Technical Field

[0001] The utility model relates to the technical field of turbochargers, in particular to a tool for torsionally tightening a rotor shaft and an impeller assembly. Background Art

[0002] The turbocharger is an important part of modern engineering technology. By optimizing the design and material selection, its potential shortcomings can be overcome and its performance advantages can be better utilized. The rotor shaft and impeller assembly is a common component, especially in turbines, pumps, fans and other rotating equipment. The design and manufacture of this combined component is critical to the performance and efficiency of the equipment.

[0003] At present, in the assembly and production process of turbochargers, there are mostly two methods to meet the torque requirements of the rotor shaft and impeller. Method one is to use a traditional torque wrench and an ordinary wrench (or a bench vise) together. The traditional method has a complicated operation process and low production efficiency. Secondly, the use of a bench vise or a universal tool for clamping is likely to cause clamping damage to the product. Method two is to use a specialized assembly line operation method, which has a higher production efficiency, but the degree of specialization of parts and tooling is high, and the universality between different models of products is poor. The replacement of tooling for product production switching is complicated and time-consuming. Therefore, a tooling for torque tightening of the rotor shaft and impeller assembly is proposed to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Reference Figure 1-Figure 3 The utility model provides an embodiment: a tool for torsion tightening of a rotor shaft and an impeller assembly, comprising a bottom plate 1, four corners of which are provided with mounting holes, and the bottom plate 1 is made of high-strength steel, and has high rigidity and durability to ensure that it will not be deformed or damaged during operation. Four corners of the bottom plate 1 are provided with mounting holes for fixing the entire tool on a workbench to provide a stable foundation, and both sides of the top of the bottom plate 1 are detachably connected with a sliding base 11, and the inner walls of both sides of the sliding base 11 are detachably connected with two screws 3.

[0022] A groove is provided on the surface of the sliding base 11, and a screw 3 can be adjusted in the groove so that the position of the sliding base 11 can be adjusted. A bracket 2 is fixedly connected to the top of the sliding base 11, and the bracket 2 can be stably supported by the sliding base 11. The inner walls on both sides of the bracket 2 are detachably connected with screws 4. Grooves are provided on both sides of the bracket 2, and the screws 4 can move through the grooves. The adjacent sides of the two brackets 2 are slidably connected with a limiting component for limiting subsequent components, and the limiting component includes a support plate 5, and the two sides of the support plate 5 are respectively slidably connected to the adjacent sides of the bracket 2.

[0023] The inner wall of screw 2 4 is threadedly connected to the outer wall of support plate 5, and screw 2 4 can drive support plate 5 to move between brackets 2. The top of base plate 1 is rotatably connected with sleeve interchangeable joint 6. A U-shaped groove is provided inside support plate 5, and the inner wall of U-shaped groove contacts with the outside of sleeve interchangeable joint 6. Sleeve interchangeable joint 6 can be limited by U-shaped groove, so that sleeve interchangeable joint 6 can be supported and U-shaped groove structure can realize quick placement and removal of sleeve interchangeable joint 6, thereby improving work efficiency.

[0024] A hexagonal sleeve 7 is riveted on the top of the sleeve interchangeable joint 6, and a rotor shaft 8 is fixedly connected to the outside of the sleeve interchangeable joint 6. The hexagonal sleeve 7 is used to cooperate with a torque wrench to achieve precise tightening of the rotor shaft 8 and subsequent components. The hexagonal sleeve 7 is made of high-hardness steel and can withstand high torque to ensure the stability of the tightening process. The outer top of the rotor shaft 8 is fixedly connected to an impeller 10, and the bottom of the impeller 10 is fixedly connected to a fixed sleeve shaft seal 9 for sealing the connection between the rotor shaft 8 and the impeller 10 to prevent air leakage and loss.

[0025] Working principle: First, the base plate 1 is made of high-strength steel, which provides high rigidity and durability to prevent deformation or damage during operation. The mounting holes of the base plate 1 enable the tooling to be firmly fixed on the workbench, providing a stable operating basis. The sliding base 11 is set on both sides of the base plate 1. Through the groove structure on its surface and the adjustment function of screw 13, the position of the sliding base 11 can be flexibly adjusted. This ensures the stable support of the bracket 2, so that the entire system can adapt to different operating requirements. The top of the bracket 2 can be accurately adjusted by screw 24. The design of these adjustment grooves ensures the accurate movement of the support plate 5, so that the subsequent components can be well restricted and positioned in actual operation. The U-shaped groove inside the support plate 5 contacts with the sleeve change joint 6, which limits the lateral movement of the sleeve change joint and can be quickly placed and disassembled, greatly improving the work efficiency. The top of the sleeve change joint 6 is riveted with a hexagonal sleeve 7, which is made of high-hardness steel to ensure stability and accuracy under high torque operation. The hexagonal socket 7 cooperates with the torque wrench to achieve precise tightening of the rotor shaft 8, thereby ensuring the firmness and safety of the connection. The top of the rotor shaft 8 is fixedly connected to the impeller 10, and the bottom of the impeller 10 is connected to the fixed sleeve shaft seal 9, which effectively seals the connection between the rotor shaft 8 and the impeller 10 to prevent air leakage and loss, thereby ensuring the efficient operation and long-term stability of the system. Through these designs, the entire tooling not only has high rigidity and durability, but also can maintain stability in high-precision and high-efficiency operations, ensuring that the torque tightening process of the rotor shaft 8 and the impeller 10 assembly is accurate.
