Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of automobile accessory processing, especially to a turbine supercharger blade processing tool for automobile engine. BACKGROUND
[0002] The turbine supercharger blade processing tool for automobile engine is a special tool for accurately processing turbine supercharger blades. It is usually used for the fine processing of turbine supercharger blades after they are cast into shape. Although the existing turbine supercharger blade processing tool can ensure the turbine supercharger blades in fine processing (such as grinding and polishing), the spiral blade part of the turbine supercharger blades cast into shape is hollow and generally has no support. Therefore, when the grinding tool exerts force on the blade surface during grinding or polishing, the spiral blade part has no support and the structure strength of the blade in this area is relatively weak. When subjected to the grinding force, different parts of the blade are unevenly stressed, which may cause local deformation. For example, the blade root and tip parts may be twisted or bent due to relatively large stress, which makes the shape of the blade deviate from the design requirements and affects the aerodynamic performance and working efficiency of the turbine supercharger. SUMMARY
[0003] The utility model discloses a turbine supercharger blade processing tool for automobile engine to solve the problems in the prior art.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme:
[0005] A turbine supercharger blade processing tool for automobile engine comprises a table body, an oil tank connected to the table body, a plurality of vertical rods connected to the oil tank, a plurality of piston rods movably connected to the vertical rods, and a plurality of rubber blocks connected to one end of the piston rods.
[0006] Preferably, a screw rod is connected to the table body, a sleeve is threadedly connected to the screw rod, and a threaded sleeve is threadedly connected to the screw rod.
[0007] Preferably, a plurality of control valves are connected to the oil tank, one of the control valves is connected to a hydraulic pump, and a pressure gauge is connected to the oil tank.
[0008] Preferably, a mounting seat is connected to each corner of the table body.
[0009] Preferably, the plurality of rubber blocks are designed in a hemispherical shape.
[0010] Preferably, part of the threaded sleeve is designed in a hexagonal shape.
[0011] Preferably, a rubber pad is connected to the threaded sleeve.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. Through the cooperation of the platform, oil tank, vertical rods, piston rods, and rubber blocks, the shaft hole of the turbocharger blade is fixed by the through-screw for centered positioning. After fixing, the hydraulic pump and control valve continuously inject hydraulic oil into the oil tank. This causes the piston rods in the multiple sets of vertical rods in the oil tank to move upwards due to the increasing hydraulic oil. The multiple sets of piston rods, pushed by the hydraulic oil, contact different positions of the turbocharger blades, providing uniform support force to the blades. Especially for cast blades with hollowed-out helical blades, this uniform support effectively prevents deformation due to uneven force during processing. In operations such as grinding and polishing, uniform support helps maintain the original shape of the blades, ensuring the flatness and smoothness of the processed surface, reducing processing errors and scrap rates caused by deformation, and guaranteeing the quality of the finished product.
[0014] 2. By fitting the screw, threaded sleeve, sleeve, and platform, and according to the actual shaft hole diameter of the turbocharger blade, the sleeve of the corresponding size is threadedly connected to the screw. In this way, the sleeve is adapted to the shaft hole of the turbocharger blade, which makes it easy to position the turbocharger blade at the platform. And by using the threaded sleeve at the screw to abut against the top of the turbocharger blade, the turbocharger blade can be fixed. To a certain extent, it can facilitate the fixing of turbocharger blades of different specifications. Attached Figure Description

[0021] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0022] Embodiment 1, refer to Figures 1 to 5 A kind of automobile engine turbocharger blade processing frock, including table body 1, oil tank 2 is connected on table body 1, multiple groups of vertical rods 3 are connected at oil tank 2, multiple groups of vertical rods 3 are all connected with table body 1, piston rod 4 is movably connected in multiple groups of vertical rods 3, this movable connection mode allows piston rod 4 to move freely up and down in vertical rod 3, to realize the support and adjustment to blade, multiple groups of piston rod 4 one end are all connected with rubber block 5, by injecting hydraulic oil into oil tank 2, in this way, when the hydraulic oil in oil tank 2 is constantly increased, it will be injected into multiple groups of vertical rods 3, to further push piston rod 4 to move upwards, to contact support operation with different positions of turbocharger blade, can prevent blade from being deformed due to uneven force in processing process.
[0023] In this embodiment, the body 1 is connected with a screw 6, and the screw 6 is threadedly connected with a sleeve 8. The sleeve 8 has multiple different size specifications, which can be selected according to the actual booster blade shaft hole diameter. In operation, the selected sleeve 8 is threadedly connected with the screw 6, so that the sleeve 8 is accurately fitted with the booster blade shaft hole, thereby accurately positioning the booster blade on the body 1. This design greatly improves the adaptability of the tool to different specifications of blades, facilitating the installation and positioning operation of the blade. The screw 6 is threadedly connected with a threaded sleeve 7, and the oil tank 2 is connected with multiple sets of control valves 10. One set of control valves 10 is connected with a hydraulic pump 11, and the multiple sets of control valves 10 are key components for controlling the flow and pressure of hydraulic oil. The type of control valve 10 can be a solenoid valve or a manual valve, which is selected according to actual needs and operational convenience. One set of control valves 10 is connected with the hydraulic pump 11, which serves as a power source. The model of the hydraulic pump 11 and the control valve 10 is selected according to actual work, and the hydraulic pump 11 is responsible for injecting external hydraulic oil into the oil tank 2. During operation, the flow and pressure of hydraulic oil can be accurately adjusted by operating the control valve 10, thereby controlling the rising speed and support force of the piston rod 4. This precise control capability enables the tool to adapt to blades of different shapes, sizes, and processing requirements, ensuring that the blade is always subjected to appropriate support force during processing. The oil tank 2 is connected with a pressure gauge 13, which monitors the pressure of hydraulic oil in the oil tank 2 in real time. The operator can intuitively understand the working state of the hydraulic system according to the pressure value displayed by the pressure gauge 13, and timely adjust the control valve 10 to ensure that the hydraulic oil pressure is within a safe and effective range. The presence of the pressure gauge 13 improves the reliability and safety of the entire hydraulic system, avoiding tool failure or blade processing quality problems caused by excessively high or low pressure. The body 1 is connected with mounting seats 12 at four corners, which are used to install the entire processing tool on the workbench or other fixed equipment. The multiple sets of rubber blocks 5 are designed in a hemispherical shape, which has unique advantages. The hemispherical surface can better fit the curved surface of the blade. Regardless of the curvature of the blade surface, the rubber block 5 can adaptively contact the blade within a certain range, providing stable and uniform support force, while avoiding scratching or damaging the blade surface during support. The threaded sleeve 7 is designed with a hexagonal block, and the threaded sleeve 7 is connected with a rubber pad 9. The hexagonal block design facilitates the operator to use tools to rotate the threaded sleeve 7. The rubber pad 9 connected to the threaded sleeve 7 plays an important role in clamping the blade. When the threaded sleeve 7 is connected with the screw 6 and rotated, the rubber pad 9 will gradually approach the blade tip as the threaded sleeve 7 moves, and finally tightly fit with the blade tip. The material of the rubber pad 9 has certain elasticity and friction, which can provide sufficient clamping force to ensure that the blade does not shift or loosen during processing, and can also avoid hard damage to the blade tip, protecting the integrity of the blade.
[0024] The working principle of the embodiment: in use, first, according to the shaft hole size of the actual supercharger blade, the sleeve 8 is threadedly connected with the screw rod 6, the connection is completed, the supercharger blade is placed at the sleeve 8, the supercharger blade can be positioned on the table body 1 due to the adaptation of the sleeve 8 and the shaft hole of the supercharger blade, then the threaded sleeve 7 is connected with the screw rod 6, and the rubber pad 9 is driven by the threaded sleeve 7 to contact the top end of the supercharger blade, so that the supercharger blade can be fixed on the table body 1, then the hydraulic pump 11 is matched with the control valve 10, the external hydraulic oil is injected into the oil tank 2, with the continuous increase of the hydraulic oil in the oil tank 2, according to the Pascal law, a plurality of piston rods 4 can contact and support the supercharger blade at different height positions, so that the spiral blade part of the supercharger blade can be protected to ensure the processing stability of the supercharger blade.
[0025] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
