Description

Technical Field

[0001] This utility model relates to the field of cutting tool management technology for industrial processing equipment, and in particular to a cutting tool replacement holder for quick replacement of dual cutting tools. Background Technology

[0002] A tool changer is an auxiliary tool used in industrial processing equipment (such as waterjet cutting machines, laser cutting machines, CNC machine tools, etc.). It is mainly used to store, fix and manage tool heads, and to enable quick replacement of tool heads when needed.

[0003] However, existing tool replacement racks mostly adopt open or simple layered structures. Tool heads are usually directly stacked or randomly inserted into the rack, lacking clear positioning and fixing mechanisms. This storage method makes it difficult to distinguish tool heads of different models, sizes or functions, increasing the risk of misuse. Direct contact between tool heads or between tool heads and the rack can easily cause blade wear or structural deformation due to collisions.

[0004] For example, when storing multiple cutting heads in the traditional way, the cutting heads are randomly inserted into the frame, and the cutting edge is in direct contact with the frame or other cutting heads. During handling or daily operation, the cutting edge may chip or the cutting head may be bent due to vibration or collision, which may lead to a decrease in the accuracy of the cutting head, burrs or dimensional deviations on the cutting edge, and frequent calibration or replacement of the cutting head, increasing maintenance costs. Utility Model Content

[0005] This utility model discloses a tool head replacement holder for quick replacement of dual tool heads, aiming to solve the technical problems of existing tool head replacement holders that mostly adopt open or simple layered structures, where tool heads are usually directly stacked or randomly inserted into the holder without clear positioning and fixing mechanisms. This storage method makes it difficult to distinguish tool heads of different models, sizes or functions, increasing the risk of misuse. Direct contact between tool heads or between tool heads and the holder can easily cause wear of the cutting edge or structural deformation due to collision.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A blade replacement holder for quick replacement of dual blades includes a support base with a mounting box on the top outer wall of the support base. It also includes: a storage mechanism slidably connected to the interior of the mounting box; and a limiting mechanism located on the storage mechanism. The limiting mechanism includes six mounting brackets, each mounting bracket having three blade bodies. The bottom outer wall of each mounting bracket has three equidistant positioning grooves. The inner wall of each positioning groove has a mounting groove, a limiting groove, a return spring, and four fixing cylinders. A limiting rod is slidably connected to the inner wall of each fixing cylinder. One end of each limiting rod is fixedly connected to a limiting plate, and one end of each return spring is fixedly connected to the limiting plate. The blade body is engaged within the limiting groove.

[0008] The above technical solution enables rapid recycling of old cutter heads and replacement with new ones, achieving self-locking and fixing of the cutter heads to prevent them from loosening, falling off, or colliding with each other, thus preventing edge wear or structural deformation. Specifically, in use, the device is first installed on one side of the cutting equipment. When one cutter head needs to be replaced, the worker removes the old cutter head from the cutting equipment and, according to its classification position, inserts the top of the old cutter head upwards along one of the mounting slots, thus extending into the positioning slot. The top of the cutter head first contacts the limiting plate, pushing the limiting rod to slide towards the inner wall of the fixing cylinder. At the same time, the limiting plate moves upwards to compress the return spring. After the old cutter head is fully inside the positioning slot, the cutter head is rotated 90 degrees clockwise. Under the elastic force of the return spring, the limiting plate rebounds, driving the limiting rod to move the limiting plate in the opposite direction, so that the limiting plate and the top of the old cutter head fit tightly together, thus achieving the old cutter head being snapped and fixed in the limiting slot.

[0009] In a preferred embodiment, the positioning groove has a "T" shaped cross-section, and the opening of the positioning groove faces the bottom outer wall of the mounting bracket.

[0010] In this solution, since the cross-section of the positioning groove is "T"-shaped and the opening faces downward, the blade body is laterally limited by the "T"-shaped structure after insertion. Even if there is slight vibration or tilting during the sliding process of the storage mechanism, the blade body will not come out of the positioning groove, ensuring the safety and stability of the replacement process.

[0011] In a preferred embodiment, the storage mechanism includes four connecting plates, with a fixing plate between two adjacent connecting plates. The top and bottom outer walls of the mounting box each have two fixing grooves. The top outer walls of two of the connecting plates and the bottom outer walls of the other two connecting plates each have sliders, which are slidably connected to the inner walls of the fixing grooves.

[0012] In this design, when the operator pushes the slider to move linearly along the inner wall of the fixed groove using external force, the connecting plate and the fixed plate move synchronously within the fixed groove, thereby allowing the entire storage mechanism to be pulled out or pushed back into the mounting box. When the entire storage mechanism slides out to one end of the fixed groove, the operator pulls the mounting plate to move linearly along the slide. At this time, the protrusion slides synchronously within the slide. Then, the operator can manually apply lateral force to make the mounting plate rotate around the pivot, allowing the mounting plate to rotate around the pivot axis at a certain angle (0 to 90°). This design allows the mounting plate to dynamically adjust its tilt angle according to operational needs during the sliding process, making it easier for the operator to remove the cutter head body. The sliding-hinged composite structure allows the mounting plate to move in multiple directions within a limited space, avoiding the problem of traditional fixed mounting plates requiring a large operating space and saving internal space in the equipment.

[0013] As described above, a blade replacement holder for quick replacement of dual blades includes a support base with a mounting box on the top outer wall of the support base. It also includes: a storage mechanism slidably connected to the interior of the mounting box; and a limiting mechanism located on the storage mechanism. The limiting mechanism includes six mounting brackets, each with three blade bodies. The bottom outer wall of each mounting bracket has three equidistant positioning slots. The inner wall of each positioning slot has a mounting slot, a limiting slot, a return spring, and four fixing cylinders. A limiting rod is slidably connected to the inner wall of each fixing cylinder. One end of the limiting rod is fixedly connected to a limiting plate, and one end of the return spring is fixedly connected to the limiting plate. The blade body is engaged within the limiting slot. This utility model provides a blade replacement holder for quick replacement of dual blades, enabling rapid retrieval of old blade bodies and replacement with new blade bodies. It achieves self-locking of the blade bodies, preventing loosening, detachment, or collision of the blade bodies, thereby preventing edge wear or structural deformation. Attached Figure Description

[0019] The technical solutions of 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. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The present invention discloses a tool replacement holder for quick replacement of dual tool heads. It is mainly applicable to existing tool replacement holders that mostly adopt an open or simple layered structure. Tool heads are usually directly stacked or randomly inserted into the holder, lacking a clear positioning and fixing mechanism. This storage method makes it difficult to distinguish tool heads of different models, sizes or functions, increasing the risk of misuse. Direct contact between tool heads or between tool heads and the holder can easily lead to blade wear or structural deformation due to collision.

[0021] Reference Figure 1 and Figure 4 A blade replacement holder for quick replacement of dual blades includes a support base 1, with a mounting box 2 on the top outer wall of the support base 1. It also includes: a storage mechanism slidably connected to the interior of the mounting box 2; and a limiting mechanism located on the storage mechanism. The limiting mechanism includes six mounting brackets 6, each mounting bracket 6 having three blade bodies 8. The bottom outer wall of each mounting bracket 6 has three equidistant positioning grooves 11. The inner wall of each positioning groove 11 has a mounting groove 12, a limiting groove 13, a return spring 14, and four fixing cylinders 16. A limiting rod 17 is slidably connected to the inner wall of each fixing cylinder 16. One end of the limiting rod 17 is fixedly connected to a limiting plate 15. One end of the return spring 14 is fixedly connected to the limiting plate 15. The blade body 8 is engaged inside the limiting groove 13.

[0022] The positioning groove 11 has a "T" shaped cross-section, and the opening of the positioning groove 11 faces the bottom outer wall of the mounting bracket 6. Since the positioning groove 11 has a "T" shaped cross-section and the opening faces downward, the blade body 8 is laterally limited by the "T" shaped structure after insertion. Even if the storage mechanism experiences slight vibration or tilting during sliding, the blade body 8 will not come out of the positioning groove 11, ensuring the safety and stability of the replacement process.

[0023] In practical use, the cutter heads 8 on two adjacent mounting racks 6 are arranged in an alternating pattern. Three equally spaced numbered plates 7 are set on one outer wall of the mounting rack 6, and the numbered plates 7 correspond to the positions of the cutter heads 8. This dual identification design of "numbering + spatial misalignment" allows operators to quickly locate the target cutter head 8 without having to check each cutter head 8 one by one. They only need to use the number of the target cutter head 8 and the height or position of the mounting rack 6 to locate it. For example, when it is necessary to switch to a specific specification cutter head 8, the storage mechanism can be slid directly to the corresponding mounting rack 6, and the position of the target cutter head 8 can be quickly identified by the numbered plate 7, reducing search time and significantly improving operating efficiency. The staggered arrangement of the cutter heads 8 disperses within the limited space of the mounting rack 6, avoiding the problem of the cutter heads 8 obstructing each other (such as when adjacent cutter heads 8 are close together) that may be caused by the traditional parallel arrangement, making it difficult to observe the appearance of the cutter heads 8. The outer wall of each cutter head 8 can be clearly exposed, which is convenient for operators to inspect intuitively.

[0024] The depth of the limiting groove 13 is less than the depth of the mounting groove 12.

[0025] Specifically, in use, the device is first installed on one side of the cutting equipment. When it is necessary to replace one of the cutter heads 8, the operator removes the old cutter head 8 from the cutting equipment. Then, according to the classification position, the top of the old cutter head 8 is inserted upward along one of the mounting slots 12, thus extending into the interior of the positioning slot 11. The top of the cutter head 8 first contacts the limiting plate 15, pushing the limiting rod 17 to slide towards the inner wall of the fixing cylinder 16. At the same time, the limiting plate 15 moves upward to compress the return spring 14. When the old cutter head 8... After the cutter head body 8 is fully inserted into the positioning groove 11, rotate the cutter head body 8 clockwise by 90 degrees. Under the elastic force of the return spring 14, the limiting plate 15 rebounds, driving the limiting rod 17 to move the limiting plate 15 in the opposite direction, so that the limiting plate 15 is tightly fitted with the top of the old cutter head body 8, thereby realizing the old cutter head body 8 being snapped and fixed in the limiting groove 13. In this way, the staff can quickly retrieve the old cutter head body 8 and replace it with a new cutter head body 8. This structure uses the elastic force of the spring to achieve the self-locking fixation of the cutter head body 8, preventing the cutter head body 8 from loosening or falling off.

[0026] Reference Figure 1 and Figure 2 In a preferred embodiment, the storage mechanism includes four connecting plates 3, with a fixing plate 10 between two adjacent connecting plates 3. The top and bottom outer walls of the mounting box 2 are each provided with two fixing grooves. The top outer walls of two connecting plates 3 and the bottom outer walls of the other two connecting plates 3 are each provided with sliders 4, which are slidably connected to the inner wall of the fixing groove.

[0027] In the specific implementation process, the bottom outer wall of two of the connecting plates 3 and the top outer wall of the other two connecting plates 3 are provided with grooves 9. The inner wall of the grooves 9 is slidably connected with protrusions, and the mounting plates 5 are hinged between two adjacent protrusions through a pivot.

[0028] Specifically, when the operator pushes the slider 4 to move linearly along the inner wall of the fixed groove by external force, the connecting plate 3 and the fixed plate 10 will move synchronously within the fixed groove, thereby enabling the storage mechanism to be pulled out or pushed back into the mounting box 2. When the storage mechanism slides out to one end of the fixed groove, the operator pulls the mounting plate 5 to move linearly along the slide 9. At this time, the protrusion slides synchronously within the slide 9. Then, the operator can manually apply lateral force to make the mounting plate 5 rotate around the axis, so that the mounting plate 5 can rotate around the axis of rotation at a certain angle (0 to 90°). This design allows the mounting plate 5 to dynamically adjust the tilt angle according to the operation requirements during the sliding process, which makes it easier for the operator to remove the cutter head body 8. The sliding-hinged composite structure allows the mounting plate 5 to move in multiple directions within a limited space, avoiding the problem of the traditional fixed mounting plate 5 requiring an additional large operating space, thus saving the internal space of the equipment.

[0029] Reference Figure 1 and Figure 3 In a preferred embodiment, the three mounting brackets 6 are all located on one outer wall of the same mounting plate 5, and the three mounting brackets 6 are arranged vertically. The width of the three mounting brackets 6 decreases from top to bottom. This stepped layout forms a natural visual guide. The operator does not need to remember the position of the cutter head body 8. He / She can quickly locate it by simply determining whether the target cutter head body 8 is located on the upper, middle or lower layer of the mounting bracket 6. At the same time, it reduces the operation obstruction problem caused by the difference in the width of the mounting brackets 6 (the lower mounting bracket 6 will not obstruct the upper cutter head body 8 due to its excessive width).

[0030] Working principle: In use, the device is first installed on one side of the cutting equipment. When it is necessary to replace one of the cutter heads 8, the operator removes the old cutter head 8 from the cutting equipment. Then, according to the classification position, the top of the old cutter head 8 is inserted upward along one of the mounting slots 12, thus extending into the interior of the positioning slot 11. The top of the cutter head 8 first contacts the limiting plate 15, pushing the limiting rod 17 to slide towards the inner wall of the fixing cylinder 16. At the same time, the limiting plate 15 moves upward to compress the return spring 14. When the old cutter head 8 is fully inserted... After entering the positioning groove 11, rotate the cutter head body 8 clockwise by 90 degrees. Under the elastic force of the return spring 14, the limiting plate 15 rebounds, driving the limiting rod 17 to move the limiting plate 15 in the opposite direction, so that the limiting plate 15 fits tightly with the top of the old cutter head body 8, thereby achieving the old cutter head body 8 being snapped and fixed in the limiting groove 13. In this way, the staff can quickly recycle the old cutter head body 8 and replace it with a new cutter head body 8. This design can achieve the self-locking fixation of the cutter head body 8, preventing the cutter head body 8 from loosening or falling off, thereby preventing the cutting edge from wearing or the structure from deforming.

[0031] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
