Full-automatic control chair seat impact resistance test device and test method

Abstract

The invention discloses a full-automatic control chair seat impact resistance test device which comprises a bottom plate, a support bracket, a hammering mechanism and a control cabinet, wherein the control cabinet is used for controlling the hammering mechanism to act; the support bracket comprises two stand columns and a support cross beam which is arranged at the tops of the two stand columns; a plurality of chain wheels are arranged on the lower side of the support cross beam; the hammering mechanism comprises a hammering air cylinder, a balancing weight and a hammering chain; the direction of a piston rod of the hammering air cylinder is upward; one end of the hammering chain is connected with the piston rod of the hammering air cylinder and the other end of the hammering chain bypasses the chain wheels to be connected with the balancing weight; a chair fixing position is arranged on the bottom plate; the position of the chair fixing position corresponds to the position of the balancing weight; a PLC is arranged in the control cabinet; an operation panel is arranged at the top of the control cabinet; the PLC is electrically connected with the hammering air cylinder through an electromagnetic valve. The full-automatic control chair seat impact resistance test device and test method are high in stability in test process and accurate and reliable in test result, and can be used for randomly adjusting the hammering force to be suitable for different models of chairs.

Description

technical field [0001] The invention belongs to the field of chair quality detection, and in particular relates to a fully automatic control chair seat impact resistance test device and a test method thereof. Background technique [0002] During the normal use of the seat, the seat of the chair will be subjected to cumulative load and impact force, so a safe and reliable seat must be able to withstand a certain amount of impact. [0003] However, existing seat manufacturers generally lack special test equipment for the impact resistance of seat backs, and usually use temporary test equipment for testing. This kind of temporary test equipment is generally relatively simple, so that stability and Accuracy is not guaranteed, and applicable chair models are also limited. Contents of the invention [0004] In order to solve the defects and deficiencies in the above-mentioned prior art, the present invention provides a fully automatic control chair seat impact resistance test d...
