A universal comprehensive test fixture for rail transit product chassis

Abstract

The invention discloses a comprehensive test clamp general for track traffic product cases. The comprehensive test clamp comprises a pair of clamping plate assemblies. The one pair of clamping plate assemblies are arranged at left and right sides at an interval. A positioning space of the product case is formed between the pair of clamping plate assembly. The clamping plate assembly comprises a horizontal plate and a vertical plate. The horizontal plate is provided with a first connection hole used for the connection with a comprehensive test platform. The vertical plate comprises a body part and an installation part extending towards the positioning space. Upper and lower ends of the installation parts are respectively provided with at least one group of second connection holes used for the installation of the product case. The number of the second connection holes in the same group is larger than two, and the second connection holes are arranged in the vertical direction. The comprehensive test clamp has the advantages that the structure is simple, the adjustment is convenient, and the comprehensive test clamp can be matched with a plurality of product cases different in model.

Description

technical field [0001] The invention relates to a test device for rail transit product cabinets, in particular to a universal comprehensive test fixture for rail transit product cabinets, which is suitable for testing medium and low-quality product cabinets under medium and low-intensity vibration stress. Background technique [0002] Comprehensive test benches such as temperature, humidity and vibration tests are often used when performing strengthening tests, accelerated life tests or accelerated degradation tests on a certain board in box-type components such as TCU, DCU, terminal chassis, and central machine of rail transit products. To conduct tests under various stresses, it is necessary to insert the board to be tested into the chassis slot, then customize the fixture according to the size and specification of the chassis, and use the fixture to fix the chassis on the vibration, temperature and humidity comprehensive test bench. The function of fixing and transmitting...

Problems solved by technology

[0003] Most of the product chassis are flat at the bottom, which are fixed by bolts at the four corners of the front side. Different chassis have different shapes and sizes, and the positions of the bolts at the four corners are also different. According to their use characteristics and test methods, it is often necessary to design and manufacture fixtures separately. The test period is prolonged and the cost is high; as the types of product chassis increase, the types of fixtures are also increasing, which wastes resources and takes up laboratory space
