Abstract

The invention discloses a deformation nut assembling tool, and belongs to the technical field of assembling tool. The deformation nut assembling tool comprises a handle, a support, a ball screw and a puncher pin. The support is a U-shaped support. A threaded hole is formed in the horizontal part of the U-shaped support. A threaded hole and a groove are formed in the two ends of the U-shaped support respectively. The puncher pin is in a hemisphere shape, a conical structure is arranged at the sphere top of the hemisphere, and a threaded blind hole is formed in the center of the planar part of the hemisphere. The handle is fixed into the threaded hole in the horizontal part of the support. The ball screw is installed in the threaded hole of the vertical part of the support. The puncher pin is fixed to the tail end of the ball screw and located at the end close to the groove of the U-shaped support. The axis of the conical structure of the puncher pin and the axis of the ball screw are coaxial. By means of the deformation nut assembling tool, positioning, deforming and in-place assembling of a deformation nut can be completed by one-time manual operation of a single person, and the high assembling efficiency and the high assembling accuracy are achieved.

Description

technical field [0001] The invention belongs to the technical field of assembly tooling, in particular to a deformed nut assembly tooling. Background technique [0002] The flange joints of core components such as the combustor case and turbine guider of the aero-engine are connected by deformed nuts, and the deformation of the conical surface of the deformed nuts is used to achieve the fixation with the end face holes of the flanges, such as figure 1 Shown; At present, there is no mature deformed nut assembly tool in China. Contents of the invention [0003] In view of this, the object of the present invention is to provide a deformed nut assembly tool, which can realize efficient and accurate assembly of deformed nuts of aero-engine case products. [0004] The present invention is achieved through the following technical solutions: [0005] A deformed nut assembly tool, including: a handle, a bracket, a ball screw and a punch; [0006] The support is a U-shaped frame,...
