Description
Technical field
Dry gas seals field is the utility model is related to, the secondary groove depth measurement dress of particularly a kind of Dry Gas Seal friction
Put.
Background technology
At present, Dry Gas Seal friction pair uses SIC materials, and laser processes required groove profile in polished surface, groove
Deep is usually 0.008-0.0012mm or so.In general, measurement groove depth is measured using sample card, but sample card can only measure
Go out whether groove is consistent with sample card, actual grade for groove and require depth there are how many deviation to learn, also just can not
Show whether actual groove depth meets design requirement.
Utility model content
The main purpose of the utility model is that overcome drawbacks described above of the prior art, propose it is a kind of it is simple in structure, into
The secondary groove depth measuring device of this low, easy to operate Dry Gas Seal friction.
The utility model adopts the following technical solution：
A kind of secondary groove depth measuring device of Dry Gas Seal friction, it is characterised in that：Including base, fixed frame and torsional spring
Comparator；It is secondary to place Dry Gas Seal friction that the base is equipped with working face；The fixed frame is fixed on base；The torsional spring ratio
It is fixed on compared with instrument on fixed frame, and its measuring staff end is contacted to detect groove depth with the secondary measured position of Dry Gas Seal friction.
Preferably, some cushion sockets have been further included, which is fixed on the base bottom.
Preferably, the fixed frame includes column and stent；The column is fixed on base and normal thereto；The stent one
End is fixed at the top of column and normal thereto；The twisted-coil comparator is fixed on the stent other end.
Preferably, the stent is secured by bolts on the column.
Preferably, the stent other end is equipped with the mounting hole of up/down perforation.
Preferably, the fixed frame is fixedly connected by bolt with the base.
From the above description of the utility model, it can be seen, compared with prior art, the utility model has following beneficial to effect
Fruit：
1st, the utility model apparatus structure is simple, cost is low, easy to operate, also has the advantages that precision is high, speed is fast, is
The secondary use of Dry Gas Seal friction provides reliable ensure.
2nd, the utility model device is provided with cushion socket in base bottom, in groove depth measurement process, can play stable bottom
The effect of seat, further ensures that the accuracy of measurement structure.
3rd, the device of the utility model, its fixed frame include column and stent, column and base, stent and column, torsional spring
Locked between comparator and stent by bolt, it is simple in structure, firm.
4th, the device of the utility model, it uses twisted-coil comparator, in a linear relationship with angle of revolution using axial elongation
Torsional spring silk as main amplifier element, the straight-line displacement of measuring staff is converted to the angular displacement of pointer, the groove depth precision measured is high,
It is convenient to read.

Embodiment
Below by way of embodiment, the utility model will be further described.
Referring to figs. 1 to Fig. 3, a kind of secondary groove depth measuring device of Dry Gas Seal friction, including base 10, fixed frame 20
With twisted-coil comparator 30 etc..The base 10 is equipped with working face 12, for placing Dry Gas Seal friction pair 40,10 bottom of base
Face is fixed with four cushion sockets 11, respectively on four angles of base 10, plays the role of Steady base 10.
Fixed frame 20 includes column 21 and stent 22, which is fixed on base 10 by bolt 50 and leans on nearside
Portion, and it is vertical with working face 12.The top of column 21, and normal thereto, stent 22 are fixed in 22 one end of stent by bolt 50
The other end is equipped with the mounting hole 23 of up/down perforation.
Twisted-coil comparator 30 is secured across the mounting hole 23 on stent 22, and a bolt 50 is turned round through the end of stent 22 with compressing
Spring comparator 30.The twisted-coil comparator 30 is equipped with dial plate 32 and measuring staff 31, which is equipped with pointer.31 end of measuring staff with
The measured position contact of Dry Gas Seal friction pair 40, which is seal groove position.
The twisted-coil comparator 30 is using the axial elongation torsional spring silk in a linear relationship with angle of revolution as main amplification member
The straight-line displacement of measuring staff 31, is converted to the angular displacement of pointer by part.Its main element is that cross section is 0.01mm × 0.25mm, by
The torsion film that centre is twisted into both ends or so.During measurement, measuring staff 31 is moved along the seal groove of measured position from high point to low spot,
Lever swing is promoted, at this moment internal torsion film can be stretched or shorten, and cause torsion film to rotate, make throw of pointer, pass through reading
Total indicator reading is taken to can obtain the groove depth of seal groove 41.
The above is only the specific embodiments of the present invention, but the design concept of the present invention is not limited thereto,
All non-essential modifications to the present invention made by this concept, should all belong to the row for invading scope of protection of the utility model
For.
