Description

Technical Field

[0001] The utility model belongs to the technical field of disassembly tooling, and in particular relates to an auxiliary tooling for disassembling and assembling a recoil spring of a naval gun. Background Art

[0002] like Figure 1 As shown, a certain type of single-barreled naval gun recoil spring 2 is arranged on the barrel 1 of the naval gun. Due to being in a semi-exposed state for a long time, the recoil spring is easily corroded by seawater erosion and easily covered with dust and other debris, which affects the normal recoil and recoil action of the naval gun, causing the naval gun to be unable to fire normally. In order to extend the service life of the naval gun and ensure normal operation, the recoil spring needs to be regularly inspected, cleaned and maintained. At present, when disassembling the recoil spring, the barrel 1 needs to be lifted out at the dock or during grade repairs, and then the barrel assembly tool can be used to disassemble it. The whole process is cumbersome and the disassembly time is long. Due to the limitation of the site, the maintenance and maintenance of the naval gun are seriously restricted. Summary of the invention

[0003] The purpose of the utility model is to provide an auxiliary tool for disassembling and assembling a naval gun recoil spring, which can limit the recoil spring when the naval gun recoil spring is disassembled and assembled in a repair shop or on a ship, facilitate the disassembly and installation of the retaining ring, and improve the overall disassembly and assembly efficiency.

[0005] Furthermore, the non-circular connecting hole is a racetrack-shaped hole or a square hole.

[0006] Furthermore, a wrench positioning platform is symmetrically provided in the middle of the sleeve.

[0007] Furthermore, the conical cover and the first connecting ear are fixed by welding. The circular ring and the second connecting ear are integrally formed.

DETAILED DESCRIPTION

[0016] like Figure 2 As shown, the utility model is a naval gun recoil spring disassembly and assembly auxiliary tool, comprising a first clamping component 100, a second clamping component 200 and two sets of connecting components 300, and the first clamping component 100 and the second clamping component 200 are connected by the two sets of connecting components 300.

[0017] The first clamping member 100 includes a conical cover 101 and first connecting ears 102 fixedly connected to two sides of the conical cover. A central through hole 103 is formed on the conical cover 101 ; and two first non-circular connecting holes 104 are formed on the first connecting ears 102 .

[0018] The second clamping member 200 includes a ring 201 and second connecting ears 202 fixedly connected to both sides of the ring, the inner hole of the ring is provided with a thread 203, and the thread 203 is consistent with the thread of the muzzle nut of the gun body. The second connecting ear 202 is provided with two second non-circular connecting holes 204.

[0019] Specifically, the conical cover 101 and the first connecting ears 102 on both sides are welded and fixed to ensure the rigidity of the structure. The ring 201 and the second connecting ears 202 are integrally formed.

[0020] The connection assembly 300 includes two screw rods, two fastening nuts 303 and a sleeve 304 with internal threads. Each screw rod includes a screw rod body 311, a block 312 connected to one end of the screw rod body and a threaded connector 313 connected to the block; the two fastening nuts 303 are respectively connected with the threaded connectors of the two screw rods. Specifically, the two screw rods are respectively recorded as the first screw rod 301 and the second screw rod 302. The shape of the block of the first screw rod 301 is adapted to the first non-circular connection hole 104, and the shape of the block of the second screw rod 302 is adapted to the second non-circular connection hole 204. The screw threads on the screw rod bodies of the first screw rod 301 and the second screw rod 302 are in opposite directions. The first screw rod 301 is a left-handed screw thread, and the second screw rod 302 is a right-handed screw thread. With such a design, when the first screw rod 301 and the second screw rod 302 are connected to the two ends of the sleeve respectively, when the sleeve is rotated, the two screw rod bodies can be screwed in or out of the sleeve at the same time. During assembly, the threaded connector of the first screw rod 301 passes through the first non-circular connecting hole 104 and is connected to a fastening nut 303. After fastening, the clamping block of the first screw rod 301 cooperates with the first non-circular connecting hole 104 to clamp, so that the first screw rod 301 cannot rotate; the threaded connector of the second screw rod 302 passes through the second non-circular connecting hole 204 and is connected to another fastening nut 303. After fastening, the clamping block of the second screw rod 302 cooperates with the second non-circular connecting hole 204 to clamp, so that the second screw rod 302 cannot rotate.

[0021] Preferably, the first non-circular connecting hole 104 and the second non-circular connecting hole 204 are track-shaped holes, which can prevent rotation by the cooperation between the block and the track-shaped hole after the screw rod is connected. Of course, they can also be designed as square holes, which can also achieve position limiting and anti-rotation.

[0022] Preferably, a wrench clamping platform 305 is symmetrically provided in the middle of the sleeve 304. When the sleeve needs to be rotated, the wrench can be clamped on the wrench clamping platform 305 to prevent slipping.

[0023] The process of compressing the recoil spring by using the utility model of the naval gun recoil spring disassembly and assembly auxiliary tooling is as follows: first, remove the muzzle nut and the support sleeve, and pass the central through hole 103 of the first clamp 100 through the barrel of the naval gun and push it to the front support of the barrel; then put the support sleeve back on the barrel, and install the second clamp 200 on the installation position corresponding to the muzzle nut; then connect the first clamp and the second clamp with two sets of connection components 300; then two people use wrenches to rotate the sleeves on both sides at the same time, so that the first screw rod and the second screw rod are screwed out of the sleeve at the same time. Since the first clamp is fixed, the length of the connection component becomes longer after the first screw rod and the second screw rod are screwed out of the sleeve at the same time, so the first clamp will move toward the tail of the barrel to compress the recoil spring until the retaining ring leaks out.

[0024] If the recoil spring is to be disassembled, after the retaining ring leaks out, the retaining ring can be removed according to the normal operation to complete the disassembly of the recoil spring. If the recoil spring is to be installed, when the recoil spring is compressed and the retaining ring leaks out of the position, the retaining ring is installed, and the installation of the recoil spring is completed after completing the corresponding procedures.

[0025] The above contents are only used to illustrate the technical solution of the present utility model. Simple modifications or equivalent substitutions of the technical solution of the present utility model by ordinary technicians in this field do not deviate from the essence and scope of the technical solution of the present utility model.
