Technical Field
[0001] This utility model relates to the field of water heater technology, specifically to a gripping device for the inner tank of multi-diameter water heaters. Background Technology
[0002] The inner tank of a water heater consists of two parts: the inner tank body and the top cover. The inner tank body is usually made of stainless steel, which has excellent corrosion resistance, high temperature and high pressure resistance, and can operate for a long time under high temperature and pressure without deformation or cracking. During the assembly of the inner tank, the inner tank body and the top cover need to be pressed together through an assembly and pressing process. It is essential to ensure that the top cover does not have quality defects such as uneven pressing, cracking, wrinkling, or deformation after pressing. After the inner tank body and the top cover are pressed together, a gripping device is needed to move them to another position. However, traditional automatic gripping devices can only grip inner tank bodies of a specific size. The gripping effect is poor for inner tank bodies of different sizes, and the size of the gripping plate cannot be easily changed according to the diameter of the inner tank body, thus reducing the applicability and flexibility of the gripping device.

[0018] Reference Figures 1 to 5 As shown, this utility model provides a gripping device for the inner tank of a multi-diameter water heater, including: a main fixing plate 3 and a main slider 7. A fixing assembly 1 is fixedly connected to the main fixing plate 3 via a cylinder 2. A dual-head motor 14 is fixedly connected inside the main fixing plate 3 via a groove, and the two ends of the groove are symmetrically connected to a transmission rod 6 via bearings. The transmission rod 6 is connected to the corresponding output shaft of the dual-head motor 14 via a coupling. A storage groove 11 is opened on the lower surface of the main fixing plate 3, and a mounting plate 15 is fixedly connected to the lower opening of the storage groove 11. A through-hole is symmetrically opened on the surface of the mounting plate 15, and a buffer column 12 is movably connected inside the through-hole. An electromagnet 13 is fixedly connected to the lower end of the buffer column 12, and a spring is fixedly connected to the upper end of the buffer column 12. At the same time, the two ends of the main fixing plate 3 are symmetrically connected to the auxiliary fixing plate 4. The auxiliary fixing plate 4 has a main slide groove 17 inside, and the two ends of the auxiliary fixing plate 4 are symmetrically connected to the side plates 16. The side is movably connected to the adjusting screw 5 through the bearing. The adjusting screw 5 is connected to the transmission rod 6 through the bevel gear. The main slider 7 is slidably connected in the main slide groove 17 through the screwed adjusting screw 5. The lower surface of the main slider 7 is fixedly connected to the moving plate 8, and the surface of the moving plate 8 is fixedly connected to the clamping plate 9. At the same time, the surface of the clamping plate 9 is symmetrically connected to the auxiliary plate 10.
[0019] In this embodiment, when the inner tank of the water heater (not shown in the figure) is located directly below the main fixing plate 3 and the auxiliary fixing plate 4, the switch of cylinder 2 is activated. The telescopic rod of cylinder 2 pushes the fixedly connected main fixing plate 3 downward, and the main fixing plate 3 can simultaneously push the auxiliary fixing plate 4 and the clamping plate 9 downward, so that the clamping plate 9 can be suspended on both sides of the inner tank of the water heater. The switch of the dual-head motor 14 is activated. The output shaft of the dual-head motor 14 drives the corresponding transmission rod 6 to rotate through the coupling. The transmission rod 6 drives the corresponding adjusting screw 5 to rotate synchronously through the meshing bevel gears. Then, the two sets of main sliders 7 symmetrically screwed at both ends of the adjusting screw 5 can drive the corresponding moving plate 8 and the clamping plate 9 to move relative to each other, so that the clamping plate 9 can resist... The inner tank of the water heater is clamped on both sides. With the cooperation of the inclined surface of the clamping plate 9 and the auxiliary plate 10, the inner tank of the water heater moves upward in the vertical plane. Then, the upper surface of the inner tank of the water heater will first contact the electromagnet 13. The upper surface of the inner tank of the water heater will push the buffer column 12 to move upward synchronously through the electromagnet 13, squeezing the corresponding spring. This allows the multiple sets of electromagnets 13 set below the main fixing plate 3 to abut against the upper surface of the inner tank of the water heater. When the same switch of the multiple sets of electromagnets 13 is activated, the electromagnets 13 are energized and adsorb and fix the inner tank of the water heater, thereby completing the gripping process of the gripping device on the inner tank of the water heater, which facilitates the workers to transfer the inner tank of the water heater accordingly.
[0020] As a preferred embodiment, the main fixing plate 3 has a rectangular structure, and the storage groove 11 opened on the lower surface of the main fixing plate 3 has a square structure. The top of the storage groove 11 is opened with a storage hole corresponding to the position of the spring. The storage hole has a cylindrical structure, and the size of the storage hole is larger than the size of the spring.
[0021] In this embodiment, as Figure 1 and Figure 3 The opening of the buffer groove allows the electromagnet 13 to smoothly push the buffer post 12 upward, while the opening of the storage hole can effectively protect the compressed spring, prevent the spring from being excessively compressed by the buffer post 12, and reduce the chance of the spring being damaged.
[0022] In a preferred embodiment, the mounting plate 15 has a square structure, and multiple sets of through openings are opened parallel and equally spaced on the surface of the mounting plate 15. All sets of through openings have a square structure, and the dimensions of the through openings and the buffer post 12 are compatible. The buffer post 12 has a cuboid structure, and the baffle fixedly connected to the upper surface of the buffer post 12 has a square structure.
[0023] In this embodiment, as Figure 1 , Figure 2 and Figure 3The through-hole and the size of the buffer post 12 are matched, which helps to enhance the stability of the buffer post 12 when it moves. The overall size of the electromagnet 13 is matched with the size of the lower surface of the buffer post 12. At the same time, wiring grooves are opened inside the buffer post 12 and the main fixing plate 3 to facilitate the laying of corresponding lines. The baffle can effectively prevent the buffer post 12 from accidentally leaving the through-hole.
[0024] In a preferred embodiment, there are two sets of auxiliary fixing plates 4. Both sets of auxiliary fixing plates 4 are rectangular in structure. The auxiliary fixing plates 4 and the main fixing plate 3 are combined to form an I-shaped structure. The two sets of side plates 16 fixedly connected to both ends of the auxiliary fixing plates 4 are square in structure. Meanwhile, the adjusting screw 5 movably connected to the side plates 16 is located inside the main slide groove 17.
[0025] In this embodiment, as Figure 1 , Figure 2 and Figure 3 The two ends of the main slide groove 17 are connected to the end faces of the two ends of the auxiliary fixing plate 4, which facilitates the loading and unloading of the main slide block 7. The side setting allows the adjusting screw 5 to be smoothly installed in the main slide groove 17 opened in the auxiliary fixing plate 4, thereby ensuring that the main slide block 7 can be slidably connected in the main slide groove 17 through the screwed adjusting screw 5.
[0026] In a preferred embodiment, the main slide groove 17 on the lower surface of the auxiliary fixing plate 4 has an elongated structure, and the cross-section of the main slide groove 17 has a convex structure. The main slider 7 and the main slide groove 17 are matched in size, and the movable plate 8 fixedly connected to the lower surface of the main slider 7 has a rectangular structure.
[0027] In this embodiment, as Figure 1 , Figure 2 and Figure 4 The main slider 7 and the main slide groove 17 are matched in size, which can help enhance the stability of the main slider 7, the moving plate 8 and the clamping plate 9 when they move, thereby helping to enhance the gripping effect of the clamping plate 9 on the inner tank of the water heater.
[0028] In a preferred embodiment, the clamping plate 9 has a hollow right-angled triangular prism structure, and the vertical plane of the clamping plate 9 is fixedly connected to the moving plate 8. The width of the clamping plate 9 is greater than the width of the moving plate 8. At the same time, multiple sets of auxiliary plates 10 are fixedly connected to the inclined surface of the clamping plate 9 at equal intervals along the width direction.
[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 4The hollow structure of the clamping plate 9 can effectively reduce the weight of the clamping plate 9 itself, thereby helping to reduce the overall weight of the gripping device. At the same time, the inclined structure of the clamping plate 9 allows the inner tank of the water heater to move vertically upward by the push of the inclined surface during the process of the clamping plate 9 abutting against the inner tank of the water heater, so that the inner tank of the water heater can make full contact with the electromagnet 13, enhancing the gripping effect of the gripping device.
[0030] In a preferred embodiment, the auxiliary plate 10 has a semi-cylindrical structure, and the length of the auxiliary plate 10 is less than the length of the inclined surface of the clamping plate 9.
[0031] In this embodiment, as Figure 1 , Figure 4 and Figure 5 The structure of the auxiliary plate 10 can effectively reduce the contact area between the inner tank of the water heater and the inclined surface of the clamping plate 9, thereby reducing the resistance of the clamping plate 9 in pushing the inner tank of the water heater along the length of the inclined surface of the clamping plate 9, and helping to improve the gripping efficiency of the gripping device.
[0032] This utility model's gripping device for multi-diameter water heater inner tanks utilizes the cooperation of a main fixing plate 3, a secondary fixing plate 4, a main slider 7, a moving plate 8, a clamping plate 9, a buffer column 12, and an electromagnet 13. This allows the gripping device to stably grip water heater inner tanks of different sizes, thereby enhancing the flexibility and practicality of the device. Furthermore, the gripping device can initially clamp and fix the water heater inner tank using the clamping plate 9, and after the main fixing plate 3 is moved down to a suitable position, the electromagnet 13 below the main fixing plate 3 can fully abut against the surface of the water heater inner tank for initial adsorption and fixation. The dual gripping and fixing structure of this device further enhances its gripping effect.
