A kind of double-face drilling jig

Technical field

The utility model relates to a kind of anchor clamps, and the anchor clamps that especially a kind of double-face drilling is used belong to drilling machine processing and use the fastener technical field.

Background technology

In mechanical processing industry, when utilizing drilling machine boring, all be that workpiece is placed on the workbench, and fix through pressing plate and clamp nut, carry out bore operation then.For some workpiece, the workpiece shown in the accompanying drawing 11 for example, its needs drilling blind hole, and also this workpiece need all need drilling blind hole 2 on tow sides.When boring this type workpiece, all be the hole of subdrilling one side, take off workpiece then, be turned to another side and hole again.The benchmark in two groups of holes getting out, two sides just has deviation like this, for the high workpiece of some required precisions, when assembling; These mismachining tolerances will cause dress to unmatch; The workpiece that has just needs location processing once more, and the workpiece that can not do over again that has just can only have been scrapped.So not only reduce working (machining) efficiency, increased labor intensity of operating personnel, but also wasted a lot of time and materials.

The utility model content

The utility model purpose is for the deficiency that overcomes prior art a kind of double-face drilling jig to be provided, and it can fast, accurately process the workpiece of two sides boring.

For achieving the above object, the technical scheme that the utility model adopts is: a kind of double-face drilling jig comprises the swivel mount of the underframe, locating rack, screw rod and the fixation workpiece that are fixed on the workbench; Said underframe is made up of a base plate and two columns that are fixed on the base plate top; Said swivel mount and can be around the rotation of the line of two columns between two columns; In the middle of said two columns, the below that is arranged in swivel mount also is provided with screw rod; Said screw rod is vertically fixed on the base plate, and the screw rod bottom is fixed with swiveling wheel; On said two columns side in opposite directions, all have chute; Said locating rack is between two columns, and locating rack can slide up and down in chute; Said locating rack is positioned on the screw rod, and realizes the up-down of locating rack through the rotation of screw rod; Also be provided with locating piece in the heart in the said locating rack top; Said locating piece is arranged in the below of workpiece.

Preferably, said swivel mount comprises rotating shaft and fixed block; Said rotating shaft is two, and is located at coaxially respectively on two columns; Said rotating shaft is all perpendicular to column, and on the rotating shaft near a side of screw rod, be equipped with fixed block; Said fixed block is according to the shape setting of workpiece, and fixation workpiece.

Preferably, on said one of them rotating shaft, also be fixed with rotating handles away from a side of column.

Preferably, the bottom of said locating rack is fixed with, a thread bush, and its thread bush matches with screw rod.

Because the utilization of technique scheme, the utility model compared with prior art has advantage:

A kind of double-face drilling jig of the utility model scheme, it adopts the swivel mount that can rotate to fix workpiece, and through locating rack workpiece is located; Behind pressing plate and clamp nut workpiece pressing, the front of workpiece is begun boring, after boring is accomplished; Through the handle on screw rod adjusting and the swivel mount, with the workpiece upset, the reverse side hole of reprocessing workpiece; Workpiece only needs clamping once, has not only saved a lot of times, has reduced operating personnel's working strength; And the machining benchmark of the positive and negative face of workpiece is same, improved the crudy of double-face drilling operation, improved the machining accuracy of workpiece.
