Description

Technical Field

[0001] This invention relates to the field of vortex shell testing equipment, specifically an automatic vortex shell testing device. Background Technology

[0002] The volute chamber is one of the core components of a turbocharger and is commonly used in the automotive industry. It is designed to withstand extreme high temperatures, thermal shock and alternating stress, as well as internal pressure and vibration. In actual production, volute chamber testing equipment is usually required to test various data of the volute chamber.

[0003] Publication No. CN119044309A discloses an automatic detection device for vortex holes in a vortex shell. The device is characterized by: a transport component slidably connected to a worktable; the top of the worktable being fixedly connected to a housing; the transport component being located inside the housing; a detection component being installed inside the worktable; the housing including a housing body with a guide groove on one inner side; the transport component including a slide with a placement groove for the vortex shell in the middle; both sides of the slide being rotatably connected to a rotating frame; the rotating frame being movably connected to a pressing component; a limit component being installed inside the slide on the side away from the guide groove; and the pressing component including an L-shaped rod movably connected to the middle of the rotating frame at the end away from the slide; a circular hole for the L-shaped rod to pass through on the rotating frame; a fixed connection between the end of the L-shaped rod near the slide and the middle of a cross plate; a fixed connection between the cross plate and the inner side of a pressure ring; an annular rubber layer at the bottom of the pressure ring; and a guide wheel rotatably connected to the side of the L-shaped rod away from the cross plate. This device ensures that the pressure ring can always press down on the vortex shell. In actual testing, the turbine housing needs to be placed under normal temperature and pressure conditions to measure various data inside the turbine housing. However, when the automobile turbine housing is in operation, the exhaust gas usually carries a certain temperature. When the high-temperature exhaust gas enters the turbine housing, it raises the internal temperature of the turbine housing. Furthermore, the turbine housing is subjected to continuous impact from the high-temperature exhaust gas, causing it to vibrate. Existing technology uses a vibration platform to vibrate the bottom of the turbine housing under normal temperature and pressure conditions to measure various data. This method is obviously quite different from the actual working environment of the automobile turbine housing, resulting in low accuracy and reliability of the turbine housing data when applied to actual use. There is room for further improvement in the testing effect of existing equipment on turbine housing performance. Summary of the Invention

[0018] 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.

[0019] Example Please see Figures 1 to 4 An automatic vortex shell detection device includes a main body 1. A control center 14 is fixedly connected to one end surface of the main body 1. A data chamber 12 is fixedly connected to one side of the top of the main body 1. A detection body 13 is fixedly connected to the other side of the top of the main body 1. A vision camera and a collection port are provided inside the detection body 13. The collection port extends into the interior of the main body 1. An opening and closing door 11 is rotatably connected to the other end surface of the main body 1. A negative pressure component 2 is fixedly connected to one end of the bottom inner wall of the main body 1. A fixing component 3 is fixedly connected to the other end of the bottom inner wall of the main body 1. In actual testing, the turbine housing needs to be placed under normal temperature and pressure conditions to measure various data inside the turbine housing. However, when the automobile turbine housing is in operation, the exhaust gas usually carries a certain temperature. When the high-temperature exhaust gas enters the turbine housing, it raises the internal temperature of the turbine housing. Furthermore, the turbine housing is subjected to continuous impact from the high-temperature exhaust gas, causing it to vibrate. In the existing technology, a vibration platform is used to vibrate the bottom of the turbine housing under normal temperature and pressure conditions to measure various data of the turbine housing. This method is obviously very different from the actual working environment of the automobile turbine housing, resulting in low accuracy and reliability of the turbine housing data when applied to actual use. This invention discloses an automatic turbine housing detection device. In its initial state, the main body 1 of the device is at normal temperature and pressure. The opening and closing door 11 is manually opened, and the bottom of the turbine housing is placed on top of the fixing component 3. Then, the control center 14 controls the opening of the negative pressure component 2 and the fixing component 3. The fixing component 3 opens to fix and seal the turbine housing itself, while the negative pressure component 2 opens to deliver high-temperature gas from inside the turbine housing, heating the interior of the turbine housing. This simulates the temperature rise of the turbine housing when the engine delivers high-temperature exhaust gas to the turbine housing of a turbocharger during engine startup. The device only... The internal temperature of the turbine housing is increased, creating a temperature difference between the outer and inner walls of the turbine housing. This simulates the temperature difference when the inner wall of the turbine housing heats up while the outer wall is exposed to the engine compartment of a car during turbocharger operation. During this process, a vision camera inside the detection unit 13 records the deformation changes and other data of the turbine housing. The device can simulate the actual working environment of the turbine housing to perform performance testing. Compared with the existing technology's ambient temperature and pressure testing environment, the test results of this technical solution are more consistent with the actual use of the turbine housing, improving the device's testing effect on the turbine housing and making it easier for users to use. Please see Figures 4 to 6Further as described above, the fixing component 3 includes a top post 30, which is fixedly connected to the top of the fixing component 3. A sealing ring 31 is fixedly connected to the outer surface of the top post 30. The shape and size of the sealing ring 31 are adapted to the shape and size of the inner wall of the bottom side of the volute. Linear drive components 32 are fixedly connected to the front and rear surfaces of the fixing component 3. The linear drive components 32 are configured as electric push rods. Movable blocks 320 are fixedly connected to the output ends of the two linear drive components 32 near their symmetrical planes. The movable blocks 320 are slidably connected inside the linear drive components 32 and extend to the linear drive components 32 near their symmetrical planes. An adjusting plate 321 is fixedly connected to the extension of the movable block 320 on one side of the surface. A reversible axial flow fan is fixedly connected inside the negative pressure component 2. An air distribution port 22 is fixedly connected to the top of the negative pressure component 2. A first conveying pipe 23 is fixedly connected to the output end of the other end of the negative pressure component 2. A heating component 24 is fixedly connected to the other end of the first conveying pipe 23 and is fixedly connected to the bottom inner wall of the main body 1. An electromagnetic heater is fixedly connected inside the heating component 24. A second conveying pipe 25 is fixedly connected to the other end of the heating component 24. The shape and size of the second conveying pipe 25 are adapted to the shape and size of the collecting pipe of the vortex. When the opening and closing door 11 is opened in the above steps, the vortex shell is placed on top of the fixing component 3. At this time, the top column 30, along with the sealing ring 31, enters the interior of the vortex shell, and the sealing ring 31 is tightly attached to the inner wall of the vortex shell, so that the interior of the vortex shell is in the sealing ring 31 environment. The second conveying pipe 25 is sleeved on the collection pipe of the vortex shell itself. Then, the two linear drive components 32 are activated by the control center 14. The linear drive components 32 are activated and drive the adjusting plate 321 to move through the movable block 320. The adjusting plate 321 moves and is fixed to the vortex shell. Then, the negative pressure component 2 is activated by the control center 14. The reversible axial flow fan inside the negative pressure component 2 draws gas from the outside through the air distribution port 22 and delivers the gas through the first conveying pipe 23. The gas is fed into the heating component 24, where the electromagnetic heater heats the gas. The gas is then transported to the inside of the volute through the second delivery pipe 25 and the volute's own collection pipe. The volute is affected by the heat transfer from the high-temperature gas, causing the temperature of the inner wall of the volute to rise. At this time, because the inside of the volute is a sealed ring 31, the internal air pressure of the volute increases. As the internal air pressure of the volute continues to increase, the gas inside the volute rushes towards the turbine blades, causing them to rotate. At this time, the volute is in the same working state as the turbocharger without being connected to other components. During the testing process, the device does not need to repeatedly connect external equipment to the volute, which improves the testing efficiency of the device and further simulates the actual working environment of the turbine, improving the testing effect of the device and making it easier for users to use. Please see Figures 4 to 6Furthermore, as described above, a vacuum bag 322 is fixedly connected to the bottom of the adjusting plate 321. The vacuum bag 322 contains multiple rigid particles, specifically ceramic microspheres. The vacuum bag 322 provided at the bottom of the adjusting plate 321 is used to make contact with the outer wall of the volute shell one step before the adjusting plate 321 when the movable block 320 moves. Please see Figures 3 to 6 Furthermore, in the above description, an extraction tube 21 is fixedly connected to one end surface of the vacuum bag 322, and a conveying chamber 20 is fixedly connected to the other end of the two extraction tubes 21. The conveying chamber 20 is fixedly connected to the top of the negative pressure component 2 and is connected to the input end of the reversible axial flow fan inside the negative pressure component 2. Since the outer wall of the vortex shell is usually an irregular geometric pattern, conventional clamping equipment typically has a small contact area with the outer wall, making it difficult to fix the vortex shell without applying excessive force. However, applying excessive force can easily cause deformation of the outer wall of the vortex shell. In the above steps, the movement of the movable block 320 drives the adjustment plate 321 to move, and the movement of the adjustment plate 321 drives the vacuum bag 322 to move until the vacuum bag 322 contacts the outer wall of the vortex shell. At this time, the negative pressure fan is turned on by the control center 14. The negative pressure fan draws air from the outside through the air outlet 22 and simultaneously draws air into the vacuum bag 322 through the two extraction pipes 21. As the air inside the vacuum bag 322 decreases and the air pressure drops, the outer wall of the vacuum bag 322 gradually fits into the outer wall of the vortex shell, allowing the vacuum bag 322 to adapt to the vortex shell. The irregular geometric pattern on the outer wall of the shell maintains the maximum contact area. The rigid particles inside the vacuum bag 322 can squeeze and lock each other when the vacuum bag 322 is fully attached to the outer wall of the vortex shell, thus forming a hard rigid body that is interlocked with the surface shape of the workpiece. This creates rigid contact with the outer wall of the vortex shell and works with the fixing component 3 and the adjusting block to fix the vortex shell. The air inside the vacuum bag 322 is extracted by the negative pressure component 2 and transported to the heating component 24 to heat the inner wall of the vortex shell. Subsequent reset only requires controlling the reversible axial flow fan to supply air into the extraction pipe 21. Thus, the device can be adapted to fix the outer wall of the vortex shell with irregular shape, while avoiding large forces on the outer wall of the vortex shell that could cause deformation. This improves the detection effect of the device and makes it easier for users to use. Please see Figures 3 to 6 Furthermore, as described above, mounting grooves are provided on both sides of the top column 30, and a vibration component 33 is fixedly connected inside the mounting groove. The vibration component 33 is electrically connected to the control center 14. The vibration component 33 is used to simulate the vibration generated by the engine conveying high-temperature exhaust gas through the collection pipe to the inside of the volute during the operation of the volute, the collision between the inside of the volute and the high-temperature gas, and the vibration caused by the exhaust pulse. Compared with the existing equipment that vibrates the volute from the bottom, this technical solution generates vibration from the inner wall of the volute when a temperature difference is formed between the inner wall and the outer wall of the volute. This makes the detection environment of the volute more consistent with the actual working environment, improves the detection effect of the device, and makes it easier for users to use. Please see Figures 7 to 8 Further, in the above description, the vibration assembly 33 includes a rotary drive assembly 330, which is fixedly connected to the inner wall of the bottom side of the vibration assembly 33. Specifically, the rotary drive assembly 330 is a heat-resistant drive motor. An output shaft 331 is fixedly connected to the top output end of the rotary drive assembly 330. An adjusting arm 332 is fixedly connected to the end of the output shaft 331 away from the rotary drive assembly 330. A rotating rod 333 is fixedly connected to the end of the adjusting arm 332 away from the output shaft 331. A movable disk 334 is provided at the top of the rotating rod 333, and the bottom of the movable disk 334... The part has an open movable groove, and the end of the movable groove near the center of the fixed component 3 is arc-shaped, and the end of the movable groove away from the center of the fixed component 3 is also arc-shaped. The rotating rod 333 is slidably connected inside the movable groove. The end of the movable disk 334 away from the center of the fixed component 3 is fixedly connected to two through rods 335. The two through rods 335 pass through the vibration component 33 and extend to the outside of the vibration component 33. The extension of the two through rods 335 is fixedly connected to a striking plate 336. The shape and size of the striking plate 336 are adapted to the shape and size of the inner wall of the bottom side of the vortex shell. In the above steps, when the high-temperature gas is delivered to the inner wall of the vortex shell, the rotary drive assembly 330 is activated by the control center 14. The activation of the rotary drive assembly 330 drives the adjusting arm 332 to rotate via the output shaft 331. The rotation of the adjusting arm 332 drives the rotating rod 333 to rotate. The rotation of the rotating rod 333 drives the movable disk 334 to perform linear reciprocating motion via the movable slot. The movement of the movable disk 334 drives the striking plate 336 to perform linear reciprocating motion on the inner wall of the vortex shell via two through rods 335. The movement of the striking plate 336 taps the inside of the vortex shell and generates vibration. This motion mode is high-frequency. The small-amplitude reciprocating motion allows the vibration to generate continuous pressure waves in the gas inside the turbine housing. The vibration generated in this way is continuous and its vibration mode is more similar to the vibration generated by the exhaust pulse. At the same time, since the vacuum bag 322 rigidly fixes the outer wall of the turbine housing in a completely fitted manner, it avoids the movement of the turbine housing caused by vibration and makes the installation of the turbine housing similar to its actual operation (bolted to the inside of the engine compartment through the external protective frame). This further improves the simulation effect of the device on the actual working environment of the turbine housing, improves the detection effect of the device, and makes it easier for users to use. Please see Figures 1 to 2Furthermore, as described above, a visible panel 10 is fixedly connected to the front surface of the main body 1 of the device, and the visible panel 10 is made of transparent material. The visual panel 10 is used by the user to observe the volute detection status inside the main body 1 of the equipment during the volute detection experiment and when the door 11 is closed. Please see Figure 2 Furthermore, as described above, the control center 14 comprises a display system, a data server, a console, an auxiliary support system, and an execution unit, and the display system, data server, console, auxiliary support system, and execution unit are electrically connected to each other. The control center 14 is used to control the start-up, shutdown and use of various components inside the main body of the equipment 1, so as to ensure the normal operation of the device.
