DETAILED DESCRIPTION

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by technicians in the technical field of this application; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a tool holder assembly that is convenient for replacing a tool head, such as Figure 1-4 As shown, it includes a support seat 1; an adjustment mechanism arranged above the support seat 1; and a support mechanism arranged outside the adjustment mechanism; wherein the support mechanism includes: an assembly seat 2; a group of mounting blocks 3 symmetrically arranged on the inner side of the assembly seat 2; an extrusion protrusion 4 arranged on the inner sides of two of the mounting blocks 3, and a fastening cavity for fastening to a cutter head 17 is formed between the two extrusion protrusions 4; a fastener 18 arranged on the inner sides of the two extrusion protrusions 4; a reserved knife groove 5 is opened through the bottom side of the assembly seat 2; the same cutter head 17 is arranged in the fastening cavity and the reserved knife groove 5; and a limit plate 6 is arranged on the top of the cutter head 17.

[0023] It should be noted that since the traditional tool replacement method not only prolongs the replacement time and increases the risk of production interruption, but may also have a negative impact on the processing accuracy, the present solution significantly shortens the time required to replace the cutter head 17 and improves the working stability and accuracy after the replacement. The user only needs to perform simple operations to easily complete the replacement of the cutter head 17 without the need to use complex tools, thereby greatly reducing production interruptions and improving overall production efficiency. At the same time, the cutter head 17 can be clamped tightly and stably after replacement, reducing impact and vibration, ensuring processing stability and accuracy, and allowing the tool to be put into production directly after replacement without tedious debugging, further improving work efficiency. This design effectively combines convenience and efficiency, bringing significant benefits to production and processing.

[0024] Specifically, in this embodiment, the scheme mainly includes a support seat 1; the support seat 1 serves as the cornerstone of the entire tool holder assembly and provides a solid and stable support for the assembly; the adjustment mechanism located on the support seat 1 is responsible for fine-tuning the precise position and angle of the cutter head 17 to ensure that the cutter head 17 can be accurately and quickly restored to the predetermined working position after each replacement; a group of mounting blocks 3 and extrusion protrusions 4 carefully arranged on the inner side of the assembly seat 2 cooperate to form a compact and efficient fastening cavity specifically used to fix the cutter head 17; when the cutter head 17 is correctly placed in the fastening cavity, the two extrusion protrusions 4 will cooperate to apply pressure to the inside through the fastener 18, thereby tightly clamping the cutter head 17 to ensure that it will not loosen or shift during use;

[0025] In addition, the reserved tool groove 5 specially opened at the bottom of the assembly seat 2 allows a part of the cutter head 17 to be exposed, which is convenient for various cutting operations. It also minimizes the use of materials while ensuring the structural strength, thus achieving a lightweight design; the limit plate 6 on the top of the cutter head 17 ensures that the cutter head 17 will not be displaced unnecessarily due to vibration or external force during operation, thereby greatly improving the stability and accuracy of the operation;

[0026] When the cutter head 17 needs to be replaced, the operation process is also simple and efficient; the user only needs to loosen the fastener 18 to allow the extrusion protrusion 4 to release the clamping force on the cutter head 17, and then easily remove the old cutter head 17 from the reserved cutter groove 5; then, put the new cutter head 17 into the fastening cavity, and re-operate the fastener 18 to clamp it; the entire process does not require the use of complex tools, which greatly saves replacement time and improves work efficiency.

[0027] In a further preferred embodiment of the present invention, Figure 2 As shown, the two extrusion protrusions 4 are provided with first threaded holes 7 , and the two limiting plates 6 are provided with corresponding second threaded holes 8 . The first threaded holes 7 and the second threaded holes 8 are internally threadedly matched with the same fastening rod 9 .

[0028] In this embodiment, when the cutter head 17 needs to be fixed, the cutter head 17 is first placed in the fastening cavity to ensure that the top of the cutter head 17 is in contact with the limit plate 6. Then, the fastening rod 9 is rotated to make it tightly fit with the first threaded hole 7 in the two extrusion protrusions 4 and the second threaded hole 8 in the two limit plates 6. Due to the action of the thread, the fastening rod 9 will gradually push the extrusion protrusions 4 inward to clamp the cutter head 17. At the same time, the limit plate 6 will also more firmly limit the position of the cutter head 17 due to the action of the fastening rod 9.

[0029] In a further preferred embodiment of the present invention, Figure 4 As shown, the fastener 18 includes: a plurality of extrusion springs 10 arranged on the inner side of the extrusion protrusion 4; a damper arranged in the plurality of extrusion springs 10; and a compression pad 11 is arranged on the side of the plurality of extrusion springs 10 away from the extrusion protrusion 4, and the compression pad 11 is flexibly arranged.

[0030] In this embodiment, when the cutter head 17 is placed in the fastening cavity and is ready to be fastened by the fastener 18, the extrusion spring 10 will be compressed by the pressure from the cutter head 17. This compression process provides an initial, elastic buffer for the cutter head 17, reducing the impact and vibration caused by direct hard contact. When the spring is compressed or released, the damper will absorb part of the energy and reduce the oscillation of the spring, thereby ensuring the stability of the cutter head 17 during the fastening process. The extrusion pad 11 is arranged on the other side of the extrusion spring 10 and is in direct contact with the cutter head 17. Since the extrusion pad 11 is flexible, it can better adapt to the shape and surface of the cutter head 17, further reducing the wear and impact caused by hard contact.

[0031] In a further preferred embodiment of the present invention, Figure 2 As shown, the adjustment mechanism includes: a connecting frame 12 rotatably arranged above the support seat 1; a screw rod 13 rotating in the connecting frame 12; a first motor 14 arranged at the top of the connecting frame 12, and the output end of the first motor 14 is fixedly connected with the end key of the screw rod 13; a connecting block 15 is threadedly fitted on the screw rod 13, and the connecting block 15 is slidably fitted with the connecting frame 12; the connecting block 15 is fixedly connected to the assembly seat 2 on the side away from the connecting frame 12.

[0032] In this embodiment, by controlling the rotation of the connecting frame 12, the angle of the entire support mechanism and the cutter head 17 mounted thereon can be conveniently adjusted to meet different processing requirements. At the same time, the first motor 14 serves as a power source to drive the screw rod 13 to rotate. Since the connecting block 15 and the connecting frame 12 are slidably matched, the rotation of the screw rod 13 causes the connecting block 15 to move up and down in the connecting frame 12. This design ensures that the connecting block 15 can move stably and accurately, and drives the assembly seat 2 to adjust its height.

[0033] Through this height adjustment mechanism, the distance between the tool head 17 and the workpiece can be precisely controlled to adapt to different processing scenarios and workpiece requirements.

[0034] In a further preferred embodiment of the present invention, Figure 2-3 As shown, a second motor 16 is disposed on the bottom side of the support base 1 , and an output end of the second motor 16 is fixedly connected to an end key of the connecting frame 12 .

[0035] In this embodiment, by precisely controlling the rotation angle and speed of the second motor 16, the angle of the cutter head 17 can be precisely adjusted. This precise control not only helps to improve the processing quality, but also reduces processing errors and workpiece damage caused by improper angles.

[0036] In a further preferred embodiment of the present invention, Figure 2 As shown, a guiding cambered surface is arranged on the inner side of the reserved knife groove 5 .

[0037] In this embodiment, the guiding arc surface may be provided to better guide the motion trajectory of the tool during the machining process, to ensure that the tool can accurately enter and exit the tool groove, and to avoid deviation or damage to the tool during the machining process.

[0038] Working principle: When the device is used, the second motor 16 drives the connecting frame 12 to rotate, so that the entire support mechanism and the cutter head 17 mounted thereon can flexibly adjust the angle to meet various processing requirements; at the same time, the first motor 14 drives the screw rod 13 to rotate to achieve the height adjustment of the connecting block 15, which can accurately control the distance between the cutter head 17 and the workpiece, so as to adapt to different processing scenarios and workpiece requirements; the adjustment mechanism is responsible for fine-tuning the precise position and angle of the cutter head 17 to ensure that each time the cutter head 17 is replaced, it can accurately and quickly return to the predetermined working position;

[0039] A group of mounting blocks 3 and extrusion protrusions 4 on the inner side of the assembly seat 2 together form a compact and efficient fastening cavity, which is specifically used to fix the cutter head 17; when the cutter head 17 is correctly placed in the fastening cavity, the extrusion spring 10 will be compressed by the pressure from the cutter head 17; this compression process not only provides an initial, elastic buffer for the cutter head 17, reducing the impact and vibration caused by direct hard contact, but also ensures the stability of the cutter head 17 during the fastening process; at the same time, the setting of the damper can absorb part of the energy, reduce the oscillation of the spring, and further improve the stability and reliability of the entire system; in addition, the extrusion pad 11 is arranged on the other side of the extrusion spring 10, and is in direct contact with the cutter head 17; because the extrusion pad 11 is flexible, it can better adapt to the shape and surface of the cutter head 17, further reducing the wear and impact caused by hard contact; thereby tightly clamping the cutter head 17 to prevent it from loosening or shifting during use;

[0040] In addition, the reserved tool groove 5 specially provided at the bottom of the assembly seat 2 allows a portion of the tool head 17 to be exposed, which is convenient for various cutting operations; and the guide arc surface provided on the inner side of the reserved tool groove 5 better guides the movement trajectory of the tool during the processing, ensuring that the tool can accurately enter and exit the tool groove, and avoiding deviation or damage of the tool during the processing;

[0041] The limit plate 6 disposed on the top of the cutter head 17 ensures that the cutter head 17 will not be displaced unnecessarily due to vibration or external force during operation, thereby greatly improving the stability and accuracy of the operation;

[0042] When the cutter head 17 needs to be replaced, the operation process is also simple and efficient; the user only needs to loosen the fastener 18 to allow the extrusion protrusion 4 to release the clamping force on the cutter head 17, and then easily remove the old cutter head 17 from the reserved cutter groove 5; then, put the new cutter head 17 into the fastening cavity, and re-operate the fastener 18 to clamp it; the entire process does not require the use of complex tools, which greatly saves replacement time and improves work efficiency.
