Embodiment Construction

[0011] 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 some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0012] First of all, before describing the embodiments, it is necessary to explain some terms appearing in this text. For example:

[0013] Herein, terms such as "first" and "second" may be used to describe various elements, but these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a "first" element could also be termed a "second" element without departing from the teachings of the prese...

Abstract

The invention provides a device for detecting an extending friction force of an oil cylinder. The device comprises the oil cylinder, a laser obstacle detector, a base, an oil pressure gauge, a pressure regulating valve and an oil source, wherein a cylinder rod of the oil cylinder is close to a beam of the laser obstacle detector; a cylinder barrel of the oil cylinder is fixed on the base; an oil inlet of the oil cylinder is connected with the oil pressure gauge by the aid of a pipeline; the oil pressure gauge is connected with the pressure regulating valve by the aid of a pipeline; and the pressure regulating valve is connected with the oil source by the aid of a pipeline. The device is simple in structure, low in price, convenient to use and capable of detecting the internal friction force of the oil cylinder conveniently and quickly, so that bases for design and oil cylinder model selection are increased.

Description

technical field [0001] The invention relates to a detection device for the frictional force of oil cylinder extension. Background technique [0002] Hydraulic transmission has become an indispensable member of the transmission system because it can generate a lot of force with a small volume. As one of the most important actuators of hydraulic transmission, the oil cylinder has been widely used in various fields. When selecting an oil cylinder, the friction inside the oil cylinder is usually ignored, and the product of the pressure received by the oil cylinder and the working area of ​​the oil cylinder is used as the output force of the oil cylinder. Since the friction inside the oil cylinder is unknown, for safety, the model is often calculated Basically, enlarge the model to use or increase the oil pressure to use. Serious waste of resources and energy. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a detect...
