[0002] In the forklift industry, the forklift overhead guard welding is a crucial component of the forklift overhead guard system. Before welding the overhead guard, the overhead guard welding must first be fully welded. Because the overhead guard welding requires welds at multiple angles, it necessitates multiple flips on the machining platform during welding. This process is complex, difficult, time-consuming, and inefficient. Furthermore, the flipping process can easily scratch the workpiece surface, affecting the product's appearance quality.

[0006] The upper limit structure is fixedly connected to the upper part of the support frame; it is used to limit the upward tilting limit of the top frame welding. The lower limit structure is fixedly connected to the support frame and is located below the upper limit structure; it is used to limit the downward pressure limit of the top frame welding.

[0007] The support structure, located between the upper limit structure and the lower limit structure, cooperates with either the upper limit structure or the lower limit structure to support the welding of the top frame.

[0008] According to this utility model, the support frame further includes a first side plate arranged in parallel and a rectangular tube fixedly arranged between the two.

[0009] According to this utility model, the rectangular tubes are arranged in two parallel positions, one located slightly below the first side plate and the other located slightly above the first side plate, for connecting and fixing the two first side plates to form a supporting frame structure.

[0010] According to this utility model, the upper limit structure is further fixedly connected to the rectangular tube located above it.

Detailed Implementation

[0024] The technical solution of this utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of this utility model will become clearer from the following description. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown in the embodiment of this application, a forklift top frame welding and flipping frame is provided to realize the position change during top frame welding. The top frame welding structure includes a rear crossbeam a, a crossbeam e, multiple parallel connecting plates b disposed between the two and fixedly connected at both ends to either the rear crossbeam a or the crossbeam e, a rectangular plate c parallel to the rear crossbeam a and fixedly connected to the connecting plates b, and second side plates d disposed at both ends of the crossbeam e, with the second side plates d pointing towards the rear crossbeam a. The welds requiring full welding in this process include weld A connecting the rear crossbeam a and the connecting plate b, weld B connecting the connecting plate b and the crossbeam e, and weld C connecting the connecting plate b and the rectangular plate c. The flip-welding frame includes two parallel first side plates 1 and a rectangular tube 3 fixedly disposed between them. The rectangular tube 3 consists of two parallel tubes, one located slightly below the first side plate 1 and the other slightly above it, used to connect and fix the two first side plates 1 to form a supporting frame structure. The first side plate 1 is a plate-like structure, with a lower limiting plate 4, corresponding to its thickness, welded to the middle of one end face. The lower limiting plate 4 is square. A support strip 11, extending in the same direction as the lower limiting plate 4, is also formed on the same end face of the first side plate 1. The support strip 11 is located above the lower limiting plate 4 and extends longer than the lower limiting plate 4. An upper limiting plate 5 is fixedly connected to the middle of the surface of the upper rectangular tube 3, extending in the same direction as the lower limiting plate 4. Four reinforcing plates 2 are fixedly connected to the connection points between the first side plate 1 and the lower rectangular tube 3, serving to strengthen the structure. Specifically, the reinforcing plates 2 are triangular plates with right angles, arranged in pairs at both ends of the rectangular tube 3. Each pair of reinforcing plates 2 is positioned opposite each other on the opposite surfaces of the rectangular tube 3. The two right-angled sides of the reinforcing plates 2 are fixedly connected to the outer circumference of the first side plate 1 and the rectangular tube 3, respectively, thus fixing the rectangular tube 3 and the first side plate 1 structurally and preventing wobbling. The use of a triangular plate structure further increases the overall strength.

[0026] like Figure 4As shown, the flip welding frame, through the cooperation of the support bar 11 of the first side plate and the upper limit plate 5, welds and fixes the top frame at the position of the first change position in the figure, that is, the rear crossbeam a rests on the top surface of the upper limit plate 5, and the support bar 11 passes through the gap between two adjacent connecting plates b and is located at the bottom of the rectangular plate c, so as to fix the welding position of the top frame. At this time, the welding of the connecting weld A between the rear crossbeam a and the connecting plate b and the connecting weld B between the connecting plate b and the crossbeam e can be carried out.

[0027] like Figure 5 As shown, the flip welding frame, through the cooperation of the support bar 11 of the first side plate and the lower limit plate 4, welds and fixes the top frame at the position of the second change position in the figure. That is, the crossbeam e rests on the lower limit plate 4, and the support bar 11 passes through the gap between two adjacent connecting plates b and is located at the bottom of the rectangular plate c, so as to fix the welding position of the top frame. At this time, the welding of the connecting weld C between the connecting plate b and the rectangular plate c can be carried out.

[0028] The working principle of this utility model is as follows:

[0029] This utility model is designed to assist on-site welding personnel in changing positions. Firstly, the top frame welding and the welding tilting frame work together to achieve this. Figure 4 In the state of position change one, welding is performed on the connection weld A between the rear crossbeam a and the connecting plate b, and the connection weld B between the connecting plate b and the crossbeam e; then, the on-site welding personnel change the position of the top frame welding so that the top frame welding and the welding tilting frame cooperate with each other. Figure 5 The workpiece is then moved to position two, at which point the connecting weld C between the connecting plate b and the rectangular plate c is performed. After welding, the workpiece is removed, completing the welding process. This utility model uses upper and lower limiting plates and support bars to limit the welding of the top frame. Due to its small size and small space occupation, it does not obstruct multiple welding points, facilitating welding of multiple points without frequent flipping, improving welding efficiency, and effectively solving the problem of scratching the workpiece surface during flipping, thus affecting the product's appearance quality.

[0030] The above are preferred embodiments of the present utility model. Those skilled in the art can make various changes or improvements based on this. Without departing from the overall concept of the present utility model, these changes or improvements should all fall within the scope of protection claimed by the present utility model.
