Thrust testing devices for linear actuators

Abstract

An object of the present invention is to provide a thrust testing device for a linear actuator, which can test thrust more accurately and greatly reduce the working intensity of test operators. For this purpose, the present invention employs the following technical solution: a thrust testing device for a linear actuator, comprising a frame and a plurality of supporting legs used for supporting the frame, characterized in that a linear actuator mounting plate and a horizontal bearing plate, which are arranged in front of one another and spaced apart from each other, are provided on the frame; the linear actuator mounting plate is fixed to the frame; a guiderail, which is arranged in a front-rear direction of the frame, is provided on the frame, and the horizontal bearing plate is fitted on the guiderail in a sliding way; a first mounting base used for being fixed to a cabinet of the linear actuator is provided on the linear actuator mounting plate, and a second mounting base used for being fixed to a jack of the linear actuator is provided on the horizontal bearing plate; and a plurality of counterweight holders are provided on a lower is side of the horizontal bearing plate, and the counterweight holders are connected to the horizontal bearing plate; and a plurality of counterweights are provided on the counterweight holders.
