Description
Technical field
The utility model relates to a kind of positioner, and the positioner of mainly a kind of model boring, belongs to field of machining.
Background technology
Numeric Control Technology develop into the transformation that production technology brings internal, the appearance of some special process methods solves the problem of conventional machining process complexity.The production of getting off the plane of traditional mode of production pattern is mainly lofting templating process, present stage sample plate mainly in Aircraft Production play role of inspection.The application of digital control drawing and laser cutting technique substantially increases the production efficiency of sample plate, by the phenomenon that there will be circularity over tolerance when diameter is less than the circular hole of 3mm on laser cutting machine cutting model, so when on processing model, diameter is less than the circular hole of 3mm, on model, first carve the position of central point of hole with laser cutting machine, then holed with drilling machine by workman.According to the visual tool setting of scribe line position when workman holes with drilling machine, because the central point carved is very little, tool setting difficulty is comparatively large, and tool setting precision and efficiency are very low, and then have impact on machining accuracy and the efficiency of model.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of model drilling-hole positioning device, for realizing positioning function during model boring, by the centering cone on fork and fork, accurate location drilling is carried out to model, model borehole accuracy can be improved like this, improve drilling efficiency, shorten the processing and manufacturing cycle of model.
For overcoming the above problems, concrete technical scheme of the present utility model is as follows: a kind of model drilling-hole positioning device, the side of annular fixed seat is fixed with auricle, the vertical bar of L shape fork is flexibly connected with auricle, the horizon bar of fork is provided with through hole, centering cone is connected with through hole whorl, the axial line of through hole overlaps with the axial line of holder, the axial line of centering cone overlaps with the axial line of through hole, the excircle side of holder is distributed with the locating hole of more than three, set bolt is threaded with locating hole.
The lower surface of described holder is provided with boss, boss and auricle are positioned at the same side, and the side of boss is provided with spacing hole, and spacing hole opening direction and auricle are in the same way, be connected with adjustment screw in spacing hole, the other end end face of adjustment screw is vertical tangent with the vertical bar of fork.
Described locating hole is four, and locating hole is evenly distributed on the excircle side of holder.
Described centering cone is stairstepping, and minor diameter one end is connected with through hole whorl, and major diameter one end is pyramidal structure, and tap web direction is downward.
The utility model has the advantage of: the through hole axial line of the horizon bar of fork overlaps with the axial line of holder, the axial line of centering cone overlaps with the axial line of through hole, the coincidence of three's axial line ensure that the accuracy of this device in position fixing process, reduce the tool setting difficulty of workman in tool setting process, increase work efficiency.
Be fixed on drilling machine by the set bolt being evenly distributed on holder excircle side by this device, four set bolts are uniformly distributed, and ensure that this device stability in operation, ensure operating accuracy.
The spacing hole that holder lower surface boss is provided with is by being flexibly connected with adjustment screw, the other end of adjustment screw is vertical tangent with the vertical bar of fork, adjustment screw plays position-limiting action, not only prevent fork from swing process, bumping against boss, cause part to destroy, again by the restriction to fork, the axial line of centering cone be flexibly connected with the horizon bar of fork is overlapped with the axial line of holder, the central point of hole that model carves is found in guarantee accurately, improves tool setting efficiency.

Detailed description of the invention
As shown in Figure 1, a kind of model drilling-hole positioning device, the side of annular fixed seat 1 is fixed with auricle 7, the vertical bar of L shape fork 5 is flexibly connected with auricle 7, and the horizon bar of fork 5 is provided with through hole 8, and centering cone 6 is threaded with through hole 8, the axial line of through hole 8 overlaps with the axial line of holder 1, the axial line of centering cone 6 overlaps with the axial line of through hole 8, and the excircle side of holder 1 is distributed with the locating hole 9 of more than three, set bolt 4 is threaded with locating hole 9.
The lower surface of holder 1 is provided with boss 2, boss 2 and auricle 7 are positioned at the same side, and the side of boss 2 is provided with spacing hole 10, and spacing hole 10 opening direction and auricle 7 are in the same way, be connected with adjustment screw 3 in spacing hole 10, the other end end face of adjustment screw 3 is vertical tangent with the vertical bar of fork 5.Adjustment screw 3 plays position-limiting action, has both prevented fork 5 and boss 2 from colliding, can ensure that again the axial line of centering cone 6 overlaps with the axial line of holder 1, ensured the accuracy of tool setting.
As shown in Figure 2, locating hole 9 is four, and locating hole 9 is evenly distributed on the excircle side of holder 1.
As shown in Figure 1, centering cone 6 is stairstepping, and minor diameter one end is threaded with through hole 8, and major diameter one end is pyramidal structure, and tap web direction is downward.
The course of work:
First, this device is placed on drill press spindle, adjustment adjustment screw 3 and fork 5, make fork 5 vertical with adjustment screw 3 tangent, position is now that the axial line of centering cone 6 overlaps with the axial line of holder 1 just, drill press spindle moves integrally this device, and make the dead in line of the drill bit on the axial line of centering cone 6 and drilling machine, positioning work completes; Then start tool setting, rotate drilling machine rocking arm, this device is declined, movement needs the model of tool setting, and on the taper cusp of centering cone 6 is dropped on central point of hole that model carves, tool setting work completes; Finally swung laterally by fork 5, make centering cone 6 leave cutter position, continue to rotate drilling machine rocking arm and hole, the course of work terminates.
