[0002] Turbochargers are commonly used to improve the efficiency of internal combustion engines and thus increase their power. A turbocharger consists of a turbine with a turbine wheel and a compressor with a compressor wheel, with both impellers arranged on a common rotor shaft. The turbine is driven by the mass flow rate of exhaust gases from the connected internal combustion engine and in turn drives the compressor wheel.

[0003] The turbocharger housing is an important component of the turbocharger, such as... Figure 7 As shown, the turbocharger housing includes a housing body 29, which has an annular inner cavity. A connecting pipe 31 communicating with the annular inner cavity is provided on the side of the housing body 29. A circular through hole 30 is opened in the middle of the housing body 29. Three nodes 34 are arranged on the bottom edge of the housing body 29. A bracket 32 ​​is installed on one side of the housing body 29, and mounting holes 33 are opened on the bracket 32. A boss 35 is provided on one side of the connecting pipe 31. After the turbocharger housing is produced, the upper port of the circular through hole 30 and the opening of the connecting pipe 31 need to be processed. The position of the boss 35 also needs to be detected. Currently, there is no tooling specifically designed for turbocharger housings; they are simply clamped, which makes the position prone to wobbling and cannot guarantee processing accuracy and efficiency.

[0021] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.

[0022] The embodiments of this utility model relate to a high-efficiency machining fixture for dual-positioning of turbocharger pressure shells, such as... Figure 1-7 As shown, the fixture includes a base plate 1. Two machining stations are arranged side-by-side on the upper end of the base plate 1. Each machining station includes a central sleeve 2 and three support seats 3 arranged around the central sleeve 2. The central sleeve 2 is embedded in the upper end of the base plate 1, and its inner hole penetrates the lower end face of the base plate 1. The three support seats 3 are arranged in a triangle on the upper end of the base plate 1. Each support seat 3 has a support column 21 at its upper end. A clamping device 4 is installed on the outer side of each support seat 3 on the upper end of the base plate 1. A vertically arranged side sleeve 9 is installed on the right side of the central sleeve 2 on the upper end of the base plate 1. A pipe support device 5 is installed at the upper end of the tooling base plate 1 behind the central sleeve 2. The pipe support device 5 includes a support frame 12, a U-shaped support block 14, and a pipe cylinder 15. The support frame 12 is fixed to the upper end of the tooling base plate 1 and is in an inverted L-shape. A rectangular notch 13 is opened on one side of the upper end of the support frame 12. A U-shaped support block 12 that slides up and down is installed in the rectangular notch 13. An arc-shaped pipe fitting surface 16 is provided on both sides of the opening at the upper end of the U-shaped support block 12. The pipe cylinder 15 is vertically installed on the upper end of the tooling base plate 1. The piston rod of the pipe cylinder 15 is connected to the lower end of the U-shaped support block 12.

[0023] A lifting ring 8 is installed on the left front side and the right rear side of the tooling base plate 1. The lifting ring 8 facilitates the transportation of the entire tooling.

[0024] The clamping device 4 includes a clamping cylinder 17, a pressure plate 18, and a connecting plate 19. The clamping cylinder 17 is vertically mounted on the tooling base plate 1. A rotating seat 20 is mounted on the upper end of the clamping cylinder 17 on one side of the piston rod. A connecting plate 19 is rotatably mounted on each side of the rotating seat 20. The two connecting plates 19 are rotatably connected to the two sides of the middle part of the pressure plate 18, respectively. The piston rod at the upper end of the clamping cylinder 17 is rotatably connected to one end of the pressure plate 18. When clamping is required, the clamping cylinder 17 is activated, and the piston rod of the clamping cylinder 17 extends, causing one end of the pressure plate 18 to lift and the other end of the pressure plate 18 to move downward to achieve downward pressure.

[0025] The tooling base plate 1 has multiple side limiting devices 6 arranged around the central sleeve 2 at its upper end. Each side limiting device 6 includes a column 22 and a rubber column 23. A horizontally arranged fixing plate 25 is installed at the lower end of the column 22. The fixing plate 25 has an elongated through hole 26. Multiple fasteners 24 connected to the tooling base plate 1 are installed in the elongated through hole 26. A detachable rubber column 23 is installed at the upper end of the column 22. Both the rubber column 23 and the column 22 are cylindrical structures with the same diameter. The rubber column 23 is coaxially arranged with the column 22.

[0026] The column 22 and the rubber column 23 are connected and fixed by fasteners 24, which are generally bolts or screws. A through hole is opened in the middle of the upper end of the rubber column 23. The lower end of the fastener 24 passes through the through hole from top to bottom and is screwed to the column 22. The cap of the upper end of the fastener 24 presses against the upper end face of the rubber column 23.

[0027] The tooling base plate 1 has multiple lifting devices 7 arranged around the central sleeve 2 at its upper end. Each lifting device 7 includes a lifting cylinder 27 vertically mounted on the tooling base plate 1. A rubber head 28 is mounted on the piston rod at the upper end of the lifting cylinder 27. The product is lifted by controlling the rubber head 28 to move up and down through the lifting cylinder 27.

[0028] The tooling base plate 1 is located on the left side of the pipe support device 5 and a detection seat 10 is installed on the upper part of the detection seat 10. A detection pin 11 that slides laterally is installed on the upper part of the detection seat 10.

[0029] like Figure 1 and 2 As shown, this fixture is a dual-station fixture, which can process two products simultaneously.

[0030] Now, taking a single-station approach, firstly, the main body 29 of the pressure shell is placed along multiple side limiting devices 6. The pillars 21 of the three support seats 3 respectively abut against the three nodes 34 at the bottom edge of the main body 29. The circular through hole 30 in the middle of the main body 29 is engaged with the central sleeve 2. The mounting hole 33 on the bracket 32 ​​is engaged with the side sleeve 9, thus achieving the limiting support of the main body 29. Next, the clamping device 4 is activated. The piston rod of the clamping cylinder 17 extends, causing one end of the pressure plate 18 to lift and the other end of the pressure plate 18 to move downward and press against the upper end of the main body 29, thus fixing the main body 29. Then, the pipe cylinder 15 controls the U-shaped support block 14 to move upward, so that the pipe fitting surfaces 16 on both sides of the opening of the U-shaped support block 14 respectively support the two sides of the lower part of the connecting pipe 31, thus achieving the limiting support of the connecting pipe 31. Then, the detection pin 11 is slid laterally. If one end of the detection pin 11 can contact the boss 35, the position of the boss 35 is qualified; otherwise, it is unqualified. After the boss 35 is in the correct position, the workers perform fine grinding on the upper end of the circular through hole 30 and the opening of the connecting pipe 31. The waste material processed from the upper end of the circular through hole 30 falls out through the inner hole of the central sleeve 2.

[0031] After processing, the clamping device 4 is reset and the clamping is canceled. The rear pipe cylinder 15 controls the U-shaped support block 14 to move downward, so that the U-shaped support block 14 is separated from the connecting pipe 31. Finally, multiple lifting devices 7 are activated, and the lifting cylinder 27 controls the rubber head 28 to move upward to lift the product, making it easy to remove the product.

[0032] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0033] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0034] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
