Description

Technical Field

[0001] This invention relates to the field of metal product processing equipment technology, specifically a cutting device for metal product processing. Background Technology

[0002] With the increasing demand for diversified metal product processing, especially in applications such as on-site processing, customized manufacturing, and high-strength material cutting, higher requirements are placed on the processing efficiency, multi-functionality, and adaptability of processing equipment. Traditional metal cutting equipment mostly adopts a structure of fixed tooling + a single saw blade or milling head, which has limited functions, cumbersome switching, and is difficult to meet the multi-angle and multi-process processing needs of complex components.

[0003] In existing technologies, a common metal processing equipment typically includes a fixed frame, a spindle assembly, and a workpiece clamping structure. A drive motor rotates the spindle to achieve high-speed cutting with a saw blade or milling cutter head. Traditional multi-functional cutting tables achieve different processing functions by changing different tool assemblies. However, this structure requires manual disassembly and assembly during tool changes, lacks an automated coordination mechanism, has low switching efficiency, cannot achieve rapid linkage between operating modes, and has a relatively complex overall structure, occupies a large area, and is not conducive to on-site operation and maintenance.

[0004] In addition, some equipment attempts to adjust the blade angle by adding electric adjustment arms, variable angle mounting brackets, etc. Although the angle-adjustable cutting platform can tilt the saw blade angle within a certain range, the overall structure still relies on manual pre-adjustment and lacks precise transmission structure support, resulting in poor processing consistency and insufficient structural rigidity, making it unsuitable for complex or high-precision industrial scenarios.

[0005] Furthermore, in traditional equipment with reciprocating sawing function, the reciprocating motion of the saw blade is often achieved through mechanical structures such as eccentric wheels and linkage mechanisms. Such mechanisms suffer from problems such as large structural wear, poor vibration accuracy, and low power transmission efficiency, which limit their application in high-frequency vibration cutting.

[0006] In summary, existing metal product processing equipment generally suffers from the following shortcomings: Low efficiency of function switching: Most devices only support a single sawing or milling cutting function, lack a unified coordination and control mechanism, and switching requires manual operation or disassembly, making it difficult to achieve automatic switching. The power transmission path is not adjustable: the traditional structure cannot adjust the main shaft transmission link according to different working conditions, and there is a lack of effective isolation and coupling control between functional modules, resulting in high energy consumption and complex structure; Reciprocating cutting structures are inefficient: Existing high-frequency sawing structures mostly rely on traditional mechanical cams or linkages, resulting in short structural lifespans, uncontrollable vibration amplitudes, and low response frequencies, making it difficult to meet the demands for high-efficiency and high-precision sawing.

[0007] Therefore, there is an urgent need for a new type of metal product cutting device that is compact, has automatic switching capability, fast high-frequency cutting response, and is suitable for various processing scenarios, in order to solve the problems of cumbersome process switching, poor processing accuracy, and low functional integration in the existing technology. Summary of the Invention

[0008] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0009] Therefore, the technical solution adopted by the present invention is as follows: a cutting device for processing metal products, comprising: a frame, a sawing assembly, a transducer assembly, and a transmission box fixedly installed on the top of the frame; the surface of the frame is provided with a multi-axis tooling assembly for tooling positioning of metal products; the sawing assembly is fixedly installed on the bottom surface of the transmission box, and the transducer assembly is fixedly installed on the surface of the sawing assembly; a first drive motor and a second drive motor are fixedly installed on the surface of the transmission box.

[0010] The sawing assembly includes: a ball bearing, a ball cap, and an output shaft rotatably mounted inside the ball bearing; an outer bushing connected to the output end of the second drive motor and an inner shaft connected to the output end of the first drive motor are sequentially rotatably sleeved on the inner side of the ball bearing; a toothed ring is fixed on one side of the output shaft and rotatably mounted on the surface of the ball bearing; one end of the output shaft passes through the surface of the ball cap and is detachably connected to a saw blade; a transmission tooth that meshes with the end of the inner shaft is fixedly sleeved on the surface of the output shaft, and an output tooth is slidably sleeved thereon; a clutch cylinder for driving the output tooth to slide is provided on the surface of the output shaft.

[0011] The transducer assembly includes: a transmission box, a fixed base, a fixed gear plate, and a movable gear plate; an input shaft and a rotating head shaft are rotatably mounted inside the transmission box; a key shaft is connected to the end of the input shaft, and the key shaft is used to drive the movable gear plate to rotate; the movable gear plate is sleeved on the surface of the rotating head shaft; the fixed base is fixed inside the transmission box, and a guide rail is slidably mounted on the surface of the fixed base; a guide bead is embedded at the top of the rotating head shaft and abuts against the bottom surface of the guide rail; the surface of the movable gear plate is provided with vibration guide teeth that fit against the bottom surface of the fixed gear plate.

[0012] In a preferred embodiment, the present invention can be further configured such that: the output ends of the first drive motor and the second drive motor are respectively connected to the ends of the inner shaft and the outer bushing via a pulley set located inside the transmission box; the outer bushing is rotatably sleeved on the inner side of the ball head bearing, the inner shaft is rotatably sleeved on the inner side of the outer bushing, and both ends are provided with bevel gear structures.

[0013] In another preferred embodiment, the present invention can be further configured as follows: the ball head bearing surface is provided with a hemispherical cover, the rotating ball cover is a hemispherical shell structure, the output shaft is arranged obliquely and located on the axis of the rotating ball cover, the transmission teeth and the output teeth are both bevel gear structures, and the gear ring meshes with the end of the outer bushing.

[0014] In another preferred embodiment, the present invention can be further configured such that: the surface of the rotary shaft is provided with a key that matches the inner side of the moving gear disk; when the vibration guide tooth is in contact with the bottom surface of the fixed plate tooth, the key on the surface of the rotary shaft disengages from the inner side of the moving gear disk, thereby realizing the transmission separation between the rotary shaft and the moving gear disk.

[0015] Specifically, the engagement structure between the keyed teeth on the surface of the rotary head shaft and the moving gear disc allows the rotary head shaft to move upwards when it comes into contact with the surface of the metal product and generates a reaction force, thereby disengaging from the keyed teeth and releasing the transmission connection. In milling cutter mode, the engagement of the guide rails and guide balls allows the keyed teeth on the rotary head shaft to re-engage with the inner side of the moving gear disc, achieving a rotational connection between the two. When the keyed teeth are disengaged, the moving gear disc, through a vibration guide tooth structure that fits against the surface of the fixed gear, converts the rotational motion into high-frequency vibration of the rotary head shaft for reciprocating sawing operations.

[0016] In another preferred embodiment, the present invention can be further configured such that: the opposing surfaces of the vibration guide teeth and the fixed plate teeth are provided with a plurality of radially arranged tooth structures, the cross-section of the teeth being an isosceles triangle; the surface of the vibration guide teeth is provided with a spring, one end of the spring being sleeved on the surface of the rotating head shaft, and the other end being rotatably connected to the bottom surface of the fixed plate teeth.

[0017] Specifically, when the vibration guide teeth and the fixed plate teeth are in contact, the rotation of the moving toothed disc drives the teeth on the vibration guide teeth to mesh with the teeth on the fixed plate, thereby converting the rotational motion into axial vibration and achieving a high-frequency energy conversion effect for reciprocating sawing operations.

[0018] In another preferred embodiment, the present invention can be further configured such that: the bottom surface of the guide rail is provided with a ball-and-socket groove structure for sliding against and against the guide ball at the top of the rotating head shaft.

[0019] Specifically, when the guide bead is located in the ball socket groove, the rotary head shaft can move upward during the cutting operation, so that the vibrating guide tooth and the fixed plate tooth surface can be in contact; when the guide bead leaves the ball socket groove, the rotary head shaft and the moving tooth disk move downward under the action of gravity, so that the vibrating guide tooth and the fixed plate tooth surface can be in contact, thereby the moving tooth disk drives the rotary head shaft to rotate for milling cutter cutting operation.

[0020] In another preferred embodiment, the present invention can be further configured such that: the bottom end of the rotary head shaft is provided with a chuck for mounting a milling cutter head or a saw blade; the surface of the key shaft rod is provided with helically arranged gear teeth; and the moving gear disk is a helical gear structure.

[0021] In another preferred embodiment, the present invention can be further configured such that: the clutch cylinder is an electric push rod structure, sleeved on the surface of the output shaft, for driving the output teeth to slide axially to achieve engagement or disengagement functions.

[0022] The beneficial effects achieved by this invention are as follows: 1. By setting up multi-axis tooling components for precise positioning and adjustment of metal components, and combining the rotatable structure between the ball bearing and the ball cover, the direction of the cutting components can be switched. With the detachable design of the saw blade and the milling cutter head, this device can flexibly switch between three working modes: high-speed sawing, reciprocating sawing, and milling, significantly improving the applicability of the equipment and the flexibility of on-site processing.

[0023] 2. In this invention, by setting a clutch cylinder to control the axial sliding of the output gear, the output power of the inner shaft rod can be selectively transmitted to the input shaft or bypass the transducer assembly to directly drive the output shaft rod, thereby realizing the structural switching of the power transmission path, effectively simplifying the multi-mode drive mechanism, reducing the complexity of the mechanical system, and improving the overall structural integration.

[0024] 3. In this invention, through the meshing structure between the moving toothed disc, the fixed toothed disc, and the rotating head shaft within the transducer assembly, combined with the tooth guiding design of the vibration guide teeth, the rotational motion can be converted into high-frequency axial vibration in the reciprocating sawing mode, thereby achieving the high-frequency reciprocating cutting effect of the saw blade; while in the milling cutter cutting mode, the vibration coupling can be decoupled, achieving stable high-speed rotation of the milling cutter head, thereby improving the multi-functional processing effect and actual cutting efficiency of the device, and adapting to the precision processing needs of different metal products.

[0027] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of a cutting apparatus for metal product processing provided by the present invention.

[0030] Combination Figures 1-8 As shown, the present invention provides a cutting device for processing metal products, comprising: a frame 100, a sawing assembly 200, a transducer assembly 300, and a transmission box 120 fixedly installed on the top of the frame 100. A multi-axis tooling assembly 110 is provided on the surface of the frame 100 for positioning and clamping metal products. A first drive motor 121 and a second drive motor 122 are fixedly installed on the surface of the transmission box 120 to provide the power source required for the operation of the device.

[0031] The sawing assembly 200 is disposed on the bottom surface of the transmission box 120, and includes a ball bearing 210, a ball cover 220, and an output shaft 230 rotatably mounted inside the ball bearing 210. An outer bushing 212 and an inner shaft 211 are sequentially rotatably sleeved around the outer periphery of the output shaft 230. The outer bushing 212 is connected to the output end of the second drive motor 122, and the inner shaft 211 is connected to the output end of the first drive motor 121, thereby enabling multiple motion modes through power switching.

[0032] A gear ring 221 is fixedly mounted on one side of the output shaft 230 and is rotatably mounted on the surface of the ball bearing 210. The other end passes through the surface of the ball cover 220 and is detachably connected to a saw blade 400. A transmission tooth 231 that meshes with the end of the inner shaft 211 is fixedly sleeved on the surface of the output shaft 230 to realize power transmission. An output tooth 233 is also slidably sleeved on the outer side of the output shaft 230, which is driven and adjusted by a clutch cylinder 232 set on the outer surface of the output shaft 230 to realize power engagement or disengagement.

[0033] The transducer assembly 300 is fixedly installed on the surface of the sawing assembly 200, and its structure includes: a transmission box 310, a fixed base 320, a fixed tooth 330, and a moving toothed disc 340. An input shaft 311 and a rotating head shaft 312 are rotatably installed inside the transmission box 310. A key shaft rod 313 is connected to the end of the input shaft 311. The key shaft rod 313 can mesh with the surface of the moving toothed disc 340 to drive the rotating head shaft 312 to rotate or vibrate.

[0034] The movable gear disc 340 is sleeved on the surface of the rotary head shaft 312, which is used to mount saw blades or milling cutter heads to achieve specific cutting functions. The fixed base 320 is fixed inside the transmission box 310, and a guide rail 321 is slidably mounted on its surface. The bottom surface of the guide rail 321 has a ball-and-socket groove, which slides against the guide ball 322 mounted on the top of the rotary head shaft 312 to facilitate position adjustment and working mode switching of the rotary head shaft 312. The lower surface of the movable gear disc 340 is provided with vibration guide teeth 341, which are used to fit against the bottom surface of the fixed gear disc 330 to form a vibration coupling structure.

[0035] Furthermore, such as Figures 2 to 6 As shown, in a preferred embodiment of the present invention, the output ends of the first drive motor 121 and the second drive motor 122 are respectively connected to the inner shaft rod 211 and the outer shaft sleeve 212 via a pulley set provided inside the transmission box 120, thereby realizing dual-path power output; wherein, the outer shaft sleeve 212 is rotatably mounted inside the ball head bearing 210, and the inner shaft rod 211 is sleeved inside the outer shaft sleeve 212, and both ends adopt a bevel gear structure to achieve stable meshing.

[0036] In sawing mode, the ball head bearing 210 has a hemispherical cover structure on its surface, and the rotating ball cover 220 is a hemispherical shell, so that the output shaft 230 is arranged obliquely along the axis. Both the transmission gear 231 and the output gear 233 adopt a bevel gear structure, and the gear ring 221 meshes with the end of the outer bushing 212, thereby realizing the switching power transmission of the output shaft 230.

[0037] In reciprocating sawing mode, the rotary shaft 312 has a pluggable key structure on its surface, which matches the inner side of the moving gear disk 340. Through the sliding engagement of the guide plate 321 and the guide ball 322, the rotary shaft 312 can move up and down depending on whether the guide ball 322 is in the ball socket. When the rotary shaft 312 rises to a certain height, its surface key disengages from the moving gear disk 340, thereby enabling the rotary shaft 312 to obtain high-frequency vibration through the vibration guide tooth 341 structure between the moving gear disk 340 and the fixed gear 330 for reciprocating sawing operation.

[0038] The vibrating guide tooth 341 and the fixed plate tooth 330 each have several radially arranged teeth on their opposing surfaces, and the cross-section of each tooth is an isosceles triangle. A spring 342 is sleeved on the surface of the vibrating guide tooth 341, and the other end of the spring 342 is rotatably connected to the bottom surface of the fixed plate tooth 330. The rotation of the moving toothed disc 340 drives the vibrating guide tooth 341 to mesh, thereby converting the rotational motion into longitudinal vibration of the rotating head shaft 312.

[0039] In the milling cutter cutting mode, such as Figure 8 As shown, after the guide bead 322 disengages from the ball socket at the bottom of the guide plate 321, the rotary head shaft 312 and the moving gear disk 340 move downwards under the action of gravity, causing the vibrating guide tooth 341 to engage with the fixed plate tooth 330. At this time, the rotation of the moving gear disk 340 is transmitted to the rotary head shaft 312 through the key shaft rod 313, enabling the rotary head shaft 312 and the milling cutter head connected to its bottom end to rotate at high speed, thereby completing the milling cutting work of the metal component.

[0040] Specifically, such as Figure 8 As shown: Specifically, the engagement and disengagement structure between the key on the surface of the rotary shaft 312 and the moving gear disk 340 allows the rotary shaft 312 to move upwards when it comes into contact with the surface of the metal product and generates a reaction force, thereby disengaging from the key engagement and releasing the transmission connection. When in milling cutter mode, the abutting engagement of the guide plate 321 and the guide ball 322 allows the key on the rotary shaft 312 to re-engage with the inner side of the moving gear disk 340, achieving a rotational connection between the two. In the disengaged state, the moving gear disk 340, through the vibration guide tooth 341 structure that conforms to the surface of the fixed gear 330, converts the rotational motion into high-frequency vibration of the rotary shaft 312 for reciprocating sawing operations.

[0041] Furthermore, when the guide teeth 341 and the fixed teeth 330 are in contact, the rotation of the moving tooth disk 340 drives the teeth on the guide teeth 341 to mesh with the fixed teeth 330, thereby converting the rotational motion into axial vibration and achieving a high-frequency energy conversion effect for reciprocating sawing operations. When the guide bead 322 is located in the ball socket groove, the rotating head shaft 312 can move upward during the cutting operation, allowing the surfaces of the guide teeth 341 and the fixed teeth 330 to come into contact. When the guide bead 322 leaves the ball socket groove, the rotating head shaft 312 and the moving tooth disk 340 move downward under the action of gravity, causing the guide teeth 341 to contact the surfaces of the fixed teeth 330, thereby driving the rotating head shaft 312 to rotate for milling cutter cutting operations.

[0042] like Figure 7 As shown, the bottom end of the rotary shaft 312 is equipped with a chuck structure for mounting milling cutter heads or saw blades, enabling quick replacement of different cutting tools. The key shaft 313 has helically arranged gear teeth on its surface for stable meshing transmission; the moving gear disc 340 adopts a helical gear structure to enhance the meshing angle and optimize torque transmission performance.

[0043] The clutch cylinder 232 is an electric push rod structure, which is sleeved and installed on the surface of the output shaft 230. It can precisely drive the output teeth 233 to slide axially, realizing the engagement or disengagement of the sawing components, and plays a key role in switching operating modes.

[0044] The cutting device provided by this invention, through its multi-mode collaborative switching structural design, can not only realize three working modes: rotary cutting, reciprocating sawing, and milling, but also has efficient power switching and work conversion capabilities. It is suitable for various metal product processing scenarios, significantly improving work efficiency and adaptability.

[0045] Working principle and usage process of this invention: First, the metal component to be processed is fixed on the surface of the multi-axis tooling assembly 110. The position and angle of the metal component are adjusted by the adjustment mechanism of the multi-axis tooling assembly 110 to achieve accurate alignment between the surface to be processed and the sawing assembly 200 or the transducer assembly 300, so as to meet the requirements of different processing technology.

[0046] High-speed sawing mode: The second drive motor 122 is started, which drives the outer bushing 212 to rotate. The end of the outer bushing 212 meshes with the gear ring 221 for transmission, which further drives the ball cover 220 to rotate 90 degrees around the axis on the surface of the ball head bearing 210, thereby turning the transducer 300 to a lateral position and disengaging it from the state of being directly opposite the metal component. Subsequently, the clutch cylinder 232 is activated, driving the output tooth 233 to slide axially along the output shaft 230 and disengaging the output tooth 233 from the input shaft 311. At this time, a suitable saw blade 400 can be installed at the end of the output shaft 230 as needed. Next, the first drive motor 121 is started, and the inner shaft 211 begins to rotate. The inner shaft 211 drives the output shaft 230 to rotate through the transmission gear 231, which in turn drives the saw blade 400 installed at its end to achieve high-speed rotational cutting and complete the cutting operation of the metal component.

[0047] Reciprocating sawing mode: When switching to reciprocating sawing mode, the clutch cylinder 232 drives the output tooth 233 to slide along the output shaft 230 to the engagement position, so that the output tooth 233 and the input shaft 311 can achieve effective transmission. At the same time, by rotating the ball cover 220, the transducer assembly 300 is reset to a vertically downward state, ensuring that its end is vertically connected to the metal component. After the saw blade is clamped and installed at the bottom of the rotating shaft 312, the guide plate 321 is manually moved so that the guide ball 322 enters the ball socket groove set at the bottom of the guide plate 321, thereby triggering the rotating shaft 312 to move upward, which in turn reduces the gap between the vibrating guide tooth 341 and the fixed plate tooth 330, and achieves the tooth surface to fit together, thus completing the switching of working mode. During operation, the first drive motor 121 drives the inner shaft 211 to rotate, and through the meshing structure between the inner shaft 211, the transmission gear 231, the output gear 233 and the input shaft 311, it further transmits the power to the key shaft 313, and the key shaft 313 drives the moving gear disk 340 and the rotating head shaft 312 to rotate as a whole. Meanwhile, due to the special meshing structure between the guide teeth 341 and the fixed teeth 330, a high-frequency reciprocating motion is generated in the vertical direction during the rotation of the moving tooth disk 340, which in turn drives the rotating head shaft 312 and its end saw blade to perform a high-frequency reciprocating sawing operation on the surface of the metal component.

[0048] Milling cutter cutting modes: After the milling cutter head is installed in the chuck at the bottom of the rotary head shaft 312, manually move the guide plate 321 laterally to disengage the guide ball 322 from the ball socket at the bottom of the guide plate 321. At this time, the rotary head shaft 312 moves downward under the action of gravity, which drives the moving gear plate 340 to move down and away from the surface of the fixed gear plate 330, thereby releasing the vibration coupling state between the guide tooth 341 and the fixed gear plate 330 and entering the rotary milling cutter cutting mode. Subsequently, the first drive motor 121 is started, and through the power transmission between the inner shaft rod 211, the transmission gear 231, the output gear 233 and the input shaft 311, the key shaft rod 313 is driven to rotate. The key shaft rod 313 then drives the moving gear disk 340 and the rotating head shaft 312 to rotate, thereby making the milling cutter head rotate at high speed and realizing the milling cutter cutting operation on the surface of the metal component.

[0049] This invention, by setting up a multi-axis tooling assembly 110, a clutch cylinder 232, a ball head bearing 210, and a matching transducer assembly 300, enables the switching of working conditions between the sawing assembly 200 and the transducer assembly 300. It can complete three processing functions—high-speed sawing, reciprocating sawing, and milling cutter cutting—without replacing the entire machine, greatly improving the multifunctionality and working efficiency of the processing equipment, and is suitable for the complex processing needs of various types of metal products.
