Description
Technical field
Basis is the most practical newly relates to field of tool, particularly to the dismantling device of a kind of temperature field hardness plug.
Background technology
Piston is as one of the key components and parts of engine, and its operation conditions is directly connected to high-speed boosting electromotor
Functional reliability and useful life longevity, directly influence the discharge performance of electromotor simultaneously.Piston running environment is the harshest,
One, it is necessary to bear the pressure of high-pressure gas outburst, the inertia force of back and forth movement that speed is exceedingly fast, also lateral pressure and frictional force
The mechanical load of quasi-periodic；Its two, piston-top surface bears transition high-temperature fuel gas effect, makes top land or even whole piston
Temperature is the highest, and skewness, each spot temperature gradient is big, causes thermal stress and thermal deformation that piston is the biggest, seriously
Time piston-top surface can be caused to ftracture.So during designing and developing, piston is carried out temperature field test is necessary.Live
Plug is in high-speed motion state at work, and wanting the actual each position of measurement piston operating temperature under each working condition is
And difficulty.
At present, usual method has easily holds alloy measurement method, hardness plug measurement method, thermo-color measurement method and thermocouple
Measurement method etc..Easily holding alloy measurement method workload big, can affect piston temperature distribution and intensity, measurement error is relatively big, can only survey
Go out some temperature range.Comparison many be hardness plug measurement method, the temperature of the multiple point of piston can be surveyed, piston temperature is divided
The impact of cloth and intensity is little, and error is relatively small.
During hardness plug measuring method (piston temperature field), at piston combustion bowl center, bottom of combustion chamber, piston aditus laryngis, work
The screwed hole of the position processing appropriate sizes such as plug end face, annular groove neighbouring, piston cavity, piston-pin boss, is installed to hardness plug
Screwed hole, dress recurrence motivation after by specific operating condition of test run test, after test, hardness plug is pressed diverse location labelling,
Retract, by the hardness determination to plug hard after test, obtain its temperature suffered in process of the test, and each position of piston
Temperature.
But, in the process of the test of temperature field, mounting or dismounting hardness plug is the most crucial, needs to hold accurately moment, the most too small
Hardness plug can be caused to come off in engine operation process.Conference of exerting oneself causes the sliding tooth of hardness plug or cracking, thus cannot tear open
Take.Existing mounting or dismounting hardness plug is the inner hexagon spanner of φ 1.5mm, and inner hexagon spanner holds easy to slip teeth, and service life is too
Short, body dimension is the least, is not easy to mounting or dismounting piston cavity hardness plug, it is impossible to lengthens, is not easy to firmly, and inner hexagon spanner leads to
It is often a whole set of (from φ 1.5mm～φ 10mm), and mounting or dismounting hardness plug is only with wherein minimum (φ 1.5mm), has worn and torn and has i.e. lost
Abandoning, taking less than of other sizes is the most cumulative, wastes resource.
The information being disclosed in this background section is merely intended to increase the understanding to this practical new general background, and
It is not construed as recognizing or imply in any form this information structure existing well known to persons skilled in the art
Technology.
Practical new content
This practical new purpose is to provide the dismantling device of a kind of temperature field hardness plug, increases the service life, and uses
Convenient.
For achieving the above object, this practical dismantling device newly providing a kind of temperature field hardness plug, including: interior hexagonal
Bar, this interior hexagonal bar is arranged at intervals with some circle broken lines, interior hexagonal bar can be formed after fractureing along broken line new in six
Angle spanner；And extension bar, one end of this extension bar is provided with hexagonal hole vertically, and interior hexagonal bar is rear in inserting hexagonal hole to be used
Interior hexagonal bar is locked together by lock-screw with extension bar.
Preferably, the tail end of extension bar is L-shaped or T-shaped.
Preferably, extension bar is circular pin.
Compared with prior art, basis is the most practical newly to be had the advantages that by a kind of interior hexagonal bar of design, and this is interior
It is arranged at intervals with some circle broken lines on hexagonal bar, when the sliding tooth of dismantling device abrasion, can fracture along broken line, continue to make
With, solve the easy to wear sliding tooth problem of the i.e. inner hexagon spanner of hardness plug mounting or dismounting tools, extend tool life, improve and make
By convenience, substantially increase work efficiency.

Fig. 1 is the structural representation of the dismantling device according to this practical new temperature field hardness plug, interior hexagonal bar with add
Stock is not connected with；
Fig. 2 is the enlarged drawing of the dismantling device according to this practical new temperature field hardness plug, it is shown that lock-screw；
Fig. 3 is the partial schematic diagram of interior hexagonal bar in the dismantling device according to this practical new temperature field hardness plug.
Detailed description of the invention
Below in conjunction with the accompanying drawings, this practical new detailed description of the invention is described in detail, it is to be understood that this practicality
The protection domain that type is new is not limited by detailed description of the invention.
Explicitly indicating that unless otherwise other, otherwise in entire disclosure and claims, term " includes " or it becomes
Change and such as " comprising " or " including " etc. will be understood to comprise stated element or ingredient, and do not get rid of other yuan
Part or other ingredient.
As shown in Figure 1 to Figure 3, according to the dismounting work of originally a kind of temperature field hardness plug of practical new detailed description of the invention
Tool, including interior hexagonal bar 1 and extension bar 3, this interior hexagonal bar 2 is arranged at intervals with some circle broken lines 11 (seeing Fig. 3), interior
Hexagonal bar 1 can form new inner hexagon spanner after fractureing along broken line 11.One end of extension bar 3 is provided with hexagon vertically
Hole, interior hexagonal bar 1 inserts after in hexagonal hole and is locked together with extension bar 3 by interior hexagonal bar 1 with lock-screw 2.
In such scheme, interior hexagonal bar 1 can be designed as long 80mm, diameter 1.5mm, its be mainly characterized by bar every
Certain distance have a circle broken line 11 (blade of similar wallpaper cutter, has line with blade, can fracture along line with blunt,
The new knife edge occurs), when the sliding tooth of dismantling device abrasion, can fracture along broken line 11, be continuing with.Extension bar 3 can set
Being calculated as long 80mm, φ 6mm, mainly have lengthening and upper moment loading, there are the hexagonal hole of φ 1.5mm, interior hexagonal bar 11 in its one end
Insert such hexagonal hole to be locked by lock-screw 2, prevent from getting loose.
As a kind of preferred embodiment, the tail end of extension bar 3 is L-shaped or T-shaped.In this programme, the tail end of extension bar 3 is
L-shaped or T-shaped, moment in convenience.
As a kind of preferred embodiment, extension bar is circular pin.
To sum up, the dismantling device of the temperature field hardness plug of the present embodiment, by design a kind of in hexagonal bar 1, and this interior six
It is arranged at intervals with some circle broken lines 11 on angular pole 2, when the sliding tooth of dismantling device abrasion, can fracture along broken line 11, continue
Use.Solve the easy to wear sliding tooth problem of the i.e. inner hexagon spanner of hardness plug mounting or dismounting tools, extend tool life, improve
Property easy to use, substantially increases work efficiency.
The aforementioned description to this practical new specific illustrative embodiment illustrates that and the purpose of illustration.These
Describe and be not wishing to this most practical newly defined for disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
