Displacement-adjustable button fatigue detection device

Abstract

The invention provides a displacement-adjustable button fatigue detection device which comprises a base frame and a detection mechanism, and the detection mechanism is installed on the base frame. The detection mechanism comprises a motion loading unit and an adjusting clamping device. The motion loading unit comprises a driving unit, a driven arm, a loading arm, a main body guide rail, a main body sliding block and a contact; the main body guide rail is installed on the base frame, the driving unit is connected with the driven arm, the driven arm is fixedly connected with the loading arm, the loading arm is fixedly connected with the main body sliding block, the main body sliding block is in sliding fit with the main body guide rail, and the contact is connected to the loading arm. The adjusting clamping device comprises a lateral sliding rail and a clamp, the clamp comprises a lateral sliding block, a bow-shaped frame and a fixing rod, the fixing rod is installed on the bow-shaped frame, the lateral sliding rail is installed on the base frame, the lateral sliding block is in sliding fit with the lateral sliding rail, and the lateral sliding block is connected with the bow-shaped frame. The displacement-adjustable button fatigue detection device is simple in structure, low in cost and small in occupied area, has multiple degrees of freedom, and is suitable for various gear handles.

Description

technical field [0001] The invention relates to the technical field of fatigue detection, in particular to a displacement-adjustable button fatigue detection device. Background technique [0002] The automatic transmission handle needs to pass the fatigue approval test before mass loading. As a component that is in direct contact with the driver and control personnel, the detection of the handle button is particularly important. Traditional detection devices mostly use large-scale industrial control equipment. A typical solution is to use an industrial computer to control the rotation of the motor, convert the rotational motion of the motor into linear motion, and load the test piece through the loading rod. The end of the loading rod is supplemented by force The value sensor records the loading curve for display on the control cabinet screen. This kind of scheme can realize the precise control of the force value. Because it is a real-time monitoring signal, a large amount ...

Problems solved by technology

This kind of scheme can realize the precise control of the force value. Because it is a real-time monitoring signal, a large amount of data will be generated at the same time, resulting in system redundancy; due to the use of motors and industrial computers, etc., this kind of scheme is expensive, high maintenance cost, and occupies a large area. , the number of tested parts to be tested at the same time is generally not more than 4. At the same time, different tooling fixtures need to be made to match the installation of shift handles of different models, and the cycle to complete the test is long.
