Problems solved by technology

The structure of CNC machine tools has become more complex. If the product performance is evaluated by directly analyzing the reliability of the machine tool, there will be problems such as inaccurate results and large deviations. Moreover, the workload of evaluation using this method is very large, and it can be realized small
Therefore, it can be considered to use the meta-action assembly unit for reliability evaluation, but the current research on the performance of the meta-action assembly unit is still at the theoretical stage, and there is no method for the reliability test of the meta-action assembly unit

Embodiment 1

[0027] A method for reliability testing of a meta-action assembly unit (worm screw meta-action assembly unit), comprising the following steps:

[0028] (1) The mechanical and electrical products to be tested are directly decomposed into meta-action assembly units according to the structural decomposition method.

[0029] (2) Determine the specific composition of the meta-action assembly unit according to the requirements of the electromechanical product and the definition of the meta-action assembly unit.

[0030] The concrete composition of described meta-action assembly unit (referring to figure 1 ), including five parts: power source, support, executive, intermediate transmission and fasteners. And the functions of the five parts are: the power source is used to provide the power of the meta-action movement, including the motor directly providing power and the power output by the meta-action movement; the support is used to support the parts of the actuator; The actuator ...

Abstract

The invention provides a reliability test method for a meta-action assembly unit. The method is characterized in that a to-be-tested mechanical and electrical product is directly decomposed into element action assembly units according to a structured decomposition method; according to requirements of mechanical and electrical products and definition of an element action assembling unit, the specific composition of the element action assembling unit is determined, and the element action assembling unit specifically comprises a power source, a supporting piece, an executing piece, an intermediate transmission part and a fastening piece, a test bed model of the meta-action assembly unit is established, and then a meta-action assembly unit performance test on a test bed model is performed. Themethod is advantaged in that the method effectively performs performance analysis on the element action assembly unit, and improves accuracy of reliability evaluation.

Description

technical field [0001] The invention belongs to the technical field of performance analysis of a meta-action assembly unit of electromechanical equipment, and in particular relates to a method for testing the reliability of a meta-action assembly unit. Background technique [0002] Modern mechanical and electrical products are a complex system with integral functions, integrating machinery, electrical appliances, and electronic equipment. It is a high-tech product formed by integrating multidisciplinary technologies on mechanical carriers. It is characterized by a highly integrated structure, diverse functions, and powerful motion control capabilities. [0003] Electromechanical products are a whole formed by different units according to relevant rules and mechanisms. The interaction, response, joint, excitation, transmission and dissipation of the units are cumulatively expressed as the characteristics of the product. In order to realize the main function, different mechani...
