In accompanying drawing, labelling is as follows：
Movable block 1, bolt 2, side plate 3, limited block 4, reinforcing cylinder 5.
Specific embodiment
This utility model embodiment discloses a kind of fixture for ring specimen, to clamp all kinds of rings in commercial production
Shape sample, conveniently carries out the detection work of part.
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under the premise of making creative work
The every other embodiment being obtained, broadly falls into the scope of this utility model protection.
Refer to Fig. 1 and Fig. 2, the main view knot of the fixture for ring specimen that Fig. 1 provides for this utility model embodiment
Structure schematic diagram, the left view structural representation of Fig. 1 that Fig. 2 provides for this utility model embodiment.
Embodiment of the present utility model provides a kind of fixture for ring specimen, including a pair of movable block 1 be used for
By the connecting shaft of movable block 1 and external connection, the thickness of movable block 1 is preferably greater than the thickness of ring specimen to be detected, connects
Axle is respectively fixedly connected with movable block 1, and the axis of connecting shaft is located along the same line, if a pair of relative face of movable block 1 is
Inner side, then connecting shaft be respectively positioned on the outside of movable block 1, the outline of movable block 1 is matched with the Internal periphery of ring specimen.
During the fixture for ring specimen that application above-described embodiment provides, near placing between movable block 1, then by ring
At the outline of movable block 1, then external structure drives connecting shaft to separate to shape sample hoop, and movable block 1 is also separately carried out therewith
The stretching of ring specimen, and then record the relevant parameter of ring specimen.Using split-type structural, the outline of movable block 1 simultaneously
Match with the Internal periphery of ring specimen, ring specimen smoothly can be positioned in this fixture, and make ring specimen
By uniform tensile force, the size and dimension of movable block 1 can also be closed according to the size and dimension of ring specimen simultaneously
Reason collocation, it is not necessary to produce the standard component of ring specimen, is adapted to the ring part in various ring-shaped work pieces or part
Point.It is noted that because ring specimen not national standard part, therefore this fixture and corresponding test machine need to difference
Contrast after under state, the ring specimen of (such as room temperature and high temperature two states) is tested, to obtain characterizing ring specimen
Strengthening effect index.
In order to optimize the using effect of movable block 1 in above-described embodiment, movable block 1 is specially equivalently-sized arch cylinder
Movable block 1, the circular arc portion phase of arch cylinder movable block 1 deviates from.Preferably employ equivalently-sized arch cylinder movable block 1 conduct
A part for fixture, a pair of movable block 1 symmetrical configuration, the circular arc portion phase of arch cylinder movable block 1 deviates from, and can accurately place
Annular sample.Because in ring specimen, annular sample occupies the main body in market, therefore preferably symmetrical movable block 1 is used for
Clamping annular sample.
For example in a specific embodiment, piston is the core zero that heat energy changes in electromotor mechanical energy
Part, with country a few days ago increasingly stricter to the emission request of automobile so that bear required for piston to fire pressure also more next
Higher, especially top land throat site bears thermic load more and more higher, in the urgent need to local strengthening technical finesse.Send out at present
The technology popularization and application such as motivation piston throat site laser forming remelting, beam-plasma remelting and quick cooling, but these
Local strengthening technique effect is necessarily required to concrete tensile strength numerical representation method, the therefore need of the tensile strength of measurement annular sample
Ask also more and more stronger.
Certainly, this utility model does not limit the concrete shape of ring specimen, and non-circular sample can also adopt this folder
It is only necessary to the outline of movable block 1 is matched with the Internal periphery of ring specimen, erose ring specimen is also for tool clamping
Can be good fit.
In another specific embodiment, movable block 1 is fixedly connected with limited block 4, limited block 4 by side plate 3 respectively
Internal periphery match with the outline of ring specimen.Be preferably provided with that the outline of Internal periphery and ring specimen matches is spacing
Ring specimen can be limited in movable block 1 around by block 4, without loosely or stretching because of installation in detection process
Rupture and eject this fixture, to avoid danger and hurt relevant staff.
In order to optimize the using effect of connecting shaft in above-described embodiment, connecting shaft is specially fixedly connected with limited block 4
Bolt 2.Preferably employ bolt 2 as connecting shaft, there is higher tensile strength, therefore also just there is longer service life,
Easy to operate when being connected with external device (ED) simultaneously, and bolt 2 as standard component can damage when change at any time, in order to avoid delaying
The progress of detection work.Further, it is also possible to preferred bolt 2 and the dismountable connection of limited block 4, so either component damages wherein
Bad when, just can be without integral replacing, but the part removing wherein damage is individually replaced, cost-effective.Certainly also may be used
Using from other parts as connecting shaft, as long as so that limited block 4 or movable block 1 are connected with external structure and permissible
Bear certain tensile force, protection domain of the present utility model is belonged to using any form of connecting shaft.
In order to optimize the using effect of bolt 2 in above-described embodiment, bolt 2 is fixedly connected with reinforcing cylinder 5.Due to spiral shell
The tensile strength of bolt 2 is limited, when ring specimen has very high tensile strength it may be preferred to be fixedly connected on bolt 2
Reinforce cylinder 5, drastically increase the tensile strength of bolt 2, in order to avoid this fixture is also not up to maximum tension in ring specimen
Just as tensile strength is not damaged during power.
Based on the fixture providing in above-described embodiment, this utility model additionally provides a kind of tensile strength test machine, and this resists
Tensile strength test machine includes any one fixture in above-described embodiment.Because this tensile strength test machine employs above-described embodiment
In fixture, so the beneficial effect of this tensile strength test machine refer to above-described embodiment.
In this specification, each embodiment is described by the way of going forward one by one, and what each embodiment stressed is and other
The difference of embodiment, between each embodiment identical similar portion mutually referring to.
Also, it should be noted in this manual, such as first and second or the like relational terms be used merely to by
One entity or operation are made a distinction with another entity or operation, and not necessarily require or imply these entities or operation
Between there is any this actual relation or order.And, term " inclusion ", "comprising" or its any other variant meaning
Covering comprising of nonexcludability, so that including a series of process of key elements, method, article or equipment not only include that
