Abstract
The utility model relates to clamp art, specifically a kind of screw rod clamping positioning mechanism for extension test.A kind of screw rod clamping positioning mechanism for extension test, including screw body, it is characterised in that: the outer rim positioned at screw rod top is arranged with taper gripping sleeve, and the outer rim of taper gripping sleeve is arranged with sleeve；It is equipped with screw thread positioned at screw rod lower part, and screw rod lower part is connected through a screw thread stretching tool.Compared with the existing technology, a kind of screw rod clamping positioning mechanism for extension test is provided, pass through split type clamping positioning mechanism, the disc structure of screw rod upper end can be skipped, and direct clamping screw medium position, the pulled out condition that screw rod can be directly tested using existing tensile test device, realizes the purpose of screw rod extension test.
Description
Technical field
The utility model relates to clamp art, specifically a kind of screw rod for extension test clamps localization machine
Structure.
Background technique
Tradition has no idea to test for the tensile test of screw rod, and tested screw rod, structure are
There is a helicitic texture in upper end, and upper and lower ends have a disk connection, general fixture be have no idea it is straight across the disc structure of upper end
It connects and screw rod is clamped fixed, therefore, for the extension test of screw rod, there are certain difficulty, for screw rod product
Improvement on difficult, the demand for reaching client of having no idea.
Summary of the invention
The utility model in order to overcome the deficiencies of the prior art, provides a kind of screw rod clamping localization machine for extension test
Structure can skip the disc structure of screw rod upper end by split type clamping positioning mechanism, and position directly in clamping screw
It sets, the pulled out condition of screw rod can be directly tested using existing tensile test device, realizes the purpose of screw rod extension test.
To achieve the above object, a kind of screw rod clamping positioning mechanism for extension test, including screw body are designed,
It is characterized in that: being arranged with taper gripping sleeve positioned at the outer rim on screw rod top, the outer rim of taper gripping sleeve is arranged with sleeve；Positioned at spiral shell
Bar lower part is equipped with screw thread, and screw rod lower part is connected through a screw thread stretching tool.
The taper gripping sleeve is inverted pyramidal structures wide at the top and narrow at the bottom, and taper gripping sleeve is by left gripping sleeve and right gripping sleeve
Composition.
The left gripping sleeve and right gripping sleeve are half inverted pyramidal structures wide at the top and narrow at the bottom.
The sleeve is collar plate shape structure, and sleeve center is equipped with back taper through-hole.
The size of back taper through-hole on the inside of the sleeve matches with taper gripping sleeve shape size.
The utility model compared with the existing technology, provides a kind of screw rod clamping positioning mechanism for extension test, passes through
Split type clamping positioning mechanism, can skip the disc structure of screw rod upper end, and directly clamping screw medium position, Neng Gouli
The pulled out condition that screw rod is directly tested with existing tensile test device, realizes the purpose of screw rod extension test.
Detailed description of the invention
FIG. 1 is a schematic structural view of the utility model.
Fig. 2 is the utility model structure top view.
Fig. 3 is tapered clamp tight tube structure schematic diagram.
Fig. 4 is tube-in-tube structure schematic diagram.
It is screw rod referring to Fig. 1, Fig. 2,1,2 be stretching tool, and 3 be taper gripping sleeve, and 3-1 is left gripping sleeve, and 3-2 is right folder
Fixed, 4 be sleeve.
Specific embodiment
The utility model is described further below according to attached drawing.
As shown in Figures 1 to 4, the outer rim positioned at 1 top of screw rod is arranged with taper gripping sleeve 3, the outer rim of taper gripping sleeve 3
It is arranged with sleeve 4；It is equipped with screw thread positioned at 1 lower part of screw rod, and 1 lower part of screw rod is connected through a screw thread stretching tool 2.
Taper gripping sleeve 3 is inverted pyramidal structures wide at the top and narrow at the bottom, and taper gripping sleeve 3 is by left gripping sleeve 3-1 and right gripping sleeve
3-2 composition.
Left gripping sleeve 3-1 and right gripping sleeve 3-2 is half inverted pyramidal structures wide at the top and narrow at the bottom.
Sleeve 4 is collar plate shape structure, and 4 center of sleeve is equipped with back taper through-hole.
The size of the back taper through-hole of 4 inside of sleeve matches with 3 shape size of taper gripping sleeve.
As shown in Figure 1, there is screw thread in the lower end of tested screw rod 1, the lower end of screw rod 1 is connected through a screw thread stretching tool 2, spiral shell
The top outer rim of bar 1 is arranged with taper gripping sleeve 3 and is clamped fixation, and sleeve 4 is set in the outside of taper gripping sleeve 3, is used to
Fixed tapered clamp fixed 3, prevents left gripping sleeve 3-1 and right gripping sleeve 3-2 from giving away, the size of the back taper through-hole of 4 inside of sleeve
Match with 3 shape size of taper gripping sleeve, in this way, sleeve 4 can firmly entangle taper gripping sleeve 3, can preferably clamp
Screw rod 1, when doing extension test, 1 lower end of screw rod is connect with tooling 2 is stretched, the upper end of cupping machine directly clamp sleeve 4 and to
On stretched, the case where screw rod 1 is stretched can be observed in drawing process, data directly display drafting results, simple, side
Just, it directly takes test data convenient for operator, and screw rod is improved.
