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 a support cylinder of a naval gun automatic machine. Background Art

[0002] The naval gun automatic machine support tube is the main support of the gun barrel group. Figure 1 As shown, the outer tube body of the support tube includes four parts: a tube cover 1, a front tube 2, a middle tube 3 and a rear tube 4; the four parts are welded in sequence; a conical inner surface is provided in the middle tube 3 and cooperates with the conical outer surfaces corresponding to the six gun barrels, and is fixed by a screw sleeve 5 to ensure that the gun barrels are accurately and stably installed.

[0003] like Figure 2 As shown, when the support tube needs to be disassembled during the maintenance or repair of the naval gun, the special disassembly tool of the original equipment manufacturer must be used to disassemble the support tube. The special disassembly tool includes an operating lever 7 and a disassembly head 8. In general, the special disassembly tool can remove the screw sleeve 5, and then disassemble the outer tube; but due to the poor working condition of the outer tube of the automatic machine cooling system, it is soaked in coolant during use, and a large amount of scale and rust are easily generated on the cylinder body; and when the artillery is fired at high speed, it needs to withstand high temperature and high-frequency vibration, which can easily cause the cylinder body to deform and the stop ring 6 to rust and break. For a broken support tube, it cannot be disassembled by a special disassembly tool. For a support tube with internal rust, if the manufacturer's special disassembly tool is used alone for disassembly, it is easy to cause cracks at the welding or rusted parts of the outer tube parts, causing secondary damage to the outer tube.

[0005] In order to achieve the above-mentioned technical objectives, the utility model adopts the following technical solutions: a naval gun automatic machine support tube disassembly auxiliary tooling, characterized in that: it includes a clamp assembly, a positioning plate and multiple sets of connecting rod assemblies; the clamp assembly includes two semicircular clamps, and the two semicircular clamps are connected by bolts and nuts; the semicircular clamps and the positioning plate are correspondingly provided with connecting holes for the ends of the connecting rods to pass through, an axial hole is provided in the center of the positioning plate, and a positioning pin is also provided on the outside of the axial hole, and the clamp assembly and the positioning plate are connected by a connecting rod assembly.

[0006] Furthermore, the connecting rod assembly includes a connecting rod with a threaded end and a fastening nut connected to the end of the connecting rod.

[0008] Furthermore, the positioning pins are cylindrical positioning pins and two of them are provided.

[0009] Furthermore, a lower edge of one side of the semicircular clamp is provided with an arc chamfer.

[0010] The beneficial effect of the utility model is that the support tube of the naval gun automatic machine can be disassembled by using the disassembly auxiliary tooling of the utility model in conjunction with a special disassembly tool, which can avoid secondary damage to the support tube caused by brute force disassembly.

DETAILED DESCRIPTION

[0023] like Figure 3 As shown, the utility model is a naval gun automatic machine support tube disassembly auxiliary tooling, including a clamp assembly 100, a positioning plate 200 and multiple sets of connecting rod assemblies 300. Among them, the clamp assembly 100 includes two semicircular clamps 101, and a first connecting hole 102 is provided on the semicircular clamp; the radius of the two semicircular clamps 101 is adapted to the outer radius of the support tube ball track. The two semicircular clamps are connected on both sides by bolts 103 and nuts 104 respectively. When in use, the two semicircular clamps 101 correspondingly hold the rear tube of the support tube and are fixedly connected by bolts and nuts, and the rear clamp assembly is firmly connected to the rear tube. A second connecting hole 201 and an axial hole 202 are provided on the positioning plate 200, and the axial hole 202 is opened on the center of the positioning plate. Two positioning pins 203 are also provided on the outside of the axial hole, and the clamp assembly and the positioning plate are connected through the connecting rod assembly 300. Specifically, the relative positions and sizes of the shaft hole 202 and the two positioning pins 203 are designed according to the central shaft and two holes on the disassembly head of the special disassembly tool, so that the positioning plate 200 can be mounted on the disassembly head of the special disassembly tool.

[0024] The connecting rod assembly includes a connecting rod 301 with a threaded end and a fastening nut 302 threadedly connected to the end of the connecting rod. Specifically, for easy storage and storage, the connecting rod includes two rod bodies and a connecting pipe, and the two rod bodies are threadedly connected through the connecting pipe.

[0025] Preferably, Figure 4 As shown, a lower edge of one side of the semicircular clamp 101 is provided with an arc chamfer 110; the arc chamfer 110 can fit with the arc surface of the ball track of the support tube, so that the auxiliary tooling is more stable after installation.

[0026] Furthermore, each semicircular clamp 11 has three first connection holes 12, that is, the clamp assembly 1 has a total of six first connection holes 12, and the positioning plate 2 has six corresponding second connection holes 21; thus, a maximum of six sets of connecting rod assemblies 3 can be connected. The corresponding number of connecting rod assemblies 3 can also be set to six sets.

[0027] When in use, the number of connecting rod assemblies 3 can be set according to the actual situation, such as 2 sets, 4 sets, or 6 sets. If the support tube in good condition is difficult to disassemble, only 2 sets of symmetrical connecting rod assemblies 3 are needed. Of course, 4 sets or 6 sets are also possible, but the installation operation time is increased. If the support tube is rusted and broken, because the support tube cannot bear force and can only rely on the force of the auxiliary tooling, 4 or 6 sets of screw connecting rod assemblies 3 are assembled.

[0028] The operation flow of the present invention is described below through a specific disassembly example.

[0029] When disassembling, first fix the two semicircular clamps 101 on the ball track at the rear of the support tube (such as Figure 5 As shown); then install the disassembly head of the special disassembly tool to the front end of the support tube; then align the positioning pin 203 of the positioning plate 200 with the hole of the special disassembly tool and insert it for installation (as shown Figure 6 Finally, four sets of connecting rod assemblies 300 are used to connect the hoop assembly 100 and the positioning plate 200 (as shown in FIG. Figure 7 as shown).

[0030] Put the operating lever into the round hole of the rotating shaft of the special disassembly tool and rotate it counterclockwise (such as Figure 8 As shown), at this time, the upper screw sleeve of the support tube is slowly screwed out and protrudes a certain distance outside the tube cover (as shown in Fig. 9 When the rotation operation is subject to greater force, use a wrench to symmetrically tighten the nuts on the connecting assembly 300 on one side of the positioning plate 200 (as shown in FIG. Fig.10 As shown in the figure), pull the hoop assembly 100 to move the outer tube of the support tube forward, so that the tube cover and the screw sleeve are flush, and then continue to rotate the operating lever. This cycle is repeated until the support tube is about 60 mm away from the breech (as shown in the figure). Fig.11 As shown, at this time, the cone surface of the middle tube and the cone surface of the barrel have been separated, and the disassembly resistance is very small). At this time, the support tube can be directly disassembled by rotating the lever, the auxiliary tooling can be removed, and the support tube can be directly removed with a special disassembly tool.

[0031] 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.
