Abstract

This paper describes a small carefully tension and compression testing machine supplies quality inspection process is widely used in its design. For structural features of the text and movement pattern of the testing machine was carefully described. Tension and compression testing machine building materials quality inspection process is an essential tool that makes building materials quality has been the emergence of digitized criteria, it is capable of all kinds of building materials such as brick, precast concrete panels, etc. tension and compression testing detection of mechanical properties to determine whether compliance with building requirements.

Design focus mainly include: selection and design of the hydraulic cylinder tension and compression testing machine body structure, elevating structure and movement pattern, the stepper motor. The manual pull in determining the overall structure of the design pressure testing machine premise of its various parts stress analysis and design calculations and to determine its overall exercise program, the last of the various components related check and make sure that all parts final value dimensions.

The graduation project using a variety of modern mechanical design methods, in particular the use of computer-aided design (AutoCAD) method, the computer will be in tension and compression testing machine design drawings CAD technology, which greatly improves the efficiency of the design, saving time.

Keywords: Small tension and compression testing machine elevating screw sprocket drive mechanism hydraulic cylinder mechanism reducer mechanism
