Description

High-precision drilling hole tool

Technical field

The utility model relates to technical field of tooling clamps, relates in particular to the positioning fixture for workpiece is holed.

Background technology

Workpiece 1 as shown in Figure 1, it is rectangular configuration, center is with rectangular channel 12, now need its end face to get out locating hole 11, use common positioning instant to complete, but because the required precision of boring is higher, must use special-purpose frock to position it, and frock must be easy to use, clamping efficiency is high, can guarantee its machining accuracy again simultaneously.

Utility model content

The utility model, for above-mentioned shortcoming of the prior art, provides a kind of high-precision drilling hole tool, and it is simple in structure, flexible and convenient to use, and clamping efficiency is high, and machining accuracy is high.

The technical scheme that the utility model adopts is as follows:

High-precision drilling hole tool, comprises base and location-plate, and on base, with supporting seat, supporting seat is vertically with dovetail groove, and supporting seat sidewall is provided with screw, and screw end stretches in dovetail groove; Location-plate sidewall is with forked tail platform, and on location-plate, with positioning table and drill jig, forked tail platform is positioned at the dovetail groove of supporting seat.

The utility model has the advantage of: according to the structure of workpiece, the location-plate of the positioning table that band is identical with workpiece centre groove structure is set, simultaneously on location-plate with forked tail platform in the dovetail groove of supporting seat, height that can up-down adjustment location-plate, during workpiece pressing, carries out Drilling operation by the drill jig on location-plate to workpiece downwards, simple in structure, flexible and convenient to use, clamping efficiency is high, and machining accuracy is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of workpiece.

Fig. 2 and Fig. 3 are structural representation of the present utility model.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.

As shown in Figure 1 to Figure 3, the utility model comprises base 2 and location-plate 6, and on base 2, with supporting seat 3, supporting seat 3 is vertically with dovetail groove 4, and supporting seat 3 sidewalls are provided with screw 5, and screw 5 ends are stretched in dovetail groove 4; Location-plate 6 sidewalls are with forked tail platform 7, on location-plate 6 with positioning table 9 and drill jig 8, forked tail platform 7 is positioned at the dovetail groove 4 of supporting seat 3, when workpiece 1 is positioned, positioning table 9 coordinates with the rectangular channel 12 on workpiece 1, and location-plate 6 is pressed on the end face of workpiece 1, and unscrewing or screw screw 5 can be along the height of dovetail groove 4 up-down adjustment location-plates 6, when location-plate 6 is pressed in the end face of workpiece 1, by 8 pairs of workpiece of drill jig, carry out Drilling operation;

Using method of the present utility model is as follows:

The first step, is placed in workpiece 1 on base 2;

Second step, the height along dovetail groove 4 adjusting location-plates 6, stretches in the rectangular channel 12 on workpiece 1 positioning table 9;

The 3rd step, screws 5 pairs of forked tail platforms of screw 7 and clamps, and guarantees that location-plate 6 is pressed on the end face of workpiece 1;

The 4th step processes locating hole 11 on workpiece 1 by drill jig 8.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
