Static load, stability and impact testing machine for chairs, cabinets, tables, beds and screens

Abstract

The invention relates to a testing machine for chairs, cabinets, tables, beds and screens. The testing machine comprises a frame assembly, a plurality of moving crossbeam assemblies, moving vertical beam assemblies, horizontal electric cylinder assemblies and a control cabinet, wherein the moving crossbeam assemblies, the moving vertical beam assemblies and the horizontal electric cylinder assemblies are all connected with the frame assembly, and the control cabinet is connected with the moving crossbeam assemblies, the moving vertical beam assemblies and the horizontal electric cylinder assemblies. The testing matching integrates test items of furniture mechanical properties of chair, table and bed impact, cabinet, table and bed load, cabinet and table screen stability and the like, can be assembled and mounted optionally according to requirements, and is flexible to operate; integration level of equipment is increased greatly, a stepping motor and electric cylinders are introduced into the testing machine, a PLC (programmable logic controller) is used for control, automation level of the equipment is increased, accurate control of force loading and displacement is achieved, and the problems of single test item or low integration level, low automation level and inaccuracy of force loading and displacement control of existing furniture test equipment are solved.

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 ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to overcome the problems of the existing furniture detection equipment, such as single detection items or low integration, low automation level, inaccurate loading force value and displacement control, and provide a chair, cabinet, table, bed, screen, static load, stable Sex and impact testing machine, this testing machine integrates furniture mechanical performance testing items such as impact of chairs, tables and beds, static load of cabinets, tables and screens, stability of cabinets, tables and screens, etc. Improve the integration level of the equipment, the testing machine introduces stepper motor and electric cylinder, controlled by PLC, improves the automation level of the equipment, and realizes the precise control of force loading and displacement
