Embodiment Construction

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0026] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, in t...

Abstract

The invention provides a test device for a linear driving power device, which comprises a base, a pulley set arranged on the base, an adjusting and balancing weight block set, a force sensor and an anti-rotation mechanism, wherein the pulley set includes at least one fixed pulley and a connecting rope arranged on the fixed pulley, the first end of the connecting rope is connected with the adjusting and balancing weight block set, the second end of the connecting rope is connected with the force sensor, the adjusting and balancing weight block set applies a loading force to an output shaft of the linear driving power device through the connecting rope and the force sensor, the anti-rotation mechanism is arranged between the linear driving power device and the force sensor, the anti-rotationmechanism carries out linear motion along the output shaft of the linear driving power device, and the output shaft of the linear driving power device is locked on the anti-rotation mechanism and used for restricting the rotation of the output shaft of the linear driving power device. The testing device of the technical scheme is provided with the anti-rotation mechanism, so that the linear loading for the output shaft of the linear driving power device is guaranteed; and the whole testing device is simple in structure, easy to operate and wide in application range.

Description

technical field [0001] The invention relates to the technical field of test systems, in particular to a test device for a linear drive power device. Background technique [0002] Electric cylinders are generally composed of three parts: motor, reducer and cylinder. It is powered by a servo motor or a stepping motor, and converts the motor's rotational motion into a linear motion to provide precise positioning and a device with a certain locking function. Electric cylinders are widely used in automotive, aviation, national defense and other fields. In the context of large-scale applications, the mechanical performance test of electric cylinders becomes indispensable, and among these mechanical performances, most of them need to apply loading force to electric cylinders. In the prior art, it is mainly aimed at multiple static indicators of electric cylinders and dynamic performance indicators under different loads, but no further improvement has been made to the test device ...
