[0016] Compared with existing technologies, a parallel-adjustable twin-spindle turning machine tool that adopts the above-mentioned technical solution has the following advantages: 1. In this invention, the automated feeding component, adjusting motor, adjusting screw, screw sleeve, sliding slot seat, moving plate, mounting box, rotating frame, fixed ring, and rotating ring work together to achieve automated feeding and precise positioning of the workpiece, effectively improving feeding efficiency and reducing manual intervention. The fixed motor drives the follower clamp to move inward synchronously through the drive gear, rotating gear ring, transmission gear, moving screw, and screw seat, completing the automatic positioning and clamping of the workpiece. The clamping is stable and reliable, adaptable to workpieces of different sizes, and improves the applicability of the equipment.

The automatic feeding component can simultaneously perform a new round of feeding when the shifting follower component transfers the workpiece to the second spindle mechanism, ensuring that the workpiece feeding does not require machine stoppage and reassembly during the operation between the first and second spindle mechanisms, realizing continuous processing of the workpiece and improving equipment utilization and production efficiency.

[0017] 2. In this invention, the coordinated movement of the rotating ring and the follower clamping block, combined with the mechanical transmission of the drive wheel, sliding rod, and return spring, achieves adaptive clamping and smooth transfer of the finished workpiece. Simultaneously, the friction generated by the rotation of the drive wheel smoothly transfers the workpiece to the storage bin. During the falling process of the finished workpiece, the buffer spring effectively absorbs the impact of the workpiece on the oscillating screen plate, significantly reducing the risk of collision damage. Combined with the hollow structure and oblique arrangement of the oscillating screen plate, efficient separation of the finished workpiece from attached debris is achieved. The debris falls below the screen plate, while the workpiece slides down the inclined surface to the support plate, ultimately completing the integrated operation of material collection and debris removal, greatly improving the collection efficiency and quality protection level of the processed workpiece.

[0018] 3. In this invention, by setting up an inclined feeding pipe and an electric push rod to work together, the automatic feeding and positioning of the workpiece is realized, which effectively reduces the manual intervention links, significantly improves the automation level and processing efficiency of the feeding process, and at the same time reduces the operation intensity and error probability.

The rotating ring 515 has an annular inner cavity inside. Multiple lead screw seats 514 are connected to one side of the follower clamp 511. The follower clamp 511 has anti-slip texture on one side. The other end of the lead screw seat 514 extends into the annular inner cavity. The lead screw seat 514 can be slidably connected to the annular inner cavity.

The movable lead screws 520 are connected to the lead screw base 514 via transmission. A transmission gear 521 is connected to the end of the movable lead screw 520 away from the lead screw base 514. Rotate the gear ring 516, which is rotatably connected to the annular inner cavity, and rotate the gear ring 516 to mesh with the transmission gear 521.

One end of the output shaft of the drive motor 504 is connected to a second connecting shaft. The second connecting shaft is rotatably connected to the mounting box 508 via a mounting plate.

One end of the first connecting shaft extends to the outside of the mounting box 508 and is connected to one side of the rotating frame 509. A fixed motor 519 is fixedly installed inside the rotating ring 515. One end of the output shaft of the fixed motor 519 is connected to a drive gear 518, which meshes with the rotating gear ring 516. Two balancing blocks 517 are symmetrically connected within the rotating ring 515, and the fixed motor 519 and the two balancing blocks 517 are arranged in an equal-angled circular array. Two sliding slot seats 507 are connected to both sides of the movable plate 506. The sliding slot seats 507 are slidably connected to the top of the frame 8. Sliding slots are provided on both sides of the frame 8. Two symmetrically arranged sliders are connected inside the sliding slot seats 507. The sliders are slidably connected inside the sliding slots. A lead screw sleeve 503 is disposed on one side of one of the sliding groove seats 507. A fixing plate is connected to one side of the lead screw sleeve 503, and the fixing plate is connected to one of the sliding groove seats 507. Adjustment motor 501 is fixedly installed on one side of one of the frames 8. One end of the output shaft of adjustment motor 501 is connected to adjustment screw 502. The other end of adjustment screw 502 is rotatably connected to one side of housing 2. Adjustment screw 502 is connected to screw sleeve 503 for transmission.

[0023] The specific usage method and working principle are as follows: During processing, the operator uses the automatic feeding component 7 to automatically feed the workpiece. During this process, the adjusting motor 501 drives the adjusting screw 502 to rotate, which in turn moves the screw sleeve 503. The screw sleeve 503, through the sliding slot seat 507 and the moving plate 506, moves the mounting box 508. The mounting box 508, through the rotating frame 509, moves the fixed ring 510 and the rotating ring 515 to the vicinity of the automatic feeding component 7. The automatic feeding component 7 then feeds the workpiece... The workpiece is pushed towards the rotating ring 515 and passes through it. Then, the fixed motor 519 drives the drive gear 518 to rotate, which in turn drives the rotating gear ring 516 to rotate. The rotating gear ring 516 drives multiple transmission gears 521 to rotate synchronously. The transmission gears 521 drive the follower clamping block 511 to move inward synchronously through the moving lead screw 520 and lead screw seat 514, thereby completing the automatic positioning and clamping of the workpiece. Afterward, the adjusting motor 501 drives the fixed ring 510 and the rotating ring 515 through mechanical transmission. After resetting, the drive motor 504 starts and drives the first bevel gear 512 to rotate via the second bevel gear 513. The first bevel gear 512 drives the rotating frame 509 to rotate 180 degrees. The rotating frame 509 drives the workpiece to rotate to a concentric position with the first spindle mechanism 3 via the fixed ring 510 and the rotating ring 515. The adjusting motor 501 continues to move towards the first spindle mechanism 3 via the moving plate 506, causing the workpiece to move towards the first spindle mechanism 3. The grippers on the first spindle mechanism 3 are driven by the drive source. After the workpiece is positioned and clamped, the first spindle mechanism 3 can remain in a rotating state. At this time, the first spindle mechanism 3 drives the rotating ring 515 to rotate through the transmission of the workpiece. Then, the fixed motor 519 drives multiple follower clamps 511 to release the clamping of the workpiece, completing the transfer and loading of the workpiece. After that, the moving plate 506 drives the fixed ring 510 and the rotating ring 515 to return to the center position of the frame 8. One of the turning tool mechanisms 4 performs turning processing on the workpiece on the first spindle mechanism 3. After the workpiece on the first spindle mechanism 3 is finished, the moving plate 506 moves towards the first spindle mechanism 3 under the action of the adjusting screw 502 and the screw sleeve 503, and the workpiece that was initially processed passes through the rotating ring 515. The fixed motor 519 repeats the previous operation and drives the follower clamping block 511 to adapt and clamp the workpiece through mechanical transmission. During this clamping process, the rotating ring 515 rotates in the fixed ring 510 under the transmission action of the workpiece. After the follower clamping block 511 completes the clamping of the workpiece, the first spindle mechanism 3 releases the clamping of the workpiece. Afterwards, the follower clamping block 511 moves in the direction of the second spindle mechanism 11 in coordination with the movement of the moving plate 506, and completes the clamping process of the workpiece in the first spindle mechanism 3, so that the second spindle mechanism 11 completes the transfer of the workpiece from the shifting follower component 5. Afterwards, the shifting follower component 5 separates from the workpiece, and another turning tool mechanism 4 performs secondary processing on the workpiece. When the shifting follower component 5 transfers the workpiece to the second spindle mechanism 11, the automatic feeding component 7 starts a new round of workpiece feeding into the outer fixed ring 510 and rotating ring 515. After the second spindle mechanism 11 completes the turning of the workpiece, the shifting follower component 5 clamps and transfers the workpiece while the second spindle mechanism 11 is running. Then, the moving plate 506 drives the fixed ring 510 and the rotating ring 515 to move towards the first spindle mechanism 3. During this process, the drive motor 504 drives the two rotating rings 515 to exchange positions through mechanical transmission. The new workpiece moves towards the first spindle mechanism 3 and is ready for a new round of transfer and loading. The finished workpiece moves towards the feeding screening component 9, and the finished workpiece is automatically unloaded by releasing the clamping of the workpiece in cooperation with the feeding screening component 9. It should be noted that the adjusting motor 501, drive motor 504, and fixed motor 519 mentioned above are all motors with self-locking function; and the balancing block 517 set in the rotating ring 515 can ensure the stability of the overall center of gravity inside the rotating ring 515, avoid the rotating ring 515 from shaking when it moves, and improve the stability of the workpiece during transport; the drive source set in the first spindle mechanism 3 and the second spindle mechanism 11 is a miniature self-locking motor, which, together with the set transmission shaft, can realize the automatic adjustment of the gripper in the chuck.

[0024] Please see Figure 1 , Figure 2 and Figure 6 The automatic feeding component 7 includes: The storage pipe 702 is connected to the top of the assembly plate via the connecting column 703 and is used to store shaft-type workpieces to be processed. The feed pipe 701 is connected to the storage pipe 702, and the feed pipe 701 is set at an angle; An electric push rod 705 is fixedly installed on one side of the outer casing 2. The output end of the electric push rod 705 is connected to a push block 704, which extends into the material storage pipe 702. The cross-section of the push block 704 is circular.

[0025] The specific usage method and working principle are as follows: During feeding, the staff puts the processed parts into the feeding pipe 701 according to the actual situation. The processed parts fall into the storage pipe 702 along the inclined feeding pipe 701. When the rotating ring 515 and the fixed ring 510 approach the storage pipe 702 and the feeding operation is to be performed, the electric push rod 705 drives the processed parts to move towards the port of the storage pipe 702 through the pushing block 704, thereby completing the automated feeding of the processed parts and improving the degree of automation and processing efficiency.

[0026] Please see Figures 1-2 and Figures 7-8 The feeding and screening component 9 includes: The connecting ring 906 is connected to one side of the outer shell 2 by two symmetrically arranged connecting pieces. The connecting ring 906 is provided with a sliding rod 909 that can move adaptively. One end of the sliding rod 909 is connected to a drive wheel 911. Friction texture is provided on the outer periphery of the drive wheel 911. A drive component 908 is provided on one side of the drive wheel 911 for driving the drive wheel 911 to rotate. A storage bin 901 is located below the connecting ring 906. One side of the storage bin 901 is connected to one side of the outer shell 2. A support plate 904 is connected inside the storage bin 901. An opening and closing door 903 is opened on one side of the storage bin 901. The oscillating screen plate 902 is rotatably connected to the storage box 901 at one end. A rotating shaft is rotatably connected to the end of the oscillating screen plate 902 near the support plate 904. Both ends of the rotating shaft are connected to the two sides of the inner wall of the storage box 901. One end of the oscillating screen plate 902 is aligned with the support plate 904. Multiple buffer springs 905 arranged in a linear array are connected to the side of the oscillating screen plate 902 away from the support plate 904. The other end of the buffer springs 905 is connected to the bottom of the inner wall of the storage box 901. Multiple return springs 910 are arranged in a circular array inside the connecting ring 906. The return springs 910 are sleeved on the outer surface of the sliding rod 909. The two ends of the return springs 910 are respectively connected to one side of the drive wheel 911 and the inner side of the connecting ring 906. Multiple limiting plates 907 are arranged in a circular array outside the connecting ring 906. The sliding rod 909 is slidably connected to the connecting ring 906, and the end of the sliding rod 909 away from the drive wheel 911 is connected to the limiting plate 907.

[0027] The specific usage method and working principle are as follows: When the rotating ring 515, in conjunction with the follower clamping block 511, moves the finished workpiece to the direction of the connecting ring 906, the workpiece in the clamping state inside the rotating ring 515 generates a lateral thrust on multiple drive wheels 911. Under the action of the drive wheels 911, this thrust is converted into an axial force on the sliding rod 909, causing the drive wheels 911 to move towards the outer periphery of the connecting ring 906. Under the action of the return spring 910, the workpiece is adaptively clamped. At this time, the fixed motor 519 inside the rotating ring 515 operates, releasing the positioning clamp on the finished workpiece through mechanical transmission. The rotating ring 515 and the fixed ring 510 then move away from the finished workpiece. Afterward, the drive unit 908 drives the drive wheels 911... 11 rotates, and multiple drive wheels 911 move the finished workpiece to one side through friction, causing the workpiece to break free from the clamp formed by the multiple drive wheels 911 and fall into the storage box 901. When the finished workpiece comes into contact with the swing screen plate 902, the finished workpiece generates an impact force on the swing screen plate 902. This impact force is absorbed by the buffer spring 905, thereby reducing the impact damage to the finished workpiece. Due to the hollow design of the swing screen plate 902, the attached debris on the finished workpiece falls below the swing screen plate 902. Due to the inclined setting of the swing screen plate 902, the finished workpiece falls onto the support plate 904, thereby completing the automatic unloading and collection of the finished workpiece and the separation of debris.
