[0022] It should be noted that the embodiments and features of the embodiments in the present application can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0023] Referring to Figs. 1 to 3 The utility model provides a kind of quick repair numerical control cutter, it include: tool holder 1, blade 2, anti-drop piece 3, stop piece 4.

[0024] In the embodiment, tool holder 1 is cuboid. Tool holder 1 is used to install the fixture of numerical control machine tool. Through hole 10 is formed in tool holder 1. The cross section of the through hole is rectangular. The through hole 10 has an input end and an output end.

[0025] Blade 2 is slidably arranged in the through hole 10. The blade can slide along the length direction of the through hole. Blade 2 has opposite blade head and blade tail. The cutting edge 21 in the middle of the blade head extends to the outside of the output end of the through hole. The outer side wall of the blade 2 is formed with a plurality of pre-breaking grooves 20. The plurality of pre-breaking grooves 20 are arranged along the length direction of the blade 2. The pre-breaking grooves 20 are arranged along the circumferential direction of the blade 2.

[0026] The inner wall of the output end of the through hole is provided with a first assembly hole. The anti-drop piece 3 is telescopically installed in the first assembly hole by the air cylinder 31. One end of the anti-drop piece 3 extends into the through hole 10, and the one end of the anti-drop piece 3 abuts against the blade head to prevent the blade 2 from sliding out of the output end of the through hole 10.

[0027] As a preferred embodiment, the air cylinder 31 has opposite telescopic end and fixed end. The tool holder 1 is provided with a through hole communicating with the first assembly hole. The fixed end of the air cylinder 31 is fixedly arranged outside the tool holder 1. The telescopic end of the air cylinder 31 is movably arranged in the through hole, and the telescopic end of the air cylinder 31 is connected to the anti-drop piece 3.

[0028] A plurality of second assembly holes are formed in the inner side of the hole wall of the accommodating channel 10. The second assembly holes are arranged at intervals along the length direction of the accommodating channel 10. The interval between two adjacent second assembly holes is adapted to the interval between two adjacent pre-breaking grooves 20. A retreat-preventing piece 4 is elastically mounted in each second assembly hole. One end of the retreat-preventing piece 4 in the assembly hole at the tail of the blade extends into the accommodating channel 10 and presses against the tail of the blade to prevent the blade from retreating.

[0029] In this embodiment, second assembly holes are formed in the hole walls of the opposite sides of the accommodating channel 10.

[0030] In this embodiment, a pushing spring 41 is connected between the other end of the retreat-preventing piece 4 and the hole bottom of the second assembly hole. The retreat-preventing piece is wedge-shaped, and the inclined side of the retreat-preventing piece is arranged to face the input end of the accommodating channel. When the blade is pushed towards the output end through the input end of the accommodating channel, the retreat-preventing piece can be pressed into the second assembly hole and retreat back into the second assembly hole. When the blade passes a second assembly hole, one end of the retreat-preventing piece in the second assembly hole extends into the accommodating channel and abuts against the tail end of the blade.

[0031] As a preferred embodiment, a third assembly hole is formed in the inner wall of the output end of the accommodating channel 10. An electric conveying roller 5 is mounted in the third assembly hole. The wheel surface of the electric conveying roller presses against the blade 2. In this embodiment, the wheel shaft of the electric conveying roller is arranged along the thickness direction of the blade.

[0032] As a preferred embodiment, a third assembly hole is formed in the inner wall of the output end of the accommodating channel 10. An electric conveying roller 5 is mounted in the third assembly hole. The wheel surface of the electric conveying roller presses against the blade 2. In this embodiment, the wheel shaft of the electric conveying roller is arranged along the thickness direction of the blade.

[0033] In use, the blade is inserted into the accommodating channel of the blade sheath through the input end of the accommodating channel, and is pushed towards the output end of the accommodating channel, so that the cutting edge of the blade head extends to the outside of the output end of the accommodating channel. At this time, one end of the retreat-preventing piece extends into the accommodating channel and presses against the end surface of the blade head, and one retreat-preventing piece at the tail of the blade presses against the end surface of the tail of the blade, so that the blade is stably clamped between the retreat-preventing piece and the retreat-preventing piece.

[0034] After the cutting edge at the blade head of the blade is worn or damaged, the retreat-preventing piece is retreated into the first assembly hole under the drive of the air cylinder, and the electric conveying roller is started to make the damaged section of the blade head extend to the outside of the output end of the accommodating channel. At this time, the damaged section of the blade head is broken, and the cutting edge of the remaining blade head can be used after simple grinding. After the cutting edge is ground, the retreat-preventing piece extends into the accommodating channel under the drive of the air cylinder and abuts against the blade head again. When the electric conveying roller conveys the blade head towards the outside of the output end of the accommodating channel, one end of the retreat-preventing piece in a second assembly hole at the tail of the blade extends into the accommodating channel and abuts against the tail of the blade. Therefore, when the retreat-preventing piece abuts against the blade head of the blade again, the blade is clamped and fixed by the retreat-preventing piece and the retreat-preventing piece again, so as to be quickly put into production.

[0035] The utility model discloses a quick repair numerical control cutter, through the insert of the knife cover is provided, and the insert is positioned through the anti -drop piece and the stop piece and avoids its sliding when working, and when the cutting edge of the cutting head of the insert needs to be replaced, through the anti -drop piece and return first assembly hole, and the cutting edge damage one section cutting head is stretched to the outside of the output end of the containing hole of the knife cover, again cutting edge damage one section cutting head is broken, make the cutting edge of the following section cutting head expose the outside of the output end of the containing hole, the cutting edge of the newly exposed cutting head is polished after simple, and the anti -drop piece again confines the insert in the containing hole to quickly put into use.

[0036] The above description is merely preferred embodiments of the present application and a description of the technical principles of the application. It should be understood by those skilled in the art that the utility model range involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or equivalent features without departing from the utility model concept.
