Embodiment Construction

[0031] like figure 1 , figure 2 , image 3 As shown, a fastener lateral vibration test device includes a mounting table 1, a sealing cover 2 and a semiconductor cooling chip 3, the mounting table includes a vertical plate 12 extending upward, and a horizontal mounting sleeve is provided on the vertical plate 12 13. The fastener 10 to be tested is installed on the vertical plate 12 through the horizontal installation sleeve 13. The installation table 1 is provided with a drive assembly that drives the horizontal installation sleeve 13 to reciprocate up and down on the vertical plate 12. The horizontal installation The sleeve 13 is provided with a first load cell 5 for measuring the axial pretightening force of the fastener, and the crank mechanism is provided with a second load cell 6 for detecting the lateral pretightening force of the fastener under test. The vertical plate 12 is provided with a displacement sensor 7 that detects the lateral displacement of the fastener un...

Abstract

The invention relates to a transverse vibration test device for a fastener. The device comprises an installation platform, a sealing cover and a semiconductor refrigeration piece, wherein the installation platform is provided with a vertical plate, a driving assembly is disposed on the installation platform, the semiconductor refrigeration piece comprises an absorption part and a release part, theabsorption part is attached to the driving assembly, the release part is tightly attached to the bottom of the installation platform, and the installation platform is also provided with a refrigeration device. The device is advantaged in that: a measured fastener is sealed on the vertical plate of the installation platform through the sealing cover, the heat of the driving assembly is absorbed through the semiconductor refrigerating piece and heat release is carried out, temperature heating in the sealing cover is realized, cooling treatment is carried out on the sealing cover by the refrigerating device, the temperature in the sealing cover can be quickly reduced, different tests in high and low temperature environments are met, the heat generated by the driving assembly in the test process is absorbed through the semiconductor refrigerating piece, heat recycling can be realized, heat emission of the driving assembly is reduced, and energy conservation and emission reduction of energy sources are realized.

Description

technical field [0001] The invention relates to a fastener transverse vibration test device. Background technique [0002] Fasteners are a type of mechanical parts that are used for fastening connections and are widely used. They are used to fasten two or more parts (or components) and fasten them into a whole. Generally speaking, while the fasteners are connected by threads, the performance of most threaded connections depends on the size and stability of their axial preload. However, when the threaded connections are disturbed by external loads, especially lateral vibration loads When the threaded connection is prone to loosening and failure, the threaded connection force is gradually reduced or even completely lost, which often leads to very serious personal safety and property losses. Since the fasteners will also experience low temperature and high temperature working environments, and the test The temperature of the testing machine is normal temperature, which cannot ...
