Description

Technical Field

[0001] This invention application relates to the technical field of automated processing equipment for shaft parts, specifically to an automated production line equipment for transmission shafts. Background Technology

[0002] As a core component of mechanical transmission systems, precision drive shafts typically require multiple precision machining processes, such as turning, milling keyways, milling annular grooves, and cutting. Currently, the industry widely adopts high-precision CNC Swiss-type machine tools to achieve continuous automated machining of such parts, which can ensure the dimensional accuracy and machining efficiency of drive shafts.

[0003] After machining on a Swiss-type lathe, most existing drive shafts are centrally stored and circulated using open conveyor troughs, collection boxes, or turnover pallets. This lacks constraints and limitations on individual drive shafts, making them prone to random tumbling and chaotic posture during movement and stacking. This results in multiple drive shafts squeezing, colliding, and rubbing against each other, causing scratches, deformation, or keyway collisions, directly reducing product yield. Furthermore, subsequent manual repositioning is required, resulting in low automation and making it difficult to meet the demands of efficient, stable, and high-quality mass automated production. Summary of the Invention

[0004] To address the aforementioned issues, an automated production line for drive shafts is provided. By incorporating a Swiss-type machining center, conveyor rails, housing, support components, and adjustment mechanisms, the drive shafts are independently separated and arranged in an orderly manner, preventing stacking, collisions, and scratches during transport.

[0005] To address the problems of existing technologies, this invention provides an automated production line equipment for drive shafts, including a Swiss-type machining center and a feeding mechanism, as well as a conveyor track, several boxes, and an adjustment mechanism. The conveyor track is horizontally arranged; the several boxes move along the conveyor track, and each box has a vertical hole in its center for placing the drive shaft. A support component is provided inside each box to limit the downward travel of the drive shaft. The adjustment mechanism includes a detection component and a rotary drive component. The detection component detects the falling state of the drive shaft, and the rotary drive component drives the drive shaft to rotate and align itself. When the drive shaft has not fully fallen, the rotary drive component drives the drive shaft to rotate and align itself. When the keyway of the drive shaft rotates to align with the support component, the drive shaft fully falls into the vertical hole.

[0006] Preferably, the support assembly includes a support member and an axial limiting member; the support member extends into the vertical hole; the axial limiting member is disposed at the lower end of the support member, and the axial limiting member is used to limit the rotation of the drive shaft.

[0007] Preferably, the detection component includes a through-beam photoelectric sensor, which is disposed on both sides of the adjustment mechanism.

[0008] Preferably, the rotary drive assembly includes a turntable, a drive element, and a transverse drive; the turntable is horizontally positioned; the drive element drives the turntable to rotate; and the transverse drive drives the turntable to move horizontally.

[0009] Preferably, the outer circumferential surface of the turntable is fitted with a rubber layer.

[0010] Preferably, there are two rotary drive assemblies, which are used to synchronously drive the drive shaft to rotate from both sides of the drive shaft.

[0011] Preferably, the adjustment mechanism further includes a pressing component for applying a downward thrust to the drive shaft.

[0012] Preferably, the pressing assembly includes a pressing driver and a pressing block; the pressing driver is disposed above the moving path of the housing; the pressing block is rotatably connected to the output end of the pressing driver.

[0013] Preferably, the pressing assembly further includes a buffer connection assembly for buffering the pressing force provided by the pressing driver to the pressing block.

[0014] Preferably, the support member includes a roller, one end of which is connected to the housing via a bearing, and the diameter of the roller is smaller than the width of the keyway of the drive shaft.

[0015] The advantages of this invention compared to the prior art are: 1. This invention comprises a Swiss-type machining center, a conveyor track, a housing, a support assembly, and an adjustment mechanism. The Swiss-type machining center is used to complete the cutting, keyway milling, annular groove milling, and cutting of the drive shaft. The housing accommodates the drive shaft through a central vertical hole. The support assembly restricts the downward movement of the drive shaft when the keyway is misaligned. The housing moves along the conveyor track and conveys the drive shaft. The detection assembly is used to detect the falling state of the drive shaft in real time. The rotation drive assembly is used to drive the drive shaft to rotate and align. Through the cooperation of each component, the drive shaft is constrained within the vertical hole of the housing throughout the entire process of machining, conveying, positioning, and placement, thereby achieving independent separation and orderly arrangement of the drive shaft, preventing stacking, collision, and scratches during circulation.

[0016] 2. This invention includes a support member and an axial limiting member. The support member extends into the vertical hole of the housing to support the lower end face of the drive shaft and limit its downward stroke, keeping the drive shaft in an unpositioned state. The axial limiting member abuts against the keyway wall after the drive shaft is positioned and restricts its circumferential rotation. The rotary drive assembly drives the drive shaft to rotate so that the keyway aligns with the support member. The housing and the vertical hole are used to position and accommodate the drive shaft. Through the cooperation of the support member and the axial limiting member, the downward stroke of the drive shaft is controlled while circumferential locking is achieved after positioning, ensuring that all drive shafts are in a consistent fixed posture within the housing, thereby preventing the drive shaft from shaking during movement on the conveyor track.

[0017] 3. The present invention is equipped with a through-beam photoelectric sensor, which identifies the high and low position of the drive shaft in a non-contact manner, thereby providing accurate trigger and stop signals for the rotary drive assembly and avoiding malfunctions of the equipment.

Detailed Implementation

[0031] To further understand the features, technical means, and specific objectives and functions achieved by this invention application, the invention application will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 12 The diagram shows an automated production line equipment for a drive shaft, comprising a Swiss-type machining center 1 and a feeding mechanism 6, as well as a conveyor track 2, several boxes 3, and an adjustment mechanism 5. The conveyor track 2 is horizontally arranged. The several boxes 3 move along the conveyor track 2, and each box 3 has a vertical hole 31 in its center for placing the drive shaft. A support component 4 is provided inside each box 3 to limit the downward travel of the drive shaft. The adjustment mechanism 5 includes a detection component 51 and a rotary drive component 52. The detection component 51 detects the falling state of the drive shaft, and the rotary drive component 52 drives the drive shaft to rotate and align itself. When the drive shaft has not fully fallen, the rotary drive component 52 drives the drive shaft to rotate and align itself. When the keyway of the drive shaft rotates to align with the support component 4, the drive shaft fully falls into the vertical hole 31.

[0033] After the Swiss-type machining center 1 completes the cutting, keyway milling, annular groove milling, and cut-off machining of the drive shaft, it places the drive shaft into the vertical hole 31 in the middle of the housing 3. If the keyway on the drive shaft is misaligned with the support component 4 inside the housing 3, the end of the drive shaft rests on the support component 4 inside the housing 3. The support component 4 restricts the downward stroke of the drive shaft, keeping it in a partially lowered state. Several housings 3 move on the horizontally set conveyor track 2. When the housing 3 moves to the position of the adjustment mechanism 5, it stops. The detection component 51 detects the current falling state of the drive shaft inside the housing 3 in real time. If the detection component 51 detects that the drive shaft cannot pass through the support component 4 to complete the falling motion due to the misalignment of the end keyway with the support component 4, the rotation drive component 52 immediately starts to drive the drive shaft to rotate circumferentially around its own axis. During continuous rotation, the drive shaft constantly adjusts the circumferential angle of the keyway until it rotates to a position perfectly aligned with the support component 4. At this point, the support component 4 automatically releases its restriction on the downward movement of the drive shaft, allowing it to fall completely into the vertical hole 31 under its own gravity, completing automatic positioning and reliable placement. Through the cooperation of the conveyor track 2, the box 3, the support component 4, the detection component 51, and the rotary drive component 52, the drive shaft is constrained within the vertical hole 31 of the box 3 throughout the entire process of processing, conveying, positioning, and placement. This achieves independent separation and orderly arrangement of the drive shafts, preventing stacking, collisions, and scratches during transit.

[0034] Reference Figure 4 As shown: The support assembly 4 includes a support member 41 and an axial limiting member 42; the support member 41 extends into the vertical hole 31; the axial limiting member 42 is disposed at the lower end of the support member 41, and the axial limiting member 42 is used to limit the rotation of the transmission shaft.

[0035] The support member 41 extends into the vertical hole 31 in the middle of the housing 3. Before the keyway of the drive shaft is aligned with the support member 41, the support member 41 directly supports the lower end face of the drive shaft, supporting the drive shaft in the vertical hole 31 and limiting the downward stroke of the drive shaft, keeping the drive shaft in a state of not being fully seated. When the rotary drive assembly 52 drives the drive shaft to rotate around its own axis, and the keyway rotates with the drive shaft until it is aligned with the support member 41, the drive shaft is no longer blocked by the support member 41 and completes the downward positioning action along the vertical hole 31. At this time, the axial limiting member 42 set at the lower end of the support member 41 enters the keyway of the drive shaft and forms a mating abutment relationship with the two opposite groove walls of the keyway. Utilizing the structural constraint between the axial limiting member 42 and the keyway, the circumferential rotation of the drive shaft is directly restricted, keeping the drive shaft in a stable posture within the vertical hole 31 of the housing 3. By cooperating with the support member 41 and the axial limiting member 42, the circumferential locking after the transmission shaft is positioned is achieved while controlling the downward stroke of the transmission shaft. This ensures that all transmission shafts are in a consistent fixed posture within the box 3, thereby preventing the transmission shafts from shaking during the movement of the conveyor track 2.

[0036] Reference Figure 3 and Figure 5 As shown: The detection component 51 includes a through-beam photoelectric sensor 511, which is disposed on both sides of the adjustment mechanism 5.

[0037] The through-beam photoelectric sensor 511 is fixedly installed on both sides of the adjustment mechanism 5. The two sensors are arranged opposite each other and form a horizontal detection optical path that runs through the moving path of the housing 3. When the housing 3, which is equipped with the drive shaft, moves along the conveyor track 2 to the position of the adjustment mechanism 5, the drive shaft is located between the optical paths of the through-beam photoelectric sensor 511. If the drive shaft does not fall completely due to misalignment between the keyway and the support member 41, the upper part of the drive shaft will directly block the optical path between the transmitting end and the receiving end of the through-beam photoelectric sensor 511, and the sensor will immediately determine that the drive shaft is not in the correct position. When the rotary drive assembly 52 drives the drive shaft to rotate, aligning the keyway and the support member 41 and falling completely into the vertical hole 31, the protruding upper part of the drive shaft disappears, the optical path of the through-beam photoelectric sensor 511 is restored, and the sensor immediately determines that the drive shaft has been completely positioned. The through-beam photoelectric sensor 511 identifies the high and low position of the drive shaft in a non-contact manner, thereby providing accurate trigger and stop signals to the rotary drive assembly 52 and avoiding malfunctions of the equipment.

[0038] Reference Figure 3 and Figure 6 As shown: The rotary drive assembly 52 includes a turntable 521, a drive member 522, and a transverse drive 523; the turntable 521 is horizontally arranged; the drive member 522 is used to drive the turntable 521 to rotate; the transverse drive 523 is used to drive the turntable 521 to move horizontally.

[0039] When the photoelectric sensor 511 detects that the drive shaft has not fully descended and is in a state requiring adjustment, the transverse actuator 523 first activates, pushing the turntable 521 horizontally towards the drive shaft, so that the outer circumferential surface of the turntable 521 smoothly contacts the side wall of the drive shaft, forming a stable frictional contact. After contact is established, the drive unit 522 starts and outputs rotational power, driving the horizontally positioned turntable 521 to rotate continuously and uniformly. Friction is generated between the turntable 521 and the side wall of the drive shaft. Under the action of friction, the drive shaft is driven to rotate stably around its own axis, gradually adjusting the circumferential angle of the end keyway until the keyway aligns with the support member 41. After adjustment, the transverse actuator 523 reverses its action, driving the turntable 521 horizontally away from the drive shaft, releasing the contact with the drive shaft. The transverse actuator 523 realizes the feeding and avoidance of the turntable 521, and the drive unit 522 ensures that the turntable 521 rotates smoothly and evenly, thereby achieving the drive alignment of the drive shaft.

[0040] Reference Figure 6 and Figure 7As shown: The outer circumferential surface of the turntable 521 is fitted with a rubber layer 5211.

[0041] When the transverse actuator 523 drives the turntable 521 to move towards the drive shaft and brings the turntable 521 into contact with the side wall of the drive shaft, the rubber layer 5211 directly contacts the outer circumferential surface of the drive shaft. When the drive component 522 rotates the turntable 521, the high coefficient of friction of the rubber layer 5211 significantly increases the frictional force between the turntable 521 and the drive shaft, enabling the turntable 521 to stably drive the drive shaft to rotate around its own axis without slippage or free-spinning. Simultaneously, the soft texture of the rubber layer 5211 buffers the rigid contact pressure between the turntable 521 and the drive shaft, preventing the hard turntable 521 from directly squeezing or scratching the drive shaft surface, thus preventing appearance defects such as indentations and scratches on the drive shaft. By covering the outer circumference of the turntable 521 with the rubber layer 5211, the rotational drive process is ensured to be stable and reliable without slippage, while effectively protecting the drive shaft surface from damage, thereby maintaining the intact appearance and dimensional accuracy of the drive shaft during adjustment and transport.

[0042] Reference Figure 3 and Figure 8 As shown: There are two rotary drive assemblies 52, which are used to synchronously drive the drive shaft to rotate from both sides of the drive shaft.

[0043] Two rotary drive components 52 are provided in the adjustment mechanism 5, located symmetrically on the left and right sides of the drive shaft. When the photoelectric sensor 511 detects that the drive shaft has not fully descended and angle adjustment is required, the transverse drive 523 in the two rotary drive components 52 activates synchronously, pushing their respective turntables 521 horizontally towards the center of the drive shaft until both turntables 521 simultaneously adhere to the sidewalls of the drive shaft. Subsequently, the drive components 522 in the two rotary drive components 52 activate synchronously, driving the two turntables 521 to rotate in the same direction at the same speed, applying uniform and symmetrical rotary drive force from both sides of the drive shaft, causing the drive shaft to rotate smoothly around its own axis, adjusting the circumferential position of the keyway. After adjustment, the transverse drive 523 retracts synchronously, driving the turntables 521 away from the drive shaft, disengaging the drive engagement. The two rotary drive components 52 are arranged symmetrically on both sides, so that the drive shaft is subjected to balanced force and rotates smoothly during rotation, and there will be no offset problem caused by unilateral force, thus ensuring that the drive shaft remains centered in the vertical hole 31 of the housing 3.

[0044] Reference Figure 3 As shown: The adjustment mechanism 5 further includes a pressing component 53, which is used to apply a downward thrust to the drive shaft.

[0045] During the alignment process of the drive shaft within the vertical hole 31 of the housing 3, driven by the rotating drive components 52 on both sides, there is significant friction between the outer wall of the drive shaft and the rubber layer 5211 on the outer circumference of the turntable 521. This can easily lead to a jamming problem where the keyway is aligned with the support component 4, but the drive shaft is still restrained by friction and cannot fall under its own weight. Therefore, the pressing component 53 on the adjustment mechanism 5 operates synchronously, continuously applying a constant and stable downward thrust to the upper end of the drive shaft. This thrust remains in effect throughout the entire alignment process. When the keyway of the drive shaft rotates to the position aligned with the support component 4, the downward movement restriction of the drive shaft by the support component 4 is immediately released. The downward thrust applied by the pressing component 53 overcomes the frictional resistance of the rubber layer 5211 and the jamming force of the drive shaft, forcibly pushing the drive shaft vertically downward along the vertical hole 31, allowing the drive shaft to quickly, smoothly, and completely fall into the vertical hole 31 and complete its positioning. The pressing component 53 actively applies downward thrust to overcome the frictional jamming problem between the drive shaft and the rubber layer 5211, ensuring that the drive shaft can be immediately and reliably positioned after the keyway is aligned, and avoiding situations such as positioning delay or jamming.

[0046] Reference Figure 3 and Figure 9 As shown: The pressing assembly 53 includes a pressing driver 531 and a pressing block 532; the pressing driver 531 is disposed above the moving path of the housing 3; the pressing block 532 is rotatably connected to the output end of the pressing driver 531.

[0047] When the photoelectric sensor 511 detects that the drive shaft has not fully fallen and angle adjustment is required, the pressure driver 531 activates and extends its output end downward, driving the pressure block 532 to move vertically downward, so that the lower end face of the pressure block 532 is smoothly pressed against the upper end face of the drive shaft. At this time, the rotation drive components 52 on both sides synchronously drive the drive shaft to rotate around its own axis. Since the pressure block 532 and the output end of the pressure driver 531 can rotate relative to each other, the pressure block 532 will rotate freely synchronously under the drive of the drive shaft, always maintaining a close contact with the upper end face of the drive shaft, and there will be no relative sliding friction between them. During the entire process of drive shaft rotation alignment and keyway and support component 4 alignment, the pressure driver 531 continuously provides downward thrust, and the pressure block 532 rotates accordingly without hindering the rotation of the drive shaft, until the drive shaft is completely lowered into the vertical hole 31, and then the pressure driver 531 drives the pressure block 532 to return to its original position. The pressure driver 531 works in conjunction with the rotatable pressure block 532 to provide a continuous and stable downward auxiliary positioning thrust, and can fully adapt to the rotation of the drive shaft, thereby avoiding the problem of scraping the top between the pressure assembly 53 and the drive shaft.

[0048] Reference Figure 9 and Figure 10As shown: The pressing component 53 further includes a buffer connection component 533, which is used to buffer the pressing force provided by the pressing driver 531 to the pressing block 532.

[0049] Specifically, the buffer connection assembly 533 includes a connecting block 5331 and multiple springs 5332. The connecting block 5331 is connected to the output shaft of the pressure driver 531 through a bearing. The multiple springs 5332 are circumferentially arranged around the connecting block 5331, and the two ends of the springs 5332 are respectively connected to the pressure block 532 and the connecting block 5331.

[0050] When the pressure actuator 531 drives the output shaft to move downwards, the power is sequentially transmitted to the connecting block 5331, the spring 5332, and the pressure block 532. The spring 5332 is moderately compressed, converting the rigid downward pressure output by the pressure actuator 531 into a flexible buffer pressure, which is then smoothly applied to the upper end face of the drive shaft by the pressure block 532. During the drive shaft rotation alignment process, the connecting block 5331 rotates freely synchronously with the drive shaft under the cooperation of the bearings, and the spring 5332 maintains uniform force, adaptively compensating for the height deviation and downward stroke deviation of the drive shaft, so that the pressure block 532 always fits against the top of the drive shaft without generating rigid impact. After the keyway is aligned, the drive shaft falls smoothly under the action of flexible thrust. The buffer connection assembly 533 transforms the rigid downward pressure into a flexible buffer downward pressure, thereby avoiding problems such as damage and deformation of the drive shaft caused by the direct rigid pressure applied by the pressure actuator 531.

[0051] Reference Figure 4 , Figure 11 and Figure 12 As shown: The support member 41 includes a roller 411, one end of which is connected to the box body 3 via a bearing, and the diameter of the roller 411 is smaller than the width of the keyway of the transmission shaft.

[0052] The sliding friction between the support component 41 and the drive shaft can easily cause wear on the keyway or support component 41 and high rotational resistance. One end of the roller 411 is connected to the housing 3 through a bearing and can rotate freely. The diameter of the roller 411 is smaller than the width of the keyway. When the drive shaft rotates for alignment, the roller 411 rolls synchronously with the drive shaft, changing the sliding friction into rolling friction, which greatly reduces rotational resistance and reduces wear on the inner wall of the keyway and the support component 41. The smaller diameter of the roller 411 than the width of the keyway can prevent the keyway wall from contacting the roller 411 simultaneously during descent, thus avoiding jamming and ensuring smooth descent of the drive shaft. The cooperation of the roller 411, bearing and housing 3 improves the smoothness of the drive shaft rotation alignment, extends the service life of the support component 4, and ensures stable and jam-free descent, thus improving the long-term operational stability of the equipment.

[0053] Under the downward pressure applied by the pressing component 53, the end of the drive shaft will be in close contact with the surface of the support member 41. If the support member 41 is a fixed block, a hard relative sliding will occur between the end of the drive shaft and the support member 41 when the drive shaft rotates, which can easily cause scratches on the end surface of the drive shaft and wear on the keyway. In this structure, the roller 411 can rotate freely under the support of the bearing. When the rotation drive component 52 drives the drive shaft to rotate around its own axis for alignment, friction is generated between the end of the drive shaft and the roller 411. This friction will drive the roller 411 to rotate synchronously, changing the sliding friction between the two into rolling friction, which significantly reduces the rotational resistance. At the same time, the diameter of the roller 411 is smaller than the width of the keyway. When the drive shaft falls, there will be no jamming situation where the two sides of the keyway wall simultaneously clamp the roller 411, ensuring that the drive shaft falls smoothly into the vertical hole 31. The rotatable structure of the roller 411 and the bearing eliminates the hard sliding friction between the end of the drive shaft and the support member 41, thereby avoiding scratches on the end of the drive shaft and wear on the keyway, protecting the appearance and structural precision of the drive shaft.

[0054] The above embodiments only illustrate one or more implementation methods of this invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this invention, and these all fall within the protection scope of this invention. Therefore, the protection scope of this invention should be determined by the appended claims.
