Abstract
Description
Technical Field
[0001] This application relates to the field of CNC machine tool technology, and more specifically, to a CNC tool holder that prevents tools from falling off. Background Technology
[0002] In the field of modern machining, CNC machine tools have become one of the core equipment in the manufacturing industry due to their high precision and high efficiency. As a key component for CNC machine tools to achieve cutting, the proper storage and management of CNC cutting tools directly affects machining quality, production efficiency, and cost control. Traditional CNC cutting tool placement methods are relatively crude, commonly using simple hook-type, tray-type, or open tool holders.
[0003] A tool holder for CNC machine tools, with publication number CN218776575U, is designed to prevent tools from falling out. This patent uses a storage component that can seal the tool in place through a placement slot and a pressing slot, preventing the tool from falling out during placement, thereby reducing tool damage and extending the tool's service life.
[0004] Although the patent can prevent the knife from falling during placement, when the cover plate on the placement rack is raised, it is still within the space above the placement rack, which may obstruct the operator's view to some extent. This makes it less convenient to accurately place the knife into the corresponding placement slot, requiring more careful positioning. Otherwise, the knife may collide with the edge of the placement slot, affecting the smoothness of knife placement and potentially damaging the knife. Utility Model Content
[0005] To address the aforementioned problems, this application provides a CNC tool holder that prevents tools from falling off.
[0006] The CNC tool holder that prevents tools from falling out, provided in this application, adopts the following technical solution:
[0007] A CNC tool holder for preventing tools from falling out includes two connecting frames, with a placement frame between the two connecting frames, and a sealing cover on the top of the placement frame.
[0008] A sealing assembly is provided between the shelf and the sealing cap;
[0009] The sealing assembly includes two fixing plates, which are fixedly connected to both sides of the placement frame. An electric push rod is rotatably connected to the top of each fixing plate. Plates are fixedly connected to both sides of the sealing cover, and the output ends of the two electric push rods are rotatably connected to the corresponding plate.
[0010] Through the aforementioned technical solution, the rotating opening mechanism of this sealing assembly allows the sealing cover to gradually rotate towards one side of the placement rack during the lifting process, maximizing the central viewing area above the placement rack. When placing or retrieving knives, the operator's view is not significantly obstructed, allowing for clear and direct observation of the placement slot layout within the rack. This enables precise placement of the knives in their corresponding positions, effectively preventing collisions between the knives and the edges of the placement slots, ensuring smooth placement, reducing the risk of damage to the knives due to impacts, and improving operational efficiency.
[0011] Furthermore, two connecting blocks are fixedly connected to the rear side of the placement rack. Rotating rods are rotatably connected inside the two connecting blocks. A connecting plate is fixedly connected to one end of the rotating rod, and the connecting plate is fixedly connected to the sealing cover.
[0012] Furthermore, the two connecting frames have multiple mounting holes inside, and the two ends of the placement frame are connected to the connecting frames by bolts.
[0013] Furthermore, each of the two connecting frames has two casters at its bottom, and a block is fixedly connected to the opposite side of each connecting frame.
[0014] With the above technical solution, when it is necessary to move the entire tool holder, convenient movement can be achieved by relying on the moving wheels at the bottom of the connecting frame.
[0015] Furthermore, both blocks have threaded rods connected internally, and friction pads are fixedly connected to the bottom of both threaded rods.
[0016] With the above technical solution, since the threaded rod is threadedly connected to the block, as it rotates, the threaded rod will gradually move downwards, and the friction pad at its bottom will make close contact with the ground, increasing the friction with the ground, thereby firmly fixing the entire tool holder in place and ensuring the stability of the holder during tool operation.
[0017] Furthermore, the placement rack has multiple placement slots inside, and each of the placement slots has a leakage channel inside.
[0018] Furthermore, the connecting frame has an internal cavity located below the leakage tank, and an inclined plate is fixedly connected to the bottom of the cavity. One end of the placement frame is connected to a liquid storage chamber.
[0019] Furthermore, the liquid storage chamber is located at the lowest end of the inclined plate, and an outlet pipe is connected inside the liquid storage chamber, with a valve inside the outlet pipe.
[0020] Through the above technical solution, this device can effectively collect residual cutting fluid from the cutting tools, preventing it from dripping and polluting the workshop environment, keeping the workshop clean and orderly, reducing safety hazards, and realizing the recycling and reuse of cutting fluid. Then, the cutting fluid in the storage chamber can be discharged with a simple operation of the valve, which is convenient, quick, and saves manpower and time costs.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] (1) The rotating opening method adopted by the sealing component of this utility model allows the sealing cover to gradually rotate to one side of the placement rack during the lifting process, maximizing the central field of view above the placement rack. When the operator places or retrieves the knife, the line of sight will not be obstructed by a large area, and the layout of the placement slots in the placement rack can be clearly and directly observed, allowing the knife to be accurately placed in the corresponding position. This effectively prevents the knife from colliding with the edge of the placement slot, ensuring the smooth placement of the knife, reducing the risk of damage to the knife due to collision, and also improving the operating efficiency.
[0023] (2) This utility model can effectively collect residual cutting fluid from the cutting tool, prevent it from dripping and polluting the workshop environment, keep the workshop clean and orderly, reduce safety hazards, and realize the recycling and reuse of cutting fluid. Then, the cutting fluid in the storage chamber can be discharged simply by operating the valve, which is convenient, quick and saves manpower and time costs. Attached Figure Description

[0030] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0031] Reference Figures 1-5 A CNC tool holder for preventing tools from falling out includes a connecting frame 1, the number of connecting frames 1 is set to two, a placement frame 2 is provided between the two connecting frames 1, and a sealing cover 3 is provided on the top of the placement frame 2;
[0032] A sealing assembly is provided between the placement rack 2 and the sealing cover 3;
[0033] The sealing assembly includes two fixing plates 7. The two fixing plates 7 are fixedly connected to the two sides of the placement frame 2 respectively. The top of each of the two fixing plates 7 is rotatably connected to an electric push rod 9. The two sides of the sealing cover 3 are fixedly connected to plate bodies 8. The output ends of the two electric push rods 9 are rotatably connected to the corresponding plate bodies 8 respectively.
[0034] When it is necessary to open the sealing cover 3 to retrieve or place the knife, the two electric push rods 9 are activated. The electric push rods 9 extend, and since the output end of the electric push rods 9 is rotatably connected to the plates 8 on both sides of the sealing cover 3, and the bottom of the electric push rods 9 is rotatably connected to the top of the fixed plates 7 on both sides of the placement rack 2, as the electric push rods 9 extend, they will push the plates 8 to move outward and upward. Due to the rotatable connection structure design, the rear side of the sealing cover 3 begins to rotate upward and lift around the rotating rod 5. Under the continuous push of the electric push rods 9, the sealing cover 3 slowly opens, and the internal space of the placement rack 2 is gradually revealed to the operator, allowing the operator to clearly and unobstructedly retrieve or place the knife.
[0035] After the tool is retrieved or placed, the sealing cover 3 needs to be closed. At this time, the two electric push rods 9 are activated to retract. The output end of the electric push rod 9 drives the plate 8, which is rotatably connected to it, to move inward and downward. Since the rear side of the sealing cover 3 is rotatably connected to the connecting block 4 of the placement frame 2 through the rotating rod 5, under the combined action of the pulling force of the electric push rod 9 and the rotational support of the rotating rod 5, the sealing cover 3 begins to slowly rotate downward around the rotating rod 5, completing the return of the sealing cover 3.
[0036] The rotating opening mechanism of this sealing assembly allows the sealing cover 3 to gradually rotate towards one side of the placement rack 2 during the lifting process, maximizing the central viewing area above the placement rack 2. When placing or retrieving tools, the operator's view is not significantly obstructed, allowing for a clear and direct observation of the placement slots 15 within the placement rack 2. This enables precise placement of the tools in their corresponding positions, effectively preventing collisions between the tools and the edges of the placement slots 15, ensuring smooth tool placement, reducing the risk of tool damage due to impact, and improving operational efficiency.
[0037] Reference Figures 1-3 Two connecting blocks 4 are fixedly connected to the rear side of the placement rack 2. A rotating rod 5 is rotatably connected inside the two connecting blocks 4. A connecting plate 6 is fixedly connected to one end of the rotating rod 5. The connecting plate 6 is fixedly connected to the sealing cover 3.
[0038] Reference Figures 1-4 The two connecting frames 1 have multiple mounting holes 10 inside. The two ends of the placement frame 2 are connected to the connecting frame 1 by bolts. The bottom of each of the two connecting frames 1 is provided with two moving wheels 11. A block 14 is fixedly connected to the opposite side of each of the two connecting frames 1. A threaded rod 12 is threadedly connected inside each of the two blocks 14. A friction pad 13 is fixedly connected to the bottom of each of the two threaded rods 12.
[0039] The placement frame 2 is connected to the connecting frame 1 by bolts at both ends engaging with the mounting holes 10 inside the connecting frame 1. During installation, align the ends of the placement frame 2 with the corresponding positions on the connecting frame 1, pass the bolts through the mounting holes 10 and tighten them, so that the placement frame 2 is securely fixed between the two connecting frames 1, forming a single integrated structure. If maintenance, replacement or adjustment of the placement frame 2 is required, it can be easily removed by simply unscrewing the bolts.
[0040] When the entire tool holder 2 needs to be moved, it can be easily moved by the casters 11 at the bottom of the connecting frame 1. The casters 11 can roll on the workshop floor, and the operator only needs to apply a small pushing force to push the holder 2 to the designated position.
[0041] Once the tool holder 2 reaches its designated work location, it needs to be secured to prevent it from moving arbitrarily due to accidental collisions, workshop vibrations, or other factors during use. By rotating the threaded rods 12 inside the two blocks 14, which are threadedly connected to the blocks 14, the threaded rods 12 gradually move downwards with rotation. The friction pads 13 at their bottom then come into close contact with the ground, increasing the friction and thus firmly fixing the entire tool holder 2 in place, ensuring its stability during tool operation.
[0042] Reference Figures 1-4The placement rack 2 has multiple placement slots 15 inside, and each placement slot 15 has a leakage groove 16 inside. The connecting rack 1 has a cavity inside, which is located below the leakage groove 16. An inclined plate 17 is fixedly connected to the bottom of the cavity. One end of the placement rack 2 is connected to a liquid storage chamber 18, which is located at the lowest end of the inclined plate 17. An outlet pipe 19 is connected inside the liquid storage chamber 18, and a valve 20 is provided inside the outlet pipe 19.
[0043] When a used CNC tool is placed in the placement slot 15 of the placement rack 2, the residual cutting fluid on the tool surface will flow down the drain groove 16 at the bottom of the placement slot 15 under the influence of gravity. Since the connecting frame 1 has a cavity located below the drain groove 16, the cutting fluid will drip into the cavity.
[0044] Guided by the inclined plate 17 at the bottom of the cavity, the cutting fluid flows to the lowest end of the inclined plate 17. One end of the placement rack 2 is connected to a storage chamber 18, which is located at the lowest end of the inclined plate 17. The cutting fluid eventually gathers in the storage chamber 18. When it is necessary to clean the cutting fluid collected in the storage chamber 18, the operator only needs to open the valve 20 inside the outlet pipe 19. Under the action of gravity and liquid pressure, the cutting fluid in the storage chamber 18 will be smoothly discharged through the outlet pipe 19, completing the cutting fluid recycling process.
[0045] Working principle: In the initial state, the sealing cover 3 tightly covers the top of the placement rack 2, and the knife is safely stored inside. When the operator needs to retrieve or place the knife, first activate the two electric push rods 9 in the sealing assembly to extend them. Since the bottom of the electric push rod 9 is rotatably connected to the top of the fixing plates 7 on both sides of the placement rack 2, and the output end is rotatably connected to the plates 8 on both sides of the sealing cover 3, as the electric push rod 9 extends, it pushes the plates 8 to move outward and upward, thereby causing the rear side of the sealing cover 3 to rotate upward around the rotating rod 5 as the axis. This rotation opening method cleverly allows the sealing cover 3 to gradually rotate towards one side of the placement rack 2 during the lifting process, maximizing the central field of vision above the placement rack 2, allowing the operator to see the layout of the placement slot 15 inside the placement rack 2 without obstruction and operate the knife accurately.
[0046] The placement frame 2 is securely connected to the mounting holes 10 inside the connecting frame 1 via bolts at both ends. If the placement frame 2 requires maintenance, it can be disassembled and replaced. The casters 11 at the bottom of the connecting frame 1 facilitate the movement of the entire placement frame 2. With a small push from the operator, it can roll to the designated location on the workshop floor. Upon reaching the designated location, to ensure stability, the threaded rods 12 inside the two blocks 14 are rotated. Because the threaded rods 12 are threadedly connected to the blocks 14, their bottom friction pads 13 move downwards with the rotation, making close contact with the ground, increasing friction and preventing the placement frame 2 from moving due to external forces.
[0047] When the used CNC cutting tool is placed into the placement slot 15 inside the placement rack 2, the residual cutting fluid on the tool surface flows under gravity along the drain groove 16 at the bottom of the placement slot 15 to the cavity below it inside the connecting frame 1. Then, guided by the inclined plate 17 at the bottom of the cavity, it flows to the storage chamber 18 at one end of the placement rack 2. When it is necessary to clean the cutting fluid, the valve 20 inside the outlet pipe 19 is opened, and the cutting fluid in the storage chamber 18 is smoothly discharged under the action of gravity and liquid pressure, completing the entire operation process. This ensures tool safety while also being environmentally friendly and efficient. After the tool operation is completed, the electric push rod 9 is activated to retract, and the sealing cover 3 is closed in the reverse process of opening, continuing to protect the tool.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
