Abstract

A horizontal linear fatigue testing machine, comprising: a cabinet, the top surface of which is an openable structure; a base plate, a frame structure, which is arranged in the upper part of the cabinet; two pairs of guide rails and sliders, and the two pairs of guide rails are respectively arranged on the two side frames of the base plate frame; Beam, the two sides of the bottom surface are connected to the upper surface of the slider, a number of through holes are arranged at intervals of the beam, and a support plate for the ball socket is arranged on the inside of the cabinet; the screw rod and its upper nut are arranged in the center of the base plate, and the two ends are connected to the The center of the front and rear frames of the base plate; the nut is set in the center of the bottom surface of the beam; the servo motor is set outside the center of the front frame of the base plate and connected with the screw; a number of driving devices are set corresponding to each through hole of the beam, and the front surface of the cylinder body is connected to the through hole of the beam On one side of the drive device, the output end of the driving device passes through the through hole of the beam, and a ball-socket block is arranged at the end of the output end; the force sensor is arranged on the ball-socket support plate; the linear displacement sensor is arranged on one side of the inner wall of the cabinet; the controller. The invention can simultaneously test the fatigue performance of a plurality of electric struts of different types.

Description

technical field [0001] The invention relates to auto parts testing equipment, in particular to a horizontal linear fatigue testing machine. Background technique [0002] The electric strut is controlled by a built-in motor and is used to support the automatic opening and closing device of the tailgate of the car. The fatigue characteristics of the electric strut are tested directly on the tailgate of the car very slowly. [0003] At present, many fatigue testing machines can measure the fatigue characteristics, fatigue life, fatigue life, Prefabricated crack and crack growth test, this universal fatigue testing machine can replace different fixtures to complete the fatigue test of a single electric strut. [0004] Although the existing universal fatigue testing machine can test the fatigue characteristics of one electric strut, the test cost will be very high when testing multiple electric struts. increase cost. Contents of the invention [0005] The object of the pres...
