Description

Technical Field

[0001] This application belongs to the technical field of cutting tools, and particularly relates to a woodworking cutting tool. Background Art

[0002] During the production process of wooden furniture, since there are certain edges and corners on the edges of the furniture, it is necessary to mill the edges of the wooden furniture to remove the edges and corners, so that the edges become smooth or present a specific shape to meet the needs of consumers. In the prior art, generally, a carpenter uses a manual circular arc knife to perform manual planing on the edge of the furniture. The manual planing work efficiency is relatively low, and the planing effect is not good, and it is easy to produce inconsistent edge arcs.

[0003] The patent with the publication number CN214687058U discloses a woodworking milling cutter, which includes a cutter body, a cutter handle fixedly connected to the cutter body, and a cutter blade connected to the cutter body. A cutter groove for installing the cutter blade is opened on the side wall of the cutter body. The cutter blade includes a cutting edge portion, an installation portion, and a connecting portion connecting the cutting edge portion and the installation portion. An installation groove for inserting the installation portion is opened on the groove wall of the cutter groove, and the installation groove communicates with the side wall of the cutter body close to the cutter handle. A limiting block is detachably connected to the cutter handle. The limiting block includes a limiting portion and an abutting portion. When the limiting block is installed on the cutter handle, the limiting portion abuts against the side wall of the connecting portion away from the installation portion, and the abutting portion abuts against the side wall of the connecting portion close to the cutter handle.

[0004] The above patent is fixed through the cooperation of a fixing nut and a limiting block. Although the fixing effect can be achieved, the fixing effect is poor and it is easy to loosen, and improvement is needed. Summary of the Utility Model

[0005] The purpose of this application is to provide a woodworking cutting tool that can solve the above problems.

[0006] The purpose of this application is to provide a woodworking cutting tool, including:

[0007] A cutter handle;

[0008] A cutter body, detachably arranged on the cutter handle, and a cutter blade is arranged on the cutter body;

[0009] An installation assembly, arranged on the cutter handle;

[0010] Wherein, the cutter body is arranged on the cutter handle through the installation assembly.

[0011] Using the above-mentioned woodworking cutting tool, by setting up the installation component, the woodworking cutting tool of the present application can more effectively fix the tool body on the tool handle, reduce the loosening phenomenon, and improve the stability and safety during the cutting process. Although the fixing effect is enhanced, the present application still retains the detachable design of the tool body. When the blade is worn and needs to be replaced or maintained, the user can easily remove the tool body from the tool handle, perform the necessary operations and then reinstall it, which is convenient and fast. Due to the improvement of the fixing effect, the woodworking cutting tool can maintain a more stable posture during the cutting process, reduce the cutting error caused by vibration or loosening, and thus improve the cutting accuracy and the quality of the workpiece.

[0012] Further, the installation component includes:

[0013] A threaded section, provided on the tool handle;

[0014] A nut, provided on the tool handle and adapted to the threaded section, and one end of the nut is provided with an outwardly extending extension ring;

[0015] A limiting member, provided at the bottom of the extension ring and located between the nut and the tool body, and one end of it is provided with a limiting opening adapted to the extension ring;

[0016] Wherein, the limiting opening is annular, and an elastic member is further provided between the nut and the limiting member.

[0017] The threaded section is provided on the tool handle, providing a threaded connection basis for the nut. By rotating the nut, the tool body can be precisely installed and fastened along the threaded section. One end of the nut is provided with an outwardly extending extension ring, which increases the surface area of the nut and also provides a platform for subsequent installation. As a part of the nut, the outwardly extending structure of the extension ring provides an installation and fixing position for the limiting member. The limiting member is provided at the bottom of the extension ring and is adapted to the extension ring through the limiting opening at one end. The limiting opening is annular and can be tightly sleeved on the extension ring. The elastic member is provided between the nut and the limiting member, playing a role of buffering and shock absorption. During the cutting process, the elastic member can absorb part of the vibration and impact force, reducing the damage to the tool body and the tool handle. At the same time, the existence of the elastic member can also allow the nut to have a small displacement to a certain extent when subjected to external forces, thereby reducing the stress concentration caused by rigid connection.

[0018] In the present application, when the nut is tightened, the nut applies pressure to the elastic member, and the elastic member is compressed, so that the end faces in contact with the limiting member are fitted together and clamp the tool handle, thereby increasing the pre-tightening force between the nut and the threaded section of the tool handle. When the tool handle and the nut are subjected to strong vibration and irregular strong force fluctuations, they are not likely to loosen and fall off, and the service life is extended.

[0019] Further: One end of the limiting member away from the limiting opening is provided with a protective pipe fitting, and one end of the protective pipe fitting is in contact with the elastic member.

[0020] The protective pipe fitting functions to protect the elastic member, preventing the inner wall of the elastic member from directly contacting the threaded section, protecting the elastic member from thread wear, thus effectively avoiding the jamming of the elastic member and also preventing the displacement of the elastic member within the limiting member.

[0021] Furthermore, a circular chamfer is provided at one end of the elastic member in contact with the protective pipe fitting. The other end of the elastic member fits against the inner wall of the limiting member, and a groove is provided inside the limiting member. The groove is adapted to the elastic member and is an arc-shaped groove.

[0022] The provision of the circular chamfer and the arc-shaped groove enables the two to fit more easily. Moreover, the arc-shaped structure has the function of automatically adjusting the position, keeping the nut and the tool shank always on the same axis. In addition, it also has a protective effect. The circular chamfer is relatively smooth, making it not easy to damage the groove when the nut is loosened or tightened.

[0023] Furthermore, a support ring is provided between the tool body and the limiting member, and a plurality of strip-shaped grooves are provided on the support ring.

[0024] The support ring is located between the tool body and the limiting member, and a plurality of strip-shaped grooves are provided on its surface, increasing the contact area. When rotating the nut for fastening, a greater frictional force can be generated, which helps to prevent the nut from loosening.

[0025] Furthermore, a bearing is provided at one end of the tool shank, and the bearing is located above the tool body.

[0026] During the woodworking cutting process, the tool body rotates at a high speed to cut the wood. Without the support of the bearing, the friction between the tool body and the tool shank will cause energy loss, heat generation, and rapid wear. The bearing can significantly reduce this friction and extend the service life of the tool.

[0027] The beneficial effects of this application are as follows:

[0028] 1. By adopting the above-mentioned woodworking cutting tool and setting the installation component, the woodworking cutting tool of this application can more effectively fix the tool body on the tool shank, reduce the loosening phenomenon, and improve the stability and safety during the cutting process;

[0029] 2. This application still retains the detachable design of the tool body. When the blade is worn and needs to be replaced or maintained, the user can easily remove the tool body from the tool shank, perform the necessary operations and then reinstall it. It is both convenient and fast. And due to the improvement of the fixing effect, the woodworking cutting tool can maintain a more stable posture during the cutting process, reducing the cutting error caused by vibration or loosening, thereby improving the cutting accuracy and the quality of the workpiece;

[0030] 3. In this application, when the nut is tightened, the nut applies pressure to the elastic member, and the elastic member is compressed so that the end surfaces of the elastic member in contact with the limiting member are fitted together and clamp the tool shank, thereby increasing the pre-tightening force between the nut and the threaded section of the tool shank. When the tool shank and the nut are subjected to strong vibrations and irregular strong force fluctuations, they are not likely to loosen or fall off, thus extending the service life.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally of the same type, and the number of objects is not limited. For example, the first object can be one or multiple. In addition, "and / or" in the specification and claims means at least one of the connected objects, and the character " / " generally means that the associated objects before and after are in an "or" relationship.

[0037] Next, the woodworking cutting tool provided by the embodiments of the present application will be described in detail in conjunction with the accompanying drawings, through specific embodiments and their application scenarios.

[0038] Embodiment 1:

[0039] AsFigures 1 to 3 As shown, an embodiment of the present application provides a woodworking cutting tool, including:

[0040] A tool handle 100;

[0041] A tool body 200, detachably arranged on the tool handle 100, and a blade 210 is arranged on the tool body 200;

[0042] An installation component 300, arranged on the tool handle 100;

[0043] Among them, the tool body 200 is arranged on the tool handle 100 through the installation component 300.

[0044] In some implementation manners of the embodiment of the present application, as Figure 1 shown, by adopting the above woodworking cutting tool and setting the installation component 300, the woodworking cutting tool of the present application can more effectively fix the tool body 200 on the tool handle 100, reduce the loosening phenomenon, and improve the stability and safety during the cutting process. Although the fixing effect is strengthened, the present application still retains the detachable design of the tool body 200. When the blade 210 is worn and needs to be replaced or maintained, the user can easily remove the tool body 200 from the tool handle 100, perform the necessary operations and then reinstall it, which is convenient and fast. Due to the improvement of the fixing effect, the woodworking cutting tool can maintain a more stable posture during the cutting process, reduce the cutting error caused by vibration or loosening, and thus improve the cutting accuracy and the quality of the workpiece.

[0045] Further, a bearing 110 is arranged at one end of the tool handle 100, and the bearing 110 is located above the tool body 200.

[0046] During the woodworking cutting process, the tool body 200 rotates at a high speed and cuts the wood. Without the support of the bearing 110, the friction between the tool body 200 and the tool handle 100 will cause energy loss, heat generation and rapid wear. The bearing 110 can significantly reduce this friction and extend the service life of the tool.

[0047] Embodiment 2:

[0048] An embodiment of the present application provides a woodworking cutting tool. In addition to including the above technical features, the woodworking cutting tool of the embodiment of the present application further includes the following technical features.

[0049] As Figures 1 to 3 shown, the installation component 300 includes:

[0050] A threaded section 310, arranged on the tool handle 100;

[0051] A nut 320, arranged on the tool handle 100 and adapted to the threaded section 310, and an extension ring 321 extending outward is provided at one end of the nut 320;

[0052] A limiting member 330 is disposed at the bottom of the extension ring 321 and located between the nut 320 and the tool body 200, and a limiting port 331 adapted to the extension ring 321 is provided at one end thereof;

[0053] Wherein, the limiting port 331 is annular, and an elastic member 340 is further provided between the nut 320 and the limiting member 330.

[0054] In the embodiment of the present application, the threaded section 310 is disposed on the tool handle 100, providing a threaded connection basis for the nut 320. By rotating the nut 320, the tool body 200 can be accurately installed and fastened along the threaded section 310. One end of the nut 320 is provided with an outwardly extending extension ring 321, which increases the surface area of the nut 320 and also provides a platform for subsequent installation. The extension ring 321, as a part of the nut 320, provides a position for the installation and fixation of the limiting member 330 with its outwardly extending structure. The limiting member 330 is disposed at the bottom of the extension ring 321 and is adapted to the extension ring 321 through the limiting port 331 at one end thereof. The limiting port 331 is annular and can be tightly sleeved on the extension ring 321. The elastic member 340 is disposed between the nut 320 and the limiting member 330, playing a role of buffering and shock absorption. During the cutting process, the elastic member 340 can absorb part of the vibration and impact force, reducing the damage to the tool body 200 and the tool handle 100. At the same time, the presence of the elastic member 340 can also allow the nut 320 to undergo a small displacement when subjected to an external force to a certain extent, thereby reducing the stress concentration caused by rigid connection.

[0055] In the present application, when the nut 320 is tightened, the nut 320 applies pressure to the elastic member 340, and the elastic member 340 is compressed, so that the end faces of the elastic member 340 in contact with the limiting member 330 are fitted together and clamp the tool handle 100, thereby increasing the pre-tightening force of the nut 320 and the threaded section 310 of the tool handle 100. When the tool handle 100 and the nut 320 are subjected to strong vibrations and irregular strong force fluctuations, they are not likely to loosen and fall off, extending the service life.

[0059] In the embodiment of the present application, the protective pipe fitting 332 functions to protect the elastic member 340, preventing the inner wall of the elastic member 340 from directly contacting the threaded section 310, protecting the elastic member 340 from thread wear, thus effectively avoiding jamming of the elastic member 340 and also preventing displacement of the elastic member 340 within the limiting member 330.

[0060] Furthermore, a circular chamfer 341 is provided at one end of the elastic member 340 in contact with the protective pipe fitting 332. The other end of the elastic member 340 is in contact with the inner wall of the limiting member 330. A groove 333 is provided inside the limiting member 330. The groove 333 is adapted to the elastic member 340 and the groove 333 is an arc-shaped groove 333.

[0061] The provision of the circular chamfer 341 and the arc-shaped groove 333 makes it easier for the two to fit together. The arc-shaped structure has the function of automatically adjusting the position, keeping the nut 320 and the tool shank 100 always on the same axis. In addition, it also has a protective effect. The circular chamfer 341 is relatively smooth, making it not easy to damage the groove when the nut 32 is loosened or tightened.
