Description

Technical Field

[0001] The utility model relates to the technical field of inertial navigation, and particularly relates to a mounting structure for a laser gyroscope. Background Art

[0002] A laser gyroscope is a precision sensor that measures rotation by utilizing the optical Sagnac effect and has wide applications in the fields of inertial navigation, positioning and orientation, etc. The main structure of the laser gyroscope is a high-precision ring laser resonator, in which two beams of laser propagate in the clockwise and counterclockwise directions. When the laser gyroscope rotates relative to the inertial space, a frequency difference proportional to the rotational angular velocity will be generated between these two beams of laser. By using this frequency difference, the rotational angular velocity of the laser gyroscope relative to the inertial space can be measured. The main body part of the laser gyroscope is mainly composed of glass materials. When the laser gyroscope is in use, the laser gyroscope body and related circuit boards, wires and other accessories are generally installed in an installation box to form a laser gyroscope for use. The laser gyroscope installation box is usually made of hard alloy materials such as super-hard aluminum, and plays a role in protecting the laser gyroscope body and its accessories in terms of mechanical structure, environmental gas, environmental electromagnetic field, etc.

[0003] The laser gyroscope is installed inside the box body through a dither wheel fixedly connected thereto, and other components such as a circuit board also need to be installed inside the box body. As a result, the gap between the laser gyroscope and the box body is very small. However, the information of the laser gyroscope needs to be introduced into the circuit board or led out of the box body by pasting and welding pieces on the inner side wall of the box body and wiring with leads, thereby making the installation of the existing laser gyroscope difficult. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a mounting structure for a laser gyroscope that is convenient for quick installation and rapid power connection and communication in view of the above deficiencies in the prior art.

[0005] The technical solution adopted to solve the technical problem of the utility model is as follows:

[0006] The utility model provides a mounting structure for a laser gyroscope, which includes a laser gyroscope body, a first adapter board, a second adapter board and an installation box; the laser gyroscope body, the first adapter board and the second adapter board are located inside the installation box and are arranged in sequence along the axial direction of the laser gyroscope body. The first adapter board is fixedly connected to the laser gyroscope body, and the second adapter board is fixedly connected to the installation box.

[0007] A process through hole is formed in the first adapter board, and a first adapter pad and a thimble are arranged on the surface thereof facing the second adapter board. The lead of the laser gyroscope body passes through the process through hole and is electrically connected to the adapter pad.

[0008] On one side of the second adapter board facing the first adapter board, there are second adapter pads and external lead pads. The second adapter pads correspond to and abut against the top pins.

[0009] The mounting box is detachably connected to the dither wheel at the center of the laser gyroscope body.

[0010] Thus, the laser gyroscope body and the first adapter board can be fixedly connected outside the mounting box, and the leads of the laser gyroscope body are passed through the process through holes opened on the first adapter board and then electrically connected to the adapter pads on the first adapter board. Then, the second adapter board is fixed inside the mounting box, and the two assemblies (i.e., the laser gyroscope body and the first adapter board form the first assembly, and the second adapter board and the mounting box form the second assembly) are fixedly connected, so that the quick installation of the laser gyroscope can be completed and the quick electrical connection communication of the laser gyroscope can be realized, avoiding the installation difficulties and insecure welding fixation problems existing in the installation and wiring fixation process, thereby effectively improving the assembly quality and efficiency.

[0011] Since the laser gyroscope body needs to be driven to vibrate by the dither wheel during operation to eliminate the locking phenomenon, in the present utility model, the electrical signals of the laser gyroscope body are transferred to the second adapter board through the first adapter board and the top pins, which not only meets the requirements of quick installation and quick electrical connection communication, but also facilitates the vibration of the laser gyroscope, and can avoid the phenomenon that the leads are loosened due to the vibration of the laser gyroscope body when the electrical signals of the laser gyroscope body are directly led to the second adapter board, resulting in signal interruption.

[0012] Optionally, a boss is provided at the position of the mounting box corresponding to the dither wheel. A first avoidance through hole is opened on the first adapter board, and a second avoidance through hole is opened on the second adapter board. The boss passes through the second avoidance through hole and the first avoidance through hole in sequence and is fixedly connected to the dither wheel.

[0013] Thus, the laser gyroscope body and the first adapter board can be fixedly connected outside the mounting box, and the leads of the laser gyroscope body are passed through the process through holes opened on the first adapter board and then electrically connected to the adapter pads on the first adapter board. Then, the second adapter board is fixed on the side of the mounting box with the boss, and the two assemblies (i.e., the laser gyroscope body and the first adapter board form the first assembly, and the second adapter board and the mounting box form the second assembly) are fixedly connected through the dither wheel and the boss, so that the quick installation of the laser gyroscope can be completed and the quick electrical connection communication of the laser gyroscope can be realized, avoiding the installation difficulties and insecure welding fixation problems existing in the installation and wiring fixation process, thereby effectively improving the assembly quality and efficiency.

[0014] Optionally, to further facilitate the vibration of the laser gyroscope, the top pin is a telescopic top pin.

[0015] Optionally, the telescopic ejector pin includes a welding post, a spring, and a contact head. One end of the welding post is fixed on the first adapter plate, and the other end is provided with a receiving groove. One end of the contact head extends into the receiving groove and is fixedly connected to the welding post, and the other end is used to abut against the second adapter pad. The spring is located in the receiving groove and is compressed between the contact head and the bottom of the receiving groove.

[0016] Optionally, to avoid poor contact between the ejector pin and the second adapter pad during the jitter of the ring laser gyroscope, the second adapter pad is an arc-shaped pad that is recessed toward the installation box and extends circumferentially along the second avoidance through hole. Thus, it adapts to the periodic jitter law of the ring laser gyroscope, and the ejector pin will not come out of the arc-shaped pad.

[0017] Optionally, there are multiple process through holes, which are arranged at a position of the first adapter plate close to the first avoidance through hole and are evenly distributed along the circumference of the first avoidance through hole.

[0018] Optionally, there are multiple groups of ejector pins, each group includes multiple ejector pins. The multiple groups of ejector pins are evenly distributed on the first adapter plate along the circumference of the first avoidance through hole, and the multiple ejector pins in each group are arranged in sequence along the radius of the first avoidance through hole.

[0019] Optionally, the first adapter pad includes a grab card pad, an anode pad, a cathode pad, and a dither wheel pad.

[0020] Optionally, the first adapter plate is adhesively connected to the ring laser gyroscope body.

[0021] Optionally, the second adapter plate and the installation box are connected by a first fastener. The second adapter plate is provided with first threaded through holes at four corner positions, and the corresponding positions on the inner wall of the installation box where there are convex platforms are provided with first threaded blind holes. After the first fastener passes through the first threaded through holes and the first threaded blind holes, the second adapter plate and the installation box are firmly connected.

[0022] Optionally, the dither wheel and the convex platform are connected by a second fastener. The dither wheel is provided with three second threaded through holes evenly distributed along its circumference, and the corresponding positions on the convex platform of the installation box are provided with second threaded blind holes. After the second fastener passes through the second threaded through holes and the second threaded blind holes, the dither wheel and the convex platform are firmly connected, that is, the first assembly formed by the ring laser gyroscope body and the first adapter plate, and the second assembly formed by the second adapter plate and the installation box are firmly connected.

[0023] Beneficial effects:

[0024] The installation structure of the laser gyroscope of the present utility model adopts the "gyroscope component + adapter plate" mode, cancels the original installation method that requires pasting and wiring, and avoids the gap limitation between the housing structure and the laser gyroscope body when installing and fixing the laser gyroscope body and welding. Without changing the original installation dimensions, it is convenient to install and fix the laser gyroscope and can be powered on immediately after installation, thereby improving the convenience and stability of the assembly and inspection process of the laser gyroscope.

[0037] Embodiment 1:

[0038] This embodiment provides a laser gyroscope installation structure with stable structure, simple and convenient installation operation.

[0039] As Figures 1-7 shown, the laser gyroscope installation structure includes a laser gyroscope body 1, a first adapter plate 2, a second adapter plate 3, and an installation box 4; the laser gyroscope body 1, the first adapter plate 2, and the second adapter plate 3 are located inside the installation box 4 and are arranged in sequence along the axial direction of the laser gyroscope body 1. The first adapter plate 2 is fixedly connected to the laser gyroscope body 1, and the second adapter plate 3 is fixedly connected to the installation box 4.

[0040] A process through-hole 21 is formed on the first adapter plate 2, and a first adapter pad and a thimble 22 are provided on the surface facing the second adapter plate 3. The lead of the laser gyroscope body 1 passes through the process through-hole 21 and is electrically connected to the adapter pad.

[0041] On the surface of the second adapter plate 3 facing the first adapter plate 2, a second adapter pad 32 and an external lead pad 33 are provided. The second adapter pad 32 corresponds to and abuts against the thimble 22.

[0042] On the surface of the installation box 4 for installing the second adapter plate 3, a boss 8 is provided that cooperates with the dither wheel 7 at the center position of the laser gyroscope body 1. A first avoidance through-hole 23 is formed on the first adapter plate 2, and a second avoidance through-hole 31 is formed on the second adapter plate 3. The boss 8 passes through the second avoidance through-hole 31 and the first avoidance through-hole 23 in sequence and is fixedly connected to the dither wheel 7.

[0043] Thus, the laser gyroscope body 1 and the first adapter plate 2 can be fixedly connected outside the installation box 4, and the lead of the laser gyroscope body 1 is passed through the process through-hole 21 opened on the first adapter plate 2 and then electrically connected to the adapter pad on the first adapter plate 2. Then, the second adapter plate 3 is fixed on the side of the installation box 4 with a dot platform. Next, the two assemblies (i.e., the laser gyroscope body 1 and the first adapter plate 2 form the first assembly, and the second adapter plate 3 and the installation box 4 form the second assembly) are fixedly connected through the shaking wheel 7 and the boss 8, so as to complete the quick installation of the laser gyroscope and realize the quick power connection and communication of the laser gyroscope, avoiding the problems of difficult installation and insecure welding fixation during the installation and wiring fixation process, thereby effectively improving the assembly quality and efficiency.

[0044] Since the laser gyroscope body 1 needs to be driven to shake by the shaking wheel 7 during operation to eliminate the locking phenomenon, in the present utility model, the electrical signal of the laser gyroscope body 1 is transferred to the second adapter plate 3 through the first adapter plate 2 and the ejector pin 22, which not only meets the requirements of quick installation and quick power connection and communication, but also facilitates the shaking of the laser gyroscope, and can avoid the phenomenon that the lead is loosened due to the shaking of the laser gyroscope body 1 when the electrical signal of the laser gyroscope body 1 is directly led to the second adapter plate 3, resulting in signal interruption.

[0045] In this embodiment, to further facilitate the shaking of the laser gyroscope, the ejector pin 22 is a telescopic ejector pin.

[0046] In this embodiment, the telescopic ejector pin includes a welding post 221, a spring 222, and a contact head 223. One end of the welding post 221 is fixed on the first adapter plate 2, and the other end is provided with a receiving groove 224. One end of the contact head 223 extends into the receiving groove 224 and is fixedly connected to the welding post 221, and the other end is used to abut against the second adapter pad 32. The spring 222 is located in the receiving groove and is compressed between the contact head 223 and the bottom of the receiving groove 224.

[0047] In this embodiment, to avoid the situation that the ejector pin 22 and the second adapter pad 32 are in poor contact during the shaking of the laser gyroscope, the second adapter pad 32 is an arc-shaped pad that is recessed towards the installation box 4 and extends circumferentially along the second avoidance through-hole 31. Thus, it adapts to the periodic shaking law of the laser gyroscope, and the ejector pin 22 will not fall out of the arc-shaped pad.

[0048] In this embodiment, a plurality of process through-holes 21 are provided, and the plurality of process through-holes 21 are arranged at a position of the first adapter plate 2 close to the first avoidance through-hole 23 and are evenly distributed along the circumference of the first avoidance through-hole 23.

[0049] In this embodiment, there are multiple sets of thimbles 22, each set including a plurality of thimbles 22. The multiple sets of thimbles 22 are evenly distributed along the circumferential direction of the first avoidance through-hole 23 on the first adapter plate 2, and the plurality of thimbles 22 in each set are arranged in sequence along the radial direction of the first avoidance through-hole 23.

[0050] In this embodiment, the first adapter pad includes a grasping pad 24, an anode pad 25, a cathode pad 26, and a dither wheel pad 27.

[0051] In this embodiment, the first adapter plate 2 is adhesively connected to the laser gyroscope body 1.

[0052] In this embodiment, the second adapter plate 3 and the mounting box 4 are connected by a first fastener 5. Four corner positions of the second adapter plate 3 are provided with first threaded through-holes 34, and corresponding positions on the inner wall of the mounting box 4 corresponding to the side where the boss 8 is provided are provided with first threaded blind holes 41. After the first fastener 5 passes through the first threaded through-hole 34 and the first threaded blind hole 41, the second adapter plate 3 and the mounting box 4 are firmly connected.

[0053] In this embodiment, the dither wheel 7 and the boss 8 are connected by a second fastener 6. Three second threaded through-holes 71 evenly distributed along the circumferential direction of the dither wheel 7 are provided on the dither wheel 7, and second threaded blind holes 81 corresponding to the boss 8 of the mounting box 4 are provided at corresponding positions. There are also three second fasteners 6. After the second fasteners 6 pass through the corresponding second threaded through-holes 71 and second threaded blind holes 81, the dither wheel 7 and the boss 8 are firmly connected, that is, the first assembly formed by the laser gyroscope body 1 and the first adapter plate 2, and the second assembly formed by the second adapter plate 3 and the mounting box 4 are firmly connected.

[0054] The installation process of the laser gyroscope installation structure in this embodiment is as follows:

[0055] The first adapter plate 2 is fixed to the glass cavity of the laser gyroscope body 1 in a cemented form;

[0056] The first adapter plate 2 is designed with a first adapter pad and a telescopic thimble 22 on it; the purpose of setting the telescopic thimble 22 is to adapt to the jitter of the laser gyroscope.

[0057] The electrical signal input of the laser gyroscope can be transferred to the first adapter plate 2 through the process through-hole 21 of the glass cavity of the gyroscope body. Specifically, the lead of the laser gyroscope body 1 passes through the process through-hole 21 and is electrically connected to the first adapter pad on the first adapter plate 2; after the above transfer, the first adapter plate 2 forms an integral body with the laser gyroscope body 1 and can be firmly fastened to the installation base plate of the installation box 4 by screws;

[0058] In this embodiment, the second adapter plate 3 is designed with a second adapter pad 32 (i.e., an arc pad) and an external lead pad 33, and other encapsulation pads for other requirements can be added;

[0059] To avoid the poor contact between the thimble and the arc-shaped pad during the jitter of the ring laser gyro, the arc-shaped pad is an arc-shaped pad that is recessed towards the installation box and extends circumferentially along the second avoidance hole, so as to adapt to the periodic jitter law of the ring laser gyro, and the thimble will not fall out of the arc-shaped pad.

[0060] In this embodiment, the second adapter board 3 can be fixed on the installation base plate of the installation box by screws;

[0061] In this embodiment, after the ring laser gyro body 1 is bonded to the first adapter board 2, it is assembled with the whole formed by fixing the installation base plate and the second adapter board 3.

[0062] Thus, the ring laser gyro body and the first adapter board 2 can be adhesively connected outside the installation box, and the lead of the ring laser gyro body passes through the process through hole 21 opened on the first adapter board 2 and is electrically connected to the adapter pad on the first adapter board 2. Then, the second adapter board 3 is fixed on the side of the installation base with a boss, and the two assembled bodies (that is, the ring laser gyro body and the first adapter board 2 form the first assembled body, and the second adapter board 3 and the installation base form the second assembled body) are fixedly connected by the jitter wheel and the boss, so that the quick installation of the ring laser gyro can be completed and the quick power connection and communication of the ring laser gyro can be realized, avoiding the problems of difficult installation and insecure welding fixation existing in the installation and wiring fixation processes, thereby effectively improving the assembly quality and efficiency.

[0063] Since the ring laser gyro body needs to be driven by the jitter wheel 7 to jitter during the working process to eliminate the locking phenomenon, in the present utility model, the electrical signal of the ring laser gyro body is transferred to the second adapter board 3 through the first adapter board 2 and the thimble 22, which not only meets the requirements of quick installation and quick power connection and communication, but also facilitates the jitter of the ring laser gyro, and can avoid the phenomenon that the lead is loosened due to the jitter of the ring laser gyro body 1 when the electrical signal of the ring laser gyro body 1 is directly led to the second adapter board 3, resulting in signal interruption.

[0064] Compared with the existing installation and power connection technologies of the ring laser gyro body 1, this utility model can effectively improve the assembly quality and efficiency.

[0065] This structural device can stably realize the quick power connection of the ring laser gyro, and can effectively avoid the problems of insecure welding and fixation during the installation process and wiring fixation process. It effectively improves the assembly quality and efficiency.

[0066] Such as Figure 1, first, turn the side of the first adapter board 2 with the first adapter pads and telescopic thimbles towards the second adapter board 3, and fix the other side of the first adapter board 2 to the glass cavity of the laser gyroscope body 1 in a bonding form. The electrical signal input of the laser gyroscope can be transferred to the first adapter board 2 through the process through-hole 21 of the glass cavity of the gyroscope. The side of the second adapter board 3 facing the first adapter board 2 is designed with arc pads and external lead pads, and other packaging pads for other requirements can be added. The second adapter board 3 can be fixedly installed on the base of the mounting box 4 by screws. After the laser gyroscope body 1 is bonded with the first adapter board 2, it is assembled with the whole body after the mounting base and the second adapter board 3 are fixed, so as to realize the quick installation of the laser gyroscope and the quick electrical connection communication of the laser gyroscope.

[0067] It can be understood that the above embodiments are only exemplary embodiments adopted to illustrate the principle of the present invention, but the present invention is not limited thereto. For those of ordinary skill in the art, various modifications and improvements can be made without departing from the spirit and essence of the present invention, and these modifications and improvements are also regarded as the protection scope of the present invention.
