Abstract
The utility model discloses a self-aligning joint device of a high temperature creep rupture strength tester. The self-aligning joint device comprises an outer joint, a steel ball, an inner joint and a joint clamping block, wherein one end of the inner joint is sleeved in the outer joint; the joint clamping block penetrates through the outer joint and is inserted in a transverse through hole of the inner joint; and the steel ball is arranged in the transverse through hole of the inner joint through tight fit, is clamped between the inner joint and the joint clamping block and does arc universal movement on the joint clamping block to realize a self-aligning effect. The utility model aims to provide the self-aligning joint device of the high temperature creep rupture strength tester, which has the advantages of simple structure and capability of realizing the self-aligning effect.
Description
Technical field
The utility model relates to a kind of piecing devices, particularly a kind of high-temerature creep permanent strength testing machine automatic aligning piecing devices that are used for testing various materials in the test of condition of high temperature stretched critical load.
Background technology
In the high-temerature creep permanent strength testing machine field; Testing machine will reach 1 grade test accuracy; Right alignment of the center line of piecing devices and sample jaw and afterburning axis requires and can not surpass 15% about it; And at present the high-temerature creep permanent strength testing machine is joined in the high temperature sample stretching coupling arrangement, the form of being threaded that all adopts that is connected of stainless steel pull bar and last lower sub.Make threaded hole at the center of last lower sub exactly, stainless pull bar directly twists into and realize to connect.This structure is when sample is installed, and the clamping difficulty can not realize automatic aligning, and test efficiency is low.
The utility model content
The purpose of the utility model provides a kind of simple in structure, can realize the high-temerature creep permanent strength testing machine automatic aligning piecing devices of automatic aligning effect.
For achieving the above object, the utility model adopts following technical scheme:
High-temerature creep permanent strength testing machine automatic aligning piecing devices; Comprise coupling, steel ball, nipple and joint fixture block, nipple one end is sleeved in the coupling; The joint fixture block passes coupling and is inserted in the cross through hole of nipple; The steel ball close-fitting pack in the cross through hole of nipple and holding between nipple and joint fixture block, steel ball is done the universal activity of circular arc on the joint fixture block, the effect of realization automatic aligning.
High-temerature creep permanent strength testing machine automatic aligning piecing devices as stated, it is characterized in that: said joint fixture block two ends put the fixture block sheath respectively.
The beneficial effect of the relative prior art of the utility model: nipple and joint fixture block in the utility model, said nipple one end is sleeved in the coupling, and the joint fixture block passes coupling and is inserted in the cross through hole of nipple; The steel ball close-fitting pack in the cross through hole of nipple and holding between nipple and joint fixture block; Steel ball is done the universal activity of circular arc on the joint fixture block, realize the automatic aligning effect, and is simple in structure; Convenient mounting and clamping can be enhanced productivity.
Description of drawings
Fig. 1 is the utility model neutral body synoptic diagram;
Fig. 2 is Fig. 1 inner structure cross-sectional schematic;
Fig. 3 is the synoptic diagram that two set of joints devices disassemble.
Embodiment
Understand understanding easily for technological means, creation characteristic, the purpose of reaching and effect that the utility model is realized, further set forth the utility model below in conjunction with accompanying drawing.
Like Fig. 1, Fig. 2 and shown in Figure 3,
High-temerature creep permanent strength testing machine automatic aligning piecing devices; Comprise coupling 1, steel ball 3; Nipple 4, joint fixture block 5 and fixture block sheath 6, nipple 4 one ends are sleeved in the coupling 1, and joint fixture block 5 passes coupling 1 and is inserted in the cross through hole 41 of nipple 4; Joint fixture block 5 two ends put fixture block sheath 6 respectively; Steel ball 3 close-fittings pack in the cross through hole 41 of nipple 4 and holding between nipple 4 and joint fixture block 5, steel ball 3 is done the universal activity of circular arc on joint fixture block 5, the effect of realization automatic aligning.In the utility model; Steel ball 3 realizes that close-fitting in the structure of nipple 4 and joint fixture block 5 is: on joint fixture block 5, establish a spherical groove; Establish the counterbore that faces spherical groove at cross through hole 41 towards a side of spherical groove; The card limit is between counterbore and spherical groove, and steel ball 3 can only be around the universal activity of its center circular arc to realize the automatic aligning effect like this.
During actual the use, adopt two piecing devices to cooperate two groups of pull bars to be connected with the sample two ends respectively again, piecing devices are directly installed on the testing machine; Two groups of pull bars and sample then can wholely be hung in upper and lower two piecing devices; Simple in structure, convenient mounting and clamping can be enhanced productivity.
