Abstract
The utility model discloses an elastic tapping chuck, and relates to a tapping chuck. The elastic tapping chuck aims at solving the problems that when a rigid tapping chuck is adopted, the vibration is great, the service life of a tool is short, the probability of disorderly buckling when a threaded hole is processed is high, and the processing quality of the threaded hole is affected. A plurality of ball mounting grooves are uniformly and circumferentially distributed and processed in an external wall of a large end of a tail handle; a ball ferrule is mounted on the external wall of the tail handle in a sleeving manner; balls are positioned in the ball ferrule; a first baffle penetrates through the large end of the tail handle to be fixedly connected with the ball ferrule; one end of a connecting body penetrates through the large end of the tail handle to be in threaded connection with the ball ferrule; the ball ferrule and the connecting body are radially located by two clamping screws; a compression spring is positioned at the root of a center blind hole; one end of the compression spring is contacted with a shoulder of a jackscrew; a second baffle penetrates through the other end of the jackscrew to be fixedly connected with the large end of the tail handle; a tap chuck is fixedly mounted at the other end of the connecting body; and the other end of the jackscrew is contacted with the end face of the tap chuck. The elastic tapping chuck is used for processing a connecting threaded hole of an air cylinder.
