But a kind of drilling jig for oil charging hole that the U of CN 202752664 are announced, there is following deficiency：1st, wheel is to pass through screw rod
And nut anastomosis is fixedly connected between chassis and drill jig, in car wheel oil filling hole process, the drill bit of radial drilling machine
Through drill jig hole, the fixing nut easily caused due to vibrations on drill jig is loosened, and causes drill jig to loosen and position and angle occurs
Degree skew, so as to cause bit damage, reduce processing efficiency；2nd, drill jig loosens position occurred and angle skew and can accelerate to bore
The abrasion of nib and influence machining accuracy, now need to change whole drill jig, and drill jig high processing costs, so as to add enterprise
Processing cost.
Utility model content
The utility model a kind of car wheel oil filling hole drill jig, can be avoided in car to overcome problems of the prior art
During alternate water injection machining of oil hole, the generation of position and angle shift phenomenon occurs because drill jig caused by vibrations loosens, so as to
The probability of bit damage is greatly reduced, improves drilling efficiency.
The utility model adopts the following technical scheme that to solve above-mentioned problems of the prior art.
A kind of car wheel oil filling hole drill jig, including bushing plate, the bushing plate includes drill jig straight panel and drill jig swash plate, drill jig are straight
The centre of plate is provided with drill jig through holes, and drill jig hole is provided with drill jig swash plate, it is characterised in that：Also include elastic ring and drill bushing,
The elastic ring is fixedly installed on the bottom of the drill jig straight panel, and the elastic ring is coaxially set with drill jig through holes, the bullet
Property circle outer wall and the swelling of vehicle wheel hub bore inwall coordinate, the drill bushing is fixed by socket in the drill jig hole.
Further, the elastic ring is nylon elastic circle.
Further, the elastic ring is fixedly connected on the bottom of the drill jig straight panel using bolt.
Further, fixing screws are provided with the drill bushing, the drill bushing is fixedly connected on drill jig by fixing screws
On swash plate.
Relative to prior art, the utility model achieves following beneficial effect：
1st, a kind of car wheel oil filling hole drill jig provided by the utility model, the bottom fixed setting of the bushing plate are flexible
Circle, outer wall and the swelling of vehicle wheel hub bore inwall of elastic ring coordinate, and in car wheel oil filling hole process, both vibrations is caused very much
Fixing nut on drill jig loosens, but because the elastic reaction of elastic ring, which makes it be produced between vehicle wheel hub bore, is relatively fixed work
With so that the bushing plate being fixed on elastic ring is remained secured at operating position, so as to greatly reduce the general of bit damage
Rate, improve drilling efficiency.
2nd, a kind of car wheel oil filling hole drill jig provided by the utility model, the drill bushing are actively coupled fixation using detachable
In the drill jig hole, drill bushing only can be worn in car wheel oil filling hole process, without causing to wear to bushing plate, works as brill
When set abrasion needs to change, need to only unclamp fixed screw can pull down impaired drill bushing, without changing whole bushing plate,
Reduce the processing cost of enterprise.
Brief description of the drawings
, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The accompanying drawing to be used is briefly described, it should be apparent that, drawings in the following description are only some realities of the present utility model
Example is applied, for those of ordinary skill in the art, on the premise of not paying creative work, can also be according to these accompanying drawings
