Flexural rigidity tester for insole backpart

Abstract

The invention provides a flexural rigidity tester for an insole backpart. The flexural rigidity tester comprises a clamping mechanism used for clamping a hooked heart test piece, a force applying tool bit, a force value sensor, a digital dial gauge, a display operation screen, an upper limiting sensor, a lower limiting sensor, a servo driving motor, a left and right movement mechanism, a front and back movement mechanism, a dial indicator and a controller, wherein the force applying tool bit is connected with the servo driving motor through a screw nut transmission mechanism, the force value sensor and the digital dial gauge are arranged on the force applying tool bit, the servo driving motor is connected with the left and right movement mechanism and the front and back movement mechanism, and the left and right movement mechanism is connected with the dial indicator. The flexural rigidity tester for the insole backpart is wide in clamping width range, attractive in appearance, convenient to clean, smooth and reasonable in operation, and low in noise without a pulsation or vibration phenomenon; and the machine precision is high, test pieces are convenient to load and unload, and the position of a test process accords with the characteristics such as the vision of a human body and operation requirements, so that the test efficiency is greatly improved, and the working intensity of operators is alleviated.

Description

technical field [0001] The invention belongs to the field of shoe shank stiffness testing, and in particular relates to a shoe shank bending stiffness tester. Background technique [0002] The shank is a key part installed between the outsole and the inner midsole of leather shoes. It is the backbone of the shoe and plays a role in maintaining the curvature and stability of the sole. It is especially important for high-heeled shoes worn by women. Its quality determines its quality. The overall shape of the shoe is maintained and stable after wearing. The bending stiffness of the shank is a very important performance index of the shank. If the shank is not up to the standard, the overall deformation of the leather shoes will be caused, and the wearing will be unstable. In severe cases, it may even sprain and fall. However, the current shoe shank bending stiffness testers generally have problems such as complex structure, low precision, and inconvenient loading and unloading...

AI Technical Summary

Problems solved by technology

The bending stiffness of the shank is a very important performance index of the shank. If the shank is not up to the standard, the overall deformation of the leather shoes will be caused, and the wearing will be unstable. In severe cases, the feet may even sprain and fall.

However, the current shoe shank bending stiffness testers generally have problems such as complex structure, low precision, and inconvenient loading and unloading of samples.
