Loading device for testing and use method thereof

Abstract

A loading device for testing comprises a rack (5), a loading trolley (9) which can move left and right on the rack (5), and a clamping table (11) fixed at the left end of the rack (5) and used for clamping a workpiece (1), wherein the right side of the loading trolley (9) is fixedly connected with an external thread sleeve (7) for extending into a hollow interior of a rotating shaft (6) and being matched with a thread of an internal tread ring part (71) of the left end of the rotating shaft (6); the right end of the rotating shaft (6) is in power connection with an output shaft of a driving motor (8) mounted on the right side face of a boss (51) of the rack (5); the surface of an outer shell of the driving motor (8) is longitudinally provided with more than or equal to four radiating fins (81), and the radiation fins (81) are used for absorbing and radiating heat generated during the running of the driving motor (8), so that the heat radiating area of the driving motor (8) is increased.

Description

technical field [0001] The invention relates to the field of material testing equipment, in particular to a loading device for testing and a using method thereof. Background technique [0002] The rigidity test of the material is an important index for the material performance of the workpiece. Materials may deform differently under different loads and thus exhibit different stiffness properties. Some existing testing equipment continuously applies gradually increasing loads to materials and measures the amount of deformation that occurs during the process. Due to the dynamic nature of load changes and the immediacy of measurement, this method is prone to cause measurement errors. For equipment with fixed value applied load, due to the discreteness of fixed value, it is difficult to obtain the point performance of expected value at any time. Moreover, slight fluctuations in the load are prone to occur during the hold of a fixed value, resulting in measurement errors. Mor...
