A fixing device and half-ring fixing method

Abstract

The invention discloses a fixing device and a half-ring fixing method. The fixing device includes a first support, a first latch, a first swing bolt, a second support, a second latch and a second swing bolt. The upper end of the seat is provided with a U-shaped groove, and the first pin is placed in the U-shaped groove after passing through the hole at one end of the first hinged bolt. The other end of the first hinged bolt is detachably connected with the first support, and the second hinged bolt The bolt is detachably connected to the second support with the hole facing upwards, the second swing bolt can move up and down along the second support, and the second bolt is placed in the hole of the second swing bolt. The invention is easy to manufacture, easy to use, and reliable in quality. Using the fixing device to fix the half-ring can reduce the manufacturing difficulty and installation difficulty of the fixing device, and especially effectively solve the problems caused by the coaxiality error of the two support holes in the existing fixing device. The half-ring deformation problem eliminates the hidden danger of quality.

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...
