Description
Technical field
The present invention relates to a kind of detachable drill jig and its methods for drilling composite material location hole, belong to a kind of backman
Dress.
Background technology
In composite material parts manufacturing process part is manufactured by the way of pre-buried Teflon pin before curing mostly
Milling location hole, but due to composite material, volume can expand after hardening, and position of positioning hole, which has, after curing generates certain deviation
Influence milling precision.
Invention content
The technical problem to be solved in the present invention is to provide a kind of detachable drill jig and its drill the side of composite material location hole
Method, the detachable drill jig utilize the hole of fixing tool and the support arm of fixed range, make the position of positioning hole after curing constant, so as to
It ensure that the element precision after curing.
To solve problem above, the specific technical solution of the present invention is as follows：A kind of detachable drill jig, sets at the center of pedestal
There is threaded hole, the both sides of threaded hole are arranged with location hole, and support arm is set in the upper surface of pedestal, and one end of support arm, which is equipped with, bores
Set, the other end are equipped with fixed knob, and the bottom of fixed knob and the screwed hole of centre of pedestal are connected, set in the both sides of fixed knob
There is positioning pin, positioning pin is inserted into the location hole of pedestal.
The method that composite material location hole is drilled using detachable drill jig, is included the following steps：
1）The groove consistent with base bottom surface shape is set in the tooling for treating laying prepreg, and groove is with treating laying prepreg
Without interference；
2）It has marked the composite material after lay-up molding that need to drill the position in hole in tooling, and has been carried out with the central axis of pedestal
Line forms mark line；
3）The distance L of centre distance base central in hole need to be drilled, and process support arm by calculating the composite material after lay-up molding
Length, the center and tightening knob centre distance for making the drill bushing on support arm are equal to L；
4）Location hole on pedestal is set, ensures the line of centres and step 2 of two location holes）Label line overlap；
5）By prepreg laying in the tooling prepared, the fixed pedestal in groove；
6）The good prepreg of laying is placed together with tooling in furnace body and carries out hot setting；
7）Part is taken out, and carry out natural cooling together with tooling after curing；
8）Support arm on pedestal is installed, and passes through tightening knob and positioning pin is fixed on pedestal, is installed in the opposite side of support arm
Drill bushing is directly drilled by drill bushing, you can obtains the hole of distance to a declared goal；
9）Composite material after curing is removed from tooling.
The detachable drill jig uses the structure of regular length support arm, avoids prefabricated hole composite material in cured process
It is middle to lead to the problem of expansion and generate error, it is directly drilled on the composite material being cured by the drill bushing on support arm,
So as to ensure that the dimensional accuracy of part.
Using the method that detachable drill jig drills composite material location hole using above-mentioned steps, it ensure that drill bushing no matter in length
It is limited on degree and in angle, ensure that the precision of drill bushing position, that is, ensure that the precision for drilling hole, be convenient for
The batch production of composite material improves processing efficiency.
