Stackable large displacement electromagnetic loading machine and loading method therefor

Abstract

The invention discloses a stackable large displacement electromagnetic loading machine and a loading method therefor. The loading machine comprises a connection bench connected with an operation mechanism, guide columns fixed at the lower end of the connection bench and coil support frames fixed on the guide columns, wherein inner coils are wound on the coil support frames; inner cylinders are arranged within distance reserved at the external ends of the inner coils; an external coil set support frame is fixed on the outer surfaces of the inner cylinders; external coil sets are arranged on the external coil set support frame; and the plurality of guide columns and the inner cylinders are respectively connected with each other via guide column connection pieces and inner cylinder connection pieces. The loading method adopts the steps as follows: the inner coils are electrified; the positions of the inner coils are changed with the motion of the guide columns; and the upper external coil sets and the lower external coil sets of the inner coils are switched on or switched off according to practical demands. According to the invention, a high precision load can be provided for reciprocating type linear loading in a larger travel; the output load and travel of the loading machine are enlarged in a stackable manner, therefore, the loading machine has the characteristics of energy conversation, high efficiency, convenience in mounting and wide application range.

Description

technical field [0001] The invention relates to an electromagnetic loader, in particular to a superimposed large-displacement electromagnetic loader and a loading method thereof. Background technique [0002] Loading machines have been widely used in engineering fields such as oil exploration engineering, aerospace engineering, civil engineering and water conservancy engineering, and as actuating equipment for experimental research. The existing loading equipment mainly includes motors and hydraulic systems, but the motors and hydraulic systems are in the reciprocating linear system. There are still many problems in the loading of large displacement. It is difficult for ordinary motors to work under reciprocating loading. Although the emergence of linear motors and bidirectional motors can overcome the problem of reciprocating linear large displacement loading to a certain extent, their cost is expensive. , and cannot provide enough power, and the hydraulic system still has ...
