Abstract
The utility model discloses a stretching load-holding test fixture with high generality and convenience in usage to identify the loading property of a nut. The stretching load-holding test fixture comprises upper tools, lower tools and a clamp splice. The stretching load-holding test fixture is characterized in that the upper tools and the lower tools have the same structure and both possess a frame with a notch. One side of the frame away from the notch is connected with a fixing part and the fixing part is provided with a first through hole. A stop dog with a contour larger than the notch is arranged on the clamp splice. A containing cavity to hold the nut for test is arranged in the middle of the stop dog. A second through hole with a contour smaller than the contour of the nut for test is placed in the containing cavity. The stretching load-holding test fixture is simple in structure, convenient to use and high in generality. The stretching load-holding test fixture can conduct stretching load-holding test on nuts and bolts with various sizes and can effectively improve working efficiency.
Description
Technical field
The utility model belongs to the mechanical designing technique field, particularly relates to a kind of stretching and protects a year test fixture.
Background technology
In Machine Design, it is very important pilot project that nut is protected a year test, at present nut is protected and is carried that test is general directly to be tested with the bolt tension anchor clamps, be the disclosed ordinary bolt of patent, the nut test clamp of CN200720171597.1 such as the patent No., formed by upper fixture block, lower fixture block, test screw rod (the test nut is protected and carried special use) etc., upper fixture block, lower fixture block adapt to the upper and lower jaw seat shape of universal testing machine, and adopt thread connection test bolt or test nut.Upper fixture block, lower fixture block are installed in respectively on the upper and lower jaw seat of universal testing machine.Upper fixture block, lower fixture block directly cooperate connection with bit, need not change the Wedge gripping testing table, just can realize the exchange of general tensile test and bolt strength test.But the size of the upper fixture block of bolt tension anchor clamps, lower fixture block is larger, so the jaw size of universal testing machine defines the specification requirement that the nut guarantor is carried test.
Summary of the invention
The purpose of this utility model is that a year test fixture is protected in a kind of highly versatile of proposition, stretching easy to use, to be used for the load performance of checking nut.
Stretching of the present utility model is protected a year test fixture and is comprised frock, lower frock, fixture block, key is that the structure of described upper frock, lower frock is identical, all have one and be with framework jaggy, described framework is connected with a fixed part away from a side of breach, and described fixed part is provided with the first through hole; Described fixture block is provided with profile greater than the block of described breach, and the middle part of described block is provided be used to the accommodating cavity that holds nut to be measured, and described accommodating cavity is provided with profile less than the second through hole of nut profiles to be measured.
When test, at first nut to be measured is put into the accommodating cavity of fixture block, again block is put into the framework of upper frock (lower frock), and a test bolt is passed from inside to outside the breach of lower frock (upper frock) framework, and pass the second through hole and screw in nut to be measured, utilize at last the first through hole of upper frock, lower frock that upper frock, lower frock and the upper and lower jaw seat of universal testing machine are fixed, can carry out tension test to nut to be measured, test its load performance.Because upper frock, lower frock are to fix by the first through hole and jaw seat, rather than directly snap in the jaw seat, therefore no longer be subjected to the restriction of jaw seat volume, strengthened versatility.
Further, described the second through hole is provided with internal thread, utilizes like this fixture block just can realize load test to bolt, as long as bolt to be measured is passed from inside to outside the breach of lower frock (upper frock) framework, and the second through hole of screw-in fixture block, just can carry out tension test.
Further, described block is provided with teat near an end of the second through hole, and the internal diameter of the external diameter of described teat and described the first through hole matches, and when test, teat snaps in the first through hole, can prevent that anchor clamps from rocking.
Further, described framework is provided with connecting hole away from a side of breach, and described fixed part passes connecting hole, and the end of described fixed part is provided with profile greater than the anti-delinking part of described connecting hole.Fixed part just can rotate relative to framework like this, the installation of convenient nut to be measured (bolt).
Stretching of the present utility model is protected and is carried simple in structure, easy to use, the highly versatile of test fixture, can stretch to the nuts and bolt of all size to protect to carry test, but the Effective Raise work efficiency.

Embodiment
The below contrasts accompanying drawing, by the description to embodiment, the effect of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and principle of work etc. are described in further detail.
Embodiment 1:
Shown in Fig. 1,2,4, the stretching of present embodiment is protected a year test fixture and is comprised frock, lower frock, fixture block 3, the structure of upper frock, lower frock is identical, all has one with jagged 11 framework 12, framework 12 is connected with a fixed part 13 away from a side of breach, and fixed part 13 is provided with the first through hole 14; Framework 12 is provided with connecting hole 15 away from a side of breach 11, and fixed part 13 passes connecting hole 15, and the end of fixed part 13 is provided with profile greater than the anti-delinking part 16 of described connecting hole 15.
Fixture block 3 is provided with profile greater than the block 31 of described breach 11, and the middle part of block 31 is provided be used to the accommodating cavity 32 that holds nut 4 to be measured, and accommodating cavity 32 is provided with profile less than the second through hole 33 of nut 4 profiles to be measured; Block 31 is provided with teat 34 near an end of the second through hole 33, and the internal diameter of the external diameter of teat 34 and described the first through hole 14 matches.
