Description

Technical Field

[0001] The utility model belongs to the technical field of cutting milling cutters, and in particular relates to a cutting milling cutter with a dust collecting function. Background Art

[0002] Milling cutters are cutting tools commonly used in milling machines or machining centers to perform milling operations, where they remove material at a fixed feed rate within the machine.

[0003] At present, most cutting milling cutters on the market do not have dust collection function. When the cutting milling cutter rotates at high speed, metal debris will splash, which is not convenient for centralized processing of the metal debris later.

[0004] Based on the above technical problems, it was retrieved that in the prior art, a Chinese utility model patent with authorization announcement number CN218891228U disclosed "a four-blade cutting milling cutter with a dust cover", including a milling cutter body, a mounting plate, an indicator plate, a telescopic tube, a cylinder, a fixed shell, a fixed hole, a counterweight block and a reinforcement rod.

[0005] Although the cutting milling cutters in the prior art including those mentioned above can shield the metal debris, they can only confine the metal debris to the inner side of the cylinder. When the processing is completed and the cutting milling cutter is away from the workpiece, the metal debris will fall, which is also not conducive to the collection of the metal debris.

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] See also Figure 1-Figure 5 The utility model provides the following technical solution: a cutting milling cutter with a dust collection function, comprising a milling cutter body 1 and a bellows 2, and also comprising: a fixing ring 4, a magnetic ring 5 and a rotating tube 3.

[0036] Further, by Figure 1 and Figure 2As shown, in this embodiment, the fixing ring 4 is detachably mounted on the milling cutter body 1, the bellows 2 is detachably mounted on the bottom surface of the fixing ring 4, the magnetic ring 5 is mounted on the bottom surface of the fixing ring 4 and is located on the inner side of the bellows 2, and the rotating tube 3 is rotatably connected to the bottom end of the bellows 2. After adopting the above scheme, when in use, as the milling cutter body 1 is fed, the bellows 2 will gradually shrink, and the rotation of the milling cutter body 1 will drive the bellows 2 to rotate. The bellows 2 can effectively avoid metal debris from splashing, and the magnetic ring 5 can absorb metal debris, which is convenient for collecting and processing metal debris. The rotating tube 3 can rotate freely relative to the bellows 2 to avoid friction between the bellows 2 and the workpiece during processing to cause greater wear, thereby improving the safety of processing.

[0037] It should be noted that, since the workpieces cut by the milling cutter body 1 are mostly steel or other steel-containing alloys, the generated debris can be absorbed by the magnetic ring 5, so the magnetic ring 5 provided in the utility model can effectively absorb the metal debris generated during cutting.

[0038] It should be further explained that, in actual use, the fixing ring 4 can be made of a metal material that can be adsorbed by the magnetic ring 5 to facilitate the installation, removal and cleaning of the magnetic ring 5. The magnetic ring 5 can also be installed in other conventional ways.

[0039] Optionally, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, it also includes: a fixing block 41 and a locking screw 8. The fixing block 41 is fixed to the top surface of the fixing ring 4. The locking screw 8 is installed on the fixing block 41 by threaded engagement. After adopting the above scheme, the utility model uses the locking screw 8 to install and fix the fixing ring 4. After tightening the locking screw 8, the fixing ring 4 can be stably installed. It is also convenient to install and adjust the installation position of the fixing ring 4 as needed.

[0040] Optionally, by Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, it also includes: an elastic sheet 9 and a clamping block 91. A plurality of elastic sheets 9 are fixed at equal intervals along the circumferential direction on the top end of the outer side surface of the corrugated tube 2. A clamping groove 42 is provided on the fixing ring 4 for the elastic sheet 9 to pass through. The clamping block 91 is fixed to the top end of the elastic sheet 9 and forms a clamping structure with the fixing ring 4. After adopting the above scheme, the elastic sheet 9 passes through the clamping groove 42 to position and limit the fixing ring 4. At this time, the clamping block 91 forms a clamping structure with the fixing ring 4, so that the installation of the corrugated tube 2 is realized, and the disassembly is convenient.

The set ball 6 can effectively reduce the sliding friction between the rotating tube 3 and the bellows 2, and ensure the stability of the connection between the rotating tube 3 and the bellows 2. The rotating tube 3 is used to support the workpiece, and the rotating tube 3 and the bellows 2 can generate relative rotation, so as to avoid friction between the bellows 2 and the workpiece during processing to cause greater wear, thereby improving the safety of processing.

[0044] Preferably, by Figure 1 , Figure 2 and Figure 3 As shown, in this embodiment, it also includes: a rubber ring 7, which is bonded and fixed to the bottom end of the rotating tube 3, and the workpiece is supported by the rubber ring 7. The rubber ring 7 is flexible, which avoids friction between the corrugated tube 2 and the workpiece during processing and causes greater wear, thereby further improving the safety of processing.

[0045] Preferably, by Figure 1 As shown, in this embodiment, the inner diameter of the fixing ring 4 is equal to the diameter of the milling cutter body 1, which improves the installation stability of the fixing ring 4 and avoids the fixing ring 4 from shaking relative to the milling cutter body 1 during processing.

[0046] Components not described in detail herein are prior art.

[0047] Working principle and use process of the utility model: when the milling cutter body 1 of the utility model is in use, as the milling cutter body 1 is fed, the bellows 2 will gradually shrink, and the rotation of the milling cutter body 1 will drive the bellows 2 to rotate, and the workpiece is pressed against by the rubber ring 7, and the rotating tube 3 and the bellows 2 can generate relative rotation, so as to avoid the friction between the bellows 2 and the workpiece during processing and cause greater wear, thereby improving the safety of processing;
