[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1:

[0038] Please see Figure 1-5 A tool holder machining device for diamond end mills, comprising:

[0039] The support plate 1 has a linear guide rail 2 fixedly connected to its top end. A displacement plate 3 is slidably connected to the linear guide rail 2. A detachable grinding plate 4 is provided at the top end of the displacement plate 3.

[0041] Transmission component 6 is assembled at the end of displacement plate 3 away from limit component 5, and is used to cooperate with displacement plate 3 to drive grinding plate 4 to move towards the reset position.

[0042] Tool holder support assembly 7 is assembled on one side of the top of the support plate 1 and is used to mount the tool holder of the milling cutter;

[0043] Please refer to Figure 1 In this embodiment, a plurality of linear sliders are fixedly connected to the bottom end of the displacement plate 3, and the displacement plate 3 is connected to the outside of the linear guide rail 2 through the linear sliders.

[0044] More specifically, by setting the linear slider, it can work with the linear guide rail 2 to guide the displacement of the displacement plate 3, thereby ensuring the stability of the displacement plate 3 in application;

[0045] Please refer to Figure 1 In this embodiment, the top of the displacement plate 3 is provided with a receiving groove, and the grinding plate 4 is slidably connected inside the receiving groove.

[0046] More specifically, the arrangement of the receiving groove allows the top of the displacement plate 3 to have space for mounting the grinding plate 4.

[0047] Furthermore, both sides of the grinding plate 4 are fixedly connected with limit strips, and the receiving groove is provided with a limit groove that is compatible with the limit strips. The limit strips are also slidably connected inside the limit grooves. Through the setting of the limit grooves and limit strips, the assembly path of the grinding plate 4 can be guided to avoid the grinding plate 4 from moving uncontrollably at the displacement plate 3.

[0048] Please refer to Figure 3In this embodiment, the limiting component 5 includes:

[0049] Extension block 8 is fixedly connected to one end of displacement plate 3. A guide shaft 9 is rotatably connected to the middle of extension block 8. A threaded section 10 is provided on the outer side of one end of guide shaft 9. A stabilizing plate 11 is threadedly connected to the outer side of threaded section 10.

[0050] The baffle 12 is fixedly connected to the other end of the guide shaft 9. The top end of the baffle 12 is fixedly connected to the extension frame 13. The top end of the extension frame 13 is fixedly connected to the insertion rod 14. The grinding plate 4 has an insertion hole 15 at one end near the insertion rod 14, and the insertion rod 14 is also snapped into the inside of the insertion hole 15.

[0051] Please refer to Figure 4 In this embodiment, the transmission assembly 6 includes:

[0052] Linkage plate 16 is fixedly connected to the end of displacement plate 3 away from extension block 8, and linkage through groove 17 is provided in the middle of linkage plate 16.

[0053] The transmission seat 18 is fixedly connected to the top of the bearing plate 1. The top of the transmission seat 18 is fixedly connected to the transmission motor 19. The output end of the transmission motor 19 is fixedly connected to the eccentric plate 20. The end of the eccentric plate 20 away from the transmission motor 19 is fixedly connected to the guide rod 21, and the guide rod 21 is also movably connected inside the linkage slot 17.

[0054] Example 2:

[0055] Please see Figure 5 This embodiment provides a technical solution based on Embodiment 1: the tool holder support assembly 7 includes:

[0056] The positioning plate 22 is fixedly connected to one side of the top of the bearing plate 1. A bracket 23 is fixedly connected to the top of the bearing plate 1 near the positioning plate 22. Both ends of the top of the bracket 23 are slidably connected to linear guide rods 24.

[0057] The movable limiting plate 25 is fixedly connected between the bottom ends of the two linear guide rods 24. The top of the fixed limiting plate 22 and the bottom of the movable limiting plate 25 are both provided with multiple positioning grooves 26.

[0058] The transmission screw 27 is threadedly connected to the middle of the top of the bracket 23, and one end of the transmission screw 27 located inside the bracket 23 is also rotatably connected to the middle of the moving limit plate 25.

[0059] Please refer to Figure 5 In this embodiment, the placement groove 26 is arc-shaped, and multiple support holes are provided on the placement groove 26, with alloy balls movably connected inside each support hole.

[0060] More specifically, through the shape characteristics of the placement groove 26, it can have a wider range of contact with the cutter shank of the milling cutter. With the setting of the ball bearing, after the cutter shank of the milling cutter is formed by the fixed limit plate 22 and the moving limit plate 25, the contact between the grinding plate 4 and the cutter shank can drive the cutter shank to rotate adaptively under the support of the fixed limit plate 22 and the moving limit plate 25.

[0061] Please refer to Figure 5 In this embodiment, the outer side of the transmission screw 27 is threaded with an anti-rotation plate 28, and the bottom end of the anti-rotation plate 28 is provided with anti-slip texture.

[0062] More specifically, by setting the anti-rotation plate 28, when the transmission screw 27 is not in the transmission state, rotating the anti-rotation plate 28 will cause the anti-rotation plate 28 to approach the bracket 23 until the anti-rotation plate 28 is in contact with the moving limit plate 25, thereby increasing the friction force of the transmission screw 27 and preventing the transmission screw 27 from rotating uncontrollably.

[0063] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0064] Working principle: First, the cutter shank is properly placed inside the positioning groove 26 at the fixed limit plate 22. Then, the transmission screw 27 is rotated. With the connection between the transmission screw 27 and the bracket 23, the transmission screw 27 can push the moving limit plate 25 close to the fixed limit plate 22 under the limit of the linear guide rod 24, until the cutter shank is limited between the fixed limit plate 22 and the moving limit plate 25 and comes into contact with the grinding plate 4.

[0065] The drive motor 19 is started to drive the eccentric plate 20 to rotate. With the connection between the eccentric plate 20 and the guide rod 21, as the guide rod 21 rotates with the eccentric plate 20, the displacement plate 3 will be driven to move back to the reset position under the limit of the linear guide rail 2 by the adjustment of the guide rod 21 inside the linkage slot 17.

[0066] During the contact between the grinding plate 4 and the tool holder, the tool holder will rotate adaptively at the return groove 26 due to the influence of friction. Thus, the tool holder is effectively ground under the continuous contact between the grinding plate 4 and the tool holder.

[0067] Furthermore, when the application effect of the grinding plate 4 is not good, first rotate the stabilizing plate 11 to cause the stabilizing plate 11 to move along the thread section 10. When the stabilizing plate 11 is separated from the contact with the extension block 8, the friction of the guide shaft 9 can be reduced. Then pull up the stop bar 12 to cause the stop bar 12 to flip upward until the insertion rod 14 moves out of the insertion hole 15, thereby unlocking the grinding plate 4. Then the grinding plate 4 can be pulled out from the displacement plate 3 and replaced.
