Pressure applying mechanism for plate quality detection

Abstract

The invention discloses a pressure applying mechanism for plate quality detection in the technical field of plate detection. The mechanism comprises a gravity pressure applying mechanism, a pressure bearing seat mechanism and a take-up and pay-off mechanism, wherein the pressure bearing seat mechanism is mounted in the center of the top of a supporting seat, the gravity pressure applying mechanismis arranged right above the pressure bearing seat mechanism, and the gravity pressure applying mechanism is connected with the take-up and pay-off structure through a pull rope. The mechanism is advantaged in that plates with different sizes and thicknesses can be rapidly loaded, movement gravity pressure application is completed through the arrangement of the gravity pressure applying mechanism,the pressure bearing seat mechanism and the take-up and pay-off mechanism, multiple times of weight adjustment are conducted to calculate different stress sizes and mass states, a pressure applying block freely falls downwards to conduct smashing force application on a detected plate, the detected plate is accurately aligned with the stress center of the plate, and rapid plate hardness detectioncan be conducted.

Description

technical field [0001] The invention relates to the technical field of plate detection, in particular to a pressure applying mechanism for plate quality detection. Background technique [0002] Comparing the soft and hard indexes of various materials stipulates different test methods, and also has different hardness standards, which can be compared through experiments. [0003] At present, for the hardness test of the plate, the hardness is usually measured by the indentation method (Brinell, Rockwell, Vickers). The hardness value indicates the ability of the material surface to resist the plastic deformation caused by the intrusion of another object. The indentation distance is related to the indentation area, and the indoor temperature also has a certain influence on the experimental results. In the current plate hardness test, the measurement of the indentation distance requires manual inspection, and the error is large. [0004] In different application fields, the requ...

[0003] At present, for the hardness test of the plate, the hardness is usually measured by the indentation method (Brinell, Rockwell, Vickers). The hardness value indicates the ability of the material surface to resist the plastic deformation caused by the intrusion of another object. The indentation distance is related to the indentation area, and the indoor temperature also has a certain influence on the experimental results. The current plate hardness test requires manual inspection for the measurement of the indentation distance, and the error is large.

[0004] In different application fields, the requirements for the hardness of the plate are different. When testing the hardness of the plate, the impact test is usually used. The process of the impact test is unstable, and data errors are prone to occur, resulting in deviations in the test results. And height adjustment equipment, most of the existing equipment for hardness quality testing of plates takes a long time to do work such as adjusting weight, height measurement, and plate fixing in the early stage, which is troublesome to operate
