Block 8 and attachment screw 21 move forward under the effect of spring 22 to be resetted, and the head of attachment screw 21 can be limited by clamping bar 20, so as to
Limit the extreme position that sliding block 8 moves forward.
Before drilling, the pedestal 1 of this drilling tool is located on the workbench of high-precision drilling machine.Clamping shake beam Z when, first
20 left end of clamping bar is pulled, 20 right end of clamping bar is made to do micro swing backward around pivot screw 18, so as to drive attachment screw 21
And sliding block 8 moves backward together, to reserve clamping position, and the beam Z that shakes is placed on 1 top surface of pedestal of 8 front side of sliding block；Make to shake
6 point contact of positioning ball of the right end of beam Z and the second micrometer component, the front side for the beam Z that shakes and the positioning of the first micrometer component
6 point contact of steel ball can adjust the right position and front and back position for the beam Z that shakes by the micrometer for controlling two micrometer components, most
The left end for pulling clamping bar 20 is decontroled afterwards, the rear side for the beam Z that shakes is compressed by sliding block 8, is bored so as to the drill bit of drilling machine in the beam Z right parts that shake
Hole；After being drilled a hole, the beam Z that shakes is removed rear and the left and right for the beam Z that shakes is commutated.During commutation drilling, motionless two micrometer groups
The micrometer of part, the reading of amesdial 15 also should be identical with before commutation drills, ability accurate positioning in this way, finally in the beam that shakes
The left part drilling of Z, so as to drill in the left and right portion for the beam Z that shakes, can thus be effectively ensured the symmetrical of upper two holes of the beam Z that shakes
Degree.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not limitation with the present invention, all in essence of the invention
All any modification, equivalent and improvement made within refreshing and principle etc., should all be included in the protection scope of the present invention.
