Milling cutters can be divided into cylindrical milling cutters, face milling cutters, end milling cutters, three-edge milling cutters, angle milling cutters, saw blade milling cutters and T-shaped milling cutters according to their shapes. These various types of milling cutters are widely used in the milling of various mechanical parts.

[0003] According to the Chinese patent with announcement number: CN219112988U, a milling tool includes a tool body, a first blade and a second blade, wherein the first blade is arranged at a first circumferential installation position of the tool body, the first blade has a first cutting edge, and the distance between the first cutting edge and the axis L of the tool body is H1; the second blade is arranged at a second circumferential installation position of the tool body, the second blade has a second cutting edge; the distance between the second cutting edge and the axis L of the tool body is H2, ΔH is the difference between H1 and H2, and ΔH is greater than zero.

[0004] In the above scheme, the cutter disc is installed on the front drive shaft of the milling equipment by using a keyway, which leads to the following disadvantages: when the cutter disc is installed by using a keyway, the keyway needs to cooperate with the key and fix the position between the key and the keyway. The overall process of replacing and installing the cutter disc can be roughly divided into five steps: removing the connection between the key and the keyway key, removing the cutter disc, replacing the cutter disc, connecting the key and the keyway, and fixing the key and the keyway. The replacement process is relatively cumbersome, which reduces the efficiency when replacing the turning and milling tools. Utility Model Content

[0005] The utility model aims to provide a turning and milling tool that is easy to replace, so as to solve the problem that the replacement process is complicated and the efficiency when replacing the turning and milling tool is reduced.

[0006] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a turning and milling tool that is easy to replace, including a turning and milling tool handle, the turning and milling tool handle is fixedly installed on one side of the turning and milling cutter head, one end of the turning and milling tool handle is provided with a docking groove, the interior of the docking groove is detachably provided with a lathe rotating shaft, the surface of the turning and milling tool handle is provided with two mounting holes, the surface of the lathe rotating shaft is provided with two sleeve grooves, the interior of the sleeve groove is provided with a pressing column that is slidably inserted, the inner bottom surface of the sleeve groove is provided with a storage groove, the bottom end of the pressing column is fixed with a lifting rod, the lifting rod and the storage groove are slidably inserted, the surface of the lifting rod is surrounded by a spring, one end of the spring is fixed to the inner bottom surface of the sleeve groove, and the other end of the spring is fixed to the bottom surface of the pressing column.

[0011] Preferably, a fixing groove is provided on the surface of the rotating shaft of the lathe, and a sealing ring is fixed inside the fixing groove.

[0012] Compared with the prior art, the easy-to-replace turning and milling tool using the above technical solution has the following beneficial effects:

[0013] 1. Before turning and milling, the staff will select the turning and milling tool holder and the turning and milling tool head of corresponding specifications and sizes to install on the lathe rotating shaft. During this process, the pressing column will be pressed down first, and the pressing column will slide downward inside the sleeve groove, and drive the lifting rod to slide downward inside the storage groove, and compress the spring, and then install the lathe rotating shaft into the docking groove. After one end of the lathe rotating shaft contacts the inner side of the docking groove, the central axis of the mounting hole and the sleeve groove are in the same straight line. At this time, the compressed spring will push the pressing column inside the sleeve groove upward and move into the inside of the mounting hole, and the installation and replacement of the turning and milling tool can be completed. The overall process only requires three steps: pressing the pressing column, removing the turning and milling tool holder, and installing a new turning and milling tool holder, which increases the efficiency of replacing the turning and milling tool holder;

[0014] 2. When the milling cutter handle and the lathe rotating shaft are installed together, the limit column will slide inside the limit groove, ensuring that the sleeve groove can be moved to the position corresponding to the mounting hole while also increasing the firmness of the position between the milling cutter handle and the lathe rotating shaft;

[0015] 3. When the milling cutter head rotates, the blade will be driven to rotate synchronously, so that the alloy parts can be milled. When the edge of the blade curls, the staff will first unscrew the fixing bolt out of the thread groove, and then remove the curled blade. After replacing the intact blade, the fixing bolt will be passed through the penetration hole and screwed into the thread groove again, so that the blade can be replaced at any time, extending the service life of the milling cutter head.

[0016] 4. When the lathe rotating shaft is installed inside the docking groove, the sealing ring will be squeezed and fit on the inner wall of the docking groove, which can increase the sealing between the lathe rotating shaft and the docking groove, and prevent the water used for cooling or the debris produced by milling from entering the docking groove during the turning and milling process.
