Drilling-hole positioning device
The utility model relates to a kind of drilling-hole positioning device.
At present, the boring of workpiece is generally adopted to highwall-drilling machine, when highwall-drilling machine is holed to workpiece, need to be by workpiece stationary positioned.Traditional mode that workpiece is fixed to location is to adopt two horizontal screw rods to draw close the both sides of clamping workpiece, thereby workpiece is fixed on workbench, and then the drill bit on highwall-drilling machine is descending holes on workpiece.But during this boring, the locate mode of workpiece is extremely bothered, reduced operating efficiency, and owing to being manual drive screw rod and clamping work pieces, so the precision of its location is also not high enough.
Summary of the invention
For the deficiencies in the prior art, problem to be solved in the utility model is to provide a kind of drilling-hole positioning device that workpiece positions and precision is higher to needs boring quickly.
For this reason, the utility model is realized in the following way: a kind of drilling-hole positioning device, it is characterized in that: comprise upper bolster and die shoe, described upper bolster is connected by column with die shoe, the lower surface of described upper bolster is provided with locating piece, described locating piece is provided with nib, and described die shoe is provided with the cylinder axis of cylinder and cylinder towards nib, and described upper bolster is provided with the boring corresponding with nib.
Described upper bolster is provided with chute, in described chute, is provided with slide block, and described slide block lower surface is provided with the alignment pin corresponding with nib, and described boring is located on slide block.
In the utility model, workpiece is placed in the nib on upper bolster, driving cylinder top to workpiece, workpiece to be held out against is fixed in nib, just can realize fast the location to drilling-workpiece, then rig just can be holed by the boring on upper bolster on workpiece, and visible this device is very quick to the location of drilling-workpiece, greatly improved operating efficiency, and because workpiece is fixed by the nib mating with it, therefore the precision of location is also more increased, thereby improved the precision of boring.

The specific embodiment
With reference to bowing, this drilling-hole positioning device, comprise upper bolster 1 and die shoe 6, described upper bolster 1 is connected by column 5 with die shoe 6, the lower surface of described upper bolster 1 is provided with locating piece 9, described locating piece 9 is provided with nib 10, described die shoe 6 is provided with the cylinder axis of cylinder 4 and cylinder 4 towards nib 10, described upper bolster 1 is provided with the boring corresponding with nib 10 3, described upper bolster 1 is provided with chute 7, in described chute 7, be provided with slide block 2, described slide block 2 lower surfaces are provided with the alignment pin corresponding with nib 10 8, and described boring 10 is located on slide block 2.When workpiece being holed to location, first slide block 2 is outwards exited to a segment distance, workpiece can be placed in nib 10, then inwardly promoting slide block 2 makes the alignment pin 8 on slide block 2 coordinate workpiece is located with nib 10, then on cylinder 4, top presses closer workpiece to be fixed in nib 10, so just realized the location to workpiece, rig can carry out drilling operation by 3 pairs of workpiece of the boring on slide block 2.
