top of the testing platform 1, a rectangular hole 5 opened in the middle of the testing platform 1 directly below the placement frame 2, a flaw detection mechanism 3 fixedly connected to one side of the top of the testing platform 1, a pointed hole detection mechanism 4 fixedly connected to the other side of the top of the testing platform 1, electric telescopic rods 6 rotatably connected to both sides of the bottom of the testing platform 1, right angle plates 8 rotatably connected to both sides of the bottom of the testing platform 1, the telescopic rod ends of the two electric telescopic rods 6 rotatably connected to the middle of the outer wall of the two right angle plates 8, a connecting spring 7 sleeved on the outer wall of the two electric telescopic rods 6, one end of the connecting spring 7 fixedly connected to the testing platform 1, the other end of the connecting spring 7 fixedly connected to the right angle plate 8, a plurality of rubber columns 9 rotatably connected to the top of the two right angle plates 8, and lifting rings 10 fixedly connected to both sides of the bottom of the testing platform 1;

[0024] Among them: each ball pin is inserted into the middle of the placement frame 2, and the flaw detection mechanism 3 and the tip detection mechanism 4 are both set directly above the middle of the placement frame 2;

[0025] Even better: After the flaw detection mechanism 3 and the pin detection mechanism 4 have inspected each ball pin in the middle of the placement frame 2, the ball pin can be transported downward through the rectangular hole 5 to the top of the right angle plates 8 on both sides. The ball pin falls on the top of each rubber column 9 and is buffered and protected. After the transport is completed, the electric telescopic rods 6 on both sides are operated to push the right angle plates 8 on both sides to rotate downward relative to each other, and each ball pin can roll down along each rubber column 9.

[0026] A storage frame 11 is provided in the middle of the two side hanging rings 10. A sponge board 12 is slidably connected to the inner wall of the storage frame 11. Hollow columns 13 are rotatably connected to both sides of the inner wall of the testing table 1. Connecting rods 14 are slidably connected to the inner walls of both hollow columns 13. A pin 16 is slidably connected to the middle of the inner wall of the storage frame 11. A receiving column 15 is fixedly connected to the top of the pin 16. One end of the return spring 17 is fixedly connected to the receiving column 15, and the other end of the return spring 17 is fixedly connected to the storage frame 11.

[0027] Among them: the storage frame 11, the right angle plate 8, and the rectangular hole 5 are located on the same vertical line, and the upper and lower ends of the outer wall of the pin 16 are provided with baffles to limit its position;

[0028] Even better: After each ball pin slides down, it can land on the sponge plate 12. The flexible contact protects the ball pin. Under the pressure of the weight of the ball pin, the sponge plate 12 can slide down. The downward force will act on the return spring 17 to deform it and make the pin 16 slide down. As the pin 16 moves, the hollow columns 13 on both sides can rotate downward, so that the connecting rod 14 slides down synchronously, thereby effectively dispersing the impact force generated.

[0029] The working principle of the above implementation is as follows:

[0030] The operation steps are as follows:

[0031] First, after the flaw detection mechanism 3 and the pin detection mechanism 4 have inspected each ball pin in the middle of the placement frame 2, the ball pin can be transported downward through the rectangular hole 5 to the top of the right-angle plates 8 on both sides. The ball pin falls on the top of each rubber column 9 and is buffered and protected. After the transport is completed, the electric telescopic rods 6 on both sides are operated to push the right-angle plates 8 to rotate downward relative to each other. Each ball pin can then roll down along each rubber column 9, buffering the impact force of the ball pin during the transport process, reducing surface and internal damage caused by falling or collision, adapting to ball pins of different shapes and sizes, ensuring their stability during the transport process, preventing tilting or rolling. The use of flexible materials can effectively absorb vibration and impact, reduce noise during the transport process, and the stable transport process can ensure the accurate position of the ball pin during inspection, which helps to improve the accuracy and reliability of inspection methods such as eddy current flaw detection.

[0032] The automated transfer mechanism enables rapid and continuous transfer, reducing manual intervention, improving production efficiency, and shortening the inspection cycle. After each ball pin slides down, it lands on the sponge plate 12. The flexible contact protects the ball pin. Under the pressure of the weight of the ball pin, the sponge plate 12 slides down, and the downward force acts on the return spring 17, causing it to deform and the pin 16 to slide down. As the pin 16 moves, the hollow columns 13 on both sides rotate downward, causing the connecting rod 14 to slide down synchronously. This effectively disperses the impact force. The flexible collection mechanism simplifies the operation process, reduces the labor intensity of workers, and improves operational safety.
