Abstract
Description
Technical Field
[0001] This utility model belongs to the field of machine gun weapon station technology, specifically relating to a cradle structure for a machine gun weapon station. Background Technology
[0002] Weapon mounts typically employ a double trunnion-supported cradle structure to achieve synchronized elevation and depression movements of the sight and weapon. The cradle, as the direct carrier of the weapon, is mounted on a bracket via two trunnions. There are various methods for mounting weapons on the cradle. 30mm caliber artillery usually has its own built-in buffer, eliminating the need for a separate buffer on the cradle; the artillery is directly connected to the cradle via its own rails and retaining pins. However, weapons smaller than 30mm caliber, especially larger caliber machine guns, lack external buffers, resulting in insufficient forward and backward recoil during firing. Furthermore, the trunnions and bracket are subjected to greater impact loads and are prone to damage. Utility Model Content
[0003] The purpose of this invention is to solve the problem that small-caliber weapons with a caliber of less than 30 mm do not have a buffer device, which results in the weapon not being able to recoil during firing and the trunnion and bracket bearing a large impact. The invention provides a cradle structure for machine gun weapon stations. This cradle structure adds a buffer device to the cradle, which realizes the forward and backward recoil of the weapon during firing and reduces the force on the trunnion and bracket.
[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0005] This utility model provides a cradle structure for a machine gun weapon station, including a cradle, a guide rail, a slide, a buffer rod, and a buffer spring;
[0006] The cradle is used to connect to the weapon station and support the guide rail, slide, buffer rod and buffer spring. It adopts a double trunnion hole slot structure. Two trunnion holes are symmetrically arranged on one side wall, and the other end is fixed to the guide rail parallel to the slot. The guide rail has a protrusion protruding vertically upward.
[0007] The slide is mounted to the guide rail so that the protrusion of the guide rail passes through the slide and the slide can slide along the guide rail. The slide is provided with a weapon mounting structure for fixing the weapon on the first end and the second end of the slide in the sliding direction of the guide rail, and the first end is closer to the trunnion hole of the cradle than the second end. The protrusion is located between the first end and the second end.
[0008] The buffer rod is used to connect the slide and the guide rail and to install it parallel to the guide rail. One end of the buffer rod is connected to the protrusion of the guide rail, and the other end is connected to the second end of the slide.
[0009] The buffer spring is used to buffer the forward and backward recoil when the weapon is fired, and it is sleeved on the buffer rod between the protrusion and the second end.
[0010] Furthermore, the slide includes a base plate parallel to the guide rail and two mounting seats extending vertically from the base plate, with protrusions of the guide rail passing through the base plate; the weapon mounting structure includes mounting seats and fixing clamps connected opposite to the mounting seats, with the mounting seats and fixing clamps cooperating to fasten the weapon.
[0011] Furthermore, the mounting base at the first end of the slide is composed of two symmetrical L-shaped components, with one leg of the L-shaped component perpendicular to the substrate and the other leg extending outward parallel to the substrate to receive the first fastener that passes through the substrate perpendicularly, thereby connecting the mounting base to the fixing hoop.
[0012] Furthermore, the mounting base at the second end of the slide is U-shaped, with a through hole at the bottom for the buffer rod to pass through, and two protruding shoulders at the top for the second fastener connecting the mounting base and the fixing hoop to pass through.
[0013] Furthermore, there are two buffer rods and two buffer springs symmetrically arranged.
[0014] Furthermore, the buffer rod is connected to the protrusion via a threaded connection and locked in place by a nut and a cotter pin.
[0015] Furthermore, the cradle is equipped with a toothed arc plate structure at the bottom for connecting to the elevation mechanism of the weapon station to perform the pitching motion of the cradle structure on the weapon station.
[0016] The advantages of this utility model are:
[0017] 1. The cradle structure for a machine gun weapon station of this utility model features a guide rail fixedly connected within a groove of a cradle employing a double trunnion structure. A slide mounting the machine gun or other weapon can slide along the guide rail. A buffer spring is fitted onto a buffer rod parallel to the guide rail. One end of the buffer rod is connected to a protrusion on the guide rail that passes through the slide, and the other end is connected to the slide. Therefore, this utility model has a compact structure. For small-caliber weapons without external buffering devices, such as large-caliber machine guns, it can provide a buffering device, thereby mitigating the forward and backward recoil of the weapon during firing. Simultaneously, the spring buffers the impact load, reducing the stress on the trunnions and the support, thus protecting them.
[0018] 2. The cradle structure provided by this utility model can be used for both weapons without buffer devices and large-caliber weapons with built-in buffer devices. It has strong applicability and can be widely used in general-purpose machine gun weapon stations. Attached Figure Description

[0031] This utility model provides a cradle structure for a machine gun weapon station, which is used to connect to a machine gun weapon station and install weapons such as machine guns. On the one hand, it can be used for large-caliber weapons with built-in buffer devices, and on the other hand, it can be used for small-caliber weapons without external buffer devices, such as large-caliber machine guns. It can provide a buffer device for small-caliber weapons to realize the forward and backward recoil of the weapon during firing.
[0032] Overall reference Figure 1 As an exemplary embodiment of this utility model, the cradle structure for a machine gun weapon station may include a cradle 1, a guide rail 2, a slide 3, a buffer rod 4, and a buffer spring 5. The cradle 1 is the supporting mechanism for the entire structure, used to connect to the weapon station and support the guide rail 2, the slide 3, the buffer rod 4, and the buffer spring 5. The guide rail 2 is used to connect the cradle 1 and the slide 3 on one hand, and to realize the sliding of the slide 3 relative to the cradle 1 on the other hand. It is an important structure for realizing the forward and backward movement of the weapon. The slide 3 is used to install and fix the weapon and is the carrier of the weapon. The buffer rod 4 is used to connect the guide rail 2 and the slide 3 and to install the buffer spring 5. The buffer spring 5 is used to absorb and buffer the impact load during weapon firing.
[0033] Combination Figure 2 The cradle 1 is roughly rectangular and adopts a double trunnion slot structure. Two trunnion holes 11 are symmetrically arranged on one side wall for connecting the cradle structure to the weapon station. The pitching motion of the structure on the weapon station is achieved through double trunnion support. A guide rail 2 is fixedly connected parallel to the slot at the other end. The cradle 1 may have a toothed arc plate structure 12 at its bottom for connecting to the elevation mechanism of the weapon station to perform pitching motion, facilitating precise pitch angle control. The cradle 1 can be manufactured using a welding-then-machining process or directly cast.
[0034] like Figure 3 As shown, the guide rail 2 has a protrusion 21 protruding vertically upwards, which is used to connect the guide rail 2 and the slide 3. The bottom of the guide rail 2 may have a downwardly extending square protrusion, which can be inserted into the rectangular opening at the bottom of the groove of the rocker arm 1 to connect the rocker arm 1 and the guide rail 2. The guide rail 2 may have protruding tabs 22 on both sides at both ends as slide rails to provide the sliding part of the slide 3 on the guide rail. The guide rail 2 is required to have good strength, high precision, and reliable operation.
[0035] Combination Figure 4The slide block 3 is mounted to the guide rail 2, allowing the protrusion 21 of the guide rail 2 to pass through the slide block 3. The slide block 3 can slide relative to the cradle 1 along the guide rail 2, realizing the forward and backward recoil action when the weapon is fired. In particular, the bottom of the slide block 3 may be provided with a through groove, and the sides of the groove bottom are machined with sliding grooves 39 as sliding tracks. The protrusion 22 of the guide rail 2 cooperates with the sliding grooves 39 and slides along them. The slide block 3 has weapon mounting structures for fixing the weapon on the first end 31 and the second end 32 along the sliding direction of the guide rail 2, and the first end 31 is closer to the trunnion hole of the cradle 1 than the second end 32. The protrusion 21 is located between the first end 31 and the second end 32. After the weapon is installed in place, the weapon is located above the buffer rod and the buffer spring (described below).
[0036] In some embodiments of this utility model, the slide block 3 includes a base plate parallel to the guide rail 2 and two mounting seats extending vertically upward from the base plate. A sliding groove 39 is located on the base plate, and the protrusion 21 of the guide rail 2 passes through a through hole in the middle of the base plate. The mounting seats are a first mounting seat 33 at the first end 31 and a second mounting seat 34 at the second end 32. The weapon mounting structure includes two mounting seats and fixing clamps opposite to the mounting seats, namely a first fixing clamp 35 and a second fixing clamp 36, as shown in the figures below. Figure 5 and Figure 6 As shown, the mounting base and the fixing clamps cooperate to secure the weapon. It should be understood that the surfaces of the two fixing clamps that mate with the weapon can be designed according to the weapon's adaptability to firmly clamp the weapon. Specifically, one weapon mounting structure includes a first mounting base 33 and a first fixing clamp 35, and another weapon mounting structure includes a second mounting base 34 and a second fixing clamp 36.
[0037] Optionally, the mounting base at the first end 31 of the slide 3, i.e., the first mounting base 33, consists of two symmetrical L-shaped components, with one leg of the L-shaped component perpendicular to the substrate and the other leg extending outward parallel to the substrate to receive a first fastener 37, such as a screw or pin, that passes perpendicularly through the substrate. Figure 1 (As shown in the image), thereby connecting the mounting base to the fixing clamp.
[0038] Furthermore, the mounting seat at the second end 32 of the slide 3, i.e., the second mounting seat 34, may be U-shaped, with a through hole at the bottom for the buffer rod 4, which will be described in detail below, to pass through, and two protruding shoulders at the top for the passage of a second fastener 38, such as a screw or pin, connecting the mounting seat and the fixing clamp. Figure 1 (as shown in the image).
[0039] Combination Figure 7The buffer rod 4 serves as another connecting component between the rocker arm 1 and the slide 3, connecting the slide 3 and the guide rail 2 and installing it parallel to the guide rail 2. One end of the buffer rod 4 is connected to the protrusion 21 of the guide rail 2, and the other end is connected to the second end 32 of the slide 3. Preferably, the buffer rod 4 includes a head 41 and a rod portion 42. The head 41 is connected to the second mounting seat 34 at the second end 32 of the slide 3, and the end of the rod portion 42 passes through the protrusion 21 of the guide rail 2 and is connected to the protrusion 21 by a threaded connection, and then locked by a nut 6 and a cotter pin 7.
[0040] The buffer spring 5 is used to buffer the forward and backward recoil force during weapon firing, and is sleeved on the rod portion 42 of the buffer rod 4 between the protrusion 21 and the second end 32. The buffer rod 4 serves to guide the buffer spring 5 during compression and extension. The diameter and material strength of the spring must meet the requirements of the recoil force. In some embodiments, two buffer rods 4 and two buffer springs 5 are symmetrically arranged to better buffer the forward and backward recoil force. With the above structure, when the weapon is fired and recoils, the weapon drives the slide 2 to slide backward on the guide rail 3 (from the second end 32 of the slide to the first end 31). The buffer spring 5 is compressed and absorbs the recoil force. After the recoil is completed, the buffer spring 5 extends under the action of the restoring force, releasing the spring force. The slide 2 returns to the initial position before the weapon was fired under the action of the spring force. The contraction and extension of the two buffer springs 5 are achieved by the relative movement on the two buffer rods 4.
[0041] The installation process of the cradle structure for the machine gun weapon station of this utility model is described below:
[0042] Step S1: Pass the guide rail 2 through the middle of the slide block 3 from top to bottom. By moving the guide rail 2 back and forth, the front and rear rails of the slide block 3 and the front and rear slide rails of the guide rail 2 are assembled, and the rails and slide rails slide smoothly against each other. Then, fix the protrusion 21 of the guide rail 2 into the slot in the middle of the rocker arm 1 to realize the connection between the rocker arm 1, the guide rail 2 and the slide block 3.
[0043] Step S2: The first fixing hoop 35 and the second fixing hoop 36 are respectively fixed to the first mounting base 33 and the second mounting base 34 of the slide block 3 by the first fastener 37 and the second fastener 38.
[0044] Step S3: Insert the spring rod 4 from the outside of the slide block 3 into the first mounting base 33, then put the buffer spring 5 on the spring rod 4, then pass the spring rod 4 out through the two holes on the protrusion 21 of the guide rail 2, and finally lock it with the nut 6 and the cotter pin 7.
[0045] Step S4: Install the cradle 1 to the weapon station trunnion through the two trunnion holes on the cradle 1, and connect the toothed arc plate structure 12 of the cradle 1 to the elevation mechanism of the weapon station.
[0046] As described above, this invention features a compact structure. For small-caliber weapons without external buffers, such as large-caliber machine guns, it can provide a buffer, thereby mitigating the forward and backward recoil during firing. Simultaneously, the springs cushion the impact load, reducing the stress on the trunnion and bracket, thus protecting them. Furthermore, the cradle structure provided by this invention is suitable for both weapons without buffers and large-caliber weapons with built-in buffers, demonstrating strong applicability and wide applicability to general-purpose machine gun weapon stations.
[0047] Finally, it should be noted that the features mentioned and / or shown in the above description of exemplary embodiments of the present invention can be combined in the same or similar manner with one or more other embodiments, combined with features in other embodiments, or substituted for corresponding features in other embodiments. These combined or substituted technical solutions should also be considered as included within the protection scope of the present invention.
