[0002] Fiber cutting tools are specialized tools used for processing fiber materials. Their design and performance directly affect processing quality and efficiency. Fiber cutting tool holders are important tools in the field of fiber material processing, and their design must comprehensively consider the characteristics of fiber materials and the requirements of the cutting process.

[0003] Chinese Patent No. CN207840155U discloses a cutting tool holder, including a mounting bracket, a tool holder, and a tool post. One end of the tool holder is inserted into a mounting hole on the mounting bracket, and the tool holder is detachably connected to the mounting bracket perpendicularly. The other end of the tool holder is fixed to the tool post. The tool post has a mounting groove, and clamping mechanisms are provided on both sides of the tool post on both sides of the mounting groove. Each clamping mechanism includes a circular hole on the tool post and a fastening screw that mates with the circular hole. Angle plates are provided around the mounting hole. A limiting rod is provided at the upper and lower ends of the mounting bracket near the tool holder. The mounting bracket is fixed to a cutting execution device. The advantages of this invention are: the tool holder can be disassembled and installed by tightening and loosening paired fastening screws; different cutting angles can be achieved by rotating the tool holder; it is flexible in application, simple in structure, and highly practical.

[0004] However, the above-mentioned publicly available solutions have the following shortcomings: the existing fiber cutting tool holder structure cannot quickly change tools of different sizes and models, which affects the time required for each tool change, not only increasing the workload of the staff, but also affecting the efficiency of cutting. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art of not being able to quickly change between different sizes and types of cutting tools, and to propose a tool holder structure for fiber cutting tools.

[0006] The technical solution of this utility model is: a tool holder structure for a fiber cutting tool, including a base; and further including:

[0007] The positioning and cooling mechanism is located on the top of the base and is used to drive the tool to perform multi-axis positioning and movement and spray coolant onto the tool when it is in use.

[0008] The mounting mechanism is mounted on the positioning and cooling mechanism and is used to clamp tools of different sizes and types from all directions.

[0009] The rotating disk is located inside the mounting mechanism. It has a hexagonal groove, and a rotating clamp is slidably mounted on the inner side of the groove. A locking block is located on the top of the rotating clamp, and a guide frame is slidably mounted on the outer side of the locking block. Rotating the rotating disk drives the hexagonal groove to rotate. Each side of the hexagonal groove is equipped with a rotating clamp. When the hexagonal groove rotates, it works with the guide frame to drive the six rotating clamps to rotate synchronously, thereby controlling the opening and closing of the rotating clamps. The rotating clamps are used to fix and install the cutting tool in all directions.

[0010] Preferably, the positioning and cooling mechanism includes a positioning component and a cooling component;

[0011] The positioning component is located on the top of the base and is used to move the tool to the machining position via multiple axes;

[0012] The cooling assembly is mounted on the positioning assembly and is used to move with the tool and spray coolant onto the tool when it is in operation.

[0013] Preferably, the positioning assembly includes a tool holder body, an electric slider one, a slide rail one, and an electric slider two;

[0014] The tool holder body is located on the top of the base. Electric slider one is slidably mounted on the tool holder body. Slide rail one is located on the side of electric slider one. Electric slide rail two is slidably mounted on slide rail one. Slide rail two is located on the side of electric slider two. A mounting platform is slidably mounted on slide rail two.

[0015] Preferably, the cooling assembly includes an infusion tube, a nozzle, and a supply tank;

[0016] The infusion tube is located inside the mounting platform, the nozzle is located at the bottom of the infusion tube, and the supply tank is located at the top of the infusion tube.

[0017] Preferably, the infusion tube is a flexible tube that can change shape arbitrarily as the mounting platform moves, and the output end of the nozzle points to the installed fiber cutter.

[0018] Preferably, the mounting mechanism includes a mounting tube, a circular slide rail, a fixing plate, and a spring;

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] 1. Through the installation mechanism, pressing the rotating block drives the rotating clamp to open, thereby installing fiber cutters of different sizes and types. Then, releasing the rotating block, the rotating block is fixed to the fiber cutter under the action of the spring. This can accommodate a variety of cutters to adapt to the processing characteristics of different fiber materials, and can flexibly change cutters according to actual processing needs to meet diverse processing requirements. At the same time, different sizes and types of cutters can be changed directly on the cutter holder without disassembling the entire cutter holder, which greatly shortens the cutter change time and improves the utilization rate and production efficiency of the equipment.

[0022] 2. Through the setting of the positioning and cooling mechanism, the computer controls the electric slider one, electric slider two and the mounting table to move the tool precisely to the appropriate machining position. The nozzle moves with the mounting table, so that it always points to the surroundings of the tool to spray coolant to cool it down. In this way, the computer control can flexibly adjust the tool position to ensure that the tool accurately reaches the working point, realize the machining of complex shapes and fine structures, reduce machining errors caused by positioning deviations, improve machining accuracy, and ensure that all parts of the tool are cooled evenly, effectively reducing the high temperature generated during the cutting process, maintaining the cutting performance of the tool, reducing tool wear and extending the tool life.

[0030] The positioning and cooling mechanism is located on the top of the base 1 and is used to drive the tool to perform multi-axis positioning and to spray coolant onto the tool when it is in use.

[0031] The mounting mechanism is mounted on the positioning and cooling mechanism and is used to clamp tools of different sizes and types from all directions.

[0032] A rotating disk 306 is located inside the mounting mechanism. A hexagonal slide groove 307 is provided on the rotating disk 306.

Each side of the hexagonal slide groove 307 is provided with a rotating clamping plate 309. When the hexagonal slide groove 307 rotates, it cooperates with the guide frame 308 to drive the six rotating clamping plates 309 to rotate synchronously, thereby controlling the opening and closing of the rotating clamping plates 309. The rotating clamping plates 309 are used to fix and install the cutting tool in all directions.

[0033] The positioning and cooling mechanism includes a positioning component and a cooling component; the positioning component is located on the top of the base 1 and is used to move the tool to the machining position via a multi-axis; the cooling component is located on the positioning component and is used to move with the tool and spray coolant onto the tool when the tool is working. The positioning assembly includes a tool holder body 201, an electric slider 1 202, a slide rail 1 203, and an electric slider 2 204. The tool holder body 201 is located on the top of the base 1. The electric slider 1 202 is slidably mounted on the tool holder body 201. There are two electric sliders 1 202 symmetrically arranged about the tool holder body 201. The slide rail 1 203 is located on the side of the electric slider 1 202. The electric slide rail 2 205 is slidably mounted on the slide rail 1 203. The electric slider 2 204 has a slide rail 2 205 on its side. A mounting platform 206 is slidably mounted on the slide rail 2 205. The electric slider 1 202 controls the vertical movement of the fiber cutter, the electric slider 2 204 controls the longitudinal movement of the fiber cutter, and the mounting platform 206 controls the transverse movement of the cutter. Thus, the precise movement of the cutter is controlled by a computer to process the material. The cooling assembly includes a liquid inlet pipe 208, a nozzle 207, and a liquid supply tank 209. The liquid inlet pipe 208 is located inside the mounting platform 206, and the nozzle 207 is located at the bottom of the liquid inlet pipe 208. The nozzle 207 is used to atomize the coolant. The liquid supply tank 209 is located at the top of the liquid inlet pipe 208. The liquid supply tank 209 contains coolant, which can be replenished through a notch at the top of the liquid supply tank 209. When cooling is needed, the liquid supply tank 209 is opened, and the coolant flows through the liquid inlet pipe 208 to the nozzle 207, and then is sprayed from the nozzle 207 onto the cutting tool for cooling.

[0034] The infusion tube 208 is a flexible tube that can change shape arbitrarily as the mounting platform 206 moves, and the output end of the nozzle 207 points to the installed fiber cutter.

[0035] Example 2

[0036] like Figures 3-4 As shown, this utility model proposes a tool holder structure for a fiber cutting tool. Compared with Embodiment 1, this embodiment details the structure of the mounting mechanism.

[0037] The mounting mechanism includes a mounting tube 301, a circular slide rail 302, a fixing plate 303, and a spring 304. The mounting tube 301 is located at the bottom of the mounting platform 206, the circular slide rail 302 is located on the outside of the mounting tube 301, the fixing plate 303 is located on the outside of the mounting tube 301 and above the circular slide rail 302, and the spring 304 is located on the side of the fixing plate 303. A rotating block 305 is provided at the end of the spring 304 away from the fixing plate 303. The side of the rotating block 305 is connected to the outside of the rotating disk 306. Pressing the rotating block 305 allows it to slide on the circular slide rail 302, thereby driving the rotating disk 306 to rotate. The rotating disk 306 controls the rotating clamp 309 to open. After the tool is installed between the six rotating clamps 309, the rotating block 305 is released. The rotating block 305 rebounds under the action of the spring 304, thereby driving the rotating clamp 309 to clamp the tool.

[0038] In summary, when using this utility model, the fiber cutter is installed inside the mounting tube 301, and the rotating block 305 is pressed to slide on the circular slide rail 302, thereby driving the rotating disk 306 to rotate. The rotating disk 306 drives the hexagonal slide groove 307 to rotate. When the hexagonal slide groove 307 rotates, it cooperates with the guide frame 308 to drive the six rotating clamping plates 309 to rotate synchronously, thereby controlling the opening and closing of the rotating clamping plates 309. After the cutter is installed between the six rotating clamping plates 309, the rotating block 305 is released. The rotating block 305 rebounds under the action of the spring 304, thereby driving the rotating clamping plates 309 to rotate. 09. Clamp the cutter. After installation, use the computer to control the electric slider 1 202, electric slider 2 204 and mounting table 206 to start. Electric slider 1 202 controls the vertical movement of the fiber cutter, electric slider 2 204 controls the longitudinal movement of the fiber cutter, and mounting table 206 controls the transverse movement of the cutter. Thus, the computer controls the precise movement of the cutter to process the material. During the processing, open the liquid supply tank 209, and the coolant flows through the liquid delivery pipe 208 to the nozzle 207, and then sprays from the nozzle 207 onto the cutter for cooling.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
