Description

Technical Field

[0001] The invention belongs to the technical field of turbocharger detection, in particular to an automobile turbocharger detection device. Background Art

[0002] A turbocharger is actually an air compressor that increases the intake volume by compressing air. It uses the inertial force of the exhaust gas discharged by the engine to drive the turbine in the turbine chamber, and the turbine drives the coaxial impeller, which presses the air sent from the air filter pipe to enter the cylinder with pressure. In order to ensure the stability of the turbocharger's working performance, the turbocharger needs to be tested for its boost power after production to ensure that it can perform normal and stable boosting work.

[0003] Since turbochargers are usually mass-produced and have a strong boosting effect when working, they not only require effective safety measures but also relatively high detection efficiency. In addition, turbochargers themselves will generate strong mechanical vibrations when working, and the connection between the exhaust port and the detection component is prone to loosening, resulting in adverse phenomena such as air leakage and pressure release, so improvements are needed. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention solves the technical problems thereof by adopting a technical solution: an automobile turbocharger detection device, comprising a receiving base, wherein the upper surface of the receiving base is evenly provided with buckling devices;

[0005] The storage base comprises a plane box, and external support frames are symmetrically fixed to the front and rear sides of the outer surface of the plane box, and the upper surface of the plane box is evenly provided with receiving grooves, and the middle part of the inner cavity of the receiving groove is evenly provided with blocking baffles, and the middle part of the inner cavity of the plane box is evenly provided with blocking devices, and the inner cavity of the plane box is evenly provided with pressure zones, and the inner cavity of the plane box is evenly provided with pressure measuring devices through the pressure zones;

[0006] The buckling device comprises a control base plate, a traction rod is symmetrically arranged on the top of the inner cavity of the control base plate, an upper closed shell is fixedly connected to the top of the outer surface of the traction rod, and the upper closed shell is divided into a turbocharger accommodating area at the front, a connecting area in the middle and an air accommodating area at the rear. Figure 4 As shown, the bottom of the upper closed shell can be perfectly matched with the accommodating groove, a spring rotating plate is arranged in the middle of the inner cavity of the upper closed shell, an air intake duct is fixedly connected to one side of the top of the inner cavity of the upper closed shell, and the turbocharger draws air from the outside for pressurization through the air intake duct, a guide bolt sleeve is fixedly connected to the other side of the top of the inner cavity of the upper closed shell, a protective device is arranged on the inner wall of the guide bolt sleeve, and a buffer inner pressure plate is symmetrically arranged on the front part of the inner wall of the upper closed shell.

[0007] Furthermore, the pressure measuring equipment includes a force-bearing sliding disc, which is adapted to the caliber of the pressure zone and can completely block the pressure zone. A resistance sleeve is fixedly connected to the lower surface of the force-bearing sliding disc, and the inner cavity area of ​​the resistance sleeve can be inflated and pressurized so that the resistance sleeve has a certain initial resistance to offset the gravity of the force-bearing sliding disc and prevent the force-bearing sliding disc from sliding downward too quickly when it is under pressure. A pressure-sensitive bottom cylinder is fixedly connected to the bottom of the inner cavity of the resistance sleeve, and a signal wire is slidably connected to the axis of the inner cavity of the force-bearing sliding disc through a through-hole, and the bottom end of the signal wire is directly connected to the inner cavity of the pressure-sensitive bottom cylinder, so as to transmit the electrical signal of the pressure-sensitive bottom cylinder to obtain test data.

[0008] Furthermore, the outer surface of the traction rod is slidably connected to the inner cavity of the plane box, and the top end of the traction rod extends to the outside of the plane box, the top end of the spring rotating plate is rotatably connected to the upper closed inner wall, and the bottom end of the spring rotating plate is pressed against the outer surface of the blocking partition. The bottom of the outer surface of the upper closed shell is plugged into the inner wall of the receiving groove, the outer surface of the pressure-sensitive bottom cylinder is fixedly connected to the inner cavity of the plane box through the pressure zone, the outer surface of the force-bearing sliding disk is slidably connected to the inner cavity of the plane box through the pressure zone, and the top end of the signal wire extends to the outside of the upper closed shell.

[0009] Furthermore, the blocking device includes a control bottom box, the upper part of the inner cavity of the control bottom box is evenly provided with an adapting filling plate, the upper part of the outer surface of the adapting filling plate is fixedly connected with a blocking sealing plate, the front part of the inner cavity of the plane box is provided with an exhaust groove, and both ends of the exhaust groove extend to the outside of the plane box. The outer surface of the control bottom box is fixedly connected to the middle part of the inner cavity of the plane box, the top of the adapting filling plate extends to the outside of the plane box through the adapting groove, and the upper surface of the blocking sealing plate and the top of the inner wall of the plane box are pressed against each other, the inner cavity of the control bottom box is fixedly connected to the inner cavity of the pressure-sensitive bottom tube through the control wire, and the exhaust groove is connected to the storage area where the control bottom box is located. When the adapting filling plate is pulled down by the control bottom box, the high-pressure gas will enter the storage area where the control bottom box is located, and then be discharged through the exhaust groove, thereby realizing the pressure relief work.

[0010] Furthermore, the protection device includes a long threaded rod, the bottom end of which is fixedly connected to a metal sealing disk, the outer surface of which is perfectly matched with the caliber of the pressure zone, and when the metal sealing disk is inserted into the pressure zone, the top area of ​​the force-bearing sliding disk is sealed. At this time, the turbocharger continues to pressurize, and the pressure will not act on the upper surface of the force-bearing sliding disk, thereby keeping the data measured by the pressure-sensitive bottom cylinder unchanged. The upper part of the outer surface of the protection device is rotatably connected to a twisting device, the outer surface of the long threaded rod is threadedly connected to the inner wall of the guide bolt sleeve, the bottom end of the long threaded rod extends to the interior of the upper closure shell, the top end of the signal wire extends to the outside of the long threaded rod, and the outer surface of the signal wire is fixedly connected to the inner wall of the long threaded rod.

[0011] Furthermore, the torsion device comprises a threaded rod sleeve, the front and rear sides of the inner cavity of the threaded rod sleeve are symmetrically provided with engaging wheels, the axis of the inner cavity of the engaging wheel is symmetrically provided with a torque motor through a control rod, the top of the inner cavity of the threaded rod sleeve is evenly provided with receiving ends, the front and rear sides of the threaded rod sleeve are symmetrically provided with adjustment rods, and the bottom end of the adjustment rod is fixedly connected with a control tensioner. The bottom end of the control tensioner is fixedly connected to the outer surface of the upper closed shell, the outer surface of the engaging wheel is rotatably connected to the upper part of the outer surface of the long threaded rod, and the middle part of the inner wall of the threaded rod sleeve is sleeved with the outer surface of the long threaded rod.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. Since the turbocharger is located in the internal area of ​​the upper closed shell during operation, and the upper closed shell is buckled with the receiving groove, the sealing of the detection environment of the turbocharger is guaranteed and will not be disturbed by the outside. When the turbocharger is pressurized, its outer surface will be restricted by the buckled upper closed shell, and the internal buffer inner pressure plate will be used for shock absorption and buffering. The pressurized gas of the turbocharger will definitely pass into the pressure area, so the connection between the exhaust port and the detection component will not be easily loosened and then leaked and depressurized, and the safety of pressurized gas transmission can be fully guaranteed.

[0014] 2. The device can divide the turbochargers into several groups for unified testing, determine the turbocharger's pressurization power and pressurization rate based on the data obtained, and determine whether the turbocharger is faulty by comparison. Since there is a unidirectionally rotating spring rotating plate in the middle area of ​​the upper closed shell, the pressurization work of the pressurized area will not be affected during the testing work. After the pressurization work is completed, the spring rotating plate will separate the internal area of ​​the upper closed shell, thereby preventing the air pressure inside the pressurized area from flowing back to the outside through the turbocharger, causing air leakage inside the device.

[0015] 3. When the turbocharger is performing pressurization work inside the device, the internal pressure is constantly monitored through the pressure-sensing bottom cylinder. When the pressure is high, the air supply of the air intake pipe can be stopped in time to prevent the internal pressure from continuing to increase. The notch blocked by the adapter filling plate can be opened through the control bottom box in the middle, so that the internal high-pressure gas can be discharged in time through the exhaust groove, and the pressure reduction work can be quickly achieved, so that the operator will not be injured due to the impact of the internal high-pressure gas when opening the upper closed shell.

[0016] 4. After the turbocharger is pressurized to the critical value, the top area of ​​the stressed sliding plate can be sealed by a metal sealing plate to lock the pressure of the stressed sliding plate. If there is no leakage inside the pressure area, the pressure value of the pressure-sensitive bottom cylinder will not change. In this way, the leakage problem inside the pressure area is eliminated, ensuring that the data obtained by the turbocharger will not be distorted, preventing the problem of abnormal turbocharger test results caused by device system problems, and improving the reliability of the device.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.

[0027] Example 1, please refer to Figure 1-Figure 5 , the present invention provides a technical solution: an automobile turbocharger detection device, comprising a receiving base 1, the upper surface of which is evenly provided with buckling devices 2;

[0028] The storage base 1 comprises a plane box 11, and external support frames 12 are symmetrically fixed to the front and rear sides of the outer surface of the plane box 11, and the upper surface of the plane box 11 is evenly provided with a receiving groove 13, and the middle of the inner cavity of the receiving groove 13 is evenly provided with a blocking partition 14, and the middle of the inner cavity of the plane box 11 is evenly provided with a blocking device 15, and the inner cavity of the plane box 11 is evenly provided with a pressure zone 16, and the inner cavity of the plane box 11 is evenly provided with a pressure measuring device 3 through the pressure zone 16;

[0029] The buckling device 2 includes a control base plate 21, a traction rod 22 is symmetrically arranged on the top of the inner cavity of the control base plate 21, and an upper closed shell 23 is fixedly connected to the top of the outer surface of the traction rod 22. The upper closed shell 23 is divided into a turbocharger accommodating area at the front, a connecting area in the middle, and an air accommodating area at the rear. Figure 4 As shown, the bottom of the upper closed shell 23 can be perfectly matched with the accommodating groove 13, a spring rotating plate 24 is arranged in the middle of the inner cavity of the upper closed shell 23, an intake duct 26 is fixedly connected to one side of the top of the inner cavity of the upper closed shell 23, and the turbocharger draws air from the outside for pressurization through the intake duct 26, a guide bolt sleeve 25 is fixedly connected to the other side of the top of the inner cavity of the upper closed shell 23, a protective device 4 is arranged on the inner wall of the guide bolt sleeve 25, and a buffer inner pressure plate 27 is symmetrically arranged on the front part of the inner wall of the upper closed shell 23.

[0030] The pressure measuring device 3 includes a force-bearing sliding disc 33, which is adapted to the caliber of the pressure-bearing zone 16 and can completely block the pressure-bearing zone 16. A resistance sleeve 32 is fixedly connected to the lower surface of the force-bearing sliding disc 33, and the inner cavity area of ​​the resistance sleeve 32 can be inflated and pressurized so that the resistance sleeve 32 has a certain initial resistance to offset the gravity of the force-bearing sliding disc 33 and prevent the force-bearing sliding disc 33 from sliding downward too quickly when it is compressed. A pressure-sensing bottom cylinder 31 is fixedly connected to the bottom of the inner cavity of the resistance sleeve 32, and a signal wire 34 is slidably connected to the axis of the inner cavity of the force-bearing sliding disc 33 through a through-hole. The bottom end of the signal wire 34 is directly connected to the inner cavity of the pressure-sensing bottom cylinder 31, and is used to transmit the electrical signal of the pressure-sensing bottom cylinder 31 to obtain test data.

[0031] The outer surface of the traction rod 22 is slidably connected to the inner cavity of the plane box 11, and the top of the traction rod 22 extends to the outside of the plane box 11, the top of the spring rotating plate 24 is rotatably connected to the upper closed inner wall, and the bottom of the spring rotating plate 24 is pressed against the outer surface of the blocking partition 14. The bottom of the outer surface of the upper closed shell 23 is plugged into the inner wall of the receiving groove 13, the outer surface of the pressure-sensitive bottom cylinder 31 is fixedly connected to the inner cavity of the plane box 11 through the pressure area 16, the outer surface of the force sliding plate 33 is slidably connected to the inner cavity of the plane box 11 through the pressure area 16, and the top of the signal wire 34 extends to the outside of the upper closed shell 23.

[0032] The device is used to conduct centralized inspection of newly produced turbochargers. The turbocharger array is placed in the front area of ​​the receiving slot 13 of the plane box 11, and then the upper closed shell 23 is pressed down by the traction rod 22 until the upper closed shell 23 and the receiving slot 13 are completely closed and docked. At this time, the buffer inner pressure plate 27 and the upper surface of the turbocharger are squeezed against each other to press the turbocharger tightly and fix it. The turbocharger takes in air from the outside by docking with the intake duct 26, and then it is ready to work.

[0033] After the turbocharger is started, it begins to pressurize the internal area of ​​the upper closed shell 23. The air pressure pushes the spring rotating plate 24, opens the middle opening area of ​​the upper closed shell 23, and then enters the rear pressure zone 16. As the turbocharger continues to pressurize, the force sliding plate 33 located inside the pressure zone 16 gradually squeezes the resistance sleeve 32 below and slides down under the action of the air pressure, exerting pressure on the pressure-sensing bottom cylinder 31, and then the pressure-sensing bottom cylinder 31 transmits the pressure signal to the outside world through the signal wire 34, thereby obtaining the pressurization data of the turbocharger in this area. Since each turbocharger performs pressurization work with the same power, the data of the pressure-sensing bottom cylinder 31 can be compared to determine its pressurization power and pressurization speed.

[0034] After the inspection work is completed, the turbocharger stops pressurizing, and then the control bottom box 151 located in the middle pulls the adapter filling plate 152 downward to open the slot in the middle of the plane box 11. At this time, the high-pressure gas enters the area where the control bottom box 151 is located, and is discharged to the outside through the exhaust grooves 17 on both sides to achieve the effect of early decompression, and then the upper sealing shell 23 is opened to take out the turbocharger inside.

[0035] Example 2, please refer to Figure 1-Figure 8 The present invention provides a technical solution: on the basis of Example 1, the blocking device 15 includes a control bottom box 151, and the upper part of the inner cavity of the control bottom box 151 is evenly provided with an adapting filling plate 152, and the upper part of the outer surface of the adapting filling plate 152 is fixedly connected with a blocking sealing plate 153, and an exhaust groove 17 is opened at the front part of the inner cavity of the plane box 11, and both ends of the exhaust groove 17 extend to the outside of the plane box 11. The outer surface of the control bottom box 151 is fixedly connected to the middle of the inner cavity of the plane box 11, the top of the adapter filling plate 152 extends to the outside of the plane box 11 through the adapter groove, and the upper surface of the blocking sealing plate 153 and the top of the inner wall of the plane box 11 are squeezed against each other, and the inner cavity of the control bottom box 151 is fixedly connected to the inner cavity of the pressure-sensitive bottom cylinder 31 through the control wire, and the exhaust groove 17 is connected to the accommodating area where the control bottom box 151 is located. When the adapter filling plate 152 is pulled down by the control bottom box 151, the high-pressure gas will enter the accommodating area where the control bottom box 151 is located, and then be discharged through the exhaust groove 17, thereby realizing the pressure relief work.

[0036] The protection device 4 includes a long threaded rod 41, and the bottom end of the long threaded rod 41 is fixedly connected to a metal sealing disk 42. The outer surface of the metal sealing disk 42 is perfectly matched with the caliber of the pressure zone 16. When the metal sealing disk 42 is inserted into the pressure zone 16, the top area of ​​the force sliding disk 33 is sealed. At this time, the turbocharger continues to pressurize, and the pressure will not act on the upper surface of the force sliding disk 33, thereby keeping the data measured by the pressure-sensitive bottom cylinder 31 unchanged. The upper part of the outer surface of the protection device 4 is rotatably connected to a twisting device 5. The outer surface of the long threaded rod 41 is threadedly connected to the inner wall of the guide bolt sleeve 25. The bottom end of the long threaded rod 41 extends to the interior of the upper closure shell 23, and the top end of the signal wire 34 extends to the outside of the long threaded rod 41, and the outer surface of the signal wire 34 is fixedly connected to the inner wall of the long threaded rod 41.

[0037] The twisting device 5 includes a threaded rod sleeve 51, and the front and rear sides of the inner cavity of the threaded rod sleeve 51 are symmetrically provided with engaging wheels 53, and the axis of the inner cavity of the engaging wheels 53 is symmetrically provided with a torque motor 54 through a control rod, and the top of the inner cavity of the threaded rod sleeve 51 is evenly provided with a receiving end 52, and the front and rear sides of the threaded rod sleeve 51 are symmetrically provided with an adjustment rod 55, and the bottom end of the adjustment rod 55 is fixedly connected with a control tensioner 56. The bottom end of the control tensioner 56 is fixedly connected to the outer surface of the upper closed shell 23, the outer surface of the engaging wheel 53 is rotatably connected to the upper part of the outer surface of the long threaded rod 41, and the middle part of the inner wall of the threaded rod sleeve 51 is sleeved with the outer surface of the long threaded rod 41.

[0038] When performing the detection work, the turbocharger stops pressurizing after pressurizing to a certain level. At this time, the interior of the upper sealing shell 23 is in a high-pressure state. Then the twisting device 5 controls the long threaded rod 41 to rotate clockwise along the guide bolt sleeve 25, and gradually pushes the metal sealing disk 42 downward. At this time, the metal sealing disk 42 is inserted into the interior of the pressure zone 16 to seal the top area of ​​the force sliding disk 33. Then the pressure on the force sliding disk 33 is constant, so the pressure value of the pressure-sensitive bottom cylinder 31 here will not change. If the verticality of the pressure-sensitive bottom cylinder 31 changes at this time, it means that there is an air leakage problem inside the pressure zone 16 here. Therefore, the distorted data obtained by the turbocharger is not necessarily a problem with the turbocharger itself. It is necessary to eliminate the system failure of the device and perform the test again.

[0039] The threaded rod sleeve 51 drives the long threaded rod 41 to rotate through the interlocking wheels 53 on both sides. At the same time, in order to ensure that the threaded rod sleeve 51 can move vertically synchronously with the long threaded rod 41, the control tensioners 56 on both sides will pull the threaded rod sleeve 51 to move by adjusting the pull rod 55, ensuring that the interlocking wheels 53 can always fit the outer surface of the long threaded rod 41 to perform torsion control.

[0040] Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without creative work should fall within the scope of protection of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention are implemented according to the conventional means in the field unless otherwise specified and limited.
