Reliability test system for retractable protective cover with multi-dimensional loading function

Abstract

The invention discloses a telescopic protective cover reliability test system with multi-dimensional loading function, comprising: a driving device, a simulation test part and a ground level iron, the driving device adopts a hydraulic cylinder as a power source, and among the simulation test parts: a feed transfer device Connected between the hydraulic cylinder and the movable end of the tested piece, the electromagnetic loading device is installed under the tested piece, the slide rail device is set on both sides of the tested piece, the clamping device clamps the fixed end of the tested piece, and the environment simulation device The sliding nozzle is slidingly installed above the tested piece and connected with the feed transmission device. The state detection device is composed of a hydraulic sensor, an infrared temperature sensor and a humidity sensor. The invention can carry out multi-dimensional loading on the telescopic protective cover, simulate the actual working conditions to a large extent, monitor the functional state of the protective cover in real time, and realize the comprehensive test on the function and state of the telescopic protective cover.

Description

technical field [0001] The invention belongs to the technical field of reliability testing of functional parts of numerical control machine tools, is suitable for telescopic protective covers of numerical control machine tools, and in particular relates to a reliability test system for telescopic protective covers with multi-dimensional loading functions. Background technique [0002] CNC machine tools are essential key equipment in modern manufacturing systems and modern manufacturing equipment with high-tech content. The quality of CNC machine tools is an important indicator to measure the degree of industrial modernization of a country, which affects the country's manufacturing capacity and comprehensive national strength. Although my country's machine tool industry started relatively late, it has developed rapidly. In recent years, there has been significant growth in technology and market size, and it has become the world's largest machine tool production and sales coun...

Problems solved by technology

[0004] In the prior art, the existing telescopic protective cover test device generally uses a sprocket and chain structure to control the telescopic opening and closing of the telescopic protective cover. This structure can only drive the telescopic protective cover to be tested, and the device The added cutting fluid spray assembly is a static structural design, and in the actual use of the CNC machine tool, the telescopic protective cover will also be subjected to loads including: horizontal, vertical and vertical along the telescopic direction. The existing The test device obviously cannot realize this loading function. In addition, the structure of the static cutting fluid spray assembly cannot simulate the working environment of the telescopic protective cover in the dynamic telescopic state during actual use. Therefore, the working environment simulated by the existing telescopic protective cover In addition, the existing test device can only detect serious faults such as disconnection of the guard plate of the protective cover and liquid leakage, and cannot detect and analyze the motion state and functional state of the telescopic protective cover in real time. , it is difficult to meet the current demand for a comprehensive test of the reliability of the retractable protective cover
