Description
Technical field
The utility model relates to a kind of frock of test specimen tension test, relates in particular to a kind of special tooling that securing member is carried out tension test.
Background technology
Along with securing member being widely used at aerospace field, mechanical property to securing member requires also more and more higher, " pulling strengrth " as an important indicator of securing member mechanical property, can test out by tension test pulling strengrth, yield strength of securing member etc.; But because tension test belongs to destructive test, tested testpieces is being broken when destroying, and can produce the reacting force after the destruction, and when product specification was larger, the destruction reacting force of generation is also larger.The destruction reacting force that test produces can together splash out together with test tool with tested testpieces, and this is to the security presence hidden danger of testing crew, and so not only safety coefficient is low, and the accuracy of measurement result also is restricted.
Summary of the invention
Problem to be solved in the utility model provides a kind of special tooling of safe and reliable, the high securing member tension test of test detection accuracy.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of securing member tension test special tooling, this frock is symmetrical structure up and down, comprise connecting link, clamping ring, the test cover, protective cover, described clamping ring is provided with external thread, test puts and is provided with open slot and internal thread, the external thread of clamping ring is connected with the screw-internal thread fit of test cover, clamping ring is sleeved on the connecting link, protective cover is sleeved on test and puts, the utility model also comprises set collar, Compress Spring, center, described clamping ring upper surface has a cylindrical hole, center, clamping ring lower surface has a segment shape cavity, and cylindrical hole and segment shape cavity connect, and the centre of sphere of segment shape cavity drops on the central axis of cylindrical hole; The top of described connecting link is cylinder, and its underpart is a segment, and the centre of sphere of segment drops on the central axis of cylinder; The side of described protective cover is provided with threaded hole, and the threaded hole coupling has taper bolt; Described set collar and connecting link are interference fit; Compress Spring is installed between set collar and the clamping ring.
Further, the side of described connecting link also is provided with a threaded hole.
Further, the side of described set collar is provided with a through hole.
Further, the threaded hole on the described connecting link and the through hole on the set collar are complementary, and threaded hole mates a holding screw.
Further, the segment shape cavity of described clamping ring just in time can hold the segment of connecting link.
Further, also comprise the lower frock of the upper frock of test and test, the central axis place of frock has the cavity of laying the test specimen head in the described test, and the central axis place of frock has an internal thread hole that is complementary with the external thread of test specimen bar section under the described test.
Advantage and the good effect that the utlity model has are: because the setting of protective cover is wrapped up test specimen completely, avoided test specimen to fly out during test and injured testing crew by a crashing object; The setting of Compress Spring makes the destruction reacting force obtain effective buffering, has protected whole frock, has prolonged the serviceable life of frock; The setting of segment on the connecting link makes energy automatic capturing between test specimen and the frock, has improved the accuracy that test detects; That this frock has simultaneously is simple in structure, handled easily, advantage that cost is low.

Embodiment
Below in conjunction with accompanying drawing the utility model is further elaborated.
As shown in Figure 1, the utility model is a kind of special tooling that securing member is carried out tension test.This frock is symmetrical structure up and down, comprise connecting link 1, clamping ring 3, test cover 4, protective cover 8, set collar 5, Compress Spring 6, the upper frock 9 of test, test under frock 11 and test specimen 10; Clamping ring 3 is provided with external thread; Test cover 4 is provided with open slot and internal thread; Have a circular hole and a segment shape cavity on the central axis of clamping ring 3, circular hole and segment shape cavity connect, and the centre of sphere of segment shape cavity drops on the central axis of cylindrical hole; The top of connecting link 1 is cylinder, and its underpart is a segment, and the centre of sphere of segment drops on the central axis of cylinder; The side of protective cover 8 is provided with threaded hole, and the threaded hole coupling has taper bolt 7; The central axis place of frock 9 has the cavity of laying the test specimen head in the test, and the central axis place of the lower frock 11 of test has an internal thread hole that is complementary with the external thread of test specimen bar section; Set collar 5 is interference fit with connecting link 1, and Compress Spring 6 is installed between set collar 5 and the clamping ring 3, and clamping ring 3 is sleeved on the connecting link 1, and clamping ring 3 is threaded with test cover 4, and protective cover 8 is sleeved on the test cover 4; In the test frock 9 be connected down frock 11 and connect by test specimen 10; In the open slot that the test that frock 9 and test descend frock 11 to be stuck in respectively the upper and lower symmetry of this special tooling in the test is overlapped, so just upper and lower two parts of this special tooling are connected together, at this moment just can have carried out tension test to test specimen.
In the present embodiment; when test specimen 10 is carried out tension test; the experimenter rotates to an angle protective cover 8; protective cover 8 is blocked open slot; at this moment the die cavity of whole tension test special tooling just is in the complete closed state, and namely whole test specimen is wrapped in the protective cover 8, has avoided test specimen because outside the die cavity of the frock that flies out after destroyed in the process of the test; so that injure testing crew by a crashing object, avoided the generation of security incident.
In the present embodiment, the effect of set collar 5 is that Compress Spring 6 is forced down, and makes Compress Spring 6 become impaction state by free state under normal circumstances.During test; if test specimen 10 is destroyed; then can produce one and destroy reacting force, at this moment, the flexible of Compress Spring 6 will absorption portion destroy reacting force; play the effect of buffering; the destructive power of destroying reacting force is alleviated, reduced the impact of this destructive power to stretch sensor, simultaneously; whole frock is effectively protected, has greatly improved the serviceable life of whole frock.
In the present embodiment, the cylindrical side of connecting link 1 is provided with a threaded hole, the side of set collar 5 be provided with one with connecting link 1 be the through hole that threaded hole is complementary, one holding screw 2 is installed in this threaded hole or the through hole, the setting of this holding screw, make set collar 5 firm being installed on the connecting link 1, avoid producing because of the rebound effect of compression bolt 6 and endwisely slip.
In the present embodiment, the mode of being connected between the segment of the segment shape cavity of clamping ring 3 and connecting link 1 clamping ring is equivalent to Universal connector hair style connected mode, this connected mode is in process of the test, the automatic capturing that is connected between test specimen and this special tooling can be realized, the accuracy of test testing result will be greatly improved like this.
In sum, the utility model is safe and reliable, long service life, testing result accuracy high, has simultaneously simple in structure, handled easily, advantage that cost is low.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
