[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] See also Figures 1 to 5The utility model provides a technical solution: an outer arc groove cutter comprises a blade body 1, a blade head 2 is fixed on both sides of the blade body 1, the blade head 2 comprises a blade 14, a chip groove 3 is provided in the blade head 2, a through groove 4 is provided in the blade body 1, a liquid spray port 5 is provided in the chip groove 3, and the liquid spray port 5 corresponds to the through groove 4, a rotating groove 11 is provided in the blade body 1, a mounting block 6 is installed in the rotating groove 11, a plurality of clamping blocks 9 are installed in the mounting block 6, and the clamping blocks 9 correspond to the blade body 1.

[0023] In this embodiment, the blade body 1 includes a side edge 12, the blade head 2 includes a bevel 13, the angle between the bevel 13 and the side edge 12 is 40°, the blade 14 is an angled structure, the chip groove 3 is located on the inclined side of the blade 14, the chip groove 3 is an arc structure, the liquid spray port 5 is connected to the through groove 4, and the liquid spray port 5 and the blade 14 are arranged opposite to each other.

[0024] Specifically, when cutting, the lubricating liquid is introduced into the through groove 4, and the lubricating liquid can be sprayed out from the liquid spray port 5. The lubricating liquid is sprayed to the connection between the blade 14 and the workpiece, which can have a certain lubrication and cooling effect. At the same time, the lubricating liquid can wash away the debris, prevent the debris from sticking to the blade 14, and prevent the blade 14 from breaking.

[0025] The rotating groove 11 is rotatably connected to the mounting block 6. Mounting grooves 15 are provided in the mounting block 6 and the blade body 1. The two mounting grooves 15 are connected. A plurality of card slots 8 are provided in the rotating groove 11. The card slots 8 correspond to the card block 9. A groove 7 is provided in the mounting block 6. The groove 7 corresponds to the card block 9. A plurality of springs 10 are fixed between the groove 7 and the card block 9. The card block 9 is a C-shaped structure, and the groove 7 is a C-shaped groove.

[0026] Specifically, when the cutter head 2 needs to be replaced, the block 9 is pressed so that the block 9 enters the groove 7 and the spring 10 is compressed. At this time, the block 9 and the slot 8 lose their clamping relationship, which can drive the blade body 1 to rotate, thereby driving the cutter head 2 to rotate, thereby changing the cutter head 2 without disassembling the entire device, thereby improving the efficiency of changing the cutter head 2.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
