Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1 is borescope schematic diagram, and wherein dotted line frame is the high-axiality interface arrangement of the utility model, including one and school
The connecting shaft 1 of the connection of target mirror 4, the top cover 2 being mounted in connecting shaft 1 and tube expansion 3.
As shown in Fig. 2, connecting shaft 1 is divided for four parts, including connecting pin 11, interlude 12, cone segments 13, tail end 14, company
End is connect 11 to connect with borescope 4, top cover 2 is mounted on interlude 12, can before and after along the spiral shell without a head for being fixed on interlude 12
15 sliding of nail can hold and play the purpose for pushing up loose tube expansion 3 backward, borescope easy to disassemble.Cone segments 13 are a cones,
There is certain slope, closer to tail portion, diameter is smaller, thinner.Tube expansion 3 is mounted in cone segments 13, when tube expansion 3 is located at cone segments 13
Tail portion when, tube expansion 3 is in relaxed state, when installing borescope, passes through the convex 31 of 3 front end of tube expansion, the inner wall of borescope
Tube expansion 3 is pushed to the head of cone segments 13, tube expansion 3 is gradually expanded to all directions, until completely tight with the inner wall of borescope
Contiguity touching.There is pin 16 without a head in cone segments 13, can fix tube expansion 3 can only slide back and forth, and cannot rotate around connecting shaft.Tail
Retaining ring is installed on end 14, can prevent the tube expansion 3 in cone segments 13 from falling off.
As shown in figure 3, there is helicla flute 21 in top cover 2, cooperates with the headless screw 15 in connecting shaft 1, keep top cover 2 former
After rotate, to convert the thrust to the top front and back of tube expansion 3 for rotary force of the hand to top cover 2.Top cover 2 is a handgrip part,
Borescope or collimator are being installed) when, can hold top cover 2 easily makes borescope insertion to calibration equipment, is seated and inserts firmly；Disassembly
When borescope, top cover 2 can be rotated, relaxed state is arrived on the top of tube expansion 3, borescope is facilitated to take out to calibration equipment.
Top cover 2 designs, i.e., also easy to disassemble convenient for hand-held, especially when environment temperature is too low, borescope contact surface with to school
When equipment contact surface is pasted, top cover 2 can be convenient operator and unload borescope.
As shown in figure 4,3 front and back end of tube expansion is uniformly provided with several troughs 32,32 cross arrangement of front and back trough, to improve
The precision of expansion.There is circular aperture 33 in the port of trough 32, to discharge influence of 3 expansive force of tube expansion to 3 central structure of tube expansion.
The outer diameter of tube expansion 3 is negative common difference to calibration equipment internal diameter, and there is a convex 31 on 3 head of tube expansion, outer diameter be greater than in calibration equipment
Diameter plays fixed tube expansion 3 and the purpose to calibration equipment.Tube expansion 3 selects that the coefficient of expansion is good, anti abrasive material is made.
When specific operation, the course of work of borescope is installed are as follows:
One hand holds borescope, and another hand holds top cover 2, rotates top cover 2, and borescope or collimation are arrived in the top of tube expansion 3
The least significant end of instrument reaches fully relaxed non-distending state.
By tube expansion 3, slowly insertion is in calibration equipment, until 3 front convex 31 of tube expansion to calibration equipment with being in close contact,
Tube expansion 3 reaches complete distending state at this time.
Top cover 2 is rotated, it is disengaged with tube expansion 3, reaches spacing maximum rating.
Along borescope axial direction, firmly borescope is promoted in calibration equipment, is leaned on until inserting firmly, make 3 outer circle of tube expansion with to
Calibration equipment sufficiently combines, gapless.
Dismantle the course of work of borescope are as follows:
One hand holds borescope, and another hand holds top cover 2.Top cover 2 is rotated, the top of tube expansion 3 is arrived to the most end of borescope
End, reaches fully relaxed non-distending state.
Borescope is slowly extracted to calibration equipment, is put down gently to packing case.
The interface arrangement of the utility model can be such that borescope is in close contact with to calibration equipment, ensure that borescope and to school
The coaxial consistency of equipment, and precision will not be reduced with abrasion is used, to effectively increase calibration accuracy.
Compared with traditional interface structure, the interface structure of the utility model can significantly improve borescope concentricity and
Plug precision.Note: concentricity, the i.e. axis of borescope and the registration to calibration equipment axis.Precision is plugged, i.e., repeatedly from same
To in calibration equipment, into and out borescope, the registration of each secondary borescope axis.
It by replacing distinct interface structure, can be attached with different equipment, to ensure that borescope is (or quasi-
Straight instrument) different occasions can be used.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
