Description

Technical Field

[0001] The invention relates to a liquid-floating gyroscope assembly and disassembly tool and method, and in particular to a liquid-floating gyroscope assembly and disassembly auxiliary device, and an assembly and disassembly method. Background Art

[0002] Liquid-floating gyroscopes are widely used in aerospace, aviation and other fields due to their anti-vibration, impact resistance and high reliability. They are sensitive devices for measuring the pitch, yaw and roll angular velocity of aerospace, aircraft and projectiles, and play an important role in inertial navigation and guidance systems. Due to the high-precision requirements of liquid-floating gyroscopes, most of the liquid-floating gyroscope parts are small in size, high in machining accuracy and small in fit size. The machining, inspection and assembly accuracy of some parts are within the range of precision or ultra-precision machining accuracy. The form and position tolerances and fit tolerances of the parts are all at the micron level, resulting in a high production cost for liquid-floating gyroscopes.

[0003] When designing the structure of the liquid-floating gyroscope, the shell of the liquid-floating gyroscope is made of iron-nickel soft magnetic alloy material, which serves as the overall support and installation structure, and also as the outer magnetic ring of the torquer, forming a closed-loop magnetic field together with the torquer stator. Figure 1 The liquid-floating gyroscope shell 01 is divided into a left end and a right end by the flange ring 011, which are used to assemble the sensor seat assembly 02 and the torquer seat assembly 03 respectively. The float 04 is located in the middle of the liquid-floating gyroscope shell 01, and the inflation nozzle of the float 04 is facing the mounting hole on the sensor seat 021. The left end bearing seat assembly 06 and the right end bearing are respectively arranged on the sensor seat 021 and the torquer seat 031. The bellows seat assembly 05 is provided on the left side of the sensor seat assembly 02.

[0004] During assembly, maintenance, and disassembly, the torquer seat assembly 03 is subject to magnetic attraction and can collide with the liquid-floating gyro housing, damaging its magnetic properties and causing the gyro's scale factor to deviate from tolerance. Since the minimum clearance between the gyro float (between the shaft tip and the jewel bearing) is 4μm and the maximum clearance (between the outer diameter of the moving coil assembly and the inner cavity of the liquid-floating gyro housing) is 0.3mm, debris generated by the collision entering any operating part will hinder the normal operation of the float, generating abnormal friction torque and causing the gyro's accuracy to deviate. Furthermore, due to magnetic attraction, the torquer seat and the inner cavity of the liquid-floating gyro housing have a 5μm fit. If the torquer seat assembly 03 is not properly installed during assembly, the gyro's rate scale factor will be affected, causing the rate scale factor to deviate from tolerance.

[0005] When designing the structure of the liquid-floating gyroscope, the clearance between the sensor seat and the inner cavity of the liquid-floating gyroscope shell is 4.5μm. The outer circle of the sensor seat Ф35.6 has a long stroke when installed into the inner cavity of the liquid-floating gyroscope shell. If the sensor seat assembly 02 cannot be installed correctly, the float inflation nozzle matches the mounting hole on the sensor seat, and the dynamic coil assembly is installed on the float, it may cause the dynamic coil assembly and the torquer stator to be misaligned, affecting the liquid-floating gyroscope torquer coefficient and causing the rate scale factor to be out of tolerance.

[0006] The problems and shortcomings in the assembly and disassembly process of existing liquid-floating gyroscopes are as follows:

[0007] (1) When the torquer seat assembly 03 is installed into the liquid-floating gyro housing or repaired and reworked, it is easy to cause the magnetic steel to collide due to the influence of magnetic properties, resulting in magnetic damage or excess material problems;

[0008] (2) If excess material is produced, it will cause the accuracy of the liquid floating gyroscope to decrease or even fail;

[0009] (3) If the magnetic properties are damaged, the torquer coefficient decreases, causing the rate scale factor of the liquid-floating gyro to exceed the tolerance;

[0010] (4) The clearance between the torquer seat and the liquid-floating gyro housing is small. Under the influence of magnetic properties, the torquer seat assembly 03 is not easy to install correctly, causing the liquid-floating gyro rate scale factor to be out of tolerance;

[0011] (5) The clearance between the sensor seat and the liquid-floating gyro housing is small, and the installation stroke is long. If the sensor seat assembly 02 cannot be installed correctly, the liquid-floating gyro rate scale factor will be out of tolerance. Summary of the Invention

[0012] The present invention aims to solve the problems of the existing liquid-floating gyroscope assembly and disassembly process, which are easily affected by magnetic properties and cause magnetic steel to collide, resulting in magnetic damage or excess materials, and the problem that the torquer seat assembly and sensor seat assembly are difficult to assemble properly due to small fitting clearance, thereby causing the liquid-floating gyroscope rate scale factor to exceed the tolerance.

[0062] A method for assembling and disassembling a liquid-floating gyroscope, using the above-mentioned auxiliary device for assembling and disassembling a liquid-floating gyroscope;

[0063] The assembly method of the liquid-floating gyroscope comprises the following steps:

[0064] Step A1, assembling the torquer seat assembly 03 through the magnetic isolation guide 1;

[0065] Insert the magnetic isolation guide 1 from the left end of the liquid-floating gyroscope shell 01, and then install the torquer seat assembly 03 from the right end of the liquid-floating gyroscope shell 01 inside the liquid-floating gyroscope shell 01. Due to the obstruction of the magnetic isolation guide 1, the torquer stator cannot form a closed-loop magnetic circuit with the liquid-floating gyroscope shell 01, and will not collide with the torquer seat assembly 03; by rotating the torquer seat assembly 03 for adaptive centering, align the engraved line of the torquer seat 031 with the engraved line of the right end of the liquid-floating gyroscope shell 01; after removing the magnetic isolation guide 1, fix it with glue, and then install the float 04 to complete the assembly of the torquer seat assembly 03;

[0066] Step A2, assembling the sensor seat assembly 02;

[0067] Use three long screws to screw into the mounting holes of the sensor base 021. Hold the heads of the three long screws and install the sensor base assembly 02 into the inner cavity of the liquid-floating gyroscope shell 01. Align the float inflation nozzle with the mounting hole of the sensor base 021. Use the float 04 inflation nozzle to limit the position of the sensor base 021. Fine-tune the adaptive centering of the sensor base 021 to align the engraved line of the sensor base with the engraved line on the left end of the liquid-floating gyroscope shell 01. Fix it with glue to complete the assembly of the sensor base assembly 02.

[0068] The disassembly method of the liquid-floating gyroscope comprises the following steps:

[0069] Step B1: Use mechanical processing to remove the right end cover of the liquid-floating gyroscope housing 01 and the welding seal structure between the bellows assembly 05 and the liquid-floating gyroscope housing 01;

[0071] After step B1 is completed, the inner cavity of the liquid-floating gyroscope shell 01 is sealed with a thin layer of solder, so the liquid-floating gyroscope shell 01 will not be damaged, and the magnetic properties will not be damaged. In addition, the right end cover of the liquid-floating gyroscope shell 01 and the bellows assembly 05 have relatively low manufacturing costs, and the rework and scrapping costs are small.

[0072] Step B2, refer to Figure 17 , dismantle the sensor seat assembly 02 using the first dismantling auxiliary device;

[0073] After taking out the bellows assembly from one end of the liquid-floating gyro housing 01, remove the nut and bearing seat assembly 06, and clean the glue on the end surface of the gap between the sensor seat 021 and the liquid-floating gyro housing 01;

[0074] Use screws to fix the sensor base transition piece 2 to the end face of the sensor base. Install the spacer 3 and the first pressure plate 4 in sequence. Pass the screw 5 through the third center threaded hole, the second center through hole, and the first center through hole in sequence, and fix it to the threaded hole of the sensor base 021. Press the sensor base transition piece 2 tightly against the end face of the sensor base 021.

[0075] The wrench is passed through the radial slot 41 of the first pressure plate 4, and the first pressure plate 4 is rotated. The screw 5 moves upward, driving the sensor seat 021 upward, thereby removing the sensor seat assembly 02 from the liquid-floating gyro housing 01. Finally, the sensor seat assembly 02 is removed from the first disassembly auxiliary device, completing the disassembly of the sensor seat assembly 02.

[0076] Step B3, refer to Figure 18 , dismantle the torquer seat assembly 03 through the second dismantling auxiliary device;

[0077] After taking out the float 04 from the left end of the liquid-floating gyroscope shell 01, remove the glue on the end surface of the gap between the torquer seat 031 and the liquid-floating gyroscope shell 01; install the magnetic isolation guide 1 from the left end of the liquid-floating gyroscope shell 01, and put the sleeve 6 on the liquid-floating gyroscope shell 01, and apply pressure to the flange ring 011 on the liquid-floating gyroscope shell 01 through the second pressure plate 7 and the sleeve 6 (direction as shown in FIG. Figure 18 As shown by the arrow in the middle, the torquer seat assembly 03 is pushed out from the right end of the liquid-floating gyroscope housing 01 by the magnetic isolation guide 1, the second pressure plate 7 and the sleeve 6 are removed, and the torquer seat assembly 03 is taken out from the magnetic isolation guide 1 to complete the disassembly of the torquer seat assembly 03.
