[0002] The new energy electric compressor is a device that can compress air, hydrogen, oxygen and other gases into high-pressure gas. The working principle is to use an electric motor to drive the compressor blades to rotate and compress the gas into high-pressure gas.

[0003] In automobile air-conditioning systems, new energy electric compressors can compress environmentally friendly refrigerants into high-pressure gases, providing sufficient cooling effects for automobile air conditioners. Compared with traditional automobile compressors, new energy electric compressors have higher energy efficiency and lower noise. In the logistics industry, new energy electric compressors can provide fuel cells with the high-pressure hydrogen required for hydrogen production, achieving green environmental protection. In the medical industry, new energy electric compressors can provide high-pressure oxygen for equipment such as ventilators and artificial heart-lung machines, providing effective treatment for patients.

[0004] As the core component of new energy electric compressors, the dynamic disc has extremely high requirements for its position profile, flatness and other dimensions. When processing the dynamic disc, problems such as deformation and repeated positioning errors will occur. Therefore, the processing of the dynamic disc is very difficult. At present, most industries use diaphragm chuck clamping shape to process the dynamic disc, but there will be disadvantages such as clamping deformation, unreliable clamping, and poor repeated positioning accuracy.

[0005] In order to solve the above problems, a moving disc machining fixture is designed.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to those skilled in the art.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] like Figures 1 to 4 As shown, a dynamic plate machining fixture comprises:

[0031] A base 1, on which a main body 2 is fixedly arranged;

[0032] The main body 2 is provided with a trapezoidal structure 21, and a pressing plate 4 is provided above the main body 2, and expansion sleeves 3 are provided on both sides of the trapezoidal structure 21;

[0033] The expansion sleeve 3 first clamps the movable disc, and the pressure plate 4 then presses the movable disc, and then the expansion sleeve 3 is relaxed to achieve the overall clamping of the movable disc.

[0034] A trapezoidal structure 21 is provided on the main body 2, expansion sleeves 3 are provided on both sides of the trapezoidal structure 21, a pressure plate 4 is provided above the main body 2, and the bottom of the main body 2 is fixed on the base 1. When the movable disk is clamped as a whole, the expansion sleeve 3 first presses the movable disk, and then the pressure plate 4 presses the movable disk, and then the expansion sleeve 3 is relaxed, and the movable disk is clamped in place as a whole. The expansion sleeve 3 limits the horizontal movement of the movable disk, and the pressure plate 4 limits the vertical movement of the movable disk. The expansion sleeve 3 has strong flexibility in clamping the movable disk, and the internal expansion positioning of the movable disk is realized by the expansion sleeve 3. The pressure plate 4 is pressed, and the movable disk is clamped firmly. The expansion sleeve 3 and the pressure plate 4 will not cause damage or deformation to the movable disk, thereby ensuring the quality of the movable disk after processing.

[0035] In this embodiment, a positioning seat 5 is fixedly disposed above the main body 2 , and the positioning seat 5 is correspondingly disposed on both sides of the expansion sleeve 3 .

[0036] A positioning seat 5 is also provided above the main body 2. The positioning seat 5 is correspondingly arranged on both sides of the expansion sleeve 3. After the expansion sleeve 3 realizes the internal expansion positioning of the movable disk, the positioning seat 5 moves as the expansion sleeve 3 is relaxed. At this time, the pressure plate 4 is pressed tightly. When the pressure plate 4 and the positioning seat 5 are seamlessly contacted, it means that the pressure plate 4 is pressed into place, and the relaxed expansion sleeve 3 moves to the specified position of the movable disk, realizing the restriction of the all-round movement of the movable disk. The movable disk is clamped in place, and the subsequent processing operation of the movable disk is carried out. The positioning seat 5 ensures the reliability of the clamping device.

[0037] In this embodiment, a corner cylinder 6 is further provided on one side of the main body 2, the lower end of the corner cylinder 6 is fixedly connected to the base 1, and the upper end of the corner cylinder 6 is connected to the moving plate.

[0038] A corner cylinder 6 is also provided on one side of the main body 2. The lower end of the corner cylinder 6 is fixedly connected to the base 1, and the upper end of the corner cylinder 6 is connected to the moving plate. The axial stroke is accurately controlled by the corner cylinder 6 to further tighten the moving plate, so that the clamping speed is fast and the positioning is accurate.

[0039] In this embodiment, a support block 7 is provided on the positioning seat 5, and the support block 7 is in contact with the bottom of the moving plate;

[0040] The portion of the support block 7 that contacts the bottom of the moving plate is configured as an arc-shaped structure 71 .

[0041] By arranging a support block 7 on the positioning seat 5, the support block 7 is in contact with the bottom of the moving disk, and the portion of the support block 7 in contact with the bottom of the moving disk is arranged as an arc structure 71. The support block 7 plays a certain supporting role on the moving disk, ensuring that the moving disk will not tilt during the clamping process, thereby affecting the clamping effect, and the contact portion is arranged as an arc structure 71, thereby reducing the damage and deformation effects on the moving disk.

[0042] In this embodiment, the positioning accuracy of the expansion sleeve 3 is controlled within 0.003.

[0043] The positioning accuracy of the expansion sleeve 3 used is within 0.003, which realizes high-precision positioning of the moving plate and improves the problem of poor repeated positioning accuracy.

[0044] In this embodiment, after the expansion sleeve 3 clamps the movable plate, pressure detection is performed; after the pressure plate 4 presses the movable plate, pressure detection is performed.

[0045] After the expansion sleeve 3 clamps the movable disc, a pressure test is required. After the pressure plate 4 clamps the movable disc, a pressure test is also required. The results of the two pressure tests respectively reflect the degree to which the expansion sleeve 3 clamps the movable disc and the pressure plate 4 clamps the movable disc. On the one hand, it ensures the clamping effect of the clamping device, and on the other hand, it protects the movable disc from deformation and damage due to the clamping pressure.

[0046] In this embodiment, a positioning surface airtightness monitoring device is also fixedly provided on the base 1 , and the positioning surface airtightness monitoring device is connected to the positioning seat 5 through an air pipe 8 .

[0047] By fixing a positioning surface airtight monitoring device (not marked in the figure) on the base 1, the positioning surface airtight monitoring device is connected to the positioning seat 5 through the air pipe 8. The positioning surface airtight monitoring device is used to improve the positioning accuracy of the positioning seat 5 and the expansion sleeve 3, thereby ensuring the reliability of the clamping of the clamping device.

[0048] In this embodiment, after the moving disk is clamped in place as a whole, the moving disk is processed and then the processed moving disk is subjected to anti-mis-assembly verification.

[0049] The processed moving discs are verified to prevent wrong installation, and the unqualified moving discs are recycled to ensure the quality of the exported moving disc products.

[0050] Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description are only for explaining the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which are within the scope of the present invention.
