Description

Technical Field

[0001] This invention relates to the field of magnetic valve processing technology, and in particular to a magnetic pump valve housing cutting device. Background Technology

[0002] Existing magnetic pump valves have complex housing structures, often featuring irregular curved surfaces and multiple connection ports. To facilitate subsequent welding and assembly processes, high-precision cutting is frequently required, such as creating holes, windows, or cutting to a fixed length. This process demands high standards for cut quality, dimensional accuracy, and processing efficiency.

[0003] Currently, the processing of such irregularly shaped thin-walled parts generally faces the following technical challenges: First, clamping is difficult and prone to deformation: Traditional general-purpose fixtures are difficult to adapt to the irregular shape of the shell, and it is not easy to accurately find the positioning reference during clamping, resulting in long auxiliary time. If radial clamping is used, the thin-walled shell is easily deformed by excessive or uneven clamping force, which seriously affects the processing accuracy. Second, processing stability and quality are difficult to guarantee: During the cutting process, especially under high-energy methods such as laser or plasma cutting, the thin-walled shell is prone to micro-vibration due to uneven heating or cutting force. This can lead to burrs, vibration marks, or even micro-cracks on the cut, reducing structural strength and increasing the workload of subsequent cleaning. Third, the process is fragmented and the degree of automation is low: From clamping, cutting, deburring to unloading and chip removal, each step is mostly operated manually or completed by multiple independent machines. The process flow is fragmented, the overall efficiency is low, and consistency is difficult to guarantee, which has become a bottleneck for mass production. Summary of the Invention

[0004] The purpose of this invention is to solve the problems existing in the prior art, and to propose a magnetic pump valve housing cutting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A magnetic pump valve housing cutting device, including a cabinet, and further comprising:

[0007] The upright plate is provided in two sets and is respectively arranged on both sides of the cabinet. Each upright plate is provided with a clamping part and a drive motor for driving the clamping part to rotate is provided on the upright plate.

[0008] A robotic arm is mounted on one side of the cabinet via a support plate, and the end of the robotic arm is provided with a processing part for processing the housing.

[0009] And a waste trough, which is located inside the cabinet and between two clamping parts, for collecting waste generated when the processing part processes the housing;

[0010] The waste trough is equipped with a filter screen at the top.

[0011] Preferably, the clamping part includes a rotating seat rotatably mounted on the upright plate, a hydraulic cylinder fixedly connected to the rotating seat, and a clamping seat fixedly connected to the piston rod of the hydraulic cylinder, wherein the clamping seat moves against the shell to be processed.

[0012] Preferably, the clamping seat includes an end plate fixedly connected to the piston rod of the hydraulic cylinder, a support plate fixedly connected to the end plate via a connecting rod, a slide rod slidably connected to the support plate, a force-bearing plate and a movable plate respectively disposed at both ends of the slide rod, and a first elastic element sleeved on the outside of the slide rod and connected at both ends to the support plate and the movable plate respectively, wherein a rubber pad is provided on the outer wall of the force-bearing plate.

[0013] Preferably, the clamping base is further provided with an auxiliary clamping assembly, which includes a force-bearing rod that is circumferentially and uniformly rotated on the movable plate, a swing rod hinged to the end of the force-bearing rod away from the movable plate, a fixed rod that is fixedly connected to the support plate and rotatably connected to the swing rod through a pin, and an elastic telescopic plate fixedly disposed at the end of the swing rod away from the force-bearing rod. The end of the elastic telescopic plate is provided with an abutment member that moves against the shell to be processed.

[0014] Preferably, the abutting member includes a V-shaped plate rotatably mounted on the telescopic end of the elastic telescopic plate via a rotating shaft. A torsion spring for driving the V-shaped plate to return to its original rotation is mounted on the rotating shaft. Rollers are rotatably mounted on both ends of the V-shaped plate away from the rotating shaft, and rubber sleeves are fitted on the outer sides of the rollers.

[0015] Preferably, the support plate is connected to a locking assembly that locks the length of the elastic telescopic plate synchronously with the movement of the force plate. The locking assembly includes a movable rod slidably connected to the support plate, limiting plates respectively disposed at both ends of the movable rod, a second elastic element sleeved on the outside of the movable rod and connected at both ends to the support plate and one of the limiting plates respectively, a traction rope fixedly connected to the movable rod, a locking plate fixedly connected to the end of the traction rope away from the movable rod, an elastic telescopic rod disposed on the outer wall of the locking plate and the fixed end of the elastic telescopic plate, and a plurality of elastic telescopic inserts disposed on the locking plate. The outer wall of the telescopic end of the elastic telescopic plate is provided with a plurality of insertion holes that cooperate with the elastic telescopic inserts, and the limiting plate near the force plate moves against the force plate.

[0016] Preferably, the end of the traction rope furthest from the moving rod passes sequentially through the fixed end of the fixed rod, the swing rod, and the elastic telescopic plate, and is finally fixedly connected to the locking plate.

[0017] Preferably, the support plate, the fixed rod, the swing rod, and the elastic telescopic plate are all provided with guide frames that cooperate with the traction rope.

[0018] Preferably, the processing unit includes a rotating shaft rotatably disposed at the end of the robotic arm, a rotating plate fixedly connected to the rotating shaft, a laser head disposed at one end of the rotating plate, and a polishing brush disposed at the other end of the rotating plate and driven by a motor.

[0019] Preferably, the filter screen includes an elastic arc-shaped filter screen and sliders disposed on both sides of the arc-shaped filter screen. The top inner wall of the waste trough is provided with a groove for the slider to slide, and a third elastic element is disposed between the inner wall of the groove and the slider.

[0020] The arc-shaped filter is higher in the middle and lower on both sides.

[0021] Compared with the prior art, the present invention provides a magnetic pump valve housing cutting device, which has the following beneficial effects:

[0022] 1. In this invention, the combination of a multi-link mechanism and an elastic telescopic plate achieves adaptive enveloping clamping of irregular shells. During clamping, multiple abutment parts can independently extend and retract under the action of elastic elements, closely fitting the concave and convex surfaces of the workpiece, avoiding deformation caused by concentrated stress and hard impacts. After clamping, the traction rope-locking plate linkage mechanism is automatically triggered, mechanically locking the length of the elastic telescopic plate, instantly transforming the entire clamping system from a flexible adaptive state to a rigid frame state. This not only solves the problem of unstable gripping of irregular parts, but also provides vibration-resistant rigidity for subsequent rotation and cutting processes, fundamentally ensuring the stability of high-precision machining and the quality of the cut. It is suitable for vibration-sensitive processes such as laser cutting.

[0023] 2. In this invention, by integrating a rotatable composite processing head at the end of the robotic arm, laser cutting and grinding functions are integrated into one. After cutting, there is no need to disassemble the workpiece or change the machine tool. Simply drive the rotating plate to rotate, and the grinding brush can be switched to the working position to perform online deburring on the newly generated cutting edge. Continuous operation under the same equipment, fixture, and coordinate reference eliminates the positioning error caused by secondary clamping, ensuring the accuracy and consistency of burr cleaning. It significantly shortens the flow time and labor cost of cutting-transfer-grinding in traditional processes, and realizes a highly efficient and high-quality automated precision machining process.

[0024] 3. In this invention, the axial clamping force is converted into a lock on the lateral clamping unit through mechanical linkage. When the force plate and the limiting plate are fully in contact, that is, when the axial clamping force is up to standard, the locking plate is driven by the moving rod, traction rope and other mechanisms to fix the retracted elastic telescopic plate with multiple pins. This locking action is triggered entirely by the main clamping action, without the need for additional sensors or control, ensuring the necessary correlation between the clamping force and the locking state. This effectively prevents the clamping from loosening under the action of processing vibration or workpiece rotation centrifugal force, and greatly improves the safety of long-term, high-load processing.

[0025] 4. In this invention, by designing a composite waste trough with an elastic filter screen, the arc-shaped filter screen can not only effectively intercept large pieces of waste and splashes generated during cutting, facilitating sorting and cleaning, but also form a passive safety barrier. In extreme situations such as accidental workpiece falls, the arc-shaped filter screen can absorb and buffer the huge impact kinetic energy through its own elastic deformation and the action of the sliders at both ends compressing the third elastic element in the trough, converting the impact force into elastic potential energy and releasing it smoothly. This effectively prevents the workpiece from directly falling and damaging the structure below or the waste trough, and also prevents flying fragments from injuring people. While realizing automatic waste collection, it significantly enhances the overall operational safety and durability of the equipment. Attached Figure Description

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0040] like Figures 1 to 3 As shown, this embodiment proposes a magnetic pump valve housing cutting device, including a cabinet 1, and further comprising:

[0041] The upright plate 2 is provided in two sets and is respectively located on both sides of the cabinet 1. Each upright plate 2 is provided with a clamping part 3 and a drive motor 8 for driving the clamping part 3 to rotate is provided on the upright plate 2.

[0042] Robotic arm 4 is mounted on one side of cabinet 1 via a support plate, and a processing part 5 for processing the housing is provided at the end of the robotic arm 4.

[0043] And a waste trough 6, which is located inside the cabinet 1 and between two clamping parts 3, for receiving waste chips generated when the processing part 5 processes the housing;

[0044] The waste trough 6 is equipped with a filter screen 7 at the top;

[0045] Specifically, the operator places the magnetic pump valve housing to be cut between the two clamping parts 3, and then controls the clamping parts 3 to reliably clamp and fix the workpiece from both ends. Depending on the processing requirements, one or both drive motors 8 are activated to drive the clamped housing to rotate around its axis, accurately rotating the area to be cut to face the robotic arm 4 and processing unit 5. The robotic arm 4 is programmed or manually controlled to precisely move the processing unit 5 to the target processing starting point. The processing unit 5 is then activated, such as with a laser, and the robotic arm 4 is controlled to move along a predetermined trajectory to complete the cutting operation on the workpiece. During the cutting process... All waste, sparks, slag, etc. generated fall downwards under gravity. After initial screening by the top filter screen 7, they finally fall into the waste trough 6 below for centralized collection, keeping the work area clean. After processing is completed, the processing unit 5 stops working and resets. The drive motor 8 can rotate the workpiece back to an angle that is easy to remove. Finally, the clamping part 3 is released, and the processed workpiece is removed. The operator only needs to complete the loading and unloading and start the program. The execution of the processing trajectory and the adjustment of the workpiece position can be completed automatically, which reduces the skill requirements of the operator, improves the automation level and repeatability of the production process, and is suitable for mass production.

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 9 As shown, in a preferred embodiment, based on the above method, the clamping part 3 further includes a rotating seat 301 rotatably mounted on the upright plate 2, a hydraulic cylinder 302 fixedly connected to the rotating seat 301, and a clamping seat 303 fixedly connected to the piston rod of the hydraulic cylinder 302. The clamping seat 303 moves against the shell to be processed.

[0047] Furthermore, the clamping seat 303 includes an end plate 3031 fixedly connected to the piston rod of the hydraulic cylinder 302, a support plate 3032 fixedly connected to the end plate 3031 via a connecting rod, a slide rod 3033 slidably connected to the support plate 3032, a force-bearing plate 3034 and a movable plate 3035 respectively disposed at both ends of the slide rod 3033, and a first elastic element 3036 sleeved on the outside of the slide rod 3033 and connected at both ends to the support plate 3032 and the movable plate 3035 respectively. The outer wall of the force-bearing plate 3034 is provided with a rubber pad.

[0048] Furthermore, the clamping base 303 is also provided with an auxiliary clamping assembly, which includes a force-bearing rod 9 that is circumferentially and uniformly rotated on the movable plate 3035, a swing rod 901 hinged to the end of the force-bearing rod 9 away from the movable plate 3035, a fixed rod 902 that is fixedly connected to the support plate 3032 and rotatably connected to the swing rod 901 through a pin, and an elastic telescopic plate 903 fixedly disposed at the end of the swing rod 901 away from the force-bearing rod 9. The end of the elastic telescopic plate 903 is provided with an abutment member that moves against the shell to be processed.

[0049] Specifically, when the hydraulic cylinder 302 extends and pushes the entire clamping seat 303 towards the workpiece, the clamping seat 303 moves forward as a whole, and the force plate 3034 first contacts the end face of the workpiece. As the cylinder continues to apply force, the reaction force of the workpiece on the force plate 3034 will push the slide rod 3033, causing it to overcome the elastic force of the first elastic element 3036 and slide relative to the support plate 3032 towards the movable plate 3035. This process buffers rigid impact, which is beneficial to protecting the housing of the thin-walled or high-precision magnetic pump valve and preventing indentations or deformation during the clamping stage. While the slide rod 3033 slides relative to the support plate 3032, the movable plate 3035, which is fixed to the slide rod 3033, also moves in the same direction. The movable plate 3035 pushes the circumferentially distributed force rods 9 to move together, thereby driving the swing rod 901 to rotate with its hinge point with the fixed rod 902 as the fulcrum. The rotation of the swing rod 901 drives the elastic telescopic plate 903 at its end towards the central axis of the workpiece. Extending radially, the abutment members at the ends of each elastic telescopic plate 903 contact the irregular outer circumferential surface of the workpiece. Due to the telescopic compensation function of the elastic telescopic plate 903 itself, each abutment member can independently adjust its extension length according to the specific position of the contacting workpiece surface, ensuring that all abutment members can fit tightly and evenly against the outer wall of the workpiece, forming radial auxiliary clamping. When the hydraulic system pressure reaches the set value, the clamping action is completed. At this time, the workpiece is stably clamped by the axial force plate 3034 and multiple radial abutment members. The combination of axial end face pressing and multi-point radial envelope clamping increases the clamping contact area and friction, effectively limiting the radial movement and rotation of the workpiece that may occur when it is subjected to cutting force. The clamping stability and rigidity are significantly better than single axial clamping. The entire buffering and radial clamping action is driven by the linear motion of a single hydraulic cylinder 302, without the need for an additional power source, simplifying the control system and improving the reliability of the mechanism.

[0050] like Figure 4 , Figure 6 and Figure 9As shown, in a preferred embodiment, based on the above method, the abutting member further includes a V-shaped plate 10 rotatably disposed at the telescopic end of the elastic telescopic plate 903 via a rotating shaft. A torsion spring for driving the V-shaped plate 10 to reset and rotate is disposed on the rotating shaft. Rollers 1001 are rotatably disposed at both ends of the V-shaped plate 10 away from the rotating shaft. A rubber sleeve is sleeved on the outer side of the roller 1001.

[0051] Specifically, when the elastic telescopic plate 903 drives the abutment member to extend radially towards the workpiece, the two rollers 1001 on the V-shaped plate 10 will first contact the outer wall surface of the workpiece. Since the outer wall of the workpiece may have an inclined surface, curved surface, or irregular shape, the contact point heights of the two rollers 1001 may be different. At this time, the V-shaped plate 10 can overcome the torque of the torsion spring and rotate slightly around its axis. The structure of the V-shaped plate 10 naturally forms two separate contact points when contacting the workpiece, thus enabling both rollers 1001 to achieve effective contact with the workpiece surface, automatically... By adapting to the local contour of the workpiece at the contact point, the abutment can better adapt to the local irregularities of the workpiece surface and form a more stable constraint in the local area. Compared with a single spherical or planar contact point, this design provides better resistance to torsion and lateral sliding, making radial auxiliary clamping more reliable. When the V-shaped plate 10 is subjected to force and swings to adjust the processing posture, the roller 1001 and the outer wall of the workpiece experience rolling friction rather than sliding friction, which greatly reduces the frictional resistance and heat generated by the adjustment and avoids scratches or abrasions on the workpiece surface.

[0052] like Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in a preferred embodiment, based on the above method, a locking assembly is further connected to the support plate 3032, which locks the length of the elastic telescopic plate 903 synchronously with the movement of the force plate 3034. The locking assembly includes a movable rod 11 slidably connected to the support plate 3032, limiting plates 111 respectively disposed at both ends of the movable rod 11, a second elastic element 112 sleeved on the outside of the movable rod 11 and connected at both ends to the support plate 3032 and one of the limiting plates 111 respectively, a traction rope 113 fixedly connected to the movable rod 11, and a locking component fixedly connected to the support plate 3032. The traction rope 113 has a locking plate 114 at the end away from the moving rod 11, an elastic telescopic rod 115 is provided on the outer wall of the locking plate 114 and the fixed end of the elastic telescopic plate 903, and a number of elastic telescopic inserts 116 are provided on the locking plate 114. The outer wall of the telescopic end of the elastic telescopic plate 903 is provided with a number of insertion holes 12 that cooperate with the elastic telescopic inserts 116. The limiting plate 111 near the force plate 3034 moves against the force plate 3034. It should be noted that the fixed end of the elastic telescopic plate 903 is provided with a concave hole corresponding to the elastic telescopic insert 116.

[0053] Furthermore, the end of the traction rope 113 away from the moving rod 11 passes sequentially through the fixed end of the fixed rod 902, the swing rod 901, and the elastic telescopic plate 903, and is finally fixedly connected to the locking plate 114. The support plate 3032, the fixed rod 902, the swing rod 901, and the elastic telescopic plate 903 are all provided with guide frames 13 that cooperate with the traction rope 113. The traction rope 113 is made of a wear-resistant and corrosion-resistant composite metal rope.

[0054] Specifically, when the hydraulic cylinder 302 extends to perform the clamping action, the clamping seat 303 moves forward as a whole. After the force plate 3034 contacts the end face of the workpiece, it stops moving forward, but the cylinder thrust continues to act, causing the slide rod 3033 to slide relative to the support plate 3032. The first elastic element 3036 is compressed, and the force plate 3034 moves closer to the support plate 3032. When the force plate 3034 moves to abut against the limiting plate 111 that is close to it and continues to move, it will push the moving rod 11 to overcome the elastic force of the second elastic element 112 and slide along the support plate 3032. The sliding pull of the traction rope 113 causes the traction rope 113 to change direction through each guide frame 13, ultimately transmitting the tension to the locking plate 114. Under the action of the tension, the locking plate 114 overcomes the resistance of the elastic telescopic rod 115 and moves towards the fixed end of the elastic telescopic plate 903. When the locking plate 114 approaches, the elastic telescopic insertion rod 116 on it passes through the fixed end of the elastic telescopic plate 903 and attempts to insert into the insertion hole 12 on the outer wall of the telescopic end of the elastic telescopic plate 903. Since there are multiple rows of insertion holes 12, even if the elastic telescopic plate 903 is at a certain telescopic length due to contact with the workpiece, it can still be inserted into the workpiece. At least one insertion hole 12 will align with the elastic telescopic rod 116. The aligned elastic telescopic rod 116 is inserted into the insertion hole 12, while the misaligned elastic telescopic rod 116 is compressed. Once inserted, the locking plate 114 is fixed, preventing any movement of the telescopic end of the elastic telescopic plate 903 relative to its fixed end, thus locking its length. Regardless of the magnitude of vibration or radial force generated during processing, the length of the elastic telescopic plate 903 remains fixed, thereby eliminating the possibility of slight expansion or creep that may occur due to its own elasticity under continuous stress, ensuring... The radial auxiliary clamping force remains constant throughout the entire processing cycle, enhancing the overall rigidity of the clamping system and providing a solid foundation for high-precision machining. When clamping ends, the hydraulic cylinder 302 retracts, the force plate 3034 moves away from the support plate 3032, and no longer applies pressure to the limit plate 111. Under the restoring force of the second elastic element 112, the moving rod 11 resets, the traction rope 113 loosens, and then the elastic telescopic rod 115 pushes the locking plate 114 back to its original position, causing the elastic telescopic insertion rod 116 to exit from the insertion hole 12, thus releasing the lock on the elastic telescopic plate 903.

[0055] The entire locking and unlocking process is driven entirely by the clamping action itself, without relying on sensors, solenoid valves or complex circuit control, thus avoiding potential faults, delays or interference problems in the electronic control system. It is suitable for long-term stable operation in harsh industrial environments with coolant, metal dust and other contaminants.

[0056] like Figure 1 and Figure 10 As shown, in a preferred embodiment, based on the above method, the processing unit 5 further includes a rotating shaft 501 rotatably disposed at the end of the robotic arm 4, a rotating plate 502 fixedly connected to the rotating shaft 501, a laser head 503 disposed at one end of the rotating plate 502, and a polishing brush 504 disposed at the other end of the rotating plate 502 and driven by a motor.

[0057] Specifically, when cutting a workpiece is required, the robotic arm 4 controls the rotation of its end shaft 501 to rotate, causing the laser head 503 on the rotating plate 502 to precisely rotate to a working position facing the workpiece surface. The laser head 503 is connected to the laser cutting system, which is existing technology and will not be elaborated further. The laser cutting system is started, and the laser head 503 emits a high-energy laser beam. At the same time, the robotic arm 4 performs multi-axis linkage according to the preset cutting path, driving the laser head 503 to move relative to the workpiece, thereby melting and cutting the required shape or contour on the workpiece. After laser cutting is completed, the robotic arm 4 controls the rotation of the rotating shaft 501 to rotate the grinding brush 504 at the other end of the rotating plate 502 to a working position facing the workpiece surface, replacing the original laser head 503. The motor driving the grinding brush 504 is started, causing the grinding brush 504 to... The robotic arm 4 rotates at high speed and moves again, controlling the high-speed rotating grinding brush 504 to move along the cutting edge or a specific path generated by laser cutting. The grinding brush 504 removes burrs, slag, and oxide layers from the cutting edge through physical contact and friction. After the grinding operation is completed, the grinding motor stops, and the robotic arm 4 can control the processing unit 5 to move to a safe position or standby posture, ready for the next processing operation. By integrating both laser cutting and grinding tools on a single processing unit 5 and switching between them through a simple rotational motion, the cutting and deburring processes can be completed continuously on the same equipment, in the same clamping, and in the same coordinate system. This eliminates the time and errors caused by the workpiece being transferred between the cutting machine and the grinding equipment and the secondary clamping and positioning in the traditional process, shortens the overall processing cycle, and improves production efficiency.

[0058] like Figure 1 and Figure 11As shown, in a preferred embodiment, based on the above method, the filter screen 7 further includes an elastic arc-shaped filter screen 701 and sliders 702 disposed on both sides of the arc-shaped filter screen 701. The top inner wall of the waste tank 6 is provided with a groove 14 for sliding the slider 702. A third elastic element 141 is disposed between the inner wall of the groove 14 and the slider 702.

[0059] Among them, the arc-shaped filter 701 is higher in the middle and lower on both sides;

[0060] Specifically, during routine processing, waste chips and sparks generated from cutting and grinding fall onto the filter screen 7. Smaller particles in the waste, such as dust and fine debris, fall directly into the waste trough 6 below through the mesh of the arc-shaped filter screen 701. Larger or longer waste materials, such as molten slag and metal strips, are intercepted on the surface of the arc-shaped filter screen 701. Under the influence of gravity, the intercepted large pieces of waste may roll or slide to the lower sides, which helps to concentrate naturally and prevents them from accumulating in the middle, thus avoiding affecting the falling of small particles. When a heavier object with greater kinetic energy, such as a small workpiece that has accidentally fallen off, a large piece of waste, or a valve body, falls onto the filter screen 7, the impact force acts on the arc-shaped filter screen 701. The surface of the filter screen 701 is first deformed by its own elasticity, and it is concave downward, converting part of the impact kinetic energy into the elastic potential energy of the filter screen material. Secondly, the deformation of the filter screen is transmitted to the slide groove 14 through the sliders 702 on both sides. Under the action of the impact force, the sliders 702 compress the third elastic element 141 between itself and the inner wall of the slide groove 14, further converting the remaining impact kinetic energy into the potential energy of the elastic element, absorbing and dissipating the impact energy of the falling object, and converting the impact force into the elastic deformation energy of the entire system. This significantly reduces the peak stress and fatigue damage borne by the filter screen structure itself, thereby improving its durability and reliability and reducing replacement and maintenance costs.

[0061] This invention also discloses a method of using a magnetic pump valve housing cutting device, comprising the following steps:

[0062] S1: The operator places the magnetic pump valve housing to be cut horizontally between the two clamping parts 3, so that the axis of the housing is roughly aligned with the center of the clamping seats 303 on both sides.

[0063] S2: Start the hydraulic cylinders 302 on both sides. The piston rod pushes the clamping seat 303 to move towards the middle shell. The force plate 3034 on each clamping seat 303 first contacts the end face of the shell. Under the continuous action of hydraulic force, the force plate 3034 is subjected to a reaction force, which drives the slide rod 3033 to stretch the first elastic element 3036 and slide towards the support plate 3032 to achieve initial buffering.

[0064] The movable plate 3035 at the other end of the slide bar 3033 moves accordingly. Through the force rod 9, swing rod 901 and elastic telescopic plate 903 of the auxiliary clamping assembly, multiple V-shaped plates 10 are driven to approach and finally fit the irregular side wall of the shell from all sides. Due to the expansion and contraction compensation of the elastic telescopic plate 903, each V-shaped plate 10 can adapt to the concave and convex contours of the side of the shell and achieve adaptive wrapping.

[0065] When the force plate 3034 is about to be tightly attached to the limiting plate 111, the moving rod 11 is pushed, and the locking plate 114 is pulled by the traction rope 113, so that the elastic telescopic rod 116 is inserted into the insertion hole 12 of the elastic telescopic plate 903, locking the current telescopic length of the elastic telescopic plate 903, thereby fixing the clamping position of all V-shaped plates 10 and forming a rigid support. When the force plate 3034 is finally tightly attached to the limiting plate 111, the clamping force reaches the set value.

[0066] S3: The drive motor 8 on one side is started, which drives the clamping part 3 and the clamped shell to rotate as a whole. The clamping part 3 on the other side rotates under the drive of the workpiece, so that the part of the shell that needs to be cut rotates to the processing position.

[0067] The robotic arm 4 moves to drive the processing unit 5 to position itself. First, the rotating plate 502 aligns the laser head 503 with the cutting path to perform the cutting operation.

[0068] After the cutting is completed, the robotic arm 4 drives the processing unit 5 to retract, and the rotating plate 502 rotates at the end of the robotic arm 4, so that the grinding brush 504 is aligned with the newly generated cutting edge. The robotic arm 4 controls the grinding brush 504 to move along the cut to grind and clean the burrs and slag generated by laser cutting.

[0069] S4: The debris and sparks generated from cutting and grinding fall downwards and pass through the filter screen 7. Large particles of waste are intercepted by the filter screen 7, while fine dust falls into the waste trough 6 below for collection. If the workpiece accidentally falls off, the arc-shaped filter screen 701 and its elastic connection structure can buffer the impact and prevent damage to the workpiece and equipment.

[0070] S5: After all processing is completed, the piston rod of hydraulic cylinder 302 retracts, clamping seat 303 is released, and the operator removes the processed outer shell.

In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.
