Description

Technical Field

[0001] This invention relates to the field of clamping device technology, and more particularly to a clamping device for processing thin plates for cruise ships. Background Technology

[0002] A cruise ship is a passenger vessel used for recreational sailing. The voyage, destinations along the way, and onboard facilities are all part of the tourism and entertainment experience. In an era where air travel is widespread, transportation is no longer the primary purpose of cruise ships. Although some routes are one-way, cruise ships typically return passengers to their point of departure, thus serving as both transportation and accommodation / dining facilities. During the fabrication process, the thin plates used in cruise ship construction require clamping devices for positioning.

[0003] For example, in the grinding process of thin metal sheets, existing clamping devices are generally fixed at a certain position on the upper and lower surfaces of the sheet. As a result, the clamping device will block the surface of certain parts of the sheet. Therefore, it is necessary to first remove the sheet from the clamping device and then fix it back on the clamping device, which is very inconvenient. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a clamping device for processing thin plates for cruise ships.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A clamping device for processing thin plates for cruise ships includes a base plate and a thin plate body. A first support plate and a second support plate are respectively installed at the upper ends of the base plate. A support seat is installed at the upper end of the first support plate and the second support plate. A movable seat is slidably connected above the support seat. A first clamping plate is connected to one end of the movable seat. A second clamping plate is provided below the first clamping plate. The second clamping plate is connected to the movable seat through a height adjustment mechanism. The thin plate body is placed between the first clamping plate and the second clamping plate.

[0007] The movable seat is connected to the support seat via a locking mechanism, and the second support plate is connected to the base plate via a horizontal adjustment mechanism.

[0008] Preferably, the height adjustment mechanism includes a connecting plate, which is fixedly connected to the second clamping plate. A rack is fixed to one side of the second clamping plate, and a gear is meshed with one side of the rack. The gear is rotatably connected to the movable seat through a connecting shaft, and a knob is fixed to one end of the connecting shaft.

[0009] Preferably, a plurality of ball sleeves are installed at equal intervals below the first clamping plate and above the second clamping plate, and ball bearings are rotatably connected inside the ball sleeves.

[0010] Preferably, the locking mechanism includes a first cavity and a groove. A pressure plate is slidably connected in the first cavity. A plurality of first damping teeth are fixed at equal intervals in the groove. A fixing rod is fixedly connected above the first damping teeth. A second spring is sleeved on the outside of the fixing rod between the pressure plate and the first cavity. A second damping tooth is fixed at one end of the fixing rod.

[0011] Preferably, the connecting shaft is connected to the movable seat through an anti-rotation mechanism. The anti-rotation mechanism includes a fixed block, a connecting rod slidably connected to the fixed block, a clamping block and a handle fixed at both ends of the connecting rod, and a first spring sleeved on the outside of the connecting rod. The two ends of the first spring are fixedly connected to the clamping block and the fixed block, respectively.

[0012] Preferably, the inner diameter of the clamping block is adapted to the outer diameter of the connecting shaft, and a rubber pad is fixed on the inner side of the clamping block.

[0013] Preferably, the support base has symmetrical first sliding grooves on both sides, and the lower end of the movable base is fixed with a slider that is slidably connected to the first sliding groove.

[0014] Preferably, the horizontal adjustment mechanism includes a lead screw, a second slide groove, and a limiting rod. The lead screw is rotatably connected to the base plate, and a threaded sleeve is threaded onto the surface of the lead screw. The threaded sleeve is fixedly connected to the second support plate via a support rod. A handwheel is fixed to one end of the lead screw. The support rod is slidably connected to the second slide groove, and the second support plate is slidably connected to the limiting rod.

[0015] Preferably, a cylinder is fixed to the surface of the fixing rod, and a telescopic rod is connected between two adjacent cylinders.

[0016] Preferably, the interior of the movable seat has a second cavity and a third cavity respectively corresponding to the positions of the connecting plate and the gear. The longitudinal section of the connecting plate has an "L" shape, and the cross section of the connecting plate has a "T" shape.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. By setting up a first clamping plate, a second clamping plate and a height adjustment mechanism, turning the knob clockwise will drive the gear to rotate clockwise through the connecting shaft, causing the rack to move upward gradually. This will cause the second clamping plate to move upward gradually through the connecting plate until the balls located above and below simultaneously press against the upper and lower surfaces of the thin plate body, thus achieving the clamping of the thin plate body.

[0019] 2. By setting a locking mechanism, when the pressure plate is pulled up so that it does not contact the thin plate body, the thin plate body can be pulled to change the blocking position of the first clamping plate and the second clamping plate on the thin plate body, so that the worker can perform more comprehensive grinding on the thin plate body. In addition, when the second damping tooth is not engaged with the first damping tooth, the moving seat can be pulled to change the distance between the two moving seats, making it more suitable for thin plate bodies of different widths, thereby making the fixing effect of the thin plate body more stable.

[0020] 3. By setting up a horizontal adjustment mechanism and rotating the handwheel, the screw is rotated. Since the screw sleeve is threadedly connected to the screw, and the limiting rod plays a limiting role on the second support plate, the distance between the second support plate and the first support plate can be changed, so that this device is suitable for clamping thin plates of different lengths.

Detailed Implementation

[0029] 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.

[0030] Reference Figure 1-7 A clamping device for processing thin plates for cruise ships includes a base plate 1 and a thin plate body 33. A first support plate 2 and a second support plate 3 are respectively installed at the upper ends of the base plate 1. Support seats 4 are installed at the upper ends of both the first support plates 2 and 3. A movable seat 5 is slidably connected above the support seats 4. First grooves 6 are symmetrically formed on both sides of the support seats 4. A slider 7 is fixed to the lower end of the movable seat 5 and slidably connected to the first groove 6. The slider 7 slides within the first groove 6, limiting the movement of the movable seat 5 and preventing it from detaching from the support seats 4. A first clamping plate 8 is connected to one end of the movable seat 5. A second clamping plate 9 is located below the first clamping plate 8 and is connected to the movable seat 5 via a height adjustment mechanism. The thin plate body 33 is placed between the first clamping plate 8 and the second clamping plate 9. Multiple ball sleeves 10 are installed at equal intervals below the first clamping plate 8 and above the second clamping plate 9. Ball bearings 11 are rotatably connected inside the ball sleeves 10. The height adjustment mechanism includes a connecting plate 12, which is fixedly connected to the second clamping plate 9. A rack 13 is fixed to one side of the second clamping plate 9, and a gear 14 is meshed with one side of the rack 13. The gear 14 is rotatably connected to the moving seat 5 through a connecting shaft 15. A knob 16 is fixed to one end of the connecting shaft 15. Rotating the knob 16 clockwise causes the connecting shaft 15 to drive the gear 14 to rotate clockwise, causing the rack 13 to gradually move upward. This, in turn, gradually drives the second clamping plate 9 to move upward through the connecting plate 12, until the ball bearings 11 located above and below simultaneously press against the upper and lower surfaces of the thin plate body 33, thus achieving initial clamping of the thin plate body 33.

[0031] The movable seat 5 is connected to the support seat 4 via a locking mechanism. The locking mechanism includes a first cavity 23 and a groove 26. A pressure plate 22 is slidably connected in the first cavity 23. Multiple first damping teeth 27 are fixed at equal intervals in the groove 26. A fixing rod 24 is fixedly connected above the first damping teeth 27. A second spring 25 is sleeved on the outside of the fixing rod 24 between the pressure plate 22 and the first cavity 23. A second damping tooth 28 is fixed to one end of the fixing rod 24. The first damping teeth 27 and the second damping teeth 28 are made of elastic plastic material, such as ABS (acrylonitrile-butadiene-styrene copolymer) and POM (polyoxymethylene). When the pressure plate 22 presses against the thin plate body 33, it can further fix the thin plate body 33. When the pressure plate 22 is pulled up so that it does not contact the thin plate body 33, the thin plate body 33 can be pulled, changing the obstruction position of the first clamping plate 8 and the second clamping plate 9 on the thin plate body 33, so that the worker can perform more comprehensive grinding on the thin plate body 33. When the second damping tooth 28 engages with the first damping tooth 27, the position of the movable seat 5 on the support seat 4 is fixed; when the second damping tooth 28 no longer engages with the first damping tooth 27, the movable seat 5 can be pulled to change the distance between the two movable seats 5, making it more suitable for thin plate bodies 33 of different widths, thereby making the fixing effect of the thin plate body 33 more stable.

[0032] The connecting shaft 15 is connected to the movable seat 5 through an anti-rotation mechanism. The anti-rotation mechanism includes a fixed block 17, on which a connecting rod 18 is slidably connected. A clamping block 19 and a handle 21 are fixed at both ends of the connecting rod 18, and a first spring 20 is sleeved on the outside of the connecting rod 18. The two ends of the first spring 20 are fixedly connected to the clamping block 19 and the fixed block 17, respectively. The clamping block 19 clamps the connecting shaft 15, and the first spring 20 also exerts a force on the connecting shaft 15 through the clamping block 19, so that the clamping block 19 presses more tightly against the connecting shaft 15, preventing the connecting shaft 15 and the gear 14 from rotating on their own. The inner diameter of the clamping block 19 is matched with the outer diameter of the connecting shaft 15, and a rubber pad is fixed on the inner side of the clamping block 19. The rubber pad can increase the friction between the clamping block 19 and the connecting shaft 15.

[0033] The second support plate 3 is connected to the base plate 1 via a horizontal adjustment mechanism. The horizontal adjustment mechanism includes a lead screw 34, a second slide groove 38, and a limiting rod 39. The lead screw 34 is rotatably connected to the base plate 1, and a threaded sleeve 35 is threaded onto the surface of the lead screw 34. The threaded sleeve 35 is fixedly connected to the second support plate 3 via a support rod 36. A handwheel 37 is fixed to one end of the lead screw 34. The support rod 36 is slidably connected to the second slide groove 38, and the second support plate 3 is slidably connected to the limiting rod 39. By rotating the handwheel 37, the distance between the second support plate 3 and the first support plate 2 can be changed due to the threaded connection between the threaded sleeve 35 and the lead screw 34, and the limiting rod 39 limiting the second support plate 3. This is suitable for thin plate bodies 33 of different lengths.

[0034] A cylinder 29 is fixed to the surface of the fixed rod 24. A telescopic rod 30 is connected between two adjacent cylinders 29. The telescopic rod 30 can realize the synchronous movement of two adjacent fixed rods 24, and at the same time, it also allows the distance between two adjacent movable seats 5 to change.

[0035] The interior of the movable seat 5 has a second cavity 31 and a third cavity 32 respectively at the positions corresponding to the connecting plate 12 and the gear 14. The longitudinal section of the connecting plate 12 is "L" shaped and the cross section of the connecting plate 12 is "T" shaped. The connecting plate 12 slides in the second cavity 31, which limits the connection plate 12 itself and prevents the connecting plate 12 from detaching from the movable seat 5.

[0036] In this invention, the distance between the two support seats 4 is adjusted according to the length of the thin plate body 33. By rotating the handwheel 37 in the forward direction, the screw 34 rotates in the forward direction. Since the screw sleeve 35 is threadedly connected to the screw 34, and the limiting rod 39 limits the second support plate 3, the distance between the second support plate 3 and the first support plate 2 can be gradually increased, which is suitable for thin plate bodies 33 with longer lengths. Conversely, by rotating the handwheel 37 in the reverse direction, the screw 34 rotates in the reverse direction, which can be used to gradually decrease the distance between the second support plate 3 and the first support plate 2, which is suitable for thin plate bodies 33 with shorter lengths.

[0037] Initially, the distance between the first clamping plate 8 and the second clamping plate 9 is relatively large. The two ends of the thin plate body 33 are placed between the two sets of first clamping plates 8 and second clamping plates 9 respectively. With the second spring 25 in the anti-loosening state, the pressure plate 22 is slightly lower than the lower end of the ball bearing 11 located on the first clamping plate 8. Then, the handle 21 is pulled, and under the action of the connecting rod 18, the clamping block 19 disengages from the connecting shaft 15. The first spring 20 is compressed, and the knob 16 is rotated clockwise. The connecting shaft 15 drives the gear 14 to rotate clockwise, causing the rack 13 to gradually move upwards. This, in turn, gradually drives the second clamping plate 9 through the connecting plate 12. Move upwards until the upper and lower balls 11 simultaneously press against the upper and lower surfaces of the thin plate body 33. Then, release the handle 21. Under the rebound action of the first spring 20 and the auxiliary clamping plate 19, the connecting shaft 15 is re-clamped, thereby preventing the connecting shaft 15 and gear 14 from rotating on their own. Furthermore, the pressure plate 22 is subjected to the upward force of the thin plate body 33, causing the pressure plate 22 to move into the first cavity 23. The second spring 25 is compressed. At the same time, the second spring 25 will also cause the pressure plate 22 to exert a reaction force on the thin plate body 33, pressing the thin plate body 33, thereby fixing the thin plate body 33.

[0038] The distance between the two movable seats 5 on the same support base 4 can also be adjusted according to the width of the thin plate body 33. By holding the telescopic rod 30 and pulling it upward, the two fixed rods 24 can be pulled upward simultaneously through the connecting action of the telescopic rod 30. The fixed rod 24 drives the second damping tooth 28 to move upward, so that the second damping tooth 28 is no longer engaged with the first damping tooth 27. At this time, the movable seat 5 can be pulled (during the process of pulling the movable seat 5, since the arc surfaces of the second damping tooth 28 and the first damping tooth 27 are still in intermittent contact, a little force is required when pulling the movable seat 5), changing the distance between the two movable seats 5, making it more suitable for thin plate bodies 33 of different widths, thereby making the fixing effect of the thin plate body 33 more stable. At the same time, the fixed rod 24 will also pull the pressure plate 22 upward. The pressure plate 22 is moved so that it no longer presses against the thin plate body 33. When the movable seat 5 is pulled, since the other end of the thin plate body 33 is fixed at this time, the movable seat 5 is in a sliding state with the thin plate body 33. The ball bearing 11 rolls against the surface of the thin plate body 33, which makes the movement of the movable seat 5 smoother. The slider 7 slides in the first groove 6, which plays a limiting role for the movable seat 5 and prevents the movable seat 5 from falling off the support seat 4. When the current set of movable seats 5 is adjusted to a suitable distance, the telescopic rod 30 is lowered. Under the rebound action of the second spring 25, the pressure plate 22 presses against the thin plate body 33 again. The second damping tooth 28 meshes with the first damping tooth 27, thereby fixing the set of movable seats 5 again. The distance of the other set of movable seats 5 can be adjusted in the same way.

[0039] After adjusting the spacing between the two movable seats 5, if it is necessary to change the position of the first clamping plate 8 and the second clamping plate 9 covering the surface of the thin plate body 33, the two telescopic rods 30 can be pulled upwards again. Similarly, the four fixed rods 24 drive the four pressure plates 22 to move upwards, the second spring 25 is compressed, and the thin plate body 33 is pulled. The ball bearings 11 ensure the smoothness of the sliding between the thin plate body 33 and the first clamping plate 8 and the second clamping plate 9. Since the arc surfaces of the second damping tooth 28 and the first damping tooth 27 are still in contact... By touching the surface, the position of the movable seat 5 on the support seat 4 can remain basically unchanged, only changing the obstruction position of the first clamping plate 8 and the second clamping plate 9 on the thin plate body 33, so that the worker can perform more comprehensive grinding on the thin plate body 33. After the thin plate body 33 is pulled to the appropriate position, the telescopic rod 30 is released. Under the rebound action of the second spring 25, the pressure plate 22 presses the thin plate body 33 again, and the second damping tooth 28 also meshes with the first damping tooth 27, so that the thin plate body 33 and the movable seat 5 can be fixed again.

[0040] When it is necessary to remove the thin plate body 33, similarly, first disengage the clamping block 19 from the connecting shaft 15, then turn the knob 16 counterclockwise, and the connecting shaft 15 drives the gear 14 to rotate counterclockwise, so that the rack 13 gradually moves downward, thereby gradually driving the second clamping plate 9 to move downward through the connecting plate 12, and the thin plate body 33 can be removed.

[0041] 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 equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
