Specifically, the first mounting groove 131 is located on the side surface of the clamping portion 13 and extends to the bottom surface of the clamping portion 13. The second mounting groove 132 is located at both ends of the bottom surface of the clamping portion 13 and extends to the side surface of the clamping portion 13. The clamping portion 13 is provided with a first water outlet 133, a second water outlet 134 and a third water outlet 135. The first water outlet 133 is located on the bottom surface of the clamping portion 13, and the first water outlet 133 is located in the extension direction of the first mounting groove 131. The second water outlet 134 and the third water outlet 135 are located on both sides of the clamping portion 13, and the second water outlet 134 and the third water outlet 135 are located in the extension direction of the second mounting groove 132. The clamping portion 13 also includes a nozzle 136, a soft plug 137 and a nozzle fixing screw 1361. The soft plug 137 is used to block the non-working water outlet. When the nozzle 136 is inserted into the water outlet, the nozzle 136 is connected to the water outlet. The nozzle fixing screw 1361 restricts the nozzle 136 to prevent the nozzle 136 from being detached due to the pressure of the coolant flow channel 14.

[0028] The fixture 1 is provided with a coolant flow channel 14 , and the coolant flow channel 14 is connected to the water inlet 111 and a plurality of water outlets.

[0029] The utility model discloses a cooling turning tool structure and fixture installation and working process:

[0030] Place the turning tool 2 in the first installation groove 131, adjust the position of the turning tool 2 so that the tip of the turning tool 2 is exposed from the first installation groove 131 and fix the turning tool 2 with the turning tool fixing screw 21, install the nozzle 136 at the first water outlet 133, plug the second water outlet 134 and the third water outlet 135 with the soft plug 137, and limit the nozzle 136 with the nozzle fixing screw 1361;

When the tip of the turning tool 2 is biased toward the second water outlet 134, the nozzle 136 is installed at the second water outlet 134, the first water outlet 133 and the third water outlet 135 are blocked with the soft plug 137, and the nozzle 136 is restricted with the nozzle fixing screw 1361; when the tip of the turning tool 2 is biased toward the third water outlet 135, the nozzle 136 is installed at the third water outlet 135, the first water outlet 133 and the second water outlet 134 are blocked with the soft plug 137, and the nozzle 136 is restricted with the nozzle 136 fixing screw 1361.

[0032] The installation condition of the turning tool 2 in the first installation groove 131 or the second installation groove 132 is adjusted so that the coolant sprayed from the nozzle 136 can be sprayed onto the tip of the turning tool 2, so that the turning tool 2 has multiple working positions.

[0033] When the turning tool 2 is installed, the fixture 1 is docked with the lathe through the docking interface 112, and the fixture 1 is installed by the cooperation of the positioning block 113 with the lathe.

[0034] When the machine tool is working, the coolant flows from the water inlet 111 to the water outlet through the coolant flow channel 14, and is guided by the nozzle 136 so that the coolant is sprayed on the tip of the turning tool 2 to achieve a cooling effect.

[0035] The utility model is beneficial in that, by coordinating the positions of the water outlet and the mounting groove, the coolant is sprayed onto the tip of the turning tool 2 through the water inlet 111, the coolant flow channel 14, and the water outlet, thereby reducing the temperature of the turning tool 2 during operation, increasing the service life of the turning tool 2, improving the surface finish of the processed workpiece and the product precision, and thus improving the product qualification rate.
