Abstract
The utility model provides a tensioning ring tensile testing tooling, which comprises connecting seats, stressed pins and sleeves. Each connecting seat includes a clamping rod and an 'n'-shaped connecting portion connected to the rear end of the clamping rod, each connecting portion includes two lateral walls, and through holes are arranged on both of the two lateral walls of each connecting portion. The clamping rods of the connecting seats are clamped in jaws of tensile machines, each sleeve is positioned between the two through holes of the corresponding connecting portion, each stressed pin penetrates through a through hole formed by communicating the two through holes of the lateral walls of the corresponding connecting portion with a through hole of the corresponding sleeve, and a tensioning ring is sleeved on the peripheries of the sleeves. The tensioning ring tensile testing tooling performs a tensile force test on assessing points of a test object completely according to working conditions of the tensile ring, verifies whether the performance of a product can meet technical requirements or not, and accordingly improves reliability of the product.
Description
Technical field
The utility model relates to a kind of test frock, particularly relates to a kind of tensioning ring tension test frock.
Background technology
ETT direct-current transmission converter valve thyristor assembly adopts standardized designs, and each thyristor assembly is piled into by the thyristor of six series connection, and each thyristor is between two aluminium radiators.Thyristor/heat sink stack is applied the pressure of 135kN to guarantee good electrical contact and thermo-contact by two tensioning rings.So, also do not have now a kind of can real simulation tensioning ring operating mode under the frock of actual loading situation come tensioning ring is carried out tension test, whether satisfy technical requirement with the checking properties of product, thereby improve reliability of products.
The utility model content
The purpose of this utility model provides a kind of tensioning ring tension test frock, the force-bearing situation under the feasible simulation pulling force ring operating mode.
To achieve these goals, the utility model adopts following technical scheme:
A kind of tensioning ring tension test frock is made up of Connection Block, stressed pin and sleeve pipe three parts; Described Connection Block comprises supporting rod and the connecting portion that is connected in the supporting rod rear end, and connecting portion is " door " shape, and this connecting portion comprises two sidewalls, all offers through hole on the sidewall; The supporting rod of Connection Block is held in the jaw of puller system, and sleeve pipe is between two through holes, and described stressed pin passes two through holes of sidewall of connecting portion and the through hole of sleeve pipe connects the through hole that forms, and tensioning ring is placed in described sleeve pipe periphery.
The material of described stressed pin is the 40Cr steel.
Compared with prior art, a kind of tensioning ring tension test of the utility model frock is carried out tensile test according to the force way under the tensioning ring operating mode to test product examination point fully, and whether the performance of checking product can reach technical requirement, thereby improves reliability of products.

Embodiment
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail.
See also Fig. 1 to shown in Figure 4, a kind of tensioning ring tension test of the utility model frock is made up of Connection Block 1, stressed pin 2 and sleeve pipe 3 three parts; Connection Block 1 comprises supporting rod 11 and is connected in the connecting portion 12 of supporting rod 11 rear ends, the supporting rod chambers of experimentizing 11 are held in the jaw of puller system, connecting portion 12 is " door " shape, and this connecting portion 12 comprises two sidewalls 121, offers through hole 120 on the sidewall 121.Its design feature of a kind of tensioning ring tension test of the utility model frock: at first this frock is examined test product according to the force way under tensioning ring 4 operating modes fully, secondly with the selected 40Cr steel of the material of stressed pin 2, and require the hardness after the thermal treatment to reach HB270-350, in addition, when guaranteeing stressed pin 2 stress-bearing capability, according to operating mode size design Connection Block 1, stressed pin 2, sleeve pipe 3, tensioning ring 4 fit dimensions, guaranteed that the test product tensioning ring is according to work condition state work in test is carried out.
Test procedure:
1, the installation of Connection Block 1: a pair of Connection Block 1 is installed on respectively in the two ends jaw of testing machine, the usage level instrument guarantees that the installation of Connection Block is parallel to each other, and avoids process of the test to occur reversing;
2, the installation of test product tensioning ring 4: tensioning ring 4 is positioned in the Connection Block 1, sleeve pipe 3 is positioned between two through holes 120 on the Connection Block 1, stressed pin 2 is passed through hole in through hole 120 and the sleeve pipe 3, utilize Connection Block 1, stressed pin 2 and sleeve pipe 3 that tensioning ring 4 is fixing, and guarantee that tensioning ring 4 installation back end positions are parallel;
3, service-test machine applies suitable pulling force and tests.
The utility model tensioning ring tensile strength test special tooling carries out tensile test according to the force way under the tensioning ring operating mode to test product examination point fully, and whether the performance of checking product can reach technical requirement, thereby improves reliability of products.
Although in conjunction with the accompanying drawings the preferred embodiment of the utility model technology is described above; but the utility model technology is not limited to above-mentioned embodiment; above-mentioned embodiment only is schematic; rather than it is restrictive; those of ordinary skill in the art is under the enlightenment of the utility model technology; do not breaking away under the scope situation that the utility model technical purpose and claim protect; can also make a lot of forms, these all belong within the protection of the utility model technology.
