[0001] The utility model relates to the technical field of milling processing equipment, and more specifically, to a milling cutter which is easy to maintain. Background Art

[0002] A milling cutter is a rotating tool with one or more teeth, usually used in milling. When working, the workpiece can be milled by the cutting edge on the milling cutter.

[0003] Publication No. CN216706081U discloses a milling cutter, whose technical solution includes a shank and a cutter head. The milling cutter has a central axis, and the cutter head includes a first cutting edge and a plurality of second cutting edges, which are connected in sequence around the central axis. The first cutting edge is provided with a first peripheral cutting edge and a cutting edge band provided along the outer edge of the first peripheral cutting edge, and the plurality of second cutting edges are provided with second peripheral cutting edges. A peripheral cutting edge chip groove is formed between adjacent ones of the first peripheral cutting edge and the plurality of second peripheral cutting edges. On any cross section of the cutter head perpendicular to the central axis, the distance from a point on the cross section of the first peripheral cutting edge to the central axis is greater than the distance from a point on the cross section at a corresponding position of any second peripheral cutting edge to the central axis.

[0004] The above technical solution can perform milling on the surface of the workpiece through the first blade, and at the same time, the cooperation between the first peripheral blade and the blade band can improve the structural strength of the first blade, thereby increasing the service life of the milling cutter and reducing production costs. However, during the milling process of the above technical solution, the first blade will be affected by the hardness and friction of the workpiece, causing damage to the first blade.

[0013] The utility model is further configured as follows: a connecting block is fixedly connected to the inner side wall of the movable ring, and a sliding groove for the connecting block to slide is provided on the connecting rod.

[0014] By adopting the above technical solution, it is possible to prevent the moving ring from rotating on the connecting rod, thereby improving the stability of the moving ring on the connecting rod.

[0015] To sum up, the utility model has the following beneficial effects: when the milling cutter is damaged, the driving component is used to drive the several moving rings to cancel the abutment, and then the restriction on the several moving rings is cancelled by the fixing component, and then the several moving rings are driven to separate from the connecting rod, and then the moving ring connected to the damaged blade is taken out and replaced.

[0025] A milling cutter that is easy to maintain, such as Figure 1-Figure 5 As shown, the milling cutter body includes a rotating rod 1, a connecting rod 2 and a plurality of blades 3. The rotating rod 1 and the connecting rod 2 are fixedly connected. The connecting rod 2 is slidably connected with a plurality of moving rings 4. The plurality of blades 3 and the plurality of moving rings 4 are fixedly connected. The connecting rod 2 is provided with a driving assembly for driving the plurality of moving rings 4 to always keep in contact with each other and a fixing assembly for fixing the plurality of moving rings 4 and the connecting rod 2 with each other. When the milling cutter is damaged, the restriction on the plurality of moving rings 4 is cancelled by the driving assembly, the plurality of moving rings 4 are driven to cancel the contact with each other, and then the restriction on the plurality of moving rings 4 is cancelled by the fixing assembly. Then, several movable rings 4 are driven to start moving along the side wall of the connecting rod 2 and separate from the connecting rod 2, and then the movable ring 4 connected to the damaged blade 3 is taken out and replaced. After the replacement is completed, several movable rings 4 are placed on the connecting rod 2 again, and several movable rings 4 and the connecting rod 2 are fixed to each other again through the fixing assembly, and at the same time, several movable rings 4 are driven to abut against each other through the driving assembly, so as to complete the effect of replacing the damaged blade 3. Through the setting of the fixing assembly, when the milling cutter is damaged, the damaged blade 3 on the milling cutter can be replaced separately, which reduces economic losses and reduces manufacturing costs.

[0026] like Figure 1-Figure 5As shown, the fixing assembly includes a limit plate 5 and a fixing block 6 fixedly connected to the end of the connecting rod 2 away from the rotating rod 1. The fixing block 6 is fixedly connected to a connecting plate 7 on the side away from the connecting rod 2. A through slot 8 for the connecting plate 7 to slide and a clamping slot 9 mutually clamped with the connecting plate 7 are provided on the limit plate 5. The limit plate 5 and the fixing block 6 are rotatably connected, and the through slot 8 and the clamping slot 9 are mutually conductive. When the damaged blade 3 needs to be replaced, pressure is applied to the limit plate 5 to drive the limit plate 5 to start moving in the direction of the fixing block 6, and at the same time, the clamping slot 9 on the limit plate 5 is driven to cancel the clamping connection with the connecting plate 7 and separate from each other, and then the limit plate 5 is driven to start rotating. When the through slot 8 on the limit plate 5 is rotated to be aligned with the connecting plate 7, a pulling force is applied to the limit plate 5 to drive the limit plate 5 and the connecting plate 7 to separate from each other. At this time, several moving The ring 4 loses the restriction of the limit plate 5, thereby achieving the effect of disassembling several mobile rings 4. When several mobile rings 4 need to be installed, several mobile rings 4 are sleeved on the connecting rod 2, and then the through groove 8 on the limit plate 5 is aligned with the connecting plate 7 and pressure is applied to drive the limit plate 5 to penetrate the connecting plate 7, and then the limit plate 5 is rotated to drive the clamping groove 9 on the limit plate 5 to align with the connecting plate 7, and then the clamping groove 9 and the connecting plate 7 are clamped together. At this time, several mobile rings 4 are affected by the limit plate 5 and cannot be separated from the connecting rod 2, thereby achieving the effect of fixing the connecting plate 7 and several mobile rings 4. The connecting plate 7 is arranged in a "cross" shape, which can improve the stability of the connecting plate 7 and the clamping groove 9 when they are clamped together, and at the same time can also improve the positioning effect between the connecting plate 7 and the clamping groove 9 or the through groove 8.

[0027] like Figure 1-Figure 5As shown, the driving assembly includes a limiting ring 10 slidably connected to the side wall of the connecting rod 2, and a placement groove 11 is provided at one end of the rotating rod 1 for the limiting ring 10 to slide. The limiting ring 10 and the placement groove 11 are connected by a spring 12. The side walls of the limiting ring 10 and the placement groove 11 are provided with threaded holes 13, and the threaded holes 13 are connected to the screw rods 14. When it is necessary to remove a number of movable rings 4, pressure is applied to the movable rings 4 toward the limiting ring 10 to drive the limiting ring 10 into the placement groove 11, and the threaded holes 13 on the side walls of the limiting ring 10 and the placement groove 11 are driven to align with each other. At the same time, the spring 12 begins to deform and compress under the influence of pressure, and then drives the screw rod 14 to rotate, and the limiting ring 10 and the placement groove 11 are fixed to each other by the screw rod 14, and then the limiting plate is driven 5 is separated from the connecting plate 7 and several moving rings 4 are replaced. After the replacement is completed, the limiting plate 5 and the connecting plate 7 are fixed to each other, and then the screw rod 14 is rotated again to drive the screw rod 14 and the threaded hole 13 on the limiting ring 10 to separate from each other. At this time, the spring 12 loses its restriction and begins to deform and recover, driving the limiting ring 10 to start moving in the direction of the several moving rings 4 and abut against the several moving rings 4. At this time, the elastic potential energy is released by the spring 12, so that the several moving rings 4 can abut against each other, thereby achieving the effect of driving the several moving rings 4 to abut against each other. When the screw rod 14 enters into the threaded hole 13 on the side wall of the limiting ring 10, the bottom of the limiting ring 10 and the opening of the placement groove 11 are arranged at the same level, which can facilitate the subsequent installation of the moving ring 4 and avoid the moving ring 4 from tilting during installation.

[0028] like Figure 1-Figure 5 As shown, a connecting block 15 is fixedly connected to the inner wall of the moving ring 4, and a sliding groove 16 for the connecting block 15 to slide is provided on the connecting rod 2, which can prevent the moving ring 4 from rotating on the connecting rod 2 and improve the stability of the moving ring 4 on the connecting rod 2.

[0029] The utility model is used normally as follows: when the milling cutter is damaged, pressure is applied to the plurality of movable rings 4 in the direction of the limiting ring 10, driving the limiting ring 10 to enter the placement groove 11, and driving the side wall of the limiting ring 10 to align with the threaded hole 13 of the side wall of the placement groove 11. At the same time, the spring 12 begins to deform and compress under the influence of pressure, and then drives the screw 14 to rotate, and the limiting ring 10 and the placement groove 11 are fixed to each other by the screw 14. At this time, the plurality of movable rings 4 lose their restrictions, driving the plurality of movable rings 4 to cancel the abutment, so that the plurality of movable rings 4 can move on the connecting rod 2. After the abutment between the plurality of movable rings 4 is canceled, the milling cutter as a whole is The limiting plate 5 is flipped over, and a gap appears between the movable rings 4 and the limit plates 5. Subsequently, pressure is applied to the limit plates 5 to drive the limit plates 5 to start moving toward the fixed block 6. At the same time, the card slots 9 on the limit plates 5 are driven to cancel the card connection with the connecting plate 7 and separate from each other. Subsequently, the limit plates 5 are driven to start rotating. When the through slots 8 on the limit plates 5 are rotated to be aligned with the connecting plate 7, a pulling force is applied to the limit plates 5 to drive the limit plates 5 and the connecting plates 7 to separate from each other. At this time, the movable rings 4 lose the restriction of the limit plates 5, and are driven to start moving along the side walls of the connecting rod 2 and separate from the connecting rod 2. Then, the movable rings 4 connected to the damaged blade 3 are taken out and replaced.

[0030] After the replacement is completed, the several moving rings 4 are placed back on the connecting rod 2, and then the through grooves 8 on the limiting plate 5 are aligned with the connecting plate 7 and pressure is applied to drive the connecting plate 7 to start moving along the through grooves 8, and drive the limiting plate 5 to penetrate the connecting plate 7, and then rotate the limiting plate 5 to drive the slots 9 on the limiting plate 5 to align with the connecting plate 7, and then the slots 9 and the connecting plate 7 are engaged with each other. At this time, the several moving rings 4 are affected by the limiting plate 5 and cannot be separated from the connecting rod 2. The several moving rings 4 are fixed to the connecting rod 2, and the screw is rotated again. The rod 14 drives the screw rod 14 and the threaded hole 13 on the limiting ring 10 to separate from each other. At this time, the spring 12 loses its restriction and begins to deform and recover, driving the limiting ring 10 to start moving in the direction of the plurality of movable rings 4 and abutting against the plurality of movable rings 4. At this time, the elastic potential energy is released by the spring 12, and the plurality of movable rings 4 can be abutted against each other, thereby completing the effect of replacing the damaged blade 3. By setting the fixed component, when the milling cutter is damaged, the damaged blade 3 on the milling cutter can be replaced separately, thereby reducing economic losses and reducing manufacturing costs.

[0031] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
