Description

A kind of device for the test of component threadiness exit stretching-resisting bending-resisting
Technical field
This application involves component production technical fields, more particularly to one kind to be used for component threadiness exit stretching-resisting bending-resisting The device of test.
Background technique
Currently, in component production process, it usually needs exit strength test is carried out to it, to determine setting for exit Whether meter is resistant to the various mechanical stresses encountered in assembly, repairing or handling process with connection method.The survey of the prior art Method for testing is placed on product on one Simplified Test Equipment, which includes pedestal, support rod and set three parts of plate, each portion It point is connected by screw to together, component, which is placed in, when test sets on plate, and exit passes through the hole set on plate, carries out tension Test then hangs up counterweight on exit, by the regulation observation analysis of required standard;Tensile test is carried out then after hanging up counterweight, Rotation component body is bent the exit for hanging counterweight to about 90 degree manually, then by regulation observation analysis.Because common draw The exit of line element device has 2~16, and when carrying out beam test, rotating component main body manually will receive other exits Influence without easy to operate;The size of applied force is uneven when due to rotating main body manually, and the direction of power is also not completely the same, The angle of rotation is also not exclusively accurate, influences the accuracy of test result.So the test device of the prior art is carrying out bending resistance When test, there is not easy to operate, the problem of test result inaccuracy.
Summary of the invention
The application proposes a kind of device for the test of component threadiness exit stretching-resisting bending-resisting, it is intended to solve the prior art In the presence of not easy to operate, the problem of test result inaccuracy.
The application provides a kind of device for the test of component threadiness exit stretching-resisting bending-resisting, described to be used for component line The device of shape exit stretching-resisting bending-resisting test include lateral pedestal, longitudinal bracket, fixture, bearing, rocking bar, position fixing handle, Spring, limited block, fixing screws and attachment screw;Bracket is connected and fixed by fixing screws and pedestal;Fixture is pacified by bearing On bracket, and fixture is connect by attachment screw with rocking bar;Position fixing handle includes guide section, and spring pocket is in position fixing handle Outside, position fixing handle is mounted on rocking bar;Limited block is rack-mount, and is located at the top of rocking bar;It is provided on position fixing handle Positioning pin is provided with the matched location hole of the positioning pin on bracket.
Device for the test of component threadiness exit stretching-resisting bending-resisting of the invention, fixture are mounted on bracket by bearing On, so that fixture is rotated to the lead relative gravity direction of placed lead component on alignment jig inclination angle Degree;Plus after counterweight on lead, this inclined angle is exactly the curved angle of lead;Rocking bar passes through attachment screw and fixture Cooperation, the spinning movement of rocking bar is transmitted on fixture, and rocking bar and position fixing handle cooperate, and position fixing handle movement can drive rocking bar Movement, therefore the rotation of the movement controllable adjustable fixture by control position fixing handle;Spring control position fixing handle positioning pin with The cooperation of bracket, when the location hole in positioning pin alignment bracket, positioning pin is pressed into location hole, rocking bar is consolidated by spring stretching, extension It is fixed;By external force drawing position fixing handle, spring-compressed, positioning pin is extracted from location hole, and rocking bar is rotatable;Limited block can limit The rotational angle of rocking bar, since rocking bar can be fixed with fixture, so limited block can control the rotation angle of fixture;Fixing screws By it is simplest it is dismountable in a manner of rocking bar and fixture linked together, it is consistent with the rotational angle both guaranteed.The present invention The device for the test of component threadiness exit stretching-resisting bending-resisting, it is anti-that the traditional thread binding exit tension of component can either be carried out simultaneously Curved test, and exit can be made under the effect of gravity gradually by falling counterweight on lead, to the mode that fixture is rotated It bends, and accurately controls the bending angle of lead.
The application for component threadiness exit stretching-resisting bending-resisting test device, can reach it is following the utility model has the advantages that
The device for the test of component threadiness exit stretching-resisting bending-resisting of the application, is able to solve and is deposited in the prior art Not easy to operate, the problem of test result inaccuracy;The device is able to carry out tension and two kinds of bending resistance tests;Carrying out bending resistance It when test, can be controlled by position fixing handle, make the fixture rotation for placing component, and then make exit in the gravity of counterweight It bends under;Rotary location handle it is easy to operate, can save the operating time;Due to tested exit bending no longer by Good control can be obtained in the influence of other exits, the size and Orientation of bending force;It can accurately be controlled by limited block when test The bending angle of exit processed;The device can be improved test result accuracy, also can be improved component exit and is resisted Draw the working efficiency of beam test;It can be avoided inconvenient when multilead simultaneously, lead avoided to hurt hand, and avoid operation not The number of drawbacks such as sample loss at that time improve the accuracy of test result.
