Description
Technical field：
It the utility model is related to a kind of mechanical stretch test fixture.
Background technology：
Mechanical stretch experiment is the experiment for being tested the various mechanical properties of metal works, and it can measure metal
The mechanical index such as the elastic limit of workpiece, yield point, tensile strength, elongation, the contraction percentage of area, are studied in depth to instruction of papil
Mechanical knowledge is significant, easily falls off phenomenon during the stationary fixture clamp assay part of existing cupping machine, causes
The failure of an experiment, or even jeopardize the personal safety of testing crew, test can make the inclination of testpieces generation to be detected somewhat, pulling force
There is deviation in test effect, influences measuring accuracy, every kind of test block can only use a kind of test fixture, and fixture can not be general.
Utility model content：
The purpose of this utility model is to provide a kind of mechanical stretch test fixture.
Above-mentioned purpose is realized by following technical scheme：
A kind of mechanical stretch test fixture, its composition include：Jig frame, the upper end of described jig frame, which is provided with, to be carried
Hand, described jig frame inside set two clamping plates, and each described clamping plate is fixedly connected with two fixing pipes, and described consolidates
Fixed tube is placed in the circular hole of described jig frame side, and threaded screw rod is threadedly coupled with the clamping plate described in two respectively, described
The both ends of threaded screw rod be connected respectively with described jig frame by bearing, the left end of described threaded screw rod, which is provided with, to be shaken
Arm, has groove on described clamping plate, and chuck is placed in described groove.
Described mechanical stretch test fixture, described clamping plate are in circular arc, and the clamping plate described in two is arranged vertically, described
Chuck be provided with anti-slip veins.
Beneficial effect：
1. operation principle of the present utility model is：Rocking arm is rotated, threaded screw rod rotates, two clamping plates as rocking arm rotates
Will be mobile to centre, longer testpieces is placed in two clamping plates, is rotated further rocking arm so that two clamping plates are by testpieces
Clamping, when testpieces is shorter, testpieces can be clipped between two chucks and be tested.
The utility model uses two chucks, and chuck can be changed at any time, according to the shape and size of testpieces
Different chucks is changed, a fixture can be tested different testpieces, very convenient.
There are anti-slip veins on chuck of the present utility model, can prevent that testpieces comes off and tilted during testing in fact
Phenomenon.
Between longer testpieces is placed on two clamping plates by the utility model, it can be tested, two clamping plates are in
Circular arc, the destruction to the surface of testpieces can be prevented, testpieces is played a protective role.
The utility model realizes the movement between two clamping plates using the structure of threaded screw rod, and mobile is more steady, tries
It is more laborsaving to test personnel.
The each clamping plate of the utility model and two fixing pipe connections, during can preventing that clamping plate from moving and accommodating again
There is the phenomenon offset.
Brief description of the drawings：
Accompanying drawing 1 is structural representation of the present utility model.
Accompanying drawing 2 is the structural representation of clamping plate of the present utility model.
