Embodiment
All features disclosed in this specification, or disclosed all methods or during the step of, except mutually exclusive
Feature and/or step beyond, can combine in any way.
As shown in figure 1, the utility model is the improvement made in existing lathe machine head.This programme changes traditional machine
Tool manual locking, steel ball is oppressed so as to realize locking function using the principle of air pressure, concrete structure is as follows.
Include a rotary shaft first, the rotary shaft passes through motor, rotated by motor driven rotary shaft, along rotary shaft
Axis be provided with air flue in rotary shaft, air flue one end of rotary shaft is connected by rotary connecting joint with the air supply pipe of cylinder,
So as to provide stable air pressure into the air flue of rotary shaft.Blind end is used in the other end of rotary shaft, for being fixedly connected with folder
Hold mechanism.
The clamping device is cylindrical shape, and the cavity structure in cylinder is grasping part, is provided with the wall of the cylinder
