Description

Technical Field

[0001] This utility model belongs to the technical field of impeller assembly table, and in particular relates to a CNC lifting impeller assembly table. Background Technology

[0002] The CNC lifting impeller assembly table is an advanced impeller assembly equipment that integrates CNC technology and adjustable lifting function. It is mainly used for the assembly, testing and balancing of precision impellers. The impeller assembly table is a professional work platform for assembling impellers and is commonly used in the manufacturing and maintenance of rotating machinery such as pumps, turbines and compressors.

[0003] In the process of using existing CNC lifting impeller assembly tables, the motor or pump body is not clamped and fixed. When assembling the impeller onto the motor or pump body, the interference fit between the impeller and the motor causes the motor to move, making it impossible to successfully install the impeller onto the motor in one go. Moreover, when the impeller is installed on the rotating shaft, it needs to be pressed down. Uneven force on the impeller can easily cause it to tilt, affecting its later use.

[0004] To address this, we provide a CNC lifting impeller assembly table. Utility Model Content

[0005] The purpose of this invention is to provide a CNC lifting impeller assembly table, which aims to solve the problems mentioned above.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0028] In this embodiment, the motor or pump body is placed inside the fixed ring seat 6, and the clamping arm 15 clamps the motor or pump body, keeping it at the center position of the fixed ring seat 6. The impeller is sleeved on the shaft of the motor or pump body. The hydraulic lifter 5 drives the pressure plate 8 to move downward, and the pressure plate 8 drives the pressure rod 23 to move downward. The four pressure rods 23 are in contact with the two sides of the upper end of the impeller, which can apply pressure evenly to the impeller, so that the impeller can be well stressed and sleeved on the shaft, avoiding the impeller tilting during installation and affecting its later use.

[0029] like Figure 2 and Figure 3 As shown, this embodiment provides a CNC lifting impeller assembly table. A clamping structure is provided between the clamping arm 15 and the fixed ring seat 6. The clamping structure includes a mounting block 9, which is fixedly installed on both sides of the lower end of the inner wall of the fixed ring seat 6. One end of the clamping arm 15 is rotatably connected to the mounting block 9. A pressure roller 17 is rotatably installed on one end of the clamping arm 15. A rotating screw 10 is rotatably installed on the upper end of the mounting block 9. The upper end of the rotating screw 10 is movably inserted through the outer side of the fixed ring seat 6 and is equipped with a meshing gear 11. A movable screw sleeve 14 is movably sleeved on the surface of the rotating screw 10. A movable support rod 16 is movably installed on one side of the movable screw sleeve 14. One end of the movable support rod 16 is movably connected to the clamping arm 15. An adjusting ring 7 is rotatably installed on the upper end of the fixed ring seat 6.
