Description

Technical Field

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

[0002] The steel sleeve is generally a hollow cylinder, and its inner and outer diameters have different size specifications according to specific use requirements, and the length also varies according to the application scenario. The steel sleeve has a certain wall thickness to ensure that it can withstand the corresponding pressure and stress during use. Its inner and outer surfaces usually need to be precisely processed to achieve high dimensional accuracy and surface finish to meet the requirements of matching with other parts.

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

[0004] At present, when performing flaw detection on a steel sleeve, a worker is first required to fix the outer ring of the steel sleeve, and then perform flaw detection on the inner ring of the steel sleeve, and then manually switch the fixed position to fix the inner ring of the steel sleeve, and then perform flaw detection on the outer ring of the steel sleeve, so as to achieve all-round flaw detection of the steel sleeve. However, this fixing method is slightly cumbersome and will reduce the overall detection efficiency. Moreover, at present, after the flaw detection is completed, the steel sleeve is directly divided into qualified or unqualified products, and cannot be graded and marked according to the reasons for the failure of the steel sleeve, which is not conducive to the subsequent work. Therefore, it is necessary to design an automatic flaw detection and sorting device for steel sleeves to solve the above problems.

One sealing rod 416 is equipped with one connecting tube 415, and the number of connecting tubes 415 and sealing rods 416 can be configured in multiples; The top of the sealing rod 416 is fixedly connected to the moving disk 414, the round box 417 is fixedly installed on the bottom of the hollow round disk 409, the hollow round seat 420 is fixedly installed on the round box 417, the inflation tube 419 is fixedly connected to the hollow round seat 420, the connecting tube 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 screw rod 425 is rotatably installed on the round box 417, the bidirectional screw rod 425 is threadedly connected to the moving plate 423, and the gear 426 is fixedly sleeved on the outer side of the bidirectional screw rod 425; The flaw detection mechanism 4 also includes a top plate 401, a sleeve plate 402, a power motor 1 403, a screw 404, a hydraulic cylinder 405, a frame 406, a power motor 2 407, a docking hole 418, a bottom groove 424 and a moving hole 427. The top plate 401 is fixedly mounted on the top of the frame 1 2, the sleeve plate 402 is slidably sleeved on the outer side of the frame 1 2, the power motor 1 403 is fixedly mounted on the top plate 401, the output end of the power motor 1 403 is fixedly connected to the screw 404, the screw 404 is rotatably mounted on the top plate 401, and the screw 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 406, the power motor 407 is fixedly installed on the frame 406, the output end of the 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, and the moving plate 423 is horizontally slidably installed in the moving hole 427.

[0042] In this embodiment, in order to ensure the normal flow of air, the inflation tube 419 is connected with the interior of airbag 1 410 and the hollow round seat 420, the connecting tube 415 is connected with the interior of the inflation tube 419, the connecting tube 421 is connected with the interior of the hollow round seat 420 and the airbag 2 422, a through hole is opened at the bottom of the hollow disc 409, and the through hole runs through the top of the hollow round seat 420.

[0043] In this embodiment, in order to facilitate the clamping and fixing of the inner ring of the steel sleeve 11 and the subsequent release of the clamping and fixing, the outer side of the airbag 410 is abutted against the steel sleeve 11. The airbag 410 and the airbag 422 are both 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 an ordinary elastic airbag when inflated or subjected to external force. It usually relies on the gas or other media filled inside to provide support, cushioning or isolation functions, but is relatively stable in morphological changes and will not expand or contract significantly due to pressure changes or external forces.

[0044] In this embodiment: The steel sleeve 11 is placed on the outside of the airbag 410, and the cylinder 413 is started. The cylinder 413 drives the movable plate 414 to move downward, and the movable plate 414 drives the sealing rod 416 to move downward. When the sealing rod 416 moves downward, the air in the connecting tube 415 can be introduced into the inflation tube 419, and then the air enters the airbag 410 through the inflation tube 419, so that the airbag 410 expands. The expanded airbag 410 can press the inner ring of the steel sleeve 11 tightly, so that the steel sleeve 11 is limited and fixed. The hydraulic cylinder 405 is started to drive the steel sleeve 11 to move vertically after the limit is fixed. The power motor 407 is started to drive the steel sleeve 11 to rotate after the limit is fixed. The power motor 403 is started to drive the steel sleeve 11 to move horizontally after the limit is fixed. At this time, the ultrasonic flaw detection probe 505 on the detection and sorting mechanism 5 can be cooperated to complete the flaw detection of the outer ring of the steel sleeve 11. In the process of docking with the docking block 507 on the lower detection and sorting mechanism 5 through the docking hole 418, the tooth plate 508 on the docking block 507 is meshed with the gear 426, which can make the bidirectional screw rod 425 rotate. When the bidirectional screw rod 425 rotates, the two movable plates 423 can move away from each other. When the movable plate 423 moves, the airbag 2 422 can be deployed. At this time, a part of the air in the airbag 1 410 can be separated and enter the airbag 2 422, so that the airbag 1 410 can shrink accordingly. At this time, the limit on the steel sleeve 11 can be released, and the docking of 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 is carried out. It only needs manual placement, and no manual operation is required subsequently. The flaw detection of the outer ring and the inner ring of the steel sleeve 11 can be achieved, thereby improving the overall detection efficiency.

[0045] Compared with the related art, the steel sleeve automatic flaw detection and sorting device provided by the present invention has the following beneficial effects: It is only necessary to place the steel sleeve 11 and automatically lock the inner ring of the steel sleeve 11. At this time, the outer ring of the steel sleeve 11 can be inspected by flaw detection, and then 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 the inner ring of the steel sleeve 11 can be inspected by flaw detection.

[0046] Second embodiment: Please refer to Figure 1 , Figure 2 , Fig. 9 , Fig.10 and Fig.11 In the second embodiment of the present invention, a steel sleeve automatic flaw detection and sorting device also includes: a detection and sorting mechanism 5 arranged on the machine platform 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 1 505, an ultrasonic flaw detection probe 2 506, a docking block 507 and a tooth plate 508, the main frame 501 is fixedly installed on the top of the machine platform 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 1 505 is fixedly installed on the main frame 501, the ultrasonic flaw detection probe 2 506 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 tooth plate 508 is fixedly installed on the top of the docking block 507.

[0047] In this embodiment, in order to ensure the stability of the vertical shaft 504 when stationary and to ensure a normal docking process, a damping pad 509 is fixedly provided on the main frame 501 , and the vertical shaft 504 abuts against the inner side of the damping pad 509 .

[0048] Ultrasonic flaw detection probe 1 505 and ultrasonic flaw detection probe 2 506 can detect tiny cracks that are difficult to detect with naked eyes on the surface of the steel sleeve 11. 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 promptly detect the existence of these cracks and their location, length and other information.

[0049] During the casting process of the steel sleeve 11, pores may be formed inside the steel sleeve 11 due to the failure to discharge the gas in the molten metal in time. Ultrasonic flaw detection probe 1 505 and ultrasonic flaw detection probe 2 506 can detect pore defects inside the steel sleeve 11. When the ultrasonic wave encounters pores, it will be reflected and scattered at the interface between the pores and the metal. The characteristics of the reflected wave are related to the size, shape and number of the pores. By analyzing the reflected wave, the existence, approximate size and position of the pores can be determined.

[0050] During the production process of the steel sleeve 11, some non-metallic inclusions may be mixed in, forming slag inclusions. Ultrasonic flaw detection probe 1 505 and ultrasonic flaw detection probe 2 506 can detect these internal slag inclusions. Slag inclusions have different acoustic properties from the steel sleeve 11 matrix. When ultrasonic waves encounter slag inclusions, they will be reflected and refracted. The existence, size and location of slag inclusions can be determined based on 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 this defect.

[0051] In this embodiment: After the steel sleeve 11 is clamped and fixed in the inner ring, the power motor 2 407 is started to drive the steel sleeve 11 with the inner ring fixed to rotate. At this time, the ultrasonic flaw detection probe 1 505 can perform flaw detection on the outer ring of the rotating steel sleeve 11. After the flaw detection of the outer ring is completed, the hydraulic cylinder 405 is started to drive the clamped steel sleeve 11 to move downward, firstly, the tooth plate 508 passes through the docking hole 418 and meshes with the gear 426, which will drive the gear 426 to rotate. When the gear 426 rotates, The two-way screw rod 425 will be driven to rotate. When the two-way screw rod 425 rotates, the two moving plates 423 will move away from each other. When the moving plate 423 moves, the airbag 2 422 can be deployed. At this time, a part of the air in the airbag 1 410 can be separated and enter the airbag 2 422. In this way, the airbag 1 410 can be contracted accordingly. At this time, the limit of the steel sleeve 11 can be released. After the limit is released, the steel sleeve 11 will fall into the annular seat 503. The bottom of the steel sleeve 11 passes through the support frame 50 2 for support until the docking block 507 is inserted into the docking hole 418. At this time, the power motor 2 407 is started. Due to the docking of the docking block 507 and the docking hole 418, the vertical shaft 504 is rotated, and the vertical shaft 504 drives the ultrasonic flaw detection probe 2 506 to rotate. The ultrasonic flaw detection probe 2 506 performs flaw detection on the inner ring of the steel sleeve 11. After the detection is completed, the hydraulic cylinder 405 is started to move the hollow disc 409 upward. During the upward movement of the hollow disc 409, the two movable plates 4 23 move in the direction of approaching each other, so that the airbag 2 422 can be squeezed, and at this time, a part of the air in the airbag 2 422 will enter the airbag 1 410, so that the airbag 1 410 will expand, and the expanded airbag 1 410 will continue to clamp and fix the inner ring of the steel sleeve 11, but at this time, the clamping position of the inner ring of the steel sleeve 11 is at an upper position, and then the steel sleeve 11 is lifted up, and the steel sleeve 11 is sorted and marked by the sorting and marking mechanism 6 above the steel sleeve 11 according to the detection result.

[0052] Third embodiment: Please refer to Figure 1 , Figure 2 , Fig.12 , Fig.13, Fig.14 , Fig.15 and Fig.16 In the third embodiment of the present invention, a steel sleeve automatic flaw detection and sorting device further includes: a sorting marking mechanism 6 arranged on the frame 2 3, the sorting marking mechanism 6 includes a cross frame, a marking pen 601, a square plate 602, a side plate 603, a track groove 604, a matching piece 605, a slot 606, an abutment plate 607 and a protective shell 608, the cross frame is fixedly connected to the frame 2 3, a pen slot is provided at the bottom of the cross frame, the marking pen 601 is clamped with the pen slot, the square plate 602 is fixedly installed on the top of the marking pen 601, the square plate 602 is clamped with the cross frame, the side plate 603 is fixedly installed on the outside of the marking pen 601, the track groove 604 is provided at the bottom of the cross frame, and a slider is slidably connected in the track groove. It should be noted that extension heads are provided on both sides of the slider, and an extension groove is provided in the track groove 604, which is not shown in the figure, so that the slider can move stably in the track groove 604; The bottom of the slider is fixedly connected to the mating piece 605, the slot 606 is opened at the bottom of the mating piece 605, the abutment plate 607 is fixedly installed on the mating piece 605, the top of the mating piece 605 abuts against the bottom of the side plate 603, and 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 mating piece 605. Accidentally touching the mating piece 605 can easily release the limit on the marking pen 601.
