To realize the above-mentioned technical purpose, the technical solution adopted by the present invention is as follows：
It can position, rotatable dedicated fixture for drilling, including desktop, clamp assemblies and positioning component,
The desktop offers pilot hole；
The clamp assemblies include first motor, fix ring flat-plate, lower rotating ring plate and upper rotation ring flat-plate, and described first
Motor is stepper motor, and vertically upward, the lower part outer wall of the first motor fixes peace to the power output shaft of the first motor
In pilot hole, the top exterior walls of the first motor are fixed there are three equally distributed horizontal braces, and the level is propped up
The upper surface outer end of stay is vertically and fixedly provided with strut upwards, and the upper end of the strut is detachably equipped with and horizontal braces face
Supporting block, the upper surface of the supporting block offers the matched short slot in lower part with fixed ring flat-plate, the fixed ring board
In three short slots and fixed, the outer diameter of the fixed ring flat-plate, lower rotating ring plate and upper rotation ring flat-plate is equal, the fixation
The upper surface of ring flat-plate offers annular recess, and snap ring is arranged in the annular recess, and the upper table of the snap ring is hung down upwardly
It is in directly the equally distributed loop bar of round integrally formed with more, the lower surface of the snap ring is inlaid with multiple rotatable and is in round
Equally distributed ball, the snap ring can be rotated along annular recess, and the upper surface of the lower rotating ring plate offers ring-type
Card slot, it is in the equally distributed lower rank of round that the upper surface of the lower rotating ring plate offers multiple in the corresponding position of cyclic annular card slot
Trapezoidal hole, the top heavy caliber size of the downstairs shape through-hole are more than the groove width size of cyclic annular card slot, the downstairs shape
The small-bore size in lower part of through-hole is less than the groove width size of cyclic annular card slot, and the top depth dimensions of the downstairs shape through-hole are more than
The groove depth size of cyclic annular card slot is detachably arranged with guide sleeve in the downstairs shape through-hole, and the top of the loop bar, which passes through, leads
Set, it is logical that the upper position for rotating face downstairs shape through-hole on ring flat-plate offers upper stairstepping identical with downstairs shape through-hole
Hole, opens up between the two neighboring upper stairstepping through-hole jagged, and the width dimensions of the notch are less than upper stairstepping and lead to
The top heavy caliber size in hole, the depth dimensions of the notch are less than the top depth dimensions of upper stairstepping through-hole, the upper rank
Trapezoidal hole and notch are connected composition ring-type, and the position of the lower rotating ring plate and upper rotation ring flat-plate within ring offers
Multiple is in the equally distributed mounting hole of round, and the lower rotating ring plate and upper rotation ring flat-plate are detachably equipped with spiral shell by mounting hole
Detachable card is equipped with chuck and card, the chuck and card one respectively in column, the upper stairstepping through-hole and notch
Molding constitutes cyclic annular, the upper lower surface for rotating ring flat-plate flange collar in the position integrated molding within mounting hole, the convex
The inner wall of circle and the power output shaft of first motor are fixed, and the lower end of the interior flange collar may pass through lower rotating ring plate, the upper rotation
For the lower surface edge of change plate integrally formed with outer flange collar, the height dimension of the outer flange collar is five points of interior flange collar height dimension
One of, it is in the equally distributed locating notch of round that the outer flange collar, which offers multiple, and the locating notch is placed exactly in adjacent
Between two upper stairstepping through-holes, detachable card is equipped with locating piece in the locating notch, and the outer end of the locating piece offers
Location hole；
The positioning component includes three cylinders, and the cylinder interlocks with horizontal braces and is located at the same circle
On, the bottom of the cylinder is vertical with desktop to be fixed, and the top of the top push rod of the cylinder offers U-shaped card slot, three
