Novel loading equipment for rigidity test of material and use method thereof

Abstract

The invention discloses a piece of novel loading equipment for a rigidity test of a material. The loading equipment comprises a rack (5), a loading trolley (9) capable of moving 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), the external thread sleeve is used for extending into the hollow inside of a rotating shaft (6) and is in screw-thread fit with an internal thread ring part (71) at 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 drive motor (8), the drive motor is installed on the right side surface of a boss (51) of the rack (5), a damping base plate (86) is arranged at the bottom part of the drive motor (8), a reinforcing rib plate (87) is arranged between the damping base plate (86) and the boss (51), and the damping base plate (86) is used for reducing the shaking force produced by the drive motor (8) in operation, so that the operation stability of the drive motor (8) is improved.

Description

technical field [0001] The invention relates to the field of material testing equipment, in particular to a new type of loading equipment for material rigidity testing and a method for using the same. 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,...

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
