When designing boring grab, need to solve there are two difficult point:
1. the number that drills in tooth socket is more, hole is close in circumferencial direction arrangement, and Kong Yukong spatial joint clearance is small, and process straight hole and
When inclined hole, the inclination angle of workbench is different, therefore when designing to tooth gauge, it to prevent between drill bit and fixture, fixture and workbench bottom surface
It interferes；
2. product figure requires drilling that cannot injure external splines starting circle, hole is symmetrical as far as possible in tooth socket, according to simulation drawing
It has been shown that, to meet above-mentioned requirements bore position degree must assure that within φ 0.2, and it is stable high-precision fixed that this needs fixture to have
Bit function.
According to traditional design scheme, if design using ringfeder+positioned to tooth gauge, if first tensioner ringfeder when processing,
Positioning requirements then will be unable to satisfy without being put into external splines tooth socket to tooth gauge；And if will first be put into tooth socket and rise again to tooth gauge
Tight ringfeder need to be designed to the automatic adjusument for having the function of to change with tooth slot position to tooth gauge, this will lead to multiple to tooth gauge structure
Miscellaneous, occupied space is big, easily causes interference.
Either optical center axis+to tooth gauge centering structure, and optical center axis positioning inner hole+to the shortcomings that tooth gauge structure be due to
Inner hole and mandrel are there are gap, and it is poor that fixture repeats accurate positionin precision, and due to there is bias between inner hole and external splines,
This part deviation also will affect the position degree of drilling, asymmetric in tooth socket so as to cause hole.
External current manufacturing process is it is currently understood that there is electrical discharge machining either water to cut, this is required, and purchase is new to be set
It is standby, cause processing cost to increase in this way.
In order to meet requirements above, it is necessary to design a kind of new construction boring grab, make both to have can guarantee that fixture had when drilling
There is higher repetitive positioning accuracy and the boring grab of interference can be prevented.
