Description

Technical Field

[0001] The utility model relates to the technical field of slot cutters, in particular to an outer diameter forming rough slot cutter. Background Art

[0002] In mechanical processing, end face groove forming is often encountered, which usually needs to be processed by a machine. During processing, the workpiece is cut by a cutter head. During the cutting process, the workpiece is rotated to process the outer diameter of the workpiece. Most of the existing cutter heads can only process a certain type of workpiece. If different types of workpieces need to be processed, the cutter head usually needs to be replaced, and the entire cutter head needs to be disassembled for replacement, which affects the processing efficiency. During processing, the cutter head will generate a lot of heat, and cutting fluid is usually sprayed for cooling and lubrication. Spraying cutting fluid can cool the surface of the cutter head, but the heat inside the cutter head cannot be dissipated quickly, which is easy to affect the service life of the cutter head.

[0022] 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.

[0023] See also Figures 1 to 6The utility model provides a technical solution: an outer diameter forming rough groove cutter, including a groove cutter body for processing a workpiece 7, the groove cutter body including a connecting rod 1 and a connecting block 3, the connecting rod 1 corresponds to the connecting block 3, a plurality of cutter heads 2 are installed on the circumference of the connecting block 3, nuts 4 are installed at both ends of the connecting rod 1, a blind hole 6 and a through groove 5 are opened in the middle of the connecting rod 1, the cutter head 2 includes a cutter tip 10 and a plurality of cutting edges 11, a plurality of chip grooves 9 are opened in the connecting block 3, and the chip grooves 9 correspond to the cutter head 2.

[0024] In this embodiment, the connecting rod 1, the connecting block 3 and the cutter head 2 are all made of cemented carbide material. The cutter head 2 includes a reference edge 8, and the cutting tip 10 is 80.1 mm lower than the reference edge. The cutter head 2 is fixedly connected to the connecting block 3. A plurality of concave corners 12 are provided in the cutting edge 11, and the angle of the concave corners 12 is 1° to 2°. The thickness of the connecting block 3 is 5.5 mm.

[0025] Specifically, when processing the workpiece 7, the positions of the connecting rod 1, the connecting block 3 and the cutter head 2 are fixed, and then the workpiece 7 is rotated, and the cutter head 2 is brought close to the workpiece 7 to cut the workpiece 7, thereby achieving rough processing of the workpiece 7. Different types of workpieces 7 can be cut by different cutter heads 2. The cutter head 2 can be replaced by simply rotating the connecting block 3, thereby improving the efficiency of replacing the cutter head 2 and expanding the scope of application of the device.

[0026] The connecting block 3 is threadedly matched with the connecting rod 1. The peripheral side of the connecting rod 1 is provided with threads 13. The threads 13 correspond to the nut 4. The threads 13 at both ends of the connecting rod 1 are in opposite directions.

[0027] Specifically, when the connecting block 3 and the cutter head 2 need to be replaced, the nut 4 can be removed by rotating the nut 4. At this time, the nut 4 will not limit the connecting block 3, and the connecting block 3 can be rotated to be removed. Then, the new connecting block 3 can be threadedly installed with the connecting rod 1, and the connecting block 3 can be clamped and fixed by the nut 4 to realize the installation of the connecting block 3, thereby realizing the replacement of the cutter head 2.

[0028] The blind hole 6 is communicated with the through groove 5, and cutting fluid is installed in the through groove 5.

[0029] Specifically, during the cutting process, the cutting fluid is introduced through the through groove 5 and the blind hole 6, which can have a good cooling effect on the cutter head 2. At the same time, the cutting fluid can also take away the debris after flowing out of the blind hole 6, thereby ensuring the cutting effect.

[0030] 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.
