But the utility model is not limited to this, for example, this non-smooth surface can be formed by annular knurl.
In a specific embodiment of the present utility model, the depth of chase is more than or equal to the screw thread on fining twisted steel
Height.According to this specific embodiment it can be ensured that refining the stable connection between screw thread steel curved beam and holder.
In a specific embodiment of the present utility model, the outer surface of holder is in cone, the inner surface of connector
It is provided with the conical portion matching with the conical external surface of holder.When holder is coupled to connector, holder
Outer end project from the outer surface of connector.By such embodiment, holder and connector easily can be coordinated
And holder and connector can be conveniently separated, thus facilitate operator to be operated and ensured the validity coordinating.
In a specific embodiment of the present utility model, the outer surface of holder is provided with several spaced apart ditches
Groove.By this embodiment, the friction between holder and connector can be reduced, convenient use separates this two portions after finishing
Part.
The utility model provides a kind of relaxation testing machine fixture, can efficiently solve operation when sample skid and
Built on the sand the problems such as.
Brief description
Fig. 1 is the sectional view according to relaxation testing machine fixture of the present utility model；
Fig. 2 is the sectional view of the holder of relaxation testing machine fixture illustrating Fig. 1；And
Fig. 3 is the sectional view of the connector of relaxation testing machine fixture illustrating Fig. 1.
Specific embodiment
Describe the specific embodiment of relaxation testing machine fixture of the present utility model below in conjunction with accompanying drawing in detail.
Fig. 1 shows the sectional view according to relaxation testing machine fixture of the present utility model, for entering to fining twisted steel
Row relaxation test.
As shown in Figure 1, this relaxation testing machine fixture includes holder 1 and connector 2.Holder 1 company of being mounted to
In fitting 2.
Describe holder 1 and connector 2 below by way of Fig. 2 and Fig. 3 in detail.
As shown in Fig. 2 showing the sectional view of the holder 1 of the relaxation testing machine fixture shown in Fig. 1.
Holder 1 is cylindrical in shape shape on the whole and is in axial direction divided into two parts, and figure 2 illustrates this two
The one of part divided.
The outer surface 11 of holder 1 is in cone, and inner surface 12 is rounded.The inner surface 12 of holder 1 has with
, to fix fining twisted steel, fixed structure is along the longitudinal direction of holder for the fixed structure that the outer surface of fining twisted steel matches
Run through whole holder.
Specifically, in the holder 1 shown in Fig. 2, the fixed structure of holder 1 includes multiple chases 13 and is located at these
Contact site 14 between chase 13.Chase 13 can be matched with the screw thread on fining twisted steel, and contact site 14 can be with finish rolling
The main body of screw-thread steel contacts.The spacing of the screw thread on the width of the spacing between chase 14 and chase 13 and fining twisted steel
And the width of screw thread is corresponding, it is enable to stably keep fixed fining twisted steel.
Preferably, 5 to 9 sections of chases are provided with holder 1 altogether.It is highly preferred that being provided with 7 sections on holder 1 altogether
Chase.By such setting it is ensured that firmly fixing fining twisted steel sample.
Further, the surface of the contact site 14 of holder 1 is non-smooth surface, and for example, this non-smooth surface is by thin spiral shell
Line or annular knurl (in figure is all not shown) are formed.
The depth of chase 13 is more than or equal to the height of the screw thread on fining twisted steel, so more can firmly fix essence
Roll screw-thread steel and be easily installed.
Several spaced apart groove (not shown)s are provided with the outer surface 11 of holder 1, to reduce holder 1
CONTACT WITH FRICTION area and connector 2 between, thus using can be easily separated holder 1 and connector 2 after complete.
