Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-8 The present invention provides a technical solution: a turbocharger housing visual inspection device is to inspect the turbocharger housing (hereinafter referred to as the housing) by driving a corresponding structure through a detection system, and the corresponding structure includes a positioner 1 for fixing the turbocharger housing, and the positioner 1 includes a frame 2, and the upper areas of the columns on both sides of the frame 2 are both installed with a first motor 3, and the output end of the first motor 3 is fixedly installed with an adjustment frame 4, and the bearing area of ​​the adjustment frame 4 is a hollow frame structure, and a support structure 5 is welded on the short diameter sides of the hollow frame structure, and the support structure 5 is fixedly connected to the output end of the first motor 3, and a first rail 6 is horizontally fixedly installed on the top of the long diameter sides of the hollow frame structure, and two groups of housing alignment components 7 are slidably connected on the first rail 6. The function of the alignment component 7 is to limit the housing by interactively fixing each other, so that the housing can be detected in all directions. Compared with the fixed limiting position, the use of the alignment component 7 can also make the restricted area of ​​the housing detectable; The two sets of alignment components 7 have a difference in the position of the limiting structure. The two sets of alignment components 7 both include two sliding supports 8 slidably connected to the first rail 6, a bearing rod 9 is arranged between the two sliding supports 8, a support plate 10 is welded on the surface of the bearing rod 9, a second motor 11 is fixedly installed on the side wall of one of the sliding supports 8, an output end of the second motor 11 is fixedly connected to one end of the bearing rod 9, and the other end of the bearing rod 9 is bearing-connected to the other sliding support 8; The support plate 10 is used to fix and limit the housing, and only one housing is tested on the same positioner 1 at the same time; In this embodiment, the detection system drives the first motor 3 to drive the adjustment frame 4 to rotate, the adjustment frame 4 rotates to drive the first track 6 to rotate, the first track 6 rotates to drive the sliding support 8 to rotate, the sliding support 8 rotates to drive the bearing rod 9 to passively rotate, the bearing rod 9 passively rotates to drive the support plate 10 to rotate, and finally drives the shell to rotate. The purpose of this process is to facilitate the disassembly and assembly process of the shell by adjusting the support plate 10 to rotate at different angles; The top surface of the support plate 10 of one group of alignment components 7 is provided with a clamping component 12 along the short diameter sides of the hollow frame structure, and the top surface of the support plate 10 of the other group of alignment components 7 is provided with a clamping component 12 along the long diameter sides of the hollow frame structure. The clamping component 12 includes a side plate 13 fixedly mounted on the top surface of the support plate 10, two symmetrical second rails 14 are mounted on the side walls of the side plate 13, a clamping plate 15 is slidably connected to the second rail 14, and two telescopic rod structures 16 are fixedly mounted on the side walls of the clamping plate 15. The telescopic rod structure 16 is a prior art structure, and its function is to be able to perform telescopic movement. A rubber sleeve is fixedly mounted at its end, and the rubber sleeve is used to increase the friction between the telescopic rod structure 16 and the shell, thereby improving the fixing and limiting effect. The clamping plate 15 is driven by the detection system to perform lifting and lowering movement along the second rail 14, thereby driving the telescopic rod structure 16 to perform lifting and lowering movement, and the telescopic rod structure 16 can also perform telescopic movement autonomously, and the fixed restriction of the shell is completed by the passive movement and autonomous movement of the telescopic rod structure 16; The shell is a prior art structure. In this embodiment, the shell is structurally split and described. The shell is divided into an upper shell 17 and a lower shell 21. A connecting structure 18 is provided between the upper shell 17 and the lower shell 21. The upper shell 17 further includes a first slot 19, and the lower shell 21 further includes a second slot 20. Ground rails 22 are arranged on both sides of the positioner 1, and a detection assembly 23 is arranged on the sliding surface of the ground rail 22. The detection assembly 23 includes a detection frame 24, and a third rail 25 is installed on the top of the detection frame 24. A fill light plate 26 is arranged on the third rail 25 for sliding. Two connecting mechanisms slidably connected with the third rail 25 are arranged at the bottom of the fill light plate 26, so that the fill light plate 26 can move on the third rail 25. A fill light is arranged at the bottom of the fill light plate 26, and the fill light is focused and illuminated downward to improve the detection accuracy. A mechanical arm 27 is installed in the area of ​​the bottom of the fill light plate 26 where the fill light is not arranged, and a visual The detection structure 28 and the mechanical arm 27 are structures of the prior art. The detection system drives the detection frame 24 to move along the ground rail 22, and then drives the mechanical arm 27 to move. The movement of the mechanical arm 27 drives the visual detection structure 28 to move, so that the visual detection structure 28 can detect the shells on the several positioners 1 below. By moving the visual detection structure 28 and increasing the number of positioners 1, the visual detection structure 28 is still running for detection during the period when the position on the positioner 1 can be changed, so that the visual detection structure 28 and the positioner 1 work alternately, thereby improving the working efficiency of the visual detection structure 28; The detection system drives the support plate 10 to rotate first, so that the support plate 10 rotates to a position where it is at an angle of 30-65 degrees to the ground. At this time, the shell is manually placed on the support plate 10, and then the support plate 10 is driven to rotate again to a state parallel to the ground, and the shell is now on the top surface of the support plate 10. At this time, the position of the shell is manually adjusted again, so that the shell is located in a preset area set on the top surface of the support plate 10. This preset area is set by drawing on the top surface of the support plate 10. The detection system drives the clamping plate 15 on the support plate 10 loaded with the shell to move along the second track 14 until it moves to the middle area of ​​the lower shell 21, and then drives the telescopic rod structure 16 to extend, and then drives the rubber sleeve to extend, and the lower shell 21 is fixed and restricted by the rubber sleeve. After the detection system drives the visual detection structure 28 to perform a back and forth detection on the shell, the position of the shell is changed, and a back and forth detection is performed again; The inspection process of the visual inspection structure 28 starts to move along the starting point of the ground rail 22 until it reaches the end of the ground rail 22. During the movement of the visual inspection structure 28, the first inspection is performed on the shell below. After reaching the end of the ground rail 22, the visual inspection structure 28 starts to reset. During the resetting process of the visual inspection structure 28, a second inspection can be performed. After completing the two inspections of the shell, the position of the shell is replaced and the remaining positions of the shell are inspected. The process of replacing the shell is that a shell is detected and completed on the first alignment component 7 on the same positioner 1. At this time, the sliding supports 8 of the two alignment components 7 move in opposite directions along the first track 6, increasing the spacing between the support plates 10 of the two alignment components 7, so that there is enough space between the two support plates 10 to complete the position replacement of the shell. Then the second motor 11 carrying the alignment component 7 of the shell is operated, driving the bearing rod 9 to rotate 90 degrees. The bearing rod 9 rotates 90 degrees to drive the support plate 10 to rotate 90 degrees. The support plate 10 rotates 90 degrees to drive the shell to rotate 90 degrees toward the direction of another group of alignment components 7. The support plate 10 of the other group of alignment components 7 rotates 90 degrees toward this side of the shell in the same process. At this time, the two support plates 1 0 is in a vertically parallel state, and then the detection system drives the sliding support 8 to move along the first track 6, so that the two support plates 10 move toward each other and gradually approach each other, until the clamping assembly 12 on the controlled support plate 10 reaches the two sides of the preset shell that are not fixed and restricted, and then drives the telescopic rod structure 16 of the clamping assembly 12 of this assembly to fix and restrict the middle area of ​​the upper shell 17 in the same process as above, and then withdraws the other two telescopic rod structures 16, and finally resets the support plate 10. At this time, the shell completes the position change on the two support plates 10, and the shell is inspected again by the visual inspection structure 28. This type of inspection can perform all-round inspection on the shell surface, avoiding the situation where blind spots, bends, and clamping points cannot be inspected; Two storage boxes 29 are arranged on one side of the positioner 1, and two delivery pipes arranged up and down are arranged between the two storage boxes 29, the upper layer is a first delivery pipe 30, and the lower layer is a second delivery pipe 31. Two first conduits 32 are arranged on the pipe of the first delivery pipe 30, and the two first conduits 32 are connected to the water storage bin 33. A first telescopic pipe structure 34 is arranged on the front wall of the water storage bin 33, and the first telescopic pipe structure 34 matches the first slot 19. A second conduit 35 is arranged on the pipe of the second delivery pipe 31, and the top pipe of the second conduit 35 is connected to the second telescopic pipe structure 36, and the second telescopic pipe structure 36 matches the second slot 20. A thickened glass bin 37 is arranged in the middle of the second conduit 35, and a scale is arranged on the side wall of the glass bin 37, and this scale is used to measure the liquid level; Rubber pads are installed at the ends of the first telescopic tube structure 34 and the second telescopic tube structure 36, so that the connection between the first telescopic tube structure 34, the second telescopic tube structure 36 and the housing is tightly sealed, and the subsequent detection accuracy is high; The first delivery pipe 30 and the second delivery pipe 31 are both connected to the storage box 29. The storage box 29 stores clean water. A pump is arranged in the water storage tank 33. The pump is used to transport the water in the storage box 29 to the water storage tank 33 through the first conduit 32, and then transport the water from the water storage tank 33 into the shell through the first telescopic pipe structure 34. A pump is arranged in the second conduit 35. The pump is used to transport the water in the shell to the second conduit 35 through the second telescopic pipe structure 36, and then transport the water to the glass chamber 37 through the second conduit 35 for observation. Intelligent valves are provided at the top and bottom of the glass chamber 37, and the intelligent valves are regulated by the detection system; After the shell is manually adjusted so that it is located in a preset area set on the top surface of the support plate 10, the first slot 19 of the shell is aligned with the first telescopic tube structure 34, and the second slot 20 is aligned with the second telescopic tube structure 36. The detection system drives the first telescopic tube structure 34 and the second telescopic tube structure 36 to extend, and the first telescopic tube structure 34 is embedded in the first slot 19, and the second telescopic tube structure 36 is embedded in the second slot 20. The pump quantitatively delivers a preset amount of water into the shell, and then the water in the shell is pumped into the glass bin 37 by the pumping machine. It is manually observed whether the amount of water in the glass bin 37 is consistent with the preset amount of the pump. If they are consistent, it means that there is no leakage in the shell. There are impurities such as debris inside the shell during the previous processing link, and the inside of the shell is cleaned by the process of detecting the leakage. A liquid level sensor may also be provided in the glass bin 37, and the liquid level sensor may be connected to the detection system to monitor the liquid level in the glass bin 37 in an automated manner; The above-mentioned detection process of the shell is to first detect the inside of the shell, and then drain the shell by driving the adjustment frame 4 to rotate, so that the water inside the shell flows out to reduce the weight of the shell, and prepare for the shell to change its position. The detection of the present invention is a comprehensive detection of the shell without dead angles, and its detection accuracy is high and more comprehensive.
