[0021] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0022] like Figures 1 to 4 As shown, the embodiment of the present invention proposes a tool retrieval device structure for a CNC machine tool magazine, including a tool shifting seat 1, a circular groove is provided on the tool shifting seat 1, and the side wall of the circular groove cooperates with the tool handle. The inner side of the tool shifting seat 1 is provided with a clamping component 2 at the circular through groove, and the clamping component 2 is used to clamp the tool handle. The clamping component 2 includes an inner core sleeve 21, and the inner core sleeve 21 is located in the circular through groove on the tool shifting seat 1. The inner core sleeve 21 is fixedly connected to the tool shifting seat 1, and three through holes are provided on the outer side of the inner core sleeve 21. Steel balls 22 are placed at the through holes on the inner side of the inner core sleeve 21, and the diameter of the steel balls 22 is larger than the diameter of the through holes. An inner core shaft 23 is slidingly provided inside the inner core sleeve 21, and one end of the inner core shaft 23 is tapered. A tapered surface is provided on the inner side of the inner core sleeve 21 at the position of the through hole, and the tapered surface is in contact with the inner core shaft 23. In cooperation, the inner core shaft 23 is used to resist the steel ball 22. When in use, the tool shifter 1 is extended into the tool magazine so that the circular groove on the tool shifter 1 is aligned with the tool handle of the tool in the tool magazine, and then the tool handle is inserted into the circular groove on the tool shifter 1. The diameter of the steel ball 22 is larger than the through hole, and part of the sphere of the steel ball 22 passes through the through hole. When the tool handle enters, the tool handle contacts the steel ball 22, and the steel ball 22 retracts into the inner core sleeve 21. The inner core shaft 23 slides with the steel ball 22 to avoid the tool handle. After the tool handle enters the tool shifter 1, it fits with the inner wall of the circular groove of the tool shifter 1, and the inner core shaft 23 and the steel ball 22 move in opposite directions to reset. The steel ball 22 returns to the through hole, and the inner core shaft 23 resists the steel ball 22, and the steel ball 22 clamps the groove on the inside of the tool handle, thereby fixing the tool handle to achieve tool clamping. Then the tool shifter 1 moves backward to realize the process of taking the tool from the tool magazine. It is easy to use and has a simple structure.

[0023] like Figure 2 and Figure 4As shown, the inner side of the inner core sleeve 21 is slidably connected to the inner core adjustment shaft 3, and a circular groove is provided on the inner core shaft 23 and the inner core adjustment shaft 3 on the opposite side. A spring 4 is provided between the inner core shaft 23 and the inner core adjustment shaft 3, and the two ends of the spring 4 are respectively located in the circular grooves on the inner core shaft 23 and the inner core adjustment shaft 3. An adjustment piece 5 is provided between the tool shift seat 1 and the inner core sleeve 21. When the tool handle enters the circular groove of the tool shift seat 1, the tool handle pushes the steel ball 22 and the inner core shaft 23 to slide to avoid the tool handle. When the tool handle completely enters the circular groove on the tool shift seat 1, the outer side of the tool handle and the inner side of the circular groove are aligned. After the fit, the steel ball 22 and the inner core shaft 23 are reset under the push of the spring 4, and the steel ball 22 passes the through hole and is stuck in the groove on the inner side of the knife handle, and then the inner core adjustment shaft 3 slides in the inner core sleeve 21, close to the inner core shaft 23, squeezing the spring 4, and controlling the locking force of the spring 4 to be about 10000N. The spring 4 accumulates force and pushes the inner core shaft 23 through the spring 4, making the inner core shaft 23 and the steel ball 22 more stable, and at the same time making the steel ball 22 able to keep the knife handle stuck, making the steel ball 22 fix the tool more firmly and preventing the tool from shaking.

[0024] like Figure 1 and Figure 3 As shown, circular through holes are provided on the inner core shaft 23 and the inner core adjustment shaft 3. An air pipe 6 is fixedly connected to the inner core sleeve 21. The air pipe 6 is communicated with the interior of the inner core shaft 23. A quick-connect plug 7 is provided on the air pipe 6. A proximity switch 8 is installed on the tool shifting seat 1. The proximity switch 8 is used to detect the tool in the tool shifting seat 1. The air blowing device is connected through the quick-connect plug 7. During the tool removal process, air is ventilated through the air pipe 6 and the air enters the inner core sleeve 21. The tool is purged and cleaned through the inner core shaft 23 and the inner core adjustment shaft 3. The proximity switch 8 is used to detect whether there is a tool in the tool shifting seat 1.

[0025] Working principle: the tool shifter 1 is extended into the tool magazine so that the circular groove on the tool shifter 1 is aligned with the tool handle of the tool in the tool magazine, and then the tool handle is inserted into the circular groove on the tool shifter 1. The diameter of the steel ball 22 is larger than the through hole, and part of the sphere of the steel ball 22 passes through the through hole. When the tool handle enters, the tool handle contacts the steel ball 22, and the steel ball 22 retracts into the inner core sleeve 21. After the tool handle enters the tool shifter 1, it fits with the inner wall of the circular groove of the tool shifter 1. The steel ball 22 and the inner core shaft 23 are reset under the push of the spring 4. The steel ball 22 passes through the through hole and is stuck in the groove on the inside of the tool handle, and then the inner core adjustment shaft 3 slides in the inner core sleeve 21, approaches the inner core shaft 23, squeezes the spring 4, and controls the locking force of the spring 4 to be about 10000N. The spring 4 stores force and pushes the inner core shaft 23 through the spring 4, making the inner core shaft 23 and the steel ball 22 more stable.
