Upper end mutually support, and it be a plane that locating piece 5, which is used to prop up the part of end face, so that locating piece and this handle of a knife section
Between breasting it is more stable, further increase locating effect of the locating piece 5 to tool rest 1.The one of locating piece 5 and tool rest 1 into
Type, without extra installation step, so also make between locating piece 5 and tool rest 1 that connection status is more stable, locating effect is more
Remarkably.
Second embodiment of the present utility model is related to a kind of full-automatic extension type precision boring cutter.Second embodiment with
First embodiment is roughly the same, is in place of the main distinction：In the first embodiment, drive device is a kind of motor and silk
The combining structure of bar, and in opening up the passage that is extended into or out for screw mandrel in the first handle of a knife section, for realizing the flexible of handle of a knife.
And in the utility model second embodiment, as shown in figure 5, drive device includes：Cylinder 16, driving top plate 17 and drive shaft
18.Wherein, cylinder 16 is arranged on the top of fixed mount 4.Driving top plate 17 be located in the cavity of the second handle of a knife section 3, and with the first knife
Handle section 2 is fixedly connected.Drive shaft 18 is connected with cylinder 16 and driving top plate 17 respectively, for driving driving top plate 17 in cavity
Moved toward and away from the direction of fixed mount 4.
Specifically, into cylinder 16, gas transmission is vented with regard to that can make drive shaft 18 along its axis toward and away from fixed mount 4
Direction moved, and drive shaft 18 involve driving top plate 17 the first handle of a knife section 2 is stretched in the second handle of a knife section 3,
Play a part of changing shank length.Thus, the boring cutter can also bore the widely different hole of hole depth, can be largely
Avoid changing boring cutter during processing, greatly lift processing efficiency.
It is noted that being connected between the driving handle of a knife section 2 of top plate 17 and first by bolt and nut, attachment structure is simple
It is practical.Certainly can also be integrally formed with the first handle of a knife section 2 according to the application demand of reality, driving top plate 17, thus can be with
Save some assembling links.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific implementation of the present utility model
Example, and in actual applications, can to it, various changes can be made in the form and details, without departing from spirit of the present utility model
And scope.
