Description

Technical Field

[0001] This application relates to the technical field of lathe machining, and in particular to a workpiece cutting system. Background Technology

[0002] The lathe is a core machine tool that uses a cutting tool to turn workpieces. It is also one of the most widely used pieces of equipment in metal cutting. It can cut the inner and outer surfaces, end faces and spiral surfaces of workpieces and plays an irreplaceable role in the field of mechanical manufacturing.

[0003] In the existing workpiece cutting process, lathes usually use general-purpose fixtures or manual clamping to fix the workpiece. These traditional clamping methods are simple in structure, low in manufacturing cost, and applicable to workpieces of various specifications and shapes, with a wide range of applications.

[0004] However, in actual machining, some workpieces require cutting at multiple different locations. After the cutting head completes the cutting at a certain location, the workpiece must be removed from the fixture, its clamping position adjusted, and then it re-clamped and fixed before cutting can continue at the next location. This repeated disassembly and reassembly not only consumes a lot of manual time, resulting in low overall machining efficiency, but also easily leads to improper clamping due to human error, increasing the risk of workpiece falling off or being damaged. Therefore, further improvement is needed. Summary of the Invention

[0005] In order to reduce the number of disassembly and assembly operations during workpiece cutting and improve processing efficiency, this application provides a workpiece cutting system.

[0006] The workpiece cutting system provided in this application adopts the following technical solution:

[0007] A workpiece cutting system includes a lathe body with a turning station. A turning seat and a clamping seat are respectively arranged within the turning station. The turning seat is slidably mounted within the turning station, and multiple cutting heads are rotatably mounted on the turning seat at intervals. The clamping seat is located on one side of the turning seat, and a rotating shaft is rotatably mounted within the clamping seat. A clamping block is provided on the rotating shaft. The clamping block includes a fixed part and a movable part. The fixed part is located on the rotating shaft, and the movable part is slidably mounted on the rotating shaft. A clamping area is formed between the fixed part and the movable part for one end of the workpiece to extend into. The clamping seat is provided with an opening and closing assembly for driving the movable part closer to or away from the fixed part.

[0008] By adopting the above technical solution, a rotating shaft and a clamping block are set inside the clamping seat. During cutting operations, the workpiece is clamped and fixed by the clamping block. Then, in conjunction with the sliding of the turning seat and the high-speed rotation of the cutting head, the cutting head can perform cutting machining on the workpiece surface. After one machining position of the workpiece is completed, the rotating shaft is driven to rotate a certain angle, so that other machining positions of the workpiece face the turning seat, thereby enabling the cutting head to machine different machining positions of the workpiece, reducing the number of disassembly and assembly operations during the workpiece cutting process and improving machining efficiency. Extending one end of the workpiece into the clamping area, the movable part is driven close to the fixed part, so that the fixed part and the movable part together clamp the workpiece, thereby fixing the workpiece on the rotating shaft, facilitating cutting machining by the cutting head.

[0009] Optionally, a loading tray is provided on one side of the lathe body, a moving rail is mounted on the lathe body, a moving seat is slidably installed on the moving rail, and a gripper for transferring the workpiece is connected to the moving seat.

[0010] By adopting the above technical solution, a large number of workpieces are arranged in a regular manner through the loading tray, and the workpieces on the loading tray are transferred one by one to the turning station for cutting and processing by the gripper, thereby improving the overall production efficiency.

[0011] Optionally, multiple lathe bodies are arranged at intervals, and the length direction of the moving track is consistent with the arrangement direction of the multiple lathe bodies.

[0012] By adopting the above technical solution, and by setting up multiple sets of lathe bodies with the length direction of the moving track aligned with the arrangement direction of the multiple sets of lathe bodies, the turning operations of the multiple sets of lathe bodies can be staggered in actual production. During the turning operation of the first set of lathe bodies, the gripper can "load" and "unload" materials onto the other lathe bodies. This achieves continuous automated operation of multiple sets of lathe bodies, reduces the working interval of the gripper, and effectively improves work efficiency.

[0013] Optionally, the feeding tray has a feeding slide, and a receiving seat is installed at the opening of the feeding slide. The receiving seat has a receiving groove on the side wall near the feeding slide. The workpiece includes a rod body and a rod head. The rod head is connected to one end of the rod body, and the outer diameter of the rod head is larger than the outer diameter of the rod body. When the workpiece slides out of the feeding slide, the rod body moves into the receiving groove, and the rod head abuts against the upper surface of the receiving seat for the gripper to grasp.

[0014] By adopting the above technical solution, the workpieces are regularly arranged on the feeding tray and fed into the feeding slide. The workpieces in the feeding slide slide slide out one by one from the opening of the feeding slide slide and are transferred to the receiving seat. At this time, the rod body moves into the receiving groove and the rod head abuts against the upper surface of the receiving seat to realize the "hanging" of the workpieces for the gripper to grab, thereby improving the operational stability of the workpiece transfer.

[0015] Optionally, the receiving seat is slidably installed at the opening of the feeding slide. When the receiving groove of the receiving seat moves out of the opening of the feeding slide, the side wall of the receiving seat blocks the opening of the feeding slide.

[0016] By adopting the above technical solution, after the workpiece at the opening of the feeding chute falls into the receiving groove of the receiving seat, the receiving seat is driven to slide, so that the workpiece in the receiving groove can avoid the feeding tray, allowing the gripper to easily remove it. Furthermore, in this state, the side wall of the receiving seat blocks the opening of the feeding chute, thereby limiting the workpiece from continuing to slide out of the feeding chute, reducing the possibility of the workpiece falling, and improving feeding stability.

[0017] Optionally, the turning station is equipped with a rotating disk, one end of the rotating shaft extends out of the clamping seat and is coaxially connected to the rotating disk, and the outer peripheral wall of the rotating disk is coaxially provided with a mating gear; a drive shaft is rotatably mounted on one side of the rotating disk, and a drive disk is coaxially connected to the drive shaft, and the outer peripheral wall of the drive disk is coaxially provided with an arc-shaped rack, which intermittently meshes with the mating gear for transmission.

[0018] By adopting the above technical solution, when it is necessary to change the orientation of the workpiece to perform cutting processing on different machining positions of the workpiece, the drive shaft is driven to rotate. Each rotation of the drive shaft, under the meshing of the arc rack and the mating gear, enables the rotating disk to rotate at a specific angle, thereby rotating other machining positions of the workpiece to face the turning seat, improving the overall operational convenience of the structure and the workpiece rotation accuracy.

[0019] Optionally, the surface of the rotating disk is provided with a first positioning disk, and the outer peripheral wall of the first positioning disk has a first positioning surface; the surface of the driving disk is provided with a second positioning disk, and the outer peripheral wall of the second positioning disk has a second positioning surface and a clearance notch respectively; when the arc-shaped rack meshes with the mating gear, the clearance notch of the second positioning disk faces the first positioning disk; when the arc-shaped rack disengages from the mating gear, the first positioning surface of the first positioning disk abuts against the second positioning surface of the second positioning disk.

[0020] By adopting the above technical solution, the position of the rotating disk is locked through the cooperation of the first and second positioning disks. This means the drive disk can rotate the rotating disk, but the rotating disk cannot rotate the drive disk. This reduces the possibility of the rotating disk rotating freely during the cutting process, which could cause the workpiece to become misaligned, thus improving the stability of the cutting process.

[0021] Optionally, a drive gear is coaxially connected to the drive shaft, and a drive rack is slidably installed in the turning station, with the drive gear and drive rack meshing and transmitting power; a drive block is detachably connected to the drive rack, and when the turning seat slides away from the clamping seat, the turning seat pushes the drive rack to slide through the drive block, thereby forcing the drive shaft to rotate.

[0022] By adopting the above technical solution, when the workpiece orientation needs to be adjusted, the turning stand is driven to slide away from the clamping seat. During this process, the turning stand pushes the drive block, which in turn drives the drive rack to slide away from the clamping seat. Under the meshing of the drive rack and drive gear, the drive shaft rotates, allowing the rotating shaft to rotate at a specific angle to rotate the workpiece to face the turning stand from different machining positions. This greatly improves the operational convenience of the overall structure and reduces equipment investment costs. Furthermore, for workpieces with only one machining position (i.e., where workpiece orientation adjustment is not required), the drive block can be detached from the drive rack, depriving the drive rack of its driving source. This ensures that when the turning stand slides away from the clamping seat, it cannot drive the rotating shaft to rotate, greatly improving the adaptability of the overall structure.

[0023] Optionally, a return spring is provided between the drive rack and the lathe body. The return spring normally forces the drive rack to slide towards the side closer to the clamping seat. The drive gear is rotatably connected to the drive shaft. One-way rotating parts are provided between the drive gear and the drive shaft, and between the drive shaft and the lathe body.

[0024] By adopting the above technical solution and setting a unidirectional rotating component to control the rotation direction of the drive shaft, it is ensured that when the turning stand slides away from the clamping seat, the drive shaft can rotate and drive the workpiece to rotate by a specific angle. When the turning stand slides towards the clamping seat, the return spring forces the drive rack to slide towards the clamping seat. During this process, the drive gear cannot drive the drive shaft to rotate, thus ensuring that the workpiece cannot rotate and improving the overall operational stability of the structure.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By using a rotating shaft and clamping blocks, the workpiece is clamped and fixed during cutting operations. Then, in conjunction with the sliding of the turning stand and the high-speed rotation of the cutting head, the cutting head can perform cutting operations on the workpiece surface. After one machining position of the workpiece is completed, the rotating shaft is driven to rotate a certain angle, causing other machining positions of the workpiece to face the turning stand. This allows the cutting head to machine different machining positions of the workpiece, reducing the number of disassembly and reassembly operations during the cutting process and improving machining efficiency.

[0027] 2. By setting up multiple sets of lathe bodies, with the length direction of the moving track aligned with the arrangement direction of the multiple sets of lathe bodies, the turning operations of the multiple sets of lathe bodies can be staggered in actual production. During the turning operation of the first set of lathe bodies, the gripper can "load" and "unload" materials onto the other lathe bodies. This achieves continuous automated operation of multiple sets of lathe bodies, reduces the working interval of the gripper, and effectively improves work efficiency.

[0028] 3. When workpiece orientation needs adjustment, the turning stand is driven to slide away from the clamping seat. During this process, the turning stand pushes the drive block, which in turn drives the drive rack to slide away from the clamping seat. The meshing of the drive rack and drive gear rotates the drive shaft, allowing it to rotate at a specific angle. This allows the workpiece to be rotated to face the turning stand from different machining positions, greatly improving the overall operational convenience and reducing equipment investment costs. Furthermore, for workpieces with only one machining position (i.e., no workpiece orientation adjustment is required), the drive block can be detached from the drive rack, depriving it of its driving source. This ensures that when the turning stand slides away from the clamping seat, it cannot drive the rotation shaft, significantly improving the overall structural adaptability.

[0040] The following combination Figures 1-10 This application will be described in further detail. Example 1

[0041] This application discloses a workpiece cutting system for cutting workpieces.

[0042] Reference Figure 1 In this embodiment, the workpiece 9 to be processed includes a shaft 91 and a head 92. The head 92 is fixedly connected to one end of the shaft 91, and the outer diameter of the head 92 is larger than the outer diameter of the shaft 91. A machined ball head 93 is integrally formed on the shaft 91. The specific cutting process of the workpiece 9 is: cutting the head 92 and cutting two cutting surfaces 931 on the machined ball head 93.

[0043] Reference Figure 2 , Figure 3 A workpiece cutting system includes a lathe body 1, which has a turning station 11 for cutting workpieces 9. In this embodiment, there are two lathe bodies 1, which are arranged side by side with intervals. Each lathe body 1 has a loading tray 5 on one side. The loading tray 5 is a vibratory plate with a loading slide 51. The workpieces 9 are arranged regularly in the loading tray 5 and slide out along the loading slide 51.

[0044] Reference Figure 2 , Figure 4 A receiving seat 7 is slidably installed at the opening of the feeding slide 51. The sliding direction of the receiving seat 7 is perpendicular to the length direction of the feeding slide 51. A receiving groove 71 is formed on the side wall of the receiving seat 7 near the feeding slide 51. When the workpiece 9 slides out of the feeding slide 51, the rod body 91 of the workpiece 9 moves into the receiving groove 71, and the rod head 92 of the workpiece 9 abuts against the upper surface of the receiving seat 7. And when the receiving groove 71 of the receiving seat 7 moves out of the opening of the feeding slide 51, the side wall of the receiving seat 7 blocks the opening of the feeding slide 51.

[0045] A movable rail 6 is mounted on the lathe body 1, and the length direction of the movable rail 6 is consistent with the arrangement direction of the two lathe bodies 1. A movable seat 61 is slidably mounted on the movable rail 6, and a first slide rail (not shown in the figure) is installed inside the movable seat 61. The first slide rail is horizontally set, and its length direction is perpendicular to the length direction of the movable rail 6. A first slide block (not shown in the figure) is slidably mounted on the first slide rail. Both the movable seat 61 and the first slide block can be driven by a linear motor (not shown in the figure).

[0046] A connecting sleeve 63 is fixedly installed at the bottom of the first slide. A lifting rod 64 is slidably installed inside the connecting sleeve 63. The lower end of the lifting rod 64 extends out of the connecting sleeve 63 and is fixedly installed on a lifting seat 641. The lifting rod 64 can be driven by a linear motor (not shown in the figure). A tilting seat 642 is rotatably installed on the lifting seat 641. The tilting seat 642 is driven by a motor. A gripper 62 is fixedly installed on the tilting seat 642. The gripper 62 is a chuck cylinder. The gripper 62 is used to grip the rod head 92 of the workpiece 9 on the receiving seat 7 and transfer it to the turning station 11 of the lathe body 1.

[0047] Reference Figure 3 The turning station 11 is equipped with a turning seat 2 and a clamping seat 3. A second slide rail 111 is installed within the turning station 11, and a second slide block is slidably mounted on the second slide rail 111. A third slide rail 112 is mounted on the second slide block, with its length direction perpendicular to the length direction of the second slide rail 111. The turning seat 2 is slidably mounted on the third slide rail 112. The arrangement of the second and third slide rails 111 and 112 allows the turning seat 2 to slide along the X-axis and Y-axis. The sliding of the turning seat 2 along both the X-axis and Y-axis can be driven by a linear motor (not shown in the figure).

[0048] Multiple mounting seats 22 are fixedly mounted on the turning stand 2. The mounting seats 22 are arranged at intervals along the Y-axis (i.e., along the length direction of the third slide rail 112). A cutting head 21 is rotatably mounted on each mounting seat 22. The cutting head 21 is driven by a motor, which enables the cutting head 21 to rotate at high speed to cut the workpiece 9.

[0049] Reference Figure 3 , Figure 5 The clamping seat 3 is fixedly installed on the inner wall of the turning station 11 and located on one side of the turning seat 2. When the turning seat 2 slides along the X-axis (i.e., when the turning seat 2 slides along the length direction of the second slide rail 111), the turning seat 2 moves closer to or away from the clamping seat 3. The top of the clamping seat 3 has a protective cover 33, and the bottom of the clamping seat 3 is equipped with an inclined guide plate 34 to allow the chips generated by cutting to slide to the bottom of the turning station 11. A cooling nozzle (not shown in the figure) is installed on one side of the clamping seat 3. The cooling nozzle is used to spray coolant outward to cool the cutting head 21, thereby protecting the cutting head 21, reducing the turning temperature, cleaning and removing chips, and preventing rust. The cutting fluid and coolant in this equipment can be recycled after filtration and collection for reuse to save resources.

[0050] Reference Figure 5 , Figure 6 The clamping seat 3 has a groove 35 on its side wall near the turning station 2. A rotating shaft 31 is rotatably mounted in the groove 35. In this embodiment, the rotating shaft 31 is vertically arranged. The lower end of the rotating shaft 31 extends out of the clamping seat 3 and is coaxially connected to a first bevel gear 311. A second bevel gear 113 is rotatably mounted on the inner wall of the turning station 11. The first bevel gear 311 and the second bevel gear 113 mesh and transmit power. The second bevel gear 113 is driven by a motor, thereby enabling the rotating shaft 31 to rotate around its own central axis.

[0051] A clamping block 32 is mounted on the rotating shaft 31. The clamping block 32 includes a fixed part 321 and a movable part 322. The fixed part 321 is fixedly mounted on the rotating shaft 31, and the movable part 322 is slidably mounted on the rotating shaft 31 to allow for lifting and lowering. The movable part 322 is located above the fixed part 321, and a clamping area 323 is formed between the fixed part 321 and the movable part 322. The end of the rod body 91 away from the rod head 92 extends into the clamping area 323. It should be noted that in this embodiment, the clamping block 32 clamps and fixes the end of the rod body 91 away from the rod head 92. In practical applications, it can also clamp and fix the processed ball head 93 to enhance the clamping stability. The specific clamping position of the clamping block 32 depends on the processing technology of the workpiece 9.

[0052] The clamping seat 3 is equipped with a tensioning assembly 4 for driving the movable part 322 to move closer to or away from the fixed part 321. The tensioning assembly 4 includes a pressure plate 41 and a compression spring 42. The pressure plate 41 is slidably installed in the groove 35, located on the side of the movable part 322 away from the fixed part 321. A drive cylinder is installed in the groove 35, with its cylinder body fixedly installed on the inner wall of the groove 35. The piston rod of the drive cylinder is fixedly connected to the pressure plate 41. When the piston rod of the drive cylinder retracts inward, the pressure plate 41 presses the movable part 322, forcing the fixed part 321 and the movable part 322 to clamp together at the end of the workpiece 9 rod 91 away from the rod head 92. One end of the compression spring 42 is fixedly connected to the fixed part 321, and the other end is fixedly connected to the movable part 322. Under normal conditions, the compression spring 42 forces the movable part 322 to lift away from the fixed part 321.

[0053] Reference Figure 7 Support columns 411 are fixedly installed on both sides of the pressure plate 41. When the length direction of the rod body 91 of the workpiece 9 is rotated to be consistent with the length direction of the third slide rail 112, the outer wall of the support column 411 abuts against the outer wall of the rod head 92 of the workpiece 9, and the clamping block 32 clamps the rod body 91 to improve the fixing effect of the workpiece 9.

[0054] The implementation principle of Embodiment 1 of this application is as follows: By setting up two sets of lathe bodies 1, and the length direction of the moving track 6 is consistent with the arrangement direction of the two sets of lathe bodies 1, the turning operations of the two sets of lathe bodies 1 can be staggered in actual production. During the turning operation of the first set of lathe bodies 1, the gripper 62 can "load" and "unload" the second set of lathe bodies 1. This enables continuous automated operation of multiple sets of lathe bodies 1, reduces the working interval of the gripper 62, and effectively improves work efficiency.

[0055] When workpiece 9 is transferred, workpiece 9 is regularly arranged on the loading tray 5 and the loading slide 51. Workpiece 9 in the loading slide 51 slides out one by one from the opening of the loading slide 51 and is transferred to the receiving seat 7. At this time, the rod body 91 moves into the receiving groove 71 and the rod head 92 abuts against the upper surface of the receiving seat 7 to realize the "hanging" of workpiece 9, so that the gripper 62 can grab it and transfer it to the clamping seat 3 of the turning station 11, thereby improving the running stability of workpiece 9 transfer.

[0056] A rotating shaft 31 and a clamping block 32 are installed inside the clamping seat 3. During cutting operations, the workpiece 9 is clamped and fixed by the clamping block 32. Then, in conjunction with the sliding of the turning seat 2 and the high-speed rotation of the cutting head 21, the cutting head 21 can perform cutting operations on the surface of the workpiece 9. After one machining position of the workpiece 9 is completed, the rotating shaft 31 is driven to rotate a certain angle so that other machining positions of the workpiece 9 face the turning seat 2. This allows the cutting head 21 to machine different machining positions of the workpiece 9, reducing the number of disassembly and assembly operations during the cutting process and improving machining efficiency. Example 2

[0057] This application discloses a workpiece cutting system.

[0058] The workpiece cutting system disclosed in this application differs from that in Embodiment 1 in that:

[0059] Reference Figure 8 In this embodiment, a rotating disk 12 is rotatably installed in the turning station 11. The rotating disk 12 is located at the bottom of the clamping seat 3. The lower end of the rotating shaft 31 extends out of the clamping seat 3, passes through the guide plate 34, and is coaxially fixed to the rotating disk 12. A mating gear 121 is coaxially fixed to the outer peripheral wall of the rotating disk 12. A drive shaft 13 is rotatably installed in the turning station 11. The drive shaft 13 is located on one side of the rotating disk 12. A drive disk 14 is coaxially fixed to the drive shaft 13. An arc-shaped rack 141 is coaxially fixed to the outer peripheral wall of the drive disk 14. The virtual central axis of the arc-shaped rack 141 is coaxially set with the drive shaft 13. The arc-shaped rack 141 and the mating gear 121 engage intermittently.

[0060] In this embodiment, a first positioning disk 15 is fixedly mounted on the surface of the rotating disk 12. The outer peripheral wall of the first positioning disk 15 has a plurality of first positioning surfaces 151, which are arranged at intervals around the central axis of the rotating shaft 31. A second positioning disk 16 is fixedly mounted on the surface of the driving disk 14. The outer peripheral wall of the second positioning disk 16 has a second positioning surface 161 and a clearance notch 162. When the arc-shaped rack 141 meshes with the mating gear 121, the clearance notch 162 of the second positioning disk 16 faces the first positioning disk 15. When the arc-shaped rack 141 disengages from the mating gear 121, the first positioning surface 151 of the first positioning disk 15 abuts against the second positioning surface 161 of the second positioning disk 16.

[0061] Reference Figure 9 , Figure 10 A drive gear 17 is coaxially connected to the drive shaft 13, and the drive gear 17 and the drive disc 14 are offset along the axial direction of the drive shaft 13. A rotating ring 19 is coaxially fixed to the inner peripheral wall of the drive gear 17, and the rotating ring 19 is rotatably mounted on the outer peripheral wall of the drive shaft 13. The drive gear 17 is rotatably connected to the drive shaft 13 through the rotating ring 19. A rotating groove 114 is provided on the inner wall of the lathe body 1, and the drive shaft 13 is rotatably mounted in the rotating groove 114. One-way rotating parts 8 are provided between the drive gear 17 and the drive shaft 13, and between the drive shaft 13 and the lathe body 1. The following description takes the one-way rotating part 8 between the drive gear 17 and the drive shaft 13 as an example. The one-way rotating part 8 between the drive shaft 13 and the lathe body 1 can be obtained in the same way.

[0062] The unidirectional rotating component 8 includes a limiting post 81 and a limiting spring 82. A limiting groove 191 is formed on the inner wall of the rotating ring 19 of the drive gear 17 (i.e., a limiting groove 191 is also formed on the inner wall of the rotating groove 114). The limiting groove 191 has a limiting arc surface 192, with a first point 193 and a second point 194 formed at its two ends. The distance from the first point 193 to the center of the drive shaft 13 is greater than the distance from the second point 194 to the center of the drive shaft 13. The limiting post 81 is disposed within the limiting groove 191. One end of the limiting spring 82 is fixedly connected to the limiting post 81, and the other end is fixedly connected to the inner wall of the limiting groove 191. Under normal conditions, the limiting spring 82 forces the limiting post 81 to slide towards the second point 194, simultaneously abutting against the limiting arc surface 192 and the outer peripheral wall of the drive shaft 13.

[0063] A drive rack 18 is slidably mounted within the turning station 11, and the drive gear 17 and the drive rack 18 mesh with each other. A return spring (not shown in the figure) is provided between the drive rack 18 and the lathe body 1. The return spring, in its normal state, forces the drive rack 18 to slide towards the side closer to the clamping seat 3. A drive block 181 is mounted on the drive rack 18, and the drive block 181 is detachably mounted on the drive rack 18 by bolt connection. When the turning seat 2 slides away from the clamping seat 3, the turning seat 2 pushes the drive rack 18 to slide through the drive block 181, and under the action of the limit post 81, drives the drive shaft 13 to rotate. When the turning seat 2 slides towards the side closer to the clamping seat 3, the drive rack 18 slides towards the side closer to the clamping seat 3 under the elastic force of the return rack, and the drive shaft 13 does not rotate during this process.

[0064] It should be noted that in this embodiment, each time the turning seat 2 retracts, the drive gear 17 rotates one revolution, and the rotating disk 12 rotates 90°, that is, each time the turning seat 2 retracts, the workpiece 9 rotates 90°.

[0065] The implementation principle of Embodiment 2 of this application is as follows: When it is necessary to change the orientation of the workpiece 9 (to cut the ball end 93 of the workpiece 9), the turning seat 2 is driven to retract (the turning seat 2 slides away from the clamping seat 3). The turning seat 2 pushes the drive block 181, causing the drive rack 18 to slide away from the clamping seat 3, thereby driving the drive shaft 13 to rotate, which in turn drives the workpiece 9 to rotate 90°, so that the ball end 93 of the workpiece 9 faces the cutting head 21.

[0066] After driving the turning stand 2 close to the clamping stand 3 and cutting a cutting surface 931 on the surface of the ball end 93 by the cutting head 21, the orientation of the workpiece 9 is changed by the retraction action of the turning stand 2, thereby cutting multiple cutting surfaces 931 on the surface of the ball end 93 of the workpiece 9, which greatly improves the operational convenience of the overall structure and reduces the equipment investment of the overall structure.

[0067] By arranging two sets of unidirectional rotating parts 8 on the drive shaft 13, it is ensured that the drive shaft 13 can only rotate in one direction. When the drive rack 18 returns to the side closer to the clamping seat 3, it is ensured that the drive shaft 13 cannot rotate, thereby ensuring the rotational accuracy of the workpiece 9. During the cutting process of the cutter head 21 on the workpiece 9, the clamping block 32 is pressed against by the pressure plate 41, and the cooperation of the first positioning plate 15 and the second positioning plate 16 forms a lock on the rotating shaft 31. The support column 411 of the pressure plate 41 can share the rotational thrust from the rotating shaft 31 to the cutter head 21, ensuring the locking of the workpiece 9 position during the cutting process, greatly improving the machining quality of the workpiece 9.

[0068] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
