[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0031] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0032] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more. Furthermore, the terms "first" and "second" are used merely for descriptive distinction and have no specific meaning.

[0033] In one embodiment of this utility model, such as Figure 1-6As shown, a milling machine tool mounting structure is provided, including: a fixed base 1, a tool 2, a tool sleeve 3, and a positioning element 4. The fixed base 1 has a guide hole on its surface; the tool 2 is disposed on one side of the fixed base 1 and can pass through the guide hole; the tool sleeve 3 is disposed on the other side of the fixed base 1, and a slot for engaging the tool 2 is provided in the middle of the tool sleeve 3, allowing the tool sleeve 3 to rotatably tighten the tool 2; the positioning element 4 is movably connected to the fixed base 1 and the tool 2, and the positioning element 4 is used for the tool 2 to slide along the tightening direction of the tool sleeve 3.

[0034] The milling machine tool mounting structure provided by this utility model, by setting a tool sleeve 3 to mount the tool 2, not only avoids damage to the tool 2 itself or the connection parts of the machine tool, ensuring the accuracy of the tool 2 and the service life of the machine tool, but also buffers the impact force during loading and unloading, protecting the tool 2 and the machine tool. The tool sleeve 3 allows for rotatable tightening of the tool 2, improving the installation efficiency of the tool 2, significantly shortening the time required for each tool 2 installation, reducing downtime, and thus improving overall machining efficiency.

[0035] Preferably, the positioning element 4 can be composed of a pin.

[0036] Preferably, the tool holder 3 is cylindrical, comprising an upper cylindrical body 31 and a lower cylindrical body 32, with the inner diameter of the upper cylindrical body 31 being larger than the inner diameter of the lower cylindrical body 32. When a different type of tool 2 needs to be installed, the tool holder 3 can be reversed to accommodate tools 2 of different diameters, improving the versatility of the tool holder 3 and the entire milling machine tool 2 mounting structure, and reducing the cost of equipping multiple tool holders 3 to accommodate different tools 2.

[0037] The milling machine tool mounting structure also includes a buffer assembly 5, which is disposed on the fixed base 1 and is used to buffer the tool 2 from screwing in the direction of the tool sleeve 3.

[0038] Specifically, the buffer assembly 5 includes an upper seat 51, a lower seat 52, a sliding cylinder 53, a top plate 54, a clamping plate 55, and an elastic element 56. The upper seat 51 and the lower seat constitute a fixed seat 1, with a gap between them. A guide hole passes through the upper seat 51 and the lower seat. The cylinder hole of the sliding cylinder 53 is used for the tool 2 to pass through. The top plate 54 is located on the top of the sliding cylinder 53, and the clamping plate 55 is located in the middle of the sliding cylinder 53. The sliding cylinder 53 passes through the guide hole. The lower limit of the sliding cylinder 53 is clamped to the top of the upper seat 51 by the top plate 54, and the upper limit of the sliding cylinder 53 is clamped between the upper seat 51 and the lower seat by the clamping plate 55. The elastic element 56 is sleeved on the sliding cylinder 53, and the two ends of the elastic element 56 abut against the clamping plate 55 and the lower seat, respectively.

[0039] When the cutter 2 is not installed, the elastic element 56, relying on its own elastic potential energy, always exerts an upward supporting force on the sliding cylinder 53, steadily supporting the sliding cylinder 53 and maintaining its stability in the initial position. During the installation process of the cutter 2, the rotation of the cutter sleeve 3 causes the cutter 2 to gradually slide down along the guide hole. During this process, the cutter 2 will press against the top plate 54, thereby causing the sliding cylinder 53 to move downward against the elastic force of the elastic element 56.

[0040] Furthermore, during the installation of the tool 2, when the tool sleeve 3 rotates and tightens the tool 2, the tool 2 slides down along the guide hole, and the top plate 54 can accurately support the tool 2, providing a stable support point for the tool 2, ensuring that the tool 2 remains vertical and stable during the screwing process, and preventing the tool 2 from shifting due to uneven force, thereby ensuring the accuracy and stability of the tool 2 installation.

[0041] A retaining plate 55 is positioned in the middle of the sliding cylinder 53 and works in conjunction with the elastic element 56. The elastic element 56 is sleeved on the sliding cylinder 53, with its two ends abutting against the retaining plate 55 and the lower seat body, respectively. During the engagement of the tool 2, the elastic element 56 acts as a buffer. The retaining plate 55 effectively limits the upper limit of movement of the sliding cylinder 53. When the sliding cylinder 53 moves upward, the retaining plate 55 is locked between the upper seat body 51 and the lower seat body, preventing the elastic element 56 from being over-compressed. This measure greatly reduces the risk of damage to the elastic element 56 due to excessive force, extends the service life of the elastic element 56, ensures that the buffer assembly 5 can stably perform its buffering function for a long time, and thus improves the reliability and durability of the entire milling machine tool 2 mounting structure.

[0042] The milling machine tool mounting structure also includes a clamping assembly 6, which is located at the bottom of the tool holder 3 and is used to clamp the tool holder 3.

[0043] Specifically, the clamping assembly 6 includes a semi-clamping body 61 and a locking element 62. The semi-clamping body 61 is symmetrically arranged at the bottom of the tool holder 3. By clamping along the tool holder 3, it can firmly fix the tool holder 3, preventing it from shaking or shifting during the installation of the tool 2, and ensuring the accuracy and stability of the tool 2 installation. The locking element 62 is set on the semi-clamping body 61. The surface of the tool holder 3 has through holes 63 for engaging the locking element 62, further enhancing the fixing effect of the semi-clamping body 61 and the tool holder 3, making the tool holder 3 more stable in the clamped state, and preventing the tool holder 3 from accidentally rotating or loosening during the rotation and engagement of the tool 2 or during milling machine operation. The symmetrical semi-clamping body 61 can repeatedly clamp and disassemble along the tool holder 3, and the symmetrical semi-clamping body 61 can drive the tool holder 3 to rotate and engage the tool 2. When it is necessary to install or maintain the tool holder 3, the semi-clamp body 61 can be easily opened and the tool holder 3 can be disassembled, which facilitates the maintenance and upkeep of the equipment and extends its service life.

[0044] The milling machine tool mounting structure also includes a rotating component 7, which is located at the bottom of the tool holder 3. The rotating component 7 is used to drive the tool holder 3 to perform a rotating motion.

[0045] Specifically, the rotating assembly 7 includes a left and right movable source 71 and a rotating movable source 72. Both the left and right movable source 71 and the rotating movable source 72 can be made of cylinders. The left and right movable source 71 is used to clamp the tool sleeve 3, and the rotating movable source 72 is used to clamp the tool sleeve 3 and then rotate the tool sleeve 3 so that the tool 2 and the tool sleeve 3 can rotate together.

[0046] Preferably, the semi-clamp body 61 can be symmetrically arranged on the left and right drive ends of the left and right moving sources 71.

[0047] The milling machine tool mounting structure also includes an auxiliary component 8, which is disposed on the side of the tool 2. The auxiliary component 8 is used to assist the tool 2 in rotating.

[0048] Specifically, the auxiliary component 8 includes a mating tooth surface 81 and a mating tooth body 82. The mating tooth surface 81 is circumferentially distributed on the surface of the tool 2, and the mating tooth body 82 is rotatably disposed on the side of the tool 2. The mating tooth body 82 meshes with the mating tooth surface 81.

[0049] By providing a rotatable mating tooth 82 on the side of the tool 2, which meshes with the circumferentially distributed mating tooth surfaces 81 on the surface of the tool 2, additional assistance is provided for the rotation of the tool 2. During the rotation and engagement process of the tool sleeve 3 driving the tool 2, the mating tooth 82 and the mating tooth surfaces 81 work together to make the rotation of the tool 2 more stable and smooth, which helps to improve the engagement accuracy of the tool 2 during installation.

[0050] Preferably, during use, the position of the mating tooth 82 can be automatically fixed.

[0051] Moreover, the auxiliary component 8 plays a certain supporting and stabilizing role during the rotation of the tool 2, preventing the tool 2 from shaking or deviating due to uneven force, further ensuring the stability and reliability of the tool 2 during milling, thereby improving the machining quality.

[0052] The installation process of the tool 2 in this embodiment is as follows: First, drive the clamping sleeve 3, drive the left and right movable sources 71 so that the symmetrical semi-clamping bodies clamp the tool sleeve 3. The locking element 62 cooperates with the through hole 63 of the tool sleeve 3. Then, insert the tool 2 into the sliding cylinder 53 and insert the tool 2 to the top of the tool sleeve 3. Then, insert the positioning element 4 into the tool 2, the sliding cylinder 53 and the upper seat 51. Then, drive the rotating movable source 72 to rotate the tool sleeve 3 to screw the tool 2. The tool 2 presses the top plate 54 down until the tool 2 is tightened. Then, remove the positioning element 4 and rotate the rotating movable source 72 to drive the tool sleeve 3 and the tool 2 to rotate.

[0053] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes, and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
