Description

Technical Field

[0001] This utility model relates to the field of welding and fixing equipment, and in particular to a fixing device for welding water tanks. Background Technology

[0002] Fire truck water tanks, as large water storage containers, are typically manufactured using welding. During manufacturing, the tank walls are usually welded in place before full welding. For full welding of fire truck water tank assemblies, a common method is to use a welding platform as a reference, welding process hooks onto the tank surface, and then using an overhead crane to rotate the tank for full welding. This method has the following drawbacks: repeated rotation on the welding platform causes severe impact to the tank surface; the process hooks welded to the tank surface require repeated welding, cutting, and grinding, resulting in scratches on the tank surface; the platform rotation is at a fixed angle (usually 90 degrees), making it difficult to operate in certain areas, requiring workers to use stirrups for assistance, resulting in low welding efficiency and increased welding time.

[0019] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0020] It should be noted that many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0021] Furthermore, it should be understood in the description of this utility model that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral unit; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. However, specifying a direct connection indicates that the two connected entities do not have a connecting structure to establish a connection relationship, but are simply connected to form a whole through a connecting structure. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] In this utility model, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this utility model. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0024] In this utility model, such as Figure 1-3As shown, a fixing device for welding a water tank is provided, including two oppositely arranged fixing seats 1. The two fixing seats 1 are respectively equipped with a fixing frame 2 that can rotate around a set horizontal axis and a driving member that drives the fixing frame 2 to rotate. One end of the fixing frame 2 is provided with a telescopic clamping rod 3 and the other end is provided with a fixing rod 4. The fixing device also includes a clamping plate 5 disposed inside the clamping rod 3 and a pressure plate 6 disposed inside the fixing rod 4. The clamping plate 5 can be pressed against the surface of the water tank 7 by the clamping rod 3.

[0025] The welding fixing device of this utility model, when performing welding, such as Figure 1 As shown, first rotate the fixing frame 2 so that the clamping rod 3 faces upward and the pressure plate 6 faces downward. Then move the water tank 7 to the upper side of the pressure plate 6. At this time, the clamping rod 3 retracts to press the clamping plate 5 onto the surface of the water tank 7 for fixation, thus completing the fixation of the water tank 7. When the worker is welding, the fixing frame 2 can be rotated by the driving component to adjust the position of the water tank 7, which facilitates the worker's welding operation and improves welding efficiency.

[0026] This utility model uses a pressure plate 6 and a clamping plate 5 to clamp and fix the water tank 7. The clamping plate 5 can provide a more uniform clamping force to the water tank 7, so that the clamping rod 3 can provide a more balanced fixing force to the spot-welded water tank 7 through the clamping plate 5. It can also prevent the clamping rod 3 from applying concentrated force on the water tank 7, which could cause local deformation of the water tank 7 wall or instability of the spot weld.

[0027] In the illustrated embodiment, to further specify the structure of this utility model, the clamping rod 3 is rotatably mounted at the end of the fixed frame 2, and a telescopic rod 8 is provided between the fixed frame 2 and the clamping rod 3. The telescopic rod 8 is hinged to the fixed frame 2 and the clamping rod 3 respectively.

[0028] As shown in the figure, the extension and retraction of the telescopic rod 8 can drive the rotation of the clamping rod 3, thereby completing the extension and retraction of the clamping rod 3. In a specific embodiment, the telescopic rod 8 is configured as a pneumatic telescopic rod 8.

[0029] In the illustrated embodiment, to further specify the structure of this utility model, the clamping rod 3 is provided with a connecting seat 302 that is hinged to the fixing frame 2 at a section away from the clamping plate 5, and the telescopic rod 8 is hinged to the side of the connecting seat 302 away from the clamping plate 5 on the clamping rod 3.

[0030] As shown in the figure, the telescopic rod 8 is located on the outside of the fixed frame 2, and extends vertically when the clamping plate 5 is facing upwards. The rotational arm of the clamping rod 3 at one end of the telescopic rod 8 is smaller than the rotational arm at the end facing the clamping plate 5, so that a small extension and retraction of the telescopic rod 8 can drive a large rotation of the clamping rod 3.

[0031] In the illustrated embodiment, to further specify the structure of this utility model, the fixing device also includes a pad disposed between the fixing frame 2 and the clamping rod 3, the pad being disposed on the side of the clamping rod 3 with its rotation axis facing the clamping plate 5.

[0032] As shown in the figure, by setting up a pad, when the telescopic rod 8 drives the clamping rod 3 to rotate and press the clamping plate 5, the pad can limit the pressing force of the clamping rod 3 on the clamping plate 5, so as to prevent the clamping rod 3 from excessively clamping the clamping plate 5 and causing excessive local stress on the water tank 7.

[0033] In the illustrated embodiment, more specifically regarding the structure of this utility model, the pad includes an adjusting screw 9 threaded onto the fixing frame 2.

[0034] As shown in the figure, when clamping and fixing the water tank 7, the operator can clamp the clamping plate 5 onto the surface of the water tank 7 by rotating the adjusting screw 9, so that the adjusting screw 9 is pressed against the clamping rod 3, thereby limiting the further rotation of the clamping rod 3 toward the water tank 7. With this setting, during the full welding process, while the telescopic rod 8 is continuously loaded to keep the water tank 7 fixed, the deformation of the water tank 7 caused by excessive extension and retraction of the telescopic rod 8 can be prevented.

[0035] In the illustrated embodiment, more specifically regarding the structure of this utility model, the driving component includes a geared motor 10 connected to the fixed frame 2.

[0036] In the illustrated embodiment, more specifically regarding the structure of this utility model, the clamping plate 5 and the clamping rod 3 are separate structures; one end of the clamping plate 5 has a limiting part 11 that abuts against the outer end face of the water tank 7.

[0037] As shown in the figure, when fixing the water tank 7, the limiting part 11 of the clamping plate 5 can be made to abut against the side of the water tank 7 first, and then the clamping rod 3 can be retracted to press the clamping plate 5 against the surface of the water tank 7.

[0038] In the illustrated embodiment, for the structure of this utility model, more specifically, the clamping plate 5 includes two spaced longitudinal stiffening plates 501 and a connecting plate 502 connecting the two longitudinal stiffening plates 501.

[0039] As shown in the figure, by setting two longitudinal stiffeners 501, the structural stability of the clamping plate 5 in its length direction can be improved. This allows the clamping plate 5 to stably and evenly transmit the clamping force to the water tank 7 when the clamping rod 3 provides clamping force to the clamping plate 5.

[0040] In the illustrated embodiment, the connecting plate 502 is disposed at the bottom of the two longitudinal stiffeners 501, which can further improve the uniformity of pressure transmission from the clamping plate 5 to the water tank 7.

[0041] In the illustrated embodiment, for the structure of this utility model, more specifically, the end of the clamping rod 3 is provided with a pressure block 301, and a support plate 503 is provided between the two longitudinal stiffeners 501, with the pressure block 301 pressing against the support plate 503.

[0042] As shown in the figure, when the clamping rod 3 presses the clamping plate 5, the clamping rod 3 applies pressure to the support plate 503 between the two longitudinal stiffening plates 501 through the pressure block 301. This can prevent the pressure of the clamping rod 3 from being concentrated on one of the longitudinal stiffening plates 501, which would cause uneven force on the clamping plate 5 and thus prevent the clamping plate 5 from shifting or flipping.

[0043] In the illustrated embodiment, specifically regarding the structure of this utility model, the pressure block 301 is configured as an arc-shaped pressure block 301, and the support plate 503 is configured as an arc-shaped support plate 503. As shown in the figure, this prevents relative sliding between the pressure block 301 and the support plate 503 after the water tank 7 is clamped and fixed by the clamping plate 5 and the pressure plate 6, thereby further improving the stability of fixing the water tank 7.

[0044] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0045] The above description is merely an embodiment of this application and is not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
