Embodiment Construction

[0017] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] Automatic test method of electric push rod characteristics:

[0019] (1) Turn on the power of the tester first;

[0020] (2) Put the electric push rod into the test position of the fixed table according to the use requirements of the tester;

[0021] (3) Input the test temperature, the production date of the tested piece, select the model specification of the tested piece, the force range, the test method, etc.;

[0022] (4) Start the test, the computer controls the output signal of the switch input board to connect the power supply of the electric push rod, and starts timing. When the push rod moves to the maximum displacement and contacts the pressure sensor, the system pressure is automatically zeroed; continue to count and record the force Changes; during the test, the real-time data of force and time are dynamically displayed, ...

Abstract

The invention discloses a method for automatically testing characteristics of an electric push rod. By the aid of the method, the characteristics of the electric push rod can be automatically tested, the maximum thrust of the push rod and required time duration of a process that the electric push rod is energized and then moves to the maximum distance can be automatically recorded, and a characteristic curve variation diagram is displayed on a computer; the test is automatically completed after a tripping switch acts in a measurement process; and a test result can be inquired, and a test report is printed via a printer. A test device used in the method mainly comprises the computer, a PC (personal computer) bus on-off output interface board, a PC bus analog input interface board, a pressure sensor (consisting of a conversion interface board) and a testing table for fixing the electric push rod. Software for implementing the method is developed by VB6.0 (visual basic 6.0) software. The method has the advantages of simplicity and convenience in operation, audio-visual user interface, convenience in maintenance and capability of improving automation degree of the test, detection precision and detection efficiency.

Description

technical field [0001] The invention relates to a method and device for automatically testing the characteristics of an electric push rod, which are used for realizing the automatic test on the characteristics of an electric push rod, and belong to the field of industrial product detection. Background technique [0002] An electric push rod is an electric drive device that converts the rotary motion of an electric motor into the linear reciprocating motion of a push rod. It can be used as an execution machine for various simple or complex technological processes to realize remote control, centralized control or automatic control. Because it is more hydraulic, the pneumatic transmission mechanism has the characteristics of simple structure, low price and strong adaptability, so it has been paid more and more attention by people. As early as the 1950s and 1960s abroad, it has been widely used in various fields such as industry, mining, and transportation. Since my country's ...
