A precision top feeding device with multi-dimensional angle adjustment

Abstract

The invention relates to a precision conveying and jacking device with a multi-dimensional angle adjustment function. The precision conveying and jacking device is mainly composed of a replaceable flexible jacking head, an adjustable bracket, a hydraulic assembly, an adjustable staypole assembly and a universal base plate. The replaceable flexible jacking head comprises positioning blocks made ofa non-metallic material, a tray, adjusting screws, an adapter block and a base. The adjustable bracket comprises a handle, a screw nut, a thrust ball bearing, bracket plates, a shaft retaining ring, asliding block, a steel ball and the like. The adjustable staypole assembly comprises a hoop slidably matched with a jacket, staypoles, fasteners, locking nuts and adapter forks. The hydraulic assembly is mainly composed of a piston rod, a top cap, an oil cylinder, the jacket, a base, an oil return valve assembly, a small oil pump, a large oil pump, a small oil pump pedal, a large oil pump pedal,multiple oilway sealing auxiliary accessories and the like. By the adoption of the precision conveying and jacking device with the multi-dimensional angle adjustment function, different falling speedscan be realized, the working efficiency and reliability can be improved, the angle adjustment of a mounted object in three different dimensions can be realized, and the precision fine adjustment of the conveying and jacking distance of the mounted object in the vertical direction can be realized.

Description

technical field [0001] The invention is suitable for ceiling-feeding installation in scenarios where the spatial reference is complex and changeable, and internal and external splines require high matching 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 positions of the aeroengine pump adjustment accessories are also variable. 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, which need to be met on the one hand The coordination of the inner and outer spline shafts, on the other hand, is constrained by the installation of positioning pins; 4. The product is i...

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, which need to be met on the one hand 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
