Description

Technical Field

[0001] This utility model relates to the field of mica tape cutting tool technology, and in particular to a quick-change holder for a fire-resistant mica tape cutting tool. Background Technology

[0002] Fire-resistant mica tape is an insulating material made of mica. It has excellent high-temperature resistance and flame retardant properties. Mica is a natural mineral with good electrical insulation and thermal stability. Fire-resistant mica tape is commonly used in motors, transformers, generators, and other equipment that require high-temperature insulation. It is a very important industrial material and is widely used in fields that require high temperature and insulation protection. Fire-resistant mica tape is usually supplied in roll form. Different equipment or applications have specific requirements for the size and shape of the insulating material. Cutting ensures that the material can be properly adapted to the structure and size of various equipment, thereby achieving better insulation effect. Cutting tools are used during the cutting process.

[0003] In existing technologies, most cutting tools for refractory mica tape are fixed on a base, which makes them inconvenient to replace. After a period of use, the cutting tools need to be removed for maintenance to ensure cutting accuracy and quality. If the disassembly and assembly are difficult, more time and effort will be required, reducing the overall efficiency of maintenance work. Therefore, it is necessary to design a quick-change base for refractory mica tape cutting tools to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a quick-change holder for refractory mica tape cutting tools.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A quick-change holder for refractory mica tape cutting cutters includes a cutter shaft. A plurality of equally spaced cutting cutters are fixedly connected to the outer wall of the cutter shaft. Rotary shafts are fixedly connected to both sides of the cutter shaft. A groove is formed on the rotating shaft, and a bearing is installed within the groove. The inner ring of the bearing is fixedly connected to the rotating shaft. The rotating shaft and the bearing are fitted with the same fixed seat. A fixed block is provided on the top of the fixed seat. Slots are formed on both sides of the fixed block, and pins are installed within the slots. An L-shaped plate is fixedly connected to one side of the pin. Two guide rods pass through the L-shaped plate and are slidably connected to it. The two guide rods are fixedly connected to the same fixed plate, which is fixedly connected to the fixed seat. A fixed shaft is fixedly connected to one side of the L-shaped plate. A roller is fitted onto the fixed shaft and rotatably connected to it. A movable plate is fitted onto the roller, and a slanted groove is formed on the movable plate. The roller is positioned within the groove. Fixed rods are fixedly connected to the bottom of the two movable plates on the same side. The bottom is fixedly connected to the same lifting plate. By lowering the lifting plate to remove the pin from the slot and raising the lifting plate to insert the pin into the slot, the pin can restrict the position of the fixing block, ensuring stability between the fixing block and the fixing seat. This allows for the installation of the cutter. Removing the pin from the slot releases the restriction, allowing the fixing block to be removed from the fixing seat, and thus the cutter can be removed. This effectively solves the problems mentioned in the background art, where most cutting tools for refractory mica tape are fixed to the fixing seat, making replacement inconvenient. After a period of use, the cutting tool needs to be removed for maintenance to ensure cutting accuracy and quality. If disassembly and assembly are difficult, it requires more time and effort, reducing the overall efficiency of maintenance work. This invention achieves simple operation; the fixing and unfixing of the tool can be completed by the lifting action of the lifting plate, reducing operational complexity, facilitating tool disassembly and assembly, and effectively improving the overall efficiency of maintenance work.

[0006] As a further embodiment of this utility model, round rods are inserted through both ends of the lifting plate, the lifting plate is slidably connected to the round rods, a fixed seat is fixedly connected to the bottom of the round rods, and a spring is sleeved on the round rods.

[0007] As a further embodiment of this utility model, a limiting sleeve is provided on the rotating shaft, and the limiting sleeve is fixed to the rotating shaft by screws.

[0008] As a further embodiment of this utility model, two positioning grooves are provided at the top of both ends of the fixing base, and a positioning rod is provided in the positioning groove. The positioning rod is fixedly connected to the bottom of the fixing block, and the positioning rod is adapted to the positioning groove.

[0009] As a further embodiment of this utility model, the top of the fixing base has two limiting grooves, and a limiting rod is provided in the limiting groove, the limiting rod being adapted to the limiting groove.

[0010] As a further embodiment of this utility model, the limiting rod is fixedly connected to the outer wall of the outer ring of the bearing.

[0011] The beneficial effects of this utility model are as follows: By employing a technique where lowering the lifting plate allows the pin to be removed from the slot, and raising the lifting plate allows the pin to be inserted into the slot, the pin insertion into the slot restricts the position of the fixing block, ensuring stability between the fixing block and the fixing seat. This allows for the installation of the cutting tool. Removing the pin from the slot releases the restriction, allowing the fixing block to be removed from the fixing seat, and thus the cutting tool can be detached. This effectively solves the problems mentioned in the background art, where most cutting tools for cutting refractory mica tape are fixed to the fixing seat, making replacement inconvenient. Furthermore, cutting tools need to be removed for maintenance after a period of use to ensure cutting accuracy and quality. If disassembly and assembly are difficult, it requires more time and effort, reducing the overall efficiency of maintenance work. This technique achieves simple operation, allowing the fixing and unfixing of the cutting tool to be completed through the raising and lowering of the lifting plate, reducing operational complexity, facilitating tool disassembly and assembly, and effectively improving the overall efficiency of maintenance work.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1-7A quick-change holder for refractory mica tape cutting tools includes a cutter shaft 1. A plurality of equally spaced cutting blades 101 are fixedly connected to the outer wall of the cutter shaft 1. Rotating shafts 102 are fixedly connected to both sides of the cutter shaft 1. Grooves are formed on the rotating shafts 102, and bearings 2 are installed within these grooves. The inner wall of the inner ring of the bearings 2 is fixedly connected to the rotating shafts 102. The rotating shafts 102 and bearings 2 are fitted onto the same fixing seat 3. A fixing block 4 is provided on the top of the fixing seat 3. Slots 5 are formed on both sides of the fixing block 4, and pins 6 are installed within the slots 5. An L-shaped plate 7 is fixedly connected to one side, and two guide rods 8 pass through the L-shaped plate 7. The L-shaped plate 7 is slidably connected to the guide rods 8, and the two guide rods 8 are fixedly connected to the same fixed plate 22. The fixed plate 22 is fixedly connected to the fixed seat 3. A fixed shaft 9 is fixedly connected to one side of the L-shaped plate 7, and a roller 10 is sleeved on the fixed shaft 9. The roller 10 is rotatably connected to the fixed shaft 9, and a movable plate 11 is sleeved on the roller 10. An inclined groove 12 is opened on the movable plate 11, and the roller 10 is set in the inclined groove 12. The bottoms of the two movable plates 11 on the same side are fixedly connected to a fixed seat 3. The fixed rod 13 has a common lifting plate 14 fixedly connected to its bottom. By lowering the lifting plate to remove the pin from the slot and raising the lifting plate to insert the pin into the slot, the pin can restrict the position of the fixed block, ensuring stability between the fixed block and the fixed seat, allowing the cutter to be installed. Removing the pin from the slot releases the restriction, allowing the fixed block to be removed from the fixed seat, and the cutter to be detached. This effectively solves the problem mentioned in the background art where most cutting tools for refractory mica tape are fixed to the fixed seat, making replacement inconvenient. After a period of use, the cutting tool needs to be removed for maintenance to ensure cutting accuracy and quality. If disassembly and assembly are difficult, it requires more time and effort, reducing the overall efficiency of maintenance work. This invention achieves simple operation, allowing the tool to be fixed and unfixed simply by raising and lowering the lifting plate, reducing operational complexity, facilitating tool disassembly and assembly, and effectively improving the overall efficiency of maintenance work.

[0016] In this embodiment, both ends of the lifting plate 14 are provided with round rods 15, the lifting plate 14 is slidably connected to the round rods 15, the bottom of the round rods 15 is fixedly connected to the fixing seat 3, and the round rods 15 are sleeved with springs 16. When the lifting plate 14 moves up and down, it will move along the round rods 15 to ensure the stability of the lifting plate 14 when it moves. The elastic force of the springs 16 enables the lifting plate 14 to return to its original position when it is not subjected to external force.

[0017] In this embodiment, a limiting sleeve 17 is fitted on the rotating shaft 102, and the limiting sleeve 17 is fixed on the rotating shaft 102 by screws.

[0018] In this embodiment, two positioning grooves 19 are provided at the top of both ends of the fixed base 3. A positioning rod 18 is provided in the positioning groove 19. The positioning rod 18 is fixedly connected to the bottom of the fixed block 4. The positioning rod 18 is adapted to the positioning groove 19. By inserting the positioning rod 18 into the positioning groove 19, the position between the fixed block 4 and the fixed base 3 can be positioned to ensure the accuracy of assembly.

[0019] In this embodiment, the top of the fixed base 3 has two limiting grooves 21, and a limiting rod 20 is provided in the limiting groove 21. The limiting rod 20 is adapted to the limiting groove 21. By inserting the limiting rod 20 into the limiting groove 21, the outer ring of the bearing 2 will not rotate when the cutter shaft 1 rotates, thus playing a limiting role.

[0020] In this embodiment, the limiting rod 20 is fixedly connected to the outer wall of the outer ring of the bearing 2.

[0021] Working principle: During assembly, the operator can step on the lifting plate 14 to lower it. The lifting plate 14 will descend along the round rod 15, causing the spring 16 to contract. The descent of the lifting plate 14 will drive the fixed rod 13 to descend, which in turn will drive the moving plate 11 to descend. The moving plate 11 will apply pressure to the roller 10, causing the roller 10 to move along the inclined groove 12, thus moving the two rollers 10 away from each other. The rollers 10 will then drive the fixed shaft 9 to move, which in turn will drive the L-shaped plate 7 to move along the guide rod 8. The L-shaped plate 7 will then drive the pins 6 to move, moving the two pins 6 away from each other. The rotating shaft 102 and bearing 2 can then be placed on the fixed seat 3, and the limiting rod 20 can be inserted into the limiting groove 21 for limiting. Then, the fixing block 4 is installed, and the positioning rod 18 is inserted. Positioning is performed within the positioning groove 19, causing the fixing block 4 to contact the fixing seat 3. At this time, the pin 6 and the slot 5 are coaxial, allowing the lifting plate 14 to be released. The contracted spring 16 will then extend, causing the lifting plate 14 to rise. The lifting plate 14 will then drive the fixing rod 13 to rise, which in turn will drive the moving plate 11 to rise. The moving plate 11 will then apply pressure to the roller 10 again, causing the two rollers 10 to move closer together. This will bring the two pins 6 closer together until they are inserted into the slot 5, thus restricting the position of the fixing block 4 and completing the assembly. To disassemble, step on the lifting plate 14 again to lower it, allowing the pin 6 to be removed from the slot 5, thus releasing the restriction on the fixing block 4 and separating it from the fixing seat 3. The cutter shaft 1 can then be removed.

[0022] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
