Reliability test bed and method

Abstract

The invention discloses a reliability test bed and method. The reliability test bed comprises a base, a clamping device, a striking head, a first motor and a transmission assembly, the clamping deviceis arranged on the base and is used for clamping the key switch; the striking head is arranged on the base and is spaced by the clamping device, and the striking head is arranged in a translation mode in the pressing direction close to and away from the clamping device so as to press the key switch in the moving process of the striking head; the transmission assembly is connected with an output shaft of the first motor and the striking head and used for converting rotary motion of the output shaft of the first motor into translational motion of the striking head in the pressing direction. According to the technical scheme, the first motor is used for replacing the air cylinder and the transmission assembly, rotation of the output shaft of the first motor is converted into translational motion of the striking head in the pressing direction, and therefore an original air cylinder driving mode is changed into a motor driving mode, and the rotating speed of the motor can be controlled through programming; and therefore, the movement speed and the movement displacement of the striking head are controlled.

Description

technical field [0001] The invention relates to the technical field of reliability testing of vehicle keys, in particular to a reliability testing platform and method. Background technique [0002] At this stage, the reliability test of the push-button switch for vehicles is generally carried out by the following method: use multiple small cylinders to hit each button of the switch in order to complete the reliability test. This method only needs several cylinders and a fixing mechanism. Can be done. The air pipe expands and contracts multiple air cylinders fixed on the bracket through the pressure of the air source. During the expansion and contraction process, it realizes the striking action on the sample and completes the reliability test cycle. Although this method can carry out tests on multiple buttons of the same switch in an orderly manner, the stroke and force of the cylinder cannot be controlled, and the damage to the switch will be aggravated. There are clear re...

AI Technical Summary

Problems solved by technology

Although this method can carry out tests on multiple buttons of the same switch in an orderly manner, the stroke and force of the cylinder cannot be controlled, and the damage to the switch will be aggravated. There are clear requirements for the operating stroke. If the stroke and force of the cylinder action cannot be controlled, it will naturally affect the test results and affect the judgment of the test results.
