Description

Technical Field

[0001] The invention relates to the field of special tools for aerostats, and in particular to a power storage and firing type hole punching device for an aerostat bladder and a working method thereof. Background Art

[0002] Compared with other aircraft such as drones, aerostats have the advantages of better cost-effectiveness, good carrying capacity and long hovering time, and are therefore widely used in the fields of exploration, geological disaster monitoring, navigation communication, and early warning positioning. A metal flange is installed on the airship capsule, and the capsule needs to be punched before flight to facilitate the installation and connection of the flange. Existing punching devices mostly use pliers-type punchers, which punch holes by grasping and pressing the handle. When the handle is pressed, the spring is squeezed and stored. After the punching is completed, the spring rebound force is used to reset the handle. The punching speed during the punching depends on the user's grip and pressing speed. Since a large number of holes need to be punched at the metal flange position of the airship capsule, after a long period of drilling, the user's fatigue will cause the grip force and pressing speed to be difficult to meet the requirements, and burrs are prone to appear on the edge of the hole. The punching efficiency is not high, and it is difficult to apply to the scene of a large number of holes being punched on the airship capsule layout site.

[0003] A Chinese patent (publication number CN205097277U, publication date 2016-03-23) discloses an adjustable puncher, including a frame, a lower die fixedly arranged on the frame, an upper die capable of moving up and down along the height direction of the frame, and a driving mechanism for driving the upper die to move up and down. The distance between the upper die and the lower die can be achieved by rotating an adjustment ring, which is suitable for products to be punched of various thicknesses. The downward movement of the upper die enables the spring to complete the storage of potential energy, and the upper die can automatically reset during use; however, the speed of impacting the product to be punched during punching still depends on the speed of the operator pressing down the pressure rod. It is difficult to control the quality of the punching when a large number of holes are punched, and burrs are likely to appear on the edge of the hole, affecting the installation accuracy of the subsequent flange; in addition, when punching, the cutter head contacts the product first, and before the cutter head completes cutting the product into a hole, the hole area cannot be fixed, which easily causes the product to shift, resulting in a deviation in the hole position, affecting the hole accuracy and then causing a matching deviation with the metal flange. Summary of the invention

[0004] The purpose of the present invention is to address the defects of the prior art and to provide a force-storage trigger-type punching device and a working method for an aerostat bladder. The device utilizes the energy-storage spring connected to the punching knife to store energy when the knife handle rotates relative to the clamp body. When the hook is driven to rotate to the trigger member, the punching knife is unhooked. The energy-storage spring is released to drive the punching knife to achieve fast and stable impact punching, thereby reducing burrs on the edge of the hole. The pressure plate is connected to the knife handle by an elastic pull rod so that the pressure plate moves with the knife handle. When the punching knife stores energy, the bladder to be punched is gradually clamped by the clamping part. When the hook triggers the punching knife to pass through the clamping part to punch a hole, the pressure plate and the clamp body maintain a clamping state on the bladder, thereby reducing the displacement of the bladder caused by punching and improving the hole position accuracy, thereby jointly achieving an improvement in the punching accuracy and meeting the demand for a large number of holes when the flange is installed on the bladder.

[0005] The first object of the present invention is to provide a power storage percussion punching device for an aerostat bladder, which adopts the following scheme:

[0006] The caliper body is slidably fitted with a punch through the first hole, a trigger is installed outside one axial end of the first hole, the head end of the punch is located between the first hole and the trigger, and an energy storage spring is connected between the punch and the caliper body;

[0007] The knife handle is rotatably mounted on the clamp body, and a hook is rotatably mounted on one end of the knife handle. One end of the hook can hook the punching knife and drive the punching knife to slide along the first channel, and the other end of the hook can contact the trigger member under the rotation drive of the knife handle to release the hook from hooking the punching knife.

[0008] The pressure plate is slidably matched with the pliers body, and a clamping part for the end of the punching knife to be inserted is formed between the pressure plate and the pliers body. A knife pad for accommodating the end of the punching knife is provided on the pressure plate. The pressure plate is connected to the knife handle through an elastic pull rod so that the size of the clamping part can be adjusted under the drive of the knife handle.

[0009] Furthermore, a return spring is abutted between one end of the hook hook punch and the handle, and the trigger member can be adjustably installed on the pliers body to adjust the position where the hook contacts the hook.

[0010] Furthermore, the clamp body is provided with a second hole parallel to the first hole, and the elastic pull rod is slidably matched with the second hole.

[0011] Furthermore, one end of the elastic pull rod is fixed to the pressure plate, and the other end is provided with a guide column, and the tool handle is provided with a guide groove, and the guide column and the guide groove are slidably matched so that the tool handle applies traction force to the elastic pull rod along the axial direction of the elastic pull rod.

[0012] Furthermore, the elastic pull rod is provided with a pull rod spring which is telescopic in the axial direction, and the elastic pull rod is extended by overcoming the elastic force of the pull rod spring when driven by the caliper body.

[0013] Furthermore, a movable pin is installed on the punching knife, and the movable pin is slidably matched with a preset slideway on the caliper body. The sliding direction of the movable pin along the slideway is parallel to the axis of the first channel, and one end of the energy storage spring is connected to the punching knife through the movable pin.

[0014] Furthermore, a fixing pin is installed on the caliper body, and the other end of the energy storage spring is connected to the caliper body through the fixing pin.

[0015] Furthermore, the caliper body is provided with an installation cavity, the knife handle is rotatably installed in the installation cavity, the caliper body is provided with a first handle, the knife handle is provided with a second handle, the caliper body is provided with a sliding sleeve, and a first channel is formed inside the sliding sleeve.

[0016] The second object of the present invention is to provide a working method of the power storage percussion punching device for an aerostat bladder as described in the first object, comprising:

[0017] Arrange the capsule in the clamping portion, with the position to be punched corresponding to the knife pad;

[0018] The knife handle is driven to rotate, and the knife handle drives the hook to hook one end of the punch, driving the punch gradually close to the trigger member, pulling the energy storage spring to store force; at the same time, the knife handle drives the pressure plate to move through the elastic pull rod, so that the pressure plate cooperates with the clamp body to clamp the capsule in the clamping part;

[0019] When the knife handle continues to rotate until the hook contacts the triggering member, the hook contacts the hook of the punching knife, and the punching knife is driven to move under the action of the energy storage spring, and the end thereof penetrates into the clamping part to punch a hole in the capsule;

[0020] After the drilling is completed, the knife handle rotates and resets, the pressure plate releases the clamping of the capsule, the hook resumes the hooking of the punch knife head end, the capsule is taken out, and the next hole is drilled.

[0021] Furthermore, the trigger position of the hook is changed by adjusting the distance between the trigger member and the first hole, and the impact speed and impact force of the punch on the capsule are changed by adjusting the specification parameters of the energy storage spring.

[0022] Compared with the prior art, the present invention has the following advantages and positive effects:

[0023] In view of the problem that the hole accuracy is difficult to meet the demand when punching a large number of holes on the capsule, the energy storage spring connected to the punching knife is stored when the knife handle rotates relative to the clamp body. When the hook is driven to rotate to the trigger member, the hook of the punching knife is released. The energy storage spring is released to drive the punching knife to achieve fast and stable impact punching, reducing burrs on the hole edge; the pressure plate is connected to the knife handle through an elastic pull rod so that the pressure plate follows the movement of the knife handle. When the punching knife accumulates force, the capsule to be punched is gradually clamped through the clamping part, and when the hook triggers the punching knife to pass through the clamping part to punch, the pressure plate and the clamp body maintain the clamping state of the capsule, reducing the displacement of the capsule caused by punching, and the punching accuracy is improved by the stored force firing and pre-clamping clamping, meeting the demand for a large number of holes when installing flanges on the capsule. In addition, it is not only reflected in the improvement of punching speed and quality, but also through the structure to achieve stable processing of flexible materials such as aerostat capsules, providing a reliable engineering solution for the large number of punching needs for metal flange installation.

[0024] The potential energy of the energy storage spring is released to drive the punch to impact quickly. The punching speed is determined by the spring elastic coefficient and the degree of force storage, and is not affected by the operator's fatigue, thus achieving a stable and uniform punching process and greatly reducing burrs on the hole edges. The operator only needs to rotate the tool handle to complete the force storage, without the need for continuous pressure application, which reduces labor intensity and adapts to the needs of large-scale punching scenarios.

[0025] During the punching force accumulation stage, the pressure plate moves with the tool handle through the elastic pull rod, gradually clamping the capsule to ensure that the position of the capsule is fixed during punching and avoid displacement caused by impact. The elastic pull rod can adjust the clamping force synchronously with the rotation of the tool handle to ensure that the clamping part fixes the capsule with the same force before each punching, reducing the random deviation of the hole position and improving the matching accuracy between the hole position and the metal flange.

[0026] The clamp body is provided with a second channel parallel to the first channel (the movement path of the punch), and the elastic pull rod slides in cooperation with the second channel to ensure that the pressure plate only moves in the axial direction (perpendicular to the surface of the capsule) when the tool handle moves, thereby avoiding uneven clamping or local stretching deformation of the capsule due to lateral deviation.

[0027] The guide column at one end of the elastic pull rod slides with the guide groove on the tool handle to convert the rotary motion of the tool handle into the axial linear motion of the elastic pull rod. The shape of the guide groove (such as linear or arc type) can be designed as a specific trajectory so that the clamping force of the pressure plate changes evenly with the rotation angle of the tool handle, avoiding damage to the capsule caused by sudden changes in the clamping force.

[0028] When the operator turns the tool handle, the guide column slides along the guide groove, and the elastic pull rod pulls the pressure plate closer to the clamp body, gradually clamping the capsule. In this process, the guide structure ensures that the opening and closing amount of the clamping part is linearly related to the rotation angle of the tool handle, which makes it easy for the operator to accurately control the clamping force by hand feel.

[0029] By replacing direct drive with energy storage, coordinating pre-clamping and linear guidance, and collaborating with a modular adjustable structure, a control process from energy storage, positioning to firing is constructed, enhancing the operation experience and drilling accuracy.

Detailed Description of the Invention

[0038] Embodiment 1

[0039] In a typical embodiment of the present invention, as Figures 1 - 6 shown, a punching device with energy storage and firing for the aerostat envelope is given.

[0040] Existing pliers-type punches rely on the speed and force of pressing the handle to punch holes. Long-term operation can easily lead to a decrease in grip strength and pressing speed, burrs on the edge of the hole, low punching efficiency and unstable quality. In addition, there is also the problem of deviation in the punching position. Based on this, the present embodiment provides a power storage and firing punching device for an aerostat capsule. The power storage and firing structure is used to allow the punch 14 to punch holes at a stable and fast speed. It is not affected by operator fatigue, can continue to operate efficiently, and greatly improves the punching efficiency. At the same time, the stable impact speed reduces the generation of burrs on the edge of the hole, ensures the quality of the punching, and reduces the subsequent processing costs. The clamping portion formed by the pressure plate 5 and the pliers body 1 clamps the capsule before punching and fixes the hole opening area, effectively avoiding the displacement of the capsule during the punching process, ensuring the accuracy of the hole opening position, and improving the hole position accuracy.

[0041] like Figures 1 - 6 As shown, the energy storage percussion punching device for the aerostat bladder mainly comprises a clamp body 1, a knife handle 22, an energy storage component, a clamp plate and a handle.

[0042] The pliers body 1 is provided with a first hole and a second hole at intervals, the first hole is slidably matched with a punching knife 14, a triggering member 10 is installed outside one axial end of the first hole, and one end of the punching knife 14 is located between the first hole and the triggering member 10; the handle 22 is rotatably mounted on the pliers body 1, and a hook 12 is rotatably mounted on one end of the handle 22, one end of the hook 12 can hook the punching knife 14 and drive the punching knife 14 to slide along the first hole, and the other end of the hook 12 can contact the triggering member 10 under the rotation drive of the handle 22 to hang The hook 12 releases the hook of the punching knife 14; the energy storage assembly includes an energy storage spring, one end of the energy storage spring is connected to the punching knife 14, and the other end is connected to the pliers body 1, so as to drive the punching knife 14 to move by rebound; the pressure plate 5 slides with the pliers body 1, and a clamping portion is formed between one end of the pressure plate 5 and the outer annular surface of one end of the first channel away from the hook 12. The pressure plate 5 is connected to an elastic pull rod that slides with the second channel, and the end of the elastic pull rod away from the pressure plate 5 slides with the pliers body 1 to change the size of the clamping portion by rotating with the pliers body 1.

[0043] Specifically, the caliper body 1 serves as the basic structure of the device, and the first hole thereon provides a sliding track for the punching knife 14 to ensure the linearity and stability of the movement of the punching knife 14. The punching knife 14 and the caliper body 1 are slidably matched through the first hole, and an energy storage spring is connected between the punching knife 14 and the caliper body 1. When the handle 22 drives the hook 12 to hook the punching knife 14 and make the punching knife 14 slide along the first hole, the energy storage spring is stretched to store elastic potential energy.

[0044] The trigger 10 is installed outside one axial end of the first channel. When the hook 12 contacts the trigger 10 under the driving of the rotation of the tool handle 22, the trigger 10 forces the hook 12 to release the hooking of the punching tool 14. At this time, the energy storage spring instantaneously releases the elastic potential energy through rebound, driving the punching tool 14 to impact and punch holes at a stable and rapid speed. It converts manual operation into mechanical energy storage and firing, avoiding the problems of unstable speed and fatigue caused by direct manual pressing.

[0045] The tool handle 22 is rotatably installed on the pliers body 1. The operator drives the movement of the hook 12 rotatably installed at one end by rotating the tool handle 22. One end of the hook 12 can hook the punching tool 14. During the rotation of the tool handle 22, the hook 12 pulls the punching tool 14 to compress the energy storage spring, realizing the energy storage process; the other end of the hook 12 moves along with the punching tool 14 under the driving of the rotation of the tool handle 22. When it moves to the position where it contacts the trigger 10, it triggers the hook 12 to release the hooking of the punching tool 14, thus completing the firing of the punching tool 14. The action mode of the tool handle 22 combined with the energy storage spring enables the operator to complete the energy storage without continuous pressing force, only by applying a rotational torque, reducing the labor intensity, and the rotation process is easier to control the energy storage degree and speed.

[0046] In addition, the pressure plate 5 is slidably matched with the pliers body 1, forming a clamping part between it and the pliers body 1 for clamping the bladder to be punched. The cutter pad 16 on the pressure plate 5 provides support and buffering for the end of the punching tool 14, avoiding direct damage to the pliers body 1 by the punching tool 14. One end of the elastic pull rod is connected to the pressure plate 5, and the other end is matched with the tool handle 22. When the tool handle 22 rotates, it drives the pressure plate 5 to slide along the pliers body 1 through the elastic pull rod. During the energy storage stage of the punching tool 14, the clamping part gradually clamps the bladder. When the punching tool 14 fires and punches holes, the pressure plate 5 and the pliers body 1 maintain the clamping state of the bladder, fixing the punching area, preventing the bladder from shifting, and improving the punching accuracy. The elastic design of the elastic pull rod can also adapt to the unevenness of the bladder surface to a certain extent, ensuring the clamping effect.

[0047] Converting manual pressing into rotational energy storage reduces the labor intensity of the operator, enabling the operator to work stably for a long time. Moreover, the stable punching quality and accuracy reduce the material waste and rework costs caused by unqualified punching, reducing the overall use cost, having good economic benefits and practicability, and being applicable to the scenario of a large number of punchings at the floating airship bladder layout site.

[0048] As Figure 2 shown, the reset spring 23 abuts between the end of the hook 12 hooking the punching tool 14 and the tool handle 22. After the hook 12 contacts the trigger 10 to release the hooking of the punching tool 14 and the punching tool 14 completes the punching action, it can push the hook 12 back to the initial position, preparing for the next energy storage, improving the operation coherence, reducing the operation steps, and enhancing the punching efficiency.

[0049] When the handle 22 drives the hook 12 to hook the punch 14 and compress the energy storage spring, the reset spring 23 provides a reverse abutment force to ensure that the hook 12 is always stably hooked with the punch 14, avoiding accidental slippage of the hook 12 due to external interference or uneven operating force, and ensuring that the energy storage spring can reach the expected compression amount each time, so that the impact force of the punch 14 remains stable each time it is fired.

[0050] The trigger member 10 is adjustably mounted on the pliers body 1. By changing its position, the timing of the hook 12 contacting the trigger member 10 can be adjusted, thereby adjusting the force accumulation stroke of the punch 14. Figure 1 and Figure 2 As shown, in order to facilitate installation, an installation cavity is provided inside the clamp body 1, and a channel is reserved at the upper part of the installation cavity for the punching knife 14 to pass through when it is installed. The upper part of the installation cavity is blocked by the clamp body upper pressure plate 9 and the upper cover 11. The trigger 10 can be a screw, a pad, etc. When a screw is used as the trigger 10, it is installed on the upper cover 11 through threaded cooperation. By rotating the screw, the distance between the screw and the first channel can be changed, thereby changing the power storage stroke. When it is necessary to punch a hole in a thicker or harder aerostat capsule material, the trigger 10 can be adjusted away from the first channel, so that the hook 12 drives the punching knife 14 to slide a longer distance, increase the compression of the energy storage spring, and increase the impact force of the punching knife 14 when firing; on the contrary, for thinner materials, the power storage stroke is shortened to avoid overshoot damage to the punching knife 14 due to excessive impact force. The punching device can be adapted to a variety of aerostat capsules of different materials and thicknesses, as well as other similar flexible materials for punching operations, without the need to replace equipment for different materials, reducing the use cost and expanding the application range of the device.

[0051] like Figure 2 As shown, the second hole parallel to the first hole on the pliers body 1 provides a sliding track for the elastic pull rod. When the handle 22 rotates to drive the elastic pull rod to move the pressure plate 5, the second hole limits the elastic pull rod to move only in the axial direction to prevent it from lateral deviation or shaking. It ensures that the pressure plate 5 can move smoothly and accurately close to or away from the pliers body 1, so that the clamping part can evenly clamp or loosen the capsule, preventing the capsule from being damaged due to uneven force on the local part of the capsule caused by the deviation of the movement of the pressure plate 5, and at the same time ensures that the punching knife 14 can vertically pass through the clamping part to punch holes every time, thereby improving the punching accuracy.

[0052] like Figure 2 As shown, a sliding fit is formed between the pressure plate 5 and the pliers body 1. In order to facilitate the resetting of the pressure plate 5 after clamping the capsule, a pressure plate spring 17 is also installed between the pressure plate 5 and the pliers body 1. The pressure plate spring 17 is compressed when the pressure plate 5 is combined to clamp the capsule. After the drilling is completed, the pressure plate 5 can be separated from the pliers body 1 with a gap to facilitate the reinsertion of the capsule.

[0053] The guide post at one end of the elastic pull rod is slidably matched with the guide groove on the tool handle 22, converting the rotational motion of the tool handle 22 into the axial linear motion of the elastic pull rod. The guide groove adopts a T-shaped groove, and the guide post at one end of the elastic pull rod forms a T-shaped slider. After the guide post is matched with the guide groove, when the guide post slides in the groove, the displacement of the elastic pull rod is in a corresponding relationship with the rotation angle of the tool handle 22, converting the rotational motion of the tool handle 22 into the axial linear motion of the elastic pull rod. Figure 4 As shown, the shape of the guide groove can be configured according to the needs, such as using a straight line, an arc shape, etc., so that the clamping force of the pressure plate 5 changes evenly with the rotation angle of the handle 22, avoiding damage to the capsule caused by a sudden change in the clamping force. The operator can accurately adjust the moving distance of the pressure plate 5 by controlling the rotation amplitude of the handle 22, thereby accurately controlling the clamping degree of the clamping part to meet the clamping requirements of capsules of different thicknesses.

[0054] The guide structure makes the movement of the pressing plate 5 more stable and controllable, reduces the shaking of the pressing plate 5 caused by improper operation or device vibration, always maintains a stable clamping of the capsule during the punching process, and further improves the accuracy and consistency of the punching.

[0055] Specifically, Figure 5 and Figure 6 As shown, the elastic pull rod is provided with a pull rod spring 20 that is retractable in the axial direction. The elastic pull rod is extended under the drive of the pliers body 1 to overcome the elastic force of the pull rod spring 20. The pull rod spring 20 on the elastic pull rod can be retracted in the axial direction. When the pressure plate 5 contacts the capsule, the handle 22 is continuously rotated, and the pull rod spring 20 is stretched. The elasticity of the pull rod spring 20 enables the pressure plate 5 to be adaptively adjusted according to the unevenness of the capsule surface, and always maintains a uniform clamping force on the capsule. Even if there are certain undulations or wrinkles on the surface of the capsule, the pressure plate 5 can fit tightly to avoid affecting the punching effect due to local clamping that is too tight or too loose.

[0056] The elastic pull rod includes a pull rod cover 21, an inner pull rod sleeve 19, and an inner pull rod 18. One end of the inner pull rod sleeve 19 is connected to the pull rod cover 21, so that a guide slide is formed in the inner pull rod sleeve 19. One end of the inner pull rod 18 is inserted into the inner pull rod sleeve 19 and forms a sliding fit with the inner pull rod sleeve 19. The other end extends to the outside of the inner pull rod sleeve 19 for connecting to the pressure plate 5. A pull rod spring 20 is installed in the inner pull rod sleeve 19 to block the relative sliding between the inner pull rod 18 and the inner pull rod sleeve 19, thereby storing force and rebounding to form the required elastic telescopic effect. Among them, the guide column is connected to the pull rod cover 21, so that the elastic pull rod is matched with the handle 22.

[0057] At the moment of firing the punch blade 14, the pull rod spring 20 can absorb part of the reaction force of the impact force, reduce the vibration of the device transmitted to the operator's hand, and reduce the fatigue of the operator. At the same time, the buffering effect of the spring can also protect the internal structure of the device and extend the service life of the device.

[0058] A moving pin is installed on the punching knife 14. The moving pin is in sliding fit with a preset slideway on the pliers body 1. The sliding direction of the moving pin along the slideway is parallel to the axis of the first hole. One end of the energy storage spring is connected to the punching knife 14 through the moving pin; the moving pin installed on the punching knife 14 is in sliding fit with the preset slideway on the pliers body 1, and the slideway direction is parallel to the axis of the first hole, forcing the punching knife 14 to move only in a straight line, effectively preventing the punching knife 14 from deflecting due to uneven force when the energy storage spring releases energy. Ensure that the punching knife 14 vertically and accurately passes through the clamping part to punch holes, avoid problems such as inclined holes and elliptical holes, and ensure the shape accuracy and position accuracy of the punched holes.

[0059] One end of the energy storage spring is connected to the punching knife 14 through the moving pin, and the other end is connected to the pliers body 1 through the fixed pin, forming a stable tensile force transmission path. In this embodiment, as Figure 3 shown, there are two energy storage springs, namely the first energy storage spring 3 and the second energy storage spring 25, and there are two fixed pins and two moving pins respectively, which are distributed on both sides of the punching knife 14, namely the first fixed pin 4 and the second fixed pin 26, the first moving pin 2 and the second moving pin 24. One end of the first energy storage spring 3 is connected to the first fixed pin 4 and the other end is connected to the first moving pin 2, which is located on one side of the punching knife 14. One end of the second energy storage spring 25 is connected to the second fixed pin 26 and the other end is connected to the second moving pin 24, which is located on the other side of the punching knife 14.

[0060] The sliding of the moving pin in the slideway ensures that the energy storage spring is always linearly stressed during the compression and release processes, avoiding spring distortion, deformation or detachment, and ensuring the reliability and stability of the energy storage and firing processes.

[0061] The installation cavity in the pliers body 1 provides a stable rotation space for the tool holder 22. The tool holder 22 is installed in the installation cavity through a mounting small or other rotating components, reducing the friction and resistance during rotation, making the rotation of the tool holder 22 smoother. At the same time, the installation cavity integrates components such as the hook 12 and the return spring 23 inside, making the device structure more compact, effectively preventing the components from being damaged by external interference or collision during operation, and improving the reliability and safety of the device.

[0062] The first handle 6 on the pliers body 1 and the second handle 8 on the tool holder 22 adopt an ergonomic design. The operator can hold the first handle 6 with one hand to fix the pliers body 1, and hold the second handle 8 with the other hand to rotate the tool holder 22. The two-handed operation method can make the force more uniform and stable, or the single-handed holding and pressing method can be adopted. The two-handed cooperation operation is convenient for precisely controlling the rotation angle and force of the tool holder 22, improving the accuracy and efficiency of punching.

[0063] Inside the sliding sleeve 15 on the pliers body 1, a first channel is formed. Its material usually has good wear resistance and self-lubricity, such as a copper sleeve. The sliding sleeve 15 provides a high-precision sliding channel for the punching knife 14, reducing the friction between the punching knife 14 and the pliers body 1, reducing the wear of the punching knife 14, and extending the service life of the punching knife 14. In addition, the sliding sleeve 15 is installed on the pliers body 1 as an independent component. If there is wear or damage, it can be replaced conveniently and quickly, reducing the maintenance cost and difficulty of the device, and ensuring the continuous and stable operation of the device.

[0064] Embodiment 2

[0065] In another typical embodiment of the present invention, as Figures 1 - 6 shown, a working method of a power storage and percussion punching device for an aerostat envelope is given, using the power storage and percussion punching device for an aerostat envelope as in Embodiment 1.

[0066] A working method of a power storage and percussion punching device for an aerostat envelope includes:

[0067] Arrange the envelope in the clamping part, and the position to be punched corresponds to the knife pad 16;

[0068] Drive the knife handle 22 to rotate. The knife handle 22 drives the hook 12 to hook one end of the punching knife 14, driving the punching knife 14 to gradually approach the trigger 10 and pulling the energy storage spring to store energy; at the same time, the knife handle 22 drives the pressure plate 5 to move through the elastic pull rod, so that the pressure plate 5 cooperates with the pliers body 1 to clamp the envelope in the clamping part;

[0069] When the knife handle 22 continues to rotate until the hook 12 contacts the trigger 10, the hook 12 releases the hook on the punching knife 14. The punching knife 14 moves under the action of the energy storage spring, and the end penetrates into the clamping part to punch the envelope;

[0070] After the punching is completed, the knife handle 22 rotates back to its original position, the pressure plate 5 releases the clamping of the envelope, the hook 12 resumes the hook on the head end of the punching knife 14, the envelope is taken out, and the punching of the next hole position is carried out.

[0071] By adjusting the distance between the trigger 10 and the first channel, the triggering position of the hook 12 is changed, and by adjusting the specification parameters of the energy storage spring, the impact speed and impact force of the punching knife 14 acting on the envelope are changed.

[0072] Specifically, in combination with Figures 1 - 6 , the working method is described in detail.

[0073] Place the bladder in the clamping part, and align the position to be punched with the cutter pad 16. The cutter pad 16 serves as the supporting surface for the impact of the punching cutter 14. The design of its position in cooperation with the clamping part ensures that the punching cutter 14 is evenly stressed during punching, avoiding damage to the bladder due to local stress concentration. At the same time, the pre-positioning function of the clamping part enables the operator to avoid manually supporting the bladder during the punching process, reducing the interference of human operation on the punching position.

[0074] When the driving handle 22 rotates, the device realizes the synchronous dual functions of "energy storage" and "clamping". The handle 22 drives the hook 12 to hook one end of the punching cutter 14, making the punching cutter 14 gradually approach the trigger 10. During this process, the energy storage spring is pulled and compressed to store elastic potential energy. At the same time, the handle 22 drives the pressing plate 5 to move through the elastic pull rod, and the pressing plate 5 cooperates with the pliers body 1 to clamp the bladder. Through synchronous actions, the rotational motion of the handle 22 is converted into the linear motion of the elastic pull rod through the guide post-guide groove structure, thereby controlling the clamping force of the pressing plate 5. This process not only improves the operation efficiency, but more importantly, fixes the bladder during the energy storage stage of the punching cutter 14, providing stable working conditions for subsequent punching and avoiding hole position deviation caused by bladder movement.

[0075] When the handle 22 continues to rotate until the hook 12 touches the trigger 10, the hook 12 releases the hook on the punching cutter 14, and the energy storage spring instantly releases the stored elastic potential energy, driving the punching cutter 14 to move quickly, and its end penetrates into the clamping part to punch the bladder. The trigger 10 forcibly disengages the hook of the hook 12 through a mechanical structure, ensuring that the punching cutter 14 impacts the bladder at a constant speed and force. Compared with direct manual pressing, the firing process is more stable and the impact force is more controllable, effectively reducing the generation of burrs on the hole edge and improving the punching quality.

[0076] After punching is completed, the handle 22 rotates and resets. Under the action of the reset spring 23, the hook 12 resumes the hook on the head end of the punching cutter 14, preparing for the next punching. At the same time, the pressing plate 5 releases the clamping of the bladder under the action of the elastic pull rod and the pull rod spring 20, and the operator can take out the bladder and punch the next hole position. II. Technical Value and Practical Application of Parameter Adjustment

[0077] By adjusting the distance between the trigger 10 and the first hole to change the trigger position of the hook 12. In practical applications, aerostat bladders may use materials with different thicknesses and materials, such as polyamide, polyester film, etc., and their anti-puncture properties vary. By adjusting the position of the trigger 10, the energy storage stroke of the punching cutter 14 can be changed. When processing thicker or harder materials, increase the distance between the trigger 10 and the first hole, increase the compression amount of the energy storage spring, and the punching cutter 14 obtains a greater impact force; conversely, when processing thinner materials, shorten the distance to reduce the impact force and avoid material damage. Without replacing the device hardware, only by simple structural adjustment can it adapt to various working conditions, improving the versatility of the device.

[0078] Adjusting the specification parameters of the energy storage spring (such as elastic coefficient, initial compression amount, etc.) can directly change the impact speed and impact force of the punching knife 14 acting on the bladder. Energy storage springs of different specifications are suitable for different punching requirements. Springs with a high elastic coefficient can provide a stronger impact force and are suitable for hard materials; springs with a low elastic coefficient are suitable for softer materials to prevent material tearing caused by excessive impact. In addition, by adjusting the initial tensile / compression amount of the spring, the firing force of the punching knife 14 can be finely adjusted within a certain range, further optimizing the punching effect, enabling the device to accurately match the characteristics of various aerostat bladders, ensuring stable and reliable punching quality, and meeting the strict requirements for the processing accuracy of parts in the aerospace field.

For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
