[0032] In an embodiment of the present application, the scroll end face alignment device includes a linear motion mechanism, a first annular rib 2, a second annular rib 3, an elastic member 4 and a pressing sleeve 5. The first annular rib 2 is fixedly arranged on the linear motion end 1 of the linear motion mechanism, the second annular rib 3 is movably mounted on the linear motion end 1, the elastic member 4 is arranged between the first annular rib 2 and the second annular rib 3, the pressing sleeve 5 is connected to the second annular rib 3, and the other end of the pressing sleeve 5 faces the scroll 7. In this way, the elastic member 4 is squeezed by the second annular rib 3 and the first annular rib 2 to form a flexible connection, and the pressing sleeve 5 can be evenly pressed on the base 710 to ensure that the end face of the scroll 7 will not be deflected when the scroll 7 is tightened, thereby avoiding workpiece defects caused by uneven clamping end face during processing of the scroll 7.
[0033] In one embodiment, please refer to Figure 1 and Figure 2 The elastic member 4 is a spring. As a commonly used elastic structure, the spring has the advantages of low cost, convenient assembly and disassembly, and easy maintenance.
[0034] In a specific embodiment, please refer to Figure 1 and Figure 2 There are multiple springs, and the multiple springs are evenly arranged along the circumference of the linear motion end 1.
[0035] In this way, the multiple springs cooperate with each other to apply uniform elastic force to various parts of the second annular rib 3, so that the pressing sleeve 5 presses the base 710 more evenly, thereby better aligning the end face of the scroll plate 7.
[0036] Exemplarily, the embodiment of the present application includes 12 springs, which are evenly arranged along the circumference of the linear motion end 1 .
[0037] In a more specific embodiment, the second annular rib 3 is provided with a groove corresponding to the spring, and one end of the spring is installed in the groove.
[0038] In this way, the end of the spring is installed in the groove and is not easy to fall off during use, thereby improving the structural stability.
[0039] Exemplarily, the second annular rib 3 of the embodiment of the present application is provided with 12 grooves corresponding to the 12 springs mentioned above.

[0045] In this way, the elastic member 4 always applies a certain pre-tightening force to the second annular rib 3 , and the pressing sleeve 5 will not deviate at will, so as to more accurately align the end face of the scroll plate 7 .
[0046] In a specific embodiment, see Figure 2 The third annular rib 6 is detachably mounted on the linear motion end 1 .
[0047] In this way, when the elastic member 4, the second annular rib 3 or the top pressure sleeve 5 connected to the second annular rib 3 is worn or damaged, the staff can easily replace the worn or damaged parts, thereby simplifying the scroll end face alignment device.
[0048] In another embodiment, please refer to Figure 1 and Figure 2 The second annular rib 3 and the top pressing sleeve 5 are an integrated structure.
[0049] By means of the above arrangement, no deviation will occur between the top pressing sleeve 5 and the second annular rib 3 , so that the end face of the scroll plate 7 can be aligned more accurately.
