A plurality of first tool positioning key slots 5 are provided at the upper end of the tool holder plate 2, and a plurality of second tool positioning key slots 6 are provided on one side of the plurality of first tool positioning key slots 5. A clamping mechanism is provided on one side of the first tool positioning key slot 5. A proximity switch 8 is provided between two adjacent first tool positioning key slots 5, and each proximity switch 8 is respectively opposite to a second tool positioning key slot 6. A blowing mechanism is provided on the other side of the first tool positioning key slot 5. Two driving members 4 are provided at the upper end of the tool holder 1, and the two ends of the protective cover 3 are connected to the two driving members 4. In this embodiment, see Figure 1As shown, the tool holder plate 2 is installed on the upper end of the tool holder 1, and two driving members 4 are arranged on both sides of the upper end of the tool holder 1, which are used to connect with the two ends of the protective cover 3. The two driving members 4 work synchronously and can drive the protective cover 3 to rotate, so that the protective cover 3 covers the tool holder plate 2 to prevent the cutting fluid from splashing onto the tool handle and the proximity switch 8. The provided blowing mechanism can blow air to the tool handle of the tool 7 and the proximity switch 8, and can blow away the cutting fluid splashed onto the tool handle and the proximity switch 8.

[0024] See also Figure 1 As shown, the first tool positioning key slots 5 are arranged in a row, and the second tool positioning key slots 6 are arranged in a row and are arranged on one side of the first tool positioning key slot 5. The first tool positioning key slots 5 and the second tool positioning key slots 6 are both used to place the tool 7. The clamping mechanism is provided for the tool handle, so that the light-weight tool 7 can be separated from the robot when stored.

[0025] Further, as a preferred embodiment, the driving member 4 is a swing cylinder, and the protective cover 3 is connected to the swing cylinder. The swing cylinder can drive the protective cover 3 to rotate.

[0026] Further, as a preferred embodiment, a broken knife detection switch 9 is also included, and a broken knife detection switch 9 is also provided at the upper end of the tool holder plate 2. Among them, the swing cylinder, the proximity switch 8 and the broken knife detection switch 9 can all be connected to an external PLC controller, and the set broken knife detection switch 9 is used to detect whether the tool 7 is damaged (broken).

[0027] Further, as a preferred embodiment, the air blowing mechanism includes an air blowing pipeline 11, which is arranged at the upper end of the tool holder plate 2, and the air blowing pipeline 11 is provided with a plurality of air blowing holes facing the first tool positioning keyway 5 and the second tool positioning keyway 6. The tool holder 1 is also provided with a plurality of air blowing pipes 10, each of which faces a proximity switch 8. Among them, the air blowing holes provided on the air blowing pipeline 11 are used to remove the cutting fluid on the tool handle, and the air blowing pipe 10 is used to remove the cutting fluid on the proximity switch 8. Among them, the air blowing pipe 10 and the air blowing pipeline 11 can be connected to an external air supply device.

[0028] Further, as a preferred embodiment, the clamping mechanism includes a fixed block 12 and a plunger 13 disposed at one end of the fixed block 12, and the fixed block 12 is disposed on the tool holder plate 2. The fixed block 12 is connected to the tool holder plate 2 through a connecting member 14, wherein the connecting member 14 is a bolt, a locking screw or a connecting pin, etc., and is used to fix the fixed block 12 to the upper end of the tool holder plate 2. The plunger 13 has a certain elasticity and can squeeze the handle of the tool 7 to achieve clamping and fixing of the handle.

[0029] When in use, the protective cover 3 is first in a closed state. When the tool removal signal is turned on, the swing cylinder drives the protective cover 3 to rotate and open; the external air supply equipment starts working, and the blowing mechanism blows air to the tool handle and the proximity switch 8 to remove foreign matter on the surface; at the same time, the robot moves to the top of the required tool removal point, and then moves vertically downward to fit with the tool handle surface. After the tool pulling signal is turned on, the robot clamps the tool 7 and then moves vertically upward to a safe distance from the first tool positioning key groove 5 or the second tool positioning key groove 6, and then moves to contact the broken tool detection switch 9 to determine whether the tool 7 is damaged. If there is no damage, it can be moved to the processing area for processing.

[0030] When the tool 7 needs to be stored, the protective cover 3 is first driven by the swing cylinder to open, and the blowing mechanism is turned on. The robot clamps the tool 7 and moves it to the broken tool detection switch 9 to determine whether the tool 7 is damaged (if damaged, notify to replace the tool 7), and then moves to the first tool positioning key slot 5 or the second tool positioning key slot 6 where the tool 7 is required to be stored, and then moves vertically downward. If it is stored in the first tool positioning key slot 5, the robot clamps the tool 7 until it contacts the plunger 13, and the plunger 13 clamps the tool handle through elastic force, the robot's tool release signal is turned on, and the tool 7 can be fixed in the first tool positioning key slot 5; if it is stored in the second tool positioning key slot 6, the robot drives the tool handle to move vertically downward to a distance of 0.5 to 1 mm from the upper surface of the second tool positioning key slot 6, the tool release signal is turned on, and the tool 7 can fall into the second tool positioning key slot 6.

[0031] The above description is only a preferred embodiment of the present invention, and does not limit the implementation mode and protection scope of the present invention. For those skilled in the art, it should be aware that all solutions obtained by equivalent substitutions and obvious changes made using the description and illustrations of the present invention should be included in the protection scope of the present invention.
