Description
Technical field
The utility model belongs to maintenance tool range, more particularly to the aviation of a kind of raising centering precision and puncturing rate is attached
Part centering punching tooling.
Background technology
When aviation accessory repairs, the centering punching of workpiece is conventional to use two methods：One, it is manually felt relieved and is consolidated
It is fixed, and the shell of most of workpiece and irregular, it is not easy to which that control and fixed, artificial alignment will produce large error, easily cause
Unbalance stress causes workpiece deflection, and weaker workpiece shell is made to deform, and secondary destruction may be caused to workpiece；Or
It is felt relieved using rod tooling, determines to remove rod tooling behind position and punch, but such method also can not be complete
Suitably workpiece is fixed entirely, it is larger so as to cause centering error, and also punching is inconvenient, needs to carry out tooling in the process
Dismounting.Therefore, it is necessary to design a kind of aviation accessory centering punching tooling that can improve centering precision and puncturing rate,
Overcome the shortcomings of existing centering punching tooling.
Utility model content
The purpose of this utility model is a kind of raising centering precision of deficiency proposition for above-mentioned existing disassembling fixture and beats
The aviation accessory centering punching tooling of hole rate, which is characterized in that the centering punching tooling integrates centering and punching, centering
The centration axis 3 of punching tooling can be divided into four sections from top to bottom, and diameter successively increases, and centration axis 3 sequentially passes through from top to bottom
Tool base plate 2, workpiece 1, the mandrel of feeling relieved coaxially are fixed them by nut 6 and gasket 5 after coordinating axle sleeve 7 and cyclic annular gland 4；
Wherein, 4 interior diameter of cyclic annular gland is identical as the diameter of 3 first segment of centration axis, and cyclic annular gland 4 is provided with and hole on workpiece 1
The one-to-one hole in position, and with there are two pin 8,8 bottom of pin carry the screw thread to match with workpiece 1, on cyclic annular gland 4
Side is also equipped with the drill bushing 9 that location hole is beaten for workpiece, and the diameter of 3 second segment of centration axis coordinates axle sleeve 7 and 1 top of workpiece by mandrel
Centre bore coordinates；The diameter of 3 third section of centration axis coordinates with 1 middle part centre bore of workpiece；The diameter and work that the 4th section of centration axis 3
1 central bore of part and the cooperation of tool base plate centre bore；1 lower part of workpiece passes through screw fixed hole 12 and tool base plate threaded hole 13
Connection.
The maximum height that the ring-type gland is moved in the vertical direction in centration axis first segment by with centration axis top screw thread
The nut and gasket to match is limited.
8 bottom of the pin carries the screw thread to match with workpiece 1, passes through pinhole 10 and workpiece 1 on cyclic annular gland 4 right
Threaded hole is answered to connect.
The utility model advantageous effect is centration axis can combine closely with workpiece, realize that horizontal direction is precisely fixed, work
The side's of loading onto gland coordinates with nut realizes that workpiece vertical direction is precisely fixed, since punch position is at a distance from the hole on workpiece
And angle be it is fixed, can by measure obtain, therefore on gland measure position punched and match with after drill bushing, can be same
When on gland the pin end of hole and workpiece hole can be connected with workpiece realization by screw thread while reinforce
Punch position is determined, it is achieved that being punched while centering, having saved time cost in this way and dismantling workpiece
Cost of labor improves puncturing rate, and can make the weak part of workpiece to avoid unbalance stress when punching, workpiece deflection
Deform, ensure by centering punching aviation accessory will not secondary injury, this centering punching tooling is simple in structure, be easy grasp
Make, vdiverse in function, error is smaller.
Description of the drawings
Fig. 1 is centering punching tooling constructional appearance figure.
Fig. 2 is centering punching tooling structural section figure.
Specific implementation mode
The utility model proposes a kind of raising centering precision and the aviation accessory centering punching toolings of puncturing rate, tie below
Attached drawing is closed to be explained.
Fig. 1 is centering punching tooling constructional appearance figure.Fig. 2 is centering punching tooling structure AA sectional views.As shown in the figure, should
Centering punching tooling integrates centering and punching, and the centration axis 3 for punching tooling of feeling relieved can be divided into four sections from top to bottom, and straight
Diameter successively increases, and centration axis 3 sequentially passes through centering tool base plate 2, workpiece 1, mandrel cooperation axle sleeve 7 and cyclic annular gland from top to bottom
It is by nut 6 and gasket 5 that they are coaxial fixed after 4；Wherein, the diameter phase of 4 interior diameter of cyclic annular gland and 3 first segment of centration axis
Together, the maximum height that cyclic annular gland is moved in the vertical direction in centration axis first segment is by the spiral shell that matches with centration axis top screw thread
Female and gasket is limited.Cyclic annular gland 4 be provided with the one-to-one hole in the position of hole on workpiece 1, and with there are two pin
Son 8,8 bottom of pin carry the screw thread to match with workpiece 1, pass through the screw thread corresponding with workpiece 1 of pinhole 10 on cyclic annular gland 4
Hole connects.4 top of cyclic annular gland is also equipped with the drill bushing 9 that location hole is beaten for workpiece, and drill bushing position measures and calculates by accurate, just
In punching.The diameter of 3 second segment of centration axis coordinates axle sleeve 7 to coordinate with 1 upper portion central hole of workpiece by mandrel；3 third of centration axis
The diameter of section coordinates with 1 middle part centre bore of workpiece；The diameter that the 4th section of centration axis 3 and 1 central bore of workpiece and tool base plate
Centre bore coordinates；1 lower part of workpiece is connect by screw fixed hole 12 with tool base plate threaded hole 13.
The diameter that makes is consistent with pore diameter by tooling center is according to workpiece pore size determines for the utility model
Mandrel 3 coordinate axle sleeve 7, the shell horizontal direction of workpiece is precisely fixed, by cyclic annular gland 4 hole with it is each in tooling 1
After hole corresponds to, using can vertical direction adjust and pass through nut 6 and the fixed cyclic annular gland 4 of gasket 5, tool base plate 2 of feeling relieved
Workpiece 1 is fixed in vertical direction, realize precisely centering, with across cyclic annular gland hole and on workpiece carry hole two
A pin 8 is reinforced workpiece 1 by bottom end screw thread, while punch position is determined；It is realized across drill bushing 9 using drill bit and is finally beaten
Hole target.
