Description

technical field

[0001] The invention relates to a device in the technical field of automatic detection, in particular to a static load, stability and impact testing machine for chairs, cabinets, tables, beds, and screens used in furniture detection. Background technique

[0002] At present, similar detection devices have the disadvantages of low degree of automation, single or low integration of detection items, and lack of real-time tracking and storage functions for relevant parameters in the detection process. Existing equipment generally only uses cylinders for force loading, and cannot accurately control the telescopic displacement, loading force value, and load-holding time of the cylinder piston cylinder, etc., and does not have force tracking, feedback, and recording functions, and the cylinder under the action of air pressure The piston rod is prone to overshooting. Once the test piece is stuck, the equipment will continue to move, which will easily damage the test ...
