DETAILED DESCRIPTION

[0017] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0018] like Figure 1-3 As shown, an embodiment of the utility model provides a quick assembly and disassembly mechanism of an ATC tool handle, comprising: a mounting seat 1 and a tool handle body 2; the mounting seat 1 is connected to an operating table.

[0019] An inserting plate 3, wherein the inserting plate 3 is fixedly mounted on the bottom of the mounting seat 1, and a slot is configured on the handle body 2;

[0020] A positioning component 4, wherein the positioning component 4 is mounted on the handle body 2, and when the inserting plate 3 is inserted into the slot, the handle body 2 is positioned and fixed by the positioning component 4;

[0021] The fixing assembly 5 comprises two fixing plates 51 symmetrically distributed and rotatably mounted on both sides of the mounting seat 1 . A driving motor 52 for driving the fixing plates 51 to rotate is mounted on the mounting seat 1 .

[0022] The handle body 2 interacts with the insert plate 3 on the mounting seat 1 through the slot thereon. When the handle needs to be installed or replaced, the handle body 2 is placed on the mounting seat 1 so that the insert plate 3 can be inserted into the slot of the handle body 2. At this time, the positioning component 4 begins to play a role. It is installed on the tool handle body 2 to ensure that the top of the tool handle body 2 can be accurately positioned and fixed in the appropriate position after being inserted into the slot. The tool handle body 2 is initially fixed. Then, the fixing component 5 intervenes to ensure the stability of the tool handle body 2. The fixing component 5 is composed of two symmetrically distributed fixing plates 51, which are rotatably installed on both sides of the mounting seat 1. The mounting seat 1 is equipped with a driving motor 52, which is used to drive the fixing plate 51 to rotate. When the driving motor 52 is started, it will rotate the fixing plate 51 inward or outward, thereby clamping or releasing the tool handle body 2. During the clamping process, the fixing plate 51 rotates to contact the tool handle body 2 and apply pressure to ensure that the tool handle body 2 will not loosen when rotating at high speed or subjected to cutting force. When the tool handle needs to be released or replaced, the driving motor 52 operates in reverse to make the fixing plate 51 loosen the tool handle body 2, allowing the tool handle to be removed from the mounting seat 1. Due to the participation of the driving motor 52, the whole process achieves rapid response and efficient operation, which significantly improves the tool change speed and processing efficiency. In addition, the design of the mechanism allows for quick installation and removal of the tool holder without sacrificing accuracy and stability, which is especially important for production lines that require frequent tool changes. By simplifying the operating process and reducing manual intervention, the mechanism not only improves production efficiency, but also reduces the risk of equipment damage or processing errors caused by improper human operation.

[0023] like Figure 2 As shown, in some embodiments, two mounting grooves are constructed on the mounting seat 1, and the positioning assembly 4 includes two positioning plates 41 respectively slidably installed in the two mounting grooves, a return spring 42 is fixedly installed between the positioning plate 41 and the inner wall of the mounting groove, one side of the positioning plate 41 is constructed as an arc surface, and a positioning groove is constructed on the handle body 2, and one end of the positioning plate 41 is inserted into the positioning groove.

[0024] When the handle body 2 needs to be installed on the mounting seat 1, the handle body 2 is first aligned with the plug plate 3 on the mounting seat 1, and then inserted along the slot of the handle body 2. Two positioning plates 41 are slidably installed in the two mounting grooves constructed on the mounting seat 1, and one side of each positioning plate 41 is designed as an arc surface, so that they can match the positioning groove on the handle body 2. One end of the positioning plate 41 is inserted into the positioning groove of the handle body 2. In order to ensure that the positioning plate 41 can be stably maintained in the appropriate position, a reset spring 42 is fixedly installed between each positioning plate 41 and the inner wall of the mounting groove. The function of these reset springs 42 is to provide the necessary elastic force for the positioning plate 41 when the handle body 2 is inserted or removed, so as to achieve fast and accurate positioning. When the handle body 2 is inserted into the slot and contacts the positioning plate 41, the positioning plate 41 is pushed by the handle body 2, overcomes the elastic force of the return spring 42, and moves into the installation slot, thereby allowing the handle body 2 to be further inserted. Once the handle body 2 is fully inserted, the arc surface of the positioning plate 41 is tightly matched with the positioning slot of the handle body 2. Through the elastic force of the return spring 42, the positioning plate 41 quickly returns to the initial position, realizing the precise positioning of the handle body 2. At this time, the fixing plate 51 in the fixing assembly 5 rotates under the drive of the driving motor 52, clamps the handle body 2, and completes the assembly and disassembly process. Due to the coordinated action of the positioning plate 41 and the return spring 42, the entire assembly and disassembly process realizes fast, accurate and reliable positioning and fixing of the handle, thereby improving the efficiency and stability of the automatic tool changing system.

[0028] A rotating motor 8 is fixedly installed on one side of the support frame 7. The rotating motor 8 is responsible for driving the rotation of the entire tool magazine 9. The output end of the tool magazine 9 is fixedly installed. The design of the tool magazine 9 allows the storage and selection of multiple tool handle bodies 2 to meet different processing requirements. The tool magazine 9 is composed of a circular plate 91 fixedly installed on one side of the rotating motor 8. A plurality of connecting plates 92 are distributed in a circular array on the outer circumference of the circular plate 91. A placement plate 93 is rotatably installed on each connecting plate 92 for placing the tool handle body 2. A torsion spring is provided at the connection between the connecting plate 92 and the placement plate 93, which provides the elastic force required for the placement plate 93 when rotating or positioning the tool handle body 2. A magnet is fixedly installed inside the placement plate 93, and the top of the tool handle body 2 is attracted by magnetic force to ensure the stable positioning of the tool handle body 2 in the tool magazine 9. This magnetic attraction method not only improves the assembly and disassembly speed of the tool handle body 2, but also simplifies the mechanical structure and reduces physical contact and wear.
