Abstract
The invention provides a general fixing and clamping device used for a three-axis vibration test. The general fixing and clamping device comprises a bottom platform, Y-direction fixing baffle plates, X-direction fixing baffle plates and Z-direction fixing pressing blocks, wherein the bottom platform is connected with the lower side surfaces of the Y-direction fixing baffle plates; the bottom platform form a vibration table connecting ends, and the upper side end surfaces of the Y-direction fixing baffle plates are connected with the Z-direction fixing pressing blocks; two end surfaces of the Y-direction fixing baffle plates are respectively connected with one X-direction fixing baffle plate; each X-direction fixing baffle plate is provided with an avoidance groove; the Y-direction fixing baffle plates include a first Y-direction fixing baffle plate and a second Y-direction fixing baffle plate which are adjacent to each other; and one end of each Z-direction fixing pressing block is connected the upper side end surface of the first Y-direction fixing baffle plate, and the other end of each Z-direction fixing pressing block is connected the upper side end surface of the second Y-direction fixing baffle plate. According to the invention, the installation difficulty of a test piece is lowered, and smooth developing of the three-axis vibration test is ensured; in addition, the bottom platform and the Y-direction fixing baffle plates are connected through reinforcing ribs, and vibration used in the device is reduced.
Description
Technical field [0001] The invention relates to a vibration fixing and clamping device, in particular to a universal fixing and clamping device for triaxial vibration test. Background technique [0002] Triaxial vibration test belongs to the cutting-edge technology of vibration test. It is relatively rare in China that triaxial vibration test is used in actual engineering test. In the triaxial vibration test, due to the limited size of the vibration test bench surface, and the specification and number of fixed threaded holes on the bench surface are also limited, the test piece is generally connected to the vibration test bench surface through a fixed clamping device. Since a fixed clamping device is used to connect the vibrating table and the test piece, the vibration and energy of the vibrating table cannot be directly transmitted to the device under test, but first transmitted to the fixed clamping device, and then through the fixed clamping device Passed to the device. Ther...
