Description
Technical Field
[0001] This invention relates to the field of wire clamp manufacturing technology, and in particular to a suspension wire clamp manufacturing equipment and method with uniform gripping force. Background Technology
[0002] Suspension clamps are essential hardware in ultra-high-voltage transmission lines, and are typically made of aluminum alloy. They are used to secure conductors to insulator strings on straight-line towers, suspend lightning protection wires on straight-line towers, and also to support transposed conductors on transposed towers and secure jumpers on tension angle towers.
[0003] Suspension clamps are critical components of power transmission lines. The uniformity of their gripping force directly affects the safety and lifespan of the conductors, and the accuracy of the hole positions in the "hull" section of the clamp body is an important prerequisite for achieving uniform gripping force. Currently, drilling of aluminum alloy hulls mainly relies on two modes: The first is traditional fixed-station machining, where the hull is transported to a specific station on a conveyor line, clamped by a fixture, and then drilled by a drilling machine. While this mode can guarantee a certain level of accuracy, the "convey-stop-position-machining-release" process cycle suffers from significant interruptions in cycle time, resulting in low production efficiency and difficulty in meeting the demands of large-scale production. The second approach attempts to perform "online drilling" on moving workpieces during continuous conveying. However, this faces a fundamental technical challenge: if the drilling unit is required to move completely synchronously with the workpiece, its complex precision transmission mechanism must perform high-speed, high-precision synchronous movement while bearing the machining load, which is extremely technically difficult and costly, and dynamic stability is difficult to guarantee. Summary of the Invention
[0004] The purpose of this invention is to solve the problems in existing suspension clamp drilling processes, such as the need for workpiece shutdown during fixed-station processing, resulting in interrupted process cycles, low production efficiency, and difficulty in meeting the needs of large-scale production; the inability to achieve precise adaptive centering positioning during moving workpiece processing, leading to poor hole position accuracy and directly affecting the uniformity of clamp gripping force; and the need for multiple independent drive sources for multi-face drilling, resulting in complex systems and poor synchronization accuracy. This invention proposes a suspension clamp production equipment and method with uniform gripping force. It optimizes the overall modularization of workpiece conveying, workpiece positioning, multi-face drilling, and processing cycles, achieving independent cyclic linkage of multiple drilling sections based on a closed-loop track. The invention organically combines a drilling section cyclic conveying mechanism composed of multiple independent moving components, a moving workpiece adaptive centering positioning mechanism composed of symmetrical roller pressure rods, and a rigid following processing mechanism. This is achieved through a multi-section cyclic operation of the drilling sections and mechanical linkage of a single drive source, enabling continuous automated operation throughout the entire process, including multiple drilling sections cyclically capturing workpieces, adaptive centering positioning during movement, synchronous drilling processing, and rapid return without load.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A suspension clamp production device with uniform gripping force, comprising a U-shaped frame, and further comprising: The conveying section is provided in two sets, which are respectively located on both sides of the U-shaped frame, for conveying the hull of the suspension clamp; The drilling section is movable on the upper side of the U-shaped frame. The drilling section includes a positioning component for positioning the hull and a first drilling component and a second drilling component for drilling holes in the bottom and sides of the hull, respectively. The reciprocating conveying mechanism is located on one side of the U-shaped frame and is used to convey the punched part and move it back and forth along the length of the U-shaped frame.
[0006] Preferably, each of the conveying units includes a drive roller, a driven roller, a plurality of auxiliary support rollers rotatably disposed on the same side of the U-shaped frame, and a conveyor belt connecting the drive roller and the driven roller, wherein the U-shaped frame is provided with a conveyor motor for driving the drive roller to rotate.
[0007] Preferably, the reciprocating conveying mechanism includes a track frame mounted on one side of the U-shaped frame via a support rod, a track groove mounted at the bottom of the track frame, and a movable component slidably connected in the track groove. The movable component is fixedly connected to the perforated part, and multiple sets of both the movable component and the perforated part are provided. The track frame includes two semi-circular frames and a cross frame disposed between the two semi-circular frames. The cross frame is placed on the upper side of the U-shaped frame and is arranged parallel to the U-shaped frame.
[0008] Preferably, the moving component includes a moving plate movably disposed in the track groove, a moving motor fixedly disposed on the moving plate, a drive shaft connected to the output end of the moving motor and rotatably disposed on the moving plate, a drive gear fixedly connected to the drive shaft, and a rack and pinion disposed in the track groove and meshing with the drive gear.
[0009] Preferably, the movable plate is connected to a plurality of ball bearings by a connecting rod, and the inner wall of the track groove is provided with a sliding groove for the ball bearings to slide.
[0010] Preferably, the positioning assembly includes a mounting plate fixedly connected to a support rod and a connecting rod, a first electric push rod fixedly connected to the mounting plate, a movable frame disposed at the movable end of the first electric push rod, a pressure rod disposed at the bottom of the movable frame, and a roller disposed at the bottom of the pressure rod. The roller moves against the inner wall of the curved surface of the hull. An infrared sensor for detecting the hull is disposed on the mounting plate.
[0011] Preferably, the first drilling assembly includes a second electric push rod fixed on the mounting plate, a lifting plate connected to the movable end of the second electric push rod, and a plurality of first electric drills disposed on the lifting plate.
[0012] Preferably, the second drilling assembly includes a screw mounted on a movable frame, a nut seat threadedly connected to the screw, a movable plate mounted on the outside of the nut seat, and a second electric drill fixedly mounted on the movable plate.
[0013] Preferably, the lifting plate is provided with a rack plate via a connecting plate, and the screw is provided with a driven gear that meshes with the rack plate. The screw is rotatably mounted on the movable frame.
[0014] This invention also discloses a method for producing a suspension clamp with uniform gripping force, which involves using the aforementioned suspension clamp production equipment to produce the clamp, and includes the following steps: S1: Feeding and Conveying The suspended clamp hull, which has been processed in the previous process, is placed on the U-shaped frame. The side walls on both sides of the hull are supported and straightened by auxiliary support rollers and conveyor belts. The conveyor motor is started to drive the drive roller to rotate, and the hull is continuously conveyed forward along the length of the U-shaped frame through the conveyor belt. S2: The punching section moves in a circular motion. Simultaneously control the operation of the moving motors on multiple moving components. The moving motors control the rotation of the drive shaft and drive gear. The gear meshes with the rack frame fixed in the track groove. The driving moving plate slides in the slide groove through the ball bearings. The moving plate drives the entire drilling part to move along the closed ring track composed of two semi-circular frames and two cross frames through the connecting rod. Multiple drilling parts circulate on this ring track. S3: Capture, Positioning, and Synchronization When one of the drilling sections moves to the crossbeam section on the upper side of the U-shaped frame, the infrared sensor on the mounting plate of the drilling section detects that a ship is passing below, and controls the first electric push rod to start, pushing the moving frame and pressure rod down. The roller at the bottom of the pressure rod contacts the inner arc surface of the ship. Relying on the adaptive adjustment of the pressure rods on both sides, the ship is finally symmetrically pressed and positioned from both sides of the inner wall. At this time, the drilling section drives the ship to move synchronously, forming a follow-up processing state. S4: Synchronous drilling Execute the drilling procedure while maintaining synchronized motion; Bottom drilling: The second electric push rod is activated, pushing the lifting plate and the first electric drill tool to move down and drill holes in the bottom of the hull; Side drilling linkage: As the lifting plate moves down, the rack plate fixed to it drives the driven gear and screw to rotate. The rotation of the screw is converted into the horizontal movement of the nut seat, thereby pushing the movable plate and the second electric drill to feed towards the side wall of the hull to complete the side hole machining. The bottom and side hole machining are carried out simultaneously. S5: Reset and Loop After drilling is completed, the first and second electric push rods of the drilling section retract in sequence, the drilling section detaches from the hull, and the moving component enters the semi-circular frame track along the end of the crossbeam. It returns to the starting end unloaded, ready to enter the next work cycle. At the same time, the subsequent drilling section has moved to the position of the crossbeam section on the upper side of the U-shaped frame, ready to capture and process the next hull, realizing continuous flow operation.
[0015] Compared with the prior art, the present invention provides a production equipment and method for suspension wire clamps with uniform gripping force, which has the following beneficial effects: 1. In this invention, by setting up multiple drilling sections driven by independent moving motors, the moving speed of the moving components is always controlled to be greater than the conveying speed of the conveying section to the hull. This allows the completed drilling section to be quickly reset under no-load along the track frame and catch up with the subsequent hulls to be processed on the conveying line by virtue of its speed advantage. This achieves continuous capture of workpieces by the processing unit, eliminates waiting time between processes, and enables seamless connection between drilling and material conveying, thus realizing uninterrupted production on the assembly line.
[0016] 2. In this invention, the positioning component uses symmetrically arranged pressure rods with bottom rollers, driven by a first electric push rod. When the drilling part catches up with the workpiece and presses down, even if the two pressure rods do not contact the symmetrical arc surface at the same time, the roller on the side that contacts first will apply a lateral thrust to the workpiece under pressure, forcing the workpiece to slip slightly on the conveyor belt until the other pressure rod also contacts and presses it. This achieves adaptive centering and pressing of the arc-shaped workpiece in continuous motion without the need for precise centering, laying the benchmark for subsequent high-precision drilling.
[0017] 3. In this invention, after the pressure rod presses down and locks the workpiece, the workpiece, the drilling part, and the moving component become a moving whole in the horizontal direction. Since the driving force of the moving component is rigid and the speed is constant, and the conveyor belt has a very weak constraint force on the workpiece that has been pressed and positioned, the workpiece is forced to move at the same constant speed as the drilling part. The two maintain a relatively stationary state without slippage during the drilling process, thereby ensuring the hole position accuracy, perpendicularity, and hole diameter quality, thus providing a guarantee for achieving uniform force distribution on the suspension clamp bolt and achieving uniform gripping performance.
[0018] 4. In this invention, multi-angle drilling of the hull is completed by using a single power source. The second electric push rod drives the lifting plate to perform vertical feed for bottom drilling, while the rack plate fixed on the lifting plate moves accordingly. The rack plate drives the driven gear to rotate, thereby driving the screw to rotate. Finally, the rotational motion is converted into horizontal feed for lateral drilling by the second electric drill through the nut seat. This realizes automatic and precise coordination of the two degrees of freedom of bottom drilling and side drilling in terms of timing and feed. This pure mechanical linkage method does not require additional control components and power sources, has high synchronization accuracy, and solves the problem of traditional multi-face drilling requiring multiple clamping or multiple equipment, which is cumbersome and has accumulated errors. The failure rate and maintenance cost are significantly reduced. Attached Figure Description

[0021] 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.
[0022] 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.
[0023] like Figures 1 to 6 As shown, this embodiment proposes a suspension clamp production equipment with uniform gripping force, including a U-shaped frame 1, and further including: a conveying section 2, a punching section 4, and a reciprocating conveying mechanism; the conveying section 2 is provided in two sets and is respectively arranged on both sides of the U-shaped frame 1 for conveying the hull 3 of the suspension clamp; the punching section 4 is movable on the upper side of the U-shaped frame 1, and the punching section 4 includes a positioning component for positioning the hull 3 and a first punching component and a second punching component for punching holes on the bottom and sides of the hull 3 respectively; the reciprocating conveying mechanism is arranged on one side of the U-shaped frame 1 for conveying the punching section 4 and moving it back and forth along the length direction of the U-shaped frame 1; Specifically, the suspended clamp hull 3 to be processed is placed on the U-shaped frame 1. Two symmetrically arranged conveyor units 2 are activated, positioning and conveying the hull 3 from both sides, ensuring its continuous and stable forward movement along a predetermined path on the U-shaped frame 1. This provides a dynamic workpiece flow for subsequent processing. The reciprocating conveyor mechanism located on one side of the U-shaped frame 1 is controlled. Depending on the production line's cycle time requirements, 3-8 independent drilling units 4 and moving components can be configured to ensure that when the previous drilling unit 4 completes its processing and returns, the next drilling unit 4 has already completed workpiece capture and positioning, achieving uninterrupted continuous production. The drilling unit 4 moves from its initial position along the length of the U-shaped frame 1 until it reaches and hovers directly above the conveying hull 3. When the drilling unit 4 reaches the processing position, its package... The positioning component is activated to perform positioning operations such as gripping, centering, or clamping on the moving hull 3 below, so that the workpiece remains stable relative to the drilling part 4 at the moment of processing. After positioning is completed, the first and second drilling components are activated separately or simultaneously to perform drilling operations on the bottom and sides of the positioned hull 3. After the drilling of the current hull 3 is completed, the positioning component releases the workpiece, and the reciprocating conveyor drives the drilling part 4 to move along the preset trajectory and return to its initial position, ready to repeat the above steps for the next hull 3 that is subsequently conveyed, so as to realize cyclic processing. This changes the inherent process of material stopping and processing in the traditional fixed station processing mode, and provides a structural framework for the final realization of non-stop assembly line production, which helps to reduce the transfer and waiting time between processes and improve the production cycle.
[0024] like Figure 1 , Figure 2 and Figure 3As shown, in a preferred embodiment, based on the above method, each conveying unit 2 further includes a driving roller 201, a driven roller 202, several auxiliary support rollers 203 rotatably arranged on the same side of the U-shaped frame 1, and a conveyor belt 204 connecting the driving roller 201 and the driven roller 202. The surface of the conveyor belt 204 may be provided with anti-slip and wear-resistant texture. A conveyor motor 205 for driving the driving roller 201 to rotate is provided on the U-shaped frame 1. Specifically, by providing two sets of conveying units 2 with identical structures on both sides of the U-shaped frame 1, a conveying method for positioning and driving from both sides is provided. The conveyor motors 205 on both sides can be simultaneously... Step control ensures that the linear speed of the conveyor belts 204 on both sides is consistent, thereby avoiding problems such as workpiece deviation, twisting or jamming that may be caused by unilateral drive; the conveyor motor 205 starts, and its output shaft drives the active roller 201 on the same side to rotate. The active roller 201 drives the conveyor belt 204 around it to move through friction. The conveyor belt 204 forms a closed loop cyclic motion under the guidance of the driven roller 202 and is supported by the auxiliary support roller 203. The hull 3, placed between the belts of the two sets of conveyor sections 2, has its two sides in contact with the conveyor belts 204 on both sides. Under the action of belt friction, it is clamped and continuously conveyed forward along the length direction of the U-shaped frame 1.
[0025] like Figure 1 , Figure 2 , Figure 6 , Figure 10 and Figure 11 As shown, in a preferred embodiment, based on the above method, the reciprocating conveying mechanism further includes a track frame 5 set on one side of the U-shaped frame 1 by a support rod, a track groove 6 set at the bottom of the track frame 5, and a moving component slidably connected in the track groove 6. The moving component is fixedly connected to the perforated part 4, and multiple sets of both the moving component and the perforated part 4 are provided. A closed annular drag chain can be set inside the track frame 5. All power supply and control cables of the perforated parts 4 are integrated in the drag chain and move synchronously with the moving component to avoid cable pulling and tangling, and ensure the reliability of long-term continuous operation of the equipment. The track frame 5 includes two semi-circular frames 501 and a cross frame 502 disposed between the two semi-circular frames 501. The cross frame 502 is placed on the upper side of the U-shaped frame 1 and is arranged parallel to the U-shaped frame 1. Furthermore, the moving components include a moving plate 7 movably disposed within the track groove 6, a moving motor 701 fixedly disposed on the moving plate 7, a drive shaft 702 connected to the output end of the moving motor 701 and rotatably disposed on the moving plate 7, a drive gear 703 fixedly connected to the drive shaft 702, and a rack frame 704 disposed within the track groove 6 and meshing with the drive gear 703, ensuring that the moving speed of the drilling section 4 is controllable and stable throughout the entire process. It should be noted that each set of moving components can be equipped with a laser rangefinder sensor. When the distance between adjacent drilling sections 4 is less than a safety threshold, the rear drilling section 4 automatically decelerates to avoid rear-end collisions. Furthermore, a number of ball bearings 7051 are connected to the movable plate 7 via a connecting rod 705, and a groove 601 for sliding the ball bearings 7051 is provided on the inner wall of the track groove 6. Specifically, the moving motor 701 starts, and the drive shaft 702 drives the drive gear 703 to rotate. The rotating drive gear 703 meshes with the fixed rack frame 704, generating driving force. This force pushes the entire moving plate 7 and its connected drilling part 4 to move along the direction of the rack frame 704, that is, along the trajectory of the track groove 6. The ball bearings 7051 roll in the slide groove 601, bearing the load and ensuring smooth and stable movement. The inner wall of the track groove 6 can also be provided with support plates for supporting the moving plate 7 as needed. Under the guidance of the annular track frame 5, the moving component drives the drilling part 4 to form a continuous annular motion path, overlapping the two stages of processing and resetting in space and time, so that the drilling processing is almost continuous, eliminating the inherent idle waiting time of the single drilling part 4 equipment, and improving the overall output efficiency of the equipment. When the moving component runs in the track groove 6 of the crossbeam 502 above the U-shaped frame 1, the drilling part 4 below it can move down and perform the processing work of the hull 3.
[0026] like Figure 5 , Figure 6 , Figure 7 and Figure 9 As shown, in a preferred embodiment, based on the above method, the positioning component further includes a mounting plate 8 fixedly connected to the support rod and the connecting rod 705, a first electric push rod 801 fixedly connected to the mounting plate 8, a movable frame 802 disposed at the movable end of the first electric push rod 801, a pressure rod 803 disposed at the bottom of the movable frame 802, and a roller 804 disposed at the bottom of the pressure rod 803. The roller 804 moves against the inner wall of the arc surface of the hull 3. The outer surface of the roller 804 is covered with a polyurethane buffer layer to protect the inner arc surface of the workpiece. An infrared sensor for detecting the hull 3 is provided on the mounting plate 8. Specifically, when the drilling section 4 moves to the processing area, i.e. above the U-shaped frame 1, driven by the reciprocating conveyor mechanism, the infrared sensor on the mounting plate 8 detects downwards. Once a hull 3 enters its detection range, a signal is sent (after the infrared sensor detects the workpiece, it first controls the moving motor 701 to adjust its speed to synchronize with the conveying speed, and then starts the first electric push rod 801 to press down and position. Only when the pressure rod is pressed down to the set stroke and the workpiece is pressed into place can the second electric push rod 9 and the electric drill be started to perform the drilling action, avoiding the risk of processing before positioning). After receiving the signal, the first electric push rod 801 starts, its movable end extends, and pushes the moving frame 802 and the pressure rod 803 fixed on it to move downwards. The roller 804 at the bottom of the pressure rod 803 also descends until it is in contact with the hull below. The inner arc surface of the hull 3 contacts and applies pressure. When the pressure rod 803 is pressed down, the roller 804 and the inner arc surface of the hull 3 are in a rolling friction relationship of line contact. The pressure rod 803 will automatically apply a thrust to the inner wall of the arc surface of the hull 3. The auxiliary support roller 203 cooperates to restrict and position the two side walls of the hull 3 to prevent the hull 3 from tilting and to make the hull 3 displace relative to the pressure rod 803. The roller 804 can reduce the wear caused by relative movement. Finally, the pressure rods 803 on both sides of the mounting plate 8 can press down symmetrically on the corresponding positions on both sides of the inner wall of the hull 3 at the same time. At this time, the pressure on the hull 3 is stopped to avoid deformation and surface damage of the hull 3 workpiece caused by excessive pressure. At this time, the roller 804 at the bottom of the pressure rod 803 will no longer move arbitrarily relative to the hull 3. While ensuring the positioning effect of the hull 3, the positioning efficiency of the hull 3 is accelerated.
[0027] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the first drilling assembly further includes a second electric push rod 9 fixed on the mounting plate 8, a lifting plate 901 connected to the movable end of the second electric push rod 9, and a plurality of first electric drills 902 disposed on the lifting plate 901. Furthermore, the second drilling assembly includes a screw 10 mounted on the movable frame 802, a nut seat 1001 threadedly connected to the screw 10, a movable plate 1002 mounted on the outside of the nut seat 1001, and a second electric drill 1003 fixedly mounted on the movable plate 1002. A telescopic rod can be provided between the movable plate 1002 and the movable frame 802 for guiding the movement of the movable plate 1002. Furthermore, a rack plate 11 is provided on the lifting plate 901 via a connecting plate, and a driven gear 111 that meshes with the rack plate 11 is provided on the screw 10. The screw 10 is rotatably mounted on the moving frame 802.
[0028] Specifically, after the positioning assembly positions the hull 3, the second electric drill 1003 of the second drilling assembly connected to the moving frame 802 is at the drilling height position on the side wall of the hull 3. When drilling is required, the second electric push rod 9 is activated, and its movable end extends downward, pushing the lifting plate 901 and the first electric drill 902 fixed on it to move downward as a whole, performing vertical drilling operations on the bottom of the hull 3. At the same time as the lifting plate 901 moves downward, the rack plate 11 fixed on it moves downward synchronously. The downward movement of the rack plate 11 drives the driven gear 111 meshing with it to rotate. The rotation of the driven gear 111 drives the screw 10 fixed on it to rotate together. The rotational motion of the screw 10 is converted into linear motion of the nut seat 1001 along the axis of the screw 10 through the threaded pair. The nut seat 1001 drives the movable plate 100 2 and the second electric drill 1003 feed horizontally towards the side wall of the hull 3 to perform horizontal drilling on the side of the hull 3. After drilling is completed, the second electric push rod 9 retracts, driving the lifting plate 901 and the first electric drill 902 to rise. At this time, the rack plate 11 rises, driving the driven gear 111 to rotate in the opposite direction, which in turn drives the screw 10 to reverse, so that the nut seat 1001, the movable plate 1002 and the second electric drill 1003 retract horizontally and detach from the workpiece. By optimizing the transmission ratio of the rack plate 11 and the driven gear 111 and the lead of the screw 10, when the lifting plate 901 moves down to the end of the stroke of the first electric drill 801 to complete the bottom hole drilling, the nut seat 1001 just drives the second electric drill 1003 to complete the side hole feed drilling, so that the bottom hole and side hole processing start and end synchronously, ensuring precise matching of processing sequence. In traditional processes, bottom holes and sidewall holes often require two separate clamping operations or two separate machines for step-by-step processing, which is time-consuming and prone to cumulative errors. This application integrates the first drilling assembly and the second drilling assembly into the same movable processing unit, enabling drilling in two directions to be completed in one positioning, significantly shortening the processing cycle of a single workpiece. Both the first electric drill 902 and the second electric drill 1003 can adopt quick-change mounting bases, which can quickly change the drill according to the processing hole diameter, and the installation position of the drill can be adjusted to adapt to the processing requirements of different hole positions. Meanwhile, the lateral feed motion is not provided by an additional motor or cylinder, but borrows power from the main push rod through mechanical linkage. This simplifies the electrical and control system of the drilling section 4, reduces the configuration, wiring and control loop of one driver, lowers hardware costs and software programming complexity, provides good long-term stability, is relatively simple to maintain, and has higher environmental adaptability and operational reliability than systems that rely on multiple servo coordination.
[0029] In this device, the electric push rod, motor, electric drill, bearing, gear, rack, etc. are all industrial standard parts. Non-standard structural parts (track frame 5, U-shaped frame 1, moving frame 802) can be formed by conventional machining and sheet metal welding processes, without the need for special customization, making it suitable for mass production.
[0030] This invention also discloses a method for producing a suspension clamp with uniform gripping force, which involves manufacturing the clamp using the aforementioned equipment for producing suspension clamps with uniform gripping force, and includes the following steps: S1: Feeding and Conveying The suspended clamp hull 3, which has been processed in the previous process, is placed on the U-shaped frame 1. The side walls on both sides of the hull 3 are supported and straightened by the auxiliary support rollers 203 and the conveyor belt 204. The conveyor motor 205 is started to drive the active roller 201 to rotate. The hull 3 is continuously conveyed forward along the length of the U-shaped frame 1 through the conveyor belt 204. S2: The perforated section moves in 4 cycles. Simultaneously, the operation of the moving motors 701 on multiple sets of moving components is controlled. The moving motors 701 control the rotation of the drive shaft 702 and the drive gear 703. The gear meshes with the rack frame 704 fixed in the track groove 6. The driving moving plate 7 slides in the slide groove 601 through the ball bearings 7051. The moving plate 7 drives the entire drilling part 4 to move along the closed ring track composed of two semi-circular frames 501 and two cross frames 502 through the connecting rod 705. The multiple sets of drilling parts 4 circulate on the ring track. S3: Capture, Positioning, and Synchronization When one of the drilling sections 4 moves to the crossbeam 502 section on the upper side of the U-shaped frame 1, the infrared sensor on the mounting plate 8 of the drilling section 4 detects that the hull 3 is passing below, and controls the first electric push rod 801 to start, pushing the moving frame 802 and the pressure rod 803 down. The roller 804 at the bottom of the pressure rod 803 contacts the inner arc surface of the hull 3. Relying on the adaptive adjustment of the pressure rods 803 on both sides, the hull 3 is finally symmetrically pressed and positioned from both sides of the inner wall. At this time, the drilling section 4 drives the hull 3 to move synchronously, forming a follow-up processing state. S4: Synchronous drilling Execute the drilling procedure while maintaining synchronized motion; Bottom drilling: The second electric push rod 9 is activated, pushing the lifting plate 901 and the first electric drill 902 to move down and drill holes in the bottom of the hull 3; Side drilling linkage: While the lifting plate 901 moves down, the rack plate 11 fixed to it drives the driven gear 111 and the screw 10 to rotate. The rotation of the screw 10 is converted into the horizontal movement of the nut seat 1001, thereby pushing the movable plate 1002 and the second electric drill 1003 to feed towards the side wall of the hull 3 to complete the side hole processing. The bottom and side hole processing are carried out simultaneously. S5: Reset and Loop After drilling is completed, the first electric push rod 801 and the second electric push rod 9 of the drilling section 4 retract in sequence. The drilling section 4 is separated from the hull 3. The moving component enters the semi-circular frame 501 track along the end of the cross frame 502 and returns to the starting end unloaded, ready to enter the next work cycle. At the same time, the subsequent drilling section 4 has moved to the position of the cross frame 502 section on the upper side of the U-shaped frame 1, ready to capture and process the next hull 3, realizing continuous flow operation.
