Outer circle be equipped with external screw thread, the inner circle of pipe is equipped with internal thread；It will by allen wrench when testing energy steering engine
Screw-thread bush blind end is screwed inwardly into mounting hole, and then energy steering engine is fixed in test equipment with screw again.
In preceding method, the hardness of the screw-thread bush is no more than the hardness at energy steering engine mounting hole.
In preceding method, the external screw thread of the screw-thread bush and the screw thread of mounting hole correspond to M10 × 1-6h；Screw-thread bush
Internal thread be M8 × 1-6H.
In preceding method, the internal thread of the screw-thread bush is parallel with the external screw thread of screw-thread bush.
In preceding method, the screw is M8 × 1-6h screws.
In preceding method, the length of the screw-thread bush is corresponding with mounting hole internal thread length.
According to a kind of safeguard structure for energy steering engine mounting hole adjustment process of the invention that the above method is constituted, including energy
Source steering engine is equipped with mounting hole on energy steering engine, and screw-thread bush, screw-thread bush and peace are provided in the mounting hole of energy steering engine
It fills hole to be threadedly coupled, the screw-thread bush is the closed circular tube shaped in one end, and the blind end of pipe is equipped with hexagonal hole, the outer circle of pipe
Equipped with the external screw thread being threadedly coupled with mounting hole, the inner circle of pipe is equipped with internal thread.
By adopting the above-described technical solution, compared with prior art, the present invention the present invention in mounting hole by increasing
The method of screw-thread bush protects mounting hole screw thread in the product testing stage, screw thread lining is removed after product testing well
Set, mounting hole is excellent, does not occur damaging caused by adjustment, delivery process.The internal and external threads of screw-thread bush are using parallel
Screw thread solves the problems, such as screw-thread bush intensity well.
Description of the drawings
Fig. 1 is the method schematic diagram of the present invention；
Fig. 2 is that the screw-thread bush of the present invention is packed into the structural schematic diagram of mounting hole；
Fig. 3 is the structural schematic diagram of the screw-thread bush of the present invention.
In figure label for：1- mounting holes, 2- screw-thread bushes, 3- hexagonal holes, 4- internal threads, 5- external screw threads, 6- energy steering engine,
7- is parallel.
Specific implementation mode
The present invention is described in further detail with reference to the accompanying drawings and examples.
The means of defence of a kind of energy steering engine mounting hole adjustment process of the present invention, as shown in Figure 1, this method is in the energy
It is threaded bushing 2 in the mounting hole 1 of steering engine 6, is formed and is protected in 1 thread surface of mounting hole of energy steering engine 6 by screw-thread bush 2
Sheath prevents screw from damaging mounting hole 1 when fastening energy steering engine 6.The length of screw-thread bush 2 and 1 internal thread length of mounting hole
It is corresponding.Screw-thread bush 2 is the closed circular tube shaped in one end, and the blind end of pipe is equipped with hexagonal hole 3, and the outer circle of pipe is equipped with external screw thread
5, the inner circle of pipe is equipped with internal thread 4；Screw-thread bush 2 is closed by allen wrench when testing energy steering engine 6
End is screwed inwardly into mounting hole 1, and then energy steering engine 6 is fixed in test equipment with screw again.The hardness of screw-thread bush 2 is little
Hardness at 6 upper installing hole 1 of energy steering engine.The external screw thread 5 of screw-thread bush 2 corresponds to M10 × 1- with the screw thread of mounting hole 1
6h；The internal thread 4 of screw-thread bush 2 is M8 × 1-6H.The internal thread 4 of screw-thread bush 2 is put down each other with the external screw thread 5 of screw-thread bush 2
Row 7.M8 × 1-6h screws are used with the screw of test.
According to a kind of safeguard structure for energy steering engine mounting hole adjustment process of the invention that the above method is constituted, such as Fig. 2
Shown in Fig. 3, which includes energy steering engine 6, mounting hole 1 is equipped on energy steering engine 6, in the mounting hole 1 of energy steering engine 6
It is provided with screw-thread bush 2, screw-thread bush 2 is threadedly coupled with mounting hole 1, and the screw-thread bush 2 is the closed circular tube shaped in one end, circle
The blind end of pipe is equipped with hexagonal hole 3, and the outer circle of pipe is equipped with the external screw thread 5 being threadedly coupled with mounting hole 1, and the inner circle of pipe is equipped with
Internal thread 4.
Embodiment
This example is as depicted in figs. 1 and 2.In order to be protected to the screw thread in mounting hole 1, spiral shell is increased in mounting hole 1
Line bushing 2, screw-thread bush 2 is packed into energy steering engine 6 before debugging, takes out screw-thread bush 2 after the completion of delivery, in energy steering engine 6
Adjustment, the screw thread in mounting hole is protected in delivery process.
The mounting hole 1 of energy steering engine 6 is the threaded hole of M10 × 1-6H, thus determines the external screw thread 5 of screw-thread bush 2
It is only M10 × 1-6h.Energy steering engine 6 all needs to install rudder using mounting hole 1 in load testing, dynamic test, vibration screening
Machine, in 600N m or so, vibration screening magnitude is 6.06g will influence the operating torque of load testing if mounting screw is too thin
Mounting screw intensity, causes security risk, by calculating, experiment, analysis and summary, determines that the outer diameter of mounting screw can only adjust
It just can guarantee that mounting screw can bear the intensity of load, vibration to φ 8, thus determine that the internal thread 4 of screw-thread bush 2 is M8
×1-6H。
When conventional design, when external screw thread is M10 × 1-6h, externally threaded smallest base diameter is φ 9, and internal thread 4 is M8 × 1-
When 6H, the maximum inner diameter of internal thread 4 is φ 9.Therefore, according to conventional design, calculated with dimension limit, screw-thread bush 2 it is inside and outside
Screw thread can run through.2 intensity of screw-thread bush can not ensure, in order to solve this problem, ensure the intensity of screw-thread bush 2, screw thread is served as a contrast
The internal and external screw thread of set 2 is designed as parallel 7 screw thread, so that the wall thickness of screw-thread bush is reached 0.5mm, which is addressed.Screw thread serves as a contrast
Set 2 is shown in Fig. 2.
