Description

As a critical component, the quality of the turbocharger housing directly affects the reliability and stability of the entire turbocharging system. In the production process of the turbocharger housing, the casting blank is the initial and crucial step. The turbocharger housing casting blank is a key component in the turbocharging system, representing the initial form of the turbocharger housing after casting production but before final machining and surface treatment. Due to its complex manufacturing process, various defects are prone to occur during casting, such as porosity, sand holes, shrinkage cavities, cracks, and dimensional deviations. If these defects are not detected promptly and accurately, subsequent processing will not only waste significant resources, but defective products assembled into the system may also lead to serious safety hazards and performance failures.

[0034] 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.

[0035] Example 1;

[0036] Please see Figure 1-10The present invention provides a technical solution: a turbocharger housing casting blank inspection device, including a frame 1 and a remote control terminal. The frame 1 is used to support the wiring layout of the electrical components required for inspection. The remote control terminal is integrated outside the device and has a data processing system and a control system installed inside. The data processing system is used to collect and analyze the inspection parameters, and the control system is used to automatically control the electrical components in the device according to the inspection situation.

[0037] A testing platform 2 is fixedly connected to the top of the frame 1. A feeding device 3 is installed on the top of the testing platform 2. The feeding device 3 is a conveyor belt that is driven by a motor through a belt to drive a roller. The power is transmitted by the friction between the belt and the pulley. The conveyor belt transports at fixed intervals t. The conveyor belt is used to circulate and transport individual airbags. The airbags are placed in an orderly and centered manner on the top of the conveyor belt by means of a robotic arm or other means. The airbag inflation port is made of a rigid material. After placement, the airbag inflation port always faces vertically upward. The airbags transported by the conveyor belt are always at fixed intervals. The end of the feeding device 3 closest to the center of the testing platform 2 is the output end, and the other end is the input end.

[0038] A lateral displacement mechanism 4 is installed above the detection platform 2 near the output end of the feeding device 3. The lateral displacement mechanism 4 includes a support frame for supporting the whole, a guide rail is installed above the support frame, and a slider 5 is slidably connected to the guide rail. A lead screw is set on one side of the guide rail, and the lead screw bearing is connected to the support frame. One end of the lead screw is fixedly connected to a servo motor through a coupling. The slider 5 is threadedly rotatably connected to the lead screw. After the servo motor is powered on, it converts electrical energy into mechanical energy and outputs rotational motion. Since the lead screw and the servo motor are rigidly connected through the coupling, the lead screw rotates synchronously. The slider 5 is threadedly engaged with the lead screw. When the lead screw rotates, the rotational motion of the lead screw is converted into linear motion of the slider 5 along the direction of the guide rail, thereby realizing the lateral displacement of the slider 5.

[0039] like Figure 3 , 4 As shown, an electric push rod 6 is fixedly connected to the surface of the slider 5. A rotating joint 7 is fixedly connected to the telescopic end of the electric push rod 6. A rotary motor 8 is fixedly connected to one side of the rotating end of the rotating joint 7 through a coupling, thereby electrically controlling the rotation of the rotating joint 7. A pneumatic connector 9 is fixedly connected to the rotating end of the rotating joint 7. The pneumatic connector 9 is pneumatically controlled. After being quickly inserted into the interface, it releases gas to expand, so that the structure connected to the interface is used to quickly connect with the airbag. An air inlet pipe is provided on the pneumatic connector 9. The air inlet pipe is fixedly connected to an electric air pump (not shown in the figure) through a pipeline, thereby inflating the airbag. A pressure sensor is installed in the pipeline to provide feedback on the pressure inside the airbag.

[0040] like Figure 1 , Figure 3 , Figure 5 and Figure 6 As shown, a positioning mechanism is installed above the testing platform 2. The positioning mechanism includes a mounting base 10, which is fixedly connected above the testing platform 2. The mounting base 10 is parallel to the feeding device 3, which facilitates receiving the conveying of the lateral displacement mechanism 4. A placement groove is opened in the middle of the mounting base 10 for placing the turbocharger housing casting blank. The blank 22 is placed in the placement groove. Roller 111 and roller 212 are respectively connected to the two sides of the placement groove by bearings. The same side of roller 111 and roller 212 are driven by belt 1 and belt 1 pulley. The other end of roller 212 is fixedly connected to the output shaft of the rotary motor by belt 2 and belt 2 pulley, thereby realizing the synchronous rotation drive of roller 111 and roller 212.

[0041] A vertical plate 12 is fixedly connected to the upper part of the mounting base 10 near the side of the second roller 112. A support rod 13 is fixedly connected to the side of the vertical plate 12 away from the first roller 111 and the second roller 112 via a plate component. Two displacement plates 14 are sleeved on the support rod 13. An upper clamping sleeve 15 is fixedly connected above the opposite side of the two displacement plates 14. A sliding assembly 16 is provided below the support rod 13. The sliding assembly 16 is a belt and pulley driven structure, such as... Figure 6 As shown, two connecting plates 18 are fixedly connected to the belt, and the two connecting plates 18 are located on the upper and lower sides of the belt respectively. The two connecting plates 18 are fixedly connected to the opposite side of the two displacement plates 14 respectively. A cylinder 17 is also fixedly connected to one side of the upright plate 12. The cylinder 17 is located between the support rod 13 and the sliding assembly 16. The telescopic end of the cylinder 17 is fixedly connected to one side of one of the displacement plates 14. When compressed air is introduced into the cylinder 17, the piston is displaced by the gas pressure in the cylinder, which drives the displacement plate 14 connected to it to slide on the support rod 13. Meanwhile, since the displacement plate 14 is fixedly connected to the connecting plate 18 in the sliding assembly 16, the movement of the displacement plate 14 will drive the connecting plate 18 to move, thereby causing the belt to rotate on the pulley. At this time, the connecting plate 18 on the other side will drive another displacement plate 14 to move in the opposite direction to the aforementioned connecting plate 18, thereby realizing the opposite or opposite displacement of the two displacement plates 14, so that the two upper clamping cylinders 15 clamp the blank 22.

[0042] Furthermore, a second cylinder is provided below the sliding assembly 16. The second cylinder is fixedly connected to one side of the upright plate 12 via a plate. A second support rod 19 is fixedly connected below the second cylinder. A second displacement plate 20 is sleeved on the second support rod 19. A lower clamping cylinder 21 is fixedly connected to the opposite side of the second displacement plate 20. The same connecting plate 18 is fixedly connected to the opposite side of the two second displacement plates 20, and the connecting plate 18 is fixedly connected to the same sliding assembly 16 in the same manner, so that the two lower clamping cylinders 21 clamp the blank 22.

[0043] Pressure sensor 1 and pressure sensor 2 are respectively installed inside the walls of the upper clamping cylinder 15 and the lower clamping cylinder 21, respectively, to provide feedback on the clamping status of the blank 22.

[0044] like Figure 2 , Figure 7-10 As shown, a contour detection assembly is installed above the detection platform 2. The contour detection assembly is located between the feeding device 3 and the mounting base 10. The contour detection assembly includes an electric telescopic rod 23, which is bearing-connected to the top of the detection platform 2. The fixed end of the electric telescopic rod 23 is fixedly connected to a rotary motor via a coupling. The rotary motor is installed inside the frame 1 and is used to drive the rotation of the electric telescopic rod 23. A rotating plate 24 is fixedly connected to the telescopic end of the electric telescopic rod 23. The rotating plate 24 is triangular in shape, and all triangles are rounded. The telescopic end of the electric telescopic rod 23 is concentric with the center of one of the corners of the rotating plate 24. Sliding rod 1 25 and sliding rod 26 are respectively provided on both sides of the rotating plate 24. The two ends of sliding rod 1 25 are... Connecting end 1 251 and connecting end 252 are fixedly connected to each other. Connecting end 1 251 is fixedly connected to one of the remaining two corners of the rotating plate 24. Connecting end 3 261 and connecting end 4 262 are fixedly connected to each end of the sliding rod 26. Connecting end 3 261 is fixedly connected to the remaining corner of the rotating plate 24. A contour detection element 27 is provided at the end near connecting end 252 and connecting end 4 262. The contour detection element 27 is arc-shaped, and several distance sensors are installed in the concave surface of the contour detection element 27. The several distance sensors are evenly and densely distributed and used to detect the distance from the object to the inner surface of the contour detection element 27. Connecting end 252 and connecting end 4 262 are fixedly connected to the two ends of the contour detection element 27, respectively. When the rotary motor drives the electric telescopic rod 23, it rotates, causing the rotating plate 24 to rotate around one corner as the center. This causes the sliding rod 25 and the sliding rod 26 to move back and forth in opposite directions, thereby adjusting the flipping of the contour detection component 27 so that it surrounds the hollow turbine shell structure of the blank 22. The distance sensor reads the distance from the turbine shell to the contour detection component 27, thereby providing feedback on the size of the turbine shell of the blank 22.

[0045] like Figure 1 , Figure 3 , Figure 7 As shown, a discharge conveyor belt 28 is installed on the side of the mounting base 10 away from the feeding device 3, which is used to send out the blanks 22 that fail the inspection.

[0046] In this embodiment, the remote control terminal first presets the qualified parameters of the current blank 22. The blank 22 is placed into the placement slot by a robotic arm or other transport mechanism. Cylinder 17 and Cylinder 2 push it out, causing the upper clamping cylinder 15 and lower clamping cylinder 21 to move towards each other until pressure sensors 1 and 2 respectively return values. At this point, the values ​​returned by the pressure sensors are compared with the preset appropriate clamping force value to ensure that the clamping force is sufficient to stably fix the blank 22 without damaging it due to excessive force. Simultaneously, the extension distance of cylinders 17 and 2 provides feedback on the size of the blank 22. Specifically, the extension distance of the cylinders can be accurately measured by displacement sensors. The displacement sensors convert the displacement signal into an electrical signal and transmit it to the data processing system. Combined with the initial position of the clamping cylinders and relevant geometric parameters, the data processing system calculates the size data of the blank 22 at the corresponding position. After detecting the current area size, the upper clamp 15 and lower clamp 21 are released, and the rotary motor starts, driving the first roller 111 and the second roller 112 to rotate, causing the blank 22 to flip as a whole. The upper clamp 15 and lower clamp 21 keep the blank 22 stable. The cylinders 17 and 2 are driven to extend and perform size detection on different areas of the blank 22 and provide feedback. At the same time, the contour detection component 27 continuously circles the surface of the turbine housing during the flipping process, and the distance sensor provides the distance value. The distance value is then compared with the preset qualified value to achieve a comprehensive detection of the turbine housing size.

[0047] After the dimensional inspection is completed, cylinders 17 and 2 drive the upper clamping cylinder 15 and the lower clamping cylinder 21 to move towards each other to clamp the blank 22. At the same time, the feeding device 3 feeds the airbag. When the airbag moves to the fixed position below the pneumatic connector 9, the rotary motor 8 drives the pneumatic connector 9 to flip and face downward, so that the pneumatic connector 9 is inserted into the airbag inflation port, realizing a quick connection with the airbag. After the connection is completed, the airbag is transferred to the blank 22 by the lateral displacement mechanism 4. The airbag is pushed out by the electric push rod 6, and the direction of the airbag is adjusted by the rotary motor 8 according to the direction of the air intake channel of the blank 22, so that it is inserted into the air intake channel of the blank 22. At this time, the electric air pump starts to inflate the inside of the airbag. During the inflation process, the working parameters of the electric air pump (such as inflation pressure, inflation time, etc.) are controlled by the remote control terminal to ensure that the airbag can safely and accurately fill the inside of the channel of the blank 22. The inflated airbag will fill the channel inside the blank 22. The volume of the air intake channel of the blank 22 can be fed back based on the current inflation volume of the airbag. The volume of gas in the airbag can be measured in real time by installing a gas flow meter on the outlet pipe of the electric air pump, thereby obtaining the volume of the air intake channel of the blank 22 and checking the qualification of the air intake channel. Finally, the qualified blank 22 will be sent to the subsequent processing, while the blank 22 with unqualified size or channel will be transferred to the unloading conveyor belt 28 by the robot for recycling.

[0048] Through the above embodiments, automated detection is achieved using a remote control terminal data processing and control system. The feeding device 3 delivers airbags at fixed intervals t to ensure orderly feeding. The lateral displacement mechanism 4 cooperates with the pneumatic connector 9 to achieve precise docking and position adjustment of the airbags. The positioning mechanism uses a clamp and pressure sensor to stably hold the blank, and combines roller rotation to achieve multi-area size detection. The contour detection component uses a distance sensor to surround the turbine housing structure to achieve precise size measurement. Finally, defective products are automatically discharged through the unloading conveyor belt 28. The entire system realizes automated, high-precision, and multi-dimensional detection of turbocharger housing casting blanks, effectively improving detection efficiency and accuracy, and reducing manual intervention costs.

[0049] Example 2;

[0050] Based on Embodiment 1, in this embodiment, in order to improve the overall quality of the turbocharger housing casting blank, the positioning mechanism and the contour detection mechanism are used to detect it synchronously. Specifically, when the airbag fills the air intake channel of the blank 22, the rotating motor is driven to make the first roller 111 and the second roller 112 rotate slightly. At the same time, the rotating motor 8 drives the pneumatic connector 9 to rotate synchronously, so that the airbag is always inside the blank 22. At this time, the upper clamping cylinder 15 and the lower clamping cylinder 21 are driven to move, and pressure within the bearing range is applied to the surface of the blank 22. When the blank 22 is normally filled, the internal gas pressure value of the airbag is set to P, and the internal gas pressure of the airbag detected by the pressure sensor is P1.

[0051] When P1=P, it indicates that the blank 22 can still maintain the same shape as before the pressure after being compressed, and the blank 22 is of qualified quality.

[0052] When P1 < P, it indicates that the blank 22 is deformed due to internal compression after being pressed, causing some of the gas in the air bladder to be squeezed out. The blank 22 is of poor quality and is marked as unqualified.

[0053] Furthermore, when P1 < P, P1 drops abruptly, indicating that the airbag has ruptured. At this point, the remote control terminal immediately sends a command to stop the electric air pump from inflating and controls the electric push rod 6 to retract the pneumatic connector 9 to prevent damage to the detection device caused by the airbag bursting. Simultaneously, the blank 22 is marked as a seriously defective product and sent out via the unloading conveyor belt 28, and the detection data is recorded in the system for subsequent traceability and optimization of the production process.

[0054] When P1 > P, the turbine housing part of the blank 22 is quickly inspected by the contour detection mechanism, and the inside of the turbine housing is inspected again by the distance sensor. The condition of the inside of the turbine housing is judged by the distance difference H between adjacent distance sensors. If H = 0 at this time, it means that the turbine housing of the blank 22 is intact and there is no crack problem. The excessive pressure is caused by the deformation of the air bag. If H ≠ 0 at this time, it means that the turbine housing of the blank 22 has cracked. The blank 22 is directly sent to the unloading conveyor belt 28 and is regarded as a defective product.

[0055] Through the above embodiments, various defects such as internal deformation, structural cracking, and air bladder rupture in the blank 22 can be accurately identified; intelligent classification of defect types can be achieved, improving detection accuracy; and data correlation analysis can provide quantitative basis for casting process optimization, effectively shortening the process adjustment cycle.
