Description

Technical Field

[0001] The invention relates to the technical field of precision assembly of gyroscope moving coil assemblies, and in particular to a forming and assembling device and an assembling method of a gyroscope moving coil assembly. Background Art

[0002] Gyroscopes (hereafter referred to as gyros) are widely used in satellites, spacecraft, space stations and other fields due to their high precision, long life and high reliability, providing reliable navigation parameters for the carriers.

[0003] At present, the semi-liquid floating gyroscopes, liquid floating gyroscopes, two-floating gyroscopes and three-floating gyroscopes designed and produced in China all have torquers and sensors. The torquer is the feedback measurement element in the servo closed-loop system of the inertial device. It generates the necessary torque or balancing torque on the rotor and inertial mass pendulum of the gyroscope; the sensor is the element that converts the mechanical angle of the rotating shaft relative to the frame into voltage. The dynamic coil assembly is an important component of the torquer and sensor. Its assembly technology is difficult. The angle and position of the coil in the assembly determine the accuracy of the gyroscope, and the accuracy of the gyroscope determines the accuracy of the entire inertial device.

[0004] When bonding the coils of the moving coil assembly, the angular position tolerance between the coils is required to be within ±15', and after the coils are bonded, they have higher dimensional requirements with the outer circle of the moving coil bracket. The coil itself is a frameless structure and is easily deformed during bonding. The shape of the coil needs to be fixed during the bonding process. If the coil is directly assembled without auxiliary devices, it is impossible to achieve such high precision requirements, and the size of the assembly formed by the coil assembly will also be out of tolerance. Therefore, it is necessary to design a coil forming and assembly device to ensure the technical requirements of product assembly.

[0005] The existing moving coil assembly assembly method usually forms the wound coil first, and the curvature of the coil is consistent with the outer circle of the moving coil bracket to facilitate subsequent bonding; then, according to the angle requirements and axial position of the coil bonding distribution, the coil bonding position is marked in advance on the outer circle of the moving coil, and the 8 formed coils are bonded to the outer circle of the moving coil bracket in sequence according to the marked position; then, the bonded coil is shaped and cured with a hoop-type tooling, and after the coil and the moving coil bracket are firmly bonded, the hoop-type tooling is removed; finally, the angle position, axial position, and outer circle size of each coil are measured using detection equipment, and the coil is rewound and bonded for products with unqualified coil bonding positions.

[0006] It can be seen that the existing dynamic assembly assembly method has the following shortcomings: First, the coil assembly qualification rate is low, about 50%. Second, the production cost is high. For products with unqualified coil bonding, the coil needs to be dismantled and scrapped, rewound, bonded, and tested, which increases the cost of raw materials, labor costs, and testing costs. Third, the production cycle is long. Since the unqualified products need to be rewound, bonded, cured, and tested, the production cycle is increased. Summary of the invention

[0045] In order to make the purpose, advantages and features of the present invention clearer, the following is a further detailed description of a forming and assembling device and an assembling method of a gyro moving coil assembly proposed by the present invention in combination with the accompanying drawings and specific embodiments. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0046] The angle, position and size of the coils assembled on the moving coil assembly directly determine the accuracy of the gyroscope. The gyroscope moving coil assembly consists of a moving coil bracket 9 and a plurality of coils. The coils are bonded and fixed to the outer surface of the moving coil bracket 9. The structure of the moving coil bracket 9 is as follows: Fig. 9 As shown, a process handle for positioning is provided at the lower end of the dynamic coil support. There are high angle and position requirements between each coil and between the coil and the dynamic coil support 9 to achieve the accuracy of the angle and position when the coil is bonded.

[0047] like Figure 1 As shown, this embodiment proposes a molding and assembling device for a gyro moving coil assembly coil, including a base 1, a pressure plate 2, a positioning pin 3, a fixed shaft 4, a clamping shaft 5, a clamping sleeve 6, a clamping screw 7 and a countersunk screw 8.

[0048] like Figure 2 As shown in (a) and (b), the base 1 is a cylindrical structure with an opening at the upper end, and a center hole 11 is provided at the center of the bottom surface thereof. An annular groove is provided on the circumference of the center hole 11 for fixing the axial and radial positions of the moving coil support 9, thereby ensuring the coaxiality of the moving coil support 9 and the forming assembly device. The center step surface of the base 1 cooperates with the positioning boss of the moving coil support 9 to limit the radial position of the moving coil support 9; when the positioning boss of the moving coil support 9 is assembled to the center step surface of the base 1, the end face of the moving coil support 9 contacts the center step surface of the base 1 by relying on the gravity of the moving coil support 9 itself, thereby limiting the axial position of the moving coil support 9. Positioning pin 3 (such as Figure 8 The locating pin 3 is installed on the central step surface of the base 1 to fix the circumferential position of the moving coil bracket 9. After the boss of the moving coil bracket 9 is assembled with the central step surface of the base 1, the radial and axial positions of the moving coil bracket 9 are fixed, but the circumferential direction can still be rotated. The function of the locating pin 3 is to limit the circumferential rotation of the moving coil bracket 9.

[0049] The upper side wall of the base 1 is provided with 8 radially arranged and evenly distributed guide grooves 12 for placing the fixed shaft 4. When assembling the fixed shaft 4 coil, the angle and height position between the 8 coils can be determined. Two limit grooves 13 are provided on both sides of the 8 guide grooves 12 at equal intervals to the guide grooves 12 for placing the clamping shaft 5. A mounting screw hole is provided in the middle of the guide grooves 12 separated from each other on the base 1. The axial position of the coil of the moving coil assembly to be formed and assembled is designed according to the axial height requirement, and the number and distribution angle of the guide grooves 12 can also be designed according to the requirements of the moving coil assembly to be formed and assembled.

[0050] like Figure 3 As shown in (a) and (b), the pressure plate 2 is a circular ring table, and its outer diameter is slightly larger than the outer diameter of the base 1. The upper surface of the pressure plate 2 is provided with mounting holes in the same position and quantity as the mounting screw holes. The base 1 and the pressure plate 2 are fixedly connected by countersunk screws 8, which are used to fix the clamping shaft 5 and the fixed shaft 4 to prevent the clamping shaft 5 and the fixed shaft 4 from falling off from the upper end surface of the base 2. The lower surface of the pressure plate 2 is provided with a shallow groove 21 at a position corresponding to the limit groove 13, which is used to clamp the upper edge of the clamping shaft 5 to ensure that the clamping shaft 5 does not move left and right. The upper surface of the pressure plate 2 is provided with a screw hole corresponding to each shallow groove 21, which is used to install the clamping screw 7 (such as Figure 7 As shown), it abuts against the upper edge of the clamping shaft 5. After the clamping screw 7 is tightened, the end face of the clamping screw 7 is pressed against the upper edge of the clamping shaft 5 to lock it, fix the position of the clamping shaft 5, and ensure that the clamping shaft 5 does not move.

[0051] like Figure 4 As shown in (a) and (b), the fixed shaft 4 is in the shape of a long strip, and the end against the outer circle of the moving coil bracket 9 is defined as the front end, the width of the front end is greater than the rear end, and the front end surface is an arc surface, the radius of the arc is the same as the radius of the central step surface of the base 1, and is used to match the outer circle of the moving coil bracket 9. A handle groove is provided on the upper surface of the rear end to facilitate pushing the fixed shaft 4 to move forward and backward in the guide groove 12.

[0052] like Figure 5 As shown in (a) and (b), the clamping shaft 5 is a gate-shaped bracket, and its front end is abutted against the edge of the clamping sleeve 6. The front end is provided with opposing protrusions to increase the area abutting against the clamping sleeve 6, which is used to further clamp and fix the sleeve 6. At the same time, the front end is provided with a downward boss. When the clamping shaft 5 is pulled backward, the downward boss at the front end abuts against the inner side surface of the base 1, so that the clamping shaft 5 does not leave the limiting groove 13.

[0053] like Figure 6 As shown in (a) and (b), the front end of the clamping sleeve 6 has the same radius as the center step surface of the base 1. The clamping sleeve 6 is fixedly assembled with the fixed shaft 4. The front end of the fixed shaft 4 is located in the clamping sleeve 6. It is used to shape and clamp the coil during the bonding and curing process of the coil to ensure the coaxiality of the coil and the moving coil. Since the thickness of each coil is consistent, the outer circle of the coil and the moving coil bracket 9 are completely fitted by the clamping sleeve 6. After the coil and the moving coil bracket 9 are completely fitted, the outer circle of the coil finally formed is coaxial with the inner hole of the moving coil.

[0054] The specific steps of bonding the coil of the moving coil assembly using the molding and assembly device of the gyro moving coil assembly are as follows:

[0055] 1. Place the moving coil bracket 9 with its handle facing downward in the center hole 11 of the base 1, ensuring that the lower end surface of the moving coil fits the upper end surface of the center hole of the base 1. Use the positioning pin 3 to pass through the small hole on the lower end surface of the moving coil bracket 9 and fix it in the small hole on the end surface of the base 1. At this time, the axial, radial and axial positions of the moving coil bracket 9 are all fixed to prevent the moving coil bracket 9 from rotating;

[0056] 2. Apply a layer of adhesive glue evenly on the bonding part of the outer circle of the dynamic coil bracket 9, assemble the 8 coils that have been wound in advance on the front ends of the 8 fixed shafts 4, and push the fixed shafts 4 toward the center along the guide grooves 12 on the base 1, so that the front ends of the fixed shafts 4 are completely fitted with the outer circle of the dynamic coil bracket 9;

[0057] 3. Use the clamping shaft 5 to push the clamping sleeve 6 to make the coil fit the outer circle of the moving coil bracket 9. Fig.10 and Fig.11As shown, tighten the clamping screw 7 on the clamping plate 2 so that the end face of the clamping screw 7 presses the clamping shaft 5, thereby ensuring that the clamping sleeve 6 does not move, and the coil and the outer circle of the moving coil bracket 9 are firmly fitted. At this time, the fixed shaft 4 is withdrawn from the clamping sleeve 6;

[0058] 4. Place the molding assembly device together with the moving coil assembly to be bonded in an oven. After the glue solidifies, loosen the clamping screw 7, the clamping shaft 5, and the clamping sleeve 6 in sequence, take out the bonded moving coil assembly, and the entire bonding and assembly process is completed.

[0059] Currently, qualified moving coil assemblies have been assembled in multiple models, including three-float, two-float, liquid-float, and semi-liquid-float models. After system verification, they fully meet the use requirements of the system models.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the present invention.
