Fixing device and semi-ring fixing method

Abstract

The invention discloses a fixing device and a semi-ring fixing method. The fixing device comprises a first support, a first bolt, a first movable joint bolt, a second support, a second bolt and a second movable joint bolt, wherein an U-shaped groove is formed in the upper end of the first support, the first bolt penetrates through the hole in one end of the first movable joint bolt and then is placed in the U-shaped groove, the other end of the first movable joint bolt is detachably connected with the first support, the second movable joint bolt is detachably connected with the second support,the hole faces upwards, the second movable joint bolt can move up and down along the second support, and the second bolt is arranged in the hole of the second movable joint bolt. The fixing device iseasy to manufacture, convenient to use and reliable in quality, the manufacturing difficulty and the installation difficulty of the fixing device can be reduced by adopting the fixing device to fix the semi-ring, in particular, the problem of semi-ring deformation caused by the coaxial error of the two support holes in the existing fixing device is effectively solved, and the quality hidden danger is eliminated.

Description

technical field [0001] The invention belongs to the field of aero-engine manufacturing, and in particular relates to a storage and transport fixing device and a fixing method for an engine half-ring. Background technique [0002] Due to the special structure of the half ring of the new engine device, it needs to be installed and fixed with a special fixing device during storage and transportation. According to the structural characteristics of the novel device half-ring, it is necessary to install and fix on the fixing device through two coaxial first half-ring eye holes 31 on the left, the second half-ring ear hole 32 and a support plane on the right. [0003] Such as figure 1 with figure 2 As shown, the existing fixing device includes an underframe 1, a support platform 2, a hook assembly 3, a first perforated support 4, a second perforated support 5, a latch 6, a nut 27, a washer 28, and a screw 29. When in use, first place the right side support plane on the half rin...
