Problems solved by technology

Due to the dynamic nature of load changes and the immediacy of measurement, this method is prone to 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
And although some equipment can guarantee the measurement accuracy, the cost is high and the maintenance work is complicated

Abstract

A loading device comprises a machine frame (5), a loading cart (9) arranged on the machine frame (5) and capable of moving left and right, and a clamping table (11) fixed to the left end of the machine frame (5) and used for clamping a workpiece (1), wherein an external thread sleeve (7) is fixedly connected to the right side of the loading cart (9) to be used for stretching into the hollow inside of a rotary shaft (6) and being in screw thread fit with an internal thread ring portion (71) at the left end of the rotary shaft (6), and the right end of the rotary shaft (6) is in power connection with an output shaft of a driving motor (8) on the right side face of a boss (51) of the machine frame (5); four or more cooling fins (81) are longitudinally arranged on the surface of a shell of the driving motor (8) to be used for absorbing and dissipating heat generated during operation of the driving motor (8), so that the heat dissipation 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 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. Moreover, altho...
