[0021] To make the purpose, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 6, the utility model provides a technical solution: an automatic centering lifting device, including a sealing plate 5, a lifting frame 1 is fixedly installed on one side surface of the sealing plate 5, a lifting table assembly 2 is slidably connected above the lifting frame 1, and two centering assemblies 3 are slidably connected between the lifting frame 1 and the sealing plate 5 on one side surface of the lifting frame 1. Each centering assembly 3 and the lifting table assembly 2 are connected to the lifting frame 1 through corresponding driving devices.

[0023] Please refer to Figure 3 and Figure 6 , the lifting table assembly 2 includes a table body 201. Both ends of the bottom surface of the table body 201 are fixedly connected with guide rods 102. Each guide rod 102 is slidably connected in a corresponding guide sleeve 101. The two guide sleeves 101 are fixedly installed on the lifting frame 1. Two lifting hydraulic cylinders 103 are also fixedly connected to the lifting frame 1. The piston rods of the two lifting hydraulic cylinders 103 are connected to the bottom surface of the table body 201.

[0024] The whole table body 201 realizes the sliding connection with the lifting frame 1 through the cooperation of the guide sleeve 101 and the guide rod 102. At the same time, it can perform independent lifting movement relative to the lifting frame 1 driven by the lifting hydraulic cylinder 103, so as to realize the adjustment of the height of the aluminum plate, so that the height of the aluminum plate can correspond to the height of the clamps on both sides of the aluminum plate stretcher.

[0025] Further, a number of uniformly distributed mounting brackets 202 are fixedly installed on the upper surface of the table body 201 along its extension direction. A roller shaft 203 is rotatably installed on the number of mounting brackets 202. A number of first rollers 204 are fixedly sleeved on the roller shaft 203. Each first roller 204 is located between two adjacent mounting brackets 202. A roller braking device 4 is also provided on one side of each first roller 204.

[0026] A number of first rollers 204 are arranged on the upper surface of the table body 201. The feeding mechanism of the aluminum plate stretcher feeds the material. The bottom of the aluminum plate contacts the surfaces of the number of first rollers 204. When the aluminum plate stretcher adjusts the position of the aluminum plate according to the width of the aluminum plate, the first rollers 204 support and guide the aluminum plate.

[0027] Further, each roller braking device 4 includes a mounting block 401. The mounting block 401 is fixedly connected to the upper surface of the table body 201 on the side corresponding to the first roller 204. A braking hydraulic cylinder 402 is fixedly installed on the mounting block 401. One end of the piston rod of the braking hydraulic cylinder 402 is connected with a brake block 404.

[0028] By driving the brake block 404 to displace through the braking hydraulic cylinder 402, the contact between the brake block 404 and the corresponding first roller 204 can be realized, so as to brake and limit the roller shaft 203 by increasing the friction force, so as to maintain the stability of the aluminum plate during the lifting process with the table body 201.

[0029] Furthermore, the brake block 404 is detachably mounted on one side surface of the mounting plate 403, and the mounting plate 403 is fixedly mounted at one end of the piston rod of the brake hydraulic cylinder 402.

[0030] The mounting plate 403 is fixedly mounted at one end of the piston rod of the brake hydraulic cylinder 402, and the brake block 404 is detachably connected to the mounting plate 403 by means of connection such as bolts, so as to facilitate the disassembly and replacement of the mounting plate 403 in the later stage and improve the convenience of overall maintenance of the device.

[0031] Please refer to Figure 4 and Figure 5 As shown in, each centering assembly 3 includes a centering frame 301. On one side surface of each centering frame 301 facing the lifting frame 1, two sets of sliders 302 distributed vertically are fixedly mounted. Each set of sliders 302 is slidably connected in the corresponding guiding chute 303. The two guiding chutes 303 are opened on one side surface of the lifting frame 1 facing the sealing plate 5 and are distributed vertically and parallel to each other. At the top end of one side surface of the centering frame 301, two extension plates 304 distributed vertically and parallel to each other are fixedly mounted. Between the opposite side surfaces of the two extension plates 304, a second roller 305 is rotatably mounted. One end of the piston rod of the centering hydraulic cylinder 306 is detachably connected to one side surface of the centering frame 301 through a connection structure. The two centering hydraulic cylinders 306 are both fixedly mounted on one side surface of the lifting frame 1.

[0032] Through the cooperation of the sliders 302 and the guiding chutes 303, the two centering frames 301 can both achieve independent lateral displacement relative to the lifting frame 1, so as to change the positions of the two second rollers 305 relative to the lifting frame 1. Each centering hydraulic cylinder 306 can drive the corresponding centering frame 301 to perform sliding displacement. Furthermore, the two centering frames 301 can perform displacement synchronously or independently, so as to be flexibly adjusted according to the width of the aluminum plate. During the horizontal displacement and centering process of the aluminum plate, the second rollers 305 are used to limit and guide it.

[0033] Furthermore, the connection structure includes a connection block 307 fixedly mounted at one end of the piston rod of the centering hydraulic cylinder 306. On one side surface of each centering frame 301, a connection seat 308 corresponding to the connection block 307 is fixedly mounted. Corresponding pin holes are opened on both the connection block 307 and the connection seat 308. A pin rod 309 is inserted into the pin holes. A card slot 310 is opened on the outer wall of one end of the pin rod 309. The card slot 310 is clamped with a pin piece 311, and the pin piece 311 is detachably connected to the connection seat 308 by bolts.

[0034] When it is necessary to separate the centering frame 301 from the piston rod of the corresponding centering hydraulic cylinder 306, remove the bolts of the connecting pin plate 311 and the connecting seat 308, and take out the pin plate 311 from the card slot 310, so that the pin rod 309 can be withdrawn from the pin holes of the connecting block 307 and the connecting seat 308, realizing the separation of the centering frame 301 and the centering hydraulic cylinder 306. Similarly, the connection between the lifting hydraulic cylinder 103 and the table body 201 can also adopt this structure, which is convenient for the overall maintenance and overhaul of the device in the later stage, and further improves the use convenience.

[0035] Working principle: The whole device is fixedly installed under the aluminum plate stretcher through the sealing plate 5. The feeding mechanism of the aluminum plate stretcher places the aluminum plate on the lifting table assembly 2. Its position detection unit detects the position of the aluminum plate, and starts two centering hydraulic cylinders 306 through the control system. The two centering frames 301 are driven by the centering hydraulic cylinders 306 to perform corresponding displacements, so that the aluminum plate is displaced to the center point position of the stretcher. Subsequently, the control system starts two lifting hydraulic cylinders 103 to drive the table body 201 to rise, so that the height of the aluminum plate is the same as the height of the stretcher clamp. Subsequently, the aluminum plate is stretched by the stretcher.

[0036] It should be noted that the specific model specifications of the lifting hydraulic cylinder 103, the centering hydraulic cylinder 306 and the braking hydraulic cylinder 402 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

[0037] The power supply and its principle of the lifting hydraulic cylinder 103, the centering hydraulic cylinder 306 and the braking hydraulic cylinder 402 are clear to those skilled in the art, and will not be elaborated here.

[0038] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
