Technical Field

[0001] The utility model relates to the technical field of machining tools, in particular to a blade mounting structure, a bevel forming tool and a bevel forming device. Background Art

[0002] During the butt joint of pipe fittings or columnar-structured components, it is necessary to first process the ends of the components to form grooves or bevels for welding.

[0003] During the machining of pipe fittings, generally a bevel tool is used to cut the ends of the pipe fittings. The manufacture of high-pressure large boilers not only puts forward higher requirements for the materials and wall thicknesses of pipes, but also puts forward stricter technical operation specifications for the prefabrication before pipe welding. In order to improve the production efficiency and quality of boiler manufacturing, the requirements for the shape and dimensional accuracy of the bevel before pipe welding are higher than those for the welding of general medium and low pipes.

[0004] In the related art, during the machining of the ends of pipe fittings by the tool, the pipe fittings are prone to jump, affecting the bevel forming accuracy. Summary of the Utility Model

[0005] The utility model discloses a blade mounting structure, a bevel forming tool and a bevel forming device to solve the technical problem of low machining accuracy of the tool for machining pipe fittings in the related art.

[0006] To solve the above problems, the utility model adopts the following technical solutions:

[0007] In a first aspect, the present application provides a blade mounting structure. The blade mounting structure can be used to mount a machining blade. The blade mounting structure includes a mounting seat and a first locking member. The mounting seat has a first mounting portion and a second mounting portion. The first mounting portion is used to fixedly mount a first blade. The first blade is used to machine the first side of the workpiece to be machined. The second mounting portion is used to movably mount a second blade. The second blade is used to machine the second side of the workpiece to be machined, and the second blade can move relative to the first blade in a direction close to or away from the first blade to adjust the distance between the first blade and the second blade. The first locking member is respectively connected to the second blade and the mounting seat, and the second blade can be fixed to the second mounting portion through the first locking member.

[0008] In some optional solutions, the blade mounting structure further includes a moving seat body. The moving seat body is used to fixedly mount the second blade. The moving seat body is movably arranged on the second mounting portion.

[0009] In a second aspect, the present application provides a bevel forming tool. The bevel forming tool includes the blade mounting structure provided by the present application.

[0010] In some alternative solutions, the groove forming tool further includes a first blade and a second blade. The first blade is installed on the first mounting portion, and the first blade is used to machine the first side in the radial direction of the workpiece to be machined. The second blade is installed on the second mounting portion, and the second blade is used to machine the second side of the workpiece to be machined. When the groove forming tool machines the workpiece to be machined, the directions of the radial acting forces of the first blade and the second blade acting on the workpiece to be machined are opposite.

[0011] In a third aspect, the present application provides a groove forming device.

[0012] In some alternative solutions, it further includes a main shaft and a second locking member. Among them, in the second locking member and the mounting seat of the groove forming device, one is provided with a guiding protrusion, and the other is provided with a guiding groove that slidably cooperates with the guiding protrusion.

[0014] In the blade mounting structure provided by the present application, the first mounting portion fixedly mounts the first blade, the second mounting portion movably mounts the second blade, and the first locking member is used to fix the second blade. In this way, during the machining of the workpiece to be machined, the first side and the second side of the workpiece to be machined can be machined simultaneously, which is beneficial to making the forces on the workpiece to be machined and the blade mounting structure balanced during the machining process, and reducing the jumping of the workpiece to be machined or the blade mounting structure.

Detailed implementation manners

[0038] In order to make the objectives, technical solutions and advantages of the present utility model clearer, the technical solutions of the present utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.

[0039] The terms "first", "second", etc. in the description and claims of this application are used to distinguish similar objects, rather than to describe a specific order or sequence. It should be understood that such data used can be interchanged under appropriate circumstances, so that the embodiments of this application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are usually of the same type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the description and claims means at least one of the connected objects, and the character " / ", generally indicates an "or" relationship between the associated objects before and after.

[0040] The following will Figures 1 to 19 be described in detail the blade mounting structure, the groove forming tool and the groove forming equipment provided by the embodiments of this application through specific embodiments and their application scenarios.

[0041] Referring Figure 3 to Figure 4 and

[0042] In some embodiments of this application, the blade mounting structure includes a mounting base 110 and a first locking member 120. The mounting base 110 has a first mounting portion 111 and a second mounting portion 112. Exemplarily, the first mounting portion 111 and the second mounting portion 112 are basic structural members and can be used to mount the blades for processing.

[0043] Specifically, the first locking member 120 can be switched between a first state and a second state. Exemplarily, when the first locking member 120 is in the first state, the second blade 220 and the second mounting portion 112 can move relative to each other, so that the position of the second blade 220 relative to the second mounting portion 112 is adjustable. When the first locking member 120 is in the second state, the second blade 220 and the second mounting portion 112 are relatively fixed, that is, the second blade 220 is fixedly connected to the second mounting portion 112 through the first locking member 120.

[0044] In some embodiments, the first blade 210 and the second blade 220 are arranged along a first direction, and the second mounting portion 112 has a plurality of mounting positions arranged along the first direction. In this way, the distance between the first blade 210 and the second blade 220 can be adjusted by fixing the second blade 220 at different mounting positions.

[0045] In some embodiments, the second blade 220 is slidably engaged with the second mounting portion 112. In this way, the distance between the second blade 220 and the first blade 210 can be adjusted by sliding the second blade 220, and then the second blade 220 is fixed to the second mounting portion 112 by the first locking member 120.

[0046] In some embodiments, the first locking member 120 can be, but is not limited to, a threaded fastener or a snap member, and the threaded fastener can be, but is not limited to, a screw or a bolt.

[0047] In some embodiments, the first blade 210 mounted on the first mounting portion 111 and the second blade 220 mounted on the second mounting portion 112 can be at the same position for machining the workpiece 10 to be machined, or can be at different positions. Exemplarily, the first blade 210 can be used for machining the end face of the workpiece 10 to be machined. The second blade 220 can be used for machining the outer end face of the workpiece 10 to be machined. The main idea of the blade mounting structure provided in this embodiment is that the acting force can be applied to the first side and the second side of the workpiece 10 to be machined through the first blade 210 and the second blade 220 by using the first mounting portion 111 and the second mounting portion 112, so that the workpiece 10 to be machined is more balanced in force during the machining process, the jitter of the workpiece 10 to be machined during the machining process is reduced, the machining accuracy is improved, and the machining blade is protected.

[0048] In some embodiments, the blade mounting structure can be used for machining workpieces with a rotary structure. A workpiece with a rotary structure means that at least part of the workpiece to be machined is a rotary body structure, and the machining part is a rotary body part. For example, the workpiece to be machined has a columnar or cylindrical structure.

[0049] Exemplarily, during the process of using the blade mounting structure for machining a rotary structure, the first blade 210 and the second blade 220 on the first mounting portion 111 can be arranged on both sides in the diameter direction of the rotary structure to be machined. This is beneficial to improving the stability of the workpiece 10 to be machined during the machining process.

[0050] Referring to Figure 5 and Figure 6 the blade mounting structure further includes a moving seat body 130. The moving seat body 130 is used for fixedly mounting the second blade 220. Exemplarily, the moving seat body 130 has a second blade 220 mounting structure, such as a hole or a groove for mounting the second blade 220.

[0051] Reference Figure 5 As shown in Figure 5 , the moving seat body 130 is movably arranged on the second mounting part 112, so that the moving seat body 130 can move relative to the second mounting part 112, and then drive the second blade 220 to move relative to the second mounting part 112, so as to realize that the second blade 220 is movably arranged on the second mounting part 112.

[0052] Reference Figure 6 As shown in Figure 6 , the first locking member 120 is respectively connected to the mounting seat 110 and the moving seat body 130, and the moving seat body 130 can be fixed to the mounting seat 110 through the first locking member 120.

[0053] In the above embodiment, the moving seat body 130 can be used to realize that the second blade 220 is movably arranged on the second mounting part 112. During the process of replacing the second blade 220, only the second blade 220 needs to be disassembled and replaced, and the position of the moving seat body 130 does not need to be adjusted. In this way, after each replacement of the second blade 220 or the first blade 210, the distance between the first blade 210 and the second blade 220 can be kept unchanged. Furthermore, it is not necessary to calibrate the positions of the first blade 210 and the second blade 220, which can simplify the difficulty of blade replacement. In addition, in order to adapt to workpieces 10 of different sizes, only the position of the moving seat body 130 needs to be adjusted, and it is not necessary to disassemble and assemble the second blade 220, which is beneficial to preventing the second blade 220 from being damaged during the disassembly and assembly process.

[0054] Reference Figure 7 and Figure 8 As shown in Figure 7 and Figure 8 , in some embodiments, the second mounting part 112 has a mounting groove 1121. The moving seat body 130 has a positioning protrusion 131. At least part of the positioning protrusion 131 is located in the mounting groove 1121 and is in sliding fit with the mounting groove 1121. Exemplarily, the width of the positioning protrusion 131 is adapted to the width of the mounting groove 1121. Specifically, the opposite sides of the positioning protrusion 131 respectively abut against the opposite inner wall surfaces in the mounting groove 1121, so that the moving seat body 130 can be limited to slide relative to the mounting seat 110 on a preset track through the mounting groove 1121 and the positioning protrusion 131.

[0055] In some embodiments, the positioning protrusion 131 can be strip-shaped, such as a cuboid structure. In some embodiments, the positioning protrusion 131 can include a plurality of protrusion structures spaced apart along a preset direction. Exemplarily, it can be a plurality of columnar protrusion structures. In this way, it is beneficial to improve the cooperation stability between the moving seat body 130 and the second mounting part 112, and it is beneficial to ensure that the moving seat body 130 moves relative to the second mounting part 112 on a preset track.

[0056] In some alternative implementations, the first blade 210 on the first mounting portion 111 and the second blade 220 on the second mounting portion 112 are located on both sides of the workpiece 10 to be machined in the first direction. The mounting groove 1121 and / or the positioning protrusion 131 can be arranged along the first direction to facilitate the adjustment of the blade mounting structure to adapt to workpieces 10 to be machined with different diameters.

[0057] In some embodiments, as Figure 7 and Figure 8 shown, the second mounting portion 112 has a mounting groove 1121. The mounting groove 1121 includes a notch portion 1122 and a bottom portion 1123 communicating with the notch portion 1122. The width of the notch portion is smaller than the width of the bottom portion 1123. Exemplarily, the mounting groove 1121 can be a T-shaped groove. The first locking member 120 includes a fastening block 121 and a fastener 122. The fastening block 121 is movably arranged on the bottom portion 1123. The fastener 122 penetrates through the moving seat body 130, and the first end of the fastener 122 is in limit cooperation with the moving seat body 130, and the second end of the fastener 122 is in threaded cooperation with the fastening block 121.

[0058] Referring to Figure 9 and Figure 10 , in some embodiments, the moving seat body 130 has a through hole 132, and the fastener 122 can penetrate through the moving seat body 130 along the through hole 132 and be connected to the fastening block 121. Exemplarily, a threaded hole is provided on the fastening block 121, the fastener 122 is a bolt, and the fastener 122 can be connected to the fastening block 121 in threaded cooperation.

[0059] In the above embodiments, the blade mounting structure can realize stepless adjustment of the distance between the first mounting portion 111 and the second mounting portion 112 through the mounting groove 1121 and the first locking member 120, that is, it can be fixed at any position between the maximum distance and the minimum distance to achieve continuous adjustment.

[0060] In some embodiments, the height of the positioning protrusion 131 located in the mounting groove 1121 is less than the depth of the mounting groove 1121. Further, the height of the positioning protrusion 131 located in the mounting groove 1121 is less than the depth of the notch portion 1122, that is, the positioning protrusion 131 does not enter the bottom portion 1123. In this way, it is beneficial to switch the first locking member 120 between the first state and the second state by adjusting the fastener 122, that is, to realize the first locking member 120 fastening the moving seat body 130 or loosening the moving seat body 130, so that the moving seat body 130 can be switched between two states of being fixed to the second mounting portion 112 or being movable relative to the second mounting portion 112.

[0061] The first installation part 111 and the second installation part 112 are distributed at intervals along the first direction, and the first blade 210 installed on the first installation part 111 and the second blade 220 installed on the second installation part 112 respectively process the two radial sides of the workpiece 10 to be processed. Exemplarily, the first blade 210 installed on the first installation part 111 and the second blade 220 installed on the second installation part 112 are located on both sides of the same diameter of the workpiece 10 to be processed. Exemplarily, the contact part of the first blade 210 with the workpiece 10 to be processed is the first contact part. The contact part of the second blade 220 with the workpiece 10 to be processed is the second contact part, and the first contact part and the second contact part are located on the same diameter of the workpiece 10 to be processed. This embodiment is beneficial to improving the stability of the workpiece 10 to be processed during the processing process.

[0062] It should be noted that even if there is a deviation within a preset range between the first contact part and the second contact part and they are not located on the same diameter of the workpiece 10 to be processed, the acting forces of the first blade 210 and the second blade 220 on the workpiece 10 to be processed can still cancel each other out partially. Therefore, it is still beneficial to the force balance of the workpiece 10 to be processed and improve the stability of the workpiece 10 to be processed during the processing process.

[0063] Refer to Figure 4 and Figure 12 As shown in FIG. and FIG., the first installation part 111 has two blade installation positions 1111. Among the two blade installation positions 1111, one is used to install the first blade 210, and the other is used to install the third blade 230. One of the first blade 210 and the third blade 230 is used to process the end face of the workpiece 10 to be processed, and the other is used to process the outer end face of the workpiece 10 to be processed.

[0064] Exemplarily, when the workpiece 10 to be processed is a hollow cylindrical structure (for example: steel pipe), the end face of the workpiece 10 to be processed is the end face perpendicular to the axis direction. The outer end face of the workpiece 10 to be processed is the part of the outer peripheral wall adjacent to one end of the extension direction.

[0065] Exemplarily, when the blade installation structure is used for a pipe beveling device, the end face of the pipe and the outer end face of the pipe can be processed synchronously, which is beneficial to improving the processing accuracy of the pipe bevel.

[0066] In some embodiments, the moving seat body 130 has two blade installation positions 1111. Among the two blade installation positions 1111, one is used to install the second blade 220, and the other is used to install the fourth blade 240. One of the third blade 230 and the fourth blade 240 is used to process the end face of the workpiece 10 to be processed, and the other is used to process the outer end face of the workpiece 10 to be processed.

[0067] Refer to Figure 15 and Figure 16, in some embodiments, both the first blade 210 and the second blade 220 are used to machine the same position of the workpiece 10 to be machined, such as the outer end face of the workpiece 10 to be machined. Both the third blade 230 and the fourth blade 240 are used to machine the same position of the workpiece 10 to be machined, such as the end face of the workpiece 10 to be machined.

[0068] In some embodiments, both the first blade 210 and the second blade 220 are first functional blades, that is, the blade structures and models of the first blade 210 and the second blade 220 are the same.

[0069] Exemplarily, the first functional blade has a first cutting edge. When the first functional blade is installed on the first mounting portion 111, the first end of the first cutting edge machines the workpiece 10 to be machined. When the first functional blade is installed on the second mounting portion 112, the second end of the first cutting edge machines the workpiece to be machined. The first end and the second end of the first cutting edge are opposite ends of the first cutting edge. In some embodiments, the first functional blade is installed on the second mounting portion 112, that is, the first functional blade is installed on the movable seat body 130 and cooperates with the second mounting portion 112 through the movable seat body 130 and the first locking member 120.

[0070] Specifically, in some embodiments, when the first blade 210 installed on the first mounting portion 111 is used for the workpiece 10 to be machined, only a part of the cutting edge is used. For example, only the first end of the cutting edge is used. When the first blade 210 installed on the second mounting portion 112 is used for the workpiece 10 to be machined, only another part of the cutting edge is used. For example, only the second end of the cutting edge is used. Thus, when the wear of the first end of the cutting edge of the first blade 210 reaches a preset value, that is, when the first end of the cutting edge of the first blade 210 becomes blunt, the first blade 210 installed on the first mounting portion 111 and the second blade 220 installed on the second mounting portion 112 can be switched. Therefore, this embodiment is beneficial to improving the utilization rate of the tool and extending the service life of the tool.

[0071] Refer to Figure 16 , in some embodiments, the mounting seat 110 has a third mounting portion 113, and the third mounting portion 113 is used to fixedly install a fifth blade 250, and the fifth blade 250 is used to machine the inner end face of the workpiece 10 to be machined. Exemplarily, when the workpiece 10 to be machined is a pipe fitting, the inner end face may be an area of the inner wall surface of the pipe fitting adjacent to the end of its extending direction.

[0072] In some embodiments, such as Figure 15 and Figure 16As shown, in the case of the blade mounting structure for pipe fitting beveling, the outer end faces on both sides in the diameter direction of the pipe fitting can be machined by the first blade 210 and the second blade 220 to achieve beveling of the outer end faces. The third blade 230 and the fourth blade 240 machine the end face of the pipe fitting to make the end face of the pipe fitting flat. The inner end face bevel of the pipe fitting is achieved by the fifth blade 250. In this way, during the machining process, the forces exerted on the workpiece 10 by the first blade 210 and the second blade 220 act in opposite directions, making the workpiece 10 more balanced in force, which is beneficial to preventing the workpiece 10 from jumping.

[0073] In some embodiments, in the pipe fitting beveling process, the cutting amount of the outer end face is greater than that of the inner end face. Therefore, the forces exerted on the workpiece 10 by the first blade 210 and the second blade 220 are greater than the force exerted on the workpiece 10 by the fifth blade 250. Therefore, the influence of the force of the fifth blade 113 for machining the inner end face bevel on the balance of the workpiece 10 is relatively small. In addition, it is beneficial that the cutting amount of the inner end face bevel is small. During the cutting process, the force exerted on the workpiece 10 by the fifth blade 250 can be overcome by the stiffness of the workpiece 10 itself. Therefore, even if there is only one blade for machining the inner end face bevel, it will not cause the workpiece 10 to have a jitter arc exceeding the preset range.

[0074] In some embodiments of the present application, only the fifth blade 250 on one third mounting portion 113 is used to machine the tubular structure or the cylindrical structure. Not only can the problem of uneven force during the machining process be overcome by the stiffness of the workpiece 10 itself, but also it can be balanced by the first blade 210 and the second blade 220 to weaken or eliminate the problem of uneven force that may occur during the unilateral machining of the inner end face bevel. This is not only beneficial to improving the machining accuracy of the workpiece 10, but also can avoid the synchronous machining of the inner slope by multiple blades, so that the blade mounting structure can be applied to the workpiece 10 with a smaller inner diameter of the tubular or cylindrical structure.

[0075] Referring to Figure 16 and Figure 17 , both the first blade 210 and the second blade 220 are second functional blades, that is, the first blade 210 and the second blade 220 adopt blades of the same structure and model. The second functional blade has a second cutting edge 201. When the second functional blade is installed on the first mounting portion 111, the first end of the second cutting edge 201 machines the workpiece 10. When the second functional blade is installed on the third mounting portion 113, the second end of the second cutting edge 201 machines the workpiece 10. The first end and the second end of the second cutting edge 201 are the two opposite ends of the second cutting edge 201.

[0076] This embodiment is beneficial to improving the utilization rate of the first blade 210 and the second blade 220, beneficial to extending the service life of the first blade 210 and the second blade 220, and reducing the processing cost of the workpiece 10 to be processed.

[0077] In some embodiments, such as Figures 11 to 14 , the third mounting portion 113 and the first mounting portion 111 are located on the same side of the workpiece 10 to be processed in the radial direction. This is beneficial to balancing the acting force of the third mounting portion 113 on the workpiece 10 to be processed through the fifth blade 250 by the first mounting portion 111 and the second mounting portion 112, so as to reduce the runout of the workpiece 10 during the processing and improve the processing accuracy.

[0078] In some embodiments, referring to Figure 1 and Figure 2 , the mounting seat 110 is used for movably connecting with the machine tool. And the mounting seat 110 can move relative to the machine tool in the first direction, and the second blade 220 mounted on the second mounting portion 112 can move relative to the machine tool in the second direction, and the first direction is parallel to the second direction.

[0079] The blade mounting structure provided by the above embodiment can be applied to a machine tool with a fixed mounting position of the workpiece 10 to be processed. Specifically, in the case of processing a workpiece 10 to be processed with a larger or smaller diameter, the position of the mounting seat 110 relative to the machine tool can be adjusted so that the first tool 210 on the first mounting portion 111 can be positioned at a position adapted to the size of the workpiece 10 to be processed, and then the position of the second mounting portion 112 relative to the first mounting portion 111 can be adjusted so that the positions of the first blade 210 and the second blade 220 on the blade mounting structure can be adapted to the size of the workpiece 10 to be processed. Specifically, the workpiece 10 to be processed can be installed first, and then the position of the first mounting portion 111 can be positioned by the workpiece 10 to be processed. Finally, by adjusting the position of the second blade 220 relative to the second mounting portion 112, the positions of the first blade 210 and the second blade 220 on the blade mounting structure can be adapted to the size of the workpiece 10 to be processed. This embodiment can reduce the difficulty of blade position adjustment without the aid of a centering structure. It should be noted that for some forming tools with a centering structure, the centering structure will further limit the size of the workpiece 10 to which it is applicable, that is, the applicable size range of the workpiece 10 to be processed is small.

[0080] Referring to Figure 18, in some embodiments, the mounting base 110 has a strip-shaped mounting hole 114, and the mounting hole 114 extends along the first direction. Exemplarily, the mounting base 110 can be fixed to the machine tool by, but not limited to, threaded fasteners. Optionally, the mounting base 110 can be fixed to the machine tool by bolts or screws. Exemplarily, during the installation process, since the mounting hole 114 is a strip-shaped hole, the threaded fastener can slide relative to the mounting base 110 within the mounting hole 114, thereby realizing the adjustment of the position of the mounting base 110 relative to the machine tool in the first direction to adapt to workpieces 10 of different sizes. In this embodiment, the strip-shaped mounting hole 114 enables the position of the mounting base 110 on the machine tool to be continuously adjusted in the first direction, and thus more workpieces 10 of different sizes can be adapted.

[0081] In some embodiments, the mounting base 110 has four strip-shaped mounting holes 114. Exemplarily, the lengths of the strip-shaped mounting holes 114 on the first side of the mounting base 110 in the second direction are equal, and the lengths of the strip-shaped mounting holes 114 on the second side of the mounting base 110 in the second direction are one large and one small. Exemplarily, the second direction can be perpendicular to the first direction, that is, the second direction is perpendicular to the direction in which the second blade 220 moves relative to the mounting base 110. This is beneficial for adapting more installation methods. For example, 4 or 3 threaded fasteners are arranged in the four strip-shaped mounting holes 114 to fix the mounting base 110 and the machine tool.

[0082] In some embodiments, the longer one of the strip-shaped mounting holes 114 on the second side in the second direction is adjacent to the second mounting portion 112, and there is at least partial overlap in the second direction between the one of the strip-shaped mounting holes 114 on the first side in the second direction adjacent to the first mounting portion 111 and the longer one of the strip-shaped mounting holes 114 on the second side in the second direction. In this way, by adjusting the positions of the threaded fasteners within the strip-shaped mounting holes 114, multiple threaded fasteners can be arranged more evenly around the center of the workpiece 10 to be processed.

[0083] In some alternative embodiments, referring to Figure 1 , Figure 2 and Figure 19 , the mounting base 110 has a guiding structure 115 adapted to the machine tool, and the mounting base 110 can be slidably engaged with the machine tool in the first direction through the guiding structure 115. This is beneficial for improving the reliability of the assembly of the mounting base 110 and the machine tool, and is also beneficial for reducing the stress on the threaded fasteners within the strip-shaped mounting hole 114. Moreover, the guiding structure 115 is beneficial for reducing the difficulty of assembling the mounting base 110 onto the machine tool.

[0084] Exemplarily, the guiding structure 115 can be, but not limited to, a protruding structure or a groove structure provided on the mounting base 110. Specifically, as shown in Figure 11 , Figure 11The guiding protrusion 116 for guiding in the guiding structure 115 is shown. The case where the guiding structure 115 is provided as a groove is not shown in the attached drawings of the present application.

[0085] In some embodiments, the mounting seat 110 can be mounted on the main shaft 300 of the machine tool. In this way, during the machining process, the blade mounting structure can rotate along with the main shaft 300 to achieve circumferential cutting of the workpiece 10 to be machined by the first blade 210 and the second blade 220. Exemplarily, when the axial length of the workpiece 10 to be machined is relatively long, this embodiment is beneficial to reducing the runout of the workpiece 10 to be machined and reducing the tooling difficulty required for machining the workpiece 10 to be machined.

Corresponding to different blade structures, those skilled in the art can know that an installation structure for installing the blade needs to be provided on the first installation portion 111, the moving seat body 130, or the second installation portion 112. Therefore, the embodiments of the present application do not limit the specific structures of the first blade 210 and the second blade 220 and the installation structure adapted to the first blade 210 and the second blade 220.

[0088] In some embodiments, the first blade 210 is used to machine the first side in the radial direction of the workpiece to be machined, and the first blade 210 is mounted on the first installation portion 111. The second blade 220 is used to machine the second side of the workpiece to be machined, and the second blade 220 is mounted on the second installation portion 112. Exemplarily, the second blade 220 can be directly mounted in cooperation with the second installation portion 112, or can be mounted in cooperation with the second installation portion 112 through other components, such as the moving seat body 130.

[0089] In some embodiments, when the bevel forming tool 200 machines the workpiece to be machined, the directions of the radial acting forces of the first blade 210 and the second blade 220 on the workpiece to be machined are opposite. In this way, it is beneficial to improving the stability of the workpiece 10 during the machining process.

[0090] In some examples, the groove forming tool 200 further includes at least one of a third cutting blade 230, a fourth cutting blade 240, and a fifth cutting blade 250. Specifically, the third cutting blade 230, the fourth cutting blade 240, and / or the fifth cutting blade 250 can be disposed at the position for installing the cutting blade in the blade mounting structure 100 provided in the embodiments of the present application according to needs.
