Detailed Description
As shown in fig. 1 and 2, the auxiliary positioning device for the spindle of the numerically controlled lathe comprises an adjusting clamp, a mounting part, a positioning shaft 1 and a long cylinder 4 which are all of hollow structures. The positioning shaft 1 is coaxially arranged in the long cylinder 4, and the length of the positioning shaft 1 is greater than that of the long cylinder 4. One end of the long cylinder 4 is provided with a flange device for synchronously fixing the long cylinder 4 and the positioning shaft 1, and the end part of the other end of the long cylinder 4 is sequentially provided with the mounting part and the adjusting clamp. One end of the adjusting clamp is clamped on the long cylinder 4, and the other end of the adjusting clamp is clamped on the positioning shaft 1. In this embodiment, the mounting member includes a gasket 5 and a lock nut 6 that can be freely screwed onto the long cylinder 4, and a thread that is used in cooperation with the lock nut 6 is provided on an outer wall body of the long cylinder 4.
