Description

A kind of double-face drilling jig
Technical field
The present invention relates to a kind of anchor clamps, 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.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of double-face drilling jig, it can fast, accurately process the workpiece of two sides boring.
Technical solution of the present invention is achieved in that 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 present invention compared with prior art has advantage:
Double-face drilling jig of the present invention, 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.

Accompanying drawing l is the perspective view of workpiece to be processed;
Accompanying drawing 2 is the stereogram of double-face drilling jig of the present invention;
Accompanying drawing 3 is the front view of accompanying drawing 2;
Accompanying drawing 4 is the three-dimensional exploded view of double-face drilling jig of the present invention;
Wherein: 1, workpiece; 2, blind hole; 3, base plate; 4, locating rack; 5, swivel mount; 6, rotating shaft; 7, fixed block; 8, chute; 9, screw rod; 10, thread bush; 11, locating piece; 12, column; 13, swiveling wheel; 14, handle.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Accompanying drawing 2-3 is a kind of double-face drilling jig of the present invention, comprises the swivel mount 5 of the base plate 3, column 12, locating rack 4, screw rod 9 and the fixation workpiece 1 that are fixed on the workbench; Said column 12 is two, and is separately fixed at the both sides of base plate 3 tops; Said swivel mount 5 and can be around the rotation of the line of two columns 12 between two columns 12; The centre of said two columns 12, the below that is arranged in swivel mount 5 also is provided with screw rod 9; Said screw rod 9 is vertically fixed on the base plate 3, and screw rod 9 bottoms are fixed with swiveling wheel 13; On said two columns 12 side in opposite directions, all have chute 8; Said locating rack 4 is between two columns 12, and locating rack 4 can slide up and down in chute 8; Said locating rack 4 is positioned on the screw rod 9, and realizes the up-down of locating rack 4 through the rotation of screw rod 9; Also be provided with locating piece 11 in the heart in said locating rack 4 tops; Said locating piece 11 is arranged in the below of workpiece 1; Said swivel mount 5 comprises rotating shaft 6, fixed block 7 and handle 14; Said rotating shaft 6 is two, and is located at coaxially respectively on two columns 12; Said rotating shaft 6 is all perpendicular to column 12, and on the rotating shaft 6 on the side near screw rod 9, is equipped with fixed block 7; Said fixed block 7 is according to the shape setting of workpiece 1, and fixation workpiece 1; On the rotating shaft 6 on said right side, also be fixed with rotating handles 14 away from a side of column 12; The bottom of said locating rack 4 is fixed with a thread bush 10, and its thread bush 10 matches with screw rod 9.
