Description

Technical Field

[0001] This utility model relates to the field of lathe machining technology, and in particular to a cutting tool for machining the inner arc of a lathe. Background Technology

[0002] When machining arcs on a conventional lathe, the traditional method is to first use a grooving tool to carve a groove, then prepare an arc forming tool according to the radius and machining accuracy requirements of the arc, and then manually refine the arc. Factors such as the radius of curvature of the arc and the starting and ending positions of the arc need to be precisely controlled manually. However, during the manual arc refining process, the controllability of the tool is poor, which can easily lead to problems such as inaccurate arc shape and poor surface roughness, making it difficult to meet the machining process requirements of high-precision arcs.

[0003] In view of this, the present invention proposes a cutting tool for turning the inner arc of a lathe. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the above-mentioned technology and provide a tool for machining arcs inside a lathe. The tool can achieve multi-angle control, accurately perform arc finishing, has high operational feasibility, and produces accurate arc shapes with high precision, thereby improving production stability and machining efficiency.

[0005] The specific details of the technical solution proposed in this application are as follows:

[0006] A cutting tool for turning an inner arc on a lathe includes a support assembly, an operating assembly, and a cutting tool body. The support assembly includes a tool holder and a rotatable tool turret mounted on the tool holder. The cutting tool body is mounted on the tool turret, and the tool turret is provided with an operating assembly that has locking and cutting functions. The operating assembly includes a locking component and a manual component. The locking component is connected to the manual component, and the cutting of the cutting tool body is achieved by rotating the locking component through the manual component.

[0007] Furthermore, the tool body is cylindrical in shape, and the end of the tool body is provided with a cutting edge that has a multi-directional cutting function.

[0008] Furthermore, the cutting edge includes multiple irregular arc-shaped cutting surfaces, each of which is a flat plane with clear boundaries formed by multiple cutting edges and arc-shaped contour edges.

[0009] Furthermore, the point where multiple cutting edges converge in the same direction forms the blade tip.

[0010] Furthermore, a flat area can be set in the connection area between the arc-shaped cutting surfaces to reduce friction with the workpiece, improve cutting safety and accuracy, and avoid tool wear.

[0011] Furthermore, the top of the locking component is provided with a concave slot, and the end of the manual component is inserted into the slot to rotate the locking component clockwise or counterclockwise.

[0012] Furthermore, one end of the locking component is threadedly connected to the tool holder, and the other end is engaged and abutted against the manual component.

[0013] Furthermore, the locking component is an internal hex bolt.

[0014] Furthermore, the tool holder is a square screw, which has a mounting hole for mounting the tool body and a locking hole for mounting the locking element. The mounting hole and the locking hole are perpendicular to each other.

[0015] Furthermore, the bottom of the tool holder is installed in the corresponding rod hole of the tool holder by a screw, and the tool holder is installed on the lathe tool post.

[0016] This utility model provides a cutting tool for turning internal arcs on a lathe, which has the following beneficial technical effects:

[0017] Through the coordinated design of the support components and the rotatable tool turret, multi-angle positioning of the tool body is achieved. The operating components integrate locking and cutting adjustment functions, simplifying the tool adjustment process during in-machine arc machining and significantly improving machining efficiency. The linkage structure of the manual component driving the locking component ensures tool stability during cutting and avoids accuracy deviations caused by machining vibration.

[0018] The precision and accuracy of the in-vehicle arc finishing obtained through the above-mentioned structural components are high, which can improve production stability and production quality.

[0019] By rotating the manual component in the operating assembly, the locking component is loosened, which in turn allows adjustment of the tool body extension length to accommodate cutting of different arc radii. This enables the cutting of arcs of different specifications and sizes. The operation is simple, reduces auxiliary time, and improves processing efficiency. Attached Figure Description

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0029] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] As attached Figure 1-6 As shown, this utility model provides a cutting tool for turning the inner arc of a lathe, including a support assembly 1, an operating assembly 2, and a cutting tool body 3. The support assembly 1 includes a tool holder 11 and a rotatable tool holder 12 disposed on the tool holder 11. The cutting tool body 3 is mounted on the tool holder 12, and the tool holder 12 is provided with an operating assembly 2 that has locking and cutting functions. The operating assembly 2 includes a locking member 21 and a manual member 22. The locking member 21 is connected to the manual member 22, and the cutting of the cutting tool body 3 is achieved by rotating the manual member 22 to rotate the locking member 21.

[0032] Obviously, this utility model provides a special tool for the inner arc of a lathe with a reasonable structure and convenient operation. By setting up the support component 1, the operation component 2 and the tool body 3 in a coordinated manner, it realizes efficient and high-precision cutting of the inner surface of the arc. In particular, the integrated design of locking and cutting adjustment functions through the operation component 2 simplifies the traditional lathe tool replacement and adjustment steps, and improves work efficiency and machining stability.

[0033] As an embodiment of this application, the support assembly 1 serves as a support and carrier for the operation of the cutting tool, including a bottom cutting bar 11 and a cutting table 12 located on the cutting bar 11. The cutting bar 11 is provided with a rod hole, and the cutting bar 11 is connected to the cutting table 12 through the rod hole.

[0034] Specifically, the tool holder 11 is rectangular in shape and is pressed and mounted on the lathe tool post 4.

[0035] The rod hole is a circular hole with a preset diameter, which can be used to install the rotatable tool holder 12. Preferably, the preset diameter of the rod hole is 8mm.

[0036] Furthermore, the tool holder 12 is a square screw, which has a mounting hole 121 for mounting the tool body 3 and a locking hole 122 for mounting the locking member 21. The mounting hole 121 and the locking hole 122 are arranged perpendicular to each other.

[0037] The square screw structure facilitates clamping and positioning. The design of the platform hole 121 and the locking hole 122 being perpendicular to each other allows the tool body 3 and the locking member 21 to be installed independently without affecting each other, which enhances the stability and adjustment accuracy of the overall structure and helps to achieve precise arc cutting.

[0038] Furthermore, the bottom of the tool holder 12 is installed in the corresponding rod hole of the tool holder 11 by a screw, as shown in the attached figure. Figure 5-6 As shown, the tool holder 11 is mounted on the lathe tool post 4.

[0039] The screw and rod hole are fitted together to ensure a stable and reliable connection between the tool holder 12 and the tool shank 11, while also facilitating disassembly and replacement. The tool shank 11 is mounted integrally on the lathe tool post 4, ensuring the rigidity and smooth operation of the entire tool system, making it suitable for high-intensity continuous machining tasks.

[0040] For example, see attached Figure 1 As shown, the screw on the tool holder 12 is inserted into the rod hole of the tool holder 11, the bottom of the screw extends out of the rod hole, the extended part of the screw is provided with external thread, and a fixing nut can be installed to complete the connection and fixation between the tool holder 12 and the tool holder 11.

[0041] As an example of this application, such as Figure 1-4As shown, a tool body 3 is mounted on the tool holder 12. The tool body 3 is cylindrical in shape, and a cutting edge 31 with multi-directional cutting function is provided at the end of the tool body 3.

[0042] The cylindrical tool body 3 is easy to install and rotate, while the multi-directional cutting edge 31 at the end enhances the tool's adaptability at different angles, enabling the lathe to flexibly meet the machining needs of various arc surfaces, improving machining flexibility and applicability.

[0043] like Figure 2-4 As shown, the cutting edge 31 includes multiple irregular arc-shaped cutting surfaces 32. Each arc-shaped cutting surface 32 is a flat plane with clear boundaries, formed by multiple cutting edges 33 and arc-shaped contour edges 34. The structure of the cutting edge 31 can effectively improve the uniformity of contact area distribution during the cutting process, reduce local stress concentration, thereby extending tool life and improving the quality of the cutting surface. In addition, the design of a flat plane with clear boundaries helps to form a smoother machined surface, meeting the requirements of high-precision machining.

[0044] For example, the blade 31 in this utility model includes three irregular arc-shaped cutting surfaces 32, each arc-shaped cutting surface 32 being composed of multiple ( Figure 2-4 Example 2-4) consists of a blade edge 33 and an arc-shaped profile edge 34.

[0045] Furthermore, the intersection of multiple cutting edges 33 extending in the same direction forms the cutting tip 35, which gives the tool good guidance and cutting sharpness, which is conducive to quickly cutting into the workpiece and maintaining a stable cutting path, further improving processing efficiency and surface finish.

[0046] As attached Figure 4 As shown, a flat area can be set in the connection area between the arc-shaped cutting surfaces 32, which can reduce friction with the workpiece, improve cutting safety and accuracy, and avoid tool wear.

[0047] Furthermore, the tool body 3 is made of well-prepared tungsten steel. The tool body 3 is inserted into the transversely arranged platform hole 121, and the extension length of the tool body 3 can be reasonably adjusted to adapt to different machining requirements.

[0048] As an embodiment of this application, the tool holder 12 is equipped with an operating component 2 that has locking and cutting functions. The operating component 2 includes a locking member 21 and a manual member 22. The top of the locking member 21 is provided with a concave slot, and the end of the manual member 22 is inserted into the concave slot to rotate the locking member 21 clockwise or counterclockwise.

[0049] The design of the locking element 21 with its concave groove and the manual element 22 provides the operating component 2 with good connection stability and controllability. Users can flexibly control the tightness of the locking element 21 via the manual element 22, enabling rapid adjustment and fixation of the tool, thus improving operational convenience and safety.

[0050] Furthermore, one end of the locking member 21 is threadedly connected to the tool holder 12, and the other end is engaged and abutted against the manual member 22.

[0051] The design of the locking component 21 ensures the firmness of the connection between the locking component 21 and the tool holder 12. At the same time, the manual component 22 enables quick disassembly and adjustment, balancing the stability of the connection and the flexibility of operation, making it suitable for production environments where machining parameters are frequently adjusted.

[0052] For example, the locking element 21 is a hex socket head cap screw. To enhance the locking effect, a nut can be provided at the connection between the hex socket head cap screw and the tool holder 12. The bottom end of the locking element 21 is threaded into the locking hole 122, and the top end is connected to the manual element 22 through a concave slot.

[0053] During the use of the locking component 21, the internal hex bolt is tightened downward by operating the manual component 22 until its end contacts the tool body 3.

[0054] Furthermore, the manual component 22 is a right-angled operating wrench. One end of the right-angled operating wrench is connected to the locking component 21 (concave groove), and the other end is a free end, which is equipped with an operating handle glove.

[0055] Specifically, during operation, by rotating the operating wrench left and right, the locking part 21 can move up and down within a short distance and rotate itself. The rotation of the locking part 21 drives the tool body 3 to move back and forth, performing the tool advance and retraction operation, thereby realizing the arc cutting process.

[0056] Compared with the prior art, the above-described embodiments of this utility model have the following beneficial technical effects:

[0057] Through the cooperative design of the support component 1 and the rotatable tool holder 12, the tool body 3 can be positioned at multiple angles. The operation component 2 integrates locking and cutting adjustment functions, which simplifies the tool adjustment process during in-machine arc machining and significantly improves machining efficiency. The linkage structure of the manual component 22 driving the locking component 21 ensures the stability of the tool during cutting and avoids accuracy deviation caused by machining vibration.

[0058] The precision and accuracy of the in-vehicle arc finishing obtained through the above-mentioned structural components are high, which can improve production stability and production quality.

[0059] By rotating the manual component 22 in the operating assembly 2, the locking component 21 can be loosened, thereby adjusting the extension length of the tool body 3 to adapt to cutting processes with different arc radii. Arcs of different specifications and sizes can be cut. The operation process is simple, reducing auxiliary time and improving processing efficiency.

[0060] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
