Comprehensive durability testing machine for automobile switch

Abstract

The invention relates to a comprehensive durability testing machine for an automobile switch. The comprehensive durability testing machine comprises a high and low temperature environment test box, aprogram-controlled power supply, a test fixture, a fixing fixture, a fixture rack, a motor driver and a motion control card; the fixture rack is movably installed in the box body of the high and low temperature environment test box; the program-controlled power supply, the motor driver and the motion control card are all positioned outside the high and low temperature environment test box; the program-controlled power supply is connected with the automobile switch via a wire; the motor driver is connected with a high and low temperature motor of the test fixture via the wire; and the motion control card is connected with the motor driver via a cable. The comprehensive durability testing machine has the beneficial effects that the comprehensive durability testing machine of the automobile switch has the temperature and humidity adjustment function, can be applied to the tests of the pressing type automobile switch, the plugging type automobile switch, the toggle type automobile switch and the knob type automobile switch, and can judge the success rate of the automobile switch through performing current monitoring on the automobile switch in the test via the program-controlled powersupply.

Description

technical field [0001] The invention relates to the technical field of automobile switch detection, in particular to a comprehensive durability testing machine for automobile switches. Background technique [0002] At present, most of the durability testing machines on the market have the following problems: 1. Single structure, which can only be used to test the pressing structure; 2. It is difficult to control the strength and easily cause product damage; 3. The success rate cannot be confirmed during the test; 4. Can only be tested at room temperature. [0003] As the standards of the automotive industry are updated day by day, the old equipment can no longer meet the requirements of the standards, so a durable test machine with functions of pressing, plugging, pulling, and rotating is needed to be combined with an environmental chamber to form a durability + temperature +The humidity test system is more in line with the use conditions of auto parts, making the experimen...
