[0002] The turning tool head is a tool used on a mechanical lathe, usually made of carbide or high-speed steel. It is mainly used for turning, that is, by rotating the workpiece and using the turning tool head to cut and trim the workpiece surface, usually made of carbide or high-speed steel. It is mainly used for turning, that is, by rotating the workpiece and using the turning tool head to cut and trim the workpiece surface.

[0003] When installing some existing turning tool heads, workers usually use appropriate tools to thread the tool head and the tool rod through bolts. However, if the tool head is only fixed to the tool rod through bolts, the bolts fixing the tool head and the tool rod may become loose after long-term use, causing the tool head body to become loose, resulting in accidents during use, affecting the user's use and safety. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and provide a high-strength turning tool head.

[0006] As a preferred embodiment, the limiting mechanism includes a knife rod, one end surface of the knife rod is fixedly connected to the inner wall of the fixing ring, both side surfaces of the fixing ring are fixedly connected to the limiting shell, and one side of the inner wall of the two limiting shells is fixedly connected with an elastic block.

[0007] As a preferred implementation, one side of the fixing bracket is fixedly connected to one end of the cutter head body, and the fixing bracket and the inner walls of the multiple slots formed on the cutter head body are bolted together.

[0008] As a preferred embodiment, the cutter head body is threadedly fixed via a fixing frame, a bolt and a thread groove formed on the inner wall of one end of the cutter rod.

[0009] As a preferred embodiment, the surface of the cutter head body is fixedly connected to the inner wall of the outer ring, and sliding blocks are fixedly connected to the surfaces on both sides of the outer ring.

[0011] As a preferred implementation, one end of the two sliding blocks is provided with a smooth portion.

[0012] As a preferred implementation, the inner walls of the threaded grooves formed on the two sliding blocks and the limiting shell are both threadedly connected with fixing members, and the outer end surfaces of the two fixing members are both fixedly connected with handles.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. After the slider is limited by the installed reinforcement mechanism, the user can fix the limit shell and the slider again by turning the handle and the fixing piece, thereby increasing the stability between the cutter head body and the cutter bar during use. This method can not only ensure that the cutter head will not loosen or move during use, and improve the stability and accuracy of cutting, but the secondary fixation can also prevent accidental loosening or falling off, thereby improving the safety of use.

Once the slider is limited, the subsequent installation process will be more simplified. The user does not need to perform positioning and fixing operations when installing the bolts, but can directly install it, which can further improve the installation efficiency.

[0016] 3. Through the installed limiting mechanism, since the elastic block has a certain degree of deformability, the cutter head body can be pulled outward with a little force, so that the surface of the elastic block is out of the limiting groove. In this way, the user can quickly remove the cutter head for replacement, saving time and improving work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 - Figure 3 As shown, the utility model provides a technical solution: a high-strength turning tool head, including: a reinforcement mechanism 1, the reinforcement mechanism 1 includes a tool head body 11, a fixing frame 12 is arranged at one end of the tool head body 11, and bolts 13 are arranged on the inner walls of multiple threaded grooves opened by the fixing frame 12, and a limiting mechanism 2 is arranged on the surface of the bolt 13, an outer ring 14 is arranged on the surface of the tool head body 11, and two sliders 15 are arranged on the surface, and limiting grooves 16 are arranged on the other sides of the two sliders 15, and smooth portions 17 are arranged on one end of the two sliders 15.

[0027] In this embodiment, the fixing frame 12 is fixedly connected to one end of the cutter head body 11 through one side, and the inner walls of the multiple slots opened on the fixing frame 12 and the cutter head body 11 are all connected with bolts 13, and the cutter head body 11 is threadedly fixed through the fixing frame 12, the bolts 13 and the threaded groove opened on the inner wall of one end of the tool rod 21, and the cutter head body 11 is threadedly fixed through the fixing frame 12, the bolts 13 and the threaded groove opened on the inner wall of one end of the tool rod 21; using bolts 13 to connect the cutter head body 11 and the fixing frame 12 can provide higher connection strength and stability. The tightening force of the bolts 13 can ensure that the cutter head body 11 will not loosen or move during the turning process, thereby improving the processing quality and efficiency;

[0028] The surface of the cutter head body 11 is fixedly connected to the inner wall of the outer ring 14, and the surfaces of both sides of the outer ring 14 are fixedly connected with sliders 15. The surfaces of the two sliders 15 are slidably connected with the corresponding card slots opened in the limit shell 23. One side of the two sliders 15 is provided with a limit groove 16, and the limit groove 16 is fixedly connected with the surface of the elastic block 24. One end of the two sliders 15 is provided with a smooth portion 17; when the user installs, first, the two sliders 15 can be inserted into the limit shell 23. When one end of the slider 15 contacts the elastic block 24 in the limit shell 23, the user only needs to apply a little force to make the smooth portion 17 of the slider 15 pass through the elastic block 24. The elastic card block 24 is pushed and then pushed to make the elastic card block 24 snap into the limiting groove 16 provided therein, thus completing the preliminary limiting and installation. When the slider 15 is limited, it can also help with the subsequent installation. The elastic card block 24 and the limiting groove 16 in the limiting shell 23 can not only ensure the accurate positioning of the slider 15 during the installation process, but also avoid the problems caused by inaccurate alignment. Once the slider 15 is limited, the subsequent installation process will be more simplified. When installing the bolt 13, the user does not need to perform alignment and fixing operations, but can directly install it, which can further improve the installation efficiency.

[0029] The inner wall of the threaded groove formed by the two sliders 15 and the limit shell 23 is threadedly connected with a fixing member 18, and the outer end surface of the two fixing members 18 is fixedly connected with a handle 19; when the slider 15 is limited, the user can fix the limit shell 23 and the slider 15 for a second time by turning the handle 19 and the fixing member 18, thereby increasing the stability between the cutter head body 11 and the shank 21 during use. This method can not only ensure that the cutter head will not loosen or shift during use, and improve the stability and accuracy of cutting, but the secondary fixation can also prevent accidental loosening or falling off, thereby improving the safety of use. Under high-speed cutting or heavy-load conditions, the fixing stability of the cutter head is very important, so as to avoid the loosening of the bolts 13 fixing the cutter head body 11 and the shank 21 due to long-term use, resulting in the loosening of the cutter head body 11 and the occurrence of accidents during use.

[0030] Example 2

[0031] like Figure 1 - Figure 4 As shown, the limiting mechanism 2 includes a knife rod 21, one end surface of the knife rod 21 is fixedly connected to the inner wall of the fixing ring 22, both side surfaces of the fixing ring 22 are fixedly connected to the limiting shells 23, and one side of the inner wall of the two limiting shells 23 is fixedly connected to an elastic block 24.

[0032] In this embodiment, through the cooperation of the above components, when the user disassembles the cutter head body 11, the user can first rotate the handle 19 in the opposite direction to disengage the fixing member 18 from the threaded groove formed by the slider 15 and the limiting shell 23. Since the elastic block 24 has a certain degree of deformability, it is provided that the cutter head body 11 can be pulled outward with a slight force to disengage the surface of the elastic block 24 from the limiting groove 16, so that the cutter head body 11 can be removed and replaced.

[0033] Working principle:

[0034] like Figure 1 - Figure 4 As shown, when installing, the user can first insert the two sliders 15 into the limiting shell 23. When one end of the slider 15 contacts the elastic block 24 in the limiting shell 23, the user only needs to use a little force to make the smooth portion 17 of the slider 15 pass through the elastic block 24, and then continue to push the block to make the elastic block 24 snap into the limiting groove 16 provided therein, thereby completing the preliminary limiting and installation. Once the slider 15 is limited, the subsequent installation process will be more simplified. When installing the bolt 13, the user does not need to perform alignment and fixing operations, but can directly install it. After the slider 15 is limited, the user can fix the limiting shell 23 and the slider 15 for a second time by rotating the handle 19 and the fixing member 18, thereby increasing the stability between the cutter head body 11 and the cutter rod 21 during use.

[0035] When the user disassembles the cutter head body 11, he can first rotate the handle 19 in the opposite direction to disengage the fixing part 18 from the threaded groove formed by the slider 15 and the limiting shell 23. Since the elastic block 24 has a certain degree of deformability, the cutter head body 11 can be pulled outward with a slight force to disengage the surface of the elastic block 24 from the limiting groove 16, so that the cutter head body 11 can be removed and replaced.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
