Abstract

The invention discloses a conical connecting rod for a small installation surface of a test piece, which comprises a conical connecting piece, a first connecting plate and a second connecting plate, the large end surface of the conical connecting piece is connected to the first connecting rod The plate is fixedly connected, the small end surface of the tapered connector is connected to the second connecting plate, the first connecting plate is connected to the fixture through a plurality of first mounting screws, and the second connecting plate is connected to a plurality of second connecting plates. The mounting screws are connected to the specimen. The invention discloses a tapered connecting rod used for the small installation surface of a test piece, which realizes the high-strength connection form between the small installation test piece and the vibrating fixture, and has the value of popularization and use.

Description

technical field [0001] The invention belongs to the technical field of mechanical connection, and in particular relates to a tapered connecting rod used for a small installation surface of a test piece. Background technique [0002] In some test pieces, especially engine-type test pieces, limited by the shape space, the connection with the surrounding is carried out through several thin connecting rods, and the installation surface is small. If the thin connecting rod is directly used to connect the fixture for vibration test, the thin connecting rod is easy to break due to its weak stiffness, and the specimen will vibrate strongly, making the vibration test of the specimen difficult to control. The conical connecting rod method can realize the connection between the small installation test piece and the vibration fixture, and has high strength to meet the requirements of vibration test control. Therefore, it is necessary to develop a new type of conical connecting rod. C...
