Description

Technical Field

[0001] The present invention relates to the technical field of steel sleeve flaw detection and sorting, and particularly relates to an automatic steel sleeve flaw detection and sorting device. Background Art

[0002] Steel sleeves are generally hollow cylinders, and their inner and outer diameters have different size specifications according to specific usage requirements, and the length also varies depending on the application scenario. Steel sleeves have a certain wall thickness to ensure that they can withstand corresponding pressures and stresses during use. Their inner and outer surfaces usually need to be precision machined to achieve high dimensional accuracy and surface finish to meet the mating requirements with other components.

[0003] In industries such as mechanical manufacturing, steel sleeves, as commonly used components, their quality directly affects the performance and reliability of the entire mechanical system. During the production process of steel sleeves, internal or surface defects such as cracks, pores, and slag inclusions may occur. If these defects cannot be detected in time, serious safety problems will occur during subsequent use.

[0004] Currently, when detecting steel sleeves for flaws, first, workers need to fix the outer ring of the steel sleeve, and then detect the inner ring of the steel sleeve for flaws. Then, manually switch the fixing position, fix the inner ring of the steel sleeve, and then detect the outer ring of the steel sleeve for flaws, so as to achieve a full range of flaw detection for the steel sleeve. However, this fixing method is a bit cumbersome, which will reduce the overall detection efficiency. Moreover, currently, after flaw detection, the steel sleeves are directly divided into qualified products or unqualified products, and cannot be marked with grades according to the reasons for the unqualified steel sleeves, which is not conducive to the development of subsequent work. Therefore, it is necessary to design an automatic steel sleeve flaw detection and sorting device to solve the above problems.

[0050] First embodiment:

[0051] Please refer to Figures 1 - 8 , in the first embodiment of the present invention, an automatic flaw detection and sorting device for steel sleeves includes:

The sealing rod 416 is slidably and sealingly installed on the connecting cylinder 415. It should be noted that a sealing washer is embedded on the sealing rod 416, so as to ensure the sliding and sealing fit between the sealing rod 416 and the connecting cylinder 415. One sealing rod 416 is matched with one connecting cylinder 415, and the number of connecting cylinders 415 and sealing rods 416 can be configured in multiple;

[0056] The top of the sealing rod 416 is fixedly connected to the moving disc 414. The round box 417 is fixedly installed at the bottom of the hollow disc 409. The hollow round seat 420 is fixedly installed on the round box 417. The air charging pipe 419 is fixedly connected to the hollow round seat 420. The connecting pipe 421 is fixedly installed between the hollow round seat 420 and the second airbag 422. The moving plate 423 is fixedly connected to the second airbag 422. The bidirectional lead screw 425 is rotatably installed on the round box 417. The bidirectional lead screw 425 is threadedly connected to the moving plate 423. The gear 426 is fixedly sleeved on the outside of the bidirectional lead screw 425;

[0057] The flaw detection mechanism 4 further includes a top plate 401, a sleeve plate 402, a first power motor 403, a screw rod 404, a hydraulic cylinder 405, a frame body 406, a second power motor 407, a docking hole 418, a bottom groove 424 and a moving hole 427. The top plate 401 is fixedly installed on the top of the first frame 2. The sleeve plate 402 is slidably sleeved on the outside of the first frame 2. The first power motor 403 is fixedly installed on the top plate 401. The output end of the first power motor 403 is fixedly connected to the screw rod 404. The screw rod 404 is rotatably installed on the top plate 401. The screw rod 404 is threadedly connected to the sleeve plate 402. The hydraulic cylinder 405 is fixedly installed at the bottom of the sleeve plate 402. The hydraulic rod of the hydraulic cylinder 405 is fixedly connected to the frame body 406. The second power motor 407 is fixedly installed on the frame body 406. The output end of the second power motor 407 is fixedly connected to the rotating shaft 408. The docking hole 418 is opened at the bottom of the round box 417. The bottom groove 424 is opened at the bottom of the round box 417. The moving hole 427 is opened on the top inner wall of the bottom groove 424. The moving plate 423 is horizontally slidably installed in the moving hole 427.

[0058] In this embodiment, to ensure the normal flow of air, the air filling pipe 419 is connected to the inside of the first airbag 410 and the hollow circular seat 420. The connecting cylinder 415 is connected to the inside of the air filling pipe 419. The connecting pipe 421 is connected to the inside of the hollow circular seat 420 and the second airbag 422. A through hole is formed at the bottom of the hollow disc 409, and the top of the hollow circular seat 420 penetrates through the through hole.

[0059] In this embodiment, to facilitate the clamping and fixing of the inner ring of the steel sleeve 11 and facilitate the subsequent release of the clamping and fixing, the outer side of the first airbag 410 abuts against the steel sleeve 11. Both the first airbag 410 and the second airbag 422 are non-elastic airbags. A non-elastic airbag refers to an airbag structure that does not undergo obvious elastic deformation or has limited elastic deformation like a common elastic airbag when inflated or subjected to external forces. It usually relies on the gas or other media filled inside to provide functions such as support, buffering, or isolation, but it is relatively stable in terms of morphological changes and will not expand or contract significantly due to pressure changes or external forces.

[0060] In this embodiment:

[0061] Place the steel sleeve 11 on the outer side of the first airbag 410. Start the cylinder 413. The cylinder 413 drives the moving plate 414 to move downward. The moving plate 414 drives the sealing rod 416 to move downward. When the sealing rod 416 moves downward, the air in the connecting cylinder 415 can be introduced into the air filling pipe 419. Then the air enters the first airbag 410 through the air filling pipe 419, causing the first airbag 410 to expand. The expanded first airbag 410 can tightly press against the inner ring of the steel sleeve 11, thus limiting and fixing the steel sleeve 11. Start the hydraulic cylinder 405, which can drive the limited and fixed steel sleeve 11 to move vertically. Start the second power motor 407, which can drive the limited and fixed steel sleeve 11 to rotate. Start the first power motor 403, which can drive the limited and fixed steel sleeve 11 to move horizontally. At this time, it can cooperate with the ultrasonic flaw detection probe 505 on the detection and sorting mechanism 5 to complete the flaw detection of the outer ring of the steel sleeve 11;

[0062] During the docking process through the docking hole 418 with the docking block 507 on the lower detection and sorting mechanism 5, the toothed plate 508 on the docking block 507 meshes with the gear 426, which can cause the bidirectional lead screw 425 to rotate. When the bidirectional lead screw 425 rotates, the two moving plates 423 can move away from each other. When the moving plates 423 move, they can unfold the second airbag 422. At this time, a part of the air in the first airbag 410 can be separated and enter the second airbag 422. In this way, the first airbag 410 can contract accordingly. At this time, the limit on the steel sleeve 11 can be released, and the docking between the docking block 507 and the docking hole 418 can be achieved. Then, the flaw detection of the inner ring of the steel sleeve 11 can be carried out. Only manual placement is required, and subsequent operations do not require manual control at all. The flaw detection of the outer and inner rings of the steel sleeve 11 can be realized, improving the overall detection efficiency.

[0063] Compared with the related technologies, an automatic flaw detection, inspection and sorting device for steel sleeves provided by the present invention has the following beneficial effects:

[0064] After the steel sleeve 11 is placed, it only needs to automatically lock the inner ring of the steel sleeve 11. At this time, flaw detection can be performed on the outer ring of the steel sleeve 11. Subsequently, it is docked with the detection and sorting mechanism 5. During the docking process, the locking of the inner ring of the steel sleeve 11 can be automatically released, and then flaw detection can be performed on the inner ring of the steel sleeve 11.

[0065] Second Embodiment:

[0066] Please refer to Figure 1 、 Figure 2 、 Figure 9 、 Figure 10 and Figure 11 In the second embodiment of the present invention, an automatic flaw detection, inspection and sorting device for steel sleeves further includes a detection and sorting mechanism 5 provided on the machine table 1. The detection and sorting mechanism 5 includes a main frame 501, a support frame 502, a circular ring seat 503, a vertical shaft 504, an ultrasonic flaw detection probe one 505, an ultrasonic flaw detection probe two 506, a docking block 507 and a toothed plate 508. The main frame 501 is fixedly installed on the top of the machine table 1, the support frame 502 is fixedly installed on the main frame 501, the circular ring seat 503 is fixedly installed on the support frame 502, the vertical shaft 504 is rotatably installed on the main frame 501, the ultrasonic flaw detection probe one 505 is fixedly installed on the main frame 501, the ultrasonic flaw detection probe two 506 is fixedly installed on the vertical shaft 504, the docking block 507 is fixedly installed on the top of the vertical shaft 504, and the toothed plate 508 is fixedly installed on the top of the docking block 507.

[0067] In this embodiment, in order to ensure the stability of the vertical shaft 504 at rest and ensure a normal docking process, a damping pad one 509 is fixedly provided on the main frame 501, and the vertical shaft 504 abuts against the inner side of the damping pad one 509.

[0068] The ultrasonic flaw detection probe one 505 and the ultrasonic flaw detection probe two 506 can detect tiny cracks on the surface of the steel sleeve 11 that are difficult to detect with the naked eye. For example, during the forging process, if the forging process is improper, forging cracks may appear on the surface of the steel sleeve 11, and ultrasonic flaw detection can timely detect the existence, position, length and other information of these cracks.

[0069] During the casting process of the steel sleeve 11, gas in the molten metal may not be discharged in time, which may form pores inside the steel sleeve 11. The ultrasonic flaw detection probe 505 and the ultrasonic flaw detection probe 506 can detect the pore defects inside the steel sleeve 11. When ultrasonic waves encounter pores, reflection and scattering will occur at the interface between the pores and the metal. The characteristics of the reflected waves are related to the size, shape, and quantity of the pores. By analyzing the reflected waves, the presence of pores and their approximate sizes and positions can be determined.

[0070] During the production process of the steel sleeve 11, some non-metallic inclusions may be mixed in to form slag inclusions. The ultrasonic flaw detection probe 505 and the ultrasonic flaw detection probe 506 can detect these internal slag inclusions. The acoustic properties of the slag inclusions are different from those of the matrix of the steel sleeve 11. When ultrasonic waves encounter the slag inclusions, reflection and refraction will occur. The presence, size, and position of the slag inclusions can be judged according to the situation of the reflected waves. For example, during the steelmaking process, if the slag is not completely removed, slag inclusions may be formed in the steel sleeve 11, and ultrasonic flaw detection can detect such defects.

[0071] In this embodiment:

[0072] After the steel sleeve 11 is clamped and fixed on the inner ring, start the second power motor 407, which can drive the steel sleeve 11 with the fixed inner ring to rotate. At this time, the first ultrasonic flaw detection probe 505 can perform flaw detection on the outer ring of the rotating steel sleeve 11. After the flaw detection of the outer ring is completed, start the hydraulic cylinder 405 to drive the clamped and fixed steel sleeve 11 to move downward. First, make the toothed plate 508 pass through the docking hole 418 and engage with the gear 426, which will then drive the gear 426 to rotate. When the gear 426 rotates, it will drive the bidirectional lead screw 425 to rotate. When the bidirectional lead screw 425 rotates, it will cause the two moving plates 423 to move away from each other. When the moving plate 423 moves, it can expand the second airbag 422. At this time, a part of the air in the first airbag 410 can be separated and enter the second airbag 422. In this way, the first airbag 410 can contract accordingly. At this time, the limit on the steel sleeve 11 can be released. After the limit is released, the steel sleeve 11 will fall into the circular ring seat 503. The bottom of the steel sleeve 11 is supported by the support frame 502 until the docking block 507 is inserted into the docking hole 418. At this time, start the second power motor 407. Due to the docking of the docking block 507 and the docking hole 418, the vertical shaft 504 will rotate, and the vertical shaft 504 will drive the second ultrasonic flaw detection probe 506 to rotate. The second ultrasonic flaw detection probe 506 will perform flaw detection on the inner ring of the steel sleeve 11. After the detection is completed, start the hydraulic cylinder 405 to move the hollow disc 409 upward. During the upward movement of the hollow disc 409, the two moving plates 423 move towards each other. In this way, the second airbag 422 can be squeezed. At this time, a part of the air in the second airbag 422 will enter the first airbag 410, causing the first airbag 410 to expand. After expansion, the first airbag 410 continues to clamp and fix the inner ring of the steel sleeve 11. However, at this time, the clamping position of the inner ring of the steel sleeve 11 is at a position above. Then lift the steel sleeve 11 upward, and sort and mark the steel sleeve 11 through the sorting and marking mechanism 6 above the steel sleeve 11 according to the detection results.

It should be noted that the slider is provided with protruding heads on both sides, and there are protruding grooves in the track groove 604, which are not shown in the figure, so that the slider can move stably in the track groove 604;

[0075] The bottom of the slider is fixedly connected to the fitting 605. The slot 606 is formed at the bottom of the fitting 605. The abutting plate 607 is fixedly installed on the fitting 605. The top of the fitting 605 abuts against the bottom of the side plate 603. The protective shell 608 is fixedly installed at the bottom of the cross frame. It should be noted that the purpose of setting the protective shell 608 is to prevent touching the fitting 605. Accidentally touching the fitting 605 is likely to release the limit on the marking pen 601.

[0076] In this embodiment, in order to ensure the stability of the slider in a static state and to improve the stability of the marking pen 601 after being clamped, a second damping pad is fixedly provided in the track groove 604, and the top of the slider abuts against the second damping pad. A square hole is formed in the inner wall of the top of the pen groove, and the square plate 602 is clamped in the square hole.

[0077] In this embodiment, in order to facilitate the sorting of the steel sleeves 11, a control panel 7 is fixedly provided on the second frame 3. A qualified product falling hole 8 and an unqualified product falling hole 9 are formed at the top of the machine table 1. Conveyor belts 10 are provided below the qualified product falling hole 8 and the unqualified product falling hole 9. It should be noted that the conveyor belt 10 is connected to an external conveying table at the rear, which is not shown in the figure.

[0078] In this embodiment:

[0079] Start the hydraulic cylinder 405 to lift the detected steel sleeve 11 upward. If the steel sleeve 11 is detected to be qualified, no marking is performed, and start the first power motor 403 to move the steel sleeve 11 to above the qualified product falling hole 8. Start the hydraulic cylinder 405 to slowly lower the steel sleeve 11. When it reaches an appropriate height, start the air cylinder 413, and the first airbag 410 contracts to release the limit on the steel sleeve 11, so that the steel sleeve 11 falls into the qualified product falling hole 8 and is conveyed outward through the conveyor belt 10 in the qualified product falling hole 8;

[0080] If the steel sleeve 11 fails the inspection, it is marked. At this time, the steel sleeve 11 is lifted by the hydraulic cylinder 405 to the position corresponding to the tip of the marking pen 601. If only slag inclusions are detected in the steel sleeve 11, the first power motor 403 is started at this time, so that the steel sleeve 11 moves to the right. During the rightward movement of the steel sleeve 11, the marking pen 601 makes a horizontal mark on the steel sleeve 11, and the result is as Figure 14 shown. Then the steel sleeve 11 is moved above the nonconforming product falling hole 9, the hydraulic cylinder 405 is started, and the steel sleeve 11 is slowly lowered. When it reaches the appropriate height, the air cylinder 413 is started, and the first airbag 410 contracts to release the limit on the steel sleeve 11, so that the steel sleeve 11 falls into the nonconforming product falling hole 9 and is conveyed outward through the conveyor belt 10 in the nonconforming product falling hole 9;

[0081] If pores are detected in the steel sleeve 11, the second power motor 407 is started at this time, so that the steel sleeve 11 rotates clockwise by a certain position and then rotates counterclockwise back. Then the first power motor 403 is started, so that the steel sleeve 11 moves to the right. During the rotation and rightward movement of the steel sleeve 11, the marking pen 601 makes a horizontal mark on the steel sleeve 11, and the result is as Figure 15 shown. Then the steel sleeve 11 is moved above the nonconforming product falling hole 9, the hydraulic cylinder 405 is started, and the steel sleeve 11 is slowly lowered. When it reaches the appropriate height, the air cylinder 413 is started, and the first airbag 410 contracts to release the limit on the steel sleeve 11, so that the steel sleeve 11 falls into the nonconforming product falling hole 9 and is conveyed outward through the conveyor belt 10 in the nonconforming product falling hole 9;

[0082] If cracks are detected in the steel sleeve 11, the second power motor 407 is started at this time, so that the steel sleeve 11 rotates clockwise by a certain position and then rotates counterclockwise by a certain position, and finally returns to the original position. Then the first power motor 403 is started, so that the steel sleeve 11 moves to the right. During the rotation and rightward movement of the steel sleeve 11, the marking pen 601 makes a horizontal mark on the steel sleeve 11, and the result is as Figure 16 shown. Then the steel sleeve 11 is moved above the nonconforming product falling hole 9, the hydraulic cylinder 405 is started, and the steel sleeve 11 is slowly lowered. When it reaches the appropriate height, the air cylinder 413 is started, and the first airbag 410 contracts to release the limit on the steel sleeve 11, so that the steel sleeve 11 falls into the nonconforming product falling hole 9 and is conveyed outward through the conveyor belt 10 in the nonconforming product falling hole 9;

[0083] Through different marking methods, the grading marks can be made according to the reasons for the nonconformity of the steel sleeve 11, which is conducive to the development of subsequent work;

[0084] Moreover, when the ink volume of the marker pen 601 is low and the steel sleeve 11 is not fixed, the hydraulic cylinder 405 is started, so that the insertion plate 411 moves upward. After the insertion plate 411 moves upward, it will be inserted into the slot 606 and dock with the fitting 605. Then, the power motor two 407 is started, which can make the insertion plate 411 rotate slightly. When the insertion plate 411 rotates, it can drive the fitting 605 to rotate slightly. In this way, the slider can slide in the track groove 604. The track groove 604 is an arc-shaped structure, and the center is at the position of the rotating shaft 408. Therefore, the fitting 605 can rotate slightly along with the insertion plate 411. When the fitting 605 rotates, it will drive the abutting plate 607 to rotate, so that the abutting plate 607 is separated from the side plate 603, and the limit on the marker pen 601 is released. At this time, pulling down the marker pen 601 can remove the marker pen 601 for replacement.
