[0002] Rotary tools for machining, especially milling cutters, are important tools in the field of machining. The design of this tool is based on its multi-tooth rotation characteristics. Each tooth is equivalent to a turning tool fixed on the rotating surface of the milling cutter, so that it can quickly and effectively remove excess material on the workpiece when rotating at high speed.

[0003] The existing rotary tool includes a tool handle, a cutting part and a clamping part, so that it can effectively utilize the combination of rotational motion and feed motion during use, and realize the cutting and forming of the workpiece through the interaction between the cutting part and the workpiece. However, during long-term use, the cutter head will produce a certain amount of wear. If it continues to be used, the use effect and accuracy will be reduced to a certain extent. Therefore, the operator needs to manually disassemble the cutter head and then replace it with a new cutter head to ensure the use effect of the tool during rotation. Therefore, the present application provides a rotary tool for machining to meet the needs. Utility Model Content

[0004] The purpose of the present application is to provide a rotary tool for machining, which solves the problem of complicated and cumbersome tool head replacement steps in the prior art and achieves the purpose of simplifying the tool head replacement operation.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a rotary tool for machining, comprising a tool handle and a cutting tool head arranged below the tool handle, wherein a clamping member is fixedly connected to the inside of the tool handle, and the bottom of the clamping member forms an outer ring fixing portion through an opening of a plug-in groove, an inner ring fixing member is fixedly connected to the inside of the plug-in groove, and the plug-in groove and the inner ring fixing member form an annular plug-in groove body, and a tool head plug-in member is fixedly connected to the top of the cutting tool head, and the tool head plug-in member can be plugged into the annular plug-in groove body The plug-in structure of the tool head connector and the annular plug-in slot is used to splice the tool handle and the cutting tool head, a plurality of mounting holes are provided on the circumferential side of the inner ring fixing part, and an electric push rod is fixedly connected to the inside of the mounting hole body, a plurality of penetrating plug-in limit grooves are provided on the circumferential side of the tool head connector, and the free end of the electric push rod can be plugged into the inside of the plug-in limit groove, and the plug-in structure of the electric push rod and the plug-in limit groove is used to limit the relative position between the annular plug-in slot body and the tool head connector.

[0006] Preferably, a plurality of elastic members are fixedly connected inside the annular plug-in slot, and a same buffer member is fixedly connected to the bottom of the plurality of elastic members.

[0007] Preferably, a plurality of limiting holes are opened inside the outer ring fixing part, and an electric slide rail is fixedly connected inside the limiting hole, a supporting sleeve is fixedly connected to the sliding seat of the electric slide rail, and the electric slide rail is used to drive the supporting sleeve to move linearly.

[0008] Preferably, the electric push rod and the supporting sleeve are located on the same central axis, the free end of the supporting sleeve is provided with a splicing interface, and the inner diameter of the splicing interface is larger than the diameter of the free end of the electric push rod.

[0009] Preferably, an annular protective sleeve is fixedly inserted inside the plug-in limit groove, and the annular protective sleeve is a hollow structure with openings at both ends.

[0011] In summary, the technical effects and advantages of the utility model are:

[0012] 1. The utility model has a reasonable structure. By providing an annular plug-in groove body and a cutter head plug-in component, when it is used for a long time, the electric push rod can be directly controlled by an external controller, so that it retracts under force, and then changes its own extension length so that it is completely stored in the interior of the mounting hole body. At this time, the plug-in structure of the electric push rod and the plug-in limit groove will disappear, and the cutter head plug-in component will also be released from the restriction, so that it can fall under its own gravity and the cutting head, thereby quickly completing its disassembly steps, so that it can independently replace or maintain the cutting head, and then simplify the overall operation steps.

[0013] 2. In the utility model, by providing a supporting sleeve, during its use, the electric slide rail can be controlled by an external controller, so that the electric slide rail effectively pushes the supporting sleeve to move. At this time, the supporting sleeve will change its own position, thereby disengaging from the limiting hole body and entering the interior of the annular plug-in groove body, and effectively plugging into the interior of the plug-in limiting groove. At this time, due to the setting of the splicing interface and the size of the electric push rod itself, when the supporting sleeve is plugged into the interior of the plug-in limiting groove, it will be synchronously plugged into the free end of the electric push rod, thereby enabling the electric push rod and the supporting sleeve to be docked, so that the electric push rod and the supporting sleeve form a plug-in structure with the plug-in limiting groove from both sides, thereby improving the limiting and fixing effect of the overall tool head connector.

[0026] Combine the following Figure 1-4 The embodiment shown describes the technical solution of the utility model:

[0027] The tool holder 1 includes a tool handle 1 and a cutting tool head 18 disposed below the tool handle 1. A clamping member 2 is fixedly connected to the inside of the tool handle 1, and the bottom of the clamping member 2 forms an outer ring fixing portion 5 through a plug-in slot 3. An inner ring fixing member 4 is fixedly connected to the inside of the plug-in slot 3, and the plug-in slot 3 and the inner ring fixing member 4 form an annular plug-in slot body. A tool head plug-in member 6 is fixedly connected to the top of the cutting tool head 18, and the tool head plug-in member 6 can be plugged into the inside of the annular plug-in slot body. The tool head plug-in member 6 and the annular plug-in slot body are connected to each other. The plug-in structure of the plug-in slot body is used to splice the tool handle 1 and the cutting bit 18, a plurality of mounting holes are opened on the peripheral side of the inner ring fixing part 4, and an electric push rod 7 is fixedly connected to the inside of the mounting hole body, a plurality of penetrating plug-in limit grooves 8 are opened on the peripheral side of the tool head plug-in part 6, and the free end of the electric push rod 7 can be plugged into the inside of the plug-in limit groove 8, and the plug-in structure of the electric push rod 7 and the plug-in limit groove 8 is used to limit the relative position between the annular plug-in slot body and the tool head plug-in part 6.

[0028] Before use, the appropriate cutting head 18 can be directly rotated, and the head connector 6 on the cutting head 18 can be aligned with the annular plug-in groove body, and the cutting head 18 can be directly pushed, so that the head connector 6 can be quickly plugged along the annular plug-in groove body under the action of its thrust. When the head connector 6 is plugged into the inside of the annular plug-in groove body, the electric push rod 7 can be directly controlled by the external controller, so that the free end of the electric push rod 7 will be effectively extended, and then inserted into the inside of the annular plug-in groove body, and quickly plugged into the inside of the plug-in limit groove 8. At this time, the plug-in structure between the electric push rod 7 and the plug-in limit groove 8 limits the position of the head connector 6, so that the tool handle 1 and the cutting head 18 complete the splicing operation. At this time, the tool handle 1 can be directly connected to the machine tool spindle to transmit torque and rotational power, and the cutting and forming of the workpiece can be achieved through the interaction between the cutting part and the workpiece.

[0029] A plurality of elastic members 13 are fixedly connected inside the annular plug-in slot, and a common buffer member 14 is fixedly connected to the bottom of the plurality of elastic members 13 .

[0030] When the cutter head connector 6 is inserted into the annular plug-in slot, the cutter head connector 6 can effectively contact the buffer 14. At this time, the buffer 14 will buffer the plug-in force of the cutter head connector 6 and evenly apply the buffered force to the elastic member 13, so that the elastic member 13 is deformed and shortened under the action of its force, thereby ensuring the stability of the cutter head connector 6 during the plug-in period.

[0031] A plurality of limiting holes 10 are provided inside the outer ring fixing portion 5, and an electric slide rail 11 is fixedly connected inside the limiting hole 10, a supporting sleeve 12 is fixedly connected to the sliding seat of the electric slide rail 11, and the electric slide rail 11 is used to drive the supporting sleeve 12 to move linearly, the electric push rod 7 and the supporting sleeve 12 are located on the same central axis, a splicing interface is provided at the free end of the supporting sleeve 12, and the inner diameter of the splicing interface is larger than the free end diameter of the electric push rod 7.

[0032] During its use, the electric slide rail 11 can be directly controlled by an external controller, so that the electric slide rail 11 can effectively push the supporting sleeve 12 to move. At this time, the supporting sleeve 12 will change its own position, thereby disengaging from the limiting hole body 10 and entering the interior of the annular plug-in groove body, and effectively plugging into the interior of the plug-in limiting groove 8. At this time, due to the setting of the splicing interface and the size of the electric push rod 7 itself, when the supporting sleeve 12 is plugged into the interior of the plug-in limiting groove 8, it will be synchronously plugged into the free end of the electric push rod 7, thereby making the electric push rod 7 and the supporting sleeve 12 docking operation, so that the electric push rod 7 and the supporting sleeve 12 form a plug-in structure with the plug-in limiting groove 8 from both sides, thereby improving the limiting and fixing effect of the overall tool head connector 6.

[0033] An annular protective sleeve 9 is fixedly inserted inside the plug-in limit groove 8, and the annular protective sleeve 9 is a hollow structure with two ends open. The inner diameter of the annular protective sleeve 9 is larger than the diameter of the electric push rod 7 and the supporting sleeve body 12, and the annular protective sleeve 9 is made of rubber material.

[0034] The provision of the annular protective sleeve 9 can effectively protect the plug-in limit groove 8, so that the electric push rod 7 and the supporting sleeve 12 will directly contact the annular protective sleeve 9 when plugged in, thereby ensuring the service life of the plug-in limit groove 8. At the same time, due to the rubber material of the annular protective sleeve 9, the friction of its plug-in structure is also increased to a certain extent, making it more stable during plug-in and fixing, avoiding the possibility of it falling off.

[0035] The bottom of the buffer 14 is provided with a mounting recess, and the interior of the mounting recess is fixedly connected with a magnetic attraction plate 15 , the top of the tool head connector 6 is fixedly connected with a magnetic attraction member 16 , and the buffer 14 is adapted to the magnetic attraction member 16 .

[0036] When the cutter head connector 6 is plugged into the annular plug-in slot under force, the magnetic attraction member 16 on the cutter head connector 6 will be effectively fixed to the magnetic attraction plate 15 by magnetic attraction, and its magnetic attraction force will improve its overall stability of use to a certain extent, avoiding the possibility of the cutter head connector 6 falling off.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
