Problems solved by technology

Among them, the structure of the four columns is the strongest, but the volume is relatively large, which wastes processing materials during production and processing and increases the processing time. The process is relatively complicated; the design of the structure of the three columns is based on the principle of the strongest triangular stability, but there are also shortcomings. , for example, the appearance is not beautiful, and it is not convenient to operate, which will bring inconvenience to the operator; the two-column structure is relatively simple, and the distance between the two columns can be very good for the operator to fix the loaded specimen. It is fixed on the fixture, and compared with the first two structural concepts, the raw materials are used the least, and the processing method is the simplest

Abstract

The invention discloses a fatigue testing machine. A mechanical part of the fatigue testing machine comprises a motor cover, a voice coil motor, a fixture, an upper support plate, a motor support plate, an intermediate plate, vertical columns and a bottom plate. The voice coil motor is used as a power source. The fatigue testing machine has the characteristics of high precision, high response speed, high transmission stiffness, smooth thrust, high reliability, no limitation of travel length and long life. The two vertical columns are used as main supports so that the structure is simple. Raw materials are saved in production and a cost is reduced.

Description

technical field [0001] The invention relates to fatigue testing technology of mechanical parts, in particular to a fatigue testing machine. Background technique [0002] There are four column structures, three column structures, and two column structures for fatigue testing machines with column structures. Among them, the structure of the four columns is the strongest, but the volume is relatively large, which wastes processing materials during production and processing and increases the processing time. The process is relatively complicated; the design of the structure of the three columns is based on the principle of the strongest triangular stability, but there are also shortcomings. , for example, the appearance is not beautiful, and it is not convenient to operate, which will bring inconvenience to the operator; the two-column structure is relatively simple, and the distance between the two columns can be very good for the operator to fix the loaded specimen. It is fix...
