Description

Technical Field

[0001] The present invention relates to the field of mechanical transmission, and more specifically, to an elevation-azimuth marching fixator for a remotely controlled turret. Background Art

[0002] The marching fixator is mainly used to lock the frame of the weapon system during marching, so as to fix the lifting part and the slewing part of the weapon system. The weapon system equipped with the marching fixator can effectively prevent damage to the system vertical axis, elevation mechanism, balance mechanism, traverse mechanism and other frame structures caused by marching vibration and impact. In weapon systems, remotely controlled turrets are increasingly widely used. They have many advantages such as remote control and precise strike, and can effectively ensure personnel safety and complete combat missions in complex and changeable battlefield environments. As a key component to ensure the stable and safe transportation of the remotely controlled turret during marching, the marching fixator plays a crucial role and faces a series of strict requirements.

[0003] On military vehicles, remotely controlled turrets are installed on the carrier platform, generally including column slewing type, bracket slewing type and tripod type. In the existing bracket slewing type turrets, the marching fixator is divided into an elevation marching fixator and an azimuth marching fixator, and is generally manually operated. However, in remotely controlled turrets, when the marching fixator switches between the marching state and the combat state, its operation should be mechanized or automated to ensure quick action, meeting both the requirements of unmanned operation and the requirements of elevation and azimuth fixation at the same time. In addition, on the premise of meeting the above requirements, the marching fixator should be as simple and portable as possible. Existing marching fixators often use heavy materials to pursue high strength, and the structural layout is not fully optimized in design, resulting in a large volume and overweight. When installing and disassembling, it relies on a large number of bolts and nuts for fastening, which is time-consuming and laborious in operation, and lacks a convenient quick disassembly and assembly mechanism, greatly restricting the flexible deployment of equipment.

[0004] Aiming at the new requirements of remotely controlled turrets for the marching fixator, the existing marching fixators for remotely controlled turrets have obvious deficiencies and are difficult to meet the current and future changing needs. There is an urgent need for a marching fixator that can simultaneously achieve unmanned operation and elevation and azimuth fixation at the same time to fill the current technical gap. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide an elevation-azimuth marching fixator for a remotely controlled turret, which can simultaneously achieve unmanned operation and elevation and azimuth fixation at the same time, and has a simple structure.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

The high-low fixing pin is installed at one end of the lead screw shaft; the azimuth fixing pin is installed at the other end of the lead screw shaft; the output shaft end of the driving motor is installed with the driving gear, and the driving gear meshes with the lead screw gear; the lead screw shaft is adaptively connected with the lead screw gear for transmission; the lead screw shaft is fixedly connected with the limit switch pressing plate; a guiding groove is arranged in the base for restricting the limit switch pressing plate to only translate and not rotate; a pair of limit switches are symmetrically installed on the guiding groove below the limit switch pressing plate, and the limit switch pressing plate cooperates with the limit switches to control the translation distance of the lead screw shaft; the limiting ring is used for limiting the lead screw gear.

[0008] Further, the high-low fixing pin can be inserted into the corresponding fixing hole on the remote-controlled gun turret, and the azimuth fixing pin can be inserted into the corresponding fixing groove on the gun turret base.

[0009] Further, a trapezoidal thread is arranged on the lead screw shaft, which cooperates with the lead screw gear to form a screw transmission pair.

[0010] Further, the lead screw shaft is installed in the corresponding through hole of the base, and the limit switch pressing plate is fixedly connected with the lead screw shaft by screws.

[0011] Further, the base is used for the assembly of the marching fixator, and the protective cover is used for the protection of the marching fixator.

[0012] Further, the limiting ring is two or more limiting rings, so that the limiting of the lead screw gear can be realized.

[0029] To make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in more detail below in combination with specific embodiments and the accompanying drawings of the specification, but the present invention is not limited thereto.

[0030] As Figure 1 shown, a high - low and azimuth marching fixator includes a high - low fixing pin 1, a protective cover 2, an azimuth fixing pin 3, a base 4, a drive motor 5, a drive gear 6, a limit ring 7, a lead screw gear 8, a limit switch pressure plate 9, a limit switch 10, and a lead screw shaft 11. Figure 1(a) shows the overall appearance diagram of the elevation and azimuth marching fixture. Figure 1 (b) shows the three-dimensional structure schematic diagram of the elevation and azimuth marching fixture after removing the protective cover 2. Figure 3 is the sectional view of the elevation and azimuth marching fixture. Figure 2 shows the three-dimensional model diagram of the arrangement of the elevation and azimuth marching fixture in the turret.

[0031] Figure 4 (a) and (b) respectively show the schematic diagrams of the structures of the protective cover 2 and the base 4 of the elevation and azimuth marching fixture. The base 4 is the installation foundation of the marching fixture, and the protective cover 2 provides protection for the components installed in the base 4. The drive motor 5 (as Figure 8 shown) is fixedly installed in the base 4. A drive gear 6 is installed on the output shaft of the drive motor 5. The drive gear 6 is driven by the drive motor 5 and meshes with a lead screw gear 8 (as Figure 9 shown). The inside of the lead screw gear 8 has a trapezoidal thread structure and is matched with a lead screw shaft 11 (as Figure 11 shown). The lead screw shaft 11 is installed in a corresponding through hole in the base 4. When the lead screw gear 8 rotates, it will drive the lead screw shaft 11 to move. In order to ensure that the lead screw shaft 11 moves in a translational motion without rotating, a limit switch pressure plate 9 (as Figure 5 shown) is installed on the lead screw shaft 11. The limit switch pressure plate 9 is connected to the lead screw shaft 11 by screws. The limit switch pressure plate 9 is restricted by a guide groove provided in the base 4 and cannot rotate, but can only move translationally. Therefore, the drive motor 5 can indirectly drive the lead screw shaft 11 to move. When the lead screw shaft 11 moves translationally, it drives the limit switch pressure plate 9 to move together. Limit rings 7 are provided between the lead screw gear 8 and the guide groove and between the bottom side convex part and the lead screw gear 8 for limiting the lead screw gear 8. Preferably, the limit rings 7 are two or more limit rings. A pair of limit switches 10 (as Figure 10 shown) are symmetrically installed on the guide groove below the limit switch pressure plate 9. When the limit switch pressure plate 9 translates along the guide groove, the limit switch pressure plate 9 moves synchronously with the lead screw shaft 11. As the lead screw shaft 11 gradually approaches the preset limit position, the limit switch pressure plate 9 also moves until the inclined surface trigger end thereof touches the upper sensing area of the limit switch 10, and the sensing circuit inside the limit switch 10 is immediately triggered to stop the movement of the lead screw shaft 11. At this time, the elevation fixing pins 1 and the azimuth fixing pins 3 installed at both shaft ends of the lead screw shaft 11 may be in a fixed state or a released state, and the state only depends on the control instruction of the upper level. Thus, the unmanned control function of the marching fixture is realized through the motor and the control signal.

[0032] In addition, to achieve the function of simultaneously fixing the height and azimuth of the marching fixator, a solution is adopted where a height fixing pin 1 and an azimuth fixing pin 3 are respectively installed at both ends of the lead screw shaft 11. When the lead screw shaft 11 moves axially, it drives the height fixing pin 1 to insert into the height fixing hole of the gun turret, and the azimuth fixing pin 3 to insert into the corresponding fixing groove on the gun turret base. To ensure that the lead screw shaft 11 only moves axially without rotating, a limit switch pressure plate 9 for guiding is installed on the lead screw shaft 11. The limit switch pressure plate 9 not only provides a limit for the axial movement distance of the lead screw shaft 11 but also ensures that the lead screw shaft does not rotate. In other words, the limit switch pressure plate 9 is not only used to trigger the limit switch 10 but also to prevent the lead screw shaft 11 from rotating, ensuring that it can only move axially. When the lead screw shaft 11 moves axially, it drives the fixing pins 1 and 3 installed at both ends of the shaft to move together, enabling the two fixing pins to simultaneously fix or release the gun turret, thus realizing the function of one action and two-way fixing. This marching fixator can fix the gun turret in both the pitch and yaw directions at a specified angular position, keeping the gun turret in the correct marching state.

[0033] The working process of the height and azimuth marching fixator for a remotely controlled gun turret according to the present invention will be described below in conjunction with this embodiment.

[0034] 1) In the marching state, the height and azimuth marching fixator is in a fixed state, reliably locking the gun turret to the transport platform. When entering the combat state, the marching fixator needs to be released. A control instruction is issued by the operator.

[0035] 2) After receiving the control instruction, the drive motor 5 rotates in the direction required by the control instruction, thereby driving the drive gear 6, and then driving the lead screw gear 8 to rotate. The lead screw gear 8 drives the lead screw shaft 11 to move axially through the internal trapezoidal thread, thereby driving the height fixing pin 1 and the azimuth fixing pin 3 installed at both ends of the lead screw shaft 11 to move axially. After moving a certain distance, it stops moving until the limit switch pressure plate 9 triggers the limit switch 10. According to the design requirements, at this time, the marching fixator has released the gun turret.

[0036] 3) When switching from the combat state to the marching state, after receiving the instruction, the gun turret should be reset, and the height and azimuth should be reset to the angular positions in the fixed state. Then the marching fixator starts to work until the gun turret is reliably fixed.

[0037] It should be noted that the above-described embodiments are only the preferred embodiments of the present invention. For those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several modifications, improvements, and equivalent replacements can be made to the present invention, and these modifications, improvements, and equivalent replacements are also regarded as falling within the protection scope of the claims of the present invention.
