Further, the method comprises the following steps:

as shown in fig. 1-6:

with the above in mind: the positioning assembly 2 comprises a push block 22, a push piece 23, a sliding rod 24, a punch 25, a fixing block 26 and an expansion strip 27, wherein the push piece 23 is arranged on one side, away from the needle 1, of the push block 22, one side, away from the push block 22, of the push piece 23 is fixedly connected with one end of the sliding rod 24, the other end of the sliding rod 24 is fixedly connected with the surface of one side, close to the needle 1, of the punch 25, the surface of the sliding rod 24 is connected with the surface of the fixing block 26 in a sliding mode, one side, away from the needle 1, of the fixing block 26 is connected with one end of the expansion strip 27 in a sliding mode, and the expansion strip 27 is attached to the punch 25.

In this embodiment: when the thimble needs to be positioned in the middle of a lathe, the punch cone 25, the fixed block 26 and the expansion strip 27 can be placed in a mounting hole on the lathe together, then the push block 22 arranged on the rack 21 is pushed, the push block 22 pushes the push sheet 23 to move, then the slide rod 24 integrated with the push sheet 23 slides along a groove formed in the fixed block 26, the punch cone 25 is driven to move, the expansion strip 27 is extruded to rotate with the fixed block 26, the expansion strip 27 is opened, and the expansion strip is tightly attached to the inner wall of the mounting hole, so that the positioning work of the thimble is completed.
