In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
Face combines and is specifically illustrating, and the utility model is further described.
Embodiment 1, referring to Fig. 1 --- a kind of facing attachment shown in Fig. 7, it includes chamfering device 1, pressing plate 2, guiding axis 3, shield
Set 4 and sand paper 5, the chamfering device 1 are in frusto-pyramidal configurations, and the outside of chamfering device 1 is equipped with the matched sand paper 5 of shape,
The large end face of angle device 1 is removably equipped with the circular pressing plate 2 for pushing down 5 big end of sand paper, and the small end face of chamfering device 1 is detachable
The guiding axis 3 being equipped with for pushing down 5 small end of sand paper；
The external side of pressing plate 2 is equipped with the drive shaft 7 that driving chamfering device 1 rotates, and is arranged on the axle body of the guiding axis 3
Sheath 4, sheath 4 are hollow cylindricality ladder nested structure, and the outer diameter of 4 small end of sheath is according to the connector to chamfer machining part 6
Depending on the aperture in hole, the drive shaft 7 and guiding axis 3 are on the same axis.
Further, the first internal thread hole 12 is equipped among the small end face of the chamfering device 1, among the large end face of chamfering device 1
Equipped with the first stud 11；The pressing plate 2 is equipped with and matched second internal screw thread of the first stud 11 away from the centre of 7 side of drive shaft
Hole 21；One end of the guiding axis 3 is equipped with and matched second stud 31 of the first internal thread hole 12.
Further, the depth of second internal thread hole 21 is greater than the thickness of pressing plate 2.
Further, the diameter dimension of pressing plate 2 is consistent with the diameter dimension of 1 large end face of chamfering device.
Further, the pressing plate 2 is structure as a whole with drive shaft 7.
Further, the chamfering device 1 is structure as a whole with the first stud 11.
Be between the utility model chamfering device 1 and guiding axis 3, between chamfering device 1 and pressing plate 2 using being spirally connected connection, can
It carries out splitting and reorganizing to be not much different since the connector aperture on aircaft configuration substantially changes in a certain range, so selected one
By the depth of feed motion the chamfering grinding in different-diameter hole may be implemented, in order to prevent in the chamfering device 1 of a size
The directly contact nipple orifice inner wall of guiding axis 3 causes to wear, and needs to be equipped with and 3 diameter dimension of guiding axis and connector aperture size phase
The protection bushing 4 of adaptation, by replacing various sizes of guiding axis 3 and sheath 4, it can be achieved that the nipple orifice of different-diameter size is fallen
Axial feed guiding role when angle processes.
What drive shaft 7 can be connect with hand-held pneumatic drill, pneumatic drill provides rotary power, is connected by pressing plate 2 and 1 screw thread of chamfering device
It connects, drives 1 rotary motion of chamfering device, the ablation of chamfering device 1 derives from the sand paper 5 wrapped up outside chamfering device 1, by leading
The sand paper 5 of the large and small end face of chamfering device 1 is forced to axis 3, pressing plate 2 and 1 screw-threaded coupling of chamfering device, realizes 1 rotary motion of chamfering device
When work, sand paper 5 is driven to be ground filleted junctions or bushing.
When being worked using this tool:
(1) 1 outer surface of chamfering device is wrapped into sand paper 5 first, for the pressing plate 2 of hand-held pneumatic drill selection of dimension package size
And drive shaft 7, pressing plate 2 are threadedly coupled with chamfering device 1, tighten screw thread, to compress 1 big end sand paper 5 of chamfering device, prevent from loosening.
(2) guiding axis 3 of package size, guiding axis 3 and chamfering device 1 are secondly chosen for different connectors, bushing aperture
It is threadedly coupled, tightens screw thread, to compress the sand paper 5 of 1 small end of chamfering device, prevent from loosening.
(3) it after chamfering device 1, pressing plate 2 connect integral with guiding axis 3, is connect with hand-held pneumatic drill, pays attention to hand-held pneumatic drill rotation
When to turn direction be clockwise, spiral shell that the screw thread and chamfering device 1 that the chamfering device 1 of design is connect with pressing plate 2 are connect with guiding axis 3
Line all should be right-handed thread, prevent in process, be threadedly coupled and loosen.
(4) before to be processed, the sheath 4 to match with nipple orifice, 3 size of guiding axis to chamfer machining part 6, sheath are chosen
4 small end and nipple orifice is clearance fit relationship, so needing to fix sheath 4 by a bit manipulation worker is hand-held in processing.
(5) finally start hand-held pneumatic drill, carry the direction axial rotary feeding fortune that facing attachment is determined along guiding axis 3
It is dynamic, drive the rotation of sand paper 5 butt joint, bushing to carry out grinding chamfer machining.
The characteristics of the utility model facing attachment:
(1) according to the angle for needing chamfering, it may customize the chamfering device 1 of common angle, commonly use 45 ° of chamferings on aircraft, it can also root
According to the chamfering device 1 for needed for different manufacturings, customizing different angle, the versatility of the utility model facing attachment is embodied.
(2) for the connector of different pore size, it is only necessary to guiding axis 3, the sheath 4 of a series of package sizes are customized, without more
Chamfering device 1 is changed, the connector to more size ranges, the work of bushing chamfer machining can be realized.
(3) this facing attachment does not use grinding wheel structure, because grinding wheel need to re-replace once abrasion, customizes dedicated different
Shape grinding wheel program is cumbersome, at high cost.What is wrapped up outside this device chamfering device 1 is the most common sand paper 5, by replacing sand paper 5, energy
Guarantee that grinding work is persistently gone on smoothly, greatly reduce cost, thick, fine grained specification sand paper 5 can realize corase grinding cut,
Fine grinding is cut, and the surface quality after chamfering is also higher than technical requirements, embodies this facing attachment low cost, and practicability is stronger.
(4) aircraft enters outside frame, outfield wants real in the case where no Special finishing machine and Special chamfering cutter
Existing component banjo fixing butt jointing chamfer angle technique has process characteristic small in size, portable, compared with strong adaptability using this facing attachment.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
