Abstract
The utility model relates to a dynamically tuned gyroscope. The dynamically tuned gyroscope comprises a base, a signal coil, a magnet core and a wiring board, wherein a groove provided with a groove bottom surface is formed in the base; the magnet core is inserted into the groove and is fixedly arranged on the groove bottom surface; the part, higher than the groove edge surface of the groove, of the magnet core is sleeved with the signal coil; the wiring board is fixedly arranged on the base. According to the dynamically tuned gyroscope, a foundation seat of a conventional signal device is removed, the groove with the groove bottom surface is directly formed in the base, and the groove bottom surface serves as a weight support surface of the magnet core, so that not only is the axial size of the gyroscope reduced by the structure, but also the weight of the gyroscope is lightened; moreover, the position of the signal device is not required to be captured by manually measuring the end surface of the signal device by using a dial indicator, so that the mounting accuracy of the signal device is improved, and the reliability is high. The screwing is replaced by gluing, and the gyroscope is not required to be adjusted relative to the benchmark of the gyroscope, so that the measurement accuracy of the gyroscope is improved.
Description
Technical field
The utility model relates to a kind of dynamically tuned gyro, DTG.
Background technology
The signalling means of dynamically tuned gyro, DTG is for experiencing gyrorotor with respect to the corner of gyro housing, signalling means is a vitals of dynamically tuned gyro, DTG, the height direct relation of the quality of signalling means and installation accuracy the measuring accuracy of gyroscope integral body, so signalling means is particularly important with regard to what show.As shown in Figure 1, dynamically tuned gyro, DTG comprises gyroscope base 4 and signalling means part, signalling means partly comprises signalling means pedestal 5, magnetic core 1 and terminal block 3, signalling means pedestal 5 is provided with groove, magnetic core inserts groove take base as weight supporting surface, magnetic core is higher than the sheathed signalling means coil of part of groove surface, whole signalling means parts are fixed together with 4 screws 6 and gyroscope base 4, in connection procedure, pass through signalling means pedestal 5 as adaptor, by the method for clock gauge manual measurement signalling means end face, find the position of signalling means accurately, such mounting means installation accuracy is low, before and after screw-driving, signalling means position easily changes, directly affect gyrostatic measuring accuracy, and such mounting means makes axis of gyroscope to longer dimension, be unfavorable for gyrostatic miniaturization.
Utility model content
The purpose of this utility model is to provide a kind of dynamically tuned gyro, DTG, to solve the problem that signalling means installation accuracy is low, gyroscope axial dimension is long of existing dynamically tuned gyro, DTG.
For achieving the above object, dynamically tuned gyro, DTG of the present utility model comprises base, signalling means coil, magnetic core and terminal block, on described base, offer the groove with groove bottom, magnetic core inserts groove and is fixedly arranged in groove bottom, magnetic core is the sheathed described signalling means coil of part along face higher than groove groove, and described terminal block is fixedly arranged on base.
Described terminal block is gluing on base.
Described magnetic core is gluing in groove bottom.
A kind of dynamically tuned gyro, DTG of the present utility model, removed the pedestal of classical signal device, directly on base, process the groove with groove bottom, using the weight supporting surface of groove bottom as magnetic core, this structure has not only reduced gyroscope axial dimension, has alleviated gyrostatic weight, and without find the position of signalling means accurately with clock gauge manual measurement signalling means end face, the installation accuracy that has improved signalling means, reliability is high.Adopt gluing substitute be spirally connected, without more relatively gyroscope benchmark adjust, improve gyrostatic measuring accuracy.
Accompanying drawing explanation
Fig. 1 is the signalling means mounting structure schematic diagram of existing dynamically tuned gyro, DTG;
Fig. 2 is the signalling means mounting structure schematic diagram of the utility model embodiment.
Embodiment
As shown in Figure 2, dynamically tuned gyro, DTG comprises base 4, signalling means coil 2, magnetic core 1 and terminal block 3, on base 4, offer the groove with groove bottom, magnetic core 1 inserts groove and is fixedly arranged in groove bottom by adhesive means, magnetic core is the sheathed signalling means coil of part along face higher than groove groove, and terminal block is fixedly arranged on base 4 by adhesive means.
The concrete mounting means of dynamically tuned gyro, DTG is as follows:
(1) magnetic core processing and terminal block are fixed on base with high strength is gluing by the position of Fig. 2, glue-line is smooth without bubble, coats insullac H30-12 on magnetic core and terminal block.
(2) after adhesive curing, take the reference field of base is that benchmark grinds the end face of magnetic core, makes magnetic core end face reach service precision requirement.
(3) the good coil of prior coiling be placed on magnetic core and carefully connected the wire by wiring diagram, guaranteeing that the flow direction of each magnetic core is series connection, lead-in wire is welded on corresponding terminal block solder joint.
(4) coil soaks insullac H30-12, guarantees to be greater than 500M Ω with base insulation resistance.
(5) mounted signalling means base assembly is stablized to processing: low temperature-55 ℃, high temperature+80 ℃, each is incubated 3h, circulates 5 times.
This dynamically tuned gyro, DTG has removed the pedestal of classical signal device, directly on base, process the groove with groove bottom, using the weight supporting surface of groove bottom as magnetic core, this structure has not only reduced gyroscope axial dimension, alleviated gyrostatic weight, and without find the position of signalling means accurately with clock gauge manual measurement signalling means end face, having improved the installation accuracy of signalling means, reliability is high.Adopt gluing substitute be spirally connected, without more relatively gyroscope benchmark adjust, improve gyrostatic measuring accuracy.
Claims (3)
1. a dynamically tuned gyro, DTG, comprise base, signalling means coil, magnetic core and terminal block, it is characterized in that: on described base, offer the groove with groove bottom, magnetic core inserts groove and is fixedly arranged in groove bottom, magnetic core is the sheathed described signalling means coil of part along face higher than groove groove, and described terminal block is fixedly arranged on base.
