National standard wear resistance testing machine

Abstract

The invention relates to the technical field of shoe detection, in particular to a national standard wear resistance testing machine which comprises a shell, a driving device, a grinding wheel device and a balance device, the grinding wheel device comprises a control device and a grinding wheel body, a bottom plate is arranged at the bottom end of the shell, and the balance device comprises a controller, a balance body, a balancing weight, a supporting column, a distribution block, a shoe tree and a weight sensor. The driving device is electrically connected with the controller, a test insole is placed on a shoe tree, the control device can control the grinding wheel body to move in the X-axis direction, the Y-axis direction and the Z-axis direction so that the grinding wheel body can press the test insole, the driving device controls the position of the balancing weight and changes the size of a force arm on the right side of the balance, and therefore the balance weight of the balance is adjusted. The weight sensor detects the magnitude change of force and transmits the magnitude change to the controller, the driving device is adopted to control balance weight adjustment, the weight sensor is used for monitoring, and the balance weight adjustment mode is more accurate.

Description

technical field [0001] The invention relates to the technical field of shoe testing, in particular to a national standard wear-resistant testing machine. Background technique [0002] The wear resistance of the sole is an important indicator to measure the quality of shoes. In shoe production, it is necessary to test these properties of shoes. [0003] In the wear resistance test of the sole, one test requires the use of a grinding wheel to press vertically on the sample, and the wear test is carried out on the sample under specific conditions, and the length of the wear scar on the sample is measured to indicate the wear resistance of the sample. The configuration adjustment of the testing machine is relatively rough, and gravity is usually applied to the sole for wear-resistant testing, but the existing gravity is mostly applied manually, and there are errors in manual application, which affects the accuracy of the test data.

[0003] In the wear resistance test of the sole, one test requires the use of a grinding wheel to press vertically on the sample, and the wear test is carried out on the sample under specific conditions, and the length of the wear scar on the sample is measured to indicate the wear resistance of the sample, but currently on the market The configuration adjustment of the testing machine is relatively rough, and the shoe sole usually needs to be applied for wear resistance testing. However, the existing gravity is mostly applied manually, and there are errors in manual application, which affects the accuracy of the test data.
