Problems solved by technology

In addition to the uncertainty of the installation position in space, a certain type of fuel pump regulator mainly faces four major problems during the installation process: 1. The product itself is heavy; 2. The shape and structure are complex; 3. There are many installation constraints. On the other hand, the cooperation of the inner and outer spline shafts is constrained by the installation of positioning pins; 4. The product is installed at a high position from the ground, and it is difficult to observe the cooperation of the inner and outer splines, and the surrounding installation space is narrow
The installation time is very long, the work efficiency is low, and the outer surface of the drive shaft and accessories of the product is easily damaged during the installation process
Similarly, other accessories of the engine, including accessory casings, generators, etc., also face the problem of difficult installation

Embodiment Construction

[0026] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0027] Such as Figure 1-2 Shown:, a spline-aligned top-feeding installation method, characterized in that,

[0028] Including the following steps:

[0029] Step 1: Put the installed fuel pump regulator on a flexible head of a jacking device for spline alignment installation;

[0030] Step 2: The flexible plug designs the positioning block according to the shape of the pump adjustment, realizes the rapid positioning of the pump adjustment, and positions the pump adjustment to the design state;

[0031] Step 3: Bind the fuel pump regulator and the flexible head together in a criss-cross pattern with locking straps;

[0032] Step 4: Insert the positioning shaft at end a of the rocker-arm plane calibrator into the inner spline of the accessory casing, and at the same time insert the b-end of the double-headed positioning pin into the pin hole on the mounting sur...

Abstract

The invention relates to a conveying-to-top and installation method with spline alignment. The method comprises the following steps that a fuel pump regulator is installed on a flexible top of a conveying-to-top device to position the fuel pump regulator, the fuel pump regulator and the flexible top are fixed together, the ends of a calibrator are inserted into corresponding gearbox correspondingpositions, and the angle of the flexible top is regulated to make bubbles of level bubbles enter and stabilize in the middle position of a horizontal scale panel; the top conveying height of the conveying-to-top device is regulated, and the rocker arm-type planar calibrator is taken out; the conveying-to-top device is pushed, the fuel pump regulator is sent into the accessory gearbox slowly, and the conveying-to-top device is slightly regulated until the fuel pump regulator and the accessory gearbox are completely attached. According to the method, through multiple-dimension angle regulation,efficient alignment is achieved; by replacing a conveying-to-top base, the conveying-to-top and installation requirements of multiple products are met.

Description

technical field [0001] The invention creates a ceiling-mounted installation that is suitable for an installation environment with complex and changeable spatial reference planes, many installation constraints, and a scene with high requirements for coordination quality. Background technique [0002] Aeroengines are affected by the ground where the aircraft is parked, the volume of fuel in the fuel tank, the load, etc., resulting in different spatial positions of the engine, so the spatial position of the aeroengine pump adjustment accessories is also changeable. In addition to the uncertain installation position, a certain type of fuel pump regulator mainly faces four major problems during the installation process: 1. The product itself is heavy; 2. The shape and structure are complex; 3. There are many installation constraints. On the one hand, it needs to meet The coordination of the inner and outer spline shafts, on the other hand, is constrained by the installation of po...
