[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.
[0025] Specific implementation examples are given below.
[0026] like Figures 1 to 6As shown in the embodiment of this utility model, a plate-type hydraulic clamp includes a supporting base plate 1, a pair of upright plates 11 fixedly connected to the top of the supporting base plate 1; multiple hydraulic cylinders 12 are installed inside the upright plates 11; the hydraulic cylinders 12 are staggered on the upright plates 11; a connecting plate 13 is fixedly connected to the output end of the hydraulic cylinder 12; a clamp body 14 is fixedly connected to the end of the connecting plate 13; multiple lifting rings 15 are fixedly connected to the surface of the supporting base plate 1; multiple oil inlet holes 16 are opened on the side wall of the upright plates 11; the oil inlet holes 16 and the hydraulic cylinders 12 are connected; multiple oil outlet holes 17 are opened on the surface of the upright plates 11; the oil outlet holes 17 and the hydraulic cylinders 12 are connected; a base plate oil passage 18 is opened inside the supporting base plate 1; the base plate oil passage 18, the oil inlet holes 16, and the oil outlet holes 17 are all connected; multiple brackets 19 are fixedly connected to the side wall of the upright plates 11; the brackets 19 and the clamp body 14 are connected. For corresponding settings; during operation, the workpiece is first placed on the support 19, and then oil is injected through the oil inlet 16. After the oil enters the oil inlet 16, it moves to multiple oil cylinders 12 through the oil passage 18 on the base plate. When the oil enters the oil cylinder 12, the oil cylinder 12 pushes the connecting plate 13 to rotate. When the connecting plate 13 rotates, it drives the clamp body 14 to move closer to the support 19, thereby clamping and fixing the workpiece. After clamping, the oil can be extracted through the oil outlet 17. After the oil is extracted, the oil cylinder 12 will rotate the connecting plate 13 to unlock the clamping of the workpiece, which can then be removed. This allows multiple oil cylinders 12 to work at the same time. By connecting the oil inlet 16 and oil outlet 17 of multiple oil cylinders 12 in series, multiple oil cylinders 12 can be controlled simultaneously during use. This allows multiple workpieces to be clamped at the same time, making it more convenient to use.
[0027] like Figure 6 As shown, a buffer pad 2 is fixedly attached to the bottom of the connecting plate 13; the buffer pad 2 and the connecting plate 13 are correspondingly arranged; during operation, when the connecting plate 13 rotates, it will move closer to the bracket 19. At this time, the buffer pad 2 will first contact the bracket 19. When the connecting plate 13 contacts the bracket 19, it will squeeze the buffer pad 2. At this time, the buffer pad 2 will deform, thereby dispersing the impact force and thus buffering it; by adding the buffer pad 2, the flexibility of the buffer pad 2 can reduce the impact during contact when the connecting plate 13 rotates, thereby increasing protection during contact and reducing impact damage during long-term contact.
[0028] like Figure 6As shown, a protective shell 3 is fixedly connected to the side wall of the connecting plate 13; the protective shell 3 and the connecting plate 13 are correspondingly arranged; during operation, when the connecting plate 13 drives the clamp body 14 to rotate, the protective shell 3 will rotate with the connecting plate 13, thereby blocking dust and impurities in the surrounding environment when the connecting plate 13 is working, thus reducing the amount of dust entering the connection between the oil cylinder 12 and the connecting plate 13; by adding the protective shell 3, the surrounding dust can be blocked when the connecting plate 13 rotates, reducing dust adhesion during operation, thereby increasing protection.
[0029] like Figure 5 As shown, a pair of springs 4 are fitted on the surface of the lifting ring 15; the ends of the springs 4 and the base of the lifting ring 15 are fixedly connected; a slip ring 41 is fixedly connected to the ends of the springs 4; the slip ring 41 and the lifting ring 15 are slidably connected; during operation, when the support base plate 1 needs to be lifted by the lifting ring 15, the slip ring 41 can be slid first to compress the springs 4, and then the slip ring 41 is released when the lifting device contacts the lifting ring 15. At this time, the springs 4 will quickly rebound, pushing the slip ring 41 towards the lifting device, thereby clamping it by the springs 4 to reduce its range of motion during lifting; by adding springs 4, the range of motion of the lifting device can be reduced by the pushing of the springs 4 when lifting the lifting ring 15, thereby making the lifting more stable and reducing slippage.
[0030] like Figure 5 As shown, a friction pad 5 is fixedly attached to the surface of the slip ring 41; the friction pad 5 and the lifting ring 15 are slidably connected; during operation, when the slip ring 41 contacts the lifting device, the friction pad 5 will contact the lifting device first, thereby increasing the contact area through the deformation of the friction pad 5 during compression; by adding the friction pad 5, friction can be increased through the deformation of the friction pad 5 when in contact with the lifting device, thereby increasing the moving resistance and making it more stable during lifting.
[0031] like Figure 5 As shown, a dustproof cloth 6 is fitted over the surface of the spring 4; the dustproof cloth 6 and the base of the lifting ring 15 are fixedly connected; during operation, when the oil cylinder 12 is working, dust in the surrounding air will drift with the wind. When the dust drifts to the vicinity of the spring 4, the dustproof cloth 6 will provide protection for the spring 4, thereby blocking the dust; by adding the dustproof cloth 6, the amount of dust adhering to the surface of the spring 4 can be reduced when the spring 4 is working, thereby protecting the spring 4 and reducing the damage caused by dust adhesion.
[0032] Working principle: First, the workpiece is placed on the support 19, and then oil is injected through the oil inlet 16. After the oil enters the oil inlet 16, it moves to multiple oil cylinders 12 through the oil passage 18 on the base plate. When the oil enters the oil cylinder 12, the oil cylinder 12 pushes the connecting plate 13 to rotate. When the connecting plate 13 rotates, it drives the clamp body 14 to move closer to the support 19, thereby clamping and fixing the workpiece. After clamping, the oil can be extracted through the oil outlet 17. After the oil is extracted, the oil cylinder 12 will rotate the connecting plate 13 to unlock the clamping of the workpiece, which can then be removed. This allows multiple oil cylinders 12 to work at the same time. When the connecting plate 13 rotates and is fixed, it moves closer to the support 19. At this time, the buffer pad 2 will first contact the support 19. When the connecting plate 13 contacts the support 19, it will squeeze the buffer pad 2, which will deform and disperse the impact force, thus buffering the impact. When the clamp body 14 rotates, the protective shell 3 rotates along with the connecting plate 13. This blocks dust and impurities from the surrounding environment when the connecting plate 13 is working, thus reducing their entry into the connection between the cylinder 12 and the connecting plate 13. When the support base plate 1 needs to be lifted by the lifting ring 15, the slip ring 41 can be slid first to compress the spring 4. Then, when the lifting device contacts the lifting ring 15, the slip ring 41 is released, and the spring 4 will quickly rebound, pushing the slip ring 41 towards the lifting device. This clamps the slip ring 41, reducing its range of motion during lifting. When the slip ring 41 contacts the lifting device, the friction pad 5 will contact the lifting device first. This increases the contact area through the deformation of the friction pad 5 during compression. When the cylinder 12 is working, dust in the surrounding air will drift with the wind. When the dust drifts to the vicinity of the spring 4, the dustproof cloth 6 will protect the spring 4, thus blocking the dust.
[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
