Description

Technical Field

[0001] The utility model relates to the field of welding platforms, in particular to a front axle welding platform. Background Art

[0002] The front axle is a device that transmits the axial forces acting on the vehicle frame and the front wheels, as well as the resulting bending moments and torques. The front axle is connected to the vehicle frame (or monocoque) via the suspension, with wheels mounted at both ends. Vertical loads acting on the frame are transmitted to the wheels via the axle. Rolling resistance, driving force, braking force, lateral forces, and the resulting bending moments and torques on the wheels are then transmitted to the suspension and frame via the axle. Therefore, the axle's function is to transmit the axial forces acting on the frame and wheels, as well as the resulting bending moments and torques.

[0003] During the front axle welding process, welding fixtures are typically used to improve welding efficiency. For example, patent number 201110089906.1, titled "A Front Axle Assembly Welding Method and Its Specialized Front Axle Assembly Welding Fixture Clamping Device," addresses the technical challenges of existing front axle assembly welding processes, including complexity and high costs.

[0021] The following is a more detailed description of the front axle welding platform of the present invention, with reference to schematic diagrams. These schematic diagrams illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art may modify the present invention as described herein while still achieving the beneficial effects of the present invention. Therefore, the following description should be understood as a general guide for those skilled in the art and not as a limitation of the present invention.

[0022] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0023] like Figure 1 As shown, an embodiment of the present utility model proposes a front axle welding platform, which includes a base 1, a side plate positioning plate 2 and an axle hole positioning tube 3.

[0024] Specifically, the base 1 has a horizontal support surface, and the horizontal support surface is used to install the side panel positioning plate 2 and place the front axle welding plate.

[0025] Two side panel positioning plates 2 are arranged in parallel, and the two side panel positioning plates 2 are fixedly mounted on the base 1 . The tops of the two side panel positioning plates 2 are penetrated by an axial positioning hole 4 that matches the axial hole positioning tube 3 .

[0026] The axis hole positioning tube 3 is inserted into the two axis center positioning holes 4 , and the axis hole positioning tube 3 is used to perform axis center positioning on the front axle welding plate.

[0027] In this embodiment, when welding the front axle plate, the front axle vertical plate is placed between the two side plate positioning plates 2. The axle hole positioning tube 3 is then passed through the axle center positioning hole 4, the front axle vertical plate hole, and the axle center positioning hole 4 in sequence. The front axle vertical plate hole and the axle center positioning hole 4 are now coaxially arranged. Simultaneously, the front axle vertical plate can slide along the length of the axle hole positioning tube 3. Once the front axle vertical plate is successfully aligned with the base plate at the welding position, the front axle vertical plate can be welded to the base plate.

[0028] In a specific embodiment, a plurality of support plates 5 are provided on the horizontal support table, and the plurality of support plates 5 are distributed in a straight line. The support plates 5 are located between the two side plate positioning plates 2, and a positioning bar 6 is provided on the same side of the upper surface of the plurality of support plates 5.

[0029] On the one hand, after the bottom plate is placed on the support plate 5, a gap exists between the bottom plate and the base 1, making it easy to remove, place, and move the bottom plate, thereby facilitating the docking of the bottom plate with the front axle vertical plate. On the other hand, the positioning strips 6 can position the bottom plate, so when docking the front axle vertical plate with the bottom plate, only the front axle vertical plate needs to be adjusted.

[0030] It should be noted that reinforcing ribs 7 are provided between the side panel positioning plate 2 and the horizontal support surface. To ensure the secure installation of the side panel positioning plate 2, reinforcing ribs 7 are provided between the side panel positioning plate 2 and the horizontal support surface. Furthermore, the outer edge of the axis positioning hole 4 has a chamfered structure. This chamfered outer edge of the axis positioning hole 4 forms a sloped surface, which facilitates the insertion of the axis hole positioning tube 3 into the axis positioning hole 4 and facilitates operation.

[0031] Furthermore, a plurality of positioning frames 8 are fixedly mounted on the horizontal support table, and positioning baffles 9 are provided on the positioning frames 8. The positioning baffles 9 are used to position the vertically arranged front axle welding plates.

[0032] Specifically, the positioning frames 8 are vertically installed on the horizontal support table, and a plurality of the positioning frames 8 are distributed in a straight line.

[0033] In this embodiment, when positioning the vertical plate of the front axle, the vertical plate of the front axle is slid along the length direction of the shaft hole positioning tube 3. When the side surface of the vertical plate of the front axle is in contact with the positioning baffle 9, the position adjustment of the vertical plate of the front axle is completed. At this time, the vertical plate of the front axle and the bottom plate can be directly welded, which greatly improves the welding efficiency of the front axle.

[0034] It should be noted that the spatial distribution of the positioning strip 6 and the positioning baffle 9 is pre-set according to the structure of the front axle. When the bottom plate is fitted with the positioning strip 6, and the vertical plate of the front axle slides along the axial hole positioning tube 3 and fits with the positioning baffle 9, the position docking between the vertical plate of the front axle and the bottom plate is completed. At this time, the vertical plate of the front axle and the bottom plate can be directly welded, which greatly improves the welding efficiency.

[0035] Compared with the prior art, the present invention has at least the following beneficial effects:

[0036] During the front axle welding positioning process, the utility model utilizes the cooperation of the axis positioning hole and the axis hole positioning tube to realize the rapid positioning of the axis of the front axle welding plate, which not only improves the welding quality of the front axle welding plate, but also improves the welding efficiency of the front axle welding plate. It has the characteristics of simple structure and convenient operation.

[0037] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
