Abstract

The invention discloses a rivet dismounting device, and belongs to the technical field of dismounting tools. The rivet dismounting device comprises a machine frame, an ejector pin, an objective table and a storage part, wherein the ejector pin is arranged on the machine frame and can move in the vertical direction so as to dismount rivets on a workpiece; the objective table is arranged on the machine frame, located below the ejector pin and used for bearing the workpiece, and a flow guide groove is formed in the objective table; and the storage part is arranged on the machine frame, and the dismounted rivets can enter the storage part through the flow guide groove. According to the rivet dismounting device, the residual rivets in a shearing clamp hole can be quickly dismounted, and the residual rivets are prevented from accidentally injuring an operator.

Description

technical field [0001] The invention relates to the technical field of removal tools, in particular to a rivet removal device. Background technique [0002] The shear test is to measure the resistance performance of the material under the action of shear force, and it is one of the basic test methods for the mechanical properties of the material. During the manufacturing process of the aircraft, it is necessary to conduct a shear test on the rivets on the aircraft skin to check whether their resistance performance is qualified. [0003] When performing a shear test, the rivet sample to be tested is generally placed on a shear fixture, and the rivet to be tested is cut off by a universal testing machine and its shear strength is calculated to obtain the resistance performance of the rivet. After the shear test, the rivets were deformed under stress. Partially deformed rivets will remain in the shearing fixture holes, and the rivets remaining on the shearing fixture holes ne...
