Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of inertial navigation equipment assembly, in particular to a laser gyro clamping fixture. BACKGROUND

[0002] As a core angular velocity sensor of inertial measurement equipment, the laser gyro is a precision optical device composed of a glass body, which has the characteristics of high value and high precision. The main body is usually a hexahedral structure, and the sensitive optical and electronic components are arranged on the six outer surfaces of the glass body. The effective clamping stress area is extremely limited. At present, the assembly of the laser gyro generally relies on manual operation, and the outer surface is directly gripped for installation.

[0003] With the increasing demand for lightweight and miniaturization of inertial measurement equipment, the sealed installation cavity space for accommodating the laser gyro is greatly compressed. The sealed installation cavity is usually designed as a hexahedral structure with only one open surface. The miniaturization of the equipment directly leads to a sharp reduction in the operating gap between the laser gyro and the inner wall of the sealed installation cavity. Under such extreme space constraints, the traditional manual installation method faces severe challenges. On the one hand, due to the extremely limited operating space, it is difficult for the installer to achieve fast, stable and precise operation in the narrow gap, and the manual gripping method is prone to instability in the limited space, resulting in accidental collision or falling of the high-value laser gyro during installation, causing damage to the precision optical device. On the other hand, the manual gripping method directly contacts the outer surface of the laser gyro, which has the risk of touching or pressing the surface precision components, which may cause contamination and damage to the components. SUMMARY

[0004] The technical problem to be solved by the present application is to overcome the shortcomings of the prior art and provide a laser gyro clamping fixture which is easy to operate, safe and reliable, can reduce pollution and damage, and has good universality.

[0005] To solve the above technical problems, the following technical solutions are adopted: A laser gyro clamping fixture includes a base and a plurality of clamping pieces for inserting into the installation hole of the laser gyro. The plurality of clamping pieces are arranged around a predetermined center line fixed relative to the base. Each clamping piece is installed on the base in a manner that can adjust the distance between the clamping piece and the predetermined center line. The base is provided with an adjusting assembly for adjusting the distance between each clamping piece and the predetermined center line.

[0006] As a further improvement of the above technical solution: The adjusting assembly drives the plurality of clamping pieces to move synchronously towards or away from the predetermined center line.

[0007] The adjustment assembly includes a rotating seat rotatably mounted on a base. Each clamping member is connected to the rotating seat via a connecting rod. One end of the connecting rod is hinged to the clamping member, and the other end of the connecting rod is hinged to the rotating seat. The hinge axis between the connecting rod and the rotating seat is offset from the rotation axis of the rotating seat. The adjustment assembly also includes a drive mechanism for driving the rotating seat to rotate.

[0008] The clamping member includes a slider and a clamping pin fixed to the slider. The slider is slidably mounted on the base in a linear reciprocating motion. The connecting rod is hinged to the slider.

[0009] The base is a plate with a sliding groove. The sliding groove has an opening located at the periphery of the plate. The slider includes a middle part and limiting parts connected to both ends of the middle part. The middle part is inserted into the sliding groove through the opening of the sliding groove, and the two limiting parts are located on both sides of the plate so that the slider slides along the sliding groove to perform linear reciprocating motion. The rotating seat and connecting rod are located on one side of the plate, and the clamping pin is located on the other side of the plate.

[0010] The rotating seat is provided with a transmission shaft connected to the driving mechanism, and the connecting rod is a bent rod with the concave side of the bent rod facing the transmission shaft.

[0011] The clamping pin is equipped with a flexible friction sleeve; the base is provided with marking lines to indicate the sliding position of the slider.

[0012] The drive mechanism includes a worm gear and a turbine gear that cooperate with each other. The worm gear is connected to a rotating handwheel, and the turbine gear is connected to a rotating base.

[0013] The base is detachably connected to an adapter plate, and the base and the adapter plate are spaced apart to form an installation space. The worm and the turbine are mounted on the adapter plate, and the rotating seat and the connecting rod are located in the installation space between the base and the adapter plate.

[0014] The adapter plate is equipped with a handle for easy gripping.

[0015] Compared with the prior art, the advantages of the present invention are as follows: The laser gyroscope clamping fixture of this invention allows for adjustment of the distance between each clamping component and a predetermined center line using an adjusting assembly. This enables multiple clamping components to be inserted into the mounting holes of the laser gyroscope. Further adjustment of the distance between each clamping component and the predetermined center line increases or decreases the distance to clamp the laser gyroscope. The clamped laser gyroscope can then be installed using a holding base. After installation, adjusting the distance between each clamping component and the predetermined center line again allows the clamping components to exit the mounting holes of the laser gyroscope, releasing the laser gyroscope. This design is virtually unrestricted by operating space, facilitating fast, stable, and precise operation. It avoids the problems of accidental collisions or slippage that can damage precision optical components when operating by hand in confined spaces, and prevents component contamination and damage. Furthermore, by adjusting the distance between multiple clamping components and the predetermined center line, the laser gyroscope can be clamped and released, making it suitable for laser gyroscopes with different mounting hole spacings, demonstrating good versatility.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 3As shown, the laser gyroscope clamping fixture of this embodiment includes a base 1 and a plurality of clamping members 2 for inserting into the mounting hole 101 of the laser gyroscope. The plurality of clamping members 2 are arranged around a predetermined center line fixed relative to the base 1. Each clamping member 2 is mounted on the base 1 in a manner that allows adjustment of the distance between it and the predetermined center line. The base 1 is provided with an adjustment component for adjusting the distance between each clamping member 2 and the predetermined center line. This laser gyroscope clamping fixture can adjust the distance between each clamping member 2 and the predetermined center line to a suitable size by adjusting the adjustment component, so that the plurality of clamping members 2 can be inserted into the mounting hole 101 of the laser gyroscope. By increasing or decreasing the distance between each clamping member 2 and the predetermined center line by adjusting the adjustment component, the laser gyroscope can be clamped. Then, by holding the base 1, the clamped laser gyroscope can be installed. After installation, by adjusting the distance between each clamping member 2 and the predetermined center line to a suitable size, the plurality of clamping members 2 can be removed from the mounting hole 101 of the laser gyroscope, and the laser gyroscope can be released. It is virtually unrestricted by operating space, facilitating fast, stable, and precise operation. This avoids the problems associated with hand-held operation in confined spaces, which can easily lead to accidental collisions or slips that could damage precision optical components, and it also prevents contamination and damage to components. Furthermore, by adjusting the distance between multiple clamping members 2 and the predetermined center line, the laser gyroscope can be clamped and released, making it suitable for laser gyroscopes with different spacing mounting holes 101, thus offering good versatility.

[0024] The laser gyroscope in this embodiment has a conventional structure, such as... Figure 5 As shown, it includes a body 102, and a plurality of mounting holes 101 are provided in the middle of the body 102. The plurality of mounting holes 101 are arranged at intervals around a predetermined axis fixed relative to the body 102. By adjusting the distance between each clamping member 2 and the predetermined center line, the plurality of clamping members 2 can be inserted into the plurality of mounting holes 101 respectively, and clamping and releasing the laser gyroscope.

[0025] In this embodiment, optionally, the adjusting component drives multiple clamping elements 2 to move synchronously toward or away from the predetermined center line. That is, the adjusting component drives all clamping elements 2 to move simultaneously toward or away from the predetermined center line. Using only one adjusting component to drive multiple clamping elements 2 simultaneously not only improves the simplicity and compactness of the structure, reduces costs and control difficulty, but also ensures good synchronization of the movements of multiple clamping elements 2, resulting in stable and reliable clamping.

[0026] In this embodiment, optionally, the adjustment assembly includes a rotating seat 3 rotatably mounted on the base 1. The rotation axis of the rotating seat 3 coincides with a predetermined center line. Each clamping member 2 is connected to the rotating seat 3 via a connecting rod 4. One end of the connecting rod 4 is hinged to the clamping member 2, and the other end of the connecting rod 4 is hinged to the rotating seat 3. The hinge axis between the connecting rod 4 and the rotating seat 3 is offset from the rotation axis of the rotating seat 3. The adjustment assembly also includes a drive mechanism for driving the rotating seat 3 to rotate. The drive mechanism drives the rotating seat 3 to rotate in both directions, and the rotating seat 3, along with the connecting rod 4, drives the corresponding clamping member 2 to move, thereby adjusting the distance between the rotating seat 3 and the predetermined center line. This adjustment assembly has the advantages of simple structure, low cost, and easy control.

[0027] In this embodiment, optionally, the clamping member 2 includes a slider 21 and a clamping pin 22 fixed to the slider 21. The slider 21 is slidably mounted on the base 1 in a linear reciprocating motion, and the connecting rod 4 is hinged to the slider 21. The clamping pin 22 is slidably mounted on the base 1 via the slider 21 in a linear reciprocating motion, thereby changing the distance between it and the predetermined center line. Its movement has good stability and accuracy, facilitating precise, stable, and reliable clamping of the laser gyroscope. Preferably, the clamping member 2 is a cylindrical pin.

[0028] In this embodiment, optionally, the base 1 is a plate with a sliding groove 11. The sliding groove 11 has openings located around the perimeter of the plate. The slider 21 includes a middle part 211 and limiting parts 212 connected to both ends of the middle part 211. That is, the slider 21 is I-shaped. The middle part 211 is inserted into the sliding groove 11 through the opening of the sliding groove 11, and the two limiting parts 212 are respectively located on both sides of the plate so that the slider 21 slides along the sliding groove 11 to perform linear reciprocating motion. The rotating seat 3 and the connecting rod 4 are located on one side of the plate, and the clamping pin 22 is located on the other side of the plate. During manufacturing, it is only necessary to first make the sliding groove 11 and the corresponding I-shaped slider 21 on the whole plate, install the clamping member 2 onto the I-shaped slider 21, and then slide the I-shaped slider 21 into the sliding groove 11 to complete the installation of the clamping member 2. It is simple to manufacture and has low cost.

[0029] In this embodiment, optionally, the rotating base 3 is provided with a transmission shaft 31 connected to the driving mechanism, and the connecting rod 4 is a bent rod, with the concave side of the bent rod facing the transmission shaft 31. Preferably, the connecting rod 4 is an L-shaped rod, which allows the clamping member 2 to be closer to the predetermined center line, increasing the range of motion of the clamping member 2, thereby accommodating more mounting holes 101 with different spacings of the laser gyroscope, improving the applicability, and increasing the structural compactness of the fixture.

[0030] In this embodiment, optionally, the clamping pin 22 is fitted with a flexible friction sleeve, which can increase the contact friction with the inner wall of the mounting hole 101 on the laser gyroscope, improve the clamping stability and reliability, and avoid damage to the inner surface of the mounting hole 101; preferably, the flexible friction sleeve is made of rubber. The base 1 is provided with a marking line 12 for indicating the sliding position of the slider 21, which facilitates observation and adjustment of the basic position of the clamping pin 22 to quickly clamp laser gyroscopes with mounting holes 101 at different spacings.

[0031] In this embodiment, optionally, as follows: Figure 3 and Figure 4 As shown, the drive mechanism includes a worm gear 23 and a turbine gear 24 that cooperate with each other. The worm gear 23 is connected to a rotating handwheel 25, and the turbine gear 24 is connected to a rotating seat 3. Rotating the rotating handwheel 25 rotates the worm gear 23, which in turn drives the turbine gear 24 and the rotating seat 3 connected to the turbine gear 24 to rotate, thus achieving infinitely adjustable position of the clamping member 2. The cooperation between the worm gear 23 and the turbine gear 24 has a self-locking function, which can maintain the clamping member 2 stably and reliably without additional mechanisms, preventing it from falling off due to reduced clamping force. In other embodiments, the drive mechanism can also take other forms, such as a motor, as long as it can drive the rotating seat 3 to rotate.

[0032] In this embodiment, optionally, the base 1 is detachably connected to the adapter plate 5. The base 1 and the adapter plate 5 are spaced apart to form an installation space. The worm gear 23 and the turbine gear 24 are mounted on the adapter plate 5, and the rotating seat 3 and the connecting rod 4 are located within the installation space between the base 1 and the adapter plate 5. Specifically, the base 1 is provided with multiple protrusions, and the adapter plate 5 is fastened to the multiple protrusions with screws, thereby forming the installation space.

[0033] In this embodiment, optionally, the adapter plate 5 is provided with a handle 51 for easy gripping, so as to facilitate gripping the base 1.

[0034] The above description is merely a preferred embodiment of the present invention, and the scope of protection of the present invention is not limited to the above embodiments. For those skilled in the art, improvements and modifications obtained without departing from the inventive concept should also be considered within the scope of protection of the present invention.
