Description

Technical Field

[0001] This invention relates to the field of cutting technology, and in particular to a cutting device for processing automotive parts. Background Technology

[0002] The field of automotive water pipe cutting technology encompasses the design of cutting processes for automotive parts pipes, the development of processing equipment, the design of supporting tooling structures, and the implementation of on-site processing operations. This technology focuses on the processing of pipes used in automotive cooling systems, fuel supply systems, braking systems, and other related systems. Its core focus is on the structural adaptability and operational stability of pipe-to-length cutting operations. This involves the design and coordinated operation of pipe cutting feed structures, pipe clamping and positioning structures, and finished product unloading and collection structures. It is also adapted to the large-scale continuous production mode of automotive parts and represents a sub-branch of automotive parts machining specifically for the forming and processing of pipe-type parts.

[0003] Chinese Patent Publication No. CN220426975U discloses a cutting device for processing automotive parts, including a cutting table, a frame, a cutting machine, a central slit, a recovery bin, a sealing assembly, a compression mechanism, a discharge mechanism, a sliding channel, and a protective cover assembly. The frame and the cutting mechanism form a cutting device and are fixed to the rear side of the upper end of the cutting table. A central slit is opened in the middle of the upper end of the cutting table, located below the cutting wheel of the cutting machine. Two sets of recovery bins are opened in the upper end of the cutting table and are located on the left and right sides of the central slit. A horizontally sliding sealing assembly is installed at the upper opening of the recovery bin. A compression mechanism is set on the front and rear sides of the recovery bin. A discharge mechanism is set at the bottom of the recovery bin. The cutting table has a sliding channel that runs through it. Protective cover assemblies corresponding to the ports of the sliding channel are installed at the front and rear ends of the cutting table. The sliding channel is located below and connected to the central slit. The bottom wall of the sliding channel has a structure that gradually slopes downward from the middle to the front and rear sides.

[0004] Existing technologies use independently set cutting mechanisms to complete pipe cutting operations. The cutting action and the pipe clamping and unloading action are not linked and coordinated. The overall structure of the device is complex, the equipment is difficult to control, there is no stable control structure for the cutting feed process, which is prone to feed impact, causing saw blade breakage, and the cutting path is prone to wobble. The timing of the clamping structure and the cutting action cannot be matched, which can easily lead to the pipe being clamped in a timely manner, causing the pipe to shift and deviate during the cutting process, resulting in cutting defects. The unloading action and the cutting completion point cannot be synchronized, which can easily lead to the finished pipe being stuck, affecting the efficiency of continuous processing operations of the device.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention uses a U-shaped bracket in the water pipe cutting structure to provide stable mounting support for the transmission and execution components. A servo motor drives a bidirectional screw to rotate, causing the drive slider and connecting rod to move synchronously. This achieves uniform and controllable feed speed for the cutting components, avoiding feed impact, reducing the risk of saw blade breakage, and ensuring a stable cutting path. The sliding rod of the cutting components restricts the movement trajectory, improving feed stability. A shield isolates metal debris and spatter, protecting the equipment's transmission structure and operator safety.

[0017] 2. This invention provides a falling channel for finished pipes and metal scraps through the material clamping structure's discharge port. A sliding groove guides and limits the movement of the clamping drive components. A U-shaped sliding plate with a limiting block ensures smooth and stable linkage. A baffle restricts the downward stroke and prevents material splashing. A drive protrusion drives the clamping components to switch action states. A fixed plate with a limiting rod provides stable support for the arc-shaped plate. The elastic clamping plate adapts to pipes of different outer diameters, preventing damage to the pipe surface. The push-pull rod's staggered extension and retraction drives the arc-shaped plate to rotate and complete unloading. The invention eliminates the need for an independent drive source, simplifying the device structure, ensuring precise timing of actions, and improving processing stability and finished product quality.

[0018] 3. This invention provides initial relaxation space for the clamping components through the initial platform of the driving protrusion, ensuring smooth pipe feeding operations. With the synchronous drive of protrusions two and three, the upper and lower arc rods move, causing the push-pull rods to extend synchronously to complete the stable clamping and fixing of the pipe. Through the cooperation of protrusion one and the groove, the upper and lower arc rods slide along the corresponding paths, causing the push-pull rods to extend and retract in a staggered manner to achieve the unloading action. The smooth slopes between each path ensure smooth and uninterrupted operation. The matching design of the spacing between the protrusions and the arc rods ensures the precise timing of the clamping and unloading actions, improving the reliability of the device operation and the stability of processing.

[0021] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0022] A cutting device for machining automotive parts, see reference. Figure 1 , Figure 2 and Figure 3 The device includes a support platform 1, which provides a stable installation foundation and working platform for the entire device. A shell 3 is fixedly installed on the upper part of the support platform 1. The shell 3 can protect the internal working structure of the device, isolate the splashes generated during processing, and reduce the noise diffusion during operation. A collection cabinet 2 is fixedly installed on the lower part of the support platform 1. The collection cabinet 2 can receive the finished pipe and the metal shavings generated during the cutting operation. A relay support 5 is fixedly connected to the front of the upper part of the support platform 1 to guide the pipe into the process. The relay support 5 can support and guide the pipe to be processed, so that the pipe can enter the processing position smoothly and steadily, and avoid the pipe sagging or deviation during the feeding process. The upper middle part of the support platform 1 is equipped with a water pipe cutting structure 4 for cutting pipes. The water pipe cutting structure 4 is the core execution structure for pipe cutting operations and can complete the pipe cutting operation. The upper rear part of the support platform 1 is equipped with a material clamping structure 6 for clamping the front auxiliary water pipe cutting structure 4 for cutting. The material clamping structure 6 can clamp and fix the pipe to be cut, and can also complete the unloading operation of the finished pipe after cutting. The material clamping structure 6 includes a clamping drive component 61 located at the rear of the upper end of the support platform 1. The clamping drive component 61 is fixedly connected to the water pipe cutting structure 4 and moves up and down synchronously with the water pipe cutting structure 4. The clamping drive component 61 can move synchronously with the feeding and resetting actions of the water pipe cutting structure 4, providing driving force for the action of the clamping component 62. The rear of the upper end of the support platform 1 is provided with a clamping component 62 for clamping the pipe. The clamping component 62 is located inside the clamping drive component 61 and moves synchronously with the up and down movement of the clamping drive component 61. Under the drive of the clamping drive component 61, the clamping component 62 can sequentially complete the actions of clamping and fixing the pipe and unloading the finished product.

[0023] For further details, please refer to [link / reference]. Figure 3 The inner surface of the collection cabinet 2 is slidably connected to a drawer cabinet 21 for receiving finished materials. The drawer cabinet 21 can receive finished pipes and metal scraps falling from the discharge port 63, realizing the simultaneous collection of finished products and waste materials. The drawer cabinet 21 adopts a sliding installation method, which makes it easy for operators to pull it out of the collection cabinet 2 to complete the centralized transfer of finished pipes and the cleaning of metal scraps, avoiding the scattering of metal scraps to the processing site and reducing the subsequent on-site cleaning workload.

[0024] In the operation of this embodiment, the timing of the entire process of pipe cutting, clamping, and unloading is matched through the cooperation of the water pipe cutting structure 4 and the material clamping structure 6. The feeding action of the water pipe cutting structure 4 drives the clamping drive component 61 of the material clamping structure 6 to move synchronously through the connecting block 454, which simplifies the overall structure of the device, reduces the manufacturing cost and control complexity of the equipment. The clamping component 62 of the material clamping structure 6 completes the clamping and fixing of the pipe before the cutting operation, which avoids the pipe from shifting or deviating during the cutting process, ensures the stability of the cutting operation, and reduces processing defects such as skewed cuts and excessive burrs. After the cutting is completed, the unloading action is completed simultaneously to prevent the finished pipe from remaining at the processing station, thereby improving the efficiency of continuous processing and the quality of finished products.

[0025] Example 2, based on Example 1, uses the U-shaped bracket 41 of the water pipe cutting structure 4 to provide stable mounting support for the transmission and execution components. The servo motor 42 drives the bidirectional screw 43 to rotate, causing the drive slider 44 and connecting rod 46 to move synchronously. This achieves uniform and controllable feed speed for the cutting component 45, avoiding feed impact, reducing the risk of saw blade 455 chipping, and ensuring a stable cutting path. The sliding rod 451 of the cutting component 45 restricts the movement trajectory, improving feed stability. The shield 453 isolates metal debris and spatter, protecting the equipment's transmission structure and operator safety. The connecting block 454 links the cutting and clamping actions, simplifying the overall device structure, reducing manufacturing costs and control complexity, and ensuring perfect timing of actions.

[0026] For further details, please refer to [link / reference]. Figure 4The water pipe cutting structure 4 includes a U-shaped bracket 41 fixedly installed at the middle of the upper end of the support platform 1. The U-shaped bracket 41 provides stable installation support for all transmission and execution components of the water pipe cutting structure 4. A cutting component 45 for cutting pipes is slidably connected to the inner surface of the horizontal part of the U-shaped bracket 41. The cutting component 45 can complete the up-and-down feeding and resetting actions along the inner wall of the U-shaped bracket 41. A bidirectional screw 43 is rotatably installed on the inner surface of the horizontal part of the U-shaped bracket 41. The outer surface of the bidirectional screw 43 is provided with two sets of threaded grooves with opposite directions of rotation. During rotation, it can synchronously drive the corresponding components on both sides to complete the sliding actions in opposite directions. Both sides of the bidirectional screw 43 are threadedly connected to drive sliders 44 that are slidably connected to the inner wall of the U-shaped bracket 41. The two drive sliders 44 can move along the U-shaped bracket 41 under the rotation drive of the bidirectional screw 43. The inner wall of the cutting component 45 slides synchronously towards or away from each other. The lower end of the drive slider 44 is rotatably connected to a connecting rod 46 that is rotatably connected to the cutting component 45. The connecting rod 46 can convert the horizontal sliding motion of the drive slider 44 into the vertical up-and-down motion of the cutting component 45. A servo motor 42 that drives the bidirectional screw 43 to rotate is fixedly installed on the inner wall of the U-shaped bracket 41. The servo motor 42 can output stable rotational power and control the rotation direction and speed of the bidirectional screw 43, thereby controlling the feed speed and feed stroke of the cutting component 45. The feed structure formed by the bidirectional screw 43 and the connecting rod 46 can keep the feed speed of the cutting component 45 uniform and controllable, avoid the feed impact problem that is prone to occur in traditional direct drive structures, reduce the risk of saw blade 455 chipping, extend the service life of the tool, and at the same time ensure the stability of the cutting path and avoid the problem of cutting deviation.

[0027] For further details, please refer to [link / reference]. Figure 5The cutting component 45 includes a drive motor 452 mounted on the upper side of the U-shaped bracket 41. The drive motor 452 provides power for the rotary cutting operation of the saw blade 455. The lower end of the drive motor 452 is symmetrically connected to sliding rods 451 that slide along the inner wall of the U-shaped bracket 41. The sliding rods 451 can move synchronously up and down with the drive motor 452 and slide along the inner wall of the U-shaped bracket 41, thus limiting the overall movement trajectory of the cutting component 45 and improving its stability during up and down movement. The lower ends of the two sliding rods 451 are jointly connected to shielding covers 453 that are rotatably connected to connecting rods 46 on both sides. The shielding covers 453 can move up and down and reset with the connecting rods 46, while also protecting the saw blade 455 by covering it and isolating it from metal chips and spatter generated during the cutting process. The transmission structure of the device causes jamming and wear, while protecting the safety of on-site operators. A saw blade 455 is rotatably mounted on the inner surface of the shield 453 and is connected to the drive motor 452 via a chain belt installed inside one of the sliding rods 451. The saw blade 455 can rotate at high speed under the drive of the drive motor 452 to cut and sever the pipe. A connecting block 454 is fixedly connected to the rear end of the shield 453 and is fixedly connected to the material clamping structure 6. The connecting block 454 can fix the cutting component 45 and the clamping drive component 61, so that the clamping drive component 61 can move synchronously with the up and down movement of the cutting component 45. There is no need to set an independent drive source for the clamping action, which simplifies the overall structure of the device, reduces the manufacturing cost and control complexity of the equipment, and ensures that the timing of the clamping action and the cutting feed action are perfectly matched.

[0028] In Example 3, based on Example 2, the material clamping structure 6 provides a falling channel for finished pipes and metal scraps through the discharge port 63. The sliding groove 64 guides and limits the movement of the clamping drive component 61. The U-shaped sliding plate 614, together with the limiting block 611, ensures smooth and stable linkage. The baffle 612 limits the downward stroke and prevents material splashing. The drive protrusion 613 drives the clamping component 62 to complete the switching of action state. The fixed plate 621, together with the limiting rod 623, provides stable support for the arc plate 622. The elastic clamping plate 624 adapts to pipes of different outer diameters to avoid clamping damage to the pipe surface. The push-pull rod 628 extends and retracts in a staggered manner to drive the arc plate 622 to rotate and complete the unloading. The absence of an independent drive source simplifies the device structure, ensures precise matching of action timing, and improves processing stability and finished product quality.

[0029] For further details, please refer to [link / reference]. Figure 6The material clamping structure 6 also includes a discharge port 63 located at the rear of the upper end of the support platform 1. The discharge port 63 provides a channel for finished pipes and metal scraps to fall. The discharge port 63 is connected to the inner cavity of the collection cabinet 2, so that the finished pipes and metal scraps falling through the discharge port 63 can directly enter the interior of the collection cabinet 2 for collection. The upper end of the support platform 1 is symmetrically provided with sliding grooves 64 along the central axis of the discharge port 63. The sliding grooves 64 can provide guidance and limit for the up and down movement of the clamping drive component 61. The clamping drive component 61 is slidably connected to the inner surface of the sliding grooves 64 on both sides, so that the clamping drive component 61 can complete stable up and down sliding along the path of the sliding grooves 64, avoiding deviation or jamming during the linkage action. The clamping components 62 are symmetrically distributed along the central axis of the discharge port 63. The two sets of symmetrically arranged clamping components 62 can simultaneously complete the clamping and fixing operation from both sides of the pipe, so that the clamping force on the pipe is evenly distributed, avoiding the pipe from shifting during the clamping process.

[0030] For further details, please refer to [link / reference]. Figure 7 The clamping drive component 61 includes a U-shaped sliding plate 614, which serves as the main supporting structure of the clamping drive component 61 and can drive the corresponding component to move up and down synchronously. A limiting block 611 is symmetrically and fixedly connected to the outer surface of the U-shaped sliding plate 614 and slidably connected to the inner surface of the slide groove 64. The limiting block 611 can be embedded inside the slide groove 64 and slide along the path of the slide groove 64, limiting the movement trajectory of the U-shaped sliding plate 614 and ensuring the stability of the U-shaped sliding plate 614 during its up and down movement. A baffle 612 is symmetrically and fixedly connected to the lower end of the U-shaped sliding plate 614. The baffle 612 can limit the downward stroke of the U-shaped sliding plate 614 to prevent the U-shaped sliding plate 614 from moving downwards. If the sliding plate 614 overtravels during its descent, it can also laterally block falling metal debris and finished pipes to prevent material from splashing. The inner wall of the U-shaped sliding plate 614 is symmetrically provided with driving protrusions 613 for switching the state of the clamping component 62. The driving protrusions 613 can move up and down synchronously with the U-shaped sliding plate 614, and drive the clamping component 62 to complete the corresponding action switching through its own structural path. The upper end of the U-shaped sliding plate 614 is fixedly connected to the connecting block 454, so that the U-shaped sliding plate 614 can be fixedly connected to the cutting component 45 through the connecting block 454, and move up and down synchronously with the feeding and resetting actions of the cutting component 45.

[0031] For further details, please refer to [link / reference]. Figure 8 and Figure 9The clamping component 62 includes a fixed plate 621 fixedly connected to the upper end of the support platform 1. The fixed plate 621 provides a stable mounting base for all moving parts of the clamping component 62. A limit rod 623 is slidably connected to the inner wall of the fixed plate 621. The limit rod 623 can slide horizontally along the inner wall of the fixed plate 621, providing guidance and support for the translational movement of the arc-shaped plate 622. The arc-shaped plate 622 is rotatably connected to the side of the limit rod 623 near the discharge port 63. The arc-shaped plate 622 can synchronously complete horizontal translation with the limit rod 623, and can also rotate along the axis of the limit rod 623. The upper and lower ends of the arc-shaped plate 622 are symmetrically connected to elastic clamping plates 624 driven by torsion springs. The elastic clamping plates 624, driven by the torsion springs, can adaptively conform to the outer walls of pipes with different outer diameters, expanding the applicable processing range of the device. Simultaneously, the buffering effect of the torsion springs prevents excessive clamping force from damaging the pipe surface. The outer surface of the arc-shaped plate 622 is symmetrically connected to push-pull rods 628. The push-pull rods 628 can drive the arc-shaped plate 622 to complete horizontal translation, and can also drive the arc-shaped plate 622 to complete rotation through their own position changes. The sides of both push-pull rods 628 furthest from the arc-shaped plate 622 are both through-holes. A fixed plate 621 is fixedly connected to a limiting plate 625. The limiting plate 625 can drive the push-pull rod 628 to complete the horizontal extension and retraction action, and at the same time limit the extension and retraction stroke of the push-pull rod 628. Compression springs 627, which are fixedly connected to the fixed plate 621, are fixedly connected to the side of each limiting plate 625 near the arc-shaped plate 622. The compression springs 627 can be compressed and store elastic force when the limiting plate 625 moves towards the pipe. Simultaneously, when the external driving force disappears, their own rebound force can drive the limiting plate 625 and the push-pull rod 628 to complete the reset action. When the positions of the upper and lower push-pull rods 628 change... When misaligned, the arc plate 622 rotates along the axis of the limiting rod 623. The misaligned extension and retraction of the upper and lower push-pull rods 628 can drive the arc plate 622 to complete the rotation. Then, the elastic clamping plate 624 presses the cut finished pipe downward to complete the unloading action. There is no need to set up an additional independent unloading drive mechanism, which simplifies the device structure and reduces the maintenance difficulty and failure rate of the equipment. At the same time, the unloading action can be connected synchronously with the node where the cutting is completed, avoiding the finished pipe from staying at the processing station and affecting subsequent continuous processing operations. The rotational unloading method can also avoid the finished pipe from rubbing against the processing station, protecting the processing surface of the finished pipe.

[0032] In Example 4, based on Example 3, the initial platform 6133 of the driving protrusion 613 provides initial relaxation space for the clamping component 62, ensuring smooth pipe feeding. Protrusions 6132 and 6135 simultaneously drive the upper and lower arc-shaped rods 626 to move, causing the push-pull rod 628 to extend synchronously and complete the stable clamping and fixing of the pipe. Through the cooperation of protrusion 6131 and the slot 6134, the upper and lower arc-shaped rods 626 slide along corresponding paths, causing the push-pull rod 628 to extend and retract in a staggered manner to achieve unloading. The smooth ramps between each path ensure smooth, uninterrupted operation. The matching design of the spacing between the protrusions and the arc-shaped rods 626 ensures precise timing of clamping and unloading actions, improving the reliability of the device and the stability of processing.

[0033] For further details, please refer to [link / reference]. Figure 8 and Figure 9The driving protrusion 613 includes an initial platform 6133 flush with the inner wall of the U-shaped sliding plate 614. The initial platform 6133 is the resting position of the arc rod 626 when the clamping component 62 is in the initial relaxed state, which can ensure that the clamping component 62 remains relaxed when the device is in the initial state, providing sufficient space for the feeding operation of the pipe. A protrusion three 6135 is fixedly connected to the middle of the inner wall of the U-shaped sliding plate 614. The protrusion three 6135 can drive the lower arc rod 626 to move towards the pipe, thereby driving the lower push-pull rod 628 to extend. The middle of the inner wall of the U-shaped sliding plate 614 is aligned with the protrusion three 6135. A second protrusion 6132 is fixedly connected to the upper part of the U-shaped sliding plate 614. The second protrusion 6132 can drive the upper arc-shaped rod 626 to move towards the pipe, thereby driving the upper push-pull rod 628 to extend. A slot 6134 is provided on the upper part of the inner wall of the U-shaped sliding plate 614. The slot 6134 provides space for the lower arc-shaped rod 626 to return to its original position. When the lower arc-shaped rod 626 moves to the position of the slot 6134, it can return to its original position under the rebound force of the compression spring 627. A first protrusion 6131 is symmetrically fixedly connected to the upper part of the inner surface of the U-shaped sliding plate 614 along the slot 6134. The first protrusion 6131 can drive the upper part... The arc-shaped rod 626 moves further towards the pipe, causing the upper push-pull rod 628 to extend further. The distances between the initial platform 6133 and the second protrusion 6132, and between the first protrusion 6131 and the arc-shaped plate 622 decrease sequentially and are connected to each other by a smooth ramp. The smooth ramp transition allows the arc-shaped rod 626 to remain stable when sliding between different paths, avoiding jamming or impact, and ensuring the smoothness of clamping and unloading actions. The initial platform 6133, the slot 6134, and the arc-shaped plate 622 are at the same distance, so that when the lower arc-shaped rod 626 moves to the position of the slot 6134, it can return to the same horizontal position as the initial state. After the reset action is completed, protrusion 3 6135 and protrusion 2 6132 become flush, allowing the arc-shaped rods 626 on both sides to move synchronously towards the pipe under the drive of protrusion 2 6132 and protrusion 3 6135. This drives the two push-pull rods 628 to extend synchronously, achieving smooth translation of the arc-shaped plate 622 and completing the clamping and fixing action of the pipe. The initial platform 6133, protrusion 3 6135, and groove 6134 are connected to each other by a smooth ramp, allowing the lower arc-shaped rod 626 to smoothly slide and switch between the initial platform 6133, protrusion 3 6135, and groove 6134, ensuring accurate connection of the action sequence.

[0034] For further details, please refer to [link / reference]. Figure 9Two arc-shaped rods 626 are fixedly connected to the end of the upper limiting plate 625 away from the arc-shaped plate 622. The two arc-shaped rods 626 can move horizontally synchronously with the upper limiting plate 625, and can also slide along the corresponding path of the driving protrusion 613, providing driving force for the movement of the upper limiting plate 625. An arc-shaped rod 626 is fixedly connected to the end of the lower limiting plate 625 away from the arc-shaped plate 622. The arc-shaped rod 626 can move horizontally synchronously with the lower limiting plate 625, and can also slide along the corresponding path of the driving protrusion 613, providing driving force for the movement of the lower limiting plate 625. The two arc-shaped rods 626 at the top slide along the path formed by the initial platform 6133, protrusion 2 6132, and protrusion 1 6131, so that the arc-shaped rods 626 at the top can slide along the path formed by the initial platform 6133, protrusion 2 6132, and protrusion 1 6131 as the U-shaped sliding plate 614 moves downward, sequentially along the path formed by the initial platform 6133, protrusion 2 6132, and protrusion 1 6131. 6132. Protrusion 6131 slides, gradually pushing the upper limiting plate 625 towards the pipe, causing the upper push-pull rod 628 to extend and further extend. The lower arc rod 626 slides along the path formed by the initial platform 6133, protrusion 6135, and groove 6134, allowing the lower arc rod 626 to slide along the initial platform 6133, protrusion 6135, and groove 6134 in sequence as the U-shaped sliding plate 614 moves downward. First, it pushes the lower limiting plate 625 towards the pipe, causing the lower push-pull rod 628 to extend. Then, it resets when it reaches the groove 6134, causing the lower push-pull rod 628 to retract. By sliding along different paths of the upper and lower arc rods 626, the timing of clamping and unloading actions is switched, ensuring that the clamping action is completed before the cutting action, and the unloading action is performed after the pipe is completely cut.

[0035] Furthermore, the distance between the starting heights of protrusion 2 6132 and protrusion 3 6135 is the same as the distance between the upper and lower arc-shaped rods 626, allowing the upper and lower arc-shaped rods 626 to simultaneously contact the starting positions of protrusion 2 6132 and protrusion 3 6135. This synchronously pushes the upper and lower limiting plates 625 towards the pipe, causing the upper and lower push-pull rods 628 to extend synchronously, ensuring that the arc-shaped plate 622 can smoothly move towards the pipe, completing the clamping and fixing action of the pipe. Protrusion 1 6131 The distance between the starting height and the starting height of the slot 6134 is the same as the distance between the upper and lower arc rods 626. This allows the lower arc rod 626 to simultaneously contact the starting position of the slot 6134 when the upper arc rod 626 contacts the starting position of the protrusion 6131. ​​This enables the upper push-pull rod 628 to extend further and the lower push-pull rod 628 to retract synchronously, causing the upper and lower push-pull rods 628 to be misaligned. This drives the arc plate 622 to complete the rotation and unloading action, ensuring the accurate execution of the unloading action.
