[0002] The lengths of the workbenches and operation rooms used in automobile spraying workshops are generally more than 6 meters. Such ultra-long workbenches need to be fixed to the workshop floor, and the deformation of long workpieces and the flatness of the workshop floor both cause difficulties in leveling the workbench surface.

[0003] As Figure 4 shown in the figure, the leveling of the existing spraying workbench uses expansion bolts 4 to fix the grounding channel steel 5 to the workshop floor, and the horizontally arranged leveling channel steel 6 is buckled on the grounding channel steel 5. Through the fixed connection between the leveling channel steel 6 and the grounding channel steel 5, a horizontal plane with the leveling channel steel 6 as the reference is formed. Then, equal-height connecting support members 8 are fixed on the leveling channel steel 6, and a tabletop is installed on the top of the connecting support members 8 to achieve the horizontal setting of the workbench.

[0004] In terms of the existing technology, in order to prevent the leveling channel steel 6 from deforming due to its own weight, a lot of pads are needed to support the leveling channel steel 6 and the positions and heights of the pads are adjusted repeatedly. It is difficult to set the leveling channel steel 6 horizontally, resulting in inconvenient operation; in addition, the support members of the workbench are fixed on the horizontal stable frame formed by the grounding channel steel 5 and the leveling channel steel 6. The materials used to obtain the entire horizontal stable frame are more, and the manufacturing cost is high. Content of the Utility Model

Detailed Embodiments

[0018] In the following description, a large number of specific details are given to provide a more thorough understanding of the present utility model. However, it is obvious to those skilled in the art that the present utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the present utility model, some technical features known to the art are not described.

[0019] As Figure 1 shown, a leveling structure of a grounding workbench includes a grounding member 1, a leveling support member 2, and a tabletop 3. The grounding member 1 is fixed on the workshop floor through expansion bolts 4. A plurality of leveling support members 2 are installed on the grounding member 1, and the leveling support member 2 adjusts its relative position with the grounding member 1 through a leveling unit.

[0020] The present utility model can achieve the position setting of the leveling support member 2 by adjusting the leveling unit, so as to achieve the purpose that the tops of a plurality of leveling support members 2 are flush, enabling the tabletop 3 to be horizontally set regardless of the flatness of the workshop floor. The leveling operation of the leveling unit is simple, and compared with Figure 4 the traditional leveling structure, it saves more materials and has a lower manufacturing cost.

[0021] As Figures 2 to 3 shown, the leveling support member 2 includes a support main body 21, a leveling unit, and a connecting handle 26. The support main body 21 is in a bent sheet metal structure. The leveling unit and the connecting handle 26 are respectively arranged at the bottom and top of the support main body 21. The leveling unit contacts the grounding member 1, and the connecting handles 26 of a plurality of leveling support members 2 are connected through a connecting rod 27.

[0022] The bottom of the leveling support member 2 is provided with a leveling unit that cooperates with the grounding member 1. The leveling unit is used to adjust the vertical height of the leveling support member 2, which is the key to realizing that the tops of all leveling support members 2 are at the same horizontal position. The connection between the connecting handle 26 and the connecting rod 27 is to connect all the leveling support members 2 from being separated to being integrated, enhancing the connection stability of the workbench.

[0023] Among them, the leveling unit includes an adjusting frame 22, an adjusting nut 23, and an adjusting bolt 24. The adjusting frame 22 is welded to the bottom of the support main body 21. The adjusting nut 23 is welded to the adjusting frame 22. The adjusting bolt 24 passes through the adjusting frame 22 and is threadedly connected to the adjusting nut 23. The adjusting nut 23 contacts the grounding member 1.

[0024] An adjusting hole 25 is opened on the support main body 21. The regulation of the adjusting bolt 24 is completed by a tool, and the smooth operation of the tool requires the adjusting hole 25 to give way.

[0025] Specifically, the grounding part 1 has a three-segment U-shaped bending structure. The middle segment of the grounding part 1 is fixed to the workshop floor by an expansion bolt 4. The two side segments of the grounding part 1 are of unequal length. The bottom of the leveling support part 2 has a Z-shaped bending structure. The adjusting frame 22 is installed on the middle segment of the bottom of the leveling support part 2. The two side segments of the bottom of the leveling support part 2 are respectively connected to the two side segments of the grounding part 1. The connection between the grounding part 1 and the leveling support part 2 can be achieved by intermittent welding or rivet connection.

[0026] The grounding part 1 and the bottom of the leveling support part 2 form a horizontal stable frame, and the overlapping length of the grounding part 1 and the leveling support part 2 is greater than the connection threshold. The connection threshold is related to the height and thickness of the leveling support part 2. Taking the leveling support part 2 with a thickness of 40 mm and a height of 2 m as an example, the connection threshold is 3.5 cm. If the overlapping length of the grounding part 1 and the leveling support part 2 is too small, it will lead to connection failure. Especially when welding is selected, the deformation amplitude of the workpiece will affect the formation of the horizontal stable frame.

[0027] The top of the leveling support part 2 has a U-shaped bending structure. The connecting handle 26 is installed on the top of the leveling support part 2. A waist-shaped hole is opened on the connecting handle 26. The connecting rod 27 passes through the connecting handles 26 of several leveling support parts 2 and is limited by a circlip.

[0028] The setting of the waist-shaped hole allows the connecting rod 27 to pass through all the connecting handles 26, but it is not stressed vertically. However, the connecting rod 27 can limit all the leveling support parts 2 to be laterally flush, which is beneficial to the neat arrangement of all the leveling support parts 2.

[0029] When the utility model is in use, first, the expansion bolt 4 fixes the grounding part 1 to the workshop floor. Then, the leveling support part 2 with one end provided with the adjusting frame 22 is vertically inserted into the grounding part 1. Then, an adjusting tool is used to pass through the adjusting hole 25 and twist the adjusting bolt 24. Under the thread fit of the adjusting bolt 24 and the adjusting nut 23, the whole leveling support part 2 is jacked up or lowered until the height of the leveling support part 2 reaches the ideal position, and then the boundary line between the support main body 21 and the grounding part 1 is intermittently welded. Then, other leveling support parts 2 are set and welded so that the tops of adjacent leveling support parts 2 are at the same height. When all the leveling support parts 2 are installed, the connecting rod 27 is passed through all the connecting handles 26 and clamped on both sides of the connecting handle 26 by a circlip to complete the connection of several leveling support parts 2. Finally, the tabletop 3 is fixed to the top of the leveling support part 2.

[0030] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present utility model, various equivalent transformations can be made to the technical solutions of the present utility model, and these equivalent transformations all belong to the protection scope of the present utility model.
