Description
Technical field
The utility model is related to a kind of telescopic plate nut drill jigs, belong to field of machining and machinebuilding technology.
Background technology
In Q400 and C systems class Aircraft Project, the plate nut type installed on aircraft is more, such as：MS21059、
The ears plate nut such as MS21069, MS21075, B02040065, B02040066, B0204077, MS21061, MS21071,
The monaurals plate nut such as B0204064, B0204076, and enormous amount, up to up to ten thousand.
At present in the production scene of Q400 and C series aircrafts, the aperture of each plate nut is not quite similar, this is just needed not
With the plate nut drill jig shape of model, each plate nut drill jig is only applicable to a kind of plate nut, meets production assembly need
It wants, large number of, tool management and the maintenance abnormality difficulty of live plate nut drill jig；Some plate nut holes are not suitable
Plate nut drill jig matches, and causes plate nut that can not install, if the plate nut drill jig positioning column diameter used is less than zero
Plate nut hole on part will be unable to the concentricity for ensureing plate nut drill jig positioning column and part upper pallet nut bore, in turn
Scrapping for part is caused, this both increases production cost.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of telescopic plate nut drill jig, the telescopic supporting plate spiral shells
Female drilling jig have it is easy to operate, adapt to that pore diameter range is wide, improves production efficiency, which reduces part to the full extent
Scrappage and reduce common plate nut drill jig quantity, controls cost to the full extent.
In order to solve the above problem, the specific technical solution of the utility model is as follows：A kind of telescopic plate nut drill jig, shell
It is equipped with spring cavity I and spring cavity II in vivo, spring I is equipped in spring cavity I, spring II, shell lower face are equipped in spring cavity II
It is connected with baffle, baffle operative end surface is set there are two mounting hole, and baffle operative end surface is connected with mandrel, mandrel clearing end and spring
I time end in contact, baffle operative end surface are connected with pin, and pin clearing end and II time end in contact of spring, mandrel and pin utilize gear
Plate gear is in shell and can freely stretch under the action of the spring.The shell is inverted trapezoidal.
The size of the baffle is corresponding with the horizontal ends size of shell.
It is connected with sectional nave in the mounting hole.
What the utility model was brought has the beneficial effect that：The telescopic plate nut drill jig utilization rate is high, service efficiency is high, suitable
With range is wide, easy to use, maintenance is simple, operability is especially strong, production cost is low.
Description of the drawings
Fig. 1 is telescopic plate nut Drilling Jig Structure schematic diagram.
Fig. 2 is telescopic plate nut drill jig operation chart.
Fig. 3 is that the telescopic support class nut drill jigs of Fig. 2 rotate 180 degree.
Wherein, 1- shells, 2- mandrels, 3- springs I, 4- baffles, 5- pins, 6- bushings, 7- spring cavitys I, 8- spring cavitys II,
9- springs II, 10- mounting holes.
Specific implementation mode
As shown in Figure 1, a kind of telescopic plate nut drill jig, shell 1 is interior to be equipped with spring cavity I 7 and spring cavity II 8, spring
It is equipped with spring I 3 in chamber I 7, is equipped with spring II 9 in spring cavity II 8,1 lower face of shell is connected with baffle 4,4 operative end surface of baffle
If there are two mounting hole 10, baffle 4 and shell 1 are connected using screw 12, and 4 operative end surface of baffle is connected with mandrel 2, and mandrel 2 is eventually
Not-go-end and I 3 times end in contact of spring, 4 operative end surface of baffle are connected with pin 5,5 clearing end of pin and II 9 times end in contact of spring, the heart
Axis 2 and pin 5 are kept off in shell using baffle 4 and can freely be stretched under the action of the spring.
The shell 1 is inverted trapezoidal.
The size of the baffle 4 is corresponding with the horizontal ends size of shell 1.
It is connected with sectional nave 6 in the mounting hole 10.
As shown in Fig. 2, first mandrel 2 is inserted into corresponding hole and plate nut drill jig is made closely to be pasted with piece surface
It closes, at this moment pin 5 is in retracted state, and drill bit is put into mounting hole 10, and rotation plate nut drill jig complies with drawing and wants
After asking, according to first rivet hole of hole drill on drilling specification and plate nut drill jig, then rotating plate nut drill jig makes pin
Nail 5 is inserted under the action of spring II 9 in first rivet hole being drilled, and second riveting is bored after so that drill jig is fitted closely with part
Nail hole.Plate nut drill jig is unloaded from part, completes plate nut boring work.The device is effectively avoided due to zero
Aperture difference replaces plate nut drill jig on part, and the device is suitable for single ears plate nut hole, so as to shorten assembly
The purchase cost of period and reduction tool and the administration fee for reducing tool.
Above-described is only the preferred embodiment of the utility model.It should be pointed out that for the ordinary skill people of this field
For member, without departing from the principle of this utility model, several variations and modifications can also be made, also should be regarded as belonging to this
The protection domain of utility model.
