[0002] Rifling, also known as rifling grooves, refers to a series of spiral protrusions and grooves on the wall of the gun barrel's guide section, forming a certain angle with the barrel axis. Its function is to impart a certain rotational speed to the projectile upon exiting the muzzle, ensuring the projectile's stability during flight. Existing methods for honing the inner wall of the rifling grooves involve rotating a honing rod with six honing cutters positioned circumferentially upwards. As the honing cutters move outwards, they contact the inner wall of the barrel, and then the movement of the honing rod hones the rifling grooves. However, this method still has the following drawbacks:

[0003] During use, the honing cutter on the honing rod needs to be rotated and moved out, which connects the honing cutter to the drive device, making it difficult to disassemble and install, and inconvenient to maintain the honing cutter. Utility Model Content

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Depend on Figure 1-5 The present invention relates to a honing rod for honing rifling grooves, comprising a honing rod 1, a honing assembly 2 installed at the end of the honing rod 1, and a pushing and rotating component provided inside the honing rod 1;

[0026] The honing assembly 2 includes six mounting slots 201 equally angled on the outer side of the end of the honing rod 1. A mounting plate 202 is provided inside each mounting slot 201. A honing blade 203 is mounted on the mounting plate 202. A snap-fit ​​fastener is installed at one end of the mounting plate 202. The snap-fit ​​fastener includes a movable slot 204 formed inside one end of the mounting plate 202. Rod slots 205 are symmetrically formed at both ends of the movable slot 204. A movable plate 206 is movably mounted inside the movable slot 204. Two movable plates 206 are spaced far apart from each other. A rod 207 is installed on each side. A limit groove 208 is opened at an equal angle on the outer wall of the rod 207. The rod 207 passes through the rod groove 205 to the outer side of the mounting plate 202. A rotating component 12 is provided on the inner walls of both sides of the mounting groove 201. A return spring 209 is fixedly installed between the two movable plates 206. A sliding groove 210 is opened at the top of the movable groove 204. The sliding groove 210 extends to the outer side of the mounting plate 202. A sliding plate 211 is installed on the movable plate 206. The sliding plate 211 is slidably connected to the sliding groove 210.

[0027] The rotating assembly 12 includes symmetrically arranged limiting rotating grooves 1201 on both sides of the mounting groove 201. A limiting rotating block 1202 is rotatably installed inside the limiting rotating groove 1201. The limiting rotating block 1202 rotates under air pressure, causing the honing cutter 203 to contact the inner wall of the pipe. Two insert rods 207 are movably mounted on the mounting plate 202. When the sliding plate 211 is pushed, the two insert rods 207 move closer together and enter the movable groove 204, facilitating the removal of the mounting plate 202. When the sliding plate 211 is released, the insert rods 207 move back and engage in the slot 1204 under the elastic force of the return spring 209, facilitating the installation of the honing cutter 203. The outer side of the limiting rotating block 1202 is provided with toothed grooves 12 at equal angles. 03. The limiting rotating block 1202 has a slot 1204 inside. The inner wall of the slot 1204 is equipped with a limiting block 1205 at equal angles. The insertion rod 207 is inserted into the slot 1204, and the limiting block 1205 is slidably disposed inside the limiting groove 208. The inner wall of the slot 1204 is equipped with a limiting block 1205 at equal angles, and the outer wall of the insertion rod 207 is provided with a limiting groove 208 at equal angles. When the insertion rod 207 is inserted into the slot 1204, the limiting groove 208 moves along the limiting block 1205, so that the insertion rod 207 is engaged and positioned with the limiting rotating block 1202. This allows the rotation of the limiting rotating block 1202 to drive the mounting plate 202 to rotate, which facilitates the honing of the rifling groove.

[0028] The rotating component includes an inner groove 6 inside the honing rod 1. Plate grooves 7 are evenly provided on the side of the inner groove 6 near the mounting groove 201. The plate grooves 7 correspond one-to-one with the limiting rotating grooves 1201 and are connected to the limiting rotating grooves 1201. A piston plate 8 is movably installed inside the inner groove 6. A connecting rod 9 is evenly installed on the side of the piston plate 8 near the mounting groove 201. A toothed plate 10 is installed at one end of the connecting rod 9. The toothed plate 10 is slidably installed inside the plate groove 7 and meshes with the toothed groove 1203. A compression spring 11 is installed on the side of the piston plate 8 near the mounting groove 201. An air chamber 5 is provided at the end of the inner groove 6 away from the mounting groove 201. An air pipe 3 is installed on the outer wall of the end of the honing rod 1 away from the mounting groove 201. A valve 4 is installed on the air pipe 3. One end of the air pipe 3 is connected to the air chamber 5.

[0029] Working principle: During operation, the honing rod 1 is inserted into the pipe where the rifling grooves need to be honed. Then, one end of the air pipe 3 is connected to the air pump, and the valve 4 is opened. Air is pumped into the air chamber 5, increasing the air pressure on one side of the piston plate 8. This pushes the piston plate 8 towards the mounting groove 201, thereby causing the toothed plate 10 to move along the groove 7. The toothed plate 10 meshes with the toothed groove 1203, thereby causing the limiting rotating block 1202 to rotate. The mounting plate 2... The insertion rod 207 on 02 is inserted into the slot 1204 inside the limiting rotating block 1202, and the limiting block 1205 is inserted into the limiting groove 208, so that the limiting rotating block 1202 rotates and drives the mounting plate 202 to rotate outward until the honing cutter 203 contacts the inner wall of the pipe. Then the valve 4 is closed. Under the action of air pressure, the mounting plate 202 cannot rotate back, so that the honing cutter 203 can move with the honing rod 1 to hone the rifling groove inside the pipe.

[0030] When the honing cutter 203 wears out after prolonged use and needs to be replaced, the two movable plates 206 are pulled closer together by the sliding plate 211, so that the two insert rods 207 enter the inner side of the movable groove 204, causing the insert rods 207 to disengage from the slot 1204, thereby making it easy to remove the mounting plate 202 to replace the honing cutter 203 for subsequent use.
