Embodiment 1
[0035] Embodiment one: see attached figure 1 to attach Figure 4 shown. A main shaft self-locking mechanism, which is connected with the main shaft 23 to realize the self-locking function for the main shaft 23 .
[0036] The spindle self-locking mechanism includes a planet carrier 1 , a fixed plate 2 , an adapter plate 3 , and a compression spring 4 .
[0037] The adapter plate 3 and the main shaft 23 are fixedly connected by splines and rotate coaxially. A gasket 5 is provided between the adapter plate 3 and the compression spring 4 , and the main shaft 23 is provided with a bearing 6 and a static end tooth 7 . It is defined that the main shaft 23, the static end teeth 7, and the bearing 6 together form the collet 8.
[0038] The planetary carrier 1 is coaxially connected with the adapter disc 3 . At least one pair of first bosses 9 are provided on the end surface of the planet carrier 1 near the adapter plate 3 . A pair of first bosses 9 are symmetrically arranged along...
