Abstract

The invention relates to a double-face drilling jig which comprises a jig body, a cover plate, supporting feet, a positioning post, a V-shaped block and guide sleeves, wherein the cover plate is arranged on the jig body; the supporting feet are arranged on the lower surface of the jig body and the upper surface of the cover plate and fixedly connected with the jig body and the cover plate; the positioning post is arranged on the upper surface of the jig body, fixedly connected with the jig body and provided with nuts used for pressing a workpiece; the V-shaped block is arranged on the upper surface of the jig body and fixedly connected with the jig body; and the guide sleeves are arranged on the jig body and cover plate and fixedly connected. After a workpiece is fixed by the jig, three surfaces of the workpiece can be punched without secondary mounting, thereby solving the problem of reduced repeated positioning precision caused by twice mounting so as to easily process the workpiece.

Description

Double-face drilling jig

Technical field

The present invention relates to a kind of double-face drilling jig that is applied in the boring processing.

Background technology

When two faces of workpiece all have boring requirement, need usually to install to realize for twice in the prior art.So not only production efficiency is not high, and repeats to have brought into the installation accuracy error in twice installation, has reduced the machining accuracy of workpiece.

Summary of the invention

The purpose of this invention is to provide a kind of anchor clamps that can double-face drilling, can realize double-face drilling processing.

The technical solution adopted in the present invention is: a kind of double-face drilling jig, comprise clamp body, be positioned at the cover plate on the described clamp body, the feet that is positioned at described clamp body lower surface and cover plate upper surface and fixedlys connected with cover plate with described clamp body, be positioned at the upper surface of described clamp body and the reference column of fixedlying connected with clamp body, there is nut to be used for workpiece pressing on the described reference column, be positioned at the upper surface of described clamp body and the vee-block of fixedlying connected, and be positioned at the guide pin bushing of fixedlying connected on described clamp body and the described cover plate with clamp body.

Owing to adopted above technical scheme to make the present invention have following advantage: after these anchor clamps are fixed workpiece, just can be without secondary installing in three face punchings of workpiece, the problem of having avoided twice installation to cause repetitive positioning accuracy to reduce can easily realize the processing of workpiece.

Accompanying drawing 2 is main body figure of the present invention;

Accompanying drawing 3 is the body figure that bows of the present invention;

Accompanying drawing 4 is a upward view of the present invention;

Wherein: 1, clamp body; 2, cover plate; 3, reference column; 4, nut; 5, guide pin bushing; 6, vee-block; 7, feet; 8, workpiece; 9, first to be processed; 10, second to be processed; 11, the 3rd to be processed.

The specific embodiment

Referring to accompanying drawing 2 to shown in the accompanying drawing 4, a kind of double-face drilling jig, comprise clamp body 1, be positioned at the cover plate 2 on the described clamp body 1, the feet 7 that is positioned at described clamp body 1 lower surface and cover plate 2 upper surfaces and fixedlys connected with cover plate 2 with described clamp body 1, be positioned at the upper surface of described clamp body 1 and the reference column 3 of fixedlying connected with clamp body 1, be useful on the nut 4 of workpiece pressing 8 on the described reference column 3, the upper surface of described clamp body 1 is provided with the vee-block 6 of fixedlying connected with clamp body 1, offer a plurality of holes on described clamp body 1 and the described cover plate 2, fixedly be equipped with the guide pin bushing 5 that can supply drill bit to stretch in the described hole.

Cover plate 2 removably is connected on the clamp body 1, and formal first being processed is at first taken off cover plate 2, and a side that workpiece 8 is processed installing hole is through on the reference column 3, tightens fixing with nut 4.Like this three coordinate directions of the common restriction of reference column 3 nuts 4 workpiece move and around the rotation of two coordinate directions, the latter half of workpiece 8 is placed on the vee-block 6, vee-block 6 restriction workpiece 8 are around the rotation of a remaining coordinate direction, to realize six point locations of workpiece 8, at last cover plate 2 is reinstalled on the clamp body 1 and just can have formally processed, drill bit stretches in the guide pin bushing 5 of anchor clamps upside, to first to be processed 9 boring, after processing for first to be processed 9 with anchor clamps upsets, second to be processed 10 and the 3rd to be processed 11 of reprocessing workpiece 8.

Described clamp structure is simple, can easily realize the two-sided processing of workpiece, and can improve machining accuracy.
