Motor vehicle bulb vibration detection clamp and detection method thereof

Abstract

The invention discloses a motor vehicle bulb vibration detection clamp and a detection method thereof. The clamp comprises a vibrating disk fixedly installed on a vibration workbench, wherein the vibrating disk is of a cavity structure, a plurality of first through holes are arranged in the outer wall of the vibrating disk in the circumferential direction, and a clamping mechanism is arranged in each first through hole; the clamping mechanism comprises a base arranged on the vibrating disk, wherein a second through hole is arranged in the center of the base, and a locking device is arranged atthe front end of the base; the locking device comprises a supporting seat arranged at the front end of the base, wherein a semicircular first mounting hole is arranged in the supporting seat, a locking gland is movably hinged to one side of the supporting seat, and a second mounting hole is arranged in the locking gland; the mounting hole communicates with the second through hole; the rear end ofthe base is connected to a binding post on the vibrating disk; and the binding post is connected to an external power supply. According to the motor vehicle bulb vibration detection clamp and the detection method thereof, the rigid connection with the clamp and the power supply stabilization in bulb vibration detection ae realized; and objective data is given to the vibration resistance and the impact performance of the bulb, so that a scientific and accurate analysis result is obtained, and the important practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of light bulb test fixtures, in particular to a vehicle light bulb vibration detection fixture and a detection method thereof. Background technique [0002] Usually, in order to determine the quality of the product, a number of simulated environmental tests are required. Similarly, when determining the quality of motor vehicle bulb products, it is necessary to test the vibration and shock resistance of motor vehicle bulbs. This test requires multiple motor vehicle bulbs. The light bulb is fixed on the vibrating table, and it is tested under certain vibration frequency, vibration amplitude and other parameters under the electrified state. Test requirements: 1. The bulb under test and the vibrating table must vibrate synchronously, otherwise the acceleration of the bulb will be too large or insufficient; 2. The bulb under test needs to be powered on during the test. In order to meet the test requirements, a f...
