Description

Technical Field

[0001] This invention relates to the field of equipment clamping technology, and in particular to a centering and clamping method for a projectile clamping mechanism. Background Technology

[0002] Clamping devices are common and widely used in various stages of industrial production assembly. After the attitude adjustment of the projectile (such as fire extinguishing projectiles and rain-reducing projectiles) is completed, it needs to be fixed to prevent the propulsion unit from changing its attitude, such as misalignment, tilting, or overturning, during subsequent transportation, which would affect subsequent work.

[0003] The clamping and fixing device is a mechanism that secures the propeller to the propulsion stage's attitude adjustment device by clamping the propeller adapter ring. Traditional propeller fixing methods involve creating bolt holes in the propeller adapter ring and using several sets of bolts to fasten it to the frame. While simple and reliable, this bolting method cannot achieve proper centering and clamping. Therefore, for specific working conditions requiring reloading and transportation, or other suitable industrial production scenarios, a centering and clamping method suitable for the projectile clamping mechanism needs to be developed.

[0004] Existing clamping methods typically adjust the clamping width by rotating the handle. When the width of the clamped item varies significantly, it usually requires ten or even dozens of rotations. Therefore, we need a centering clamping method for the spring-loaded clamping mechanism to solve the problems of the existing clamping methods, such as the inability to automatically center and the slow clamping speed. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide a centering and clamping method for a projectile clamping mechanism to solve the problems of inability to automatically center and slow clamping speed in existing clamping methods mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A method for centering and clamping a projectile clamping mechanism, comprising the following steps: Step 1, Projectile Placement: Place the projectile between the clamping supports; Step 2, Projectile pre-clamping: Pull the handle to achieve initial centering and pre-clamping of the projectile through the clamping push device; Step 3, Adjust the projectile's attitude: Adjust the angle of the projectile; Step 4, centering and clamping the projectile: Turn the handle clockwise to clamp the projectile and control the clamping bracket to center and lock the projectile. Step 5, disassembly of the projectile: Turn the handle counterclockwise during disassembly; Step 6, Reset of the projectile clamping mechanism: Push the handle to disassemble the projectile and reset the projectile clamping mechanism.

[0007] Furthermore, in step 2, during the process of pulling the handle, the handle drives the first rod to move horizontally along the direction of the pulling force. The movable ratchet repeatedly enters the ratchet groove under the action of the spring. When both rubber base plates on both sides touch the projectile, the handle can no longer be pulled. This step is completed, and the projectile is pre-clamped.

[0008] Furthermore, in step 3, the elasticity and friction of the rubber base plate are used to adjust the angle of the projectile, so that no additional support is needed for the projectile before and after the adjustment.

[0009] Furthermore, in step 4, during the clockwise rotation of the handle, the handle drives the first rod to rotate, and the first rod drives the external threaded rod to rotate through the rotating disk. The external threaded rod moves to one side under the action of the internal threaded cylinder, thereby driving the ball block to rotate and move to one side at the same time. The push-pull trapezoidal block moves to one side, causing the first moving slider to center and move closer to each other, so as to realize that the clamping brackets are centered and move closer to each other, thus clamping the projectile.

[0010] Furthermore, in step 5, during the counterclockwise rotation of the handle, the sidewall of the movable ratchet no longer contacts the sidewall of the ratchet groove, allowing the movable ratchet to rotate.

[0011] Furthermore, in step 6, during the process of pushing the handle, the sliding cylinder causes the movable ratchet to disengage from the ratchet groove, allowing the internal thread cylinder and the positioning cylinder to slide freely.

[0012] Furthermore, the projectile clamping mechanism employs a clamping mechanism including a clamping bracket, a first movable slider, a frame, a first fixed slider, a second slider, a push-pull trapezoidal block, and a clamping push device. The frame contains a first fixed slider, which is slidably connected to two symmetrical first movable sliders. Each movable slider has a first inclined surface, and a second slider is fixed to the first inclined surface of the first movable slider.

[0013] Furthermore, a rubber base plate is installed on one side of the clamping bracket.

[0014] Furthermore, a pressure sensor plate is installed between the clamping bracket and the rubber base plate.

[0015] Furthermore, slider limiting plates are fixed on both sides of the frame.

[0016] Furthermore, the frame has through holes on both sides.

[0019] Furthermore, both the frame and the clamping bracket have an anti-rust coating on their surfaces.

[0020] Furthermore, the clamping and pushing device includes a threaded rod, and a threaded hole is provided in the middle of the frame, with the threaded rod threadedly connected to the threaded hole.

[0021] Furthermore, the clamping and pushing device includes a positioning cylinder, an externally threaded rod, an internally threaded cylinder, a first rod body, a rotating disk, and a sliding cylinder; the positioning cylinder is fixed to one side of the frame, and an internally threaded cylinder is slidably connected inside the positioning cylinder. A quick positioning mechanism is installed between the internally threaded cylinder and the positioning cylinder, and an externally threaded rod is internally threaded to the internally threaded cylinder. A rotating disk is installed at one end of the externally threaded rod, and the first rod body is rotatably connected to the rotating disk. The tail of the internally threaded cylinder can rotate freely relative to the main body of the internally threaded cylinder, and the tail of the sliding cylinder can rotate freely relative to the main body of the sliding cylinder.

[0022] Furthermore, the free rotation between the tail end and the main body of the internally threaded cylinder and the sliding cylinder is achieved through the cooperation of the annular slider and the annular groove.

[0023] Furthermore, a handle is installed at one end of the first rod.

[0024] Furthermore, the rapid positioning mechanism includes a ratchet groove, a square groove, a movable ratchet, a spring, a limiting protrusion ring, and a sliding groove; the positioning cylinder has ratchet grooves arranged along the axial direction, the internally threaded cylinder has grooves arranged along the axial direction, the grooves have movable ratchets hinged inside, the middle of the movable ratchets is connected to the concave surface of the grooves by a spring, the internally threaded cylinder has a long through groove parallel to the grooves on one side, the long through grooves are slidably connected to a sliding cylinder, the sliding cylinder has a square groove inside, and the external side of the internally threaded cylinder is fixed with a limiting protrusion ring.

[0025] Furthermore, the outer diameter of the internally threaded cylinder between the groove and the long through groove is reduced by 6 mm.

[0026] Furthermore, an elastic telescopic pad is installed between the sidewall of the elongated groove and the sidewall of the sliding cylinder.

[0027] Furthermore, an inclined rod is fixed to the end of the sliding cylinder, and one end of a hollow rod is hinged to the end of the internally threaded cylinder. The other end of the hollow rod is slidably connected to a groove in the middle of the first rod body, and one end of the inclined rod is slidably connected to the middle of the hollow rod.

[0028] Furthermore, the tail of the internally threaded cylinder can rotate freely relative to the main body of the internally threaded cylinder, and the tail of the sliding cylinder can rotate freely relative to the main body of the sliding cylinder.

[0029] Furthermore, a rubber base plate is installed on one side of the clamping bracket.

[0030] Furthermore, the free rotation between the tail end and the main body of the internally threaded cylinder and the sliding cylinder is achieved through the cooperation of the annular slider and the annular groove.

Detailed Implementation

[0040] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0041] Example A specific embodiment of the present invention discloses a centering and clamping method for a projectile clamping mechanism, such as... Figure 5 As shown, the specific steps include: Step 1, Projectile placement: Place the projectile between the clamping brackets 2; The projectile is placed between the clamping brackets 2. There are no requirements on the specific position of the clamping brackets 2 on both sides of the projectile. Since the push-pull trapezoidal block 9 and the external threaded rod 11 are connected by a ball groove 10 and a ball block, the external threaded rod 11 can only move along the center line of the external threaded rod 11. Therefore, the push-pull trapezoidal block 9 can also only move along the center line of the external threaded rod 11. The two first moving sliders 3 connected to the inner groove of the push-pull trapezoidal block 9 by the second slider 8 can simultaneously move closer to or further away from the center line of the external threaded rod 11 by the same amount. The clamping brackets fixedly connected to the first moving sliders 3 can simultaneously move closer to or further away from the center line of the external threaded rod 11 by the same amount. Therefore, as long as the projectile is between the clamping brackets 2, the projectile can be pushed to the symmetrical surface of the clamping brackets 2 when the projectile is fixed, so as to achieve the centering and clamping of the projectile. Step 2, Projectile pre-clamping: Pull handle 13 to achieve initial centering pre-clamping of the projectile through the clamping push device; Pulling handle 13 causes the first rod 14 to move away from the frame 4. The first rod 14 drives the external thread rod 11 to move towards the frame 4 via rotating disk 15. The external thread rod 11 drives the push-pull trapezoidal block 9 to move towards the frame via the cooperation of ball groove 10 and ball block. The push-pull trapezoidal block 9 translates to the symmetrical plane of the first moving slider 3 via two opposing first moving sliders 3 that are slidably connected to it. The first moving slider 3 drives the two clamping brackets 2 to move closer to each other, thereby achieving pre-clamping of the projectile for centering. Since the external thread rod 11 and the internal thread cylinder 12 are connected by threads, the internal thread cylinder 12 is stationary relative to the external thread rod 11 when the external thread rod 11 is translated. The movable ratchet 18 installed on the internal thread cylinder 12 repeatedly enters the ratchet groove 7 opened in the positioning cylinder 6 under the action of the spring 19. Due to the unidirectional movement principle of the ratchet, the movable ratchet 18 cannot return to the ratchet groove 7 that has already been passed. Due to the presence of the limiting protrusion ring 21, the tail of the tilting rod, the hollow rod 22 and the internal threaded cylinder 12 form a stable triangle, and the sliding cylinder 16 is stationary relative to the internal threaded cylinder 12. Step 3, Adjust the projectile's attitude: Adjust the angle of the projectile; The rubber base plate 1 pre-clamps the projectile. Due to the elasticity of the rubber base plate 1 and the positional relationship between the ratchet groove 7 and the movable ratchet 18, there is a possibility that the projectile may be slightly embedded in the rubber base plate 1 or 0-2mm away from the rubber base plate 1 on both sides. If the projectile is slightly embedded in the rubber base plate 1 on both sides, the operator can adjust the clamping posture of the projectile. If the projectile is 0-2mm away from the rubber base plate 1, the operator needs to manually maintain the posture of the projectile until step 4 is completed. Step 4, centering and clamping the projectile: rotate handle 13 clockwise to clamp the projectile and control clamping bracket 2 to center and lock the projectile. Handle 13 drives the first rod 14 to rotate clockwise, the first rod 14 drives the rotating disk 15 to rotate clockwise, the rotating disk 15 drives the external thread rod 11 to rotate clockwise, the external thread rod 11 moves outward of the frame 4 under the action of the internal thread cylinder 12, the external thread rod 11 drives the push-pull trapezoidal block 9 to move to one side of the frame 4 through the cooperation of the ball groove 10 and the ball block, the push-pull trapezoidal block 9 translates to the symmetrical plane of the first moving slider 3 through the two opposing first moving sliders 3 slidably connected to it, the first moving slider 3 drives the two clamping brackets 2 to move closer to each other, so as to achieve clamping and fixing of the projectile; Step 5, disassembly of the projectile: When disassembling, turn handle 13 counterclockwise; The principle of turning handle 13 counterclockwise is the same as that of turning handle 13 clockwise, so that the movable ratchet 18 against the side wall of ratchet groove 7 can rotate. Step 6, Reset of projectile clamping mechanism: Push handle 13 to disassemble the projectile and reset the projectile clamping mechanism.

[0042] Pushing the first handle 13 causes the movable ratchet 18 to disengage from the ratchet groove 7, allowing the internal thread cylinder 12 and the positioning cylinder 6 to slide freely. Pushing the first handle 13 toward the positioning cylinder 6 resets the quick positioning mechanism. The rotation of the handle 13 toward the positioning cylinder 6 will automatically reset after the operator releases their hand once the clamping bracket 2 has reset. The reset relies on the elastic telescopic characteristics of the elastic telescopic pad 20.

[0043] Preferably, in step 2, during the pulling of handle 13, handle 13 drives the first rod 14 to move horizontally along the direction of the pulling force. The first rod 14 drives the movable ratchet 18 to repeatedly enter the ratchet groove 7 under the action of spring 19. When the rubber base plate 1 on both sides of the clamping bracket 2 touches the projectile, handle 13 can no longer be pulled. This step is completed, and the projectile is pre-clamped.

[0044] Preferably, in step 3, the elasticity and friction of the rubber base plate 1 are used to adjust the angle of the projectile, so that no additional support is needed for the projectile before and after the adjustment.

[0045] Preferably, in step 4, during the clockwise rotation of the handle 13, the handle 13 drives the first rod 14 to rotate, and the first rod 14 drives the external thread rod 11 to rotate through the rotating disk 15. The external thread rod 11 moves to one side under the action of the internal thread cylinder 12, thereby driving the ball block to rotate and move to one side at the same time, pushing and pulling the trapezoidal block 9 to one side, driving the first moving slider 3 to center and move closer to each other, realizing that the clamping bracket 2 is centered and moves closer to each other, and clamping the projectile.

[0046] Preferably, in step 5, during the counterclockwise rotation of the handle, the sidewall of the movable ratchet 18 no longer contacts the sidewall of the ratchet groove 7, allowing the movable ratchet 18 to rotate.

[0047] Preferably, in step 6, during the process of pushing the handle 13, the first rod 14 drives the hollow rod 22 to rotate, the hollow rod 22 drives the sliding cylinder 16 to slide, and the sliding cylinder 16 causes the movable ratchet 18 to disengage from the ratchet groove 7, so that the internal thread cylinder 12 and the positioning cylinder 6 can slide freely.

[0048] Preferably, the projectile clamping mechanism used in the centering and clamping method of the projectile clamping mechanism is, for example, Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, it includes a clamping bracket 2, a first movable slider 3, a frame 4, a first fixed slider 5, a second slider 8, a push-pull trapezoidal block 9, and a clamping and pushing device; the frame 4 has a first fixed slider 5 fixed inside, and the first fixed slider 5 is slidably connected to two symmetrical first movable sliders 3. The first movable slider 3 has a first inclined surface, and the first inclined surface of the first movable slider 3 is fixed with a second slider 8. The clamping bracket 2 is installed on one side of the first movable slider 3, and a slidable push-pull trapezoidal block 9 is installed between the two second sliders 8. The push-pull trapezoidal block 9 is installed on one side of the push-pull trapezoidal block 9.

[0049] The sliding trapezoidal block 9 has second sliding grooves on both sides, which cooperate with the second slider 8. When the sliding trapezoidal block 9 moves to the left or right (e.g., Figure 1 As shown), the push-pull trapezoidal block 9 drives the second slider 8 to move. The first movable slider 3 has a first movable groove, which is slidably connected to the first fixed slider 5. With the cooperation of the first fixed slider 5 and the first movable slider 3, the first movable slider 3 moves to the center or both sides, thereby driving the clamping bracket 2 to clamp or contact the object.

[0050] Preferably, a rubber base plate 1 is installed on one side of the clamping bracket 2.

[0051] The rubber base plate 1 is used to increase the friction of the object to be clamped. At the same time, when facing objects with a small clamping contact area, the rubber base plate 1 can increase the contact area of ​​the object to be clamped by slight deformation.

[0052] Preferably, a pressure sensor plate is installed between the clamping bracket 2 and the rubber base plate 1.

[0053] When dealing with soft materials that cannot withstand large clamping forces, the pressure sensor can display the clamping force on the object, thereby adjusting the clamping and locking mechanism to have sufficient clamping force while avoiding damage to the object.

[0054] Preferably, slider limiting plates are fixed on both sides of the frame 4.

[0055] Preferably, the frame 4 has through holes on both sides.

[0056] The through holes are designed to facilitate the fixing of the frame 4.

[0057] Preferably, the clamping bracket 2 and the first movable slider 3 are fixed together by bolts. When faced with items of different shapes to be clamped, and when different styles of clamping brackets 2 are required, the threaded connection makes it easy to disassemble and replace.

[0058] Preferably, the push-pull trapezoidal block 9 and the clamping and pushing device are connected by a rotating mechanism. A ball groove 10 is provided on one side of the push-pull trapezoidal block 9, and a ball block is installed in the ball groove 10. The ball block is fixedly connected to the clamping and pushing device.

[0059] As the ball rotates, it moves to one side, and the push-pull trapezoidal block 9 moves to one side along with the ball under the action of the ball groove 10.

[0060] Preferably, both the frame 4 and the clamping bracket 2 have an anti-rust coating.

[0061] The anti-rust coating is used to increase the service life of the frame 4 and the clamping bracket 2.

[0062] Preferably, the surface of the rubber base plate 1 is provided with anti-slip texture.

[0063] The anti-slip texture is designed to increase the friction of the rubber base plate 1.

[0064] Preferably, the clamping and pushing device includes a positioning cylinder 6, an external threaded rod 11, an internal threaded cylinder 12, a first rod body 14, a rotating disk 15, and a sliding cylinder 16; the positioning cylinder 6 is fixed to one side of the frame 4, the internal threaded cylinder 12 is slidably connected inside the positioning cylinder 6, a quick positioning mechanism is installed between the internal threaded cylinder 12 and the positioning cylinder 6, and the external threaded rod 11 is internally threadedly connected to the internal threaded cylinder 12. A rotating disk 15 is installed at one end of the external threaded rod 11, and the first rod body 14 is rotatably connected to the rotating disk 15. The tail of the internal threaded cylinder 12 can rotate freely relative to the main body of the internal threaded cylinder 12, and the tail of the sliding cylinder 16 can rotate freely relative to the main body of the sliding cylinder 16.

[0065] Preferably, the free rotation between the tail end and the main body of the internally threaded cylinder 12 and the sliding cylinder 16 is achieved by the cooperation of an annular slider and an annular groove. The annular slider and annular groove ensure that the first rod 14 will not be unable to rotate during its rotation around the external thread rod 11 due to the main body limitation of the internal thread cylinder 12 and the sliding cylinder 16.

[0066] The external threaded rod 11 and the internal threaded cylinder 12 work together to clamp the object to be clamped.

[0067] Preferably, a handle 13 is installed at one end of the first rod 14.

[0068] Used to increase the feel of pulling or rotating the first rod 14.

[0069] Preferably, the quick positioning mechanism includes a ratchet groove 7, a square groove 17, a movable ratchet 18, a spring 19, a limiting protrusion ring 21, and a sliding groove 23; the positioning cylinder 6 has a ratchet groove 7 arranged along the axial direction, the internally threaded cylinder 12 has a groove arranged along the axial direction, the movable ratchet 18 is hinged inside the groove, the middle part of the movable ratchet 18 is connected to the concave surface of the groove by a spring 19, the internally threaded cylinder 12 has a long through groove parallel to the groove on one side, the long through groove is slidably connected to a sliding cylinder 16, the sliding cylinder 16 has a square groove 17 inside, and the limiting protrusion ring 21 is fixed on the outside of the internally threaded cylinder 12.

[0070] The ratchet groove 7 and the movable ratchet 18 are used to quickly move the clamping bracket 2 to the vicinity of the item to be clamped. The sliding cylinder 16 and the square groove 17 are used to push the movable ratchet 18 out of the ratchet groove 7, which facilitates the reset of the clamping and locking mechanism.

[0071] Preferably, the outer diameter of the internally threaded cylinder between the groove and the elongated slot is reduced by 6 mm to facilitate the sliding of the sliding cylinder 16.

[0072] Preferably, an elastic telescopic pad 20 is installed between the sidewall of the elongated groove and the sidewall of the sliding cylinder 16.

[0073] When the elastic expansion pad 20 is not subjected to external force applied by the operator, the sliding cylinder 16 does not limit the movable ratchet 18. When the elastic expansion pad 20 receives external force applied by the operator, the sliding cylinder 16 moves to one side, pushing the movable ratchet 18 located in the ratchet groove 7 out of the ratchet groove 7, so that the internal thread cylinder 12 can slide in the positioning cylinder 6.

[0074] Preferably, an inclined rod is fixed to the end of the sliding cylinder 16, and one end of the hollow rod 22 is hinged to the end of the internally threaded cylinder 12. The other end of the hollow rod 22 is slidably connected to the groove 23 in the middle of the first rod body 14, and one end of the inclined rod is slidably connected to the middle of the hollow rod 22. The first rod 14 has a groove in the middle. One end of the hollow rod 22 is slidably connected to the groove 23. The end of the hollow rod 22 that is connected to the groove is cylindrical, so that the hollow rod can rotate and slide relative to the first rod 14. The groove 23 is used to drive the hollow rod 22 to rotate when the first rod 14 rotates.

[0075] The end of the inclined rod is slidably connected to the hollow groove of the hollow rod 22, and the end of the inclined rod used for connection is cylindrical, so that the inclined rod can slide and rotate relative to the hollow rod 22, so that the sliding cylinder 16 slides under the rotation of the hollow rod 22.

[0076] Preferably, the tail of the internally threaded cylinder 12 can rotate freely relative to the main body of the internally threaded cylinder 12, and the tail of the sliding cylinder 16 can rotate freely relative to the main body of the sliding cylinder 16.

[0077] Preferably, a pressure sensor plate is installed between the clamping bracket 2 and the rubber base plate 1.

[0078] Preferably, the free rotation between the tail of the internally threaded cylinder 12 and the sliding cylinder 16 and the main body is achieved by the cooperation of the annular slider and the annular groove.

[0079] When it is necessary to clamp and lock the item, pull the handle 13. The handle 13 drives the first rod 14 to be pulled. Due to the presence of the limiting protrusion 21, the first rod 14 cannot rotate. The first rod 14 moves in the direction of the pulling force. The first rod 14 drives the movable ratchet 18 to move in the direction of the pulling force through the rotating disk 15, the external thread rod 11 and the internal thread cylinder 12. The movable ratchet 18 repeatedly enters the ratchet groove 7 under the action of the spring 19. The principle of the movable ratchet 18 moving in the ratchet groove 7 is that the inclined surface of the ratchet groove 7 and the spring 19 make the movable ratchet 18 move in the direction of the pulling force while repeatedly moving within a certain angle range. When both rubber base plates 1 touch the object to be clamped, the handle 13 cannot be pulled. At this time, the movable ratchet 18 is in one of the ratchet grooves 7 or between two ratchet grooves 7. Pushing the rotating disk 15 causes the movable ratchet 18 to move in the opposite direction. Due to the unidirectional movement principle of the ratchet, the movable ratchet 18 in the ratchet groove 7 remains in that ratchet groove 7, and the movable ratchet 18 between two ratchet grooves 7 retracts to one of the ratchet grooves 7, thereby moving the push-pull trapezoidal block 9 to the appropriate position, and thus enabling the clamping bracket 2 to quickly approach the object to be clamped. Rotate the handle 13 in the forward direction. The handle 13 drives the external thread rod 11 to rotate through the first rod body 14 and the rotating disk 15. The external thread rod 11 rotates and moves to one side under the action of the internal thread cylinder 12, thereby driving the ball block to rotate and move to one side, pushing and pulling the trapezoidal block 9 to move to one side, thereby clamping the item.

[0080] The clamping push device for clamping items can save the number of times the handle 13 is frequently turned, shorten the time required to clamp items, and greatly improve clamping efficiency.

[0081] When it is necessary to resolve the clamping and locking of the item and reset it, rotate the handle 13 in the opposite direction three to five times to eliminate the force between the ratchet groove 7 and the movable ratchet 18, allowing movement between them. Push the handle 13 towards the positioning cylinder 6, causing the first rod 14 to rotate around the edge of the rotating disk 15. The first rod 14 drives the hollow rod 22 to rotate, which in turn pushes the tilting rod. The tilting rod drives the sliding cylinder 16 to rotate, and the wall of the sliding cylinder 16 pushes the movable ratchet 18 out of the ratchet groove 7. The limit between the internal threaded cylinder 12 and the positioning cylinder 6 disappears. Push the handle 13, which, through the action of the first rod 14, the rotating disk 15, the external threaded rod 11, the ball block, and the ball groove 10, pushes the trapezoidal push-pull block to move, thus resetting the clamping and locking mechanism.

[0082] When clamping an item using this clamping and locking mechanism, it is only necessary to pull the handle 13 (which quickly positions the clamping bracket 2 close to the item via a quick positioning mechanism) and rotate the handle 13 clockwise around the rotating disk 15 (the handle 13 drives the first rod 14 to rotate, the first rod 14 drives the rotating disk 15 to rotate, the rotating disk 15 drives the external threaded rod 11 to rotate, the external threaded rod 11 moves to one side under the action of the internal threaded cylinder 12, thereby pushing the push-pull trapezoidal block 9 to one side, and the push-pull trapezoidal block 9 drives the two clamping brackets 2 to move closer, thereby achieving centering clamping of the item). Compared with existing clamping devices, this mechanism has the advantages of significantly reducing the number of rotations of the handle 13, reducing the clamping operation time, achieving centering clamping, and increasing work efficiency in scenarios such as transfer and transportation.

[0083] After clamping an item using this clamping mechanism, the clamping mechanism needs to be reset to complete the clamping function. This can be done by rotating the handle 13 in the opposite direction around the rotating disk 15 (the principle is the same as the forward rotation); rotating the first handle 13 towards the positioning cylinder 6 (so that the movable ratchet 18 disengages from the ratchet groove 7, allowing the internal thread cylinder 12 to slide freely between the positioning cylinder 6); and pushing the first handle 13 towards the positioning cylinder 6 (so that the quick positioning mechanism is reset; the rotation of the handle 13 towards the positioning cylinder 6 will automatically reset after the clamping bracket 2 is reset and the operator releases their hand, the reset relying on the elastic telescopic pad 20's telescopic characteristics).

[0084] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.

Claims

1. A centering and clamping method for a projectile clamping mechanism, comprising the following steps: Step 1, Placement of the projectile: Place the projectile between the clamping brackets (2); Step 2, projectile pre-clamping: Pull the handle (13) to achieve preliminary centering pre-clamping of the projectile through the clamping push device; Step 3, Adjust the projectile's attitude: Adjust the angle of the projectile; Step 4, centering and clamping the projectile: rotate the handle (13) clockwise to clamp the projectile and control the clamping bracket (2) to center and lock the projectile. Step 5, disassembly of the projectile: When disassembling, turn the handle (13) counterclockwise; Step 6, Reset of projectile clamping mechanism: Push handle (13) to disassemble the projectile and reset the projectile clamping mechanism; In step 2, during the process of pulling the handle (13), the handle (13) drives the first rod (14) to move in the direction of the pulling force. The first rod (14) drives the movable ratchet (18) to repeatedly enter the ratchet groove (7) under the action of the spring (19). When the rubber base plate (1) on both sides of the clamping bracket (2) touches the projectile, the handle (13) cannot continue to be pulled. This step is completed to achieve the pre-clamping of the projectile. The clamping and pushing device includes a positioning cylinder (6), an external threaded rod (11), an internal threaded cylinder (12), a first rod body (14), a rotating disk (15), and a sliding cylinder (16).
