Electric push rod life test device

Abstract

The invention relates to an electric push rod life test device. The electric push rod life test device is characterized in that the electric push rod life test device comprises a horizontal plate (1),a vertical plate (2) and load blocks (3); the vertical plate (2) is fixed on the horizontal plate (1) and is perpendicular to the horizontal plate (1); fixing seats (5) for mounting electric push rods (4) are fixed onto the horizontal plate (1); positioning blocks (6) and limiting blocks (7) are fixed on the vertical plate (2); the positioning blocks (6) are used for fixing upper hinges (8); theload blocks (3) are fixed onto lower hinges (9); the lower hinges (9) are connected with the push rods of electric push rods to be tested (4), so that the lower hinges (9) can be driven to swing relative to the upper hinges (8); and the limiting blocks (7) are used for limiting the downward swing of the load blocks (3). The electric push rod life test device of the invention is low in cost and iscustomizable. With the electric push rod life test device adopted, the actual working status of an electric push rod can be simulated, so that prospective design reference can be provided for the design of push rods.

Description

Technical field [0001] The invention relates to a testing device, in particular to an electric push rod life testing device. Background technique [0002] With the continuous progress of science and technology, the level of industrial automation has been greatly improved, and at the same time it has led to the widespread application of smart devices. Among them, the motion drive unit (such as electric push rod, etc.) plays a vital role, and its quality, stability, reliability, and life span directly affect the performance level of the entire mechanism. [0003] For example, the Chinese utility model patent "A Range Hood with Automatically Opening and Closing Smoke Screen" with the patent number ZL201220321941.1 (publication number CN202675417U) applied by the applicant discloses such a range hood with an electric push rod. The machine includes a box body and a fan system arranged in the box body. The box body includes a panel facing the stovetop. The panel is provided with an air ...

Problems solved by technology

Of these two solutions, the collection process of the former is too complicated and costly, and has no forward-looking guiding significance for product design; the latter can truly reflect the performance of the electric actuator, but its application range is narrow, such as some non-mass-produced expensive products. Machines are not convenient for testing and the cost of testing on finished machines is high
