Description
Technical Field
[0001] This utility model relates to the field of turbine housing inspection technology, specifically, it is a comprehensive inspection tooling for turbine housing exhaust channels. Background Technology
[0002] The exhaust passage on the outer wall of the turbine housing needs to be connected to the exhaust pipe during actual turbine housing application. Furthermore, the position of the intake manifold connector plate on the turbine housing, and the accuracy of its outer edge U-shaped groove, also need to be checked to prevent misalignment of the U-shaped groove from affecting the connection with the intake manifold. Additionally, the outer wall of the turbine housing also has threaded mounting holes for installing other external components; their position and outline also need to be checked.
[0003] Therefore, based on manual inspection, the key to improving the production efficiency of automotive parts lies in how to efficiently and accurately inspect the aforementioned turbine housing layout and exhaust passage. Utility Model Content
[0004] The purpose of this utility model is to provide a comprehensive inspection tooling for the turbine housing exhaust channel, so as to achieve the goal of simultaneously inspecting the turbine housing exhaust channel while manually inspecting the mounting holes on the outer wall of the turbine housing.
[0005] To achieve the above objectives, the present invention employs the following technical means:
[0006] A comprehensive inspection fixture for turbine housing exhaust passage includes a workbench, a fixed platform mounted on the top surface of the workbench, the fixed platform being used to position the intake manifold connecting plate of the turbine housing, an exhaust passage position contour detection mechanism, an intake manifold connecting plate U-shaped groove position contour detection mechanism, and a housing external mounting hole position detection mechanism mounted around the fixed platform on the workbench, and a clamping mechanism is also mounted on the top surface of the workbench on the side of the fixed platform.
[0007] The housing external mounting hole position detection mechanism has a vertically penetrating sliding channel. A threaded hole detection rod is slidably installed in the sliding channel. The bottom end of the threaded hole detection rod is set towards the outer wall of the turbine housing and is used to detect the vertically set external mounting hole on the outer wall of the turbine housing. The inner wall of the sliding channel and the outer wall of the threaded hole detection rod are in frictional contact.
[0008] Preferably, the fixing platform includes a placement platform for holding the intake manifold connector plate, and a horizontal pressure block is constructed on the top surface of one long side of the placement platform. The horizontal pressure block abuts against the top surface of the intake manifold connector plate, and the pressing mechanism is located on the side of the placement platform opposite to the horizontal pressure block.
[0009] Furthermore, a horizontal push rod mechanism is installed on the worktable. The horizontal push rod mechanism is located on the side of the placement platform opposite to the horizontal pressure block. The pushing end of the horizontal push rod mechanism moves toward the side of the horizontal pressure block, and the pushing end of the horizontal push rod mechanism abuts against the side wall of the intake manifold connecting plate.
[0010] Furthermore, the top surface of the placement platform is constructed with anti-slip textures.
[0011] Furthermore, the air outlet channel position contour detection mechanism includes a mounting platform installed on the workbench. The mounting platform has a sliding channel that extends through the turbine housing air outlet channel. A rotating rod is slidably installed in the sliding channel. A detection disk is coaxially installed on one end of the rotating rod facing the turbine housing. A detection block extending into the turbine housing air outlet channel is constructed on the side of the detection disk facing the turbine housing. The side contour of the detection block matches and fits the inner wall of the turbine housing air outlet channel.
[0012] Furthermore, the intake manifold connector U-groove position contour detection mechanism includes a support block installed on the top surface of the workbench. The support block is located on one long side of the fixed platform. The support block has a moving channel that extends through the U-groove of the side wall of the intake manifold connector. A calibration rod is slidably installed in the moving channel. The extension direction of the moving channel is parallel to the vertical extension direction of the U-groove of the side wall. The bottom end of the calibration rod is fitted against the inner wall of the U-groove of the side wall.
[0013] Furthermore, the housing external mounting hole position detection mechanism includes a positioning platform mounted on the workbench, the sliding channel is located on the top surface of the positioning platform, the outer wall of the threaded hole detection rod is constructed with a limiting groove along its axis, and a bolt is installed on the side wall of the positioning platform, with one end of the bolt extending into the sliding channel and embedded in the limiting groove.
[0014] This utility model has the following beneficial effects during use:
[0015] When inspecting the turbine housing, the intake manifold connector plate is first placed flat on a fixed platform, and a clamping mechanism is used to ensure a tight fit between the connector plate and the platform. The threaded mounting holes on the outer wall of the turbine housing are positioned upwards, directly aligned with the sliding channel on the housing mounting hole position detection mechanism. The threaded hole detection rod is then inserted into the sliding channel, allowing it to slowly move downwards under its own weight and friction with the sliding channel. During this downward movement, the exhaust channel position contour detection mechanism and the intake manifold connector plate U-groove position contour detection mechanism can be operated to detect the contour and position of the turbine housing's exhaust channel and the U-groove on the side of the intake manifold connector plate, respectively. The friction between the inner wall of the sliding channel and the threaded hole detection rod can be adjusted to regulate the rod's descent speed. This allows the entire inspection process to simultaneously inspect the turbine housing mounting threaded holes and the exhaust channel and intake manifold connector plate U-groove, significantly improving the efficiency of the comprehensive turbine housing exhaust channel inspection.

[0026] Please refer to Figures 1 to 3 As shown, a comprehensive testing fixture for the turbine housing exhaust passage includes a workbench 1. A fixed platform 2 is installed on the top surface of the workbench 1. The fixed platform 2 is used to position the intake manifold connecting plate of the turbine housing. An exhaust passage position contour detection mechanism 3, an intake manifold connecting plate U-shaped groove position contour detection mechanism 4, and a housing external mounting hole position detection mechanism 5 are installed around the fixed platform 2 on the workbench 1. A clamping mechanism 6 is also installed on the top surface of the workbench 1 on the side of the fixed platform 2.
[0027] The housing external mounting hole position detection mechanism 5 is constructed with a vertically penetrating sliding channel. A threaded hole detection rod 7 is slidably installed in the sliding channel. The bottom end of the threaded hole detection rod 7 is set towards the outer wall of the turbine housing and is used to detect the vertically set external mounting hole on the outer wall of the turbine housing. Here, the external mounting hole refers to the mounting threaded hole used to install external equipment such as temperature sensors and other components of the turbine housing. The inner wall of the sliding channel rubs against the outer wall of the threaded hole detection rod 7.
[0028] Thus, when inspecting the turbine housing, the intake manifold connector plate of the turbine housing is first placed flat on the fixed platform 2, and the clamping mechanism 6 is used to ensure that the intake manifold connector plate is tightly fitted to the fixed platform 2, so that the mounting threaded hole on the outer wall of the turbine housing is facing upward and aligned with the sliding channel on the housing external mounting hole position detection mechanism 5. Then, the threaded hole detection rod 7 is placed into the sliding channel, allowing the threaded hole detection rod 7 to gradually and slowly move downward under its own weight and while rubbing against the sliding channel. During the gradual and slow downward movement of the threaded hole detection rod 7, the exhaust passage position contour detection mechanism 3 and the intake manifold connector plate U-shaped groove position contour detection mechanism 4 can be operated to detect the contour and position of the exhaust passage of the turbine housing and the U-shaped groove on the side of the intake manifold connector plate, respectively. The friction between the inner wall of the sliding channel and the threaded hole detection rod 7 can be adjusted to regulate the falling speed of the threaded hole detection rod 7. This allows the entire inspection process to simultaneously complete the inspection of the turbine housing installation threaded hole, as well as the inspection of the exhaust channel and the U-groove of the intake manifold connecting plate, significantly improving the efficiency of the comprehensive inspection of the turbine housing exhaust channel.
[0029] Furthermore, the fixed platform 2 includes a placement platform 21 for holding the intake manifold connecting plate. A horizontal pressure block 22 is constructed on the top surface of one long side of the placement platform 21. The horizontal pressure block 22 abuts against the top surface of the intake manifold connecting plate. The pressing mechanism 6 is located on the side of the placement platform 21 opposite to the horizontal pressure block 22.
[0030] Furthermore, a horizontal push rod mechanism 8 is installed on the workbench 1. The horizontal push rod mechanism 8 is located on the side of the placement platform 21 opposite to the horizontal pressure block 22. The pushing end of the horizontal push rod mechanism 8 moves toward the side of the horizontal pressure block 22, and the pushing end of the horizontal push rod mechanism 8 abuts against the side wall of the intake manifold connecting plate.
[0031] Therefore, when assembling the turbine housing using the fixed platform 2, the horizontal pressure block 22 and the clamping mechanism 6 act on the top surface of the turbine housing intake manifold connecting plate, thereby limiting the turbine housing in the vertical direction. Then, by installing limiting blocks on the top surface of the placement platform 21, the other two sides of the turbine housing intake manifold connecting plate can be clamped, thereby limiting the turbine housing in the horizontal direction.
[0032] Moreover, the horizontal push rod mechanism 8 can further improve the stability of the turbine housing on the fixed platform 2.
[0033] Furthermore, the top surface of the placement platform 21 has anti-slip texture.
[0034] Furthermore, the air outlet channel position contour detection mechanism 3 includes a mounting platform 31 installed on the workbench 1. The mounting platform 31 has a sliding channel that extends through the turbine housing air outlet channel. A rotating rod 32 is slidably installed in the sliding channel. A detection disk 33 is coaxially installed on one end of the rotating rod 32 facing the turbine housing. A detection block 34 extending into the turbine housing air outlet channel is constructed on the side of the detection disk 33 facing the turbine housing. The side contour of the detection block 34 matches and fits the inner wall of the turbine housing air outlet channel.
[0035] Thus, when inspecting the outlet end of the turbine housing, the operator pushes the rotating rod 32 to allow the detection block 34 to extend into the turbine housing, and then operates the rotating rod 32 to rotate, thereby using the detection block 34 to inspect the inner wall of the turbine housing.
[0036] Furthermore, the intake manifold connecting plate U-shaped groove position contour detection mechanism 4 includes a support block 41 installed on the top surface of the workbench 1. The support block 41 is located on one long side of the fixed platform 2. The support block 41 has a moving channel that passes through the side wall U-shaped groove of the intake manifold connecting plate. A calibration rod 42 is slidably installed in the moving channel. The extension direction of the moving channel is parallel to the vertical extension direction of the side wall U-shaped groove. The bottom end of the calibration rod 42 is fitted against the inner wall of the side wall U-shaped groove.
[0037] Thus, when it is necessary to detect the position of the U-shaped groove of the intake manifold connecting plate, simply push the calibration rod 42 downwards. If the end of the calibration rod 42 can be inserted into the U-shaped groove on the side wall, it means that the U-shaped groove is in a qualified state.
[0038] Furthermore, in order to facilitate the adjustment of the falling speed of the threaded hole detection rod 7, the housing external hole position detection mechanism 5 includes a positioning platform installed on the worktable 1, the sliding channel is provided on the top surface of the positioning platform, the outer wall of the threaded hole detection rod 7 is constructed with a limiting groove 9 along its axis, and a bolt 10 is installed on the side wall of the positioning platform, one end of the bolt 10 extends into the sliding channel and is embedded in the limiting groove 9.
[0039] Thus, when bolt 10 is tightened, threaded hole detection rod 7 is compressed, and its descent speed under its own gravity will decrease; conversely, its descent speed can increase when bolt 10 is tightened.
[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
