Description

Technical Field

[0001] This invention relates to the field of saw blade processing equipment technology, and specifically to a saw blade milling device. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Currently, the milling and filing equipment for saw blades used in delinting machines in China is relatively backward and lacks automation. Patent CN108971636A discloses a hydraulic vertical feed metal circular saw blade milling machine. The milling machine housing has a milling cutter mounted on the cutting groove front part via a rotating shaft. Inside the milling machine housing, a milling motor is mounted on one side of the milling cutter. The output shaft of the milling motor is rotatably connected to the middle of the milling cutter, thereby realizing automated milling of saw blades and improving the automation level of saw blade milling to a certain extent. However, the inventors found that the equipment described in the above patent can only process one saw blade at a time. When processing multiple saw blades, it is necessary to remove and install the saw blades multiple times, resulting in low work efficiency. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a milling device for saw blades that can process multiple saw blades simultaneously with high working efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] An embodiment of the present invention provides a saw blade milling device, including a support platform disposed on the top of a frame. The support platform is provided with a milling body that can rotate around its own axis. A rotating shaft passes coaxially through the inside of the milling body. The rotating shaft is connected to a first drive mechanism disposed on the support platform. The rotating shaft is connected to a plurality of milling cutter assemblies elastically disposed on the milling body through a transmission mechanism inside the milling body. The milling body corresponds to a saw cylinder disposed on one side of the frame so that the milling cutter assemblies can mill the saw blade fixed to the saw cylinder. The support platform is also provided with a second drive mechanism. The second drive mechanism is connected to a swing mechanism and a saw cylinder rotation mechanism. The swing mechanism is connected to the milling body, and the saw cylinder rotation mechanism is connected to the saw cylinder. The saw cylinder is rotatably disposed on a saw cylinder adjustment mechanism.

[0007] Optionally, the transmission mechanism includes a plurality of first bevel gears fixed on a rotating shaft, the first bevel gears meshing with second bevel gears, and the second bevel gears being connected to a milling cutter assembly.

[0008] Optionally, a saw blade clamping component is provided on the side of the frame near the saw cylinder adjustment mechanism. The saw blade clamping component is provided with multiple slots that match the saw blade for clamping the saw blade. The saw blade clamping component is connected to a first linear motion drive mechanism provided on the frame to achieve movement in the direction toward or away from the saw cylinder.

[0009] Optionally, the first linear motion drive mechanism includes a gear shaft disposed below the support platform, the gear shaft being connected to a first gear, the first gear meshing with a rack, the rack being connected to a saw blade clamping member via a connecting plate, the connecting plate being slidably connected to a guide member fixed to the frame, and a locking member being provided between the connecting plate and the guide member.

[0010] Optionally, the support platform is slidably connected to the top of the frame and the support platform is connected to a second linear motion drive mechanism located at one end of the frame to achieve linear motion along the axis of the milling gear body.

[0011] Optionally, the swing mechanism includes a cam connected to a camshaft, the camshaft connected to a second drive mechanism, the cam in contact with a top wheel, the top wheel hinged to one end of a middle rod, the other end of the middle rod fixed to a sector plate, and the sector plate connected to a milling gear body via a connecting rod.

[0012] Optionally, a counterweight is fixed to the intermediate rod.

[0013] Optionally, the saw barrel rotation mechanism includes a drive shaft, one end of which is connected to a second drive mechanism via a first worm gear transmission mechanism, and the other end of which is connected to the saw barrel via a second worm gear transmission mechanism.

[0014] Optionally, the drive shaft is connected to the intermediate shaft via a first worm gear transmission mechanism, and the intermediate shaft is connected to the second drive mechanism via a chain transmission mechanism.

[0015] Optionally, the saw cylinder adjustment mechanism includes a first bracket located on one side of one end of the frame and a second bracket located on the other side of the frame. Both the first and second brackets are equipped with a third linear motion drive mechanism. The third linear motion drive mechanism is connected to the adjustment plate to realize the movement of the adjustment plate seat toward or away from the frame. The two adjustment plates are rotatably connected to both ends of the saw cylinder, respectively.

[0016] The beneficial effects of this invention are:

[0017] 1. The saw blade milling device of the present invention has a milling body, which is provided with multiple milling cutter assemblies. The milling cutter assemblies are connected to a first drive mechanism via a rotating shaft and a transmission mechanism. The milling body is also connected to a swing mechanism, which is connected to a second drive mechanism. The first drive mechanism can drive the milling cutter assemblies to rotate via the rotating shaft and the transmission mechanism. The swing mechanism can drive the milling body to swing, thereby milling the saw blades on the saw cylinder on one side of the frame. It can realize the simultaneous automatic milling of multiple saw blades. Moreover, the saw cylinder is also connected to the saw cylinder rotation mechanism, which can realize the automatic processing of multiple teeth in the circumferential direction of the saw blade. The whole process does not require manual intervention and can realize the simultaneous automatic milling of multiple saw blades, resulting in high work efficiency.

[0018] 2. The saw blade milling device of the present invention has a saw blade clamping component, which can clamp the saw blade through a slot during the saw blade milling process, preventing the saw blade from shaking during processing, ensuring the quality of milled teeth, and thus ensuring the processing quality of the saw blade.

[0019] 3. The milling device for saw blades of the present invention has a third linear motion mechanism in its adjustment mechanism, which can adjust the relative position of the milling cutter and the saw blade, thereby ensuring that the milling cutter is in the required position relative to the saw blade and guaranteeing machining accuracy.

[0020] 4. The saw blade milling device of the present invention has a support table slidably connected to the frame and connected to the second linear motion drive mechanism, which can drive the support table to move, thereby adjusting the relative position of the milling cutter and the saw blade to ensure machining accuracy.

[0021] 5. In the saw blade milling device of the present invention, since the milling cutter assembly is elastically arranged inside the milling tooth body, it can float. Therefore, when the milling cutter mills the saw blade, the milling cutter will not affect the rotation of the saw cylinder. After the milling cutter is separated from the saw blade, it can automatically reset. Thus, the rotation of the saw cylinder and the swing of the milling tooth body can share a set of second drive mechanisms, reducing equipment investment. Attached Figure Description

[0032] Example 1

[0033] This embodiment provides a saw blade milling device, such as... Figures 1-3 As shown, it includes a frame 1, which is a frame structure welded from multiple horizontal square steel bars and vertical steel bars. The frame serves as a load-bearing mechanism for other components.

[0034] The upper surface of the frame 1 is provided with a support platform 2. In this embodiment, the two sides of the support platform 2 along the length direction are defined as the left side and the right side, and the two sides of the support platform 2 along the width direction are defined as the front side and the rear side.

[0035] A milling gear body 3 is provided on the front side of the support platform 2. The milling gear body 3 includes a cylindrical structure 3-1. The bottom of the cylindrical structure 3-1 is provided with a solid cuboid structure 3-2, whose axis is set along the length direction of the support platform 2.

[0036] To facilitate the inspection and replacement of internal components of the milling gear body 3, the milling gear body 3 is composed of an upper part and a lower part that are detachably fixed by bolts and nuts.

[0037] Both ends of the milling gear body 3 are fixed with sleeves by flanges. The sleeves are rotatably connected to the sleeve seat 4. The sleeve seat 4 is fixed to the end of the upper surface of the frame, so the milling gear body 3 can rotate around its own axis.

[0038] In this embodiment, the sleeve seat 4 is also composed of a base and a cover that are detachably connected.

[0039] The cover also has an oil filling hole for adding lubricating oil.

[0040] The sleeve is provided with a bushing inside, through which a rotating shaft 5 passes. The rotating shaft 5 is coaxially arranged with the milling gear body 3, and both ends of the rotating shaft 5 pass through the milling gear body 3. The rotating shaft 5 is rotatably connected to the sleeve through the bushing.

[0041] One end of the rotating shaft 5 is connected to the first drive mechanism, which is fixed to the left end of the support platform.

[0042] In this embodiment, the first drive mechanism adopts a first motor 6. The first motor 6 is fixed to the left end of the support platform 2 through a motor base. The output shaft of the first motor 6 is connected to the left end of the rotating shaft 5 through a belt transmission mechanism 7, which can drive the rotating shaft to rotate around its own axis.

[0043] The cylindrical part of the milling body 3 has a solid cuboid structure at the bottom center, and the bottom surface of the solid cuboid structure has multiple rectangular grooves.

[0044] The bottom surface of the rectangular groove is provided with a tool channel that communicates with the internal space of the milling gear body. A milling cutter assembly is provided in the tool channel. The cutter shaft is rotatably connected to the solid cuboid structure through the channel. In this embodiment, the milling cutter assembly consists of a cutter shaft 8 and a milling cutter 9. The milling cutter 9 is fixed at the end of the cutter shaft 8 that extends to the outside of the cuboid structure. The axis of the milling cutter 9 is perpendicular to the axis of the rotating shaft 5.

[0045] like Figure 4 As shown, in this embodiment, a fixing block 10 is embedded inside the rectangular groove, and the fixing block 10 is fixed to the groove surface of the rectangular groove. The upper surface of the fixing block is attached to one end of the first spring 11 through a pad, and the other end of the first spring 11 is attached to the boss provided on the cutter shaft 8. The first spring 11 is sleeved on the outer periphery of the cutter shaft. A guide block 12 is provided at the top of the cutter shaft 8. The guide block 12 is embedded in the sliding groove of the bevel gear shaft 14 fixed to the bevel gear 13. The fixing block 10 is also provided with a horizontal channel, and a second spring 15 is inserted into the horizontal channel. The cutter shaft 8 is provided with second springs 15 on both sides. One end of the second spring 15 is attached to the cutter shaft 8, and the other end is attached to the other end of the spring 15. One end is attached to the baffle 16 fixed to the side of the solid cuboid structure. In this embodiment, the baffle on the outside of the cuboid structure is a single rectangular plate connected to the cuboid structure by bolts. The baffle on the other side is made of multiple U-shaped plates. Each second spring corresponds to one U-shaped plate. The U-shaped plates are fixedly connected to the cuboid structure. The first spring 11 and the second spring 15 realize the floating of the cutter shaft 8 in the up-down and back-forward directions, thereby realizing the elastic connection between the cutter shaft 8 and the milling gear body. The cutter shaft 8 is connected to the milling cutter after passing through the fixing block 10. The diameter of the channel in the fixing block 10 for the cutter shaft 8 to pass through is larger than the diameter of the cutter shaft 8.

[0046] The top ends of multiple cutter shafts 8 are connected to the rotating shaft through a transmission mechanism. The rotation of the rotating shaft can drive the cutter shaft to rotate around its own axis through the transmission mechanism.

[0047] The transmission mechanism employs a bevel gear transmission mechanism. Each cutter shaft corresponds to a first bevel gear and a second bevel gear 13. The first bevel gear is fixed to the rotating shaft 5 via a key connection. The first bevel gear meshes with the second bevel gear 13. The second bevel gear 13 is provided with a bevel gear shaft 14. The top end of the cutter shaft 8 is inserted into the bevel gear shaft 14. The bevel gear shaft 14 is rotatably connected to the milling gear body 3 via a tool channel. The cutter shaft 8 is slidably connected to the bevel gear shaft 14 via a guide block 12 fixed at its end, allowing the cutter shaft 8 to float along the axial direction of the bevel gear 13. Through the first spring 11, the fixing block 10, and the boss of the cutter shaft 8, the cutter shaft 8 can be positioned inside the milling gear body 3. The first spring 11 enables the cutter shaft 8 to float along its own axial direction. Since the diameter of the cutter shaft is smaller than the diameter of the tool channel, the second spring 15 enables the cutter shaft 8 to float in the front-back direction.

[0048] A positioning sleeve is provided between adjacent first bevel gears on the rotating shaft 5, and the first bevel gear is positioned by the positioning sleeve.

[0049] One end of the rotating shaft 5 is connected to the belt drive mechanism, and the other end is equipped with a handle, which is used to fine-tune the position of the milling cutter assembly.

[0050] A second drive mechanism is provided at the right side of the center of the support platform 2. The second drive mechanism is connected to the swing mechanism, which is connected to the milling gear body and can drive the milling gear body to rotate around its own axis.

[0051] In this embodiment, the second drive mechanism includes a second motor 16, the housing of the second motor 16 is fixed to the housing of the reducer 17, the housing of the reducer 17 is fixed on the support platform 2, the output shaft of the second motor 16 is connected to the reducer 17, the end of the output shaft of the reducer 17 is rotatably connected to the bearing seat, and the bearing seat is fixed on the support platform to support the output shaft of the reducer.

[0052] like Figure 5 As shown, the swing mechanism includes a cam 18, which is fixedly connected to the output shaft of a reducer 17. The reducer 17 can drive the cam 18 to rotate. A top wheel 19 is provided above the cam, and the wheel surface of the top wheel 19 contacts the wheel surface of the cam 18. The top wheel 19 is rotatably connected to one end of the intermediate rod 20. Specifically, the end of the intermediate rod 20 is provided with a slot, and the top wheel 19 is inserted into the slot. A bolt passes through the slot, and the bolt is fixed to the intermediate rod 20 by a nut. The bolt also passes through the top wheel, and the top wheel 19 is rotatably connected to the intermediate rod 20 by the bolt.

[0053] The other end of the intermediate rod 20 is fixedly connected to a sector block 21. Specifically, the other end of the intermediate rod 20 is also provided with a slot, the sector block 21 is inserted into the slot, and the end of the intermediate rod 20 is locked and fixedly connected to the center position of the sector block by bolts and nuts.

[0054] A connecting rod 22 is provided on one side end face of the sector block 21 along the circumferential direction. The connecting rod 22 is a bent rod, including a first rod part and a second rod part. The first rod part is fixed to the sector block 21, and the end of the second rod part passes through the solid cuboid structure of the milled tooth body and is fixed by bolts.

[0055] The second motor drives the cam to rotate via a reducer. The cam can drive the milling cutter body to rotate around its own axis via the intermediate rod, sector block and connecting rod, thereby realizing the swing of multiple milling cutter assemblies.

[0056] In this embodiment, in order to adjust the relative angle between the intermediate rod and the sector block, an arc groove is provided on the sector block, through which a bolt passes. The bolt is fixed to the intermediate rod by a nut. After the angle is adjusted, the bolt and nut are tightened and fixed.

[0057] To ensure that the top wheel always fits in contact with the cam, a counterweight is fixed on the intermediate rod.

[0058] The second drive mechanism is also connected to the saw cylinder rotation mechanism, which can drive the saw cylinder to rotate around its own axis through the saw cylinder rotation mechanism.

[0059] The saw cylinder is located on the front side of the milling tooth body and corresponds to the milling tooth body. It is used to fix multiple saw blades. When the milling tooth body 3 rotates around its own axis, the milling cutter assembly swings, and the milling cutter can mill the saw blades on the saw cylinder.

[0060] like Figure 5 As shown, the saw barrel rotation mechanism includes an intermediate shaft 23, which is rotatably connected to two bearing seats. The bearing seats are fixed on the support platform 2, and the intermediate shaft is supported by the bearing seats.

[0061] One end of the intermediate shaft 23 is connected to the output shaft of the reducer 17 via a chain drive mechanism 24, and the other end is connected to one end of the drive shaft 26 via a first worm gear drive mechanism 25. The other end of the drive shaft 26 is connected to the right end of the saw cylinder via a second worm gear drive mechanism 27. The power of the output shaft of the reducer 17 can be transmitted to the intermediate shaft 23 via the chain drive mechanism 24. The intermediate shaft 23 transmits the power to the saw cylinder via the first worm gear drive mechanism 25 and the second worm gear drive mechanism 27, thereby driving the saw cylinder to rotate around its own axis.

[0062] The saw cylinder is connected to a saw cylinder adjustment mechanism located on the front side of the frame. The saw cylinder adjustment mechanism includes a first bracket 28 located at one end of the saw cylinder and a second bracket 29 located at the other end of the saw cylinder.

[0063] The first support 28 and the second support 29 have the same structure, both including two side channel steels. The bottom of the two side channel steels is fixed to the upper surface of the square steel at the bottom of the frame, and a top channel steel is provided between the tops of the two side channel steels.

[0064] Lifting mechanisms 30 are provided between the two side channel steels of the first support 28 and the second support 29 to facilitate the adjustment of the height of the saw cylinder. After the saw cylinder is adjusted to the required height, the lifting mechanism can be locked.

[0065] The following explanation uses the lifting mechanism of the first support 29 as an example:

[0066] The lifting mechanism 30 can be any existing lifting mechanism, such as a scissor lift mechanism, a hydraulic lift mechanism, or an electric lift mechanism. In this embodiment, the lifting mechanism 30 includes a first lifting plate and a second lifting plate arranged opposite to each other. The bottom ends of the first lifting plate and the second lifting plate are both hinged to the bottom of the first support through a hinge shaft. The top end of the first lifting plate is hinged to the bottom end of the third lifting plate through a hinge shaft. The top end of the third lifting plate is hinged to the top channel steel through a hinge shaft. The top end of the second lifting plate is hinged to the bottom end of the fourth lifting plate through a hinge shaft. The top end of the fourth lifting plate is hinged to the top channel steel through a hinge shaft.

[0067] Locking rods 31 pass through the hinge shafts between the first and third lifting plates and between the second and fourth lifting plates. The locking rods 31 are threaded rods, which are threadedly connected to the two hinge shafts, thereby locking and fixing the entire lifting mechanism. The locking rods pass through elongated holes in the side channel steel.

[0068] A third linear motion drive mechanism is provided on the top channel steel. The third linear motion drive mechanism is connected to the adjustment plate 32 and can drive the adjustment plate 32 to move towards or away from the frame.

[0069] In this embodiment, the third linear motion drive mechanism includes a first housing fixed on the top channel steel of the first bracket and a second housing fixed on the top channel steel of the second bracket.

[0070] A drive shaft 43 passes between the first and second housings. A handle is provided at the left end of the drive shaft 43. The portion of the drive shaft 43 located inside the first and second housings is provided with a worm gear section. The worm gear section meshes with a worm wheel, which is connected to a lead screw 34. The lead screw 44 inside the first housing is rotatably connected to the first housing, and the lead screw 34 inside the second housing is rotatably connected to the second housing. Both the lead screw 44 inside the first and second housings are threadedly connected to a lead screw slider. The lead screw slider is slidably connected to the housing and is fixedly connected to the adjusting plate 32. By rotating the drive shaft with the handle, the lead screws inside the two housings can be rotated using the worm gear transmission mechanism, which in turn drives the adjusting plate 32 to move toward or away from the frame via the lead screw slider.

[0071] The adjusting plate 32 is provided with a bearing seat. The bearing seat of the first bracket 28 is rotatably connected to one end of the saw cylinder, and the bearing seat of the second bracket 29 is rotatably connected to the other end of the saw cylinder, thereby enabling the saw cylinder to rotate around its own axis under the action of the saw cylinder rotation mechanism.

[0072] In this embodiment, the distance between the saw barrel and the milling tooth body can be adjusted by the saw barrel adjustment mechanism, thereby precisely controlling the milling depth of the milling cutter.

[0073] The relative positions of the milling cutter 9 and the saw cylinder in the front-to-back direction are adjusted by the third linear motion drive mechanism, and the relative positions of the milling cutter 9 and the saw cylinder in the left-to-right direction are adjusted by the second linear motion drive mechanism.

[0074] In this embodiment, the second linear motion drive mechanism includes an electric push rod 33 located at the right end of the frame. The fixed part of the electric push rod 33 is fixedly connected to the frame 1, and its telescopic part is connected to the right end of the support platform 2. The support platform is slidably connected to the top surface of the frame, thereby realizing the movement of the support platform in the left and right directions under the action of the electric push rod, realizing the adjustment of the left and right positions of the milling cutter and the saw cylinder, and thus realizing the adjustment of the left and right positions of the milling cutter and the saw blade.

[0075] In this embodiment, multiple limiting plates 34 are provided on the rear side of the frame, and limiting grooves are provided on the limiting plates 34. Correspondingly, multiple limiting members passing through the limiting grooves are provided on the rear end face of the support platform 2. The limiting members are slidably connected to the limiting plates through the limiting grooves, thereby realizing the guidance of the movement of the support platform. The limiting members are bolts, and the bolts are threadedly connected to the support platform. A proximity switch is provided in the limiting groove. The proximity switch cooperates with the bolt. When the set proximity switch detects that the bolt is close, it controls the electric push rod to stop working.

[0076] When the proximity switch at the far end detects the limit switch, it controls the electric push rod to stop working and return to its original position.

[0077] With this setup, because the spacing between the saw blades on the saw cylinder is very small, all the milling cutters cannot mill all the saw blades at once. By using an electric push rod, the relative position of the milling cutter and the saw cylinder can be changed, thereby enabling the milling of all the saw blades.

[0078] In this embodiment, the position of the saw cylinder and the position of the support platform are pre-adjusted according to the milling requirements of the saw blade. The vertical position of the saw cylinder is locked by a locking rod, and the front-to-back position is locked by the self-locking action of the worm gear transmission mechanism. After the position of the support platform is adjusted, the milling of the saw blade can be carried out.

[0079] like Figure 6 As shown, during the milling process of the saw blade, it will shake under the action of the milling cutter, which will affect the processing quality. Therefore, in this embodiment, a saw blade clamping member 35 is provided on the front side of the frame, that is, the side close to the saw cylinder. The saw blade clamping member 35 is arranged along the length direction of the support platform and the frame. The saw blade clamping member is provided with multiple slots, which are used to clamp the saw blade and prevent the saw blade from shaking too much.

[0080] In order to adjust the position of the saw blade clamp 35, the saw blade clamp 35 is connected to the first linear motion drive mechanism, which can drive the saw blade clamp to make linear motion toward or away from the saw cylinder.

[0081] like Figures 7-8 As shown, in this embodiment, the first linear motion drive mechanism includes two guide members 36. The guide members 36 are arranged in the front-back direction. The two ends of the guide members 36 are fixed to the frame 1. The middle part of the guide member is provided with a protrusion. Correspondingly, the support platform is provided with a rectangular opening so that the movement of the support platform 2 is not affected by the guide members 36. A connecting plate 37 is slidably connected in the protrusion of the guide member 36. The connecting plate 37 is fixedly connected to the saw blade clamping member 35. A locking member is provided between the connecting plate 37 and the guide member. The locking member adopts a locking bolt 38. The locking bolt 38 is threadedly connected to the guide member 36, which can press and fix the connecting plate 37, thereby locking the position of the saw blade clamping member.

[0082] The bottom surface of the connecting plate 38 is provided with a rack 39, which meshes with a gear 40. The gear 40 is fixedly connected to a gear shaft 41. The gear shaft 41 is arranged along the length of the frame 1 and is rotatably connected to the frame 1. A handle is provided at the right end of the gear shaft to facilitate the rotation of the gear shaft by the operator.

[0083] The bottom surfaces of both guide members 36 are provided with bearing seats, which are rotatably connected to the gear shaft 41 to support the gear shaft.

[0084] In this embodiment, both the first motor and the second motor are connected to the control system. The control system adopts a PLC controller, which is located in the control cabinet 42 on the right side of the frame, and can realize the automated operation of the first motor and the second motor.

[0085] The working method of the saw blade milling device in this embodiment is as follows:

[0086] The position of the saw cylinder is pre-adjusted via a lifting mechanism and a third linear motion drive mechanism to reach the target position. The position of the support platform is adjusted via a second linear motion mechanism to ensure the relative position of the saw blade and the milling cutter meets the processing requirements. The position of the saw blade clamping component is adjusted via a first linear motion mechanism to ensure its position meets the processing needs. Simultaneously, the saw blade clamping component's slot holds the saw blade.

[0087] The first motor is started, which drives the cutter shaft to rotate through the rotating shaft and bevel gear transmission mechanism, thereby driving the milling cutter to rotate. The second motor is started, which drives the saw cylinder to rotate through the reducer, chain transmission mechanism and two worm gear transmission mechanisms. At the same time, the second motor also drives the milling cutter assembly to swing through the cam, intermediate rod and connecting rod. The swing of the milling cutter assembly can mill the teeth of the saw blade on the saw cylinder.

[0088] During the machining of a single tooth by the milling cutter, the rotation of the saw blade is not affected by the milling cutter because the cutter shaft is connected to the milling tooth body through a spring. After the milling cutter disengages from the saw blade, it resets under the action of the spring. The time it takes for the saw blade to rotate one tooth is the same as the time it takes for the milling tooth body to swing once, thus enabling the machining of multiple teeth on the saw blade.

[0089] In this embodiment, since the cutter shaft can float along its own axis, and the guide block at the top of the cutter shaft is slidably connected to the bevel gear shaft through a groove, the floating in this direction will not affect the meshing of the first bevel gear and the second bevel gear. During the machining process, the floating amplitude of the cutter shaft in the front-back direction is very small and will not affect the meshing of the first bevel gear and the second gear.

[0090] The milling device of this embodiment can simultaneously process multiple teeth of multiple saw blades along the circumferential direction, and the saw blades can rotate automatically with the saw cylinder. The entire processing process does not require manual intervention and has high work efficiency.
