Abstract

A fixture adapter plate for the tail tank vibration test. In order to solve the problem that the existing test fixture is only suitable for one size of the tail tank structure, the tail tank structure is similar and the weight is the same. Only the size of the tail tank is the same as the size of the test fixture. When it does not match, a matching test fixture is required, which leads to the problem of increased cost of the tail tank vibration test. The center of the adapter plate body of the present invention is provided with a stepped hole, and the stepped holes are successively from left to right a conical cockpit connection hole, a central hole and a conical fixture connection hole, and the inner diameter of the conical cockpit connection hole is smaller than the outer diameter , the inner diameter of the connecting hole of the tapered fixture is smaller than the outer diameter, the outer surface of the adapter plate body is provided with a flange, and there are several M10 threaded holes and several M12 threaded holes along the same circumference on the flange, each M10 threaded hole Install one M10 bolt and one M12 bolt in each M12 threaded hole. The invention is used for the vibration test of the tail compartment.

Description

technical field [0001] The invention relates to an adapter plate, in particular to a fixture adapter plate used for a tail cabin vibration test. Background technique [0002] There are many types of vibration test products used in the field of weapons. The matching vibration test fixture is to firmly fix the test piece on the vibrating worktable and transfer the mechanical energy of the vibrating table to the test piece. Its vibration is directly related to Quality of products. Existing test fixtures are only suitable for one size of the tail tank structure. During the vibration process of the tail tank, it is often encountered that the tail tank structure is similar and the weight is the same, but the size of the tail tank does not match the size of the test fixture. Just need to redesign, manufacture new test fixture, this undoubtedly makes tail tank vibration test increase cost (a set of test fixture manufacturing cost is about 100,000 yuan). In order to reduce the test...
