[0014] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0015] 1. In the utility model, when the tool mounting seat in the external CNC lathe takes the tool in the tool library, the motor drives the tool disc and multiple tool holders to rotate with a connecting plate, and then the camera records and uploads the tool movement position. When the required tool moves to a position parallel to the guide support shell, the external control system shuts down the motor, then starts the cylinder, and then the push rod pushes the tool to be used into the guide support shell, and then stands upright along the inner wall of the guide support shell. At this time, the tool is taken away by the tool mounting seat, and each tool is well protected without affecting the tool changing operation, thereby ensuring that the tool changing operation can be carried out smoothly.

[0016] 2. In the utility model, when returning a used tool, the tool mounting seat returns the tool to the guide support shell, and then the tool slides down along the guide support shell and is laid flat, and then the movable end of the cylinder is controlled to retract, and then the push rod uses a connecting rod to pull the pressure rod to move, and the pressure rod squeezes the tool in the guide support shell, so that the tool is reinserted into the tool holder, and the used tool can return to a relatively closed space, effectively preventing the tool from being attached to dust.

[0039] Combination Figure 3 As shown, in the above embodiment, a rubber pad 400 is installed inside the tool magazine 110, and a plurality of tool holders 130 are all located in front of the rubber pad 400. The rubber pad 400 can prevent the tools from being worn by the inner wall of the tool magazine 110.

[0040] The working principle and use process of the utility model: when the device is put into actual use, multiple tool holders 130 are placed with tools of different models, and then the electrical components in the device are connected to the control system of the external CNC lathe. This operation is completed by a technician in the field. Then, when the tool mounting seat in the external CNC lathe approaches and the tool is taken, the motor 150 uses the connecting plate 160 to control the tool disc 120 and multiple tool holders 130 to rotate, and then the camera 190 records and uploads the tool movement position. When the taken tool moves to a position parallel to the guide support shell 220, the external control system shuts down the motor 150 and then starts the cylinder 170, then the push rod 180 pushes the tool to be used into the guide support shell 220, and then stands upright along the inner wall of the guide support shell 220. At this time, the tool is taken away by the tool mounting seat, and each tool is well protected without affecting the tool changing operation, so that the tool changing operation can be carried out smoothly. Then, when returning the used tool, the tool mounting seat returns the tool to the guide support shell 220, and then the tool slides down along the guide support shell 220 and is laid flat. Then the movable end of the control cylinder 170 is retracted, and then the push rod 180 uses the connecting rod 240 to pull the pressure rod 230 to move, and the pressure rod 230 squeezes the tool in the guide support shell 220, so that the tool is reinserted into the tool holder 130.

[0041] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
