Description

Technical Field

[0001] The utility model relates to the field of cutting tools, in particular to a self-locking cutting tool system. Background Art

[0002] In a self-locking cutting tool system, the tool bit can be automatically locked on the tool shank after installation or adjustment. The self-locking mechanism can ensure that the tool bit will not loosen or fall off due to external vibration or other factors during use, improving the stability and safety of the cutting tool.

[0003] After retrieval, the existing Chinese patent publication number is: CN217452278U, a quick self-locking drill bit and tool shank, including: an irregular cylinder and two alloy drill bit parts, and a first horizontal positioning plane is provided at the bottom of the alloy drill bit part; a first radial positioning plane is provided at the rear end of the chisel edge part and the spiral cutting edge away from the rake face; a V-shaped boss for interference fit connection extends outward from the side wall of the irregular cylinder; the tool shank for clamping and locking a quick self-locking drill bit includes: a second radial positioning surface for abutting and matching with the first radial positioning surface is provided on the side wall of the secondary positioning block, and a second horizontal positioning surface is provided on the primary positioning block; a V-shaped arc-shaped positioning groove is provided at the position where the guiding arc surface is connected to the rod seat; by splitting the traditional high-speed steel drill bit or the integral alloy drill bit into an alloy drill bit part and a tool shank part, the cost is reduced compared with the integral alloy drill bit; at the same time, this structure can quickly disassemble, replace, clamp and self-lock the alloy drill bit, and has strong popularization significance for repeated clamping.

[0004] In the specific implementation of the above patent, the V-shaped boss at the bottom of the alloy drill bit is aligned with the second chip removal groove. Due to the irregular cylinder, the side close to the first chip removal groove is lower than the cylinder surface, so the drill bit can be easily placed into the clamping part of the tool shank. After being placed, the first horizontal positioning plane contacts the second horizontal positioning plane; at this time, the clamping part of the customized tool is placed into the card slot, and the drill bit is rotated clockwise by the customized tool. Because the side of the irregular cylinder near the boss is a standard cylinder surface, the gap between the standard cylinder surface and the lower guiding arc surface of the tool shank is small during the tightening process (the unilateral gap is 0.02 - 0.05 mm, preferably 0.05 mm), which has a certain guiding and positioning effect. While rotating and tightening, the upper surface of the V-shaped boss is in interference fit with the upper surface of the V-shaped arc-shaped positioning groove until the first radial positioning plane of the alloy drill bit contacts the second radial positioning plane of the tool shank, then the self-locking is completed. In this patent, because the rotation direction of the drill bit is the same as the self-locking direction and the V-shaped boss is tightened by interference fit, the alloy drill bit is safe to use and will not fall off. However, in this patent, only a single drill bit can be locked. In the case of needing to use multiple drill bits for processing simultaneously, the frequency of tool replacement and adjustment will increase, resulting in an increase in downtime during the production process and a reduction in production efficiency and working efficiency.

[0024] As Figure 1 - Figure 3 and Figure 4 shown, the release component includes a rotation knob 10, a release slot 11, and a second push spring 12. The outer side of the rotation knob 10 is slidably connected to the inside of the rotation groove 9. The rotation knob 10 is designed to push the latch 6 so that the latch 6 engages in the card slot 4 to lock the tool 3. The release slot 11 is opened in the rotation knob 10. The release slot 11 is designed to facilitate the entry of the latch 6 into it to unlock the tool 3. The bottom end of the second push spring 12 is fixedly connected to the inner bottom end of the rotation groove 9. The second push spring 12 is designed to push up the rotation knob 10 so that the release slot 11 and the latch 6 are not at the same horizontal height. The outer side of the rotation groove 9 is in contact with the outer side of the latch 6. The rotation groove 9 is designed to facilitate the accommodation of the release component. The top end of the second push spring 12 is fixedly connected to the inner bottom end of the rotation knob 10. The second push spring 12 is designed to push up the rotation knob 10 so that the release slot 11 and the latch 6 are not at the same horizontal height.

[0025] An indicating arrow 14 is fixedly connected to the top end of the rotation knob 10. The indicating arrow 14 is designed to facilitate the indication of the position of the release slot 11. A limiting ring 15 is fixedly connected to the outer side of the rotation knob 10. The limiting ring 15 is designed to limit the rotation knob 10. The outer side of the latch 6 is slidably connected to the inside of the card slot 4. The latch 6 is designed to lock the tool 3 by engaging with the card slot 4.

[0026] Working principle: When it is necessary to lock the cutting tool 3 inside the rod body 1, turn the turning knob 10 by hand and press down the turning knob 10 at the same time, so that the turning groove 9 aligns with an indicating groove 13, and the release groove 11 will align with the clamping strip 6. The clamping strip 6 at this position will enter the inside of the release groove 11 under the push of the pushing spring 7 to push the pushing ring 8. At this time, the cutting tool 3 can be placed into the placing groove 2 aligned with the turning groove 9. Then turn the turning knob 10. Because the clamping strip 6 is clamped in the release groove 11 at an inclined angle, the turning knob 10 will squeeze the clamping strip 6 into the clamping groove 4 of the just-placed cutting tool 3. Repeating the above operations can lock the four cutting tools 3. After locking the four cutting tools 3, release the turning knob 10, and the turning knob 10 will rise under the push of the pushing spring 2 12, avoiding being at the same level as the clamping strip 6. By locking multiple cutting tools 3, the frequency of replacing the cutting tool 3 can be reduced, the downtime during the production process can be minimized, and the production efficiency and working efficiency can be improved.
