[0002] Toy car parts can be divided into multiple categories according to function, material and processing technology, covering transmission, structure, decoration and other purposes. The manufacturing of key bearing and transmission parts such as shafts, transmissions and housings requires high precision cutting processing to achieve core shape molding and performance protection. In the processing link of shaft parts, long shaft blanks have the advantages of convenient storage, efficient transportation and strong batch processing, and have become the mainstream initial blank form in the industry. The short shaft blank formed after accurate cutting is the basis for subsequent turning, milling and grinding, directly determines the assembly adaptability and transmission stability of the final shaft part, and is an indispensable core initial shape in the manufacturing process of shaft parts.

[0003] In the existing processing of shaft toy car parts, long shaft blanks are first cut into multiple short shaft blanks, and then the multiple short shaft blanks are clamped. The processing time of toy car part short shaft blanks is generally small, and frequent clamping of short shaft blanks is required, which seriously prolongs the production rhythm, greatly reduces the processing efficiency, and increases the labor intensity of the operator who needs to repeatedly perform positioning, clamping, disassembly and other repetitive work. SUMMARY

[0004] The present application aims to solve the problem that in the existing processing of shaft toy car parts, long shaft blanks are first cut into multiple short shaft blanks, and then the multiple short shaft blanks are clamped. The processing time of toy car part short shaft blanks is generally small, and frequent clamping of short shaft blanks is required, which seriously prolongs the production rhythm, greatly reduces the processing efficiency, and increases the labor intensity of the operator who needs to repeatedly perform positioning, clamping, disassembly and other repetitive work.

[0006] As a further scheme of the present application: the support piece comprises a mounting table fixedly connected with the base, a hydraulic rod is fixedly connected with the top end of the mounting table, the movable end of the hydraulic rod is fixedly connected with a mounting plate, the linear driver is fixedly arranged on the mounting plate, and a support rod is fixedly connected with the top end of the mounting plate.

[0007] As a further scheme of the present application: the base is provided with a cutting piece for cutting the shaft blank, the mounting frame is provided with a deviation correcting piece for clamping and limiting the cutting end of the long shaft blank, the plug post is in the shape of a mountain, the support rod is in the shape of Y, and the driving shaft is in the shape of T.

[0008] As a further scheme of the present application: the cutting piece comprises an X-axis movement system fixedly connected with the top end of the base, an Y-axis movement system fixedly connected with the movable end of the X-axis movement system, a switching motor fixedly connected with the movable end of the Y-axis movement system, and a cutter disc fixedly connected with the output end of the switching motor.

[0009] As a further scheme of the present application: the driving piece further comprises a rotating motor fixedly connected with the side end of the mounting table, a transmission wheel fixedly connected with the output end of the rotating motor, a transmission belt in transmission connection between the transmission wheel and the driving shaft, a T-shaped groove arranged in the bottom end of the mounting plate, a T-shaped sliding block slidably connected in the T-shaped groove, an outer ring fixedly connected with the bottom end of the sliding block and arranged in the inner wall of the outer ring, a connecting rod fixedly connected with the inner wall of the outer ring, an inner ring fixedly connected with one end of the connecting rod, a rotating groove penetratingly arranged in the side end of the inner ring, a middle group of rectangular straight columns in the mountain-shaped plug post penetrating through the rotating groove and fixedly connected with the support frame, and the support frame is arranged on the inner side of the inner ring, the other two groups of rectangular straight columns in the mountain-shaped plug post abut against the two sides of the inner ring, and a penetration hole one penetrating through the driving shaft end face and used for the long shaft blank.

[0010] As a further embodiment of the present invention: an avoidance groove is provided on the connection side of the clamping arm and the rotating cylinder, one side of the support frame is located in the avoidance groove, a stabilizing plate is fixedly connected to the outside of the linkage rod, and the stabilizing plate abuts against the side of the upper moving groove facing the support member, and the stabilizing plate and the activation rod are at the same horizontal height. As the insert moves, when the clamping force of the clamping arm on the long shaft blank reaches a certain level, the guide block can no longer move in the guide groove. At this time, the activation rod moves synchronously with the insert, releasing the magnetic connection with the magnetic plate. When it moves to the limit position, the end face of the activation rod abuts against the stabilizing plate, generating a reverse thrust, maintaining the clamping force of the clamping arm, and preventing the clamping from loosening during the rotation and cutting of the long shaft blank.

[0011] As a further aspect of the present invention: the clamping arms are arranged in a Y-shaped staggered distribution, and each set of rotating cylinders connected at one end of the two sets of clamping arms has a through hole. Each set of through holes has two sets of guide blocks distributed symmetrically. The guide grooves are arranged in four sets, which are symmetrically distributed on the outer circular surface of the activation rod. The two sets of guide grooves are symmetrically distributed, and the two sets of guide grooves are rotated and mirrored, so that the two sets of clamping arms are synchronously facing each other or opposite to each other. Multiple sets of magnetic blocks are evenly embedded on the adjacent surfaces of the two sets of clamping arms, and the corresponding surfaces of the magnetic blocks on the two sets of clamping arms are opposite poles. When the two sets of clamping arms are joined in an X-shape, the magnetic blocks at the overlapping point generate an attractive force to prevent the two sets of clamping arms from loosening.

[0012] As a further embodiment of the present invention: the correction component includes a mounting plate fixedly connected to the mounting bracket on the side facing the cutting component. The end face of the mounting plate is provided with a through hole two for the long shaft blank to pass through. The through hole two is connected to the through hole one on the end face of the drive shaft, and the inner diameters of the two sets of through holes are the same.

[0013] As a further embodiment of the present invention: a T-shaped mounting groove is provided on the outer circular surface of the mounting plate, and the mounting groove is connected to the through hole penetrating the end face of the mounting plate. Four sets of mounting holes are provided at the T-shaped recess of the T-shaped mounting groove. A T-shaped correction plate is slidably inserted into the T-shaped mounting groove. The bottom end of the correction plate is inserted into the through hole penetrating the end face of the mounting plate, and the part of the correction plate located in the through hole penetrating the end face of the mounting plate has an arc-shaped angle facing the support. A spring is fixedly connected to the bottom end of the four sets of mounting holes, and the top end of the spring is fixedly connected to the bottom end of the T-shaped head of the correction plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, the transmission structure of the driving component, combined with the rotational connection between the T-shaped drive shaft and the mounting bracket, achieves stable and efficient power transmission, ensuring the constant rotation of the long shaft blank. Through the sliding cooperation of the upper moving groove and the linkage rod, it not only adapts to the movement requirements of the clamping component, but also accurately pulls the insertion column to rotate synchronously. Through the adaptation of the inner ring, the rotating groove and the insertion column, and the sliding cooperation of the outer ring, the sliding block and the mounting plate, rotational interference is avoided, improving the coaxiality of the long shaft blank's rotation. Through the through hole one, a stable insertion channel is provided for the long shaft blank, further preventing deviation and jump during rotation, laying a solid foundation for cutting accuracy. 2. In this invention, the linear actuator of the clamping component drives the insertion post to move, and with the sliding structure of the guide block and the spiral guide groove, the clamping arm can automatically open and close without manual intervention. It is suitable for continuous cutting of long shaft blanks, reduces the number of repeated clamping, and greatly improves the operating efficiency. The magnetic plate and the activation rod adsorption, the reverse thrust of the stabilizing plate, and the opposite pole attraction of the magnetic block form a triple lock to prevent the long shaft blank from loosening when it rotates and cuts. The four specially arranged guide grooves cooperate with the guide block to ensure that the clamping arm moves synchronously and the clamping force is uniform, preventing the long shaft blank from deforming. The avoidance groove avoids the interference of the support frame, realizing precise linkage between clamping and resetting, ensuring that the long shaft blank is clamped and released smoothly, and is suitable for the batch processing needs of short shaft blanks in a short time. 3. In this invention, the elastic cooperation between the correction plate and the spring in the correction component enables automatic correction during the insertion of the long shaft blank, compensating for its own straightness deviation. No manual calibration is required, simplifying the operation. The arc-shaped angle design at the bottom of the correction plate guides the long shaft blank to precise positioning while avoiding surface scratches, ensuring the quality of part processing. The symmetrical distribution of the correction plate along the two through holes forms an all-round limiting guide, ensuring that the axis of the long shaft blank is precisely aligned with the rotation center of the cutter head, improving cutting accuracy. The elastic buffer of the spring allows the correction plate to flexibly fit the long shaft blank, adapting to different diameter processing requirements and enhancing the versatility of the device.

The following describes embodiments of the invention based on its overall structure.

[0019] Reference Figure 1 In this embodiment of the invention, a cutting device for manufacturing and processing toy car parts includes: a base 1, a cutting component 2 for cutting a shaft blank on the base 1, a support component 3 for supporting a long shaft blank on the side of the base 1, a clamping component 4 for clamping and pushing the long shaft blank to move on the support component 3, a mounting frame 5 on the base 1, a driving component 6 for driving the clamping component 4 to drive the long shaft blank to rotate on the mounting frame 5, and a correction component 7 for clamping and limiting the cutting end of the long shaft blank on the mounting frame 5. The cutting part 2 includes an X-axis moving system 21 fixedly connected to the top of the base 1. A Y-axis moving system 22 is fixedly connected to the movable end of the X-axis moving system 21. A switching motor 23 is fixedly connected to the movable end of the Y-axis moving system 22. A tool head 24 is fixedly connected to the output end of the switching motor 23. The X-axis moving system 21 and the Y-axis moving system 22 are the core feed mechanisms of the cutting part 2 using existing technology. Essentially, they are transmission components in a lathe that drive the tool to achieve precise movement. The X-axis moving system 21 is arranged along the axial direction of the long shaft blank and can drive the Y-axis moving system 22, the switching motor 23, and the tool head 24 connected to it to move back and forth linearly. This is used to adjust the axial distance between the tool head 24 and the long shaft blank to adapt to the cutting requirements of short shafts of different lengths. The Y-axis moving system 22 is arranged perpendicular to the X-axis direction and can drive the tool head 24 to move left and right linearly, realizing the cutting or retraction action of the tool towards the long shaft blank, and precisely controlling the cutting depth and cutting position. The two work together to allow the tool head 24 to move in multiple directions in the plane, meeting the position adjustment requirements for cutting the long shaft blank and subsequent processing. Support 3 includes a mounting platform 31 fixedly connected to the base 1. A hydraulic rod 32 is fixedly connected to the top of the mounting platform 31, and a mounting plate 33 is fixedly connected to its movable end. A Y-shaped support rod 34 is fixedly connected to the top of the mounting plate 33. The support frame is used to adjust the height of the long shaft blank placed on the support rod 34 so that its axis is in the same straight line as the axis of the through hole 65. Reference Figure 2 as well as Figures 8 to 9The driving component 6 includes a T-shaped drive shaft 61, a rotary motor 62, a transmission wheel 63, a transmission belt 64, a T-slot, a through hole 65, an upper sliding groove 66, a linkage rod 67, a T-shaped sliding block 68, an outer ring 69, a connecting rod 610, an inner ring 611, and a rotating groove 612. The rotary motor 62 is fixedly connected to the side end of the mounting platform 31. The output end of the rotary motor 62 is fixedly connected to the transmission wheel 63. A transmission belt 64 connects the transmission wheel 63 and the T-shaped drive shaft 61. The T-shaped drive shaft 61 passes through the mounting bracket 5 and is rotatably connected to the mounting bracket 5, allowing it to rotate smoothly around the axis of the mounting bracket 5. The end face of the T-shaped drive shaft 61 facing the support component 3 has an upper sliding groove 66, which provides sliding space for the linkage rod 67. A connecting rod 67 is slidably connected within the groove. The movable rod 67 and the linkage rod 67, with one end away from the T-shaped drive shaft 61, are inserted into the mountain-shaped insert 42, which can drive the mountain-shaped insert 42 to move synchronously. The bottom end of the mounting plate 33 has a T-shaped groove, and a T-shaped sliding block 68 is slidably connected in the T-shaped groove. The T-shaped sliding block 68 can slide flexibly along the T-shaped groove. Its bottom end is fixedly connected to an outer ring 69, and the T-shaped sliding block 68 is set in the inner wall of the outer ring 69 to achieve a stable connection with the outer ring 69. A connecting rod 610 is fixedly connected to the inner wall of the outer ring 69, and one end of the connecting rod 610 is fixedly connected to an inner ring 611. The connecting rod 610 connects the outer ring 69 and the inner ring 611 into one unit to ensure structural stability. A rotating groove 612 is opened through the side end of the inner ring 611. The rotating groove 612 provides a lifting mechanism for the rotation of the mountain-shaped insert 42. To provide suitable space, the middle set of rectangular straight columns in the mountain-shaped insert 42 passes through the rotating groove 612 and is fixedly connected to the support frame 43. The support frame 43 is set inside the inner ring 611. The other two sets of rectangular straight columns in the mountain-shaped insert 42 abut against the two sides of the inner ring 611 to form a limiting fit. The end face of the T-shaped drive shaft 61 has a through hole 65 for the long shaft blank to pass through. The through hole 65 is connected to the through hole 72 of the mounting plate 71 and has the same inner diameter, providing a passage for the long shaft blank. When the long shaft blank is firmly clamped by the clamping part 4 and the length extending out of the through hole 72 reaches the preset processing size, the rotating motor 62 is started. The output end of the rotating motor 62 drives the transmission wheel 63 to rotate, and the power is transmitted to the T-shaped drive shaft 61 through the transmission belt 64, so that the T-shaped drive shaft 61... The T-shaped drive shaft 61 rotates smoothly around the mounting bracket 5. When the T-shaped drive shaft 61 rotates, the upper moving groove 66 on its end face rotates synchronously around the axis of the T-shaped drive shaft 61, thereby driving the sliding linkage rod 67 in the groove to rotate together. The linkage rod 67, through the insertion and engagement with the mountain-shaped plug 42, pulls the mountain-shaped plug 42 to rotate synchronously around the axis of the T-shaped drive shaft 61. At this time, the inner ring 611 and the outer ring 69 remain stationary. The mountain-shaped plug 42 slides relative to the rotation groove 612 of the inner ring 611. At the same time, the bottom end of the mountain-shaped plug 42 disengages from the rotation slot at the top of the movable end of the linear actuator 41 to avoid the linear actuator 41 interfering with the rotation action. Finally, the mountain-shaped plug 42 drives the top support frame 43 and the clamping arm 45 to rotate synchronously.The clamped long-axis blank is made to rotate at a constant speed.

[0020] The above scheme is adopted: the transmission combination of rotating motor 62, transmission wheel 63 and transmission belt 64 provides a smooth and efficient power transmission to T-shaped drive shaft 61, ensuring that the long shaft blank obtains a constant rotation speed and ensuring the consistency of cutting. Through the sliding cooperation of upper moving groove 66 and linkage rod 67, it not only provides a suitable space for the movement of clamping part 4, but also accurately pulls the mountain-shaped insert 42 to rotate synchronously during rotation, realizing the precise transmission of power. Through the coordinated design of T-slot, T-shaped sliding block 68, outer ring 69, connecting rod 610 and inner ring 611, a stable limiting support structure is formed to avoid component interference during rotation and effectively improve the coaxiality of the long shaft blank's rotation. Through hole one 65 provides a stable through-hole channel for the long shaft blank. With the concentric design of through hole two 72, it further prevents the long shaft blank from deviating or jumping during rotation, laying a solid foundation for cutting accuracy.

[0021] Reference Figures 3 to 7The clamping component 4 includes a linear actuator 41, a U-shaped insert 42, a support frame 43, a rotating cylinder 44, a clamping arm 45, a clearance groove 46, a stabilizing plate 47, a magnetic plate 48, an activation rod 49, a guide groove 410, a guide block 411, and a magnetic block 412. The linear actuator 41 is fixedly attached to the top of the mounting plate 33. The movable end of the linear actuator 41 is rotatably inserted into the U-shaped insert 42, enabling the movement and rotation of the U-shaped insert 42. The support frame 43 is fixedly attached to the top of the U-shaped insert 42, providing a mounting carrier for the rotating cylinder 44. The rotating cylinder 44 is housed within the frame, and a clamping arm 45 is fixedly attached to the side end of the rotating cylinder 44. Two sets of clamping arms 45 are arranged in a Y-shape and staggered for clamping long shaft blanks. One end of the linkage rod 67 passes through the mountain-shaped insert 42 and is fixedly connected to a magnetic plate 48. An activation rod 49 is magnetically attracted to one end of the magnetic plate 48. The activation rod 49 passes through the rotating cylinder 44 and can be attracted to or separated from the magnetic plate 48. A guide block 411 is fixedly connected to the inner side of the rotating cylinder 44. Two sets of guide blocks 411 are symmetrically distributed within the through hole of each set of rotating cylinders 44. Four sets of spiral guide grooves 410 are formed on the outer surface of the activation rod 49. The four sets of guide grooves 410 are symmetrically distributed, with two symmetrical sets being rotationally symmetrical and adjacent sets being rotationally mirror images. The guide blocks 411 and guide grooves 410 are slidably inserted to drive the rotation of the rotating cylinder 44. A clearance groove 46 is formed on the connection side of the clamping arm 45 and the rotating cylinder 44 to support... One side of frame 43 is located within the clearance groove 46 to avoid motion interference. A stabilizing plate 47 is fixedly connected to the outside of linkage rod 67. The stabilizing plate 47 abuts against the side of upper moving groove 66 facing support member 3 and is at the same horizontal height as activation rod 49. Multiple sets of magnetic blocks 412 are evenly embedded on adjacent surfaces of the two sets of clamping arms 45, with corresponding surfaces having opposite poles. After the height of the long shaft blank is calibrated and inserted into the preset position, the linear actuator 41 is activated. Its movable end pushes the mountain-shaped insert 42 to move towards the mounting frame 5, causing support frame 43 and rotating cylinder 44 to move synchronously. At this time, linkage rod 67 attracts activation rod 49 through magnetic plate 48. Linkage rod 67 remains stationary due to upper moving groove 66, activation rod 49 remains fixed, and rotating cylinder... When the guide block 411 moves along the guide groove 410, it drives the clamping arm 45 to rotate synchronously in opposite directions to clamp the long shaft blank. When the clamping force reaches the preset threshold, the guide block 411 cannot move. The activation rod 49 moves with the mountain-shaped insert 42 and releases the adsorption with the magnetic plate 48 until it comes into contact with the stabilizing plate 47 to generate a reverse thrust. The magnetic block 412 is reinforced by opposite polarity adsorption. After the cutting is completed, the linear driver 41 is reset in the reverse direction. The mountain-shaped insert 42 drives the support frame 43, the rotating cylinder 44 and the activation rod 49 to move synchronously. The activation rod 49 contacts the magnetic plate 48 to restore adsorption and fix it. The rotating cylinder 44 continues to move so that the guide block 411 slides in the reverse direction along the guide groove 410. The clamping arm 45 unfolds in the reverse direction to release the long shaft blank.

[0022] The above solution employs a linear actuator 41 to drive the mountain-shaped insert 42 to move. This, combined with the sliding engagement of guide blocks 411 and specially arranged guide grooves 410, enables the clamping arms 45 to automatically rotate in opposite directions without manual intervention, significantly improving clamping and releasing efficiency. A triple-locking structure is formed through the adsorption of the magnetic plate 48 and activation rod 49, the reverse thrust of the stabilizing plate 47, and the opposite-polarity attraction of the magnetic blocks 412. This effectively prevents loosening of the clamping during the long shaft blank's self-rotation cutting, ensuring processing stability. Precise matching of four sets of guide grooves 410 with two sets of guide blocks 411 ensures synchronous movement of the two clamping arms 45, with evenly distributed clamping force, preventing deformation of the long shaft blank due to uneven force. The clearance groove 46 provides movement space for the support frame 43, avoiding motion interference and achieving precise linkage between clamping and resetting actions, ensuring stable clamping and releasing of the long shaft blank and preventing surface damage.

[0023] Reference Figures 10 to 11 The alignment component 7 includes a mounting plate 71, a second through hole 72, a T-shaped mounting groove, a mounting hole, a T-shaped alignment plate 73, and a spring 74. The mounting bracket 5 is fixedly connected to the mounting plate 71 on the side facing the cutting component 2. The end face of the mounting plate 71 has a through hole 72 for the long shaft blank to pass through. The second through hole 72 communicates with the first through hole 65 on the end face of the drive shaft 61, and the inner diameters of the two through holes are the same to ensure smooth passage of the long shaft blank. The outer surface of the mounting plate 71 has a T-shaped mounting groove, which connects to the mounting bracket 5. The through holes on the end face of the mounting plate 71 are interconnected, providing installation and sliding space for the T-shaped correction plate 73. Four sets of mounting holes are provided at the T-shaped recess of the T-shaped mounting groove, evenly distributed around the through hole 72. The T-shaped correction plate 73 is slidably inserted into the T-shaped mounting groove. The bottom end of the T-shaped correction plate 73 is inserted into the through hole on the end face of the mounting plate 71 for contact with the surface of the long shaft blank to achieve correction. The portion of the T-shaped correction plate 73 located in the through hole of the mounting plate 71 leans towards the support member 3. The long shaft blank has rounded corners to avoid scratching it. Springs 74 are fixedly connected to the bottom of each of the four sets of mounting holes. The top of the springs 74 is fixedly connected to the bottom of the T-shaped head of the T-shaped straightening plate 73, providing elastic support for the T-shaped straightening plate 73. After the long shaft blank is height-calibrated by the hydraulic rod 32, one end of the long shaft blank is manually pushed towards the cutting part 2, allowing it to pass sequentially through the through hole 65 of the drive shaft 61 and the through hole 72 of the mounting plate 71. During the insertion process, the surface of the long shaft blank is in contact with the bottom of the T-shaped straightening plate 73. The arc-shaped contact squeezes the T-shaped correction plate 73 to slide upward along the T-shaped mounting groove. The spring 74 is compressed and generates a reverse elastic force, pushing the T-shaped correction plate 73 to always fit against the surface of the long shaft blank. The four sets of T-shaped correction plates 73 form an all-round constraint under the elastic action of the spring 74. The arc-shaped contact guides the long shaft blank to move precisely along the axial direction, effectively compensating for the straightness deviation of the long shaft blank itself, ensuring that the axis of the cutting end of the long shaft blank is precisely aligned with the rotation center of the cutter head 24, and providing positional guarantee for subsequent cutting processing.

[0024] The above solution achieves automatic correction during the long shaft blank insertion process through the elastic cooperation of four sets of T-shaped correction plates 73 and springs 74, eliminating the need for manual calibration, effectively simplifying the operation process and improving processing preparation efficiency. The arc-shaped corner design at the bottom of the T-shaped correction plates 73 guides the long shaft blank's movement while avoiding hard scratches on its surface, ensuring the surface quality of the machined parts. The four sets of T-shaped correction plates 73 are symmetrically distributed circumferentially along the second through hole 72, forming an all-round limiting and guiding structure to ensure precise alignment between the long shaft blank's axis and the rotation center of the cutter head 24, significantly improving the length accuracy and end face flatness of the short shaft blank. The elastic buffering effect of the springs 74 allows the T-shaped correction plates 73 to flexibly fit against the long shaft blank, which can adapt to the processing needs of long shaft blanks with different diameters and avoid deformation of the long shaft blank due to rigid contact, enhancing the versatility and adaptability of the device.

[0025] The working principle of this invention is as follows: In use, the long shaft blank to be processed is first placed stably on the top of the Y-shaped support rod 34 of the support member 3, ensuring that the axis of the long shaft blank is approximately parallel to the direction of the first through hole 65 to avoid initial misalignment. Then, the hydraulic rod 32 of the support member 3 is activated, driving the mounting plate 33 to slowly rise and fall. The height of the long shaft blank is calibrated using auxiliary measuring tools until the axis of the long shaft blank is completely collinear with the first through hole 65 and the second through hole 72. After calibration, the hydraulic rod 32 is locked, keeping the mounting plate 33 in a fixed position. Simultaneously, one end of the long shaft blank rests against the support frame 43. Then, one end of the long shaft blank is manually pushed, allowing it to pass sequentially through the first through hole 65 of the drive shaft 61 and the second through hole 72 of the mounting plate 71. During the insertion process, the four sets of correction plates 7 of the correction member 7... 3. Under the elastic action of spring 74, the long shaft blank automatically conforms to the surface of the long shaft blank. The arc angle at the bottom of the correction plate 73 guides the long shaft blank to move precisely along the axial direction, effectively compensating for the straightness deviation of the long shaft blank itself, and ensuring that the axis of the cutting end is aligned with the rotation center of the cutter head 24. Then, the linear driver 41 of the clamping part 4 is activated, and its movable end pushes the mountain-shaped insert 42 to move smoothly to one side of the mounting frame 5. The support frame 43 at the top of the insert 42 and the rotating cylinder 44 inside the frame move synchronously. At this time, the linkage rod 67 attracts the activation rod 49 through the magnetic plate 48, and the linkage rod 67 is restricted by the upper moving groove 66 and cannot move. The activation rod 49 remains stationary. As the rotating cylinder 44 moves, the guide block 411 on its inner side moves along the spiral guide groove 4 on the outer circle surface of the activation rod 49. 10. Sliding, under the trajectory constraint of the guide groove 410, the rotating cylinder 44 drives the side clamping arms 45 to rotate synchronously towards each other, gradually approaching the surface of the long shaft blank. When the clamping arm 45 contacts the surface of the long shaft blank and generates an initial clamping force, the linear actuator 41 continues to advance, and the clamping force gradually increases. When the clamping force reaches the preset threshold, the guide block 411 cannot continue to slide in the guide groove 410 due to the resistance of the long shaft blank. At this time, the activation rod 49 moves synchronously towards the mounting bracket 5 with the insertion post 42. After the magnetic attraction force with the magnetic plate 48 exceeds the critical value, the attraction is released until the end face of the activation rod 49 is tightly abutted against the stabilizing plate 47 on the outside of the linkage rod 67, generating a reverse thrust to firmly lock the position of the clamping arm 45. At the same time, the magnetic blocks 412 on the two sets of clamping arms 45 are due to The opposing poles generate an adsorption force, providing double protection to prevent the long shaft blank from loosening during subsequent rotation. During this process, the insert 42 pushes the support frame 43, causing the long shaft blank to move towards one end of the cutter head 24. Once the length of the long shaft blank extending beyond the second through hole 72 reaches the preset machining dimension, the movement stops and the position of the long shaft blank is maintained. Then, the rotation motor 62 of the drive component 6 is started, and the motor output drives the transmission wheel 63 to rotate. The power is transmitted to the T-shaped drive shaft 61 through the transmission belt 64. The drive shaft 61 rotates smoothly around the mounting bracket 5. When the drive shaft 61 rotates, the upper moving groove 66 on its end face rotates synchronously around the axis of the drive shaft 61, thereby driving the sliding linkage rod 67 in the groove to rotate together. Since the end of the linkage rod 67 away from the drive shaft 61 is inserted into the insert 42,This causes the insert 42 to rotate synchronously around the axis of the drive shaft 61. It should be noted that during rotation, the inner ring 611 and outer ring 69 remain stationary. The insert 42 slides relative to the rotation groove 612 of the inner ring 611. Simultaneously, the bottom end of the insert 42 disengages from the rotation slot at the top of the movable end of the linear actuator 41, preventing the linear actuator 41 from interfering with the rotation of the insert 42. Finally, the insert 42 drives the top support frame 43 and clamping arm 45 to rotate synchronously, causing the firmly clamped long shaft blank to rotate at a constant speed. During rotation, stability is confirmed by observing the runout of the long shaft blank's end face to ensure no significant shaking. Finally, the switching motor 23 of the cutting part 2 is activated, driving the cutter head 24 to rotate. Cutting is performed according to the processing requirements by switching motor 23. After changing to the appropriate cutting tool, the X-axis movement system 21 is activated, driving the Y-axis movement system 22, the switching motor 23, and the cutter head 24 to move precisely along the axis of the long shaft blank, adjusting to the preset cutting start position. Then, the Y-axis movement system 22 is activated, driving the cutter head 24 to slowly cut into the cutting end of the long shaft blank. During the cutting process, the long shaft blank continues to rotate at a constant speed under the drive of the clamping member 4. The cutter head 24 completes the single cutting of the short shaft blank along the preset trajectory. When the single cutting process is completed, the cutter head 24 retracts and stops rotating. After the long shaft blank stops rotating, the linear driver 41 of the clamping member 4 starts the reverse reset program. Its movable end drives the mountain-shaped insert 42 to move smoothly away from the mounting bracket 5 and closer to the support member 3. At this time, the top of the insert 42 is fixed. The support frame 43, the rotating cylinder 44 inside the support frame 43, and the activation rod 49 penetrating the rotating cylinder 44 all move synchronously in the opposite direction with the insertion post 42. The rotating cylinder 44 and the activation rod 49 remain relatively stationary with no relative displacement. As the reset movement continues, the end of the activation rod 49 away from the stabilizing plate 47 gradually approaches the magnetic plate 48. After their end faces contact, the magnetic adsorption connection is quickly restored. Since the magnetic plate 48 is fixedly connected to the linkage rod 67, and the linkage rod 67 is slidably connected in the upper moving groove 66, it cannot move synchronously with the insertion post 42. The activation rod 49 stops moving under the constraint of the magnetic adsorption force and remains fixed in its current position. Meanwhile, the insertion post 42 continues to move in the opposite direction under the drive of the linear actuator 41, causing the support frame 43 and the rotating cylinder 44 to continuously move towards the magnetic plate 48. As plate 48 approaches, the rotating cylinder 44 and the activation rod 49 move relative to each other. The guide block 411 inside the rotating cylinder 44 moves with the rotating cylinder 44 and slides in the opposite direction along the spiral guide groove 410 on the outer surface of the activation rod 49. Under the precise constraint of the reverse trajectory of the guide groove 410, the rotating cylinder 44 drives the clamping arm 45 at the side to rotate in the opposite direction, opposite to the closing action during clamping. The two sets of clamping arms 45, which are Y-shaped and staggered, gradually unfold in the direction away from the long shaft blank. During this process, the clearance groove 46 on the side where the clamping arm 45 connects to the rotating cylinder 44 adapts to the displacement synchronously with the rotation of the clamping arm 45, always providing sufficient space for the support frame 43 to move, avoiding interference from the support frame 43 to the reverse rotation of the clamping arm 45. At the same time,The opposing polarity attraction of the magnetic blocks 412 on the adjacent surfaces of the two sets of clamping arms 45 gradually weakens and eventually disappears completely as the clamping arms 45 separate, no longer resisting the release action. When the linear actuator 41 returns to its initial position, the clamping arms 45 completely separate from the surface of the long shaft blank, the clamping force is completely released, and the long shaft blank remains in its current position under the support of the Y-shaped support rod 34, preparing for subsequent feeding and re-clamping processing; through the transmission structure of the drive component 6, in conjunction with the rotational connection between the T-shaped drive shaft 61 and the mounting bracket 5, a smooth and efficient power transmission is achieved, ensuring the constant rotation of the long shaft blank. The sliding engagement of the sliding groove 66 and the linkage rod 67 not only adapts to the movement requirements of the clamping member 4, but also precisely pulls the insert 42 to rotate synchronously. Through the adaptation of the inner ring 611, the rotating groove 612, and the insert 42, and the sliding engagement of the outer ring 69, the sliding block 68, and the mounting plate 33, rotational interference is avoided, improving the coaxiality of the long shaft blank's rotation. The through hole 65 provides a stable insertion channel for the long shaft blank, further preventing deviation and jump during rotation, thus laying a solid foundation for cutting accuracy. The linear actuator 41 in the clamping member 4 drives the insert 42 to move, in conjunction with the guide block 411 and the spiral guide groove 410. The sliding structure enables automatic opening and closing of the clamping arm 45 without manual intervention, improving operational efficiency. A triple locking mechanism is formed through the attraction of the magnetic plate 48 and activation rod 49, the reverse thrust of the stabilizing plate 47, and the opposite pole attraction of the magnetic block 412, preventing loosening during the long shaft blank's rotation and cutting. Four specially arranged guide grooves 410, in conjunction with guide blocks 411, ensure synchronized movement of the clamping arm 45 and even distribution of clamping force, preventing deformation of the long shaft blank. The avoidance groove 46 avoids interference from the support frame 43, achieving precise linkage between clamping and resetting, ensuring smooth clamping and release of the long shaft blank. The correction plate in the correction component 7 further contributes to this. The elastic cooperation between the guide plate 73 and spring 74 enables automatic correction during the insertion of the long shaft blank, compensating for its own straightness deviation. This eliminates the need for manual calibration, simplifying operation. The arc-shaped design at the bottom of the guide plate 73 guides the long shaft blank precisely while preventing surface scratches, ensuring part machining quality. The symmetrical distribution of the guide plates 73 along the second through hole 72 forms an all-around limiting guide, ensuring precise alignment between the long shaft blank's axis and the rotation center of the cutter head 24, improving cutting accuracy. The elastic buffer of spring 74 allows the guide plates 73 to flexibly conform to the long shaft blank, adapting to different diameter machining requirements and enhancing the device's versatility.
