Description

Technical Field

[0001] This utility model relates to the field of machining technology, specifically to a tool storage device for CNC machine tools. Background Technology

[0002] Machining tool storage devices are specialized equipment used to store various cutting tools in a standardized manner, aiming to improve tool management efficiency and extend tool life. Their structures often employ layered drawers, grid slots, or hanging designs to accommodate different specifications of cutting tools such as turning tools, milling cutters, and drill bits. Some devices feature custom grooves or clamps to prevent tools from shaking or bumping. The devices are typically made of wear-resistant steel or engineering plastics, and some are moisture-proof and dust-proof. Some drawers have label bars or QR codes for quick identification of tool models and uses. Reducing manual searching time and preventing cutting edge wear, these devices are fundamental auxiliary equipment for maintaining a clean machining environment and ensuring tool precision. For example, utility model patent CN218194084U discloses a tool storage and retrieval mechanism for machining, including a base and a storage box. The storage box is fixedly connected to the base, and a storage cavity is opened on the top of the storage box. A placement plate is slidably connected inside the storage cavity, and a first compression spring is provided between the placement plate and the storage box. In this utility model, pressing the push plate moves the push column, which in turn moves the transmission slider, which in turn moves the locking block, causing the limiting teeth to retract into the mounting cavity. The placement plate rises under the action of the first compression spring, ejecting the tool for easy retrieval by the operator. The device can be operated with one hand, making it convenient to use. However, this utility model cannot flexibly adjust the tool-taking angle according to the processing environment, and this mechanism concentrates all the tools together, making the tools mixed up and inconvenient to use when changing tools. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a tool storage device for CNC machine tools, solving the technical problems of existing devices being unable to flexibly adjust the tool retrieval angle according to the machining environment, and the inconvenience of tool handling due to all tools being concentrated in one place during tool changes. This resolves the problems mentioned in the background section.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a tool storage device for CNC machine tools, comprising a first storage box, a second storage box connected to the first storage box via a rotating shaft fixing seat, a main storage rail slidably connected inside the first storage box, an auxiliary handle fixedly installed on the upper wall of the main storage rail, a plurality of sliding limiting grooves formed on the front wall of the auxiliary handle, a plurality of storage slots formed inside the main storage rail, a tool storage structure for storing tools slidably installed in one storage slot, the tool storage structure comprising a tool storage box slidably connected to the storage slot, a support plate fixedly installed on the front wall of the tool storage box, a guide rod fixedly installed on the upper wall of the support plate, a limiting block fixedly installed on the upper end of the guide rod, a limiting pressure plate slidably connected to the guide rod below the limiting block, and a reset spring fitted on the guide rod to press the limiting pressure plate against the limiting block.

[0005] Preferably, the first storage box has a spring groove, an adjusting pressure plate is slidably installed in the spring groove, a limit plate is fixedly installed on the upper wall of the adjusting pressure plate, and two spring limit rods are fixedly installed on the lower wall inside the spring groove. Support springs that push the adjusting pressure plate against the upper wall inside the spring groove are fitted on the two spring limit rods.

[0006] Preferably, when the support spring presses the adjusting plate against the upper wall inside the spring groove, the limiting plate extends out of the upper wall of the first storage box from the spring groove. The length of the adjusting plate is greater than that of the spring groove, and the two ends extend out of the spring groove by the same distance.

[0007] Preferably, the connecting end of the second storage box has three slots that can be connected to the limiting plate, the opening end inside the second storage box is fixedly installed with a knife fixing bracket, and the lower wall inside the second storage box is fixedly installed with a cushioning pad.

[0008] Preferably, two auxiliary limiting grooves are provided on the wall surface of the opening end of the second storage box, two magnetic suction grooves are provided on the front wall surface of the first storage box, two auxiliary limiting rods are fixedly installed on the auxiliary handle and respectively inserted into the two auxiliary limiting grooves, and magnetic blocks that are attracted to the two magnetic suction grooves are also fixedly installed on the auxiliary handle.

[0009] Preferably, the knife storage box is equipped with a die mold spring pad sponge, and the die mold spring pad sponge has a groove customized according to the shape of the knife to prevent shaking.

[0010] Preferably, an observation window is fixedly installed on the upper wall of the first storage box to confirm the position of the target tool.

[0011] Beneficial effects This utility model provides a tool storage device for CNC machine tools, which has the following advantages: By aligning the target slot of the second storage box with the limiting plate, releasing the adjusting pressure plate, the support spring elastically resets, and pushing the adjusting pressure plate to drive the limiting plate into the slot, the angle of the second storage box is fixed. The tool retrieval direction can be flexibly adjusted according to different spaces. When the slot corresponds to a certain degree, the space occupied is minimized, making it easy to carry. This solves the problem that existing tool storage devices cannot flexibly adjust the tool retrieval angle according to the processing environment.

[0012] By exposing and fixing frequently used tools while storing infrequently used tools separately, it is easy to quickly find the tools during processing. Through the synergistic effect of the main storage compartment and the tool storage structure, the problem of mixed tools and inconvenient access in traditional storage devices is solved.

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] Please see Figures 1-5A tool storage device for CNC machine tools includes a first storage box 1, a second storage box 3 connected to the first storage box 1 via a rotating shaft fixing seat 2, a main storage rail 4 slidably connected inside the first storage box 1, an auxiliary handle 5 fixedly installed on the upper wall of the main storage rail 4, a plurality of sliding limiting grooves 6 opened on the front wall of the auxiliary handle 5, a plurality of storage slots 7 opened inside the main storage rail 4, a tool storage structure for storing tools slidably installed in one storage slot 7, the tool storage structure including a tool storage box 8 slidably connected to the storage slot 7, a support plate 9 fixedly installed on the front wall of the tool storage box 8, a guide rod 10 fixedly installed on the upper wall of the support plate 9, a limiting block 11 fixedly installed on the upper end face of the guide rod 10, a limiting pressure plate 12 slidably connected to the guide rod 10 below the limiting block 11, and a reset spring 13 fitted on the guide rod 10 to press the limiting pressure plate 12 against the limiting block 11.

[0017] Please see Figure 3 The first storage box 1 has a spring groove 14, an adjusting pressure plate 15 is slidably installed in the spring groove 14, a limiting plate 16 is fixedly installed on the upper wall of the adjusting pressure plate 15, and two spring limiting rods 17 are fixedly installed on the lower wall inside the spring groove 14. Supporting springs 18 are fitted on the two spring limiting rods 17 to push the adjusting pressure plate 15 against the upper wall inside the spring groove 14.

[0018] Please see Figure 3 When the support spring 18 pushes the adjusting plate 15 against the upper wall inside the spring groove 14, the limiting plate 16 extends out of the upper wall of the first storage box 1 from the spring groove 14. The length of the adjusting plate 15 is greater than that of the spring groove 14, and the distances at both ends extending out of the spring groove 14 are the same.

[0019] Please see Figure 3 The second storage box 3 has three slots 19 at its connecting end that can be connected to the limiting plate 16. A knife holder 20 is fixedly installed at the opening inside the second storage box 3. A buffer pad 21 is fixedly installed on the lower wall inside the second storage box 3.

[0020] Please see Figure 2 Two auxiliary limiting grooves 22 are provided on the wall of the opening end of the second storage box 3, and two magnetic suction grooves 23 are provided on the front wall of the first storage box 1. Two auxiliary limiting rods 24 are fixedly installed on the auxiliary handle 5 and respectively inserted into the two auxiliary limiting grooves 22. Magnetic blocks 25 that are attracted into the two magnetic suction grooves 23 are also fixedly installed on the auxiliary handle 5.

[0021] Please see Figure 6 The knife storage box 8 is equipped with a knife mold spring pad sponge 26. When in use, the knife mold spring pad sponge 26 has a groove customized according to the shape of the knife to prevent shaking.

[0022] Please see Figure 3An observation window 27 is fixedly installed on the upper wall of the first storage box 1. When in use, the position of the target tool can be confirmed through the observation window 27.

[0023] In Example 1, the target slot 19 of the second storage box 3 is aligned with the limiting plate 16. The adjusting pressure plate 15 is released, the support spring 18 is elastically reset, and the adjusting pressure plate 15 is pushed to drive the limiting plate 16 into the slot 19, thus fixing the angle of the second storage box 3. The knife-taking direction can be flexibly adjusted according to different spaces. When the slot 19 corresponds to 0°, the space occupied is minimal, making it easy to carry.

[0024] Specifically, the operator holds the auxiliary handle 5 and pulls the main storage compartment 4 out along the first storage box 1 (separating the two magnetic blocks 25 from the two magnetic slots 23) until the two auxiliary limiting rods 24 disengage from the two auxiliary limiting slots 22. The operator then presses both ends of the adjusting plate 15 (the length of the adjusting plate is greater than the spring slot 14, and the force on both ends is balanced), causing it to move downwards along the spring slot 14 and compress the support spring 18 on the spring limiting rod 17. At this time, the limiting plate 16 on the adjusting plate exits from the current slot 19 of the second storage box 3, releasing the angle lock. Then, with the rotating shaft fixing seat 2 as the axis, the second storage box 3 is rotated outwards. The appropriate angle is selected according to the operational needs (the three slots 19 correspond to three angles: 0°, 90°, and 180°). When the slot 19 corresponds to 0°, the space occupied is minimal, making it easy to carry. The limiting plate 16, in conjunction with the two auxiliary limiting rods 24, restricts the rotational freedom of the second storage box 3, improving the stability when carrying it. For example, 90° is selected in narrow spaces and 180° is selected in spacious areas to maximize the operating surface; finally, the angle is locked: align the target slot 19 of the second storage box 3 with the limiting plate 16, release the adjusting pressure plate 15, the support spring 18 elastically resets, push the adjusting pressure plate 15 to drive the limiting plate 16 into the slot 19, and the angle is fixed. At this time, the tool holder 20 and the buffer pad 21 (protecting the tool cutting edge) of the second storage box 3 are in a horizontal or tilted stable state, which facilitates the loading and unloading of tools.

[0025] Example 2: In this example, frequently used tools are exposed and fixed, while infrequently used tools are stored separately, making it easy to quickly find the tools during processing. Through the synergistic effect of the main storage compartment and the tool storage structure, the problem of mixed tools and inconvenient access in traditional storage devices is solved.

[0026] Specifically, when preparing tools before machining, follow the logic of "quickly retrieving frequently used tools and accurately selecting infrequently used tools": Accessing commonly used knives: Hold the auxiliary handle 5 and pull it outwards. The main storage compartment 4 slides along the first storage box 1, and the magnetic block 25 of the auxiliary handle disengages from the magnetic groove 23 until the main storage compartment 4 is fully exposed. At this point, commonly used knives can be directly taken out from the die-cutting spring pad 26 (with grooves customized according to the shape of the knives to prevent shaking) in the knife storage box 8 and inserted into the knife fixing bracket 20 of the second storage box 3 for quick access during processing.

[0027] Retrieving infrequently used tools: After confirming the position of the target tool through the observation window 27, there is no need to pull out the entire main storage compartment 4. Simply press down on the limiting plate 12 (compressing the return spring 13) along the guide rod 10 to disengage the plate from the sliding limiting groove 6 of the auxiliary handle 5, thus releasing the constraint on the tool storage box 8. Then, hold the support plate 9 and pull out the corresponding tool storage box 8 individually along the storage groove 7. After use, reverse the operation to reset. During this process, the magnetic block 25 remains attached to the magnetic groove 23 to ensure the stability of the main storage compartment 4. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
