Example Embodiment

[0011] Hereinafter, the present invention will be further described in detail through specific embodiments.

[0012] See also figure 1 , figure 2 with image 3 ——The schematic diagram of the structure of the invention, the schematic diagram of the installation of the test piece and the schematic diagram of the pressure plate. The base 1 designed in the present invention is fixed on the test bench by fasteners to complete the installation of the test fixture. The test piece 4 is fixed on the pressure plate 2 by a fastener 5, and the pressure plate 2 is fixed on the base 1 by a fastener 3. The fastener 3 can be moved and adjusted in the T-slot of the base 1 to meet the transverse installation distance of the test piece, and the pressure plate can be adjusted to meet the longitudinal installation distance of the test piece through the waist-shaped hole of the pressing plate 2. After the adjustment is completed, tighten the fastener 3 to complete the installation of the test piece...

Abstract

The invention relates to a universal test fixture. A base is connected with a test platform; press plates are connected on the base through fasteners; a test specimen is connected on the press plates through fasteners. The test fixture is simple in structure and reduces the processing cost and processing cycle, and one fixture can achieve vibration, shock, acceleration and other tests of all test specimens fixed by mounting lug sheets.

Description

technical field [0001] The universal test fixture is mainly used for vibration, shock, acceleration and other tests of test pieces with mounting lugs. The invention designs a universal test fixture. Background technique [0002] With this universal test fixture, without changing the state of the test bench, all the tests in the three axial directions of vibration and impact and six directions of acceleration can be completed. At the same time, the universal test fixture is suitable for any installation size belt Test pieces with ears mounted. [0003] Due to the different installation dimensions of the ear-type test pieces, the existing test fixtures are all dedicated, and there is no universal test fixture at present. Due to the lack of general-purpose test fixtures, the cost of test fixtures is increased, the processing cycle is prolonged, and the time for disassembling and assembling fixtures during the test process is increased, and a large number of test fixtures are ...
