A fifth damping spring is arranged on the outside of the auxiliary plate and is sleeved on the cross bars. The position of the auxiliary plate corresponds to the position of the opening, and the sliding ball is located on the top of the auxiliary plate and slides.

[0014] Compared with the prior art, it has the following beneficial effects:

[0015] Through the detection components set up, defects on the surface of the shell body can be detected in real time. Once the sliding ball contacts the concave or convex part of the shell body, it will immediately trigger the corresponding circuit through mechanical transmission to achieve instant feedback. This immediacy is helpful to quickly identify and handle unqualified products in the production process and reduce the outflow of defective products; through the contact between the connecting copper sheet and the first fixed copper sheet or the second fixed copper sheet, the defect type (concave or convex part) of the shell body can be accurately judged. This accuracy is helpful for subsequent quality analysis and improvement work and improves product quality stability; the lighting of the first alarm light and the second alarm light provides intuitive visual feedback, so that the inspection personnel can quickly identify the defect location and type of the shell body. This intuitive alarm method reduces the possibility of misjudgment and missed judgment and improves the detection efficiency.

[0016] By turning on the cylinder to drive the movement of the mounting seat and the moving seat, the position of the moving rod and the sliding ball can be flexibly adjusted, and then the distance between adjacent sliding beads can be adjusted. This adjustment mechanism enables the detection component to adapt to shell bodies of different sizes and shapes, and to detect defects at different positions on the surface of the shell body, thereby improving the flexibility and versatility of detection. By precisely adjusting the position and spacing of the sliding beads, it can be ensured that the detection component can accurately cover the entire surface of the shell body, especially those edges and corners that are difficult to detect, which helps to improve the precision and accuracy of detection and reduce the possibility of missed detection and false detection.

[0017] When the auxiliary plate moves to one side to the farthest distance, that is, after the detection of the shell body is completed, through a series of mechanical transmissions, the pushing block can push the movable block to move inward and compress the fourth damping spring, so that the clamping rod clamps and limits the limit block. This automatic clamping and fixing mechanism ensures the stable position of key components such as the moving rod, sliding ball, and connecting copper sheet after the detection is completed, avoiding misoperation or damage caused by position changes; in the clamping limit state, the connecting copper sheet does not contact the first fixed copper sheet or the second fixed copper sheet, thereby ensuring that the first alarm light and the second alarm light will not alarm due to false triggering, which improves the accuracy and reliability of detection and avoids production interruptions or waste of resources due to false alarms.

[0018] When the surface of the shell body is uneven, the moving rod, sliding ball, limit block and V-block will move accordingly, pushing the guide column and sealing plate to move to one side of the hopper. The more serious the unevenness, the larger the moving range of the V-block, and the farther the sealing plate is pushed to move, the larger the contact area between the discharge hole and the discharge hopper and the input end of the pump body, and the spray volume of the marked material increases accordingly. This intelligent adaptability ensures the accuracy and effectiveness of the marking; by quickly identifying and processing unqualified products, the mechanism helps to improve production efficiency and product quality. Once defects appear on the surface of the shell body, the marking material will be sprayed out immediately for marking, allowing production personnel to quickly discover and take corresponding measures. The mechanism is implemented in a way that reduces the outflow of defective products and improves the qualified rate of products. When the mechanism moves on the flat surface of the shell body, the guide column is always located between the V-blocks, the discharge holes are located on both sides of the discharge hopper, and the sealing plate can seal the inside of the discharge hopper to prevent the marking material from being extracted by the pump body. This design avoids unnecessary waste of marking material on the flat surface and reduces production costs. The spraying amount of marking material changes with the change of the concave and convex degree of the shell body surface, which provides intuitive feedback for production personnel. By observing the spraying of marking material, production personnel can judge the concave and convex degree of the shell body, and thus take corresponding adjustment measures to ensure the stability of product quality.

This design enables the detection component 5 to effectively detect the concave and convex defects on the surface of the shell main body 3, thereby ensuring the quality of the shell main body 3;

[0033] At the top of the adjacent moving seats 52, they are connected to the first linkage rod 53 and the second linkage rod 54 by rotation. The adjacent first linkage rods 53 and the second linkage rods 54 are rotationally connected to each other to form a linkage system. Among these moving seats 52, one side is fixedly connected to the mounting seat 55. A cylinder 56 mounted on the fixing frame 4 is arranged on one side of the mounting seat 55, and a positioning rod 57 is arranged on the top of the moving seat 52 on the other side. The positioning rod 57 is connected to the fixing frame 4, which can ensure the stability of the entire device. When the positions of the moving rod 513 and the sliding ball 514 are adjusted, the cylinder 56 can be turned on to drive the movement of the mounting seat 55. As the mounting seat 55 moves, it will push the moving seat 52 to move accordingly. The moving seat 52, in cooperation with the first linkage rod 53 and the second linkage rod 54, drives the remaining moving seats 52 to move, thereby driving the first connecting rod 511, the moving rod 513, and the sliding ball 514 to move together. In this way, the distance between adjacent sliding balls 514 can be adjusted, and defects at different positions on the surface of the shell body 3 can be detected and processed;

[0034] A rectangular groove 59 is provided on the surface of the fixed seat 58, and the bottom of the first connecting rod 511 is installed in the rectangular groove 59 by sliding horizontally through the slide seat 510. The surface of the mobile rod 513 is fixedly connected to the limit block 520. A second damping spring 521 sleeved on the mobile rod 513 is provided between the limit block 520 and the slide seat 510. Under the elastic force of the second damping spring 521, the mobile rod 513 and the sliding ball 514 can be pushed to move downward, so that the sliding ball 514 always keeps in contact with the surface of the shell body 3, so as to facilitate the subsequent defect detection and processing;

[0035] The inner wall of the fixed seat 58 is provided with movable grooves 533 on both sides, and two movable blocks 534 are slidably connected to the inner wall of the movable groove 533. A fourth damping spring 535 is arranged between the two movable blocks 534. Clamping rods 539 are fixedly connected to the surfaces of the movable blocks 534 on both sides. The two clamping rods 539 are located on both sides of the moving rod 513, and the clamping rods 539 on the two movable blocks 534 are respectively located at the upper and lower ends of the limit block 520. The outer end of the movable block 534 is provided with a sliding rod 539 slidably mounted on the fixed seat 58. 36, a push block 537 is fixedly connected to the inner side end of one side of the two sliding rods 536, and the other side of the two sliding rods 536 is fixedly connected by a second connecting rod 538, and the second connecting rod 538 is connected to the auxiliary plate 6. When the auxiliary plate 6 moves to one side, the auxiliary plate 6 can drive the two sliding rods 536 to move synchronously through the second connecting rod 538, so that the sliding rod 536 drives the push block 537 to move synchronously. When the auxiliary plate 6 moves to one side to the farthest distance, that is, after the detection of the shell body 3 is completed, the push block 537 The movable block 534 is moved to the position so that the push block 537 pushes the two movable blocks 534 to move inward and compresses the fourth damping spring 535, so that the clamping rods 539 on the two movable blocks 534 move toward the side of the limit block 520, so that the clamping rods 539 on both sides clamp and limit the limit block 520, thereby fixing the position of the movable rod 513, the sliding ball 514, and the connecting copper sheet 515. At this time, after the detection of the shell body 3 is completed, the shell body 3 is moved out, and this period of time makes the connecting copper sheet 515 does not contact the first fixed copper sheet 516 or the second fixed copper sheet 517, so that the first warning light 518 and the second warning light 519 will not alarm. When the auxiliary plate 6 is reset under the elastic force of the fifth damping spring 62, it can drive the second connecting rod 538, the sliding rod 536, and the pushing block 537 to move and reset. At the same time, the movable block 534 and the clamping rod 539 are moved and reset under the elastic force of the fourth damping spring 535, so that the clamping rod 539 no longer clamps and limits the limit block 520.

[0036] At one end of the limit block 520, it is fixedly connected to a V-shaped block 523. A hopper 524 fixedly installed on the moving seat 52 is set on one side of the V-shaped block 523. A discharge hopper 525 is set inside the hopper 524. A sealing plate 526 that is sealingly slidably installed on the hopper 524 is set at the bottom of the discharge hopper 525. Discharge holes 527 are opened on both sides of the sealing plate 526. A pump body 528 is set at the bottom of the sealing plate 526. The input end of the pump body 528 is connected to the two discharge holes 527 through a pipeline. A discharge pipe 529 is set at the output end of the pump body 528. The other end of the discharge pipe 529 corresponds to the bottom position of the moving rod 513. A guide column 530 is fixedly connected to the sealing plate 526 near the side of the V-shaped block 523. The guide column 530 slides in contact with the outer wall of the V-shaped block 523. A convex plate 531 is fixedly connected to the top of the guide column 530, and a third damping spring 532 is arranged between the convex plate 531 and the hopper 524. When a concave or convex part appears on the shell body 3, the moving rod 513, the sliding ball 514, the limit block 520, and the V-block 523 are driven to move downward or upward, and the V-block 523 pushes the guide column 530 and the sealing plate 526 to move toward the side of the hopper 524. At the same time, under the elastic force of the third damping spring 532, the guide column 530 always slides in contact with the outer wall of the V-block 523, so that the position of the discharge hole 527 of the discharge hopper 525 and the pump body 528 corresponds to each other, and the marking material in the hopper 524 and the discharge hopper 525 flows to the pump body 528 through the discharge hole 527. The marking material is drawn by the pump body 528, so that the marking material is sprayed out through the discharge pipe 529 to the surface defect of the shell body 3.

[0037] In an embodiment of the present invention, the first fixed copper sheet 516, the first wire, the first power supply, and the first alarm light 518 are connected in series by using the connecting copper sheet 515, or the second fixed copper sheet 517, the second wire, the second power supply, and the second alarm light 519 are connected in series by using the connecting copper sheet 515, so as to ensure that the first power supply and the second power supply can stably provide electric energy, so that the first alarm light 518 and the second alarm light 519 can smoothly perform alarm processing; through the alarm processing of the first alarm light 518 or the second alarm light 519, the defects on the surface of the shell body 3 can be effectively detected and processed, and through the alarm processing of the first alarm light 518 or the second alarm light 519, the defects on the surface of the shell body 3 can be effectively detected and processed. Accurately judge whether the defect of the shell body 3 is a concave part or a convex part; through the detection component 5, the surface defects of the shell body 3 can be detected in real time, because once the sliding ball 514 contacts the concave part or the convex part of the shell body 3, it will immediately trigger the corresponding circuit through mechanical transmission; through the contact between the connecting copper sheet 515 and the first fixed copper sheet 516 or the second fixed copper sheet 517, it can be accurately judged whether the defect type of the shell body 3 is a concave part or a convex part. The lighting of the first alarm light 518 and the second alarm light 519 provides intuitive visual feedback, so that the inspection personnel can quickly identify the defect position and type of the shell body 3. This intuitive alarm method reduces the possibility of misjudgment and missed judgment, and improves the detection efficiency;

[0038] When the position of the moving rod 513 and the sliding ball 514 needs to be adjusted, the mounting seat 55 is driven to move by turning on the air cylinder 56, so that the mounting seat 55 mobilizes the moving seat 52 to move, so that the moving seat 52 cooperates with the first linkage rod 53 and the second linkage rod 54 to drive the remaining moving seats 52 to move, and then the first connecting rod 511, the moving rod 513, and the sliding ball 514 can be driven to move, so that the distance between adjacent sliding balls 514 can be adjusted, so that defects at different positions on the surface of the shell body 3 can be detected and processed;

[0039] When the auxiliary plate 6 moves to one side, the auxiliary plate 6 can drive the two sliding rods 536 to move synchronously through the second connecting rod 538, so that the sliding rod 536 drives the pushing block 537 to move synchronously. When the auxiliary plate 6 moves to one side to the farthest distance, that is, after the detection of the shell body 3 is completed, the pushing block 537 moves to the position of the movable block 534, so that the pushing block 537 pushes the two movable blocks 534 to move inward and compresses the fourth damping spring 535, so that the clamping rods 539 on the two movable blocks 534 move to the side of the limit block 520, so that the clamping rods 539 on both sides clamp and limit the limit block 520, thereby moving the movable rod 513, the sliding ball 514, The position of the connecting copper sheet 515 is fixed. At this time, after the detection of the shell body 3 is completed, the shell body 3 is moved out. During this period of time, the connecting copper sheet 515 does not contact the first fixed copper sheet 516 or the second fixed copper sheet 517, so that the first alarm light 518 and the second alarm light 519 will not alarm; when the auxiliary plate 6 is reset under the elastic force of the fifth damping spring 62, it can drive the second connecting rod 538, the sliding rod 536, and the pushing block 537 to move and reset. At the same time, the movable block 534 and the clamping rod 539 are moved and reset under the elastic force of the fourth damping spring 535, so that the clamping rod 539 no longer clamps and limits the limit block 520;

[0040] When a concave or convex part appears on the shell body 3, the moving rod 513, the sliding ball 514, the limit block 520, and the V-shaped block 523 are driven to move downward or upward, and the V-shaped block 523 pushes the guide column 530 and the sealing plate 526 to move toward the side of the hopper 524. At the same time, under the elastic force of the third damping spring 532, the guide column 530 always slides in contact with the outer wall of the V-shaped block 523, so that the positions of the discharge hole 527, the discharge hopper 525, and the pump body 528 correspond to each other, and the marking material in the hopper 524 and the discharge hopper 525 flows to the pump body 528 through the discharge hole 527, and is extracted by the pump body 528, so that the marking material is sprayed through the discharge pipe 529 to the surface defects of the shell body 3. This helps to quickly identify and handle unqualified products during the production process, thereby improving production efficiency and product quality;

[0041] When the concave or convex part appears on the surface of the shell body 3, the more serious the concave or convex part is, the larger the movement range of the V-shaped block 523 is, and the longer the distance the sealing plate 526 can be pushed to move is, that is, the larger the contact area between the discharge hole 527 and the discharge hopper 525 and the input end of the pump body 528 is, that is, more marking materials pass through the discharge hole 527, and then by opening the pump body 528 and cooperating with the discharge hole 527, the marking materials in the hopper 524 and the discharge hopper 525 are extracted, and then transported through the discharge pipe 529 and sprayed out through the discharge pipe 529 for marking treatment. Moreover, since the concave or convex part is more serious, the larger the contact area between the discharge hole 527 and the discharge hopper 525 and the input end of the pump body 528 is, which means that more marking materials enter the pump body 528 through the discharge hole 527. This is because the increase in the contact area allows more marking materials to be The marking material will be sucked into the pump body 528. Therefore, when the surface unevenness of the shell body 3 is more serious, the amount of marking material entering the pump body 528 through the discharge hole 527 will increase accordingly due to the increase in contact area. Finally, the marking material is ejected through the discharge pipe 529 to mark the surface of the shell body 3. Since the amount of marking material extracted by the pump body 528 changes with the change of the unevenness of the surface of the shell body 3, the amount of marking material will also be adjusted accordingly; when the sliding ball 514 moves on the flat surface of the shell body 3, the guide column 530 is always located between the V-blocks 523. At this time, the two discharge holes 527 are located on both sides of the discharge hopper 525, so that the sealing plate 526 can seal the inside of the discharge hopper 525. At this time, the marking material will not be extracted by the pump body 528, that is, no marking material will appear on the surface of the flat shell body 3.

[0042] Embodiment 2: Combination Figure 2 As shown, on the basis of the first embodiment, a support frame 21 is fixedly installed at the bottom of the frame 1, a driving motor 22 is fixedly installed on the support frame 21, an output end of the driving motor 22 is rotatably connected to a connecting block 23 through a rotating shaft, a rotating rod 24 is slidably connected to the connecting block 23, one end of the rotating rod 24 is fixedly connected to a movable seat 25, a first damping spring 26 sleeved on the rotating rod 24 is arranged between the movable seat 25 and the connecting block 23, a fixed rod 210 is fixedly connected to the frame 1, a sleeve rod 29 is slidably connected to the fixed rod 210, a vertical rod 28 is fixedly connected to the bottom end of the sleeve rod 29, a lifting seat 27 is slidably connected to the vertical rod 28, and the movable seat 25 is rotatably installed on the lifting seat 27, a pushing rod 211 is arranged on the top of the lifting seat 27, an opening 212 is opened on one side of the material frame 2, and the specifications of the opening 212 are mutually adapted to the specifications of the shell body 3, the opening 212.

[0043] In the embodiment of the present invention, by starting the driving motor 22, the motor can drive the connecting block 23 to rotate synchronously. During the rotation process, the connecting block 23 will further drive the rotating rod 24 to rotate accordingly. The rotating rod 24 is connected to the movable seat 25. The movable seat 25 is driven by the rotating rod 24 to drive the lifting seat 27 to rotate. When the lifting seat 27 moves to the middle position, since the connecting block 23 rotates around the axis of the driving motor 22, the lifting seat 27 will slide along the vertical rod 28 during the movement to the middle position. In this process, the rotating rod 24 will also slide on the connecting block 23 and compress the first damping spring 26. As the lifting seat 27 moves, the pushing rod 211 located thereon will push the shell body 3 in the material frame 2 to move in the direction of the detection component 5, so that the detection component 5 can be externally exposed. The surface defects of the shell body 3 are detected and processed. When the lifting seat 27 moves away from the middle position, the elastic force of the first damping spring 26 will play a role, causing the lifting seat 27 to slide on the vertical rod 28. At the same time, the lifting seat 27 will cooperate with the vertical rod 28 to drive the sleeve rod 29 to slide back and forth on the fixed rod 210. Through this reciprocating control, the lifting seat 27 and the pushing rod 211 can achieve intermittent movement. This intermittent pushing method can ensure that the shell body 3 passes through the detection area at a certain speed and frequency, so that the detection component 5 can efficiently and continuously detect the shell body 3. This detection method not only improves the overall detection efficiency, but also because the shell body 3 passes through the detection area sequentially and orderly, the detection component 5 can fully detect each shell body 3, thereby reducing the possibility of missed detection or false detection and improving the quality of detection.

[0044] Example 3: Combination Figure 1 , Figure 3 As shown, on the basis of the second embodiment, a cross bar 61 is fixedly connected on both sides of the frame 1, and the auxiliary plate 6 is slidably installed on the cross bar 61, and a fifth damping spring 62 is provided on the outer side of the auxiliary plate 6 and is sleeved on the cross bar 61. The position of the auxiliary plate 6 corresponds to the position of the opening 212, and the sliding ball 514 is located on the top of the auxiliary plate 6 and slides.

[0045] In an embodiment of the present invention, the upper surface of the auxiliary plate 6 is located on the same horizontal line as the upper surface of the shell body 3 to be detected. When the shell body 3 pushes the auxiliary plate 6 forward, the auxiliary plate 6 will move to one side along the cross bar 61 and compress the fifth damping spring 62 in the process. The function of the fifth damping spring 62 is to help the cross bar 61 return to its original position after the auxiliary plate 6 moves. As the auxiliary plate 6 moves, the sliding ball 514 on its top can slide smoothly to the top of the shell body 3. When the sliding ball 514 contacts the top of the auxiliary plate 6, the connecting copper sheet 515 will be clamped between the first fixed copper sheet 516 and the second fixed copper sheet 517. In this state, the connecting copper sheet 515 will not come into direct contact with the first fixed copper sheet 516 and the second fixed copper sheet 517, thereby ensuring the normal operation of the circuit.

[0046] Working principle of engine parts casing defect detection device:

[0047] Step 1: Place the shell body 3 to be tested into the material frame 2 in sequence, and start the driving motor 22 to drive the connecting block 23 to rotate synchronously, and the connecting block 23 drives the rotating rod 24 to rotate, so that the rotating rod 24 drives the lifting seat 27 and the pushing rod 211 to rotate, so that the pushing rod 211 pushes the shell body 3 in the material frame 2 to move toward the side of the detection component 5;

[0048] Step 2: When the shell body 3 pushes the auxiliary plate 6 to move to one side on the cross bar 61, the fifth damping spring 62 is compressed, so that the shell body 3 moves to the side of the sliding ball 514. When the sliding ball 514 moves to the recessed part of the shell body 3, the limit block 520 is pushed downward under the elastic force of the second damping spring 521. The limit block 520 drives the moving rod 513 and the sliding ball 514 to move downward. The moving rod 513 mobilizes the connecting copper sheet 515 to move downward, so that the connecting copper sheet 515 contacts the two first fixed copper sheets 516, so that the connecting copper sheet 515, the two first fixed copper sheets 516, the first wire, the first power supply and the first alarm light 518 are connected in series, so that the first power supply Provide electric energy so that the first alarm light 518 performs an alarm process; when the sliding ball 514 moves to the convex part of the shell body 3, it can push the sliding ball 514, the moving rod 513, the limit block 520, and the connecting copper sheet 515 to move upward, and compress the second damping spring 521, so that the connecting copper sheet 515 contacts the two second fixed copper sheets 517, so that the connecting copper sheet 515, the two second fixed copper sheets 517, the two wires, the two power supplies and the second alarm light 519 are connected in series, so that the two power supplies provide electric energy, so that the second alarm light 519 performs an alarm process; through the alarm process of the first alarm light 518 or the second alarm light 519, the surface defects of the shell body 3 can be detected and processed;

[0049] Step three, when a concave or convex part appears on the outer shell body 3, it drives the moving rod 513, the sliding ball 514, the limit block 520, and the V-block 523 to move downward or upward, and the V-block 523 pushes the guide column 530 and the sealing plate 526 to move toward the side of the hopper 524. At the same time, under the elastic force of the third damping spring 532, the guide column 530 always slides in contact with the outer wall of the V-block 523, so that the position of the discharge hole 527, the discharge hopper 525, and the pump body 528 correspond to each other, and the marking material in the hopper 524 and the discharge hopper 525 flows to the pump body 528 through the discharge hole 527, and is extracted by the pump body 528, so that the marking material is sprayed through the discharge pipe 529 to the surface defects of the outer shell body 3. This helps to quickly identify and handle unqualified products during the production process, thereby improving production efficiency and product quality.
