When working, each tooth cuts off the excess of the workpiece intermittently in turn. Milling cutters are mainly used to process planes, steps, grooves, formed surfaces and cut off workpieces on milling machines. Disc milling cutters, as a type of face milling cutter, are mainly used for cutting step surfaces and grooves. When processing mechanical parts, a milling cutter disc installed on the corresponding machine tool is often used to process the surface of the part, and this is to ensure that the processed parts have a high-precision plane.

[0035] 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.

[0036] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a multi-station milling cutter disc with adjustable blade angle, comprising a milling cutter disc main body 1, a plurality of milling cutter holders 2 installed on the milling cutter disc main body 1 at equal intervals along the circumferential direction, and milling blades 3 fixed on the milling cutter holder 2, the milling cutter disc main body 1 having an adjustment port 11 for the milling cutter holder 2 to pass through, and also comprising: a cylinder 21, a gear 7 and a driving mechanism 9.

[0037] Further, by Figure 1 As described, in this embodiment, the cylinder 21 is fixed to the tail end of the milling cutter holder 2 and is rotatably connected to the milling cutter disc body 1 by means of a No. 1 mounting shaft rod 6, and teeth 211 are fixed on the cylinder 21, and the gear 7 is rotatably connected to the milling cutter disc body 1 by means of a No. 2 mounting shaft rod 8 and meshes with the teeth 211, and the driving mechanism 9 is drivably connected to the gear 7 for driving the gear 7 to rotate. After adopting the above scheme, when in use, the milling cutter disc body 1 is driven by the power components of the machine tool, and the cutting work is performed by the milling blade 3. When necessary, the driving mechanism 9 is started to drive the gear 7 to rotate, and the gear 7 drives the milling cutter holder 2 to rotate through the meshing action, and can synchronously adjust the angles of multiple milling blades 3 to meet different processing needs, and there is no need to disassemble the milling blade 3, and the adjustment is more convenient.

[0038] Optionally, by Figure 1-Figure 3 As described, in this embodiment, the driving mechanism 9 includes: a worm gear 91, a mounting ear with a hole 92, a worm 93 and a driving motor 94. The worm gear 91 is fixed on the second mounting shaft 8. The two mounting ears with a hole 92 are symmetrically fixed in the milling cutter disc body 1. The worm 93 is rotatably installed between the two mounting ears with a hole 92 and meshes with the worm gear 91. The driving motor 94 is fixed on the mounting ear with a hole 92 and is used to drive the worm 93 to rotate. After adopting the above scheme, when in use, start the driving motor 94 to drive the worm 93 to rotate. The worm 93 drives the worm wheel 91 to rotate through the meshing action.

After adopting the above scheme, the milling blade 3 is fixedly installed by the locking bolt 10. While ensuring stable installation, it is also convenient to disassemble and replace the damaged milling blade 3.

[0044] Preferably, by Figure 1 , Figure 2 and Figure 4 As described above, in this embodiment, the outer wall of the milling blade 3 is tightly fitted to the inner wall of the mounting opening 22 , thereby ensuring the stability of the installation of the milling blade 3 and preventing the milling blade 3 from shaking.

[0045] Optionally, by Figure 1As shown, in this embodiment, it also includes: a flange 4 and a fixing rod 5. The flange 4 is fixed to the top of the milling cutter body 1, and the fixing rod 5 is fixed to the top surface of the flange 4. After adopting the above scheme, the fixing rod 5 is connected to the machine tool power component by conventional means, and is driven by the machine tool power component.

[0046] It should be noted that the drive motor 94 is a conventional device purchased on the market with a built-in power switch. Technicians in this field can make a conventional selection according to usage requirements. Its working principle is common knowledge known to technicians in this field and has been fully disclosed in the prior art, so it will not be elaborated in this article.
