Description

Technical Field

[0001] This invention relates to the field of turbocharger tooling technology, specifically a pressure shell assembly tooling. Background Technology

[0002] A turbocharger is essentially an air compressor that increases the intake air volume by compressing air. It uses the inertial force of the exhaust gas from the engine to drive a turbine in the turbine housing. The turbine, in turn, drives a coaxial impeller, which compresses the air supplied through the air filter and forces it into the cylinder. During the manufacturing process of the turbocharger's casing, tooling is used to clamp and limit its movement.

[0003] Tooling is a workpiece used to clamp and limit materials. Conventional tooling is equipped with simple cylinders and pressing heads to clamp the workpiece. However, when the surface of the workpiece is complex, such as the surface of the press shell being an irregular arc, it is difficult to ensure that the press is in the correct position during pressing, resulting in insufficient pressure during pressing and an insecure connection between the tooling and the workpiece. Summary of the Invention

[0004] The purpose of this invention is to provide a press shell assembly fixture to solve the problems mentioned in the background art. Conventional fixtures used for clamping and limiting workpieces are equipped with simple cylinders and press heads to clamp the workpieces. However, when the workpiece surface is complex, such as the press shell surface being an irregular arc surface, it is difficult to ensure that the press is in the correct position during press-fitting, resulting in insufficient pressure during press-fitting and an insecure connection between the fixture and the workpiece.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pressure shell assembly fixture, comprising a base plate, two legs mounted on the rear top of the base plate, a first cylinder and a second cylinder mounted on the end side of the legs, stroke slide rails mounted on the end side of the base plate near the first cylinder and the second cylinder respectively, stroke sliders mounted on the end side of the stroke slide rails, a right-angle pressure head fixed to the top of the stroke slider on the side of the second cylinder, a flat pressure head mounted to the top of the stroke slider on the side of the first cylinder, an angle plate fixed to the end corner of the base plate, a first displacement sensor mounted on the top of the angle plate, and a support plate mounted on the top right end of the base plate. Material sensors and workstation sensors are respectively installed on the top end wall of the support plate near the base plate. Columns are installed at the four corners of the top of the base plate. A top plate is installed on the top of each column. A top cylinder is installed in the middle of the top of the top plate. A middle plate is installed at the lower end of the top cylinder. A middle cylinder is installed at the bottom of the top plate. A lower plate is installed at the lower end of the middle cylinder. A sweeping dock is installed in the middle of the lower plate. A lower pressure plate is installed at the lower end of the lower plate. A middle pressure plate is installed at the bottom of the middle plate. Pressure sensors are installed between the stroke slide rail and the second cylinder and the first cylinder, respectively. A second displacement sensor is installed on the side end of the stroke slider.

[0006] Preferably, there are two legs, and the base plate and the legs are fixedly connected to each other, and the legs are fixedly connected to the first cylinder and the second cylinder respectively.

[0007] Preferably, both the first cylinder and the second cylinder are fixedly connected to the stroke slide rail via pressure sensors, and the stroke slider and the stroke slide rail are movably connected.

[0008] Preferably, the base plate is fixedly connected to the support plate and the column, and the top of the column is fixedly connected to the top plate.

[0009] Preferably, the top plate and the top cylinder are fixedly connected, while the middle cylinder and the lower plate are driven together.

[0010] Preferably, the middle plate and the lower plate are movably connected to the column, and the top cylinder is driven by the middle plate.

[0011] Preferably, the lower plate and the sweeping wharf are fixedly connected, and the lower plate and the lower pressure plate are also fixedly connected.

[0012] Preferably, the middle plate and the middle pressure plate are fixedly connected, and two pressure sensors are provided.

[0013] Preferably, two second displacement sensors are provided, and the second displacement sensors are fixedly connected to the stroke slider.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. This invention uses two legs to fix the first cylinder and the second cylinder to the base plate respectively. When the first cylinder and the second cylinder are running, two pressure sensors push the two stroke sliders to slide along two stroke slide rails respectively. The stroke slide rails are used to limit the stroke sliders, making the stroke sliders more stable and accurate during displacement. The top of the two stroke sliders is fixed with a right-angle pressure head and a flat pressure head respectively. After the right-angle pressure head and the flat pressure head are pushed and displaced, they press against the pressure shell end of the turbocharger, providing simple limiting and positioning of the pressure shell end. The pressure sensors are used to measure and obtain the pressure values ​​of the right-angle pressure head and the flat pressure head to prevent damage to the pressure shell.

[0016] 2. In this invention, the column is used to connect the top plate, and the support plate is used to support the pressure shell. The top cylinder and the middle cylinder on the end side of the top plate are operated to push the middle plate and the lower plate to move, so that the middle plate and the lower plate move down, and the middle pressure plate at the bottom of the middle plate and the lower pressure plate at the bottom of the lower plate are pressed against the top area of ​​the pressure shell, which is used for simple limiting and positioning of the top of the pressure shell.

[0017] 3. This invention uses the movable upper and lower plates of the column to make the middle and lower plates smoother and more stable during displacement. The scanning dock on the lower plate is used to scan the QR code on the pressure shell, which can bind the pressing force and the QR code in subsequent programs. The station sensor is used to detect whether the pressure shell is in the station, thereby improving the accuracy of clamping.

[0018] 4. This invention uses two second displacement sensors to detect the position of the right-angle pressure head and the flat pressure head, and a first displacement sensor to detect the position of the pressure shell. At the same time, it works with two material sensors to accurately sense the presence of the pressure shell, which facilitates the precise pressing of irregularly shaped pressure shells.

Material sensors 12 and workstation sensors 20 are respectively installed on the end walls of the base plate 1. Columns 13 are installed at the four corners of the top of the base plate 1. A top plate 14 is installed on the top of the column 13. A top cylinder 15 is installed in the middle of the top of the top plate 14. A middle plate 16 is installed at the lower end of the top cylinder 15. A middle cylinder 17 is installed at the bottom of the top plate 14. A lower plate 18 is installed at the lower end of the middle cylinder 17. A sweeping dock 19 is installed in the middle of the lower plate 18. A lower pressure plate 21 is installed at the lower end of the lower plate 18. A middle pressure plate 22 is installed at the bottom of the middle plate 16. Pressure sensors 23 are installed between the stroke slide rail 6 and the second cylinder 4 and the first cylinder 3 respectively. A second displacement sensor 24 is installed on the side of the stroke slider 5.

[0029] Two legs 2 are provided, and the base plate 1 and legs 2 are fixedly connected. Legs 2 are also fixedly connected to the first cylinder 3 and the second cylinder 4 respectively. Both the first cylinder 3 and the second cylinder 4 are fixedly connected to the stroke slide rail 6 via pressure sensors 23. The stroke slider 5 and the stroke slide rail 6 are movably connected. The two legs 2 fix the first cylinder 3 and the second cylinder 4 to the base plate 1 respectively. When the first cylinder 3 and the second cylinder 4 are running, the two pressure sensors 23 push the two stroke sliders 5... Do not slide along the two travel slide rails 6. The travel slide rails 6 are used to limit the travel slider 5, making the travel slider 5 more stable when it moves and the accuracy of the travel slider 5 is also higher. The top of the two travel sliders 5 are respectively fixed with right angle pressure head 7 and flat pressure head 8. After the right angle pressure head 7 and flat pressure head 8 are pushed and moved, they press against the pressure shell end of the turbocharger, which provides simple limit positioning for the pressure shell end. The pressure sensor 23 is used to measure and obtain the pressure value of the right angle pressure head 7 and flat pressure head 8 to prevent damage to the pressure shell.

[0030] The base plate 1 is fixedly connected to the support plate 11 and the column 13. The top of the column 13 is fixedly connected to the top plate 14. The top plate 14 and the top cylinder 15 are fixedly connected. At the same time, the middle cylinder 17 and the lower plate 18 are driven together. The column 13 is used to connect the top plate 14. The support plate 11 is used to support the pressure shell. The top cylinder 15 and the middle cylinder 17 on the end side of the top plate 14 are operated to push the middle plate 16 and the lower plate 18 to move, so that the middle plate 16 and the lower plate 18 move down, so that the middle pressure plate 22 at the bottom of the middle plate 16 and the lower pressure plate 21 at the bottom of the lower plate 18 are pressed against the top area of ​​the pressure shell, which is used for simple limiting and positioning of the top of the pressure shell.

[0031] The middle plate 16 and the lower plate 18 are movably connected to the column 13. At the same time, the top cylinder 15 is driven by the middle plate 16. The lower plate 18 and the scanning dock 19 are fixedly connected. The lower plate 18 and the lower pressure plate 21 are also fixedly connected. By moving the middle plate 16 and the lower plate 18 through the column 13, the middle plate 16 and the lower plate 18 can be moved more smoothly and stably. The scanning dock 19 on the lower plate 18 is used to scan the QR code on the pressure shell. The pressing force and the QR code can be bound in the subsequent program.

The second displacement sensors 24 are fixedly connected to the stroke slider 5. The positions of the right-angle pressure head 7 and the flat pressure head 8 are detected by the two second displacement sensors 24. The first displacement sensor 10 detects the position of the pressure shell. At the same time, two material sensors 12 are used to accurately sense the presence of the pressure shell, which facilitates the accurate pressing of irregularly shaped pressure shells.

[0033] In summary, this pressure shell assembly fixture, during use, uses two legs 2 to fix the first cylinder 3 and the second cylinder 4 to the base plate 1 respectively. When the first cylinder 3 and the second cylinder 4 are running, two pressure sensors 23 push the two stroke sliders 5 to slide along the two stroke slide rails 6 respectively. The stroke slide rails 6 are used to limit the stroke sliders 5, making the displacement of the stroke sliders 5 more stable and the displacement accuracy of the stroke sliders 5 higher. The top of the two stroke sliders 5 is fixed with a right-angle pressure head 7 and a flat pressure head 8 respectively. After the right-angle pressure head 7 and the flat pressure head 8 are pushed and displaced, they press against the pressure shell end of the turbocharger, providing simple limiting and positioning of the pressure shell end. The pressure sensor 23 is used to measure and obtain the pressure value of the right-angle pressure head 7 and the flat pressure head 8 to prevent damage to the pressure shell. The column 13 is used to connect to the top plate 14, and the support plate 11 is used to support the pressure shell. The top cylinder 15 and the middle cylinder 17 are located on the end of the top plate 14. The operation is used to push the middle plate 16 and the lower plate 18 to move, so that the middle plate 16 and the lower plate 18 move down, and the middle pressure plate 22 at the bottom of the middle plate 16 and the lower pressure plate 21 at the bottom of the lower plate 18 are pressed against the top area of ​​the pressure shell, which is used for simple limiting and positioning of the top of the pressure shell. The middle plate 16 and the lower plate 18 are moved by the column 13, so that the middle plate 16 and the lower plate 18 are more smooth and stable during displacement. The scanning dock 19 on the lower plate 18 is used to scan the QR code on the pressure shell, which can bind the pressing force and the QR code in subsequent programs. The station sensor 20 is used to detect whether the pressure shell is in the station, improving the accuracy of pressing and clamping. The positions of the right angle pressure head 7 and the flat pressure head 8 are detected by two second displacement sensors 24, and the position of the pressure shell is detected by the first displacement sensor 10. At the same time, two material sensors 12 are used to accurately sense whether the pressure shell exists, which facilitates the accurate pressing of irregularly shaped pressure shells.
