Description

Technical Field

[0001] The present application belongs to the technical field of woodworking tools, and in particular, relates to a woodworking milling cutter. Background Art

[0002] In the process of making wooden furniture, since the edges of the furniture have certain edges and corners, the edges of the wooden furniture need to be milled 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, carpenters generally use manual arc knives to manually plan the edges of furniture. Manual planing has relatively low work efficiency, and the planing effect is not good, which easily leads to inconsistent curvature of the edges.

[0003] The patent with publication number CN214819342U discloses a woodworking milling cutter, which relates to the technical field of woodworking tools, including a handle, a cutter body and a milling blade, the milling blade is arranged on the cutter body, a mounting rod is arranged at one end of the handle, and the cutter body is detachably connected to the mounting rod.

[0004] The above patent fixes the milling blade to the side wall of the corresponding fixing groove by threaded connection of bolts and threaded holes, so that when the milling blade is worn, the tool handle is retained and the tool body and the milling blade can be disassembled and replaced. Although that can ensure replacement, during actual use, there will be problems with thread wear on the tool body, which will make it impossible to tighten the blade with the bolts, and the tool body needs to be replaced, causing unnecessary losses, and improvement is needed. Utility Model Content

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

[0006] The purpose of the present application is to provide a woodworking milling cutter, comprising a cutter body, a milling blade mounted on the cutter body and a bearing, wherein the cutter body is provided with a mounting opening, the milling blade is located in the mounting opening, and further comprising a mounting assembly, which is arranged on the milling blade and is used to mount the milling blade on the cutter body, wherein the mounting assembly comprises:

[0007] A fixing piece is detachably arranged on the cutter body, and a threaded hole is arranged on the fixing piece;

[0008] A fastener having an end provided with threads;

[0009] A first through hole is provided on the milling blade;

[0010] A second through hole is provided on the cutter body and communicated with the threaded hole;

[0011] The fastener passes through the first through hole and the second through hole in sequence and is connected to the threaded hole.

[0012] By using the above-mentioned woodworking milling cutter, by adopting a detachable fixing part, when the threaded hole cannot effectively fix the fastener due to long-term use or wear, the user can only replace the fixing part instead of the entire cutter body, which not only reduces the cost of replacing parts, but also avoids the waste of resources caused by the scrapping of the entire cutter body. When it is necessary to replace the fixing part, the operation is relatively simple and quick, and there is no need to disassemble the entire cutter body, thereby shortening maintenance time and downtime and improving work efficiency. And by replacing the worn fixing part, the stable connection between the milling blade and the cutter body can be maintained, avoiding the reduction of cutting quality or damage to the tool due to loose connection, thereby extending the service life of the overall tool.

[0013] Furthermore, the blade body is provided with a slot adapted to the fixing piece, and the slot and the fixing piece are connected by plugging.

[0014] The plug-in connection between the slot and the fixing makes the installation and removal process faster and simpler. Users can easily fix the fixing on the knife body or remove it from the knife body without using complicated tools or performing cumbersome operations. The plug-in connection is not only fast, but also can provide a stable connection effect. By adopting the slot and plug-in connection method, the structural design of the knife body and the fixing can be simplified, unnecessary parts and connection points can be reduced, the overall structure can be more compact and lightweight, and the manufacturing cost can be reduced.

[0015] Further: the fastener includes an end portion and a rod portion, and the diameter of the rod portion is smaller than the diameters of the first through hole and the second through hole.

[0016] Since the diameter of the rod is smaller than the diameter of the through hole, this means that during the fastening process, there will be no direct metal contact between the fastener and the through hole, which can significantly reduce the wear caused by friction and protect the milling blade, the cutter body and the threaded portion of the fastener. In addition, it avoids direct contact between the thread and the first through hole and the second through hole, and also reduces the risk of thread damage caused by cutting force or vibration. At the same time, although there is a gap between the rod and the through hole, the end of the fastener is firmly connected to the fixing member through the thread, ensuring the stability of the entire connection structure and enhancing the rigidity and reliability of the connection.

[0017] Furthermore, an outer ring is provided on the rod, an inner ring is provided in the second through hole, an elastic member is provided between the inner ring and the outer ring, and a center hole for the rod to pass through is provided in the center of the inner ring, and the diameter of the outer ring is smaller than the diameters of the first through hole and the second through hole.

[0018] Through the deformation of the spring, the elastic force generated between the inner ring and the outer ring provides a stable pre-tightening force for the fastener, which helps to ensure that the milling blade can remain stable after installation and is not easy to loosen. Due to the existence of the spring, even if it is subjected to a large cutting force or vibration during operation, the fastener can absorb part of the impact force through the elastic deformation of the spring, thereby protecting the threaded connection from damage and extending the service life of the fastener and the cutter body. At the same time, although the spring and the inner and outer ring structures are set, it does not increase the difficulty of installation and disassembly. When installing, you only need to pass the fastener through the first through hole and the second through hole, and ensure that the spring is correctly installed between the inner ring and the outer ring. When disassembling, you only need to rotate the fastener in the opposite direction to easily remove it.

[0019] Furthermore, a limiting collar is provided on the rod portion, the limiting collar is located between the outer ring and the end portion, and a limiting groove adapted to the limiting collar is provided on the milling blade, and the limiting groove is plug-connected with the limiting collar.

[0020] The plug-in connection between the limiting collar and the limiting groove provides precise guidance and positioning for the position of the fastener rod on the milling blade, ensuring that the fastener can accurately enter the predetermined position during installation, avoiding installation failure or cutting error caused by position deviation. At the same time, during the cutting process, due to the influence of vibration and cutting force, the fastener may become slightly loose, and the close combination of the limiting collar and the limiting groove can effectively prevent such loosening and maintain the stability of the connection.

[0021] Furthermore, a gasket is provided between the limiting collar and the end portion.

[0022] By setting washers, fasteners can be protected. As an additional support and buffer layer, they can further disperse the stress and vibration generated during the fastening process, enhance the stability of the connection, and help reduce the risk of loosening or damage caused by vibration and stress concentration. At the same time, washers can increase the contact area of ​​fasteners, thereby dispersing the load generated during the fastening process, helping to reduce the pressure on a single contact point and reduce wear or damage caused by excessive local pressure.

[0023] The beneficial effects of this application are:

[0024] 1. By adopting detachable fixings, when the threaded holes cannot effectively fix the fasteners due to long-term use or wear, users can only replace the fixings instead of the entire cutter body, which not only reduces the cost of replacing parts, but also avoids the waste of resources caused by the scrapping of the entire cutter body;

[0025] 2. Since the diameter of the rod is smaller than the diameter of the through hole, this means that during the fastening process, there will be no direct metal contact between the fastener and the through hole, which can significantly reduce the wear caused by friction and protect the milling insert, the cutter body and the threaded portion of the fastener. In addition, it avoids direct contact between the thread and the first through hole and the second through hole, and also reduces the risk of thread damage caused by cutting force or vibration;

[0026] 3. Through the deformation of the spring, the elastic force generated between the inner ring and the outer ring provides a stable preload for the fastener, which helps to ensure that the milling insert can remain stable after installation and is not easy to loosen. Due to the existence of the spring, even if it is subjected to a large cutting force or vibration during operation, the fastener can absorb part of the impact force through the elastic deformation of the spring, thereby protecting the threaded connection from damage and extending the service life of the fastener and the cutter body.

[0034] The woodworking milling cutter provided in the embodiment of the present application is described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0035] Embodiment 1:

[0036] like Figures 1 to 4 As shown, the embodiment of the present application provides a woodworking milling cutter, including a cutter body 100, a milling blade 200 and a bearing 300 mounted on the cutter body 100, the cutter body 100 is provided with a mounting opening 110, the milling blade 200 is located in the mounting opening 110, and also includes a mounting assembly 400, which is arranged on the milling blade 200 and is used to mount the milling blade 200 on the cutter body 100, and the mounting assembly 400 includes:

[0037] A fixing member 410 is detachably disposed on the blade body 100 , and a threaded hole 411 is disposed on the fixing member 410 ;

[0038] A fastener 420, whose end 421 is provided with threads;

[0039] A first through hole 430 is provided on the milling blade 200;

[0040] A second through hole 440 is provided on the blade body 100 and communicates with the threaded hole 411;

[0041] The fastener 420 passes through the first through hole 430 and the second through hole 440 in sequence and is connected to the threaded hole 411 .

[0042] In some implementations of the embodiments of the present application, Figure 1As shown, a woodworking milling cutter as described above is used. By adopting a detachable fixing part 410, when the threaded hole 411 cannot effectively fix the fastener 420 due to long-term use or wear, the user can only replace the fixing part 410 instead of the entire cutter body 100, which not only reduces the cost of replacing parts, but also avoids the waste of resources caused by the scrapping of the entire cutter body 100. When it is necessary to replace the fixing part 410, the operation is relatively simple and quick, and there is no need to disassemble the entire cutter body 100, thereby shortening the maintenance time and downtime and improving work efficiency. And by replacing the worn fixing part 410, the stable connection between the milling blade 200 and the cutter body 100 can be maintained, avoiding the reduction of cutting quality or damage to the cutter due to loose connection, thereby extending the service life of the overall cutter.

[0043] In addition, a slot 412 adapted to the fixing member 410 is provided on the blade body 100 , and the slot 412 and the fixing member 410 are connected by plugging.

[0044] The plug-in connection between the slot 412 and the fixing member 410 makes the installation and removal process faster and simpler. The user can easily fix the fixing member 410 on the blade body 100 or remove it from the blade body 100 without using complicated tools or performing cumbersome operations. The plug-in connection is not only fast but also can provide a stable connection effect. By adopting the slot 412 and the plug-in connection method, the structural design of the blade body 100 and the fixing member 410 can be simplified, unnecessary parts and connection points can be reduced, the overall structure is more compact and lightweight, and the manufacturing cost is reduced.

[0045] Embodiment 2:

[0046] An embodiment of the present application provides a woodworking milling cutter. In addition to the above-mentioned technical features, the woodworking milling cutter of the embodiment of the present application also includes the following technical features.

[0047] like Figure 3 and Figure 4 As shown, the fastener 420 includes an end portion 421 and a stem portion 422 , and a diameter of the stem portion 422 is smaller than a diameter of the first through hole 430 and a diameter of the second through hole 440 .

[0048] In the embodiment of the present application, since the diameter of the rod 422 is smaller than the diameter of the through hole, this means that during the fastening process, no direct metal contact is formed between the fastener 420 and the through hole, which can significantly reduce the wear caused by friction, protect the milling blade 200, the cutter body 100 and the threaded portion of the fastener 420, and avoid direct contact between the thread and the first through hole 430 and the second through hole 440, and reduce the risk of thread damage caused by cutting force or vibration. At the same time, although there is a gap between the rod 422 and the through hole, the end 421 of the fastener 420 is firmly connected to the fixing member 410 through the thread, ensuring the stability of the entire connection structure and enhancing the rigidity and reliability of the connection.

[0049] Moreover, an outer ring 423 is provided on the rod portion 422, an inner ring 424 is provided in the second through hole 440, an elastic member 425 is provided between the inner ring 424 and the outer ring 423, and a center hole for the rod portion 422 to pass through is provided at the center of the inner ring 424, and the diameter of the outer ring 423 is smaller than the diameters of the first through hole 430 and the second through hole 440.

[0050] In some embodiments of the present application, the elastic force generated between the inner ring 424 and the outer ring 423 through the deformation of the spring provides a stable pre-tightening force for the fastener 420, which helps to ensure that the milling blade 200 can remain stable after installation and is not easy to loosen. Due to the presence of the spring, even if it is subjected to a large cutting force or vibration during operation, the fastener 420 can absorb part of the impact force through the elastic deformation of the spring, thereby protecting the threaded connection from damage and extending the service life of the fastener 420 and the cutter body 100. At the same time, although the spring and the inner and outer ring 423 structure are set, it does not increase the difficulty of installation and disassembly. During installation, it is only necessary to pass the fastener 420 through the first through hole 430 and the second through hole 440, and ensure that the spring is correctly installed between the inner ring 424 and the outer ring 423. During disassembly, it is also only necessary to reversely rotate the fastener 420 to easily remove it.

[0054] In the embodiment of the present application, the plug-in connection between the limiting collar 426 and the limiting groove 427 provides accurate guidance and positioning for the position of the rod 422 of the fastener 420 on the milling blade 200, ensuring that the fastener 420 can accurately enter the predetermined position during installation, avoiding installation failure or cutting error caused by position deviation. At the same time, during the cutting process, due to the influence of vibration and cutting force, the fastener 420 may be slightly loose, and the tight combination of the limiting collar 426 and the limiting groove 427 can effectively prevent such loosening and maintain the stability of the connection.

[0055] Embodiment 4:

[0056] An embodiment of the present application provides a woodworking milling cutter. In addition to the above-mentioned technical features, the woodworking milling cutter of the embodiment of the present application also includes the following technical features.

[0057] like Figure 4 As shown, a gasket 450 is further disposed between the limiting collar 426 and the end portion 421 .

[0058] In the embodiment of the present application, by providing the washer 450, the fastener 420 can be protected, and as an additional support and buffer layer, the stress and vibration generated during the fastening process can be further dispersed, the stability of the connection can be enhanced, and the risk of loose connection or damage caused by vibration and stress concentration can be reduced. At the same time, the washer 450 can increase the contact area of ​​the fastener 420, thereby dispersing the load generated during the fastening process, helping to reduce the pressure on a single contact point, and reducing wear or damage caused by excessive local pressure.
