[0002] A hole punching machine is a kind of hole opening equipment often used in production construction, mainly used for pipe hole opening. When in use, the hole punching machine needs to drill a target through a barrel cutter assembled on the equipment. If the connection between the barrel cutter and the equipment is not firm, the quality of hole opening will be reduced. Most of the existing barrel cutter connection parts on the hole punching machine are not provided with a self-locking structure. In the actual use process, the barrel cutter will loosen due to the vibration of the machine, and more seriously, the barrel cutter will fall off, affecting the hole opening quality. In addition, the existing hole punching machine needs to use tools to assist when replacing the barrel cutter, and the operation is relatively cumbersome, affecting the hole opening efficiency.
[0003] Based on this, a barrel cutter connection structure for a hole punching machine with a self-locking structure is provided now, which can eliminate the disadvantages of the existing device. Content of the Utility Model

Detailed implementation mode
[0022] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.
[0023] In one embodiment, as Figures 1 - 3 shown, a cutter barrel connecting structure for a hole-punching machine with a self-locking structure includes a connecting seat 100. A connecting component 200 is provided at the bottom of the connecting seat 100, and a cutter barrel connecting component 300 is provided at the connection between the connecting seat 100 and the connecting component 200. A self-locking mechanism is provided in the connecting component 200, and a disassembly mechanism is provided at the bottom of the cutter barrel connecting component 300. The self-locking mechanism is used to reinforce and lock the cutter barrel connecting component 300 during the operation of the hole-punching machine, preventing the cutter barrel connecting component 300 from shaking due to machine vibration and affecting the hole-opening quality of the limiting groove 307. The cutter barrel 311 can be quickly disassembled and replaced through the disassembly mechanism, improving the hole-opening efficiency.
[0024] In one embodiment, as Figure 2As shown, the connection component 200 includes a first groove 201, a connecting rod 202, and a self-locking mechanism. The bottom of the connection seat 100 is provided with a first groove 201, the first groove 201 is provided with a connecting rod 202, and the connecting rod 202 is provided with a self-locking mechanism. The self-locking mechanism includes a first chute 203, a second chute 204, a second groove 205, a return spring 206, and a slider 207. The inner wall of the first groove 201 is provided with a first chute 203. The surface of the connecting rod 202 is provided with a second chute 204 corresponding to the position of the first chute 203. Two symmetric sliders 207 are provided in the second chute 204. Two symmetric second grooves 205 are provided at the bottom of the second chute 204. A return spring 206 is provided in the second groove 205. One end of the return spring 206 is fixedly connected to the bottom of the second groove 205, and the other end of the return spring 206 is fixedly connected to the slider 207. During operation, when the connection seat 100 drives the cylinder knife connection component 300 to rotate, under the action of centrifugal force, the slider 207 moves outward into the first chute 203. The faster the machine rotates, the more the slider 207 enters the first chute 203. Under the action of the slider 207, the cylinder knife connection component 300 is prevented from falling off the connection seat 100. When the machine stops running, the slider 207 is reset under the action of the return spring 206, and it will not interfere with the removal of the cylinder knife connection component 300.
[0025] In one embodiment, as Figure 3 shown, the cylinder knife connection component 300 includes a knife seat 301, a limit ring 302, a third groove 308, and a disassembly mechanism. A rotating ring 303 is provided around the outside of the knife seat 301. A third groove 308 is provided at the bottom of the knife seat 301. A disassembly mechanism is provided in the third groove 308. The disassembly mechanism includes a rotating ring 303, bevel gears 304, perforations 305, bevel gear screws 306, limit grooves 307, fastening blocks 309, screw holes 310, and a cylinder knife 311. The rotating ring 303 is provided below the limit ring 302. The rotating ring 303 is slidably connected to the knife seat 301. The lower end of the rotating ring 303 is provided with bevel gears 304. Three perforations 305 are evenly distributed on the surface of the knife seat 301 below the rotating ring 303. The perforations 305 penetrate through the knife seat 301. The bevel gear screws 306 are slidably connected to the perforations 305 through the limit grooves 307. Three fastening blocks 309 are provided in the third groove 308. Screw holes 310 are provided on the surface of the fastening blocks 309 corresponding to the positions of the perforations 305. A cylinder knife 311 is provided on the inner side of the fastening block 309 facing inward. The bevel gear screws 306 pass through the perforations 305 and are threadedly connected to the third groove 308 through the screw holes 310. When the cylinder knife 311 needs to be disassembled, hold the bevel gears 304 with the hand and rotate to drive the bevel gear screws 306 to rotate, so that the fastening blocks 309 move in the direction of the bevel gear screws 306, thereby loosening the fastening blocks 309. Finally, take out the cylinder knife 311 from the middle of the fastening blocks 309.
[0026] The above embodiments disclose a connecting structure for a barrel cutter used in a hole punching machine with a self-locking structure. During operation, the connecting seat 100 drives the connecting rod 202 to rotate. Under the action of centrifugal force, the slider 207 moves outward and enters the return spring 206. The faster the rotation speed, the more the slider 207 enters the first chute 203, thereby strengthening the connection between the connecting seat 100 and the barrel cutter connecting assembly 300 to achieve the self-locking effect. By rotating the bevel gear 304, the fastening block 309 is loosened or tightened, facilitating the disassembly, replacement, and installation of the barrel cutter 311 quickly and improving the hole opening efficiency.
[0027] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
