[0033] like Figure 1 and 2 As shown, this embodiment discloses a stator-rotor press-fitting tool, characterized in that it is used to assemble a rotor assembly 10 and a stator assembly 20, wherein the rotor assembly 10 includes a rotor body 101 and a rotor connection assembly 102 disposed on the rotor body 101, and the rotor connection assembly 102 includes an end cover, wherein the end cover and the rotating shaft of the rotor body 101 are connected through a bearing. The stator assembly 20 includes a housing and a stator disposed in the housing, and after the rotor assembly 10 and the stator assembly 20 are assembled, the housing and the end cover are fixedly connected, and can be specifically connected by bolts or screws.

[0034] The stator and rotor press-fitting tooling includes a frame 1, a clamping assembly 2, a tray 3 and a driving member 4. The frame 1 includes a sliding rod 11, a workbench 13 and a mounting plate 12, and the two ends of the sliding rod 11 are respectively fixed on the workbench 13 and the mounting plate 12. The clamping assembly 2 is arranged on the frame 1, and specifically, the clamping assembly 2 is a three-jaw chuck, and a limit block 121 is arranged on the mounting plate 12, and the three-jaw chuck is installed on the limit block 121 of the mounting plate 12. The clamping assembly 2 is used to clamp the rotating shaft of the rotor body 101 so that the rotor assembly 10 is temporarily fixed on the frame 1.

[0035] The tray 3 is slidably disposed on the sliding rod 11, and a limiting portion is disposed on the tray 3, and the limiting portion is coaxially disposed with the clamping assembly 2. Specifically, a positioning block 31 is disposed on the tray 3, and the limiting portion is a positioning groove 311 disposed on the positioning block 31. The stator assembly 20 is mounted on the limiting portion, so that the stator assembly 20 and the rotor assembly 10 can be coaxial, which is convenient for subsequent assembly.

[0036] A limit assembly is provided on the tray 3, and the limit assembly is used to clamp the stator assembly 20. Specifically, the limit assembly includes at least two elastic limit members 32, which are arranged around the stator assembly 20, and the elastic limit members 32 can press against the outer wall of the stator assembly 20. In this embodiment, there are two elastic limit members 32, which are respectively located on the left and right sides of the positioning block 31. There are two sliding rods 11, which are respectively located on the left and right sides of the positioning block 31, so that the movement of the tray 3 is relatively stable, and the stator assembly 20 and the rotor assembly 10 will not be eccentric, resulting in inability to assemble.

[0037] The driving member 4 is disposed on the frame 1, and the output end of the driving member 4 is connected to the tray 3. The driving member 4 is used to drive the tray 3 to approach or move away from the clamping assembly 2 so that the rotor assembly 10 and the stator assembly 20 are assembled.

[0039] Assembly process: 1. The shaft head of the rotating shaft of the rotor assembly 10 passes through the center of the positioning block 31 and is clamped in place by the clamping assembly 2. 2. Place the stator assembly 20 in the positioning groove 311 of the positioning block 31, with the stop end of the casing facing upward, and then the two elastic limit members 32 cooperate to clamp the casing. 3. Start the driving member 4 so that the driving member 4 drives the tray 3 to move upward along the sliding rod 11 to assemble the stator assembly 20 and the rotor assembly 10. 4. After the casing and the end cover are pressed into place, the clamping assembly 2 no longer clamps the rotating shaft, and the driving member 4 is started again so that the driving member 4 drives the tray 3 to move downward. The rotor assembly 10 is transported to the workbench 13 along with the stator assembly 20, and then the elastic limit members 32 are opened to complete the pressing of the stator assembly 20 and the rotor assembly 10.
