[0028] In order to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings.
[0029] In Example 1 of the clamp for ships of the present invention:
[0030] like Figure 1 As shown, the ship clamp in this embodiment includes a base plate 1 and two sets of clamping units mounted on the base plate 1. The two sets of clamping units are slidably mounted on the base plate 1, allowing the two sets of clamping units to move closer or farther from each other, facilitating the clamping of workpieces of varying lengths. Furthermore, the two sets of clamping units also provide for more stable clamping of workpieces. It is worth noting that in this embodiment, fixing plates are provided at the four corners of the base plate 1 for securing the workpieces. These fixing plates are provided with fixing holes for fasteners such as bolts.
[0031] like Figure 1 and Figure 4 As shown, the structures of the two groups of clamping units are the same, and the following structural description is made by taking one group of the clamping units as an example. The clamping unit includes a mounting plate 2 arranged on the base plate 1 and a placement table 3 arranged on the mounting plate 2. A first main clamping plate 41 and a second main clamping plate 42 for clamping the workpiece are arranged on both sides of the placement table 3. The mounting plate 2 and the base plate 1 are fitted with sliding guides. Specifically, a second guide groove 11 extending along the length direction is provided on the base plate 1, and three second guide grooves 11 are provided. A second slider 23 and a guide block 24 are provided on the mounting plate 2 for guiding in the second guide groove 11. The second slider 23 is located in the second guide groove 11 at the center, and the guide blocks 24 are respectively arranged in the two second guide grooves 11 at the edges, so that the movement of the mounting plate 2 on the base plate 1 can only be along the length direction of the base plate 1. A second bidirectional threaded rod 12 is positioned within the central second guide groove 11. Two threaded segments with opposite rotation directions are located at either end of the second bidirectional threaded rod 12. A threaded hole is provided on the second slider 23 of the mounting plate 2 to engage with the second bidirectional threaded rod 12. Rotating the second bidirectional threaded rod 12 allows the two mounting plates 2 to be moved closer or further apart, improving movement efficiency. Notably, the second slider 23 is shaped to prevent it from slipping out of the second guide groove 11.
[0032] like Figure 2 and Figure 3As shown, to facilitate clamping of the workpiece, the first main plate 41 and the second main plate 42 of the clamping unit are slidably mounted on the mounting plate 2. Specifically, the first main plate 41 and the second main plate 42 are separately mounted on the placement table 3. A first guide groove 21 is provided on the surface of the mounting plate 2 along the length of the mounting plate 2. Two first guide grooves 21 are provided. The mounting plate 2 is also provided with a first bidirectional threaded rod 22 that passes through the two first guide grooves 21. The ends of the first bidirectional threaded rod 22 are provided with first and second thread segments with opposite rotation directions. The first thread segment passes through one of the first guide grooves 21, and the second thread segment passes through the other first guide groove 21. The first main plate 41 corresponds to one of the first guide grooves 21, and the second main plate 42 corresponds to the other first guide groove 21. First sliders 46 are also provided at the bottoms of the first main plate 41 and the second main plate 42, respectively corresponding to the first guide grooves 21 at their respective locations. This allows the first main plate 41 and the second main plate 42 to move closer or further apart during the rotation of the first bidirectional threaded rod 22, simplifying operation. Of course, in other embodiments, an independent driving mechanism may be provided for each of the first and second main plates. It is worth noting that the first and second bidirectional threaded rods 22 and 12 in this embodiment may be manually actuated, or, in other embodiments, may be driven by a motor.
[0033] In order to better clamp the workpiece, the placement table 3 includes a placement table body 31 fixedly arranged on the mounting plate 2 and a placement plate 33 located above the placement table body 31. The cross-section of the placement table body 31 is U-shaped, which facilitates the protection of the workpiece. The side surfaces on both sides of the placement table body 31 are at a certain angle, which can also guide the workpiece when placing it. An elastic member is provided between the placement table body 31 and the placement plate 33. Specifically, in this embodiment, the elastic member is a spring telescopic rod 32, which can avoid a large impact on the placement table 3 when placing the workpiece. A plurality of parallel and spaced anti-slip grooves 34 are provided on the surface of the placement plate 33, which can make closer contact with the workpiece during use to prevent the workpiece from sliding.
[0034] A first auxiliary plate 45 is provided on the first main plate 41, and a second auxiliary plate is provided on the second main plate 42. The connection between the first auxiliary plate 45 and the second main plate 42 is described as an example. A groove is provided at the upper end of the first main plate 41, into which the first auxiliary plate 45 is embedded. A guide hole is also provided on the first main plate 41, and a guide post 44 is provided on the first auxiliary plate 45 to fit within the guide hole. A first threaded push rod 43 is also rotatably provided on the first auxiliary plate 45. The first threaded push rod 43 is threadedly mounted on the first main plate 41 and partially extends onto the outer surface of the first main plate 41. Rotating the first threaded push rod 43 pushes the first auxiliary plate 45 relative to the first main plate 41, thereby facilitating secondary clamping of the workpiece and providing stable gripping of the workpiece. Specifically, during the clamping process, the first auxiliary plate 45 and the second auxiliary plate are in direct contact with the workpiece. To prevent clamping failure due to interference between the first main plate 41 and the second main plate 42, a clearance groove is provided at the lower end of the first main plate 41 to clear the placement table body 31. This allows the first auxiliary plate 45 and the second auxiliary plate to protrude beyond the first main plate 41 and the second main plate 42. To facilitate clamping, anti-slip grooves 34 are also provided on the first auxiliary plate 45 and the second auxiliary plate.
[0035] In the process of clamping the workpiece, first, the distance between the two sets of clamping units is adjusted according to the length of the workpiece, and then the workpiece is placed on the placement table 3 of the two sets of clamping units. Then, the spacing between the first main clamping plate 41 and the second main clamping plate 42 is adjusted so that at least one of the first main clamping plate 41 and the second main clamping plate 42 is in close contact with the workpiece. Finally, the position of the first auxiliary plate 45 and the second auxiliary plate is adjusted so that the first auxiliary plate 45 and the second auxiliary plate can clamp the workpiece. The arrangement of the first two-way threaded rod 22 and the second two-way threaded rod 12 facilitates quick adjustment, and since the auxiliary plates on the two sets of clamping units can be adjusted separately, even if the surface of the workpiece is irregular and its center line cannot be placed in the center of the placement table 3, clamping can be achieved by adjusting the auxiliary plate on one side.
[0036] It should be understood that the embodiments described are only a portion of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
