[0002] In the field of mechanical manufacturing, the most common is CNC lathe, and various turning tools are installed on CNC lathes according to needs. Turning tool is a tool with a cutting part used for turning processing. Turning tool is one of the most widely used tools in cutting processing. The working part of the turning tool is the part that produces and processes chips, including the blade, the structure to break or roll up the chips, the space for chip removal or storage, the channel for cutting fluid and other structural elements.

[0003] The most common one is the grooving cutter. When the grooving cutter processes the workpiece, it is generally divided into rough processing and fine processing. After rough processing, the grooving cutter on the tool holder needs to be replaced and then fine processing is performed. Frequent replacement of grooving cutters often leads to inaccurate positioning, resulting in serious wear of the grooving cutter. When replacing the grooving blade, the tool needs to be re-aligned, which is time-consuming and labor-intensive. Therefore, a double-headed grooving cutter with internal cooling is required.

For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0027] The following is combined with Figure 1-5 This application is described in further detail.

[0028] refer to Figure 1 A double-ended slotting tool with internal cooling is shown, comprising: a tool body, the tool body comprising a tool seat 1, a tool handle 2 and two slotting blades 3 (the slotting blades can be made of high-speed steel, cemented carbide and cubic boron nitride, etc.), the tool handle 2 is arranged at one end of the tool seat 1, and two mounting positions 15 are arranged on the tool seat 1. The two slotting blades 3 are respectively arranged on the two mounting positions 15, and the cutting ends of the two slotting blades 3 extend to the outside of the suspended end of the tool seat 1. In this way, by arranging two mounting positions 15 on the tool seat 1, two slotting blades 3 of different processing types (rough processing, fine processing, etc.) can be installed. There is no need to frequently replace the slotting blades 3, which saves processing time and can save a tool position for the machine tool tool magazine.

[0029] refer to Figure 1 and 2 As shown, the suspended end of the tool holder 1 is a multi-layer structure, which includes a blade mounting layer 11 and a deformation layer arranged adjacent to each other. The mounting position 15 is placed on the blade mounting layer 11, and the mounting position 15 is connected with the gap between the blade mounting layer 11 and the deformation layer. The deformation layer is used to deform toward the blade mounting layer 11 to lock the groove blade 3. In this way, a layered structure is adopted to make the deformation layer deform toward the blade mounting layer 11 to extrude one end of the groove blade 3 and lock the groove blade 3 on the blade mounting layer 11.

[0030] refer to Figure 2 and 3As shown, a partition groove 4 is provided on the blade seat 1, and the partition groove 4 divides the deformation layer into two mounting parts 12. The two mounting parts 12 are respectively adapted to two mounting positions 15. Adjustment components are provided on the two mounting parts 12. The adjustment components are used to deform the corresponding mounting part 12 toward the blade mounting layer 11. In this way, the partition groove 4 is used to divide the deformation layer into two mounting parts 12, so that each of the groove blades 3 is deformed and locked, so that the two deformation locking pressure surfaces do not affect each other, and one of the groove blades 3 can be replaced at any time.

[0031] refer to Figure 3 As shown, the adjustment component is a bolt 5, which passes through the corresponding mounting portion 12 and is threadedly connected to the blade mounting layer 11. In this way, the bolt 5 is threadedly connected to the blade mounting layer 11. When the bolt 5 is rotated, the mounting portion 12 is deformed, moving closer to or away from the blade mounting layer 11, which is convenient and quick.

[0032] refer to Figure 1 and 2 As shown, the multi-layer structure also includes a water-cooling layer 13 arranged on the side of the deformation layer away from the blade mounting layer 11 (in actual use, the dividing groove 4 runs through the water-cooling layer 13, dividing the water-cooling layer 13 into two parts), and two internal cooling channels are arranged on the water-cooling layer 13, and the water outlets 6 of the two internal cooling channels respectively point to the cutting ends of the two slot blades 3. In this way, by arranging the water-cooling layer 13 on the side of the deformation layer away from the blade mounting layer 11, without interfering with the deformation of the deformation layer to lock the slot blade 3, the cutting ends of the two slot blades 3 are cooled respectively through the two internal cooling channels inside the water-cooling layer 13.

[0033] refer to Figure 3 and 4 As shown, in order to improve the installation efficiency, the knife body also includes a mounting plate 7 arranged between the knife seat 1 and the knife handle 2. The diameter of the mounting plate 7 is larger than the knife seat 1 and the knife handle 2, so that the knife body can be easily installed and positioned.

[0034] refer to Figure 4 As shown, the cutter body is provided with a mounting hole 8 inwardly from the suspension end of the cutter handle 2 , and the interior of the cutter body has a mounting space for easy installation, and a water cooling pipeline etc. can be installed in the mounting hole 8 .

[0035] refer to Figure 4 As shown, a positioning groove 21 is provided on the ring side of the suspension end of the handle 2, so that the installation angle of the knife body can be easily positioned when the knife body is installed.

[0036] refer to Figure 1 and 5 As shown, in order to increase the locking force, a groove 31 is provided at one end of the groove blade 3 close to the mounting portion 12, and a protrusion 14 adapted to the groove 31 is provided on the mounting portion 12. When locking the groove blade 3, the protrusion 14 is inserted into the groove 31 to lock the groove blade 3.

[0037] In summary, by providing two mounting positions 15 on the tool holder 1 for mounting two slotting blades 3 of different processing types, it is not necessary to frequently replace the slotting blades 3, thus saving processing time and saving a tool position for the machine tool magazine;

[0038] The present application adopts a multi-layer structure, and adopts a bolt 5 to be threadedly connected with the blade mounting layer 11. When the bolt 5 is rotated, the mounting portion 12 is deformed, and moves closer to or away from the blade mounting layer 11, so as to lock or loosen the slot blade 3, which is convenient and quick.

[0039] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
