Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0034] Example 1

[0035] To accommodate laser gyroscope resonators of various sizes and shapes during batch inspection, this embodiment provides a fixture for batch inspection of laser gyroscope resonators. (See attached image.) Figure 1 , Figure 2The system includes a base 1 and a support member 2; at least one support member 2 is installed on the base 1. To facilitate inspection, the support members 2 on the base 1 are spaced apart to reduce inspection errors.

[0036] The support member 2 is equipped with a locking assembly 3, which locks the laser gyroscope resonator 4 placed on the support member 2. Each support member 2 is equipped with one laser gyroscope resonator 4. It should be noted that the structure and size of the laser gyroscope resonator 4 installed on each support member 2 are selected according to actual needs, and therefore, they can be different or the same. That is, laser gyroscope resonators 4 of different sizes and shapes can be fixed on the same base 1, which improves the compatibility and working efficiency of the tooling.

[0037] For example, the base 1 can be one of the shapes such as rectangle, square, or circle.

[0038] In the specific implementation process, see Figure 1 , Figure 2 The carrier 2 includes a mounting plate 21 and a first positioning member 22. The mounting plate 21 is mounted on the base 1, and the first positioning member 22 is vertically disposed on the upper end face of the mounting plate 21. The inner side wall of the first positioning member 22 abuts against the outer side wall of the laser gyroscope resonant cavity 4. The locking assembly 3 is disposed on the mounting plate 21 and locks the outer side wall B of the laser gyroscope resonant cavity 4. That is, during installation, the outer side wall A of the laser gyroscope resonant cavity 4 can be first placed against the inner wall of the first positioning member 22, and then the outer side wall B of the laser gyroscope resonant cavity 4 can be locked by the locking assembly 3.

[0039] It should be noted that when the laser gyroscope resonant cavity 4 has a polygonal structure, in order to improve stability, at least one of the first positioning member 22 and the locking assembly 3 is provided. For example, when there are two first positioning members 22, the inner sidewalls of the two first positioning members 22 abut against two adjacent outer sidewalls of the laser gyroscope resonant cavity 4 to be tested; for example, when the laser gyroscope resonant cavity 4 has an octagonal structure, two of the first positioning members 22 and the locking assembly 3 are provided, and in four different directions; that is, two adjacent surfaces of the laser gyroscope resonant cavity 4 abut against the inner sidewalls of the two first positioning members 22 respectively, and the other two surfaces of the laser gyroscope resonant cavity 4 are locked by one of the locking assemblies 3 respectively, so as to fix the laser gyroscope resonant cavity 4 in the receiving cavity enclosed by the mounting plate 21, the first positioning member 22, and the locking assembly 3.

[0040] For example, the first positioning element 22 is located at the edge of the mounting plate 21 and is integrally formed with the mounting plate 21, thereby expanding the installation capacity of the bearing element 2; at least one first positioning element 22 is provided on each mounting plate 21 and they are spaced apart to abut against different outer walls of the laser gyroscope resonant cavity 4, thereby improving the stability of the laser gyroscope resonant cavity 4 and thus improving the inspection accuracy.

[0041] For example, there are several carriers 2, which are installed in an array on the base 1 for easy inspection.

[0042] To facilitate installation without compromising aesthetics, the mounting plate 21 has at least one countersunk hole 211. The insertion end of a connector (not labeled in the figure) passes through the countersunk hole 211 and is then inserted into the mounting hole 11 on the base 1 to fix the mounting plate 21 to the base 1. That is, the countersunk hole 211 corresponds to the mounting hole 11 on the base 1. For example, if the connector is a countersunk screw, the nut of the countersunk screw is located in the countersunk hole 211.

[0043] The base 1 has a plurality of regularly arranged mounting holes 11 for batch mounting of the carrier 2, thereby achieving the purpose of batch testing of the laser gyroscope resonant cavity 4. For example, the mounting holes 11 are spaced out along the base 1.

[0044] In the specific implementation process, see Figure 1 , Figure 2 The locking assembly 3 includes a second positioning member 31 and a locking member 32;

[0045] The second positioning member 31 is vertically disposed on the upper end face of the mounting plate 21, and the second positioning member 31 has a through hole 311 facing the center of the mounting plate 21;

[0046] The locking member 32 is disposed on the through hole 311, and one end of the locking member 32 facing the center of the mounting plate 21 abuts against the outer wall B of the laser gyroscope resonant cavity 4. It should be noted that the depth of the locking member 32 extending into the center of the mounting plate 21 can be selected according to the shape and size of the laser gyroscope resonant cavity 4 so as to abut against the outer wall B of the laser gyroscope resonant cavity 4. If there are two second positioning members 31, the two locking members 32 can abut against different outer walls of the laser gyroscope resonant cavity 4, such as outer wall B1 and outer wall B2.

[0047] For example, the locking element 32 is a screw, and the through hole 311 is a threaded hole. Therefore, the depth to which the screw is screwed into the mounting plate 21 in space can be determined according to the size, shape, etc. of the laser gyroscope resonant cavity 4 to be tested.

[0048] This utility model is implemented as follows:

[0049] The laser gyroscope resonant cavity 4 to be tested is placed on the mounting plate 21, and part of the outer wall of the laser gyroscope resonant cavity 4 is tightly attached to the first positioning member 22 to prevent the laser gyroscope resonant cavity 4 from tilting or shaking during the testing process.

[0050] Then adjust the distance between the locking member 32 and the laser gyroscope resonant cavity 4 so that the working section of the locking member 32 abuts against the outer wall of the laser gyroscope resonant cavity 4, so that the laser gyroscope resonant cavity 4 is fixed to the carrier member 2, and then subsequent inspection operations can be carried out.

[0051] When it is necessary to replace the laser gyroscope resonant cavity 4 with one of different sizes, simply adjust the distance by which the locking member 32 is screwed into the center of the mounting plate 21. Of course, if the size of the laser gyroscope resonant cavity 4 is too large, a larger mounting plate 21 can also be used, and the subsequent installation and inspection operations are the same.

[0052] This embodiment has a simple structure, enabling batch testing of laser gyroscope resonators while being compatible with laser gyroscope resonators of different sizes and shapes, thus improving testing accuracy and efficiency.

[0053] It should be noted that the descriptions of each embodiment in the above embodiments have different focuses. For parts that are not described in detail in a certain embodiment, please refer to the relevant descriptions in other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.

[0055] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
