Scissor performance testing device

Abstract

The invention discloses a scissor performance testing device. The device comprises a supporting body; the supporting body is provided with a first sliding rail, a movable assembly slidingly arranged on the first sliding rail, a first transmission mechanism for driving the movable assembly to slide on the first sliding rail, and a fixed assembly fixed onto the first sliding rail, wherein the movable assembly is provided with a pressure sensor; the device further comprises a control processor; the pressure signal output terminal of the pressure sensor is connected with the first signal input terminal of the control processor; and the first signal output terminal of the control processor is connected with the control signal input terminal of the first transmission mechanism. During a test, the movable assembly slides relative to the fixed assembly so as to drive tested scissors to be opened and closed; pressing forces required during the opening and closing process of the scissors are quantified; and the distribution condition of the required forces during the use process of the tested scissors when the tested scissors are in different opening and closing degrees can be obtained through analysis, and therefore, the performance of the tested scissors can be evaluated effectively.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a scissors performance testing device. Background technique [0002] In production and life, scissors with double blades are widely used. In order to meet the use requirements of scissors and achieve the specified use effect of scissors, scissors manufacturers at home and abroad need to test the performance of scissors after the scissors are produced. Test the fatigue strength, test the labor-saving effect of scissors, etc. [0003] However, in the prior art, there is still a lack of devices that can automatically, efficiently and accurately perform scissor performance testing. Most of the workload in the scissor performance testing process of most scissor manufacturers needs to be completed manually, which takes up a considerable amount of time. manpower, the test efficiency is very low and the test results are not accurate.
