Description

Technical Field

[0001] The utility model relates to the technical field of rotary cutters and discloses a split milling cutter. Background Art

[0002] A milling cutter is a rotary tool used for milling, with one or more teeth, and is mainly used to process planes, steps, grooves, formed surfaces, and cut materials on a milling machine. The milling cutter processes by rotating, has more teeth and no idle travel, so the cutting speed is high, the productivity is high, and the surface roughness is small. There are many types of milling cutters, which can be divided into three categories according to their uses: milling cutters for processing planes, milling cutters for processing grooves, and milling cutters for processing formed surfaces.

[0003] The patent with the patent authorization publication number CN220311882U discloses a milling cutter, including a tool holder for connecting to a machine tool, a tool body fixedly connected to one end of the tool holder away from the machine tool, a guide groove for guiding debris is provided on the tool body, and the edge of the guide groove forms a blade on the tool body; an annular processing groove is provided on the tool body. Although the R angles of the upper and lower ends of the processing groove in the above patent are inwardly concave arc surfaces, when rotating at high speed, the blade body chamfers the edge while cutting close to the material, but when the tool holder is damaged and broken, since the blade body is fixedly connected to the tool holder and the conical blade head is fixedly connected to the blade body, the blade body cannot be removed from the tool holder, and the conical blade head cannot be removed from the blade body, resulting in the entire milling cutter being scrapped.

[0004] Therefore, a split milling cutter is needed. Utility Model Content

[0005] In order to overcome the disadvantage of the existing patent that when the tool holder is damaged and broken, since the tool body is fixedly connected to the tool holder and the tapered tool head is fixedly connected to the tool body, the tool body cannot be removed from the tool holder, and the tapered tool head cannot be removed from the tool body, thereby causing the entire milling cutter to be scrapped, the purpose of the utility model is to provide a split milling cutter.

[0006] The utility model provides the following technical solution: a split milling cutter, comprising a tool rod, a mounting bolt, a mounting head, a first blade and a mounting bolt. The tool rod is provided with a mounting groove, the mounting groove is threadedly provided with a mounting bolt, the mounting bolt is provided with a mounting head, the mounting head is detachably provided with a plurality of first blades, and the first blade is threadedly provided with a mounting bolt.

[0007] As an improvement of the above scheme, it also includes a second blade and a third mounting bolt. The second blade is detachably provided on the mounting cutter head, and the third mounting bolt is threadedly provided on the second blade.

[0008] As an improvement of the above scheme, it also includes a connecting seat, a clamping block and a docking seat. The bottom of the knife rod is fixedly connected to the connecting seat, and the clamping block is arranged on the docking seat, and the clamping block is clamped with the connecting seat.

[0009] As an improvement of the above scheme, it also includes a mounting ring and a material-blocking corrugated plate. The knife rod is provided with a mounting ring, and the mounting ring is threadedly provided with a material-blocking corrugated plate.

[0010] As an improvement to the above solution, a plurality of mounting holes are provided on the mounting cutter head.

[0011] As an improvement of the above solution, the docking seat is located on the output shaft of the motor.

[0012] Compared with the prior art, the utility model provides a split milling cutter, which has the following beneficial effects:

[0013] 1. When the cutter bar breaks, turn the mounting bolt to disengage it from the cutter bar, and then separate the mounting cutter head from the cutter bar, thereby avoiding the entire milling cutter from being scrapped, thereby saving production costs.

[0014] 2. Move the second blade to a suitable position on the mounting head, insert the mounting bolt three into the second blade and tighten it, and then fix the second blade on the mounting head, so that the milling cutter can meet different usage requirements and improve the applicability of the milling cutter.

[0015] 3. By moving the connecting seat forward and the docking seat, and then pushing the connecting seat backward, the clamping block is engaged with the connecting seat, and then the knife rod is fixed on the motor, so as to facilitate the quick connection between the knife rod and the motor.

DETAILED DESCRIPTION

[0021] 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.

[0022] Example 1: A split milling cutter, see Figure 1-Figure 4 , including a knife bar 1, a mounting bolt 13, a mounting head 4, a first blade 5 and a second mounting bolt 6. The knife bar 1 is provided with a mounting groove 2, the mounting groove 2 is threadedly provided with a mounting bolt 13, the mounting bolt 13 is provided with a mounting head 4, the mounting head 4 is detachably provided with five first blades 5, and the first blade 5 is threadedly provided with a second mounting bolt 6. The knife bar 1 is provided with a mounting ring 13, the mounting ring 13 is threadedly provided with a material blocking corrugated plate 14, the waste generated during material processing falls on the material blocking corrugated plate 14, and the waste is conveniently collected in a centralized manner. The mounting head 4 is provided with a plurality of mounting holes 12, the mounting holes 12 are used to install the blade, and the position of the blade is conveniently adjusted to meet different processing requirements.

[0023] When using the milling cutter, first connect the tool rod 1 to the output shaft of the motor, and then turn on the motor. The output shaft of the motor rotates to drive the tool rod 1 to rotate, so that the first blade 5 rotates and contacts the cut material, and then the cut material is processed by rotation. After using the milling cutter for a long time, the first blade 5 will be worn out. By rotating the mounting bolt 6, the first blade 5 can be removed from the first blade 5, which makes it easier to replace the first blade 5. When the tool rod 1 breaks, the mounting bolt 3 is rotated to disengage it from the tool rod 1, and then the mounting cutter head 4 is separated from the tool rod 1, thereby avoiding scrapping of the entire milling cutter, thereby saving production costs.

[0024] Example 2: Based on Example 1, please refer to Figure 2 A second blade 7 is detachably provided on the mounting cutter head 4, and a mounting bolt 3 8 is threadedly provided on the second blade 7.

[0025] When chamfering of the material is required, the second blade 7 is moved to a suitable position of the mounting head 4, the mounting bolt three 8 is inserted into the second blade 7, and the mounting bolt three 8 is tightened to fix the second blade 7 on the mounting head 4, so that the milling cutter can meet different usage requirements and improve the applicability of the milling cutter.

[0026] See also Figure 1 and Figure 3A connecting seat 9 is provided at the bottom of the shank 1 by welding, a clamping block 10 is provided on the docking seat 11, a clamping groove is provided at the bottom of the connecting seat 9, the clamping block 10 is inserted into the clamping groove and connected with the connecting seat 9, and the docking seat 11 is located on the output shaft of the motor.

[0027] Before using the milling cutter, first move the tool rod 1 to a suitable position on the milling machine so that the connecting seat 9 is above the docking seat 11, and then push the connecting seat 9 downward to engage the clamping block 10 with the connecting seat 9, thereby fixing the tool rod 1 on the motor, thereby facilitating quick connection between the tool rod 1 and the motor.
