Description

Bolt-lock hole drilling jig

Technical field

This utility model relates to the boring grab in machining, specifically bolt-lock hole drilling jig.

Background technology

It is known that bolt is a kind of the most frequently used part in the industrial production, volume of production is the biggest.Bolt is the most all Insurance to be beaten, so must there be insurance hole its end, so-called insurance hole is the radial hole (as shown in Figure 1) by bolt axis, Owing to screw cross-section is circular, bad during boring determining bore position accurately, clamping is bad, causes holing crooked, reaches not To using requirement, it is therefore desirable to there is a kind of effective boring grab.

Summary of the invention

This utility model provides a kind of bolt-lock hole drilling jig, by location guiding mechanism, it is possible to ensure that bolt is protected The accurate location of danger hole drilling, and easy to use.

The technical solution of the utility model is as follows: bolt-lock hole drilling jig includes base plate, and its component part also includes Drill jig bearing, spacing bearing, limited block, compressing support, V-arrangement locating piece and drill bushing, part based on base plate, it installs drill jig and props up Seat, V-arrangement locating piece and spacing bearing, drill jig bearing bottom is installed drill bushing equipped with hold-down bolt, top, is filled above V-arrangement locating piece Having compressing support, compressing support upper end is connected with V-arrangement locating piece with hold-down bolt, compressing support bottom curved handle latch, limit Position bearing is provided with limited block, and limited block is connected with hold-down bolt, and spacing bearing bottom is with hold-down bolt, and drill jig bearing can left and right Regulation, compressing support can upper and lower regulate, and limited block also can upper and lower regulate, and workpiece bolt is placed in during work the V of V-arrangement locating piece Shape groove, is fixed by four hold-down bolts after regulating by bolt specification and the requirement of position, hole, implements drilling.

This utility model has following beneficial effect: 1, due to keeper, locating part, the common effect of compressing member, can protect The accuracy of card bore position and drilling quality；2, easy to use and flexible, efficiency is high, can be suitable for the brill in all size insurance hole System and production in enormous quantities.
