Description

Technical Field

[0001] This utility model belongs to the field of heat shrink tool holder technology, specifically a novel combined heat shrink tool holder. Background Technology

[0002] Heat shrink tool holders are high-performance tool clamping systems that utilize the principle of thermal expansion and contraction of metals to clamp tools. This is a very popular tool holder technology in high-precision, high-speed machining fields (such as precision molds, aerospace, and medical parts processing). Because it eliminates intermediate components like collets and nuts, its simple and symmetrical structure provides extremely high clamping accuracy, improving machining efficiency. It is suitable for high-precision, high-speed, and high-hardness machining. However, in existing heat shrink tool holders, the insertion length of the tool's insert pin into the heat shrink tool holder is not fixed during assembly, making it difficult to ensure the correct insertion depth. This can easily lead to insufficient clamping length by the heat shrink tool holder, and under high-speed rotation and cutting forces, the tool may be pulled out or fly off entirely. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a novel combined heat shrink tool holder, which solves the problem that when heat shrink tool holders and tools are assembled, the length of the tool's insertion pin inserted into the heat shrink tool holder is not fixed, making it difficult to ensure the tool insertion depth. This can easily lead to insufficient clamping length of the heat shrink tool holder for the tool, and under the action of high-speed rotation and cutting force, the tool may be pulled out or fly off completely.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a novel combined heat-shrink knife handle, comprising a knife handle body, a knife clamping section fixedly connected to the bottom of the knife handle body, an installation cylinder provided inside the knife clamping section, a through-hole groove provided inside the installation cylinder, two protrusions symmetrically fixedly connected to the inner wall of the through-hole groove, an insertion post installed inside the through-hole groove, a knife head fixedly connected to the insertion post extending from the bottom of the insertion post into the through-hole groove, connecting grooves provided on both sides of the insertion post inside the through-hole groove, the inner wall of the connecting groove being in close contact with the protrusions, a through groove provided at the bottom end of the insertion post inside the through-hole groove, and a limit bolt threadedly connected to the bottom end of the surface of the installation cylinder, the limit bolt corresponding to the position of the through groove.

[0005] As a further embodiment of this utility model: a mounting ring is fixedly installed at the bottom of the tool clamping section, and screws are symmetrically threaded through both sides of the mounting ring.

[0006] As a further embodiment of this utility model: one end of the screw passes through the mounting ring and extends to the outside of the mounting ring, where a knob is fixedly connected; a movable plate is provided inside the mounting ring on the side of the screw away from the knob, and the movable plate is slidably connected to the inner wall of the mounting ring.

[0007] As a further embodiment of this utility model: a limiting block is fixedly connected to the side of the movable plate away from the screw, and the limiting block is slidably connected through the inside of the mounting ring.

[0008] As a further embodiment of this utility model: the tool clamping section has an installation groove inside, and the installation cylinder is in close contact with the installation groove.

[0009] As a further embodiment of this utility model: symmetrical insertion strips are provided on both sides of the mounting cylinder, and the insertion strips are tightly attached to the mounting groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel combined heat shrink tool holder, by setting up a plug-in post, through groove, protrusion and limiting bolt, aligns the connecting grooves on both sides of the plug-in post with the protrusion, moves the plug-in post to insert into the plug-in groove, and at the same time drives the connecting groove and the protrusion to insert, so that the through groove is aligned with the limiting bolt, and rotates the limiting bolt to pass through the through groove and connect with the mounting cylinder, thereby realizing the insertion and fixing of the plug-in post to the surface of the mounting cylinder, avoiding the possibility that the tool may be pulled out or fly off completely under high-speed operation due to insufficient tool clamping length.

[0011] This novel combined heat-shrink tool holder, by incorporating a screw, knob, limit block, and connector strip, allows the mounting cylinder and connector strip to be inserted together into the mounting groove at the bottom of the tool clamping section. Rotating the knob then drives the screw to move, causing the screw to move a movable plate. This allows the movable plate to move the limit block into the mounting groove, where it abuts against the connector strip, thus fixing the mounting cylinder inside the mounting groove and completing the fixed installation of the tool clamping section and the mounting cylinder.

[0013] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0014] like Figure 1-3As shown, this utility model provides a technical solution: a novel combined heat shrink knife handle, including a knife handle body 1, a knife clamping section 2 fixedly connected to the bottom of the knife handle body 1, an installation ring 3 fixedly installed at the bottom of the knife clamping section 2, and screws 4 symmetrically threaded through both sides of the installation ring 3. By setting the screws 4, rotating the knob 5 can drive the screws 4 to rotate, causing the screws 4 to push the movable plate 6 and the limiting block 7 to move together. The limiting block 7 can limit the insertion strip 10. One end of the screw 4 passes through the mounting ring 3 and extends to the outside of the mounting ring 3, where a knob 5 is fixedly connected. The side of the screw 4 away from the knob 5 is located inside the mounting ring 3 and a movable plate 6 is provided. The movable plate 6 is slidably connected to the inner wall of the mounting ring 3. By providing the movable plate 6, when the screw 4 moves, the screw 4 can drive the movable plate 6 to slide inside the mounting ring 3, so that the movable plate 6 can stably drive the limit block 7 to move. A limiting block 7 is fixedly connected to the side of the movable plate 6 away from the screw 4. The limiting block 7 is slidably connected to the inside of the mounting ring 3. By setting the limiting block 7, the limiting block 7 moves out of the movable plate 6 and is pressed against the bottom of the plug strip 10, thereby fixing the plug strip 10 inside the mounting groove 8. The tool clamping section 2 has an installation groove 8 inside, and the installation cylinder 9 is in close contact with the installation groove 8. By setting the installation groove 8, the installation cylinder 9 is inserted into the installation groove 8, thereby installing the tool head 17 at the bottom of the tool clamping section 2. The mounting cylinder 9 is symmetrically provided with plug strips 10 on both sides. The plug strips 10 are close to the mounting groove 8. By setting the plug strips 10, the plug strips 10 are inserted into the mounting groove 8 together with the mounting cylinder 9, so that the mounting groove 8 limits the mounting cylinder 9 through the plug strips 10. The tool clamping section 2 is equipped with an installation cylinder 9. An insertion groove 11 is opened through the installation cylinder 9. Two protrusions 12 are symmetrically fixedly connected to the inner wall of the insertion groove 11. An insertion post 13 is installed inside the insertion groove 11. The bottom of the insertion post 13 extends out of the insertion groove 11 and is fixedly connected to the tool head 17. By setting the protrusions 12, when the insertion post 13 is inserted into the insertion groove 11, the protrusions 12 slide and connect with the connecting groove 14, so that the protrusions 12 limit the insertion post 13 through the connecting groove 14, so that the insertion post 13 through the groove 15 aligns with the limiting bolt 16. The plug-in post 13 is located inside the plug-in groove 11 and has connecting grooves 14 on both sides. The inner wall of the connecting groove 14 is close to the protrusion 12. The bottom end of the plug-in post 13 inside the plug-in groove 11 has a through groove 15. The bottom end of the surface of the mounting cylinder 9 is threadedly connected to a limit bolt 16. The limit bolt 16 is positioned corresponding to the through groove 15. By setting the limit bolt 16, the limit bolt 16 is inserted into the through groove 15, thereby fixing the plug-in post 13, so that the cutter head 17 and the plug-in post 13 can be fixed at the bottom of the mounting cylinder 9.

[0015] The working principle of this utility model is as follows: After aligning the connecting grooves 14 on both sides of the insertion post 13 with the protrusions 12 inside the insertion groove 11, move the insertion post 13 to insert it into the mounting cylinder 9. Simultaneously, the insertion post 13 drives the connecting grooves 14 to install with the protrusions 12. As the insertion post 13 continues to move, it aligns the through groove 15 with the limiting bolt 16. Then, rotate the limiting bolt 16 to insert it into the through groove 15, thus fixing the insertion post 13 inside the mounting cylinder 9. This fixes the cutter head 17 to the bottom of the mounting cylinder 9. The cutting head 17 and the mounting cylinder 9 are heated so that the mounting cylinder 9 clamps the cutting head 17, completing the installation of the cutting head 17. The insert strips 10 on both sides of the mounting cylinder 9 are aligned with the mounting groove 8. The mounting cylinder 9 is moved so that it is inserted into the top of the mounting groove 8. The knob 5 is rotated, which drives the screw 4 to rotate. The screw 4 drives the limiting block 7 to move out of the mounting ring 3 through the movable plate 6, so that the limiting block 7 abuts against the insert strip 10, thereby fixing the cutting head 17 and the mounting cylinder 9 at the bottom of the tool clamping section 2.
