Abstract
The utility model belongs to the field of aeronautical instruments and particularly relates to a bonding device meeting requirements for coaxiality of coils and a rotating shaft. The bonding device comprises a long tightening screw and a short tightening screw, wherein the long tightening screw is connected with a positioning column in a threaded mode and penetrates through the positioning column. The inner coil to be bonded and the outer coil to be bonded are arranged on a middle semi-circular column of the positioning column, the positioning column is sleeved with a positioning ring, and the inner coil and the outer coil are embedded into a ring groove of the positioning ring. The inner coil and the outer coil are placed on the middle semi-circular column of the positioning column flat, the positioning column is sleeved with the positioning ring, and the positioning ring groove in the positioning ring guarantees coaxiality of the rotating center of the inner coil and outer coil and the center of the positioning column and a certain included angle between the inner coil and the outer coil crossing with the inner coil; in order to prevent the inner coil and the outer coil from moving along the positioning column in the axial direction, the positioning ring is fixed through a positioning screw.
Description
Technical field
The utility model belongs to aircraft instrument field, is specifically related to a kind of adhering device that guarantees coil and the requirement of rotating shaft coaxle degree.
Background technique
Conventionally moving-coil structure logolmeter, have advantages of highly sensitive, volume is little, two coils intersections form an angle, two moving-coils by electric current are under permanent sinusoidal air gap magnetic fields, produce the contrary moment of both direction, moving-coil is rotated, and the angle of yaw of moving-coil converts the deflection angle of pointer to through logolmeter enlarger.
At present, during the combination of logolmeter movable coil is manufactured, in interior loop, enameled cable is wound on skeleton, and exterior loop is wound on moulding in the demoulding and forms, gluing with J-150 between inner-outer coil and the combination of upper and lower axle.Because inner-outer coil is yielding, when with upper axle combination bonding, there is concentricity tolerance, when with lower shaft combination bonding, also there is concentricity tolerance, both stacks, make concentricity tolerance requirement between upper and lower axle combination and inner-outer coil be difficult to be guaranteed.Due to the existence of concentricity tolerance, when movable coil combination is rotated, produce friction torque and cause that logolmeter indication is sluggish; The static balancing of movable coil combination is simultaneously destroyed, makes logolmeter indicating positions error overproof.
Summary of the invention
The purpose of this utility model is: propose a kind of simple to operate, prevent the adhering device that distortion, the high assurance coil of reliability and rotating shaft coaxle degree require.
The technical solution of the utility model is: a kind of adhering device that guarantees coil and the requirement of rotating shaft coaxle degree, comprise the long fastening screw trip bolt 1 and the short fastening screw trip bolt 5 that are threaded with locating column 2 and penetrate locating column 2, treat that bonding inner-outer coil is placed on the middle semicolumn of locating column 2, positioning ring 3 is enclosed within on locating column 2, inner-outer coil is nested in the annular groove of positioning ring 3, positioning screwn 4 is fixed on positioning ring 3 on locating column 2, treat that bonding upper axle combination is placed between the long fastening screw trip bolt 1 of locating column 2, treat that bonding lower shaft combination is placed between the short fastening screw trip bolt 5 of locating column 2.
Long fastening screw trip bolt 1 and short fastening screw trip bolt 5 axle the preceding paragraphs are screw thread, and one section is optical axis, treat that bonding upper axle combination is placed between the long fastening screw trip bolt 1 of locating column 2, treat that bonding lower shaft combination is placed between the short fastening screw trip bolt 5 of locating column 2.
The utility model has the advantages that: the utility model lies in inner-outer coil on the middle semicolumn of locating column, positioning ring is enclosed within on locating column, positioning ring groove on positioning ring guarantees that the rotating center of inner-outer coil and the center of locating column are coaxial on the one hand, making on the other hand inner-outer coil intersect forms an angle, for preventing that inner-outer coil from moving axially along locating column, fixes positioning ring by positioning screwn.Respectively upper and lower axle combination is compressed to bonding with inner-outer coil by long fastening screw trip bolt and short fastening screw trip bolt, long fastening screw trip bolt and short fastening screw trip bolt axle the preceding paragraph are screw thread, one section is optical axis, prevent that inner-outer coil is along running shaft distortion axially and radially, upper and lower axle combination axis is overlapped with inner-outer coil spin axis, guarantee coil and the requirement of rotating shaft coaxle degree.This device adopts general utility tool to operate, and simple to operate; Can prevent inner-outer coil and upper and lower axle combination bonding time, along running shaft distortion axially and radially, coil and the requirement of rotating shaft coaxle degree are guaranteed.
