Detailed Embodiment

[0014] The technical solutions in the present utility model will be further described below with reference to the drawings and embodiments.

[0015] As Figure 1 and Figure 2As shown in the figure, an earthquake-resistant milling cutter includes a milling cutter rod body 1 and a milling cutter body 2, and is characterized in that: a connecting groove 3 is opened in the milling cutter rod body 1, a connecting member 4 inserted into the connecting groove 3 is fixedly arranged on the milling cutter body 2, two opposite connecting components are arranged between the connecting member 4 and the milling cutter rod body 1, an abutting groove 5 and two first inserting grooves 6 are opened on the connecting member 4, the two first inserting grooves 6 are oppositely arranged on both sides of the abutting groove 5, a damping shock absorber 7 and two first inserting blocks 8 are fixedly arranged in the connecting groove 3, the two first inserting blocks 8 are oppositely arranged on both sides of the damping shock absorber 7, the damping shock absorber 7 is inserted into the abutting groove 5, and the two first inserting blocks 8 are correspondingly inserted into the two first inserting grooves 6, an installation head 9 for connecting with a machine tool is fixedly arranged on the milling cutter rod body 1, and the damping shock absorber 7 is a prior art.

[0016] During the use of the utility model, an operator inserts the connecting member 4 into the connecting groove 3, thereby realizing the insertion of the damping shock absorber 7 and the first inserting block 8 into the connecting member 4. At the same time, through the connection of the connecting components, the stability of the connecting member 4 is also increased, making the connection between the milling cutter body 2 and the milling cutter rod body 1 closer, making the accuracy of the milling cutter body 2 higher and the processing effect better.

[0017] As Figure 1 and Figure 2 shown in the figure, the connecting component includes an installation cavity 10, a rotating block 11 and a sleeve 12 arranged in the installation cavity 10. The installation cavity 10 is arranged on one side of the connecting groove 3 and a through hole 13 is communicated between the two. A limiting cavity 14 located above the connecting groove 3 is arranged on one side of the installation cavity 10. A rotatable limiting member 15 is arranged in the limiting cavity 14. The rotating block 11 is arranged on the milling cutter rod body 1 and is opposite to the installation cavity 10. A threaded rod 16 that rotates through the installation cavity 10 is fixedly arranged on the rotating block 11. One end of the threaded rod 16 away from the rotating block 11 rotates into the installation cavity 10 and is fixedly connected to the limiting member 15 therein. The rod sections of the threaded rod 16 passing through the milling cutter rod body 1 are all smooth rod sections. The sleeve 12 is threadedly sleeved on the threaded rod 16. An L-shaped connecting rod 17 is fixedly arranged on the sleeve 12. A connecting block 18 is fixedly arranged on the connecting rod 17. A positioning groove 19 opposite to the through hole 13 is opened on the connecting member 4. The connecting block 18 can pass through the through hole 13 and be inserted into the positioning groove 19. A first bolt 20 is screwed into the milling cutter rod body 1. The first bolt 20 threadedly passes through the milling cutter rod body 1 and is threadedly connected to the connecting block 18. A first spring 21 fixedly connected to the connecting rod 17 is fixedly arranged on the inner wall of the installation cavity 10. As Figure 1 and Figure 2As shown, a limiting block 22 is fixedly arranged on the bushing 12, a limiting groove 23 is arranged at the top of the installation cavity 10, and the limiting block 22 is slidably arranged in the limiting groove 23. When the connecting piece 4 is inserted into the connecting groove 3, the operator rotates the two rotating blocks 11 respectively. Each rotating block 11 drives the threaded rod 16 and the limiting piece 15 thereon to rotate, so that the bushing 12 on the threaded rod 16 moves back and forth. The connecting block 18 is driven by the connecting rod 17 to slide through the through hole 13 and is inserted into the positioning groove 19. Then, two first bolts 20 are screwed in, so that the two first bolts 20 are threaded through the milling cutter bar body 1 and correspondingly threadedly connected with the two connecting blocks 18. During this process, the limiting block 22 on each bushing 12 is slidably arranged in the relative limiting groove 23. This design method is convenient for the positioning and installation between the milling cutter bar body 1 and the milling cutter body 2, and the structure is simple and easy to operate. Also, through the elastic expansion and contraction of the first spring 21 on the connecting rod 17, the bushing 12 and the threaded rod 16 are tightly connected, so that the bushing 12 can drive the connecting block 18 to move smoothly in the installation cavity 10. Furthermore, when the connecting block 18 is inserted into the positioning groove 19, it can be tightly abutted, making the connection effect between the milling cutter body 2 and the milling cutter bar body 1 better.

[0018] As Figure 1 , Figure 2 and Figure 3 shown, a positioning piece 24 with a hollow structure inside is fixedly arranged on the milling cutter bar body 1. The positioning piece 24 is located below the rotating block 11. A clamping groove 25 is opened at the bottom of the rotating block 11, a clamping hole 26 opposite to the clamping groove 25 is opened at the top of the positioning piece 24. A pulling block 27 is arranged at the bottom of the positioning piece 24. A pull rod 28 vertically upward and slidably passing through the positioning piece 24 is fixedly arranged on the pulling block 27. A positioning block 29 is fixedly arranged at the top end of the pull rod 28. A clamping block 30 passing through the clamping hole 26 and clamped in the clamping groove 25 is fixedly arranged on the positioning block 29. A second spring 31 fixedly arranged on the inner bottom wall of the positioning piece 24 is wound around the pull rod 28. The top end of the second spring 31 is fixedly connected with the bottom of the positioning block 29. A second bolt 32 threadedly connected with the positioning block 29 is arranged through the positioning piece 24. After the connecting block 18 is clamped with the positioning groove 19, the operator stops rotating the rotating block 11. At this time, the notch of the clamping groove 25 faces downward and is opposite to the clamping hole 26. Then, the second spring 31 pushes the clamping block 30 through the positioning block 29, so that the clamping block 30 vertically passes through the clamping hole 26 and is arranged in the clamping groove 25. Then, the second bolt 32 is screwed in, so that the second bolt 32 is threaded through the positioning piece 24 and threadedly connected with the positioning block 29. This design method is convenient for rotating or clamping the rotating block 11, so that the connecting block 18 can be smoothly inserted into the positioning groove 19, and the structure is simple and the effect is good.

[0019] AsFigure 1 and Figure 2 As shown in Figure 2 , a chip guard plate 33 is fixedly arranged on the cutter bar body 1, an annular rubber pad 34 is fixedly arranged on the chip guard plate 33, the connecting piece 4 passes through the central hole of the rubber pad 34, two second inserting blocks 35 which are relatively arranged on both sides of the connecting piece 4 and pass through the rubber pad 34 are fixedly arranged on the chip guard plate 33, and two second inserting grooves 36 are formed at the bottom of the cutter bar body 1. The two second inserting blocks 35 are correspondingly inserted into the two second inserting grooves 36. As Figure 1 and Figure 2 shown in Figure 2 , two damping ring sleeves 37 are embedded in the connecting groove 3. When the cutter bar body 1 and the cutter body 2 are connected and installed, the two second inserting blocks 35 are correspondingly inserted into the two second inserting grooves 36. This design method is convenient for reducing the vibration between the connecting piece 4 and the cutter bar body 1, making the machining accuracy of the cutter body 2 higher and the effect better.

[0020] Working principle:

[0021] First, the operator inserts the connecting piece 4 into the connecting groove 3, so that the connecting piece 4 passes through the two damping ring sleeves 37, and the damping shock absorber 7 is inserted into the abutting groove 5. The two first inserting blocks 8 are correspondingly inserted into the two first inserting grooves 6, and the two second inserting blocks 35 are correspondingly inserted into the two second inserting grooves 36. At this time, the bottom of the cutter bar body 1 abuts against the rubber pad 34.

[0022] After that, the operator rotates the two rotating blocks 11 respectively. Each rotating block 11 drives the threaded rod 16 and the limiting member 15 thereon to rotate, so that the sleeve 12 on the threaded rod 16 moves back and forth. The connecting block 18 is driven by the connecting rod 17 to slide through the through hole 13 and is inserted into the positioning groove 19. Then, the two first bolts 20 are screwed in, so that the two first bolts 20 are threaded through the cutter bar body 1 and are correspondingly threadedly connected to the two connecting blocks 18. During this process, the limiting blocks 22 on each sleeve 12 all slide in the relative limiting grooves 23, and the first spring 21 elastically pushes and stretches the connecting rod 17, which not only makes the connection between the sleeve 12 and the threaded rod 16 tight, but also enables the sleeve 12 to drive the connecting block 18 to move smoothly in the installation cavity 10, so that the connecting block 18 can tightly abut when inserted into the positioning groove 19.

[0023] Then, the operator stops rotating the rotating block 11. At this time, the notch of the clamping groove 25 faces downward and is opposite to the clamping hole 26. After that, the second spring 31 pushes the clamping block 30 through the positioning block 29, so that the clamping block 30 vertically passes through the clamping hole 26 and is inserted into the clamping groove 25. Then, the second bolt 32 is screwed in, so that the second bolt 32 is threaded through the positioning member 24 and is threadedly connected to the positioning block 29. Then, the operator installs the connected cutter on the machine tool through the installation head 9 for milling processing.

[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
