Abstract
The utility model discloses a tensile strength test fixture of a nylon sleeve. The tensile strength test fixture comprises a core rod, a fixed block and a cushion block, wherein the outer side of the core rod is provided with a thread matched with a thread in the nylon sleeve; the fixed block comprises a fixed block I and a fixed block II, and the fixed block I and the fixed block II are fixed and are fixed on the cushion block through bolts, and the fixed block I and the fixed block II are commonly provided with a thread hole matched with a thread arranged outside the nylon sleeve. The tensile strength test fixture provided by the utility model has the advantages that the original integral fixed block is divided into two pieces which are fixed through the bolts, after testing each time, the bolts are screwed out, the two fixed blocks are separated, and then the nylon sleeve is taken out, so that the cyclic utilization of the fixed block is realized, and the cost is consequently reduced.
Description
Technical field
The utility model relates to a kind of measurement jig, particularly a kind of tensile strength measurement jig of nylon sleeve.
Background technology
Concrete sleeper is one of railway main component, thereby adopt pre-buried nylon sleeve and bolt that fastener is installed in rail is installed above the sleeper.Train is in traveling process, and rail produces vibrations, and nylon sleeve is formed a pulling force that makes progress, and therefore, nylon sleeve need carry out the test of tensile strength to it before using.
Present measurement jig mainly is made up of fixed block and plug, be provided with the threaded hole that is complementary with the nylon sleeve external thread in the fixed block, the outside of plug is provided with the screw thread that is complementary with the nylon sleeve internal thread, during use, the nylon sleeve choosing is screwed in the threaded hole, again plug is screwed in the nylon sleeve, this tool is placed on the test machine tests at last.Nylon sleeve is damaged through regular meeting in the process of test, and nylon sleeve just is difficult to take out from fixed block so, causes scrapping of fixed block, can not be recycling, increased cost virtually.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of tensile strength measurement jig of nylon sleeve, and is recycling to realize fixed block, the purpose that reduces cost.
For achieving the above object, the technical solution of the utility model is as follows:
A kind of tensile strength measurement jig of nylon sleeve, comprise plug, fixed block and cushion block, the outside of described plug is provided with the screw thread that is complementary with described nylon sleeve internal thread, described fixed block comprises fixed block one and fixed block two, pass through bolt between described fixed block one and the fixed block two, and by being bolted on the described cushion block, be provided with the threaded hole that is complementary with described nylon sleeve external thread on described fixed block one and the fixed block two jointly.
Preferably, described plug is provided with fixed orifice one.
Preferably, the lower end of described cushion block is installed with coupling shaft, and described coupling shaft is provided with fixed orifice two holes.
Preferably, in described fixed orifice one and the fixed orifice two pin is set.
Pass through technique scheme, the tensile strength measurement jig of the nylon sleeve that the utility model provides, original unitary fixed piece is divided into two, and use bolt, the bolt of back-outing after each test is finished separates two fixed blocks, nylon sleeve can be taken out, realize the recycling of fixed block, reduced cost virtually.
Description of drawings
In order to be illustrated more clearly in the technical scheme among the utility model embodiment, the accompanying drawing of required use is done to introduce simply in will describing embodiment below.
Fig. 1 is the cut-open view of the tensile strength measurement jig of the disclosed a kind of nylon sleeve of the utility model embodiment.
Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described.
The utility model provides a kind of tensile strength measurement jig (referring to Fig. 1) of nylon sleeve, comprise plug 11, fixed block and cushion block 14, the outside of plug 11 is provided with the screw thread that is complementary with nylon sleeve 17 internal threads, fixed block comprises fixed block 1 and fixed block 2 13, pass through bolt between fixed block 1 and the fixed block 2 13, and by being bolted on the cushion block 14, be provided with the threaded hole that is complementary with nylon sleeve 17 external threads on fixed block 1 and the fixed block 2 13 jointly.
The utility model is divided into two with original unitary fixed piece, and use bolt, during use, nylon sleeve 17 choosings are screwed in the threaded hole, again plug 11 are screwed in the nylon sleeve 17, at last this tool is placed on the test machine and tests, the test bolt of back-outing after finishing separates two fixed blocks, nylon sleeve 17 can be taken out, realize the recycling of fixed block, reduced cost virtually.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and defined General Principle can realize under the situation that does not break away from spirit or scope of the present utility model in other embodiments herein.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the wideest scope consistent with principle disclosed herein and features of novelty.
