Description

Technical Field

[0001] This utility model relates to the field of explosive composite technology, and in particular to an explosive composite positioning device. Background Technology

[0002] Explosive bonding, often referred to as explosive welding, involves placing a prepared composite plate on a substrate, then laying a layer of explosives on the composite plate. The instantaneous ultra-high pressure and ultra-high speed impact energy generated during the explosion of the explosives are used to achieve solid metallurgical bonding between the metal layers.

[0003] Before explosive lamination, the cladding plate must be precisely aligned and laid with the substrate. The essence of this dimensional requirement and laying operation is to ensure that the cladding plate completely covers the target lamination area and maintains uniform parallel gaps. Currently, alignment and laying are done manually, which greatly increases workload and affects efficiency. Furthermore, manual alignment and laying may introduce deviations. Utility Model Content

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. Therefore, one objective of this invention is to propose an explosive composite positioning device, which, compared to traditional manual alignment and laying methods, significantly reduces the labor intensity of operators and improves work efficiency.

[0005] The explosive composite positioning device proposed in this utility model includes a base plate, a cover plate on the top of the base plate, and supports at both the left and right ends of the base plate. Moving rods are slidably connected to the left and right sides inside the supports. A clamping plate that fits against the base plate and the cover plate is fixed to the top of the moving rod. A rotating shaft that is rotatably connected to the center of the support is inserted through it. A toothed groove is opened on one side of each of the two moving rods. A gear that meshes with the toothed groove is sleeved on the outer surface of the rotating shaft.

[0006] A protective cover is fixed at the center of the top of the bracket. A worm gear located inside the protective cover is fitted on the outer surface of the rotating shaft. A worm gear meshing with the worm gear is rotatably connected inside the protective cover. A rotating handle is fixed at the end of the worm gear away from the protective cover.

[0007] Preferably, the left and right inner walls of the bracket are provided with guide grooves, and the surface of the movable rod is fixed with a guide rod that cooperates with the guide groove.

[0008] Preferably, the bracket is fixed with wheels at all four corners of its bottom.

[0009] Preferably, a pair of push handles are fixed to one side of the bracket.

[0010] Preferably, a slot is provided between the moving rod and the clamping plate to facilitate the retraction of the moving rod.

[0011] Preferably, the clamping plate has a rubber pad that fits against the substrate on its inner side.

[0012] The beneficial effects of this invention are as follows: The worm gear transmission mechanism and rack and pinion transmission structure enable the clamping and positioning of the substrate. The movement of the moving rod is precisely controlled by the worm and worm wheel, and the meshing of the gear and tooth groove further ensures the movement accuracy of the moving rod, allowing the cover plate to be instantly positioned simply by placing it on the substrate, providing reliable positioning assurance for the explosive lamination process. Simultaneously, the worm gear transmission mechanism has self-locking properties, automatically maintaining a locked state after the clamping plate clamps the substrate, eliminating the need for additional fixing devices and making operation simple and convenient.

[0020] Reference Figure 1-6The explosive composite positioning device includes a base plate 1, with a cover plate 2 on top of the base plate 1. Supports 3 are provided at both ends of the base plate 1, and movable rods 4 are slidably connected to the inside of each support 3. A clamping plate 16, which fits against the base plate 1 and the cover plate 2, is fixed to the top of each movable rod 4. A rotating shaft 5, rotatably connected to the center of each support 3, is inserted through the support 3. Gears 6 are provided on one side of each movable rod 4, and gears 7 meshing with the gears 6 are fitted on the outer surface of the rotating shaft 5. When the rotating shaft 5 rotates, the gears 7 rotate within the gears 6, causing the movable rods 4 to slide, thereby enabling the clamping plate 16 to clamp or release the base plate 1.

[0021] A protective cover 8 is fixed at the top center of the bracket 3. A worm gear 9 is fitted onto the outer surface of the rotating shaft 5, located inside the protective cover 8. A worm 10, meshing with the worm gear 9, is rotatably connected inside the protective cover 8. A rotating handle 11 is fixed to the end of the worm 10 away from the protective cover 8. The rotation of the rotating shaft 5 is driven by the transmission mechanism of the worm gear 9 and the worm 10. By turning the handle, the operator drives the worm 10 to rotate, which in turn drives the worm gear 9 and the rotating shaft 5 to rotate, thereby achieving precise adjustment of the position of the moving rod 4. This worm gear 9 and worm 10 transmission method has self-locking properties, which can maintain a self-locking state after the moving rod 4 clamps the cover plate 2, ensuring the stability of the substrate 1 in positioning and providing reliable positioning guarantee for explosive bonding.

[0022] The protective cover 8 is fixed at the top center of the bracket 3, which protects the worm gear 9 and worm 10 and prevents external debris from entering and affecting the transmission accuracy and service life.

[0023] The left and right inner walls of the bracket 3 are provided with guide grooves 12, and the surface of the moving rod 4 is fixed with a guide rod 13 that cooperates with the guide grooves 12. This guide structure ensures the straightness and stability of the moving rod 4 during movement, avoids the clamping plate 16 from shifting or shaking when clamping or releasing the cover plate 2, and improves the positioning accuracy.

[0024] The four corners of the bottom of the bracket 3 are all fixed with wheels 14, which facilitates the movement of the entire device within the work area.

[0025] A pair of push handles 15 are fixed to one side of the bracket 3. The operator can easily push the device to move using the push handles 15, improving work efficiency.

[0026] A slot is provided between the moving rod 4 and the clamping plate 16 to facilitate the retraction of the moving rod 4. This design allows the moving rod 4 to retract completely into the bracket 3.

[0027] A rubber pad that fits against the substrate 1 is provided on the inward side of the clamping plate 16. This increases the friction during clamping and ensures that the substrate 1 remains stable during positioning, without slipping or displacement.

[0028] In actual use of this explosive composite positioning device, the base plate 1 is first placed on a flat working surface. Next, the operator moves the device next to the base plate 1 using the push handle 15, and uses the flexibility of the wheels 14 to accurately position the device. Then, the operator turns the crank handle, which, through the transmission of the worm gear 10 and worm wheel 9, drives the rotating shaft 5 to rotate, causing the gear 7 to rotate within the tooth groove 6, pushing the moving rod 4 to slide inward along the guide groove 12 and guide rod 13. This secures the pressure plate against the two corners of the base plate 1. Then, the clamping plates 16 at the four corners of the base plate 1 complete the positioning, placing the cover plate 2 on top of the base plate 1 for precise positioning. At this time, the self-locking property of the worm gear 10 and worm wheel transmission mechanism ensures that the clamping plates 16 remain clamped. After positioning, the crank handle is turned in the opposite direction, causing the clamping plates 16 to slide outward, releasing the base plate 1, allowing for subsequent operations and processing.
