Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0022] refer to Figure 1 to Figure 4 , The piezoelectric full-angle load detection device includes an outer wall 1 , a honeycomb structure 2 , a middle wall 3 , a triangular structure 4 , an inner wall 5 and a piezoelectric sheet 6 .

[0023] The outer wall 1 is a cylindrical part made of steel. The height of the outer wall 1 is 0.5-1.5 times the diameter of the cross-sectional circle of the cylinder. The honeycomb structure 2 is a part composed of a plurality of regular hexagonal honeycomb units. Each regular hexagonal The honeycomb-shaped unit is welded by six cuboid steel plates. The length of the outer wall 1 is equal to the length of the honeycomb structure 2. The honeycomb structure 2 penetrates the inner hole of the outer wall 1 and is externally connected to the inner hole of the outer wall 1. The outer wall 1 is welded and fixed, and the middle wall 3 is a c...

Abstract

The invention discloses a piezoelectric omnidirectional load detection device and aims at solving the problem of realizing omnidirectional load detection by using a piezoelectric wafer and following a honeycomb structure principle. The piezoelectric omnidirectional load detection device is composed of an outer wall (1), a honeycomb structure (2), a middle wall (3), a triangular structure (4), an inner wall (5), and a piezoelectric plate (6); by using the characteristics of the honeycomb structure, such as high strength, light weight, and good resistance to thermal shock and vibration, and in combination with a piezoelectric detection technology, the present invention provides the piezoelectric omnidirectional load detection device that is compact in structure, high in rigidity, omnidirectional, high in detection accuracy, good in stability, and good in universality, and meets load detection requirements.

Description

technical field [0001] The invention relates to a detection device in the field of load detection, more specifically, it is a piezoelectric full-angle load detection device. Background technique [0002] CNC machine tools are the main machine tools in the equipment manufacturing industry, and their technical level affects the level of the national manufacturing industry. The functions and precision levels of domestic CNC machine tools are increasing day by day, but there is still a certain gap with the CNC machine tools manufactured by developed countries in terms of reliability. The load information of the machine tool mainly includes cutting force, cutting torque, vibration and impact, etc., which is the objective basis for the reliability design of the machine tool. At present, the measurement of machine tool load information is mainly performed by a single force sensor, which has low structural rigidity, limited test angles, and requires labor-intensive installation. T...
