Abstract
The utility model belongs to part drilling technology, relates to a drilling die for drilling small hole pitches, and particularly relates to a drill bushing rotation type drilling die, which comprises a drill bushing, a drilling die plate and positioning pins. The drill bushing consists of an end and a guiding head which are connected with each other, wherein the diameter of the end is larger than that of the guiding head, guiding holes which are mutually coaxially communicated are arranged in the middles of the end and the guiding head, the guiding head of the drill bushing is inserted in a mounting hole in the drilling die plate, two positioning clamp grooves are symmetrically arranged on the end of the drill bushing, a connecting line between the two positioning clamp grooves passes through an axle center of the drill bushing, the distance between connection lines from the center of the guiding hole to the two positioning clamp grooves is 1/2 of the hole pitch of holes to be drilled, and the positioning pins are fixedly arranged on the drilling die plate and inserted in the positioning clamp grooves. The drill bushing rotation type drilling die can drill multiple groups of holes or kidney-shaped holes with small hole pitches on the drilling die plate, is simple in structure and convenient in operation, effectively increases drilling efficiency, and has certain actual application value.
Description
Technical field
The utility model belongs to the part drilling technique, relates to a kind of boring mould that is used to bore the aperture distance.
Background technology
In airplane parts is made, comprise that aluminium alloy, ferrous metal close composite material parts, very little hole of one or more groups pitch-row or mounting hole are arranged on the part.Because pitch-row is too little, the drill bushing aperture is bigger, when inlaying drill bushing simultaneously on bushing plate, interferes easily.Can only do a plurality of bushing plates for this reason and hole step by step, yet make the drill jig complexity like this, production efficiency is lower.
Summary of the invention
The purpose of this utility model is: the drill bushing rotary drilling mould that provide simple in structure, easy to operate, drilling efficiency is high.
The technical solution of the utility model is: a kind of drill bushing rotary drilling mould, it comprises drill bushing, bushing plate and alignment pin, described drill bushing is made up of interconnective termination and target seeker, wherein, the diameter of termination is greater than the target seeker diameter, and be provided with the guide hole of mutual coaxial communication in the middle of the two, the target seeker of described drill bushing is inserted in the interior installing hole of bushing plate, be symmetrically arranged with two locating grooves on the described drill bushing termination, wherein, the line between two locating grooves is by the axle center of drill bushing, and the distance between the line of described guide hole center and two locating grooves is to wait 1/2 of the pitch-row of holing, described alignment pin is fixedly installed on the bushing plate, is inserted in the locating groove.
Between the locating groove of described alignment pin and drill bushing for being slidingly matched.
Between described target seeker and the bushing plate installing hole for being slidingly matched.
The utility model has the advantages that: the utility model drill bushing rotary drilling mould can get out very little hole or the mounting hole of many group pitch-rows on a bushing plate by the rotation drill bushing, solution can't be inlayed drill bushing boring problem simultaneously on a bushing plate because of pitch-row is too little, and it is simple in structure, easy to operate, effectively improve drilling efficiency, had certain actual application value.

The specific embodiment
Below the utility model is described in further details.
Referring to Fig. 1, it is the structural representation of the utility model drill bushing rotary drilling mould.Described drill bushing rotary drilling mould comprises drill bushing 1, bushing plate 2 and alignment pin 3.
Please consult Fig. 2 simultaneously, it is the structural representation of described drill bushing 1.Described drill bushing 1 is made up of interconnective termination and target seeker, and wherein, the diameter of termination is greater than the target seeker diameter, and the two middle guide hole 4 that is provided with mutual coaxial communication.And be symmetrically arranged with two locating grooves 5 on the drill bushing termination, wherein, the line between two locating grooves 5 is by the axle center of drill bushing 1.Described guide hole 4 is a circular hole, and the distance between the line of its center and two locating grooves is to wait 1/2 of the pitch-row of holing.
See also Fig. 3, it is the A-A cutaway view of Fig. 1.Described alignment pin 3 is fixedly installed on the bushing plate 2, is inserted in the locating groove 5, is used for the engaging location of locating groove 5, between the locating groove 5 of itself and drill bushing 1 for being slidingly matched.
See also Fig. 4, it is the B-B cutaway view of Fig. 1.The target seeker of described drill bushing 1 is inserted in the installing hole in the bushing plate 2, between the two for being slidingly matched.
When the utility model drill bushing rotary drilling die worker does, drill bushing 1 is by the installing hole on the bushing plate 2 and be fixed on alignment pin 3 location on the bushing plate 2, what a after boring hole drill bushing 1 is extracted, Rotate 180 °, be reapposed over again on the bushing plate 2, fixing by locating groove 5, can bore second hole with that.And drill bushing 1 can be moved on to the another one installing hole, just can get out the hole of other same specification in position.In addition,, remove intermediate sector again, can conveniently get out mounting hole by boring semicircle orifice at twice.
The utility model drill bushing rotary drilling mould can get out very little hole or the mounting hole of many group pitch-rows by the rotation drill bushing on a bushing plate, solution can't be inlayed drill bushing boring problem simultaneously on a bushing plate because of pitch-row is too little, and simple in structure, easy to operate, effectively improved drilling efficiency.
