Method.
Background technique
Traveling probe is important testing tool, and function is to drive it to move by mobile mechanism and carry out data acquisition,
Since traveling probe needs the mounting hole across shift mechanism when in use, therefore traveling probe impulse structure full-size is not answered
More than the size of displacement mechanism mounting hole, therefore it is restricted the size of impulse structure.
For this purpose, the currently impulse structure of mobile impulse probe mostly design uses and mostly connects with elongated pressure guiding pipe, and by sebific duct
The mode connect, as shown in Figure 1.In the prior art scheme, pressure guiding pipe 3 is made by stainless steel tube, one end pass through guide pipe 1 with
Measuring point 5 connects, and the other end and impulse connect the welded connecting of mouth 4, and blanking cover 2 is arranged to seal backwards to one end of measuring point 5 in guide pipe 1
Stifled guide pipe and fixed pressure guiding pipe 3.When using above-mentioned traveling probe, the axial direction of pressure guiding pipe 3 and the axial direction of guide pipe 1 need to be first adjusted
In parallel, impulse is then connect mouth 4, pressure guiding pipe 3, guide pipe 4 to pass through displacement mechanism mounting hole, and impulse is connect mouth 4 and passes through sebific duct
It is connect with test equipment.
Above scheme has the disadvantage in that
1, since traveling probe measuring point 5 is more, should mutually there is more pressure guiding pipe 3 to be attached thereto, for avoid impulse connect mouth 4 it
Between interfere, the different length of pressure guiding pipe 3 need to be designed, in the case where its number is more, part pressure guiding pipe 3 is longer, cause
It is set to be easily bent or even fracture.
2, after being used for multiple times, expendable deformation can be generated by the elongated pressure guiding pipe 3 that stainless steel tube makes, caused
It is difficult to the mounting hole across displacement mechanism, and will affect the accuracy of experiment test.
3, at it in use, impulse connects mouth 4 and sebific duct junction is easy gas leakage, and dismounting is cumbersome.
Summary of the invention
It is above-mentioned to overcome or alleviated by the object of the present invention is to provide a kind of traveling probe impulse structure and its application method
The problem of at least one aspect.
The technical scheme is that
A kind of traveling probe impulse structure, comprising:
Impulse front end is cylindrical body, opens up through-hole along axial direction；
Impulse rear end, one end are fixedly connected with one end of impulse front end；
One side is plane, and opens up multiple threaded holes along the vertical direction of plane, and threaded hole bottom opens up inner conical surface, shape
At interior cone space；
Its other side axially opens up groove along through-hole, and groove is connected to through-hole, and opens up multiple tracting pressuring holes in groove top surface,
Tracting pressuring hole communication groove and interior cone space；
Pressure guiding pipe, one end passes through through-hole and enters groove, and is connected to tracting pressuring hole.
Preferably, the end face that pressure guiding pipe is located at one end in groove is welded and fixed with groove inner wall.
Preferably, filler is filled in groove.
Preferably, filler is filled in through-hole.
The application method of above-mentioned impulse structure, comprising the following steps:
Pressure guiding pipe 3 is passed through guide pipe 1 backwards to one end of impulse front end 6 and is connected to measuring point 5 by the first step；
Impulse front end 6 is fixed on inside guide pipe 1 by second step；
Test equipment is connect with threaded hole by being threadedly engaged by third step.
It is illustrated it is an advantage of the current invention that providing a kind of traveling probe impulse structure and being used for method,
The structure avoids the bending of pressure guiding pipe, becomes by pressure guiding pipe being arranged in the through-hole and impulse rearmost flute of impulse front end
Shape；Meanwhile its using when by impulse front end cooperation be fixedly installed on inside guide pipe, can guarantee positioning accuracy, and
It is threadedly engaged by threaded hole with test equipment to connect and connects mouth instead of impulse in the prior art and connect with test equipment by sebific duct,
The leakproofness for thereby ensuring that junction avoids the leakage of fluid here；In addition, the processing is simple for the structure, difficulty of processing
It is small, convenient for its popularization and application.
