[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] like Figures 1 to 4 The C-shaped fixed tool sleeve clamping device shown comprises: a fixing seat 10 and a clamping plate 20, wherein the fixing seat 10 is used to fix the clamping plate 20 to the tool disc 02, and the clamping plate 20 is used to form an elastic clamping effect on the tool sleeve 01, and comprises a mounting section 21 and a clamping section 22;

[0029] The mounting section 21 is located in the middle of the clamping plate 20, on the side of the fixed seat 10 perpendicular to the cutter disc 02, and the mounting section 21 is fixedly connected to the fixed seat 10. Both ends of the clamping plate 20 are bent toward the side away from the fixed seat 10 to form two clamping sections 22 respectively. The two clamping sections 22 are connected to the mounting section 21 to form a C-shaped clamping space 1. The tool sleeve 01 is arranged in the clamping space 1, and the mounting section 21 and the two clamping sections 22 are all arranged to fit the outer side surface of the tool sleeve 01.

[0030] The C-shaped fixed tool sleeve 01 clamping device of the utility model has a simple and compact structure. It can form an elastic clamping effect on the tool sleeve 01 only through the clamping plates 20 bent at both ends, reducing the difficulty of installation and maintenance; it is easy to assemble and replace; and the installation section 21 and the clamping section 22 form a three-dimensional contact effect on the outer side of the tool sleeve 01, providing a continuous and stable clamping force, and the clamping effect is good, thereby reducing the displacement or vibration of the tool during high-speed rotation or processing, ensuring processing accuracy and efficiency.

[0031] When the tool sleeve 01 is not clamped, the clamping section 22 has a tendency to tilt toward the inside of the clamping space 1, so that when the tool sleeve 01 enters the clamping space 1, it needs to overcome the force of the clamping sections 22 on both sides, thereby ensuring that after the tool sleeve 01 is assembled, the clamping sections 22 on both sides contact and abut the outer side of the tool sleeve 01, ensuring the stability of the connection and preventing deviation or shaking during the processing.

[0032] On the basis of the above embodiment, a transition section 23 is arranged between the clamping section 22 and the mounting section 21. The transition section 23 is an arc-shaped structure, and its two ends are fixedly connected to the clamping section 22 and the mounting section 21 respectively; the arc-shaped transition section 23 provides a smooth transition from the mounting section 21 to the clamping section 22, reduces stress concentration points, and helps to improve the structural strength and durability of the clamping device; at the same time, it can reduce the local stress caused by the vibration of the tool during high-speed rotation, thereby enhancing the clamping force of the tool sleeve 01 and improving the stability of the tool during the processing; in addition, it is also more smooth and beautiful visually.

[0033] On the basis of the above-mentioned embodiment, the length of the clamping section 22 is gradually reduced from one end facing the mounting section 21 to the end facing away from the mounting section 21; while ensuring a stable clamping effect, it avoids interference with the clamping plate 20 in the adjacent clamping device, helps to optimize the utilization of the clamping space 1, and ensures the stability of the clamping effect on the tool sleeve 01.

[0034] On the basis of the above embodiment, a clamping section 24 is further provided at one end of the clamping section 22 away from the mounting section 21. The clamping section 24 is inclined toward the inside of the clamping space 1, and the inner side surface of the clamping section 24 is arranged to fit the outer side surface of the tool sleeve 01; the inclined clamping section 24 provides additional clamping force to the outer side surface of the tool sleeve 01 after the tool sleeve 01 enters the clamping space 1, so that the tool sleeve 01 is more stable in the clamping space 1 and the displacement during high-speed rotation or processing is reduced; and the clamping section 24 forms a certain self-locking effect on the tool sleeve 01, and can maintain the stable position of the tool sleeve 01 when subjected to vibration or impact, thereby preventing the tool sleeve 01 from escaping from the clamping space 1.

[0035] On the basis of the above embodiment, a guide section 25 is further provided at one end of the clamping section 24 away from the clamping section 22. The guide section 25 is inclined toward the side away from the inside of the clamping space 1, and an opening 2 for the tool sleeve 01 to enter the inside of the clamping space 1 is formed between the guide sections 25 on both sides. The inclined guide sections 25 provide a smooth entry path for the tool sleeve 01 to enter the clamping space 1, so that the tool sleeve 01 can slide into the clamping space 1 more easily, simplifying the installation process of the tool sleeve 01; and reducing the friction between the tool sleeve 01 and the clamping device during the installation process, thereby reducing the risk of damage to the tool sleeve 01.

[0036] On the basis of the above-mentioned embodiment, the angle between the clamping section 24 and the guide section 25 is 130°~150°; this helps to more accurately position the tool sleeve 01 when entering the clamping space 1, reduces the positioning error caused by too large or too small an angle, and can provide a good self-locking effect. Even in the case of high-speed rotation or vibration, the clamping effect of the tool sleeve 01 can be kept stable, so that the clamping device can be suitable for tool sleeves 01 of different sizes and shapes.

[0037] Based on the above embodiment, the bending angle of the clamping section 22 relative to the mounting section 21 is 80°~90°, so that the clamping plate 20 forms a clamping effect close to a right angle on the tool sleeve 01, ensuring the stability of the tool during high-speed rotation or processing, while also facilitating the removal of the tool sleeve 01, ensuring that the clamping force applied to tool sleeves 01 of different sizes and shapes is within an appropriate range.

[0038] On the basis of the above embodiment, a first fixing hole 11 is provided on the fixing base 10, and a through mounting hole 21a is provided on the mounting section 21. Two first fixing holes 11 and two mounting holes 21a are provided, and the first fixing hole 11 and the mounting hole 21a are coaxially arranged. The fastener passes through the first fixing hole 11 and the mounting hole 21a in sequence to connect the fixing base 10 and the mounting section 21; through the coaxially arranged first fixing hole 11 and the mounting hole 21a, the fastener can ensure that the connection between the fixing base 10 and the mounting section 21 is more stable, and reduce errors or looseness caused by improper connection; the coaxially arranged first fixing hole 11 and the mounting hole 21a simplify the installation process, reduce the complexity of the alignment hole, help to improve the rigidity of the overall structure, and make the clamping device stronger when subjected to force.

[0039] On the basis of the above embodiment, a second fixing hole 12 is provided through the fixing seat 10, and the second fixing hole 12 is located on both sides of the fixing seat 10 parallel to the plane where the cutter disc 02 is located, and the axis is perpendicular to the axis of the first fixing hole 11. The fastener passes through the second fixing hole 12 to connect the fixing seat 10 and the cutter disc 02. The setting of the second fixing hole 12 allows the clamping device to be directly installed on the cutter disc 02 through the fixing seat 10, which simplifies the installation steps and facilitates installation and replacement. After the fixing seat 10 is installed, the fastener provides support for the clamping device, thereby enhancing the structural stability of the entire clamping device.

[0040] like Figure 5 As shown, the utility model also provides a disc track tool magazine, which is equipped with a plurality of C-shaped fixed tool sleeve 01 clamping devices as above, including a tool disc 02 and a driving mechanism 03, and the plurality of C-shaped fixed tool sleeve 01 clamping devices are arranged in sequence along the edge of the tool disc 02, and the driving mechanism 03 is connected to the tool disc 02 by a chain drive, which is used to drive the tool disc 02 to rotate; each C-shaped fixed tool sleeve 01 clamping device serves as an independent module, and can quickly select and replace tools according to processing requirements, adapt to different processing tasks, and ensure the stability and accuracy of the tool during the clamping and releasing process, realize automatic tool replacement, and improve processing efficiency, and the modular design of the clamping device facilitates individual maintenance and replacement, which helps to reduce maintenance costs and time.
