Abstract

The utility model discloses a connecting structure of a round sample stretching test device, which comprises a sample stretching device bolt, a sample stretching device hanging module, panels, testing machine clips and connecting bolts. The sample stretching device bolt is in threaded connection with thread holes in the panels. The panels are connected with the testing machine clips by the connecting bolts. The sample stretching device hanging module is divided into two symmetrical parts for clamping a round sample. The numbers of the panels, the clips and the connecting bolts are 2 to 4. Based on utilization of the original testing device of a testing machine, the utility model designs and manufactures the connecting structure of the round sample stretching test device, which is convenient to assemble and disassemble. A round sample stretching clamp can be arranged without disassembling the testing machine clips so as to save manpower resources, material resources and time.

Description

Circular specimen tensile test apparatus syndeton
Technical field
The invention belongs to the material test technology, relate to test design of Clamping Apparatus and improvement in the metal material stretching test.
Background technology
For the tensile property test of metal material, the equipment that uses is electronic tension tester at present.Usually when purchasing testing machine, be equipped with all anchor clamps that can use, spare part on the cupping machine complete.The problem of bringing is when carrying out different tests, needs to change anchor clamps, and the operator of work brings certain trouble to every day.The circular specimen tensile test apparatus of existing cupping machine, connected mode is all identical with the testing machine chuck, promptly when using the circular specimen tensile test apparatus, needs with behind the test chuck removal circular specimen tensile test apparatus to be fixed on the testing machine.When the tension test machine grip holder is heavier, change the circular specimen stretching clamp as lower chuck on the need removal, must outfit can lifting little fork truck, operation inconvenience, inefficiency.
Summary of the invention
The purpose of this utility model is: on the basis that utilizes the original test unit of testing machine, manufacture and design the circular specimen tensile test apparatus syndeton of conveniently assemble and disassemble, be beneficial to the operator and change test unit quickly and easily.
The technical solution of the utility model is: design a kind of circular specimen tensile test apparatus syndeton, comprise sample stretching device bolt 1, sample stretching device suspension module 2, flat board 3, testing machine chuck 4, coupling bolt 5, it is characterized in that the threaded hole in sample stretching device bolt and the flat board is spirally connected; Flat board is connected with the testing machine chuck by coupling bolt.
Described sample stretching device suspension module is a two parts symmetrical, in order to clamp circular specimen.
Described flat board and chuck coupling bolt are 2~4.
The utility model has the advantages that: need not to dismantle the testing machine chuck, the circular specimen stretching clamp can be installed, save human and material resources and time, save the expense of purchasing this device simultaneously.
Description of drawings
Fig. 1 improves the circular tensile sample test unit structural representation in back.
Embodiment
Below the utility model is described in further details.
Circular specimen stretching device and testing machine connected mode have the locked connection collar for being threaded before improving, need be with testing machine chuck removal, and then with the precession of circular specimen stretching device, dead with locked adapter sleeve ring lock.
Circular specimen stretching device synoptic diagram after the improvement is seen Fig. 1.
As Fig. 1, sample stretching device syndeton after the improvement be directly on the testing machine chuck with four screw retention on centre be threaded the flat board of the 150*100*50 in hole, to improve the threaded hole in the back circular specimen stretching device bolt precession flat board then, be fixed on the testing machine chuck.
Under the situation of not dismantling the testing machine chuck, when circular tensile sample adopted the suspension type test, test space will have enough height behind the sectional fixture, through measuring, testing machine up and down between two chucks distance should 〉=420mm.
