Description
Technical field
The present invention relates to detection fields, and in particular to a kind of furniture door hinge durability automatic checkout system.
Background technique
The detection of furniture door hinge is the relevant criterion of foundation country to judge the qualified or not main means of properties of product, door
Cutting with scissors endurance quality test is the important detection project of one of them.When carrying out the detection of door hinge endurance quality, fixed cabinet body or cabinet
Side plate, door-plate are installed on cabinet body or side cabinet by door hinge, and appropriate load is added on door-plate, then in door handle or
The specified point of application carries out push-and-pull switch by the frequency and angle end of door plate of setting, stops surveying after reaching the actuation cycle number of setting
Whether examination, inspection and evaluation door hinge product have quality damage.
Wherein, in the switching process of door-plate, being unable to end of door plate has too big lateral force (power along door-plate direction), otherwise
There can be very big adverse effect to door hinge.In addition, needing the position to work in its function to stop if door hinge is with pooling feature is closed
Only end of door plate exerts a force, allow the buffer unit of door hinge in each circulation can free-running operation, in order to avoid external force fills the buffering of door hinge
It sets and has an adverse effect.
For testing requirements described above, conventional door hinge durability tester is difficult to meet test strip under normal circumstances
Part.Routine test machine is all linear running for pulling the biography bar of door-plate, and the switch motion (circular arc) with door-plate is misfitted,
Biggish lateral force, the problem for bringing test result not accurate can be added to door hinge during push-and-pull.And test machine and door
The connection of plate is usually the pooling feature realized when door-plate is closed with rope system handle or the point of application, the frictional force meeting of rope
Influence the full action of pooling feature.
