The movable shaft 304 has a diameter smaller than the inner diameter of the hollow shaft 303 so that the movable shaft 304 can be movably inserted into the hollow structure of the hollow shaft 303. The telescopic driving mechanism 305 is fixedly installed on the clamping bracket 301, such as a cylinder, and the output end of the telescopic driving mechanism 305 is connected with the right end of the movable shaft 304, so that the movable shaft 304 can perform axial telescopic movement in the hollow shaft 303 under the driving of the telescopic driving mechanism 305.

The outer side of the hollow shaft 303 is provided with a plurality of clamping blocks 306, for example, 3 clamping blocks 306 are uniformly distributed in the same circumferential surface taking the axis of the hollow shaft 303 as the center, the clamping blocks 306 are all in long strips and parallel to the hollow shaft 303, and meanwhile, the side wall of the clamping block 306 facing away from the hollow shaft 303 is configured to be matched with the inner side wall of the stator to be clamped, namely, the side wall is arc-shaped. In this embodiment, each clamping block 306 is connected to the side wall of the hollow shaft 303 through two parallel support links 307, and at the same time, each clamping block 306 is connected to the movable shaft 304 through a movable link 308, so that when the movable shaft 304 moves telescopically relative to the hollow shaft 303, it can change the distance between the clamping block 306 and the hollow shaft 303 through the movable link 308, while the support links 307 are used to preserve the state of being parallel to each other between the clamping block 306 and the hollow shaft 303.

At the same time, a fixed ring 309 is fixedly mounted on the movable shaft 304, and the movable link 308 to which each clamping block 306 is connected is also connected to the movable shaft 304 via the fixed ring 309. In this embodiment, because of the arrangement of the support link 307 and the movable link 308, in order to prevent the movable shaft 304 from rotating along with the hollow shaft 303, a connecting sleeve (not shown in the figure) is connected between the output end of the telescopic driving mechanism 305 and the movable shaft 304 to eliminate torque, for example, one end of the connecting sleeve is fixedly connected with the output end of the telescopic driving mechanism 305 through a key or a pin, an inwardly protruding boss is arranged on the inner side wall of the other end of the connecting sleeve, and a movable block is arranged in a space on the right side of the boss, and the diameter of the movable block is larger than the inner diameter of the boss, so that the movable block cannot fall off from the connecting sleeve, and then the right end of the movable shaft 304 is fixedly connected with the movable block therein through a screw.

It will be appreciated that the left side of the housing 311 of the clamping device 300 is provided with a through hole so that the left side of the hollow shaft 303 protrudes into the protective casing 101, and that the movable shaft 304, the clamping block 306, the support link 307 and the movable link 308 are all located within the protective casing 101.

The clamping device 300 works on the principle that: when the stator moves to a position coaxial with the movable shaft 304 under the drive of the movable feeding device 200; firstly, the telescopic driving mechanism 305 drives the movable shaft 304 to move, so that a fixed ring 309 arranged on the movable shaft 304 is far away from the hollow shaft 303, and at the moment, the clamping block 306 is close to the hollow shaft 303 under the driving of the movable connecting rod 308, so that the circumference radius formed by the clamping block 306 is reduced; secondly, the clamping driving mechanism 302 drives the clamping bracket 301 to move leftwards, so that the clamping block 306 stretches into the hollow structure of the stator; thirdly, the telescopic driving mechanism 305 drives the movable shaft 304 to move, so that a fixed ring 309 arranged on the movable shaft 304 is close to the hollow shaft 303, and at the moment, the clamping block 306 is far away from the hollow shaft 303 under the driving of the movable connecting rod 308, so that the circumference radius formed by the clamping block 306 is enlarged until the clamping block 306 contacts with the inner side wall of the stator, and the stator is clamped from the inner side; finally, the telescopic driving mechanism 305 drives the movable shaft 304 to reversely move, so that the clamped stator moves to the right below the paint dripping device 400, so that paint dripping operation is facilitated, in the paint dripping process, the rotary driving mechanism drives the hollow shaft 303 to rotate, the stator clamped and fixed by the clamping block 306 synchronously rotates under the driving of the supporting connecting rod 307, so that uniform paint dripping operation is facilitated, and in addition, due to the arrangement of the connecting sleeve between the movable shaft 304 and the telescopic driving mechanism 305, even if the movable shaft 304 rotates under the driving of the movable connecting rod 308, the torque of the movable shaft 304 cannot influence the telescopic driving mechanism 305.
