Description

Technical Field

[0001] This invention relates to a tool holder, specifically a composite material tool holder, belonging to the field of tool clamping technology. Background Technology

[0002] A machine tool is a machine used to manufacture machines; it is also called a machine tool or machine tool machine, and is commonly referred to simply as a machine tool. The machinery industry typically uses gray cast iron, which has good wear resistance and vibration damping properties, to manufacture the machine tool body. Machine tools are generally divided into metal cutting machine tools, forging and pressing machine tools, and woodworking machine tools, etc. Parts requiring high precision and fine surface roughness generally need to be finally machined on a machine tool using cutting methods. Machine tools play a significant role in the modernization of the national economy. Cutting tools are essential equipment in the field of machine tool processing. They are used to perform turning operations on metal materials. Generally, the tail of the cutting tool needs to be mounted on a tool holder, which is then mounted on the machine tool equipment for normal machining operations.

[0003] In the prior art, such as the combined tool holder disclosed in CN219598719U, the tool holder, tool post, baffle, fixing plate, reinforcing pad, through groove, sealing gasket, and fixing components are used in combination to increase the friction between the tool holder and the baffle, increase resistance, and prevent the tool holder from shaking inside the tool post, thereby improving the stability and firmness of the combined connection between the tool holder and the tool post.

[0004] However, in implementing the relevant technology, the above-mentioned combined tool holder design has the following problems: In the prior art, the stability of installation can be improved by the cooperation of components such as the tool holder. However, in actual use, due to the different lengths of the tools, but the position of the machine tool tool holder is fixed and cannot be flexibly adjusted, if the tool is too long, the machine tool needs to be started to adjust the position before the tool position is reserved, which makes the installation more troublesome. In view of this, a combined composite material tool holder is provided to overcome the above defects. Summary of the Invention

[0005] To address the problem that excessively long cutting tools require machine tool adjustment before installation can be made, resulting in cumbersome installation, this invention provides a composite material tool holder.

[0006] The present invention achieves the above objectives through the following technical solution: a combined composite material knife handle, including a power end, a connecting sleeve connected below the power end, and a protruding rod extending from the bottom end of the connecting sleeve, a chuck fixed below the protruding rod, and a positioning mechanism provided inside the connecting sleeve; The positioning mechanism includes a support rod, which is fixed to the outer wall of one end of the protruding rod located inside the connecting sleeve. A sliding rod protrudes from the inside of the support rod. A sliding groove is provided on the inner wall of the connecting sleeve, and a slot is provided on one side of the sliding groove. A positioning hole is provided on the outer wall of the connecting sleeve at the position corresponding to the slot. A pressure ring is slidably connected to the upper part of the outer wall of the connecting sleeve.

[0007] As a further embodiment of the present invention: the support rod and the sliding rod form a sliding structure, and the support rod and the sliding groove form a sliding structure.

[0008] As a further embodiment of the present invention: the lower pressure ring is threadedly connected to the connecting sleeve, and the connecting sleeve and the through rod form a sliding structure.

[0009] As a further embodiment of the present invention: a locking ring is sleeved below the pressure ring on the outer wall of the connecting sleeve, and a locking hole is opened on the inner wall of the locking ring corresponding to the position of the sliding rod. A limit rod is fixed at the bottom end of the locking ring, and a support ring is rotatably connected below the limit rod.

[0010] As a further embodiment of the present invention: an abutting mechanism is provided on the upper part of the inside of the connecting sleeve, the abutting mechanism including a fixing shell, the fixing shell being fixed to the top of the inside of the connecting sleeve, and a positioning block protruding from the inside of the fixing shell.

[0011] As a further embodiment of the present invention: the abutting mechanism further includes a limiting plate, the limiting plate is fixed at one end of the positioning block that penetrates the fixing shell, and the limiting shell is sleeved on the outside of the limiting plate. An electromagnet is fixed at the top of the limiting shell, and a placement hole is opened at the top of the protruding rod corresponding to the position of the positioning block.

[0012] As a further embodiment of the present invention: the limiting plate and the limiting shell form a sliding structure, and the limiting plate is magnetically connected to the electromagnet.

[0013] The beneficial effects of this invention are as follows: the through rod slides along the connecting sleeve, allowing the support rod to slide along the groove. After moving to the corresponding height, it enters the slot for initial limiting. Subsequently, the internal spring of the support rod pushes the sliding rod through the positioning hole for further limiting. The lower pressure ring and the threaded connection of the connecting sleeve are in contact and press the sliding rod together, thereby achieving stability after limiting. This allows the tool holder to be adjusted or disassembled as needed when clamping the tool, thus improving applicability. By turning the support ring, the locking ring is supported by the limiting rod, allowing the locking hole to limit the sliding rod. The locking ring and the lower pressure ring are in contact to further improve the stability of the sliding rod's limiting. When the through rod enters the connecting sleeve, the positioning block passes through the fixing shell and enters the placement hole for limiting. The electromagnet is activated to push the limiting plate with the same magnetic pole to slide along the limiting shell, thereby resisting the through rod and the limiting of the slot and positioning hole, which can improve the stability of the through rod after positioning.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. Example 1

[0017] like Figures 1 to 5As shown, a composite material knife handle includes a power end 1, a connecting sleeve 2 connected to the lower part of the power end 1, a protruding rod 3 extending from the bottom end of the connecting sleeve 2, a chuck 4 fixed below the protruding rod 3, and a positioning mechanism 5 disposed inside the connecting sleeve 2. The positioning mechanism 5 includes a support rod 501, which is fixed to the outer wall of the end of the protruding rod 3 located inside the connecting sleeve 2. A sliding rod 502 extends from the inside of the support rod 501. A groove 503 is formed on the inner wall of the connecting sleeve 2, a slot 504 is formed on one side of the groove 503, and a positioning hole 505 is formed on the outer wall of the connecting sleeve 2 corresponding to the slot 504. A pressure ring 506 is slidably connected to the upper part of the outer wall of the connecting sleeve 2. A sliding structure is formed between support rod 501 and sliding rod 502, and a sliding structure is formed between support rod 501 and sliding groove 503. The lower pressure ring 506 is threadedly connected to connecting sleeve 2, and a sliding structure is formed between connecting sleeve 2 and through rod 3. Through rod 3 slides along connecting sleeve 2, allowing support rod 501 to slide along sliding groove 503. After moving to the corresponding height, it enters slot 504 for initial limiting. Then, the spring inside support rod 501 pushes sliding rod 502 through positioning hole 505 for further limiting. With the lower pressure ring 506 threadedly connected to connecting sleeve 2, it adheres to and presses sliding rod 502, thereby achieving stability after limiting. This allows the tool holder to be adjusted or disassembled as needed when clamping the tool, thus improving applicability. Example 2

[0018] In addition to all the technical features in Embodiment 1, this embodiment also includes: a locking ring 6 is fitted below the pressure ring 506 on the outer wall of the connecting sleeve 2; a locking hole 7 is provided on the inner wall of the locking ring 6 corresponding to the position of the sliding rod 502; a limit rod 8 is fixed to the bottom end of the locking ring 6; a support ring 9 is rotatably connected below the limit rod 8; an abutment mechanism 10 is provided at the upper part of the interior of the connecting sleeve 2; the abutment mechanism 10 includes a fixed shell 1001, which is fixed to the top end of the interior of the connecting sleeve 2; a positioning block 1002 protrudes from the interior of the fixed shell 1001; the abutment mechanism 10 also includes a limiting plate 1003, which is fixed to the end of the positioning block 1002 that penetrates the fixed shell 1001; a limiting shell 1004 is fitted outside the limiting plate 1003; and an electromagnet is fixed to the top end of the limiting shell 1004. 1005. A mounting hole 1006 is provided at the top of the through rod 3 corresponding to the position of the positioning block 1002. The limiting plate 1003 and the limiting shell 1004 form a sliding structure. The limiting plate 1003 is magnetically connected to the electromagnet 1005. By turning the support ring 9, the locking ring 6 is supported by the limiting rod 8, allowing the locking hole 7 to limit the sliding rod 502. The locking ring 6 and the pressing ring 506 are in contact to further improve the stability of the limiting of the sliding rod 502. When the through rod 3 enters the connecting sleeve 2, the positioning block 1002 passes through the fixing shell 1001 and enters the mounting hole 1006 for limiting. The electromagnet 1005 is activated to push the limiting plate 1003 with the same magnetic pole to slide along the limiting shell 1004, thereby resisting the limiting of the through rod 3 in conjunction with the locking groove 504 and the positioning hole 505, which can improve the stability of the through rod 3 after positioning.

[0019] Working principle: The machine tool and power end 1 are connected to the connecting sleeve 2. The chuck 4 at the top of the through rod 3 facilitates the fixed connection with the tool, thus forming a tool holder. The through rod 3 slides stably along the slide groove 503 of the connecting sleeve 2 via the support rod 501, and enters the corresponding slot 504 for initial positioning as needed. The spring inside the support rod 501 pushes the sliding rod 502 through the positioning hole 505 for repositioning and improving connection stability. The pressure ring 506, which is threaded to the connecting sleeve 2, abuts against the sliding rod 502 to increase stability. The locking ring 6 locks the sliding rod 502 through the locking hole 7. The positioning is limited, and the support ring 9, which is threaded to the connecting sleeve 2, is rotated and connected to the locking ring 6 via the limiting rod 8, thereby improving the positioning stability of the sliding rod 502. When the through rod 3 enters the connecting sleeve 2, the positioning block 1002 passes through the fixing shell 1001 and enters the placement hole 1006 for limiting. At the same time, the electromagnet 1005 works to push the limiting plate 1003 with the same magnetic pole to slide along the limiting shell 1004, so that the positioning block 1002 abuts against the placement hole 1006, which cooperates with the positioning hole 505 to position the sliding rod 502, thereby maintaining the positioning stability of the through rod 3.
