Problems solved by technology

[0003] At present, in order to decompose the guider and the stationary vane ring from the machined assembly of the transition section, the method of turning off the outer casing is adopted, and the outer casing is destructively processed during the turning process, causing the outer casing to be scrapped
Moreover, occupying equipment will cause relatively large consumption of manpower and material resources.
Most of the current decomposition studies are aimed at the decomposition of blind holes, light hole bushings, and inner and outer rings of bearings. This type of decomposition is a tire-expanding structure, and the decomposition is achieved by the static friction force of the pulling head close to the bushing or inner ring wall. , while the circumference of the vane ring and the guide are covered with blades, this method is not suitable

Embodiment

[0047] Take the decomposition of the high-pressure inlet guide of the gas generator as an example: the guide is assembled with the outer casing through thermal assembly, and after the 8 guide pins in the radial direction are disassembled, 8 guide pin holes are left on the outer ring. 4 Select the pin-type structure, manually insert the pin 6 into the guide pin hole of the guide (depth 9mm ~ 12mm), tighten the screw 5 (adjustment range 3mm ~ 8mm), connect the puller 4 and the guide together, insert the pin 8. To prevent the blade from being rotated and damaged by the pulling head 4, tighten the lock nut 7, connect the connecting plate 2 and the pulling head 4 together, the end surface of the pulling head 4 is attached to the connecting plate 2, check that the 0.02mm feeler gauge does not pass through the seam, Ensure that the 4-axis of the head is vertically upward. Repeat the above steps to sequentially connect and fix the 8 pulling heads 4 with the connecting plate 2 to ensur...

Abstract

The invention discloses a disassembly mechanism of a matching component, which includes a support, a connecting plate, a stud and several pulling heads; Fitting; one end of the stud is sleeved with a nut, and the other end is fixedly connected to one end of the connecting plate through the stud hole opened on the upper layer of the support; one end of the puller is fixedly connected to the connecting plate, and the other end is connected to the parts to be disassembled. The operation is simple and convenient, does not occupy existing processing equipment resources, avoids scrapping damage to mating components by lathe processing, takes out parts to be disassembled without damage, effectively utilizes available resources, saves manufacturing costs for reprocessing, and shortens supporting cycle.

Description

technical field [0001] The invention belongs to the field of assembly disassembly, and relates to a disassembly mechanism for matching assemblies. Background technique [0002] In the process of product replacement or other reasons that need to replace some parts that have been installed, some parts have interference during assembly, and the assembly is realized by hot fitting. It is very difficult to disassemble such parts, and the decomposed parts generally need to be When reinstalled and used, it must be decomposed without damage. For example, see Figure 5 , The factory-equipped gas generator is returned to the factory, and the five-branch transition section is replaced with a new structure transition section. In order to make reasonable use of resources, after the five-branch transition section is returned to the factory, it is disassembled to the state of the vane ring and the guider according to the drawings, allowing it to be used for the assembly of the transition ...
