[0027] like Figure 1 As shown, the transverse moving assembly 2 includes a transverse moving driving member 21 arranged on the vertical frame 1, a transverse moving slide rail 22, and a transverse moving plate 23 slidably arranged on the transverse moving slide rail 22. The transverse moving plate 23 is connected to the output end of the transverse moving driving member 21, and the transverse moving plate 23 is driven by the transverse moving driving member 21 to slide back and forth along the transverse moving slide rail 22. The lifting assembly 3 is arranged on the transverse moving plate 23, and the lifting assembly 3 includes a lifting driving member 31 arranged on the transverse moving plate 23. The output end of the lifting driving member 31 is connected to the lifting plate 32, and the lifting driving member 31 drives the lifting plate 32 to realize the lifting action. In this embodiment, the transverse moving driving member 21 and the lifting driving member 31 can adopt structures such as a motor screw mechanism and a motor screw slide, which belong to the existing conventional technology and will not be repeated here.

[0028] like Figure 1-2 As shown, a flip assembly 4 is provided on the lifting plate 32, and the flip assembly 4 includes a connecting plate 41 provided on the lifting plate 32, and an assembly support plate 42 is connected to one end surface of the connecting plate 41, and an active rotating member and a driven rotating member are provided on the assembly support plate 42. The active rotating member includes a first telescopic cylinder 43 and a transverse rack 44 slidably provided on the assembly support plate 42; the driven rotating member includes a rotating shaft 46 rotatably arranged on the assembly support plate 42, one end of the rotating shaft 46 is sleeved with a rotating gear 45, and the other end is connected to the clamping assembly 5 through a transmission plate 47; the rotating gear 45 and the transverse rack 44 are meshed with each other, and the transverse rack 44 is driven to reciprocate relative to the assembly support plate 42 by the first telescopic cylinder 43, so that the rotating shaft 46 is rotated synchronously, and the clamping assembly 5 is driven to rotate synchronously. Specifically, the first telescopic cylinder 43 is fixed on the assembly support plate 42, and a slide groove is provided on the end surface of the assembly support plate 42 which is away from the first telescopic cylinder 43. The extension direction of the slide groove is consistent with the extension direction of the push rod of the first telescopic cylinder 43. The push rod end of the first telescopic cylinder 43 is connected to one end of the transverse rack 44, so that the first telescopic cylinder 43 can drive the transverse rack 44 to move back and forth. The rotating shaft 46 is connected to the assembly support plate 42 through a bearing, the outer ring of the bearing is fixed on the assembly support plate 42, and the rotating shaft 46 is arranged on the inner ring of the bearing, so that the rotating shaft 46 can rotate relative to the assembly support plate 42. The rotation of the clamping assembly 5 is realized by the mutual engagement of the transverse rack 44 and the rotating gear 45, which effectively improves the turning accuracy, and the turning action can be completed during the clamping process, effectively improving the work efficiency and reducing the time of additional turning.

[0029] like Figure 1-2As shown, preferably, two sets of limit members 48 are arranged on the assembly support plate 42. The limit members 48 are symmetrically arranged on the radial two sides of the rotating shaft 46 with the axis of the rotating shaft 46 as the center. During the rotation of the rotating shaft 46, the transmission plate 47 can abut against the limit members 48 to control the rotation stop position of the rotating shaft 46 and ensure that the rotating shaft 46 always rotates 180°.

[0030] As Figure 1-3 shown, the clamping assembly 5 includes a mounting plate 51 fixed to the transmission plate 47, a clamping slide rail 52 arranged on the mounting plate 51, a first clamping member 53 and a second clamping member 54 slidably arranged on the clamping slide rail 52, and a linkage driving member for driving the first clamping member 53 and the second clamping member 54 to approach and separate from each other.

Preferably, end plates 57 are arranged at both ends in the extending direction of the clamping slide rail 52, and elastic members 58 are connected between the sides of the first clamping member 53 and the second clamping member 54 away from the partition plate 56 and the corresponding end plates 57 respectively to prevent the first clamping member 53 and the second clamping member 54 from disengaging from the clamping slide rail 52 when they move away from each other, and when the clamping action is completed, the elastic members 58 play a buffering role to prevent the clamping force of the first clamping member 53 and the second clamping member 54 from being too large and damaging the rotor.

The other end of the third link 554 intersects with the other end of the fourth link 555 and is movably hinged to the first clamping member 53, and the other end of the fifth link 556 intersects with the other end of the sixth link 557 and is movably hinged to the second clamping member 54. When the second telescopic cylinder 551 operates and its push rod extends, it pushes the second clamping member 54 to slide away from the partition 56, and the first clamping member 53 slides away from the partition 56 simultaneously under the action of the double diamond link member to realize the opening of the first clamping member 53 and the second clamping member 54; when the second telescopic cylinder 551 operates and its push rod retracts, it drives the second clamping member 54 to slide closer to the partition 56, and the first clamping member 53 slides closer to the partition 56 simultaneously under the action of the double diamond link member to realize the clamping of the first clamping member 53 and the second clamping member 54.

[0033] As Figure 1-3 shown in the figure, the first clamping member 53 includes a first support plate 531 slidably arranged on the clamping slide rail 52. On one side end face of the first support plate 531 away from the clamping slide rail 52, a first extension plate 532 is arranged. On one side end face of the first extension plate 532 close to the second clamping member 54, a first clamping cooperation part 533 is arranged; the second clamping member 54 includes a second support plate 541 slidably arranged on the clamping slide rail 52. On one side end face of the second support plate 541 away from the clamping slide rail 52, a second extension plate 542 is arranged. On one side end face of the second extension plate 542 close to the second clamping member 54, a second clamping cooperation part 543 is arranged. The clamping end faces of the first clamping cooperation part 533 and the second clamping cooperation part 543 are arranged in an arc structure to adapt to the shape of the rotor. The two clamping cooperation parts approach each other and act on the outer side wall of the rotor to clamp the rotor. Preferably, the first clamping cooperation part 533 and the second clamping cooperation part 543 have the same structure. In this embodiment, the clamping cooperation part is arranged as the first clamping plate 5331 and the second clamping plate 5332 arranged at intervals. The clamping end faces of the first clamping plate 5331 and the second clamping plate 5332 are arranged in an arc to adapt to the shape of the rotor and prevent damage to the rotor during the clamping process.
