[0029] 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.

[0030] See also Figure 1-Figure 4 The utility model provides the following technical solutions: a multi-station milling cutter disc assembly, including a milling cutter disc body 1 and a milling blade 2, with an assembly hole 11 at the center of the milling cutter disc body 1, a plurality of milling cutter seat bodies 12 evenly spaced along the circumferential direction are fixed on the circumferential surface of the milling cutter disc body 1, the milling blade 2 is fixed on the milling cutter seat body 12, and also includes: a clamping plate 3, a No. 1 locking bolt 4 and a No. 2 locking bolt 5.

[0031] Further, by Figure 1-Figure 3 As shown, in this embodiment, an I-shaped plug 31 is fixed on the clamping plate 3, and a No. 2 T-shaped slot 22 and a No. 1 T-shaped slot 124 are respectively provided on the tail end of the milling blade 2 and the milling cutter seat body 12 for the I-shaped plug 31 to be embedded. A No. 1 threaded hole 122 is provided on the milling cutter seat body 12, and a No. 1 locking bolt 4 penetrates the clamping plate 3 and is screwed into the No. 1 threaded hole 122 by threaded screwing. The milling cutter seat body 12 has a mounting groove 121 for the milling blade 2 to be embedded, and a No. 2 threaded hole 123 is provided in the mounting groove 121. The milling blade 2 has a through hole 21, and a No. 2 locking bolt 5 penetrates the clamping plate 3 and the through hole 21 and is screwed into the No. 2 threaded hole 123 by threaded screwing. After adopting the above scheme, when using, when installing the milling blade 2, first place the milling blade 2 in the mounting groove 121. The second T-slot 22 and the first T-slot 124 are connected to the pressing plate 3, and the I-shaped plug 31 is embedded in the second T-slot 22 and the first T-slot 124. Finally, the first locking bolt 4 is passed through the pressing plate 3 and screwed into the first threaded hole 122 by threaded engagement, and the second locking bolt 5 is passed through the pressing plate 3 and the through hole 21 and screwed into the second threaded hole 123 by threaded engagement. The installation and fixation of the milling blade 2 can be achieved. The I-shaped plug 31, the second T-slot 22 and the first T-slot 124 form a mortise and tenon structure, which can limit the milling blade 2 from different directions, greatly improving the stability of the installation of the milling blade 2 and reducing the amplitude of the jitter. Therefore, the first locking bolt 4 and the second locking bolt 5 are not easy to loosen, and the overall stability performance is relatively high.

[0032] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the I-shaped plug 31 is tightly fitted with the inner walls of the No. 2 T-slot 22 and the No. 1 T-slot 124. After the I-shaped plug 31 is embedded in the No. 2 T-slot 22 and the No. 1 T-slot 124, there is no gap between the outer wall of the I-shaped plug 31 and the inner walls of the No. 2 T-slot 22 and the No. 1 T-slot 124, which reduces the amplitude of the jitter and improves the stability.

[0033] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the outer wall of the milling blade 2 fits tightly against the inner wall of the mounting groove 121. After the clamping plate 3 is locked, the clamping plate 3 will squeeze the milling blade 2. There is no gap between the milling blade 2 and the inner wall of the mounting groove 121 and the clamping plate 3, thereby reducing the amplitude of the jitter and improving the stability.

[0034] Preferably, by Figure 1 and Figure 2As shown, in this embodiment, the thickness of the milling blade 2 is equal to the width of the mounting groove 121, ensuring that the clamping plate 3 can reliably limit the milling blade 2 so that there is no gap between the milling blade 2 and the clamping plate 3.

[0035] Preferably, by Figure 1-Figure 3 As shown, in this embodiment, it also includes: a rubber anti-skid pad 6, which is bonded and fixed to the inner wall of the mounting groove 121. The rubber anti-skid pad 6 is flexible. After locking the milling blade 2 and the clamping plate 3, the rubber anti-skid pad 6 shrinks to further improve the stability of the installation of the milling blade 2.

[0036] It is worth noting that, as mentioned above, the thickness of the milling blade 2 is equal to the width of the mounting groove 121. At this time, after locking the clamping plate 3, the rubber anti-slip pad 6 will inevitably shrink, and the reverse elastic force of the rubber anti-slip pad 6 will also reversely squeeze the milling blade 2, and cooperate with the clamping plate 3 to achieve the function of clamping the milling blade 2, thereby improving the stability of the milling blade 2. In addition, due to the reverse elastic force of the rubber anti-slip pad 6, it can also effectively increase the bite force of the thread between the No. 2 locking bolt 5 and the No. 2 threaded hole 123, thereby preventing the No. 2 locking bolt 5 from loosening.

[0037] Preferably, by Figure 1-Figure 4 As shown, in this embodiment, it also includes: anti-slip ridges 61, multiple anti-slip ridges 61 are evenly fixed on the rubber anti-slip pad 6, the anti-slip ridges 61 provide an anti-slip function, and after locking the clamping plate 3, the anti-slip ridges 61 shrink to further prevent the milling blade 2 from slipping, thereby ensuring the stability of the installation of the milling blade 2.

[0038] Preferably, by Figure 1 As shown, in this embodiment, the milling cutter disc body 1 and the milling cutter seat body 12 are forged integral components with high structural strength.

[0039] It should be noted that the above scheme is only a preferred implementation scheme of the present invention and is not used to limit the present invention. In the absence of special needs, the milling disc body 1 and the milling seat body 12 are preferably forged one-piece components with high structural strength. If necessary, the milling seat body 12 can also be fixedly connected to the milling disc body 1 by conventional means, such as using bolts to fix the milling seat body 12 to the milling disc body 1 to achieve detachable installation of the milling seat body 12.

[0040] Components not described in detail herein are prior art.

[0041] Working principle and use process of the utility model: When the milling cutter disc assembly of the utility model is used, when installing the milling cutter blade 2, the milling cutter blade 2 is first placed in the installation groove 121, and the through hole 21 is made to correspond to the No. 2 threaded hole 123, and then the clamping plate 3 is placed on the front side of the milling cutter blade 2, so that the I-shaped plug block 31 is embedded in the No. 2 T-shaped slot 22 and the No. 1 T-shaped slot 124, and finally the No. 1 locking bolt 4 is passed through the clamping plate 3 and then screwed into the No. 1 threaded hole 122 by threaded screwing, and the No. 2 locking bolt 5 is passed through the clamping plate 3 and the through hole 21 and then screwed into the No. 2 threaded hole 123 by threaded screwing, so that the installation and fixation of the milling cutter blade 2 can be achieved;

[0042] The utility model utilizes the I-shaped plug block 31, the second T-shaped slot 22 and the first T-shaped slot 124 to form a mortise and tenon structure, which can limit the milling blade 2 from different directions, greatly improving the stability of the installation of the milling blade 2 and reducing the amplitude of the jitter. Therefore, the first locking bolt 4 and the second locking bolt 5 are not easy to loosen, and the overall stability performance is relatively high.
