Description

Technical Field

[0001] This invention relates to the field of door cover leveling technology, specifically a leveling machine for correcting door cover deformation. Background Technology

[0002] A hydraulic press (a type of hydraulic press) is a machine that uses specialized hydraulic oil as its working medium and a hydraulic pump as its power source. The pump forces the hydraulic oil through hydraulic lines into the cylinder / piston. Inside the cylinder / piston are several sets of mating seals, each with different features, all serving the purpose of sealing and preventing hydraulic oil leakage. Finally, a check valve circulates the hydraulic oil in the tank, causing the cylinder / piston to perform work and thus complete a specific mechanical action, thus contributing to productivity.

[0003] During ship repairs, as part of routine maintenance, a large number of rubber grooves for watertight doors and covers are repaired. After the repairs, these items are often deformed, requiring leveling using a hydraulic press. Because watertight doors and covers are heavy, multiple workers are needed to move them to the hydraulic press platform. After leveling, workers also need to move and unload the watertight doors and covers again. This process not only increases the labor intensity of the workers but also reduces the efficiency of subsequent work. Summary of the Invention

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-7 A leveling machine for correcting door cover deformation includes a hydraulic press body 1. Several first auxiliary rollers 2 are rotatably connected to the bottom surface of the inner side of the hydraulic press body 1 to facilitate sliding of the door cover. A groove 3 is provided between adjacent first auxiliary rollers 2, and a support plate 5 for supporting the door cover is movably connected inside the groove 3. Multi-stage electric push rods 4 are fixedly connected to both sides of the rear inner cavity of the hydraulic press body 1. The output ends of the multi-stage electric push rods 4 are fixed to the rear of the support plate 5. A fixing frame 7 is fixedly connected to the right side of the hydraulic press body 1. First screws 8 are rotatably connected to both the front and rear sides of the fixing frame 7 and the hydraulic press body 1. The surface of the first screws 8 is threaded with lifting mechanisms for lifting the door cover. Above the plate 9 and the fixed frame 7, there is a drive structure 11 for driving the two first screws 8 to rotate. The fixed frame 7 is movably connected to the inside of the first connecting plate 14. The other end of the first connecting plate 14 is fixedly connected to the first push plate 15 for pushing the door cover. The fixed frame 7 is provided with a moving structure 16 for driving the first connecting plate 14 to move. The inner surface of the hydraulic press body 1 is provided with a moving groove 17. The inside of the moving groove 17 is slidably connected to the rack plate 18. The left end of the rack plate 18 is fixedly connected to the second connecting plate 19. The other end of the second connecting plate 19 is fixedly connected to the second push plate 20. The surface of the moving structure 16 is provided with a transmission structure 21 for driving the rack plate 18 to move.

[0037] The drive structure 11 includes a first motor 111, a first timing wheel 112, and a second timing wheel 113. The first motor 111 is mounted above the fixed frame 7. The output shaft of the first motor 111 is fixed to one side of the first timing wheel 112. The surface of the first timing wheel 112 is connected to the second timing wheel 113 via a timing belt. The bottoms of the first timing wheel 112 and the second timing wheel 113 are respectively fixed to the tops of two first screws 8. When the door cover is placed on top of the lifting plate 9, the first motor 111 can be started, which drives the first timing wheel 112 to rotate, and at the same time drives the second timing wheel 113 to rotate, which in turn drives the two first screws 8 to rotate, and drives the lifting plate 9 to lift the door cover upward.

[0038] The moving structure 16 includes a second motor 161, a second screw 162, and a screw sleeve 163. The second motor 161 is located on the right side of the back of the fixed frame 7. The output shaft of the second motor 161 is fixed to one end of the second screw 162, and the other end of the second screw 162 is rotatably connected to the right side surface of the hydraulic press body 1. The surface of the second screw 162 is threadedly connected to the inside of the screw sleeve 163, and the bottom of the screw sleeve 163 is fixed to the other end of the first connecting plate 14. Thus, when the lifting plate 9 is raised to be parallel to the platform of the hydraulic press body 1, the second motor 161 can be started, which drives the second screw 162 to rotate. At the same time, the screw sleeve 163 moves to the left side of the surface of the second screw 162, thereby driving the first connecting plate 14 and the first push plate 15 to move together, thereby pushing the door cover placed on the top surface of the lifting plate 9.

[0039] The transmission structure 21 includes a first bevel gear 211, a second bevel gear 212, a rotating rod 213, and a gear disk 214. The first bevel gear 211 is fixed to the surface of the second screw 162. The right side surface of the first bevel gear 211 meshes with the surface of the second bevel gear 212. The other side of the second bevel gear 212 is fixed to one end of the rotating rod 213. The surface of the rotating rod 213 is rotatably connected to the interior of the fixed frame 7. The other end of the rotating rod 213 is fixed to one side of the gear disk 214. The top surface of the gear disk 214 meshes with the bottom surface of the rack plate 18. When the second screw 162 rotates, it drives the first bevel gear 211 to rotate. As the first bevel gear 211 rotates, it drives the second bevel gear 212, the rotating rod 213, and the gear disk 214 to rotate, thereby driving the rack plate 18 to move to the left.

[0040] Movable grooves 12 are provided on the front and back sides of the right side surface of the hydraulic press body 1. Movable blocks 13 are slidably connected inside the movable grooves 12. The other end of the movable blocks 13 is fixed to the bottom of the lifting plate 9. This can provide auxiliary limit for the lifting plate 9 and facilitate its up and down movement.

[0041] The top surface of the lifting plate 9 is rotatably connected with several second auxiliary rollers 10, which reduces the friction between the door cover and the top surface of the lifting plate 9, making it easier to push the door cover through the first push plate 15 later.

[0042] A limiting plate 22 is fixedly connected to the back of the rack plate 18. The surface of the limiting plate 22 is slidably connected to the inside of the moving groove 17, so as to provide auxiliary support for the rack plate 18 and maintain its stability during movement.

[0043] The inside of the fixed frame 7 is provided with a limiting groove 6. The surface of the first connecting plate 14 is in contact with the inner wall of the limiting groove 6 and is slidably connected to its inner wall. This can help limit the first connecting plate 14 and maintain its stability when moving.

[0044] The top surface of the support plate 5 is flush with the top surface of the first auxiliary roller 2. Thus, when the door cover is located on the top surface of the first auxiliary roller 2, the support plate 5 can support the door cover and prevent the first auxiliary roller 2 from being damaged under force during leveling.

[0045] Support blocks 23 are fixed at the front and rear of the bottom right side of the lifting plate 9, and the bottom surface of the support blocks 23 is flush with the bottom of the hydraulic press body 1. This can provide auxiliary support for the lifting plate 9 and improve its stability when placing the door cover.

[0046] Working principle: In use, first, place the door cover to be leveled on the top surface of the lifting plate 9. Then, the drive structure 11 drives the first screw 8 to rotate, causing the lifting plate 9 to move upward until the top surface of the lifting plate 9 is level with the placement table surface of the hydraulic press body 1. Next, the moving structure 16 drives the first connecting plate 14 and the first push plate 15 to move to the left, so that the first push plate 15 pushes the door cover on the top surface of the lifting plate 9 to the left. With the drive of the moving structure 16, the transmission structure 21 can drive the rack plate 18 to move to the left until the door cover is located on the top surface inside the hydraulic press body 1. Then, the machine can be started. The multi-stage electric push rod 4 is activated, which moves the support plate 5 forward, causing the support plate 5 to slide into the interior of the slide groove 3, thereby supporting the door cover. Afterwards, the door cover can be leveled by the hydraulic press body 1. After leveling, the multi-stage electric push rod 4 first moves the support plate 5 out of the interior of the slide groove 3. Then, the moving structure 16 moves the first connecting plate 14 and the first push plate 15 to the right. Then, through the transmission structure 21, the rack plate 18, the second connecting plate 19 and the second push plate 20 are also moved to the right, and the door cover is pulled from the bottom of the inside of the hydraulic press body 1 to the top surface of the lifting plate 9, so that it can be unloaded later.
