The invention discloses a vibration test clamp. The vibration test clamp comprises a first bottom crossbeam, a second bottom crossbeam, a first top longitudinal beam, a second top longitudinal beam and multiple positioning bolts, wherein the first bottom crossbeam and the second bottom crossbeam are parallelly arranged on a vibration station and have an adjustable relative distance, the first top longitudinal beam and the second top longitudinal beam are parallelly arranged and have an adjustable relative distance and adjustable height, and the multiple positioning bolts respectively penetrate through the first bottom crossbeam and the second bottom crossbeam and are in thread connection with the corresponding bottom crossbeams to change stretching-out length of the positioning bolts stretching out of the bottom crossbeams. The vibration test clamp is advantaged in that universality is improved to a certain degree, parts in multiple shapes and dimensions can be fixed on the vibration test station, so designing vibration test clamps according to shapes of to-be-tested parts is not required, workload of workers is reduced, and vibration tests are convenient to carry out.
Description
technical field [0001] The invention relates to a fixture, in particular to a fixture for vibration tests. Background technique [0002] In order to ensure the strength of parts, vibration tests are required for parts before assembly. Before doing the vibration test, it is necessary to make a vibration test fixture to fix the parts to fix the parts to be tested on the vibration test bench. In the related art, the vibration test jig has poor versatility. When performing vibration tests on components of different shapes, it is necessary to manufacture vibration test jigs of different shapes, which increases the workload of personnel and is inconvenient for the vibration test. Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the object of the present invention is to propose a vibration test jig with improved versatility at least to a certain extent. [0004...
